In most cases, forward-looking statements may be identified by words such as “anticipate,” “may,” “will,” “could,” “should,” “would,” “expect,” “intend,” “plan,” “goal,” “contemplate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “seek,” “strategy,” “future,” “likely” or the negative or other variations on these words and other similar expressions. These statements, which may include, without limitation, projections regarding our future performance and financial condition, are made on the basis of management’s current views and assumptions with respect to future events. These statements speak only as of the date they were made, and we undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. We operate in a changing environment where new risks emerge from time to time and it is not possible for us to predict all risks that may affect us. The forward-looking statements are not guarantees of future performance, and the forward-looking statements, as well as our prospects as a whole, are subject to risks and uncertainties that could cause actual results to differ materially from those set forth in the forward-looking statements. These risks and uncertainties include, without limitation:

■the health of the U.S. housing market generally and changes in economic conditions that impact the size of the insurable mortgage market, the credit performance of our insured mortgage portfolio and our business prospects, including changes resulting from inflationary pressures, the higher interest rate environment and the risk of higher unemployment rates, as well as other macroeconomic stresses and uncertainties, including potential impacts resulting from geopolitical events;

■changes in the way customers, investors, ratings agencies, regulators or legislators perceive our performance, financial strength and future prospects;

■Radian Guaranty’s ability to remain eligible under the PMIERs to insure loans purchased by the GSEs;

■our ability to maintain an adequate level of capital in our insurance subsidiaries to satisfy current and future regulatory requirements;

■changes in the charters or business practices of, or rules or regulations imposed by or applicable to, the GSEs or loans purchased by the GSEs, or changes in the requirements for Radian Guaranty to remain an approved insurer to the GSEs, such as changes in the PMIERs or the GSEs’ interpretation and application of the PMIERs or other applicable requirements;

■the effects of the ERCF, which establishes a new regulatory capital framework for the GSEs, and which, as finalized, increases the capital requirements for the GSEs, and among other things, could impact the GSEs’ operations and pricing as well as the size of the insurable mortgage market;

■changes in the current housing finance system in the United States, including the roles of the FHA, the GSEs and private mortgage insurers in this system;

■our ability to successfully execute and implement our capital plans, including our risk distribution strategy through the capital markets and traditional reinsurance markets, and to maintain sufficient holding company liquidity to meet our liquidity needs;

■our ability to successfully execute and implement our business plans and strategies, including plans and strategies that may require GSE and/or regulatory approvals and licenses, that are subject to complex compliance requirements that we may be unable to satisfy, or that may expose us to new risks, including those that could impact our capital and liquidity positions;

■risks related to the quality of third-party mortgage underwriting and mortgage servicing;

■a decrease in the Persistency Rates of our mortgage insurance on Monthly Premium Policies;

■competition in the private mortgage insurance industry generally, and more specifically: price competition in our mortgage insurance business, including the prevalence of formulaic, granular risk-based pricing methodologies that are less transparent than historical rate-card-based pricing practices; and competition from the FHA and the VA as well as from other forms of credit enhancement, such as any potential GSE-sponsored alternatives to traditional mortgage insurance;

■U.S. political conditions and legislative and regulatory activity (or inactivity), including adoption of (or failure to adopt) new laws and regulations, or changes in existing laws and regulations, or the way they are interpreted or applied;

■legal and regulatory claims, assertions, actions, reviews, audits, inquiries and investigations that could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief that could require significant expenditures, new or increased reserves or have other effects on our business;

■the amount and timing of potential payments or adjustments associated with federal or other tax examinations;

8

■the possibility that we may fail to estimate accurately, especially in the event of an extended economic downturn or a period of extreme market volatility and economic uncertainty, the likelihood, magnitude and timing of losses in establishing loss reserves for our mortgage insurance business or to accurately calculate and/or project our Available Assets and Minimum Required Assets under the PMIERs, which could be impacted by, among other things, the size and mix of our IIF, future changes to the PMIERs, the level of defaults in our portfolio, the reported status of defaults in our portfolio (including whether they are subject to mortgage forbearance, a repayment plan or a loan modification trial period), the level of cash flow generated by our insurance operations and our risk distribution strategies;

■volatility in our financial results caused by changes in the fair value of our assets and liabilities, including with respect to our use of derivatives and within our investment portfolio;

■changes in GAAP or SAP rules and guidance, or their interpretation;

■risks associated with investments to grow our existing businesses, or to pursue new lines of business or new products and services, including our ability and related costs to develop, launch and implement new and innovative technologies and digital products and services, whether these products and services receive broad customer acceptance or disrupt existing customer relationships, and additional financial risks related to these investments, including required changes in our investment, financing and hedging strategies, risks associated with our increased use of financial leverage, which could expose us to liquidity risks resulting from changes in the fair values of assets, and the risk that we may fail to achieve forecasted results, which could result in lower or negative earnings contribution and/or impairment charges associated with intangible assets;

■the effectiveness and security of our information technology systems and digital products and services, including the risk that these systems, products or services fail to operate as expected or planned or expose us to cybersecurity or third-party risks, including due to malware, unauthorized access, cyberattack, ransomware or other similar events;

■our ability to attract and retain key employees;

■the amount of dividends, if any, that our insurance subsidiaries may distribute to us, which under applicable regulatory requirements is based primarily on the financial performance of our insurance subsidiaries, and therefore, may be impacted by general economic, competitive and other factors, many of which are beyond our control; and

■the ability of our operating subsidiaries to distribute amounts to us under our internal tax- and expense-sharing arrangements, which for our insurance subsidiaries are subject to regulatory review and could be terminated at the discretion of such regulators.

For more information regarding these risks and uncertainties as well as certain additional risks that we face, you should refer to the Summary of Risk Factors, to the more detailed discussion of our Risk Factors included in Item 1A, and to subsequent reports and registration statements filed from time to time with the SEC. We caution you not to place undue reliance on these forward-looking statements, which are current only as of the date on which we issued this report.

Summary of Risk Factors

Our business is subject to a number of risks, including risks that may prevent us from achieving our business objectives or may adversely affect our business, financial condition, results of operations, cash flows, and prospects. These risks are discussed more fully under “Item 1A. Risk Factors” of this Annual Report on Form 10-K and include, but are not limited to, the following material risks and uncertainties:

■Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity.

■Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy.

■Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.

■Legislation and administrative and regulatory changes and interpretations could impact our businesses.

■Our success depends on our ability to assess and manage our mortgage insurance underwriting risks; the mortgage insurance premiums we charge may not be adequate to compensate us for our liability for losses and the amount of capital we are required to hold against our insured mortgage risks. We expect to incur losses for future mortgage defaults beyond what we have reserved for in our financial statements.

■If the estimates we use in establishing mortgage insurance loss reserves are incorrect, we may be required to take unexpected charges to income, which could adversely affect our results of operations.

■Our Loss Mitigation Activity could negatively impact our customer relationships.

■Reinsurance may not be available, affordable or adequate to protect us against losses.

■If the length of time that our mortgage insurance policies remain in force declines, it could result in a decrease in our future revenues.

■Our delegated underwriting program may subject our mortgage insurance business to unanticipated claims.

■Our mortgage insurance business faces intense competition.

■Our NIW and franchise value could decline if we lose business from significant customers.

■The current financial strength ratings assigned to our mortgage insurance subsidiaries could weaken our competitive position and potential downgrades by rating agencies to these ratings and the ratings assigned to Radian Group could adversely affect the Company.

■Our business depends, in part, on effective and reliable loan servicing.

■We face risks associated with our contract underwriting business.

■A decrease in the volume of mortgage originations could result in fewer opportunities for us to write new mortgage insurance business and conduct our homegenius businesses.

■We are exposed to risks associated with our homegenius businesses that could negatively affect our results of operations and financial condition.

General

Overview

We are a mortgage and real estate services company. We provide mortgage insurance and other products and services to the real estate and mortgage finance industries primarily through two business segments—Mortgage Insurance and homegenius. While we manage and report on our segments separately, we take an enterprise approach under our “One Radian” strategy, which leverages the value of our employees across our diversified businesses to better serve our customers.

Our Mortgage Insurance segment aggregates, manages and distributes U.S. mortgage credit risk for the benefit of mortgage lending institutions and mortgage credit investors, principally through private mortgage insurance on residential first-lien mortgage loans, and also offers other credit risk management solutions, including contract underwriting, to our customers. Our homegenius segment offers an array of title, real estate and real estate technology products and services primarily to consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees.

In addition to these business segments, as an extension of our strategy to aggregate, manage and distribute U.S. mortgage credit risk, in late 2022 we began acquiring and distributing residential mortgage loans through Radian Mortgage Capital, our mortgage conduit. As of December 31, 2023, Radian Mortgage Capital’s operations are not yet material enough to constitute a reportable segment. See “All Other—Overview” for additional information on our mortgage conduit.

See Notes 1 and 4 of Notes to Consolidated Financial Statements for further details of our businesses. Also, in “Item 1A. Risk Factors,” see “Investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business subject us to additional risks and uncertainties.”

Radian Group serves as the holding company for our insurance and other subsidiaries, through which we offer our products and services, and does not have any operations of its own. Our principal executive offices are located at 550 East Swedesford Road, Suite 350, Wayne, PA 19087, and our telephone number is (215) 231-1000.

Mortgage Insurance

Overview

Private mortgage insurance plays an important role in the U.S. housing finance system because it promotes affordable homeownership, while helping to protect mortgage lenders, investors and the GSEs, who are the primary beneficiaries of our mortgage insurance, by mitigating default-related losses on residential mortgage loans. Generally, the loans we insure are made to home buyers who make down payments of less than 20% of the purchase price for their home or, in the case of refinancings, have less than 20% equity in their home.

For new home purchases, loans subject to mortgage insurance typically are provided to first-time homeowners, and therefore, private mortgage insurance plays an important role by providing prospective first-time home buyers the opportunity to purchase their first home (and to begin to accumulate equity) without having to put down 20% of the value of the home at closing. In many cases, especially in periods of rising home prices, saving for a 20% down payment could be difficult for first-time home buyers. Private mortgage insurance also facilitates the sale of these loans in the secondary mortgage market, most of which are currently sold to the GSEs.

The performance of our Mortgage Insurance business is particularly influenced by macroeconomic conditions and specific events that impact the housing finance and real estate markets, including seasonal fluctuations and other events that impact mortgage originations and the credit performance of our mortgage insurance portfolio, most of which are beyond our control, such as housing prices, inflationary pressures, unemployment levels, interest rate changes, the availability of credit and other national and regional economic conditions. In “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” see “Overview—Current Operating Environment” and “Key Factors Affecting Our Results—Mortgage Insurance.”

Our Mortgage Insurance business is subject to comprehensive regulation by state and federal regulatory authorities and the GSEs. As the largest purchasers of conventional mortgage loans, and therefore, the main beneficiaries of private mortgage insurance, the GSEs impose eligibility requirements, known as PMIERs, that private mortgage insurers must satisfy to be approved to insure loans purchased by the GSEs. These requirements and practices, as well as those of the federal regulators that oversee the GSEs and lenders, impact the operating results and financial performance of private mortgage insurers. See “Regulation” for a comprehensive description of the significant state and federal regulations and other requirements of the GSEs that are applicable to our businesses.

Mortgage Insurance Products

Primary Mortgage Insurance

Primary Mortgage Insurance represents our most common form of mortgage insurance execution. Based on market demand, we currently are providing Primary Mortgage Insurance on an individual loan basis as each mortgage is originated, but we also have the ability to provide Primary Mortgage Insurance on individual loans in an aggregate group of mortgages after they have been originated. We mainly write Primary Mortgage Insurance in a “first loss” position, where we are responsible for the first losses incurred on an insured loan subject to a policy limit. See “Mortgage Insurance Portfolio Characteristics—Mortgage Loan Characteristics.”

The terms of our Primary Mortgage Insurance coverage are set forth in a Master Policy that we enter into with each of our customers. Among other things, our Master Policies set forth the applicable terms and conditions of our mortgage insurance coverage, including among others: loan eligibility requirements; premium payment requirements; coverage terms, including cancellation of coverage; provisions for policy administration; mortgage servicing standards and requirements; exclusions or reductions in coverage under certain circumstances; insurance rescission and rescission relief provisions; claims payment and settlement procedures; and dispute resolution procedures. Our Master Policy forms, which are updated periodically, including in response to requirements issued by the GSEs, are filed in each of the jurisdictions in which we conduct business. Our Master Policy form was last updated on a broad basis in 2020, when most private mortgage insurers adopted a uniform master policy.

Primary Mortgage Insurance provides protection against mortgage defaults at a specified coverage percentage. When there is a valid claim under Primary Mortgage Insurance, our maximum liability typically is determined by multiplying the claim amount, which consists of the unpaid loan principal, plus past due interest and certain expenses associated with the default, by the coverage percentage. Depending on the circumstances, claims may be settled for the maximum liability or for other amounts. See “Defaults and Claims—Claims Management.” Although the Primary Mortgage Insurance we write protects the insured parties from a portion of losses resulting from mortgage defaults, it generally does not provide protection against property loss or physical damage, including damage caused by hurricanes or other severe weather events or natural disasters.

We wrote $52.7 billion and $68.0 billion of first-lien Primary Mortgage Insurance in 2023 and 2022, respectively. After taking into consideration insurance cancellations and other adjustments within our existing portfolio, our 2023 NIW resulted in IIF of $270.0 billion at December 31, 2023, compared to $261.0 billion at December 31, 2022. Our total direct Primary

15

Part I. Item 1. Business

Mortgage Insurance RIF was $69.7 billion at December 31, 2023, compared to $66.1 billion at December 31, 2022. For additional information, in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” see “Mortgage Insurance Portfolio—New Insurance Written” and “Insurance and Risk in Force.”

Other Mortgage Insurance Products

GSE Credit Risk Transfer. In the past, we participated in credit risk transfer programs developed by the GSEs as part of their programs to further distribute mortgage credit risk and increase the role of private capital in the mortgage market. These programs transfer additional credit risk on an excess-of-loss basis to insurance and reinsurance providers on pools of mortgage loans, which may contain loans that are already covered by private mortgage insurance.

After consideration of the collateral and capital required by the GSEs to support this RIF and based on our view of the projected returns on this business, we discontinued our participation in new credit risk transfer transactions from the GSEs in 2021. This business was conducted through our subsidiary, Radian Reinsurance, which in December 2022 novated all of its RIF related to credit risk transfer transactions to an unaffiliated third-party reinsurer and merged with Radian Guaranty. As a result of the novation, we have had no RIF under these credit risk transfer transactions since December 2022. In the future, our business strategy could again include participating in the GSEs’ credit risk transfer programs or providing other credit risk management solutions, subject to our views on projected business returns and other conditions.

Pool Mortgage Insurance. Prior to 2008, we wrote Pool Mortgage Insurance on a limited basis. At December 31, 2023, our total direct first-lien Pool Mortgage Insurance RIF was $226 million, as compared to $240 million at December 31, 2022, and represented less than 1% of our total direct first-lien insurance RIF. Our Pool Mortgage Insurance policies were privately negotiated and are separate from the Master Policies that we use for our Primary Mortgage Insurance. Subject to market demand, we could once again provide Pool Mortgage Insurance in the future.

Pricing

Primary Mortgage Insurance Premiums

We apply premium rates to our mortgage insurance products at the time coverage is requested by our customers, which is generally near the time of loan origination. Premiums for our mortgage insurance products are generally established based on performance models that consider a broad range of borrower, loan and property characteristics as well as current and projected market and economic conditions. Our premium rates are subject to regulation, and in most states where our insurance subsidiaries are licensed, the formulations by which we derive our premiums must be filed with the state insurance regulators, and in some cases approved by them, before their use. See “Regulation—State Regulation.”

We have developed our pricing strategy to manage the risk/return profile and maximize the long-term economic value of our insured portfolio by balancing credit risk, profitability and volume considerations in light of the current and projected competitive environment. We evaluate the projected long-term economic value of our insured portfolio by using a measure that incorporates expected lifetime returns for our insurance policies, taking into consideration projected premiums, credit losses, investment income, operating expenses, taxes and an assumed cost of capital. This projected economic value is then discounted to arrive at an estimated present value of the long-term economic value of our insured portfolio.

We use this economic value to assist us in evaluating various portfolio strategies and identifying opportunities to grow the economic value of our insured portfolio. Consistent with this strategy, our premium rates are based on a broad range of factors, including our cost of capital, competitive market conditions and the borrower, loan and property characteristics discussed above.

Premiums on our mortgage insurance products generally are written on either: (i) a recurring basis, which can be monthly or annual premiums, pursuant to our Monthly and Other Recurring Premium Policies or (ii) as a single premium generally paid at the time of loan origination pursuant to our Single Premium Policies. We also offer products where premiums are paid as a combination of an up-front premium at origination, plus a monthly installment. In addition, premiums may include a refundable component to be paid upon insurance cancellation. While the majority of our policies terminate when certain criteria are met, such as prescribed LTV levels, some of our products provide coverage for the life of the loan, subject to certain conditions. There are many factors that influence the types of premiums we receive, including, among others: (i) the preference of customers with whom we do business and (ii) the relative premium levels we and our competitors set for the various forms of premiums offered.

Mortgage insurance premiums can be funded through a number of methods, and while the coverage remains for the benefit of the insured lender or third-party beneficiary, the premiums may be paid by the borrower or by the lender. Borrower-paid Monthly and Other Recurring Premiums are generally paid to us as part of the borrower’s monthly mortgage payment, while borrower-paid premiums under our Single Premium Policies are paid to us at the time of closing on the home purchase. Lender-paid mortgage insurance premiums are paid by the lender and are typically passed through to the borrower in the form of a higher interest rate on the mortgage note.

The premium rates on a majority of our Monthly and Other Recurring Premium Policies were established as a fixed percentage of the initial loan balance for a set period of time (typically 10 years), after which the premium generally declines to

16

Part I. Item 1. Business

a lower fixed percentage for the remaining life of the policy. The premium rates on the remaining Monthly and Other Recurring Premium Policies within our insured portfolio were established as a fixed percentage of the loan’s amortizing balance over the life of the policy.

Historically, premiums in the mortgage insurance industry were primarily established through standard rate-cards filed with state insurance regulatory authorities, with limited flexibility to deviate. Beginning on a broad basis in 2019, the mortgage insurance industry began to widely use various pricing methodologies with differing degrees of risk-based granularity. Although these more recent pricing frameworks are based upon the same general risk attributes that historically have been a part of mortgage insurance pricing, they also incorporate more granular risk-based pricing factors based on multiple loan, borrower and property attributes.

The transition away from a predominantly standard rate-card based pricing model to the use of “black box” pricing frameworks throughout the mortgage insurance industry provides a more dynamic pricing capability that allows for more frequent pricing changes that can be implemented quickly and has contributed to a reduction in overall pricing transparency. Further, in addition to the growing proliferation of “black box” pricing, industry pricing practices in recent years have also included an increased use of customized rate plans for certain customers, pursuant to which rates may be awarded to certain customers based on a number of factors for only a limited period of time. With the increased prevalence of granular, “black box” pricing and the greater uniformity of master policy terms throughout the industry, pricing has become the predominant competitive market factor for private mortgage insurance, and an increasing number of customers are making their choice of mortgage insurance providers primarily based on the lowest price available for any particular loan.

We offer a spectrum of risk-based pricing solutions for our customers. This approach represents a continuation of our strategy to pursue multiple pricing delivery options that are best suited to a lender’s loan origination process and balanced with our own objectives for managing our volume of NIW and the economic value derived from our mortgage insurance portfolio. In “Item 1A. Risk Factors” see “Our mortgage insurance business faces intense competition.”

Underwriting

Mortgage loan applications are underwritten to determine whether they are eligible for our mortgage insurance. We perform this function directly or, alternatively, we delegate to our approved lenders the ability to underwrite the mortgage loans on our behalf.

Delegated Underwriting. Through our delegated underwriting program, we approve lenders to underwrite mortgage loan insurance applications based on our mortgage insurance underwriting guidelines. Each lender participating in the delegated underwriting program must be approved by our risk management group. Utilization of our delegated underwriting program enables us to meet lenders’ demands for immediate decisions on mortgage insurance coverage and increases the efficiency of their underwriting process. We use quality control sampling and performance monitoring to manage the risks associated with delegated underwriting. Under the terms of the program, we have certain rights to rescind coverage if there has been a deviation from our underwriting guidelines. For a discussion of these limited Rescission rights, see “Defaults and Claims—Claims Management—Rescissions.” As of December 31, 2023 and 2022, 71% and 70%, respectively, of our total first-lien IIF had been underwritten on a delegated basis.

Non-Delegated Underwriting. Approved lenders may submit mortgage loan applications to us so that we may perform the mortgage insurance underwriting. Some customers prefer our non-delegated underwriting program because we assume responsibility for underwriting the mortgage insurance and, subject to the terms of our Master Policies, generally have less ability to rescind coverage if there is an underwriting error. To improve efficiency in our underwriting process, we leverage loan application data and analytics to categorize mortgage insurance applications based on credit risk and underwriting complexity, which allows us to ensure a heightened focus on the higher-risk, complex applications. We also use quality control sampling, loan performance monitoring and training to manage the risks associated with our non-delegated underwriting program. As of December 31, 2023 and 2022, 25% and 26%, respectively, of our total first-lien IIF had been underwritten on a non-delegated basis.

Contract Underwriting. We also provide third-party contract underwriting services to our mortgage insurance customers pursuant to which we underwrite the mortgage loan for compliance with investor guidelines which, if necessary, may be separate from or in addition to underwriting for our mortgage insurance eligibility. Generally, we offer limited indemnification to our contract underwriting customers. To manage the risks associated with contract underwriting, we train our underwriters, require them to complete continuing education and routinely audit performance to monitor the accuracy and consistency of underwriting practices. As of both December 31, 2023 and 2022, 4% of our total first-lien IIF had been underwritten through contract underwriting.

Mortgage Insurance Portfolio Characteristics

Direct Risk in Force

Exposure in our mortgage insurance business is measured by RIF, which for Primary Mortgage Insurance is equal to the unpaid principal balance of the loan multiplied by our insurance coverage percentage. See “Item 7. Management’s Discussion

17

Part I. Item 1. Business

and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio—Insurance and Risk in Force” for additional information about the composition of our Primary RIF.

We analyze our mortgage insurance portfolio in a number of ways to identify potential concentrations or imbalances in risk dispersion. We believe that, among other factors, the credit performance of our mortgage insurance portfolio is affected significantly by:

■general economic conditions (in particular, interest rates, home prices and unemployment);

■the characteristics of the loans insured, including but not limited to the amount of equity borrowers have in their properties, the borrowers’ credit characteristics, the size of the loans and the age and performance history of the loans;

■the geographic dispersion and other characteristics of the properties securing the insured loans, such as the primary purpose of the properties and the condition of local housing markets, including whether the properties are increasing or decreasing in value over time;

■the quality of loan underwriting and servicing; and

■the number of borrowers and credit characteristics of the borrower(s).

Persistency Rate

The Persistency Rate, which measures the percentage of IIF that remains in force over a period of time, has a significant impact on our revenues and our results of operations. Because premiums on our Recurring Premium Policies are earned over time, higher Persistency Rates on these policies increase the premiums we receive and generally result in increased profitability and returns. Conversely, assuming all other factors remain constant, higher Persistency Rates on Single Premium Policies lower the overall returns on these products, as the premium revenue for our Single Premium Policies is received near the time the loan is originated and is the same regardless of the actual life of the insurance policy.

The Persistency Rate incorporates the impact that policy cancellations have on our IIF. Provided that all required premiums are paid, coverage for a loan under our Master Policy generally will be canceled on the first of the following to occur: (i) the loan insured under the certificate is paid in full, including in the event of a refinance transaction; (ii) we settle a claim with respect to the certificate; (iii) we act upon the insured’s or its servicer’s instruction to cancel coverage under the certificate, including as may be required by the HPA or pursuant to GSE guidelines; (iv) the term of coverage expires under the premium plan or upon the terms specified in the certificate; or (v) we cancel or rescind coverage or deny a claim under the certificate. For more information, in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” see “Key Factors Affecting Our Results—Mortgage Insurance—IIF and Related Drivers” and “Mortgage Insurance Portfolio—Insurance and Risk in Force.”

Historically, there has been a close correlation between interest rates and Persistency Rates. Higher interest rate environments generally decrease refinancings, which decrease the cancellation rate of our insurance and positively affect our Persistency Rates. See “Regulation—Federal Regulation—Mortgage Insurance Cancellation” for more information regarding cancellation and termination requirements for borrower-paid private mortgage insurance meeting certain criteria under the HPA.

Geographic Dispersion

Radian Guaranty is authorized to write mortgage insurance in all 50 states, the District of Columbia and Guam. We have a geographically diversified mortgage insurance portfolio, and we proactively monitor the portfolio for concentration risks at both the state level and metropolitan area level known as Core Based Statistical Areas (“CBSAs”). As of December 31, 2023, our largest state concentration was in Texas, which represented 10.0% of RIF, and our largest CSBAs concentration was the New York-Newark-Jersey City metropolitan area, which represented 5.3% of RIF. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio—Insurance and Risk in Force—Geographic Dispersion” for additional information about the geographic dispersion of our direct Primary Mortgage Insurance.

In “Item 1A. Risk Factors,” also see “The credit performance of our mortgage insurance portfolio is impacted by macroeconomic conditions and specific events that affect the ability of borrowers to pay their mortgages” and “Climate change and extreme weather events could adversely affect our businesses, results of operations and financial condition.”

Mortgage Loan Characteristics

In addition to geographic dispersion, factors that contribute significantly to our overall risk diversification and the credit quality of our RIF include, among others, the factors affecting the credit performance of our mortgage insurance portfolio, as discussed above under “Direct Risk in Force,” as well as our mix of mortgage insurance products, the quality of loan underwriting and our risk management practices. In evaluating the credit quality of our portfolio and assessing our risk of loss, as well as in developing our pricing and risk management strategies, we consider a number of borrower, loan and property characteristics, including LTV and FICO score, as well as a number of other loan and property characteristics, including,

18

Part I. Item 1. Business

without limitation, debt-to-income ratio, average loan size, property type, occupancy type, loan type and term, loan purpose and number of borrowers. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Mortgage Insurance Portfolio” for additional information about the credit quality and characteristics of our direct Primary Mortgage Insurance.

Defaults and Claims

Defaults

In our mortgage insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer. We consider a loan to be in default for financial statement and internal tracking purposes upon receipt of notification by servicers that a borrower has missed two monthly payments. Defaults can occur due to a variety of specific events affecting borrowers, including death or illness, divorce or other family problems, unemployment, factors impacting economic conditions (e.g., regional economic disruptions or disaster related events such as epidemics/pandemics, hurricanes, floods, tornadoes and wildfires) or other events. Regional economic disruptions derived from natural disasters may be exacerbated by climate change and related environmental factors, which could increase the frequency, scope and intensity of such disasters.

The default rate in our mortgage insurance business is subject to seasonality. Historically, our mortgage insurance business experiences a fourth quarter seasonal increase in the number of defaults and a first quarter seasonal decline in the number of defaults and increase in the number of Cures. While historically this has been the case, macroeconomic factors in any given period may influence the default rate in our mortgage insurance business more than seasonality.

Following the outbreak of the COVID-19 pandemic, a number of governmental efforts to implement programs designed to assist individuals and businesses impacted by the COVID-19 virus affected the defaults in our mortgage insurance portfolio, which increased significantly in 2020 but have since declined. These efforts included the CARES Act which provided that, upon request by borrowers of federally backed mortgage loans who attested to financial hardship related to the pandemic, including with respect to loans purchased by the GSEs, mortgage servicers were required to provide these borrowers with up to 180 days forbearance on their mortgage payments (which could be extended for an additional 180 days upon request) without requiring validation by the borrowers of their hardship. While the GSEs adopted temporary changes to their servicing policies to incorporate COVID-19-related forbearance plan flexibilities, in November 2023, the GSEs began the phased retirement of these servicing policies, including discontinuing new enrollments of COVID-19-related forbearance plans, and are reverting to the pre-COVID-19 policies as specified in their servicing guides. As of December 31, 2023, 24% of our primary loans in default remain in a COVID-19-related forbearance program. See “Regulation—Federal Regulation—CARES Act and GSE COVID-19 Forbearance.”

Defaulted loans that fail to become current, or “cure,” may result in a claim under our mortgage insurance policies. The rate at which defaults cure, or do not go to claim, depends in large part on a borrower’s financial resources and circumstances (including whether the borrower is eligible for a loan modification), local housing prices (i.e., whether borrowers are able to cure defaults by selling the property in full satisfaction of all amounts due under the mortgage), interest rates, unemployment, inflationary pressures and other factors impacting economic conditions.

In our first-lien Primary Mortgage Insurance business, in order to submit a claim, the insured must first either acquire title to the property (typically through a foreclosure proceeding) or we must approve a third-party sale of the property. The time for a lender to acquire title to a property through foreclosure varies depending on the state, and in particular whether a state requires a lender to proceed through the judicial system to complete the foreclosure. Claim activity is not spread evenly throughout the coverage period of a book of business. Historically, except during periods of economic distress, we have experienced relatively few claims during the first two years following issuance of a policy.

Following the onset of the COVID-19 pandemic, the average time for us to receive a claim increased as a result of COVID-19-related relief programs discussed above, along with temporary foreclosure and eviction moratoriums for residential mortgagors with certain federally or GSE-backed mortgages that were required under the CARES Act. Even as COVID-19 forbearances end, federal law requires servicers to discuss other forbearance and loss mitigation options with their borrowers and afford additional protections to borrowers before their loans are referred to foreclosure which is also impacting the length of time for us to receive a claim. Although these moratoriums have now expired, they have significantly impacted the claims process since 2020 by preventing the procedural steps necessary for a claim under our insurance policies to be filed. While foreclosure filings have resumed, foreclosure activity remains lower than it was prior to the COVID-19 pandemic. In “Item 1A. Risk Factors,” see “If the estimates we use in establishing mortgage insurance loss reserves are incorrect, we may be required to take unexpected charges to income, which could adversely affect our results of operations.”

For Pool Mortgage Insurance, which represents less than 1% of our RIF at December 31, 2023, our policies typically require the insured to not only acquire title to the property, but also to actively market and ultimately liquidate the property before filing a claim, which generally lengthens the time between a default and a claim submission.

In addition to claim volume, Claim Severity is another significant factor affecting losses. We calculate the Claim Severity by dividing the claim paid amount by the original coverage amount. Factors that impact the severity of a claim include, but are not limited to, the size of the loan, the amount of mortgage insurance coverage placed on the loan, the amount of time

19

Part I. Item 1. Business

between default and claim during which we are expected to cover certain interest (capped at three years under our recent Master Policies and capped at two years under our Master Policies prior to 2014) and expenses, and the impact of our Loss Mitigation and other loss management activities with respect to the loan.

Home price appreciation as well as pre-foreclosure sales, acquisitions and other early workout efforts help to reduce overall Claim Severity, as do actions we may take to reduce a claim payment due to servicer negligence, as discussed below in “Claims Management.” See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Mortgage Insurance—Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Expenses—Provision for Losses.”

Claims Management

Our claims management process is focused on analyzing and processing claims to ensure that we pay valid claims in accordance with our policies. Our mortgage insurance claims management department pursues opportunities to mitigate losses both before and after claims are received.

In our mortgage insurance business, upon receipt of a valid claim, we have a range of settlement options for calculating the claim amount (also referred to as calculated loss), as set forth in our Master Policies. We can settle a valid claim with the “Percentage Option” by paying the maximum liability and allowing the insured lender to keep title to the property. For this purpose, the maximum liability is determined by multiplying (x) the claim amount (which consists of the unpaid loan principal, plus past due interest for a period of time specified in our Master Policies, plus certain expenses associated with the default, and minus certain deductions) by (y) the applicable coverage percentage. We also have the following alternative settlement options under our Master Policies:

(i)Third-Party Sale/Approved Sale Option: Subject to any reduction provided for in our Master Policies, we may pay the claim amount (not to exceed the lender’s entire loss or our maximum liability under the Percentage Option) by taking into account the net proceeds received by the lender following an approved sale, including a “short sale” or “deed-in-lieu” transaction;

(ii)Acquisition Option: Subject to any reduction provided for elsewhere in our Master Policies, we may pay the entire claim amount (as described above but without application of the coverage percentage) and acquire good and marketable title to the property; or

(iii)Anticipated Loss Option: In certain circumstances, as outlined in our Master Policies, this claim settlement option is primarily based on the claim amount minus the net proceeds we reasonably anticipate would be generated if the property, in its original condition on the effective insurance commitment date, reasonable wear and tear excepted, were sold to a third party for fair market value.

Approved sales in which the underlying property has been sold for less than the outstanding loan amount are commonly referred to as “short sales.” Although short sales could have the effect of reducing our ultimate claim obligation, in many cases, notwithstanding the short sale, we will continue to be obligated to pay a claim in an amount that is equal to the maximum liability amount under the Percentage Option.

Under our Master Policies, we retain the right to consent prior to consummation of any short sale. We have entered into agreements with each of the GSEs pursuant to which we delegate to the GSEs our prior consent rights with respect to short sales on loans owned by the GSEs, as long as the short sales meet applicable GSE guidelines and processes for short sales and subject to certain other factors set forth in these agreements.

We also provide for limited delegation authority to certain loan servicers for short sales under specific circumstances. For loans that are not owned by the GSEs and for which we have not granted specific delegation authority to the loan servicer, we perform an individual analysis of each proposed short sale and provide our consent to these sales when appropriate. Historically, we have consented to a short sale only after reviewing various factors, including among other items, the sale price relative to market and the ability of the borrower to contribute to any shortfall in the sale proceeds as compared to the outstanding loan amount.

After a claim is received, our loss management specialists may focus on:

■a review to determine compliance with applicable loan origination programs and our Master Policy requirements, including: (i) whether the loan qualified for insurance at the time the certificate of coverage (i.e., policy) was issued; (ii) whether the insured has satisfied its obligation in meeting all necessary conditions in order for us to pay a claim, including submitting all necessary documentation in connection with the claim (commonly referred to as “claim perfection”); and (iii) whether the loan was appropriately serviced in accordance with the standards set forth in our Master Policies;

■analysis and prompt processing to ensure that valid claims are paid in an accurate and timely manner;

■responses to loss mitigation opportunities presented by the insured and/or servicer; and

■management and disposal of acquired real estate.

20

Part I. Item 1. Business

Radian Guaranty has entered into a Factored Claim Administration Agreement with Fannie Mae that applies to certain loans owned by Fannie Mae that were insured under our Master Policies for which a claim is submitted on or after October 1, 2018. Pursuant to the agreement, for the loans subject to the agreement, Radian Guaranty will determine the amount of covered expenses forming part of a loss (other than unpaid principal balance and delinquent interest) using agreed upon model-based expense factors. The expense factors are based on certain characteristics of each covered loan, including the unpaid principal balance at the time of default, property type and location, and property disposition.

Claim Denials

We have the legal right under our Master Policies to deny a claim under certain conditions, such as when the loan servicer does not produce documents necessary to perfect a claim (e.g., evidence that the insured has acquired title to the property) within the time period specified in our Master Policies. Most often, a Claim Denial is the result of a servicer’s failure to provide the loan origination file or other critical servicing documents for review.

If, after multiple requests by us, the loan origination file or other servicing documents are not provided to us, we generally deny the claim. If we deny a claim, we may continue to allow the insured the ability to perfect the claim for a limited period of time, as specified in our Master Policies. If the insured successfully perfects the claim on a timely basis, we will process the claim, including, as appropriate, by conducting a review of the loan file to ensure that underwriting and loan servicing were conducted properly.

If, after completion of this process, we determine that the claim was not perfected, other conditions precedent to coverage have not been met, or any exclusions apply, the insurance claim is denied and we consider the Claim Denial to be final and resolved. Although we may make a final determination with respect to a Claim Denial, it is possible that after we have denied coverage a legal challenge to our decision may be brought within a period of time specified under the terms of our Master Policies.

Rescissions

Mortgage insurance master policies generally protect mortgage insurers from the risk of material misrepresentations and fraud in the origination of an insured loan by establishing the right, under certain conditions, to unilaterally rescind coverage. Under the terms of our Master Policies, typical events that may give rise to our right to rescind coverage include: (i) we insured a loan in reliance upon an application for insurance that contained a material misstatement, misrepresentation or omission, whether intentional or otherwise, or that was issued as a result of an act of fraud or (ii) we find that there was negligence in the origination of a loan that we insured. We also have rights of Rescission arising from a breach of the insured’s representations and warranties that are contained in our Master Policies or endorsements thereto and are required with our delegated underwriting program.

If we rescind coverage based on a determination that a loan did not qualify for insurance, we provide the insured with a period of time to challenge or rebut our decision. If a rebuttal to our Rescission is received and the insured provides additional information supporting the continuation (i.e., non-rescission) of coverage, we will re-evaluate our original determination. If the additional information supports the continuation of coverage, the insurance is reinstated and if there is a claim, it proceeds to the next step in our claims review process. Otherwise, if we determine that the loan did not qualify for coverage, the insurance policy is rescinded (and we issue a premium refund under the terms of our Master Policies), and we consider the Rescission to be final and resolved. Although we may make a final determination internally with respect to a Rescission, it is possible that a legal challenge to our decision to rescind coverage may be brought after we have rescinded coverage during a period of time that is specified under the terms of our Master Policies.

We have incorporated provisions into our Master Policies since 2014 that generally provide Rescission relief based on the number of months that borrowers remain current on their mortgage loans. As a consequence, our rights to conduct Loss Mitigation Activity involving Rescission as a remedy generally are more limited under these Master Policies as compared to our prior Master Policies. Our more recent Master Policies continue to include certain life-of-loan reservation of Rescission rights specified in the Master Policy, including fraud and certain patterns of fraud. In “Item 1A. Risk Factors,” see “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

Claim Curtailments

We depend on third-party servicing of the loans that we insure. Servicers are responsible for being the primary contact with borrowers regarding their loans, and we generally do not have first-party contact with borrowers. Dependable loan servicing is necessary for, among other things, timely billing and premium payments to us and effective loss mitigation opportunities for delinquent or near-delinquent loans. As such, proper loan servicing is critical to the performance of our insured mortgage portfolio, especially when borrowers are experiencing difficulty paying their mortgages.

Our Master Policies require servicers to service our insured loans in a reasonable, prudent manner consistent with the highest standards of servicing in use in the residential mortgage industry, and we have rights under our Master Policies to

21

Part I. Item 1. Business

curtail, and in some circumstances, deny claims due to servicer negligence. Examples of servicer negligence may include, without limitation:

■a failure to report information to us on a timely basis as required under our Master Policies;

■a failure to pursue loss mitigation opportunities presented by borrowers, realtors and/or any other interested parties;

■a failure to pursue loan modifications and/or refinancings through programs available to borrowers;

■an undue delay in presenting claims to us (including as a result of improper handling of foreclosure proceedings), which increases the interest or other components of a claim we are required to pay;

■a failure to initiate and diligently pursue foreclosure or other appropriate proceedings within the timeframe specified in our Master Policies; and

■a failure to follow applicable foreclosure bidding instructions.

Although we could seek post-claim recoveries from the beneficiaries of our Master Policies if we later determine that a claim was not valid, because our loss mitigation process is designed to ensure compliance with our Master Policies prior to payment of a claim, historically, we have not sought recoveries from the beneficiaries of our Master Policies once a claim payment has been made.

From time to time, claims management may result in disputes with our customers that ultimately produce litigation or other legal proceedings. See Note 13 of Notes to Consolidated Financial Statements.

homegenius

Overview

Our homegenius businesses are comprised of title, real estate and real estate technology products and services. Through this business segment, we offer an array of products and services to market participants across the real estate value chain, which primarily include consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees. We believe that the combination of this broad set of products and services, together with our mortgage credit products and solutions offered by our other businesses, is unique and positions us to satisfy the multiple needs of our customers while serving as a more valuable business partner.

The macroeconomic conditions and specific events that impact the housing, mortgage finance and related real estate markets also affect the demand for the products and services we offer through our homegenius businesses. Sales volume in our homegenius businesses varies based on the overall activity in the housing and mortgage finance markets and the health of related industries. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—homegenius” for additional information.

Products and Services Offered

Title

As a national title underwriter, we provide a comprehensive suite of insurance and non-insurance title and real estate settlement services to mortgage lenders, mortgage investors and the GSEs as well as directly to consumers for residential mortgage loans. To date, our primary source of new title policies has been for refinance transactions and, as such, beginning in the second quarter of 2022 we experienced a significant decrease in new title policies due to the industrywide decrease in refinance volumes resulting from inflationary pressures and the higher interest rate environment. More recently, we have increased our focus on expanding our title service offerings to focus on residential purchase, REO and home equity transactions.

Title insurance is a contract of indemnity for losses stemming from a covered defect in title to real property, such as adverse ownership interests, liens, or other encumbrances, that predates the policy and is not otherwise excluded or excepted from coverage.

Losses on policies occur in the form of claims payouts and/or the cost of defending or establishing title. Title claims may arise from a number of factors, such as title search and examination errors, fraud, forgery, incorrect legal descriptions, and failure to identify existing liens. Subject to certain conditions, title insurers generally are also responsible for the cost of defending the insured in litigation alleging covered title defects, regardless of the merits of the allegations.

Real Estate

We provide our customers with real estate asset management services. These services include:

■managing REO properties owned primarily by financial institutions and mortgage investors;

22

Part I. Item 1. Business

■providing a full range of services for the benefit of the single-family rental asset class, which includes entities purchasing or building properties and employing a “rent-to-own” and “build-to-rent” business strategy, including by facilitating the property valuation and diligence services needed to support single-family rental warehouse lending and securitization activity; and

■offering a web-based asset management workflow solution to assist our customers in managing REO assets, rental properties, due diligence for bulk acquisitions, loss mitigation efforts and short sales.

In addition, through our licensed real estate broker subsidiary, homegenius Real Estate, we also provide a suite of real estate valuation products and services to lenders, servicers, investors and GSEs, including broker price opinions (i.e., price estimates on properties provided by real estate brokers familiar with a particular market) and various technology-enabled valuations.

Real Estate Technology

In addition to the services described above, we have developed a proprietary real estate technology platform to provide to lenders, real estate brokerages and corporate employers, in each case for the benefit of their customers, potential customers or employees, which is offered primarily through our licensed real estate broker subsidiary, homegenius Real Estate. This platform delivers a configurable experience designed to engage and support consumers across the real estate lifecycle.

These digital services and solutions include: national home search capabilities using unique data and photo search experiences; interactive valuation estimates; title services; a service to match interested homebuyers with local real estate agents; and ongoing interactions subsequent to home purchase, including consideration of home equity lending options.

Revenue Drivers

Our homegenius segment is dependent upon overall activity in the mortgage finance and real estate markets, as well as the overall health of the related industries. Due, in part, to the transactional nature of the business, revenues for our homegenius segment are subject to fluctuations from period to period, including fluctuations that reflect the seasonal volume fluctuations in these markets. Sales volume is also affected by the number of competing companies and alternative products offered in the market. In “Item 1A. Risk Factors,” see “We are exposed to risks associated with our homegenius businesses that could negatively affect our results of operations and financial condition.”

We earn net premiums on title insurance written by Radian Title Insurance. For our other homegenius offerings, we primarily use fixed-price contracts, pursuant to which we agree to perform the specified services and deliverables for a pre-determined per-unit price or ongoing service fee. For a portion of our real estate asset management services, we also utilize percentage-of-sale contracts, under which we are paid a contractual percentage of the sale proceeds upon the sale of each property.

In most cases, our contracts with our clients do not include minimum volume commitments and can be terminated by them at any time. The majority of our current homegenius revenues are transactional in nature and are generated in connection with securitizations, real estate purchases and sales or other transactions.

For additional information on the most significant factors affecting our homegenius businesses, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—homegenius.”

All Other

Overview

All Other activities include: (i) income (losses) from assets held by Radian Group, our holding company; (ii) related general corporate operating expenses not attributable or allocated to our reportable segments; and (iii) certain new business opportunities and other immaterial activities, the majority of which are currently activities associated with our mortgage conduit business conducted through Radian Mortgage Capital.

In 2022, we launched Radian Mortgage Capital to expand our capabilities to participate in the mortgage market to aggregate, manage and distribute residential credit risk. Radian Mortgage Capital, a mortgage conduit, acquires residential mortgage loans with the intention of then either selling the loans directly to mortgage investors, including the GSEs, or distributing them into the capital markets through private label securitizations, with the option to retain and manage structured components of the underlying credit risk. Radian Mortgage Capital is licensed in 49 states and the District of Columbia and positioned to purchase and hold residential mortgages and servicing rights on a nationwide basis.

In light of current market conditions, we have been measured in our approach with our mortgage conduit. Radian Mortgage Capital purchased $221 million and $4 million of mortgage loans during 2023 and 2022, respectively, and, to date, has only executed the distribution of loans through whole loan sales. Subject to market conditions, Radian Mortgage Capital

23

Part I. Item 1. Business

also expects to distribute the loans into the capital markets through private label securitizations in the future. As of December 31, 2023 and 2022, Radian Mortgage Capital owned $33 million and $4 million, respectively, of mortgage loans held for sale. See Note 7 of Notes to Consolidated Financial Statements for additional details.

See Note 4 of Notes to Consolidated Financial Statements for additional information regarding the basis of our segment reporting, including the related allocations.

Competition

Mortgage Insurance

We operate in the highly competitive U.S. mortgage insurance industry. Our competitors primarily include other private mortgage insurers and federal and state governmental agencies, principally the FHA and VA.

Including us, there are currently six active participants in the private mortgage industry that are approved and eligible to write business for the GSEs. The other participants are:

■Arch Capital Group Ltd. (includes both Arch Mortgage Insurance Company and United Guaranty Residential Insurance Company);

■Enact Holdings, Inc. (formerly Genworth Mortgage Holdings, Inc.);

■Essent Group Ltd.;

■MGIC Investment Corporation; and

■NMI Holdings, Inc.

We compete directly with other private mortgage insurers primarily on the basis of price, underwriting guidelines, overall service, customer relationships, perceived financial strength (including comparative credit ratings) and reputation. Overall customer service competition in our mortgage insurance business is based on, among other things, effective and timely delivery of products, timeliness of claims payments, customer connectivity, timely and accurate administration of policies, training, loss mitigation efforts and management and field service expertise.

For Radian, customer service also includes our ability to offer products and services through our other businesses that are relevant to our mortgage insurance customers and complement our mortgage insurance products.

Pricing has always been competitive in the mortgage insurance industry, but as discussed under “Mortgage Insurance—Pricing,” with the increased prevalence of granular, “black box” pricing and custom rate cards, and the greater uniformity of master policy terms throughout the industry, pricing has become the predominant competitive market factor for private mortgage insurance. We monitor various competitive and economic factors while seeking to enhance the long-term value of our mortgage insurance portfolio by balancing credit risk, profitability, and volume and capital considerations in developing our pricing strategies.

We establish our premium rates and seek to write a mix of business to manage the risk/return profile and maximize the long-term economic value of our mortgage insurance portfolio, taking into consideration the competitive environment. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—Mortgage Insurance—Premiums.” Based on publicly available information, we estimate that our share of NIW within the private mortgage insurance market was approximately 19% for 2023.

Certain of our private mortgage insurance competitors currently have better financial strength ratings than we have and/or are subsidiaries of larger corporations, which may give them a competitive advantage.

Private mortgage insurance competes for a share of the insurable mortgage market with the single-family mortgage insurance programs of the FHA and VA. Private mortgage insurance execution competes with the programs offered by the FHA on the basis of loan limits, pricing, credit guidelines, terms of our insurance policies and loss mitigation practices.

We believe that better execution for borrowers with higher FICO scores, in conjunction with the preference of certain lenders to execute through the GSEs, have served as competitive advantages for private mortgage insurance as compared to FHA insurance. The FHA’s share of the total insured mortgage market (which includes FHA, VA and private mortgage insurers) was reported to be 34% in 2023, compared to 27% in 2022. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting Our Results—Mortgage Insurance—NIW and Related Drivers.”

In February 2023, the FHA reduced its annual mortgage insurance premium by 0.30% for most new borrowers. While this pricing change did not have a material impact on our NIW volumes, the FHA could institute further pricing changes in the future, including additional changes to its annual premiums, a reduction in its upfront premiums and/or the elimination of the life-of-loan premium requirement for most FHA insured loans. It is uncertain if and when the FHA may pursue any additional pricing or other actions and what form they may take; however, any change that would improve FHA execution compared to execution through the GSEs with private mortgage insurance could negatively impact our NIW volume.

24

Part I. Item 1. Business

If the competitive position of the FHA is enhanced, it could have a negative effect on our ability to compete with the FHA. See “Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for a discussion of factors that could enhance the FHA’s competitive position relative to private mortgage insurance.

We also face competition from the VA. Based on publicly available information, the VA’s share of the total insured mortgage market was 22% in 2023, compared to 25% in 2022. We believe that the VA remains a strong participant in the overall market because of the number of borrowers that are eligible for the VA’s program, and because the VA insures 100% LTV loans, which is unavailable through private mortgage insurance and the FHA, and charges a one-time funding fee that can be included in the loan amount with no separate monthly payment.

In addition, as market conditions change, alternatives to traditional private mortgage insurance may become more prevalent, which could reduce the demand for private mortgage insurance. These alternatives have included structures commonly referred to as “investor paid mortgage insurance” in which affiliates of traditional mortgage insurers that are not subject to the PMIERs directly insure the GSEs against loss. For additional information about these structures, see “Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices.”

It is difficult to predict what other types of credit risk transfer transactions and structures or other forms of credit enhancement, including GSE-sponsored alternatives to traditional mortgage insurance, might be used in the future. If any of these alternatives were to displace standard primary loan level private mortgage insurance, the amount of insurance we write may be reduced and our future prospects could be negatively impacted.

In “Item 1A. Risk Factors,” see “Our mortgage insurance business faces intense competition.”

homegenius

We believe that through our homegenius segment we are positioned as a unique provider of an array of products and services to participants across the real estate value chain. While we are not aware of any other single company that provides a comparable range of services to the residential mortgage and real estate industries, our homegenius businesses have multiple significant competitors within each of its individual lines of business.

Significant competitors for our homegenius businesses include:

Title. The market for traditional title services is highly concentrated among four large companies with national scope: Fidelity National Financial, Inc.; First American Financial Corporation; Old Republic International Corporation; and Stewart Information Services Corporation. In addition, we compete with smaller national title service providers and a host of additional regional providers. In addition, the introduction of alternatives to traditional title insurance into the market such as the offering of attorney opinion letters in lieu of traditional title policies, which is being accepted by the GSEs, subject to certain conditions, could provide additional competition in the future. See “Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for additional information.

Real Estate and Real Estate Technology. Real estate technology and software companies such as: Ice Mortgage Technology; ClearCapital.com, Inc.; CoreLogic, Inc.; HouseCanary, Inc.; and Xome Inc.

Across all business lines in our homegenius segment, we believe we compete on the basis of technology, data access, industry expertise, price, service levels and relationships.

Customers

Mortgage Insurance

The principal customers of our mortgage insurance business are mortgage originators such as mortgage bankers, commercial banks, savings institutions, credit unions and community banks.

We actively monitor our customer concentration and regularly engage in efforts to diversify our customer base; however, the increasing use of custom rate cards for individual lenders in the mortgage insurance marketplace has increased the likelihood that a significant portion of NIW volume generated in any given period may be attributable to one or more customers. Our largest single mortgage insurance customer (including branches and affiliates) measured by NIW, accounted for 8% of NIW during 2023, compared to 8% and 14% in 2022 and 2021, respectively. The percentage of NIW generated by our top 10 customers was 34% in 2023. No single customer contributed earned premiums that accounted for more than 10% of our consolidated revenues in 2023, 2022 or 2021. In “Item 1A. Risk Factors,” see “Our NIW and franchise value could decline if we lose business from significant customers.”

25

Part I. Item 1. Business

homegenius

We have a broad range of customers in our homegenius segment, including many of our Mortgage Insurance customers, due to the products and services we offer across the mortgage and real estate value chain. Our principal customers (non-affiliated) are:

■Mortgage originators such as mortgage bankers, commercial banks, savings institutions, credit unions and community banks;

■Aggregators, issuers and investors in RMBS, whole loans and other mortgage-related debt instruments, including the GSEs, private equity and hedge funds, real estate investment trusts and investment banks;

■Single-family rental warehouse lenders, owner/operators, builders, capital markets institutional investors and securitization issuers;

■Mortgage servicers;

■Real estate brokers and agents;

■Corporations for their employees; and

■Consumers.

Our customers include many of the largest financial institutions and participants in the mortgage sector and, as such, our services revenue is concentrated among our largest customers. For the year ended December 31, 2023, the top 10 homegenius customers generated approximately 56% of the homegenius segment’s services revenue.

Sales and Marketing

Our sales and marketing efforts are focused on establishing, maintaining and growing valuable customer relationships. Given the range of solutions we offer across our businesses, our sales strategy includes seeking opportunities to expand our relationships with our existing customer base as well as with new customers. We have a core team of account managers who sell all products and solutions across our businesses, as well as sales teams with subject matter expertise in particular services and the related needs of the customers we serve.

Marketing and communications activities include direct marketing; print and digital advertising; digital marketing including email, web, content and social media; public relations and thought leadership; brand strategy and expression; event marketing including customer meetings, conferences and trade shows and other targeted initiatives designed to generate new sales opportunities, drive customer adoption of our services and retain our existing customers. We continue to adapt our sales and marketing efforts based on the current environment to offer tools and techniques to connect virtually and engage with current and potential customers.

All sales and marketing efforts are supported by functional areas that provide additional touch points for our customers. For example, our Inside Sales Team is responsible for managing and growing customer relationships and promoting increased customer adoption and our Client Success, Customer Service and Training Teams provide customized service as well as educational sessions to our customers.

Our approach to selling our products across our mortgage and real estate services businesses is intended to strengthen our relationships with customers, attract new customers and enhance our ability to compete.

Investment Policy and Portfolio

Our investment portfolio is our primary source of claims paying resources and also impacts our earnings. We seek to manage our investment portfolio within our targeted risk and return tolerances based on our current liability projections and business and economic outlook to maintain sufficient liquidity levels to satisfy our current and future operating requirements and other financial needs.

Our investment strategy uses an asset allocation methodology that takes into consideration regulatory constraints, our business environment and consolidated risks as well as current investment conditions. With respect to our fixed income investments, the following internal investment policy guidelines, among others, are applied at the time of investment and continually monitored.

26

Part I. Item 1. Business

Internal investment policy guidelines
NAIC Designation	Ratings Equivalent	Internal Policy
1	“A-” and above	At least 75% of the portfolio Fair Value
2	“BBB+” to “BBB-”	Not more than 25% of portfolio Fair Value
3 to 6	“BB+” and below	Not more than 10% of portfolio Fair Value

Our portfolio has been constructed to maximize long-term expected returns while maintaining an acceptable risk level. Our investment objectives are to utilize appropriate risk management oversight to optimize after-tax returns, while preserving capital. We calibrate the level of our short-term investments based on our overall investment portfolio duration, risk appetite and expected short-term cash requirements. In “Item 1A. Risk Factors,” see “Our success depends, in part, on our ability to manage risks in our investment portfolio.”

Our investment policies and strategies are subject to change, depending on business needs, current and potential future regulatory requirements, economic and market conditions and our then-existing or anticipated financial condition and operating requirements, including our current and future tax positions. The investments held at our insurance subsidiaries are subject to insurance regulatory requirements applicable to such insurance subsidiaries and investments held by Radian Guaranty are subject to the PMIERs. For example, insurance regulatory requirements address the types of assets that may be reported as admitted assets for statutory reporting purposes and limit how a mortgage insurer may invest its contingency reserve, and the PMIERs specify which type of assets are eligible to be counted as Available Assets. See “Regulation—Federal Regulation—GSE Requirements for Mortgage Insurance Eligibility.”

Oversight responsibility of our investment portfolio rests with management, and allocations are set by periodic asset allocation studies, calibrated by risk and after-tax return considerations. The risks we consider include, among others, duration, convexity, liquidity, market, sector, structural, interest rate and credit risks. As of December 31, 2023, we internally managed 10% of the investment portfolio (the portion of the portfolio largely consisting of U.S. Treasury securities, money market funds, equities, mortgage insurance-linked notes and other mortgage related assets, and certain exchange-traded funds), with the remainder primarily managed by three external managers. External managers are selected by management based primarily upon their ability to meet our investment goals and objectives, based upon factors such as historical returns and the stability of their management teams. Management’s selections of external managers are presented to, approved and monitored by the Finance and Investment Committee of our board of directors.

At December 31, 2023, our investment portfolio, including securities loaned to third-party borrowers under securities lending agreements, had a cost basis of $6.7 billion and a carrying value of $6.3 billion. At December 31, 2023, 95% of our investment portfolio was rated investment grade. The weighted-average duration of the assets in our investment portfolio as of December 31, 2023, was 4.1 years. For additional information about our investment portfolio, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Investment Portfolio,” as well as Notes 5 and 6 of Notes to Consolidated Financial Statements.

Although managed separately from the investment portfolio discussed above, beginning in 2022, we also purchase mortgage loans for resale in our mortgage conduit. See “All Other—Overview” and Note 7 of Notes to Consolidated Financial Statements for additional information on this business. In “Item 1A. Risk Factors,” see also “We face risks associated with our mortgage conduit business.”

Enterprise Risk Management

Risk Philosophy, Vision and Appetite

As a financial services organization, risk management is a critical part of our business. The following goals guide our strategy and actions as a risk management organization:

■Embed and continually reinforce a disciplined, corporate-wide risk culture that utilizes an understanding of risk/return trade-offs to drive quality decisions and achieve long-term, through-the-cycle profitability;

■Maintain credit, underwriting, pricing and risk/return disciplines based on sound data and analytics and continuous feedback throughout the organization;

■Proactively monitor business, counterparty, economic, housing and regulatory trends to identify and mitigate emerging risks;

■Continually refine analytical and technological capabilities, processes and systems to effectively identify, assess and manage risks; and

■Develop and leverage tools and capabilities to inform and optimize capital allocation within our risk appetite in support of our corporate strategy.

27

Part I. Item 1. Business

Risk Categories

Our risk appetite, or the amount of risk we are willing to take on in pursuit of value, is driven by our business strategy, which is established by executive management and overseen by our board of directors. We define our risk appetite qualitatively through the following key risk categories where strategic execution occurs: credit; financial; strategic; operational and regulatory and compliance. We do not treat reputational risk as a distinct category of risk; rather, we view reputational risk as pervasive throughout our entire risk portfolio, as each risk on its own can impact our reputation if not mitigated or managed properly.

Risk Governance

Board of Directors

Our board of directors is responsible for the general oversight of risks. Our board of directors seeks to understand and oversee the most critical risks relating to our business, allocates responsibilities for the oversight of risks among the full board and its committees, and reviews the systems and processes that management has in place to manage identified risks, as well as those that could arise in the future.

The board as a whole or through its Risk Committee and other standing committees, regularly meets with management to receive reports related to, among other risk-related items: (i) our Enterprise Risk Management (“ERM”) function regarding the most significant risks we are facing, and the steps being taken to assess, manage and mitigate those risks; (ii) our information security function regarding cybersecurity-related risks and our efforts to mitigate such risks; and (iii) our compliance programs and our efforts to embed a culture of compliance throughout the organization to encourage ethical behavior and mitigate risks of regulatory non-compliance. The full board further considers current and potential future strategic risks as part of its annual strategic planning session with management.

Executive Management

Our senior executive management team regularly monitors and discusses risks related to our businesses through various management committees. Our Pricing and Risk Committee, Capital and Liquidity Committee and Model Governance Committee (these committees collectively comprise our Asset Liability Committee) focus on identifying risks and decision making related to pricing, credit, capital, liquidity and model risk management, including risk/return analysis associated with different business opportunities. Other management committees focused on risk management include, but are not limited to, our ERM Council, Executive Information Security Committee, Enterprise Compliance Oversight Council, Resilience Executive Committee and Enterprise Information Governance Committee.

Integrated ERM Framework

We have adopted an integrated approach to risk management, which includes, among other things: (i) a centralized ERM function that is responsible for overseeing the process for risk identification, assessment, management and mitigation across the organization; (ii) an enterprise compliance function for overseeing regulatory compliance matters, policy governance and related risks; (iii) risk management functions embedded in our businesses; (iv) specialized risk committees with a focus on specific risks; and (v) an internal audit function that performs periodic, independent reviews and tests compliance with risk management policies, procedures and standards across the Company.

Our ERM framework is designed to provide executive management with the ability to identify and evaluate the most significant risks we face and to calibrate risk mitigation strategies to address challenges in the current business environment, as well as external factors that may create other risk exposures for our operations. In practice, our ERM function represents a cross-functional and enterprise-wide effort, consisting of subject matter experts and experienced managers, that utilizes a systematic method to identify, evaluate and monitor both known and emerging risks. Risk assessments and mitigation plans are developed to address these risks. Risk scoring and validation of the effectiveness of risk management plans through management reporting facilitate program sustainability and promote accountability for risk management activities throughout the Company.

As part of our ERM program, our businesses employ comprehensive risk management functions, which, in conjunction with oversight by the Risk Committee of our board of directors, are responsible for monitoring compliance with our risk-related policies, managing our insured portfolios and the mortgage loans we purchase through our mortgage conduit and communicating credit-related issues to management, our board of directors and our customers.

Information security is a significant operational risk for financial institutions such as Radian. To address this, our ERM program incorporates cybersecurity-related risks into our identification, evaluation and mitigation processes. In addition, we maintain an Information Security Program that is designed to protect our corporate data, including data we provide to others, as well as data entrusted to us by our customers and partners. For more information about our Information Security Program and other aspects of our cybersecurity governance and risk management, see “Item 1C. Cybersecurity.”

Part I. Item 1. Business

Mortgage Insurance Risk Management

Risk Origination and Servicing. We believe that understanding our business partners and customers is a key component of managing risk. Accordingly, we have a counterparty risk management team that leverages our customer and servicer segmentation framework so that we can more effectively perform ongoing monitoring of loan performance, underwriting quality and the risk profile and mix of business of a customer’s mortgage insurance applications. The counterparty risk management team monitors trends at the customer level, identifies customers who may exceed certain risk tolerances and shares meaningful performance data with our customers to help them improve. The team is also responsible for taking lender corrective action in the event we discover credit performance issues, such as high early payment default levels.

