SAFE HARBOR STATEMENT

This Annual Report on Form 10-K (including any information incorporated herein by reference) contains, and future oral and written statements of Heartland Financial USA, Inc. ("HTLF") and its management may contain, forward-looking statements within the meaning of such term in Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act") with respect to the business, financial condition, results of operations, plans, objectives and future performance of HTLF. Any statements about HTLF's expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and may be forward-looking. Forward-looking statements may include information about possible or assumed future results of HTLF's operations or performance, and may be based upon beliefs, expectations and assumptions of HTLF's management. These forward-looking statements are generally identifiable by the use of words such as "believe," "expect," "anticipate," "plan," "intend," "estimate," "project," "may," "will," "would," "could," "should," "view," "opportunity," "potential," or other similar expressions. Although HTLF has made these statements based on management's experience and best estimate of future events, the ability of HTLF to predict results or the actual effect or outcomes of plans or strategies is inherently uncertain, and there may be events or factors that management has not anticipated. Therefore, the accuracy and achievement of such forward-looking statements and estimates are subject to a number of risks, many of which are beyond the ability of management to control or predict, that could cause actual results to differ materially from those in its forward-looking statements. These factors, which HTLF currently believes could have a material adverse effect on its operations and future prospects are detailed in the "Risk Factors" section included under Item 1A of Part I of this Annual Report on Form 10-K, include, among others:

•Economic and Market Conditions Risks, including risks related to the deterioration of the U.S. economy in general and/or in the local economies in which HTLF conducts its operations, volatility in the debt and equity markets, impairments of the value of our goodwill or tax assets, changes in tax laws, natural disasters, climate change and climate-related regulations, persistent inflation, interest rate fluctuation, recession, labor shortages, terrorist threats or geopolitical conflict;

•Credit Risks, including risks of increasing credit losses due to deterioration in the financial condition of HTLF's borrowers, changes in asset and collateral values due to borrower industry risks or climate and other risks, which may impact the provision for credit losses and net charge-offs;

•Liquidity and Interest Rate Risks, including unfavorable interest rate levels or rapid changes in interest rates, inability to meet our liquidity needs, loss of deposits, increased funding costs, and changes in the value of our investment;

•Operational Risks, including risks related to information systems, cybersecurity, third-party vendor, business interruption, cyber security incidents and fraud, internal controls, technology expense, loss of key personnel, new products;

•Strategic and External Risks, including risks related to the soundness of other financial institutions execution of our growth strategy, including acquisitions that we may make;

•Legal, Compliance and Reputational Risks, including regulatory and litigation risks; and

•Risks of Owning Stock in HTLF, including stock price volatility and dilution as a result of future equity offerings and acquisitions.

However, there can be no assurance that other factors not currently anticipated by HTLF will not materially and adversely affect HTLF’s business, financial condition and results of operations. Additionally, all statements in this Annual Report on Form 10-K, including forward-looking statements, speak only as of the date they are made. HTLF does not undertake and specifically disclaims any obligation to publicly release the results of any revisions which may be made to any forward-looking statement to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events or to otherwise update any statement in light of new information or future events. Further information concerning HTLF and its business, including additional factors that could materially affect HTLF’s financial results, is included in HTLF’s filings with the Securities and Exchange Commission (the "SEC").

All of HTLF’s subsidiaries were wholly owned as of December 31, 2023.

The principal business of our Banks consists of making loans to and accepting deposits from businesses and consumers, while offering other related bank products and services. Our Banks provide full service commercial and consumer banking in their communities. Both our loans and our deposits are generated primarily through strong banking and market knowledge as well as customer relationships, guided by management that is actively involved in the community. Our lending and investment activities are funded primarily by core deposits. This stable source of funding is achieved by developing banking relationships with customers through value-added product offerings, competitive market pricing, convenience and high-touch personal

service. Deposit products, which are insured by the FDIC to the full extent permitted by law, include checking and other demand deposit accounts, NOW accounts, savings accounts, money market accounts, certificates of deposit, individual retirement accounts and other time deposits. Loan products include commercial and industrial, commercial real estate, agricultural, small business, real estate mortgage, consumer, and credit cards for commercial business use.

We enhance the customer-centric local services in our Bank Markets with a full complement of value-added services, including wealth management, investment and retirement plan services. We provide technology solutions that provide our customers convenient electronic banking services and access to account information through business and personal online banking, mobile banking, bill payment, remote deposit capture, treasury management services, credit and debit cards and automated teller machines.

Business Model and Operating Philosophy

HTLF’s operating philosophy is to maximize the benefits of our community-focused banking model by:

1.Creating strong community ties through customer-centric local bank delivery of products and services.

•Deeply rooted local management and advisory boards

•Local community knowledge and relationships

•Local decision-making

•Locally recognized brands

•Commitment to an exceptional customer experience

2.Providing extensive banking services to increase revenue.

•Full range of commercial products and services, including government guaranteed lending and treasury management services

•Specialized industries division and capital markets team providing middle-market lending expertise

•Providing added client value through consultative relationship building

•Convenient and competitive consumer products and services

•Private client services, including investment management, trust, retirement plans, brokerage services and investment services

3.Centralizing back-office operations for efficiency and enhancing the customer experience.

•Leverage expertise across HTLF Bank

•Contemporary technology for account processing and delivery systems

•Efficient back-office support for loan processing and deposit operations

•Centralized customer relationship management systems

•Centralized loan underwriting and collections

•Centralized loss management and risk analysis

•Centralized support for other professional services, including information technology, human resources, marketing, legal, compliance, finance, administration, internal audit, fraud and enterprise risk management, investment management, customer support and facilities management.

We believe the personal and professional service we offer to our customers provides an appealing alternative to the service provided by the "megabanks" or large regional banks. While we are committed to a community-focused banking philosophy, we believe our size, combined with our robust suite of financial products and services, allows us to nimbly and effectively compete in our respective market areas. To remain price competitive, we also believe that we must manage expenses and gain economies of scale by centralizing back-office support functions. We have standard policies and procedures regarding asset/liability and investment management, compliance and risk management, credit risk, and deposit structure management, information technology management and security management.

Another component of our operating strategy is to require all directors and officers to maintain an ownership interest in HTLF, and to create a culture of ownership with all employees by facilitating stock ownership. We have established ownership guidelines for our directors and executive officers. We also have a long-terms incentive plan through which we grant equity-based awards to eligible employees, and an employee stock purchase plan through which we facilitate stock ownership by offering stock to all employees at a discount.

We are deeply committed to our communities through lending, investments and service activities such as active participation by our employees, officers and board members in local charitable, civic, school, religious and community development activities.

Market Focus, Branch Optimization, and Acquisition Strategies

In addition to our focus on organic growth, HTLF continues to evaluate opportunities to augment our business through acquiring businesses that complement or supplement our current banking strategy. This includes transactions that increase penetration in existing geographic Bank Markets and expansion into adjacent markets. In addition to acquisitions of established financial institutions, primarily commercial banks, HTLF also considers acquisitions of fee income businesses that complement and build on our existing businesses, or further meet the needs of our customers. Moreover, HTLF continues to explore the expansion of its lending products and services through the acquisition of specialty lending, equipment finance, leasing and other services to expand our product and service offerings. All acquisition opportunities are evaluated using a range of financial and non-financial criteria, including earnings per share accretion, tangible equity earn back, internal rate of return, operational synergies and strategic fit.

We have focused our investments and previous acquisitions on markets with growth potential in the Midwestern, Southwestern and Western regions of the United States. Our overall strategy is to balance the growth in our Southwestern and Western Bank Markets with the stability of our Midwestern Bank Markets.

Due to changes in our customers' banking preferences and behaviors driven by the evolving digital and competitive landscape, we continue to evaluate our branch footprint and have selectively sold, consolidated and closed branches. We anticipate these strategic activities will provide additional resources to support our investments in areas that enhance our customer relationships and experiences, while fueling organic growth opportunities. As a result of our ongoing branch optimization, we may complete additional, selective reductions in our branch network in the future.

HTLF completed strategic divestitures of certain non-core assets during 2023. Dubuque Bank & Trust, a division of HTLF Bank, sold and transferred the recordkeeping and administration services component of HTLF’s Retirement Plan Services business to July Business Services ("July"). Through the new partnership with July, HTLF expects to augment the comprehensive retirement plan solutions offered to clients with enhanced technology and an expanded suite of product offerings that clients expect from a top retirement services provider. The transaction was completed, and recordkeeping and administration services were transferred in the second quarter of 2023. First Bank & Trust, a division of HTLF Bank, completed the sale of its mortgage servicing rights portfolio during the first quarter of 2023, which consisted of approximately 4,500 loans serviced for others with an unpaid principal balance of $698.5 million.

Subsequent to December 31, 2023, in February of 2024, HTLF announced that HTLF Bank had signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024. The sales are expected to improve capital levels and allow for increased focus and investment in bank markets with higher future growth potential.

Primary Business Lines

General

We are engaged in the business of banking, with the expertise to serve a wide range of businesses and the scale to compete at many levels. Our Banks provide a wide range of commercial, small business and consumer banking services to businesses, including public sector and non-profit entities, and to individuals. Each Bank also has access to a centralized team of middle-market lenders with expertise in specific industries and loan structures allowing us to retain growing customers and seek new attractive customer opportunities. We have a broad and diverse customer base and do not depend upon a small number of customers. Our extensive customer base across our Bank Markets spans a multitude of diversified industries and geographies. We provide multiple service delivery channels, including online banking, mobile/remote banking and telephone banking. Our Banks provide a comprehensive suite of banking products and services comprised of competitively priced deposit and credit offerings, along with treasury management, wealth management and retirement plan services.

Our bankers actively solicit new and established businesses in their respective business communities. We believe that HTLF Bank is successful in attracting new customers in their markets through knowledgeable and experienced bankers, professional high-touch service, a suite of comprehensive credit and non-credit banking products and services, competitive pricing, convenient locations and proactive communications.

We deliver the following products and services throughout our Bank Markets:

Commercial Banking

Our Banks have a strong commercial loan base generated primarily through established longstanding reputations, business networks and personal relationships in the communities they serve. The current portfolios in each Bank Market reflect the businesses in those communities and include a wide range of business loans, including lines of credit for working capital and operational purposes. Commercial real estate loans, which include owner occupied and non-owner occupied real estate loans, are generally term loans originated for the acquisition of real estate and equipment. Although most loans are made on a secured basis, loans may be made on an unsecured basis when warranted by the overall financial condition and cash flow of the borrower. Generally, terms of commercial and commercial real estate loans range from one to five years.

Commercial bankers provide a consultative customer-centric approach utilizing our comprehensive suite of banking products and services to deliver solutions designed to fit the objectives of the client in an organized and efficient manner. Bankers are knowledgeable and experienced in providing consultative solutions to clients to assist them in accomplishing their business strategies and objectives. The suite of banking products and services offered are highly competitive and can be tailored to fit the needs of the customer.

Closely integrated with our lending activities is a significant emphasis on treasury management services that enhance our business clients' ability to monitor, accumulate and disburse funds efficiently. Our treasury management services have five basic functions:

•collection

•disbursement

•management of cash

•information reporting

•fraud prevention

Our Treasury and Payment Solutions Suite includes a full array of services designed to meet the needs of commercial clients. Our services include: online banking with custom statement formatting and multiple delivery options, same day and prior day information reporting, bill payment, same day and next day automated clearing house ("ACH") services, wire transfers, insured cash sweeps ("ICS"), zero balance accounts, lockbox, image cash letter, remote deposit capture, commercial cards for travel and entertainment purchasing, merchant services to receive credit card payments, investment sweep accounts, reconciliation services, online invoice processing, foreign exchange and positive pay fraud prevention services for checks and ACH payments.

Our commercial and commercial real estate loans are primarily made based on the identified cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. We value the collateral for most of these loans based upon its estimated fair market value and require personal guarantees in the majority of instances. The primary repayment risks of commercial and commercial real estate loans are that the cash flow of the borrowers may be unpredictable, and the collateral securing these loans may fluctuate in value.

Many of the businesses in the communities we serve are small to middle market businesses, and commercial lending to these businesses has been, and continues to be, an emphasis for HTLF Bank. Lenders in each Bank Market are complemented by HTLF Specialized Industries, a centralized team of highly experienced middle-market lenders focused on specific industries and more complex loan structures. This team includes specialized expertise in commercial real estate, healthcare, food and agribusiness, and franchise finance, as well as in customer interest rate swaps and loan syndications. HTLF Specialized Industries also selectively seeks out high quality lending and relationship opportunities within their specific areas of expertise outside our bank markets.

With the oversight of our centralized credit administration group, our credit risk management process is governed by our commercial and consumer loan policies which establish the enterprise framework for credit and underwriting standards across the company. These policies are further governed and supported by our credit risk appetite. Our loan policies establish underwriting standards in alignment with safe and sound credit decision making and in accordance with regulatory guidelines and expectations commensurate with the risk within our portfolio (e.g., Real Estate Lending Standards, Supervisory Loan-to-Value Limits). Centralized staff in credit administration assist our commercial lending officers in the analysis, underwriting of credit, and facilitation of the credit approval process.

In addition to the lending personnel of HTLF Bank, our internal loan review department, which is overseen by the Chief Risk Officer, independently validates credit risk rating accuracy and analyzes credit risk. To reduce the risk of loss, we have

processes to help identify problem loans early, while working with customers and aggressively seeking resolution of credit problems.

As part of Credit Administration, HTLF has a special assets group which focuses on providing guidance to our customers experiencing challenges and resolving problem assets. Loans in a workout status or default are assigned to the special assets group which is also responsible for marketing and disposing of repossessed properties.

Agricultural Banking

We originate loans and build customer relationships in the food, agribusiness and agriculture businesses in our Bank Markets with operations in and around rural areas, including Dubuque Bank & Trust, Premier Valley Bank, Rocky Mountain Bank, Wisconsin Bank & Trust's Monroe and Platteville branches, New Mexico Bank & Trust’s Clovis banking offices, Bank of Blue Valley's northeast Kansas banking offices, and First Bank & Trust. We also have a Food & Agribusiness specialized industry group, which consists of specialized lenders with expert knowledge who focus on loan opportunities to larger commercial agricultural growers, producers and food manufacturers within our Bank Markets, and provide expert knowledge to assist our commercial bankers with loan opportunities. On a selective basis, this specialized industry group seeks out high quality lending and relationship opportunities outside of our bank markets.

Agricultural loans constituted approximately 8% of our total loan portfolio at December 31, 2023. In making agricultural loans, we have policies designating a primary lending area for each Bank, in which most of its agricultural operating and real estate loans are made.

Agricultural loans, many of which are secured by crops, machinery, and real estate, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. Agricultural loans present unique credit risks related to potentially adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products, and the impact of local and federal government regulations. The repayment of agricultural loans also depends upon the profitable operation or management of the agricultural entity.

HTLF has a centralized underwriting group with knowledge and expertise in various types of agricultural lending. The underwriters work closely with lending officers to evaluate credit requests and ensure that underwriting parameters are met in accordance with HTLF's Loan Policy. Further the lending officers of HTLF Bank work closely with their customers to review budgets and cash flow projections for the ensuing crop year. These budgets and cash flow projections are monitored closely during the year and reviewed with the customers at least annually. HTLF Bank also works closely with governmental agencies, including the United States Department of Agriculture ("USDA") and the Farm Services Agency ("FSA"), to help agricultural customers obtain credit enhancement products such as loan guarantees, interest assistance and crop insurance.

Small Business Banking

HTLF's Small Business Lending Center is dedicated to serving the credit needs of small businesses with annual sales generally under $5 million. The Small Business Lending Center is designed to provide quick turnaround on small business customer credit requests related to a wide variety of credit products and services. We believe that small businesses are an underserved market segment and see additional opportunity in serving this market with competitively priced deposit and loan offerings, convenient electronic banking services, and retirement plan services. HTLF Bank has designated business bankers and branch managers to serve the distinct banking needs of these customers.

Residential Real Estate Mortgage Lending

We provide residential real estate mortgage loans to our customers for the purchase or refinancing of single family residential properties. Prior to March 31, 2023, HTLF originated residential mortgage loans through its wholly-owned subsidiary and sold them on the secondary market with servicing retained. On March 31, 2023, HTLF sold its mortgage servicing rights portfolio, which consisted of approximately 4,500 loans serviced for others with an unpaid principal balance of approximately $700 million. Pursuant to the terms of the sale, HTLF's subsidiary provided interim servicing of the loans until the transfer date in May 2023. Following the sale, and because of the decrease in customer demand HTLF elected to significantly scale back mortgage originations, and now offers residential mortgage loans to its customers through the Bank divisions and through a partnership with a third-party mortgage loan provider that began in 2022.

Consumer Banking

A wide variety of consumer banking services are delivered through our branches and electronic banking platforms. Services include checking, savings, money market accounts, certificates of deposit, individual retirement accounts ("IRAs"), certificate of deposit registry service ("CDARS") and debit cards. Consumer lending services include a broad array of consumer loans, including motor vehicle, home improvement, home equity lines of credit ("HELOC"), fixed rate home equity loans and personal lines of credit.

We continue to respond to customer preferences to enhance our consumer banking experience through the addition of secure electronic banking options including online account opening and mobile banking. Our consumer banking customers receive high-touch service in our branches and further enjoy the convenience of online bill pay, 24-hour ATM availability, mobile deposit, and 24-hour access to account detail. As technology advances, we are committed to offering our customers the convenience of online, ATM and mobile delivery channels in a secure manner.

Wealth Management and Retirement Plan Services

HTLF offers wealth management, trust services, brokerage services, and fixed rate annuity products. HTLF also provides retirement plan services to business clients, including 401(k), 403(b) and profit sharing plans. As of December 31, 2023, total trust assets under management were $3.92 billion.

HTLF has contracted with LPL Financial Institution Services, a division of LPL Financial, to operate independent securities brokerage offices at HTLF Bank. Through the LPL Financial third-party arrangement, HTLF offers a full array of investment services including mutual funds, annuities, individual retirement products, education savings products, and brokerage services.

C.  COMPETITION

We face competition for deposits, loans and other financial related services. To compete effectively, grow our market share, maintain flexibility and keep pace with changing client preferences, business and economic conditions, we continuously refine and develop our banking personnel, products and services. We have found the principal methods of competing in the financial services industry are through personal service, expertise, product selection, convenience and technology.

Our Bank Markets are highly competitive, and our competitors include other commercial banks, credit unions, thrifts, fintech firms, stockbrokers, securities and brokerage companies, mutual fund companies, mortgage companies, and insurance companies and other non-bank financial service companies. Some of these competitors are local, while others are regional, national, global, or have no physical location.

Technological advances have made it possible for our competitors, including non-bank competitors, to offer products and services that were traditionally offered exclusively by banks and for financial institutions and other companies to provide electronic and internet-based financial solutions, including online deposit accounts, electronic payment processing and marketplace lending, without having a physical presence where their customers are located. In addition, many of our non-bank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks. In many cases, our competitors have substantially greater resources and lending limits.

We believe we are well-positioned to compete effectively through the array and quality of deposit and credit products and services we provide, and the high-touch, customer-centric way in which we provide them. We invest in our people and we focus on building long-lasting customer relationships through our strategy of serving our customers above and beyond their

expectations through excellence in customer service and providing banking solutions that are tailored to their needs. We believe that our long-standing presence and commitment to the communities we serve and the personal service we emphasize enhance our ability to compete favorably in attracting and retaining commercial and consumer customers. We continue to attract deposit-oriented customers by offering personal attention, combined with convenient electronic banking and other technology-based solutions, professional service and competitive interest rates. The breadth of our product suite, coupled with our superior customer service, allows us to compete favorably with our competitors.

D. HUMAN CAPITAL

People are our most valuable asset. They are critical in providing the high quality of service and knowledge our customers require and deserve. Accordingly, the attraction, retention and promotion of qualified, engaged and diverse employees is critical to HTLF’s success and the growth and preservation of long-term client relationships. HTLF is committed to placing a primary focus on our employees' best interests as part of our evolving human capital strategy. In 2023, we had 91% of employees participate in our annual employee engagement survey, and we achieved our highest average engagement score since inception of the survey process in 2017. On December 31, 2023, HTLF employed 1,970 full-time equivalent employees.

Recruitment and Retention

In response to growing demand for hybrid and remote working options and a tight labor market, we strengthened our employee retention efforts. With the increased demand for talent, we enhanced our recruitment strategies and expanded our recruiting capacity. Given these and other challenges, our net voluntary turnover ratio was 18.1%, and we filled 558 positions, of which approximately 148, or 26.5%, were filled internally. As of December 31, 2023, there were open requisitions for 67 positions, which was a decrease of 21 positions or 31% from 90 open positions at December 31, 2022. We have thoughtfully responded to inflation and other market pressures through increases in compensation.

Employee onboarding and education continue to be delivered virtually, which enables most new hires to be engaged faster to connect with employees beyond just those in their geographic market, and to build their skill set to better serve our customers. HTLF delivers a culture session to all new hires to aid them in understanding the importance of who we are and the importance of living our mission, vision, and values.

Competitive Compensation and Benefits

Aligned with our compensation philosophy, we remain focused on providing market level compensation and benefit packages. We benchmark our compensation programs annually. Incentive arrangements are evaluated annually to ensure that we reward talent appropriately based on performance and for retention purposes, and we have better aligned and improved our market-based pay practices. We believe that there will continue to be upward market adjustments as demands for greater pay transparency increase. We continue to evaluate pay trends, including geographic pay trends and how they impact remote worker pay, to ensure that compensation remains competitive. Approximately 95% of our employees participate in our 401(k) plan, and effective January 1, 2023, we increased the employer match to the plan. We offer an employee stock purchase plan and buy down of student debt in exchange for unused paid time off. We implemented an employee scholarship program supporting secondary education for eligible dependents, as well as a charitable match program for charitable organizations that are important to our team. HTLF organized a company-wide day of service supporting efforts around food insecurity. Employees are also active participants in our wellness platform, which includes a weight loss program, smoking cessation program, a program offering tips on how to stay healthy and resources for home schooling. We offer comprehensive healthcare options including HTLF making annual health savings account contributions.

