Notes to the Condensed Consolidated Financial Statements

Note 1. Business and Basis of Presentation

In July 2020, Trean Insurance Group, Inc. (together with its wholly owned subsidiaries, the "Company") completed its initial public offering ("IPO") of common stock. Prior to the completion of the IPO, the Company effected the following reorganization transactions: (i) each of Trean Holdings LLC ("Trean"), an insurance services company, and BIC Holdings LLC ("BIC"), a property and casualty insurance holding company, contributed all of their respective assets and liabilities to Trean Insurance Group, Inc., a newly formed direct subsidiary of BIC, in exchange for shares of common stock in Trean Insurance Group, Inc. and (ii) upon the completion of the transfers by Trean and BIC, Trean and BIC were dissolved and distributed in-kind common shares to the pre-IPO unitholders.

The Company provides products and services to the specialty insurance market. Historically, the Company has focused on specialty casualty markets that are believed to be under-served and where the Company’s expertise allows the Company to achieve higher rates, such as niche workers' compensation markets and small- to medium-sized specialty casualty insurance programs. The Company underwrites specialty-casualty insurance products both through programs where the Company partners with other organizations ("Program Partners"), and also through the Company’s own managing general agencies ("Owned MGAs"). The Company also provides Program Partners with a variety of services, including issuing carrier services, claims administration, and reinsurance brokerage from which the Company generates fee-based revenues.

The Company's wholly owned subsidiaries include: (a) Benchmark Holding Company, a property and casualty insurance holding company, which owns Benchmark Insurance Company ("Benchmark"), a property and casualty insurance company domiciled in the state of Kansas, American Liberty Insurance Company ("ALIC"), a property and casualty insurance company domiciled in the state of Utah, and 7710 Insurance Company, a property and casualty insurance company domiciled in the state of South Carolina; (b) Trean Compstar Holdings, LLC, a limited liability company created originally for the purchase of Compstar Insurance Services LLC, a California-based general agency; and (c) Trean Corporation ("Trean Corp"), a reinsurance intermediary manager and a managing general agent, which consists of the following wholly owned subsidiaries: Trean Reinsurance Services, LLC, a reinsurance intermediary broker; Benchmark Administrators LLC, a claims third-party administrator; Western Integrated Care, LLC, a managed care organization; and Westcap Insurance Services, LLC, a managing general agent based in California.

The accompanying condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Quarterly Report on Form 10-Q under the Securities Exchange Act of 1934. Accordingly, they do not contain all of the information included in the Company's annual consolidated financial statements and notes. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) necessary for a fair presentation of the Company’s condensed consolidated financial position and results of operations for the periods presented have been included. Although management believes the disclosures and information presented are adequate, these interim condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020 (the "2020 Form 10-K"). Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

During the second quarter of 2021, the Company determined that its funds held agreements with reinsurers contain embedded derivatives relating to a total return swap on the underlying investments. As a result, the Company has revised the presentation of its financial results to report the change in fair value of the embedded derivatives in gains (losses) on embedded derivatives in the condensed consolidated and combined statements of operations. In addition, investment earnings credited to the funds withheld accounts are reported in gains (losses) on embedded derivatives in the condensed consolidated and combined statements of operations, whereas previously these were reported as an offset to net investment income. While the prior period amounts have been corrected for comparability, the correction was not material to the previously reported condensed consolidated and condensed combined financial statements. The impact of the prior period corrections on the condensed consolidated balance sheet and the related components of stockholders' equity is as follows:

The correction of the prior period amounts had no impact on total operating, investing, and financing activities as presented on the Company’s condensed consolidated statements of cash flows during the nine months ended September 30, 2020. In conjunction with the correction of the prior period amounts, the fair value leveling table as of December 31, 2020 in Note 3 was corrected from $174,704, which represented the total funds withheld under reinsurance agreements liability, to $4,937, which relates only to the fair value of the embedded derivative; the net investment income table in Note 4 was corrected to incorporate the income from funds held investments of $507 and $2,481 for the three and nine months ended September 30, 2020, respectively; the effective tax rate in Note 8 was corrected from 1.1% to 1.2% for the three months ended September 30, 2020 and from 5.5% to 4.9% for the nine months ended September 30, 2020; and Note 14 has been corrected to reflect the changes to other comprehensive income described above.

Use of estimates

While preparing the condensed consolidated financial statements, the Company has made certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements, as well as reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Reported amounts that require extensive use of estimates include the reserves for unpaid losses and loss adjustment expenses ("LAE"), reinsurance recoveries, investments, goodwill and other intangible assets. Except for the captions on the condensed consolidated balance sheets and condensed consolidated statements of comprehensive income, generally, the term loss(es) is used to collectively refer to both loss and LAE.

Accounting pronouncements

Recently adopted policies

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). This update provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This standard is effective for

Table of Contents

the period between March 12, 2020 and December 31, 2022. The adoption of this standard did not have a material impact on the condensed consolidated financial statements.

Pending policies

The Company completed its IPO in July 2020, and is an emerging growth company as defined under federal securities laws. As such, the Company has elected to adopt pending accounting policies under the dates required for private companies. Therefore, the dates included within this section reflect the effective dates for the adoption of new accounting policies required by private companies.

In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments (ASU 2020-03). This update represents changes to clarify and improve the codification to allow for easier application by eliminating inconsistencies and providing clarification on items such as (i) the application of fair value option disclosures; (ii) the accounting for fees related to modifications of debt; and (iii) aligning the contractual term of a net investment in a lease in accordance with ASC Topic 326, Financial Instruments - Credit Losses, and the lease term determined in accordance with ASC Topic 842, Leases. The Company adopted items (i) and (ii) effective January 1, 2020 and will adopt item (iii) on January 1, 2023. Adoption of this standard has not had, and is not expected to have, a material impact on the condensed consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivative and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323 and Topic 815 (ASU 2020-01). This update addresses the accounting for certain equity securities upon the application or discontinuation of the equity method of accounting. Further, the update addresses scope considerations for forward contracts and purchased options on certain securities. ASU 2020-01 is effective for annual periods beginning after December 15, 2021, including interim periods thereafter. The Company will adopt this standard effective January 1, 2022. Adoption of this standard is not expected to have a material impact on the condensed consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (ASU 2016-13). This update requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. Additionally, credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses, with the amount of the allowance limited to the amount by which the fair value is below the amortized cost. ASU 2016-13 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. The Company will adopt this standard effective January 1, 2023. The Company is currently evaluating the impact of this standard on the condensed consolidated financial statements.

Note 3. Fair Value Measurements

The Company’s financial instruments include assets and liabilities carried at fair value. The inputs to valuation techniques used to measure fair value are prioritized into a three level hierarchy. The fair value hierarchy is as follows:

Level 1: Fair values primarily based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2: Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.

Level 3: Fair values primarily based on valuations derived when one or more of the significant inputs are unobservable. With little or no observable market, the determination of fair value uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability.

The Company classifies the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. The following tables present the estimated fair value of the Company’s significant financial instruments.

Bonds and equity securities: The Company, in conjunction with its third-party pricing service provider, uses a variety of sources to estimate the fair value of investments such as Reuters, Iboxx, PricingDirect, ICE BofAML Index, ICE Data Services, and for equities, Bloomberg. Equity securities are valued at the closing price on the exchange on which they are primarily traded as provided by a third-party pricing service. Fixed income securities are generally valued at an evaluated bid as provided by a third-party pricing service. Securities and other assets generally valued using third-party pricing services may also be valued at broker/dealer bid quotations. Values obtained from third-party pricing services can utilize several data sources for inputs such as transaction data, yield, quality, coupon rate, maturity, issue type, trading characteristics, and market activity. To validate the reasonableness of the quoted prices, the Company performs various qualitative and quantitative procedures such as analysis of recent trading activity, analytical review of fair values, and an evaluation of the underlying pricing methodologies. Based on these procedures, the Company did not adjust the prices or quotes from the third-party pricing service.

Embedded derivatives: The Company enters into funds held contracts under reinsurance agreements which create embedded derivatives on the underlying investments. These embedded derivatives are valued based upon the unrealized gain or loss position of the funds held portfolio, which is determined consistent with other investments using third-party pricing services. To validate the reasonableness of the quoted prices, the Company performs various qualitative and quantitative procedures such as analysis of recent activity, analytical review of fair values and an evaluation of the underlying pricing methodologies. Based on these procedures, the Company did not adjust the prices or quotes from the third-party pricing service.

Debt: The Company holds debt related to its secured credit facility. The Company has determined that the remaining balance of the debt reflected its fair value as this would represent the total amount to repay the debt.

Note 5. Equity Method Investments

The Company held equity method investments in Compstar and Trean Intermediaries ("TRI"). Equity earnings and losses were reported in equity earnings in affiliates, net of tax on the condensed consolidated statements of operations.

On July 15, 2020, the Company purchased the remaining 55% ownership interest in Compstar and, as a result, Compstar is no longer recorded as an equity method investment. For the three and nine months ended September 30, 2020, the Company recorded earnings of $401 and $2,333, respectively, and received distributions of $540 and $2,842, respectively.

On January 3, 2020, the Company sold 15% of its previous 25% ownership in TRI for cash proceeds of $3,000 resulting in a remaining ownership interest of 10%. As a result of its significant ownership reduction and its lack of significant influence over the operations and policies of TRI, the Company reclassified its TRI investment, at fair value, to investments in common stock in the first quarter of 2020. The Company realized a gain on the sale of $3,115, which is included in net realized capital gains on the condensed consolidated statements of operations. The Company subsequently re-measured its TRI investment shares, resulting in an unrealized gain of $2,000, which is recorded in net investment income on the condensed consolidated statement of operations. The Company received distributions of $225 for the nine months ended September 30, 2020. The Company sold all of its remaining ownership interest in TRI during Q3 2021 for $1,888, resulting in a realized loss of $112, which is included in net realized capital gains on the condensed consolidated statement of operations.

In April 2018, Trean Corp entered into a credit agreement with a bank which includes a term loan facility totaling $27,500 and a revolving credit facility of $3,000. Borrowings are secured by substantially all of the assets of Trean and its subsidiaries.