Portfolio Management. We have developed risk and capital allocation models to support our mortgage insurance business. These models provide comprehensive analytics that help us establish portfolio limits for product type, loan attributes, geographic concentrations and counterparties. We proactively monitor market concentrations across these and other attributes. We also identify, evaluate and negotiate potential transactions for terminating insurance risk and for distributing risk to third parties, including through reinsurance arrangements. See “Risk Distribution” below for more information about the use of reinsurance as a risk management tool in our mortgage insurance business. As part of our portfolio management function, we monitor and analyze the performance of various risks in our mortgage insurance portfolio. We use this information to develop our mortgage credit risk and counterparty risk policies, and as a component of our default and prepayment analytics.

Credit Policy. We maintain mortgage-related credit risk policies that reflect our tolerance levels regarding counterparty, portfolio and operational risks. Based on our policies and risk tolerances, our credit policy function develops and updates our mortgage insurance eligibility requirements and guidelines through regular monitoring of competitor offerings, GSE programs and GSE guideline updates, customer input regarding lending needs, analysis of historical performance and portfolio trends, quality assurance results and underwriter experience and observations. The credit policy function works closely with our mortgage insurance underwriters to ensure that underwriting decisions align with risk tolerances and policies.

Quality Assurance. Our quality assurance function supports our credit analytics function by auditing individual loan files to examine underwriting decisions for compliance with agreed-upon underwriting guidelines. These audits are conducted across loans submitted through our delegated and non-delegated underwriting channels in order to monitor underwriting quality for insurance certificates underwritten by our customers or our underwriters. We conduct independent re-verification of key mortgage insurance application data to minimize the possibility of misrepresentation. Our quality assurance team also conducts audits of our key operational functions, including claims, premium processing and customer care to ensure that our operational transactions are in compliance with our policies and procedures.

Loss Mitigation. We have a dedicated loss mitigation group that works with servicers to identify and pursue loss mitigation opportunities for loans in both our performing and non-performing (defaulted) portfolios. This includes regular surveillance and benchmarking of servicer performance with respect to default and loss mitigation workout reporting, borrower home retention efforts, foreclosure alternatives and foreclosure proceedings. Through our risk management function, we seek to hold servicers accountable for their performance and communicate to servicers identified best practices for servicer performance. See “Mortgage Insurance—Defaults and Claims—Claims Management” for more information.

Risk Modeling. Our risk modeling team uses analytical techniques to develop and maintain economic scenario generation models and loan level default and prepayment models across a wide range of risk management applications, including portfolio analysis, credit decision making, forecasting and loss reserving.

Risk Distribution. In our mortgage insurance business, we use reinsurance as a capital and risk management tool, including to lower the risk profile and financial volatility of our mortgage insurance portfolio through economic cycles. We have distributed risk through third-party quota share and excess-of-loss reinsurance arrangements, including through the capital markets using mortgage insurance-linked notes transactions. In recent years, we have expanded our risk distribution strategy in an effort to optimize the amounts and types of capital and risk distribution deployed against insured risk. The objectives of our risk distribution strategy include: (i) supporting our overall capital plan by reducing our cost of capital, increasing capital efficiency and enhancing our projected returns on capital and (ii) reducing portfolio risk and financial volatility through economic cycles. For additional information regarding our reinsurance programs, see Note 8 of Notes to Consolidated Financial Statements.

Title Insurance Risk Management

We take a prudent approach to assessing and managing risk in our title insurance business through the use of well-trained underwriters, stringent underwriting guidelines and the imposition of per file risk limits and third-party reinsurance on a per policy basis, over certain policy limits.

Underwriting and Quality Assurance. Our agents, underwriters and title examiners receive training and feedback in the examining and underwriting of residential and commercial title insurance for both refinance and purchase transactions. Certain title commitments are selected for further review to ensure that underwriting decisions comply with agreed-upon underwriting guidelines and that the policies are within single risk limits.

29

Part I. Item 1. Business

Credit Policy. We have developed and maintain policies for our title insurance business, which reflect our risk tolerance levels. Risk limits are imposed on selected loan types and reinsurance is currently required on all policies with loan amounts above a specified amount.

Ceded Reinsurance. In our title insurance business, we use reinsurance as part of our capital and risk management activities, including a loss portfolio transfer reinsurance agreement that transfers a portion of the risk associated with the legacy title insurance in our portfolio (insurance written prior to 2018 when we acquired our title insurance subsidiary) to a third party. We also currently maintain an excess-of-loss policy with a third-party reinsurer that covers losses on our entire title insurance legacy portfolio above a specified limit.

Mortgage Conduit Risk Management

Credit Policy. Our risk management team reviews and approves mortgage conduit loan programs, underwriting guideline changes and mortgage seller underwriting programs. Mortgage conduit loan programs are reviewed frequently and updated as needed to address changing market conditions and other factors.

Counterparty Risk. We maintain mortgage seller approval and recertification policies to evaluate and monitor, among other things, seller creditworthiness, capacity, and quality. Mortgage seller financial and other trends are also monitored, and appropriate mitigation actions are taken as warranted. Our counterparty risk management team has also developed risk thresholds for our mortgage conduit business that align with the Company’s overall risk and return tolerances.

Quality Assurance. Our quality assurance function audits a sample of individual loan files purchased by Radian Mortgage Capital to assess compliance with the applicable underwriting guidelines and regulatory compliance requirements. We conduct independent re-verification of key credit file data to protect against misrepresentation.

Secondary Marketing. We have a control framework with established standards, parameters and practices that apply to the purchase and sale of mortgage loan products by Radian Mortgage Capital. The controls are aligned with the Company’s risk and return tolerances through established authority levels, escalation triggers and governance over target pricing, margin limits, risk position limits and trade size limits. This framework governs Radian Mortgage Capital’s day-to-day management of market risk within profitability targets of its residential mortgage loan pipeline and ensures that Radian Mortgage Capital maintains a hedge coverage that is within the Company’s approved parameters.

Human Capital Management

For over 45 years at Radian, our products and services have responsibly helped millions of families achieve their dream of homeownership. This company-wide commitment to affordable, sustainable and equitable homeownership, along with our support of our customers, our employees and the communities where we live and work, defines who we are as an enterprise and aligns with our core organizational values: Deliver the Brand Promise, Innovate for the Future, Create Shareholder Value, Our People are the Difference, Do What’s Right and Partner to Win.

We value our employees by supporting a healthy work-life balance and a team-oriented, “One Radian” environment. We strive to offer competitive compensation and benefits programs as well as career development opportunities, while fostering a community where everyone feels included and empowered to do their best work and is encouraged to give back to their communities to make a social impact. As of December 31, 2023, we had approximately 1,100 employees of Radian Group and its subsidiaries.

Compensation and Benefits Program

Our compensation programs are designed to attract, retain and reward talented individuals from diverse backgrounds who possess the skills and qualities necessary to support our business objectives, demonstrate our values, assist in the achievement of our strategic goals and create long-term value for our stockholders. Our compensation programs include base salary, annual incentive bonuses and, for certain employees, other performance-related cash incentives, such as commissions, and long-term equity incentive awards.

Our annual short-term incentive or bonus program is designed and approved by the Compensation and Human Capital Management Committee of our board of directors to incent achievement of our financial objectives and execution of our strategic plan in alignment with our organizational values. Living our values and advancing our human capital management capabilities are considered as part of our employees’ performance evaluations and are taken into consideration in determining each employee’s annual short-term incentive award.

In addition to our cash and equity compensation programs, we offer eligible employees a comprehensive benefits package, including, among others, life and health (medical, dental and vision) insurance, paid time off, fertility assistance, paid parental leave and caregiver leave, a 401(k) plan with an employer matching contribution and tuition reimbursement. In addition, in order to support our employees and advance our mission to promote affordable, sustainable and equitable homeownership, we offer all eligible employees benefit reimbursements in our Radian mortgage insurance, title and agent referrals programs via our homebuyer perks benefits program.

Part I. Item 1. Business

Diversity, Equity and Inclusion

At Radian, we are committed to an inclusive and diverse workplace, as represented by our Employee Value Promise—We See You at Radian. We believe that an equitable and inclusive environment with diverse teams produces more creative solutions, results in more innovative products and services and is crucial to our efforts to attract and retain key talent.

We have an employee council, the Diversity, Equity and Inclusion (“DEI”) Council, that is sponsored by our CEO, led by senior management and comprised of leaders and employees from across the Company to advance the program and its efforts. In 2020, we created a framework for and launched Radian’s Employee Resource Group (“ERG”) program, which is an important aspect of Radian’s DEI efforts because it not only creates inclusive communities where employees feel support, but it enriches our overall company culture. Radian currently has five active ERGs: TrueColors, which brings together our LGBTQIA+ employees and allies; Women Heard, as our women and women’s advocate group; Vibrant Crossroads, which highlights intersectionality and multiculturalism; Without Limits, which represents our commitment to Neurodiversity inclusion; and Radian Salutes, supporting veterans, military service members, and military dependents.

We are committed to providing equal employment opportunities and promoting inclusive recruiting practices. In 2020, we trained all managers on unconscious bias and, in 2021, we hired a recruiter dedicated to DEI. We annually deploy mandatory DEI training for all employees. We also annually complete pay equity analyses in partnership with an external expert to provide an objective review of our pay practices.

We know that advancing a culture of inclusion takes every single employee. In 2022, we instituted an annual requirement for all employees to include a DEI objective as part of their annual performance goals, which serve as a basis for their short-term incentive award. By focusing all employees on the importance of our DEI efforts, we can continue to advance a culture of inclusion and respect.

At December 31, 2023, women represented 51% of our workforce, 44% of the direct reports to our Chief Executive Officer and 39% of our senior management team comprising officers at the Assistant Vice President level and above.

Talent Development and Employee Engagement

We invest in our people to provide opportunities for professional and career growth. Programs such as our talent development strategy, annual performance reviews that are focused in part on living our company values and succession planning are all important aspects of this investment. These processes help management identify and nurture top talent for leadership opportunities and support the growth and development of knowledge and skills of our employees, managers and leaders.

In order to measure engagement and culture across the organization, we use employee experience surveys. In addition to our experience surveys, we typically use employee pulse surveys and focus groups to gather employee feedback. We communicate the results of these surveys to our employees and incorporate the feedback into our human capital management strategies to ensure that we are being responsive to the needs and views of our employees.

Performance reviews are completed annually to ensure a focus on development of employees along with an assessment of performance and potential, which supports succession planning and informs development efforts across the company to ensure we are continuing to build a deep bench of talent within Radian.

Community Involvement

We understand the value of investing in the communities in which our employees live and work, which is why we continue to strengthen and grow our Corporate Citizenship Program. Since its inception, the program – through both company and employee contributions – has provided significant financial support to charities across the country. The program consists of three pillars: charitable contributions, matching gifts and community connection.

Charitable contributions include donations made by Radian to non-profit organizations, including direct corporate contributions and sponsorship of charitable events. In 2023, we provided financial support to community organizations through direct giving, sponsorships, and fundraisers. This includes our multi-year commitment to support the Mortgage Banker Association’s Opens Doors Foundation. Our matching gifts program includes a charitable contribution made by Radian to non-profit organizations that reflect a donation made by an employee. To strengthen our matching gifts program and continue encouraging the generosity of employees, we launched a Workplace Giving Platform to make giving easier than ever by eliminating the previous multi-step process.

Our community-based program, Radian Connected, provides opportunities for employee engagement and community involvement, including volunteerism and opportunities for learning and skill development, as well as social opportunities to network and build stronger working relationships. We understand the causes employees spend time supporting are near and dear to their hearts, which is why we introduced Dollars-for-Doers, a grant program that recognizes the time employees spend giving back to their communities by giving a charitable gift to the nonprofit of the employee’s choice after they complete 40 hours of service. This program reflects our commitment to making a difference in communities where our employees live and work, and also helps in our efforts to attract and retain employees.

Regulation

We are subject to comprehensive regulation by both federal and state regulatory authorities. Set forth below is a description of significant state and federal regulations as well as requirements of the GSEs that are applicable to our businesses. The descriptions below are summaries only and are qualified in their entirety by reference to the full text of the laws and regulations discussed. In “Item 1A. Risk Factors,” see “Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy” and “Legislation and administrative and regulatory changes and interpretations could impact our businesses.”

State Regulation

Overview of State Insurance Regulation and Our Insurance Subsidiaries

We and our insurance subsidiaries are subject to comprehensive regulation by the insurance departments in the various states where they are licensed to transact business. Insurance laws vary from state to state, but generally grant broad supervisory powers to agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business. These regulations principally are designed for the protection of policyholders, rather than for the benefit of investors.

Insurance regulations address, among other things, the licensing of companies to transact business, claims handling, credit for reinsurance, premium rates and policy forms, sales and marketing activity, financial statements, periodic reporting, permissible investments and adherence to financial standards relating to surplus, dividends and other measures of solvency intended to assure the satisfaction of obligations to policyholders.

Our insurance subsidiaries’ premium rates and policy forms are generally subject to regulation in every state in which they are licensed to transact business. These regulations are intended to protect policyholders against excessive, inadequate or unfairly discriminatory rates and to encourage competition in the insurance marketplace. In most states where our insurance subsidiaries are licensed, premium rates and policy forms must be filed with the state insurance regulatory authority and, in some states, must also be approved before their use.

With respect to mortgage insurance, premium rates may be subject to actuarial justification, generally on the basis of the mortgage insurer’s loss experience, expenses and future projections. In addition, state regulators may assess how rates are being charged to various customers based on whether they are “similarly situated” to other customers, and state regulators also may evaluate general default experience in the mortgage insurance industry in assessing the premium rates charged by mortgage insurers. In many states, the filed forms allow for a deviation from the filed rates within a certain range to take into consideration various factors linked to the risk being insured.

As to title insurance, premium rates and policy forms must be filed with state insurance regulatory authorities and, in some states, must also be approved before their use. Policy forms require approval to ensure that the coverage and exceptions conform to state insurance regulations. Premium rates subject to approval often must be supported by actuarial data or a study of the financial impact of the premium rate on the insurer. States also impose restrictions on title sales and marketing activity, either through regulations that are specific to title marketing or through broader state insurance licensing, anti-inducement and anti-rebating laws.

Each insurance subsidiary is required by the insurance regulatory authority of its state of domicile, and the insurance regulatory authority of each other jurisdiction in which it is licensed to transact business, to make various filings with those authorities and with the NAIC, including quarterly and annual financial statements prepared in accordance with SAP. In addition, our insurance subsidiaries are subject to examination by the insurance regulatory authority of their state of domicile, as well as each of the states in which they are licensed to transact business.

Radian Group is an insurance holding company, and Radian Group’s subsidiaries, including our mortgage insurance subsidiaries and title insurance company, belong to an insurance holding company system. We are subject to the insurance holding company laws of Pennsylvania and Ohio because all of our mortgage insurance subsidiaries are domiciled in Pennsylvania and Radian Title Insurance is domiciled in Ohio. These insurance holding company laws regulate, among other things, certain transactions between Radian Group, our insurance subsidiaries and affiliates.

The holding company laws of Pennsylvania and Ohio also govern certain transactions involving Radian Group’s common stock, including transactions that constitute a “change of control” of Radian Group and, consequently, a “change of control” of its insurance subsidiaries. Specifically, no person may, directly or indirectly, seek to acquire “control” of Radian Group or any of its insurance subsidiaries unless that person received prior approval after filing a statement and other documents with the Pennsylvania Insurance Department or Ohio Department of Insurance for a change in control of any of our mortgage insurance subsidiaries or Radian Title Insurance, respectively, and with both the Pennsylvania Insurance Department and Ohio Department of Insurance for a change in control involving Radian Group. Under Pennsylvania’s and Ohio’s insurance statutes, “control” is defined broadly. For instance, Pennsylvania’s statute provides that control is “presumed to exist if any person, directly or indirectly, owns, controls, holds with power to vote or holds proxies representing 10% or more” of the votes that all shareholders would be entitled to cast in the election of directors. For both Pennsylvania and Ohio, the statutes further define

32

Part I. Item 1. Business

“control” as the “possession, direct or indirect, of the power to direct or cause the direction of the management and policies of” an insurer.

In addition, transactions between any one of our insurance subsidiaries and any Radian-affiliated entity are subject to certain conditions, including that they be “fair and reasonable.” These conditions generally apply to all persons controlling, or who are under common control with, Radian Group and its insurance subsidiaries. Certain transactions between our insurance subsidiaries and a Radian-affiliated entity may not be entered into unless the Pennsylvania Insurance Department or Ohio Department of Insurance, as applicable, is given 30 days’ prior notice and does not disapprove the transaction during that 30-day period.

Radian Guaranty is authorized to write insurance in all 50 states, the District of Columbia and Guam as a monoline insurer, and is restricted by the laws of certain states to writing first-lien residential mortgage guaranty insurance (or in states where there is no specific authorization for mortgage guaranty insurance, the applicable line of insurance under which mortgage guaranty insurance is regulated). Radian Guaranty is our only mortgage insurance company that is currently eligible to provide first-loss mortgage insurance on GSE loans.

We also have the following mortgage insurance subsidiaries: Radian Insurance, a direct wholly owned subsidiary of Radian Group that is licensed in Pennsylvania and insures a small amount of second-lien mortgage loan risk written prior to the great financial crisis in 2008; and Radian Mortgage Assurance, a direct wholly owned subsidiary of Radian Group that has a license or its equivalent in all 50 states and the District of Columbia, but which had no RIF as of December 31, 2023.

As part of our title services business, we offer title insurance through Radian Title Insurance. Radian Title Insurance is an Ohio domiciled title insurance underwriter and settlement services company that is licensed to issue title insurance policies in 41 states and the District of Columbia. Radian Title Insurance is an indirect subsidiary of Radian Group and is wholly owned by Radian Title Services Inc.

Mortgage Insurance Capital Requirements and Dividends

Under state insurance regulations, Radian Guaranty is required to maintain minimum surplus levels and, in certain states, a Statutory RBC Requirement that is based on a maximum ratio of net RIF relative to statutory capital, or Risk-to-capital. The most common Statutory RBC Requirement is that a mortgage insurer’s Risk-to-capital may not exceed 25 to 1, while in certain other RBC States, Radian Guaranty must satisfy a MPP Requirement. As of December 31, 2023, Radian Guaranty’s Risk-to-capital was 10.4 to 1, and Radian Guaranty was in compliance with all applicable Statutory RBC Requirements. See Note 16 of Notes to Consolidated Financial Statements for more information on statutory capital requirements, including the NAIC’s recent approval in August 2023 of an amended Model Act for mortgage insurers that could be adopted through legislation in one or more states, and regardless of adoption, also could serve as the basis for how the NAIC updates the SAPs applicable to mortgage insurers. In “Item 1A. Risk Factors,” see “Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy.”

Mortgage insurance companies are required annually to set aside contingency reserves in their statutory financial statements in an amount equal to 50% of earned premiums. The contingency reserve, which is designed to be a reserve against catastrophic losses, essentially has the effect of restricting dividends and other ordinary distributions by mortgage insurance companies as amounts set aside for contingency reserves cannot be released into unassigned surplus for a period of 10 years, except when loss ratios exceed 35% of the corresponding earned premiums, in which case the amount above 35% can be released under certain circumstances.

Under Pennsylvania’s insurance laws, dividends and other ordinary distributions may only be paid out of an insurer’s positive unassigned surplus unless the Pennsylvania Insurance Department approves the payment of dividends or other distributions from another source. While all proposed dividends and distributions to stockholders must be filed with the Pennsylvania Department of Insurance prior to payment, if a Pennsylvania domiciled insurer has positive unassigned surplus, such insurer can pay dividends or other distributions during any 12-month period in an aggregate amount less than or equal to the greater of: (i) 10% of the preceding year-end statutory policyholders’ surplus or (ii) the preceding year’s statutory net income, in each case without the prior approval of the Pennsylvania Insurance Department.

Aided by the positive impacts of the merger with Radian Reinsurance in December 2022, Radian Guaranty had positive unassigned surplus of $258 million as of December 31, 2022, and continued to maintain positive unassigned surplus throughout 2023. As a result, beginning with the first quarter of 2023, Radian Guaranty had the ability to pay ordinary dividends, and paid total ordinary dividends of $400 million in cash and marketable securities in 2023. Subsequent to the payment of these dividends, as of December 31, 2023, Radian Guaranty had positive unassigned surplus of $120 million, and in February 2024, Radian Guaranty paid an ordinary dividend of $100 million in cash and marketable securities to Radian Group. Radian Guaranty expects to have the ability to continue paying ordinary dividends in 2024. Based on the typical 10-year holding requirement, Radian Guaranty is scheduled to release contingency reserves to unassigned surplus in material amounts beginning in 2024, which will aid Radian Guaranty’s capacity to pay ordinary dividends in 2024. See Note 16 of Notes to Consolidated Financial Statements for additional information on contingency reserve requirements and statutory dividend restrictions.

33

Part I. Item 1. Business

Title Insurance Capital Requirements and Dividends

Radian Title Insurance is required to maintain Statutory Premium Reserves (“SPR”), calculated as a percentage of gross premiums collected. The SPR requirements are set by each state, with the most common being 7% of gross premiums collected. The SPR is then recovered based on a release schedule, amortized over 20 years. In addition to the SPR, Radian Title Insurance is subject to periodic reviews of certain financial performance ratios by the regulators in the states in which it is licensed, and these regulators can impose capital requirements on Radian Title Insurance based on the results of those ratios.

Under Ohio’s insurance laws, dividends and other ordinary distributions may only be paid out of an insurer’s positive unassigned surplus unless the Ohio Department of Insurance approves the payment of dividends or other ordinary distributions from another source. While all proposed dividends and distributions to stockholders must be filed with the Ohio Department of Insurance prior to payment, if an Ohio domiciled insurer had positive unassigned surplus, such insurer can pay dividends or other distributions during any 12-month period in an aggregate amount less than or equal to the greater of: (i) 10% of the preceding year-end statutory policyholders’ surplus or (ii) the preceding year’s statutory net income, in each case without the prior approval of the Ohio Department of Insurance. Radian Title Insurance had negative unassigned surplus of $9 million and $11 million at December 31, 2023 and 2022, respectively, and therefore was unable to pay ordinary dividends in 2023 and is currently unable to pay dividends or other ordinary distributions in 2024 without prior approval from the Ohio Department of Insurance.

Other Businesses

In addition to our insurance subsidiaries, certain of our other subsidiaries are subject to regulation and oversight by the states in which they conduct their businesses, including requirements to be licensed and/or registered in these states.

Our real estate brokerage business conducted through homegenius Real Estate provides services in all 50 states and the District of Columbia. This entity, together with its agents, is required to hold licenses and conduct the brokerage business in conformity with the applicable license laws and administrative regulations of the states in which they are conducting their business. As a licensed real estate brokerage, homegenius Real Estate receives residential real estate data from various multiple listing services (“MLS”) through agreements with these MLS providers, which it uses to broker real estate transactions and provide valuation products and services, pursuant to the terms of these agreements. These MLS agreements include restrictions on the permitted use of the MLS data obtained through these agreements and impose requirements on the business of real estate brokerages in order to maintain eligibility to continue to receive the MLS data. If these agreements were to be terminated or homegenius Real Estate otherwise were to lose access to this data, it could negatively impact homegenius Real Estate’s ability to conduct its business.

Radian Mortgage Capital is a mortgage conduit that is licensed to purchase, hold and sell residential mortgages in 49 states and the District of Columbia. Radian Mortgage Capital acquires and aggregates residential mortgage loans and then sells the loans directly to mortgage investors. Subject to market conditions, Radian Mortgage Capital also expects to distribute the loans into the capital markets through private label securitizations in the future. Radian Mortgage Capital is the master servicer for the loans it acquires and has engaged a subservicer to manage the day-to-day servicing operations for its acquired mortgage loan portfolio. The subservicer is subject to Radian Mortgage Capital’s compliance oversight, which includes quality control reviews of services provided to ensure compliance with applicable state and federal laws. In “Item 1A. Risk Factors,” see “Investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business subject us to additional risks and uncertainties.”

Radian Lender Services LLC provides third-party mortgage underwriting and has also provided mortgage processing services to lenders. This entity and its employees who provide these services are required to be in compliance with the SAFE Act in all jurisdictions where these services are provided. The entity and its employees are SAFE Act compliant for underwriting in all 50 states and the District of Columbia and for loan processing in 45 states and the District of Columbia. See “Federal Regulation—The SAFE Act” below.

Radian Settlement Services and its subsidiaries provide title and escrow services, and these entities are required to hold licenses in the jurisdictions where they operate their business. Title insurance agency and escrow licensing is primarily regulated by states in which the services are being offered, with licensing and registration typically conducted under the jurisdiction of each state’s department of insurance. Radian Settlement Services is domiciled and licensed in Pennsylvania as a resident title insurance agency and, together with its subsidiaries, is licensed in 42 states and the District of Columbia.

Radian Valuation Services LLC is an appraisal management company, licensed in all 50 states and the District of Columbia, that supports certain valuation services provided by homegenius Real Estate. Real estate appraisal management statutes and regulations vary from state to state, but generally grant broad supervisory powers to agencies or officials to examine companies and enforce rules. While these businesses are generally state regulated, the Dodd-Frank Act established minimum requirements to be implemented by states regarding the registration and supervision of appraisal management companies. Most states have based their legislation on model legislation developed by the Appraisal Institute for the registration and oversight of appraisal management companies.

Information Security

The NYDFS has adopted cybersecurity regulations known as “Part 500” that apply to all financial institutions and insurance companies licensed under the New York Banking, Insurance, and Financial Services Laws, including Radian Guaranty and certain of our other subsidiaries. The regulations, which recently were amended in November 2023, require covered entities to, among other things: establish a cybersecurity program; adopt a written cybersecurity policy; designate a Chief Information Security Officer responsible for implementing, overseeing and enforcing the cybersecurity program and policy; and have policies and procedures designed to ensure the security of information systems and nonpublic information accessible to, or held by, third parties, along with a variety of other requirements to protect the confidentiality, integrity and availability of information systems. The November 2023 amendments to Part 500 include enhanced governance requirements, stricter access and privilege controls, and additional notification, reporting and other requirements. A number of the requirements included as part of the November 2023 amendments are subject to staggered transitional periods over the next two years.

In 2017, the NAIC issued an Insurance Data Security Model Law, which was modelled after Part 500, and which several states have adopted. The stated intention of that model law is that if a covered insurance company is compliant with Part 500, it also would be in compliance with the NAIC Insurance Data Security Model Law, although states that adopt the Data Security Model Law can impose their own unique requirements.

Privacy

The State of California has adopted the California Consumer Privacy Act (“CCPA”) that applies to any company that does business in California and meets certain threshold requirements. We believe Radian Group and certain of its affiliates, including Radian Guaranty, may be deemed covered businesses under the CCPA.

The CCPA imposes a privacy framework for covered businesses that collect, sell or disclose personal information of California residents. Companies subject to the CCPA are required to establish procedures to enable them to comply with a California resident’s data privacy rights, including by disclosing the privacy practices of the entity and responding to verified requests within prescribed timeframes. The CCPA provides a private right of action for data breaches, including statutory or actual damages, and public enforcement by the California Attorney General for other violations.

On January 1, 2023, California adopted the California Privacy Rights Act (“CPRA”), which amended the CCPA to enhance certain of the privacy protections for California residents that were created by the CCPA. The enhancements include imposing additional compliance obligations for covered entities and removing certain exemptions previously available under the CCPA. While the California Attorney General retains civil enforcement authority, the CPRA also created the California Privacy Protection Agency to implement and enforce the law. Other states, including Colorado, Connecticut, Delaware, Indiana, Iowa, Montana, New Jersey, Oregon, Tennessee, Texas, Utah and Virginia, have recently passed consumer privacy laws that are similar to the CCPA and afford residents of those states a number of data privacy rights. Additionally, many states have enacted privacy and information practices laws that apply to insurance companies.

We have policies and procedures in place to comply with the CCPA and other currently applicable state privacy laws. In addition, several other states have also proposed new privacy laws, and federal regulators have proposed draft federal privacy legislation, all of which, to the extent they are adopted, could impose additional compliance obligations on covered entities beyond those currently in effect and could impact our businesses or those of our customers.

Federal Regulation

CARES Act and GSE COVID-19 Forbearance

Following the outbreak of the COVID-19 pandemic, there were a number of governmental efforts to implement programs designed to assist individuals and businesses impacted by the COVID-19 virus, including the CARES Act that was enacted by the federal government on March 27, 2020.

Under the CARES Act, upon request by borrowers of federally backed mortgage loans who attested to financial hardship related to the pandemic, including with respect to loans purchased by the GSEs, mortgage servicers were required to provide these borrowers with up to 180 days forbearance on their mortgage payments (which could be extended for an additional 180 days upon request) without requiring the servicer to evaluate the borrower’s hardship. The GSEs adopted temporary changes to their servicing policies to incorporate COVID-19-related forbearance plan flexibilities and other alternatives to support borrowers impacted by the COVID-19 pandemic.

In November 2023, the GSEs began the phased retirement of their servicing policies related to COVID-19, including discontinuing new enrollments of COVID-19-related forbearance plans provided in accordance with the CARES Act and reverting to the policies as specified in their servicing guides. This means that simply attesting to a financial hardship due to COVID-19 is no longer an eligible hardship for borrowers seeking forbearance under the GSEs’ servicing policies. However, borrowers with other short-term hardships continue to have access to the GSEs’ loss mitigation programs, including forbearance and payment deferrals. For borrowers on COVID-19-related forbearance plans prior to November 1, 2023, their

35

Part I. Item 1. Business

forbearance plans remain in place in accordance with the terms of the forbearance agreement and existing GSE COVID-19-related servicing requirements.

The American Rescue Plan Act of 2021 authorizes approximately $9.9 billion to fund a Homeowner Assistance Fund for “the purpose of preventing homeowner mortgage delinquencies, defaults, foreclosures, loss of utilities or home energy services, and displacements of homeowners experiencing financial hardship after January 21, 2020.” Since the enactment of this legislation, Treasury has issued guidance on this program and announced allocations by state, with a statutory minimum requirement of $50 million for each state, the District of Columbia and Puerto Rico. According to the guidance issued by Treasury, eligible use of these funds may include mortgage payment assistance, assistance for housing-related costs related to a period of forbearance, delinquency, or default, facilitating mortgage interest reductions, and assistance with insurance payments, including mortgage insurance, utility and tax payments, among others.

GSE Requirements for Mortgage Insurance Eligibility

As the largest purchasers of conventional mortgage loans, and therefore the main beneficiaries of private mortgage insurance, the GSEs impose eligibility requirements that private mortgage insurers must satisfy in order to be approved to insure loans purchased by the GSEs. The PMIERs aim to ensure that approved insurers will possess the financial and operational capacity to serve as strong counterparties to the GSEs throughout various market conditions. The PMIERs are comprehensive, covering virtually all aspects of the business and operations of a private mortgage insurer of GSE loans, including internal risk management and quality controls, the relationship between the GSEs and the approved insurer and the approved insurer’s financial condition. The PMIERs contain extensive requirements related to the conduct and operations of our mortgage insurance business, including operational requirements in areas such as claim processing, loss mitigation, document retention, underwriting, quality control, reporting and monitoring, among others. Radian Guaranty currently is an approved mortgage insurer under the PMIERs. The GSEs have significant discretion under the PMIERs, which they may amend at any time. The most recent large-scale revisions to the PMIERs became effective on March 31, 2019, and the GSEs frequently evaluate the PMIERs for interim changes to address various specific matters. We expect the GSEs to continue to update the PMIERs in the future as they may deem necessary.

The PMIERs’ financial requirements require that a mortgage insurer’s Available Assets meet or exceed its Minimum Required Assets. The PMIERs’ financial requirements include increased financial requirements for defaulted loans (as further discussed below), as well as for performing loans with a higher likelihood of default and/or certain credit characteristics, such as higher LTVs or lower FICO credit scores. In addition, the current PMIERs financial requirements also impose limitations on the credit that is granted for certain Available Assets. The PMIERs also prohibit Radian Guaranty from engaging in certain activities such as insuring loans originated or serviced by an affiliate (except under certain circumstances) and require Radian Guaranty to obtain the prior consent of the GSEs before taking many actions, which may include, among other things, entering into various intercompany agreements, settling loss mitigation disputes with customers and commuting risk.

With respect to defaulted loans, the PMIERs recognize that loans that have become non-performing as a result of a FEMA Declared Major Disaster eligible for individual assistance (e.g., due to a natural disaster) generally have a higher likelihood of curing following the conclusion of the event, and therefore apply a Disaster Related Capital Charge for a period of time and subject to certain limitations, to reduce the Minimum Required Asset factor for these loans. Under the PMIERS, for defaulted loans located in a FEMA Declared Major Disaster area that either (1) are subject to a forbearance plan granted in response to the disaster (with terms consistent with forbearance plans offered by the GSEs) or (2) have an initial missed monthly payment occurring 30 days prior to the first day of the incident period specified in the Major Disaster Declaration or 90 days following the last day of the incident period specified in the Major Disaster Declaration (not to exceed 180 days from the first day of the incident period), the Disaster Related Capital Charge will be applied for the longer of three calendar months beginning with the month when the loan became a defaulted loan or the period of time that the defaulted loan remains subject to a forbearance plan granted in response to the disaster.

In 2020, in response to the COVID-19 pandemic, the GSEs issued guidelines (“National Emergency Guidelines”) that became effective June 30, 2020, and, among other things, adopted the COVID-19 Amendment to the PMIERs to apply the Disaster Related Capital Charge nationwide to certain non-performing loans that we refer to as COVID-19 Defaulted Loans. Under the COVID-19 Amendment, the Disaster Related Capital Charge is applied to COVID-19 Defaulted Loans for the period of time that the loan is subject to a forbearance plan, repayment plan or loan modification trial period granted in response to a financial hardship related to COVID-19. In the periods following the onset of the COVID-19 pandemic, the Disaster Related Capital Charge related to COVID-19 Defaulted Loans significantly reduced Radian’s Minimum Required Assets. This benefit has diminished materially over time as the number of COVID-19 Defaulted Loans has been reduced, primarily as a result of these defaults curing. Given the retirement of the GSEs’ COVID-19-related servicing policies and the limited benefit resulting from the Disaster Related Capital Charge being applied to COVID-19 Defaulted Loans, we expect that this Disaster Related Capital Charge for COVID-19 Defaulted Loans will be terminated in the future.

As part of our capital and risk management activities, including to manage Radian Guaranty’s capital position under the PMIERs financial requirements, we have distributed risk through third-party quota share and excess-of-loss reinsurance arrangements, including through the capital markets using mortgage insurance-linked notes transactions. The initial and ongoing credit that we receive under the PMIERs financial requirements for these risk distribution transactions is subject to the

36

Part I. Item 1. Business

periodic review of the GSEs and could be influenced by the capital requirements for the GSEs set forth in the ERCF, which, among other things, provides the GSEs with a reduced amount of credit for their own credit risk transfer activities.

See “Housing Finance Reform and the GSEs’ Business Practices” below for additional information that could impact the PMIERs. In “Item 1A. Risk Factors,” see “Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity” and “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

GSE Requirements for Selling Loans to the GSEs

Radian Mortgage Capital is also required to maintain specified levels of capital and meet various operational requirements and standards to be approved to sell loans to the GSEs and service such loans on their behalf. The capital requirements are generally tied to the unpaid balances of loans included in Radian Mortgage Capital’s servicing portfolio or loan production volume. Noncompliance with these requirements can result in various remedial actions up to, and including, the applicable GSE’s revocation of Radian Mortgage Capital’s ability to sell loans to and service loans on its behalf. Radian Mortgage Capital is currently approved to sell loans to and service loans on behalf of Freddie Mac.

Housing Finance Reform and the GSEs’ Business Practices

Legislative Reform

The federal government plays a significant role in the U.S. housing finance system through, among other things, the involvement of the FHFA and GSEs, HUD, the FHA and the VA. The GSEs’ charters, which can only be altered by federal legislation, generally prohibit them from buying low down payment mortgage loans without certain forms of credit enhancement, the most common form of which has been private mortgage insurance.

Since the FHFA was appointed as conservator of the GSEs in September 2008, there have been a wide range of legislative proposals to reform the U.S. housing finance market, including proposals for GSE reform. While many legislative proposals have been debated and occasionally advanced through various legislative procedures, no reform proposal has reached an advanced legislative stage. As a consequence, most reform-related actions with respect to the housing finance system have occurred administratively through regulatory actions.

Administrative Reform

The executive branch of the government (the “Administration”), typically through its departments and regulatory agencies, offers perspectives on the future of housing finance in the U.S., including objectives for future strategic direction and areas of focus. As a result, a change in Administrations can significantly alter the strategic direction of housing finance in the U.S.

Although many departments or agencies impact housing finance in some manner, the most prominent and directly impactful are the FHFA, HUD, the U.S. Department of the Treasury (“Treasury”) and the CFPB. In June 2021, following a Supreme Court decision that determined that the FHFA director may be removed by the President other than for cause, President Biden removed the FHFA director appointed by President Trump and appointed Sandra Thompson. Under Director Thompson, the FHFA has been focused on increasing the equitable accessibility and affordability of mortgage credit, in particular to low- and moderate-income borrowers and underserved communities, while also continuing to ensure the safety and soundness of the GSEs. The Supreme Court’s decision providing that the FHFA director may be removed by the President without cause creates a higher likelihood that the direction of the FHFA and its oversight over the GSEs may be impacted by elections and the political leanings of the Administration in office at the time.

Senior Preferred Stock Purchase Agreements. The Treasury currently owns the preferred stock of the GSEs pursuant to the terms of Senior Preferred Stock Purchase Agreements (“PSPAs”), and therefore, has significant influence over the fate and direction of the GSEs. In January 2021, the PSPAs were amended to allow the GSEs to continue to retain capital up to the amounts prescribed in the GSE capital requirements set forth in the ERCF, as discussed below.

The January 2021 PSPA amendment to the PSPAs restricted the GSEs’ acquisition of higher-risk single-family mortgage loans, including in particular the acquisition of investor loans and single-family mortgage loans with two or more higher risk characteristics (i.e., LTVs greater than 90%, debt-to-income ratios greater than 45% and FICO credit scores less than 680), to their then current levels. The January 2021 PSPA amendment further restricted the quality of loans that may be purchased by the GSEs by limiting the GSEs’ purchases to, among other enumerated types, loans that meet the QM definition. In September 2021, Treasury and the FHFA agreed to suspend the limitations on GSE purchases of loans deemed higher risk that were set forth in the January 2021 amendments to the PSPAs.

Enterprise Regulatory Capital Framework and Liquidity Requirements. In 2020, the FHFA adopted the ERCF for the purpose of developing capital and liquidity requirements for the GSEs. Since finalizing this rule, the FHFA has adopted several amendments to the ERCF, most recently by a rule adopted in November 2023. As compared to the capital requirements for the GSEs in place prior to the ERCF, the ERCF, as amended: (i) significantly increased such capital requirements and (ii) decreased the capital credit provided to the GSEs for credit risk transfer transactions. In addition, the FHFA has proposed new

37

Part I. Item 1. Business

minimum liquidity requirements for the GSEs, which have not been finalized. The ERCF and the proposed new liquidity requirements could significantly alter the business practices and operations of the GSEs which could have a material effect on the conventional mortgage market and our business with the GSEs, and could result in changes to the PMIERs.

In “Item 1A. Risk Factors,” see “Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity” and “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

Access and Affordability. The Biden Administration’s housing plan focuses on: (i) increasing access to sustainable homeownership and making housing more affordable for low- and moderate-income borrowers; (ii) ensuring the housing finance system is equitable by identifying and eliminating discriminatory or unfair practices in the housing system; (iii) increasing the supply, lowering the cost and improving the quality of housing, including through investments in resilience, energy efficiency, and accessibility of homes; and (iv) providing financial assistance to help Americans buy or rent safe, quality housing, including down payment assistance.

Since assuming leadership over the FHFA in June 2021, the Biden-appointed FHFA leadership team has instituted changes to further advance mortgage access and affordability. In June 2022, the FHFA announced the release of the GSEs’ Equitable Housing Finance Plans, providing a framework for planned initiatives to address equity in housing finance. Since then, the FHFA has released annual updates to these plans that include various initiatives to be conducted over a three-year period that aim to address barriers to homeownership for minority and underserved communities. In accordance with their plans, Fannie Mae and Freddie Mac have launched their own Special Purpose Credit Programs (“SPCPs”) and worked with lenders to purchase loans originated through lender SPCPs. While future changes to these programs remain uncertain, modifications to these programs could include changes to mortgage insurance requirements, such as the required mortgage insurance coverage percentage. The plans also include expected activity to address alternative credit and data in underwriting, property appraisals and other valuations, and title insurance, among other items.

Radian Guaranty and other private mortgage insurance companies have been engaged in discussions with the GSEs regarding how the industry may support the GSEs to advance these objectives. Depending on the outcome of such dialogue, one or both of the GSEs, together or in conjunction with one or more private mortgage insurers, could implement further initiatives in pursuit of housing policy objectives that could require changes to the GSEs’ business practices and impact our businesses.

In October 2022, the FHFA announced that the GSEs will replace their use of Classic FICO credit scores with FICO 10T and VantageScore 4.0 credit scores, which are intended to improve accuracy by capturing additional payment histories for borrowers when available, such as rent, utilities, and telecom payments. The GSEs will require both of the new credit scores, along with credit reports from two, rather than three, of the credit reporting agencies. The implementation timeline for the transition to the new credit scores is expected to be a multi-year effort. The FHFA has released a proposed timeline for implementing the changes that is expected to occur over two phases in 2024 and 2025. As a mortgage insurer, credit scores are utilized in several areas of Radian Guaranty’s operations and adoption of the new credit scores will require planning and analysis to, among other things, understand how these scores calibrate to Radian Guaranty’s credit risk models. In addition, the transition to the new credit scores and the reduction to two instead of three credit reports is expected to result in changes to Radian Guaranty’s underwriting guidelines.

Also in October 2022, the FHFA announced, among other pricing changes, an elimination of GSE loan-level pricing adjustments (upfront fees) for some first-time and low- and moderate-income borrowers, including first-time homebuyers at or below 100% of area median income (“AMI”) in most of the United States and below 120% of AMI in high-cost areas. In January 2023, the FHFA announced additional pricing changes for the GSEs based on certain loan characteristics. These changes were effective in May 2023, with the exception of planned pricing changes for loans with debt-to-income ratios above 40%, which were subsequently rescinded.

In “Item 1A. Risk Factors,” see “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

New Products. In December 2022, the FHFA released a final rule regarding the process for how it will consider and approve new GSE activities and products. Among other things, the rule redefines the criteria for determining what constitutes a new activity that requires prior notice to the FHFA and for determining whether the activity constitutes a “new product” that requires public notice and comment. The final rule provides increased transparency by requiring the FHFA to publish the outcome of their review of new product and activity submissions by the GSEs. Given the size and market influence of the GSEs, this new rule is generally viewed as important to ensure that the GSEs, as is specified in their charters, are not otherwise encroaching on areas that may be more appropriately served by private capital.

It is difficult to predict what types of new products and activities may be proposed by the GSEs in the future and, if applicable, whether they may be approved by the FHFA, including programs that may provide an alternative to traditional private mortgage insurance or title insurance. For example, if any existing or future credit risk transfer transactions and structures were to displace primary loan level or standard levels of mortgage insurance, the amount of mortgage insurance we write may be reduced, which could negatively impact our franchise value, results of operations and financial condition. In “Item

38

Part I. Item 1. Business

1A. Risk Factors,” see “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

Climate Change. The FHFA has instructed the GSEs to designate climate change as a priority concern and actively consider its effects in their decision making. In 2022, the FHFA established internal working groups and a steering committee in order to monitor the GSEs’ management of climate risk. It is possible that efforts to manage these risks by the FHFA and the GSEs (including through GSE guideline or mortgage insurance policy changes) could materially impact the volume and characteristics of our NIW (including the terms of our Master Policy), home prices in certain areas and defaults by borrowers in certain areas.

HUD/FHA/VA

Private mortgage insurance competes for a share of the insurable mortgage market with the single-family mortgage insurance programs of the FHA, including on the basis of loan limits, pricing, credit guidelines, terms of insurance policies and loss mitigation practices. To a lesser extent, private mortgage insurance also competes with the loan insurance programs of the Department of Veteran Affairs, although almost all of VA insured loans are issued without down payment, and therefore, would be ineligible for private mortgage insurance.

While the FHA continues to insure a significant portion of the total low down payment mortgage market, with respect to the portion of the market where private mortgage insurance and the FHA’s products compete, the private mortgage insurance industry has been competing effectively with FHA execution.

As discussed above, the Biden Administration has been pursuing actions that will further its stated objective of increasing access to affordable mortgages for low- and moderate-income borrowers. In this regard, in March 2023, the FHA reduced its annual mortgage insurance premium by 0.30% for most new borrowers. While this pricing change has not had a material impact on our business volumes, the FHA could institute further pricing changes in the future, including additional changes to its annual premiums, a reduction in its upfront premiums and/or the elimination of the life-of-loan premium requirement for FHA insured loans. The potential for future pricing changes could be influenced by the financial strength of the FHA’s Mutual Mortgage Insurance (“MMI”) Fund. As last reported in November 2023, the FHA’s MMI Fund had a combined capital ratio for fiscal year 2023 of 10.51%, above the 2% ratio that the FHA is required to maintain. It is uncertain if and when the FHA may pursue any additional pricing or other actions and what form they may take; however, any change that would improve FHA execution compared to execution through the GSEs with private mortgage insurance could negatively impact our NIW volume.

The Dodd-Frank Act

The Dodd-Frank Act mandates significant rulemaking by several regulatory agencies to implement its provisions. The Dodd-Frank Act established the CFPB to regulate the offering and provision of consumer financial products and services under federal law, including residential mortgages and settlement services, and transferred authority to the CFPB to enforce many existing consumer-related federal laws, including the Truth in Lending Act, RESPA and prohibitions on Unfair, Deceptive, or Abusive Acts or Practices. A number of these laws apply to products and services provided by us and our affiliates.

Qualified Mortgage Requirements—Ability to Repay Requirements

Among the most significant provisions for private mortgage insurers under the Dodd-Frank Act are the ability to repay mortgage provisions (“Ability to Repay Rule”), including a related safe harbor set forth in the QM Rule (defined below).

The Ability to Repay Rule requires mortgage lenders to make a reasonable and good faith determination that, at the time a loan is consummated, the consumer has a reasonable ability to repay the loan. The Dodd-Frank Act provides that a creditor may presume that a borrower will be able to repay a loan if the loan has certain low-risk characteristics that meet the definition of a qualified mortgage, or QM (“QM Rule”). This QM presumption is generally rebuttable, however, loans that are deemed to have the lowest risk profiles are granted a safe harbor from liability (“QM Safe Harbor”) related to the borrower’s ability to repay the loan.

In December 2020, the CFPB finalized two new definitions of QM. One of these new QM definitions (the “New General QM Definition”) adopts a pricing-based approach to QM. Under the New General QM Definition, certain underwriting considerations are retained, but QM status generally is achieved if the loan is priced at no greater than 2.25% above the Average Prime Offer Rate (“APOR”). Loans priced at or less than 1.5% above APOR are subject to the QM Safe Harbor, while all other QM loans would receive the general rebuttable presumption that the loans met the ability to repay standard.

Separately, the CFPB created another new QM definition (“Seasoned QM”) for first-lien, fixed-rate loans that meet certain performance requirements over a 36-month seasoning period and are held in the lender’s portfolio until the end of the seasoning period. After a transition period in which both the original and new QM definitions were applicable, both new QM definitions replaced the original QM definition on October 1, 2022.

The QM Rule requires that points and fees paid at or prior to closing cannot exceed 3% of the total loan amount, with higher points and fees thresholds provided for loan amounts below a certain threshold. Any private mortgage insurance premiums paid by the borrower at or before the time of loan closing (other than monthly or annual premiums) must be applied toward the 3% points and fee calculation with the exception of premiums that are automatically refundable on a pro-rata basis

39

Part I. Item 1. Business

upon loan satisfaction, in which case only the amount that exceeds the FHA upfront mortgage insurance premium must be included in the points and fees calculation. There are no similar restrictions on the points and fees associated with FHA premium, and thus FHA may have a market advantage when the upfront private mortgage insurance premium is not refundable on a pro-rata basis or exceeds the FHA upfront mortgage insurance premium.

The Dodd-Frank Act also granted the FHA, VA and USDA flexibility to establish their own QM definitions for their insurance guaranty programs. Both the FHA and VA have created their own definitions of qualified mortgages that differ from both the CFPB’s original QM Definition and New General QM Definition. For example, the FHA’s QM Safe Harbor definition currently applies to loans priced at or less than APOR plus the sum of 1.15% and the FHA’s annual mortgage insurance premium rate, which is effectively broader than the QM Safe Harbor adopted under the New General QM Definition. These alternate definitions of qualified mortgages are more favorable to lenders and mortgage holders than the CFPB’s New General QM Definition that apply to loans purchased by the GSEs, and could provide for more favorable execution for FHA insured loans compared to loans insured with private mortgage insurance.

For more information regarding the New General QM Definition and the risks it may present for us, in “Item 1A. Risk Factors,” see “A decrease in the volume of mortgage originations could result in fewer opportunities for us to write new mortgage insurance business and conduct our homegenius businesses.”

Qualified Residential Mortgage Regulations—Securitization Risk Retention Requirements

The Dodd-Frank Act requires securitizers to retain at least 5% of the credit risk associated with mortgage loans that they transfer, sell or convey, unless the mortgage loans are qualified residential mortgages (“QRMs”) or are insured by the FHA, another federal agency or are backed by the GSEs while in conservatorship (the “QRM Rule”). Under applicable federal regulations, a QRM is generally defined as a mortgage meeting the requirements of a qualified mortgage under the CFPB’s QM Rule described above. For securitizations that include mortgage loans which are not QRMs, securitizers are required to retain at least a 5% first-loss position, or a 5% pro rata share of all securities issued or a combination of a first-loss position and pro rata share for up to seven years. Radian Mortgage Capital does not expect to conduct securitizations that include mortgage loans that are not QRMs, but if it were to choose to do so in the future, its non-QRM securitizations would be subject to risk retention requirements.

Other

The Dodd-Frank Act establishes a Federal Insurance Office within the U.S. Department of the Treasury (the “FIO”). While the FIO does not have a general supervisory or regulatory authority over the business of insurance, the director of this office performs various functions with respect to insurance, such as serving as a non-voting member of the Financial Stability Oversight Council. It is difficult to predict whether legislators or other executive agencies will pursue the development and implementation of federal standards for the mortgage insurance industry outside of the FHFA. Any divergence from the current system of state regulation could significantly change compliance burdens and possibly impact our financial condition.

In addition, Section 1473 of the Dodd-Frank Act establishes minimum requirements to be implemented by states regarding the registration and supervision of appraisal management companies, including Radian Valuation Services.

RESPA

Settlement service providers in connection with the origination or refinance of a federally regulated mortgage loan are subject to RESPA and Regulation X. RESPA authorizes the CFPB, the U.S. Department of Justice, state attorneys general and state insurance commissioners to bring civil enforcement actions, and also provides for criminal penalties and private rights of action.

Mortgage insurance, title insurance, brokerage services and other products and services provided by Radian’s affiliates are considered settlement services for purposes of RESPA. The anti-referral fee and anti-kickback provisions of Section 8 of RESPA generally provide, among other things, that settlement service providers are prohibited from paying or accepting anything of value in connection with the referral of a settlement service or sharing in fees for those services. RESPA also prohibits requiring the use of an affiliate for settlement services and requires certain information to be disclosed if an affiliate is used to provide the settlement services. In addition to mortgage insurance provided by Radian Guaranty, our homegenius businesses offer an array of services to our customers, including real estate brokerage, valuation, hybrid appraisal, title and closing services, many of which may be considered settlement services for purposes of RESPA, and therefore, may be subject to the anti-referral fee, anti-kickback and required use provisions of RESPA.

RESPA also establishes a number of mortgage loan servicing requirements. Radian Mortgage Capital currently acts as a master servicer for the loans acquired by the conduit, and in this role, oversees a subservicer that performs the day-to-day servicing of conduit loans. As master servicer, Radian Mortgage Capital is subject to the mortgage loan servicing requirements under RESPA, including those relating to servicing transfers, responding to consumer information requests, resolution of notices of error, force-placed insurance, early intervention and continuity of contact with delinquent borrowers, loss mitigation, general servicing policies and procedures, escrow account maintenance and service provider oversight.

40

Part I. Item 1. Business

The SAFE Act

The SAFE Act and its state law equivalents require mortgage loan originators to be licensed with state agencies in the states in which they operate and/or registered with the Nationwide Mortgage Licensing System and Registry (the “Registry”). The Registry is a database established by the Conference of State Bank Supervisors and the American Association of Residential Mortgage Regulators that tracks the licensing and eligibility requirements of loan originators. Among other things, the database was established to support the licensing of mortgage loan originators by each state.

As part of this licensing and registration process, loan originators who are employees of institutions other than depository institutions or certain of their subsidiaries that, in each case, are regulated by a federal banking agency, must generally be licensed under the SAFE Act guidelines enacted by each state in which they engage in loan origination activities and registered with the Registry. Additionally, most states define underwriting and loan processing as a clerical and administrative duty that must be performed under the supervision of a licensed mortgage loan originator.

Mortgage Insurance Cancellation

The HPA imposes certain cancellation and termination requirements for borrower-paid private mortgage insurance with respect to “residential mortgage transactions” as defined in the HPA. Provided that certain conditions are satisfied, the HPA generally provides that borrower-paid private mortgage insurance may be canceled at the request of the borrower once the principal balance of the mortgage is first scheduled to reach 80% of the home’s original value based on the loan’s initial amortization schedule, or reaches 80% of the home’s original value based on actual payments.

In addition, provided that certain conditions are satisfied, the HPA also generally provides that borrower-paid private mortgage insurance is subject to servicer-initiated automatic termination once the principal balance of the mortgage is first scheduled to reach 78% of the home’s original value based on the loan’s initial amortization schedule (or, if the loan is not current on that date, on the date that the loan becomes current). The HPA further provides that borrower-paid private mortgage insurance on most loans is subject to final termination following the date that is the midpoint of the loan’s amortization period (or, if the loan is not current on that date, on the date that the loan becomes current).

The HPA also provides that, in general, within 45 days after termination or cancellation of a borrower-paid private mortgage insurance policy in accordance with the requirements of the relevant section of the HPA, all remaining unearned premiums for private mortgage insurance must be returned to the borrower by the servicer, and that within 30 days after notification by the servicer, a mortgage insurer that is in possession of any unearned premiums of the borrower must transfer to the servicer an amount equal to the amount of unearned premiums for repayment.

The HPA also establishes special rules for the termination of private mortgage insurance in connection with loans that are “high risk.” The HPA does not define “high risk” loans but leaves that determination to the GSEs for loans they purchase, and to lenders for any other loan. For “high risk” loans originated in excess of conforming loan limits, provided that certain conditions are satisfied, the servicer is required to initiate termination once the principal balance of the mortgage is first scheduled to reach 77% of the home’s original value based on the loan’s initial amortization schedule.

Although not provided in the HPA, the GSEs’ guidelines also currently provide that when certain conditions are satisfied, borrowers can request cancellation of borrower-paid mortgage insurance for most loans when the LTV, based upon the current value of the home, is either 75% or less or 80% or less, depending on the seasoning of the loan and other factors. The GSEs may change these guidelines in the future, including by expanding their mortgage insurance cancellation requirements, which could negatively impact our businesses. In “Item 1A. Risk Factors,” see “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses” and “Our mortgage insurance business faces intense competition.”

The Fair Credit Reporting Act (the “FCRA”)

The FCRA imposes restrictions on the permissible use of credit report information and disclosures that must be made to consumers when information from their credit reports is used. The FCRA has been interpreted by the Federal Trade Commission to require mortgage insurance companies to provide “adverse action” notices to consumers under the “insurance prong” of FCRA in the event an application for mortgage insurance is declined or a higher premium is charged based on the use, wholly or partly, of information contained in the consumer’s credit report.

Privacy and Information Security—Gramm-Leach-Bliley Act of 1999 (the “GLBA”) and Other Regulatory Requirements

In the ordinary course of our operations, we, and certain of our subsidiaries, maintain large amounts of confidential information, including non-public personal information on consumers and our employees. We and our customers are subject to a variety of privacy and information security laws and regulations. The GLBA, which consists of both a Privacy Rule and a Safeguards Rule, imposes privacy and security requirements on financial institutions, including obligations to protect and safeguard consumers’ nonpublic personal information and records, and limitations on the use, re-use and sharing of such information. The GLBA is enforced by state regulators and by federal regulatory agencies.

41

Part I. Item 1. Business

Effective June 9, 2023, the Federal Trade Commission implemented several delayed amendments to the GLBA Safeguards Rule. The amended Safeguards Rule includes, among other things, new requirements for risk assessments and access controls, such as multifactor authentication, as well as enhanced data inventory, classification and disposal practices. On November 13, 2023, the FTC published additional amendments to the Safeguards Rule regulations for financial institutions subject to its jurisdiction to add cyber event notification requirements, which are scheduled to take effect on May 13, 2024.

In addition, many states have enacted privacy and data security laws that impose compliance obligations beyond the GLBA, such as: requiring notification in the event that a security breach results in a reasonable belief that unauthorized persons may have obtained access to consumer nonpublic personal information; imposing additional restrictions on the sharing and use of consumers’ personal information; affording consumers new rights of access, correction and deletion of their personal information and rights to appeal; imposing affirmative consent and/or opt out requirements for targeted advertising and other activities; and creating new private rights of action for data breaches. See “State Regulation—Privacy” above.

Federal and state agencies have increased their focus on compliance obligations related to privacy, data security and cybersecurity. The CFPB, NYDFS, Federal Trade Commission, Office of the Comptroller of the Currency and non-governmental regulatory agencies, such as the Financial Industry Regulatory Authority (FINRA), have announced new compliance measures and enforcement efforts designed to monitor and regulate the protection of personal consumer data, including with respect to: the development and delivery of financial products and services; underwriting; mortgage servicing; credit reporting; digital payment systems; and vendor management. For information regarding the NYDFS’ cybersecurity regulations and the California Consumer Privacy Act, under “State Regulation” above, see “Information Security” and “Privacy.”

Fair Lending and Fair Servicing

The federal Fair Housing Act, part of the Civil Rights Act of 1968, makes it unlawful for any person whose business includes engaging in residential real estate-related transactions to: (i) discriminate in housing-related lending activities against any person on a prohibited basis or (ii) for any person to discriminate in the sale or rental of housing “or in the provision of services or facilities in connection therewith,” to any person because of a prohibited basis, such as race, national origin, familial status, sex, disability or religion.

Similarly, the Equal Credit Opportunity Act (“ECOA”) and Regulation B under ECOA make it unlawful for a creditor to discriminate in any aspect of a credit transaction against an applicant on a prohibited basis during any aspect of a consumer or business credit transaction or make any oral or written statement to applicants or prospective applicants that would discourage on a prohibited basis a reasonable person from making or pursuing an application.

These laws seek to address discrimination in lending and other housing-related activity by prohibiting discrimination that is intentional or where a facially neutral policy or practice has a “disparate impact;” that is, that it disproportionately excludes or burdens persons on a prohibited basis, unless the activity is necessary to address a substantial, legitimate, nondiscriminatory business interest and there is no less discriminatory alternative that would achieve the same legitimate objective.

As a provider of products and services that support residential real estate transactions and the mortgage production and financing process, fair lending and servicing laws may impact the way we deliver or conduct our products and services, including in response to customer requirements.

Federal Consumer Protection Laws

As certain of our current and potential future business activities are directed at consumers or affect the provision of real estate and mortgage-related services provided to consumers by others, we may be subject to a number of federal consumer protection laws, in addition to those referenced above. In addition to the laws and regulations discussed elsewhere in this Regulation section, these laws may include:

■The Truth in Lending Act and Regulation Z, requiring disclosures of mortgage loan costs and other notices to consumers, prohibiting certain compensation to loan originators, steering and other loan origination practices, establishing a number of requirements for mortgage servicers and imposing requirements on loan owners for loan ownership transfers;

■The Fair Debt Collection Practices Act, regulating debt collection communications and other activities;

■Prohibition on Unfair, Deceptive or Abusive Acts or Practices, prohibiting unfair, deceptive or abusive acts or practices in connection with any transaction with a consumer for a consumer financial product or service, or the offering of a consumer financial product or service;

■CAN-SPAM Act, regulating commercial and marketing email, including the right of recipients to have the sender stop sending emails;

■The Telephone Consumer Protection Act and Do Not Call regulations, regulating and restricts certain marketing-related phone calls, text messages and facsimiles; and

■Electronic Signatures in Global and National Commerce Act (E-Sign Act), allowing the use of electronic records to satisfy requirements that must be provided in writing if the consumer has affirmatively consented.

42

Part I. Item 1. Business

We may also be required to comply with state laws similar to these federal consumer protection laws to the extent applicable to our businesses.

Basel III

Over the past few decades, the Basel Committee on Banking Supervision (the “Basel Committee”) has established international benchmarks for assessing banks’ capital adequacy requirements (“Basel III”). Included within those benchmarks are capital standards related to residential lending and securitization activity and, importantly for private mortgage insurers, the capital treatment of mortgage insurance on those loans. These benchmarks are then interpreted and implemented via rulemaking by U.S. banking regulators.

In July 2013, the U.S. banking regulators promulgated regulations, referred to as the “U.S. Basel III Rules,” to implement significant elements of the Basel framework. The U.S. Basel III Rules, among other things, revise and enhance the U.S. banking agencies’ general risk-based capital rules. Today, the U.S. Basel III Rules assign a risk weight to loans secured by one-to-four family residential properties. Generally, under the U.S. Basel III Rules in place today, the explicit government guarantees (FHA/VA/USDA) receive a 0% risk weight, and Fannie Mae and Freddie Mac related loans receive a 20% risk weight. Non-government-related mortgage exposures secured by a first-lien on a one-to-four family residential property that are prudently underwritten and that are performing according to their original terms receive a 50% risk weighting. All other one-to-four family residential mortgage loans are assigned a 100% risk weight.