Investment in Employee Development

We invest in our talent and provide meaningful development opportunities. Our training and education programs start on the employee's first day with the basics of our culture and use of systems. There are more extensive programs for our Commercial and Consumer lending teams that educate them on products, services, sales and systems. Our goal is to help the employee acclimate quickly to HTLF so that they can focus on performing in their roles effectively and provide a superior customer experience. We continue to manage leadership training programs for high potential employees and successors and are increasing our efforts into 2024. All employees participate in our annual computer-based coursework, which includes a suite of human resources and compliance related courses to enhance awareness and understanding. Where appropriate, we also invest in educational and professional certification opportunities for our employees to augment their subject matter expertise.

HTLF has implemented robust education for our consumer and commercial teams to enhance their ability to serve our customers using a value-based approach.

Diversity and Inclusion

HTLF is committed to embracing diversity and inclusion at all levels of the organization beginning with our Board of Directors. Our diversity statement reflects both our current culture and what we aspire to be:

HTLF is unique and so are you. We all come from different backgrounds and experience that help shape our company values. Our values are rooted in the belief that respect, equality, and inclusiveness make us stronger together. The variety of experiences and lifestyles we bring to work every day provides insights that help us better understand each other and our customers.

We publish an annual report showcasing our efforts on Diversity, Equity, and Inclusion ("DEI"), establish metrics in candidate pools and added new Employee Business Resource Groups. We remain committed to offering a series of quarterly speakers on important topics to foster productive dialogue and understanding.

HTLF's Chief Diversity & Inclusion Officer and Diversity Advisory Council were appointed to oversee, advise, and connect DEI activities to a broader business-driven, results-oriented strategy, as well as to align with our corporate values and the future success of HTLF. The Diversity Advisory Council has engaged guest speakers to further the conversation as we work to educate our teams and enhance inclusiveness. We support our employees in building community at HTLF through our employee-driven Employee Business Resource Groups.

E.  SUPERVISION AND REGULATION

General

Financial institutions, their holding companies, and their affiliates are extensively regulated and supervised under federal and state law. As a result, the growth and earnings performance of HTLF may be affected not only by management decisions and general economic conditions, but also by the requirements of federal and state statutes and by the regulations, supervisory expectations and policies of various bank regulatory authorities. Both the scope of the laws and regulations and the intensity of the supervision to which HTLF is subject have increased in recent years because of the increase in HTLF's asset size and other factors such as technological and market changes and banking industry events. Regulatory enforcement and fines have also increased across the banking and financial services sector. Further driven by the banking turmoil in 2023, HTLF expects the scope of regulation and the intensity of supervision will continue to be extensive, including increased scrutiny and higher hurdles for approval of bank mergers and acquisitions by federal bank regulators.

As a bank holding company, HTLF is regulated by the Board of Governors of the Federal Reserve System (the "Federal Reserve"). HTLF Bank is regulated by the FDIC as its principal federal regulator and the Colorado Department of Regulatory Agencies, Division of Banking (the "Colorado Division of Banking") as its state regulator.

Federal and state laws and regulations generally applicable to financial institutions regulate, among other things, the scope of business, the kinds and amounts of investments, reserve requirements, capital levels, the establishment of branches, mergers and consolidations, and the payment of dividends. This system of supervision and regulation establishes a comprehensive framework for the respective operations of HTLF and its subsidiaries and is intended primarily for the protection of the FDIC-insured deposits and depositors, consumers, the stability of the financial system in the United States, and the health of the national economy, rather than stockholders.

Federal and state banking regulators regularly examine HTLF and HTLF Bank to evaluate their financial condition and monitor their compliance with laws and regulatory policies. Following those exams, HTLF and HTLF Bank are assigned supervisory ratings. These ratings are considered confidential supervisory information and disclosure to third parties is not allowed without permission of the issuing regulator. Violations of laws and regulations or deemed deficiencies in risk management practices may be incorporated into these supervisory ratings. A downgrade in these ratings could limit HTLF’s ability to pursue acquisitions or conduct other expansionary activities for a period of time, require new or additional regulatory approvals before engaging in certain other business activities or investments, affect HTLF Bank's deposit insurance assessment rate, and impose additional recordkeeping and corporate governance requirements, as well as generally increase regulatory scrutiny of HTLF.

The federal banking agencies have broad authority to issue orders to depository institutions and their holding companies prohibiting activities that constitute violations of law, rule, regulation, or administrative order, or that represent unsafe or unsound banking practices, as determined by the federal banking agencies. The federal banking agencies also are empowered to require affirmative actions to correct any violation or practice; issue administrative orders that can be judicially enforced; direct increases in capital; limit dividends and distributions; restrict growth; assess civil money penalties against institutions or individuals who violate any laws, regulations, orders, or written agreements with the agencies; order termination of certain activities of holding companies or their non-bank subsidiaries; remove officers and directors; order divestiture of ownership or

control of a non-banking subsidiary by a holding company; or terminate deposit insurance and appoint a conservator or receiver.

The CFPB has broad rulemaking authority over a wide range of federal consumer protection laws applicable to our business. We are subject to CFPB examination and supervision relating to compliance with federal consumer protection laws and regulations. Any non-bank subsidiaries are subject to regulation by their functional regulators, including applicable state finance and insurance agencies.

Banking and other financial services statutes, regulations and policies are continually under review by Congress, state legislatures and federal and state regulatory agencies. In addition to laws and regulations, state and federal bank regulatory agencies may issue policy statements, interpretive letters and similar written guidance applicable to HTLF and its subsidiaries. Any change in the statutes, regulations or regulatory policies, including changes in their interpretation or implementation, may have a material effect on our business.

This section summarizes material elements of the regulatory framework that applies to HTLF and HTLF Bank. It does not describe all applicable statutes, regulations and regulatory policies that apply, nor does it disclose all the requirements of the statutes, regulations and regulatory policies requirements that are described.

Regulation of HTLF

General

HTLF, as the sole shareholder of HTLF Bank, is a bank holding company. As a bank holding company, HTLF is registered with, and is subject to regulation, supervision and examination by, the Federal Reserve under the BHCA. In accordance with Federal Reserve policy, HTLF is expected to act as a source of financial and managerial strength to HTLF Bank and to commit resources to support HTLF Bank in circumstances where HTLF might not otherwise do so. Under the Dodd-Frank Act, the FDIC also has backup enforcement authority over a depository institution holding company, such as HTLF, if the conduct or threatened conduct of the holding company poses a risk to the Deposit Insurance Fund, although such authority may not be used if the holding company is in sound condition and does not pose a foreseeable and material risk to the insurance fund.

Under the BHCA, HTLF is subject to examination by the Federal Reserve. Supervision and examinations are confidential, and the outcomes of these actions will not be made public. HTLF is also required to file periodic reports with the Federal Reserve of HTLF's operations and such additional information regarding HTLF and its subsidiaries as the Federal Reserve may require.

Bank holding companies that meet certain eligibility requirements prescribed by the BHCA may elect to operate as financial holding companies which may engage in, or own shares in companies engaged in, a wider range of nonbanking activities. As of the date of this Annual Report on Form 10-K, HTLF has not applied for approval to operate as a financial holding company.

Acquisitions, Activities and Change in Control

Acquisitions of HTLF’s voting stock above certain thresholds may be subject to prior regulatory notice or approval under applicable federal banking laws. Investors are responsible for ensuring that they do not, directly or indirectly, acquire shares of our stock in excess of the amount that can be acquired without regulatory approval or notice under the BHCA and the Change in Bank Control Act.

The BHCA generally requires the prior approval of the Federal Reserve before acquiring direct or indirect ownership or control of more than 5% of the voting shares of a bank or bank holding company, or merging or consolidating with another bank holding company. The Bank Merger Act generally requires us to obtain prior regulatory approval to merge, consolidate with, acquire substantially all the assets of, or assume deposits of another bank.

Capital Requirements

Bank holding companies and their subsidiary financial institutions are required to maintain minimum risk-based and leverage capital ratios, as well as a capital conservation buffer, pursuant to regulations adopted by the Federal Reserve and FDIC, as applicable, to implement the Basel III capital framework ("Basel III Rule"). These requirements include quantitative measures that assign risk weightings to assets and off-balance sheet items and define and set minimum regulatory capital ratios. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional discretionary, actions by the federal banking regulators that, if undertaken, could have a material adverse effect on the financial condition and results of operations of a bank holding company and its subsidiaries. Federal banking regulators are required by law to take prompt action when institutions are viewed as engaging in unsafe or unsound practices or do not meet certain minimum capital requirements. In addition to other potential actions, failure to meet regulatory capital requirements would result in limitations on capital distributions as well as executive bonuses. The Federal Reserve, FDIC and applicable state banking regulators may determine

that a banking organization, based on its size, complexity or risk profile must maintain a higher level of capital in order to operate in a safe and sound manner.

The regulations of the Federal Reserve and the FDIC as the primary regulator of state banks, separate capital into three components, Common Equity Tier 1 ("CET 1") capital, Tier 1 capital and Tier 2 capital, and test these capital components based on their ratio to assets and to "risk weighted assets." CET 1 capital consists of common stockholders' equity. Tier 1 capital generally consists of (a) common stockholders' equity, qualifying noncumulative preferred stock, and to the extent they do not exceed 25% of total Tier 1 capital, qualifying cumulative perpetual preferred stock and, for some institutions, trust preferred securities, and (b) among other things, goodwill and specified intangible assets, credit enhancing strips and investments in unconsolidated subsidiaries. Tier 2 capital includes, to the extent not in excess of Tier 1 capital, the allowance for credit losses, other qualifying perpetual preferred stock, certain hybrid capital instruments, qualifying term subordinated debt and certain trust preferred securities not otherwise included in Tier 1 capital. Risk weighted assets include the sum of specific assets of an institution multiplied by risk weightings for each asset class.

The Basel III Rule generally requires that CET 1 capital include the effects of other comprehensive income adjustments, such as gains and losses on securities held to maturity, but allow institutions, such as HTLF, to make a one-time election not to include those effects. HTLF and HTLF Bank elected not to include the effects of other comprehensive income in CET 1 capital.

Under the Basel III Rule, HTLF and HTLF Bank are required to comply with a leverage requirement consisting of a minimum ratio of Tier 1 capital to total assets (the "Leverage Ratio") of 4.0%. The Basel III Rule also requires HTLF and HTLF Bank to maintain a capital conservation buffer composed entirely of common equity Tier 1 capital of 2.5% in addition to the minimum risk-weighted asset ratios designed to absorb losses during periods of economic stress.

The following table presents the minimum regulatory capital ratios, minimum ratio plus capital conservation buffer, and well-capitalized minimums that HTLF and HTLF Bank must satisfy.

Ratio	Entity	Minimum Regulatory Capital Ratio %	Minimum Ratio + Capital Buffer %(1)	Well-Capitalized Minimum %(2)
CET 1 risk-based capital	Consolidated	4.50	7.00	N/A
	Bank	4.50	7.00	6.50
Tier 1 risk-based capital	Consolidated	6.00	8.50	6.00
	Bank	6.00	8.50	8.00
Total risk-based capital	Consolidated	8.00	10.50	10.00
	Bank	8.00	10.50	10.00
Tier 1 leverage ratio	Consolidated	4.00	N/A	N/A
	Bank	4.00	N/A	5.00
(1) Reflects a capital conservation buffer of 2.5%
(2) Reflects the well-capitalized standard applicable to HTLF under Federal Reserve Regulation Y and the well-capitalized standard applicable to HTLF Bank.

Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our operations or financial condition. For example, a financial institution generally must be "well-capitalized" to engage in acquisitions, and well-capitalized institutions may qualify for exemptions from prior notice or application requirements otherwise applicable to certain types of activities and may qualify for expedited processing of other required notices or applications. In addition, only a well-capitalized depository institution may accept brokered deposits without prior regulatory approval. Failure to be well-capitalized or to meet minimum capital requirements could also result in restrictions on HTLF’s or HTLF Bank's ability to pay dividends or otherwise distribute capital. As part of its risk management framework, HTLF performs on-going capital stress testing to validate its capital resiliency and ability to meet internal and regulatory capital thresholds under normal and stressed scenarios. The results of stress tests are leveraged and further inform on strategic and capital planning activities. See the discussion of "Capital Resources" in Management’s Discussion and Analysis of Financial Condition and Results of Operations. As of December 31, 2023, HTLF had regulatory capital in excess of the Federal Reserve requirements for well-capitalized bank holding companies.

Climate-Related Risk Management and Regulation

In recent years the federal banking agencies have increased their focus on climate-related risks impacting the operations of banks, the communities they serve and the broader financial system. For example, in 2021, the Financial Stability Oversight Council published a report identifying climate-related financial risks as an “emerging threat” to financial stability, and on October 24, 2023, the OCC, the FDIC and the Federal Reserve jointly finalized principles for climate-related financial risk management for national banks with more than $100 billion in total assets. Although these risk management principles do not apply to HTLF, as climate-related supervisory guidance is formalized, and relevant risk areas and corresponding control expectations are further refined, we may be required to expend significant capital and incur compliance, operating, maintenance and remediation costs in order to conform to such requirements.

In addition, climate disclosure rules have been or are being enacted by states and the SEC. In October 2023, California enacted two climate-related disclosure laws. The Climate Corporate Data Accountability Act (referred to as SB 253) requires all U.S. businesses with revenues greater than $1 billion doing business in California to report their greenhouse gas emissions, including scopes 1, 2, and 3, beginning in 2026 (for 2025 data), and also requires reporting companies to get third-party assurance of their reports. Other states have proposed similar legislation to SB 253. The Climate-Related Financial Risk Act (referred to as SB 261) requires U.S. businesses with annual revenues over $500 million doing business in California to bi-annually disclose climate-related financial risks and their mitigation strategies beginning January 1, 2026. In addition, in March of 2022, the SEC proposed new climate-related disclosure rules. If adopted as expected, the rules would require new climate-related disclosures in SEC filings and audited financial statements, including certain climate-related metrics and greenhouse gas emissions data, information about climate-related targets and goals, transition plans, if any, and attestation requirements.

Dividend Payments

HTLF's ability to pay dividends to its stockholders may be affected by general corporate law considerations, minimum regulatory capital requirements, and policies of the Federal Reserve applicable to bank holding companies. As a Delaware corporation, HTLF is subject to the limitations of the Delaware General Corporation Law (the "DGCL"), which allows HTLF to pay dividends only out of its surplus (as defined and computed in accordance with the provisions of the DGCL) or, if HTLF has no such surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year. Federal Reserve policy provides that a bank holding company should not pay cash dividends unless (1) its net income over the last four quarters (net of dividends paid) is sufficient to fully fund the dividends, (2) the prospective rate of earnings retention appears consistent with the capital needs, asset quality, and overall financial condition of the bank holding company and its subsidiaries, and (3) the bank holding company will continue to meet minimum required capital adequacy ratios. The policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid, or that could result in a material adverse change to the bank holding company’s capital structure. Bank holding companies also are expected to consult with the Federal Reserve before materially increasing dividends. The Federal Reserve could prohibit or limit the payment of dividends by HTLF if it determines that payment of the dividend would constitute an unsafe or unsound practice.

Regulation of HTLF Bank

General

HTLF Bank is a Colorado state-chartered, non-member bank, which means it was formed under state law and is not a member of the Federal Reserve System. As a result, HTLF Bank is subject to the direct regulation, examination, supervision, and reporting and enforcement requirements of the Colorado Division of Banking, the chartering authority for Colorado banks, as well as by the FDIC as its primary federal banking regulator.

Deposit Insurance

The deposits of HTLF Bank are insured by the Depositors Insurance Fund (“DIF”) up to the standard maximum deposit insurance amount of $250,000 per depositor. As an FDIC-insured institution, HTLF Bank is required to pay deposit insurance premium assessments to the FDIC using a risk-based assessment system based upon average total consolidated assets minus tangible equity of the insured bank. The FDIC has authority to raise or lower assessment rates on insured deposits in order to achieve statutorily required reserve ratios in the DIF and to impose special additional assessments. On October 18, 2022, the FDIC finalized a rule that increased the initial base deposit insurance assessment rates by 2 basis points, beginning with the first quarterly assessment period of 2023.

In November 2023, the FDIC approved a final rule imposing a special assessment on banks to recover losses in connection with its decision to guarantee uninsured deposits at two failed banks in March 2023. The rule provides for a 13.44 basis point annual special assessment on the uninsured deposits of a bank as of December 31, 2022, excluding the first $5 billion of uninsured deposits. The special assessment will be payable quarterly, and will be collected for an estimated eight quarters. At December

31, 2022, HTLF's uninsured deposits were $8.03 billion. As a result, HTLF Bank recorded an $8.145 million additional FDIC assessment expense in the fourth quarter of 2023 which was the full amount of the special assessment.

Supervisory Assessments

HTLF Bank is required to pay supervisory assessments to the Colorado Division of Banking to fund the operations of that agency. In general, the amount of the assessment is calculated based on each institution's total assets. During 2023, HTLF Bank paid supervisory assessments totaling $954,000 to the Colorado Division of Banking and to the other state regulators prior to merging HTLF's other banking subsidiaries into HTLF Bank.

Prompt Corrective Action

The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA") requires the federal bank regulatory agencies to take "prompt corrective action" regarding FDIC-insured depository institutions that do not meet certain capital adequacy standards. A depository institution’s treatment for purposes of the prompt corrective action provisions depends upon its level of capitalization and certain other factors. An institution that fails to remain well-capitalized becomes subject to a series of restrictions that increase in severity as its capital condition weakens. Such restrictions may include a prohibition on capital distributions, restrictions on asset growth or restrictions on the ability to receive regulatory approval of applications. The FDICIA also provides for enhanced supervisory authority over undercapitalized institutions, including authority for the appointment of a conservator or receiver for the institution. In certain instances, a bank holding company may be required to guarantee the performance of an undercapitalized subsidiary bank’s capital restoration plan. The capital adequacy requirements applicable to HTLF Bank are described above under the caption "HTLF-Capital Requirements."

As of December 31, 2023: (i) HTLF Bank was not subject to a directive from its primary federal regulator to increase its capital; (ii) HTLF Bank exceeded its minimum regulatory capital requirements under applicable capital adequacy guidelines; (iii) HTLF Bank was "well-capitalized," as defined by applicable regulations; and (iv) HTLF Bank was not subject to a directive to maintain capital higher than the regulatory capital requirements, as discussed below under the caption "Safety and Soundness Standards."

Liability of Commonly Controlled Institutions

Under federal law, institutions insured by the FDIC may be liable for any loss incurred by, or reasonably expected to be incurred by, the FDIC in connection with the default of commonly controlled FDIC-insured depository institutions or any assistance provided by the FDIC to commonly controlled FDIC-insured depository institutions in danger of default. Because HTLF controls HTLF Bank, HTLF Bank is commonly controlled for purposes of these provisions of federal law.

Anti-Money Laundering

A major focus of governmental policy on financial institutions in recent years has been aimed at combating money laundering and terrorist financing. The Bank Secrecy Act, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (the "USA PATRIOT Act") and other related federal laws and regulations require financial institutions, including HTLF Bank, to implement policies and procedures relating to anti-money laundering, customer identification and due diligence requirements and the reporting of certain types of transactions and suspicious activity. The Financial Crimes Enforcement Network rules require financial institutions to develop policies, procedures and practices to prevent and deter money laundering. The program must be a written board-approved program that is reasonably designed to identify and verify the identities of beneficial owners of legal entity customers at the time a new account is opened. The program must, at a minimum (1) provide for a system of internal controls to assure ongoing compliance; (2) designate a compliance officer; (3) establish an ongoing employee training program; and (4) implement an independent audit function to test programs. Financial institutions are also prohibited from entering into specified financial transactions and account relationships and must use enhanced due diligence procedures in their dealings with certain types of high-risk customers and implement a written customer identification program. Financial institutions must take certain steps to assist government agencies in detecting and preventing money laundering and report certain types of suspicious transactions.

The Anti-Money Laundering Act of 2020 (“AMLA”), which amends the Bank Secrecy Act of 1970 (“BSA”), was enacted in January 2021. The AMLA is intended to be a comprehensive reform and modernization to U.S. bank secrecy and anti-money laundering laws. Among other things, it codifies a risk-based approach to anti-money laundering compliance for financial institutions; requires the U.S. Department of the Treasury to promulgate priorities for anti-money laundering and countering the financing of terrorism policy; requires the development of standards for testing technology and internal processes for BSA compliance; expands enforcement- and investigation-related authority, including increasing available sanctions for certain BSA violations; and expands BSA whistleblower incentives and protections. Many of the statutory provisions in the AMLA will require additional rulemaking, reports and other measures, and the impact of the AMLA will depend on, among other things, rulemaking and implementation guidance. In June 2021, the Financial Crimes Enforcement Network, a bureau of the U.S.

Department of the Treasury, issued the priorities for anti-money laundering and countering the financing of terrorism policy required under the AMLA. The priorities include corruption, cybercrime, terrorist financing, fraud, transnational crime, drug trafficking, human trafficking and proliferation financing.

Office of Foreign Assets Control Regulation

The U.S. Department of the Treasury’s Office of Foreign Assets Control, or "OFAC," is responsible for administering economic sanctions that affect transactions with designated foreign countries, nationals and others, as defined by various Executive Orders and Acts of Congress. OFAC-administered sanctions take many different forms. For example, sanctions may include: (1) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on U.S. persons engaging in financial transactions relating to, making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (2) a blocking of assets in which the government or "specially designated nationals" of the sanctioned country have an interest, by prohibiting transfers of property subject to U.S. jurisdiction (including property in the possession or control of U.S. persons). OFAC also publishes lists of persons, organizations, and countries suspected of aiding, harboring or engaging in terrorist acts, known as Specially Designated Nationals and Blocked Persons. Blocked assets (e.g., property and bank deposits) cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences.