On May 26, 2020, the Company entered into a new Amended and Restated Credit Agreement which, among other things, extended the Company's credit facility for a period of five years through May 26, 2025 and increased its term loan facility by $11,707, resulting in a total term loan debt amount of $33,000 at the time of closing. The loan has a variable interest rate of LIBOR plus 4.50%, which was 4.65% and 4.72% as of September 30, 2021 and December 31, 2020, respectively. The

outstanding principal balance of the loan is to be repaid in quarterly installments which escalate from $206 to $825. All equity securities of the subsidiaries of Trean Insurance Group, Inc. (other than Benchmark Holding Company and its subsidiaries) have been pledged as collateral.

The Company recorded $377 and $403 of interest expense with its credit facility during the three months ended September 30, 2021 and 2020, respectively. During the nine months ended September 30, 2021 and 2020, the Company recorded $1,145 and $1,125 of interest expense, respectively, associated with its credit facility.

The terms of the credit facility require the Company to maintain certain financial covenants and ratios. The Company was in compliance with all covenants and ratios as of September 30, 2021 and December 31, 2020.

PPP Loans

In conjunction with the acquisition of WIC, the Company acquired two Federal Paycheck Protection Program Loans ("PPP Loans") with a principal balance of $243. As of September 30, 2021, one loan with a principal balance of $55 had been fully forgiven. The outstanding balance for the remaining loan was $188 as of September 30, 2021.

Note 7. Revenue from Contracts with Customers

Revenue from contracts with customers, included in other revenue, includes brokerage, management, third-party administrative, and consulting and other fee-based revenue. Revenue from contracts with customers was $2,799 and $8,683 for the three and nine months ended September 30, 2021, respectively, compared to $5,401 and $11,323 for the three and nine months ended September 30, 2020, respectively.

The following table presents the revenues recognized from contracts with customers included in the condensed consolidated statements of operations.

	Three Months Ended September 30,				Nine Months Ended September 30,
	2021		2020		2021		2020

	September 30, 2021		December 31, 2020
Contract assets	$	4,537	$	3,405

Note 8. Income Taxes

Income tax expense for interim periods is measured using an estimated effective income tax rate for the annual period. The Company's effective tax rate was 24.2% and 22.0% for the three and nine months ended months ended September 30, 2021. The increase in the effective tax rate from the statutory rate for these periods was primarily due to the impact of recording the Company's 2020 tax return accrual to return true-up in the third quarter of 2021.

The Company’s effective tax rate was 1.2% and 4.9% for the three and nine months ended September 30, 2020, respectively. The effective tax rate differed from the statutory rate primarily due the non-tax impact of the gain recorded on the revaluation of the Company's original 45% investment in Compstar, offset by certain IPO-related expenses not deductible for tax purposes.

During the three and nine months ended September 30, 2021, the reserves for unpaid losses and LAE developed favorably by $818 and $1,297, respectively, primarily attributable to the development in the Company's workers' compensation book of business. For the three and nine months ended September 30, 2020, the reserves for unpaid losses and LAE developed favorably by $300 and $2,372, respectively, primarily attributable to the development in the Company’s workers’ compensation book of business.

Note 10. Reinsurance

The Company utilizes reinsurance contracts to reduce its exposure to losses in all aspects of its insurance business. Such reinsurance permits recovery of a portion of losses from reinsurers, although it does not relieve the Company from its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial strength of potential reinsurers and continually monitors the financial condition of its reinsurers.

A summary of the impact of ceded reinsurance on premiums written and premiums earned is as follows:

	Three Months Ended September 30,
	2021								2020
	Gross		Assumed		Ceded		Net		Gross		Assumed		Ceded		Net
Written premiums	$	175,516	$	2,108	$	(114,374)	$	63,250	$	129,927	$	2,357	$	(94,083)	$	38,201

Note 11. Leases

The Company's leases consist of operating leases for office space and equipment. The Company determines if an arrangement is a lease at inception. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Some of the Company's leases include options to extend the term, which are only included in the lease liability and right-of-use asset calculation when it is reasonably certain the Company will exercise an option. Our leases have remaining terms ranging from one month to 45 months, some of which have options to extend the lease for up to 5 years. As of September 30, 2021, the lease liability and right-of-use assets did not include the impact of any lease extension options as it is not reasonably certain that the Company will exercise the extension options.

Total lease expense for the three months ended September 30, 2021 was $626, inclusive of $29 in variable lease expense. Total lease expense for the three months ended September 30, 2020 was $641, inclusive of $72 in variable lease expense. The Company also sublets some of its leased office space and recorded $33 and $11 of sublease income for the three months ended September 30, 2021 and 2020, respectively, which is included in other income on the condensed consolidated statement of operations.

Total lease expense for the nine months ended September 30, 2021 was $1,831, inclusive of $56 in variable lease expense. Total lease expense for the nine months ended September 30, 2020 was $1,755, inclusive of $214 in variable lease expense. The Company also sublets some of its leased office space and recorded $74 and $59 of sublease income for the nine months ended September 30, 2021 and 2020, respectively, which is included in other income on the condensed consolidated statement of operations.

Stock compensation expense related to stock option awards was $28 for the three and nine months ended September 30, 2020, respectively.

Employee stock option awards granted set forth, among other things, the option exercise price, the option term, provisions regarding option exercisability, and whether the option is intended to be an incentive stock option or a nonqualified stock option. Stock options may be granted to employees at such exercise prices as the Company’s board of directors may determine but not less than 100% of the fair market value of the underlying stock as of the date of grant. Employee options vest one third annually over a period of three years and have contractual terms of 10 years from the date of grant.

The fair value of each time-based vesting option award is estimated on the date of grant using the Black-Scholes option pricing model that uses assumptions noted in the following table. The Company’s expected volatility for the period is based on a weighted average expected volatility of an industry peer group of insurance companies of similar size, life cycle, and

lines of business. Expected term is calculated using the simplified method taking into consideration the option's contractual life and vesting terms. The Company’s stock option grants qualify as plain vanilla options and as such the Company uses the simplified method in estimating its expected option term as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited period of time its common shares have been publicly traded. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yields were not used in the fair value computations as the Company has never declared or paid dividends on its common stock and currently intends to retain earnings for use in operations.

	Fiscal 2021
Expected volatility	29.8%
Expected term	6 years
Risk-free interest rate	1.32%

A summary of the status of the Company's stock option activity as of September 30, 2021 and changes during the nine-month period then ended are as follows:

The weighted average grant-date fair value of options granted in the nine months ended September 30, 2021 was $5.49. As of September 30, 2021, total unrecognized compensation cost related to stock options was $422 and is expected to be recognized over a weighted average period of approximately 1.2 years.

Restricted Stock Units

Compensation expense relating to restricted stock unit grants was $419 and $980 for the three and nine months ended September 30, 2021, respectively. Compensation expense relating to restricted stock unit grants was $279 for the three and nine months ended September 30, 2020. As of September 30, 2021, there was $3,669 of total unrecognized compensation cost related to non-vested restricted stock unit grants, which is expected to be recognized over a weighted average life of 2.4 years. The total fair value of restricted stock units vested during the three and nine months ended September 30, 2021 was $342 and $478, respectively.

Table of Contents

The Company has granted time-based restricted stock units ("RSUs"), performance stock units ("PSUs"), and market-based stock units ("MSUs") to certain key employees as part of the Company's long-term incentive program. The estimated fair value of restricted stock units is based on the grant date closing price of the Company's stock for time-based and performance-based vesting awards. A Monte Carlo valuation model is used to estimate the fair value for market-based vesting awards. RSUs generally vest in three equal annual installments beginning one year from the grant date and are amortized as compensation expense over the three-year vesting period. The Company has also granted time-based restricted stock units to non-employee directors as part of the Company's annual director compensation program. Each time-based restricted stock grant to non-employee directors vests on the day immediately preceding the next annual meeting of stockholders following the date of grant. The grants are amortized as director compensation expense over the vesting period. The Company recognizes compensation expense on PSUs ratably over the requisite performance period of the award and to the extent management views the performance goal attainment as probable. The Company recognizes compensation expense on MSUs ratably over the requisite performance period of the award.

For the 2021 fiscal year, the Company granted PSUs to certain key employees pursuant to the Company's 2020 Omnibus Plan. The number of shares earned is based on the Company’s achievement of pre-established target threshold goals for total gross written premiums over a three-year performance measurement period. The performance goals allow for a payout ranging from 0% to 200% of the target award. If performance satisfies minimum requirements to result in shares being awarded, the number of shares will be determined between 50% and 200% of target thresholds, as defined in the applicable award agreements. Any earned PSU will vest if the employee’s service has been continuous through the vesting date. Any PSU not earned because of failure to achieve the minimum performance goal at the end of the performance period will be immediately forfeited. The grant date fair value of the PSUs was determined based on the grant date closing price of the Company’s stock.

For the 2021 fiscal year, the Company granted MSUs to certain key employees pursuant to the Company's 2020 Omnibus Plan. The number of restricted stock units earned is based on the Company’s cumulative total shareholder return ("TSR"), as defined in the applicable award agreement, over a three-year performance measurement period. If TSR satisfies minimum requirements to result in shares being awarded, the number of shares will be determined between 50% and 200% shown in the table below. Any MSU not earned because of failure to achieve the minimum performance goal at the end of the performance period will be immediately forfeited. Grant date fair values were determined using a Monte Carlo valuation model based on the following assumptions:

	Fiscal 2021
Total grant date fair value	$	845
Total grant date fair value per share	$	13.92
Expected volatility	35.0		%
Weighted average expected life	2.77 years
Risk-free interest rate	0.27		%

The percent of the target MSU that will be earned based on the Company’s TSR is as follows:

Cumulative TSR %	Percent of Units Vested
Below 25.1%	0%
25.1%	50%
47.2%	100%
69.3% and above	200%

On July 22, 2020, Trean Insurance Group, Inc. closed the sale of an additional 1,207,142 shares by certain selling stockholders in the IPO pursuant to the exercise of the underwriters’ option to purchase additional shares to cover over-allotments. The aggregate proceeds to the Company from all shares sold by the Company in the IPO were approximately $107,142 and the aggregate IPO proceeds from all shares sold by the selling stockholders in the IPO were approximately $71,678. The shares began trading on the Nasdaq Global Select Market on July 16, 2020 under the symbol "TIG."

Prior to the completion of the above IPO, the Company effected the following reorganization transactions: (i) each of Trean and BIC contributed all of their respective assets and liabilities to Trean Insurance Group, Inc., a newly formed direct subsidiary of BIC, in exchange for shares of common stock in Trean Insurance Group, Inc. and (ii) upon the completion of the transfers by Trean and BIC, Trean and BIC were dissolved and distributed in-kind common shares to the pre-IPO unitholders.