In December 2014, the Basel Committee issued a proposal for further revisions to Basel III. It proposed adjustments to the risk weights for residential mortgage exposures that take into account LTV ratio and the borrower’s ability to service a mortgage, which were not previously addressed by Basel III. The proposed LTV ratio did not take into consideration any credit enhancement, including private mortgage insurance, but in March 2015, the U.S. banking regulators clarified that for purposes of the U.S. Basel III Rules, calculation of LTV ratios can account for credit enhancement such as private mortgage insurance in determining whether a loan is made in accordance with prudent underwriting standards for purposes of receiving the preferred 50% risk weight. In December 2015, the Basel Committee released a second proposal which retained the LTV provisions of the initial draft, but not the provisions pertaining to a borrower’s ability to service a mortgage (the “2015 Basel Committee Proposal”).

The revised and final recommendations from the Basel Committee with respect to Basel III were published in December 2017 (the “2017 Basel Committee III Recommendations”) and included finalized risk weighting guidelines for residential mortgage exposures. These rules recognize guarantees provided by sovereign governments (such as FHA, VA, USDA and Ginnie Mae) as offsetting the capital requirements, resulting in a 0% risk weight. While the 2017 Basel Committee III Recommendations include consideration of LTV ratios, including the impact of credit enhancement provided by third-party private mortgage insurance and the GSEs on LTV ratios, the credit enhancement provided by third-party private mortgage insurance and the GSEs would have higher risk weightings than the explicitly government guaranteed products, putting loans insured by private mortgage insurance at a disadvantage.

Most recently, on July 27, 2023, the U.S. federal banking agencies published a notice of proposed rulemaking (“NPR”) to implement the remaining elements of the Basel III recommendations that were developed by the international Basel Committee on Banking Supervision. The proposal applies to all banking organizations with $100 billion or more in total consolidated assets and their subsidiary depositary institutions, and covers risk-weighted asset calculations for credit, market, credit valuation adjustment, and operational risks. As proposed, the NPR would adjust risk weights for low down payment loans that are held in a bank’s portfolio, generally increasing the risk weights for higher LTV loans without taking into account credit enhancement, such as private mortgage insurance, on those loans in determining the risk weighting. Currently, we expect the NPR to have a limited impact on our mortgage insurance business, as most of the loans that we insure are sold to the GSEs. If the NPR is adopted as proposed, the rule is expected to impact how banks allocate capital and could impact the pricing and availability of financial services and products, among other things. While the outcome of the rulemaking process is currently undetermined, if adopted as proposed, banks subject to the rule may be disincentivized to hold loans in portfolio, which could provide greater opportunities for growth in secondary market transactions.

Risks Related to Regulatory Matters

Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity.

In order to be eligible to insure loans purchased by the GSEs, mortgage insurers such as Radian Guaranty must meet the GSEs’ eligibility requirements, or PMIERs. The PMIERs are comprehensive, covering virtually all aspects of the business of a private mortgage insurer, including extensive risk management and operational requirements and the financial requirements discussed below. See “Item 1. Business—Regulation—Federal Regulation—GSE Requirements for Mortgage Insurance Eligibility.” If Radian Guaranty is unable to satisfy the requirements set forth in the PMIERs, including the financial requirements discussed below, the GSEs have significant discretion to impose various remedial measures on Radian Guaranty, including restricting Radian Guaranty from conducting certain types of business with them or in the extreme, suspending or terminating Radian Guaranty’s eligibility to insure loans purchased by the GSEs.

The PMIERs include financial requirements incorporating a risk-based framework that requires a mortgage insurer’s Available Assets to meet or exceed its Minimum Required Assets. Although not required under the PMIERs, to ensure ongoing compliance, mortgage insurers typically have maintained an amount of Available Assets significantly in excess of their Minimum Required Assets, and we refer to such excess as a PMIERs “cushion.” The PMIERs financial requirements include increased financial requirements for defaulted loans, with increasing Minimum Required Assets as defaults age, as well as for performing loans that present a higher likelihood of default and/or certain credit characteristics, such as higher LTVs and lower FICO credit scores.

Radian Guaranty’s PMIERs cushion, and ultimately, its ability to continue to comply with the PMIERs financial requirements could be impacted by, among other factors: (i) the volume and product mix of our NIW; (ii) factors affecting the performance of our mortgage insurance portfolio, including the level of new defaults and prepayments; (iii) for existing defaults, the aging of these existing defaults and whether they are subject to, and remain in, mortgage forbearance programs, and the ultimate losses we incur on new or existing defaults; (iv) the amount of credit that we receive under the PMIERs financial requirements for our third-party reinsurance transactions; and (v) potential amendments or updates to the PMIERs.

The GSEs may amend the PMIERs at any time and also have broad discretion to interpret the PMIERs, which could impact the calculation of Radian Guaranty’s Available Assets and/or Minimum Required Assets. The most recent large-scale revisions to PMIERs became effective in 2019, and the PMIERs have been further updated since then to address specific matters, including the COVID-19 pandemic. We expect the GSEs to continue to update the PMIERs in the future as they may deem necessary. For further information, see “Item 1. Business—Regulation—Federal Regulation—GSE Requirements for Mortgage Insurance Eligibility.”

If Radian Guaranty’s PMIERs cushion is materially decreased, we may be required or otherwise choose to: (i) retain capital in Radian Guaranty and/or contribute additional capital to Radian Guaranty; (ii) alter our strategy with respect to our NIW by limiting the type and volume of business we are willing to write for certain products; or (iii) seek additional capital relief through reinsurance or otherwise, which may not be available on acceptable terms or on terms that would be approved by the GSEs.

Compliance with the PMIERs financial requirements could impact our holding company liquidity if additional capital support for Radian Guaranty is required for Radian Guaranty to increase its PMIERs cushion or maintain compliance. The amount of capital that Radian Group could be required to contribute to Radian Guaranty for these purposes is uncertain but could be significant. See “Our sources of liquidity may be insufficient to fund our obligations.” Further, if Radian Guaranty becomes capital constrained, it may be more difficult for Radian Guaranty to return capital to Radian Group, which would compound the negative liquidity impact to Radian Group of the contributions it may be required to make to Radian Guaranty and leave less liquidity to satisfy Radian Group’s other obligations. Depending on the amount of liquidity that is utilized from

44

Part I. Item 1A. Risk Factors

Radian Group, we may be required (or may decide) to seek additional capital by incurring additional debt, issuing additional equity or selling assets, which we may not be able to do on favorable terms, if at all.

The PMIERs prohibit Radian Guaranty from engaging in certain activities such as insuring loans originated or serviced by an affiliate (except under certain circumstances) and require Radian Guaranty to obtain the prior consent of the GSEs before taking many actions, which may include, among other things, entering into certain intercompany agreements, settling loss mitigation disputes with customers and commuting risk. These restrictions could prohibit or delay Radian Guaranty from taking certain actions that would be advantageous to it or to Radian Group.

Loss or threat of loss of Radian Guaranty’s eligibility status with the GSEs would have an immediate and material adverse impact on the franchise value of our mortgage insurance business and our future prospects, as well as a material negative impact on our future results of operations and financial condition.

Our insurance subsidiaries are subject to comprehensive state insurance regulations and other requirements, which we may fail to satisfy.

We and our insurance subsidiaries are subject to comprehensive, detailed regulation by the insurance regulators in the states where they are domiciled or licensed to transact business. These regulations are principally designed for the protection of our insurance policyholders rather than for the benefit of Radian Group’s investors. Insurance laws vary from state to state, but generally grant broad supervisory powers to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including the power to revoke or restrict an insurance company’s ability to write new business.

Among other matters, the state insurance regulators impose various capital requirements on our insurance subsidiaries. State insurance capital requirements for our mortgage insurance subsidiaries include Risk-to-capital ratios, other risk-based capital measures and surplus requirements that may limit the amount of insurance that our mortgage insurance subsidiaries write or the ability of our insurance subsidiaries to distribute capital to Radian Group. Similarly, our title insurance subsidiary is required to maintain statutory premium reserves that vary by state and are subject to periodic reviews of certain financial performance ratios, the results of which could result in additional capital requirements in states where it is licensed.

Among other things, our failure to maintain adequate levels of capital in our mortgage insurance or title insurance subsidiaries could lead to intervention by the various insurance regulatory authorities, which could materially and adversely affect our business, business prospects and financial condition. In addition, the GSEs and our mortgage insurance customers may decide not to conduct new business with Radian Guaranty (or may reduce current business levels) or impose restrictions on Radian Guaranty if it is not in compliance with applicable state insurance requirements. The franchise value of our mortgage insurance business likely would be significantly diminished if we were prohibited from writing new business or restricted in the amount of new business we could write in one or more states. For additional information about statutory surplus and other state insurance requirements, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Mortgage Insurance,” as well as Note 16 of Notes to Consolidated Financial Statements.

The mortgage insurance industry has always been highly competitive with respect to pricing. Our mortgage insurance subsidiaries’ premium rates and policy forms are generally subject to regulation in every state in which they are licensed to transact business. These regulations are intended to protect policyholders against the adverse effects of excessive, inadequate or unfairly discriminatory rates and to encourage fair competition in the insurance marketplace. The increased use by the insurance industry generally of risk-based pricing systems that establish premium rates based on more attributes than previously considered, and of algorithms, artificial intelligence and data and analytics, has led to additional regulatory scrutiny of premium rates and of other matters such as discrimination in pricing and underwriting, data privacy and access to insurance. We may be subject to regulatory inquiries or examinations with respect to our mortgage insurance premium rates and policy forms.

Similarly, our title insurance business is subject to extensive rate regulation by the applicable state agencies in the states in which it operates. Given that the premium rates for our insurance subsidiaries are highly regulated, we could lose business opportunities and fail to successfully implement our business strategies if our rates are deemed non-compliant or are subject to investigation, if new rates and policy forms are not approved as may be required, or if we are otherwise unable to respond to competitor pricing actions and our customers’ demands in a timely and compliant manner.

See “Item 1. Business—Regulation—State Regulation” for more information on existing regulatory requirements and potential further changes to existing requirements that could result if one or more states were to institute the Model Act that was adopted by the NAIC in August 2023.

Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.

Changes in the GSEs’ business practices and other actions of the FHFA and GSEs can significantly impact the functioning of the housing finance system. Because traditional mortgage insurance is an important component of this system and because our businesses depend on the health of the housing finance system and housing markets in particular, these actions have impacted, and future actions could further impact, our business operations and performance. The FHFA has been

45

Part I. Item 1A. Risk Factors

the conservator of the GSEs since 2008 and has the authority to control and direct their operations. Given that the Director of the FHFA is removable by the President at will, the agency’s agenda and its policies and actions are influenced by the then-current administration. The increased role that the federal government has assumed in the residential housing finance system through the GSE conservatorships may increase the likelihood that the business practices of the GSEs change, including through administration changes and actions.

Our current business structure is highly dependent on the GSEs, which are the primary beneficiaries of most of our mortgage insurance policies. Changes in the business practices of the GSEs, which can be implemented by the GSEs acting independently or through the FHFA, could negatively impact our business and financial performance. Examples of potential changes that could impact our business may include, without limitation:

■eligibility requirements for a mortgage insurer to become and remain an approved eligible insurer for the GSEs;

■underwriting standards on mortgages they purchase;

■policies or requirements that may result in a reduction in the number of mortgages they acquire, including benchmarks established by the FHFA for the amount of certain loans that may be purchased by the GSEs;

■the national conforming loan limit for mortgages they acquire, in particular as this limit compares to loan limits set by the FHA;

■the level of mortgage insurance they require;

■the terms on which mortgage insurance coverage may be canceled before reaching the cancellation thresholds established by law, including if the GSEs change or expand their cancellation practices as a result of policy goals, changing risk tolerances or otherwise;

■the terms required to be included in mortgage insurance policies that cover the loans they acquire, including limitations on the ability of mortgage insurers to mitigate losses on insured mortgages that are in default;

■the programs established by the GSEs that are intended to avoid or mitigate loss on insured loans;

■the amount of loan level price adjustments or guarantee fees, which may result in a higher cost to borrowers, that the GSEs charge on loans that require mortgage insurance; and

■the degree of influence that the GSEs have over a mortgage lender’s selection of the mortgage insurer providing coverage.

The GSEs have changed their business practices to support equitable access to, and affordability of, mortgage credit, in particular to low- and moderate-income borrowers and underserved communities. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices.” As required by the FHFA, each of the GSEs has prepared and filed three-year Equitable Housing Finance Plans that describe each GSE’s planned efforts to advance equity in housing finance, including proposals to reduce mortgage costs for historically underserved borrowers. In accordance with their plans, both Fannie Mae and Freddie Mac have launched their own Special Purpose Credit Programs (“SPCPs”) and have worked with lenders to purchase loans originated through lender SPCPs. While details on any future changes remain uncertain, both Fannie Mae’s and Freddie Mac’s plans note that their programs could consider modifications to mortgage insurance requirements. The plans also include expected activity to address alternative credit and data in underwriting, property appraisals, and title insurance, among others. The FHFA and GSEs expect to continue to update these plans annually. To implement these plans or to otherwise support the FHFA’s mandate regarding increasing the accessibility and affordability of mortgage credit, the GSEs may pursue new products and activities, or alter existing policies and practices, including in ways that could negatively impact Radian Guaranty’s IIF, results of operations or financial condition. In addition, in furtherance of these policy objectives, Radian Guaranty and/or one or more of the mortgage insurers may pursue initiatives outside of their customary business activities, the success of which may be measured based on how well the initiative was able to advance accessibility and affordability of mortgage credit rather than by traditional profitability and return measures. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices—Administrative Reform—Access and Affordability” for further discussion regarding these and other changes to the GSEs’ business practices.

In February 2022, the FHFA finalized the ERCF, which establishes new increased capital requirements for the GSEs, and the FHFA also has proposed new liquidity requirements for the GSEs. Since finalizing this rule, FHFA has adopted several amendments to the ERCF, most recently by a rule adopted in November 2023. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for further information. Taken together, compliance with the increased capital requirements imposed by the ERCF and the proposed new GSE liquidity requirements could significantly alter the business practices and operations of the GSEs, including potentially resulting in an increase in GSE pricing and a decrease in their use of credit risk transfer. An increase in GSE pricing could make alternatives to the GSEs such as FHA insured loans or the private securitization market more attractive, which could reduce the GSEs’ market position and reduce the number of loans available for private mortgage insurance.

Further, the GSEs may seek to amend the PMIERs financial requirements in the future to better align with the ERCF and the proposed GSE liquidity requirements, once finalized. Changes to the PMIERs to better align with the ERCF could include:

46

Part I. Item 1A. Risk Factors

(i) an increase in the level of Radian Guaranty’s required capital and (ii) a decrease in the amount of PMIERs’ capital relief that Radian Guaranty receives for existing or future credit risk transfer transactions, including reinsurance or mortgage insurance-linked notes transactions. It remains uncertain if, when and how the PMIERs ultimately may be amended to better align with the ERCF. For a discussion of these and other potential changes to the PMIERs, see “Item 1. Business—Regulation—Federal Regulation—GSE Requirements for Mortgage Insurance Eligibility.”

The GSEs have in the past and may in the future offer new products and activities in pursuit of their business strategies, including credit risk transfer transactions and structures that compete with private mortgage insurance. If these products or credit risk transfer transactions and structures were to materially displace primary loan level or standard levels of mortgage insurance, the amount of mortgage insurance we write may be reduced, which could negatively impact our franchise value, results of operations and financial condition. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for further discussion, including with respect to a final rule released by the FHFA regarding the process for how it will consider and approve new GSE activities and products.

The structure of the residential housing finance system could be altered in the future, including as a result of comprehensive housing reform legislation. Since the FHFA was appointed as conservator of the GSEs, there has been a wide range of legislative proposals to reform the U.S. housing finance market. In conjunction with these proposals, there has been ongoing debate about the roles that the federal government and private capital should play in the housing finance system. To the extent new legislative action alters the existing GSE charters without explicit preservation of the role of private mortgage insurance for high-LTV loans, our business could be adversely affected. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for a discussion of the future of housing finance in the U.S., including potential objectives for future reform.

Although we believe that traditional private mortgage insurance will continue to play an important role in any future housing finance structure, developments in the practices of the GSEs, including potentially new federal legislation, changes to existing statutes, rules or regulations, or changes in the GSEs’ business practices that reduce the level of private mortgage insurance coverage used by the GSEs as credit enhancement, or even eliminate the requirement, may diminish the franchise value of our mortgage insurance business and materially and adversely affect our business prospects, results of operations and financial condition.

Legislation and administrative and regulatory changes and interpretations could impact our businesses.

Our businesses are subject to and may be impacted by many federal and state lending, insurance and consumer laws and regulations. See “Item 1. Business—Regulation” for a discussion of significant state and federal regulations and other requirements of the GSEs that are applicable to our businesses. Changes in these laws and regulations or the way they are interpreted or applied, as well as changes in other laws and regulations that may affect corporations more generally, could adversely affect our results of operations, financial condition and business prospects. In addition, our businesses could be impacted by new legislation or regulations, including changes that are not currently contemplated and which could occur at any time. While we have established policies and procedures to comply with applicable laws and regulations, many such laws and regulations are complex, and it is not possible to predict the eventual scope, duration or outcome of any reviews or investigations nor is it possible to predict their effect on us or the industries in which we participate.

Risks Related to our Business Operations

Our success depends on our ability to assess and manage our mortgage insurance underwriting risks; the mortgage insurance premiums we charge may not be adequate to compensate us for our liability for losses and the amount of capital we are required to hold against our insured mortgage risks. We expect to incur losses for future mortgage defaults beyond what we have reserved for in our financial statements.

The estimates and expectations we use to establish premium rates in our mortgage insurance business are based on assumptions made at the time our insurance is written. Our mortgage insurance premium rates are based on, among other items, our expectations about competitive and economic conditions and our cost of capital, as well as a broad range of other factors and risk attributes that we consider in developing our assumptions about the credit performance of the loans we insure and the economic benefits we expect to receive from our insurance policies. Our assumptions may ultimately prove to be inaccurate, especially in a period of high market volatility and economic uncertainty, or if there is a change in law or the GSEs’ business practices that alter the performance of the loans we have insured in ways that are inconsistent with our assumptions, including the amount of premium we expect to receive from such insurance. The premium structure we apply is subject to approval by state regulatory agencies, which can delay or limit our ability to increase our premiums if further filings or approvals are necessary to institute pricing adjustments.

If the risk underlying a mortgage loan that we have insured develops more adversely than we anticipated, we generally cannot increase the premium rates on this in-force business, cancel coverage or elect not to renew coverage to mitigate the effects of such adverse developments. Similarly, we cannot adjust our premiums if the amount of capital we are required to hold against our insured risks increases from the amount we were required to hold at the time a policy was written or if the premiums we expected to receive from such insurance are less than anticipated, whether due to a change in the GSEs’ business practices or otherwise. As a result, if we are unable to compensate for or offset the increased capital requirements in

47

Part I. Item 1A. Risk Factors

other ways, the returns on our business may be lower than we assumed or expected. Our premiums earned and the associated investment income on those premiums may ultimately prove to be inadequate to compensate for the losses that we may incur and may not provide an adequate return on capital that may be required. As a result, our results of operations and financial condition could be negatively impacted.

From time to time, we change the processes we use to underwrite loans, including by automating certain underwriting processes and relying on information and processes of the GSEs. For example: we rely on information provided to us by lenders that was obtained from automated income verification tools in lieu of requiring traditional income documentation; we also accept GSE appraisal waivers for certain refinance loans that may or may not require an onsite inspection of the property; and for certain purchase transactions, we accept desktop appraisals, when permitted by the GSEs, where the appraiser relies on data obtained from alternative methods or sources to identify property characteristics and condition and does not complete a current inspection of the subject property. Our acceptance of automated processes, valuation alternatives, and verification tools, may produce results that differ from the results that would have been determined using our prior processes and methods, which could affect our pricing and risk assessment. We also continue to further automate our underwriting processes to incorporate risk-informed decision making, and it is possible that our automated processes result in our insuring loans that we would not otherwise have insured under our prior processes or would have insured at a different premium rate.

Additionally, in accordance with industry practice, we generally do not establish reserves in our mortgage insurance business until we are notified that a borrower has failed to make at least two monthly payments when due. Because our mortgage insurance reserving does not account for the impact of future losses that we expect to incur with respect to performing (non-defaulted) loans, our obligation for ultimate losses that we expect to incur at any period end is not reflected in our financial statements, except if a premium deficiency exists. A premium deficiency reserve would be recorded if the present value of expected future losses and expenses exceeds the present value of expected future premiums and already established loss reserves on the applicable loans. As future defaults are not reflected in our mortgage insurance loss reserves, our loss reserves could increase significantly in future periods if we experience a high volume of new defaults in future periods, which would negatively impact our results of operations and financial condition.

If the estimates we use in establishing mortgage insurance loss reserves are incorrect, we may be required to take unexpected charges to income, which could adversely affect our results of operations.

We establish loss reserves in our mortgage insurance business to provide for the estimated cost of future claims on defaulted loans. Setting our loss reserves requires significant judgment by management with respect to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may not prove to be accurate, especially in the event of an extended economic downturn or a period of market volatility and economic uncertainty. Because claims paid may be substantially different than our loss reserves, our loss reserves may be insufficient to satisfy the full amount of claims that we ultimately have to pay. In the past, changes to our loss reserve estimates have impacted, and could again in the future impact, our results of operations and financial condition.

High levels of defaults and delays in foreclosures could delay our receipt of claims, resulting in an increase in the period of time that a loan remains in our inventory of defaulted mortgage loans, and as a result, the Claim Severity. Generally, foreclosure delays do not stop the accrual of interest or affect other expenses on a loan, and unless a loan is cured during such delay, once title to the property ultimately is obtained and a claim is filed, our paid claim amount may include additional interest and expenses, increasing the Claim Severity. Although the rate of new defaults has largely returned to pre-pandemic levels and many pandemic-related defaulted loans have cured, a portion of the defaulted loans in our insured portfolio remain in COVID-19 mortgage forbearance programs. It is difficult to predict whether these loans will cure, including through modification, when forbearance ends or how many of these loans will result in a claim.

If our loss reserve estimates are inadequate, we may be required to increase our reserves, which could have a material adverse effect on our results of operations and financial condition.

Our Loss Mitigation Activity could negatively impact our customer relationships.

As part of our claims management process, we pursue opportunities to mitigate losses both before and after we receive claims, including processes to ensure claims are valid.

Our Loss Mitigation Activities and claims paying practices have in the past resulted in disputes with certain of our customers and in some cases, damaged our relationships with customers, resulting in a loss of business. While these past disputes have been resolved, a risk remains that our Loss Mitigation Activities or claims paying practices could in the future have a negative impact on our relationships with customers or potential customers. Further, disputes with our customers that are not resolved could result in arbitration or judicial proceedings, requiring significant legal expenses. To the extent that past or future Loss Mitigation Activities or our claims paying practices impact our customer relationships, it could result in the potential loss of business and our competitive position could be adversely affected, which could negatively impact our results of operations.

Part I. Item 1A. Risk Factors

Reinsurance may not be available, affordable or adequate to protect us against losses.

We use reinsurance as a capital and risk management tool. We have distributed risk through traditional quota share and excess-of-loss reinsurance arrangements, as well as to investors through the capital markets using mortgage insurance-linked notes transactions.

The availability and cost of reinsurance are subject to market conditions beyond our control, including reinsurer and investor demand for mortgage credit. No assurance can be given that reinsurance will remain available to us in amounts that we consider sufficient and at rates and upon terms that we consider acceptable. Accordingly, we may be forced to incur additional expenses for reinsurance or may not be able to obtain sufficient reinsurance on acceptable terms, which could cause us to increase the amount of risk we retain, and negatively affect our ability to mitigate losses in our portfolio, the returns we are able to achieve on the business we write and our ability to write future business. Further, reinsurance does not relieve us of our direct liability to policyholders; therefore, if the reinsurer is unable or unwilling to meet its obligations to us, we remain liable to make claims payments to our policyholders. As a result, our reinsurance arrangements do not fully eliminate our obligation to pay claims, and we have assumed counterparty credit risk with respect to our inability to recover amounts due from reinsurers.

We use reinsurance to manage Radian Guaranty’s capital position under the PMIERs financial requirements. Among other benefits, our risk distribution transactions have collectively reduced our required capital, including by significantly reducing our Required Minimum Assets under the PMIERs. The initial and ongoing credit that we receive under the PMIERs financial requirements for these risk distribution transactions is subject to the periodic review of the GSEs and could be influenced by the ERCF, which, in its current form, significantly increases the capital requirements for the GSEs and provides the GSEs with a reduced amount of credit for their own credit risk transfer activities. See “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.” If the GSEs revise the PMIERs in the future to align with the final form of the ERCF, such alignment could reduce the credit that Radian Guaranty receives for reinsurance under the PMIERs, which could negatively impact our strategic approach to risk management and risk distribution.

If we are unable to obtain sufficient reinsurance on acceptable terms or to collect amounts due from our reinsurers, or if we receive less PMIERs capital relief for our reinsurance transactions, it could have a material adverse effect on our business, financial condition and results of operations.

If the length of time that our mortgage insurance policies remain in force declines, it could result in a decrease in our future revenues.

Most of our primary IIF consists of policies for which we expect to receive premiums in the future, typically through Monthly Premium Policies, and as a result, a significant portion of our earned premiums are derived from insurance that was written in prior years. The percentage of our insurance certificates that remain in force for a specified period of time, which we refer to as the Persistency Rate, is a significant driver of our future revenues, with a lower overall Persistency Rate generally reducing our future revenues. As a result, the ultimate profitability of our mortgage insurance business is affected by mortgage prepayment speeds for the loans that we insure.

Factors affecting the length of time that our insurance remains in force include:

■prevailing mortgage interest rates compared to the mortgage rates on our IIF, which affects the incentive for borrowers to refinance (i.e., lower current interest rates make it more attractive for borrowers to refinance and receive a lower interest rate);

■the current amount of equity that borrowers have in the homes underlying our IIF:

▪borrowers with significant equity in their homes may refinance their loans without the need for mortgage insurance;

▪the HPA requires servicers to cancel mortgage insurance when a borrower’s LTV ratio meets or is scheduled to meet certain levels, generally based on the original value of the home and subject to various conditions; and

▪the GSEs’ mortgage insurance cancellation guidelines, which apply more broadly than the HPA, allow for cancellation of mortgage insurance, at the borrowers’ request, based on the home’s current value if certain LTV and seasoning requirements are met and the borrowers have an acceptable payment history. Higher home price appreciation increases the likelihood of borrowers reaching the cancellation thresholds, which could negatively impact persistency. For more information about the GSEs’ guidelines and business practices and how they may change, see “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses.”

■the credit policies of certain lenders, which impact the ability of homeowners to refinance loans; and

■economic conditions that can affect a borrower’s decision to pay off a mortgage earlier than required, including the strength of the housing market, which impacts a borrower’s prospects for selling their existing home and finding a suitable and affordable new home.

49

Part I. Item 1A. Risk Factors

If these or other factors cause a decrease in the length of time that our Recurring Premium Policies, for which we expect to receive premiums in the future, remain in force, our future revenues could be negatively impacted, which could negatively impact our results of operations and financial condition.

Our delegated underwriting program may subject our mortgage insurance business to unanticipated claims.

In our mortgage insurance business, we approve lenders to underwrite mortgage insurance applications based on our mortgage insurance underwriting guidelines. Each lender participating in the delegated underwriting program must be approved by our risk management group, and once we accept a lender into our delegated underwriting program, we allow the lenders to underwrite mortgage insurance applications based on our underwriting guidelines. While we have systems and processes to monitor whether certain aspects of our guidelines are being followed, under this program, a lender could commit us to insure a material number of loans with unacceptable risk profiles before we discover the problem and are able to terminate that lender’s delegated underwriting authority or pursue other rights that may be available to us, such as our rights to rescind coverage or deny claims.

Our mortgage insurance business faces intense competition.

The U.S. mortgage insurance industry is highly competitive. Our competitors primarily include other private mortgage insurers and governmental agencies, principally the FHA and VA.

We currently compete with other private mortgage insurers that are eligible to write business for the GSEs primarily on the basis of price, underwriting guidelines, overall service, customer relationships, perceived financial strength (including comparative credit ratings) and reputation. For more information about our competitive environment, including pricing competition, see “Item 1. Business—Competition.”

Pricing strategies continue to evolve in the mortgage insurance industry. In recent years, mortgage insurers generally have transitioned from a predominantly standard rate-card-based pricing model to the use of proprietary, “black box” pricing frameworks that use a spectrum of filed rates to allow for formulaic, risk-based pricing based on multiple loan, borrower and property attributes that may be quickly adjusted within certain parameters. The use of these granular risk-based pricing methodologies has contributed to a pricing environment that is more dynamic with more frequent pricing changes that can be implemented quickly, as well as an overall reduction in pricing transparency. As a result, we may not be aware of rate changes in the industry until we observe that our volume of NIW has changed. Further, in addition to “black box” pricing, industry pricing practices in recent years have also included an increased use of customized rate plans for certain customers, pursuant to which rates may be awarded to customers for only a limited period of time. The evolution of pricing strategies throughout the industry has resulted in greater volatility in our NIW and a reduction in industry pricing, including our pricing, due to the heightened competition inherent in the use of these pricing tools as compared to prior periods when standard rate cards were most prevalent.

Pricing has become the predominant competitive market factor for private mortgage insurance and an increasing number of customers are making their choice of mortgage insurance providers primarily based on the lowest price available for any particular loan. Our approach to pricing is customer-centric and flexible, as we offer a spectrum of risk-based pricing solutions for our customers that are designed to be balanced with our objectives for managing our volume of NIW and the risk/return profile of our insured portfolio. Although we believe we are well-positioned to compete effectively, our pricing strategy may not be successful and we may lose business to other competitors.

Increased pricing competition has lowered the premium yield of our insured portfolio over time as older vintage insured loans with higher premium rates run-off and have been replaced with insured loans with premium rates that generally have been lower. It is possible that pricing competition could further intensify, which could result in a decrease in our projected returns. Our increased use of reinsurance over the past several years has helped to mitigate the negative effect of declining premium rates on our expected returns. However, reinsurance may not always be available or available on terms attractive to us. See “Reinsurance may not be available, affordable or adequate to protect us against losses.”

We also compete with governmental entities, such as the FHA and VA, primarily on the basis of loan limits, pricing, credit guidelines, loss mitigation practices and terms of our insurance policies such as the ability to terminate private mortgage insurance, subject to conditions, as compared to the life-of-loan requirement under FHA policies. These governmental entities typically do not have the same capital requirements or business objectives that we and other private mortgage insurance companies have, and therefore, may have greater financial flexibility or different motivations with respect to pricing that could put us at a competitive disadvantage. In February 2023, the FHA announced a 0.30% reduction in its annual mortgage insurance premium for most new borrowers. This pricing change and other potential future changes in pricing by these governmental entities, or to the terms and conditions of their mortgage insurance or other credit enhancement products, could negatively impact our ability to compete in that market effectively, which could have an adverse effect on our business, financial condition and operating results. See “Item 1. Business—Regulation—Federal Regulation—Housing Finance Reform and the GSEs’ Business Practices” for further discussion of factors that could impact the FHA’s competitive position relative to private mortgage insurance.

In addition, as market conditions change, alternatives to private mortgage insurance may become more prevalent, which could reduce the demand for private mortgage insurance in its traditional form. For example, alternatives to private mortgage insurance could include: investors using risk mitigation and credit risk transfer techniques other than private mortgage

50

Part I. Item 1A. Risk Factors

insurance (or accepting credit risk without credit enhancement); lenders and other investors holding mortgages in portfolio and self-insuring; and/or lenders originating mortgages using “piggyback” structures to avoid private mortgage insurance. See “Changes in the charters, business practices or role of the GSEs in the U.S. housing finance market generally, could significantly impact our businesses” for risks related to changes in the GSEs’ business practices that could impact our competitive position, including the use of alternatives to traditional mortgage insurance to satisfy their charter requirements related to credit risk.

The competitive environment is extremely challenging given the multitude of factors discussed above. This environment, as well as potential further changes to this evolving environment, could negatively impact our franchise value, business prospects, results of operations and financial condition.

Our NIW and franchise value could decline if we lose business from significant customers.

Our mortgage insurance business depends on our relationships with our customers. Lending customers may decide to write business only with a limited number of mortgage insurers or only with certain mortgage insurers, based on their views with respect to an insurer’s pricing levels and pricing delivery methods, service levels, underwriting guidelines, loss mitigation practices, information security and other compliance programs, financial strength or other factors. Our customers place insurance with us directly on mortgage loans they originate, and they also do business with us indirectly through purchases of mortgage loans that already have our mortgage insurance coverage. Our relationships with our customers may influence both the amount of business they conduct with us directly and their willingness to continue to consider us as an approved mortgage insurance provider for loans that they purchase. For risk management purposes, our lending customers may choose to diversify the mortgage insurers with which they do business which could have a negative impact on our NIW if it results in a market share loss that we are unable to mitigate through volume from new customers or through increases in volume with existing customers.

Further, industry pricing practices in recent years have resulted in greater volatility in the volume we may receive from any particular customer as we may retain, gain or lose customers’ loan volume based solely on the competitiveness of our pricing levels, regardless of other factors such as service levels, underwriting guidelines, loss mitigation practices or financial strength. See “Our mortgage insurance business faces intense competition.”

Finally, we currently offer and may offer in the future products that could be viewed as competitive to products offered by certain of our customers, which could influence a customer’s decision as to whether to do business with us. Loss of a significant customer could result in a loss of market share and negatively impact our results of operations and financial condition.

The current financial strength ratings assigned to our mortgage insurance subsidiaries could weaken our competitive position and potential downgrades by rating agencies to these ratings and the ratings assigned to Radian Group could adversely affect the Company.

Radian Guaranty has been assigned a rating of A3 by Moody’s Investors Service (“Moody’s”), a rating of A- by S&P Global Ratings (“S&P”) and a rating of A- by Fitch Ratings, Inc. (“Fitch”). Radian Group has been assigned a rating of Baa3 by Moody’s, BBB- by S&P and BBB- by Fitch.

We do not believe our ratings have a material effect on our relationships with existing customers currently. However, if financial strength ratings become a more prominent consideration for lenders, we may be competitively disadvantaged by customers choosing to do business with private mortgage insurers that have higher financial strength ratings. In addition, while the current PMIERs do not include a specific ratings requirement with respect to eligibility, failure to maintain a rating for Radian Guaranty that is acceptable to the GSEs could impact Radian Guaranty’s eligibility status under the PMIERs. Further, a downgrade in our financial strength ratings could result in increased scrutiny of our financial condition by the GSEs and/or our customers, potentially resulting in a decrease in the amount of our NIW.

We believe that financial strength ratings would represent a significant consideration for participants should they seek to secure credit enhancement in the non-GSE mortgage market, which includes most non-QM loans. If the non-GSE market once again becomes receptive to the benefits of private mortgage insurance, our ability to successfully insure loans in this market could depend on our ability to secure higher ratings for our mortgage insurance subsidiaries. In addition, if legislative or regulatory changes were to alter the current state of the housing finance industry such that the GSEs no longer operate in their current capacity, we may be forced to compete in a new marketplace in which financial strength ratings may play a greater role.

The rating agencies continually review the financial strength ratings assigned to Radian Group and its mortgage insurance subsidiaries, and the ratings are subject to change. Financial strength ratings are important to maintaining confidence in our mortgage insurance and in our competitive position. Downgrades to the ratings of our mortgage insurance subsidiaries and/or Radian Group could adversely affect our cost of funds, liquidity, access to capital markets and competitive position. A downgrade in Radian Guaranty’s financial strength rating could result in increased scrutiny by the GSEs and our customers, potentially impacting our NIW. If we are unable to compete effectively in the current or any future markets as a result of the financial strength ratings assigned to our mortgage insurance subsidiaries, the franchise value and future prospects for our mortgage insurance business could be negatively affected.

51

Part I. Item 1A. Risk Factors

Our business depends, in part, on effective and reliable loan servicing.

We depend on third-party servicing of the loans that we insure. Dependable servicing is necessary for timely billing and premium payments to us and effective loss mitigation opportunities for delinquent or near-delinquent mortgage loans. Servicers are required to comply with a multitude of legal and regulatory requirements, procedures and standards for servicing residential mortgages, such as the CFPB’s mortgage servicing rules. While these requirements are intended to ensure a high level of servicing performance, they also impose a high cost of compliance on servicers that may impact their financial condition and their operating effectiveness. For example, the various servicing-related requirements imposed by the CARES Act, the GSEs, the FHA, CFPB and other federal and state governmental and regulatory bodies and agencies to address the impact of the COVID-19 pandemic on mortgage borrowers heightened the burdens placed on servicers.

While servicing standards and processes have strengthened since the great financial crisis in 2008, challenging economic and market conditions or periods of economic stress and high mortgage defaults make it more difficult for servicers to effectively service the mortgage loans that we insure, which could reduce their loss mitigation efforts that could help limit our losses. Further, an increase in delinquent loans may result in liquidity issues for servicers. When a mortgage loan that is collateral for a mortgage-backed security becomes delinquent, the servicer is usually required to continue to pay principal and interest to the RMBS investors, generally for four months, even though the servicer is not receiving payments from borrowers. This may cause liquidity issues, especially for non-bank servicers because they do not have the same sources of liquidity that bank servicers have. A transfer of servicing resulting from liquidity issues, may increase the operational burden on servicers, cause a disruption in the servicing of delinquent loans and reduce servicers’ abilities to undertake loss mitigation efforts that could help limit our losses.

Information with respect to the mortgage loans we insure is based in large part on information reported to us by third parties, including the servicers and originators of the mortgage loans, and information provided may be subject to lapses or inaccuracies in reporting from such third parties. In many cases, we may not be aware that information reported to us is incorrect until such time as a claim is made against us under the relevant insurance policy. We may not receive monthly information from servicers for single premium policies, and may not be aware that the mortgage loans insured by such policies have been repaid. We periodically attempt to determine if coverage is still in force on such policies by asking the last servicer of record or through the periodic reconciliation of loan information with certain servicers. It may be possible that our reports continue to reflect, as active, policies on mortgage loans that have been repaid. If we experience a disruption in the servicing of mortgage loans covered by our insurance policies or a failure by servicers to appropriately report the status of a loan, this could impact the amount of assets Radian Guaranty is required to hold under the PMIERs or ultimately contribute to a rise in claims among those loans, which could negatively impact our business, financial condition and operating results.

Under the terms of our Master Policies in place since 2014, mortgage insurance premiums are not required to be paid following an event of default. However, if a defaulted loan then cures and becomes current, all mortgage insurance premiums must also be brought current for our insurance coverage to continue, including all premiums that were not paid during the period following the event of default and through the date of cure. Because premiums must be brought current upon a cure, mortgage servicers typically continue to pay mortgage insurance premiums while loans remain in default, understanding that Radian Guaranty will refund these premiums if the loans fail to cure and ultimately go to claim. If we fail to receive mortgage insurance premiums following mortgage defaults, Radian Guaranty’s cash flow could be materially reduced, potentially requiring Radian Guaranty to liquidate investments at a loss to pay future claims or otherwise requiring us to alter our investment strategy.

We face risks associated with our contract underwriting business.

We provide third-party contract underwriting services for our mortgage insurance customers. Generally, we offer limited indemnification to our contract underwriting customers. In addition to indemnification, we typically have limited loss mitigation defenses available to us for loans that we have underwritten through our contract underwriting services. As a consequence, our results of operations could be negatively impacted if we are required to indemnify our customers for material underwriting errors in our contract underwriting services.

A decrease in the volume of mortgage originations could result in fewer opportunities for us to write new mortgage insurance business and conduct our homegenius businesses.

The amount of new mortgage insurance business we write and real estate transactions we support through our homegenius business depends, among other things, on a steady flow of low down payment mortgages that require private mortgage insurance and on the volume of real estate transactions that benefit from our services or products. The volume of mortgage originations is impacted by macroeconomic conditions and specific events that impact the housing finance and real estate markets, most of which are beyond our control, including housing prices, inflationary pressures, unemployment levels, interest rate changes, the availability of credit, other national and regional economic conditions and geopolitical events. In “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” see “Overview—Current Operating Environment” and “Key Factors Affecting Our Results—Mortgage Insurance.” Factors affecting the volume of low down payment mortgages include:

■the health and stability of the financial services industry;

52

Part I. Item 1A. Risk Factors

■restrictions on mortgage credit due to changes in lender underwriting standards, capital requirements affecting lenders, regulatory requirements and the health of the private securitization market;

■mortgage interest rates;

■the health of the domestic economy generally, including in particular unemployment levels and the degree of consumer confidence, as well as specific conditions in regional and local economies;

■housing supply and affordability;

■tax laws and policies and their impact on, among other things, deductions for mortgage insurance premiums, mortgage interest payments and real estate taxes;

■demographic trends, including the rate of household formation;

■the rate of home price appreciation;

■government housing policy encouraging affordability and accessibility of mortgage loans, in particular to first-time homebuyers; and

■the practices of the GSEs, including the extent to which the guaranty fees, loan level price adjustments, credit underwriting guidelines and other business terms provided by the GSEs affect the cost of mortgages and lenders’ willingness to extend credit for low down payment mortgages.

As the overall volume of new mortgage originations declines, we are subject to increased competition and we could experience a reduced opportunity to write new insurance business and provide our homegenius products and services, which could negatively affect our business prospects, results of operations and financial condition.

We are exposed to risks associated with our homegenius businesses that could negatively affect our results of operations and financial condition.

Our homegenius businesses expose us to certain risks that may negatively affect our results of operations and financial condition, including, among others, the following:

■Our homegenius businesses are heavily focused on digital products and services, including proprietary platforms as a service solutions, that depend on our ability to develop, launch and implement new and innovative technologies and digital solutions. As a result, this business is particularly exposed to: challenges associated with new and rapidly evolving technologies and business environments; the long sales cycle associated with, and customer acceptance of, our digital product and service offerings; the costs associated with the development and launch of these technologies and products; our ability to successfully integrate new technologies into our existing systems; and the risk that our digital product and services offerings fail to operate as expected or planned or expose us to additional cybersecurity or third-party risks;

■Our homegenius businesses depend on our relationships with our customers. Our homegenius revenue currently is dependent on a limited number of large customers that represent a significant proportion of our homegenius total revenues. The loss or reduction of business from one or more of these significant customers could adversely affect the level of our homegenius revenues. In addition, Radian Guaranty does business with many of these significant customers. In the event of a dispute between a significant customer and either of our business segments, the overall customer relationship for Radian could be negatively impacted;

■Due to the transactional nature of our business, our homegenius segment revenues are subject to fluctuation from period to period and are difficult to predict;

■The services we offer through our homegenius businesses are influenced by the level of overall activity in the mortgage, real estate and mortgage finance markets generally. When real estate transaction volumes decline, as occurred during 2023, we are likely to experience less demand for our real estate and title services;

■homegenius Real Estate is a licensed real estate brokerage and provides real estate brokerage services in all 50 states and the District of Columbia. As a licensed real estate brokerage, homegenius Real Estate receives residential real estate information from various multiple listing services. homegenius Real Estate receives this information, which it uses in its business to provide real estate services (e.g., home search and brokering real estate transactions) and provide valuation products and services that comprise many of our homegenius product offerings, pursuant to the terms of agreements with the multiple listing service (“MLS”) providers. If these agreements were to terminate or homegenius Real Estate otherwise were to lose access to this information, it could negatively impact homegenius Real Estate’s ability to conduct its business and our future real estate strategies. In addition to MLS data, we depend on access to data from a variety of other external sources to maintain our databases and grow our businesses. If we were to lose access to one or more of these data sources, the quality, pricing and availability of our homegenius products and services may be negatively impacted;

■By their nature, title claims are often complex, vary greatly in dollar amounts and are affected by economic and market conditions and the legal environment existing at the time of settlement of the claims. Estimating future title loss payments is difficult because of the complex nature of title claims, the long periods of time over which claims are administered and paid, significantly varying dollar amounts of individual claims and other factors. From time to time, we could experience

53

Part I. Item 1A. Risk Factors

large losses or an overall worsening of our loss payment experience in regard to the frequency or severity of claims that require us to record additional charges to our claims loss reserve. These loss events are unpredictable and may require us to increase our title loss reserves and could adversely affect the financial performance of our homegenius segment; and

■Our homegenius businesses operate in a highly competitive environment. Our competitors vary in size and in the scope and breadth of the services they offer, and many have substantial resources. We expect that the markets in which we compete will continue to attract new competitors, technologies and products that are designed to disrupt traditional business models. There can be no assurance that our homegenius businesses will be able to compete successfully.

Any of these factors could negatively affect our homegenius businesses and could have a material adverse effect on our results of operations and financial condition.

We rely upon proprietary technology and information, and if we are unable to protect our intellectual property rights, it could have a material adverse effect on us.

Our success depends, in part, upon our intellectual property rights. We rely primarily on a combination of copyrights, trade secrets, trademarks, nondisclosure and other contractual restrictions on copying, distributing and creating derivative products to protect our proprietary technology and information. This protection is limited, and our intellectual property could be used by others without our consent. In addition, although we have patents pending and may file future patent applications, patents may not be issued, and, if issued may not prevent the development of competitive products. Any infringement, disclosure, loss, invalidity of or failure to protect our intellectual property could have a material adverse effect on our business, financial condition and results of operations. Moreover, litigation may be necessary to enforce or protect our intellectual property rights, to protect our trade secrets or to determine the validity and scope of the proprietary rights of others. Such litigation could be time-consuming, result in substantial costs and diversion of resources and could have a material adverse effect on our business, financial condition and results of operations.

We face risks associated with our mortgage conduit business.

Our mortgage conduit business is conducted through Radian Mortgage Capital, which acquires and aggregates residential mortgage loans with the intention of then selling the loans directly to mortgage investors or distributing them into the capital markets through private label securitizations. To date, Radian Mortgage Capital has only executed the distribution of loans through sales to mortgage investors. Subject to market conditions, Radian Mortgage Capital also expects to distribute the loans into the capital markets through private label securitizations in the future. Radian Mortgage Capital finances its acquisition of residential mortgage loans primarily by utilizing short-term uncommitted debt under the Master Repurchase Agreements. Radian Mortgage Capital is the master servicer for the loans it acquires and has engaged a subservicer to manage the day-to-day servicing operations for its acquired mortgage loan portfolio. As a result of our mortgage conduit business, we are exposed to certain risks that may negatively affect our results of operations and financial condition, including, among others, the following:

■Potential breaches of the financial and other covenants under our Master Repurchase Agreements could result in our being required to immediately repay all outstanding amounts borrowed under these facilities and these facilities being unavailable to use for future financing needs, as well as potentially triggering cross-defaults under other debt agreements.

■Interest rate fluctuations can negatively impact our mortgage conduit business.

▪Changes in interest rates and other factors could cause the cost of financing a mortgage asset to exceed the income generated by that mortgage asset. An increase in interest rates generally increases the overall cost to finance our acquisitions of mortgage loans and reduces the fair value of mortgage loans pledged as collateral for our payment obligations.

▪We have an interest rate risk hedging program and seek to hedge interest rate risks associated with our acquisition and temporary retention of mortgage assets; however, changes in interest rates, securities spreads and other factors could cause net losses on the mortgage assets and our hedge position. Given the uncertainty of future market conditions, there can be no assurance that our hedging activity will be fully effective.

■Under our Master Repurchase Agreements we pledge mortgage assets as security for our payment obligations, and these agreements contain margin requirements that require us to pledge additional collateral if the value of previously pledged collateral declines below certain levels. Therefore, if the value of the collateral decreases below certain levels, we could be required to satisfy a margin call under the Master Repurchase Agreements. In addition, certain of our hedges are also subject to margin calls. As the conduit business grows, any of these margin calls could have a material adverse effect on Radian Mortgage Capital’s liquidity position and could require Radian Group to satisfy the margin requirements pursuant to its guarantee of Radian Mortgage Capital’s obligations under the Master Repurchase Agreements or through capital contributions to Radian Mortgage Capital, which could impact Radian Group’s available liquidity. See “Our sources of liquidity may be insufficient to fund our obligations.”

■If the secondary markets for mortgages or for residential mortgage-backed securities experiences any significant disruption or illiquidity, we might be unable to sell our mortgage assets in a timely manner or at anticipated prices, and we

54

Part I. Item 1A. Risk Factors

may be forced to hold and finance a larger inventory of mortgage assets than we anticipate, which could have a material adverse effect on our business, financial condition, liquidity and results of operations.

■Because we do not originate residential loans, the growth of our mortgage conduit business may be limited if mortgage loans generally are not available for purchase. Mortgage loan originations fluctuate from period to period, and a reduced volume of loan originations that satisfy our acquisition guidelines may make it difficult for us to acquire loans.

■When we purchase mortgage loans, representations and warranties are made to us by sellers regarding, among other things, certain characteristics of those mortgage loans, which we seek to verify through underwriting and due diligence. When we sell mortgage loans, we make similar representations and warranties to purchasers. Losses could result if representations or warranties we make to purchasers are inaccurate, including representations or warranties made in reliance on inaccurate representations or warranties that are made to us.

■We rely on a third-party service provider to service the mortgage loans for which we hold the right to service and serve as the master servicer. Our reliance on this third-party servicer exposes us to certain risks, including the risk that the subservicer may not properly service the loan in compliance with applicable laws and regulations or the contractual provisions governing their subservicing role, in which case we may be held liable for the subservicer’s improper acts or omissions. Failure to take steps to ensure that third-party servicers are servicing the loans we acquire appropriately could expose us to penalties or other claims or enforcement actions that could negatively impact our business prospects, results of operations and financial condition.

■Under the Investment Company Act of 1940, an investment company is required to register with the SEC and is subject to extensive restrictive regulations relating to, among other things, operating methods, management, capital structure, dividends, and transactions with affiliates. We intend to conduct our businesses and operations so that Radian Mortgage Capital is not required to register as an investment company under the Investment Company Act of 1940. Failure to continue to qualify for exemption from the Investment Company Act of 1940 could result in significant restrictions on our business activities, prohibitions from engaging in certain business activities and subject us to burdensome compliance requirements and have a material adverse effect on our business prospects, results of operations and financial condition.

If the models used in our businesses are inaccurate, it could have a material adverse impact on our business, results of operations and financial condition.

We employ proprietary and third-party models for a wide range of purposes, including, among others, the following: projecting losses, premiums, expenses, and returns; pricing products; estimating reserves; evaluating risk; determining internal capital requirements; and performing stress testing. These models rely on estimates, projections and assumptions that are inherently uncertain and may not always operate as intended. This can be especially true when extraordinary events occur such as periods of extreme inflation, pandemics, or environmental disasters related to changing climatic conditions. In addition, our models are being continuously updated over time. Changes in models or model assumptions could lead to material changes in our future expectations, returns, or financial results. The models we employ are complex, which could increase our risk of error in their design, implementation, or use. Also, the associated data, assumptions and calculations that we input into our models may not always be correct or accurate and the controls we have in place to mitigate these risks may not be effective in all cases. The risks related to our models may increase when we change assumptions, methodologies, or modeling platforms. Moreover, we may use information we receive through enhancements to refine or otherwise change existing assumptions and/or methodologies.

Actual or perceived instability in the financial services industry or non-performance by financial institutions or transactional counterparties could materially impact our business.

We routinely execute transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, reinsurers, and our customers. Many of these transactions expose us to credit risk and losses in the event of a default by a counterparty or customer. Any such losses could have a material adverse effect on our financial condition and results of operations.

Limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry with which we do business, or concerns or rumors about the possibility of such events, have in the past and may in the future lead to market-wide liquidity problems. Such conditions may negatively impact our results and/or financial condition. While we are unable to predict the full impact of these conditions, they may lead to among other things: disruption to the mortgage market, delayed access to deposits or other financial assets; losses of deposits in excess of federally-insured levels; reduced access to, or increased costs associated with, funding sources and other credit arrangements adequate to finance our current or future operations; increased regulatory pressure; the inability of our counterparties and/or customers to meet their obligations to us; economic downturn; and rising unemployment levels.

Part I. Item 1A. Risk Factors

Risks Related to the Economic Environment

The credit performance of our mortgage insurance portfolio is impacted by macroeconomic conditions and specific events that affect the ability of borrowers to pay their mortgages.

Mortgage defaults occur due to a variety of specific events affecting individual borrowers, including death or illness, divorce or other family-related factors and unemployment, among other events. While mortgage defaults can and do occur in any economic environment, there is a high correlation between the overall health of the economy and the performance of our mortgage insurance portfolio. As a result, our results are particularly influenced by macroeconomic conditions and specific events that impact the housing finance and real estate markets, including events that impact mortgage originations and the credit performance of our mortgage insurance portfolio, most of which are beyond our control, including housing prices, inflationary pressures, unemployment levels, interest rate changes, the availability of credit and other national and regional economic conditions. These conditions may be created or exacerbated by: acts of terrorism, war or other geopolitical conditions and conflicts; event-specific economic depressions; U.S. debt ceiling and budget deficit concerns; severe weather events and natural disasters, which may continue to increase in severity and frequency due to climate change; and other catastrophic events such as pandemics or epidemics. In general, challenging economic conditions increase the likelihood that borrowers will not have sufficient income to satisfy their mortgage obligations.

A decline in home prices can occur due to deteriorating economic conditions or other factors that reduce the demand for homes, such as changes in buyers’ perceptions of the potential for future home price appreciation, restrictions on and the cost of mortgage credit due to more stringent underwriting standards, higher interest rates, changes to the tax deductibility of mortgage interest, decreases in the rate of household formations, or other factors. Declining housing values can influence the willingness of borrowers to continue to make mortgage payments despite having the financial resources to do so. A decline in home values typically makes it more difficult for borrowers to sell or refinance their homes, increasing the likelihood that a default will result in a claim. Declining housing values also may impact the effectiveness of our loss mitigation actions. The amount of the loss we could suffer depends in part on whether the home of a borrower who defaults on a mortgage can be sold for an amount that will cover the unpaid principal balance, interest and the expenses of the sale. Any of these events may have a material adverse effect on our business, results of operations and financial condition.

Currently, inflation and interest rates in the U.S. continue to be elevated, although inflation has moderated from its 40-year high in 2022 and interest rates have decreased from their recent peak in the latter part of 2023. In addition to these macroeconomic conditions, future volatility may occur due to, among other factors, declining home prices, the risk of higher unemployment rates and political conditions. Unfavorable macroeconomic developments and the other factors cited above have had in the past, and in the future may have again, a material negative impact on our results of operations and financial condition.

Our success depends, in part, on our ability to manage risks in our investment portfolio.

Our investment portfolio is an important source of revenue and is our primary source of claims paying resources. Although our investment portfolio consists primarily of highly-rated fixed income investments, we may not achieve our investment objectives because our investment strategy is affected by factors beyond our control, such as general macroeconomic conditions, geopolitical events, domestic political conditions and tax policies, which may adversely affect the markets for credit and interest-rate-sensitive securities, including the extent and timing of investor participation in these markets, the level and volatility of interest rates and credit spreads and, consequently, the value of our fixed income securities and the level of our net investment income.

Volatility or lack of liquidity in the markets in which we invest has at times reduced the market value of some of our investments, including as a result of the disruption in the financial markets following the onset of the COVID-19 pandemic and more recently, inflationary and interest rate trends and actual or perceived instability in the financial services industry. The value of our investment portfolio is subject to market risk and may be adversely affected by other factors outside of our control, such as ratings downgrades, bankruptcies and credit spreads widening, any of which may cause unrealized or realized losses. When the credit environment deteriorates, the risk of impairments of our investments increases. Disruption and volatility in the financial markets, including the sharp increases in market interest rates we experienced in 2022 and 2023, could also have a material adverse effect on our liquidity, financial condition and results of operations. See “Our reported earnings, stockholders’ equity and book value per share are subject to fluctuations based on changes in our investments that require us to adjust their fair market value.”

Many of our investment securities are issued by the U.S. government and government agencies and sponsored entities. As a result of uncertain domestic political conditions, potential political instability or the perceived inability of the U.S. government to legislate on matters in a timely fashion, there is the threat that potential future federal government shutdowns or the possibility of the federal government defaulting on its obligations for a short period of time due to debt ceiling limitations or other issues could pose general credit and liquidity risks for investments in financial instruments issued or guaranteed by the federal government. Any potential downgrades by rating agencies in long-term sovereign credit ratings, as well as sovereign debt issues facing the governments of other countries, could have a material adverse impact on financial markets and economic conditions worldwide.

56

Part I. Item 1A. Risk Factors

For the significant portion of our investment portfolio held by our insurance subsidiaries, to receive favorable treatment under insurance regulatory requirements and full credit as Available Assets under the PMIERs, we generally are limited to investing in investment grade fixed income investments with yields that reflect their lower credit risk profile. Because we depend on our investments as a source of revenue, a prolonged period of lower than expected investment yields has an adverse impact on our revenues and could adversely affect our results of operations. Further, future updates to the insurance regulatory requirements or the PMIERs could restrict our investment choices, which could negatively impact our investment strategy.

In addition, we structure the maturities of investments in our investment portfolio to satisfy our expected liabilities, including claim payments in our mortgage insurance business. If we underestimate our future claim payments or other liabilities or improperly structure our investments to meet these liabilities, we could have unexpected losses resulting from the forced liquidation of investments before their maturity, which could adversely affect our results of operations.

Climate change and extreme weather events could adversely affect our businesses, results of operations and financial condition.

Our businesses, results of operations and financial performance could be adversely impacted by climate change and extreme weather events, especially if these occurrences negatively impact the overall real estate market and the broader economy. Climate change may increase the frequency and severity of natural disasters such as hurricanes, tornadoes, floods and forest fires and drive other ecologically related changes such as rising sea waters, which in turn could negatively affect regional economies in ways that impact home values or unemployment, and therefore, the credit performance of the mortgages we insure in affected areas. In addition, the inability of a borrower to obtain hazard and/or flood insurance, or the increased cost of such insurance, could lead to an increase in delinquencies or a decrease in home prices in the affected areas. If we were to attempt to limit our new insurance written in affected areas, lenders may choose not to do business with us. Natural disasters could also lead to increased reinsurance rates or reduced availability of reinsurance. This may cause us to retain more risk than we otherwise would retain and could negatively affect our compliance with financial requirements.

The FHFA has previously instructed the GSEs to designate climate change as a priority concern and actively consider its effects in their decision making. More recently, including as part of the 2024 GSE Scorecard, the FHFA has instructed the GSEs to explore the affordability and availability of property insurance to identify opportunities to mitigate risk while furthering sustainable homeownership. It is uncertain whether these efforts will result in any GSE guideline or mortgage insurance policy changes that could materially impact the volume and characteristics of our NIW (including the terms of our Master Policy), home prices in certain areas and defaults by borrowers in certain areas.

Further, climate change and natural disasters may impact the value of and cause volatility in our investment portfolio, and we might not achieve our investment objectives. Climate change and the frequency, severity, duration, and geography of severe weather events and other ecological-related changes are inherently uncertain, and we cannot predict the ultimate impact these events may have on our business and financial condition.

Our reported earnings, stockholders’ equity and book value per share are subject to fluctuations based on changes in our investments that require us to adjust their fair market value.

We have holdings of trading securities, equity securities, mortgage loans held for sale and short-term investments that we carry at fair value. Because the changes in fair value of these financial instruments are reflected on our statements of operations each period, they affect our reported earnings and can create earnings volatility. In addition, we increase or decrease our stockholders’ equity by the amount of change in the unrealized gain or loss (the difference between the fair value and the amortized cost) of our available for sale securities portfolio, net of related tax, under the category of accumulated other comprehensive income (loss). As a result, a decline in the fair value of our available for sale portfolio may result in a decline in reported stockholders’ equity, as well as book value per common share. Among other factors, interest rate changes, market volatility and declines in the value of underlying collateral will impact the value of our investments, potentially resulting in unrealized losses that could negatively impact our results of operations and stockholders’ equity. These negative impacts will occur even though the securities are not sold. Also, in the event there are credit loss-related impairments, the credit loss component and subsequent recoveries, if any, are recognized in earnings.

Risks Related to Liquidity and Financing

Our sources of liquidity may be insufficient to fund our obligations.

Radian Group serves as the holding company for our operating subsidiaries and does not have any operations of its own. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Liquidity Analysis—Holding Company” for more information on our available liquidity and short-term and long-term liquidity demands.

As discussed above under “Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity,” compliance with the PMIERs financial requirements could impact our holding company liquidity if additional capital support for Radian Guaranty is required

57

Part I. Item 1A. Risk Factors

for it to maintain this compliance. The amount of capital that Radian Group could be required to contribute to Radian Guaranty for this purpose is uncertain but could be significant.

In addition, Radian Mortgage Capital has entered into the Master Repurchase Agreements to finance its acquisition of residential mortgage loans, and Radian Group has guaranteed the obligations of certain of its subsidiaries under these loan repurchase facilities. As discussed above under “We face risks associated with our mortgage conduit business,” a decline in the value of collateral pledged under these agreements and our hedging agreements could trigger a margin call and require Radian Mortgage Capital to pledge additional collateral under these arrangements, which Radian Mortgage Capital may be unable to satisfy without a capital contribution from Radian Group. Any capital contribution could be significant in amount as this business grows.

In addition to available cash and marketable securities, Radian Group’s most significant near-term sources of cash to fund future liquidity needs include: (i) payments made to Radian Group by its subsidiaries under expense- and tax-sharing arrangements; (ii) net investment income earned on its cash and marketable securities; and (iii) to the extent available, dividends or other distributions from its subsidiaries. See Note 16 of Notes to Consolidated Financial Statements for additional information on Radian Guaranty’s ability to pay dividends.