Dividend Payments

HTLF Bank is a legal entity separate and distinct from HTLF. The primary source of funds for HTLF is dividends from HTLF Bank. In general, HTLF Bank may only pay dividends either out of net income after any required transfers to surplus or reserves have been made or out of retained earnings.

The payment of dividends by any financial institution is limited by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. As described above, HTLF Bank exceeded its minimum capital requirements under applicable guidelines as of December 31, 2023.

As of December 31, 2023, approximately $436.9 million was available in retained earnings at HTLF Bank for payment of dividends to HTLF under the regulatory capital requirements to remain well-capitalized. Notwithstanding the availability of funds for dividends, however, the FDIC and state regulators may reduce or prohibit the payment of dividends by HTLF Bank.

Transactions with Affiliates

The Federal Reserve regulates transactions among HTLF and its subsidiaries. Generally, the Federal Reserve Act and Regulation W, as amended by the Dodd-Frank Act, limit lending and certain other Covered Transactions as well as other transactions between HTLF Bank and its affiliates, including HTLF, for the primary purpose of protecting the interests of HTLF Bank. The aggregate amount of Covered Transactions HTLF Bank may enter into with an affiliate may not exceed 10% of the capital stock and surplus of HTLF Bank, and the aggregate amount of "covered transactions" with all affiliates may not exceed 20% of the capital stock and surplus of HTLF Bank.

Covered Transactions between HTLF Bank and its affiliates are also subject to collateralization requirements and must be conducted on arm’s length terms. "Covered Transactions" with respect to an affiliate means: (a) an extension of credit to the affiliate; (b) a purchase of, or an investment in, a security issued by the affiliate; (c) a purchase of an asset from the affiliate, including assets subject to recourse or repurchase except as otherwise exempted by the Federal Reserve, (d) the acceptance of a security issued by the affiliate as collateral for an extension of credit; and (e) the issuance of a guarantee, acceptance or letter of credit on behalf of the affiliate, a confirmation of a letter of credit issued by the affiliate, and cross-affiliate netting arrangement.

Insider Transactions

HTLF Bank is subject to certain restrictions imposed by federal law on extensions of credit to HTLF and its subsidiaries, on investments in the stock or other securities of HTLF and its subsidiaries and the acceptance of the stock or other securities of HTLF or its subsidiaries as collateral for loans made by HTLF Bank. Certain limitations and reporting requirements are also placed on extensions of credit by HTLF Bank to its directors and officers, to directors and officers of HTLF and its subsidiaries, to principal stockholders of HTLF and to "related interests" of such directors, officers and principal stockholders. In addition, federal law and regulations provide certain restrictions on the terms upon which any person who is a director or officer of HTLF or any of its subsidiaries or a principal stockholder of HTLF that may obtain credit from banks with which HTLF Bank maintains correspondent relationships.

Safety and Soundness Standards

The federal banking agencies have adopted guidelines that establish operational and managerial standards to promote the safety and soundness of federally insured depository institutions. The guidelines set forth standards for internal controls, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, risk management, vendor and model risk management, asset quality and earnings. In general, the safety and soundness guidelines prescribe the goals to be achieved in each area, and each institution is responsible for establishing its own procedures to achieve those goals. If an institution fails to comply with any of the standards set forth in the guidelines, the institution's primary federal regulator may require the institution to submit a plan for achieving and maintaining compliance. If an institution fails to submit an acceptable compliance plan or fails in any material respect to implement a compliance plan that has been accepted by its primary federal regulator, the regulator is required to issue an order directing the institution to cure the deficiency. Until the deficiency cited in the regulator's order is cured, the regulator may restrict the institution's rate of growth, require the institution to increase its capital, restrict the rates the institution pays on deposits or require the institution to take any action the regulator deems appropriate under the circumstances. Noncompliance with the standards established by the safety and soundness guidelines may also constitute grounds for other enforcement action by the federal banking regulators, including cease and desist orders and civil money penalty assessments.

Properly managing risks has been identified as critical to the conduct of safe and sound banking activities and has become even more important as new technologies, product innovation, reliance on third-party application, and the size and speed of financial transactions have changed the nature of banking markets. The federal banking agencies have identified a spectrum of risks facing banking institutions including, but not limited to, credit, market, liquidity, operational, legal, and reputational risk. Some of the regulatory pronouncements have focused on operational risk, which arises from the potential that inadequate information systems, operational problems, breaches in internal controls, fraud, or unforeseen catastrophes will result in unexpected losses. New products and services, third-party risk management, fraud and cybersecurity are critical sources of operational risk that financial institutions are expected to address in the current environment. HTLF Bank is expected to have active board and senior management oversight; adequate policies, procedures, and limits; adequate risk measurement, monitoring, and management information systems; and comprehensive and effective internal controls.

Interstate Branching and Bank Merger Authority

Pursuant to the Dodd-Frank Act, state-chartered banks may open an initial branch in a state other than its home state by establishing a de novo branch at any location in such host state at which a bank chartered in such state could establish a branch. Applications to establish such branches must still be approved by the appropriate primary federal regulator.

Federal law permits state and national banks to merge with banks in other states subject to: (i) regulatory approval; (ii) federal and state deposit concentration limits; and (iii) state law limitations requiring the merging bank to have been in existence for a minimum period of time (not to exceed five years) prior to the merger.

State Bank Investments and Activities

HTLF Bank generally is permitted to make investments and engage in activities directly or through subsidiaries as authorized by the laws of the state of Colorado. However, under federal law and FDIC regulations, FDIC-insured state banks are prohibited, subject to certain exceptions, from making or retaining equity investments of a type, or in an amount, that are not permissible for a national bank. Federal law and FDIC regulations also prohibit FDIC-insured state banks and their subsidiaries, subject to certain exceptions, from engaging as principal in any activity that is not permitted for a national bank, unless the bank meets, and continues to meet, its minimum regulatory capital requirements and the FDIC determines the activity would not pose a significant risk to the deposit insurance fund of which the bank is a member.

Incentive Compensation Policies and Restrictions

The federal banking agencies have issued joint guidance on incentive compensation designed to ensure that the incentive compensation policies of banking organizations such as HTLF and HTLF Bank are consistent with the safety and soundness of the organization and its subsidiary banks.

In addition, the Dodd-Frank Act requires the federal banking agencies and the SEC to issue regulations and guidelines requiring covered banking organizations such as HTLF and HTLF Bank, to prohibit incentive-based compensation payment arrangements that encourage inappropriate risk taking by providing compensation that is excessive or that could lead to material financial loss to the organization. Proposed joint rules were issued in 2011 and 2016, and the SEC has indicated that they intend to complete the rulemaking process in 2024. In 2023, the SEC approved Nasdaq's listing standard requiring listed companies to implement clawback policies to recover incentive-based compensation from current or former executive officers in the event of certain financial restatements and would also require companies to disclose their clawback policies and their actions under those policies. Pursuant to this listing standard, listed companies had until December 1, 2023 to adopt compliant clawback policies. HTLF has adopted a clawback policy, which is filed as Exhibit 97 to this Annual Report of Form 10-K.

The Volcker Rule and Proprietary Trading

HTLF and HTLF Bank are prohibited under the Volcker Rule from (1) engaging in short-term proprietary trading for their own accounts, and (2) having certain ownership interests in and relationships with hedge funds or private equity funds. The fundamental prohibitions of the Volcker Rule apply to banking entities of any size, including HTLF and HTLF Bank. The Volcker Rule regulations contain exemptions for market-making, hedging, underwriting, trading in U.S. government and agency obligations and also permit certain ownership interests in certain types of funds to be retained. They also permit the offering and sponsoring of funds under certain conditions. The Volcker Rule regulations impose compliance and reporting obligations on banking entities.

Community Reinvestment Act Requirements

The Community Reinvestment Act ("CRA") imposes a continuing and affirmative obligation on HTLF Bank to help meet the credit needs of the communities in which it does business, including low- and moderate-income neighborhoods, in a safe and sound manner. The FDIC and the state regulators regularly assess the record of HTLF Bank in meeting the credit needs of the communities in which it does business. Applications for additional acquisitions are subject to evaluation of the effectiveness of HTLF Bank in meeting its CRA requirements.

In May 2022, the FDIC, Office of the Comptroller of the Currency ("OCC") and the Federal Reserve issued a joint Notice of Proposed Rulemaking ("NPR") on the Community Reinvestment Act. The NPR is intended to strengthen and modernize the rule that implements the CRA by expanding access to credit, investment and banking services in low- and moderate- income ("LMI") communities, which are CRA's core goals; adapting to changes in the banking industry, including mobile and internet banking by modernizing assessment areas while remaining focused on branch-based communities; providing greater clarity, consistency, and transparency in the application of the regulations through the use of standardized metrics as part of CRA evaluation and clarification eligible CRA activities focused on LMI communities and under-served rural communities; tailoring of CRA rules and data collection to bank size and business model and maintaining a unified approach among the regulators. The proposed rule contains expanded data collection and reporting requirements for which the impact and associated costs are unknown. Effective October 2023, the FDIC, OCC and the Federal Reserve issued the final CRA rule with the objective of updating the CRA regulations to strengthen the core purpose of the statute, and adapt to changes in the banking industry, including the expanded role of mobile and online banking. Most of the final rule's requirements will go into effect on January 1, 2026.

Consumer Protection

HTLF Bank is subject to a variety of federal and state statutes and regulations designed to protect consumers and is also under the supervision of the Consumer Financial Protection Bureau (CFPB), a federal agency responsible for implementing, examining, and enforcing compliance with federal consumer protection laws. The CFPB has broad rulemaking authority over a wide range of federal consumer protection laws that apply to banks and other providers of financial products and services, including among other things fair lending laws and the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB can issue cease-and-desist orders against banks and other entities that violate consumer financial laws. The CFPB may also institute a civil action against an entity in violation of federal consumer financial law in order to impose a civil penalty or injunction. The CFPB has examination and enforcement authority over all banks with more than $10 billion in assets, as well as their affiliates. Banking regulators take into account compliance with consumer protection laws when considering approval of a proposed transaction. In addition, state attorneys general and other state officials have authority to enforce consumer protection rules issued by the CFPB. State authorities have recently increased their focus on and enforcement of consumer protection rules.

The CFPB also publishes complaints submitted by consumers regarding consumer financial products and services in a publicly accessible online portal. The CFPB publishes complaint narratives from consumers that opted to have their narratives made public. The CFPB may use published complaint narratives to make decisions regarding regulatory, enforcement or examination issues, and the publication of such narratives may have a negative effect on the reputation of those institutions that are the subject of complaints.

In March 2023, the CFPB issued a final rule amending Regulation B to implement changes to the Equal Credit Opportunity Act made by Section 1071 of the Dodd-Frank Act. Under the final rule, covered financial institutions are required to collect and report to the CFPB data on applications for credit for small businesses, including those that are owned by women and minorities. The purpose of Section 1071 is to facilitate enforcement of fair lending laws and to enable communities, governmental entities and creditors to identify business and community development needs and opportunities for women-owned, minority owned, and small businesses. The American Bankers Association (ABA) and the Texas Bankers Association (TBA) challenged the CFPB's final rule in Federal district court, and on July 31, 2023, the district court stayed the rule’s mandatory compliance dates for banks that are members of ABA and/or TBA. The stay was granted until the Supreme Court

decides whether the CFPB's funding structure is constitutional in Community Financial Services Association of America v. CFPB. The district court ordered the CFPB to extend the 1071 final rule's mandatory compliance dates, once the Supreme Court rules, by the number of months that elapse from July 31 to the date the Supreme Court rules. The Supreme Court is expected to rule during the first half of 2024.

In addition, deposit operations are subject to, among others: the Truth in Savings Act and Regulation DD issued by the CFPB, which require disclosure of deposit terms to consumers; Regulation CC issued by the Federal Reserve Board, which relates to the availability of deposit funds to consumers; the Right to Financial Privacy Act, which imposes a duty to maintain the confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records; and the Electronic Fund Transfer Act and Regulation E issued by the CFPB, which governs automatic deposits to and withdrawals from deposit accounts and customers’ rights and liabilities arising from the use of automated teller machines and other electronic banking services.

Mortgage Lending

Mortgage loans originated by or held at HTLF Bank are subject to a number of laws and rules affecting residential mortgages, including the Home Mortgage Disclosure Act ("HMDA") and Regulation C and the Real Estate Settlement Procedures Act ("RESPA"), Regulation X and rules regarding the mandatory purchase of flood insurance, including those issued pursuant to the Biggert-Waters Flood Insurance Reform Act. In recent years, the CFPB and other federal agencies have proposed and finalized a number of rules affecting residential mortgages. These rules implement the Dodd-Frank Act amendments to the Equal Credit Opportunity Act, Truth in Lending Act ("TILA") and RESPA. The rules, among other things, impose requirements regarding procedures to ensure compliance with the "ability to repay" requirements further detailed below, policies and procedures for servicing mortgages, and additional rules and restrictions regarding mortgage loan originator compensation and qualification and registration requirements for individual loan originator employees. These rules also impose new or revised disclosure requirements, including a new integrated mortgage origination disclosure that combines disclosures currently required under TILA and RESPA.

HMDA and Regulation C require lenders to report certain information regarding home loans, and includes tests for determining what financial institutions and credit transactions are covered under HMDA and reporting requirements for new data points identified in the Dodd-Frank Act or identified by the CFPB as necessary to carry out the purposes of HMDA. Regulation C requires detailed information from lenders and the reporting on mortgage loan underwriting and pricing.

Ability-to-Repay and Qualified Mortgage Rule

Under Federal Reserve Board Regulation Z, a mortgage lender is required to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms. Mortgage lenders are required to determine consumers’ ability to repay in one of two ways. The first alternative requires the mortgage lender to consider the following eight underwriting factors when making the credit decision: (1) current or reasonably expected income or assets; (2) current employment status; (3) the monthly payment on the covered transaction; (4) the monthly payment on any simultaneous loan; (5) the monthly payment for mortgage-related obligations; (6) current debt obligations, alimony and child support; (7) the monthly debt-to-income ratio or residual income; and (8) credit history. Alternatively, the mortgage lender can originate "qualified mortgages," which are entitled to a presumption that the creditor making the loan satisfied the ability-to-repay requirements. In general, a "qualified mortgage" is a mortgage loan without negative amortization, interest-only payments, balloon payments or terms exceeding 30 years. In addition, to be a qualified mortgage, the points and fees paid by a consumer cannot exceed 3% of the total loan amount. Qualified mortgages that are "higher-priced" (e.g., subprime loans) have a rebuttable presumption of compliance with the ability-to-repay rules, while qualified mortgages that are not "higher-priced" (e.g., prime loans) are given a safe harbor of compliance. HTLF Bank primarily originates compliant qualified mortgages.

Lending Standards and Guidance

The federal banking agencies have adopted uniform regulations prescribing standards for extensions of credit that are secured by liens or interests in real estate or made for the purpose of financing permanent improvements to real estate. Under these regulations, all insured depository institutions, such as HTLF Bank, must adopt and maintain written policies establishing appropriate limits and standards for extensions of credit that are secured by liens or interests in real estate or are made for the purpose of financing permanent improvements to real estate. These policies must establish loan portfolio diversification standards, prudent underwriting standards (including loan-to-value limits) that are clear and measurable, loan administration procedures, and documentation, approval and reporting requirements. The real estate lending policies must reflect consideration of the federal bank regulators’ Interagency Guidelines for Real Estate Lending Policies.

Data Privacy and Cybersecurity

Various federal and state laws and regulations contain extensive data privacy and cybersecurity provisions and the regulatory framework for data privacy and cybersecurity is evolving rapidly. At the federal level, the Gramm-Leach-Bliley Act ("GLBA") requires financial institutions to, among other things, periodically disclose their privacy policies and practices relating to sharing personal information and, in some cases, enables consumers to opt out of the sharing of certain information with unaffiliated third parties. The GLBA also requires financial institutions to implement an information security program that includes administrative, technical and physical safeguards to ensure the security and confidentiality of customer records and information, which is assessed annually and reviewed on an ongoing basis by the Board of Directors. Additionally, like other lenders, HTLF Bank uses credit bureau data in their underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act ("FCRA"), and the FCRA also regulates reporting information to credit bureaus, prescreening individuals for credit offers, sharing of information between affiliates, and using affiliate data for marketing purposes. HTLF is also subject to the rules and regulations promulgated under the authority of the Federal Trade Commission, which regulates unfair or deceptive acts or practices, including with respect to data privacy and cybersecurity. In addition, the United States Congress may enact more comprehensive data privacy and cybersecurity legislation.

The federal banking regulators, as well as the SEC and related self-regulatory organizations, regularly issue guidance regarding cybersecurity that is intended to enhance cyber risk management among financial institutions. A financial institution is expected to (i) establish a framework of internal control, first, second and third lines of defense, and risk management policies, procedures and processes that are designed to address the cyber risks that it faces in its business operations; (ii) maintain sufficient business continuity planning processes to ensure the rapid recovery, resumption and maintenance of the institution’s operations after a cyber-attack; and (iii) develop appropriate processes to enable recovery of data and business operations if the institution or its critical service providers fall victim to a cyber-attack. The Federal Financial Institutions Examination Council ("FFIEC") developed the Cybersecurity Assessment Tool to help financial institutions identify their risks and determine their preparedness for cybersecurity threats. The FFIEC has also issued an Information Security booklet, which includes guidelines for evaluating the adequacy of information security programs (including effective threat identification, assessment and monitoring, and incident identification assessment and response), assurance reports and testing of information security programs.

Under a final rule adopted by federal banking agencies in 2021, banking organizations are required to notify their primary banking regulator within 36 hours of determining that a “computer-security incident” has materially disrupted or degraded, or is reasonably likely to materially disrupt or degrade, the banking organization’s ability to carry out banking operations or deliver banking products and services to a material portion of its customer base, its businesses and operations that would result in material loss, or its operations that would impact the stability of the United States. In 2023, the SEC issued a final rule that requires disclosure of material cybersecurity incidents, as well as cybersecurity risk management, strategy and governance. Under this rule, banking organizations that are SEC registrants must generally disclose information about a material cybersecurity incident within four business days of determining it is material with periodic updates as to the status of the incident in subsequent filings as necessary.

Data privacy and cybersecurity are also areas of increasing state legislation. Various state laws and regulations apply, or may apply in the future, to HTLF’S operations and may impose additional requirements on HTLF and its subsidiaries or otherwise impact HTLF’s ability to share certain personal information with affiliates and non-affiliates. For example, the California Consumer Protection Act of 2018 (the "CCPA") gives California residents the right to, among other things, request disclosure of information collected about them and whether that information has been sold to others, request deletion of personal information (subject to certain exceptions), opt out of the sale of their personal information, and not be discriminated against for exercising these rights. In addition, the California Privacy Rights Act ("CPRA"), which became effective in most material respects on January 1, 2023, expands California residents’ rights with respect to certain sensitive personal information. The California Privacy Protection Agency, which was created to enforce the CCPA and CPRA, is also currently in the process of finalizing regulations under the CCPA regarding the use of automated decision making. Other states, including Colorado, have adopted or are considering adopting similar laws. In addition, laws in all 50 U.S. states generally require businesses to provide notice under certain circumstances to consumers whose personal information has been disclosed as a result of a data breach.

On October 30, 2023, the President issued an Executive Order on Safe, Secure and Trustworthy Development and Use of Artificial Intelligence (AI), emphasizing the need for transparency, accountability and fairness in the development and use of AI. The order seeks to address risks associated with AI by providing guiding principles and priorities, including ensuring that consumers are protected from fraud, discrimination and privacy risks related to AI. The Executive Order also requires certain federal agencies, including the CFPB, to address potential discrimination in the housing and consumer financial markets relating to the use by financial institutions of AI technologies. Prior to the issuance of the Executive Order, the CFPB published a report addressing the use by financial institutions of AI chatbots in the provision of financial products and services. The report

also highlighted the limitations and various risks posed by such activity. States have also started to regulate the use of AI technologies.

Risks and exposures related to cybersecurity attacks, including fraud, litigation and enforcement risks, are expected to be elevated for the foreseeable future due to the rapidly evolving nature and sophistication of these threats, as well as due to the expanding use of AI, Internet banking, mobile banking and other technology-based products and services by us and our customers.

See "Legal, Compliance and Reputational Risks—We are subject to complex and evolving laws, regulations, rules, standards and contractual obligations regarding data privacy and cybersecurity, which can increase the cost of doing business, compliance risks, and potential liability." for additional information.

ITEM 1A. RISK FACTORS

An investment in our securities is subject to risks inherent in our business. The material risks and uncertainties that management believes affect us are described below. Additional risks and uncertainties that management is not aware of or that management currently deems immaterial may also impair our business operations. If any of the events described in the risk factors occur, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.

Economic and Overall Market Condition Risks

Our business and financial performance are significantly affected by general business and economic conditions, including those related to increased inflation, recessionary conditions, or domestic and geopolitical factors.

Our business activities and earnings are affected by general business conditions in the United States and particularly in our Bank Markets. Our business is impacted by factors such as economic, political and market conditions, including both general conditions and those specific to the banking industry, changes in the Federal Reserve Board monetary and other governmental fiscal policies, inflation, and interest rate and financial market volatility, all of which may be beyond our control. Future economic conditions cannot be predicted, and any further deterioration in the national economy or in our Bank markets could have an adverse effect, which could be material, on our business, financial condition, operational results. The cost and availability of capital have negatively impacted our business in the past and may adversely impact us in the future. In addition, domestic political factors, including potential future federal government shutdowns and the possibility of the federal government defaulting on its obligations due to debt ceiling limitations, could have a serious impact on general economic conditions or the value of financial instruments owned by us that are issued or guaranteed by the federal government.