In conjunction with the IPO and corporate restructuring, the Company made a payment to Altaris Capital Partners, LLC in connection with the termination of the Company's consulting and advisory agreements as well as paid bonuses to employees and pre-IPO unitholders for the successful completion of the IPO. The aggregate amount of these payments totaled $11,054.

Embedded Derivatives

During the second quarter of 2021, the Company determined that its funds held agreements with reinsurers contain embedded derivatives relating to a total return swap on the underlying investments. As a result, the Company has revised the presentation of its financial results to report the change in fair value of the embedded derivatives in gains (losses) on embedded derivatives in the condensed consolidated statements of operations. In addition, the effect of investment earnings and realized capital gains (losses) related to funds held accounts will also be reported in gains (losses) on embedded derivatives in the condensed consolidated statements of operations, whereas previously these were reported as an offset to net investment income and net realized capital gains (losses), respectively. While the prior period amounts have been corrected for comparability, the correction was not material to the previously reported condensed consolidated and condensed combined financial statements.

Coronavirus ("COVID-19") Impact

We are monitoring the impact of the ongoing continuation of the COVID-19 pandemic on our business, including how it may impact our premium revenue, loss experience and loss expense, liquidity, and our regulatory capital and surplus, and operations.

Workforce Operations

Following the emergence of the COVID-19 pandemic in early 2020, we took a number of actions to protect the health of the public and our employees and to comply with directives and advice of governmental authorities and public health experts. We responded by developing a Preparedness Plan that outlined both corporate-wide and location-specific modifications to working conditions and operations in our offices. This multi-faceted plan included elements such as restricting business travel and transitioning from an office-based company to primarily a remote working culture. As most of our employees already had secure remote working connections, we took additional measures to ensure all employees who wanted or needed to work remotely were able to do so securely with limited connectivity disruption. We also provided our employees education and training with respect to cybersecurity issues that may arise relating to COVID-19 and working remotely in conjunction with the goal of serving the operational needs of a remote workforce and continuing to serve our customers. We implemented safeguards for employees who play critical roles to ensure operational reliability and established protocols for employees who interact directly with the public. As state, city, and county guidelines progress, we have implemented new health and safety in-office procedures and have launched our "Return to Office" plan to transition our workforce back to working in our offices while continuing to monitor the progression of the COVID-19 Delta Variant.

Premium Revenue, Claims and Losses

We have not experienced a material impact to our premium revenue in the first nine months of 2021 as a result of the COVID-19 pandemic. During the quarter ended September 30, 2021, compared to the quarter ended September 30, 2020, gross written premiums increased 34.3%, primarily driven by growth in our existing Program Partner business as well as the addition of new Program Partners, and gross earned premiums increased 36.4%, primarily driven by the increase in gross written premiums. During the nine months ended September 30, 2021, compared to the nine months ended September 30, 2020, gross written premiums increased by 37.5% and gross earned premiums increased by 34.1%, primarily driven by both significant growth in our existing Program Partner business as well as the addition of new Program Partners. Because a majority of our gross written premiums are related to workers’ compensation insurance, we expect that future revenue trends could be impacted. However, a significant portion of our workers’ compensation premiums are pay-as-you-go programs, which reduces our downside risk from future premium audits or refunds.

We also have not experienced a material impact in our reported claims or incurred losses in the first nine months of 2021 as a specific result of the COVID-19 pandemic. Our loss ratio increased to 61.8% and 61.5%, respectively, during the three and nine months ending September 30, 2021 from 55.9% and 56.7%, respectively, for the comparable 2020 periods. The increases in our loss ratios are attributable to a number of large unusual losses primarily incurred on our workers' compensation line of business as well as property losses incurred during the first half of 2021coupled with continued current year loss development.

Investment Portfolio

With respect to our investment portfolio, we seek to hold a high-quality, diversified portfolio of investments, which are primarily in fixed maturity and available-for-sale investments and, as such, our investment portfolio has limited exposure to the recent equity market volatility. For the nine months ended September 30, 2021, we experienced a decrease of $8,670, or 2.1%, in the fair value of our investment portfolio due to a reduction in unrealized gains on the value of our fixed maturity investments. The decline in the fair value of our fixed maturity investments is primarily attributable to rising interest rates following 2020 COVID-19 driven lower rates as opposed to underlying credit risk within our investment portfolio. If there were to be continued equity and debt financial market volatility, which in turn could create mark-to-market investment valuation decreases, we expect there could be additional or increased unrealized losses recorded during the balance of the year. However, given the conservative nature of our investment portfolio, we expect that any adverse impact on the value of our investment portfolio, as it relates to COVID-19, will be temporary, and we do not expect a long-term negative impact on our financial condition, results of operations or cash flows.

Other Concerns

Adverse events such as adverse changes in the overall public health environment resulting from changing infection patterns and other factors, variant strains of COVID-19, health-related concerns about working in our offices, ongoing restrictions on travel, the potential impact on our business partners and customers, and other matters affecting the general work and business environment could harm our business and delay the implementation of our business strategy. We cannot anticipate all the ways in which the current global health crisis and financial market conditions could adversely impact our business in the future.

Significant Components of Results of Operations

Gross written premiums: Gross written premiums are the amounts received or to be received for insurance policies written or assumed by us during a specific period of time without reduction for general and administrative expenses (including policy acquisition costs), reinsurance costs, or other deductions. The volume of our gross written premiums in any given period is generally influenced by:

•addition and retention of Program Partners;

•new business submissions to our Program Partners;

•binding of new business submissions into policies;

•renewals of existing policies; and

•average size and premium rate of bound policies.

Gross earned premiums: Gross earned premiums are the earned portion of gross written premiums. We earn insurance premiums on a pro rata basis over the term of the policy. Our insurance policies generally have a term of one year.

Ceded earned premiums: Ceded earned premiums are the amount of gross earned premiums ceded to reinsurers. We enter into reinsurance contracts to limit our maximum losses and diversify our exposure and provide statutory surplus relief. The volume of our ceded earned premiums is affected by the level of our gross earned premiums and any decision we make to increase or decrease limits, retention levels, and co-participations.

Net earned premiums: Net earned premiums represent the earned portion of our gross written premiums, less that portion of our gross written premiums that is earned and ceded to third-party reinsurers, including our Program Partners and professional reinsurers, under our reinsurance agreements.

Net investment income: We earn investment income on our portfolio of cash and invested assets. Our cash and invested assets are primarily comprised of fixed maturities, including other investments and short-term investments. Our net investment income includes interest income on our invested assets, income on funds held investments as well as unrealized gains and losses on our equity portfolio.

37

Table of Contents

Net realized capital gains/losses: Net realized capital gains/losses are a function of the difference between the amount received by us on the sale of a security and the security’s recorded value as well as any "other-than-temporary impairments" relating to fixed maturity investments recognized in earnings.

Other revenue: Other revenue includes brokerage, third-party administrative, management and consulting, and other fee-based revenues, which are commonly based on written premiums.

Loss and loss adjustment expenses: Losses and LAE are net of reinsurance and include claims paid, estimates of future claim payments, changes in those estimates from prior reporting periods, and costs associated with investigating, defending, and servicing claims. In general, our losses and LAE are affected by:

•frequency of claims associated with the particular types of insurance contacts that we write;

•trends in the average size of losses incurred on a particular type of business;

•mix of business written by us;

•changes in the legal or regulatory environment related to the business we write;

•trends in legal defense costs;

•wage inflation; and

•inflation in medical costs.

Losses and LAE are based on an actuarial analysis of the estimated losses, including losses incurred during the period and changes in estimates from prior periods. Losses and LAE may be paid out over a period of years.

General and administrative expenses: General and administrative expenses include net commissions, insurance-related expenses, and general and administrative operating expenses. Net commissions consist of policy acquisition costs and other underwriting expenses, net of ceding commissions. Policy acquisition costs are principally comprised of the commissions we pay our brokers and program managers. Policy acquisition costs that are directly related to the successful acquisition or reinsurance of those policies are deferred. All policy acquisition costs are charged to expense in proportion to premium earned over the policy life. We receive ceding commissions on business ceded under our reinsurance contracts. Insurance-related expenses largely consist of state premium taxes. General and administrative operating expenses include employee salaries and benefits, corporate insurance costs, technology costs, office rent, and professional services fees such as legal, accounting, audit, tax and actuarial services.

Intangible asset amortization: Intangible asset amortization consists of expenses incurred related to the amortization of intangible assets recorded as a result of business acquisitions and consists of trade names, customer lists and relationships, and non-compete agreements.

Noncash stock compensation: Noncash stock compensation includes expenses related to the fair value and issuance of restricted stock units and stock options.

Gains (losses) on embedded derivatives: Gains (losses) on embedded derivatives consist of the change in fair value of derivatives, the effect of net investment income on funds held investments, and the effect of realized gains and loss on funds held investments.

Interest expense: Interest expense consists primarily of interest paid on (i) our term loan facility and (ii) the preferred capital securities issued by the Trust (See "Financial Condition, Liquidity and capital resources — Debt and Credit Agreements").

Other income: Other income consists primarily of sublease revenue and other miscellaneous income items.

Equity earnings in affiliates, net of tax: Equity earnings in affiliates, net of tax includes the Company's share of earnings from equity method investments.

Key Metrics

We discuss certain key financial and operating metrics, described below, which provide useful information about our business and the operational factors underlying our financial performance.

Underwriting income is a non-GAAP financial measure defined as income before taxes excluding net investment income, investment revaluation gains, net realized capital gains or losses, intangible asset amortization, noncash stock compensation, gains and losses on embedded derivatives, interest expense, other revenue, and other income and expenses. See "Reconciliation of Non-GAAP Financial Measures" for a reconciliation of underwriting income to income before taxes in accordance with GAAP.

Adjusted net income is a non-GAAP financial measure defined as net income excluding the impact of certain items, including the consummation of the reorganization transactions in connection with our IPO, noncash intangible asset amortization and stock compensation, noncash unrealized gains and losses on embedded derivatives, other expenses and gains or losses that we believe do not reflect our core operating performance, which items may have a disproportionate effect in a given period, affecting comparability of our results across periods. See "Reconciliation of Non-GAAP Financial Measures" for a reconciliation of adjusted net income to net income in accordance with GAAP.

Loss ratio, expressed as a percentage, is the ratio of losses and LAE to net earned premiums.