Radian Group’s expense-sharing arrangements with its principal operating subsidiaries require those subsidiaries to pay their allocated share of certain holding-company-level expenses, including interest payments on Radian Group’s outstanding senior notes. The expense-sharing arrangements between Radian Group and our mortgage insurance subsidiaries, as amended, have been approved by the Pennsylvania Insurance Department, but such approval may be modified or revoked at any time.

In light of Radian Group’s short- and long-term needs, it is possible that our sources of liquidity could be insufficient to fund its obligations. If this were to occur, we may choose not to pursue certain actions, such as issuing dividends or repurchasing shares of our common stock, or we may elect to reduce the levels of these activities to preserve our available liquidity. In addition, we may seek to increase our available liquidity, including by seeking additional capital, incurring additional debt, issuing additional equity, or selling assets, which we may be unable to do on favorable terms, if at all.

Our revolving credit facility and the Parent Guarantees we provide for the Master Repurchase Agreements to finance loan purchases in our mortgage conduit business contain covenants that are restrictive and could limit our operating flexibility. A default under our credit facility or these Parent Guarantees could trigger an event of default under the terms of our senior notes. We may not have access to funding under our credit facility when we require it.

Radian Group is a party to a $275 million unsecured revolving credit facility with a syndicate of bank lenders. As of December 31, 2023, no borrowings were outstanding under the credit facility.

The credit facility contains customary representations, warranties, covenants, terms and conditions. Our ability to borrow under the credit facility is conditioned on the satisfaction of certain financial and other negative and affirmative covenants, including covenants related to minimum net worth and statutory capital, a maximum debt-to-capitalization level, repayment or refinancing of our senior notes at or prior to their maturity, and limitations on our ability to incur additional indebtedness, make investments, create liens, transfer or dispose of assets and merge with or acquire other companies. The credit facility also requires that Radian Guaranty remain eligible under the PMIERs to insure loans purchased by the GSEs. A failure to comply with these covenants or the other terms of the credit facility could result in an event of default, which could: (i) result in the termination of the commitments by the lenders to make loans to Radian Group under the credit facility and (ii) enable the lenders to declare, subject to the terms and conditions of the credit facility, any outstanding obligations under the credit facility to be immediately due and payable.

Further, the occurrence of an event of default under the terms of our credit facility may trigger an event of default under the terms of our senior notes. An event of default would occur under the terms of our senior notes if a default: (i) in any scheduled payment of principal of other indebtedness by Radian Group or its subsidiaries of more than $100 million principal amount occurs, after giving effect to any applicable grace period or (ii) in the performance of any term or provision of any indebtedness of Radian Group or its subsidiaries in excess of $100 million principal amount occurs that results in the acceleration of the date such indebtedness is due and payable, subject to certain limited exceptions. See Note 12 of Notes to Consolidated Financial Statements for more information on the carrying value of our senior notes.

In connection with our mortgage conduit, Radian Group has entered into the Parent Guarantees that guarantee the obligations of certain of its subsidiaries pursuant to the Master Repurchase Agreements. Under these Parent Guarantees, Radian Group is subject to negative and affirmative covenants customary for this type of financing transaction, including compliance with financial covenants that are generally consistent with the comparable covenants in the Company’s revolving credit facility, as discussed above.

If we are unable to satisfy certain covenants or representations or experience an event of default under the credit facility or the Parent Guarantees, we may not have access to funding in a timely manner, or at all, when we require it. If funding is not available when we require it, our ability to continue our business practices and operations, or pursue our current strategy, could be limited. If the indebtedness under the credit facility, the guarantees or our senior notes is accelerated, we may not be able to repay our debt or borrow sufficient funds to refinance it.

58

Part I. Item 1A. Risk Factors

Risks Related to Information Technology and Cybersecurity

Our information technology systems may fail or become outmoded, be temporarily interrupted or otherwise cause us to be unable to meet our customers’ demands.

Our business is highly dependent on the effective operation of our information technology systems, which are vulnerable to damage or interruption from power outages, computer and telecommunications failures, computer viruses, cyberattacks and security incidents or breaches, catastrophic events and errors in usage. Although we have disaster recovery and business continuity plans in place, we may not be able to adequately execute these plans in a timely fashion. Further, as various systems, technologies, software and applications become outdated or new technology is required, including as a result of end-of-life or end-of-support, we may not be able to replace or introduce them as quickly as needed or in a cost-effective and timely manner.

Our customers generally require that we provide an increasing number of our products and services electronically and, as such, we are dependent on e-commerce and other technologies to deliver our products and services. Our ability to meet the needs of our customers depends on our ability to keep pace with technological advances and to invest in new technology as it becomes available or to otherwise upgrade our technological capabilities. Accordingly, we may not satisfy our customers’ requirements if we fail to invest sufficient resources or are otherwise unable to maintain and upgrade our technological capabilities. Further, customers may choose to do business only with business partners with which they are technologically compatible and may choose to retain existing relationships with mortgage insurance or mortgage and real estate services providers rather than invest the time and resources to on-board new providers. As a result, technology can represent a potential barrier to signing new customers. We are also dependent on our ongoing relationships with key technology providers, including their products and technologies, and their ability to support those products and technologies. The inability of these providers to successfully provide and support those products could have an adverse impact on our business and results of operations.

Because we rely on our information technology systems for many critical functions, including connecting with our customers, if such systems were to fail, experience a prolonged interruption or become outmoded, we may experience a significant disruption in our operations and in the business we receive, which could have a material adverse effect on our business, reputation and future prospects, financial condition and operating results.

We could incur significant liability or reputational harm if the security of our information technology systems, or of our third-party vendors or service providers, is breached, including as result of a cyberattack, or we otherwise fail to protect confidential information, including personally identifiable information that we maintain.

We rely on information technology systems to process, transmit, store and protect the electronic information, financial data and proprietary models that are critical to our business. Furthermore, a significant portion of the communications and business transmissions between us and our employees, customers, business partners and service providers depends on information technology and electronic information exchange.

Our transition to a hybrid work environment has further increased our reliance on information technology and our exposure to the risk of cybersecurity threats and data security incidents.

Our information technology systems may be vulnerable to physical or electronic intrusions. We experience cyber activity directed at our computer systems, software, networks and network users on a daily basis. This malicious activity includes attempts at unauthorized access, implantation of computer viruses or malware and denial-of-service attacks that are intended to lead to interruptions and delays in our service and operations, as well as loss, misuse or theft of personal information and other data, confidential information or intellectual property. In addition, on a global scale, other forms of social engineering and insider threats designed to obtain confidential information, destroy data, disrupt or degrade service, sabotage systems or to cause other damage have also grown in volume and level of sophistication. Such attacks may also increase in response to actions taken by the U.S. in response to geopolitical events, including the conflicts between Russia and Ukraine and the Israeli-Hamas war. The risks of cyberattacks and information security incidents and breaches continue to increase in businesses such as ours due to, among other things, the proliferation of new technologies and the use of digital channels to conduct our business, including connectivity with customer devices that are beyond our security control systems and the use of portable computers or mobile devices which can be stolen, lost or damaged. We expect attacks to continue accelerating in both frequency and sophistication with increasing use by actors of tools and techniques that could hinder our ability to identify, investigate and recover from incidents.

We also rely on numerous third-party service providers to conduct important aspects of our business operations, and we face similar risks relating to them. While we regularly conduct security assessments on these third-party vendors, we cannot be certain that their information security protocols are sufficient to withstand a cyberattack or other security breach. We also cannot be certain that we will receive timely notification of such cyberattacks or other security breaches. In addition, in order to access our products and services, our clients may use computers and other devices that are beyond our security control systems.

We and many of the third parties we work with rely on open-source software and libraries that are integrated into a variety of applications, tools and systems, which may increase our exposure to vulnerabilities. Additionally, outside parties may

59

Part I. Item 1A. Risk Factors

use social engineering or fraudulent communications to employees, vendors, partners, or users to try and obtain sensitive or confidential information in order to gain access to data. Any attempt by bad actors to obtain our data or intellectual property, disrupt our service, or otherwise access our systems, or those of third parties we use, if successful, could harm our business, be expensive to remedy and damage our reputation.

As part of our business, we, and certain subsidiaries, affiliates, and third-party vendors maintain large amounts of confidential information, including personally identifiable information on borrowers, consumers and our employees. As a result, we are subject to numerous laws and regulations designed to protect this information, such as U.S. federal and state laws governing the protection of personally identifiable information, and to significant contractual commitments with our customers. These laws and regulations are increasing in complexity and number and the contractual commitments are increasing in requirements and in demands on our businesses. If the security of our information technology or the technology of our third-party vendors is breached, including as a result of a cyberattack, it could result in the loss or misuse of this information, which could, in turn, result in potential regulatory actions or litigation, including material claims for damages, as well as interruption to our operations and damage to our customer relationships and reputation. While we have information security policies, controls and systems in place in order to attempt to prevent, detect and respond to unauthorized use or disclosure of confidential information, including personally identifiable information, there can be no assurance that such unauthorized use or disclosure will not occur either through the actions of third parties or our employees. Any cybersecurity event or other compromise of the security of our information technology systems, or unauthorized use or disclosure of confidential information, could subject us to liability, regulatory scrutiny and action, damage our reputation and negatively affect our ability to attract and maintain customers, and could have a material adverse effect on our business prospects, financial condition and results of operations.

We use statistical models, including artificial intelligence and machine learning models, to assist our decision making in key areas, such as underwriting, claims and pricing, but actual results could differ materially from the model outputs and related analyses.

We use various modeling and advanced learning techniques along with data analytics to analyze and estimate loss trends and other risks associated with our underwriting and claims operations. We use the modeled outputs and related analyses to assist us in certain decisions involving underwriting, pricing, claims, reserving and risk distribution. Our modeled outputs and related analyses may contain inaccuracies which could adversely affect our businesses. As with many technological innovations, artificial intelligence (‘’AI”) and machine learning present risks and challenges that could affect their adoption as well as our business. The assumptions used in deriving modeled outputs and related analyses are subject to risks and uncertainties, including, limitations of historical internal and industry data as well as increased risks associated with intellectual property infringement or misappropriation, data privacy and operational risks. Additionally, in general, AI algorithms may be flawed and datasets underlying AI algorithms may be insufficient or may contain biased information. If our use of AI, machine learning and statistical models produce analyses or recommendations that are or are alleged to be deficient, inaccurate, or biased, it could subject us to liability or regulatory scrutiny, and our reputation, business, financial condition, and results of operations may be adversely affected.

Risks Related to Us and Our Subsidiaries Generally

We may not continue to pay dividends at the same rate we are currently paying them, or at all, and any decrease in or suspension of payment of a dividend could cause our stock price to decline.

The payment of future cash dividends is subject to the determination each quarter by our board of directors that the dividend remains in the best interests of the Company and our stockholders, which determination will be based on a number of factors, including, among others, economic conditions, our earnings, financial condition, actual and forecasted cash flows, capital resources, capital requirements and alternative uses of capital, including potential investments to support our business strategy and possible acquisitions or investments in new businesses. Any decrease in the amount of the dividend, or suspension or discontinuance of payment of a dividend, could cause our stock price to decline.

We are subject to litigation and regulatory proceedings.

We operate in highly regulated industries that are subject to a heightened risk of litigation and regulatory proceedings. From time to time we are a party to material litigation and also are subject to legal and regulatory claims, assertions, actions, reviews, audits, inquiries and investigations. Additional lawsuits, legal and regulatory proceedings and inquiries and other matters may arise in the future. The outcome of existing and future legal and regulatory proceedings and inquiries and other matters could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief which could require significant expenditures or have a material adverse effect on our business prospects, results of operations and financial condition. See “Item 1. Business—Regulation,” “Item 3. Legal Proceedings” and Note 13 of Notes to Consolidated Financial Statements.

We rely on our management team and our business could be harmed if we are unable to retain qualified personnel or successfully develop and/or recruit their replacements.

Our success depends, in part, on the skills, working relationships and continued services of our management team and other key personnel, any of whom could terminate his or her relationship with us at any time. Competition for personnel is

60

Part I. Item 1A. Risk Factors

intense and has further increased in light of evolving labor and employment trends, including but not limited to the increase in remote, hybrid or other alternative flexible work arrangements and in many jurisdictions, laws and regulations aimed at limiting or eliminating the enforceability of non-competition and other restrictive covenants with employees. As a result of the flexible working arrangements within many industries, including ours, there is a higher likelihood that highly skilled individuals may seek to change employers in pursuit of greater opportunities or greater benefits. In the current labor and employment environment, it may be more difficult to retain key personnel or to attract new resources who now may have greater optionality among potential employers given the ability to work from home.

The unexpected departure of key personnel could adversely affect the conduct of our business. In such event, we would be required to obtain other personnel to manage and operate our business. In addition, we will be required to replace the knowledge and expertise of our workforce as our workers retire. In either case, there can be no assurance that we will be able to develop or recruit suitable replacements for the departing individuals, that replacements could be hired, if necessary, on terms that are favorable to us, or that we can successfully transition such replacements in a timely manner. Failure to effectively implement our succession planning efforts and to ensure effective transfers of knowledge and smooth transitions involving members of our management team and other key personnel could adversely affect our business and results of operations. Without a properly skilled and experienced workforce, our costs, including costs associated with a loss of productivity and costs to replace employees, may increase, and this could negatively impact our earnings.

Investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business subject us to additional risks and uncertainties.

In support of our growth and diversification strategy, we may make investments to grow our existing businesses, pursue new lines of business or new products and services within existing lines of business. We may do this through strategic transactions, including investments and acquisitions, or pursue other transformative actions and initiatives. These activities expose us to additional risks and uncertainties that include, without limitation:

■the use of capital and potential diversion of other resources, such as the diversion of management’s attention from our core businesses and potential disruption of those businesses;

■the assumption of liabilities in connection with any strategic transaction, including any acquired business;

■our ability to comply with additional regulatory requirements associated with new products, services, lines of business or other business or strategic initiatives;

■our ability to successfully integrate or develop the operations of any new business initiative or acquisition;

■new or existing business initiatives may be disruptive to, or competitive with, our existing customers;

■we may fail to realize the anticipated benefits of a strategic transaction or initiative, including expected synergies, cost savings or sales or growth opportunities, within the anticipated timeframe or at all;

■new business initiatives may expose us to liquidity risk, risks associated with the use of financial leverage, and market risks, including risk resulting from changes in the fair values of assets in which we invest. Further, new business initiatives may increase our exposure to interest rate risk and may involve changes in our investment, financing and hedging strategies;

■we may fail to achieve forecasted results for a strategic transaction or initiative that could result in lower or negative earnings contribution and/or impairment charges associated with intangible assets acquired;

■the risk of reputational harm if the strategic transaction or initiative fails to increase our market value; and

■the risk that any of the above could alter our risk profile or perceived financial strength such that we experience ratings downgrades or other unfavorable changes in how we are perceived by our customers, regulators, counterparties and other stakeholders.

Item 1C. Cybersecurity

Cybersecurity Governance and Risk Management

Information security is a significant operational risk for financial institutions such as Radian and includes the risk of loss resulting from cyberattacks.

To help mitigate this risk, Radian has designed and maintains an Information Security Program that is intended to protect our corporate data as well as data entrusted to us by our customers and partners. The Information Security Program is built on a risk-based approach that identifies and prioritizes cyber threats based on their potential impact on our strategy, operations, and assets. This program extends across all business lines and encompasses written policies on cybersecurity.

The Company has assigned executive ownership of and accountability for the Information Security Program to the Chief Information Security Officer, who leads a dedicated team of trained staff to protect the confidentiality, integrity and availability of information assets. Our Chief Information Security Officer has over 20 years of diverse industry experience, including serving in similar roles overseeing cybersecurity programs, as well as serving in numerous board and advisory capacities. Several members of the Information Security team hold advanced degrees as well as industry-recognized certifications in cybersecurity and related disciplines. The Information Security Program also utilizes third-party managed security services where appropriate.

Our Information Security Program utilizes multiple layers of security controls that are intended to protect information assets and operations. As a guideline to manage our cybersecurity-related risk, we use the National Institute of Standards and Technology Cybersecurity Framework, which outlines information security measures and controls over five functions: Identify, Protect, Detect, Respond and Recover. This does not imply that we meet any particular technical standards, specifications, or requirements. Our risk management process is designed for the purpose of identifying, assessing and mitigating potential threats and uncertainties that may impact the achievement of our business objectives. This process involves engaging relevant stakeholders, conducting regular risk assessments, and staying informed about industry-specific risks and market trends. Identified risks are evaluated based on their potential impact and likelihood of occurrence.

As a Company, we have developed key security services, including data governance, encryption, vulnerability management, systems and network monitoring, access controls, application security, threat detection, incident response, employee awareness training, and assessment of our third-party service providers. We regularly test our incident response readiness and reporting through tabletop exercises, external and internal penetration testing and internal security testing so that identified risks and incidents are escalated and communicated for appropriate remediation activities that are intended to reduce risks to an acceptable level.

Our board of directors has ultimate oversight of cybersecurity risk, which it manages in coordination with our Risk Committee as part of our enterprise risk management program. The Risk Committee regularly reviews the Company’s enterprise risk management program and Information Security Program with management and reports to the board of directors.

To maintain governance and oversight over the Information Security Program, we have established an Information Security Council and Executive Information Security Committee composed of our Chief Information Security Officer and colleagues with experience, education and ongoing training in information security, cybersecurity risk and information governance. We also utilize both internal and external auditors to provide independent assessments of our Information Security Program. Cybersecurity incidents are reviewed at least quarterly by management, the appropriate executive committees and the board of directors or its committees. The Chief Information Security Officer reports directly to our General Counsel and presents at least annually to the Company’s full board of directors about the overall effectiveness of the Information Security Program, as well as quarterly to the Risk Committee of the Company’s board of directors. Radian’s board of directors approves the written Information Security Policy and Information Security Program documents annually. Collectively, these documents describe the structure, scope, organization and requirements of the Information Security Program, as well as the responsibility and authority of the Chief Information Security Officer.

During the reporting period, we were not impacted by any cybersecurity incidents that we believe are reasonably likely to materially affect our business strategy, results of operations, or financial condition.

While the Information Security Program is reasonably designed to mitigate the risk of cybersecurity events, we cannot provide assurance that we will not be subject to a cybersecurity event. In “Item 1A. Risk Factors,” see “We could incur significant liability or reputational harm if the security of our information technology systems, or of our third-party vendors or service providers, is breached, including as result of a cyberattack, or we otherwise fail to protect confidential information, including personally identifiable information that we maintain.”

Item 2. Properties

In addition to leases of other properties and facilities to support our business operations, we currently lease approximately 30,000 square feet of office and storage space for our corporate headquarters, located at 550 East Swedesford Road, Suite 350, in Wayne, Pennsylvania. This property is used by both our reportable segments and our corporate functions.

During 2021, in connection with our shift to a more flexible hybrid work environment following the onset of the COVID-19 pandemic, we made the decision to exit, and actively market for sublease, our former corporate headquarters comprised of 150,000 square feet of leased office and storage space at 1500 Market Street, West Tower, in Philadelphia, Pennsylvania. We have entered into agreements to sublease some of the vacated office space and continue to actively market the remaining space for sublease. In the future, we may choose to enter into additional sublease arrangements with regard to our other leased office locations.

We believe our existing properties are suitable and adequate for their intended use. See Note 13 of Notes to Consolidated Financial Statements for additional information regarding our lease commitments.

Item 3. Legal Proceedings

We are routinely involved in a number of legal actions and proceedings, including reviews, audits, inquiries, information-gathering requests and investigations by various regulatory entities, as well as litigation and other disputes arising in the ordinary course of our business. Legal actions and proceedings could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief that could require significant expenditures or have other effects on our business.

Management believes, based on current knowledge and after consultation with counsel, that the outcome of currently pending or threatened actions will not have a material adverse effect on our consolidated financial condition or results of operations. The outcome of legal actions and proceedings is inherently uncertain, and it is possible that any one or more matters could have an adverse effect on our liquidity, financial condition or results of operations for any particular period. See Note 13 of Notes to Consolidated Financial Statements for additional information regarding legal proceedings and regulatory matters.

Overview

We are a mortgage and real estate company with two reportable business segments—Mortgage Insurance and homegenius.

Our Mortgage Insurance segment aggregates, manages and distributes U.S. mortgage credit risk for the benefit of mortgage lending institutions and mortgage credit investors, principally through private mortgage insurance on residential first-lien mortgage loans, and also offers other credit risk management solutions, including contract underwriting, to our customers. Our homegenius segment offers an array of title, real estate and real estate technology products and services primarily to consumers, mortgage lenders, mortgage and real estate investors, the GSEs, real estate brokers and agents, and corporations for their employees.

See Note 4 of Notes to Consolidated Financial Statements for additional information about our businesses. See “Key Factors Affecting Our Results” below for information about the key drivers that affect our performance.

Current Operating Environment

As a mortgage and real estate company, our business results are subject to macroeconomic conditions and specific events that impact the housing, housing finance and residential real estate markets and the credit performance of our mortgage insurance portfolio, as well as seasonal fluctuations impacting mortgage and real estate markets. Among others, these factors may include home prices and housing supply, inflationary pressures, interest rate changes, unemployment levels, the volume of mortgage originations and the availability of credit, national and regional economic conditions, legislative and regulatory developments and other events, including macroeconomic stresses and uncertainties resulting from global conflicts and other geopolitical events. See “Item 1A. Risk Factors” for a discussion of material risks that could impact our business results.

As further discussed below, the following economic and market conditions represent the primary factors affecting the current operating environment for our businesses.

Inflationary Pressures and Elevated Interest Rates. Annual inflation in the U.S. reached a 40-year high in 2022. To reduce inflation, the U.S. Federal Reserve has increased interest rates significantly since 2021, resulting in a sharp and

65

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

significant increase in mortgage interest rates. Among other negative impacts on our business, these macroeconomic conditions have reduced the overall volume of mortgage transactions taking place, which in turn, has reduced the amount of NIW we are writing. Conversely, the higher interest rate environment also has benefited our financial performance through higher Persistency Rates, which has resulted in continued growth in our IIF despite lower NIW, as well as through the recognition of higher net investment income. More recently, mortgage rates have decreased from their peak in the third quarter of 2023, and with inflation beginning to moderate, the U.S. Federal Reserve has indicated that it could begin to reduce interest rates in 2024. Although in recent years the inflationary pressures and higher interest rate environment discussed above have negatively impacted the U.S. housing market, including broadly reducing refinance activity, longer-term, we continue to believe that the housing market fundamentals and outlook remain favorable, including demographics supporting growth in the population of first-time homebuyers and a constrained supply of homes available for sale with available homes near historical lows. See “Mortgage Insurance Portfolio” for additional details on our NIW and IIF. The same inflationary pressures and interest rate environment discussed above have also negatively impacted our homegenius businesses, due primarily to the rapid decline in industry-wide purchase and refinance volumes, which has resulted in a continued decline in homegenius revenues since the beginning of 2022 and ongoing losses for that business segment.

Home Price Appreciation and Limited Housing Supply. Our mortgage insurance business generally benefits from increases in housing demand, home prices and the volume of home purchases, all of which are influenced by the current market imbalance between a constrained housing supply and strong market demand. While the housing shortage combined with strong market demand has created affordability challenges for many first-time homebuyers, the same dynamic benefits our existing insurance written by mitigating against the risks of loss to us associated with a decrease in home values. As a result, paid claim volumes and severity in our mortgage insurance business have been positively affected by the current environment. Further, as discussed below, we believe the embedded equity borrowers have in their homes as a result of strong home price appreciation in recent years is a factor that is positively impacting our loan default and Cure trends, and importantly, the strong demographics supporting continued demand from first-time homebuyers are likely to continue to support home prices and drive further growth in purchase originations that is expected to grow our IIF. See “Mortgage Insurance Portfolio—New Insurance Written” for expectations on mortgage origination volumes.

Strong Credit Environment, Positively Impacting Default and Cure Trends. In 2020, the onset of the COVID-19 pandemic resulted in a significant increase in unemployment and had a negative impact on the economy. As a result, we experienced a material increase in new defaults beginning in the second quarter of 2020, substantially all of which related to loans subject to mortgage forbearance programs implemented in response to the COVID-19 pandemic. This increase in new defaults resulted in an increase in our reserve for losses and had a negative effect on our results of operations for that year. Since 2020 and continuing through December 31, 2023, subsequent trends in Cures have been more favorable than original expectations, resulting in favorable loss reserve development in 2022 and 2023 on prior period defaults due to stable and low levels of unemployment and the strong home price appreciation in recent years. As of December 31, 2023, based on a home price index-based approach using industry averages, we estimate that 86% of our total IIF had at least 10% embedded equity and 82% of defaulted loans had at least 20% embedded equity. The significant embedded equity that borrowers in our insured portfolio have in their homes has helped to mitigate our risk of loss by decreasing both the frequency and severity of our paid claims. These positive trends have also contributed to a higher rate of claims that result in no ultimate loss and that are withdrawn by servicers as a result. While the recent credit and housing trends have been favorable, the number of defaults that ultimately result in claims in the future is difficult to predict and will depend on a variety of factors, including the overall economic environment and the natural seasoning of our growing IIF portfolio. See Note 11 of Notes to Consolidated Financial Statements for additional information on our reserve for losses.

Improvements in Mortgage Finance System and Mortgage Insurance Fundamentals. Despite risks and uncertainties, we believe that mortgage industry fundamentals remain strong and have benefited from improvements to the mortgage and real estate ecosystem since the great financial crisis in 2008, including more stringent underwriting and product standards, higher-quality borrowers with strong credit profiles and strengthened servicing standards and government support to help borrowers stay in their homes. In addition, enhancements in the mortgage insurance industry since the great financial crisis in 2008, including the implementation of strong capital and operating standards under the PMIERs, the implementation of greater risk-based granularity into our pricing methodologies and the increased use of risk distribution strategies to lower the risk profile and financial volatility of our mortgage insurance portfolio, have increased returns on our NIW, provided capital relief under the PMIERs and have helped position our mortgage insurance business to better withstand the negative effects from macroeconomic stresses discussed above, including those resulting from the higher rates of inflation and higher interest rates, as well as the other risks described in “Item 1A. Risk Factors.”

Our current business structure is highly dependent on the GSEs, as the GSEs are the primary beneficiaries of most of our mortgage insurance policies, and mortgage insurers such as Radian Guaranty must meet the GSEs’ eligibility requirements to be eligible to insure loans purchased by the GSEs. The FHFA and GSEs have significant discretion under the PMIERs and may amend the PMIERs at any time. Changes in the PMIERs or business practices of the GSEs can significantly impact our business. In addition, our businesses operate within the housing finance system and a change in government administrations can significantly alter the strategic direction of housing finance in the U.S. and impact our businesses and financial performance. Our businesses are subject to and may be impacted by many federal and state lending, insurance and consumer laws and regulations. See “Item 1. Business—Regulation.”

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Key Factors Affecting Our Results

The following sections discuss certain key drivers affecting our Mortgage Insurance and homegenius businesses, as well as other key factors affecting our results.

Mortgage Insurance

NIW and Related Drivers

NIW increases our IIF and our premiums written and earned. NIW is affected by the overall size of the mortgage origination market, the penetration percentage of private mortgage insurance into the overall mortgage origination market and our market share of the private mortgage insurance market.

The overall mortgage origination market is influenced by macroeconomic factors such as household formation, household composition, home affordability, interest rates, housing markets in general (which are subject to seasonality), credit availability and the impact of various legislative and regulatory actions that may influence the housing and mortgage finance industries.

The penetration percentage of private mortgage insurance is mainly influenced by: (i) the competitiveness of private mortgage insurance for GSE conforming loans compared to FHA and VA insured loans and (ii) the relative percentage of mortgage originations that are for purchased homes versus refinances. We believe, for example, that given current pricing levels, which are subject to change, the generally better execution available through the GSEs for borrowers with higher FICO scores and lender preferences are factors that currently provide a competitive advantage for private mortgage insurers. See “Mortgage Insurance Portfolio—New Insurance Written.”

Private mortgage insurance penetration in the insurable market has generally been higher on new mortgages for purchased homes than on the refinance of existing mortgages, because average LTVs are typically higher on home purchases, and therefore, these lower down payment loans are more likely to require mortgage insurance. Radian Guaranty’s share of the private mortgage insurance market is influenced by competition in that market. See “Item 1. Business—Competition.”

For a historical perspective on key market drivers, see the charts entitled “Mortgage origination market” and “Private mortgage insurance penetration of mortgage origination market” in “Mortgage Insurance Portfolio—New Insurance Written.”

IIF and Related Drivers

Our IIF is one of the primary drivers of our future premiums that we expect to earn over time. Although not reflected in the current period financial statements, nor in our reported book value, we expect our IIF to generate substantial earnings in future periods due to the high credit quality of our current mortgage insurance portfolio and our expectations for future Persistency Rates.

The ultimate profitability of our mortgage insurance business is affected by the impact of mortgage prepayment speeds on the mix of business we write. The measure for assessing the impact of policy cancellations on our IIF is our Persistency Rate, defined as the percentage of IIF that remains in force over a period of time. Assuming all other factors remain constant, over the life of the policies, prepayment speeds have an inverse impact on IIF and the expected revenue from our Monthly Premium Policies. Slower loan prepayment speeds, demonstrated by a higher Persistency Rate, result in more IIF remaining in place, providing increased revenue from Monthly Premium Policies over time as premium payments continue. Earlier than anticipated loan prepayments, demonstrated by a lower Persistency Rate, reduce IIF and the revenue from our Monthly Premium Policies. Among other factors, prepayment speeds may be affected by changes in interest rates and other macroeconomic factors. A rising interest rate environment generally will reduce refinancing activity and result in lower prepayments, whereas a declining interest rate environment generally will increase the level of refinancing activity and therefore increase prepayments.

In contrast to Monthly Premium Policies, when Single Premium Policies are canceled by the insured because the loan has been paid off or otherwise, we accelerate the recognition of any remaining unearned premiums, net of any refunds that may be owed to the borrower. Although these cancellations reduce IIF, assuming all other factors remain constant, the profitability of our Single Premium business increases when Persistency Rates are lower. As a result, we believe that writing a mix of Single Premium Policies and Monthly Premium Policies has the potential to moderate the overall impact on our results if actual prepayment speeds are significantly different from expectations. However, the impact of this moderating effect may be affected by the amount of reinsurance we obtain on portions of our portfolio, with the Single Premium QSR Program currently reducing the proportion of retained Single Premium Policies in our portfolio.

At December 31, 2023, approximately 89% of our total Primary Mortgage RIF are Monthly and Other Recurring Premium Policies. Based on the current composition of our mortgage insurance portfolio, with Monthly Premium Policies comprising a larger proportion of our total portfolio than Single Premium Policies, an increase in IIF generally has a corresponding positive impact on premiums earned, while a decrease in IIF generally has a corresponding negative impact on premiums earned.

67

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Cancellations of our insurance policies as a result of prepayments and other reductions of IIF, such as Rescissions of coverage and claims paid, generally have a negative effect on premiums earned over time. See “Mortgage Insurance Portfolio—Insurance and Risk in Force” for more information about the levels and characteristics of our IIF.

Premiums

The premium rates we charge for our insurance are based on a number of borrower, loan and property characteristics. The mortgage insurance industry is highly competitive and private mortgage insurers compete with each other and with the FHA and VA with respect to price and other factors.

Our pricing is risk-based and is intended to generally align with the capital requirements under the PMIERs, while also considering pricing trends within the private mortgage insurance industry among other factors. As a result, our pricing is expected to generate relatively consistent returns across the credit spectrum. In developing our pricing strategies, we monitor various competitive and economic factors while seeking to maximize the long-term economic value of our portfolio by balancing credit risk, lender and geographic concentration risk, profitability and volume considerations, and aim to achieve an overall risk-adjusted rate of return on capital given our modeled performance expectations. Our actual portfolio returns will depend on a number of factors, including economic conditions, the mix of NIW that we are able to write, our pricing, the amount of reinsurance we use and the level of capital we hold, including amounts that may be in excess of minimum PMIERs financial and statutory capital requirements.

Our pricing actions gradually affect our results over time, as existing IIF cancels and is replaced with NIW at current pricing. See “Mortgage Insurance Portfolio—New Insurance Written” and “Liquidity and Capital Resources—Mortgage Insurance” for additional information.

As described above, premiums on our mortgage insurance products are generally paid either on an installment basis, pursuant to Monthly Premium Policies, or in a single payment at the time of loan origination, pursuant to Single Premium Policies. See “Item 1. Business—Mortgage Insurance—Pricing—Primary Mortgage Insurance Premiums.” As discussed above, the ultimate profitability of Single Premium Policies may be higher or lower than expected due to the impact of prepayment speeds. See “IIF and Related Drivers” above.

Monthly Premium Policies typically provide a level monthly premium for the first 10 years of the policy, followed by a lower level monthly premium thereafter. Generally, a borrower is able to cancel the policy when the LTV reaches 80% of the original value, and the servicer is required to review the policy for automatic cancellation on the date the LTV is scheduled to reach 78% of the original value. As a result, the volume of loans that remain insured after 10 years and would be subject to the premium reset is generally not material in relation to the total loans originated. However, to the extent the volume of loans resetting from year to year varies significantly, the trend in earned premiums may also vary.

Losses

Incurred losses represent the estimated future claim payments on newly defaulted insured loans as well as any change in our claim estimates for existing defaults, including changes in our estimates with respect to the frequency, magnitude and timing of anticipated losses on defaulted loans. Other factors influencing incurred losses include:

■The mix of credit characteristics in our total direct RIF (e.g., loans with higher risk characteristics, or loans with layered risk that combine multiple higher-risk attributes within the same loan, generally result in more delinquencies and claims). See “Mortgage Insurance Portfolio—Insurance and Risk in Force;”

■The average loan size (relatively higher priced properties with larger average loan amounts may result in higher incurred losses);

■The percentage of coverage on insured loans (higher percentages of insurance coverage generally correlate with higher incurred losses) and the presence of structural mitigants such as deductibles or stop losses;

■Changes in housing values (declines in housing values generally make it more difficult for borrowers to sell a home to avoid default or for the property to be sold to mitigate a claim, and also may negatively affect a borrower’s willingness to continue to make mortgage payments when the home value is less than the mortgage balance; conversely, increases in housing values tend to reduce the level of defaults as well as make it more likely that foreclosures will result in the loan being satisfied);

■The distribution of claims over the life cycle of a portfolio (historically, claims are relatively low during the first two years after a loan is originated and then increase over a period of several years before declining; however, several factors can impact and change this cycle, including the economic environment, the quality of the underwriting of the loan, characteristics of the mortgage loan, the credit profile of the borrower, housing prices and unemployment rates); and

■Our ability to mitigate potential losses through Rescissions, Claim Denials, cancellations and Claim Curtailments on claims submitted to us. In “Item 1A. Risk Factors,” see “Our Loss Mitigation Activity could negatively impact our customer relationships.”

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Risk Distribution

We use third-party reinsurance in our mortgage insurance business to manage capital and risk in an effort to optimize the amounts and types of capital and risk distribution deployed against insured risk. We have distributed risk through traditional quota share and excess-of-loss reinsurance arrangements, as well as to investors through the capital markets using mortgage insurance-linked notes transactions. See “IIF and Related Drivers” above.

When we enter into a quota share reinsurance agreement, the reinsurer receives a premium and, in exchange, agrees to insure an agreed upon portion of incurred losses. These arrangements reduce our earned premiums but also reduce our net RIF, which provides capital relief, including under the PMIERs financial requirements. In addition, our incurred losses are reduced by any incurred losses ceded in accordance with the reinsurance agreement, which reduces the volatility of our provision for losses in certain stressed economic environments, and we often receive ceding commissions from the reinsurer as part of the transaction, which, in turn, reduce our reported operating expenses and policy acquisition costs.

Our XOL Program accesses reinsurance coverage through traditional excess-of-loss reinsurance arrangements, as well as through the capital markets through the Eagle Re Issuers’ mortgage insurance-linked notes transactions. Our XOL Program reduces our earned premiums, but also reduces our net RIF and PMIERs financial requirements, and potentially our incurred losses, which are allocated in accordance with the structure of the transaction. The Eagle Re Issuers are special purpose VIEs that are not consolidated in our consolidated financial statements because we do not have the unilateral power to direct those activities that are significant to their economic performance.

See Note 8 of Notes to Consolidated Financial Statements for more information about our reinsurance arrangements, including the total assets and liabilities of the Eagle Re Issuers.

Investment Income

Investment income is determined primarily by the investment balances held and the average yield on our overall investment portfolio.

Other Operating Expenses

Our other operating expenses include salaries and other base employee costs, variable and share-based incentive compensation and other general operating expenses, such as fees for professional and consulting services, software, rent and depreciation, among other costs. Employee related expenses are driven by our headcount, which can fluctuate due to the amount of our NIW and IIF, as well as our plans for other business initiatives. Our other operating expenses may also fluctuate due to the impact of performance on our incentive compensation programs, as a result of our pay-for-performance approach to compensation that is based on the level of achievement of both short-term and long-term goals.

These operating expenses are reported net of ceding commissions associated with our QSR Program. As a result, changes to our QSR Program and the amount of our ceded premiums earned also can impact our other operating expenses.

homegenius

Premiums

We earn net premiums on title insurance through Radian Title Insurance. Demand for title insurance may be impacted by general marketplace competition in the real estate title industry, coupled with housing market related conditions such as new home sales, the sizes of the real estate purchase and refinance markets and interest rate fluctuations.

Services Revenue

Our homegenius segment is dependent upon overall activity in the mortgage finance and real estate markets, as well as market receptivity to the products we offer. Due, in part, to the transactional nature of the business, revenues for our homegenius segment are subject to fluctuations from period to period, including seasonal fluctuations that reflect the activities in these markets. Sales volume is also affected by the number of competing companies and alternative products offered in the market. We believe the diversity of services we offer has the potential to produce fee income from the homegenius segment throughout various mortgage finance environments and economic cycles, although market conditions can significantly impact the mix and amount of fee income we generate in any particular period. See “Item 1. Business—homegenius—Overview” for more information on our homegenius services.

The homegenius segment is dependent on a limited number of large customers that represent a significant portion of its revenues. Generally, our contracts do not contain volume commitments and may be terminated by clients at any time. While access to Radian Guaranty’s mortgage insurance customer base provides additional opportunities to expand the homegenius segment’s existing customers, an unexpected loss of a major customer could significantly impact the level of homegenius revenue.

69

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our homegenius revenue is primarily generated under fixed-price contracts. Under fixed-price contracts, we agree to perform the specified services and deliverables for a predetermined per-unit price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss. See Note 2 of Notes to Consolidated Financial Statements for more information on revenue recognition policies for our homegenius segment.

Cost of Services

Our cost of services is primarily affected by our level of services revenue and the number of employees providing products and services for our homegenius businesses. Our cost of services primarily consists of employee compensation and related payroll benefits, and to a lesser extent, other costs of providing services such as travel and related expenses incurred in providing client services, costs paid to outside vendors, data acquisition costs and other costs to maintain software platforms that directly support our businesses. The level of these costs may fluctuate as market rates of compensation change, or if there is decreased availability or a loss of qualified employees.

Operating Expenses

Our operating expenses primarily consist of salaries and benefits not classified as cost of services because they are related to employees, such as sales and corporate employees, who are not directly involved in providing client services. Operating expenses also include other selling, general and administrative expenses, depreciation and allocations of corporate general and administrative expenses.

See “Item 1. Business—homegenius—Overview” and Note 1 of Notes to Consolidated Financial Statements for additional information regarding the homegenius segment.

Net Gains (Losses) on Investments and Other Financial Instruments

In addition, net gains (losses) on investments and other financial instruments also may impact our consolidated results in the ordinary course. The recognition of realized investment gains or losses can vary significantly across periods, as the activity is highly discretionary based on the timing of individual securities sales due to such factors as market opportunities, our tax and capital profile and overall market cycles. Unrealized gains and losses arise primarily from changes in the market value of our investments that are classified as trading or equity securities, as well as changes in the value of mortgage loans held by Radian Mortgage Capital. These valuation adjustments may not necessarily result in realized economic gains or losses.

Mortgage Insurance Portfolio

New Insurance Written

A key component of our current business strategy is to write NIW that we believe will generate future earnings and economic value while effectively maintaining the portfolio’s health, balance and profitability. Consistent with this objective, we wrote $52.7 billion of primary new mortgage insurance in 2023, compared to $68.0 billion of NIW in 2022. Our NIW decreased by 22% in 2023 as compared to 2022, due to a broad decline in U.S. housing market activity primarily resulting from higher mortgage interest rates, partially offset by an increase in our market share in 2023.

Among other factors, private mortgage insurance industry volumes are impacted by total mortgage origination volumes and the mix between mortgage originations that are for home purchases versus refinancings of existing mortgages. Historically, the penetration rate for private mortgage insurance generally has been three to five times higher for purchase transactions than for refinancings. However, with significant home price appreciation in recent years, penetration on purchase transactions has increased while penetration on refinancings has decreased, and the penetration rate for private mortgage insurance has shifted to 10 to 14 times higher for purchase transactions than for refinancings.

The following charts provide a historical perspective on certain key market drivers, including:

■the mortgage origination volume from home purchases and refinancings; and

■private mortgage insurance penetration as a percentage of the mortgage origination market.

(2)Excluding originations under HARP.

According to industry estimates, total mortgage origination volume was significantly lower in 2023 as compared to 2022 due to a significant decline in mortgage refinance activity and a smaller decline in home purchases. Although it is difficult to project future volumes, recent industry projections for 2024 estimate total mortgage originations of approximately $2.0 trillion, which would represent an increase in the total annual mortgage origination market of approximately 27% as compared to 2023.

Factoring in our projections of private mortgage insurance penetration in the overall insurable mortgage market, we estimate that the private mortgage insurance market will be between $300 billion and $350 billion in 2024 as compared to a reported market of approximately $285 billion in 2023. There is an industry-wide consensus that we should expect a healthy purchase market in 2024 driven by ongoing homebuyer demand and an expected decline in interest rates, which is a positive for mortgage insurers given the higher likelihood that purchase loans will utilize private mortgage insurance as compared to refinance loans. This outlook also anticipates an increase in refinance originations in 2024 resulting from reduced interest rates.

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Our IIF is the primary driver of the future premiums that we expect to earn over time. IIF increased to $270.0 billion at December 31, 2023, from $261.0 billion at December 31, 2022, reflecting the impact of our NIW offset by policy cancellations and amortization. Our IIF at December 31, 2023, increased 3% as compared to the same period last year, reflecting a 6% increase in Monthly Premium Policies in force partially offset by a 10% decline in Single Premium Policies in force.

Historically, there is a close correlation between interest rates and Persistency Rates. Higher interest rate environments generally decrease refinancings, which decrease the cancellation rate of our insurance and positively affect our Persistency Rates. As shown in the table below, our 12-month Persistency Rate at December 31, 2023, increased as compared to the same period in 2022. The increase in our Persistency Rate in 2023 was primarily attributable to decreased refinance activity due to increases in mortgage interest rates, as compared to the prior year. As of December 31, 2023, 81% of our IIF had a mortgage note interest rate of 6.0% or less and 69% of our IIF had a mortgage note rate of 5.0% or less. Given the increase in market mortgage interest rates, which, based on reported industry averages, now exceed these levels, we would expect a continued positive impact on our Persistency Rates. If refinance volume increases, we would expect the Persistency Rate for our portfolio to decrease, reducing the size of our IIF portfolio. See “Item 1A. Risk Factors” for more information.

As discussed above, our earnings in future periods are subject to elevated risks and uncertainties related to macroeconomic conditions and specific events that impact the housing finance and real estate markets, including housing prices, inflationary pressures, unemployment levels, interest rate changes and the availability of credit. For additional information, in “Item 1A. Risk Factors,” see “The credit performance of our mortgage insurance portfolio is impacted by macroeconomic conditions and specific events that affect the ability of borrowers to pay their mortgages.”

While these risks and uncertainties are elevated in the near-term, we continue to believe that the long-term housing market fundamentals and outlook remain positive, including demographics supporting growth in the population of first-time homebuyers and a relatively constrained supply of homes available for sale. In addition, historical loan performance data indicates that credit scores and underwriting quality are key drivers of credit performance, and loan originations after 2008 have consisted primarily of high credit quality loans with significantly better credit performance than loans originated during 2008 and prior periods.

The following table illustrates the trends of our cumulative incurred loss ratios by year of origination and development year.

Risk Distribution

We use third-party reinsurance in our mortgage insurance business as part of our risk distribution strategy, including to manage our capital position and risk profile. When we enter into a reinsurance agreement, the reinsurer receives a premium and, in exchange, insures an agreed upon portion of incurred losses. While these arrangements reduce our earned premiums, they also reduce our required capital and are expected to increase our return on required capital for the related policies.

The impact of these programs on our financial results will vary depending on the level of ceded RIF, as well as the levels of prepayments and incurred losses on the reinsured portfolios, among other factors. See “Key Factors Affecting Our Results—Mortgage Insurance—Risk Distribution” and Note 8 of Notes to Consolidated Financial Statements for more information about our reinsurance transactions.

The table below provides information about the amounts by which Radian Guaranty’s reinsurance programs reduced its Minimum Required Assets as of the dates indicated.

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Revenues

Net Premiums Earned. The decrease in net premiums earned for 2023 compared to 2022 is primarily driven by decreases in net premiums earned in both our mortgage insurance and title insurance businesses in 2023. For more information, see “Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Revenues—Net Premiums Earned” under both “Results of Operations—Mortgage Insurance” and “Results of Operations—homegenius.”

Services Revenue. Services revenue for 2023 decreased compared to 2022, primarily driven by the general market decline in mortgage origination volume as well as other market and macroeconomic conditions, as further described above in “Overview—Current Operating Environment.” For more information, see “Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Revenues—Services Revenue” under both ““Results of Operations—Mortgage Insurance” and “Results of Operations—homegenius.”

Net Investment Income. The increase in net investment income for 2023 compared to 2022 is primarily attributable to higher yields in 2023 driven by increased market interest rates on new purchases. See “Overview—Current Operating Environment” and “Results of Operations—Mortgage Insurance—Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Revenues—Net Investment Income” for more information.

Net Gains (Losses) on Investments and Other Financial Instruments. The favorable change in net gains (losses) on investments and other financial instruments for 2023, as compared to 2022, is primarily due to: (i) the general positive movement in equity markets in 2023, compared to 2022, and (ii) moderately lower market interest rates in 2023, compared to the sharp rise in market interest rates in 2022, as further discussed above in “Overview—Current Operating Environment.” See Note 6 of Notes to Consolidated Financial Statements for additional information about net gains (losses) on investments and other financial instruments by investment category.

Expenses

Provision for Losses. The reduced benefit of the provision for losses for 2023 compared to 2022 is primarily driven by a reduction in favorable development on prior year defaults, which impacted our mortgage insurance reserves. See “Results of Operations—Mortgage Insurance—Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Expenses—Provision for Losses” for more information.

Cost of Services. Cost of services for 2023 decreased as compared to 2022, primarily driven by the decrease in services revenue as discussed above. For more information, see “Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Expenses—Cost of Services” under both “Results of Operations—Mortgage Insurance” and “Results of Operations—homegenius.”

Other Operating Expenses. The decrease in other operating expenses for 2023 compared to 2022 is primarily due to: (i) a decrease in salaries and other base employee expenses and (ii) a decrease in other general operating expenses. These decreases were partially offset by a net increase in variable and share-based compensation expense. Our other operating expenses include impairments of other long-lived assets and other non-operating expenses of $13 million in 2023, primarily related to our lease agreements and impairment of internal-use software, and $15 million in 2022, primarily related to our lease agreements. For more information, see “Year Ended December 31, 2023, Compared to Year Ended December 31, 2022—Expenses—Other Operating Expenses” under both ““Results of Operations—Mortgage Insurance” and “Results of Operations—homegenius.”

Income Tax Provision

Our 2023 effective tax rate was 21.4%, generally consistent with the federal statutory rate of 21%. State income taxes and certain permanent book-to-tax adjustments were the primary drivers of minor differences in the effective tax rate compared to the federal statutory rate. See Note 10 of Notes to Consolidated Financial Statements for a reconciliation of our provision for income taxes.

Use of Non-GAAP Financial Measures

In addition to the traditional GAAP financial measures, we have presented “adjusted pretax operating income (loss),” “adjusted diluted net operating income (loss) per share” and “adjusted net operating return on equity,” which are non-GAAP financial measures for the consolidated company, among our key performance indicators to evaluate our fundamental financial performance. These non-GAAP financial measures align with the way our business performance is evaluated by both management and by our board of directors. These measures have been established in order to increase transparency for the purposes of evaluating our operating trends and enabling more meaningful comparisons with our peers. Although on a consolidated basis, adjusted pretax operating income (loss), adjusted diluted net operating income (loss) per share and adjusted net operating return on equity are non-GAAP financial measures, for the reasons discussed above we believe these measures aid in understanding the underlying performance of our operations.

Total adjusted pretax operating income (loss), adjusted diluted net operating income (loss) per share and adjusted net operating return on equity are not measures of overall profitability, and therefore should not be considered in isolation or viewed as substitutes for GAAP pretax income (loss), diluted net income (loss) per share or return on equity. Our definitions of adjusted pretax operating income (loss), adjusted diluted net operating income (loss) per share and adjusted net operating return on equity, as discussed and reconciled below to the most comparable respective GAAP measures, may not be comparable to similarly named measures reported by other companies.

Our senior management, including our Chief Executive Officer (Radian’s chief operating decision maker), uses adjusted pretax operating income (loss) as our primary measure to evaluate the fundamental financial performance of our business segments and to allocate resources to the segments.

Adjusted pretax operating income (loss) is defined as GAAP consolidated pretax income (loss) excluding the effects of: (i) net gains (losses) on investments and other financial instruments, except for certain investments and other financial instruments attributable to our reportable segments and All Other activities; (ii) amortization and impairment of goodwill and other acquired intangible assets; and (iii) impairment of other long-lived assets and other non-operating items, if any, such as gains (losses) from the sale of lines of business, acquisition-related income and expenses and gains (losses) on extinguishment of debt.

Although adjusted pretax operating income (loss) excludes certain items that have occurred in the past and are expected to occur in the future, the excluded items represent those that are: (i) not viewed as part of the operating performance of our primary activities or (ii) not expected to result in an economic impact equal to the amount reflected in pretax income (loss). These adjustments, along with the reasons for their treatment, are described in Note 4 of Notes to Consolidated Financial Statements.

The following table provides a reconciliation of consolidated pretax income to our non-GAAP financial measure for the consolidated Company of adjusted pretax operating income.

Year Ended December 31, 2023, Compared to Year Ended December 31, 2022

Revenues

Net Premiums Earned. Net premiums earned decreased for 2023 compared to 2022, primarily due to: (i) a decrease in the profit commission retained by the Company under our reinsurance programs, due to less favorable reserve development in 2023; (ii) an increase in ceded premiums earned under the 2022 QSR Agreement, which began ceding a portion of NIW in the third quarter of 2022, as well as the 2023 QSR Agreement, which began ceding a portion of NIW in the third quarter of 2023; and (iii) a decrease in the benefit, net of reinsurance, from Single Premium Policy cancellations due to lower refinance activity. These impacts were partially offset by an increase in direct premiums earned excluding revenue from cancellations, which benefited 2023 as compared to 2022 due primarily to higher IIF.

Our in force portfolio premium yield was relatively stable for 2023, as compared to 2022. Based on current NIW pricing and the impact of higher Persistency Rates we have been experiencing, we currently expect our in force portfolio premium yield in 2024 to remain stable; however, due to the potential impacts of Single Premium Policy cancellations and reinsurance, among other things, the net premium yield may continue to fluctuate from period to period.

The level of mortgage prepayments affects the revenue ultimately produced by our mortgage insurance business and is influenced by the mix of business we write. See “Key Factors Affecting Our Results—Mortgage Insurance—IIF and Related Drivers” for more information.

Services Revenue. Services revenue for 2023 decreased as compared to 2022, primarily driven by the termination of a large mortgage fulfillment services contract with a customer in the second quarter of 2022, as well as a decrease in demand for our contract underwriting services as a result of the general market decline in mortgage origination volume.

Net Investment Income. Increasing yields from higher interest rates were the primary driver of the increases in net investment income for 2023 compared to 2022.

(2)Related to defaulted loans with a default notice dated in a year earlier than the year indicated, which have been continuously in default since that time.

(3)Provision for losses as a percentage of net premiums earned. See “Revenues—Net Premiums Earned” above for additional information on the changes in net premiums earned.

(4)Calculated by dividing provision for losses for new defaults, net of reinsurance, by the number of new primary defaults for each period.

Current year new primary defaults increased by 17% for 2023, as compared to 2022, consistent with our expectations regarding the natural seasoning of the portfolio given the increase in our IIF in recent years. Our gross Default to Claim Rate assumption for new primary defaults was 8.0% at both December 31, 2023 and 2022. We continue to closely monitor the trends in Cures and claims paid for our default inventory, while also weighing the risks and uncertainties associated with the current economic environment.

Our provision for losses during 2023 and 2022 was positively impacted by favorable reserve development on prior year defaults, primarily as a result of more favorable trends in Cures than originally estimated. These Cures have been due primarily to favorable outcomes resulting from mortgage forbearance programs implemented in response to the COVID-19 pandemic as well as positive trends in home price appreciation, which has also contributed to a higher rate of claims that result in no ultimate loss and that are withdrawn by servicers as a result. These favorable observed trends resulted in reductions in our Default to Claim Rate and other reserve adjustments for prior year default notices. See Notes 1 and 11 of Notes to Consolidated Financial Statements and “Item 1A. Risk Factors” for additional information.

Our primary default rate at both December 31, 2023 and 2022, was 2.2%. The following table shows a rollforward of the number of our primary loans in default.

We develop our Default to Claim Rate estimates on defaulted loans based on models that use a variety of loan characteristics to determine the likelihood that a default will reach claim status. See Note 11 of Notes to Consolidated Financial Statements for additional details about our Default to Claim Rate assumptions.

Our aggregate weighted-average net Default to Claim Rate assumption for our primary defaulted loans used in estimating our reserve for losses, which is net of estimated Claim Denials and Rescissions, was 25% and 30%, at December 31, 2023 and 2022, respectively. This decrease was primarily due to a shift in the mix of defaults as of December 31, 2023, given the larger proportion of loans with fewer missed payments, as well as reduced claim rate assumptions for prior period defaults due to more favorable trends in Cures than originally estimated. See Note 11 of Notes to Consolidated Financial Statements for information regarding our reserve for losses and a reconciliation of our Mortgage Insurance segment’s beginning and ending reserves for losses and LAE.

Although expected claims are included in our reserve for losses, the timing of claims paid is subject to fluctuation from quarter to quarter, based on the rate that defaults cure and other factors, including the impact of foreclosure moratoriums (as further described in “Item 1. Business—Mortgage Insurance—Defaults and Claims”), which make the timing of paid claims difficult to predict.

Cost of Services. Cost of services for 2023 decreased compared to 2022, primarily due to the decrease in services revenue, as discussed above. Our cost of services is primarily affected by our level of services revenue.

Other Operating Expenses. The decrease in other operating expenses for 2023, as compared to 2022, is primarily related to reductions in headcount and other expense savings actions implemented for the segment during the past year. These items were partially offset by an increase in performance-based variable and share-based compensation expense in 2023, primarily as a part of allocated corporate operating expenses.

Results of Operations—homegenius

The following table summarizes our homegenius segment’s results of operations for the periods indicated. As discussed in “Overview—Current Operating Environment,” the macroeconomic stresses beginning in the second quarter of 2022 have continued to impact our homegenius businesses, including in particular a decrease in our title revenues due to the rapid decline in industrywide refinance volumes. We expect this trend to continue to impact the results of our homegenius segment in at least the near-term based on current market conditions and our expectation that overall refinance volumes will remain low.

Year Ended December 31, 2023, Compared to Year Ended December 31, 2022

Revenues

Net Premiums Earned. Net premiums earned for 2023 decreased compared to 2022, primarily due to a decrease in new title policies written in our title insurance business given the decline in industrywide refinance volumes.

Services Revenue. Services revenue for 2023 decreased compared to 2022, primarily due to a decrease in real estate and title services revenues resulting from macroeconomic stresses, as described above. See Note 4 of Notes to Consolidated Financial Statements for the disaggregation of services revenue by revenue type.

Expenses

Cost of Services. Cost of services for 2023 decreased compared to 2022, primarily due to the decrease in services revenue. Our cost of services is primarily affected by our level of services revenue and the number of employees providing those services. The number of employees was reduced in 2023 as compared to 2022, as a result of steps taken primarily in 2022 to better align our workforce with the current and expected needs of our business.

Other Operating Expenses. The following tables show additional information about homegenius’s other operating expenses for the periods indicated. The decrease in other operating expenses for 2023 as compared to 2022 reflects: (i) a decrease in salaries and other base employee expenses, driven primarily by steps taken to align our workforce to the current and expected needs of this business and (ii) a decrease in other general operating expenses in 2023, as a result of additional expense saving actions implemented in 2023. Included in the results for 2023 are severance expenses of $2 million related to additional reductions in headcount in response to the ongoing challenging macroeconomic environment for the homegenius segment’s products and services, as compared to $6 million of severance expense in 2022.

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

All Other also includes the financial results of Radian Mortgage Capital. In light of current market conditions, we have been measured in our approach with our mortgage conduit. Radian Mortgage Capital purchased $221 million and $4 million of mortgage loans during 2023 and 2022, respectively, and, to date, has executed the distribution of loans through whole loan sales. As of December 31, 2023, Radian Mortgage Capital had $33 million of mortgage loans held for sale. See Note 7 of Notes to Consolidated Financial Statements for additional information on our mortgage loans held for sale.

Liquidity and Capital Resources

Consolidated Cash Flows

The following table summarizes our consolidated cash flows from operating, investing and financing activities.

Summary cash flows - Consolidated
	Years Ended December 31,
(In thousands)	2023		2022		2021
Net cash provided by (used in):
Operating activities	$	529,434	$	388,298	$	557,112
Investing activities	(300,842)		(5,175)		(1,862)
Financing activities	(265,087)		(479,183)		(496,776)
Increase (decrease) in cash and restricted cash	$	(36,495)	$	(96,060)	$	58,474

Operating Activities. Our most significant source of operating cash flows is from premiums received from our mortgage insurance policies, while our most significant uses of operating cash flows are typically for our operating expenses, claims paid on our mortgage insurance policies and taxes. In addition, beginning with the launch of Radian Mortgage Capital in 2022, our operating activities also include purchases, sales and repayments of mortgage loans held for sale, which can fluctuate from period to period. The $141 million increase in cash provided by operating activities for 2023, as compared to 2022, was principally due to lower purchases of U.S. Mortgage Guaranty Tax and Loss Bonds and lower other operating expenses, partially offset by increases in net purchases of mortgage loans held for sale.

Investing Activities. Net cash used in investing activities increased in 2023, compared to 2022, primarily as a result of the combination of increased cash provided by operating activities and reduced cash used in financing activities, resulting in more cash available to invest. This increase in available cash to invest was primarily deployed in 2023 for purchases, net of sales and redemptions, of short-term investments.

Financing Activities. For 2023 and 2022, our primary financing activities included: (i) payments of dividends and (ii) repurchases of our common shares. The $214 million decrease in cash used in financing activities in 2023, as compared to 2022, was primarily due to lower share repurchases, partially offset by an increase in secured borrowings, primarily to help fund the increase in net purchases of mortgage loans held for sale. See Notes 12 and 14 of Notes to Consolidated Financial Statements for additional information regarding our borrowings and share repurchases, respectively.

See “Item 8. Financial Statements and Supplementary Data—Consolidated Statements of Cash Flows” for additional information.

Investment Portfolio

At December 31, 2023 and 2022, the following tables include $204 million and $112 million, respectively, of securities loaned to third-party borrowers under securities lending agreements, which are classified as other assets in our consolidated balance sheets.

Liquidity Analysis—Holding Company

Radian Group serves as the holding company for our operating subsidiaries and does not have any operations of its own. At December 31, 2023, Radian Group had available, either directly or through unregulated subsidiaries, unrestricted cash and liquid investments of $992 million. Available liquidity at December 31, 2023, excludes certain additional cash and liquid investments that have been advanced to Radian Group from our subsidiaries to pay for corporate expenses and interest payments. Total liquidity, which includes our undrawn $275 million unsecured revolving credit facility, as described below, was $1.3 billion as of December 31, 2023.

During 2023, Radian Group’s available liquidity increased by $90 million, due primarily to $400 million of ordinary dividends received from Radian Guaranty during the year, partially offset primarily by payments for dividends and share repurchases, as described below.

In addition to available cash and marketable securities, Radian Group’s principal sources of cash to fund future liquidity needs include: (i) payments made to Radian Group by its subsidiaries under expense- and tax-sharing arrangements; (ii) net investment income earned on its cash and marketable securities; and (iii) to the extent available, dividends or other distributions from its subsidiaries.

Radian Group has in place a $275 million unsecured revolving credit facility with a syndicate of bank lenders. The revolving credit facility matures in December 2026, although under certain conditions Radian Group may be required to offer to repay any outstanding amounts and terminate lender commitments earlier than the maturity date. Subject to certain limitations, borrowings under the credit facility may be used for working capital and general corporate purposes, including, without limitation, capital contributions to our insurance and other subsidiaries as well as growth initiatives. At December 31, 2023, the full $275 million remains undrawn and available under the facility. See Note 12 of Notes to Consolidated Financial Statements for additional information on the unsecured revolving credit facility.

In connection with our mortgage conduit, Radian Mortgage Capital has entered into the BMO Master Repurchase Agreement and the Goldman Sachs Master Repurchase Agreement, which, as of December 31, 2023, provide a combined uncommitted $250 million in mortgage loan repurchase facilities to finance the acquisition of residential mortgage loans and related mortgage loan assets. Most recently, in January 2024, Radian Mortgage Capital entered into the Flagstar Master Repurchase Agreement, increasing the uncommitted loan repurchase facilities to a combined $400 million through the Master Repurchase Agreements. Radian Group has entered into three separate Parent Guarantees to guaranty the obligations under the Master Repurchase Agreements. Under these Parent Guarantees, Radian Group is subject to negative and affirmative covenants customary for this type of financing transaction, including compliance with financial covenants that are generally consistent with the comparable covenants in the Company’s revolving credit facility. See Note 12 of Notes to Consolidated Financial Statements for additional information. In addition to financing the acquisition of mortgage loan assets under the Master Repurchase Agreements, Radian Mortgage Capital may fund such purchases directly using capital contributed from Radian Group.