Over the past year, the economy has experienced persistent inflation and higher interest rates. Prolonged periods of inflation may negatively affect our expenses by increasing funding costs and expenses related to talent acquisition and retention. Increased interest rates may adversely affect numerous aspects of our business, including by reducing demand for our financial products and services, restricting the ability of our consumer and business customers to repay loans, and decreasing the value of our investment portfolio and collateral securing our loans, and may lead to economic deterioration or recession. Economic deterioration and recessionary conditions that affect household and/or corporate incomes could result in renewed credit deterioration, reduced demand for credit or fee-based products and services and turmoil and volatility in the financial markets, which could, negatively impact our performance. In addition, changes in securities market conditions and monetary fluctuations could adversely affect the availability and terms of funding necessary to meet our liquidity needs.

Our business and financial performance depend upon the continued growth and welfare of the various geographic markets that we serve.

We operate in Bank Markets in Arizona, California, Colorado, Illinois, Iowa, Kansas, Minnesota, Missouri, Montana, New Mexico, Texas and Wisconsin, and our financial condition, results of operations and cash flows depend upon the economic vitality, growth prospects, business activity, population, income levels, deposits and real estate activity in those areas. Adverse economic conditions that affect our specific markets could affect the ability of our customers to repay their loans to us, impact the stability of our deposit funding sources, and adversely affect our financial condition and results of operations.

We are vulnerable to the impact of volatility in debt and equity markets.

As most of our assets and liabilities are financial in nature, our performance is sensitive to the performance of the financial markets. Turmoil and volatility in the domestic and global financial markets can be a major contributory factor to overall weak economic conditions, including the impaired ability of borrowers and other counterparties to meet obligations to us. Financial market volatility may:

•Affect the value or liquidity of the financial instruments we hold.

•Affect our ability to access capital markets to raise funds at cost effective rates or at all.

•Affect the value of the assets that we manage or otherwise administer or service for others, which could decrease fee income, result in decreased demand for our services, and/or decrease the ability of our customers to repay their loans to us.

Any of the above could adversely affect our financial condition and results of operations.

Continued actions by the Federal Reserve Board affecting interest rates and other conditions could negatively impact net interest income and net interest margin.

The Federal Reserve System regulates the supply of money and credit in the United States, and it influences interest rates by changing the discount rate at which it lends money to banks and by adjusting the target for the federal funds rate at which banks borrow from other banks. While out of our control, the Fed's fiscal and monetary policies significantly affect our cost of funds for lending and investing and the return that can be earned on our loans and investments, both of which affect our net interest margin. In addition, decisions by the Federal Reserve to increase or reduce the size of its balance sheet or to engage in tapering its purchase of assets may also affect interest rates. In response to the persistent inflation experienced in the past year, the Federal Reserve Board reacted by implementing significant rate hikes. While these interest rate increases have resulted in reduced inflation, there is continued uncertainty as to whether these actions could lead to an economic downturn. Further, we

cannot predict the nature or timing of future changes in monetary policies or the precise effects that they may have on our activities and financial results.

We have recorded goodwill as a result of acquisitions, and if it becomes impaired, our earnings could be significantly impacted.

Under current accounting standards, goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis or more frequently if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. Although we do not anticipate impairment charges, if we conclude that some portion of our goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded against earnings. A goodwill impairment charge could be caused by a decline in our stock price or occurrence of a triggering event that compounds negative financial results. At December 31, 2023, we had goodwill of $576.0 million, representing approximately 30% of stockholders’ equity.

We have substantial deferred tax assets that could require a valuation allowance and a charge against earnings if we conclude that the tax benefits represented by the assets are unlikely to be realized.

We record deferred tax assets on our consolidated balance sheet, which represent differences in the timing of the benefit of deductions, credits and other items for accounting purposes and the benefit for tax purposes. To the extent we conclude that the value of this asset is not more likely than not to be realized, we would be obligated to record a valuation allowance against the asset, impacting our earnings during the period in which the valuation allowance is recorded. Assessing the need for, or the sufficiency of, a valuation allowance requires management to evaluate all available evidence, both negative and positive. Positive evidence necessary to overcome the negative evidence includes whether future taxable income in sufficient amounts and character within the carryback and carryforward periods is available under the tax law. When negative evidence (e.g., cumulative losses in recent years, history of operating losses or tax credit carryforwards expiring unused) exists, more positive evidence than negative evidence will be necessary. If the positive evidence is not sufficient to exceed the negative evidence, a valuation allowance for deferred tax assets is established. The creation of a substantial valuation allowance could have a significant negative impact on our reported results in the period in which it is recorded. The impact of the impairment of HTLF's deferred tax assets could have a material adverse effect on our business, results of operations and financial condition.

Changes in the federal, state or local tax laws may negatively impact our financial performance.

We are subject to changes in tax law that could increase our effective tax rates. The enactment of such legislation including provisions impacting tax rates, apportionment, consolidation or combination, income, expenses, credits and exemptions may have a material impact on our business, financial conditions and results of operations. These tax law changes may also be retroactive to previous periods and could negatively affect our current and future financial performance. There is no assurance that tax rates will remain at current levels or that presently anticipated benefits will be realized in future years’ financial performance.

Our business and financial performance could be adversely affected, directly or indirectly, by natural disasters, pandemics, terrorist activities, domestic disturbances or international hostilities.

Neither the occurrence nor the potential impact of natural disasters, pandemics, terrorist activities, domestic disturbances or international hostilities can be predicted. However, these occurrences could impact us directly (for example, by interrupting our systems, which could prevent us from obtaining deposits, originating loans and processing and controlling the flow of business; causing significant damage to our facilities; or otherwise preventing us from conducting business in the ordinary course), or indirectly as a result of their impact on our borrowers, depositors, other customers, vendors or other counterparties (for example, by damaging properties pledged as collateral for our loans or impairing the ability of certain borrowers to repay their loans). We could also suffer adverse consequences to the extent that natural disasters, pandemics, terrorist activities, domestic disturbances or international hostilities affect the financial markets or the economy in general or in any particular region. These types of impacts could lead, for example, to an increase in delinquencies, bankruptcies or defaults that could result in higher levels of nonperforming assets, net charge-offs and provisions for credit losses.

Our ability to mitigate the adverse consequences of these occurrences in part depends on the quality of our resiliency planning, and our ability, if any, to anticipate the nature of any such event that occurs. The adverse impact of natural disasters, pandemics, terrorist activities, domestic disturbances or international hostilities also could increase to the extent that there is a lack of preparedness on the part of national or regional emergency responders or on the part of other organizations and businesses that we transact with, particularly those that we depend upon, but have no control over. We may also be subject to compliance with governmental measures taken to address the impact of natural disasters, pandemics, terrorist activities or other occurrences of this nature.

Climate regulation and climate change risks, including transition, physical or other risks could adversely affect our operations, businesses, customers, reputation and financial condition.

There is an increasing concern over the risks of climate change and related environmental sustainability matters. For example, the Federal Reserve Board in its Financial Stability Report of November 2020, specifically addressed the implications of climate change for markets, financial exposures, financial institutions, and financial stability. As a result of these concerns, Congress, state legislatures and federal and state regulatory agencies have continued to propose legislative and regulatory initiatives seeking to mitigate the effects of climate change, including disclosure requirements regarding greenhouse gas emissions. Further, the SEC has proposed climate-related disclosure rules, which if finalized, would require new climate-related disclosures in SEC filings and audited financial statements, including certain climate-related metrics and direct and indirect greenhouse gas emissions data, information about climate-related targets and goals, transition plans, if any, and would have attestation requirements. The State of California has enacted, and other states may enact, laws and regulations requiring expanded measurement and disclosure of greenhouse gas emissions, including scopes 1, 2, and 3 emissions, and requiring third-party assurance of their reports. Disclosure requirements imposed by different regulators may not always be uniform, which may result in increased complexity, increased compliance costs, and other compliance-related risks. On October 24, 2023, the federal banking agencies issued interagency guidance on principles for climate-related financial risk management by large financial institutions. The guidance reiterates the agencies’ view that financial institutions are likely to be affected by both the physical risks and transition risks associated with climate change.

The physical risks of climate change include not only discrete events such as natural disaster events described above, the force and frequency of which are increasing as the climate changes, but also longer-term shifts in climate patterns, such as extreme heat, sea level rise, and more frequent and prolonged drought. We do not yet know all the ways that climate change may affect us and our customers, however weather disasters, shifts in local climates and other disruptions related to climate change may adversely affect our customers, particularly agricultural customers, or the value of real properties securing our loans, any of which could diminish the value of our loan portfolio.

Attempts to mitigate climate change, such as transitioning to a low-carbon economy, may include extensive policy, legal, technology and market initiatives. Transition risks, including changes in consumer preferences, additional regulatory, governance, and disclosure requirements or taxes and additional counterparty or customer requirements, could increase our expenses, require changes to our strategies and impact our financial condition. In addition, our reputation and client relationships may be damaged as a result of our practices related to climate change, including our involvement, or our clients’ involvement, in certain industries or projects associated with causing or exacerbating climate change, as well as any decisions we make to continue to conduct or change our activities in response to considerations relating to climate change.

Our framework for managing risks may not be effective in identifying or mitigating risk and losses.

Our risk management framework seeks to identify, monitor, manage and mitigate risk of material loss. We have established processes and procedures and dedicated resources intended to identify, measure, monitor, report, and analyze the types of risk to which we are subject, including liquidity risk, credit risk, market risk (including interest rate and price risk), compliance risk, strategic risk, reputation risk, and operational risk related to our employees, systems, processes and vendors, among others. However, as with any risk management framework, there are inherent limitations to our risk management strategies as there may exist, or develop in the future, risks that it has not appropriately anticipated or identified or that are out of our control. We must also develop and maintain a culture of risk management among our employees, as well as manage risks associated with third parties, and could fail to do so effectively. If our risk management framework proves ineffective, we could incur litigation and negative regulatory consequences, and suffer unexpected material losses that could affect our financial condition or results of operations.

Credit Risks

If we do not properly manage our credit risk, we could suffer material credit losses.

There are substantial risks inherent in making any loan, including, but not limited to:

•risks resulting from changes in economic and industry conditions, including those precipitated by climate change or climate transition in the economy;

•risks inherent in dealing with individual borrowers, including fraud-related risks;

•uncertainties as to the future value of collateral; and

•the risk of non-payment of loans.

Although we attempt to properly establish limits, measure, monitor and manage our credit risk through prudent loan policies, loan underwriting procedures and by monitoring concentrations of our loans, there can be no assurance that these policies, underwriting and monitoring procedures will effectively reduce these risks. Moreover, if we expand into new markets, credit administration and loan underwriting policies and procedures may need to be adapted further to local conditions. The inability to properly manage our credit risk or appropriately adapt our credit administration and loan underwriting policies and

procedures to local market conditions or to changing economic circumstances could have an adverse impact on our allowance and provision for credit losses and our financial condition, results of operations and liquidity.

In addition, certain of our investment securities may carry material credit risk, and as a result, we may have to record provision expense to establish an allowance for credit losses on our carried at fair value debt securities.

We are subject to lending concentration risks.

In the ordinary course of business, we have credit exposures to specific industries, regions, financial markets, or individual borrowers. As an example, loans secured by commercial and residential real estate typically represent a significant percentage of our overall credit portfolio. Although there are established limitations on the extent of total exposure to an individual consumer or business borrower, events adversely affecting specific customers or counterparties, industries, regions, or financial markets, including a decline in their creditworthiness or a worsening overall risk profile, could materially and adversely affect us. Declining economic conditions also may disproportionately impact different types of customers. Certain of our credit exposures are concentrated in industries and may share similar characteristics which can make them more susceptible to different adverse events and conditions. Thus, the concentration and mix of our loan portfolio may affect the severity of the impact of a recession or other adverse events on us and our financial performance in ways that we cannot anticipate.

We depend on the accuracy and completeness of information about our customers and counterparties.

In deciding whether to extend credit or enter into other transactions, we rely on information furnished by or on behalf of customers and counterparties, including financial statements, credit reports and other financial information. We may also rely on representations of those customers, counterparties or other third parties, such as independent auditors, regarding the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports or other financial information could cause us to make uncollectible loans or enter into other unfavorable transactions, which could have a material adverse effect on our financial condition and results of operations.

Our loan portfolio has a large concentration of commercial real estate loans, a segment that can be subject to volatile cash flows and collateral values which may be impacted by changes in industry trends or regional and national market conditions.

Commercial real estate lending, which is comprised of owner-occupied, non-owner occupied, and real estate construction loans, represents a large portion of our commercial loan portfolio. The market value of real estate can fluctuate significantly in a short period of time as a result of market conditions in any of our geographic Bank Markets in which the real estate is located. Adverse developments in nationwide or regional market conditions affecting real estate values could negatively impact our commercial real estate loans, and other developments could increase the credit risk associated with our loan portfolio. For example, the decrease in demand for physical office space has reduced, and may continue to reduce, the value of certain commercial space, which increases the risk of default and the severity of defaults associated with loans secured by such properties. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. With recent increases in interest rates, borrowers with variable rate loans may not have sufficient cash flows to absorb the impact of higher interest rates on their payments. In addition, increases in interest rates could also negatively impact the cash flows and repayment ability of our borrowers.

Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project and therefore have a greater risk of default in a weaker economy. Construction projects require prudent underwriting including determination of a borrower's ability to complete the project, while staying within budget and on time in accordance with construction plans. While we follow prudent underwriting practices, including determining project feasibility on construction projects we finance, economic events, supply chain issues, labor market disruptions, and other factors outside of the control of HTLF or our borrowers could negatively impact the future cash flow and market values of the affected properties.

We may encounter issues with environmental law compliance if we take possession, through foreclosure or otherwise, of the real property that secures a commercial real estate loan.

A significant portion of our loan portfolio is secured by real property. During the ordinary course of business, we may foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If previously unknown or undisclosed hazardous or toxic substances are discovered, we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses which may materially reduce the affected property's value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase our exposure to environmental liability. Although we have policies and procedures to perform an environmental review at the time of underwriting a loan secured by real property and also before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other

financial liabilities associated with an environmental hazard could have a material adverse effect on our financial condition and results of operations.

The ability of a borrower to repay agricultural loans may be especially affected by many factors outside of the borrower’s control.

Payments on agricultural and agricultural real estate loans depend on the profitable operation or management of the farm property securing the loan. If the cash flow from a farming operation is diminished, the borrower's ability to repay the loan may be impaired. Loans that are unsecured or secured by rapidly depreciating assets such as farm equipment or assets such as livestock or crops may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage to or depreciation in the value of crops or livestock.

The success of a farm may be affected by many factors outside the control of the borrower, including adverse weather conditions that prevent the planting of a crop or limit crop yields (such as hail, extreme weather or temperatures, drought, and floods), loss of livestock due to disease or other factors, declines in market prices for agricultural products (both domestically and internationally) and the impact of government regulations (including changes to global trade agreements, tariffs, price supports, subsidies and environmental regulations). In addition, many farms depend on a limited number of key individuals whose injury or death may significantly affect the successful operation of the farm.

Our allowance for credit losses may prove to be insufficient to absorb losses in our loan portfolio.

We establish our allowance for credit losses in consultation with management of HTLF Bank and maintain it at a level considered appropriate by management to absorb current expected credit losses and risks inherent in the portfolio. While the level of allowance for credit losses reflects management's continuing evaluation of quantitative and qualitative factors including industry concentrations, loan portfolio quality and economic conditions, the amount of future loan losses is susceptible to changes in economic, operating and other conditions, including changes in interest rates, levels of inflation, and other factors which may be beyond our control, and such losses may exceed current estimates. At December 31, 2023, our allowance for credit losses as a percentage of total loans was 1.02% and as a percentage of total nonperforming loans was approximately 125%. Although we believe that the allowance for credit losses is appropriate to absorb current expected credit losses on any existing loans that may become uncollectible, we cannot predict loan losses with certainty, and we cannot provide assurance that our allowance for credit losses will prove sufficient to cover actual loan losses in the future. Further significant provisions, or charge-offs against our allowance that result in provisions, may adversely affect our business, financial condition and results of operations.

Liquidity and Interest Rate Risks

Our financial results are significantly affected by interest rate levels and fluctuation.

Our financial results depend to a large extent on net interest income, which is the difference between interest income earned on loans and investment securities and interest expense paid on deposits, subordinated notes, borrowings, and other liabilities. Due to differences in maturities and repricing characteristics of our interest-earning assets and interest-bearing liabilities, changes in interest rates may not produce equivalent changes in interest income earned on interest-earning assets and interest paid on interest-bearing liabilities. For example, asset values, especially values of commercial real estate collateral, securities, or other fixed rate earning assets, can decline significantly with relatively minor changes in interest rates. As a result, an increase or decrease in rates, loan portfolio duration, the mix of adjustable and fixed rate loans in our portfolio, and the cost, stability, and mix of deposits on our balance sheet all could have a negative effect on our financial condition, results of operation, and liquidity. Ongoing fluctuations in interest rates could adversely affect our interest rate spread, and, in turn, our profitability. Future monetary actions taken by the Federal Reserve to address various economic factors can further constrain our interest rate spread and impact the mix of noninterest and interest-bearing accounts. If the interest we pay on liabilities increases at a faster pace than the interest that we receive on our interest-earning assets, the result could be a reduction in net income.

In addition, the failure to match the durations of our assets and liabilities could result in us being unable to mitigate the impact of changes in interest rates. We measure interest rate risk under various rate scenarios using specific criteria and assumptions. A summary of this process, along with the results of our net interest income simulations, is presented under the caption "Quantitative and Qualitative Disclosures About Market Risk" included under Item 7A of Part II of this Annual Report on Form 10-K. Although we believe our current level of interest rate sensitivity is reasonable and effectively managed, significant fluctuations in interest rates may have an adverse effect on our business, financial condition and results of operations, and specifically, our net interest income. Also, our interest rate risk modeling techniques and assumptions may not fully predict or capture the impact of actual interest rate changes on our financial condition and results of operations. We cannot control nor predict future changes in the Federal Reserve's monetary policy or actions taken to address inflation, recession, unemployment, money supply and other changes in financial markets.

We may not be able to meet the cash flow requirements of our depositors or borrowers, or be able to meet our obligations or the cash needs for expansion or other strategic corporate activities.

Liquidity represents our ability to provide funds to satisfy demands from depositors, and facilitates our ability to extend loans to borrowers and meet our contractual debt obligations by either converting assets into cash or accessing new or existing sources of incremental funds. Liquidity risk is the potential that we will be unable to meet our obligations as they become due because of an inability to liquidate assets or obtain adequate funding. We manage liquidity risk with the primary objective of meeting our cash flow requirements including those from our depositors and creditors, and having sufficient cash to satisfy our operating needs, strategic initiatives and loan growth objectives while maintaining reasonable funding costs. We primarily rely on deposits, repayments of loans and cash flows from our investment securities as our primary sources of funds. Our principal deposit sources include consumer and commercial customers in our markets. We have used these funds, together with public funds customers, brokered deposits and Federal Home Loan Bank ("FHLB") advances as well as federal funds purchased and other sources of short-term borrowings to make loans, acquire investment securities and other assets and to fund continuing operations.

Deposit levels may be affected by a number of factors, including competition, general interest rate levels, returns available to customers on alternative investments, concerns about the stability of banks, general economic and market conditions and other factors. Our access to deposits can be impacted by the liquidity needs and financial condition of our customers, particularly large customers, as a substantial portion of our deposit liabilities are demand deposits, while a significant portion of our assets are loans that cannot be sold in the same timeframe or are investment securities the value of which may be impaired, or which we may not be readily able to sell if there is disruption in capital markets. Although we maintain asset/liability management policies and a related contingency funding plan that, among other things, include policies and procedures for managing and monitoring liquidity risk, there can be no assurance that these will prove adequate to our needs. If we are unable to access additional funding sources when needed, we might be unable to meet our depositors’, borrowers’ or creditors’ needs, which would adversely affect our financial condition, results of operations and liquidity.

Significant reductions in our core deposits or increases in our cost of funding could adversely affect our liquidity or profitability.

Our profitability depends in part on successfully gathering and retaining a stable base of relatively low-cost deposits, as deposits have traditionally served as our largest, least costly source of funding. The competition for these deposits has increased dramatically in the last year, and our deposit levels might fall, or our cost of deposits may significantly increase, if the total supply of deposits decreases due to economic events, or if competition increases to attract deposits, either of which could have an adverse effect on our financial position, results of operations and liquidity.

We use brokered deposits and other wholesale funding, which may be unstable and/or expensive, to fund earning asset growth.

We use wholesale and institutional deposits, including brokered deposits, as a source of funding to augment deposits generated from our branch network. At December 31, 2023, we had $1.35 billion in wholesale and institutional deposits, of which $1.16 billion consisted of brokered deposits. Our ability to use these deposits is limited by our own internal policies as well as regulatory limitations, and there can be no assurance that such sources will be available, or will remain available, or that the cost of such funding sources will be reasonable. For example, if we are no longer considered well-capitalized, our ability to access new brokered deposits or retain existing brokered deposits could be adversely affected by regulatory requirements, the unwillingness of counterparties to do business with us, or both, which could result in most, if not all, brokered deposit sources being unavailable.

In addition, we also utilize other wholesale funding sources to provide us with liquidity and fund our asset growth. As of December 31, 2023, we had approximately $521 million in borrowings from the FHLB, which represents a significant source of our wholesale borrowings. In the event of market disruptions, changes in our creditworthiness, or other unavailability of FHLB borrowings in the future, sources of wholesale funding may not be available to us on reasonable terms, or at all. The inability to utilize wholesale deposits, including brokered deposits, or other wholesale funding could have an adverse effect on our financial position, results of operations and liquidity.

Our investment securities portfolio may be impacted by interest rate volatility and market conditions.