Expense ratio, expressed as a percentage, is the ratio of general and administrative expenses to net earned premiums.

Combined ratio is the sum of the loss ratio and the expense ratio. A combined ratio under 100% generally indicates an underwriting profit. A combined ratio over 100% generally indicates an underwriting loss.

Return on equity is net income expressed on an annualized basis as a percentage of average beginning and ending stockholders' equity during the period.

Adjusted return on equity is a non-GAAP financial measure defined as adjusted net income expressed on an annualized basis as a percentage of average beginning and ending stockholders' equity during the period. See "Reconciliation of Non-GAAP Financial Measures" for a reconciliation of adjusted return on equity to return on equity in accordance with GAAP.

Tangible stockholders' equity is defined as stockholders' equity less goodwill and other intangible assets.

Return on tangible equity is a non-GAAP financial measure defined as net income expressed on an annualized basis as a percentage of average beginning and ending tangible stockholders' equity during the period. See "Reconciliation of Non-GAAP Financial Measures" for a reconciliation of return on tangible equity to return on equity in accordance with GAAP.

Adjusted return on tangible equity is a non-GAAP financial measure defined as adjusted net income expressed on an annualized basis as a percentage of average beginning and ending tangible stockholders' equity during the period. See "Reconciliation of Non-GAAP Financial Measures" for a reconciliation of adjusted return on tangible equity to return on tangible equity in accordance with GAAP.

Gross written premiums: Gross written premiums increased $45,340, or 34.3%, to $177,624 for the three months ended September 30, 2021, compared to $132,284 for the three months ended September 30, 2020. The increase is primarily attributable to the growth in our existing Program Partner business and the addition of new Program Partners. The changes in gross written premiums were due to the following:

Workers' compensation represented 54.3% of our gross written premiums for the three months ended September 30, 2021, compared to 72.7% for the three months ended September 30, 2020, primarily as a result of our ongoing strategic effort to diversify our lines of business. For the three months ended September 30, 2021, gross written premiums for workers' compensation increased by $343, or 0.4%, compared to the same period in 2020.

All other non-workers' compensation liability represented 45.7% of our gross written premiums for the three months ended September 30, 2021, compared to 27.3% for the three months ended September 30, 2020. For the three months ended September 30, 2021, gross written premiums for all other non-workers' compensation liability increased $44,997, or 124.4%, compared to the same period in 2020. The increase is due to growth in our other liability, accident & health, commercial auto and homeowners lines of business in keeping with our diversification.

Gross earned premiums: Gross earned premiums increased $39,825, or 36.4%, to $149,146 for the three months ended September 30, 2021, compared to $109,321 for the three months ended September 30, 2020.

The increase in ceded earned premiums is driven by the growth in gross earned premiums as described above, partially offset by an increase in our retention. Ceded earned premiums as a percentage of gross earned premiums decreased to 65.2% for the three months ended September 30, 2021, compared to 74.5% for the three months ended September 30, 2020, reflecting the Company's strategic decision to retain more gross written premiums.

Net earned premiums: Net earned premiums increased $24,099, or 86.5%, to $51,955 for the three months ended September 30, 2021, compared to $27,856 for the three months ended September 30, 2020.

Net investment income: Net investment income decreased $177, or 7.5%, to $2,187 for the three months ended September 30, 2021, compared to $2,364 for the three months ended September 30, 2020. The decrease largely reflects the reinvestment of funds from higher yielding maturities into lower yielding investments due to lower interest rates.

Net realized capital gains: Net realized capital gains decreased $66 to $49 for the three months ended September 30, 2021, compared to $115 for the three months ended September 30, 2020. The decrease is driven by a loss of $112 realized in the third quarter of 2021 on the Company's sale of its remaining investment in TRI.

Other revenue: Other revenue decreased $2,602, or 48.2%, to $2,799 for the three months ended September 30, 2021, compared to $5,401 for the three months ended September 30, 2020. The decrease is driven by a reduction in brokerage revenue of $2,433 due to due to a $2.2 million increase in estimated premiums and the timing of effective dates for brokered reinsurance contracts recognized in the third quarter of 2020. In addition, brokerage revenue was also reduced in 2021 due to the Company’s higher retention of brokered reinsurance contracts compared to the same prior-year period.

Losses and loss adjustment expenses: Losses and LAE increased $16,565, or 106.4%, to $32,129 for the three months ended September 30, 2021, compared to $15,564 for the three months ended September 30, 2020. The increase is attributable to the growth in gross earned premiums and increased retention during the three months ended September 30, 2021. This resulted in a loss ratio of 61.8% for the three months ended September 30, 2021 compared to 55.9% for the three months ended September 30, 2020. The increase is attributable to a number of unusually large losses experienced during the first half of 2021, resulting in a higher overall loss ratio pick related to the 2021 accident year.

General and administrative expenses: General and administrative expenses increased $6,793, or 97.1%, to $13,788 for the three months ended September 30, 2021, compared to $6,995 for the three months ended September 30, 2020.

Income tax expense: Income tax expense was $2,083 for the three months ended September 30, 2021, which resulted in an effective tax rate of 24.2%. The increase in the effective tax rate from the statutory rate of 21% is due primarily to the impact of recording our 2020 tax return accrual to return true-up in the third quarter of 2021. For the three months ended September 30, 2020 income tax expense was $817, which resulted in an effective tax rate of 1.2%. The decrease in the effective tax rate from the statutory rate of 21% is due primarily to the non-tax impact of the $69,846 gain recorded on the revaluation of the Company's original 45% investment in Compstar, offset by certain IPO-related expenses not deductible for tax purposes.

Equity earnings in affiliates, net of tax: Equity earnings in affiliates, net of tax decreased $401 to $0 for the three months ended September 30, 2021, compared to $401 for the three months ended September 30, 2020.

The increase is primarily attributable to the growth in our existing Program Partner business, the addition of new Program Partners and the acquisition of 7710 Insurance Company in the fourth quarter of 2020. The changes in gross written premiums were due to the following:

Workers' compensation represented 60.2% of our gross written premiums for the nine months ended September 30, 2021, compared to 76.8% for the nine months ended September 30, 2020, primarily as a result of our ongoing strategic effort to diversify our lines of business.

The decrease is primarily attributable to the fair value re-measurement and common stock investment reclassification of the Company's investment in TRI during the first quarter of 2020, which was previously classified as an equity method investment and resulted in a gain of $2,000. The decrease also reflects the reinvestment of funds from higher yielding maturities into lower yielding investments due to lower interest rates, partially offset by an increased in our invested balance.

Net realized capital gains: Net realized capital gains decreased $3,273 to $72 for the nine months ended September 30, 2021, compared to $3,345 for the nine months ended September 30, 2020.

This resulted in a loss ratio of 61.5% for the nine months ended September 30, 2021 compared to 56.7% for the nine months ended September 30, 2020. The increase is attributable to a number of unusually large losses experienced during the first half of 2021, resulting in a higher overall loss ratio pick related to the 2021 accident year.

Direct commissions increased $15,487 primarily due to an increase in gross earned premiums. Ceding commissions increased $10,472 due to an increase in ceded earned premiums reflecting the increase in gross earned premiums, partially offset by an increase in retention. Insurance-related expenses increased $3,310 primarily as a result of an increase in gross earned premiums. General and administrative operating expenses increased $9,184, primarily as a result of (i) an increase in salaries and benefits of $6,718, of which $3,423 directly resulted from acquisitions made in the second half of 2020 and a general increase in workforce; (ii) additional rent and office-related expenses totaling $1,771 due to an increase in business insurance expense as well as the addition of new office locations; and (iii) additional IT software and systems costs totaling $1,347 related to new software implementation and automation initiatives; partially offset by a decrease in professional fees of $1,220 as a result of the Company's IPO readiness effort in 2020.

Other expenses: Other expenses were $845 for the nine months ended September 30, 2021, which primarily relates to secondary offering costs of $555 and executive transition costs totaling $290. Other expenses were $11,054 for the nine months ended September 30, 2020, which consisted of one-time IPO bonuses and the termination of the Company's consultant and advisory agreement with Altaris Capital Partners, LLC.

Intangible asset amortization: Intangible asset amortization increased $3,172 to $4,326 for the nine months ended September 30, 2021, compared to $1,154 for the nine months ended September 30, 2020. The increase is driven by the addition of intangible assets acquired as a result of the purchase of the remaining equity interest of Compstar in the third quarter of 2020 and 7710 Insurance Company in the fourth quarter of 2020 and WIC in the third quarter of 2021.

Noncash stock compensation: Noncash stock compensation was $1,098 for the nine months ended September 30, 2021, compared with $307 for the nine months ended September 30, 2020. Expenses incurred during both periods relates to the fair value of restricted stock units and stock options granted under the Company's 2020 Omnibus Plan amortized over appropriate and applicable vesting periods.

Gains (losses) on embedded derivatives:

Table of Contents

The table below shows the components of gains (losses) on embedded derivatives for the respective nine-month periods:

	Nine Months Ended September 30,
	2021		2020		Change
Change in fair value of embedded derivatives	$	3,761	$	(3,066)	$	6,827
Effect of net investment income on funds held investments	(1,783)		(2,481)		698
Effect of realized gains on funds held investments	(109)		—		(109)
Total gains (losses) on embedded derivatives	$	1,869	$	(5,547)	$	7,416

Gains on embedded derivatives increased $7,416 to $1,869 for the nine months ended September 30, 2021, compared to losses of $5,547 for the nine months ended September 30, 2020. The gain reflected an increase in the fair value of embedded derivatives of $6,827 and the effect of investment income on funds held investments of $698, partially offset by the effect of realized gains on funds held investments of $109.

Income tax expense: Income tax expense was $5,102 for the nine months ended September 30, 2021, which resulted in an effective tax rate of 22.0%. The increase in the effective tax rate from the statutory rate of 21% is due primarily to the impact of recording our 2020 tax return accrual to return true-up in the third quarter of 2021. For the nine months ended September 30, 2020, income tax expense was $4,035, which resulted in an effective tax rate of 4.9%. The increase in the effective tax rate from the statutory rate of 21% is due primarily to the impact of state taxes and the deferred tax effect of a tax accounting method change on excess ceding commissions.

Equity earnings in affiliates, net of tax: Equity earnings in affiliates, net of tax decreased $2,333 to $0 for the nine months ended September 30, 2021, compared to $2,333 for the nine months ended September 30, 2020. This decrease is due to the reduction in the Company's share of earnings in Compstar of $2,333 as a result of the acquisition of the remaining ownership interest during the third quarter of 2020.