We expect Radian Group’s principal liquidity demands for the next 12 months to be: (i) the payment of corporate expenses, including taxes; (ii) the payment of $450 million principal amount of our outstanding Senior Notes due 2024; (iii) interest payments on our outstanding debt obligations; (iv) the payment of quarterly dividends on our common stock, which were $0.225 per share in 2023 and subsequently increased to $0.245 for the first quarterly dividend in 2024, and which remain subject to approval by our board of directors and our ongoing assessment of our financial condition and potential needs related

91

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

to the execution and implementation of our business plans and strategies; (v) the potential continued repurchases of shares of our common stock pursuant to share repurchase authorizations, as described below; and (vi) investments to support our business strategy, including capital contributions to our subsidiaries. Liquidity demands may also include potential payments pursuant to the Parent Guarantees.

In addition to our ongoing short-term liquidity needs discussed above, our most significant need for liquidity beyond the next 12 months is the repayment of $975 million aggregate principal amount of our senior debt due in future years, including $525 million principal amount due in March 2025. See “Capitalization—Holding Company” below for details of our debt maturity profile. Radian Group’s liquidity demands for the next 12 months or in future periods could also include: (i) early repurchases or redemptions of portions of our debt obligations and (ii) additional investments to support our business strategy, including additional capital contributions to Radian Group’s subsidiaries. For additional information about related risks and uncertainties, see “Item 1A. Risk Factors,” including “Our sources of liquidity may be insufficient to fund our obligations.” and “Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity.” See also “Overview—Current Operating Environment” and Note 1 of Notes to Consolidated Financial Statements for further information.

In addition to Radian Group’s existing sources of liquidity to fund its obligations, we may decide to seek additional capital, including by incurring additional debt, issuing additional equity, or selling assets, which we may not be able to do on favorable terms, if at all.

Share Repurchases. During 2023 and 2022, the Company repurchased 5.3 million shares and 19.5 million shares of Radian Group common stock, respectively, under programs authorized by Radian Group’s board of directors, at a total cost of $133 million and $400 million, respectively, including commissions. See Note 14 of Notes to Consolidated Financial Statements for additional details on our share repurchase programs.

Dividends and Dividend Equivalents. Throughout 2023 and 2022, our quarterly dividend was $0.225 and $0.20 per share, respectively. In February 2024, Radian Group’s board of directors authorized an increase to our quarterly dividend from $0.225 to $0.245 per share. Based on our outstanding shares of common stock and RSUs, as of December 31, 2023, we expect to require approximately $150 million in the aggregate to pay dividends and dividend equivalents for the next 12 months. So long as no default or event of default exists under our revolving credit facility or the Parent Guarantees, Radian Group is not subject to any legal or contractual limitations on its ability to pay dividends except those generally applicable to corporations that are incorporated in Delaware. Delaware corporation law provides that dividends are only payable out of a corporation’s capital surplus or (subject to certain limitations) recent net profits. As of December 31, 2023, our capital surplus was $4.3 billion, representing our dividend limitation under Delaware law. The declaration and payment of future quarterly dividends remains subject to the board of directors’ discretion and determination.

Corporate Expenses and Interest Expense. Radian Group has expense-sharing arrangements in place with its principal operating subsidiaries that require those subsidiaries to pay their allocated share of certain holding-company-level expenses, including interest payments on Radian Group’s outstanding debt obligations. Corporate expenses and interest expense on Radian Group’s debt obligations allocated under these arrangements during 2023 of $164 million and $83 million, respectively, were substantially all reimbursed by its subsidiaries. We expect substantially all of our holding company expenses to continue to be reimbursed by our subsidiaries under our expense-sharing arrangements. The expense-sharing arrangements between Radian Group and its mortgage insurance subsidiaries, as amended, have been approved by the Pennsylvania Insurance Department, but such approval may be modified or revoked at any time.

Taxes. Pursuant to our tax-sharing agreements, our operating subsidiaries pay Radian Group an amount equal to any federal income tax the subsidiary would have paid on a standalone basis if they were not part of our consolidated tax return. As a result, from time to time, under the provisions of our tax-sharing agreements, Radian Group may pay to or receive from its operating subsidiaries amounts that differ from Radian Group’s consolidated federal tax payment obligation. During 2023, Radian Group received $16 million of tax-sharing agreement payments from its operating subsidiaries.

(1)Calculated as carrying value of senior notes, which were issued and are owed by our holding company, divided by carrying value of senior notes and stockholders’ equity. This holding company ratio does not include the effects of amounts owed by our subsidiaries related to secured borrowings.

Stockholders’ equity increased by $478 million from December 31, 2022, to December 31, 2023. The net increase in stockholders’ equity resulted primarily from: (i) our net income of $603 million and (ii) net unrealized gains on investments of $126 million. These items were partially offset by: (i) dividends of $146 million and (ii) share repurchases of $133 million, excluding related excise taxes due.

The increase in book value per share from $24.95 at December 31, 2022, to $28.71 at December 31, 2023, is primarily due to: (i) an increase of $3.84 per share attributable to our net income for 2023 and (ii) an increase of $0.80 per share due to an increase in unrealized gains in our available for sale securities, recorded in accumulated other comprehensive income. These increases were partially offset by a decrease of $0.93 per share attributable to dividends and dividend equivalents.

We regularly evaluate opportunities, based on market conditions, to finance our operations by accessing the capital markets or entering into other types of financing arrangements with institutional and other lenders. We also regularly consider various measures to improve our capital and liquidity positions, as well as to strengthen our balance sheet, improve Radian Group’s debt maturity profile and maintain adequate liquidity for our operations. Among other things, these measures may include borrowing agreements or arrangements, such as securities or other master repurchase agreements and revolving credit facilities. In the past we have repurchased or exchanged, prior to maturity, some of our outstanding debt, and in the future, we may from time to time seek to redeem, repurchase or exchange for other securities, or otherwise restructure or refinance some or all of our outstanding debt prior to maturity in the open market through other public or private transactions, including pursuant to one or more tender offers or through any combination of the foregoing, as circumstances may allow. The timing or amount of any potential transactions will depend on a number of factors, including market opportunities and our views regarding our capital and liquidity positions and potential future needs. There can be no assurance that any such transactions will be completed on favorable terms, or at all.

Mortgage Insurance

Historically, one of the primary demands for liquidity in our Mortgage Insurance business is the payment of claims, net of reinsurance, including from commutations and settlements. See Note 11 of Notes to Consolidated Financial Statements for information on our mortgage insurance reserve for losses and LAE, which represents our best estimate for the costs of settling future claims on currently defaulted mortgage loans.

Other principal demands for liquidity in our Mortgage Insurance business include: (i) expenses (including those allocated from Radian Group); (ii) repayments of FHLB advances; and (iii) taxes, including potential additional purchases of U.S. Mortgage Guaranty Tax and Loss Bonds. See Notes 10 and 16 of Notes to Consolidated Financial Statements for information related to these non-interest-bearing instruments. In addition to the foregoing liquidity demands, other payments have

93

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

included, and in the future could include, distributions from Radian Guaranty to Radian Group, including returns of capital or recurring ordinary dividends, as discussed below.

The principal sources of liquidity in our Mortgage Insurance business currently include insurance premiums, net investment income and cash flows from: (i) investment sales and maturities; (ii) FHLB advances; and (iii) if necessary, capital contributions from Radian Group. We believe that the operating cash flows generated by each of our mortgage insurance subsidiaries will provide these subsidiaries with the funds necessary to satisfy their needs for the foreseeable future.

As of December 31, 2023, Radian Guaranty maintained claims paying resources of $6.1 billion on a statutory basis, which consist of contingency reserves, statutory policyholders’ surplus, premiums received but not yet earned and loss reserves. In addition, our reinsurance programs are designed to provide additional claims-paying resources during times of economic stress and elevated losses. See Note 8 of Notes to Consolidated Financial Statements for additional information.

Radian Guaranty’s Risk-to-capital as of December 31, 2023, was 10.4 to 1. Radian Guaranty is not expected to need additional capital to satisfy state insurance regulatory requirements in their current form. At December 31, 2023, Radian Guaranty had statutory policyholders’ surplus of $620 million. This balance includes a $750 million benefit from U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury, which mortgage guaranty insurers such as Radian Guaranty may purchase in order to be eligible for a tax deduction, subject to certain limitations, related to amounts required to be set aside in statutory contingency reserves. See Note 16 of Notes to Consolidated Financial Statements and “Item 1A. Risk Factors” for more information.

Radian Guaranty currently is an approved mortgage insurer under the PMIERs. Private mortgage insurers, including Radian Guaranty, are required to comply with the PMIERs to remain approved insurers of loans purchased by the GSEs. At December 31, 2023, Radian Guaranty’s Available Assets under the PMIERs financial requirements totaled $5.9 billion, resulting in a PMIERs Cushion of $2.3 billion, or 62%, over its Minimum Required Assets. Those amounts compare to Available Assets and a PMIERs cushion of $5.6 billion and $1.7 billion, respectively, at December 31, 2022.

Our PMIERs Cushion as of December 31, 2023, includes the benefit from our reinsurance agreements through that date. Our PMIERs Cushion at December 31, 2023, also includes a benefit from the current broad-based application of the Disaster Related Capital Charge that has reduced the total amount of Minimum Required Assets that Radian Guaranty otherwise would have been required to hold against pandemic-related defaults by approximately $85 million and $200 million as of December 31, 2023 and 2022, respectively, taking into consideration our risk distribution structures in effect as of those dates. The application of the Disaster Related Capital Charge has reduced Radian Guaranty’s PMIERs Minimum Required Assets, but we expect this benefit will continue to diminish over time.

See “Item 1. Business—Regulation—Federal Regulation—GSE Requirements for Mortgage Insurance Eligibility” and “Radian Guaranty may fail to maintain its eligibility status with the GSEs, and the additional capital required to support Radian Guaranty’s eligibility could reduce our available liquidity” under “Item 1A. Risk Factors” for more information about the Disaster Related Capital Charge.

Despite holding assets above the minimum statutory capital thresholds and PMIERs financial requirements, the ability of Radian’s mortgage insurance subsidiaries to pay dividends on their common stock is restricted by certain provisions of the insurance laws of Pennsylvania, their state of domicile. Under Pennsylvania’s insurance laws, ordinary dividends and other distributions may only be paid out of an insurer’s positive unassigned surplus unless the Pennsylvania Insurance Department approves the payment of dividends or other distributions from another source.

Aided by the positive impacts of its merger with Radian Reinsurance in December 2022, Radian Guaranty had positive unassigned surplus of $258 million as of December 31, 2022, and continued to maintain positive unassigned surplus throughout 2023. As a result, beginning with the first quarter of 2023, Radian Guaranty had the ability to pay ordinary dividends, and paid total ordinary dividends of $400 million in cash and marketable securities in 2023. Subsequent to the payment of these dividends, as of December 31, 2023, Radian Guaranty had positive unassigned surplus of $120 million, and in February 2024, Radian Guaranty paid an ordinary dividend of $100 million in cash and marketable securities to Radian Group. Radian Guaranty expects to have the ability to continue paying ordinary dividends in 2024. See Note 16 of Notes to Consolidated Financial Statements for additional information on our statutory dividend restrictions and contingency reserve requirements.

Radian Guaranty is a member of the FHLB. As a member, it may borrow from the FHLB, subject to certain conditions, which include requirements to post collateral and to maintain a minimum investment in FHLB stock. Advances from the FHLB may be used to provide low-cost, supplemental liquidity for various purposes, including to fund incremental investments. Radian’s current strategy includes using FHLB advances as financing for general cash management and liquidity purposes. As of December 31, 2023, there were $95 million of FHLB advances outstanding. See Note 12 of Notes to Consolidated Financial Statements for additional information.

homegenius

As of December 31, 2023, our homegenius segment maintained cash and liquid investments totaling $64 million, including $46 million held by Radian Title Insurance.

94

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Title insurance companies, including Radian Title Insurance, are subject to comprehensive state regulations, including minimum net worth requirements. Radian Title Insurance was in compliance with all of its minimum net worth requirements at December 31, 2023. In the event the cash flows from operations of the homegenius segment are not adequate to fund all of its needs, including the regulatory capital needs of Radian Title Insurance, Radian Group may provide additional funds to the homegenius segment in the form of an intercompany note or other capital contribution, and if needed for Radian Title Insurance, subject to the approval of the Ohio Department of Insurance. Additional capital support may also be required for potential investments in new business initiatives to support our strategy of growing our businesses. During 2023 and 2022, Radian Group made $100 million and $65 million, respectively, of additional equity contributions to support its homegenius subsidiaries.

Liquidity levels may fluctuate depending on the levels and contractual timing of our invoicing and the payment practices of our homegenius clients, in combination with the timing of our homegenius segment’s payments for expenses. The amount, if any, and timing of the homegenius segment’s dividend paying capacity will depend primarily on the amount of excess cash flow generated by the segment.

Ratings

We believe that ratings independently assigned by third-party statistical rating organizations often are considered by others in assessing our credit strength and the financial strength of our primary insurance subsidiaries. Radian Group, Radian Guaranty and Radian Title Insurance are currently assigned the financial strength ratings set forth in the chart below, which are provided for informational purposes only and are subject to change. In “Item 1A. Risk Factors,” see “The current financial strength ratings assigned to our mortgage insurance subsidiaries could weaken our competitive position and potential downgrades by rating agencies to these ratings and the ratings assigned to Radian Group could adversely affect the Company.”

Critical Accounting Estimates

SEC guidance defines Critical Accounting Estimates as those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations of the registrant. These items require the application of management’s most difficult, subjective or complex judgments, often because of the need to make estimates about the effect of matters that are inherently uncertain and that may change in subsequent periods. In preparing our consolidated financial statements in accordance with GAAP, management has made estimates, assumptions and judgments that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

In preparing these financial statements, management has utilized available information, including our past history, industry standards and the current and projected economic and housing environments, among other factors, in forming its estimates, assumptions and judgments, giving due consideration to materiality. Because the use of estimates is inherent in GAAP, actual results could differ from those estimates. In addition, other companies may utilize different estimates, which may impact comparability of our results of operations to those of companies in similar businesses. A summary of the accounting estimates that management believes are critical to the preparation of our consolidated financial statements is set forth below. See Note 2 of Notes to Consolidated Financial Statements for additional disclosures regarding our significant accounting policies.

Mortgage Insurance Portfolio

Reserve for Losses and LAE

We establish reserves to provide for losses and LAE, which include the estimated costs of settling claims in our mortgage insurance portfolio, in accordance with the accounting standard regarding accounting and reporting by insurance enterprises. In our mortgage insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer that a borrower has missed two consecutive monthly mortgage payments. We maintain an extensive

95

Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

database of default and claim payment history, and use models based on a variety of loan characteristics to determine the likelihood that a default will reach claim status.

With respect to loans that are in default, considerable judgment is exercised as to the adequacy of reserve levels. We use an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. The Default to Claim Rate also includes our estimates with respect to expected Rescissions and Claim Denials, which have the effect of reducing our Default to Claim Rates. See Note 11 of Notes to Consolidated Financial Statements for the table detailing our Default to Claim Rate assumptions.

After estimating the Default to Claim Rate, we estimate Claim Severity based on recently observed severity rates within product type, type of insurance and Time in Default cohorts, as adjusted to account for anticipated differences in future results compared to recent trends. These severity estimates are then applied to individual loan coverage amounts to determine reserves. Similar to the Default to Claim Rate, Claim Severity also is impacted by the length of time that loans are in default and by our Loss Mitigation Activity. For claims under our Primary Mortgage Insurance, the coverage percentage is applied to the claim amount, which consists of the unpaid loan principal, plus past due interest (for which our liability is contractually capped in accordance with the terms of our Master Policies) and certain expenses associated with the default, to determine our maximum liability. Therefore, Claim Severity generally increases the longer that a loan is in default.

We considered the sensitivity of first-lien loss reserve estimates at December 31, 2023, by assessing the potential changes resulting from a parallel shift in Claim Severity and Default to Claim Rate estimates for primary loans, excluding any potential benefits from reinsurance. For example, assuming all other factors remain constant, for every one percentage point change in primary Claim Severity (which we estimate to be 98% of defaulted risk exposure at December 31, 2023), we estimated that our loss reserves would change by approximately $4 million at December 31, 2023. Assuming all other factors remain constant, for every one percentage point change in our overall primary net Default to Claim Rate (which we estimate to be 25% at December 31, 2023, including our assumptions related to Loss Mitigation Activities), we estimated a $14 million change in our loss reserves at December 31, 2023.

Senior management regularly reviews the modeled frequency, Claim Severity and Loss Mitigation Activity estimates, which are based on historical trends, as described above. If recent emerging or projected trends, including related to current and future macroeconomic conditions, differ significantly from the historical trends used to develop the modeled estimates, management evaluates these trends and determines how they should be considered in its reserve estimates.

Estimating our case reserve for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may prove to be inaccurate, especially during an extended economic downturn or a period of market volatility and economic uncertainty. These assumptions require management to use considerable judgment in estimating the rate at which these loans will result in claims and the amount of such claims. As such, there is uncertainty around our reserve estimate.

Premium Revenue Recognition

Premiums on mortgage insurance products are written on a recurring basis, either as monthly or annual premiums, or on a multi-year basis as a single premium. Monthly premiums written are earned as coverage is provided each month. For certain monthly policies where the billing is deferred for the first month’s coverage period, currently to the end of the policy, we record a net premium receivable representing the present value of such deferred premiums that we estimate will be collected at that future date.

We recognize changes in this receivable based on changes in the estimated amount and timing of such collections, including as a result of changes in observed trends as well as our periodic review of our servicing guide and our operations and collections practices. Key assumptions supporting our estimate of this net premium receivable, which equaled $36 million and $32 million as of December 31, 2023 and 2022, respectively, include a collection rate and average life. During both 2023 and 2022, we made no changes to these assumptions.

Single premiums written are initially recorded as unearned premiums and earned over time based on the anticipated loss pattern and the estimated period of risk exposure, which is primarily derived from historical experience and other factors such as projected losses, premium type and projected contractual periods of risk based on original LTV. Our estimate for the single premium earnings pattern is updated periodically and subject to change given uncertainty as to the underlying loss development and duration of risk. There were no significant changes to our single premium earnings pattern estimate in 2023 and 2022.

Actual future experience that is different than expected loss development or policy cancellations could result in further material increases or decreases in the recognition of net premiums earned. Based on historical experience, losses are relatively low during the first two years after a loan is originated and then increase over a period of several years before declining; however, several factors can impact and change this cycle, including the economic environment, the quality of the underwriting of the loan, characteristics of the mortgage loan, the credit profile of the borrower, housing prices and unemployment rates. If the timing of losses were to shift, it could accelerate or decelerate our recognition of net premiums earned and could have a material impact on our results of operations.

Financial Instruments

Fair Value

Our estimated fair value measurements are intended to reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Changes in economic conditions and capital market conditions, including but not limited to, benchmark interest rate changes, credit spread changes, market volatility and changes in the value of underlying collateral, could cause actual results to differ materially from our estimated fair value measurements.

Nearly all of our financial instruments recorded at fair value relate to our investment portfolio which, including securities loaned to third-party borrowers under securities lending agreements, totaled $6.3 billion as of December 31, 2023. The primary risks in our investment portfolio are interest-rate risk and credit-spread risk, namely the fair value sensitivity of our fixed income securities to changes in interest rates and credit spreads, respectively. We regularly analyze our exposure to interest-rate risk and credit-spread risk and have determined that the fair value of our investments is materially exposed to changes in both interest rates and credit spreads. For additional information regarding the sensitivity of our investment portfolio to these inputs, see “Item 7A. Quantitative and Qualitative Disclosures About Market Risk.”

See also Note 5 of Notes to Consolidated Financial Statements for additional information pertaining to financial instruments at fair value and our valuation methodologies.

Credit Losses and Other Impairments

We perform an evaluation of fixed-maturity securities available for sale each quarter to assess whether any decline in their fair value below cost is deemed to be a credit impairment recognized in earnings. Factors considered in our assessment for impairment include the extent to which the amortized cost basis is greater than fair value and the reasons for the decline in value. As of December 31, 2023, our gross unrealized losses on available for sale securities were $444 million, which can fluctuate materially over time based on changes in market conditions. See Note 6 of Notes to Consolidated Financial Statements for additional information regarding impairments related to investments.

Income Taxes

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance and this assessment is based on all available evidence, both positive and negative, and requires management to exercise judgment and make assumptions regarding whether such deferred tax assets will be realized in future periods. Future realization of our deferred tax assets will ultimately depend on the existence of sufficient taxable income of the appropriate character (ordinary income or capital gains) within the applicable carryback and carryforward periods provided under the tax law. In making our assessment of the more likely than not standard, the weight assigned to the effect of both positive and negative evidence is commensurate with the extent to which such evidence can be objectively verified.

We have determined that certain non-insurance entities within Radian may continue to generate taxable losses on a separate company basis in the near term and may not be able to fully utilize certain state and local NOLs on their state and local tax returns. Therefore, with respect to deferred tax assets relating to these state and local NOLs and other state timing adjustments, we retained a valuation allowance of $63 million and $70 million at December 31, 2023 and 2022, respectively.

Estimated factors in this assessment include, but are not limited to, forecasts of future income and actual and planned business and operational changes. An amount up to the total valuation allowance currently recorded could be recognized if our assessment of realizability changes. Our assumptions around these items and the weight assigned to them have remained consistent in recent periods. See Note 10 of Notes to Consolidated Financial Statements for additional information.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the potential for loss due to adverse changes in the value of financial instruments as a result of changes in market conditions. Examples of market risk include changes in interest rates, credit spreads, foreign currency exchange rates and equity prices. We perform sensitivity analyses to determine the effects of market risk exposures on our investment securities by determining the potential loss in future earnings, fair values or cash flows of market-risk-sensitive instruments resulting from one or more selected hypothetical changes in the above-mentioned market risks.

97

Part II. Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Interest-Rate Risk and Credit-Spread Risk

The primary market risks in our investment portfolio are interest-rate risk and credit-spread risk, namely the fair value sensitivity of our fixed income securities to changes in interest rates and credit spreads, respectively. We regularly analyze our exposure to interest-rate risk and credit-spread risk and have determined that the fair value of our investments is materially exposed to changes in both interest rates and credit spreads. As of December 31, 2023, we held $106 million of investment securities for trading purposes, representing less than 2% of our total investment portfolio. Accordingly, in presenting this discussion, we have not distinguished between trading and non-trading instruments.

We calculate the duration of our fixed income securities, expressed in years, in order to estimate the interest-rate sensitivity of these securities. The average duration of our total fixed income portfolio was 4.1 years and 4.4 years at December 31, 2023 and 2022, respectively. To assist us in setting duration targets for the investment portfolio, we analyze: (i) the interest-rate sensitivities of our liabilities, including prepayment risk associated with premium cash flows and credit losses; (ii) entity specific cash flows under various economic scenarios; (iii) return, volatility and correlation of specific asset classes and the interconnection with our liabilities; and (iv) our current risk appetite.

Our stress analysis for interest rates is based on the change in fair value of our fixed income securities, assuming a hypothetical instantaneous and parallel 100-basis point increase in the U.S. Treasury yield curve, with all other factors remaining constant. The carrying value of our fixed income securities has a balance of $6.1 billion and $5.6 billion as of December 31, 2023 and 2022, respectively. If interest rates experienced an increase of 100 basis points, our fixed income portfolio would decrease by $244 million and $236 million of the market value of the related fixed income portfolio for 2023 and 2022, respectively.

Credit spread represents the additional yield on a fixed income security, above the risk-free rate, that is paid by an issuer to compensate investors for assuming the credit risk of the issuer and market liquidity of the fixed income security. We manage credit-spread risk on both an entity and group level, across issuer, maturity, sector and asset class. Our stress analysis for credit-spread risk is based on the change in fair value of our fixed income securities, assuming a hypothetical 100-basis point increase in all credit spreads, with the exception of U.S. Treasury and agency RMBS obligations for which we have assumed no change in credit spreads, and assuming all other factors remain constant. If credit spreads experienced an increase of 100 basis points, our fixed income portfolio would decrease by $205 million and $201 million of the market value of the related fixed income portfolio for 2023 and 2022, respectively.

Actual shifts in credit spreads generally vary by issuer and security, based on issuer-specific and security-specific factors such as credit quality, maturity, sector and asset class. Within a given asset class, investment grade securities generally exhibit less credit-spread volatility than securities with lower credit ratings. At December 31, 2023, 95% of our investment portfolio was rated investment grade.

Our sensitivity analyses for interest-rate risk and credit-spread risk provide an indication of our investment portfolio’s sensitivity to shifts in interest rates and credit spreads. However, the timing and magnitude of actual market changes may differ from the hypothetical assumptions used in our sensitivity calculations.

Through our mortgage conduit, we also have exposure to market risks associated with our mortgage loan activities. For additional information on our mortgage loans held for sale, see Note 7 of Notes to Consolidated Financial Statements.

See “Item 1. Business—Investment Policy and Portfolio” for a discussion of portfolio strategy and risk exposure.

Securities Lending Agreements. Radian Group and Radian Guaranty from time to time enter into short-term securities lending agreements with third-party borrowers for the purpose of increasing the income on our investment securities portfolio with limited incremental risk. Market factors, including changes in interest rates, credit spreads and equity prices, may impact the timing or magnitude of cash outflows for the return of cash collateral. As of December 31, 2023 and 2022, the carrying value of these securities included in the sensitivity analyses above was $195 million and $85 million, respectively.

We also have the right to request the return of the loaned securities at any time. For additional information on our securities lending agreements, see Note 6 of Notes to Consolidated Financial Statements.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Radian Group Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Radian Group Inc. and its subsidiaries (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of operations, comprehensive income, changes in common stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2023, including the related notes and financial statement schedules listed in the index appearing under Item 15(a)3 (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023, and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of First-Lien Primary Case Reserves for Mortgage Insurance Policies

As described in Notes 2 and 11 to the consolidated financial statements, the Company establishes case reserves for losses on mortgage insurance policies for loans that are considered to be in default, as well as reserves for loss adjustment expenses and other reserves. As of December 31, 2023, first-lien primary case reserves were $344.2 million of the total $364.9 million of mortgage insurance loss reserves. Management’s estimate of the case reserves for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. Management uses an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. After estimating the Default to Claim Rate, management estimates Claim Severity based on the average of recently observed severity rates within product type, type of insurance, and Time in Default cohorts.

The principal considerations for our determination that performing procedures relating to the valuation of first-lien primary case reserves for mortgage insurance policies is a critical audit matter are (i) the significant judgment by management when developing their estimates of the Default to Claim Rates and Claim Severity, which in turn led to a high degree of auditor subjectivity and judgment in performing procedures relating to such estimates; (ii) the significant audit effort and subjectivity in evaluating the audit evidence related to the Default to Claim Rates and Claim Severity; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s valuation of first-lien primary case reserves for mortgage insurance policies, including controls over the development of the Default to Claim Rates and Claim Severity. These procedures also included, among others, the involvement of professionals with specialized skill and knowledge to assist in developing an independent estimate of the case reserves for first-lien primary mortgage insurance policies using actual historical data, comparing this independent estimate to management’s determined case reserves, and evaluating the reasonableness of management’s assumptions related to the Default to Claim Rates and Claim Severity. Performing these procedures involved testing the completeness and accuracy of data provided by management and independently developing Default to Claim Rates and Claim Severity assumptions based on data provided by management.

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

1. Description of Business

We are a mortgage and real estate company, providing both credit-related mortgage insurance coverage and an array of other mortgage, risk, title, real estate and real estate technology products and services. We have two reportable business segments—Mortgage Insurance and homegenius.

Mortgage Insurance

Our Mortgage Insurance segment provides credit-related insurance coverage for the benefit of mortgage lending institutions and mortgage credit investors, principally through private mortgage insurance on residential first-lien mortgage loans, and also offers other credit risk management solutions to our customers. We provide our mortgage insurance products and services mainly through our wholly owned subsidiary, Radian Guaranty.

Private mortgage insurance plays an important role in the U.S. housing finance system because it promotes affordable home ownership and helps protect mortgage lenders and mortgage investors, as well as other beneficiaries such as the GSEs, by mitigating default-related losses on residential mortgage loans. Generally, these loans are made to home buyers who make down payments of less than 20% of the purchase price for their home or, in the case of refinancings, have less than 20% equity in their home. Private mortgage insurance also facilitates the sale of these low down payment loans in the secondary mortgage market, almost all of which are currently sold to the GSEs.

Our total direct primary mortgage IIF and RIF were $270.0 billion and $69.7 billion, respectively, as of December 31, 2023, compared to $261.0 billion and $66.1 billion, respectively, as of December 31, 2022.

The GSEs and state insurance regulators impose various capital and financial requirements on our mortgage insurance subsidiaries. These include the PMIERs financial requirements, as well as Risk-to-capital and other risk-based capital measures and surplus requirements. Failure to comply with these capital and financial requirements may limit the amount of insurance that our mortgage insurance subsidiaries write or may prohibit them from writing insurance altogether. The GSEs and state insurance regulators possess significant discretion with respect to our mortgage insurance subsidiaries and all aspects of their business. See Note 16 for additional information on PMIERs and other regulatory information.

homegenius

Our homegenius segment is primarily a fee-for-service business that offers an array of products and services to market participants across the real estate value chain. Our homegenius products and services include title, real estate and real estate technology products and services offered primarily to consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees. These products and services help lenders, investors, consumers and real estate agents evaluate, manage, monitor, acquire and sell properties. They include proprietary platform-as-a-service solutions, as well as other services, such as real estate owned asset management, single-family rental services and real estate valuation services. In addition, we provide title insurance and non-insurance title, closing and settlement services to mortgage lenders, GSEs and mortgage investors, as well as directly to consumers for residential mortgage loans.

See Note 4 for additional information about our reportable segments and All Other business activities, which include the activities and investments associated with Radian Mortgage Capital.

Risks and Uncertainties

In assessing the Company’s current financial condition and developing forecasts of future operations, management has made significant judgments and estimates with respect to potential factors impacting our financial and liquidity position. These judgments and estimates are subject to risks and uncertainties that could affect amounts reported in our financial statements in future periods and that could cause actual results to be materially different from our estimates, including as a result of macroeconomic stresses such as inflation, slower economic growth and higher levels of unemployment.

2. Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation.

We generally refer to our insurance holding company alone, without its consolidated subsidiaries, as “Radian Group.” We refer to Radian Group together with its consolidated subsidiaries as “Radian,” the “Company,” “we,” “us” or “our,” unless the

108

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

context requires otherwise. Unless otherwise defined in this report, certain terms and acronyms used throughout this report are defined in the Glossary of Abbreviations and Acronyms included as part of this report.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of our contingent assets and liabilities at the dates of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. While the amounts included in our consolidated financial statements include our best estimates and assumptions, actual results may vary materially.

Investments

We group fixed-maturity securities in our investment portfolio into trading or available for sale securities. Trading securities are reported at fair value, with unrealized gains and losses reported as a separate component of income. Investments in fixed-maturity securities classified as available for sale are reported at fair value, with unrealized gains and losses (net of tax) reported as a separate component of stockholders’ equity as accumulated other comprehensive income (loss).

We also invest in several other types of investments including equity securities, which primarily consist of our interests in a variety of broadly diversified exchange traded funds and are recorded at fair value with unrealized gains and losses reported in income. Mortgage loans held for sale consist of residential mortgage loans, which we purchase with the intention of reselling and have elected to measure at fair value with unrealized gains and losses reported in income. Short-term investments are also carried at fair value and consist of money market instruments, certificates of deposit and highly liquid, interest-bearing instruments with an original maturity of 12 months or less at the time of purchase.

Amortization of premium and accretion of discount are calculated principally using the interest method over the term of the investment. Realized gains and losses on investments are recognized using the specific identification method. See Notes 5 and 6 for further discussion on investments.

We recognize an impairment as a loss for fixed-maturities available for sale on the consolidated statements of operations if: (i) we intend to sell the impaired security; (ii) it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis; or (iii) the present value of cash flows we expect to collect is less than the amortized cost basis of a security. In those instances, we record an impairment loss through earnings that varies depending on specific circumstances. If a sale is likely, the full amount of the impairment is recognized as a loss in the consolidated statements of operations. Otherwise, unrealized losses on securities are separated into: (i) the portion of loss that represents the credit loss and (ii) the portion that is due to other factors. In evaluating whether a decline in value for other securities relates to an existing credit loss, we consider several factors, including, but not limited to, the following:

■the extent to which the amortized cost basis is greater than fair value;

■reasons for the decline in value (e.g., adverse conditions related to industry or geographic area, changes in financial condition to the issuers or underlying loan obligors);

■any changes to the rating of the security by a rating agency;

■the failure of the issuer to make a scheduled payment;

■the financial position, access to capital and near-term prospects of the issuer, including the current and future impact of any specific events; and

■our best estimate of the present value of cash flows expected to be collected.

If a credit loss is determined to exist, the impairment amount is calculated as the difference between the amortized cost and the present value of future expected cash flows, limited to the difference between the carrying amount (i.e., fair value) and amortized cost. This credit loss impairment is included in net gains (losses) on investments and other financial instruments in the consolidated statements of operations, with an offset to an allowance for credit losses. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss impairment or a reversal of credit loss impairment.

Fair Value of Financial Instruments

Our estimated fair value measurements are intended to reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Changes in economic conditions and capital market conditions, including but not limited to, credit spread changes, benchmark interest rate changes, market volatility and changes in the value of underlying collateral, could cause actual results to differ materially from our estimated fair

109

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

value measurements. We define fair value as the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

In accordance with GAAP, which establishes a three-level valuation hierarchy, we disclose fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three levels of the fair value hierarchy are defined below:

Level I    —    Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level II    —    Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities; and

Level III    —    Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Level III inputs are used to measure fair value only to the extent that observable inputs are not available.

For markets in which inputs are not observable or are limited, we use significant judgment and assumptions that a typical market participant would use to evaluate the market price of an asset or liability. Given the level of judgment necessary, another market participant may derive a materially different estimate of fair value. These assets and liabilities are classified in Level III of our fair value hierarchy.

Available for sale securities, trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are recorded at fair value as described in Note 5. All changes in fair value of trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are included in our consolidated statements of operations.

Restricted Cash

Included in our restricted cash balances as of December 31, 2023 and 2022, were cash funds held in trusts for the benefit of certain counterparties, primarily as security for the payment and performance of the Company’s obligations.

Accounts and Notes Receivable

Accounts and notes receivable primarily consist of accrued premiums receivable, amounts billed and due from our customers for services performed, and certain receivables related to our reinsurance transactions. Accounts and notes receivable are carried at their estimated collectible amounts, net of any allowance for doubtful accounts, and are periodically evaluated for collectability based on past payment history and current economic conditions. See “Revenue Recognition—Mortgage Insurance” below for information on our deferred premiums and Note 8 for details on our reinsurance agreements.

Income Taxes

We provide for income taxes in accordance with the provisions of the accounting standard regarding accounting for income taxes. As required under this standard, our deferred tax assets and deferred tax liabilities are recognized under the balance sheet method, which recognizes the future tax effect of temporary differences between the amounts recorded in our consolidated financial statements and the tax bases of these amounts. Deferred tax assets and deferred tax liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the periods in which the deferred tax asset or deferred tax liability is expected to be realized or settled. In regard to accumulated other comprehensive income, the Company’s policy for releasing disproportionate income tax effects is to release the effects as individual items are sold.

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance. Our assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods.

See Note 10 for further discussion on income taxes.

Reserve for Losses and LAE

Mortgage Insurance

We establish reserves to provide for losses and LAE on our mortgage insurance policies, which include the estimated costs of settling claims, in accordance with the accounting standard regarding accounting and reporting by insurance enterprises (ASC 944). Although this standard specifically excludes mortgage insurance from its guidance relating to the

110

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

reserve for losses, because there is no specific guidance for mortgage insurance, we establish reserves for mortgage insurance as described below, using the guidance contained in this standard supplemented with other accounting guidance.

In our mortgage insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer. Case reserves for losses are established upon receipt of notification from servicers that a borrower has missed two monthly payments, which is when we consider a loan to be in default for financial statement and internal tracking purposes. We also establish reserves for associated LAE, consisting of the estimated cost of the claims administration process, including legal and other fees and expenses associated with administering the claims process.

We do not establish reserves for loans that are in default if we believe that we will not be liable for the payment of a claim with respect to that default. We generally do not establish loss reserves for expected future claims on insured mortgages that are not in default. See “Reserve for Premium Deficiency” below for an exception to these general principles.

With respect to loans that are in default, considerable judgment is exercised as to the adequacy of reserve levels. We use an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. The Default to Claim Rate also includes our estimates with respect to expected Loss Mitigation Activities, which have the effect of reducing our Default to Claim Rates.

After estimating the Default to Claim Rate, we estimate Claim Severity based on observed severity rates within product type, type of insurance and Time in Default cohorts. These severity estimates are then applied to individual loan coverage amounts to determine reserves.

Rescissions, Claim Denials and Claim Curtailments may occur for various reasons, including, without limitation, underwriting negligence, fraudulent applications and appraisals, breach of representations and warranties and inadequate documentation, primarily related to our insurance written in years prior to and including 2008. For our Loss Mitigation Activities, we incorporate a process referred to as a claims rebuttal process by which the insured or servicer of loans may challenge our decisions. Our estimate of future Loss Mitigation Activities incorporates our estimates of the likely outcomes of our claims rebuttal process based on historical practices.

Estimating our case reserve for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may not prove to be accurate, especially in the event of an extended economic downturn or a period of market volatility and economic uncertainty. These assumptions require management to use considerable judgment in estimating the rate at which these loans will result in claims and the amount of claims we expect to pay. As such, there is uncertainty around our reserve estimate.

Title Insurance

We establish reserves for estimated future claims payments on our title insurance policies at the time the related policy revenue is recorded. Our title insurance reserve for losses and LAE comprises estimates of both known claims and incurred but unreported claims expected to be paid in the future for policies issued as of the balance sheet date.

We provide for losses associated with these policies based upon our historical experience and other factors. However, by their nature, title claims can often be complex, vary greatly in dollar amounts, vary in number due to economic and market conditions such as an increase in mortgage foreclosures, and involve uncertainties as to ultimate exposure. Due to the length of time over which claim payments are made and regularly occurring changes in underlying economic and market conditions, these estimates are subject to variability.

Reserve for Premium Deficiency

Insurance enterprises are required to establish a premium deficiency reserve if the net present value of the expected future losses and expenses for a particular product line exceeds the net present value of expected future premiums and existing reserves for that product line. We reassess our expectations for premiums, losses and expenses for our mortgage insurance business at least quarterly and update our premium deficiency analyses accordingly. For our mortgage insurance business, we group our mortgage insurance products into two categories: first-lien and second-lien mortgage loans.

We did not require a first-lien or second-lien premium deficiency reserve as of December 31, 2023 or 2022.

Revenue Recognition

Mortgage Insurance

Premiums on mortgage insurance products are written on a recurring basis, either as monthly or annual premiums, or on a multi-year basis as a single premium. Monthly premiums written are earned as coverage is provided each month. For certain monthly policies where the billing is deferred for the first month’s coverage period, currently to the end of the policy, we record a net premium receivable representing the present value of such deferred premiums that we estimate will be collected at that

111

future date. As of December 31, 2023 and 2022, this net premium receivable was $36 million and $32 million, respectively, representing the present values of $81 million and $77 million, respectively, in contractual deferred monthly premiums, after adjustments for the estimated collectability and timing of future billing. We recognize changes in this receivable based on changes in the estimated amount and timing of such collections, including as a result of changes in observed trends as well as our periodic review of our servicing guide and our operations and collections practices. Given the difference between the present value of the net premium receivable recorded and the contractual premiums due, such changes to the preceding factors could have a material effect on our results of operations in future periods if any changes are implemented.

Annual premiums written are initially recorded as unearned premiums and amortized on a monthly, straight-line basis. Single premiums written are initially recorded as unearned premiums and earned over time based on the anticipated claim payment pattern, which includes historical industry experience and is updated periodically.

When we rescind insurance coverage on a loan, we refund all premiums received in connection with such coverage. When insurance coverage on a loan is canceled due to claim payment, we refund all premiums received since the date of delinquency. When insurance coverage is canceled for a reason other than Rescission or claim payment, all premium that is nonrefundable is immediately earned. Premium revenue is recognized net of our accrual for estimated premium refunds due to Rescissions, claim payments or other factors.

With respect to our reinsurance transactions, ceded premiums written on an annual or multi-year basis are initially set up as prepaid reinsurance and are amortized in a manner consistent with the recognition of income on direct premiums.

Title Insurance and Related Services

Title insurance premiums are recognized as revenue upon closing and completion of the real estate transaction. Premiums generally are calculated with reference to the policy amount. Premiums are charged to customers based on rates predetermined in coordination with each state’s respective Department of Insurance. Such regulations vary from state to state. Premium revenues from agency title operations are primarily comprised of premiums recognized upon title order and completion of real estate transaction closing.

Other title-related fees and income are closely related to title insurance premiums and are primarily associated with managing the closing of real estate transactions. As such, revenue is primarily recognized upon closing of the real estate transaction or completion and billing of services. We offer title services that include tax and title data services; centralized recording services; document retrieval; default curative title services; deed reports; property reports and other real estate or title-related activities. Expenses typically associated with premiums include third-party agent commissions and premium taxes.

Other Products and Services

We recognize revenue representing the transfer of services to customers in an amount that reflects the consideration that we expect to be entitled to receive in exchange for those services, which are recognized as the performance obligations are satisfied. Due to the transactional nature of our business, our services revenue may fluctuate from period to period as transactions are commenced or completed.

Our services and related revenue recognition considerations are primarily as follows:

Real Estate. We provide real estate services, including asset management and valuation services. Asset management services include management of the entire REO disposition process and services such as diligence and underwriting that serve the single-family rental asset class. In certain instances, fees are received at the time that an asset is assigned to Radian for management. These fees are recorded as deferred revenue and are recognized over time based on progress to date and the availability to customers. In addition, we offer a web-based asset management workflow solution to assist in managing REO assets, rental properties, due diligence for bulk acquisitions of multiple properties, loss mitigation efforts and short sales.

For valuation services, we leverage technology and a quality control process to deliver real estate valuation products and services to our customers, which include: appraisal review products; hybrid/ancillary appraisal products; automated valuation products; interactive valuation products; and broker price opinions. Each service qualifies as a separate performance obligation for which revenue is recognized as the service is performed and made available to the client.

Real Estate Technology. We are continuing to develop a growing suite of real estate technology products and services that are designed to facilitate real estate transactions and are provided as proprietary platform-as-a-service solutions. Revenues for these services are recognized over time as the service is provided and made available to the customer.

Mortgage Services. We provide third-party contract underwriting solutions to our mortgage customers. Generally, revenue is recognized when contract underwriting results are made available to the customer or when other related services are completed.

Cost of Services

Cost of services consists primarily of costs paid for employee compensation and related payroll benefits, as well as corresponding travel and related expenses, incurred in providing such services to clients.

Leases

We determine if an arrangement includes a lease at inception, and if it does, we recognize a right-of-use asset and lease liability. Right-of-use assets represent our right to use an underlying asset for the lease term and are recognized net of any payments made or received from the lessor. Lease liabilities represent our obligation to make lease payments and are based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date.

Lease expense is recognized on a straight-line basis over the expected lease term. Lease and non-lease components are generally not accounted for separately.

Our lease agreements primarily relate to operating leases for office space we use in our operations. Certain of our leases include renewal options and/or termination options that we did not consider in the determination of the right-of-use asset or the lease liability as we did not believe it was reasonably certain that we would exercise such options.

We assess our various asset groups, which include right-of-use assets, for changes in grouping and for potential impairment when certain events occur or when there are changes in circumstances, including potential alternative uses. If circumstances require a change in asset groupings or a right-of-use asset to be tested for possible impairment, and the carrying value of the right-of-use asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. See Notes 9 and 13 for additional information on our right-of-use assets and lease liabilities, respectively.

Reinsurance

We cede insurance risk through the use of reinsurance contracts and follow reinsurance accounting for those transactions where significant risk is transferred. Loss reserves and unearned premiums are established before consideration is given to amounts related to our reinsurance agreements.

In accordance with the terms of the QSR Program, rather than making a cash payment or transferring investments for ceded premiums written, Radian Guaranty holds the related amounts to collateralize the reinsurers’ obligations and has established a corresponding funds withheld liability. Any loss recoveries and any potential profit commission to Radian Guaranty will be realized from this account. The reinsurers’ share of earned premiums is paid from this account on a quarterly basis. For our Single Premium QSR Program, this liability also includes an interest credit on funds withheld, which is recorded as ceded premiums at a rate specified in the agreement and, depending on experience under the contract, may be paid to either Radian Guaranty or the reinsurers.

The ceding commission earned for premiums ceded pursuant to this transaction is attributable to other underwriting costs (including any related deferred policy acquisition costs). The unamortized portion of the ceding commission in excess of our related acquisition cost is reflected in other liabilities. Ceded premiums written are recorded on the balance sheet as prepaid reinsurance premiums and amortized to ceded premiums earned in a manner consistent with the recognition of income on direct premiums. See Note 8 for further discussion of our reinsurance transactions.

Variable Interest Entities

In connection with our reinsurance programs for our mortgage insurance business, we may enter into contracts with VIEs. VIEs include corporations, trusts or partnerships in which: (i) the entity has insufficient equity at risk to allow it to finance its activities without additional subordinated financial support or (ii) at-risk equity holders, as a group, do not have the characteristics of a controlling financial interest.

We perform an evaluation to determine whether we are required to consolidate the VIE’s assets and liabilities in our consolidated financial statements, based on whether we are deemed to be the primary beneficiary. The primary beneficiary of a VIE is the variable interest holder that is determined to have the controlling financial interest as a result of having both: (i) the power to direct the activities of a VIE that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses or right to receive benefits from the VIE that potentially could be significant to the VIE. See Note 8 for additional information.

Goodwill and Other Acquired Intangible Assets, Net

Goodwill is an asset representing the estimated future economic benefits arising from the assets we have acquired that were not individually identified and separately recognized. Goodwill is deemed to have an indefinite useful life and is subject to review for impairment annually, or more frequently whenever circumstances indicate potential impairment at the reporting unit

113

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

level. A reporting unit represents a business for which discrete financial information is available. We have concluded that we have one reporting unit, our homegenius segment, for purposes of our goodwill impairment assessment. We generally perform our annual goodwill impairment test during the fourth quarter of each year, comparing the carrying value of the reporting unit as of the prior quarter to its estimated fair value. An impairment charge is recognized for any excess of the reporting unit’s carrying amount over the reporting unit’s estimated fair value, up to the full amount of the goodwill allocated to the reporting unit.

The following table shows the changes in the carrying amount of goodwill for the period indicated, which reflect the results of our impairment testing in the fourth quarter of 2023.

Rollforward of goodwill
(In thousands)	Goodwill		Accumulated Impairment Losses		Net
Balance at December 31, 2022	$	9,802	$	—	$	9,802
Impairment losses	—		(9,802)		(9,802)
Balance at December 31, 2023	$	9,802	$	(9,802)	$	—

The calculation of the estimated fair value of goodwill is performed primarily using an income approach and requires the use of significant estimates and assumptions that are highly subjective in nature, such as future expected cash flows, discount rates, attrition rates and market conditions. Included in our estimates and assumptions is the impact of current year profitability, estimated future cash flows and, to a lesser extent, observed competitor declining trends.

The sustained inflationary pressures and higher interest rate environment have negatively impacted our homegenius businesses, resulting in losses due primarily to the decline in industry-wide purchase and refinance volumes. Despite steps taken to align our workforce to the current and expected needs of the business and reduce our operating expenses, we expect this trend to continue to impact the results of our homegenius segment in at least the near-term based on current market conditions and our expectation that overall refinance volumes will remain low. As a result of our updated financial forecast completed in the fourth quarter of 2023 and based on our annual goodwill impairment assessment in the fourth quarter of 2023, we recorded an impairment of the outstanding balance of $10 million. As a result of this impairment, there was no remaining goodwill balance at December 31, 2023.

Our acquired intangible assets, other than goodwill, primarily consist of customer relationships and represent the value of the specifically acquired customer relationships. For financial reporting purposes, intangible assets with finite lives are amortized over their applicable estimated useful lives in a manner that approximates the pattern of expected economic benefit from each intangible asset. All of our other acquired intangible assets have now been fully amortized and, as such, there was no remaining other acquired intangible asset balance at December 31, 2023.

The following is a summary of the gross and net carrying amounts and accumulated amortization (including impairment) of our other acquired intangible assets as of the periods indicated.

Other acquired intangible assets
	December 31, 2023						December 31, 2022
(In thousands)	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Client relationships	$	43,550	$	(43,550)	$	—	$	43,550	$	(38,067)	$	5,483

Property and Equipment

We capitalize certain costs associated with the development of internal-use software and the purchase of property and equipment. Software, property and equipment are carried at cost, net of accumulated depreciation and amortization. Amortization and depreciation are calculated on a straight-line basis over the estimated useful life of the respective assets and commence during the month of our placement of the assets into use.

The estimated useful life used to calculate the amortization of internal-use software is generally seven years. Leasehold improvements are depreciated over the lesser of the estimated useful life of the asset improved or the remaining term of the lease. The estimated useful life used to calculate the depreciation of furniture and equipment is generally three years. Depreciation and amortization expense associated with property and equipment was $15 million for both the years ended December 31, 2023 and 2022, and $16 million for the year ended December 31, 2021.

Deferred Policy Acquisition Costs

Incremental, direct costs associated with the successful acquisition of mortgage insurance policies, consisting of compensation, premium tax and other policy issuance and underwriting expenses, are initially deferred and reported as deferred policy acquisition costs. Consistent with industry accounting practice, amortization of these costs for each underwriting year book of business is recognized in proportion to estimated gross profits over the estimated life of the policies.

Estimated gross profits are composed of earned premium, interest income, losses and LAE. Estimates of expected gross profit, including the Persistency Rate and loss development assumptions for each underwriting year used as a basis for amortization, are evaluated quarterly and the total amortization recorded to date is adjusted by a charge or credit to our consolidated statements of operations if actual experience or other evidence suggests that previous estimates should be revised. Considerable judgment is used in evaluating these estimates and the assumptions on which they are based. The use of different assumptions may have a significant effect on the amortization of deferred policy acquisition costs.

Ceding commissions received under our reinsurance arrangements related to these costs are also deferred and accounted for using similar assumptions. See Note 8 for additional information.

Earnings Per Share

Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, while diluted net income per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and the weighted-average number of dilutive potential common shares.

Dilutive potential common shares relate primarily to our share-based compensation arrangements. In computing diluted net income per share, we use the treasury stock method, which is computed by assuming the issuance of common stock for the potential dilution of our unvested RSUs. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income.

Share-Based Compensation

The cost related to share-based equity instruments is measured based on the grant-date fair value at the date of issuance, which for RSU awards is primarily determined by our common stock price on the date of grant. For share-based awards with performance conditions related to our own operations, the expense recognized is dependent on the probability of the performance measure being achieved. Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. Any forfeitures of awards are recognized as they occur. See Note 17 for further information.

4. Segment Reporting

We have two strategic business units that we manage separately—Mortgage Insurance and homegenius. Our Mortgage Insurance segment derives its revenue from mortgage insurance and other mortgage and risk services, including contract underwriting solutions provided to mortgage lending institutions and mortgage credit investors. Our homegenius segment offers an array of title, real estate and real estate technology products and services to consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees.

In addition, we report as All Other activities that include: (i) income (losses) from assets held by Radian Group, our holding company; (ii) related general corporate operating expenses not attributable or allocated to our reportable segments; and (iii) certain new business opportunities and other immaterial activities, the majority of which are currently activities associated with our mortgage conduit business conducted through Radian Mortgage Capital.

We allocate corporate operating expenses to our reportable segments and other immaterial operating segments included in All Other based primarily on each segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of management time spent on each segment. In addition, we allocate all corporate interest expense to our Mortgage Insurance segment, due to the capital-intensive nature of our mortgage insurance business. We do not manage assets by segment.

See Note 1 for additional details about our Mortgage Insurance and homegenius businesses.

Adjusted Pretax Operating Income (Loss)

Our senior management, including our Chief Executive Officer (Radian’s chief operating decision maker), uses adjusted pretax operating income (loss) as our primary measure to evaluate the fundamental financial performance of each of Radian’s business segments and to allocate resources to the segments.

Adjusted pretax operating income (loss) is defined as pretax income (loss) excluding the effects of: (i) net gains (losses) on investments and other financial instruments, except for certain investments and other financial instruments attributable to our reportable segments and All Other activities; (ii) amortization and impairment of goodwill and other acquired intangible assets; and (iii) impairment of other long-lived assets and other non-operating items, if any, such as gains (losses) from the sale of lines of business, acquisition-related income and expenses and gains (losses) on extinguishment of debt.

Although adjusted pretax operating income (loss) excludes certain items that have occurred in the past and are expected to occur in the future, the excluded items represent those that are: (i) not viewed as part of the operating performance of our primary activities or (ii) not expected to result in an economic impact equal to the amount reflected in pretax income (loss). These adjustments, along with the reasons for their treatment, are described below.

(1) Net gains (losses) on investments and other financial instruments. The recognition of realized investment gains or losses can vary significantly across periods as the activity is highly discretionary based on the timing of individual securities sales due to such factors as market opportunities, our tax and capital profile and overall market cycles. Unrealized gains and losses arise primarily from changes in the market value of our investments that are classified as trading or equity securities. These valuation adjustments may not necessarily result in realized economic gains or losses.

Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these realized and unrealized gains or losses and changes in fair value of other financial instruments. Except for certain investments and other financial instruments attributable to our reportable segments and All Other activities, we do not view them to be indicative of our fundamental operating activities.

(2)Amortization and impairment of goodwill and other acquired intangible assets. Amortization of acquired intangible assets represents the periodic expense required to amortize the cost of acquired intangible assets over their estimated useful lives. Acquired intangible assets are also periodically reviewed for potential impairment, and impairment adjustments are made whenever appropriate. We do not view these charges as part of the operating performance of our primary activities.

(3)Impairment of other long-lived assets and other non-operating items, if any. Impairment of other long-lived assets and other non-operating items includes activities that we do not view to be indicative of our fundamental operating activities, such as: (i) impairment of internal-use software and other long-lived assets; (ii) gains (losses) from the sale of lines of business; (iii) acquisition-related income and expenses; and (iv) gains (losses) on extinguishment of debt.

Valuation Methodologies for Assets Measured at Fair Value

We are responsible for the determination of the value of all investments carried at fair value and the supporting methodologies and assumptions. To assist us in this responsibility, we utilize independent third-party valuation service providers to gather, analyze and interpret market information and estimate fair values based upon relevant methodologies and assumptions for various asset classes and individual securities.

We perform monthly quantitative and qualitative analyses on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. Our analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) a comparison of pricing services’ valuations to other independent sources; (iii) a review of month-to-month price fluctuations; and (iv) a comparison of actual purchase and sale transactions with valuations received from third parties. These processes are designed to ensure that our investment values are accurately recorded, that the data inputs and valuation techniques utilized are appropriate and consistently applied and that the assumptions are reasonable and consistent with the objective of determining fair value.

The following are descriptions of our valuation methodologies for financial assets measured at fair value.

U.S. Government and Agency Securities. The fair value of U.S. government and agency securities is estimated using observed market transactions, including broker-dealer quotes and actual trade activity as a basis for valuation. U.S. government and agency securities are categorized in either Level I or Level II of the fair value hierarchy.

State and Municipal Obligations. The fair value of state and municipal obligations is estimated using recent transaction activity, including market observations. Valuation models are used, which incorporate bond structure, yield curve, credit spreads and other factors. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable.

Money Market Instruments. The fair value of money market instruments is based on daily prices, which are published and available to all potential investors and market participants. As such, these securities are categorized in Level I of the fair value hierarchy.

Corporate Bonds and Notes. The fair value of corporate bonds and notes is estimated using recent transaction activity, including market observations. Spread models are used that incorporate issuer and structure characteristics, such as credit risk and early redemption features, where applicable. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable.

Asset-backed and Mortgage-backed Securities. The fair value of these instruments, which include RMBS, CMBS, CLO, Other ABS and mortgage insurance-linked notes, is estimated based on prices of comparable securities and spreads and observable prepayment speeds. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable. The fair value of any Level III securities is generally estimated by discounting estimated future cash flows.

Foreign Government and Agency Securities. The fair value of foreign government and agency securities is estimated using observed market yields used to create a maturity curve and observed credit spreads from market makers and broker-dealers. These securities are categorized in Level II of the fair value hierarchy.

Equity Securities. The fair value of these securities is generally estimated using observable market data in active markets or bid prices from market makers and broker-dealers. Generally, these securities are categorized in Level I or II of the fair value hierarchy, as observable market data are readily available. Certain equity securities may be categorized in Level III of the fair value hierarchy due to a lack of market-based transaction data or the use of model-based valuations.

Mortgage Loans Held for Sale. The fair value of these mortgage loans is generally estimated using measurements derived from observable market data, adjusted for certain loan-level factors such as loan type, loan amount, note rate, LTV, and expected exit value of the loan. As such, these loans are generally categorized in Level II of the fair value hierarchy.

Other Investments. These securities primarily consist of commercial paper and short-term certificates of deposit, which are categorized in Level II of the fair value hierarchy. The fair value of these investments is estimated using market data for comparable instruments of similar maturity and average yield.

Other Invested Assets. These assets consist of interests in private debt or equity investments. The estimated fair value of these other invested assets is primarily based on the private company’s performance, as well as the terms of the instrument and general market benchmarks. As such, these investments are categorized in Level III of the fair value hierarchy.

123

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

Derivative Assets and Liabilities. These instruments include embedded derivatives related to our XOL Program, which are categorized in Level III of the fair value hierarchy. The fair value of these derivatives reflects the present value impact of the variation in investment income on the assets held by the reinsurance trusts and the contractual reference rate used to calculate the reinsurance premiums we will pay. Beginning in 2022, our derivative assets and liabilities also include the fair value of certain forward mortgage loan commitments as well as hedging instruments used to manage interest rate risk related to our investments in mortgage loans held for sale. The Company’s derivative instruments are not designated as accounting hedging instruments, and therefore, changes in fair value are recorded in our consolidated statements of operations. These derivative assets and liabilities are categorized in either Level II or III of the fair value hierarchy.

The fair value of our senior notes is estimated based on quoted market prices. The fair value of our secured borrowings is estimated based on current market rates and contractual cash flows, including for FHLB advances, any fees that may be required to be paid to the FHLB. These liabilities are categorized in Level II of the fair value hierarchy. See Note 12 for further information about our senior notes and secured borrowings.

There were 1,063 and 1,284 securities in an unrealized loss position at December 31, 2023 and 2022, respectively. We determined that these unrealized losses were due to non-credit factors and that, as of December 31, 2023, we did not expect to realize a loss for our investments in an unrealized loss position given our intent and ability to hold these investment securities until recovery of their amortized cost basis. See Note 2 for information regarding our accounting policy for impairments of investments.

Loaned Securities

We participate in a securities lending program whereby we loan certain securities in our investment portfolio to third-party borrowers for short periods of time. These securities lending agreements are collateralized financing arrangements whereby we transfer securities to third parties through an intermediary in exchange for cash or other securities. However, pursuant to the terms of these agreements, we maintain effective control over all loaned securities. Although we report such securities at fair value within other assets in our consolidated balance sheets, rather than within investments, the detailed information we provide in this Note 6 includes these securities. See Note 5 for additional detail on the loaned securities.

Under our securities lending agreements, the borrower is required to provide to us collateral, consisting of cash or securities, in amounts generally equal to or exceeding: (i) 102% of the value of the loaned securities (105% in the case of foreign securities) or (ii) another agreed-upon percentage not less than 100% of the market value of the loaned securities. Any cash collateral we receive may be invested in liquid assets. Cash collateral, which is reinvested for our benefit by the intermediary in accordance with the investment guidelines contained in the securities lending and collateral agreements, is

126

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

reflected in short-term investments, with an offsetting liability recognized in other liabilities for the obligation to return the cash collateral. Securities collateral we receive is held on deposit for the borrower’s benefit and we may not transfer or loan such securities collateral unless the borrower is in default. Therefore, such securities collateral is not reflected in our consolidated financial statements given that the risks and rewards of ownership are not transferred to us from the borrowers.

Fees received and paid in connection with securities lending agreements are recorded in net investment income on the consolidated statements of operations.

All of our securities lending agreements are classified as overnight and revolving. Securities collateral on deposit with us from third-party borrowers totaling $61 million and $16 million as of December 31, 2023 and 2022, respectively, may not be transferred or re-pledged unless the third-party borrower is in default, and is therefore not reflected in our consolidated financial statements.

7. Mortgage Loans Held for Sale

The carrying value of mortgage loans held for sale owned by Radian Mortgage Capital totaled $33 million and $4 million at December 31, 2023 and 2022, respectively, and is based on fair value. The estimated fair value of our mortgage loans held for sale is subject to changes in mortgage interest rates from the closing or purchased date through the date of the sale into the secondary market. We elected the fair value option for our mortgage loans held for sale to mitigate income statement volatility and allow for consistent treatment of both loans and any associated hedges or derivatives. Net gains (losses) associated with our mortgage loans held for sale and any related hedges are included in net gains (losses) on investments and other financial instruments on our consolidated statements of operations. See Note 5 for additional information about the fair value of these financial instruments.

As of December 31, 2023, our mortgage loans held for sale consisted of 72 mortgage loans with a total unpaid principal balance of $32 million, related to properties in 24 states and the District of Columbia. As of December 31, 2023, none of these loans were greater than ninety days delinquent or in nonaccrual status. Interest earned on mortgage loans held for sale is included in net investment income on our consolidated statements of operations.

Further, as of December 31, 2023, the Company had commitments to purchase and fund additional mortgage loans with a total unpaid principal balance of $84 million. Prior to the settlement and funding of these loan purchases, any unrealized net gains (losses) related to these commitments are recorded as derivative assets or liabilities on our consolidated balance sheets.