As of December 31, 2023, $5.58 billion, or 29%, of the assets on our balance sheet consisted of investment securities. Changes in interest rates can negatively affect the value of most of our investment securities. Interest rates are highly sensitive to many factors including monetary policies, domestic and international economic and geopolitical issues, and other factors beyond our control as interest volatility can result in unrealized gains or losses in our portfolio. Additionally, actual investment income and cash flows from investment securities that carry prepayment risk, such as mortgage-backed securities and callable securities, may materially differ from our initial expectations due to changes in interest rates and market conditions. Our investment securities portfolio is also subject to potential credit deterioration as financial distress is another risk that may impact the ability

of a security to pay principal and interest in a timely manner. Factors such as deteriorating financial conditions of the issuer, changes in the issuer's creditworthiness, or adverse market conditions can contribute to financial distress. We may need to establish an allowance for credit losses on our debt securities carried at fair value. This assessment involves testing at the security level, considering factors such as changes in security ratings, the financial condition of the issuer, payment structure, cash flow analyses, and security and industry-specific economic conditions. Although the reduction in value from temporary increases in market rates does not affect our income until the security is sold, it does result in an unrealized loss recorded in other comprehensive income that can reduce our common stockholders’ equity. Other factors such as changes in market conditions, regulatory changes, counterparty risk could also impact the performance and value of our investment portfolio and potentially result in financial losses.

The required accounting treatment of loans we acquire through acquisitions could result in lower net interest margins and interest income in future periods.

Under United States GAAP, we are required to record loans acquired through acquisitions, at fair value. Estimating the fair value of such loans requires management to make estimates based on available information and facts and circumstances on the acquisition date. Any net discount, which is the excess of the amount of reasonably estimable and probable discounted future cash collections over the purchase price, is accreted into interest income over the weighted average remaining contractual life of the loans. As acquired loans pay down, mature, or if they are not replaced with higher-yielding loans, we may have a lower net interest margin and interest income in future periods.

Our growth may create the need to raise additional capital in the future, but that capital may not be available when it is needed.

We are required by federal and state regulatory authorities to maintain adequate levels of capital to support our operations. We anticipate that our existing capital resources will satisfy our capital requirements for the foreseeable future. However, from time to time, we raise additional capital to support continued growth, both internally and through acquisitions. Our ability to raise additional capital, if needed, will depend on conditions in the capital markets at that time, which are outside of our control, and on our financial performance. Accordingly, we cannot provide assurance that we will be able to raise additional capital if needed on terms acceptable to us. If we cannot raise additional capital when needed, our ability to further expand our operations through internal growth and acquisitions could be materially impaired.

We rely on dividends from HTLF Bank for most of our liquidity and are subject to restrictions on payment of dividends.

The primary source of funds for HTLF is dividends from HTLF Bank. In general, HTLF Bank may only pay dividends either out of their historical net income after any required transfers to surplus or reserves have been made or out of their retained earnings. The payment of dividends by any financial institution is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and a financial institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. These dividends are the principal source of funds to pay dividends on HTLF's common and preferred stock and to pay interest and principal on our debt. Dividends payable on common shares are also subject to the requirement that we must pay quarterly dividends on our outstanding preferred stock at the applicable dividend rate in order to declare dividends on our common stock.

Operational Risks

We have a continuing need for technology investments, and we may not have the resources to effectively implement new technology.

The financial services industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In addition to being able to better serve customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as to create additional efficiencies in our operations as we continue to grow and expand our market areas. Many of our larger competitors have substantially greater resources to invest in technological improvements. As a result, they may be able to offer additional or superior products and services to those that we will be able to offer, which would put us at a competitive disadvantage. In addition, our need to address the changing needs, preferences, and best interests of our employees, customers, and business partners has accelerated the need to implement technological changes.

Our operations are affected by risks associated with our use of vendors and other third-party service providers.

We rely on vendor and third-party relationships for a variety of products and services necessary to maintain our day-to-day activities, particularly in the areas of correspondent relationships, operations, treasury management, information technology and security. This reliance exposes us to risks of those third parties failing to perform financially or contractually or to our expectations. These risks could include material adverse impacts on our business, such as credit loss or fraud loss, disruption or

interruption of business activities, cyber-attacks and information security breaches, poor performance of services affecting our customer relationships and/or reputation, and possibilities that we could be responsible to our customers for legal or regulatory violations committed by those third parties while performing services on our behalf. In addition, changes to work preferences and environments have increased the risk of third-party disruptions, including negative effects on network providers and other suppliers, which have been, and may further be, affected by, market volatility and other factors that increase their risks of business disruption or that may otherwise affect their ability to perform under the terms of any agreements with us or provide essential services. While we have implemented an active program of oversight to address this risk, there can be no assurance that our vendor and third-party relationships will not have a material adverse impact on our business.

Security breaches, cyber-attacks or other similar incidents with respect to our or our vendors’ systems or network security, as well as the resulting theft or compromise of business and customer information, including personal information, could adversely affect our business or reputation, and create significant legal, regulatory or financial exposure.

We rely heavily on communications and information systems and networks to conduct our business, and as part of our business, we collect, maintain and otherwise process significant amounts of data (including confidential, personal, proprietary and other information) about our business, our customers and the products and services they use. Our operations depend upon our ability to protect our communications and information systems and networks against damage from physical theft, fire, power loss, telecommunications failure or a similar catastrophic event, as well as from security breaches, cyber-attacks or other similar incidents. Our business relies on the secure processing, transmission, storage and retrieval of confidential, personal, proprietary and other information in our communication and information systems and networks, and in communication and information systems and networks of third parties with which we do business.

We, our customers, our vendors and other third parties, including other financial service institutions and companies engaging in data processing, have been subject to, and are likely to continue to be the target of cyber-attacks, attempts to breach our network security, and other similar incidents. These cyber-attacks, attempts to breach our network security, and other similar incidents include, denial of service attacks, worms, computer viruses, malicious or destructive code, social engineering, phishing attacks, ransomware, malware, theft, malfeasance or improper access by employees or vendors, human error, fraud, attacks on personal emails of employees or other disruptive problems that could result in material disruptions, damage to systems or networks, or the unauthorized release, accessing, gathering, monitoring, loss, destruction modification, acquisition, transfer, use or other processing of confidential, personal, proprietary, or other information of ours, our employees, our customers, our vendors, or other third parties with which we do business. Attacks of this nature are increasing in frequency, levels of persistence, sophistication, and intensity, are evolving in nature, and are conducted by sophisticated and organized groups and individuals with a wide range of motives and expertise, including organized criminal groups, "hacktivists," terrorists, nation states, nation state-supported actors, and others. As cybersecurity threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate or remediate any information security vulnerabilities, threats, security breaches, cyber-attacks or other similar incidents. Despite efforts to protect our systems and networks and implement controls, processes, policies, and other measures, we may not be able to anticipate all security breaches, cyber-attacks or other similar incidents, or be able to detect or react to such incidents in a timely manner, implement guaranteed preventive measures against such incidents, or adequately remediate any such incident.

Cybersecurity and payment fraud risks for banking organizations have significantly increased in recent years in part because of the proliferation and rapid evolution of new technologies, increased remote work, and the use of the internet and telecommunication technologies to conduct financial transactions. For example, cybersecurity risks may increase in the future as we continue to increase our mobile-payment and other internet-based products offerings and increase our internal usage of web-based products and applications. Given the continued and rapid evolution of cybersecurity threats, we may not be able to anticipate or prevent, and could be held liable for, any security breach, cyber-attack or other similar incident. Additionally, concerns or perceptions regarding the effectiveness or adequacy of our measures to safeguard our communications and information systems and networks, and information stored therein, could cause us to lose existing or potential customers and thereby reduce our revenues.

We also face indirect technology, cybersecurity and operational risks relating to the vendors, customers, clients and other third parties with whom we do business or upon whom we rely to facilitate or enable our business activities, including for example financial counterparties, regulators, and providers of critical infrastructure such as internet access or electrical power. Due to the increasing consolidation, interdependence, and complexity of financial entities and technology systems, a security breach, cyber-attack or other similar incident that significantly degrades, destroys, or comprises the systems, networks or data of one or more financial entities could have a material impact on counterparties or other market participants, including us. This consolidation, interconnectivity and complexity may increase the risk of operational failure on both an individual and industry-wide basis. Although we perform cybersecurity diligence through our Third Party Risk Management group on our key vendors, our ability to monitor their cybersecurity is limited, and we cannot ensure the cybersecurity measures they take will be sufficient to protect any information we share with them. Due to applicable laws and regulations or contractual obligations, we

may be held responsible for security breaches, cyber-attacks or other similar incidents affecting our vendors because they relate to the information we share with them.

The occurrence of any security breach, cyber-attack or other similar incident with respect to our or our vendors’ communications or information systems or networks, or our failure to make adequate or timely disclosures to the public, regulators, or law enforcement agencies following any such event, could result in violations of applicable data privacy, cybersecurity and other laws and regulations, notification obligations, and could result in damage to our reputation and loss of customer business, or subject us to additional regulatory scrutiny or civil litigation, fines, damages, or injunctions, any of which could have a material adverse effect on our business, financial condition and results of operations. We cannot ensure that any limitations of liability provisions in our agreements with customers, vendors and other third parties with which we do business would be enforceable or adequate, or would otherwise protect us from any liabilities or damages with respect to any particular claim in connection with a security breach, cyber-attack or other similar incident. We also cannot be certain that our insurance coverage will be adequate for cybersecurity liabilities actually incurred, that insurance will continue to be available to us on economically reasonable terms, or at all, or that our insurer will not deny coverage as to any future claim.

The potential for business interruption or failure exists throughout our organization.

Integral to our performance is the continued efficacy of our technical systems, operational infrastructure, and relationships with third parties, as well as the ability of our employees to perform their jobs day-to-day to support our on-going operations. Failure by any or all these resources subjects us to risks that may vary in size, scale and scope. These risks include, but are not limited to, operational or technical failures, interruptions in third-party support, and the loss of key individuals, including those with specialized skills, or the failure of key individuals to perform properly. These risks are heightened during necessary data system changes or conversions and system integrations of newly acquired entities. Although management has established policies and procedures to address such interruptions or failures, the occurrence of any such event could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations.

We are subject to risks from employee errors, customer or employee fraud and data processing system failures and errors.

Employee errors and employee or customer misconduct could subject us to financial losses or regulatory enforcement actions, and could harm our reputation. Misconduct by our employees could include hiding unauthorized activities from us, improper or unauthorized activities on behalf of our customers, or improper use of confidential information. It is not always possible to prevent employee errors and misconduct, and the precautions we take to prevent and detect this activity may not be effective in all cases. Employee errors could also subject us to financial claims for negligence. Although we maintain a system of internal controls and insurance coverage to mitigate these operational risks, including data processing system failures and errors and customer or employee fraud, these internal controls may fail to prevent or detect an occurrence, or the resulting loss may not be covered or may exceed applicable insurance limits, any of which it could have a material adverse effect on our business, financial condition and results of operations.

Our Bank Markets and growth strategy rely heavily on our management team, and the unexpected loss of key managers may adversely affect our operations.

Much of our success to date has been influenced strongly by our ability to attract and to retain senior management experienced in banking and financial services and familiar with the communities in our different market areas. Because our service areas are spread over such a wide geographical area, our executive management depends on the effective leadership and capabilities of the senior management in our Bank Markets for our continued success. Our ability to retain executive officers, senior management teams, and other key personnel, will continue to be important to our success, and could be difficult during times of low unemployment. It is also critical to the success of our banking strategy to be able to attract and retain qualified management and key personnel with the appropriate level of experience and knowledge about our market areas. The unexpected loss of any key management personnel, or the inability to recruit and retain qualified personnel in the future, could have an adverse effect on our business, financial condition and results of operations.

New lines of business, products, and services are essential to our ability to compete, but may subject us to additional risks.

We may implement new lines of business and offer new products and services within existing lines of business to offer our customers a competitive array of products and services. There can be substantial risks and uncertainties associated with these efforts, particularly in instances where such products and services are still developing. In developing and marketing new lines of business and/or new products or services, we may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved, and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market preferences, may also impact the successful implementation of a new line of business or a new product or service, and any new line of business and/or new product or service could have a significant impact on the effectiveness of our system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business or new products or services could have a material adverse effect on our business, financial condition and results of operations.

Our analytical and forecasting models may be improper or ineffective.

The processes we use to estimate our current expected credit losses and to measure the fair value of financial instruments, as well as the processes used to estimate the effects of changing interest rates and other market measures on our financial condition and results of operations, depend upon the use of analytical and forecasting models. These models could reflect assumptions that may not be accurate, particularly in times of market stress or other unforeseen circumstances. Even if these assumptions are adequate, the models may prove to be inadequate or inaccurate because of other flaws and limitations in their design or their implementation. If the models we use to guide management's decisions and oversight relating to interest rate risk and asset-liability management are inadequate, we may incur increased or unexpected losses upon changes in market interest rates or other market measures. If the models we use for determining our probable loan losses are inadequate, the allowance for credit losses may not be appropriate to support future charge-offs. If the models we use to measure the fair value of financial instruments are inadequate, the fair value of such financial instruments may fluctuate unexpectedly, or may not accurately reflect what we could realize upon sale or settlement of such financial instruments. Any such failure in our analytical or forecasting models could have a material adverse effect on our business, financial condition and results of operations.

Our internal controls may be ineffective.

Management regularly reviews and updates our internal controls, disclosure controls and procedures and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the controls are met. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls, policies and procedures could have a material adverse effect on our business, financial condition and results of operation.

Strategic and External Risks

The soundness of other financial institutions could adversely affect our liquidity and operations.

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships. We have exposure to many different counterparties, and we routinely execute transactions with counterparties in the financial industry, including brokers and dealers, commercial banks, government sponsored entities, investment banks, and other institutional clients. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, have led to market-wide liquidity problems and could lead to losses or defaults by HTLF or HTLF Bank or by other institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be exacerbated when the collateral held by us cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due us. There is no assurance that any such losses would not materially and adversely affect our results of operations.

We may experience difficulties in achieving and managing our growth and our growth strategy involves risks that may negatively impact our net income.

Growth is an integral component of achieving business and financial scale and results necessary to make appropriate investments in people, processes and systems which allow HTLF to remain competitive in attracting and retaining employees and customers. As part of our general growth strategy, we have acquired, and may acquire, additional banks, fee income businesses and other financial services businesses that we believe provide a strategic and geographic fit with our business. We expect to continue to make such acquisitions in the future. We cannot predict the number, size or timing of acquisitions, and failure to successfully identify and complete meaningful and accretive acquisitions likely may result in HTLF achieving slower growth. To the extent that we grow through acquisitions, we cannot provide assurance that we will be able to manage this growth adequately and profitably. Acquiring other banks and businesses will involve risks commonly associated with acquisitions, including:

•potential exposure to unknown or contingent liabilities of the banks and businesses we acquire;

•exposure to potential asset quality issues of the acquired bank or related business;

•difficulty and expense of integrating the operations and personnel of banks and businesses we acquire;

•potential disruption to our business;

•potential restrictions on our business resulting from the regulatory approval process;

•inability to realize the expected revenue increases, costs savings, market presence and/or other anticipated benefits;

•potential diversion of our management's time and attention; and

•the possible loss of key employees and customers of the banks and businesses we acquire.

In addition to acquisitions, we may expand into additional communities or attempt to strengthen our position in our current Bank Markets by undertaking additional branch openings. Based on our experience, we believe that it generally takes three years or more for new banking facilities to first achieve operational profitability, due to the impact of organizational and overhead expenses and the start-up phase of generating loans and deposits. To the extent that we undertake additional branching and business formations, we are likely to continue to experience the effects of higher operating expenses relative to operating income from the new operations, which could have a material adverse effect on our business, financial condition and results of operation.

Attractive acquisition opportunities may not be available to us in the future.

While our focus is on continued organic growth, we anticipate continuing to evaluate merger and acquisition opportunities presented to us in our Bank Markets. Economic conditions as well as the need for technological investment by regional banks could result in increased competition for merger or acquisition partners. We expect that other banking and financial companies, many of which have significantly greater resources, will compete with us to acquire financial services businesses. This competition, as the number of attractive merger targets decreases, could increase prices for potential acquisitions, which could reduce our potential returns, and reduce the attractiveness of these opportunities to us. Acquisitions also are subject to various regulatory approvals, and if we fail to receive the appropriate regulatory approvals, we will not be able to consummate an acquisition that we believe is in our best interests. Among other things, our regulators consider our capital, liquidity, profitability, risk management, regulatory compliance, including with respect to BSA/AML, consumer protection laws, CRA obligations, and levels of goodwill and intangibles when considering acquisition and expansion proposals. The federal banking agencies are currently reevaluating their existing requirements and policies for reviewing mergers and acquisitions involving banking organizations, which could make it more difficult for us to pursue mergers and acquisitions in the future. Any acquisition could be dilutive to our earnings and shareholders’ equity per share of our common stock.

We face intense competition in all phases of our business, and competitive factors could adversely affect our business.

The banking and financial services business in HTLF Bank's Markets is highly competitive and is currently undergoing significant change. Our competitors include other commercial banks, credit unions, thrifts, fintech firms, stockbrokers, securities and brokerage companies, mutual Fund companies, mortgage companies, insurance companies and other non-bank financial service companies. Increasingly these competitors provide integrated financial services over a broad geographic area. Technology companies are increasingly focusing on the financial sector, either in partnership with competing banking organizations or on their own. These companies generally are not subject to the same regulatory requirements as traditional financial institutions and may therefore have cost advantages over us and offer products and services at more favorable rates and with greater convenience to the client. This competition could result in the loss of clients and revenue in areas where Fintech's, many of which operate nationally without physical locations, are operating. As the pace of technology and change advance, continuous innovation is expected to exert long-term pressure on the financial services industry. Some of our competitors may also have a competitive advantage over us due to their access to governmental programs that we do not have access to that impact their position in the marketplace favorably. 

The adoption of new technologies and products by competitors, including internet banking services, mobile applications, advanced ATM functionality and cryptocurrencies could require us to make substantial investments to modify or adapt our existing products and services or even radically alter the way we conduct business. These and other capital investments in our business may not produce the expected growth in earnings anticipated at the time of the expenditure.

Increased competition in our Bank Markets may result in changes in our business model, sales of certain assets or business units, decreases in the amounts of our loans and deposits, reduced spreads between loan rates and deposit rates or loan terms that are more favorable to the borrower. Any of these could impact our ability to grow and scale our business, which could have an adverse effect on our ability to profitably compete.

Legal, Compliance and Reputational Risks

We are subject to extensive and evolving government regulation and supervision, which can increase the cost of doing business, limit our ability to grow, and lead to enforcement actions.

Federal and state banking laws impose a comprehensive system of supervision, regulation and enforcement on the operations of FDIC-insured institutions, their holding companies and affiliates that is intended primarily for the protection of the FDIC-insured deposits and depositors of banks, rather than shareholders. These laws, and the regulations of the bank regulatory agencies issued under them, affect, among other things, the scope of our business, the kinds and amounts of investments that we may make, our reserve requirements and required capital levels, the nature and amount of collateral for loans, the establishment of branches, our ability to merge, consolidate and acquire, our dealings with our insiders and affiliates, and our payment of dividends.

Both the scope of the laws and regulations and the intensity of the supervision to which our business is subject have increased in recent years, as has the complexity of our business and the risks to which we are subjected due to technological and market changes. For example, as cybersecurity and data privacy risks for banking organizations and the broader financial system have significantly increased in recent years, cybersecurity and data privacy issues have become the subject of increasing legislative and regulatory focus. Regulatory enforcement and fines have increased across the banking and financial services sectors.

We expect a continued emphasis on regulatory reform, including a heightened focus on consumer protection, fair lending, the regulation of loan portfolios and credit concentrations to borrowers impacted by climate change, heightened scrutiny on Bank Secrecy Act ("BSA")/Anti-Money Laundering ("AML") and Countering the Financing of Terrorism ("CFT") requirements, topics related to social equity, executive compensation, and increased capital and liquidity, as well as limits on share buybacks and dividends. For example, recent changes in our overdraft practices resulting from regulatory and competitive pressures will result in lower future noninterest income. Other products or services of ours may be subjected to increased regulation in the future, and such regulation may impact our ability to profitably provide services to our customers, which may result in difficulties competing with larger institutions which have more resources. It is uncertain how changes in existing regulations and their enforcement may require modification to HTLF's existing business strategy, regulatory compliance, and risk management infrastructure and practices, and how these may impact our financial results in the future.

In the routine course of regulatory oversight, proposals to change the laws and regulations governing the operations of banks and other financial institutions are frequently raised in the U.S. Congress, state legislatures and before bank regulatory authorities. Similarly, proposals to change the accounting and financial reporting requirements applicable to banks and other depository financial institutions are frequently raised by the SEC, the federal banking agencies and other authorities. We expect that the recent failures in the banking industry are likely to increase future regulations on banks, and the specific changes in laws and regulations in the future and the effect such changes might have on our results of operations and financial condition are impossible to determine.

Stringent requirements related to capital may limit our ability to return earnings to stockholders or operate or invest in our business.

As a banking organization, we are subject to regulations that require us to maintain certain capital ratios, such as the ratio of our Tier 1 capital to our risk-weighted assets. Failure to satisfy certain capital requirements could result in restrictions on our ability to make capital distributions. If our regulatory capital ratios decline, because of decreases in the value of our loan portfolio, investment portfolio, or otherwise, we may be required to improve such ratios by either raising additional capital or by disposing of assets. If we choose to dispose of assets, we cannot be certain that we will be able to do so at prices that we believe to be appropriate, and our future operating results could be negatively affected. If we choose to raise additional capital, we may accomplish this by selling additional shares of common stock, or securities convertible into or exchangeable for common stock, which could significantly dilute the ownership percentage of holders of our common stock and cause the market price of our common stock to decline. Additionally, events or circumstances in the capital markets generally may increase our capital costs and impair our ability to raise capital at any given time.

Additional requirements may be imposed on us in the future. The Basel Committee continues to examine ways to strengthen the regulation, supervision and practices of banks and has produced, and continues to produce consultation and discussion papers which point to a significant revision of the Basel Framework, including improvements to the calculation of risk-weighted assets and the comparability of capital ratios. The ultimate impact on our capital and liquidity will depend on the implementation of further changes in the United States banking sector.

We are becoming subject to additional regulatory requirements as our total assets increase, and these additional requirements could have an adverse effect on our financial condition or results of operations.