Owned MGA's and Program Partner Premiums:

The following table shows the total premiums earned on a gross and net basis for Owned MGAs and Program Partners:

(1) Direct commissions as a percentage of gross earned premiums.
(2) Ceding commissions as a percentage of ceded earned premiums.

We utilize both quota share and catastrophe XOL contracts in our reinsurance strategy for our Owned MGAs and Program Partners. Direct commissions for Program Partners include third-party agent commissions and MGA service fees, while Owned MGAs direct commissions includes only third-party agent commissions, while the expenses associated with MGA services are included in general and administrative operating expenses. The ceding commission rates vary based on a number

of factors including: the line of business, negotiated reinsurance terms, and program cost structures. For the nine months ended September 30, 2021, the Company retained 44.2% of gross earned premiums for Owned MGAs compared to 24.0% for Program Partners. The loss ratios for Owned MGAs and Program Partners for the nine months ended September 30, 2021was 59.8% and 64.4% respectively, resulting in a consolidated loss ratio of 61.5%. The higher loss ratio for Program Partners was primarily attributable to calendar year loss experience.

Reconciliation of Non-GAAP Financial Measures

Underwriting income

We define underwriting income as income before taxes excluding net investment income, investment revaluation gains, net realized capital gains or losses, IPO-related expenses, intangible asset amortization, noncash stock compensation, gains and losses on embedded derivatives, interest expense, other revenue, and other income and expenses. Underwriting income represents the pre-tax profitability of our underwriting operations and allows us to evaluate our underwriting performance without regard to investment income, IPO-related expenses, intangible asset amortization, noncash stock compensation, interest expense, other revenue and other income and expenses. We use this metric because we believe it gives our management and other users of our financial information useful insight into our underwriting business performance by adjusting for these expenses and sources of income. Underwriting income should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define underwriting income differently.

Adjusted net income

We define adjusted net income as net income excluding the impact of certain items, including the consummation of the reorganization transactions in connection with our IPO, noncash intangible asset amortization and stock compensation, noncash unrealized gains and losses on embedded derivatives, other expenses, and gains or losses that we believe do not reflect our core operating performance, which items may have a disproportionate effect in a given period, affecting comparability of our results across periods. We calculate the tax impact only on adjustments that would be included in calculating our income tax expense using the effective tax rate at the end of each period. We use adjusted net income as an internal performance measure in the management of our operations because we believe it gives our management and other users of our financial information useful insight into our results of operations and our underlying business performance by eliminating the effects of these items. Adjusted net income should not be viewed as a substitute for net income calculated in accordance with GAAP, and other companies may define adjusted net income differently.

Adjusted return on equity

We define adjusted return on equity as adjusted net income expressed on an annualized basis as a percentage of average beginning and ending stockholders' equity during the period. We use adjusted return on equity as an internal performance measure in the management of our operations because we believe it gives our management and other users of our financial information useful insight into our results of operations and our underlying business performance by adjusting for items that we believe do not reflect our core operating performance and that may diminish comparability across periods. Adjusted return on equity should not be viewed as a substitute for return on equity calculated in accordance with GAAP, and other companies may define adjusted return on equity differently.

Return on tangible equity and adjusted return on tangible equity

We define tangible stockholders' equity as stockholders' equity less goodwill and other intangible assets. We define return on tangible equity as net income expressed on an annualized basis as a percentage of average beginning and ending tangible stockholders' equity during the period. We define adjusted return on tangible equity as adjusted net income expressed on an annualized basis as a percentage of average beginning and ending tangible stockholders' equity during the period. We regularly evaluate acquisition opportunities and have historically made acquisitions that affect stockholders' equity. We use return on tangible equity and adjusted return on tangible equity as internal performance measures in the management of our operations because we believe they give our management and other users of our financial information useful insight into our results of operations and our underlying business performance by adjusting for the effects of acquisitions on our stockholders' equity and, in the case of adjusted return on tangible equity, by adjusting for the items that we believe do not reflect our core operating performance and that may diminish comparability across periods. Return on tangible equity and adjusted return on tangible equity should not be viewed as a substitute for return on equity or return on tangible equity, respectively, calculated in accordance with GAAP, and other companies may define return on tangible equity and adjusted return on tangible equity differently.

Financial Condition, Liquidity and Capital Resources

Sources and Uses of Funds

We are organized as a holding company with our operations conducted through our subsidiaries, including our wholly owned insurance subsidiaries: Benchmark, which is domiciled in Kansas and commercially domiciled in California; ALIC, which is domiciled in Utah; and 7710 Insurance Company, which is domiciled in South Carolina. Accordingly, the holding company may receive cash through: (i) loans from banks, (ii) draws on a revolving loan agreement, (iii) issuance of equity and debt securities, (iv) corporate service fees from our operating subsidiaries, (v) payments from our subsidiaries pursuant to our consolidated tax allocation agreement and other transactions and (vi) dividends from our non-insurance subsidiaries and, subject to certain limitations discussed below, dividends from our insurance subsidiaries. We also may use the proceeds from these sources to contribute funds to the insurance subsidiaries in order to support premium growth, reduce our reliance on reinsurance, pay taxes, and for other general business purposes.

Table of Contents

State insurance laws restrict the ability of insurance companies to declare stockholder dividends without prior regulatory approval. State insurance regulators require insurance companies to maintain specified levels of statutory capital and surplus.

Under Kansas and California law, dividends payable from Benchmark without the prior approval of the applicable insurance commissioner must not exceed the greater of (i) 10% of Benchmark's surplus as shown on the last statutory financial statement on file with the Kansas Insurance Department and the California Department of Insurance, respectively, or (ii) 100% of net income during the applicable twelve-month period (not including realized capital gains). Dividends shall not include pro rata distributions of any class of Benchmark's own securities.

Under Utah law, dividends payable from ALIC without the prior approval of the applicable insurance commissioner must not exceed the lesser of: (i) 10% of ALIC's surplus as shown on the last statutory financial statement on file with the Utah Insurance Department or (ii) 100% of net income during the applicable twelve- month period (not including realized capital gains).

Under South Carolina law, dividends payable from 7710 Insurance Company without the prior approval of the applicable insurance commissioner are limited to the following during the preceding twelve months: (a) when paid from other than earned surplus must not exceed the lesser of: (i) 10% of 7710 Insurance Company's surplus as regards policyholders as shown in 7710 Insurance Company's most recent annual statement; or (ii) the net income, not including net realized capital gains or losses as shown in 7710 Insurance Company's most recent annual statement; or (b) when paid from earned surplus must not exceed the greater of: (i) 10% of 7710 Insurance Company's surplus as regards policyholders as shown in 7710 Insurance Company's most recent annual statement; or (ii) the net income, not including net realized capital gains or losses as shown in the 7710 Insurance Company's most recent annual statement.

The maximum amount of dividends the insurance subsidiaries can pay us during 2021 without regulatory approval is $23,859. Insurance regulators have broad powers to ensure that statutory surplus remains at adequate levels, and there is no assurance that dividends of the maximum amount calculated under any applicable formula would be permitted. In the future, state insurance regulatory authorities that have jurisdiction over the payment of dividends by the insurance subsidiaries may adopt statutory provisions more restrictive than those currently in effect.

Our insurance subsidiaries are also required by state law to maintain a minimum level of policyholders' surplus. Kansas, Utah, and South Carolina utilize a risk-based capital requirement as promulgated by the National Association of Insurance Commissioners. Such requirements are designed to identify the various business risks (e.g., investment risk, underwriting profitability risk, etc.) of insurance companies and their subsidiaries. As of September 30, 2021 and December 31, 2020, the total adjusted capital of our insurance subsidiaries was in excess of their respective prescribed risk-based capital requirements.

As of September 30, 2021, we had $134,821 in cash and cash equivalents, compared to $153,149 as of December 31, 2020.

Management believes that we have sufficient liquidity available to meet our operating cash needs and obligations and committed capital expenditures for the next 12 months.

Cash Flows

Our most significant source of cash is from premiums received from insureds, net of the related commission amount for the policies. Our most significant cash outflow is for claims that arise when a policyholder incurs an insured loss. Because the payment of claims occurs after the receipt of the premium, often years later, we invest the cash in various investment securities that generally earn interest and dividends. The table below summarizes our net cash flows.

Financing activities	(1,125)		59,662
Net increase (decrease) in cash, cash equivalents and restricted cash	$	(18,846)	$	110,362

Operating Activities: Net cash provided by operating activities for the nine months ended September 30, 2021 was $53,410, compared to $32,208 for the same period in 2020. Net cash provided by operating activities includes net income as adjusted for depreciation and amortization, stock compensation, unrealized gains and losses on embedded derivatives, net capital gains and losses, bond amortization and accretion, the change in deferred income taxes, and amortization of deferred financing costs. Net cash provided by operating activities for the nine months ended September 30, 2021 reflects increases in unpaid loss and loss adjustment expenses of $52,975, unearned premiums of $64,879, and funds held under reinsurance agreements of $19,585; partially offset by increases in premiums and other receivables of $25,167, reinsurance recoverables of $18,460, prepaid reinsurance premiums of $30,252, other assets of $10,863 and decreases in reinsurance premiums payable of $7,829, and accounts payable and accrued expenses of $11,430. Unpaid loss and loss adjustment expenses and unearned premiums increased primarily due to an increase in gross written premiums. The increases in premiums and other receivables and reinsurance recoverables were primarily a result of an increase in gross written premiums during the period. Other assets increased as a result of increases in our deferred acquisition costs and contract asset balances. Funds held under reinsurance agreements decreased due to an arbitration settlement in the fourth quarter of 2020, resulting in the non-cash transfer of certain investments held as collateral. Excluding non-cash transfers, funds held under reinsurance agreements increased as a result of an increase in gross written premium. Net cash provided by operating activities for the nine months ended September 30, 2020 reflects distributions received from equity method investments and incremental cash received for operating assets and liabilities.

Investing Activities: Net cash used in investing activities for the nine months ended September 30, 2021 was $71,131 compared to net cash provided by investing activities of $18,492 for the same period in 2020.

Debt and Credit Agreements

First Horizon Credit Agreement

In April 2018, Trean Corporation and Trean Compstar entered into a credit agreement with First Horizon Bank (formerly, First Tennessee Bank National Association) (the "2018 First Horizon Credit Agreement"), which included a term loan facility totaling $27.5 million and a revolving credit facility of $3.0 million.