The following table reflects the outstanding derivative instruments used to hedge our mortgage loan activity as of the dates indicated.

We primarily fund the purchases of our mortgage loans held for sale with amounts borrowed under our mortgage loan financing facilities. Expenses related to these facilities are included in interest expense on our consolidated statements of operations. See Note 12 for additional information on these facilities and their related terms and covenants.

Net investment income earned on the mortgage loans held for sale and interest expense incurred on the mortgage loan financing facilities consisted of the following.

In addition to the debt covenants under its financing facilities, Radian Mortgage Capital is also subject to certain requirements established by state and other regulators and loan purchasers, including Freddie Mac, such as certain minimum net worth and capital requirements. The most restrictive of these requirements requires Radian Mortgage Capital to maintain a minimum tangible net worth of $3 million. To the extent these requirements are not met, these parties may exercise certain remedies, which may include, as applicable, prohibiting Radian Mortgage Capital from purchasing, selling, or servicing loans. As of December 31, 2023, Radian Mortgage Capital was in compliance with all such requirements.

8. Reinsurance

In our mortgage insurance and title insurance businesses, we use reinsurance as part of our risk distribution strategy, including to manage our capital position and risk profile. The reinsurance arrangements for our mortgage insurance business include premiums ceded under the QSR Program and the XOL Program. The amount of credit that we receive under the PMIERs financial requirements for our third-party reinsurance transactions is subject to ongoing review and approval by the GSEs.

QSR Program

2023 and 2022 QSR Agreements

Radian Guaranty entered into each of the 2023 and 2022 QSR Agreements with panels of third-party reinsurance providers to cede a contractual quota share percentage of certain of our NIW, which includes both Recurring Premium Policies and Single Premium Policies (as set forth in the table below), subject to certain conditions, including a limitation for the 2023 QSR Agreement on ceded RIF equal to $3.0 billion over the term of the agreement.

Radian Guaranty receives a ceding commission for ceded premiums earned pursuant to these transactions. Radian Guaranty is also entitled to receive a profit commission quarterly, subject to a final annual re-calculation, provided that the loss ratio on the loans covered under the agreements generally remains below the applicable prescribed thresholds. Losses on the ceded risk up to these thresholds reduce Radian Guaranty’s profit commission on a dollar-for-dollar basis.

Radian Guaranty may discontinue ceding new policies under the 2023 QSR Agreement at the end of any calendar quarter. As of July 1, 2023, Radian Guaranty is no longer ceding NIW under the 2022 QSR Agreement.

Single Premium QSR Program

Radian Guaranty entered into each of the 2016 Single Premium QSR Agreement, 2018 Single Premium QSR Agreement and 2020 Single Premium QSR Agreement with panels of third-party reinsurers to cede a contractual quota share percentage of our Single Premium NIW as of the effective date of each agreement (as set forth in the table below), subject to certain conditions.

Radian Guaranty receives a ceding commission for ceded premiums written pursuant to these transactions. Radian Guaranty also receives a profit commission annually, provided that the loss ratio on the loans covered under the agreement

131

generally remains below the applicable prescribed thresholds. Losses on the ceded risk up to these thresholds reduce Radian Guaranty’s profit commission on a dollar-for-dollar basis.

As of January 1, 2022, Radian Guaranty is no longer ceding NIW under the Single Premium QSR Program.

2012 QSR Agreements

In 2012, Radian Guaranty entered into the 2012 QSR Agreements with a third-party reinsurance provider. Radian Guaranty has ceded the maximum amount permitted under the 2012 QSR Agreements and is no longer ceding NIW under this program. RIF ceded under the 2012 QSR Agreements was $100 million and $142 million as of December 31, 2023 and 2022, respectively.

The following table sets forth additional details regarding the QSR Program, with RIF ceded as of the dates indicated.

(2)Radian Guaranty has the option, based on certain conditions and subject to a termination fee, to terminate any of the agreements at the end of any calendar quarter on or after the applicable optional termination date. If Radian Guaranty exercises this option in the future, it would result in Radian Guaranty reassuming the related RIF in exchange for a net payment to the reinsurers calculated in accordance with the terms of the applicable agreement. Radian Guaranty also may terminate any of the agreements prior to the scheduled termination date under certain circumstances, including if one or both of the GSEs no longer grant full PMIERs credit for the reinsurance.

XOL Program

Mortgage Insurance-linked Notes

Radian Guaranty has entered into a number of fully collateralized reinsurance arrangements with the Eagle Re Issuers, as described below. For the respective coverage periods, Radian Guaranty retains the first-loss layer of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amounts. The Eagle Re Issuers provide second layer coverage up to the outstanding coverage amounts. For each of these reinsurance arrangements, the Eagle Re Issuers financed their coverage by issuing mortgage insurance-linked notes to eligible capital markets investors in unregistered private offerings.

The aggregate excess-of-loss reinsurance coverage for these arrangements decreases over the maturity period of the mortgage insurance-linked notes (either a 10-year or 12.5-year period depending on the transaction) as the principal balances of the underlying covered mortgages decrease and as any claims are paid by the applicable Eagle Re Issuer or the mortgage insurance is canceled. Radian Guaranty has rights to terminate the reinsurance agreements upon the occurrence of certain events, including an optional call feature that provides Radian Guaranty the right to terminate the transaction on or after the optional call date (5 or 7 years after the issuance of the mortgage insurance-linked notes depending on the transaction) and a right to exercise an optional clean-up call if the outstanding principal amount of the related mortgage insurance-linked notes falls below 10% of the initial coverage level or principal balance, depending on the transaction, of the related mortgage insurance-linked notes.

132

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

Under each of the reinsurance agreements, the outstanding reinsurance coverage amount will begin amortizing after an initial period in which a target level of credit enhancement is obtained and will stop amortizing if certain thresholds, or triggers, are reached, including a delinquency trigger event based on an elevated level of delinquencies as defined in the related mortgage insurance-linked notes transaction agreements.

Given the diminished PMIERs capital benefit and risk mitigation values that Radian Guaranty was receiving from the reinsurance agreements, in June 2023 Eagle Re 2019-1 Ltd. and Eagle Re 2020-1 Ltd. conducted tender offers to purchase the mortgage insurance-linked notes that supported their reinsurance agreements with Radian Guaranty. As a result of the tender offers, $455 million and $332 million of the original principal amount of the Eagle Re 2019-1 Ltd. and Eagle Re 2020-1 Ltd. mortgage insurance-linked notes, respectively, were tendered and repurchased, representing 100% of the Eagle Re 2019-1 Ltd. mortgage insurance-linked notes and 82% of the Eagle Re 2020-1 Ltd. mortgage insurance-linked notes. The corresponding portion of the reinsurance agreements supported by the tendered notes were terminated.

As a result of these tender offers in 2023, Radian Guaranty incurred additional ceded premiums earned of $21 million, consisting of $16 million related to the cost of tender premiums and associated expenses and $5 million related to the acceleration of deferred costs from the original executions of these transactions. Based on projections and expectations in June 2023 at the time of the tender offers, Radian Guaranty expected to save approximately $58 million of future ceded premiums over time as a result of these tenders, including a full recovery of the $21 million of upfront one-time costs noted above within one year.

Upon reaching the five-year optional call date, in November 2023, Radian Guaranty exercised its right to terminate Radian Guaranty’s excess-of-loss reinsurance agreement with Eagle Re 2018-1 Ltd. In connection with the termination of Radian Guaranty’s excess-of-loss reinsurance agreement with Eagle Re 2018-1 Ltd., the mortgage insurance-linked notes issued by Eagle Re 2018-1 Ltd. were redeemed in full with a distribution of remaining collateral assets.

Traditional Reinsurance

For the respective coverage periods under traditional XOL reinsurance agreements, Radian Guaranty retains the first-loss layer of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amounts. The reinsurers provide second layer coverage up to the outstanding coverage amounts. Radian Guaranty is then responsible for any losses in excess of the reinsurance coverage amount.

The 2023 XOL Agreement, which was executed in October 2023, is scheduled to terminate September 30, 2033. Radian Guaranty has the option, based on certain conditions, to terminate the agreement as of September 30, 2028, or at the end of any calendar quarter thereafter, which would result in Radian Guaranty reassuming the related RIF. In the event Radian Guaranty does not exercise its right to terminate the agreement on September 30, 2028, the monthly premium rate will increase from the original monthly premium.

(1)Excludes Eagle Re 2019-1 Ltd. and Eagle Re 2018-1 Ltd., which as further discussed above, were terminated in June 2023 and November 2023, respectively.

(2)Radian Group purchased $45 million of Eagle Re 2021-1 Ltd. and $2 million of Eagle Re 2020-1 Ltd. outstanding principal amounts of the respective mortgage insurance-linked notes issued in connection with these reinsurance transactions. These notes are included in fixed-maturities available for sale on our consolidated balance sheets at December 31, 2023 and 2022. See Notes 5 and 6 for additional information.

The Eagle Re Issuers are not subsidiaries or affiliates of Radian Guaranty. Based on the accounting guidance that addresses VIEs, we have not consolidated any of the assets and liabilities of the Eagle Re Issuers in our financial statements, because Radian does not have: (i) the power to direct the activities that most significantly affect the Eagle Re Issuers’ economic performances or (ii) the obligation to absorb losses or the right to receive benefits from the Eagle Re Issuers that potentially could be significant to the Eagle Re Issuers. See Note 2 for more information on our accounting treatment of VIEs.

Following the discontinuation of the London Inter-bank Offered Rate (LIBOR), effective June 30, 2023, SOFR is the effective benchmark rate for all of our reinsurance agreements with the Eagle Re Issuers as of December 31, 2023. The reinsurance premium due to the Eagle Re Issuers is calculated by multiplying the outstanding reinsurance coverage amount at the beginning of a period by a coupon rate, which is the sum of SOFR, plus a contractual risk margin, and then subtracting actual investment income collected on the assets in the reinsurance trust during the preceding month. As a result, the premiums we pay will vary based on: (i) the spread between SOFR and the rates on the investments held by the reinsurance trust and (ii) the outstanding amount of reinsurance coverage.

As the reinsurance premium will vary based on changes in these rates, we concluded that the reinsurance agreements contain embedded derivatives, which we have accounted for separately as freestanding derivatives and recorded in other assets or other liabilities on our consolidated balance sheets. Changes in the fair value of these embedded derivatives are recorded in net gains (losses) on investments and other financial instruments on our consolidated statements of operations. See Note 5 herein for more information on our fair value measurements of financial instruments, including our embedded derivatives.

In the event an Eagle Re Issuer is unable to meet its future obligations to us, if any, our insurance subsidiaries would be liable to make claims payments to our policyholders. In the event that all of the assets in the reinsurance trust (consisting of U.S. government money market funds, cash or U.S. Treasury securities) become worthless and the Eagle Re Issuer is unable to make its payments to us, our maximum potential loss would be the amount of mortgage insurance claim payments for losses on the insured policies, net of the aggregate reinsurance payments already received, up to the full aggregate excess-of-loss reinsurance coverage amount. In the same scenario, the related embedded derivative would no longer have value.

(1)Assets held by the Eagle Re Issuers are required to be invested in U.S. government money market funds, cash or U.S. Treasury securities. Liabilities of the Eagle Re Issuers consist of their mortgage insurance-linked notes as described above. Assets and liabilities are equal to each other for each of the Eagle Re Issuers.

Other Collateral

Although we use reinsurance as one of our risk management tools, reinsurance does not relieve us of our obligations to our policyholders. In the event the reinsurers are unable to meet their obligations to us, our insurance subsidiaries would be liable for any defaulted amounts. However, consistent with the PMIERs reinsurer counterparty collateral requirements, Radian Guaranty’s reinsurers have established trusts to help secure our potential cash recoveries. In addition to the total VIE assets of the Eagle Re Issuers discussed above, the amount held in reinsurance trusts was $274 million as of December 31, 2023, compared to $175 million as of December 31, 2022.

In addition, primarily for the Single Premium QSR Program, Radian Guaranty holds amounts related to ceded premiums written to collateralize the reinsurers’ obligations, which is reported in reinsurance funds withheld on our consolidated balance sheets. Any loss recoveries and profit commissions paid to Radian Guaranty related to the Single Premium QSR Program are expected to be realized from this account.

Right-of-Use Assets

During 2021, in response to the COVID-19 pandemic and our transition to a hybrid work environment, we made the decision to exit, and to actively market for sublease, all office space in our former corporate headquarters in downtown Philadelphia. As part of this change, we entered into two new leases with reduced square footage, including our new corporate headquarters, effective September 2021, in Wayne, Pennsylvania and a Cherry Hill, New Jersey location.

As a result of this decision and our ongoing evaluation of all of our existing leases, future space needs and evolving sublease market conditions, we recognized impairments to our right-of-use assets of $5 million and $8 million for the years

ended December 31, 2023 and 2022, respectively. In addition, we recognized impairments to related property and equipment, including leasehold improvements, of $4 million and $5 million for the years ended December 31, 2023 and 2022, respectively. These impairments related primarily to our former corporate headquarters leases and reduced the carrying value of certain lease assets and the related property and equipment to their estimated fair values. The right-of-use asset fair values were estimated using an income approach based on forecasted future cash flows expected to be derived from the property based on projected sublease market rents, which could differ from actual results and require us to revise our estimates in future periods. Following these impairments, which were recorded within other operating expenses on our consolidated statements of operations, the aggregate carrying value of the right-of-use assets and leasehold improvements related to the former corporate headquarters leases was $6 million as of December 31, 2023.

Current and Deferred Taxes

As of both December 31, 2023 and 2022, our current federal income tax liability was $21 million, which primarily relates to applying the standards of accounting for uncertainty in income taxes, and is included as a component of other liabilities in our consolidated balance sheets.

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance, and this assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods. Certain entities within our consolidated group have generated net deferred tax assets relating primarily to state and local NOL carryforwards which, if unutilized, will expire during various future tax periods. We have determined that certain of these entities may continue to generate taxable losses on a separate company basis in the near term and may not be able to fully utilize certain of their state and local NOLs on their state and local tax returns. Therefore, we have concluded a valuation allowance is required with respect to deferred tax assets relating to these state and local NOLs and other state timing adjustments. As of December 31, 2023 and 2022, this valuation allowance was $63 million and $70 million, respectively.

In addition, as of December 31, 2023, we have generated deferred tax assets related to unrealized capital losses, and we consider it more likely than not that these assets will be realized. We will continue to monitor the level of these losses and our overall ability to realize the related deferred tax assets in the coming quarters.

As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, under Internal Revenue Code Section 832(e) for amounts required by state law or regulation to be set aside in statutory contingency reserves. The deduction is allowed only to the extent that, in conjunction with quarterly federal tax payment due dates, we purchase non-interest-bearing U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury in an amount equal to the tax benefit derived from deducting any portion of our statutory contingency reserves. As of December 31, 2023 and 2022, we held $750 million and $596 million, respectively, of these bonds, which are included as prepaid federal income

taxes in our consolidated balance sheets. The corresponding deduction of our statutory contingency reserves resulted in the recognition of a net deferred tax liability. See Note 16 for additional information about our U.S. Mortgage Guaranty Tax and Loss Bonds.

On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022 (“IRA”) which, among other things, implemented a 15% minimum tax on book income of certain large corporations, a 1% excise tax on net stock repurchases that occur after December 31, 2022, and several tax incentives to promote clean energy. The new minimum tax, 1% excise tax and other income tax provisions of the IRA did not have a material impact on the Company.

Unrecognized Tax Benefits

As of December 31, 2023, we have $4 million of net unrecognized tax benefits, including $3 million of interest and penalties, that would affect the effective tax rate if recognized. Our policy for the recognition of interest and penalties associated with uncertain tax positions is to record such items as a component of our income tax provision, of which $776 thousand of expense and $182 thousand of benefit were recorded for the years ended December 31, 2023 and 2022, respectively.

A reconciliation of the beginning and ending gross unrecognized tax benefits is as follows.

Reconciliation of gross unrecognized tax benefits
	Years Ended December 31,
(In thousands)	2023		2022
Balance at beginning of period	$	20,810	$	19,888
Tax positions related to the current year:

Lapses of applicable statute of limitation	(20,623)		(18,518)
Balance at end of period	$	19,931	$	20,810

Our gross unrecognized tax benefits decreased by $879 thousand from December 31, 2022, to December 31, 2023, primarily as a result of reductions related to lapses of the statute of limitations. Although unrecognized tax benefits decreased due to statute expirations, certain amounts for premium income recognition continued to impact subsequent years, resulting in a corresponding increase in unrecognized tax benefits related to premium income recognition. Over the next 12 months, our unrecognized tax benefits may decrease by approximately $297 thousand due to the expiration of the applicable statute of limitations relating to the 2020 tax year. The statute of limitations related to our federal consolidated income tax return remains open for tax years 2020-2023. Additionally, among the entities within our consolidated group, various tax years remain open to potential examination by state and local taxing authorities.

(1)Related to ceded losses recoverable, if any, on reinsurance transactions. See Note 8 for additional information.

(2)Related to underlying defaulted loans with a most recent default notice dated in the year indicated. For example, if a loan had defaulted in a prior year, but then subsequently cured and later re-defaulted in the current year, that default would be considered a current year default.

Reserve Activity

Incurred Losses

Total incurred losses are driven by: (i) case reserves established for new default notices, which are primarily impacted by both the number of new primary default notices received in the period and our related gross Default to Claim Rate assumption applied to those new defaults and (ii) reserve developments on prior period defaults, which are primarily impacted by changes to our prior Default to Claim Rate assumptions.

New primary default notices totaled 44,007 for the year ended December 31, 2023, compared to 37,738 for the year ended December 31, 2022, and 37,470 for the year ended December 31, 2021.

Our gross Default to Claim Rate assumption applied to new defaults was 8.0% for all periods presented, as we continue to closely monitor the trends in Cures and claims paid for our default inventory, while also weighing the risks and uncertainties associated with the current economic environment.

Our provision for losses during 2023, 2022 and 2021 was positively impacted by favorable reserve development on prior year defaults, primarily as a result of more favorable trends in Cures than originally estimated. These Cures have been due primarily to favorable outcomes resulting from mortgage forbearance programs implemented in response to the COVID-19 pandemic as well as positive trends in home price appreciation, which has also contributed to a higher rate of claims that result in no ultimate loss and that are withdrawn by servicers as a result. These favorable observed trends resulted in reductions in our Default to Claim Rate and other reserve adjustments for prior year default notices. As the remaining number of defaults has continued to decline, the magnitude of the impact to our provision for losses from reserve development on prior year defaults has declined as well.

Default to Claim Rate

Our Default to Claim Rate estimates on defaulted loans are mainly developed based on the Stage of Default and Time in Default of the underlying defaulted loans grouped according to the period in which the default occurred, as measured by the progress toward foreclosure sale and the number of months in default. During 2023 and 2022, the ongoing favorable trend in Cures resulting from the positive effects of mortgage forbearance programs and the positive trends in home price appreciation contributed to reductions in our claims paid, including as a result of an increase in the number of claims that are withdrawn by servicers with no ultimate loss, which in turn led to a reduction in our Default to Claim Rates and other reserve assumptions.

The following table shows our gross Default to Claim Rates on our primary portfolio based on the Time in Default and as of the dates indicated.

Default to Claim Rates
	December 31,

Default to Claim Rate on:
New defaults	8.0	%	8.0	%	8.0	%
Defaults not in Foreclosure Stage

Time in Default: 2 - 5 years	55.0	%	65.0	%	75.0	%
Time in Default: > 5 years	60.0	%	70.0	%	80.0	%
Foreclosure Stage Defaults	65.0	%	75.0	%	85.0	%

(1)Represents the weighted average Default to Claim Rate for all defaults not in foreclosure stage that have been in default for up to two years, including new defaults. The estimated Default to Claim Rates applied to defaults within this population vary by Time in Default, and range from the Default to Claim Rates on new defaults shown above, up to 50.0%, 55.0% and 80.1% for more aged defaults in this category as of December 31, 2023, 2022 and 2021, respectively.

Our estimate of expected Rescissions, Claim Denials and claim withdrawals (net of expected Reinstatements) is then applied to our estimated gross Default to Claim Rates and is generally based on our recent experience. Consideration is also given to differences in characteristics between those rescinded policies, denied claims and claim withdrawals and the loans remaining in our defaulted inventory.

Claims Paid

Total claims paid decreased in 2023 compared to 2022. The decrease in claims paid is primarily attributable to a reduction in commutations and settlements.

Concentration of Risk

As of December 31, 2023, Texas accounted for 10% of our mortgage insurance business measured by primary RIF, as compared to no states at or above this measure as of December 31, 2022. Texas accounted for 13% and 12% of our direct NIW for the years ended December 31, 2023 and 2022, respectively, while California accounted for 11% for the year ended December 31, 2021.

Additional Disclosures

The following tables provide information as of and for the periods indicated about: (i) incurred losses, net of reinsurance; (ii) the total of IBNR liabilities plus expected development on reported claims, included within the net incurred loss amounts; (iii) the cumulative number of reported defaults; and (iv) cumulative paid claims, net of reinsurance. The default year represents the period that a new default notice is first reported to us by loan servicers, related to borrowers who missed two monthly payments.

(2)Represents total number of new primary default notices received in each calendar year as compiled monthly based on reports received from loan servicers. As reflected in our Default to Claim Rate assumptions, a significant portion of reported defaults generally do not result in a claim. In certain instances, a defaulted loan may cure, and then re-default in a later period. Consistent with our reserving practice, each new event of default is treated as a unique occurrence and therefore certain loans that cure and re-default may be included as a reported default in multiple periods.

Covenants in Senior Notes. The indentures governing the Senior Notes due 2024, 2025 and 2027 contain covenants customary for securities of this nature, including covenants related to the payments of the notes, periodic reporting and certificates to be issued and covenants related to amendments to the indentures. Additionally, the indentures include covenants restricting us from encumbering the capital stock of a designated subsidiary (as defined in the indenture for the

143

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

notes) or disposing of any capital stock of any designated subsidiary unless either all of the stock is disposed of or we retain more than 80% of the stock. We were in compliance with all covenants as of December 31, 2023.

FHLB Advances

Radian Guaranty is a member of the FHLB. As a member, it may borrow from the FHLB, subject to certain conditions, which include the need to post collateral and the requirement to maintain a minimum investment in FHLB stock, in part depending on the level of its outstanding FHLB advances.

Interest on the FHLB advances is primarily fixed-rate and is payable quarterly, or at maturity if the term of the advance is less than 90 days. Principal is due at maturity. For obligations with maturities greater than or equal to 90 days, we may prepay the debt at any time, subject to paying a prepayment fee.

The principal balance of the FHLB advances is required to be collateralized by eligible assets with a fair value that must be maintained generally within a minimum range of 103% to 114% of the amount borrowed, depending on the type of assets pledged. Our fixed-maturities available for sale and trading securities include securities totaling $101 million and $164 million at December 31, 2023 and 2022, respectively, which serve as collateral for our FHLB advances to satisfy this requirement.

Mortgage Loan Financing Facilities

In 2022, Radian Mortgage Capital entered into the BMO Master Repurchase Agreement and the Goldman Sachs Master Repurchase Agreement to finance the acquisition of residential mortgage loans and related mortgage loan assets. The Goldman Sachs Master Repurchase Agreement is an uncommitted mortgage loan repurchase facility that initially had a maximum borrowing amount of $300 million and was amended in July 2023 to reduce the maximum borrowing amount to $100 million. The BMO Master Repurchase Agreement, which is also uncommitted, initially had a maximum borrowing amount of $300 million and was amended in April 2023 to reduce the maximum borrowing amount to $150 million. The Goldman Sachs Master Repurchase Agreement and the BMO Master Repurchase Agreement are currently scheduled to expire on September 14, 2024, and September 25, 2024, respectively.

In January 2024, Radian Mortgage Capital entered into a master repurchase agreement with Flagstar Bank, N.A. (“Flagstar”). This agreement is an uncommitted mortgage loan repurchase facility with a maximum borrowing amount of $150 million pursuant to which Radian Mortgage Capital may from time to time sell to Flagstar, and later repurchase, certain residential mortgage loan assets. The Flagstar Master Repurchase Agreement is scheduled to expire on January 27, 2025.

The Master Repurchase Agreements are uncommitted, and Goldman Sachs Bank USA (“Goldman Sachs”), Bank of Montreal, a Canadian chartered bank acting through its Chicago branch (“BMO”) and Flagstar are under no obligation to fund the purchase of any residential mortgage loan assets under their respective agreements. In the event Goldman Sachs, BMO or Flagstar advances funds to purchase residential mortgage loan assets, the amount of such advances generally will be calculated as a percentage of the unpaid principal balance or market value of the residential mortgage loan assets, depending on the credit characteristics of the loans being purchased.

As of December 31, 2023, there were $21 million and $3 million of outstanding borrowings under the BMO Master Repurchase Agreement and the Goldman Sachs Master Repurchase Agreement, respectively. Of our mortgage loans held for sale, $31 million and $2 million at December 31, 2023 and 2022, respectively, served as collateral for the Master Repurchase Agreements to support the funds advanced.

The borrowings under the Master Repurchase Agreements bear a variable interest rate based on one-month SOFR or compounded SOFR, depending on the agreement, plus an applicable margin, with interest payable monthly. Principal is due upon the earliest of the sale or disposition of the related mortgage loans, the occurrence of certain default or acceleration events or at the termination date of the applicable Master Repurchase Agreement.

The Master Repurchase Agreements contain provisions that provide Goldman Sachs, BMO and Flagstar, respectively, with certain rights in the event of a decline in the market value of the purchased residential mortgage loan assets. Under these provisions, Radian Liberty Funding or Radian Mortgage Capital, as applicable, may be required to transfer cash or additional eligible residential mortgage loan assets with an aggregate market value that is equal to the difference between the value of the residential mortgage loan assets then subject to the applicable Master Repurchase Agreement and a minimum threshold amount.

Radian Group has entered into the Parent Guarantees to guaranty the obligations of certain of its subsidiaries in connection with the Master Repurchase Agreements described above.

Pursuant to the Parent Guarantees, Radian Group is subject to negative and affirmative covenants customary for this type of financing transaction, including, among others, limitations on the incurrence of debt and restrictions on certain transactions with affiliates, payments and investments and various financial covenants that the Company must remain in compliance with, including those related to: (i) the total adjusted capital of the Company’s primary mortgage insurance subsidiary, currently Radian Guaranty; (ii) the Company’s minimum consolidated net worth; and (iii) the Company’s maximum Debt-to-Total Capitalization Ratio (as defined in the Parent Guarantees). The covenants and financial covenants in the Parent

144

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

Guarantees are generally consistent with the comparable covenants in the Company’s revolving credit facility, including with respect to the payment of dividends on shares of its common stock which are permitted under the revolving credit facility and the Master Repurchase Agreements so long as no default or event of default exists and the Company is in pro forma compliance with the applicable financial covenants on the date a dividend is declared. As of December 31, 2023, we are in compliance with all of the debt covenants under our mortgage loan financing facilities.

Revolving Credit Facility

Radian Group has in place a $275 million unsecured revolving credit facility with a syndicate of bank lenders. The revolving credit facility matures in December 2026, although under certain conditions Radian Group may need to offer to repay any outstanding amounts and terminate lender commitments earlier than the maturity date. Terms of the credit facility include an accordion feature that allows Radian Group, at its option, to increase the total borrowing capacity during the term of the agreement, subject to our obtaining the necessary increased commitments from lenders (which may include then existing or other lenders), up to a total of $400 million.

Subject to certain limitations, borrowings under the credit facility may be used for working capital and general corporate purposes, including capital contributions to Radian Group’s insurance and other subsidiaries as well as growth initiatives. The credit facility contains customary representations, warranties, covenants, terms and conditions. Our ability to borrow under the credit facility is conditioned on the satisfaction of certain financial and other covenants, including covenants related to minimum net worth and statutory surplus, a maximum debt-to-capitalization level, limits on certain types of indebtedness and liens, and Radian Guaranty’s eligibility as a private mortgage insurer with the GSEs. At December 31, 2023, Radian Group was in compliance with all the covenants and there were no amounts outstanding under this revolving credit facility.

13. Commitments and Contingencies

Legal Proceedings

We are routinely involved in a number of legal actions and proceedings, including reviews, audits, inquiries, information-gathering requests and investigations by various regulatory entities, as well as litigation and other disputes arising in the ordinary course of our business.

We also are periodically subject to reviews and audits, as well as inquiries, information-gathering requests and investigations, by various regulatory entities. In connection with these matters, from time to time we receive requests and subpoenas seeking information and documents related to aspects of our business. Our Master Policies establish the timeline within which any suit or action arising from any right of an insured under the policy generally must be commenced. In general, any suit or action arising from any right of an insured under the policy must be commenced within two years after such right first arose for primary insurance and within three years for certain other policies, including certain Pool Mortgage Insurance policies. Although we believe that our Loss Mitigation Activities are justified under our policies, from time to time we face challenges from certain lender and servicer customers regarding our Loss Mitigation Activities. These challenges could result in additional arbitration or judicial proceedings and we may need to reassume the risk on, and increase loss reserves for, the associated policies or pay additional claims.

In the course of our regular review of pending legal actions and proceedings, we determine whether it is reasonably possible that a potential loss may have a material impact on our liquidity, results of operations or financial condition. If we determine such a loss is reasonably possible, we disclose information relating to such potential loss, including an estimate or range of loss or a statement that such an estimate cannot be made. On a quarterly basis, we review relevant information with respect to loss contingencies and update our accruals, disclosures and estimates of reasonably possible losses or range of losses based on such reviews. We are often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from other parties and investigation of factual allegations, rulings by the court on motions or appeals, analysis by experts and the progress of settlement negotiations. In addition, we generally make no disclosures for loss contingencies that are determined to be remote. For matters for which we disclose an estimated loss, the disclosed estimate reflects the reasonably possible loss or range of loss in excess of the amount accrued, if any.

Management believes, based on current knowledge and after consultation with counsel, that the outcome of currently pending or threatened actions will not have a material adverse effect on our consolidated financial condition or results of operations. The outcome of legal actions and proceedings is inherently uncertain, and it is possible that any one or more matters could have an adverse effect on our liquidity, financial condition or results of operations for any particular period. In accordance with applicable accounting standards and guidance, we establish accruals only when we determine both that it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. We accrue the amount that represents our best estimate of the probable loss; however, if we can only determine a range of estimated losses, we accrue an amount within the range that, in our judgment, reflects the most likely outcome, and if none of the estimates within the range is more likely, we accrue the minimum amount of the range.

145

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

Legal actions and proceedings could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief that could require significant expenditures or have other effects on our business in excess of amounts we have established as reserves for such matters. Loss estimates are inherently subjective, based on currently available information and are subject to management’s judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal and other proceedings, actual results may differ materially from any amounts that have been accrued.

Lease Liability

Our lease liability represents the present value of future lease payments over the lease term. Our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate, on a collateralized basis, to discount the lease payments based on information available at lease commencement. Our leases expire periodically through August 2032 and contain provisions for scheduled periodic rent increases. We estimate the incremental borrowing rate based on the yields of Radian Group corporate bonds, as adjusted to reflect a collateralized borrowing rate, resulting in discount rates ranging from 4.8% to 7.5%. While the majority of our lease population expires within one year of one of Radian Group’s corporate bonds, our more significant leases do not. For those leases, we adjust the corporate bond rate for both U.S. Department of the Treasury rate yields, and a corporate spread adjustment determined from recent market data.

The following tables provide additional information related to our leases, including: (i) the components of our total lease cost; (ii) the cash flows arising from our lease transactions; (iii) supplemental balance sheet information; (iv) the weighted-average remaining lease term; (v) the weighted-average discount rate used for our leases; and (vi) the remaining maturities of our lease liabilities, as of and for the periods indicated.

We entered into a sublease agreement in January 2022 for a portion of the office space in our former corporate headquarters in Philadelphia and are actively marketing additional space in that location for sublease. Upon entering a sublease agreement, we generally do not anticipate being relieved of our primary obligation under the original lease and will act as a lessor recognizing any sublease income on a straight-line basis over the remaining lease term as an offset to other operating expenses.

Other

We provide contract underwriting to our mortgage insurance customers, pursuant to which we offer limited indemnification remedies. In 2023 and 2022, our provision for contract underwriting expenses and our payments for losses related to contract underwriting remedies were de minimis. We monitor this risk and negotiate our underwriting fee structure and recourse agreements on a client-by-client basis. We also routinely audit the performance of our contract underwriters.

Share Repurchase Activity

From time to time, Radian Group’s board of directors approves share repurchase programs authorizing the Company to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Radian generally operates its share repurchase programs pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which provides for share repurchases at predetermined price targets and permits the Company to purchase shares when it may otherwise be precluded from doing so.

In January 2023, Radian Group’s board of directors approved a share repurchase program authorizing the Company to spend up to $300 million, excluding commissions, to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Radian has implemented a trading plan under Rule 10b5-1 of the Exchange Act. The authorization will expire in January 2025. During the year ended December 31, 2023, the Company purchased 5.3 million shares at an average price of $25.32 per share, including commissions. As of December 31, 2023, purchase authority of up to $167 million remained available under this share repurchase program.

The Inflation Reduction Act of 2022 imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. All dollar amounts presented in this report related to our share repurchases and our share repurchase authorizations exclude such excise taxes, to the extent applicable, unless otherwise indicated. See Note 10 for additional information on this excise tax.

Other Purchases

We may purchase shares on the open market to settle stock options exercised by employees. In addition, upon the vesting of certain RSUs under our equity compensation plans, we may withhold from such vested awards shares of our common stock to satisfy the tax liability of the award recipients.

16. Statutory Information

Radian Group serves as the holding company for our insurance subsidiaries, through which we conduct our mortgage insurance and title insurance businesses. These insurance subsidiaries are subject to comprehensive, detailed regulation by the insurance departments in the various states where our insurance subsidiaries are domiciled or licensed to transact business. Insurance laws vary from state to state, but generally grant broad supervisory powers to state agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including the power to revoke or restrict an insurance company’s ability to write new business.

All of our mortgage insurance subsidiaries are domiciled in Pennsylvania. We currently write new mortgage insurance business using only one principal subsidiary, Radian Guaranty. Radian Guaranty is authorized as a monoline insurer to write mortgage guaranty insurance (or in states where there is no specific authorization for mortgage guaranty insurance, the applicable line of insurance under which mortgage guaranty insurance is regulated) in all 50 states, the District of Columbia and Guam.

As part of our title services, we offer title insurance through Radian Title Insurance, which is domiciled in Ohio and licensed to issue title insurance policies in 41 states and the District of Columbia.

In addition to complying with state insurance regulations, in order to be eligible to insure loans purchased by the GSEs, mortgage insurers such as Radian Guaranty must meet the GSEs’ eligibility requirements, or PMIERs. The PMIERs are comprehensive, covering virtually all aspects of the business and operations of a private mortgage insurer, including internal

149

Table of Contents Glossary

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

risk management and quality controls, the relationship between the GSEs and the approved insurer, as well as the approved insurer’s financial condition. See “PMIERs” below for additional information.

The PMIERs and state insurance regulations include various capital requirements and dividend restrictions based on our insurance subsidiaries’ statutory financial position and results of operations, as described below. Our failure to maintain adequate levels of capital could lead to intervention by the various insurance regulatory authorities, which could materially and adversely affect our business, business prospects and financial condition.

Statutory Financial Statements

We prepare our statutory financial statements in accordance with the accounting practices required or permitted, if applicable, by the insurance departments of the respective states of domicile of our insurance subsidiaries. Required SAP are established by the NAIC, as well as state laws, regulations and general administrative rules. In addition, insurance departments have the right to permit other specific practices that may deviate from prescribed practices. As of December 31, 2023, we did not have any prescribed or permitted SAP that resulted in reported statutory surplus or risk-based capital being materially different from what would have been reported had NAIC statutory accounting practices been followed.

Reflecting the principal differences between SAP and GAAP, statutory financial statements typically do not include unrealized gains or losses on fixed-maturity securities, deferred policy acquisition costs, certain net deferred tax assets and certain other less readily marketable assets that are designated as non-admitted assets. In addition to these general differences, SAP also requires that mortgage insurance companies establish a special contingency reserve equal to 50% of premiums earned in each year, generally to be maintained for 10 years, to protect policyholders against loss during adverse economic cycles.

As a result of the requirement to establish and maintain this statutory liability, contingency reserves affect the ability of a mortgage insurer to pay dividends, as described below. With regulatory approval, a mortgage insurance company may make early withdrawals from this contingency reserve when incurred losses exceed 35% of net premiums in a calendar year. During 2023, Radian Guaranty released $21 million from its contingency reserves due to the expiration of the 10-year holding requirement for the remaining contingency reserves established during 2013. Radian Guaranty did not release any amounts from its contingency reserves in 2022. Based on the typical 10-year holding requirement, Radian Guaranty is scheduled to release contingency reserves to unassigned surplus in material amounts beginning in 2024. See “Statutory Dividend Restrictions” below for additional information.

As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, related to amounts required to be set aside in statutory contingency reserves to the extent we purchase U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury. Under SAP, this deduction reduces the tax provision reflected in the statutory financial statements, which in turn increases statutory net income and surplus as well as Available Assets under the PMIERs. As of December 31, 2023, Radian Guaranty held $750 million of these bonds, which have a 10-year original maturity but may generally be redeemed in any tax year prior to maturity.

Our insurance subsidiaries’ statutory net income (loss) for the periods indicated, and statutory policyholders’ surplus as of the dates indicated, were as follows.

Statutory Capital Requirements

Under state insurance regulations, Radian Guaranty is required to maintain minimum surplus levels and, in certain states, a maximum ratio of net RIF relative to statutory capital, or Risk-to-capital. The most common Statutory RBC Requirement is that a mortgage insurer’s Risk-to-capital may not exceed 25 to 1. In certain of the RBC States, a mortgage insurer must satisfy an MPP Requirement. Unless an RBC State grants a waiver or other form of relief, if a mortgage insurer, such as Radian Guaranty, is not in compliance with the Statutory RBC Requirement of that state, the mortgage insurer may be prohibited from writing new mortgage insurance business in that state.

The statutory capital requirements for the non-RBC States are de minimis (ranging from $1 million to $5 million); however, the insurance laws of these states generally grant broad supervisory powers to state agencies or officials to enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including the power to revoke or restrict an insurance company’s ability to write new business. Radian Guaranty’s domiciliary state, Pennsylvania, is not one of the RBC States.

Radian Guaranty was in compliance with all applicable Statutory RBC Requirements and MPP Requirements in each of the RBC States as of December 31, 2023. Radian Guaranty’s Risk-to-capital was 10.4:1 and 10.7:1 as of December 31, 2023 and 2022, respectively. For purposes of the Risk-to-capital requirements imposed by certain states, statutory capital is defined as the sum of statutory policyholders’ surplus and statutory contingency reserves. Our other mortgage insurance and title insurance subsidiaries were also in compliance with all statutory and counterparty capital requirements as of December 31, 2023 and 2022.

During the past 10 years, the NAIC has been considering changes to the Model Act and has been reviewing the minimum capital and surplus requirements for mortgage insurers to develop a new capital standard for mortgage guaranty insurers and to “strengthen and modernize” the Mortgage Guaranty Insurance Model Act. In 2021, the NAIC developed a new, legally non-binding capital monitoring framework that regulators could use as an alternative for assessing the capital adequacy of a mortgage insurer and added a new mortgage guaranty supplemental filing for companies to annually report related information. This monitoring framework, which is separate from the Model Act, is intended to be reactive to, among other things, changes in the economic and housing environment, including changes in home prices and incomes. In August 2023, the NAIC adopted amendments that revise the Model Act, including with respect to capital and reserve requirements, reinsurance, underwriting practices, quality assurance, and policy form and rate filings. The requirements with respect to minimum capital and surplus requirements for mortgage insurers were not materially changed in the Model Act, as amended. The potential impact on the Company is not expected to be material and will depend on which states, if any, ultimately adopt the amended Model Act.

PMIERs

The PMIERs financial requirements require that a mortgage insurer’s Available Assets meet or exceed its Minimum Required Assets. At December 31, 2023, Radian Guaranty is an approved mortgage insurer under the PMIERs and is in compliance with the current PMIERs financial requirements.

The GSEs may amend the PMIERs at any time, and they have broad discretion to interpret the requirements; any amendments or changes in interpretation could impact the calculation of Radian Guaranty’s Available Assets and/or Minimum Required Assets. In addition, the GSEs have a broad range of consent rights under the PMIERs and require private mortgage insurers to obtain the prior consent of the GSEs before taking certain actions. If Radian Guaranty is unable to satisfy the requirements set forth in the PMIERs, the GSEs could restrict it from conducting certain types of business with them or take actions that may include not purchasing loans insured by Radian Guaranty.

Statutory Dividend Restrictions

As of December 31, 2023, the amount of restricted net assets held by our consolidated insurance subsidiaries (which represents our equity investment in those insurance subsidiaries) totaled $4.6 billion of our consolidated net assets. Despite holding assets above the minimum statutory capital thresholds and PMIERs financial requirements, the ability of Radian’s mortgage insurance subsidiaries to pay dividends on their common stock has been restricted by certain provisions of the insurance laws of Pennsylvania, their state of domicile.

Under Pennsylvania’s insurance laws, ordinary dividends and distributions may only be paid out of an insurer’s positive unassigned surplus unless the Pennsylvania Insurance Department approves the payment of extraordinary dividends or other distributions from another source. While all proposed dividends and distributions to stockholders must be filed with the Pennsylvania Insurance Department prior to payment, if a Pennsylvania domiciled insurer has positive unassigned surplus, such insurer can pay dividends or other distributions during any 12-month period in an aggregate amount less than or equal to the greater of: (i) 10% of the preceding year-end statutory policyholders’ surplus or (ii) the preceding year’s statutory net income, in each case without the prior approval of the Pennsylvania Insurance Department.

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

Aided by the positive impacts of the merger with Radian Reinsurance in December 2022, Radian Guaranty had positive unassigned surplus of $258 million as of December 31, 2022, and continued to maintain positive unassigned surplus throughout 2023. As a result, beginning with the first quarter of 2023, Radian Guaranty had the ability to pay ordinary dividends, and paid total ordinary dividends of $400 million in cash and marketable securities in 2023. As of December 31, 2023, Radian Guaranty had positive unassigned surplus of $120 million. Subsequent to year end, in February 2024, Radian Guaranty paid an ordinary dividend of $100 million in cash and marketable securities to Radian Group.

As of December 31, 2023 and 2022, Radian Guaranty had contingency reserves of $5.0 billion and $4.4 billion, respectively. As discussed above, Radian Guaranty is scheduled to release contingency reserves to unassigned surplus in material amounts beginning in 2024, which should enhance Radian Guaranty’s ability to maintain a positive unassigned surplus position and to continue to pay ordinary dividends to Radian Group in future periods.

The surplus additions (distributions) between Radian Group and Radian Guaranty and our other insurance subsidiaries for the years ended December 31, 2023, 2022 and 2021, were as follows.

(1)For 2023, consists of $400 million of ordinary dividends paid to Radian Group. For 2022, consists of $782 million in returns of capital and a $100 million repayment of a 0.0% interest intercompany surplus note originally due December 31, 2027.

(2)These distributions were from Radian Reinsurance prior to its merger with Radian Guaranty.

17. Share-Based Compensation and Other Benefit Programs

Our most recent Equity Plan is The Radian Group 2021 Equity Plan (the “2021 Equity Plan”), which was approved by our stockholders and applies to awards granted on or after May 12, 2021, the effective date of the plan (the “Effective Date”). In addition to the 2021 Equity Plan, we also have granted awards that remain outstanding under prior plans approved by our stockholders and adopted in each of 1995, 2008, 2014 and 2017 (collectively, the “Prior Equity Plans” and, together with the 2021 Equity Plan, the “Equity Plans”).

The 2021 Equity Plan authorizes the issuance of up to 8.3 million new shares of our common stock, plus: (i) any shares of our common stock that remained available for awards under the plan adopted in 2017 as of the Effective Date and (ii) any shares of our common stock subject to outstanding awards under the Prior Equity Plans as of the Effective Date that are payable in shares and that terminate, expire, or are canceled without having been exercised, vested, or settled in full (as applicable) on or after the Effective Date, subject to certain adjustments set forth in the 2021 Equity Plan (“Prior Plans Shares”). There were 5.3 million shares available for grant under the 2021 Equity Plan, including Prior Plans Shares, as of December 31, 2023.

Outstanding awards granted under the Equity Plans include both performance-based and time-based RSUs, non-qualified stock options and phantom stock. The maximum contractual term for stock options and similar instruments under the Equity Plans is 10 years. To date, all awards granted under the 2021 Equity Plan have been either performance-based or time-based RSUs.

Awards under our plans generally vest over performance or service periods ranging from one to three years, although they may vest earlier under certain circumstances, including in the event of a grantee’s death or disability or, if certain conditions are met, upon retirement, termination or a change of control.

The following table summarizes the compensation cost recognized and additional information regarding all share-based awards for the years indicated.

Share-based compensation expense, net	$	31,695	$	30,537	$	21,195

(1)Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. For purposes of calculating compensation cost recognized for retirement eligible grantees, we consider the service condition to be met (and recognize the full compensation costs) as of the date when a grantee becomes retirement eligible.

As of December 31, 2023, unrecognized compensation expense for all of our outstanding share-based awards was $28.6 million. Absent a change of control under the Equity Plans, this expense is expected to be recognized over a weighted-average period of approximately 1.9 years. The ultimate unrecognized expense associated with our outstanding awards could differ, depending upon whether or not the performance and service conditions are met.

RSUs

Information with regard to RSUs to be settled in stock for the periods indicated is as follows.

Rollforward of RSUs
	Performance-Based			Time-Vested
	Number of Shares	Weighted-Average Grant Date Fair Value		Number of Shares	Weighted-Average Grant Date Fair Value
Outstanding, December 31, 2022 (1)	2,362,401	$	17.59	1,891,800	$	16.16
Granted (2)	911,550	23.05		551,093	25.13

Outstanding, December 31, 2023 (1)	2,970,874	$	18.28	1,786,615	$	18.16

(1)Outstanding RSUs represent shares that have not yet been issued because not all conditions necessary to earn the right to benefit from the instruments have been satisfied. For performance-based awards, the final number of RSUs distributed depends on: (i) the cumulative growth in Radian’s book value per share adjusted for certain defined items over the respective three-year performance period and for the performance-based RSUs granted in 2023 also include a modifier based on a comparison of our total shareholder return to the total shareholder return of certain of our peers and (ii) with the exception of certain retirement-eligible employees, continued service through the vesting date, which could result in changes in the number of vested RSUs.

(2)For performance-based RSUs, amount represents the number of target shares at grant date.

(3)For performance-based RSUs, amount represents the difference between the number of shares vested at settlement, which can range from 0 to 200% of target depending on results over the applicable performance periods, and the number of target shares at the grant date.

(4)Represents amounts vested during the year, including the impact of performance adjustments for performance-based awards.

The weighted-average grant date fair value of performance-based RSUs granted during 2022 and 2021 was $20.09 and $20.39, respectively. The weighted-average grant date fair value of time-vested RSUs granted during 2022 and 2021 was $20.61 and $21.71, respectively.

The fair value as of the respective vesting dates of performance-based RSUs vested during 2023, 2022 and 2021 was $27 million, $17 million and $19 million, respectively. The fair value as of the respective vesting dates of time-vested RSUs vested during 2023, 2022 and 2021 was $16 million, $11 million and $18 million, respectively.

Dividend equivalents are accrued on all awards when dividends are declared on the Company’s common stock and will generally be paid in cash when the awards are settled.

Performance-Based RSUs. For awards granted in 2023, 2022 and 2021, the vesting of the performance-based RSUs is generally over a three-year performance period and will be based primarily upon the cumulative growth in Radian’s book value per share, adjusted for certain defined items, which in 2023 includes our total shareholder return relative to certain peers. The

153

Radian Group Inc. and Subsidiaries Notes to Consolidated Financial Statements

payout at the end of the three-year performance period generally ranges from 0% to a maximum payout of 200% of the award’s target number of RSUs granted. Performance-based RSUs granted to executive officers are subject to a one-year post-vesting holding period.

The grant date fair value of the performance-based RSUs that are based on the cumulative growth in Radian’s book value per share, as further described above, is calculated based on the stock price as of the grant date, discounted for executive officers to account for the one-year post-vesting holding period. In addition, we adjust the expense recognized on these performance condition awards over the service period to incorporate the probable outcome of achieving the performance measure. For awards that include a total shareholder return market condition in its criteria, we also incorporate a Monte Carlo valuation model at grant date based on multiple input variables, including expected volatilities, correlation coefficients and risk-free interest rates.

Time-Vested RSUs. With the exception of certain time-vested RSUs granted in 2023, 2022 and 2021 to non-employee directors, the time-vested RSU awards granted in 2023, 2022 and 2021 are scheduled to vest in: (i) pro rata installments on a common calendar date that is on or around each of the first three anniversaries of the grant date or (ii) generally at the end of three years. Certain time-vested RSU awards granted in 2023, 2022 and 2021 to non-employee directors generally are subject to one-year cliff vesting; however, awards granted to non-employee directors prior to 2020 remain outstanding and the shares are not issued until the non-employee director retires or certain conditions related to a change in control are met, as described above.

Non-Qualified Stock Options

Upon the exercise of stock options, we generally issue shares from the authorized, unissued share reserves when the exercise price is less than the treasury stock repurchase price and from treasury stock when the exercise price is greater than the treasury stock repurchase price.

Generally, the stock option awards had a four-year vesting period, with 50% of the award vesting on or after the third anniversary of the grant date and the remaining 50% of the award vesting on or after the fourth anniversary of the grant date, provided the applicable stock price performance hurdle is met. There have been no stock options granted since 2016.

Employee Stock Purchase Plan

The ESPP is designed to allow eligible employees to purchase shares of our common stock at a discount of 15% off the lower of the fair market value of our common stock at the beginning or end of a six-month offering period (each period being the first and second six months in a calendar year).

Under this plan, we issued approximately 100 thousand shares to employees during each of the years ended December 31, 2023, 2022 and 2021. As of February 2024, approximately 1.4 million shares remain available for issuance under the ESPP.

Benefit Plans

The Radian Group Inc. Savings Incentive Plan (“Savings Plan”) covers substantially all of our full-time and our part-time employees. Participants can contribute up to 100% of their eligible earnings as pretax and/or after-tax (Roth IRA) contributions up to a maximum Internal Revenue Service annual limit, which was $22,500 for 2023. The Savings Plan also includes the catch-up contribution provision whereby participants who are or will be age 50 and above during the Savings Plan year may contribute an additional contribution. The maximum catch-up contribution for the Savings Plan in 2023 was $7,500. We match up to 100% of the first 6% of eligible compensation contributed in any given year. Our expense for matching funds for the years ended December 31, 2023, 2022 and 2021, was $8 million, $10 million and $8 million, respectively.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

We maintain disclosure controls and procedures designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of December 31, 2023, pursuant to Rule 15d-15(b) under the Exchange Act. Management necessarily applied its judgment in assessing the costs and benefits of such controls and procedures, which by their nature, can provide only reasonable assurance regarding management’s control objectives. Management does not expect that our disclosure controls and procedures will prevent or detect all errors and fraud. A control system, irrespective of how well it is designed and operated, can only provide reasonable assurance and cannot guarantee that it will succeed in its stated objectives.

Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2023, our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. Our internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that our receipts and expenditures are being made only in accordance with authorizations of our management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

155

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control over financial reporting, as of December 31, 2023, using the criteria described in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the updated internal control framework in Internal Control-Integrated Framework (2013), management concluded that our internal control over financial reporting was effective as of December 31, 2023. The effectiveness of our internal control over financial reporting as of December 31, 2023, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report appearing in Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There was no change in the internal control over financial reporting that occurred during the quarter ended December 31, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information

None of the directors or officers (as defined in Rule 16a-1(f) promulgated under the Exchange Act) of the Company adopted or terminated any Rule 10b5-1 trading arrangement or any non-Rule 10b5-1 trading arrangement (as such terms are defined in Item 408 of Regulation S-K) during the period covered by this Report.

Radian Group Inc.

Schedule II—Financial Information of Registrant
Supplemental Notes

Parent Company Only

Note A

The Radian Group Inc. (the “Parent Company,” “we” or “our”) financial statements represent the stand-alone financial statements of the Parent Company. These financial statements have been prepared on the same basis and using the same accounting policies as described in the consolidated financial statements included herein, except that the Parent Company uses the equity-method of accounting for its majority-owned subsidiaries. These financial statements should be read in conjunction with our consolidated financial statements and the accompanying notes thereto.

See Notes 12 and 14 of Notes to Consolidated Financial Statements for additional information on the Parent Company’s debt obligations and capital stock.

The Parent Company has entered into the following guarantees on behalf of our subsidiaries:

■Beginning in 2022, Radian Group entered into certain Parent Guarantees to support its mortgage conduit business. See Note 12 of Notes to Consolidated Financial Statements for additional information.

■To allow our mortgage insurance customers to comply with applicable securities regulations for issuers of ABS (including mortgage-backed securities), Radian Group has guaranteed two structured transactions for Radian Guaranty with $54 million of aggregate remaining credit exposure as of December 31, 2023.

■Radian Group and Radian Mortgage Assurance are parties to a guaranty agreement, which provides that Radian Group will make sufficient funds available to Radian Mortgage Assurance to ensure that Radian Mortgage Assurance has a minimum of $5 million of statutory policyholders’ surplus every calendar quarter. Radian Mortgage Assurance had $9 million of statutory policyholders’ surplus and no RIF exposure as of December 31, 2023.

As of December 31, 2023, Radian Group recorded a net deferred tax liability of $226 million. This balance includes liabilities related to certain of our subsidiaries, which have incurred federal NOLs that could not be carried-back and utilized on a separate company tax return basis. As a result, we are not currently obligated under our tax-sharing agreement to reimburse these subsidiaries for their separate company federal NOL carryforward. However, if in a future period one of these subsidiaries utilizes its share of federal NOL carryforwards on a separate entity basis, then Radian Group may be obligated to fund such subsidiary’s share of our consolidated tax liability to the Internal Revenue Service.

Note B

The Parent Company provides certain services to its subsidiaries. The Parent Company allocates to its subsidiaries expenses it incurs in the capacity of supporting those subsidiaries, including operating expenses, which are allocated based on the forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on certain subsidiaries, and interest expense, which is allocated based on relative capital. These expenses are presented net of allocations in the Condensed Statements of Operations. Substantially all operating expenses and interest expense have been allocated to the subsidiaries for 2023, 2022 and 2021.

Amounts allocated to the subsidiaries for expenses are based on actual cost, without any mark-up. The Parent Company considers these charges to be fair and reasonable. The subsidiaries generally reimburse the Parent Company for these costs in a timely manner, which has the impact of temporarily improving the cash flows of the Parent Company, if accrued expenses are reimbursed prior to actual payment.

The following table shows the components of our Parent Company expenses that have been allocated to our subsidiaries for the periods indicated.

Total allocated expenses
	Years Ended December 31,
(In thousands)	2023		2022		2021
Allocated operating expenses	$	163,858	$	163,000	$	147,386
Allocated interest expense	82,734		82,568		82,833
Total allocated expenses	$	246,592	$	245,568	$	230,219

174

Note C

During 2023 and 2022, certain non-insurance subsidiaries had not generated sufficient cash flow to reimburse the Parent Company for its share of its direct and allocated operating expenses, and therefore the Parent Company effectively contributed a total of $110 million and $82 million, respectively, to these subsidiaries to reflect the impairment of the intercompany receivables representing unreimbursed direct and allocated costs.

See Note 16 of Notes to Consolidated Financial Statements for additional information related to capital transactions between the Parent Company and its consolidated insurance subsidiaries, including $400 million in ordinary dividends paid during 2023 from Radian Guaranty to Radian Group.

Note D

As of December 31, 2023 and 2022, the Parent Company’s other assets related primarily to: (i) its participation in a securities lending program; (ii) intercompany receivables; and (iii) property and equipment. As of December 31, 2023 and 2022, the Parent Company’s other liabilities related primarily to: (i) accounts payable and accrued expenses and (ii) its participation in a securities lending program. See Note 6 of Notes to Consolidated Financial Statements for additional information on this program.

Incentive Compensation Recoupment Policy

Effective as of October 2, 2023

ARTICLE A.

Purpose and General Terms

Section A-1.    Purpose.

Radian Group Inc. has adopted this Incentive Compensation Recoupment Policy (this “Policy”) to implement a mandatory clawback policy in compliance with the applicable rules of the New York Stock Exchange, which is set forth in Article B of this Policy and to continue to maintain a discretionary clawback policy, which is set forth in Article C of this Policy.

Radian Group Inc. and its subsidiaries are collectively referred to as the “Company.” The term “Committee” refers to the Compensation and Human Capital Management Committee of the Board of Directors of the Company (the “Board”), or, in the absence of such committee, a majority of independent directors serving on the Board.

Any capitalized terms used, but not immediately defined, in this Policy have the meanings set forth in Section A-7.

Section A-2. Administration.

This Policy shall be administered in the sole discretion of the Committee. The Committee shall have the discretion to interpret the Policy and make all determinations with respect to this Policy, consistent with applicable law and this Policy. Without limiting the foregoing, Article B of this Policy shall be interpreted in a manner that is consistent with the requirements of the Applicable Rules, and compliance with Article B shall not be waived by the Committee, the Board or the Company in any respect. The Board may assume any or all powers and authority of the Committee with respect to administration of Article C, in which case references to the Committee shall be deemed to include the Board, as applicable.

Any interpretations and determinations made by the Committee shall be final and binding on all affected individuals.

Section A-3. Effective Date; Term.

This Policy is adopted as of November 15, 2023 with retroactive effectiveness as of October 2, 2023 (the “Effective Date”). Article B of this Policy applies to Incentive-Based Compensation that is Received by any Executive Officer on or after the Effective Date as described in Section B-2 below. As of the Effective Date, this Policy supersedes the Company’s Incentive Compensation Recoupment Policy then in effect (the “Prior Policy”) with respect to Covered Compensation granted on or after the Effective Date. The Prior Policy continues to apply with respect to Covered Compensation granted prior to the Effective Date.

Section A-4. Amendment.

The Committee may amend this Policy from time to time in its discretion, subject to any limitations under applicable law or listing standards, including, in the case of Article B, the Applicable Rules. Without limiting the foregoing, the Committee may amend this Policy as it deems necessary to reflect any amendment of the Applicable Rules or regulations or guidance issued under the Applicable Rules.

1

Section A-5.    No Substitution of Rights; Non-Exhaustive Rights.

Any right of recoupment under this Policy is in addition to, and not in lieu of, any other remedies or rights that may be available to the Company pursuant to (a) any of the Company’s equity plans, the Company’s annual bonus plans, any other incentive plans of the Company, or any successor plan to any of the foregoing, (b) the terms of any recoupment policy or provision in any employment agreement, compensation agreement or arrangement, or other agreement, or (c) any other legal remedies available to the Company under applicable law.

In addition to recovery of compensation as provided for in this Policy, the Company may take any and all other actions as it deems necessary, appropriate and in the Company’s best interest in connection with the Committee determining that this Policy should apply, including termination of the employment of, or initiating legal action against, a Covered Person, and nothing in this Policy limits the Company’s rights to take any such appropriate actions.

Section A-6. Governing Law.

This Policy and all determinations made and actions taken pursuant hereto, to the extent not otherwise governed by mandatory provisions of the Applicable Rules, shall be governed by and construed in accordance with the laws of the State of Delaware without regard to choice of law principles. If any provision of this Policy shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of this Policy, but this Policy shall be construed and enforced as if the illegal or invalid provision had never been included in this Policy.

Section A-7. Defined Terms.

The following capitalized terms used in this Policy have the following meanings, and where applicable, such terms will be interpreted to comply with the Applicable Rules:

(a)“Applicable Rules” means Section 10D of the Exchange Act and Rule 10D-1 promulgated thereunder and Section 303A.14 of the Listed Company Manual of the New York Stock Exchange LLC.

(b)“Clawback Compensation” means, for the purposes of Article B, Incentive-Based Compensation and, for the purposes of Article C, Covered Compensation, in each case as determined to be subject to repayment pursuant to this Policy.

(c)“Covered Compensation”, which is the compensation subject to Article C, means the following incentive compensation granted to a Covered Person: (i) Incentive-Based Compensation as defined in Section A-7(i) below; (ii) any other cash or equity incentive compensation that is based on the achievement of an objectively quantifiable performance measure or goal; and (iii) any proceeds or earnings received in respect of (i) or (ii). For the avoidance of doubt, the foregoing includes any compensation that is paid, earned, vested, deferred or paid or payable as a component of severance or termination compensation.

2

(d)“Covered Event,” which relates to Article C, means the following:

(i)for an Executive Officer, a Restatement or Overstatement has occurred, or

(ii)for a Covered Person other than an Executive Officer, an Overstatement or a Restatement has occurred and the Committee determines that a Covered Person engaged in fraud or other misconduct that directly or indirectly resulted in the Overstatement or Restatement, as applicable.

(e)“Covered Person,” which relates to Article C, means (i) each Executive Officer and (ii) any other officer of the Company who engaged in fraud or other misconduct that directly or indirectly resulted in a Restatement or Overstatement as determined by the Committee.

(i)“Incentive-Based Compensation” means any compensation that is granted, earned, or vested, based wholly or in part upon the attainment of a Financial Reporting Measure. Incentive-Based Compensation does not include, among other forms of compensation, equity awards that vest exclusively upon completion of a specified employment period, without any performance condition, and bonus awards that are discretionary or based on subjective goals or goals unrelated to Financial Reporting Measures.

(j)“Overstatement” means the level of achievement of an objectively quantifiable performance measure or goal was materially overstated other than as a result of a change in accounting principles.

(k)“Received” – Incentive-Based Compensation is deemed “Received” for the purposes of this Policy in the Company’s fiscal period during which the Financial Reporting Measure applicable to the Incentive-Based Compensation award is attained, even if the payment or grant of the Incentive- Based Compensation occurs after the end of that period.