Various federal banking laws and regulations impose heightened requirements on larger banks and bank holding companies. These heightened requirements have added, and will continue to add, restrictions on, and complexity to, our business operations, as we expand. For example, as a result of consolidation of our Banks in 2023, we became subject to CFPB supervision.

Although the Economic Growth Act exempted bank holding companies under $100 billion in assets from certain Dodd-Frank Act requirements that were otherwise applicable to bank holding companies with greater than $10 billion and $50 billion in total consolidated assets, federal banking agencies have indicated through interagency guidance that the capital planning and risk management practices of institutions with total assets less than $100 billion would continue to be reviewed through the regular supervisory process, which may offset the impact of the relief from stress testing and risk management requirements provided by the Economic Growth Act.

We are subject to complex and evolving laws, regulations, rules, standards and contractual obligations regarding data privacy and cybersecurity, which can increase the cost of doing business, compliance risks, and potential liability.

We are subject to complex and evolving laws, regulations, rules and standards governing the privacy and protection of personal information of individuals. Such individuals include our customers, our employees, and the employees of our vendors, counterparties and other third parties with which we do business. Ensuring that our collection, use, transfer, storage and other processing of personal information complies with applicable laws, regulations, rules and standards regarding data privacy and cybersecurity in relevant jurisdictions can increase operating costs, impact the development of new products or services, and reduce operational efficiency. Any actual or perceived mishandling or misuse of personal information by HTLF or a third party affiliated with HTLF could expose us to litigation, regulatory fines, penalties or other sanctions, reputational harm, and other adverse impacts.

At the federal level, we are subject to the GLBA, which requires financial institutions to, among other things, periodically disclose their privacy policies and practices relating to sharing personal information and, in some cases, enables retail customers to opt out of the sharing of certain personal information with unaffiliated third parties. The GLBA also requires financial institutions to implement an information security program which is overseen by the HTLF Risk Committee that includes administrative, technical and physical safeguards to ensure the security and confidentiality of customer records and information. Additionally, like other lenders, HTLF Bank uses credit bureau data in its underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act ("FCRA"), and the FCRA also regulates reporting information to credit bureaus, prescreening individuals for credit offers, sharing of information between affiliates, and using affiliate data for marketing purposes. We are also subject to the rules and regulations promulgated under the authority of the Federal Trade Commission, which regulates unfair or deceptive acts or practices, including with respect to data privacy and cybersecurity. Moreover, the United States Congress has recently considered, and is currently considering, various proposals for more comprehensive data privacy and cybersecurity legislation, to which we may be subject if passed. Additionally, the federal banking regulators, as well as the SEC and related self-regulatory organizations, regularly issue guidance regarding cybersecurity that is intended to enhance cyber risk management among financial institutions.

Data privacy and cybersecurity are also areas of increasing state legislative focus, and we are, or may in the future become, subject to various state laws and regulations regarding data privacy and cybersecurity. For example, the California Consumer Protection Act of 2018 (the "CCPA"), which became effective on January 1, 2020, applies to for-profit businesses that conduct business in California and meet certain revenue or data collection thresholds. The CCPA gives California residents the right to, among other things, request disclosure of information collected about them and whether that information has been sold to others, request deletion of personal information (subject to certain exceptions), opt out of the sale of their personal information, and not be discriminated against for exercising these rights. The CCPA contains several exemptions, including an exemption applicable to personal information that is collected, processed, sold or disclosed pursuant to the GLBA. In addition, the California Privacy Rights Act ("CPRA") which went into effect on January 1, 2023, significantly modifies the CCPA, including by expanding California residents’ rights with respect to certain sensitive personal information. The CPRA also creates a new state agency which will be vested with authority to implement and enforce the CCPA and the CPRA. Other states where we do business, or may in the future do business, or from which we otherwise collect, or may in the future otherwise collect, personal information of residents have adopted or are considering adopting similar laws. In addition, laws in all 50 U.S. states generally require businesses to provide notice under certain circumstances to consumers whose personal information has been disclosed as a result of a data breach. Certain state laws and regulations may be more stringent, broader in scope, or offer greater individual rights, with respect to personal information than federal or other state laws and regulations, and such laws and regulations may differ from each other, which may complicate compliance efforts and increase compliance costs. Aspects of the CCPA, the CPRA, and other federal and state laws and regulations relating to data privacy and cybersecurity, as well as their enforcement, remain unclear, and we may be required to modify our practices to comply with them.

While we strive to publish and prominently display privacy policies that are accurate, comprehensive, and compliant with applicable laws, regulations, rules and industry standards, we cannot ensure that our privacy policies and other statements regarding our practices will be sufficient to protect us from claims, proceedings, liability or adverse publicity relating to data privacy or cybersecurity. Although we endeavor to comply with our privacy policies, we may at times fail to do so or be alleged to have failed to do so. The publication of our privacy policies and other documentation that provide promises and assurances about privacy, data protection and cybersecurity can subject us to potential federal or state action if they are found to be deceptive, unfair, or misrepresentative of our actual practices. Additional risks could arise in connection with any failure or perceived failure by us, our vendors or other third parties with which we do business to provide adequate disclosure or transparency to our customers about the personal information collected from them and its use, to receive, document or honor the privacy preferences expressed by our customers, to protect personal information from unauthorized disclosure, or to maintain proper training on privacy practices for all employees or third parties who have access to personal information in our possession or control.

Any failure or perceived failure by us to comply with our privacy policies, or applicable data privacy and cybersecurity laws, regulations, rules, standards or contractual obligations, or any compromise of security that results in unauthorized access to, or unauthorized loss, destruction, use, modification, acquisition, disclosure, release or transfer of personal information, may result in requirements to modify or cease certain operations or practices, the expenditure of substantial costs, time and other resources, proceedings or actions against us, legal liability, governmental investigations, enforcement actions, claims, fines, judgments, awards, penalties, sanctions and costly litigation (including class actions), and may result in restrictions on our future activities, including acquisitions. Any of the foregoing could harm our reputation, distract our management and technical personnel, increase our costs of doing business, adversely affect the demand for our products and services, and ultimately result in the imposition of liability, any of which could have a material adverse effect on our business, financial condition and results of operations.

Litigation and enforcement actions could result in negative publicity and could adversely impact our business and financial results.

We face significant legal and regulatory risks in our business, and the volume of claims and amount of damages and penalties claimed in litigation and governmental proceedings against financial institutions have increased in recent years. Current public uneasiness with the United States banking system heightens this risk, and news regarding consumer fraud, financial difficulties or even failure of some institutions, to fear of fraud, financial difficulty or failure of even the most secure institutions has exacerbated these fears and, in some cases, led to rapid withdrawal of deposits at financial institutions. Any negative news may result in the loss of business relationships, withdrawal by customers of deposits, or other actions that could materially adversely affect our liquidity, operations, and financial condition.

The financial services industry has increasingly been targeted by lawsuits alleging infringement of patent rights. Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any claims by potential or actual litigants, we may have to engage in protracted and costly litigation which may be time consuming and disruptive to our operations and management. If we are found to infringe on one or more patents or other intellectual property rights, we may be required to pay substantial damages or royalties to a third-party or may be subject to a temporary or permanent injunction prohibiting us from utilizing certain technologies.

Substantial legal liability or significant governmental action against us could materially impact our business and financial results, and the resolution of litigation or regulatory matters could result in additional accruals or exceed established accruals for a particular period, which could materially impact our financial condition or results of operations.

Our reputation and our business are subject to negative publicity risk.

Reputation risk, or the risk to our earnings and capital from negative public opinion, is inherent in our business. Negative public opinion could adversely affect our ability to keep and attract customers and expose us to adverse legal and regulatory consequences. Negative public opinion could result from our actual or alleged conduct in any number of activities, including lending practices, corporate governance, regulatory compliance, mergers and acquisitions, and disclosure, sharing or inadequate protection of customer information, and from actions taken by government regulators and community organizations in response to that conduct.

Risks of Owning Stock in HTLF

Our stock price can be volatile and can be affected by a variety of factors that are outside of our control.

Our stock price can fluctuate widely in response to a variety of factors, including: actual or anticipated variations in our quarterly operating results; recommendations by securities analysts; acquisitions or business combinations; capital commitments by or involving HTLF or HTLF Bank; operating and stock price performance of other companies that investors deem comparable to us; new technology used or services offered by our competitors; new reports relating to trends, concerns and other issues in the financial services industry; and changes in government regulations. General market fluctuations, specific banking industry issues, and general economic and political conditions and events have caused a decline in our stock price in the past, and these factors, as well as, rapid interest rate changes, unfavorable credit loss trends, or unforeseen events such as geopolitical events or terrorist attacks could cause our stock price to be volatile regardless of our operating results.

Stockholders may experience dilution as a result of future equity offerings and acquisitions.

We may issue equity or other securities convertible into or exchangeable for our common stock to stockholders of companies we acquire, to the public in order to raise capital for future acquisitions, or for general corporate purposes. Such issuances may be at a price per share that may be lower than the current price or per share book value of our common stock. This could have a substantial dilutive effect on existing stockholders. In addition, investors purchasing shares or other securities in the future could have rights superior to existing stockholders.

Certain banking laws may have an anti-takeover effect.

Certain federal banking laws, including regulatory approval requirements, could make it more difficult for a third-party to acquire HTLF, even if doing so would be perceived to be beneficial to HTLF’s stockholders.

ITEM 1B. UNRESOLVED STAFF COMMENTS

As of December 31, 2023, HTLF had no unresolved staff comments.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

HTLF Bank's Risk Management program is designed to identify, assess, monitor and mitigate risks based on various key risk factors we face including, but not limited to financial, operational, regulatory and legal. Cybersecurity is a critical component of our risk management framework given internal dependencies on technology, the evolving digital environment and the rapid acceleration of cyber-threats. HTLF’s cybersecurity risk management program is built on three lines of defense Risk Management framework. HTLF’s first line of defense provides frontline business, operational and technical controls and support to securely deliver access to HTLF applications and data to HTLF users. As part of the Risk Management function, HTLF’s second line of defense is primarily responsible for infrastructure defense and security controls, performing vulnerability assessments, identity access management, business continuity, third-party information security assessments, employee awareness and training programs, and security incident management. Internal Audit functions as HTLF’s third line of defense and independently provides assurance, via multiple audit and testing engagements to validate the effectiveness of HTLF's cybersecurity risk management practices, while measuring against regulatory requirements and HTLF’s Policies and Standards.

HTLF’s first line of defense is led by our Chief Operations Officer and our Chief Information Officer. HTLF’s second line of defense is led by our Chief Risk Officer ("CRO") and includes the Security function, led by our Chief Information Security Officer ("CISO") who is primarily responsible for the cybersecurity component. The primary responsibilities of the HTLF Security function are to protect HTLF assets including networks, systems, application, data, funds, and staff, and facilitate incident response and resolution. HTLF’s third line of defense is led by our Chief Audit Executive.

Our primary objectives for managing cybersecurity risk are to avoid or minimize the impacts of external threat events or other efforts to penetrate, disrupt, exploit or misuse our information or systems. The structure of our information security program is designed around the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, regulatory guidance, and other industry standards. The NIST cybersecurity framework is a nationally recognized industry standard for mitigating organizational cybersecurity risks, which includes identifying risks, protecting assets, detecting threats, responding to incidents, and recovery from incidents. The NIST cybersecurity framework uses standards, procedures and best practices, and is integrated into the HTLF Security team’s overall risk management system and processes, including oversight of third-party service providers. Management of the HTLF's third parties, including vendors and service providers, is conducted through a risk-based approach and the level of due diligence is driven from risk factors established by Enterprise Risk Management through its Third Party Risk Management Program. The process provides awareness and collaboration across all internal teams including Information Security and Business Continuity. A technical requirements review process is conducted on new or significantly changed third parties, applications, or technology to ensure that systems or third parties meet certain security baseline requirements. Further, HTLF's Security program also provides for annual mandatory training for employees regarding security awareness and understanding of how to properly use and protect the company assets, including computing resources entrusted to them, and to communicate the company's information security policies, standards, processes and practices.

To address evolving cybersecurity risks and corresponding regulations, the HTLF Security team uses Federal Financial Institutions Examination Council ("FFIEC") booklets and Cybersecurity and Infrastructure Agency ("CISA") guidance; identifies and defines emerging risks using third-party research and subject matter expert consultants; executes strategic cyber threat assessments; performs new product and initiative reviews; performs data management risk oversight; and conducts cyber risk reviews as part of HTLF’s Third Party Risk Management process, which oversees and identifies risks, including cybersecurity threats, associated with our use of third-party service providers. The HTLF Security team conducts periodic tabletop exercises to test HTLF business units’ capabilities to respond to various security incidents, including cyber-attacks.

Governance

Our CISO is accountable for managing our enterprise information security department and delivering our information security program. The responsibilities of this department include cybersecurity governance (policies and procedures), risk assessment, defense operations, incident response, vulnerability monitoring, threat intelligence, identity access governance, information security/cyber related third-party risk management, and business continuity. Moreover, the Security function is responsible for assessing, managing and remediating material risks from cybersecurity threats. The Security management team has the

technical, management and project leadership experience in mid-sized or larger banks, maintains appropriate technical certifications, and stay abreast of industry, technical and regulatory best practices and requirements.

If a cybersecurity event occurs, the CISO leads the HTLF Incident Response Team as part of our Incident Response Plan designed to help reduce the risks related to security incidents by providing guidelines on responding to incidents by focusing on a roadmap for coordinating personnel, policies, and procedures to ensure incidents are detected, analyzed, and handled to mitigate material risks. The CISO and CRO work with key cross functional stakeholders, including members of executive leadership and provide updates to the HTLF Risk Committee on the status and impact of the cybersecurity event, as well as review the event with the Risk Committee following its ultimate resolution in order to share root cause and lessons learned from the incident.

HTLF has implemented a robust corporate governance framework comprised of the HTLF Board of Directors and its committees; which in turn delegate authority to management for implementation of the risk management program including cybersecurity as an integral component. The corporate governance framework is designed to provide transparency through routine reporting as provided by the CISO to facilitate effective oversight of cybersecurity risk by the Board and executive management. The management committee layer of the corporate governance framework is supported by an Operational Risk Committee which serves as a key forum for the CISO to report quarterly updates on HTLF's cybersecurity risk profile, key metrics and risk indicators used to monitor the operating environment, emerging risks and threats as well as any cybersecurity incidents or events. In addition, the CISO has a routine reporting cadence with the Executive Risk Management Committee and the HTLF Risk Committee on the status of the cyber security management program, including trending of key risk metrics, results of risk assessments, audits and regulatory examinations.

HTLF has not been materially affected by any cyber security incidents to date, nor are we aware of any cyber security incident which we believe would have a material impact on us in the future. Nevertheless, like all financial institutions, we are subject to the risk that cybersecurity threats will continue to evolve and may materially impact us in the future. These factors are further detailed in the "Risk Factors" section included under Item 1A of Part I of this Annual Report on Form 10-K, including under the caption “Security breaches, cyber-attacks or other similar incidents with respect to our or our vendors’ systems or network security, as well as the resulting theft or compromise of business and customer information, including personal information, could adversely affect our business or reputation, and create significant legal, regulatory or financial exposure.”

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s discussion and analysis of the consolidated financial condition and results of operations of HTLF as of the dates and for the periods indicated is presented below. This discussion should be read in conjunction with the consolidated financial statements and the notes thereto and other financial data appearing elsewhere in this Annual Report on Form 10-K. The consolidated financial statements include the accounts of HTLF and its subsidiaries, all of which are wholly-owned.

For a discussion of 2022 results of operations, including a discussion of the financial results for the fiscal year ended December 31, 2022, compared to the fiscal year ended December 31, 2021, refer to Part I, Item 7 of our Annual Report on Form 10-K, which was filed with the SEC on February 23, 2023.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, income and expenses. These estimates are based upon historical experience and on various other assumptions that management believes are reasonable under the circumstances. Among other things, the estimates form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Refer to Note One, "Summary of Significant Accounting Policies," for further discussion on HTLF's critical accounting policies.

The estimates and judgments that management believes have the most effect on HTLF’s reported financial position and results of operations are as follows:

Allowance For Credit Losses

The process utilized by HTLF to estimate the allowance for credit losses is considered a critical accounting estimate for HTLF. The allowance for credit losses represents management’s estimate of identified and unidentified current expected credit losses in the existing loan portfolio. Therefore, the accuracy of this estimate could have a material impact on HTLF’s earnings.

For certain commercial and agricultural loans and any related unfunded loan commitments, the expected credit losses are calculated on a pool basis through a transition matrix model derived life of loan probability of default and loss given default methodology. The probability of default and loss given default methodology have been developed using HTLF’s historical loss experience over the look back period, currently over the most recent 16 years. For smaller commercial and agricultural loans, residential real estate loans and consumer loans and any related unfunded loan commitments, a lifetime average historical loss rate is established for each pool of loans based upon an average loss rate calculated using HTLF historical loss experience over the look back-period. The loss rates used in the allowance calculation are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks.

If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. All individually assessed loan calculations are completed at least semi-annually.

HTLF's allowance methodology also has a qualitative component, the purpose of which is to provide management with a means to take into consideration changes in current conditions that could potentially affect the level of recognized loan losses, that, for whatever reason, may not be represented in the quantitative analysis performed in determining its base loan loss rates.

Additionally, our allowance calculation utilizes an overlay approach for its economic forecasting component, similar to the method utilized for the qualitative factors. The length of the reasonable and supportable forecast period is a judgmental determination based on the level to which HTLF can reasonably support its forecast of economic conditions that drive its estimate of expected loss.

The economic indices utilized from the economic forecast include the national unemployment rate, national gross domestic product, capacity index manufacturing growth, commercial real estate price indexes, national home price index and the national farm products price index. The economic indices utilized in the calculation which may be the most sensitive in the allowance calculation are the national unemployment rate and the national gross domestic product because management believes changes in these indices, positive or negative, will be impactful to all loan pools.

The appropriateness of the allowance for credit losses is monitored on an ongoing basis by the credit administration group, loan review staff, executive and senior management and the boards of directors of HTLF and HTLF Bank. There can be no assurances that the allowance for credit losses will be adequate to cover all current expected credit losses, but management believes that the allowance for credit losses was appropriate at December 31, 2023. While management uses available information to provide for credit losses, the ultimate collectability of a substantial portion of the loan portfolio and the need for future additions to the allowance will be based on changes in economic conditions.

Should economic conditions deteriorate, borrowers may experience financial difficulty, and the level of nonperforming loans, charge-offs, and delinquencies could rise and require further increases in the provision for credit losses. Conversely, improvement in credit quality and economic conditions may allow for a reduction of provision for credit losses. Any unanticipated changes could have a significant impact on the results of operations.

In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance for credit losses carried by HTLF Bank. Such agencies may require us to make additional provisions to the allowance based upon their judgment about information available to them at the time of their examinations.

Business Combinations, Goodwill and Core Deposit Intangibles

We record all assets and liabilities purchased in an acquisition, including intangibles, at fair value. Determining the fair value of assets and liabilities acquired often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include the use of estimates. Goodwill and indefinite-lived assets are not amortized but are subject to, at a minimum, annual tests for impairment. In certain situations, interim impairment tests may be required if events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Core deposit intangible assets are amortized over their estimated useful lives using straight-line and accelerated methods and are subject to impairment if events or circumstances indicate a possible inability to realize the carrying amount.

The initial fair value measurement of loans and core deposit intangibles require us to make subjective judgments concerning estimates of how the acquired assets will perform in the future using valuation methods. The fair value of acquired loans is based on a discounted cash flow methodology that projects principal and interest payments using key assumptions related to the discount rate and loss rates. The fair value of core deposit intangibles is based on the cost savings approach under a discounted cash flow methodology, whereby projected net cash flow benefits are derived from estimating costs to carry deposits compared to alternative funding costs, and includes key assumptions related to the discount rate, deposit attrition rates and net costs, including discounted cash flow analyses. Events and factors that may significantly affect the estimates include, among others, competitive forces, customer behaviors, changes in revenue growth trends, cost structures, technology, changes in discount rates, and market conditions. In determining the reasonableness of cash flow estimates, HTLF reviews historical performance of the underlying assets or similar assets in an effort to assess and validate assumptions utilized in its estimates.

OVERVIEW

HTLF is a bank holding company operating under the brand name "HTLF" and provides banking, wealth management, investment and retirement plan services to businesses and consumers. HTLF's independently branded Bank Divisions serve communities in Arizona, California, Colorado, Illinois, Iowa, Kansas, Minnesota, Missouri, Montana, New Mexico, Texas and Wisconsin from 117 locations as of December 31, 2023. Our primary objectives are to increase profitability, support our communities and grow our customer base through organic loan and deposit growth in markets we serve.

Our results of operations depend primarily on net interest income, which is the difference between interest income from interest earning assets and interest expense on interest bearing liabilities. Noninterest income, which includes service charges and fees, loan servicing income, trust fees, brokerage and insurance commissions, net securities gains/(losses), net gains on sale of loans held for sale, capital markets fees and income on bank owned life insurance also affect our results of operations. Our principal operating expenses, aside from interest expense, consist of the provision for credit losses, salaries and employee benefits, occupancy, furniture and equipment costs, professional fees, FDIC insurance assessments, advertising, core deposit intangibles and customer relationship intangibles amortization, other real estate and loan collection expenses, partnership investment in tax credit projects and acquisition, integration and restructuring costs.

HTLF Response to Banking Industry Disruptions

The banking industry experienced significant disruptions in March 2023, including bank failures, which has since caused industry-wide concerns related to deposit outflows, liquidity, continued interest rate increases and unrealized losses on securities. In response to the concerns, management continues to:

•help customers facilitate additional FDIC insurance through Insured Cash Sweep ("ICS") products and Certificate of Deposit Registry Service ("CDARS") products,

•monitor deposit flows and adjust deposit pricing and customer acquisition incentives to address the highly competitive deposit environment,

•maintain borrowing capacity through various federal programs, including the Federal Reserve Discount Window and the Federal Reserve's Bank Term Funding Program ("BTFP"), which totaled $1.92 billion as of December 31, 2023, of which no balance was drawn, and also including Federal Home Loan Bank ("FHLB") advances, which totaled $1.15 billion as of December 31, 2023, of which $521.2 million was drawn, and

•reduce the investment portfolio through scheduled maturities and selective sales of investments, including the recently executed a balance sheet repositioning, which reduced investments and related wholesale funding by $865.4 million.