On May 26, 2020, the Company entered into an Amended and Restated Credit Agreement with First Horizon Bank, which, among other things, extended the Company's credit facility for a period of five years through May 26, 2025 and increased its term loan facility by $11,707, resulting in a total term loan debt amount of $33,000 and a revolving credit facility of $2,000. Borrowings under the facility are secured by substantially all of the assets of the Company other than Benchmark Holding Company and its subsidiaries. The loan has a variable interest rate of 3-month LIBOR plus 4.50%, which was 4.65% as of September 30, 2021 and 4.72% as of December 31, 2020 (under the 2018 First Horizon Credit Agreement). The outstanding principal balance of the loan is to be repaid in quarterly installments that escalate from approximately $206 to $825 until March 2025. All equity securities of the subsidiaries of the Company (other than Benchmark Holding Company and its subsidiaries) have been pledged as collateral.

Reinsurance

We cede a portion of the risk we accept on our balance sheet to third-party reinsurers through a variety of reinsurance arrangements. We manage these arrangements to align risks with our Program Partners, optimize our net retention relative to our financial objectives, balance sheet size and ratings requirements, as well as to limit our maximum loss resulting from a single program or a single event. We utilize both quota share and excess of loss ("XOL") reinsurance as tools in our overall risk management strategy to achieve these goals, usually in conjunction with each other. Quota share reinsurance involves the proportional sharing of premiums and losses of each defined program. We utilize quota share reinsurance for several purposes, including (i) to cede risk to Program Partners, which allows us to share economics and align incentives and (ii) to cede risk to third-party reinsurers in order to manage our net written premiums appropriately based on our financial objectives, capital base, A.M. Best financial strength rating and risk appetite. It is a core pillar of our underwriting philosophy that Program Partners retain a portion of the underwriting risk of their program. We believe this best aligns interests, attracts higher quality programs, and leads to better underwriting results. Under XOL reinsurance, losses in excess of a retention level are paid by the reinsurer, subject to a limit, and are customized per program or across multiple programs. We utilize XOL reinsurance to protect against catastrophic or other unforeseen extreme loss activity that could otherwise negatively impact our profitability and capital base. The majority of our exposure to catastrophe risk stems from the workers’ compensation premium we retain. Potential catastrophic events include an earthquake, terrorism, or another event that could cause more than one covered employee working at the same location to be injured in the event. We believe we mitigate this risk by our focus on small- to mid-sized accounts, which means that we generally do not have concentrated employee counts at single locations that could be exposed to a catastrophic loss. The cost and limits of the reinsurance coverage we purchase vary from year to year based on the availability of quality reinsurance at an acceptable price and our desired level of retention.

Ratings

We have a financial strength rating of "A" (Excellent) from A.M. Best. A.M. Best assigns 16 ratings to insurance companies, which currently range from "A++" (Superior) to "S" (Rating Suspended). "A" (Excellent) is the third highest rating issued by A.M. Best. The "A" (Excellent) rating is assigned to insurers that have, in A.M. Best's opinion, an excellent ability to meet their ongoing obligations to policyholders. This rating is intended to provide an independent opinion of an insurer’s ability to meet its obligation to policyholders and is not an evaluation directed at investors. See also "Risk factors — Risks related to our business and industry — A downgrade in the A.M. Best financial strength ratings of our insurance company subsidiaries may negatively affect our business." in our 2020 Form 10-K.

The financial strength ratings assigned by A.M. Best have an impact on the ability of the insurance companies to attract and retain agents and brokers and on the risk profiles of the submissions for insurance that the insurance companies receive. The "A" (Excellent) rating obtained by us is consistent with our business plan and allows us to actively pursue relationships with the agents and brokers identified in our marketing plan.

Contractual Obligations and Commitments

There have been no material changes in the Company's contractual obligations as of September 30, 2021 compared to December 31, 2020.

Financial condition

Stockholders' Equity

As of September 30, 2021, total stockholders' equity was $422,292, compared to $410,107 as of December 31, 2020, an increase of $12,185. The increase in stockholders' equity over the period was driven primarily by $11,180 of net comprehensive income.

We had $4,091 of unrecognized stock compensation as of September 30, 2021 related to non-vested stock compensation granted. The Company recognized $1,098 of stock compensation during the nine months ended September 30, 2021.

Investment Portfolio

Our invested asset portfolio consists of fixed maturities, equity securities, other investments, and short-term investments. The majority of the investment portfolio was comprised of fixed maturity securities of $425,596 at September 30, 2021, that were classified as available-for-sale. Available-for-sale investments are carried at fair value with unrealized gains and losses on these securities, net of applicable taxes, reported as a separate component of accumulated other comprehensive income.

Our investment portfolio objectives are to maintain liquidity, facilitating financial strength and stability and ensuring regulatory and legal compliance. Our investment portfolio consists of available-for-sale fixed maturities and other equity investments, all of which are carried at fair value. We seek to hold a high-quality portfolio of investments that is managed by a professional investment advisory management firm in accordance with the Company's investment policy and routinely reviewed by our management team. Our investments, however, are subject to general economic conditions and market risks as well as risks inherent to particular securities. The Company's investment portfolio has the following objectives:

•meet insurance regulatory requirements with respect to investments under the applicable insurance laws;

•maintain an appropriate level of liquidity to satisfy the cash requirements of current operations and long-term obligations;

•adjust investment risk to offset or complement insurance risk based on our total corporate risk tolerance; and

•realize the highest possible levels of investment income, while generating superior after-tax total rates of return.

Critical Accounting Policies and Estimates

The unaudited interim condensed consolidated financial statements included in this Quarterly Report on Form 10-Q include amounts based on the use of estimates and judgments of management.

We identified the accounting estimates that are critical to the understanding of our financial position and results of operations. Critical accounting estimates are defined as those estimates that are both important to the portrayal of our financial condition and results of operations and require us to exercise significant judgment. We use significant judgment concerning future results and developments in applying these critical accounting estimates and in preparing our condensed consolidated financial statements. These judgments and estimates affect our reported amounts of assets, liabilities, revenues and expenses and the disclosure of our material contingent assets and liabilities. Actual results may differ materially from the estimates and assumptions used in preparing the condensed consolidated financial statements. We evaluate our estimates regularly using information that we believe to be relevant. The estimates and judgments that are most critical to the preparation of the condensed consolidated financial statements include: (a) reserves for unpaid loss and LAE; (b) reinsurance recoveries; (c) investment fair value measurements; (d) goodwill and intangible assets; and (e) business combinations. For a detailed discussion of our accounting policies, see the "Notes to the Consolidated and Combined Financial Statements" included in our 2020 Form 10-K.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements as of September 30, 2021.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in interest rates, equity prices, foreign currency exchange rates, and commodity prices. The primary components of market risk affecting us are credit risk, interest rate risk, and equity rate risk, which are described in detail in Item 7A — "Quantitative and Qualitative Disclosures About Market Risk" in our 2020 Form 10-K. We do not have exposure to foreign currency exchange rate risk or commodity risk.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As of the end of the period covered by this report, management conducted an evaluation, under the supervision and with the participation of our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)). Based on this evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that 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 to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosures.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The effectiveness of any system of controls and procedures is subject to certain limitations, and, as a result, there can be no assurance that our controls and procedures will detect all errors or fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system will be attained.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time-to-time, the Company may be involved in legal proceedings which arise in the ordinary course of business. We believe that the outcome of such matters, individually or in the aggregate, will not have a material adverse effect on our consolidated financial position.

Item 1A. Risk Factors

We have disclosed in our 2020 Form 10-K the most significant risk factors that can impact year-to-year comparisons and that may affect the future performance of the Company's business. On a quarterly basis, we review these disclosures and update the risk factors, as appropriate. As of the date of this report, there have been no material changes to the risk factors from those disclosed in our 2020 Form 10-K.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business and Basis of Presentation

Business and Basis of Presentation

In July 2020, Trean Insurance Group, Inc. (together with its wholly owned subsidiaries, the "Company") completed its initial public offering ("IPO") of common stock. Prior to the completion of the IPO, the Company effected the following reorganization transactions: (i) each of Trean Holdings LLC ("Trean"), an insurance services company, and BIC Holdings LLC ("BIC"), a property and casualty insurance holding company, contributed all of their respective assets and liabilities to Trean Insurance Group, Inc., a newly formed direct subsidiary of BIC, in exchange for shares of common stock in Trean Insurance Group, Inc. and (ii) upon the completion of the transfers by Trean and BIC, Trean and BIC were dissolved and distributed in-kind common shares to the pre-IPO unitholders.

The Company provides products and services to the specialty insurance market. Historically, the Company has focused on specialty casualty markets that are believed to be under-served and where the Company’s expertise allows the Company to achieve higher rates, such as niche workers' compensation markets and small- to medium-sized specialty casualty insurance programs. The Company underwrites specialty-casualty insurance products both through programs where the Company partners with other organizations ("Program Partners"), and also through the Company’s own managing general agencies ("Owned MGAs"). The Company also provides Program Partners with a variety of services, including issuing carrier services, claims administration, and reinsurance brokerage from which the Company generates fee-based revenues.

The Company's wholly owned subsidiaries include: (a) Benchmark Holding Company, a property and casualty insurance holding company, which owns Benchmark Insurance Company ("Benchmark"), a property and casualty insurance company domiciled in the state of Kansas, American Liberty Insurance Company ("ALIC"), a property and casualty insurance company domiciled in the state of Utah, and 7710 Insurance Company, a property and casualty insurance company domiciled in the state of South Carolina; (b) Trean Compstar Holdings, LLC, a limited liability company created originally for the purchase of Compstar Insurance Services LLC, a California-based general agency; and (c) Trean Corporation ("Trean Corp"), a reinsurance intermediary manager and a managing general agent, which consists of the following wholly owned subsidiaries: Trean Reinsurance Services, LLC, a reinsurance intermediary broker; Benchmark Administrators LLC, a claims third-party administrator; Western Integrated Care, LLC, a managed care organization; and Westcap Insurance Services, LLC, a managing general agent based in California.

The accompanying condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to the Quarterly Report on Form 10-Q under the Securities Exchange Act of 1934. Accordingly, they do not contain all of the information included in the Company's annual consolidated financial statements and notes. In the opinion of management, all adjustments (consisting of normal, recurring adjustments) necessary for a fair presentation of the Company’s condensed consolidated financial position and results of operations for the periods presented have been included. Although management believes the disclosures and information presented are adequate, these interim condensed consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020 (the "2020 Form 10-K"). Operating results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021.