(l)“Recovery Period” means: (i) for the purposes of Article B, the three completed fiscal years immediately preceding the date on which the Company is required to prepare a Restatement, which

3

(ii) that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period.

ARTICLE B.

Dodd-Frank Recoupment Policy for

Executive Officers

Section B-1. Recovery on a Restatement.

In the event that the Company is required to prepare a Restatement, the Company shall reasonably promptly recover from an Executive Officer the amount of any erroneously awarded Incentive-Based Compensation that is Received by such Executive Officer during the Recovery Period. The amount of erroneously Received Incentive-Based Compensation will be the excess of the Incentive-Based Compensation Received by the Executive Officer (whether in cash or shares) based on the erroneous data in the original financial statements over the Incentive-Based Compensation (whether in cash or in shares) that would have been Received by the Executive Officer had such Incentive-Based Compensation been based on the restated results, without respect to any tax liabilities incurred or paid by the Executive Officer.

Recovery of any erroneously awarded compensation under this Article B is not dependent on fraud or misconduct by any Executive Officer in connection with a Restatement.

Without limiting the foregoing, for Incentive-Based Compensation based on the Company’s stock price or total shareholder return, where the amount of erroneously awarded compensation is not subject to mathematical recalculation directly from the information in the Restatement, (a) the amount shall be based on the Company’s reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Incentive-Based Compensation was Received and (b) the Company shall maintain documentation of the determination of that reasonable estimate and provide such estimate to the NYSE as required by the Applicable Rules.

4

Section B-2.    Covered Executive Officers and Covered Incentive-Based Compensation.

This Article B covers all persons who are Executive Officers at any time during the Recovery Period for which Incentive-Based Compensation is Received or during the performance period applicable to such Incentive-Based Compensation. Incentive-Based Compensation shall not be recovered under this Article B to the extent Received by any person before the date the person served as an Executive Officer. Subsequent changes in an Executive Officer’s employment status, including retirement or termination of employment, do not affect the Company’s right to recover Incentive-Based Compensation pursuant to this Article B.

Article B of this Policy shall apply to Incentive-Based Compensation that is Received by any Executive Officer on or after the Effective Date and that results from attainment of a Financial Reporting Measure based on or derived from financial information for any fiscal period ending on or after the Effective Date. For the avoidance of doubt, this will include Incentive-Based Compensation that may have been approved, awarded, or granted to an Executive Officer on or before the Effective Date if such Incentive-Based Compensation is Received on or after the Effective Date.

Section B-3. Limited Exceptions to Methods of Recovery set forth in Article D.

The Committee shall determine, in its sole discretion, the method of recovering any Incentive-Based Compensation Received pursuant to this Article B, consistent with applicable law and including the methods of recovery described in Article D.

No recovery shall be required if any of the following conditions are met and the Committee determines that, on such basis, recovery would be impracticable:

(a)the direct expense paid to a third party to assist in enforcing this Article B would exceed the amount to be recovered; provided that prior to making a determination that it would be impracticable to recover any Incentive-Based Compensation based on the expense of enforcement, the Company shall (i) have made a reasonable attempt to recover the Incentive-Based Compensation, (ii) have documented such reasonable attempts to recover, and (iii) provide the documentation to the NYSE;

(b)recovery would violate home country law where that law was adopted prior to November 28, 2022; provided that, prior to making a determination that it would be impracticable to recover any Incentive-Based Compensation based on a violation of home country law, the Company shall

(i) have obtained an opinion of home country counsel, acceptable to the NYSE, that recovery would result in such violation, and (ii) provide a copy of such opinion to the NYSE; or

(c)recovery would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees, to fail to meet the requirements of Section 401(a)(13) or Section 411(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and U.S. Treasury regulations promulgated thereunder.

5

Section B-4.    Reporting; Disclosure; Monitoring.

The Company shall make all required disclosures and filings with the Regulators with respect to this Policy in accordance with the requirements of the Applicable Rules, and any other requirements applicable to the Company, including the disclosures required in connection with SEC filings.

ARTICLE C.

Discretionary Compensation Clawback Policy for

Certain Acts of Misconduct

Section C-1. Discretionary Recovery on a Covered Event.

In addition to any actions the Committee is required to take under Article B, if a Covered Event occurs with respect to a Covered Person, the Committee may determine whether, and the extent to which, the Company shall recover any erroneously awarded Covered Compensation from the Covered Person. For purposes of this Article C, the amount of erroneously awarded Covered Compensation will be the excess of (i) the Covered Compensation that was granted, Received, vested, settled or distributed to or by the Covered Person (whether in cash or shares) based on the erroneous data that is corrected by the Restatement or that results in the Overstatement over (ii) the Covered Compensation that would have been granted, Received, vested, settled or distributed to or by the Covered Person had such Covered Compensation been based on the correct data and restated results, as applicable. The Committee may determine whether the recovered amount shall be determined without respect to tax liabilities incurred or paid by the Covered Person. The following forms of Covered Compensation, to the extent erroneously awarded, may be recovered from a Covered Person: (a) Covered Compensation that is outstanding (whether vested or unvested) as of the date of the Committee’s Covered Event determination, and

(b) Covered Compensation that is or was Received, vested, settled or distributed (including, in the case of stock options or stock appreciation rights, compensation received upon exercise) during the Recovery Period.

Section C-2. Coverage.

This Article C covers all persons who are Covered Persons at any time during the applicable Recovery Period or the performance period applicable to Covered Compensation. Covered Compensation shall not be recovered under this Article C to the extent Received, vested, settled, or distributed to to such Covered Person before the date the person served as a Covered Person. Subsequent changes in a Covered Person’s employment status, including retirement or termination of employment, do not affect the Company’s right to recover Covered Compensation pursuant to this Article C.

ARTICLE D.

Methods of Recovery

Section D-1. Subject to Section B-3, in the event that the Committee determines that this Policy should apply, to the extent permitted by applicable law, the Company shall, as determined by the Committee in its sole discretion, take any such actions as it deems necessary or appropriate to recover Clawback Compensation. The actions may include, without limitation (and as applicable):

6

(a)forfeit, reduce or cancel any Clawback Compensation (whether vested or unvested) that has not been distributed or otherwise settled;

(b)seek recovery of any Clawback Compensation that was previously paid to the Covered Person;

(c)seek recovery of any amounts realized on the vesting, exercise, settlement, sale, transfer, or other disposition of any equity-based Clawback Compensation;

(d)recoup any amount in respect of Clawback Compensation that was contributed or deferred to a plan that takes into account Clawback Compensation (excluding certain tax-qualified plans, but including deferred compensation plans, and supplemental executive retirement plans, and insurance plans to the extent otherwise permitted by applicable law, including Section 409A of the Code) and any earnings accrued on such Clawback Compensation;

(e)except as otherwise required by Article B, determine whether Clawback Compensation should be recouped on a pre-tax or after-tax basis;

(f)offset, withhold, eliminate or cause to be forfeited any amount that could be paid or awarded to the Covered Person after the date of determination; and

(g)take any other remedial and recovery action permitted by law, as determined by the Committee.

In addition, (x) the Committee may authorize legal action for breach of fiduciary duty or other violation of law and take such other actions to enforce the obligations of the Covered Person to the Company as the Committee deems appropriate or (y) in the event that a Covered Person fails to repay or reimburse erroneously awarded compensation that is subject to recovery, the Committee may require a Covered Person to reimburse the Company for any and all expenses reasonably incurred (including legal fees) by the Company in recovering erroneously awarded compensation under this Policy.

Section D-2. Notice. Before the Company takes action to seek recovery of compensation pursuant to this Policy against a Covered Person, the Company shall take commercially reasonable steps to provide such individual with advance written notice of such clawback; provided that this notice requirement shall not in any way delay the reasonably prompt recovery of any erroneously awarded Incentive-Based Compensation pursuant to Article B.

Section D-3. No Indemnification. The Company shall not indemnify any current or former Covered Person against the loss of erroneously awarded compensation, and shall not pay or reimburse any such person for premiums incurred or paid for any insurance policy to fund such person’s potential recovery obligations.

Description of Business

Description of Business

We are a mortgage and real estate company, providing both credit-related mortgage insurance coverage and an array of other mortgage, risk, title, real estate and real estate technology products and services. We have two reportable business segments—Mortgage Insurance and homegenius.

Mortgage Insurance

Our Mortgage Insurance segment provides credit-related insurance coverage for the benefit of mortgage lending institutions and mortgage credit investors, principally through private mortgage insurance on residential first-lien mortgage loans, and also offers other credit risk management solutions to our customers. We provide our mortgage insurance products and services mainly through our wholly owned subsidiary, Radian Guaranty.

Private mortgage insurance plays an important role in the U.S. housing finance system because it promotes affordable home ownership and helps protect mortgage lenders and mortgage investors, as well as other beneficiaries such as the GSEs, by mitigating default-related losses on residential mortgage loans. Generally, these loans are made to home buyers who make down payments of less than 20% of the purchase price for their home or, in the case of refinancings, have less than 20% equity in their home. Private mortgage insurance also facilitates the sale of these low down payment loans in the secondary mortgage market, almost all of which are currently sold to the GSEs.

Our total direct primary mortgage IIF and RIF were $270.0 billion and $69.7 billion, respectively, as of December 31, 2023, compared to $261.0 billion and $66.1 billion, respectively, as of December 31, 2022.

The GSEs and state insurance regulators impose various capital and financial requirements on our mortgage insurance subsidiaries. These include the PMIERs financial requirements, as well as Risk-to-capital and other risk-based capital measures and surplus requirements. Failure to comply with these capital and financial requirements may limit the amount of insurance that our mortgage insurance subsidiaries write or may prohibit them from writing insurance altogether. The GSEs and state insurance regulators possess significant discretion with respect to our mortgage insurance subsidiaries and all aspects of their business. See Note 16 for additional information on PMIERs and other regulatory information.

homegenius

Our homegenius segment is primarily a fee-for-service business that offers an array of products and services to market participants across the real estate value chain. Our homegenius products and services include title, real estate and real estate technology products and services offered primarily to consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees. These products and services help lenders, investors, consumers and real estate agents evaluate, manage, monitor, acquire and sell properties. They include proprietary platform-as-a-service solutions, as well as other services, such as real estate owned asset management, single-family rental services and real estate valuation services. In addition, we provide title insurance and non-insurance title, closing and settlement services to mortgage lenders, GSEs and mortgage investors, as well as directly to consumers for residential mortgage loans.

See Note 4 for additional information about our reportable segments and All Other business activities, which include the activities and investments associated with Radian Mortgage Capital.

Risks and Uncertainties

In assessing the Company’s current financial condition and developing forecasts of future operations, management has made significant judgments and estimates with respect to potential factors impacting our financial and liquidity position. These judgments and estimates are subject to risks and uncertainties that could affect amounts reported in our financial statements in future periods and that could cause actual results to be materially different from our estimates, including as a result of macroeconomic stresses such as inflation, slower economic growth and higher levels of unemployment.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Basis of Presentation

Our consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation.

We generally refer to our insurance holding company alone, without its consolidated subsidiaries, as “Radian Group.” We refer to Radian Group together with its consolidated subsidiaries as “Radian,” the “Company,” “we,” “us” or “our,” unless the

context requires otherwise. Unless otherwise defined in this report, certain terms and acronyms used throughout this report are defined in the Glossary of Abbreviations and Acronyms included as part of this report.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of our contingent assets and liabilities at the dates of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. While the amounts included in our consolidated financial statements include our best estimates and assumptions, actual results may vary materially.

Investments

We group fixed-maturity securities in our investment portfolio into trading or available for sale securities. Trading securities are reported at fair value, with unrealized gains and losses reported as a separate component of income. Investments in fixed-maturity securities classified as available for sale are reported at fair value, with unrealized gains and losses (net of tax) reported as a separate component of stockholders’ equity as accumulated other comprehensive income (loss).

We also invest in several other types of investments including equity securities, which primarily consist of our interests in a variety of broadly diversified exchange traded funds and are recorded at fair value with unrealized gains and losses reported in income. Mortgage loans held for sale consist of residential mortgage loans, which we purchase with the intention of reselling and have elected to measure at fair value with unrealized gains and losses reported in income. Short-term investments are also carried at fair value and consist of money market instruments, certificates of deposit and highly liquid, interest-bearing instruments with an original maturity of 12 months or less at the time of purchase.

Amortization of premium and accretion of discount are calculated principally using the interest method over the term of the investment. Realized gains and losses on investments are recognized using the specific identification method. See Notes 5 and 6 for further discussion on investments.

We recognize an impairment as a loss for fixed-maturities available for sale on the consolidated statements of operations if: (i) we intend to sell the impaired security; (ii) it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis; or (iii) the present value of cash flows we expect to collect is less than the amortized cost basis of a security. In those instances, we record an impairment loss through earnings that varies depending on specific circumstances. If a sale is likely, the full amount of the impairment is recognized as a loss in the consolidated statements of operations. Otherwise, unrealized losses on securities are separated into: (i) the portion of loss that represents the credit loss and (ii) the portion that is due to other factors. In evaluating whether a decline in value for other securities relates to an existing credit loss, we consider several factors, including, but not limited to, the following:

■the extent to which the amortized cost basis is greater than fair value;

■reasons for the decline in value (e.g., adverse conditions related to industry or geographic area, changes in financial condition to the issuers or underlying loan obligors);

■any changes to the rating of the security by a rating agency;

■the failure of the issuer to make a scheduled payment;

■the financial position, access to capital and near-term prospects of the issuer, including the current and future impact of any specific events; and

■our best estimate of the present value of cash flows expected to be collected.

If a credit loss is determined to exist, the impairment amount is calculated as the difference between the amortized cost and the present value of future expected cash flows, limited to the difference between the carrying amount (i.e., fair value) and amortized cost. This credit loss impairment is included in net gains (losses) on investments and other financial instruments in the consolidated statements of operations, with an offset to an allowance for credit losses. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss impairment or a reversal of credit loss impairment.

Fair Value of Financial Instruments

Our estimated fair value measurements are intended to reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Changes in economic conditions and capital market conditions, including but not limited to, credit spread changes, benchmark interest rate changes, market volatility and changes in the value of underlying collateral, could cause actual results to differ materially from our estimated fair

value measurements. We define fair value as the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

In accordance with GAAP, which establishes a three-level valuation hierarchy, we disclose fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three levels of the fair value hierarchy are defined below:

Level I    —    Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level II    —    Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities; and

Level III    —    Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Level III inputs are used to measure fair value only to the extent that observable inputs are not available.

For markets in which inputs are not observable or are limited, we use significant judgment and assumptions that a typical market participant would use to evaluate the market price of an asset or liability. Given the level of judgment necessary, another market participant may derive a materially different estimate of fair value. These assets and liabilities are classified in Level III of our fair value hierarchy.

Available for sale securities, trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are recorded at fair value as described in Note 5. All changes in fair value of trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are included in our consolidated statements of operations.

Restricted Cash

Included in our restricted cash balances as of December 31, 2023 and 2022, were cash funds held in trusts for the benefit of certain counterparties, primarily as security for the payment and performance of the Company’s obligations.

Accounts and Notes Receivable

Accounts and notes receivable primarily consist of accrued premiums receivable, amounts billed and due from our customers for services performed, and certain receivables related to our reinsurance transactions. Accounts and notes receivable are carried at their estimated collectible amounts, net of any allowance for doubtful accounts, and are periodically evaluated for collectability based on past payment history and current economic conditions. See “Revenue Recognition—Mortgage Insurance” below for information on our deferred premiums and Note 8 for details on our reinsurance agreements.

Income Taxes

We provide for income taxes in accordance with the provisions of the accounting standard regarding accounting for income taxes. As required under this standard, our deferred tax assets and deferred tax liabilities are recognized under the balance sheet method, which recognizes the future tax effect of temporary differences between the amounts recorded in our consolidated financial statements and the tax bases of these amounts. Deferred tax assets and deferred tax liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the periods in which the deferred tax asset or deferred tax liability is expected to be realized or settled. In regard to accumulated other comprehensive income, the Company’s policy for releasing disproportionate income tax effects is to release the effects as individual items are sold.

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance. Our assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods.

See Note 10 for further discussion on income taxes.

Reserve for Losses and LAE

Mortgage Insurance

We establish reserves to provide for losses and LAE on our mortgage insurance policies, which include the estimated costs of settling claims, in accordance with the accounting standard regarding accounting and reporting by insurance enterprises (ASC 944). Although this standard specifically excludes mortgage insurance from its guidance relating to the

reserve for losses, because there is no specific guidance for mortgage insurance, we establish reserves for mortgage insurance as described below, using the guidance contained in this standard supplemented with other accounting guidance.

In our mortgage insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer. Case reserves for losses are established upon receipt of notification from servicers that a borrower has missed two monthly payments, which is when we consider a loan to be in default for financial statement and internal tracking purposes. We also establish reserves for associated LAE, consisting of the estimated cost of the claims administration process, including legal and other fees and expenses associated with administering the claims process.

We do not establish reserves for loans that are in default if we believe that we will not be liable for the payment of a claim with respect to that default. We generally do not establish loss reserves for expected future claims on insured mortgages that are not in default. See “Reserve for Premium Deficiency” below for an exception to these general principles.

With respect to loans that are in default, considerable judgment is exercised as to the adequacy of reserve levels. We use an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. The Default to Claim Rate also includes our estimates with respect to expected Loss Mitigation Activities, which have the effect of reducing our Default to Claim Rates.

After estimating the Default to Claim Rate, we estimate Claim Severity based on observed severity rates within product type, type of insurance and Time in Default cohorts. These severity estimates are then applied to individual loan coverage amounts to determine reserves.

Rescissions, Claim Denials and Claim Curtailments may occur for various reasons, including, without limitation, underwriting negligence, fraudulent applications and appraisals, breach of representations and warranties and inadequate documentation, primarily related to our insurance written in years prior to and including 2008. For our Loss Mitigation Activities, we incorporate a process referred to as a claims rebuttal process by which the insured or servicer of loans may challenge our decisions. Our estimate of future Loss Mitigation Activities incorporates our estimates of the likely outcomes of our claims rebuttal process based on historical practices.

Estimating our case reserve for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may not prove to be accurate, especially in the event of an extended economic downturn or a period of market volatility and economic uncertainty. These assumptions require management to use considerable judgment in estimating the rate at which these loans will result in claims and the amount of claims we expect to pay. As such, there is uncertainty around our reserve estimate.

Title Insurance

We establish reserves for estimated future claims payments on our title insurance policies at the time the related policy revenue is recorded. Our title insurance reserve for losses and LAE comprises estimates of both known claims and incurred but unreported claims expected to be paid in the future for policies issued as of the balance sheet date.

We provide for losses associated with these policies based upon our historical experience and other factors. However, by their nature, title claims can often be complex, vary greatly in dollar amounts, vary in number due to economic and market conditions such as an increase in mortgage foreclosures, and involve uncertainties as to ultimate exposure. Due to the length of time over which claim payments are made and regularly occurring changes in underlying economic and market conditions, these estimates are subject to variability.

Reserve for Premium Deficiency

Insurance enterprises are required to establish a premium deficiency reserve if the net present value of the expected future losses and expenses for a particular product line exceeds the net present value of expected future premiums and existing reserves for that product line. We reassess our expectations for premiums, losses and expenses for our mortgage insurance business at least quarterly and update our premium deficiency analyses accordingly. For our mortgage insurance business, we group our mortgage insurance products into two categories: first-lien and second-lien mortgage loans.

We did not require a first-lien or second-lien premium deficiency reserve as of December 31, 2023 or 2022.

Revenue Recognition

Mortgage Insurance

Premiums on mortgage insurance products are written on a recurring basis, either as monthly or annual premiums, or on a multi-year basis as a single premium. Monthly premiums written are earned as coverage is provided each month. For certain monthly policies where the billing is deferred for the first month’s coverage period, currently to the end of the policy, we record a net premium receivable representing the present value of such deferred premiums that we estimate will be collected at that

future date. As of December 31, 2023 and 2022, this net premium receivable was $36 million and $32 million, respectively, representing the present values of $81 million and $77 million, respectively, in contractual deferred monthly premiums, after adjustments for the estimated collectability and timing of future billing. We recognize changes in this receivable based on changes in the estimated amount and timing of such collections, including as a result of changes in observed trends as well as our periodic review of our servicing guide and our operations and collections practices. Given the difference between the present value of the net premium receivable recorded and the contractual premiums due, such changes to the preceding factors could have a material effect on our results of operations in future periods if any changes are implemented.

Annual premiums written are initially recorded as unearned premiums and amortized on a monthly, straight-line basis. Single premiums written are initially recorded as unearned premiums and earned over time based on the anticipated claim payment pattern, which includes historical industry experience and is updated periodically.

When we rescind insurance coverage on a loan, we refund all premiums received in connection with such coverage. When insurance coverage on a loan is canceled due to claim payment, we refund all premiums received since the date of delinquency. When insurance coverage is canceled for a reason other than Rescission or claim payment, all premium that is nonrefundable is immediately earned. Premium revenue is recognized net of our accrual for estimated premium refunds due to Rescissions, claim payments or other factors.

With respect to our reinsurance transactions, ceded premiums written on an annual or multi-year basis are initially set up as prepaid reinsurance and are amortized in a manner consistent with the recognition of income on direct premiums.

Title Insurance and Related Services

Title insurance premiums are recognized as revenue upon closing and completion of the real estate transaction. Premiums generally are calculated with reference to the policy amount. Premiums are charged to customers based on rates predetermined in coordination with each state’s respective Department of Insurance. Such regulations vary from state to state. Premium revenues from agency title operations are primarily comprised of premiums recognized upon title order and completion of real estate transaction closing.

Other title-related fees and income are closely related to title insurance premiums and are primarily associated with managing the closing of real estate transactions. As such, revenue is primarily recognized upon closing of the real estate transaction or completion and billing of services. We offer title services that include tax and title data services; centralized recording services; document retrieval; default curative title services; deed reports; property reports and other real estate or title-related activities. Expenses typically associated with premiums include third-party agent commissions and premium taxes.

Other Products and Services

We recognize revenue representing the transfer of services to customers in an amount that reflects the consideration that we expect to be entitled to receive in exchange for those services, which are recognized as the performance obligations are satisfied. Due to the transactional nature of our business, our services revenue may fluctuate from period to period as transactions are commenced or completed.

Our services and related revenue recognition considerations are primarily as follows:

Real Estate. We provide real estate services, including asset management and valuation services. Asset management services include management of the entire REO disposition process and services such as diligence and underwriting that serve the single-family rental asset class. In certain instances, fees are received at the time that an asset is assigned to Radian for management. These fees are recorded as deferred revenue and are recognized over time based on progress to date and the availability to customers. In addition, we offer a web-based asset management workflow solution to assist in managing REO assets, rental properties, due diligence for bulk acquisitions of multiple properties, loss mitigation efforts and short sales.

For valuation services, we leverage technology and a quality control process to deliver real estate valuation products and services to our customers, which include: appraisal review products; hybrid/ancillary appraisal products; automated valuation products; interactive valuation products; and broker price opinions. Each service qualifies as a separate performance obligation for which revenue is recognized as the service is performed and made available to the client.

Real Estate Technology. We are continuing to develop a growing suite of real estate technology products and services that are designed to facilitate real estate transactions and are provided as proprietary platform-as-a-service solutions. Revenues for these services are recognized over time as the service is provided and made available to the customer.

Mortgage Services. We provide third-party contract underwriting solutions to our mortgage customers. Generally, revenue is recognized when contract underwriting results are made available to the customer or when other related services are completed.

Cost of Services

Cost of services consists primarily of costs paid for employee compensation and related payroll benefits, as well as corresponding travel and related expenses, incurred in providing such services to clients.

Leases

We determine if an arrangement includes a lease at inception, and if it does, we recognize a right-of-use asset and lease liability. Right-of-use assets represent our right to use an underlying asset for the lease term and are recognized net of any payments made or received from the lessor. Lease liabilities represent our obligation to make lease payments and are based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date.

Lease expense is recognized on a straight-line basis over the expected lease term. Lease and non-lease components are generally not accounted for separately.

Our lease agreements primarily relate to operating leases for office space we use in our operations. Certain of our leases include renewal options and/or termination options that we did not consider in the determination of the right-of-use asset or the lease liability as we did not believe it was reasonably certain that we would exercise such options.

We assess our various asset groups, which include right-of-use assets, for changes in grouping and for potential impairment when certain events occur or when there are changes in circumstances, including potential alternative uses. If circumstances require a change in asset groupings or a right-of-use asset to be tested for possible impairment, and the carrying value of the right-of-use asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. See Notes 9 and 13 for additional information on our right-of-use assets and lease liabilities, respectively.

Reinsurance

We cede insurance risk through the use of reinsurance contracts and follow reinsurance accounting for those transactions where significant risk is transferred. Loss reserves and unearned premiums are established before consideration is given to amounts related to our reinsurance agreements.

In accordance with the terms of the QSR Program, rather than making a cash payment or transferring investments for ceded premiums written, Radian Guaranty holds the related amounts to collateralize the reinsurers’ obligations and has established a corresponding funds withheld liability. Any loss recoveries and any potential profit commission to Radian Guaranty will be realized from this account. The reinsurers’ share of earned premiums is paid from this account on a quarterly basis. For our Single Premium QSR Program, this liability also includes an interest credit on funds withheld, which is recorded as ceded premiums at a rate specified in the agreement and, depending on experience under the contract, may be paid to either Radian Guaranty or the reinsurers.

The ceding commission earned for premiums ceded pursuant to this transaction is attributable to other underwriting costs (including any related deferred policy acquisition costs). The unamortized portion of the ceding commission in excess of our related acquisition cost is reflected in other liabilities. Ceded premiums written are recorded on the balance sheet as prepaid reinsurance premiums and amortized to ceded premiums earned in a manner consistent with the recognition of income on direct premiums. See Note 8 for further discussion of our reinsurance transactions.

Variable Interest Entities

In connection with our reinsurance programs for our mortgage insurance business, we may enter into contracts with VIEs. VIEs include corporations, trusts or partnerships in which: (i) the entity has insufficient equity at risk to allow it to finance its activities without additional subordinated financial support or (ii) at-risk equity holders, as a group, do not have the characteristics of a controlling financial interest.

We perform an evaluation to determine whether we are required to consolidate the VIE’s assets and liabilities in our consolidated financial statements, based on whether we are deemed to be the primary beneficiary. The primary beneficiary of a VIE is the variable interest holder that is determined to have the controlling financial interest as a result of having both: (i) the power to direct the activities of a VIE that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses or right to receive benefits from the VIE that potentially could be significant to the VIE. See Note 8 for additional information.

Goodwill and Other Acquired Intangible Assets, Net

Goodwill is an asset representing the estimated future economic benefits arising from the assets we have acquired that were not individually identified and separately recognized. Goodwill is deemed to have an indefinite useful life and is subject to review for impairment annually, or more frequently whenever circumstances indicate potential impairment at the reporting unit

level. A reporting unit represents a business for which discrete financial information is available. We have concluded that we have one reporting unit, our homegenius segment, for purposes of our goodwill impairment assessment. We generally perform our annual goodwill impairment test during the fourth quarter of each year, comparing the carrying value of the reporting unit as of the prior quarter to its estimated fair value. An impairment charge is recognized for any excess of the reporting unit’s carrying amount over the reporting unit’s estimated fair value, up to the full amount of the goodwill allocated to the reporting unit.

The following table shows the changes in the carrying amount of goodwill for the period indicated, which reflect the results of our impairment testing in the fourth quarter of 2023.

Rollforward of goodwill
(In thousands)	Goodwill		Accumulated Impairment Losses		Net
Balance at December 31, 2022	$	9,802	$	—	$	9,802
Impairment losses	—		(9,802)		(9,802)
Balance at December 31, 2023	$	9,802	$	(9,802)	$	—

The calculation of the estimated fair value of goodwill is performed primarily using an income approach and requires the use of significant estimates and assumptions that are highly subjective in nature, such as future expected cash flows, discount rates, attrition rates and market conditions. Included in our estimates and assumptions is the impact of current year profitability, estimated future cash flows and, to a lesser extent, observed competitor declining trends.

The sustained inflationary pressures and higher interest rate environment have negatively impacted our homegenius businesses, resulting in losses due primarily to the decline in industry-wide purchase and refinance volumes. Despite steps taken to align our workforce to the current and expected needs of the business and reduce our operating expenses, we expect this trend to continue to impact the results of our homegenius segment in at least the near-term based on current market conditions and our expectation that overall refinance volumes will remain low. As a result of our updated financial forecast completed in the fourth quarter of 2023 and based on our annual goodwill impairment assessment in the fourth quarter of 2023, we recorded an impairment of the outstanding balance of $10 million. As a result of this impairment, there was no remaining goodwill balance at December 31, 2023.

Our acquired intangible assets, other than goodwill, primarily consist of customer relationships and represent the value of the specifically acquired customer relationships. For financial reporting purposes, intangible assets with finite lives are amortized over their applicable estimated useful lives in a manner that approximates the pattern of expected economic benefit from each intangible asset. All of our other acquired intangible assets have now been fully amortized and, as such, there was no remaining other acquired intangible asset balance at December 31, 2023.

The following is a summary of the gross and net carrying amounts and accumulated amortization (including impairment) of our other acquired intangible assets as of the periods indicated.

Other acquired intangible assets
	December 31, 2023						December 31, 2022
(In thousands)	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Client relationships	$	43,550	$	(43,550)	$	—	$	43,550	$	(38,067)	$	5,483

Property and Equipment

We capitalize certain costs associated with the development of internal-use software and the purchase of property and equipment. Software, property and equipment are carried at cost, net of accumulated depreciation and amortization. Amortization and depreciation are calculated on a straight-line basis over the estimated useful life of the respective assets and commence during the month of our placement of the assets into use.

The estimated useful life used to calculate the amortization of internal-use software is generally seven years. Leasehold improvements are depreciated over the lesser of the estimated useful life of the asset improved or the remaining term of the lease. The estimated useful life used to calculate the depreciation of furniture and equipment is generally three years. Depreciation and amortization expense associated with property and equipment was $15 million for both the years ended December 31, 2023 and 2022, and $16 million for the year ended December 31, 2021.

The following is a summary of the gross and net carrying amounts and accumulated amortization / depreciation (including impairment) of our property and equipment as of the periods indicated. See Note 9 for more information about impairments.

Deferred Policy Acquisition Costs

Incremental, direct costs associated with the successful acquisition of mortgage insurance policies, consisting of compensation, premium tax and other policy issuance and underwriting expenses, are initially deferred and reported as deferred policy acquisition costs. Consistent with industry accounting practice, amortization of these costs for each underwriting year book of business is recognized in proportion to estimated gross profits over the estimated life of the policies.

Estimated gross profits are composed of earned premium, interest income, losses and LAE. Estimates of expected gross profit, including the Persistency Rate and loss development assumptions for each underwriting year used as a basis for amortization, are evaluated quarterly and the total amortization recorded to date is adjusted by a charge or credit to our consolidated statements of operations if actual experience or other evidence suggests that previous estimates should be revised. Considerable judgment is used in evaluating these estimates and the assumptions on which they are based. The use of different assumptions may have a significant effect on the amortization of deferred policy acquisition costs.

Ceding commissions received under our reinsurance arrangements related to these costs are also deferred and accounted for using similar assumptions. See Note 8 for additional information.

Earnings Per Share

Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, while diluted net income per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and the weighted-average number of dilutive potential common shares.

Dilutive potential common shares relate primarily to our share-based compensation arrangements. In computing diluted net income per share, we use the treasury stock method, which is computed by assuming the issuance of common stock for the potential dilution of our unvested RSUs. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income.

Share-Based Compensation

The cost related to share-based equity instruments is measured based on the grant-date fair value at the date of issuance, which for RSU awards is primarily determined by our common stock price on the date of grant. For share-based awards with performance conditions related to our own operations, the expense recognized is dependent on the probability of the performance measure being achieved. Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. Any forfeitures of awards are recognized as they occur. See Note 17 for further information.

Recent Accounting Pronouncements

Accounting Standards Adopted During 2023

In August 2018, the FASB issued ASU 2018-12, Financial Services—Insurance—Targeted Improvements to the Accounting for Long-Duration Contracts. The new standard: (i) requires that assumptions used to measure the liability for future policy benefits be reviewed at least annually; (ii) defines and simplifies the measurement of market risk benefits; (iii) simplifies the amortization of deferred acquisition costs; and (iv) enhances the required disclosures about long-duration

contracts. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The adoption of this update on January 1, 2023, did not have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform—Facilitation of the Effects of Reference Reform on Financial Reporting. This guidance provides optional expedients and exceptions for applying GAAP requirements to investments, derivatives or other transactions affected by reference rate reform such as those that impact the assessment of contract modifications. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform—Deferral of the Sunset Date of Topic 848, which extends the period of time that preparers can utilize the reference rate reform relief guidance. The prospective adoption of this update on July 1, 2023, did not have a material impact on our consolidated financial statements or disclosures.

Accounting Standards Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements—Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The amendments in this update modify disclosure and presentation requirements related to various topics and align codification with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirements, the pending content will be removed and not become effective. Early adoption is prohibited. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures. This update enhances disclosure requirements, primarily through enhanced disclosures about significant reportable segment expenses under ASC 280. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2023, and interim periods within fiscal periods commencing after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied retrospectively for all periods presented in the financial statements. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures, an update which enhances income tax disclosures. This guidance requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

We have two strategic business units that we manage separately—Mortgage Insurance and homegenius. Our Mortgage Insurance segment derives its revenue from mortgage insurance and other mortgage and risk services, including contract underwriting solutions provided to mortgage lending institutions and mortgage credit investors. Our homegenius segment offers an array of title, real estate and real estate technology products and services to consumers, mortgage lenders, mortgage and real estate investors, GSEs, real estate brokers and agents, and corporations for their employees.

In addition, we report as All Other activities that include: (i) income (losses) from assets held by Radian Group, our holding company; (ii) related general corporate operating expenses not attributable or allocated to our reportable segments; and (iii) certain new business opportunities and other immaterial activities, the majority of which are currently activities associated with our mortgage conduit business conducted through Radian Mortgage Capital.

We allocate corporate operating expenses to our reportable segments and other immaterial operating segments included in All Other based primarily on each segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of management time spent on each segment. In addition, we allocate all corporate interest expense to our Mortgage Insurance segment, due to the capital-intensive nature of our mortgage insurance business. We do not manage assets by segment.

See Note 1 for additional details about our Mortgage Insurance and homegenius businesses.

Adjusted Pretax Operating Income (Loss)

Our senior management, including our Chief Executive Officer (Radian’s chief operating decision maker), uses adjusted pretax operating income (loss) as our primary measure to evaluate the fundamental financial performance of each of Radian’s business segments and to allocate resources to the segments.

Adjusted pretax operating income (loss) is defined as pretax income (loss) excluding the effects of: (i) net gains (losses) on investments and other financial instruments, except for certain investments and other financial instruments attributable to our reportable segments and All Other activities; (ii) amortization and impairment of goodwill and other acquired intangible assets; and (iii) impairment of other long-lived assets and other non-operating items, if any, such as gains (losses) from the sale of lines of business, acquisition-related income and expenses and gains (losses) on extinguishment of debt.

Although adjusted pretax operating income (loss) excludes certain items that have occurred in the past and are expected to occur in the future, the excluded items represent those that are: (i) not viewed as part of the operating performance of our primary activities or (ii) not expected to result in an economic impact equal to the amount reflected in pretax income (loss). These adjustments, along with the reasons for their treatment, are described below.

(1) Net gains (losses) on investments and other financial instruments. The recognition of realized investment gains or losses can vary significantly across periods as the activity is highly discretionary based on the timing of individual securities sales due to such factors as market opportunities, our tax and capital profile and overall market cycles. Unrealized gains and losses arise primarily from changes in the market value of our investments that are classified as trading or equity securities. These valuation adjustments may not necessarily result in realized economic gains or losses.

Trends in the profitability of our fundamental operating activities can be more clearly identified without the fluctuations of these realized and unrealized gains or losses and changes in fair value of other financial instruments. Except for certain investments and other financial instruments attributable to our reportable segments and All Other activities, we do not view them to be indicative of our fundamental operating activities.

(2)Amortization and impairment of goodwill and other acquired intangible assets. Amortization of acquired intangible assets represents the periodic expense required to amortize the cost of acquired intangible assets over their estimated useful lives. Acquired intangible assets are also periodically reviewed for potential impairment, and impairment adjustments are made whenever appropriate. We do not view these charges as part of the operating performance of our primary activities.

(3)Impairment of other long-lived assets and other non-operating items, if any. Impairment of other long-lived assets and other non-operating items includes activities that we do not view to be indicative of our fundamental operating activities, such as: (i) impairment of internal-use software and other long-lived assets; (ii) gains (losses) from the sale of lines of business; (iii) acquisition-related income and expenses; and (iv) gains (losses) on extinguishment of debt.

The reconciliation of adjusted pretax operating income (loss) for our reportable segments to consolidated pretax income is as follows.

Valuation Methodologies for Assets Measured at Fair Value

We are responsible for the determination of the value of all investments carried at fair value and the supporting methodologies and assumptions. To assist us in this responsibility, we utilize independent third-party valuation service providers to gather, analyze and interpret market information and estimate fair values based upon relevant methodologies and assumptions for various asset classes and individual securities.

We perform monthly quantitative and qualitative analyses on the prices received from third parties to determine whether the prices are reasonable estimates of fair value. Our analysis includes: (i) a review of the methodology used by third-party pricing services; (ii) a comparison of pricing services’ valuations to other independent sources; (iii) a review of month-to-month price fluctuations; and (iv) a comparison of actual purchase and sale transactions with valuations received from third parties. These processes are designed to ensure that our investment values are accurately recorded, that the data inputs and valuation techniques utilized are appropriate and consistently applied and that the assumptions are reasonable and consistent with the objective of determining fair value.

The following are descriptions of our valuation methodologies for financial assets measured at fair value.

U.S. Government and Agency Securities. The fair value of U.S. government and agency securities is estimated using observed market transactions, including broker-dealer quotes and actual trade activity as a basis for valuation. U.S. government and agency securities are categorized in either Level I or Level II of the fair value hierarchy.

State and Municipal Obligations. The fair value of state and municipal obligations is estimated using recent transaction activity, including market observations. Valuation models are used, which incorporate bond structure, yield curve, credit spreads and other factors. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable.

Money Market Instruments. The fair value of money market instruments is based on daily prices, which are published and available to all potential investors and market participants. As such, these securities are categorized in Level I of the fair value hierarchy.

Corporate Bonds and Notes. The fair value of corporate bonds and notes is estimated using recent transaction activity, including market observations. Spread models are used that incorporate issuer and structure characteristics, such as credit risk and early redemption features, where applicable. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable.

Asset-backed and Mortgage-backed Securities. The fair value of these instruments, which include RMBS, CMBS, CLO, Other ABS and mortgage insurance-linked notes, is estimated based on prices of comparable securities and spreads and observable prepayment speeds. These securities are generally categorized in Level II of the fair value hierarchy or in Level III when market-based transaction activity is unavailable. The fair value of any Level III securities is generally estimated by discounting estimated future cash flows.

Foreign Government and Agency Securities. The fair value of foreign government and agency securities is estimated using observed market yields used to create a maturity curve and observed credit spreads from market makers and broker-dealers. These securities are categorized in Level II of the fair value hierarchy.

Equity Securities. The fair value of these securities is generally estimated using observable market data in active markets or bid prices from market makers and broker-dealers. Generally, these securities are categorized in Level I or II of the fair value hierarchy, as observable market data are readily available. Certain equity securities may be categorized in Level III of the fair value hierarchy due to a lack of market-based transaction data or the use of model-based valuations.

Mortgage Loans Held for Sale. The fair value of these mortgage loans is generally estimated using measurements derived from observable market data, adjusted for certain loan-level factors such as loan type, loan amount, note rate, LTV, and expected exit value of the loan. As such, these loans are generally categorized in Level II of the fair value hierarchy.

Other Investments. These securities primarily consist of commercial paper and short-term certificates of deposit, which are categorized in Level II of the fair value hierarchy. The fair value of these investments is estimated using market data for comparable instruments of similar maturity and average yield.

Other Invested Assets. These assets consist of interests in private debt or equity investments. The estimated fair value of these other invested assets is primarily based on the private company’s performance, as well as the terms of the instrument and general market benchmarks. As such, these investments are categorized in Level III of the fair value hierarchy.

Derivative Assets and Liabilities. These instruments include embedded derivatives related to our XOL Program, which are categorized in Level III of the fair value hierarchy. The fair value of these derivatives reflects the present value impact of the variation in investment income on the assets held by the reinsurance trusts and the contractual reference rate used to calculate the reinsurance premiums we will pay. Beginning in 2022, our derivative assets and liabilities also include the fair value of certain forward mortgage loan commitments as well as hedging instruments used to manage interest rate risk related to our investments in mortgage loans held for sale. The Company’s derivative instruments are not designated as accounting hedging instruments, and therefore, changes in fair value are recorded in our consolidated statements of operations. These derivative assets and liabilities are categorized in either Level II or III of the fair value hierarchy.

There were 1,063 and 1,284 securities in an unrealized loss position at December 31, 2023 and 2022, respectively. We determined that these unrealized losses were due to non-credit factors and that, as of December 31, 2023, we did not expect to realize a loss for our investments in an unrealized loss position given our intent and ability to hold these investment securities until recovery of their amortized cost basis. See Note 2 for information regarding our accounting policy for impairments of investments.

Loaned Securities

We participate in a securities lending program whereby we loan certain securities in our investment portfolio to third-party borrowers for short periods of time. These securities lending agreements are collateralized financing arrangements whereby we transfer securities to third parties through an intermediary in exchange for cash or other securities. However, pursuant to the terms of these agreements, we maintain effective control over all loaned securities. Although we report such securities at fair value within other assets in our consolidated balance sheets, rather than within investments, the detailed information we provide in this Note 6 includes these securities. See Note 5 for additional detail on the loaned securities.

Under our securities lending agreements, the borrower is required to provide to us collateral, consisting of cash or securities, in amounts generally equal to or exceeding: (i) 102% of the value of the loaned securities (105% in the case of foreign securities) or (ii) another agreed-upon percentage not less than 100% of the market value of the loaned securities. Any cash collateral we receive may be invested in liquid assets. Cash collateral, which is reinvested for our benefit by the intermediary in accordance with the investment guidelines contained in the securities lending and collateral agreements, is

reflected in short-term investments, with an offsetting liability recognized in other liabilities for the obligation to return the cash collateral. Securities collateral we receive is held on deposit for the borrower’s benefit and we may not transfer or loan such securities collateral unless the borrower is in default. Therefore, such securities collateral is not reflected in our consolidated financial statements given that the risks and rewards of ownership are not transferred to us from the borrowers.

Fees received and paid in connection with securities lending agreements are recorded in net investment income on the consolidated statements of operations.

All of our securities lending agreements are classified as overnight and revolving. Securities collateral on deposit with us from third-party borrowers totaling $61 million and $16 million as of December 31, 2023 and 2022, respectively, may not be transferred or re-pledged unless the third-party borrower is in default, and is therefore not reflected in our consolidated financial statements.

Mortgage Loans Held for Sale

Mortgage Loans Held for Sale

The carrying value of mortgage loans held for sale owned by Radian Mortgage Capital totaled $33 million and $4 million at December 31, 2023 and 2022, respectively, and is based on fair value. The estimated fair value of our mortgage loans held for sale is subject to changes in mortgage interest rates from the closing or purchased date through the date of the sale into the secondary market. We elected the fair value option for our mortgage loans held for sale to mitigate income statement volatility and allow for consistent treatment of both loans and any associated hedges or derivatives. Net gains (losses) associated with our mortgage loans held for sale and any related hedges are included in net gains (losses) on investments and other financial instruments on our consolidated statements of operations. See Note 5 for additional information about the fair value of these financial instruments.

As of December 31, 2023, our mortgage loans held for sale consisted of 72 mortgage loans with a total unpaid principal balance of $32 million, related to properties in 24 states and the District of Columbia. As of December 31, 2023, none of these loans were greater than ninety days delinquent or in nonaccrual status. Interest earned on mortgage loans held for sale is included in net investment income on our consolidated statements of operations.

Further, as of December 31, 2023, the Company had commitments to purchase and fund additional mortgage loans with a total unpaid principal balance of $84 million. Prior to the settlement and funding of these loan purchases, any unrealized net gains (losses) related to these commitments are recorded as derivative assets or liabilities on our consolidated balance sheets.

The following table reflects the outstanding derivative instruments used to hedge our mortgage loan activity as of the dates indicated.

Reinsurance

Reinsurance

In our mortgage insurance and title insurance businesses, we use reinsurance as part of our risk distribution strategy, including to manage our capital position and risk profile. The reinsurance arrangements for our mortgage insurance business include premiums ceded under the QSR Program and the XOL Program. The amount of credit that we receive under the PMIERs financial requirements for our third-party reinsurance transactions is subject to ongoing review and approval by the GSEs.

The effect of all of our reinsurance programs on our net income is as follows.

QSR Program

2023 and 2022 QSR Agreements

Radian Guaranty entered into each of the 2023 and 2022 QSR Agreements with panels of third-party reinsurance providers to cede a contractual quota share percentage of certain of our NIW, which includes both Recurring Premium Policies and Single Premium Policies (as set forth in the table below), subject to certain conditions, including a limitation for the 2023 QSR Agreement on ceded RIF equal to $3.0 billion over the term of the agreement.

Radian Guaranty receives a ceding commission for ceded premiums earned pursuant to these transactions. Radian Guaranty is also entitled to receive a profit commission quarterly, subject to a final annual re-calculation, provided that the loss ratio on the loans covered under the agreements generally remains below the applicable prescribed thresholds. Losses on the ceded risk up to these thresholds reduce Radian Guaranty’s profit commission on a dollar-for-dollar basis.

Radian Guaranty may discontinue ceding new policies under the 2023 QSR Agreement at the end of any calendar quarter. As of July 1, 2023, Radian Guaranty is no longer ceding NIW under the 2022 QSR Agreement.

Single Premium QSR Program

Radian Guaranty entered into each of the 2016 Single Premium QSR Agreement, 2018 Single Premium QSR Agreement and 2020 Single Premium QSR Agreement with panels of third-party reinsurers to cede a contractual quota share percentage of our Single Premium NIW as of the effective date of each agreement (as set forth in the table below), subject to certain conditions.

Radian Guaranty receives a ceding commission for ceded premiums written pursuant to these transactions. Radian Guaranty also receives a profit commission annually, provided that the loss ratio on the loans covered under the agreement

generally remains below the applicable prescribed thresholds. Losses on the ceded risk up to these thresholds reduce Radian Guaranty’s profit commission on a dollar-for-dollar basis.

As of January 1, 2022, Radian Guaranty is no longer ceding NIW under the Single Premium QSR Program.

2012 QSR Agreements

In 2012, Radian Guaranty entered into the 2012 QSR Agreements with a third-party reinsurance provider. Radian Guaranty has ceded the maximum amount permitted under the 2012 QSR Agreements and is no longer ceding NIW under this program. RIF ceded under the 2012 QSR Agreements was $100 million and $142 million as of December 31, 2023 and 2022, respectively.

The following table sets forth additional details regarding the QSR Program, with RIF ceded as of the dates indicated.

(2)Radian Guaranty has the option, based on certain conditions and subject to a termination fee, to terminate any of the agreements at the end of any calendar quarter on or after the applicable optional termination date. If Radian Guaranty exercises this option in the future, it would result in Radian Guaranty reassuming the related RIF in exchange for a net payment to the reinsurers calculated in accordance with the terms of the applicable agreement. Radian Guaranty also may terminate any of the agreements prior to the scheduled termination date under certain circumstances, including if one or both of the GSEs no longer grant full PMIERs credit for the reinsurance.

XOL Program

Mortgage Insurance-linked Notes

Radian Guaranty has entered into a number of fully collateralized reinsurance arrangements with the Eagle Re Issuers, as described below. For the respective coverage periods, Radian Guaranty retains the first-loss layer of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amounts. The Eagle Re Issuers provide second layer coverage up to the outstanding coverage amounts. For each of these reinsurance arrangements, the Eagle Re Issuers financed their coverage by issuing mortgage insurance-linked notes to eligible capital markets investors in unregistered private offerings.

The aggregate excess-of-loss reinsurance coverage for these arrangements decreases over the maturity period of the mortgage insurance-linked notes (either a 10-year or 12.5-year period depending on the transaction) as the principal balances of the underlying covered mortgages decrease and as any claims are paid by the applicable Eagle Re Issuer or the mortgage insurance is canceled. Radian Guaranty has rights to terminate the reinsurance agreements upon the occurrence of certain events, including an optional call feature that provides Radian Guaranty the right to terminate the transaction on or after the optional call date (5 or 7 years after the issuance of the mortgage insurance-linked notes depending on the transaction) and a right to exercise an optional clean-up call if the outstanding principal amount of the related mortgage insurance-linked notes falls below 10% of the initial coverage level or principal balance, depending on the transaction, of the related mortgage insurance-linked notes.

Under each of the reinsurance agreements, the outstanding reinsurance coverage amount will begin amortizing after an initial period in which a target level of credit enhancement is obtained and will stop amortizing if certain thresholds, or triggers, are reached, including a delinquency trigger event based on an elevated level of delinquencies as defined in the related mortgage insurance-linked notes transaction agreements.

Given the diminished PMIERs capital benefit and risk mitigation values that Radian Guaranty was receiving from the reinsurance agreements, in June 2023 Eagle Re 2019-1 Ltd. and Eagle Re 2020-1 Ltd. conducted tender offers to purchase the mortgage insurance-linked notes that supported their reinsurance agreements with Radian Guaranty. As a result of the tender offers, $455 million and $332 million of the original principal amount of the Eagle Re 2019-1 Ltd. and Eagle Re 2020-1 Ltd. mortgage insurance-linked notes, respectively, were tendered and repurchased, representing 100% of the Eagle Re 2019-1 Ltd. mortgage insurance-linked notes and 82% of the Eagle Re 2020-1 Ltd. mortgage insurance-linked notes. The corresponding portion of the reinsurance agreements supported by the tendered notes were terminated.

As a result of these tender offers in 2023, Radian Guaranty incurred additional ceded premiums earned of $21 million, consisting of $16 million related to the cost of tender premiums and associated expenses and $5 million related to the acceleration of deferred costs from the original executions of these transactions. Based on projections and expectations in June 2023 at the time of the tender offers, Radian Guaranty expected to save approximately $58 million of future ceded premiums over time as a result of these tenders, including a full recovery of the $21 million of upfront one-time costs noted above within one year.

Upon reaching the five-year optional call date, in November 2023, Radian Guaranty exercised its right to terminate Radian Guaranty’s excess-of-loss reinsurance agreement with Eagle Re 2018-1 Ltd. In connection with the termination of Radian Guaranty’s excess-of-loss reinsurance agreement with Eagle Re 2018-1 Ltd., the mortgage insurance-linked notes issued by Eagle Re 2018-1 Ltd. were redeemed in full with a distribution of remaining collateral assets.

Traditional Reinsurance

For the respective coverage periods under traditional XOL reinsurance agreements, Radian Guaranty retains the first-loss layer of aggregate losses, as well as any losses in excess of the outstanding reinsurance coverage amounts. The reinsurers provide second layer coverage up to the outstanding coverage amounts. Radian Guaranty is then responsible for any losses in excess of the reinsurance coverage amount.

The 2023 XOL Agreement, which was executed in October 2023, is scheduled to terminate September 30, 2033. Radian Guaranty has the option, based on certain conditions, to terminate the agreement as of September 30, 2028, or at the end of any calendar quarter thereafter, which would result in Radian Guaranty reassuming the related RIF. In the event Radian Guaranty does not exercise its right to terminate the agreement on September 30, 2028, the monthly premium rate will increase from the original monthly premium.

The following tables set forth additional details regarding the XOL Program, with RIF, remaining coverage and first layer retention as of the dates indicated.

(1)Excludes Eagle Re 2019-1 Ltd. and Eagle Re 2018-1 Ltd., which as further discussed above, were terminated in June 2023 and November 2023, respectively.

(2)Radian Group purchased $45 million of Eagle Re 2021-1 Ltd. and $2 million of Eagle Re 2020-1 Ltd. outstanding principal amounts of the respective mortgage insurance-linked notes issued in connection with these reinsurance transactions. These notes are included in fixed-maturities available for sale on our consolidated balance sheets at December 31, 2023 and 2022. See Notes 5 and 6 for additional information.

The Eagle Re Issuers are not subsidiaries or affiliates of Radian Guaranty. Based on the accounting guidance that addresses VIEs, we have not consolidated any of the assets and liabilities of the Eagle Re Issuers in our financial statements, because Radian does not have: (i) the power to direct the activities that most significantly affect the Eagle Re Issuers’ economic performances or (ii) the obligation to absorb losses or the right to receive benefits from the Eagle Re Issuers that potentially could be significant to the Eagle Re Issuers. See Note 2 for more information on our accounting treatment of VIEs.

Following the discontinuation of the London Inter-bank Offered Rate (LIBOR), effective June 30, 2023, SOFR is the effective benchmark rate for all of our reinsurance agreements with the Eagle Re Issuers as of December 31, 2023. The reinsurance premium due to the Eagle Re Issuers is calculated by multiplying the outstanding reinsurance coverage amount at the beginning of a period by a coupon rate, which is the sum of SOFR, plus a contractual risk margin, and then subtracting actual investment income collected on the assets in the reinsurance trust during the preceding month. As a result, the premiums we pay will vary based on: (i) the spread between SOFR and the rates on the investments held by the reinsurance trust and (ii) the outstanding amount of reinsurance coverage.

As the reinsurance premium will vary based on changes in these rates, we concluded that the reinsurance agreements contain embedded derivatives, which we have accounted for separately as freestanding derivatives and recorded in other assets or other liabilities on our consolidated balance sheets. Changes in the fair value of these embedded derivatives are recorded in net gains (losses) on investments and other financial instruments on our consolidated statements of operations. See Note 5 herein for more information on our fair value measurements of financial instruments, including our embedded derivatives.

In the event an Eagle Re Issuer is unable to meet its future obligations to us, if any, our insurance subsidiaries would be liable to make claims payments to our policyholders. In the event that all of the assets in the reinsurance trust (consisting of U.S. government money market funds, cash or U.S. Treasury securities) become worthless and the Eagle Re Issuer is unable to make its payments to us, our maximum potential loss would be the amount of mortgage insurance claim payments for losses on the insured policies, net of the aggregate reinsurance payments already received, up to the full aggregate excess-of-loss reinsurance coverage amount. In the same scenario, the related embedded derivative would no longer have value.

The Eagle Re Issuers represent our only VIEs as of the dates indicated. The following table presents the total assets and liabilities of the Eagle Re Issuers as of the dates indicated.

Total VIE assets and liabilities of Eagle Re Issuers (1)

Total	$	964,909	$	1,866,809

(1)Assets held by the Eagle Re Issuers are required to be invested in U.S. government money market funds, cash or U.S. Treasury securities. Liabilities of the Eagle Re Issuers consist of their mortgage insurance-linked notes as described above. Assets and liabilities are equal to each other for each of the Eagle Re Issuers.

Other Collateral

Although we use reinsurance as one of our risk management tools, reinsurance does not relieve us of our obligations to our policyholders. In the event the reinsurers are unable to meet their obligations to us, our insurance subsidiaries would be liable for any defaulted amounts. However, consistent with the PMIERs reinsurer counterparty collateral requirements, Radian Guaranty’s reinsurers have established trusts to help secure our potential cash recoveries. In addition to the total VIE assets of the Eagle Re Issuers discussed above, the amount held in reinsurance trusts was $274 million as of December 31, 2023, compared to $175 million as of December 31, 2022.

In addition, primarily for the Single Premium QSR Program, Radian Guaranty holds amounts related to ceded premiums written to collateralize the reinsurers’ obligations, which is reported in reinsurance funds withheld on our consolidated balance sheets. Any loss recoveries and profit commissions paid to Radian Guaranty related to the Single Premium QSR Program are expected to be realized from this account.

Right-of-Use Assets

During 2021, in response to the COVID-19 pandemic and our transition to a hybrid work environment, we made the decision to exit, and to actively market for sublease, all office space in our former corporate headquarters in downtown Philadelphia. As part of this change, we entered into two new leases with reduced square footage, including our new corporate headquarters, effective September 2021, in Wayne, Pennsylvania and a Cherry Hill, New Jersey location.

As a result of this decision and our ongoing evaluation of all of our existing leases, future space needs and evolving sublease market conditions, we recognized impairments to our right-of-use assets of $5 million and $8 million for the years

ended December 31, 2023 and 2022, respectively. In addition, we recognized impairments to related property and equipment, including leasehold improvements, of $4 million and $5 million for the years ended December 31, 2023 and 2022, respectively. These impairments related primarily to our former corporate headquarters leases and reduced the carrying value of certain lease assets and the related property and equipment to their estimated fair values. The right-of-use asset fair values were estimated using an income approach based on forecasted future cash flows expected to be derived from the property based on projected sublease market rents, which could differ from actual results and require us to revise our estimates in future periods. Following these impairments, which were recorded within other operating expenses on our consolidated statements of operations, the aggregate carrying value of the right-of-use assets and leasehold improvements related to the former corporate headquarters leases was $6 million as of December 31, 2023.

Current and Deferred Taxes

As of both December 31, 2023 and 2022, our current federal income tax liability was $21 million, which primarily relates to applying the standards of accounting for uncertainty in income taxes, and is included as a component of other liabilities in our consolidated balance sheets.

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance, and this assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods. Certain entities within our consolidated group have generated net deferred tax assets relating primarily to state and local NOL carryforwards which, if unutilized, will expire during various future tax periods. We have determined that certain of these entities may continue to generate taxable losses on a separate company basis in the near term and may not be able to fully utilize certain of their state and local NOLs on their state and local tax returns. Therefore, we have concluded a valuation allowance is required with respect to deferred tax assets relating to these state and local NOLs and other state timing adjustments. As of December 31, 2023 and 2022, this valuation allowance was $63 million and $70 million, respectively.

In addition, as of December 31, 2023, we have generated deferred tax assets related to unrealized capital losses, and we consider it more likely than not that these assets will be realized. We will continue to monitor the level of these losses and our overall ability to realize the related deferred tax assets in the coming quarters.

As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, under Internal Revenue Code Section 832(e) for amounts required by state law or regulation to be set aside in statutory contingency reserves. The deduction is allowed only to the extent that, in conjunction with quarterly federal tax payment due dates, we purchase non-interest-bearing U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury in an amount equal to the tax benefit derived from deducting any portion of our statutory contingency reserves. As of December 31, 2023 and 2022, we held $750 million and $596 million, respectively, of these bonds, which are included as prepaid federal income

taxes in our consolidated balance sheets. The corresponding deduction of our statutory contingency reserves resulted in the recognition of a net deferred tax liability. See Note 16 for additional information about our U.S. Mortgage Guaranty Tax and Loss Bonds.

On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022 (“IRA”) which, among other things, implemented a 15% minimum tax on book income of certain large corporations, a 1% excise tax on net stock repurchases that occur after December 31, 2022, and several tax incentives to promote clean energy. The new minimum tax, 1% excise tax and other income tax provisions of the IRA did not have a material impact on the Company.

Unrecognized Tax Benefits

As of December 31, 2023, we have $4 million of net unrecognized tax benefits, including $3 million of interest and penalties, that would affect the effective tax rate if recognized. Our policy for the recognition of interest and penalties associated with uncertain tax positions is to record such items as a component of our income tax provision, of which $776 thousand of expense and $182 thousand of benefit were recorded for the years ended December 31, 2023 and 2022, respectively.

A reconciliation of the beginning and ending gross unrecognized tax benefits is as follows.

Our gross unrecognized tax benefits decreased by $879 thousand from December 31, 2022, to December 31, 2023, primarily as a result of reductions related to lapses of the statute of limitations. Although unrecognized tax benefits decreased due to statute expirations, certain amounts for premium income recognition continued to impact subsequent years, resulting in a corresponding increase in unrecognized tax benefits related to premium income recognition. Over the next 12 months, our unrecognized tax benefits may decrease by approximately $297 thousand due to the expiration of the applicable statute of limitations relating to the 2020 tax year. The statute of limitations related to our federal consolidated income tax return remains open for tax years 2020-2023. Additionally, among the entities within our consolidated group, various tax years remain open to potential examination by state and local taxing authorities.

(1)Related to ceded losses recoverable, if any, on reinsurance transactions. See Note 8 for additional information.

(2)Related to underlying defaulted loans with a most recent default notice dated in the year indicated. For example, if a loan had defaulted in a prior year, but then subsequently cured and later re-defaulted in the current year, that default would be considered a current year default.

Reserve Activity

Incurred Losses

Total incurred losses are driven by: (i) case reserves established for new default notices, which are primarily impacted by both the number of new primary default notices received in the period and our related gross Default to Claim Rate assumption applied to those new defaults and (ii) reserve developments on prior period defaults, which are primarily impacted by changes to our prior Default to Claim Rate assumptions.

New primary default notices totaled 44,007 for the year ended December 31, 2023, compared to 37,738 for the year ended December 31, 2022, and 37,470 for the year ended December 31, 2021.

Our gross Default to Claim Rate assumption applied to new defaults was 8.0% for all periods presented, as we continue to closely monitor the trends in Cures and claims paid for our default inventory, while also weighing the risks and uncertainties associated with the current economic environment.

Our provision for losses during 2023, 2022 and 2021 was positively impacted by favorable reserve development on prior year defaults, primarily as a result of more favorable trends in Cures than originally estimated. These Cures have been due primarily to favorable outcomes resulting from mortgage forbearance programs implemented in response to the COVID-19 pandemic as well as positive trends in home price appreciation, which has also contributed to a higher rate of claims that result in no ultimate loss and that are withdrawn by servicers as a result. These favorable observed trends resulted in reductions in our Default to Claim Rate and other reserve adjustments for prior year default notices. As the remaining number of defaults has continued to decline, the magnitude of the impact to our provision for losses from reserve development on prior year defaults has declined as well.