As of December 31, 2023:

•61% of HTLF's deposits were insured or collateralized.

•HTLF's capital ratios substantially exceeded well-capitalized regulatory thresholds, and management believes that HTLF would remain well-capitalized in the event that regulatory rules were adopted requiring that unrealized losses in the total investment portfolio be included in the calculation of regulatory capital ratios.

The shift to work-from-home and hybrid work arrangements has caused decreased utilization of and demand for office space. HTLF is actively monitoring its exposure to office space in the non-owner occupied commercial real estate portfolio and securities portfolio. As of December 31, 2023:

•Outstanding loans totaling $424.7 million, with an average loan size of $1.4 million, were collateralized by non-owner occupied office space, which represents 3.5% of the total loans held to maturity and 2.7% of the total loan portfolio by exposure.

•There were no loans collateralized by office space on nonaccrual.

•The collateral consists primarily of multi-tenant, non-central business district properties.

HTLF monitors the risk exposure in the loan portfolio for both industry and geographic concentrations. In response to the increases in fed funds rate to a 23-year high during 2023, HTLF has developed a process to better identify higher credit risk borrowers. This process flags specific risk drivers and identifies borrowers who exhibit indications of risk; including but not limited to, utilization rate increases, risk rating migration, delinquencies and industries with higher risk in recessions including office and medical office space related loans.

2023 Overview

Net income available to common stockholders was $71.9 million, or $1.68 per diluted common share, for the year ended December 31, 2023, compared to $204.1 million or $4.79 per diluted common share for the year ended December 31, 2022. Return on average common equity was 4.19% and return on average assets was 0.40% for the year ended December 31, 2023, compared to 11.74% and 1.08%, respectively, for the year ended December 31, 2022.

Adjusted earnings available to common stockholders (non-GAAP)(1), which excludes losses related to balance sheet repositioning, losses on sale or write-down of assets, FDIC special assessment expense, and restructuring costs, was $193.9 million for the year ended December 31, 2023, compared to $209.5 million for the year ended December 31, 2022, a decrease of $15.6 million or 7%. Adjusted diluted earnings per common share(1) were $4.53 for the year ended December 31, 2023, compared to $4.91 for the year ended December 31, 2022, a decrease of $0.38 or 8%.

Total assets of HTLF were $19.41 billion at December 31, 2023, a decrease of $832.5 million or 4% from December 31, 2022. The decrease in total assets was primarily attributable to a sizeable reduction in the investment portfolio due to the sale of securities for the balance sheet repositioning and amortization during the year. Securities represented 29% of total assets at December 31, 2023, compared to 35% of total assets at December 31, 2022.

Total loans held to maturity were $12.07 billion at December 31, 2023, compared to $11.43 billion at December 31, 2022, which was an increase of $640.3 million or 6%.

Total deposits were $16.20 billion as of December 31, 2023, compared to $17.51 billion as of December 31, 2022, a decrease of $1.31 billion or 7%.

Total wholesale and institutional deposits were $1.35 billion as of December 31, 2023, compared to $2.29 billion as of December 31, 2022, which was a decrease of $943.9 million or 41%.

Common stockholders' equity was $1.82 billion at December 31, 2023, compared to $1.62 billion at December 31, 2022. Book value per common share was $42.69 at December 31, 2023, compared to $38.25 at December 31, 2022. HTLF's unrealized loss on securities available for sale including the unrealized gain on the fair value of security hedges, net of applicable taxes, was $453.7 million at December 31, 2023, compared to an unrealized loss of $619.2 million at December 31, 2022.

During the first quarter of 2023, HTLF reclassified customer swap and loan syndication income (collectively, "capital markets fees") to capital markets fees from other noninterest income on the consolidated statements of income, and all prior periods have been adjusted.

During the second quarter of 2023, HTLF reclassified Federal Deposit Insurance Corporation ("FDIC") insurance premiums to FDIC insurance assessments from professional fees on the consolidated statements of income, and all prior periods have been adjusted.

2023 Developments

Sale of HTLF Retirement Plan Services Recordkeeping and Administration

As of March 29, 2023, Dubuque Bank & Trust, a division of HTLF Bank, entered into an agreement to sell and transfer the recordkeeping and administration services component of HTLF’s Retirement Plan Services business to July Business Services ("July") in order to augment the comprehensive retirement plan solutions offered to clients with enhanced technology and an expanded suite of product offerings that clients expect from a top retirement services provider. The transaction was completed in the second quarter of 2023 resulting in a gain of $4.3 million, which is included in the gain on sales and valuations of assets on the consolidated statements of income.

Sale of First Bank & Trust Mortgage Servicing Rights

On March 31, 2023, First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing rights portfolio, which consisted of approximately 4,500 loans serviced for others with an unpaid principal balance of $698.5 million. First Bank & Trust provided interim servicing of the loans until the transfer date of May 1, 2023.

Goodwill Impairment Testing

Following the banking industry disruption in March 2023, the sustained decline in the share prices of banking industry stock prices, including HTLF's, was deemed to be a triggering event which caused management to perform impairment testing on its goodwill in the second quarter of 2023. Based on the testing and analysis performed, management concluded that none of the goodwill at any of HTLF's reporting units was impaired. HTLF also conducted its annual internal assessment of the goodwill at HTLF or HTLF's reporting units as of September 30. There was no goodwill impairment as of the most recent assessment.

Fair Value Hedges

During the second quarter of 2023, HTLF entered into interest rate swaps designated as fair value hedges with initial notional amounts of $838.1 million primarily designed to provide protection against unrealized securities losses due to the impact of higher mid-to-long term interest rates.

During the second and third quarters of 2023, HTLF also executed interest rate swaps designated as fair value hedges with original notional amounts totaling $2.5 billion to convert certain long term fixed rate loans to floating rates to hedge interest rate risk exposure.

Balance Sheet Repositioning

During the fourth quarter of 2023, as a part of the new HTLF 3.0 strategic initiatives, HTLF sold investment securities with a combined yield of 2.69% in a series of sale transactions, resulting in proceeds totaling approximately $865.4 million and

realized securities losses of $140.0 million or $106.8 million after tax. HTLF utilized the proceeds to reduce its wholesale deposits and short-term borrowings, which carried an interest rate of approximately 5.50%.

These transactions decreased earning assets by approximately $865.4 million during the fourth quarter of 2023. HTLF's net interest income increased $10.4 million from $145.8 million for the third quarter of 2023 to $156.1 million for the fourth quarter of 2023 largely as result of the balance sheet reposition. The common equity ratio increased from 8.16% at December 31, 2022, to 8.49% at September 30, 2023, and 9.27% at December 31, 2023. In addition, the tangible common equity ratio(1) increased from 5.21% at December 31, 2022, to 5.73% at September 30, 2023, and 6.53% at December 31, 2023. Because the securities sold were held on the balance sheet as available for sale, the incurred losses had already been included in calculating tangible common equity.

HTLF will continue to manage its balance sheet and investment portfolio through purchases and/or sales of investments in order to effectively manage its balance sheet and liquidity and interest rate positions.

Charter Consolidation Update

During 2023, Wisconsin Bank & Trust, Bank of Blue Valley, First Bank & Trust, Rocky Mountain Bank, New Mexico Bank & Trust and Dubuque Bank and Trust were consolidated into HTLF Bank, which successfully completed the consolidation of all 11 charters. Total consolidation restructuring costs were $16.9 million, of which $7.3 million was incurred in 2023.

HTLF 3.0

HTLF's new strategic plan, HTLF 3.0, was announced and initiated in the fourth quarter of 2023. HTLF 3.0 is a connected set of initiatives that includes investing in growth through banker expansion and talent acquisition, expanding Treasury Management products and capabilities, enhancement of consumer and small business digital platforms, and footprint and facilities optimization. As part of these initiatives, in the fourth quarter of 2023, HTLF repositioned its balance sheet, centralized retail management span of control, and took further steps to optimize its facilities.

Common Stock Dividend Increase

The common stock dividend was increased from $0.28 per common share to $0.30 in the first quarter of 2023 and was maintained at this level in all four quarters of 2023.

Subsequent Events

Planned Retirement of Chief Executive Officer

On February 13, 2024, Bruce K. Lee, the Company’s President and Chief Executive Officer (“CEO”), and a member of the Board of Directors (the “Board”), informed the Board that he intends to retire by the end of 2024. Mr. Lee has agreed that he will continue to serve as the Company’s CEO until his successor is chosen and assumes the role of CEO, and will assist in the transition and retire from the Company at the end of the year. Mr. Lee also indicated that concurrent with his successor assuming the role of CEO of the Company, he intends to retire from the Board. The Board has formed a search committee and will use Heidrick & Struggles, a nationally recognized executive recruiting firm, to begin a nationwide search for Mr. Lee’s successor.

Sale of Rocky Mountain Bank

Subsequent to December 31, 2023, in February of 2024, HTLF Bank signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024. The sales are expected to improve capital and increase the efficiency of HTLF's footprint, aligning with HTLF 3.0.

2022 Overview

Net income available to common stockholders was $204.1 million, or $4.79 per diluted common share, for the year ended December 31, 2022, compared to $211.9 million or $5.00 per diluted common share for the year ended December 31, 2021. Return on average common equity was 11.74% and return on average assets was 1.08% for the year ended December 31, 2022, compared to 10.49% and 1.19%, respectively, for the year ended December 31, 2021.

Total loans held to maturity were $11.43 billion at December 31, 2022, compared to $9.95 billion at December 31, 2021, which was an increase of $1.47 billion or 15%. Excluding total PPP loans, total loan held to maturity increased $1.66 billion or 17% since year end 2021.

Total deposits were $17.51 billion as of December 31, 2022, compared to $16.42 billion as of December 31, 2021, an increase of $1.10 billion or 7%.

Common stockholders' equity was $1.62 billion at December 31, 2022, compared to $2.07 billion at December 31, 2021. Book value per common share was $38.25 at December 31, 2022, compared to $49.00 at December 31, 2021. HTLF's unrealized gains and losses on securities available for sale, net of applicable taxes, reflected an unrealized loss of $619.2 million compared to an unrealized loss of $4.4 million at December 31, 2021.

2022 Developments

Charter Consolidation Update

In the fourth quarter of 2021, the HTLF Board of Directors unanimously approved a plan to consolidate its 11 bank charters. In the second quarter of 2022, the consolidation project advanced from planning to execution with Citywide Banks' initial consolidation into an operating division of HTLF Bank. During the remainder of 2022, the charters of Premier Valley Bank, Minnesota Bank & Trust, Arizona Bank & Trust and Illinois Bank & Trust were consolidated into HTLF Bank, operating as divisions of HTLF Bank. Charter consolidation utilized an operating model that retains the current brands, local leadership and local decision making.

Charter consolidation is designed to eliminate redundancies and improve HTLF’s operating efficiency and capacity to support ongoing product and service enhancements, as well as current and future growth, while enriching the customer experience. HTLF started to realize operating efficiencies and financial benefits in the second half of 2022 with the completion of five charter consolidations.

Common Stock Dividend Increase

The common stock dividend was increased from $0.27 per common share for the first three quarters of 2022 to $0.28 per common share for the fourth quarter of 2022.

Branch Optimization

During 2022, HTLF reduced its branch footprint from 130 to 119 locations, which was a reduction of 11 locations or 8%. HTLF continues to review its franchise network for optimization and consolidation opportunities, which may result in additional write-downs of fixed assets in future periods.

Non-GAAP Financial Measures

This Annual Report on Form 10-K contains references to financial measures which are not defined by generally accepted accounting principles ("GAAP"). Management believes the non-GAAP measures are helpful for investors to analyze and evaluate HTLF's financial condition and operating results. However, these non-GAAP measures have inherent limitations and should not be considered a substitute for operating results determined in accordance with GAAP. Additionally, because non-GAAP measures are not standardized, it may not be possible to compare the non-GAAP measures presented in this section with other companies' non-GAAP measures. Reconciliations of each non-GAAP measure to the most directly comparable GAAP measure may be found in the financial tables above.

The non-GAAP measures presented in this Annual Report on Form 10-K, management's reason for including each measure and the method of calculating each measure are presented below:

•Adjusted earnings available to common stockholders, adjusts net income for the loss/(gain) from sale of securities, and other non-operating expenses as well as the tax effect of those transactions. Management believes this measure enhances the comparability net income available to common stockholders as it reflects adjustments commonly made by management, investors and analysts to evaluate the ongoing operations and enhance comparability with the results of prior periods.

•Adjusted annualized return on average assets, adjusts net income for the loss/(gain) from sale of securities, and other non-operating expenses as well as the tax effect of those transactions. Management believes this measure enhances the comparability of annualized return on average assets as it reflects adjustments commonly made by management, investors and analysts to evaluate the ongoing operations and enhance comparability with the results of prior periods.

•Adjusted annualized return on average common equity, adjusts net income for the loss/(gain) from sale of securities, and other non-operating expenses as well as the tax effect of those transactions. Management believes this measure enhances the comparability of annualized return on average assets as it reflects adjustments commonly made by management, investors and analysts to evaluate the ongoing operations and enhance comparability with the results of prior periods.

•Tangible book value per common share is total common equity less goodwill and core deposit and customer relationship intangibles, net, divided by common shares outstanding, net of treasury. This measure is included as it is considered to be a critical metric to analyze and evaluate use of equity, financial condition and capital strength.

•Tangible common equity ratio is total common equity less goodwill and core deposit and customer relationship intangibles, net, divided by total assets less goodwill and core deposit and customer relationship intangibles, net. This measure is included as it is considered to be a critical metric to analyze and evaluate financial condition and capital strength.

•Annualized return on average tangible common equity is net income excluding intangible amortization calculated as (1) net income excluding tax-effected core deposit and customer relationship intangibles amortization, divided by (2) average common equity less goodwill and core deposit and customer relationship intangibles, net. This measure is included as it is considered to be a critical metric to analyze and evaluate use of equity, financial condition and capital strength.

•Adjusted annualized return on average tangible common equity, adjusts net income available to common stockholders for the loss/(gain) from sale of securities, and other non-operating expenses as well as the tax effect of those transactions. Management believes this measure enhances the comparability of annualized return on average assets as it reflects adjustments commonly made by management, investors and analysts to evaluate the ongoing operations and enhance comparability with the results of prior periods.

•Net interest income, fully tax equivalent, is net income adjusted for the tax-favored status of certain loans and securities. Management believes this measure enhances the comparability of net interest income arising from taxable and tax-exempt sources.

•Annualized net interest margin, fully tax-equivalent, adjusts net interest income for the tax-favored status of certain loans and securities. Management believes this measure enhances the comparability of net interest income arising from taxable and tax-exempt sources.

•Adjusted efficiency ratio, fully tax equivalent, expresses adjusted noninterest expenses as a percentage of fully tax-equivalent net interest income and adjusted noninterest income. This adjusted efficiency ratio is presented on a tax-equivalent basis which adjusts net interest income and noninterest expenses for the tax favored status of certain loans, securities, and tax credit projects. Management believes the presentation of this non-GAAP measure provides supplemental useful information for proper understanding of the financial results as it enhances the comparability of income and expenses arising from taxable and nontaxable sources and excludes specific items as noted in the reconciliation contained in this Annual Report on Form 10-K.

•Annualized ratio of core expenses to average assets adjusts noninterest expenses to exclude specific items noted in the reconciliation. Management includes this measure as it is considered to be a critical metric to analyze and evaluate controllable expenses related to primary business operations.

RESULTS OF OPERATIONS

Net Interest Margin and Net Interest Income

HTLF's management seeks to optimize net interest income and net interest margin through the growth of earning assets and customer deposits while managing asset and liability positions to maximize HTLF's profitability.

Net interest income is the difference between interest income earned on earning assets and interest expense paid on interest

bearing liabilities. As such, net interest income is affected by changes in the volume of and yields on earning assets, and the volume of and rates paid on interest bearing liabilities. Net interest margin is the ratio of net interest income to average earning assets.

See "Analysis of Average Balances, Tax-Equivalent Yields and Rates" for a description of our use of net interest income and net interest margin on a fully tax-equivalent basis, which is not defined by GAAP, and a reconciliation of annualized net interest margin on a fully tax-equivalent basis to GAAP.

Net interest margin, expressed as a percentage of average earning assets, was 3.29% (3.33% on a fully tax-equivalent basis, non-GAAP) during 2023, compared to 3.32% (3.37% on a fully tax-equivalent basis, non-GAAP) during 2022 and 3.29% (3.33% on a fully tax-equivalent basis, non-GAAP) during 2021.

Net interest margin for the year ended December 31, 2023, compared to the year ended December 31, 2022

Total interest income and average earning asset changes for 2023 compared to 2022 were:

•Total interest income increased $279.1 million or 41% to $953.8 million from $674.7 million, which was primarily attributable to higher yields and an increase in average loans.

•Total interest income on a tax-equivalent basis (non-GAAP) was $962.4 million compared to $683.1 million, which was an increase of $279.3 million or 41%.

•Average earning assets increased $280.1 million or 2% to $18.30 billion from $18.02 billion, which was primarily attributable to loan growth, which was offset by a reduction in securities balances.

•The average rate on earning assets increased 147 basis points to 5.26% compared to 3.79%, which was primarily due to recent increases in market interest rates and a shift in earning asset mix.

Total interest expense and average interest-bearing liability changes for 2023 compared to 2022 were:

•Total interest expense increased $276.1 million to $352.6 million compared to $76.4 million.

•The average rate paid on HTLF's interest bearing liabilities increased 206 basis points to 2.73% compared to 0.67%, which was primarily due to recent increases in market interest rates, competition for deposits, and deposit mix changes.

•Average interest-bearing deposits increased $1.44 billion or 13% to $12.34 billion from $10.90 billion. The increase was primarily due to the increase in average wholesale deposits, which totaled $2.52 billion compared to $1.21 billion.

•The average rate paid on HTLF's interest bearing deposits increased 206 basis points to 2.59% compared to 0.52%, which was primarily attributable to recent increases in market interest rates.

•Average borrowings increased $36.4 million or 7% to $576.7 million from $540.3 million. The average interest rate paid on HTLF's borrowings was 5.70% compared to 3.62%.

Net interest income changes for 2023 compared to 2022 were:

•Net interest income totaled $601.2 million compared to $598.2 million, which was an increase of $3.0 million or 1%.

•Net interest income on a tax equivalent basis (non-GAAP) totaled $609.8 million compared to $606.6 million, which was an increase of $3.2 million or 1%.

Net interest margin for the year ended December 31, 2022, compared to the year ended December 31, 2021

Total interest income and average earning asset changes for 2022 compared to 2021 were:

•Total interest income increased $85.9 million or 15% to $674.7 million from $588.8 million, which was primarily attributable to an increase in average earning assets and an increase in the average rate on earning assets.

•Total interest income on a tax-equivalent basis (non-GAAP) was $683.1 million compared to $596.0 million, which was an increase of $87.1 million or 15%.

•Average earning assets increased $996.0 million or 6% to $18.02 billion from $17.03 billion, which was primarily attributable to loan growth.

•The average rate on earning assets increased 29 basis points to 3.79% compared to 3.50%, which was primarily due to recent increases in market interest rates and a shift in earning asset mix.

Total interest expense and average interest-bearing liability changes for 2022 compared to 2021 were:

•Total interest expense increased $48.2 million to $76.4 million compared to $28.2 million.

•The average rate paid on HTLF's interest bearing liabilities increased 39 basis points to 0.67% compared to 0.28%, which was primarily due to recent increases in market interest rates and deposit growth, including wholesale funding.

•Average interest-bearing deposits increased $1.45 billion or 15% to $10.90 billion from $9.45 billion. Average wholesale deposits totaled $1.02 billion compared to $5.2 million.

•The average rate paid on HTLF's interest bearing deposits increased 36 basis points to 0.52% compared to 0.16%, which was primarily attributable to recent increases in market interest rates.

•Average borrowings increased $19.4 million or 4% to $540.3 million from $520.9 million. The average interest rate paid on HTLF's borrowings was 3.62% compared to 2.57%.

Net interest income changes for 2022 compared to 2021 were:

•Net interest income totaled $598.2 million compared to $560.6 million, which was an increase of $37.7 million or 7%.

•Net interest income on a tax equivalent basis (non-GAAP) totaled $606.6 million compared to $567.8 million, which was an increase of $38.9 million or 7%.

HTLF's future net interest margin may be impacted by several factors including changes in market interest rates driven by the Federal Reserve, our ability to grow customer deposits to replace wholesale deposits, pressure on deposit pricing due to competition, and our ability to utilize cash flow from the investment portfolio to reduce wholesale deposits and borrowings. Management anticipates utilizing cash flow from the investment portfolio to pay down wholesale deposits and short-term borrowings to improve net interest margin. In 2023, the Federal Reserve increased the federal funds rate four times for a total of 100 basis points to a 23-year high. The Federal Reserve has indicated it will closely assess economic data, but has signaled it may reduce the Federal funds interest rate in the latter half of 2024. Ultimately, the timing and magnitude of any such changes are uncertain and will depend on domestic and global economic conditions.

We attempt to manage our balance sheet to minimize the effect that a change in interest rates has on our net interest income. We continue to work toward improving both our earning assets and funding mix through targeted organic growth strategies, which we believe will result in additional net interest income. We model and review simulations using various improving and deteriorating interest rate scenarios to assist in monitoring our exposure to interest rate risk. We believe our net interest income simulations reflect a well-balanced and manageable interest rate posture. Item 7A of this Annual Report on Form 10-K contains additional information about the results of our most recent net interest income simulations. Note Eleven, "Derivative Financial Instruments" to the consolidated financial statements contains a detailed discussion of the derivative instruments we have utilized to manage interest rate risk.