During the second quarter of 2021, the Company determined that its funds held agreements with reinsurers contain embedded derivatives relating to a total return swap on the underlying investments. As a result, the Company has revised the presentation of its financial results to report the change in fair value of the embedded derivatives in gains (losses) on embedded derivatives in the condensed consolidated and combined statements of operations. In addition, investment earnings credited to the funds withheld accounts are reported in gains (losses) on embedded derivatives in the condensed consolidated and combined statements of operations, whereas previously these were reported as an offset to net investment income. While the prior period amounts have been corrected for comparability, the correction was not material to the previously reported condensed consolidated and condensed combined financial statements. The impact of the prior period corrections on the condensed consolidated balance sheet and the related components of stockholders' equity is as follows:

	December 31, 2020						September 30, 2020
	Previously reported		Adjustment		As adjusted		Previously reported		Adjustment		As adjusted

Accumulated other comprehensive income	8,703		4,212		12,915		4,821		1,679		6,500

The impact of the prior period corrections on the condensed consolidated statements of operations and other comprehensive income is as follows:

The correction of the prior period amounts had no impact on total operating, investing, and financing activities as presented on the Company’s condensed consolidated statements of cash flows during the nine months ended September 30, 2020. In conjunction with the correction of the prior period amounts, the fair value leveling table as of December 31, 2020 in Note 3 was corrected from $174,704, which represented the total funds withheld under reinsurance agreements liability, to $4,937, which relates only to the fair value of the embedded derivative; the net investment income table in Note 4 was corrected to incorporate the income from funds held investments of $507 and $2,481 for the three and nine months ended September 30, 2020, respectively; the effective tax rate in Note 8 was corrected from 1.1% to 1.2% for the three months ended September 30, 2020 and from 5.5% to 4.9% for the nine months ended September 30, 2020; and Note 14 has been corrected to reflect the changes to other comprehensive income described above.

Use of estimates

While preparing the condensed consolidated financial statements, the Company has made certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements, as well as reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Reported amounts that require extensive use of estimates include the reserves for unpaid losses and loss adjustment expenses ("LAE"), reinsurance recoveries, investments, goodwill and other intangible assets. Except for the captions on the condensed consolidated balance sheets and condensed consolidated statements of comprehensive income, generally, the term loss(es) is used to collectively refer to both loss and LAE.

Accounting pronouncements

Recently adopted policies

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). This update provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This standard is effective for

the period between March 12, 2020 and December 31, 2022. The adoption of this standard did not have a material impact on the condensed consolidated financial statements.

Pending policies

The Company completed its IPO in July 2020, and is an emerging growth company as defined under federal securities laws. As such, the Company has elected to adopt pending accounting policies under the dates required for private companies. Therefore, the dates included within this section reflect the effective dates for the adoption of new accounting policies required by private companies.

In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments (ASU 2020-03). This update represents changes to clarify and improve the codification to allow for easier application by eliminating inconsistencies and providing clarification on items such as (i) the application of fair value option disclosures; (ii) the accounting for fees related to modifications of debt; and (iii) aligning the contractual term of a net investment in a lease in accordance with ASC Topic 326, Financial Instruments - Credit Losses, and the lease term determined in accordance with ASC Topic 842, Leases. The Company adopted items (i) and (ii) effective January 1, 2020 and will adopt item (iii) on January 1, 2023. Adoption of this standard has not had, and is not expected to have, a material impact on the condensed consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivative and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323 and Topic 815 (ASU 2020-01). This update addresses the accounting for certain equity securities upon the application or discontinuation of the equity method of accounting. Further, the update addresses scope considerations for forward contracts and purchased options on certain securities. ASU 2020-01 is effective for annual periods beginning after December 15, 2021, including interim periods thereafter. The Company will adopt this standard effective January 1, 2022. Adoption of this standard is not expected to have a material impact on the condensed consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (ASU 2016-13). This update requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. Additionally, credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses, with the amount of the allowance limited to the amount by which the fair value is below the amortized cost. ASU 2016-13 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. The Company will adopt this standard effective January 1, 2023. The Company is currently evaluating the impact of this standard on the condensed consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company’s financial instruments include assets and liabilities carried at fair value. The inputs to valuation techniques used to measure fair value are prioritized into a three level hierarchy. The fair value hierarchy is as follows:

Level 1: Fair values primarily based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2: Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.

Level 3: Fair values primarily based on valuations derived when one or more of the significant inputs are unobservable. With little or no observable market, the determination of fair value uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability.

The Company classifies the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value. The following tables present the estimated fair value of the Company’s significant financial instruments.

Bonds and equity securities: The Company, in conjunction with its third-party pricing service provider, uses a variety of sources to estimate the fair value of investments such as Reuters, Iboxx, PricingDirect, ICE BofAML Index, ICE Data Services, and for equities, Bloomberg. Equity securities are valued at the closing price on the exchange on which they are primarily traded as provided by a third-party pricing service. Fixed income securities are generally valued at an evaluated bid as provided by a third-party pricing service. Securities and other assets generally valued using third-party pricing services may also be valued at broker/dealer bid quotations. Values obtained from third-party pricing services can utilize several data sources for inputs such as transaction data, yield, quality, coupon rate, maturity, issue type, trading characteristics, and market activity. To validate the reasonableness of the quoted prices, the Company performs various qualitative and quantitative procedures such as analysis of recent trading activity, analytical review of fair values, and an evaluation of the underlying pricing methodologies. Based on these procedures, the Company did not adjust the prices or quotes from the third-party pricing service.

Embedded derivatives: The Company enters into funds held contracts under reinsurance agreements which create embedded derivatives on the underlying investments. These embedded derivatives are valued based upon the unrealized gain or loss position of the funds held portfolio, which is determined consistent with other investments using third-party pricing services. To validate the reasonableness of the quoted prices, the Company performs various qualitative and quantitative procedures such as analysis of recent activity, analytical review of fair values and an evaluation of the underlying pricing methodologies. Based on these procedures, the Company did not adjust the prices or quotes from the third-party pricing service.

Debt: The Company holds debt related to its secured credit facility. The Company has determined that the remaining balance of the debt reflected its fair value as this would represent the total amount to repay the debt.

Equity Method Investments and Joint Ventures [Abstract]

Equity Method Investments

Equity Method Investments

The Company held equity method investments in Compstar and Trean Intermediaries ("TRI"). Equity earnings and losses were reported in equity earnings in affiliates, net of tax on the condensed consolidated statements of operations.

On July 15, 2020, the Company purchased the remaining 55% ownership interest in Compstar and, as a result, Compstar is no longer recorded as an equity method investment. For the three and nine months ended September 30, 2020, the Company recorded earnings of $401 and $2,333, respectively, and received distributions of $540 and $2,842, respectively.

On January 3, 2020, the Company sold 15% of its previous 25% ownership in TRI for cash proceeds of $3,000 resulting in a remaining ownership interest of 10%. As a result of its significant ownership reduction and its lack of significant influence over the operations and policies of TRI, the Company reclassified its TRI investment, at fair value, to investments in common stock in the first quarter of 2020. The Company realized a gain on the sale of $3,115, which is included in net realized capital gains on the condensed consolidated statements of operations. The Company subsequently re-measured its TRI investment shares, resulting in an unrealized gain of $2,000, which is recorded in net investment income on the condensed consolidated statement of operations. The Company received distributions of $225 for the nine months ended September 30, 2020. The Company sold all of its remaining ownership interest in TRI during Q3 2021 for $1,888, resulting in a realized loss of $112, which is included in net realized capital gains on the condensed consolidated statement of operations.

Secured Credit Facility

In April 2018, Trean Corp entered into a credit agreement with a bank which includes a term loan facility totaling $27,500 and a revolving credit facility of $3,000. Borrowings are secured by substantially all of the assets of Trean and its subsidiaries.

On May 26, 2020, the Company entered into a new Amended and Restated Credit Agreement which, among other things, extended the Company's credit facility for a period of five years through May 26, 2025 and increased its term loan facility by $11,707, resulting in a total term loan debt amount of $33,000 at the time of closing. The loan has a variable interest rate of LIBOR plus 4.50%, which was 4.65% and 4.72% as of September 30, 2021 and December 31, 2020, respectively. The

Income Taxes

Income Taxes

Income tax expense for interim periods is measured using an estimated effective income tax rate for the annual period. The Company's effective tax rate was 24.2% and 22.0% for the three and nine months ended months ended September 30, 2021. The increase in the effective tax rate from the statutory rate for these periods was primarily due to the impact of recording the Company's 2020 tax return accrual to return true-up in the third quarter of 2021.

The Company’s effective tax rate was 1.2% and 4.9% for the three and nine months ended September 30, 2020, respectively. The effective tax rate differed from the statutory rate primarily due the non-tax impact of the gain recorded on the revaluation of the Company's original 45% investment in Compstar, offset by certain IPO-related expenses not deductible for tax purposes.

Reinsurance Disclosures [Abstract]

Reinsurance

Reinsurance

The Company utilizes reinsurance contracts to reduce its exposure to losses in all aspects of its insurance business. Such reinsurance permits recovery of a portion of losses from reinsurers, although it does not relieve the Company from its primary liability to policyholders. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial strength of potential reinsurers and continually monitors the financial condition of its reinsurers.

A summary of the impact of ceded reinsurance on premiums written and premiums earned is as follows:

Leases [Abstract]

Leases

Leases

The Company's leases consist of operating leases for office space and equipment. The Company determines if an arrangement is a lease at inception. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease right-of-use assets are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Some of the Company's leases include options to extend the term, which are only included in the lease liability and right-of-use asset calculation when it is reasonably certain the Company will exercise an option. Our leases have remaining terms ranging from one month to 45 months, some of which have options to extend the lease for up to 5 years. As of September 30, 2021, the lease liability and right-of-use assets did not include the impact of any lease extension options as it is not reasonably certain that the Company will exercise the extension options.

Total lease expense for the three months ended September 30, 2021 was $626, inclusive of $29 in variable lease expense. Total lease expense for the three months ended September 30, 2020 was $641, inclusive of $72 in variable lease expense. The Company also sublets some of its leased office space and recorded $33 and $11 of sublease income for the three months ended September 30, 2021 and 2020, respectively, which is included in other income on the condensed consolidated statement of operations.