Default to Claim Rate

Our Default to Claim Rate estimates on defaulted loans are mainly developed based on the Stage of Default and Time in Default of the underlying defaulted loans grouped according to the period in which the default occurred, as measured by the progress toward foreclosure sale and the number of months in default. During 2023 and 2022, the ongoing favorable trend in Cures resulting from the positive effects of mortgage forbearance programs and the positive trends in home price appreciation contributed to reductions in our claims paid, including as a result of an increase in the number of claims that are withdrawn by servicers with no ultimate loss, which in turn led to a reduction in our Default to Claim Rates and other reserve assumptions.

The following table shows our gross Default to Claim Rates on our primary portfolio based on the Time in Default and as of the dates indicated.

Default to Claim Rates
	December 31,
	2023		2022		2021
Default to Claim Rate on:
New defaults	8.0	%	8.0	%	8.0	%
Defaults not in Foreclosure Stage
Time in Default: < 2 years (1)	21.0	%	21.8	%	41.6	%
Time in Default: 2 - 5 years	55.0	%	65.0	%	75.0	%
Time in Default: > 5 years	60.0	%	70.0	%	80.0	%
Foreclosure Stage Defaults	65.0	%	75.0	%	85.0	%

(1)Represents the weighted average Default to Claim Rate for all defaults not in foreclosure stage that have been in default for up to two years, including new defaults. The estimated Default to Claim Rates applied to defaults within this population vary by Time in Default, and range from the Default to Claim Rates on new defaults shown above, up to 50.0%, 55.0% and 80.1% for more aged defaults in this category as of December 31, 2023, 2022 and 2021, respectively.

Our estimate of expected Rescissions, Claim Denials and claim withdrawals (net of expected Reinstatements) is then applied to our estimated gross Default to Claim Rates and is generally based on our recent experience. Consideration is also given to differences in characteristics between those rescinded policies, denied claims and claim withdrawals and the loans remaining in our defaulted inventory.

Claims Paid

Total claims paid decreased in 2023 compared to 2022. The decrease in claims paid is primarily attributable to a reduction in commutations and settlements.

Concentration of Risk

As of December 31, 2023, Texas accounted for 10% of our mortgage insurance business measured by primary RIF, as compared to no states at or above this measure as of December 31, 2022. Texas accounted for 13% and 12% of our direct NIW for the years ended December 31, 2023 and 2022, respectively, while California accounted for 11% for the year ended December 31, 2021.

Additional Disclosures

The following tables provide information as of and for the periods indicated about: (i) incurred losses, net of reinsurance; (ii) the total of IBNR liabilities plus expected development on reported claims, included within the net incurred loss amounts; (iii) the cumulative number of reported defaults; and (iv) cumulative paid claims, net of reinsurance. The default year represents the period that a new default notice is first reported to us by loan servicers, related to borrowers who missed two monthly payments.

The information about net incurred losses and paid claims development for the years ended prior to 2023 is presented as supplementary information.

(2)Represents total number of new primary default notices received in each calendar year as compiled monthly based on reports received from loan servicers. As reflected in our Default to Claim Rate assumptions, a significant portion of reported defaults generally do not result in a claim. In certain instances, a defaulted loan may cure, and then re-default in a later period. Consistent with our reserving practice, each new event of default is treated as a unique occurrence and therefore certain loans that cure and re-default may be included as a reported default in multiple periods.

Redemption Terms in Senior Notes. We have the option to redeem the Senior Notes due 2024, 2025 and 2027, in whole or in part, at any time, or from time to time, prior to July 1, 2024 (the date that is three months prior to the maturity date of the Senior notes due 2024), September 15, 2024 (the date that is six months prior to the maturity date of the Senior notes due 2025) and September 15, 2026 (the date that is six months prior to the maturity date of the Senior notes due 2027) (in each case, the “Par Call Date”), respectively, at a redemption price equal to the greater of: (i) 100% of the aggregate principal amount of the notes to be redeemed and (ii) the make-whole amount, which is the sum of the present values of the remaining scheduled payments of principal and interest in respect of the notes to be redeemed from the redemption date to the Par Call Date discounted to the redemption date at the applicable treasury rate plus 50 basis points, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date. At any time on or after the Par Call Date, we may, at our option, redeem the notes in whole or in part, at a redemption price equal to 100% of the aggregate principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date.

Covenants in Senior Notes. The indentures governing the Senior Notes due 2024, 2025 and 2027 contain covenants customary for securities of this nature, including covenants related to the payments of the notes, periodic reporting and certificates to be issued and covenants related to amendments to the indentures. Additionally, the indentures include covenants restricting us from encumbering the capital stock of a designated subsidiary (as defined in the indenture for the

notes) or disposing of any capital stock of any designated subsidiary unless either all of the stock is disposed of or we retain more than 80% of the stock. We were in compliance with all covenants as of December 31, 2023.

FHLB Advances

Radian Guaranty is a member of the FHLB. As a member, it may borrow from the FHLB, subject to certain conditions, which include the need to post collateral and the requirement to maintain a minimum investment in FHLB stock, in part depending on the level of its outstanding FHLB advances.

Interest on the FHLB advances is primarily fixed-rate and is payable quarterly, or at maturity if the term of the advance is less than 90 days. Principal is due at maturity. For obligations with maturities greater than or equal to 90 days, we may prepay the debt at any time, subject to paying a prepayment fee.

The principal balance of the FHLB advances is required to be collateralized by eligible assets with a fair value that must be maintained generally within a minimum range of 103% to 114% of the amount borrowed, depending on the type of assets pledged. Our fixed-maturities available for sale and trading securities include securities totaling $101 million and $164 million at December 31, 2023 and 2022, respectively, which serve as collateral for our FHLB advances to satisfy this requirement.

Mortgage Loan Financing Facilities

In 2022, Radian Mortgage Capital entered into the BMO Master Repurchase Agreement and the Goldman Sachs Master Repurchase Agreement to finance the acquisition of residential mortgage loans and related mortgage loan assets. The Goldman Sachs Master Repurchase Agreement is an uncommitted mortgage loan repurchase facility that initially had a maximum borrowing amount of $300 million and was amended in July 2023 to reduce the maximum borrowing amount to $100 million. The BMO Master Repurchase Agreement, which is also uncommitted, initially had a maximum borrowing amount of $300 million and was amended in April 2023 to reduce the maximum borrowing amount to $150 million. The Goldman Sachs Master Repurchase Agreement and the BMO Master Repurchase Agreement are currently scheduled to expire on September 14, 2024, and September 25, 2024, respectively.

In January 2024, Radian Mortgage Capital entered into a master repurchase agreement with Flagstar Bank, N.A. (“Flagstar”). This agreement is an uncommitted mortgage loan repurchase facility with a maximum borrowing amount of $150 million pursuant to which Radian Mortgage Capital may from time to time sell to Flagstar, and later repurchase, certain residential mortgage loan assets. The Flagstar Master Repurchase Agreement is scheduled to expire on January 27, 2025.

The Master Repurchase Agreements are uncommitted, and Goldman Sachs Bank USA (“Goldman Sachs”), Bank of Montreal, a Canadian chartered bank acting through its Chicago branch (“BMO”) and Flagstar are under no obligation to fund the purchase of any residential mortgage loan assets under their respective agreements. In the event Goldman Sachs, BMO or Flagstar advances funds to purchase residential mortgage loan assets, the amount of such advances generally will be calculated as a percentage of the unpaid principal balance or market value of the residential mortgage loan assets, depending on the credit characteristics of the loans being purchased.

As of December 31, 2023, there were $21 million and $3 million of outstanding borrowings under the BMO Master Repurchase Agreement and the Goldman Sachs Master Repurchase Agreement, respectively. Of our mortgage loans held for sale, $31 million and $2 million at December 31, 2023 and 2022, respectively, served as collateral for the Master Repurchase Agreements to support the funds advanced.

The borrowings under the Master Repurchase Agreements bear a variable interest rate based on one-month SOFR or compounded SOFR, depending on the agreement, plus an applicable margin, with interest payable monthly. Principal is due upon the earliest of the sale or disposition of the related mortgage loans, the occurrence of certain default or acceleration events or at the termination date of the applicable Master Repurchase Agreement.

The Master Repurchase Agreements contain provisions that provide Goldman Sachs, BMO and Flagstar, respectively, with certain rights in the event of a decline in the market value of the purchased residential mortgage loan assets. Under these provisions, Radian Liberty Funding or Radian Mortgage Capital, as applicable, may be required to transfer cash or additional eligible residential mortgage loan assets with an aggregate market value that is equal to the difference between the value of the residential mortgage loan assets then subject to the applicable Master Repurchase Agreement and a minimum threshold amount.

Radian Group has entered into the Parent Guarantees to guaranty the obligations of certain of its subsidiaries in connection with the Master Repurchase Agreements described above.

Pursuant to the Parent Guarantees, Radian Group is subject to negative and affirmative covenants customary for this type of financing transaction, including, among others, limitations on the incurrence of debt and restrictions on certain transactions with affiliates, payments and investments and various financial covenants that the Company must remain in compliance with, including those related to: (i) the total adjusted capital of the Company’s primary mortgage insurance subsidiary, currently Radian Guaranty; (ii) the Company’s minimum consolidated net worth; and (iii) the Company’s maximum Debt-to-Total Capitalization Ratio (as defined in the Parent Guarantees). The covenants and financial covenants in the Parent

Guarantees are generally consistent with the comparable covenants in the Company’s revolving credit facility, including with respect to the payment of dividends on shares of its common stock which are permitted under the revolving credit facility and the Master Repurchase Agreements so long as no default or event of default exists and the Company is in pro forma compliance with the applicable financial covenants on the date a dividend is declared. As of December 31, 2023, we are in compliance with all of the debt covenants under our mortgage loan financing facilities.

Revolving Credit Facility

Radian Group has in place a $275 million unsecured revolving credit facility with a syndicate of bank lenders. The revolving credit facility matures in December 2026, although under certain conditions Radian Group may need to offer to repay any outstanding amounts and terminate lender commitments earlier than the maturity date. Terms of the credit facility include an accordion feature that allows Radian Group, at its option, to increase the total borrowing capacity during the term of the agreement, subject to our obtaining the necessary increased commitments from lenders (which may include then existing or other lenders), up to a total of $400 million.

Subject to certain limitations, borrowings under the credit facility may be used for working capital and general corporate purposes, including capital contributions to Radian Group’s insurance and other subsidiaries as well as growth initiatives. The credit facility contains customary representations, warranties, covenants, terms and conditions. Our ability to borrow under the credit facility is conditioned on the satisfaction of certain financial and other covenants, including covenants related to minimum net worth and statutory surplus, a maximum debt-to-capitalization level, limits on certain types of indebtedness and liens, and Radian Guaranty’s eligibility as a private mortgage insurer with the GSEs. At December 31, 2023, Radian Group was in compliance with all the covenants and there were no amounts outstanding under this revolving credit facility.

In connection with these matters, from time to time we receive requests and subpoenas seeking information and documents related to aspects of our business. Our Master Policies establish the timeline within which any suit or action arising from any right of an insured under the policy generally must be commenced. In general, any suit or action arising from any right of an insured under the policy must be commenced within two years after such right first arose for primary insurance and within three years for certain other policies, including certain Pool Mortgage Insurance policies. Although we believe that our Loss Mitigation Activities are justified under our policies, from time to time we face challenges from certain lender and servicer customers regarding our Loss Mitigation Activities. These challenges could result in additional arbitration or judicial proceedings and we may need to reassume the risk on, and increase loss reserves for, the associated policies or pay additional claims.

In the course of our regular review of pending legal actions and proceedings, we determine whether it is reasonably possible that a potential loss may have a material impact on our liquidity, results of operations or financial condition. If we determine such a loss is reasonably possible, we disclose information relating to such potential loss, including an estimate or range of loss or a statement that such an estimate cannot be made. On a quarterly basis, we review relevant information with respect to loss contingencies and update our accruals, disclosures and estimates of reasonably possible losses or range of losses based on such reviews. We are often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from other parties and investigation of factual allegations, rulings by the court on motions or appeals, analysis by experts and the progress of settlement negotiations. In addition, we generally make no disclosures for loss contingencies that are determined to be remote. For matters for which we disclose an estimated loss, the disclosed estimate reflects the reasonably possible loss or range of loss in excess of the amount accrued, if any.

Management believes, based on current knowledge and after consultation with counsel, that the outcome of currently pending or threatened actions will not have a material adverse effect on our consolidated financial condition or results of operations. The outcome of legal actions and proceedings is inherently uncertain, and it is possible that any one or more matters could have an adverse effect on our liquidity, financial condition or results of operations for any particular period. In accordance with applicable accounting standards and guidance, we establish accruals only when we determine both that it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. We accrue the amount that represents our best estimate of the probable loss; however, if we can only determine a range of estimated losses, we accrue an amount within the range that, in our judgment, reflects the most likely outcome, and if none of the estimates within the range is more likely, we accrue the minimum amount of the range.

Legal actions and proceedings could result in adverse judgments, settlements, fines, injunctions, restitutions or other relief that could require significant expenditures or have other effects on our business in excess of amounts we have established as reserves for such matters. Loss estimates are inherently subjective, based on currently available information and are subject to management’s judgment and various assumptions. Due to the inherently subjective nature of these estimates and the uncertainty and unpredictability surrounding the outcome of legal and other proceedings, actual results may differ materially from any amounts that have been accrued.

Lease Liability

Our lease liability represents the present value of future lease payments over the lease term. Our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our incremental borrowing rate, on a collateralized basis, to discount the lease payments based on information available at lease commencement. Our leases expire periodically through August 2032 and contain provisions for scheduled periodic rent increases. We estimate the incremental borrowing rate based on the yields of Radian Group corporate bonds, as adjusted to reflect a collateralized borrowing rate, resulting in discount rates ranging from 4.8% to 7.5%. While the majority of our lease population expires within one year of one of Radian Group’s corporate bonds, our more significant leases do not. For those leases, we adjust the corporate bond rate for both U.S. Department of the Treasury rate yields, and a corporate spread adjustment determined from recent market data.

The following tables provide additional information related to our leases, including: (i) the components of our total lease cost; (ii) the cash flows arising from our lease transactions; (iii) supplemental balance sheet information; (iv) the weighted-average remaining lease term; (v) the weighted-average discount rate used for our leases; and (vi) the remaining maturities of our lease liabilities, as of and for the periods indicated.

We entered into a sublease agreement in January 2022 for a portion of the office space in our former corporate headquarters in Philadelphia and are actively marketing additional space in that location for sublease. Upon entering a sublease agreement, we generally do not anticipate being relieved of our primary obligation under the original lease and will act as a lessor recognizing any sublease income on a straight-line basis over the remaining lease term as an offset to other operating expenses.

Other

We provide contract underwriting to our mortgage insurance customers, pursuant to which we offer limited indemnification remedies. In 2023 and 2022, our provision for contract underwriting expenses and our payments for losses related to contract underwriting remedies were de minimis. We monitor this risk and negotiate our underwriting fee structure and recourse agreements on a client-by-client basis. We also routinely audit the performance of our contract underwriters.

Share Repurchase Activity

From time to time, Radian Group’s board of directors approves share repurchase programs authorizing the Company to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Radian generally operates its share repurchase programs pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which provides for share repurchases at predetermined price targets and permits the Company to purchase shares when it may otherwise be precluded from doing so.

In January 2023, Radian Group’s board of directors approved a share repurchase program authorizing the Company to spend up to $300 million, excluding commissions, to repurchase Radian Group common stock in the open market or in privately negotiated transactions, based on market and business conditions, stock price and other factors. Radian has implemented a trading plan under Rule 10b5-1 of the Exchange Act. The authorization will expire in January 2025. During the year ended December 31, 2023, the Company purchased 5.3 million shares at an average price of $25.32 per share, including commissions. As of December 31, 2023, purchase authority of up to $167 million remained available under this share repurchase program.

The Inflation Reduction Act of 2022 imposed a nondeductible 1% excise tax on the net value of certain stock repurchases made after December 31, 2022. All dollar amounts presented in this report related to our share repurchases and our share repurchase authorizations exclude such excise taxes, to the extent applicable, unless otherwise indicated. See Note 10 for additional information on this excise tax.

Other Purchases

We may purchase shares on the open market to settle stock options exercised by employees. In addition, upon the vesting of certain RSUs under our equity compensation plans, we may withhold from such vested awards shares of our common stock to satisfy the tax liability of the award recipients.

Dividends and Dividend Equivalents

The following table presents the amount of dividends declared and paid, on a per share basis, for each quarter and annual period as indicated.

In February 2024, Radian Group’s board of directors authorized an increase in the Company’s quarterly dividend from $0.225 to $0.245 per share for the first quarter of 2024.

Dividend equivalents are accrued on RSUs when dividends are declared on the Company’s common stock, subject to certain exclusions. See Note 17 for information about our dividend equivalents on RSU awards.

Statutory Information

Dec. 31, 2023

SEC Schedule, 12-16, Insurance Companies, Supplementary Insurance Information [Abstract]

Statutory Information

Statutory Information

Radian Group serves as the holding company for our insurance subsidiaries, through which we conduct our mortgage insurance and title insurance businesses. These insurance subsidiaries are subject to comprehensive, detailed regulation by the insurance departments in the various states where our insurance subsidiaries are domiciled or licensed to transact business. Insurance laws vary from state to state, but generally grant broad supervisory powers to state agencies or officials to examine insurance companies and enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including the power to revoke or restrict an insurance company’s ability to write new business.

All of our mortgage insurance subsidiaries are domiciled in Pennsylvania. We currently write new mortgage insurance business using only one principal subsidiary, Radian Guaranty. Radian Guaranty is authorized as a monoline insurer to write mortgage guaranty insurance (or in states where there is no specific authorization for mortgage guaranty insurance, the applicable line of insurance under which mortgage guaranty insurance is regulated) in all 50 states, the District of Columbia and Guam.

As part of our title services, we offer title insurance through Radian Title Insurance, which is domiciled in Ohio and licensed to issue title insurance policies in 41 states and the District of Columbia.

In addition to complying with state insurance regulations, in order to be eligible to insure loans purchased by the GSEs, mortgage insurers such as Radian Guaranty must meet the GSEs’ eligibility requirements, or PMIERs. The PMIERs are comprehensive, covering virtually all aspects of the business and operations of a private mortgage insurer, including internal

risk management and quality controls, the relationship between the GSEs and the approved insurer, as well as the approved insurer’s financial condition. See “PMIERs” below for additional information.

The PMIERs and state insurance regulations include various capital requirements and dividend restrictions based on our insurance subsidiaries’ statutory financial position and results of operations, as described below. Our failure to maintain adequate levels of capital could lead to intervention by the various insurance regulatory authorities, which could materially and adversely affect our business, business prospects and financial condition.

Statutory Financial Statements

We prepare our statutory financial statements in accordance with the accounting practices required or permitted, if applicable, by the insurance departments of the respective states of domicile of our insurance subsidiaries. Required SAP are established by the NAIC, as well as state laws, regulations and general administrative rules. In addition, insurance departments have the right to permit other specific practices that may deviate from prescribed practices. As of December 31, 2023, we did not have any prescribed or permitted SAP that resulted in reported statutory surplus or risk-based capital being materially different from what would have been reported had NAIC statutory accounting practices been followed.

Reflecting the principal differences between SAP and GAAP, statutory financial statements typically do not include unrealized gains or losses on fixed-maturity securities, deferred policy acquisition costs, certain net deferred tax assets and certain other less readily marketable assets that are designated as non-admitted assets. In addition to these general differences, SAP also requires that mortgage insurance companies establish a special contingency reserve equal to 50% of premiums earned in each year, generally to be maintained for 10 years, to protect policyholders against loss during adverse economic cycles.

As a result of the requirement to establish and maintain this statutory liability, contingency reserves affect the ability of a mortgage insurer to pay dividends, as described below. With regulatory approval, a mortgage insurance company may make early withdrawals from this contingency reserve when incurred losses exceed 35% of net premiums in a calendar year. During 2023, Radian Guaranty released $21 million from its contingency reserves due to the expiration of the 10-year holding requirement for the remaining contingency reserves established during 2013. Radian Guaranty did not release any amounts from its contingency reserves in 2022. Based on the typical 10-year holding requirement, Radian Guaranty is scheduled to release contingency reserves to unassigned surplus in material amounts beginning in 2024. See “Statutory Dividend Restrictions” below for additional information.

As a mortgage guaranty insurer, we are eligible for a tax deduction, subject to certain limitations, related to amounts required to be set aside in statutory contingency reserves to the extent we purchase U.S. Mortgage Guaranty Tax and Loss Bonds issued by the U.S. Department of the Treasury. Under SAP, this deduction reduces the tax provision reflected in the statutory financial statements, which in turn increases statutory net income and surplus as well as Available Assets under the PMIERs. As of December 31, 2023, Radian Guaranty held $750 million of these bonds, which have a 10-year original maturity but may generally be redeemed in any tax year prior to maturity.

Our insurance subsidiaries’ statutory net income (loss) for the periods indicated, and statutory policyholders’ surplus as of the dates indicated, were as follows.

Radian Title Insurance	41,108		39,285		36,599

(1)See the “Surplus additions (distributions)” table under “Statutory Dividend Restrictions” below for additional information on certain changes impacting policyholders’ surplus.

Statutory Capital Requirements

Under state insurance regulations, Radian Guaranty is required to maintain minimum surplus levels and, in certain states, a maximum ratio of net RIF relative to statutory capital, or Risk-to-capital. The most common Statutory RBC Requirement is that a mortgage insurer’s Risk-to-capital may not exceed 25 to 1. In certain of the RBC States, a mortgage insurer must satisfy an MPP Requirement. Unless an RBC State grants a waiver or other form of relief, if a mortgage insurer, such as Radian Guaranty, is not in compliance with the Statutory RBC Requirement of that state, the mortgage insurer may be prohibited from writing new mortgage insurance business in that state.

The statutory capital requirements for the non-RBC States are de minimis (ranging from $1 million to $5 million); however, the insurance laws of these states generally grant broad supervisory powers to state agencies or officials to enforce rules or exercise discretion affecting almost every significant aspect of the insurance business, including the power to revoke or restrict an insurance company’s ability to write new business. Radian Guaranty’s domiciliary state, Pennsylvania, is not one of the RBC States.

Radian Guaranty was in compliance with all applicable Statutory RBC Requirements and MPP Requirements in each of the RBC States as of December 31, 2023. Radian Guaranty’s Risk-to-capital was 10.4:1 and 10.7:1 as of December 31, 2023 and 2022, respectively. For purposes of the Risk-to-capital requirements imposed by certain states, statutory capital is defined as the sum of statutory policyholders’ surplus and statutory contingency reserves. Our other mortgage insurance and title insurance subsidiaries were also in compliance with all statutory and counterparty capital requirements as of December 31, 2023 and 2022.

During the past 10 years, the NAIC has been considering changes to the Model Act and has been reviewing the minimum capital and surplus requirements for mortgage insurers to develop a new capital standard for mortgage guaranty insurers and to “strengthen and modernize” the Mortgage Guaranty Insurance Model Act. In 2021, the NAIC developed a new, legally non-binding capital monitoring framework that regulators could use as an alternative for assessing the capital adequacy of a mortgage insurer and added a new mortgage guaranty supplemental filing for companies to annually report related information. This monitoring framework, which is separate from the Model Act, is intended to be reactive to, among other things, changes in the economic and housing environment, including changes in home prices and incomes. In August 2023, the NAIC adopted amendments that revise the Model Act, including with respect to capital and reserve requirements, reinsurance, underwriting practices, quality assurance, and policy form and rate filings. The requirements with respect to minimum capital and surplus requirements for mortgage insurers were not materially changed in the Model Act, as amended. The potential impact on the Company is not expected to be material and will depend on which states, if any, ultimately adopt the amended Model Act.

PMIERs

The PMIERs financial requirements require that a mortgage insurer’s Available Assets meet or exceed its Minimum Required Assets. At December 31, 2023, Radian Guaranty is an approved mortgage insurer under the PMIERs and is in compliance with the current PMIERs financial requirements.

The GSEs may amend the PMIERs at any time, and they have broad discretion to interpret the requirements; any amendments or changes in interpretation could impact the calculation of Radian Guaranty’s Available Assets and/or Minimum Required Assets. In addition, the GSEs have a broad range of consent rights under the PMIERs and require private mortgage insurers to obtain the prior consent of the GSEs before taking certain actions. If Radian Guaranty is unable to satisfy the requirements set forth in the PMIERs, the GSEs could restrict it from conducting certain types of business with them or take actions that may include not purchasing loans insured by Radian Guaranty.

Statutory Dividend Restrictions

As of December 31, 2023, the amount of restricted net assets held by our consolidated insurance subsidiaries (which represents our equity investment in those insurance subsidiaries) totaled $4.6 billion of our consolidated net assets. Despite holding assets above the minimum statutory capital thresholds and PMIERs financial requirements, the ability of Radian’s mortgage insurance subsidiaries to pay dividends on their common stock has been restricted by certain provisions of the insurance laws of Pennsylvania, their state of domicile.

Under Pennsylvania’s insurance laws, ordinary dividends and distributions may only be paid out of an insurer’s positive unassigned surplus unless the Pennsylvania Insurance Department approves the payment of extraordinary dividends or other distributions from another source. While all proposed dividends and distributions to stockholders must be filed with the Pennsylvania Insurance Department prior to payment, if a Pennsylvania domiciled insurer has positive unassigned surplus, such insurer can pay dividends or other distributions during any 12-month period in an aggregate amount less than or equal to the greater of: (i) 10% of the preceding year-end statutory policyholders’ surplus or (ii) the preceding year’s statutory net income, in each case without the prior approval of the Pennsylvania Insurance Department.

Aided by the positive impacts of the merger with Radian Reinsurance in December 2022, Radian Guaranty had positive unassigned surplus of $258 million as of December 31, 2022, and continued to maintain positive unassigned surplus throughout 2023. As a result, beginning with the first quarter of 2023, Radian Guaranty had the ability to pay ordinary dividends, and paid total ordinary dividends of $400 million in cash and marketable securities in 2023. As of December 31, 2023, Radian Guaranty had positive unassigned surplus of $120 million. Subsequent to year end, in February 2024, Radian Guaranty paid an ordinary dividend of $100 million in cash and marketable securities to Radian Group.

As of December 31, 2023 and 2022, Radian Guaranty had contingency reserves of $5.0 billion and $4.4 billion, respectively. As discussed above, Radian Guaranty is scheduled to release contingency reserves to unassigned surplus in material amounts beginning in 2024, which should enhance Radian Guaranty’s ability to maintain a positive unassigned surplus position and to continue to pay ordinary dividends to Radian Group in future periods.

The surplus additions (distributions) between Radian Group and Radian Guaranty and our other insurance subsidiaries for the years ended December 31, 2023, 2022 and 2021, were as follows.

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation and Other Benefit Programs

Share-Based Compensation and Other Benefit Programs

Our most recent Equity Plan is The Radian Group 2021 Equity Plan (the “2021 Equity Plan”), which was approved by our stockholders and applies to awards granted on or after May 12, 2021, the effective date of the plan (the “Effective Date”). In addition to the 2021 Equity Plan, we also have granted awards that remain outstanding under prior plans approved by our stockholders and adopted in each of 1995, 2008, 2014 and 2017 (collectively, the “Prior Equity Plans” and, together with the 2021 Equity Plan, the “Equity Plans”).

The 2021 Equity Plan authorizes the issuance of up to 8.3 million new shares of our common stock, plus: (i) any shares of our common stock that remained available for awards under the plan adopted in 2017 as of the Effective Date and (ii) any shares of our common stock subject to outstanding awards under the Prior Equity Plans as of the Effective Date that are payable in shares and that terminate, expire, or are canceled without having been exercised, vested, or settled in full (as applicable) on or after the Effective Date, subject to certain adjustments set forth in the 2021 Equity Plan (“Prior Plans Shares”). There were 5.3 million shares available for grant under the 2021 Equity Plan, including Prior Plans Shares, as of December 31, 2023.

Outstanding awards granted under the Equity Plans include both performance-based and time-based RSUs, non-qualified stock options and phantom stock. The maximum contractual term for stock options and similar instruments under the Equity Plans is 10 years. To date, all awards granted under the 2021 Equity Plan have been either performance-based or time-based RSUs.

Awards under our plans generally vest over performance or service periods ranging from one to three years, although they may vest earlier under certain circumstances, including in the event of a grantee’s death or disability or, if certain conditions are met, upon retirement, termination or a change of control.

The following table summarizes the compensation cost recognized and additional information regarding all share-based awards for the years indicated.

Share-based compensation expense
	Years Ended December 31,

Share-based compensation expense, net	$	31,695	$	30,537	$	21,195

(1)Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. For purposes of calculating compensation cost recognized for retirement eligible grantees, we consider the service condition to be met (and recognize the full compensation costs) as of the date when a grantee becomes retirement eligible.

As of December 31, 2023, unrecognized compensation expense for all of our outstanding share-based awards was $28.6 million. Absent a change of control under the Equity Plans, this expense is expected to be recognized over a weighted-average period of approximately 1.9 years. The ultimate unrecognized expense associated with our outstanding awards could differ, depending upon whether or not the performance and service conditions are met.

(1)Outstanding RSUs represent shares that have not yet been issued because not all conditions necessary to earn the right to benefit from the instruments have been satisfied. For performance-based awards, the final number of RSUs distributed depends on: (i) the cumulative growth in Radian’s book value per share adjusted for certain defined items over the respective three-year performance period and for the performance-based RSUs granted in 2023 also include a modifier based on a comparison of our total shareholder return to the total shareholder return of certain of our peers and (ii) with the exception of certain retirement-eligible employees, continued service through the vesting date, which could result in changes in the number of vested RSUs.

(2)For performance-based RSUs, amount represents the number of target shares at grant date.

(3)For performance-based RSUs, amount represents the difference between the number of shares vested at settlement, which can range from 0 to 200% of target depending on results over the applicable performance periods, and the number of target shares at the grant date.

(4)Represents amounts vested during the year, including the impact of performance adjustments for performance-based awards.

The weighted-average grant date fair value of performance-based RSUs granted during 2022 and 2021 was $20.09 and $20.39, respectively. The weighted-average grant date fair value of time-vested RSUs granted during 2022 and 2021 was $20.61 and $21.71, respectively.

The fair value as of the respective vesting dates of performance-based RSUs vested during 2023, 2022 and 2021 was $27 million, $17 million and $19 million, respectively. The fair value as of the respective vesting dates of time-vested RSUs vested during 2023, 2022 and 2021 was $16 million, $11 million and $18 million, respectively.

Dividend equivalents are accrued on all awards when dividends are declared on the Company’s common stock and will generally be paid in cash when the awards are settled.

Performance-Based RSUs. For awards granted in 2023, 2022 and 2021, the vesting of the performance-based RSUs is generally over a three-year performance period and will be based primarily upon the cumulative growth in Radian’s book value per share, adjusted for certain defined items, which in 2023 includes our total shareholder return relative to certain peers. The

payout at the end of the three-year performance period generally ranges from 0% to a maximum payout of 200% of the award’s target number of RSUs granted. Performance-based RSUs granted to executive officers are subject to a one-year post-vesting holding period.

The grant date fair value of the performance-based RSUs that are based on the cumulative growth in Radian’s book value per share, as further described above, is calculated based on the stock price as of the grant date, discounted for executive officers to account for the one-year post-vesting holding period. In addition, we adjust the expense recognized on these performance condition awards over the service period to incorporate the probable outcome of achieving the performance measure. For awards that include a total shareholder return market condition in its criteria, we also incorporate a Monte Carlo valuation model at grant date based on multiple input variables, including expected volatilities, correlation coefficients and risk-free interest rates.

Time-Vested RSUs. With the exception of certain time-vested RSUs granted in 2023, 2022 and 2021 to non-employee directors, the time-vested RSU awards granted in 2023, 2022 and 2021 are scheduled to vest in: (i) pro rata installments on a common calendar date that is on or around each of the first three anniversaries of the grant date or (ii) generally at the end of three years. Certain time-vested RSU awards granted in 2023, 2022 and 2021 to non-employee directors generally are subject to one-year cliff vesting; however, awards granted to non-employee directors prior to 2020 remain outstanding and the shares are not issued until the non-employee director retires or certain conditions related to a change in control are met, as described above.

Upon the exercise of stock options, we generally issue shares from the authorized, unissued share reserves when the exercise price is less than the treasury stock repurchase price and from treasury stock when the exercise price is greater than the treasury stock repurchase price.

Generally, the stock option awards had a four-year vesting period, with 50% of the award vesting on or after the third anniversary of the grant date and the remaining 50% of the award vesting on or after the fourth anniversary of the grant date, provided the applicable stock price performance hurdle is met. There have been no stock options granted since 2016.

Employee Stock Purchase Plan

The ESPP is designed to allow eligible employees to purchase shares of our common stock at a discount of 15% off the lower of the fair market value of our common stock at the beginning or end of a six-month offering period (each period being the first and second six months in a calendar year).

Under this plan, we issued approximately 100 thousand shares to employees during each of the years ended December 31, 2023, 2022 and 2021. As of February 2024, approximately 1.4 million shares remain available for issuance under the ESPP.

Benefit Plans

The Radian Group Inc. Savings Incentive Plan (“Savings Plan”) covers substantially all of our full-time and our part-time employees. Participants can contribute up to 100% of their eligible earnings as pretax and/or after-tax (Roth IRA) contributions up to a maximum Internal Revenue Service annual limit, which was $22,500 for 2023. The Savings Plan also includes the catch-up contribution provision whereby participants who are or will be age 50 and above during the Savings Plan year may contribute an additional contribution. The maximum catch-up contribution for the Savings Plan in 2023 was $7,500. We match up to 100% of the first 6% of eligible compensation contributed in any given year. Our expense for matching funds for the years ended December 31, 2023, 2022 and 2021, was $8 million, $10 million and $8 million, respectively.

Schedule II—Financial Information of Registrant
Supplemental Notes

Parent Company Only

Note A

The Radian Group Inc. (the “Parent Company,” “we” or “our”) financial statements represent the stand-alone financial statements of the Parent Company. These financial statements have been prepared on the same basis and using the same accounting policies as described in the consolidated financial statements included herein, except that the Parent Company uses the equity-method of accounting for its majority-owned subsidiaries. These financial statements should be read in conjunction with our consolidated financial statements and the accompanying notes thereto.

See Notes 12 and 14 of Notes to Consolidated Financial Statements for additional information on the Parent Company’s debt obligations and capital stock.

The Parent Company has entered into the following guarantees on behalf of our subsidiaries:

■Beginning in 2022, Radian Group entered into certain Parent Guarantees to support its mortgage conduit business. See Note 12 of Notes to Consolidated Financial Statements for additional information.

■To allow our mortgage insurance customers to comply with applicable securities regulations for issuers of ABS (including mortgage-backed securities), Radian Group has guaranteed two structured transactions for Radian Guaranty with $54 million of aggregate remaining credit exposure as of December 31, 2023.

■Radian Group and Radian Mortgage Assurance are parties to a guaranty agreement, which provides that Radian Group will make sufficient funds available to Radian Mortgage Assurance to ensure that Radian Mortgage Assurance has a minimum of $5 million of statutory policyholders’ surplus every calendar quarter. Radian Mortgage Assurance had $9 million of statutory policyholders’ surplus and no RIF exposure as of December 31, 2023.

As of December 31, 2023, Radian Group recorded a net deferred tax liability of $226 million. This balance includes liabilities related to certain of our subsidiaries, which have incurred federal NOLs that could not be carried-back and utilized on a separate company tax return basis. As a result, we are not currently obligated under our tax-sharing agreement to reimburse these subsidiaries for their separate company federal NOL carryforward. However, if in a future period one of these subsidiaries utilizes its share of federal NOL carryforwards on a separate entity basis, then Radian Group may be obligated to fund such subsidiary’s share of our consolidated tax liability to the Internal Revenue Service.

Note B

The Parent Company provides certain services to its subsidiaries. The Parent Company allocates to its subsidiaries expenses it incurs in the capacity of supporting those subsidiaries, including operating expenses, which are allocated based on the forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on certain subsidiaries, and interest expense, which is allocated based on relative capital. These expenses are presented net of allocations in the Condensed Statements of Operations. Substantially all operating expenses and interest expense have been allocated to the subsidiaries for 2023, 2022 and 2021.

Amounts allocated to the subsidiaries for expenses are based on actual cost, without any mark-up. The Parent Company considers these charges to be fair and reasonable. The subsidiaries generally reimburse the Parent Company for these costs in a timely manner, which has the impact of temporarily improving the cash flows of the Parent Company, if accrued expenses are reimbursed prior to actual payment.

The following table shows the components of our Parent Company expenses that have been allocated to our subsidiaries for the periods indicated.

(In thousands)	2023		2022		2021
Allocated operating expenses	$	163,858	$	163,000	$	147,386

Total allocated expenses	$	246,592	$	245,568	$	230,219

Note C

During 2023 and 2022, certain non-insurance subsidiaries had not generated sufficient cash flow to reimburse the Parent Company for its share of its direct and allocated operating expenses, and therefore the Parent Company effectively contributed a total of $110 million and $82 million, respectively, to these subsidiaries to reflect the impairment of the intercompany receivables representing unreimbursed direct and allocated costs.

See Note 16 of Notes to Consolidated Financial Statements for additional information related to capital transactions between the Parent Company and its consolidated insurance subsidiaries, including $400 million in ordinary dividends paid during 2023 from Radian Guaranty to Radian Group.

Note D

As of December 31, 2023 and 2022, the Parent Company’s other assets related primarily to: (i) its participation in a securities lending program; (ii) intercompany receivables; and (iii) property and equipment. As of December 31, 2023 and 2022, the Parent Company’s other liabilities related primarily to: (i) accounts payable and accrued expenses and (ii) its participation in a securities lending program. See Note 6 of Notes to Consolidated Financial Statements for additional information on this program.

Significant Accounting Policies (Policies)

Dec. 31, 2023

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

Our consolidated financial statements are prepared in accordance with GAAP and include the accounts of Radian Group and its subsidiaries. All intercompany accounts and transactions, and intercompany profits and losses, have been eliminated. Certain prior period amounts have been reclassified to conform to the current period presentation.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of our contingent assets and liabilities at the dates of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. While the amounts included in our consolidated financial statements include our best estimates and assumptions, actual results may vary materially.

Investments

Investments

We group fixed-maturity securities in our investment portfolio into trading or available for sale securities. Trading securities are reported at fair value, with unrealized gains and losses reported as a separate component of income. Investments in fixed-maturity securities classified as available for sale are reported at fair value, with unrealized gains and losses (net of tax) reported as a separate component of stockholders’ equity as accumulated other comprehensive income (loss).

We also invest in several other types of investments including equity securities, which primarily consist of our interests in a variety of broadly diversified exchange traded funds and are recorded at fair value with unrealized gains and losses reported in income. Mortgage loans held for sale consist of residential mortgage loans, which we purchase with the intention of reselling and have elected to measure at fair value with unrealized gains and losses reported in income. Short-term investments are also carried at fair value and consist of money market instruments, certificates of deposit and highly liquid, interest-bearing instruments with an original maturity of 12 months or less at the time of purchase.

Amortization of premium and accretion of discount are calculated principally using the interest method over the term of the investment. Realized gains and losses on investments are recognized using the specific identification method. See Notes 5 and 6 for further discussion on investments.

We recognize an impairment as a loss for fixed-maturities available for sale on the consolidated statements of operations if: (i) we intend to sell the impaired security; (ii) it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis; or (iii) the present value of cash flows we expect to collect is less than the amortized cost basis of a security. In those instances, we record an impairment loss through earnings that varies depending on specific circumstances. If a sale is likely, the full amount of the impairment is recognized as a loss in the consolidated statements of operations. Otherwise, unrealized losses on securities are separated into: (i) the portion of loss that represents the credit loss and (ii) the portion that is due to other factors. In evaluating whether a decline in value for other securities relates to an existing credit loss, we consider several factors, including, but not limited to, the following:

■the extent to which the amortized cost basis is greater than fair value;

■reasons for the decline in value (e.g., adverse conditions related to industry or geographic area, changes in financial condition to the issuers or underlying loan obligors);

■any changes to the rating of the security by a rating agency;

■the failure of the issuer to make a scheduled payment;

■the financial position, access to capital and near-term prospects of the issuer, including the current and future impact of any specific events; and

■our best estimate of the present value of cash flows expected to be collected.

If a credit loss is determined to exist, the impairment amount is calculated as the difference between the amortized cost and the present value of future expected cash flows, limited to the difference between the carrying amount (i.e., fair value) and amortized cost. This credit loss impairment is included in net gains (losses) on investments and other financial instruments in the consolidated statements of operations, with an offset to an allowance for credit losses. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss impairment or a reversal of credit loss impairment.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Our estimated fair value measurements are intended to reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. Changes in economic conditions and capital market conditions, including but not limited to, credit spread changes, benchmark interest rate changes, market volatility and changes in the value of underlying collateral, could cause actual results to differ materially from our estimated fair

value measurements. We define fair value as the current amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

In accordance with GAAP, which establishes a three-level valuation hierarchy, we disclose fair value measurements based on the transparency of inputs to the valuation of an asset or liability as of the measurement date. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurements) and the lowest priority to unobservable inputs (Level III measurements). The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the measurement in its entirety. The three levels of the fair value hierarchy are defined below:

Level I    —    Unadjusted quoted prices for identical assets or liabilities in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level II    —    Prices or valuations based on observable inputs other than quoted prices in active markets for identical assets and liabilities; and

Level III    —    Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Level III inputs are used to measure fair value only to the extent that observable inputs are not available.

For markets in which inputs are not observable or are limited, we use significant judgment and assumptions that a typical market participant would use to evaluate the market price of an asset or liability. Given the level of judgment necessary, another market participant may derive a materially different estimate of fair value. These assets and liabilities are classified in Level III of our fair value hierarchy.

Available for sale securities, trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are recorded at fair value as described in Note 5. All changes in fair value of trading securities, equity securities, mortgage loans held for sale and certain other assets and liabilities are included in our consolidated statements of operations.

Restricted Cash

Restricted Cash

Included in our restricted cash balances as of December 31, 2023 and 2022, were cash funds held in trusts for the benefit of certain counterparties, primarily as security for the payment and performance of the Company’s obligations.

Accounts and Notes Receivable

Accounts and Notes Receivable

Accounts and notes receivable primarily consist of accrued premiums receivable, amounts billed and due from our customers for services performed, and certain receivables related to our reinsurance transactions. Accounts and notes receivable are carried at their estimated collectible amounts, net of any allowance for doubtful accounts, and are periodically evaluated for collectability based on past payment history and current economic conditions. See “Revenue Recognition—Mortgage Insurance” below for information on our deferred premiums and Note 8 for details on our reinsurance agreements.

Income Taxes

Income Taxes

We provide for income taxes in accordance with the provisions of the accounting standard regarding accounting for income taxes. As required under this standard, our deferred tax assets and deferred tax liabilities are recognized under the balance sheet method, which recognizes the future tax effect of temporary differences between the amounts recorded in our consolidated financial statements and the tax bases of these amounts. Deferred tax assets and deferred tax liabilities are measured using the enacted tax rates that are expected to apply to taxable income in the periods in which the deferred tax asset or deferred tax liability is expected to be realized or settled. In regard to accumulated other comprehensive income, the Company’s policy for releasing disproportionate income tax effects is to release the effects as individual items are sold.

We are required to establish a valuation allowance against our deferred tax assets when it is more likely than not that all or some portion of our deferred tax assets will not be realized. At each balance sheet date, we assess our need for a valuation allowance. Our assessment is based on all available evidence, both positive and negative. This requires management to exercise judgment and make assumptions regarding whether our deferred tax assets will be realized in future periods.Our policy for the recognition of interest and penalties associated with uncertain tax positions is to record such items as a component of our income tax provision, of which $776 thousand of expense and $182 thousand of benefit were recorded for the years ended December 31, 2023 and 2022, respectively.

Reserve for Losses and LAE

Reserve for Losses and LAE

Mortgage Insurance

We establish reserves to provide for losses and LAE on our mortgage insurance policies, which include the estimated costs of settling claims, in accordance with the accounting standard regarding accounting and reporting by insurance enterprises (ASC 944). Although this standard specifically excludes mortgage insurance from its guidance relating to the

reserve for losses, because there is no specific guidance for mortgage insurance, we establish reserves for mortgage insurance as described below, using the guidance contained in this standard supplemented with other accounting guidance.

In our mortgage insurance business, the default and claim cycle begins with the receipt of a default notice from the loan servicer. Case reserves for losses are established upon receipt of notification from servicers that a borrower has missed two monthly payments, which is when we consider a loan to be in default for financial statement and internal tracking purposes. We also establish reserves for associated LAE, consisting of the estimated cost of the claims administration process, including legal and other fees and expenses associated with administering the claims process.

We do not establish reserves for loans that are in default if we believe that we will not be liable for the payment of a claim with respect to that default. We generally do not establish loss reserves for expected future claims on insured mortgages that are not in default. See “Reserve for Premium Deficiency” below for an exception to these general principles.

With respect to loans that are in default, considerable judgment is exercised as to the adequacy of reserve levels. We use an actuarial projection methodology referred to as a “roll rate” analysis that uses historical claim frequency information to determine the projected ultimate Default to Claim Rates based on the Stage of Default and Time in Default as well as the date that a loan goes into default. The Default to Claim Rate also includes our estimates with respect to expected Loss Mitigation Activities, which have the effect of reducing our Default to Claim Rates.

After estimating the Default to Claim Rate, we estimate Claim Severity based on observed severity rates within product type, type of insurance and Time in Default cohorts. These severity estimates are then applied to individual loan coverage amounts to determine reserves.

Rescissions, Claim Denials and Claim Curtailments may occur for various reasons, including, without limitation, underwriting negligence, fraudulent applications and appraisals, breach of representations and warranties and inadequate documentation, primarily related to our insurance written in years prior to and including 2008. For our Loss Mitigation Activities, we incorporate a process referred to as a claims rebuttal process by which the insured or servicer of loans may challenge our decisions. Our estimate of future Loss Mitigation Activities incorporates our estimates of the likely outcomes of our claims rebuttal process based on historical practices.

Estimating our case reserve for losses involves significant reliance upon assumptions and estimates with regard to the likelihood, magnitude and timing of each potential loss. The models, assumptions and estimates we use to establish loss reserves may not prove to be accurate, especially in the event of an extended economic downturn or a period of market volatility and economic uncertainty. These assumptions require management to use considerable judgment in estimating the rate at which these loans will result in claims and the amount of claims we expect to pay. As such, there is uncertainty around our reserve estimate.

Title Insurance

We establish reserves for estimated future claims payments on our title insurance policies at the time the related policy revenue is recorded. Our title insurance reserve for losses and LAE comprises estimates of both known claims and incurred but unreported claims expected to be paid in the future for policies issued as of the balance sheet date.

We provide for losses associated with these policies based upon our historical experience and other factors. However, by their nature, title claims can often be complex, vary greatly in dollar amounts, vary in number due to economic and market conditions such as an increase in mortgage foreclosures, and involve uncertainties as to ultimate exposure. Due to the length of time over which claim payments are made and regularly occurring changes in underlying economic and market conditions, these estimates are subject to variability.

Reserve for Premium Deficiency

Reserve for Premium Deficiency

Insurance enterprises are required to establish a premium deficiency reserve if the net present value of the expected future losses and expenses for a particular product line exceeds the net present value of expected future premiums and existing reserves for that product line. We reassess our expectations for premiums, losses and expenses for our mortgage insurance business at least quarterly and update our premium deficiency analyses accordingly. For our mortgage insurance business, we group our mortgage insurance products into two categories: first-lien and second-lien mortgage loans.

We did not require a first-lien or second-lien premium deficiency reserve as of December 31, 2023 or 2022.

Revenue Recognition

Revenue Recognition

Mortgage Insurance

Premiums on mortgage insurance products are written on a recurring basis, either as monthly or annual premiums, or on a multi-year basis as a single premium. Monthly premiums written are earned as coverage is provided each month. For certain monthly policies where the billing is deferred for the first month’s coverage period, currently to the end of the policy, we record a net premium receivable representing the present value of such deferred premiums that we estimate will be collected at that

future date. As of December 31, 2023 and 2022, this net premium receivable was $36 million and $32 million, respectively, representing the present values of $81 million and $77 million, respectively, in contractual deferred monthly premiums, after adjustments for the estimated collectability and timing of future billing. We recognize changes in this receivable based on changes in the estimated amount and timing of such collections, including as a result of changes in observed trends as well as our periodic review of our servicing guide and our operations and collections practices. Given the difference between the present value of the net premium receivable recorded and the contractual premiums due, such changes to the preceding factors could have a material effect on our results of operations in future periods if any changes are implemented.

Annual premiums written are initially recorded as unearned premiums and amortized on a monthly, straight-line basis. Single premiums written are initially recorded as unearned premiums and earned over time based on the anticipated claim payment pattern, which includes historical industry experience and is updated periodically.

When we rescind insurance coverage on a loan, we refund all premiums received in connection with such coverage. When insurance coverage on a loan is canceled due to claim payment, we refund all premiums received since the date of delinquency. When insurance coverage is canceled for a reason other than Rescission or claim payment, all premium that is nonrefundable is immediately earned. Premium revenue is recognized net of our accrual for estimated premium refunds due to Rescissions, claim payments or other factors.

With respect to our reinsurance transactions, ceded premiums written on an annual or multi-year basis are initially set up as prepaid reinsurance and are amortized in a manner consistent with the recognition of income on direct premiums.

Title Insurance and Related Services

Title insurance premiums are recognized as revenue upon closing and completion of the real estate transaction. Premiums generally are calculated with reference to the policy amount. Premiums are charged to customers based on rates predetermined in coordination with each state’s respective Department of Insurance. Such regulations vary from state to state. Premium revenues from agency title operations are primarily comprised of premiums recognized upon title order and completion of real estate transaction closing.

Other title-related fees and income are closely related to title insurance premiums and are primarily associated with managing the closing of real estate transactions. As such, revenue is primarily recognized upon closing of the real estate transaction or completion and billing of services. We offer title services that include tax and title data services; centralized recording services; document retrieval; default curative title services; deed reports; property reports and other real estate or title-related activities. Expenses typically associated with premiums include third-party agent commissions and premium taxes

Other Services

Other Products and Services

We recognize revenue representing the transfer of services to customers in an amount that reflects the consideration that we expect to be entitled to receive in exchange for those services, which are recognized as the performance obligations are satisfied. Due to the transactional nature of our business, our services revenue may fluctuate from period to period as transactions are commenced or completed.

Our services and related revenue recognition considerations are primarily as follows:

Real Estate. We provide real estate services, including asset management and valuation services. Asset management services include management of the entire REO disposition process and services such as diligence and underwriting that serve the single-family rental asset class. In certain instances, fees are received at the time that an asset is assigned to Radian for management. These fees are recorded as deferred revenue and are recognized over time based on progress to date and the availability to customers. In addition, we offer a web-based asset management workflow solution to assist in managing REO assets, rental properties, due diligence for bulk acquisitions of multiple properties, loss mitigation efforts and short sales.

For valuation services, we leverage technology and a quality control process to deliver real estate valuation products and services to our customers, which include: appraisal review products; hybrid/ancillary appraisal products; automated valuation products; interactive valuation products; and broker price opinions. Each service qualifies as a separate performance obligation for which revenue is recognized as the service is performed and made available to the client.

Real Estate Technology. We are continuing to develop a growing suite of real estate technology products and services that are designed to facilitate real estate transactions and are provided as proprietary platform-as-a-service solutions. Revenues for these services are recognized over time as the service is provided and made available to the customer.

Mortgage Services. We provide third-party contract underwriting solutions to our mortgage customers. Generally, revenue is recognized when contract underwriting results are made available to the customer or when other related services are completed.

Cost of Services

Cost of Services

Cost of services consists primarily of costs paid for employee compensation and related payroll benefits, as well as corresponding travel and related expenses, incurred in providing such services to clients.

Leases

Leases

We determine if an arrangement includes a lease at inception, and if it does, we recognize a right-of-use asset and lease liability. Right-of-use assets represent our right to use an underlying asset for the lease term and are recognized net of any payments made or received from the lessor. Lease liabilities represent our obligation to make lease payments and are based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date.

Lease expense is recognized on a straight-line basis over the expected lease term. Lease and non-lease components are generally not accounted for separately.

Our lease agreements primarily relate to operating leases for office space we use in our operations. Certain of our leases include renewal options and/or termination options that we did not consider in the determination of the right-of-use asset or the lease liability as we did not believe it was reasonably certain that we would exercise such options.

We assess our various asset groups, which include right-of-use assets, for changes in grouping and for potential impairment when certain events occur or when there are changes in circumstances, including potential alternative uses. If circumstances require a change in asset groupings or a right-of-use asset to be tested for possible impairment, and the carrying value of the right-of-use asset is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value.

Reinsurance

Reinsurance

We cede insurance risk through the use of reinsurance contracts and follow reinsurance accounting for those transactions where significant risk is transferred. Loss reserves and unearned premiums are established before consideration is given to amounts related to our reinsurance agreements.

In accordance with the terms of the QSR Program, rather than making a cash payment or transferring investments for ceded premiums written, Radian Guaranty holds the related amounts to collateralize the reinsurers’ obligations and has established a corresponding funds withheld liability. Any loss recoveries and any potential profit commission to Radian Guaranty will be realized from this account. The reinsurers’ share of earned premiums is paid from this account on a quarterly basis. For our Single Premium QSR Program, this liability also includes an interest credit on funds withheld, which is recorded as ceded premiums at a rate specified in the agreement and, depending on experience under the contract, may be paid to either Radian Guaranty or the reinsurers.

The ceding commission earned for premiums ceded pursuant to this transaction is attributable to other underwriting costs (including any related deferred policy acquisition costs). The unamortized portion of the ceding commission in excess of our related acquisition cost is reflected in other liabilities. Ceded premiums written are recorded on the balance sheet as prepaid reinsurance premiums and amortized to ceded premiums earned in a manner consistent with the recognition of income on direct premiums.

Variable Interest Entities

Variable Interest Entities

In connection with our reinsurance programs for our mortgage insurance business, we may enter into contracts with VIEs. VIEs include corporations, trusts or partnerships in which: (i) the entity has insufficient equity at risk to allow it to finance its activities without additional subordinated financial support or (ii) at-risk equity holders, as a group, do not have the characteristics of a controlling financial interest.

We perform an evaluation to determine whether we are required to consolidate the VIE’s assets and liabilities in our consolidated financial statements, based on whether we are deemed to be the primary beneficiary. The primary beneficiary of a VIE is the variable interest holder that is determined to have the controlling financial interest as a result of having both: (i) the power to direct the activities of a VIE that most significantly impact the economic performance of the VIE and (ii) the obligation to absorb losses or right to receive benefits from the VIE that potentially could be significant to the VIE.

Goodwill and Other Acquired Intangible Assets, Net

Goodwill and Other Acquired Intangible Assets, Net

Goodwill is an asset representing the estimated future economic benefits arising from the assets we have acquired that were not individually identified and separately recognized. Goodwill is deemed to have an indefinite useful life and is subject to review for impairment annually, or more frequently whenever circumstances indicate potential impairment at the reporting unit

level. A reporting unit represents a business for which discrete financial information is available. We have concluded that we have one reporting unit, our homegenius segment, for purposes of our goodwill impairment assessment. We generally perform our annual goodwill impairment test during the fourth quarter of each year, comparing the carrying value of the reporting unit as of the prior quarter to its estimated fair value. An impairment charge is recognized for any excess of the reporting unit’s carrying amount over the reporting unit’s estimated fair value, up to the full amount of the goodwill allocated to the reporting unit.

Property and Equipment

Property and Equipment

We capitalize certain costs associated with the development of internal-use software and the purchase of property and equipment. Software, property and equipment are carried at cost, net of accumulated depreciation and amortization. Amortization and depreciation are calculated on a straight-line basis over the estimated useful life of the respective assets and commence during the month of our placement of the assets into use.

The estimated useful life used to calculate the amortization of internal-use software is generally seven years. Leasehold improvements are depreciated over the lesser of the estimated useful life of the asset improved or the remaining term of the lease. The estimated useful life used to calculate the depreciation of furniture and equipment is generally three years.

Deferred Policy Acquisition Costs

Deferred Policy Acquisition Costs

Incremental, direct costs associated with the successful acquisition of mortgage insurance policies, consisting of compensation, premium tax and other policy issuance and underwriting expenses, are initially deferred and reported as deferred policy acquisition costs. Consistent with industry accounting practice, amortization of these costs for each underwriting year book of business is recognized in proportion to estimated gross profits over the estimated life of the policies.

Estimated gross profits are composed of earned premium, interest income, losses and LAE. Estimates of expected gross profit, including the Persistency Rate and loss development assumptions for each underwriting year used as a basis for amortization, are evaluated quarterly and the total amortization recorded to date is adjusted by a charge or credit to our consolidated statements of operations if actual experience or other evidence suggests that previous estimates should be revised. Considerable judgment is used in evaluating these estimates and the assumptions on which they are based. The use of different assumptions may have a significant effect on the amortization of deferred policy acquisition costs.

Ceding commissions received under our reinsurance arrangements related to these costs are also deferred and accounted for using similar assumptions.

Earnings Per Share

Earnings Per Share

Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding, while diluted net income per share is computed by dividing net income attributable to common stockholders by the sum of the weighted-average number of common shares outstanding and the weighted-average number of dilutive potential common shares.

Dilutive potential common shares relate primarily to our share-based compensation arrangements. In computing diluted net income per share, we use the treasury stock method, which is computed by assuming the issuance of common stock for the potential dilution of our unvested RSUs. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income.

Share-Based Compensation

Share-Based Compensation

The cost related to share-based equity instruments is measured based on the grant-date fair value at the date of issuance, which for RSU awards is primarily determined by our common stock price on the date of grant. For share-based awards with performance conditions related to our own operations, the expense recognized is dependent on the probability of the performance measure being achieved. Compensation cost is generally recognized over the periods that an employee provides service in exchange for the award. Any forfeitures of awards are recognized as they occur.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Accounting Standards Adopted During 2023

In August 2018, the FASB issued ASU 2018-12, Financial Services—Insurance—Targeted Improvements to the Accounting for Long-Duration Contracts. The new standard: (i) requires that assumptions used to measure the liability for future policy benefits be reviewed at least annually; (ii) defines and simplifies the measurement of market risk benefits; (iii) simplifies the amortization of deferred acquisition costs; and (iv) enhances the required disclosures about long-duration

contracts. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The adoption of this update on January 1, 2023, did not have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform—Facilitation of the Effects of Reference Reform on Financial Reporting. This guidance provides optional expedients and exceptions for applying GAAP requirements to investments, derivatives or other transactions affected by reference rate reform such as those that impact the assessment of contract modifications. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform—Deferral of the Sunset Date of Topic 848, which extends the period of time that preparers can utilize the reference rate reform relief guidance. The prospective adoption of this update on July 1, 2023, did not have a material impact on our consolidated financial statements or disclosures.

Accounting Standards Not Yet Adopted

In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements—Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The amendments in this update modify disclosure and presentation requirements related to various topics and align codification with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. If by June 30, 2027, the SEC has not removed the applicable requirements, the pending content will be removed and not become effective. Early adoption is prohibited. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting—Improvements to Reportable Segment Disclosures. This update enhances disclosure requirements, primarily through enhanced disclosures about significant reportable segment expenses under ASC 280. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2023, and interim periods within fiscal periods commencing after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied retrospectively for all periods presented in the financial statements. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

In December 2023, the FASB issued ASU 2023-09, Income Taxes—Improvements to Income Tax Disclosures, an update which enhances income tax disclosures. This guidance requires disaggregated information about an entity’s effective tax rate reconciliation as well as information on income taxes paid. This update is applicable to all public entities and is effective for fiscal years starting after December 15, 2024. Early adoption is permitted. The amendments in this update should be applied prospectively; however, retrospective application is permitted. We are currently evaluating the impact the new accounting guidance will have on our financial statements and disclosures.

Commitments and Contingencies

In the course of our regular review of pending legal actions and proceedings, we determine whether it is reasonably possible that a potential loss may have a material impact on our liquidity, results of operations or financial condition. If we determine such a loss is reasonably possible, we disclose information relating to such potential loss, including an estimate or range of loss or a statement that such an estimate cannot be made. On a quarterly basis, we review relevant information with respect to loss contingencies and update our accruals, disclosures and estimates of reasonably possible losses or range of losses based on such reviews. We are often unable to estimate the possible loss or range of loss until developments in such matters have provided sufficient information to support an assessment of the range of possible loss, such as quantification of a damage demand from plaintiffs, discovery from other parties and investigation of factual allegations, rulings by the court on motions or appeals, analysis by experts and the progress of settlement negotiations. In addition, we generally make no disclosures for loss contingencies that are determined to be remote. For matters for which we disclose an estimated loss, the disclosed estimate reflects the reasonably possible loss or range of loss in excess of the amount accrued, if any.

(1)Represents reserves as of December 31, 2023, related to IBNR liabilities.

(2)Represents total number of new primary default notices received in each calendar year as compiled monthly based on reports received from loan servicers. As reflected in our Default to Claim Rate assumptions, a significant portion of reported defaults generally do not result in a claim. In certain instances, a defaulted loan may cure, and then re-default in a later period. Consistent with our reserving practice, each new event of default is treated as a unique occurrence and therefore certain loans that cure and re-default may be included as a reported default in multiple periods.

(1)Outstanding RSUs represent shares that have not yet been issued because not all conditions necessary to earn the right to benefit from the instruments have been satisfied. For performance-based awards, the final number of RSUs distributed depends on: (i) the cumulative growth in Radian’s book value per share adjusted for certain defined items over the respective three-year performance period and for the performance-based RSUs granted in 2023 also include a modifier based on a comparison of our total shareholder return to the total shareholder return of certain of our peers and (ii) with the exception of certain retirement-eligible employees, continued service through the vesting date, which could result in changes in the number of vested RSUs.

(2)For performance-based RSUs, amount represents the number of target shares at grant date.

(3)For performance-based RSUs, amount represents the difference between the number of shares vested at settlement, which can range from 0 to 200% of target depending on results over the applicable performance periods, and the number of target shares at the grant date.