Total lease expense for the nine months ended September 30, 2021 was $1,831, inclusive of $56 in variable lease expense. Total lease expense for the nine months ended September 30, 2020 was $1,755, inclusive of $214 in variable lease expense. The Company also sublets some of its leased office space and recorded $74 and $59 of sublease income for the nine months ended September 30, 2021 and 2020, respectively, which is included in other income on the condensed consolidated statement of operations.

Share-based Payment Arrangement [Abstract]

Stock Compensation

Stock Compensation

As of September 30, 2021, the Company has one incentive plan, the Trean Insurance Group, Inc. 2020 Omnibus Incentive Plan, (the "2020 Omnibus Plan"). The purposes of the 2020 Omnibus Plan are to provide additional incentive to selected officers, employees, non-employee directors, independent contractors, and consultants of the Company whose contributions are essential to the growth and success of the business of the Company and its affiliates, to strengthen the commitment and motivate such individuals to faithfully and diligently perform their responsibilities and to attract competent and dedicated individuals whose efforts will result in the long-term growth and profitability of the Company and its affiliates. The 2020 Omnibus Plan is administered by the Compensation, Nominating, and Corporate Governance Committee of the Company's board of directors and provides for the issuance of up to 5,058,085 shares of the Company's common stock granted in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, stock bonuses, other stock awards, or any combination of the foregoing.

Stock Options

Compensation expense is recognized for all stock compensation arrangements by the Company. Stock compensation expense related to stock option awards was $49 and $118 for the three and nine months ended September 30, 2021, respectively. Stock compensation expense related to stock option awards was $28 for the three and nine months ended September 30, 2020, respectively.

Employee stock option awards granted set forth, among other things, the option exercise price, the option term, provisions regarding option exercisability, and whether the option is intended to be an incentive stock option or a nonqualified stock option. Stock options may be granted to employees at such exercise prices as the Company’s board of directors may determine but not less than 100% of the fair market value of the underlying stock as of the date of grant. Employee options vest one third annually over a period of three years and have contractual terms of 10 years from the date of grant.

The fair value of each time-based vesting option award is estimated on the date of grant using the Black-Scholes option pricing model that uses assumptions noted in the following table. The Company’s expected volatility for the period is based on a weighted average expected volatility of an industry peer group of insurance companies of similar size, life cycle, and

lines of business. Expected term is calculated using the simplified method taking into consideration the option's contractual life and vesting terms. The Company’s stock option grants qualify as plain vanilla options and as such the Company uses the simplified method in estimating its expected option term as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited period of time its common shares have been publicly traded. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend yields were not used in the fair value computations as the Company has never declared or paid dividends on its common stock and currently intends to retain earnings for use in operations.

	Fiscal 2021
Expected volatility	29.8%
Expected term	6 years
Risk-free interest rate	1.32%

A summary of the status of the Company's stock option activity as of September 30, 2021 and changes during the nine-month period then ended are as follows:

	Stock Options	Weighted Average Exercise Price
Balance outstanding, December 31, 2020	89,920	$	15.00
Granted	60,729	$	17.50
Forfeited or cancelled	(27,646)	$	15.64
Balance outstanding, September 30, 2021	123,003	$	16.09
Options exercisable, September 30, 2021	24,351	$	15.00

The following table summarizes information regarding stock options outstanding as of September 30, 2021:

	Options Outstanding						Options Vested or Expected to Vest
Stock Options	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contract Term	Aggregate Intrinsic Value		Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Contract Term	Aggregate Intrinsic Value
2020 Omnibus Plan	123,003	$	16.09	8.97 years	$	—	123,003	$	16.09	8.97 years	$	—

The weighted average grant-date fair value of options granted in the nine months ended September 30, 2021 was $5.49. As of September 30, 2021, total unrecognized compensation cost related to stock options was $422 and is expected to be recognized over a weighted average period of approximately 1.2 years.

Restricted Stock Units

Compensation expense relating to restricted stock unit grants was $419 and $980 for the three and nine months ended September 30, 2021, respectively. Compensation expense relating to restricted stock unit grants was $279 for the three and nine months ended September 30, 2020. As of September 30, 2021, there was $3,669 of total unrecognized compensation cost related to non-vested restricted stock unit grants, which is expected to be recognized over a weighted average life of 2.4 years. The total fair value of restricted stock units vested during the three and nine months ended September 30, 2021 was $342 and $478, respectively.

The Company has granted time-based restricted stock units ("RSUs"), performance stock units ("PSUs"), and market-based stock units ("MSUs") to certain key employees as part of the Company's long-term incentive program. The estimated fair value of restricted stock units is based on the grant date closing price of the Company's stock for time-based and performance-based vesting awards. A Monte Carlo valuation model is used to estimate the fair value for market-based vesting awards. RSUs generally vest in three equal annual installments beginning one year from the grant date and are amortized as compensation expense over the three-year vesting period. The Company has also granted time-based restricted stock units to non-employee directors as part of the Company's annual director compensation program. Each time-based restricted stock grant to non-employee directors vests on the day immediately preceding the next annual meeting of stockholders following the date of grant. The grants are amortized as director compensation expense over the vesting period. The Company recognizes compensation expense on PSUs ratably over the requisite performance period of the award and to the extent management views the performance goal attainment as probable. The Company recognizes compensation expense on MSUs ratably over the requisite performance period of the award.

For the 2021 fiscal year, the Company granted PSUs to certain key employees pursuant to the Company's 2020 Omnibus Plan. The number of shares earned is based on the Company’s achievement of pre-established target threshold goals for total gross written premiums over a three-year performance measurement period. The performance goals allow for a payout ranging from 0% to 200% of the target award. If performance satisfies minimum requirements to result in shares being awarded, the number of shares will be determined between 50% and 200% of target thresholds, as defined in the applicable award agreements. Any earned PSU will vest if the employee’s service has been continuous through the vesting date. Any PSU not earned because of failure to achieve the minimum performance goal at the end of the performance period will be immediately forfeited. The grant date fair value of the PSUs was determined based on the grant date closing price of the Company’s stock.

For the 2021 fiscal year, the Company granted MSUs to certain key employees pursuant to the Company's 2020 Omnibus Plan. The number of restricted stock units earned is based on the Company’s cumulative total shareholder return ("TSR"), as defined in the applicable award agreement, over a three-year performance measurement period. If TSR satisfies minimum requirements to result in shares being awarded, the number of shares will be determined between 50% and 200% shown in the table below. Any MSU not earned because of failure to achieve the minimum performance goal at the end of the performance period will be immediately forfeited. Grant date fair values were determined using a Monte Carlo valuation model based on the following assumptions:

	Fiscal 2021
Total grant date fair value	$	845
Total grant date fair value per share	$	13.92
Expected volatility	35.0		%
Weighted average expected life	2.77 years
Risk-free interest rate	0.27		%

The percent of the target MSU that will be earned based on the Company’s TSR is as follows:

Cumulative TSR %	Percent of Units Vested
Below 25.1%	0%
25.1%	50%
47.2%	100%
69.3% and above	200%

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Use of estimates

Use of estimates

While preparing the condensed consolidated financial statements, the Company has made certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the condensed consolidated financial statements, as well as reported amounts of revenue and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Reported amounts that require extensive use of estimates include the reserves for unpaid losses and loss adjustment expenses ("LAE"), reinsurance recoveries, investments, goodwill and other intangible assets. Except for the captions on the condensed consolidated balance sheets and condensed consolidated statements of comprehensive income, generally, the term loss(es) is used to collectively refer to both loss and LAE.

Accounting pronouncements

Accounting pronouncements

Recently adopted policies

In March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"). This update provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. This standard is effective for

the period between March 12, 2020 and December 31, 2022. The adoption of this standard did not have a material impact on the condensed consolidated financial statements.

Pending policies

The Company completed its IPO in July 2020, and is an emerging growth company as defined under federal securities laws. As such, the Company has elected to adopt pending accounting policies under the dates required for private companies. Therefore, the dates included within this section reflect the effective dates for the adoption of new accounting policies required by private companies.

In March 2020, the FASB issued ASU No. 2020-03, Codification Improvements to Financial Instruments (ASU 2020-03). This update represents changes to clarify and improve the codification to allow for easier application by eliminating inconsistencies and providing clarification on items such as (i) the application of fair value option disclosures; (ii) the accounting for fees related to modifications of debt; and (iii) aligning the contractual term of a net investment in a lease in accordance with ASC Topic 326, Financial Instruments - Credit Losses, and the lease term determined in accordance with ASC Topic 842, Leases. The Company adopted items (i) and (ii) effective January 1, 2020 and will adopt item (iii) on January 1, 2023. Adoption of this standard has not had, and is not expected to have, a material impact on the condensed consolidated financial statements.

In January 2020, the FASB issued ASU No. 2020-01, Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivative and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323 and Topic 815 (ASU 2020-01). This update addresses the accounting for certain equity securities upon the application or discontinuation of the equity method of accounting. Further, the update addresses scope considerations for forward contracts and purchased options on certain securities. ASU 2020-01 is effective for annual periods beginning after December 15, 2021, including interim periods thereafter. The Company will adopt this standard effective January 1, 2022. Adoption of this standard is not expected to have a material impact on the condensed consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (ASU 2016-13). This update requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that runs through net income. Additionally, credit losses relating to available-for-sale debt securities will also be recorded through an allowance for credit losses, with the amount of the allowance limited to the amount by which the fair value is below the amortized cost. ASU 2016-13 is effective for annual periods beginning after December 15, 2022, including interim periods within those fiscal years. The Company will adopt this standard effective January 1, 2023. The Company is currently evaluating the impact of this standard on the condensed consolidated financial statements.

Fair value measurements

Fair Value Measurements

The Company’s financial instruments include assets and liabilities carried at fair value. The inputs to valuation techniques used to measure fair value are prioritized into a three level hierarchy. The fair value hierarchy is as follows:

Level 1: Fair values primarily based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2: Fair values primarily based on observable inputs, other than quoted prices included in Level 1, or based on prices for similar assets and liabilities.

Level 3: Fair values primarily based on valuations derived when one or more of the significant inputs are unobservable. With little or no observable market, the determination of fair value uses considerable judgment and represents the Company’s best estimate of an amount that could be realized in a market exchange for the asset or liability.

The Company classifies the financial asset or liability by level based upon the lowest level input that is significant to the determination of the fair value.