The following table provides certain information relating to our average consolidated balance sheets and reflects the yield on average earning assets and the cost of average interest-bearing liabilities for the years indicated, in thousands. Dividing income or expense by the average balance of assets or liabilities derives such yields and costs. Average balances are derived from daily balances, and nonaccrual loans and loans held for sale are included in each respective loan category. Assets with tax favorable treatment are evaluated on a tax-equivalent basis assuming a federal income tax rate of 21%. Tax favorable assets generally have lower contractual pre-tax yields than fully taxable assets. A tax-equivalent yield is calculated by adding the tax savings to the interest earned on tax favorable assets and dividing by the average balance of the tax favorable assets.

The following table presents the dollar amount of changes in interest income and interest expense for the major components of interest earning assets and interest-bearing liabilities, in thousands. It quantifies the changes in interest income and interest expense related to changes in the average outstanding balances (volume) and those changes caused by fluctuating interest rates. For each category of interest earning assets and interest bearing liabilities, information is provided on changes attributable to (i) changes in volume, calculated by multiplying the difference between the average balance for the current period and the average balance for the prior period by the rate for the prior period, and (ii) changes in rate, calculated by multiplying the difference between the rate for the current period and the rate for the prior period by the average balance for the prior period. The unallocated change has been allocated pro rata to volume and rate variances.

PROVISION FOR CREDIT LOSSES

A provision for credit losses is charged to expense to provide, in HTLF management’s opinion, an appropriate allowance for credit losses. The following table shows the components of HTLF's provision for credit losses for the years ended December 31, 2023, 2022 and 2021, in thousands:

	For the Years Ended December 31,
	2023		2022		2021
Provision (benefit) for credit losses-loans	$	25,435	$	10,636	$	(17,706)
Provision (benefit) for credit losses-unfunded commitments	(3,728)		4,734		182
Provision (benefit) for credit losses-held to maturity securities	—		—		(51)
Total provision expense (benefit)	$	21,707	$	15,370	$	(17,575)

The provision for credit losses was $21.7 million for 2023 compared to $15.4 million for 2022. The provision expense for 2023 was impacted by several factors, including:

•loan growth, excluding PPP loans which have no associated provision, totaled $648.5 million,

•an increase in nonperforming loans of $39.4 million to $97.9 million or 0.81% of total loans compared to $58.5 million or 0.51% of total loans at December 31, 2022, and

•net charge-offs of $12.4 million.

The provision for credit losses was $15.4 million for 2022 compared to a benefit of $17.6 million for 2021. The provision expense for 2022 was impacted by several factors, including:

•loan growth, excluding PPP loans which have no associated provision, totaled $718.0 million,

•a decrease in nonperforming loans of $11.4 million to $58.5 million or 0.51% of total loans compared to $69.9 million or 0.70% of total loans at December 31, 2021,

•net charge-offs of $11.2 million, and

•utilization of a macroeconomic outlook in the estimation of the allowance for credit losses that anticipates a moderate recession developing within the next twelve months.

At December 31, 2023, the allowance for credit losses for loans was 1.02% of total loans and 125.15% of nonperforming loans compared to 0.96% of total loans and 187.14% of nonperforming loans at December 31, 2022.

The size of the loan portfolio, the level of organic loan growth, government loan guarantees, changes in credit quality, and economic conditions, are all considered when determining the appropriateness of the allowance for credit losses and will contribute to changes in the provision for credit losses from year to year. For additional details on the specific factors considered in establishing the allowance for credit losses, refer to the discussion under the captions "Critical Accounting Estimates," "Provision for Credit Losses" and "Allowance for Credit Losses" in Item 8 of this Annual Report on Form 10-K, and the information in Note One, "Basis of Presentation," and Note Five, "Allowance for Credit Losses" to the consolidated financial statements contained herein.

HTLF believes the allowance for credit losses as of December 31, 2023, was at a level commensurate with the overall risk exposure of the loan portfolio. However, deterioration in economic conditions, including a recession, could cause certain borrowers to experience financial difficulty and impede their ability to make loan payments. Due to the uncertainty of future economic conditions, including ongoing concerns over the impact of higher interest rates, workforce shortages, wage pressures, and the waning effects of the economic stimulus, the provision for credit losses could be volatile in future periods.

NONINTEREST INCOME

The table below summarizes HTLF's noninterest income for the years indicated, in thousands:

Notable changes in the components of noninterest income are as follows:

Service Charges and Fees

The following table summarizes the changes in service charges and fees for the years ended indicated, in thousands:

	For the Years Ended December 31,						% Change
	2023		2022		2021		2023/2022		2022/2021
Service charges and fees on deposit accounts	$	21,037	$	18,625	$	16,414	13	%	13	%
Overdraft fees	11,878		12,136		11,005		(2)		10
Customer service fees	358		375		220		(5)		70
Credit card fee income	31,102		27,560		21,623		13		27
Debit card income	9,649		9,335		10,441		3		(11)
Total service charges and fees	$	74,024	$	68,031	$	59,703	9	%	14	%

Total service charges and fees were $74.0 million in 2023, which was an increase of $6.0 million or 9% from $68.0 million in 2022. Total service charges and fees in 2022 were $68.0 million, which was an increase of $8.3 million or 14% from $59.7 million in 2021.

The increase in credit card income detailed above was primarily the result of a larger commercial credit card base and increased utilization. The changes in debit card income noted above are primarily attributable to an increase in debit interchange volume.

In December 2023, in response to industry changes related to the consumer overdraft fees, HTLF modified its consumer deposit product and fee structure, including overdraft fees. As result, consumer deposit overdraft fees declined $600,000. Management anticipates this decline to be ongoing, and result in approximately $7.2 million lower consumer overdraft fee income in 2024 as compared to 2023.

Loan Servicing Income

Loan servicing income includes the fees collected for the servicing of commercial, agricultural, and mortgage loans, which depend upon the aggregate outstanding balance of these loans, rather than quarterly production and sale of these loans. Total loan servicing income totaled $1.6 million for 2023 compared to $2.7 million for 2022 and $3.3 million for 2021.

Included in and offsetting loan servicing income is the amortization of capitalized mortgage servicing rights, which was $210,000 during 2023 compared to $1.1 million during 2022 and $1.4 million during 2021. In the first quarter of 2023, First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing rights portfolio. Increases in residential mortgage interest rates during 2022 caused mortgage refinancing activity to decrease during the year ended December 31, 2022, which resulted in lower mortgage servicing rights amortization.

Note 7, "Goodwill, Core Deposit Intangibles and Other Intangible Assets," to the consolidated financial statements contains a discussion of our servicing rights.

Trust Fees

Trust fees totaled $20.7 million for the year ended December 31, 2023, a decrease of $1.9 million or 8% from $22.6 million for the year ended December 31, 2022. Trust fees totaled $22.6 million for the year ended December 31, 2022, a decrease of $1.8 million or 8% from $24.4 million for the year ended December 31, 2021. The decrease in 2023 was largely attributable to the sale of the administrative and recordkeeping services component of HTLF's Retirement Plan Services business that was completed in the second quarter of 2023. Retirement plan services income decreased $1.7 million or 27% to $4.6 million in 2023 compared to $6.3 million in 2022. The changes in trust fees are also impacted by changes in the market value of trust assets under management, which were $3.92 billion, $3.62 billion and $3.79 billion at December 31, 2023, 2022, and 2021, respectively.

Capital markets fees

Capital markets fees totaled $10.0 million for the year ended 2023, compared to $11.5 million for the year ended 2022. Syndication income totaled $2.3 million in 2023 compared to $4.9 million for 2022. Swap fee income was $7.7 million in 2023 compared to $6.6 million in 2022.

Capital markets fees vary, in part, based upon the size of the transaction and are recognized upon the closing of the transaction.

Securities (losses) gains, net

Net security losses totaled $141.5 million for the year ended December 31, 2023, compared to net security losses of $425,000 for the year ended December 31, 2022, which was a decrease of $141.1 million. During the fourth quarter of 2023, as previously described, HTLF sold securities to strategically reposition its balance sheet, resulting in a $140.0 million loss.

Net Gains on Sale of Loans Held for Sale

Net gains on sale of loans held for sale totaled $3.9 million during 2023 compared to $9.0 million during 2022 and $20.6 million during 2021. The decrease in 2023 in comparison with 2022 was primarily due to a decrease of loans sold to the secondary market. HTLF elected to significantly scale back mortgage originations, as a result of the decreased customer demand due to the continued challenging rate environment for mortgage loan originations. The decrease in 2022 in comparison with 2021 was largely attributable to increased residential mortgage rates, which caused mortgage loan origination volumes to decline.

Valuation Adjustment on Servicing Rights

The valuation adjustment recovery on servicing rights was $0 for the year ending December 31, 2023, compared to $1.7 million for the year ending December 31, 2022, and compared to $1.1 million for the year ended December 31, 2021. HTLF sold its mortgage servicing rights portfolio in the first quarter of 2023. HTLF recovered its valuation allowance in the first quarter of 2022 due to increases in residential mortgage loan interest rates.

Other noninterest income

Other noninterest income totaled $3.6 million for the year ended December 31, 2023, a decrease of $4.8 million from $8.4 million for the year ended December 31, 2022. The decrease was primarily attributable to gains of $1.9 million recorded in the second quarter of 2022 on the sale of all VISA Class B shares.

NONINTEREST EXPENSES

Total noninterest expenses	$	461,827	$	443,377	$	431,812	4	%	3	%

Notable changes in the components of noninterest expenses are as follows:

Salaries and Employee Benefits

The largest component of noninterest expense, salaries and employee benefits, decreased $3.2 million or 1% to $251.3 million in 2023 and increased $14.4 million or 6% to $254.5 million in 2022. Full-time equivalent employees totaled 1,970 on December 31, 2023, compared to 2,002 on December 31, 2022, and 2,249 on December 31, 2021.

The decrease in salaries and employee benefits during 2023 was primarily attributable to lower incentive compensation expense, which was partially offset by higher salaries expense.

The increase in salaries and employee benefits during 2022 was primarily attributable to higher salaries expense due to inflationary wage pressures and incentive compensation.

FDIC Insurance Assessments

FDIC insurance assessments increased $12.9 million or 185% to $19.9 million in 2023 and $1.2 million or 22% to $7.0 million in 2022. The increase during 2023 was primarily attributable to a one-time special assessment of $8.1 million. In November 2023, the FDIC issued a final rule to implement a special assessment to recover losses to the Deposit Insurance Fund ("DIF") incurred as a result of the early 2023 bank failures and the FDIC's use of the systemic risk exception to cover certain deposits that were otherwise uninsured. The rule provides for a 13.44 basis point annual special assessment on the uninsured deposits reported by HTLF at December 31, 2022, which was $8.03 billion. The special assessment excluded the first $5 billion of uninsured deposits and will be payable over two years.

Advertising

Advertising expense increased $2.1 million or 34% to $8.3 million during 2023 from $6.2 million during 2022, which was primarily driven by deposit acquisition campaigns launched in 2023. During 2022, advertising expense decreased $1.0 million or 14% to $6.2 million from $7.3 million for the year ended December 31, 2021.

Core Deposit Intangibles and Customer Relationship Intangibles Amortization

Core deposit intangibles and customer relationship intangibles amortization totaled $6.7 million during 2023 compared to $7.8 million during 2022, which was a decrease of $1.1 million or 14%. Core deposit intangibles and customer relationship intangibles amortization totaled $7.8 million during 2022 compared to $9.4 million during 2021, which was a decrease of $1.6 million or 17%. The decreases for the years ended December 31, 2023 and 2022 were attributable to the amortization of core deposit intangibles and customer relationship intangibles from recent acquisitions.

(Gain) Loss on Sales/Valuations of Assets, net

Net losses on sales/valuations of assets totaled $77,000 during 2023 compared to net losses on sales/valuations of assets of $1.0 million during 2022 and net gains on sales/valuations of assets of $588,000 during 2021. During 2023, HTLF recorded a gain of $4.3 million associated with the sale of HTLF's Retirement Plan Services recordkeeping and administrative services component. The gain was partially offset by a $1.9 million write-down on one other real estate owned property. HTLF recorded $2.4 million of losses, net, on fixed assets associated with branch optimization activities and a loss of $203,000 associated with the sale of the mortgage servicing rights portfolio.

During 2022, two branches in Illinois were sold for a gain of $3.0 million, and a gain of $413,000 was recorded in conjunction with the sale of an insurance subsidiary. These gains were partially offset by losses and write-downs totaling $1.5 million associated with branch optimization activities.

Acquisition, Integration and Restructuring Expenses

Acquisition, integration and restructuring expenses totaled $10.4 million for the year ended December 31, 2023, which was an increase of $2.8 million or 37% from $7.6 million for the year ended December 31, 2022. The charter consolidation project was completed in the fourth quarter of 2023 with total expenses for 2023 totaling $7.3 million. Additionally, restructuring expenses of $3.1 million were incurred for HTLF's new strategic plan, HTLF 3.0 during 2023.

Partnership Investment in Tax Credit Projects

Partnership investment in tax credit projects totaled $5.4 million, $5.0 million and $6.3 million for the years ended December 31, 2023, 2022 and 2021, respectively. The expense depends upon the number of tax credit projects placed in service during the year.

EFFICIENCY RATIO

One of the primary goals of HTLF 3.0 strategic initiatives is to improve its efficiency ratio, on a fully tax-equivalent basis (non-GAAP), with the goal to reach 52% over the next three years and maintain it below that level thereafter. The efficiency ratio was 79.58% (59.06% on an adjusted fully tax-equivalent basis, non-GAAP) for 2023, 61.03% (57.74% on an adjusted fully tax-equivalent basis, non-GAAP) for 2022, and 62.63% (59.48% on an adjusted fully tax-equivalent basis, non-GAAP) for 2021.

HTLF continues to pursue strategies to improve operational efficiency and its efficiency ratio, on a fully tax-equivalent basis (non-GAAP) which include the following initiatives:

Consolidation of its 11 Bank Charters

Charter consolidation was designed to eliminate redundancies and improve operating efficiency and capacity to support ongoing product and service enhancements as well as current and future growth. During the fourth quarter of 2023, HTLF successfully completed the consolidation of all 11 charters. Consolidation restructuring costs were originally projected to total $19-20 million, and at completion, the total consolidation restructuring costs were $16.9 million. Largely as a result of charter consolidation, full-time equivalent employees decreased 279 of 12%, from 2,249 full-time equivalent employees prior to the announcement of charter consolidation at December 31, 2021, to 1,970 full-time equivalent employees at December 31, 2023.

HTLF 3.0

HTLF's new strategic plan, HTLF 3.0, was announced and initiated in the fourth quarter of 2023. Initiatives of HTLF 3.0 include investing in growth through banker expansion and talent acquisition, expanding treasury management products and capabilities, enhancement of consumer and small business digital platforms, improving our efficiency ratio and footprint and facilities optimization.

Branch Optimization Strategy

During 2023, HTLF's branch network was reduced by 2 locations. During 2022, HTLF reduced its branch footprint by 11 locations. HTLF will continue to optimize its branch network and physical facilities as part of the HTLF 3.0 initiatives, which will likely result in write-downs of fixed assets and additional restructuring costs in future periods.

See "Financial Highlights" in this section above for a description of the calculation of the efficiency ratio on a fully tax-equivalent basis, which is a non-GAAP financial measure.

INCOME TAXES

HTLF's effective tax rate was 17.4% for 2023 compared to 20.8% for 2022 and 20.1% for 2021. The following items impacted HTLF's 2023, 2022 and 2021 tax calculations:

•Various tax credits of $7.0 million, $6.6 million, and $7.7 million.

•Tax expense of $4.9 million, $987,000, and $229,000 resulting from disallowed interest expense related to tax-exempt loans and securities, aligning with increases in total interest expense.

•Tax-exempt interest income as a percentage of pre-tax income of 33.3%, 11.8% and 9.9%.

•The tax-equivalent adjustment for this tax-exempt interest income was $8.6 million, $8.4 million and $7.2 million.

•Tax benefits of $0, $165,000 and $491,000 related to the release of valuation allowances on deferred tax assets.

FINANCIAL CONDITION

HTLF's total assets were $19.41 billion at December 31, 2023, a decrease of $832.5 million or 4% compared to December 31, 2022. HTLF's total assets were $20.24 billion at December 31, 2022, an increase of $969.7 million or 5% compared to $19.27 billion at December 31, 2021.

LENDING ACTIVITIES

HTLF's board of directors establishes the Bank's credit risk appetite, which is further supported by the implementation of sound lending policies, processes, and procedures designed to maintain and uphold an acceptable level of credit risk. Management and the HTLF board of directors are provided reports at least quarterly related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans.

HTLF originates commercial and industrial loans and owner occupied commercial real estate loans for a wide variety of business purposes, including lines of credit for working capital and operational purposes and term loans for the acquisition of equipment and real estate. Although most loans are made on a secured basis, loans may be made on an unsecured basis if warranted by the overall financial condition of the borrower. Terms of commercial business loans generally range from one to five years. Commercial loans are primarily made based on the identified cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The risks in the commercial and industrial portfolio include the unpredictability of the cash flow of the borrowers and the variability in the value of the collateral securing the loans. Owner occupied commercial real estate loans depend upon the cash flow of the borrowers and the collateral value of the real estate.

In 2021 and 2020, HTLF originated Paycheck Protection Plan ("PPP") loans in conjunction with the CARES Act. The PPP loans are 100% SBA guaranteed and carry a zero risk rating for regulatory capital purposes. The principal balance of PPP loans has been significantly reduced as borrowers may be eligible to have the entire principal balance forgiven and paid by the SBA.

Non-owner occupied commercial real estate loans provide financing for various non-owner occupied or income producing properties. Real estate construction loans are generally short-term or interim loans that provide financing for acquiring or developing commercial income properties, multi-family projects or single-family residential homes. The collateral required for most of these loans is based upon the discounted market value of the collateral. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover the operating expenses and debt service. Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project. Additionally, real estate construction loans have a greater risk of default in a weaker economy because repayment relies on the successful and timely completion of the project. Personal guarantees are required a majority of instances as a tertiary form of repayment. In addition, when underwriting loans for commercial real estate, careful consideration is given to the property's operating history, future operating projections, current and projected occupancy, location and physical condition.

Agricultural and agricultural real estate loans, many of which are secured by crops, machinery and real estate, are provided to finance capital improvements and farm operations as well as acquisitions of livestock and machinery. Agricultural and agricultural real estate loans present unique credit risks relating to adverse weather conditions, loss of livestock due to disease or other reasons, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural and agricultural real estate loans depends upon the profitable operation or management of the agricultural entity. Loans secured by farm equipment, livestock or crops may not provide an adequate source of repayment because of damage or depreciation. In underwriting agricultural and agricultural real estate loans, lending personnel work closely with their customers to review budgets and cash flow projections for crop production for the ensuing year. These budgets and cash flow projections are monitored closely during the year and reviewed with the customers at least annually. Lending personnel work closely with governmental agencies, including the U.S. Small Business Administration and U.S. Department of Agriculture's Rural Development Business and Industry Program Farm Service Agency, to help agricultural customers obtain credit enhancement products, such as loan guarantees, longer-term funding or interest assistance, to reduce risk.

Lenders at each Bank division are complemented by HTLF Specialized Industries, a centralized team of highly experienced middle-market lenders focused on specific industries and more complex loan structures. The team includes specialized expertise in commercial real estate, healthcare, food and agribusiness industries, and franchise finance, as well as in capital markets activities such as swaps and syndications.

Residential real estate loans are originated for the purchase or refinancing of single-family residential properties. Residential real estate loans depend upon the borrower's ability to repay the loan and the underlying collateral value. HTLF Bank provides residential mortgage loans to their customers that are retained and serviced by HTLF Bank.

Consumer lending includes motor vehicle, home improvement, home equity and small personal credit lines. Consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than one-to-four-family residential mortgage loans. Consumer loan collections are dependent on the borrower's continuing financial stability and are therefore more likely to be affected by adverse personal circumstances. Risk is reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition, and personal cash flows. A security interest, with title insurance, when necessary, is taken in the underlying real estate.

At December 31, 2023, $276.6 million or 56% of the consumer loan portfolio was in home equity lines of credit ("HELOCs") compared to $265.8 million or 52% at December 31, 2022. Under our policy guidelines for the underwriting of these lines of credit, the customer may generally receive advances of up to 80% of the value of the property.

HTLF Bank has not been active in the origination of subprime loans. Consistent with our community-focused banking model, which includes meeting the legitimate credit needs within the communities served, HTLF Bank may make loans to borrowers possessing subprime characteristics only if there are mitigating factors present that reduce the potential default risk of the loan.

HTLF’s major source of income is interest on loans. The table below presents the composition of HTLF’s loan portfolio at the end of the years indicated, in thousands:

Although repayment risk exists on all loans, different factors influence repayment risk for each type of loan. The primary risks associated with commercial, commercial real estate and agricultural loans are the quality of the borrower’s management and the health of national and regional economies. Repayment of commercial real estate, real estate construction and agricultural real estate loans may also be influenced by fluctuating property values and concentrations of loans in a specific type of real estate. Repayment on loans to individuals, including those secured by residential real estate, depends on the borrower’s continuing financial stability as well as the value of the collateral underlying the loan, and thus are more likely to be affected by adverse personal circumstances and deteriorating economic conditions. These risks are described in more detail in Item 1A. "Risk Factors" of this Annual Report on Form 10-K. We monitor loan concentrations and do not believe we have excessive concentrations in any specific industry.

We regularly monitor and continue to develop systems to oversee the quality of our loan portfolio. Under our internal loan review program, loan review officers are responsible for reviewing existing loans, validating loan ratings assigned by loan officers, identifying potential problem loans and monitoring the adequacy of the allowance for credit losses at HTLF Bank. An integral part of our loan review program is validating the effectiveness of the loan rating system, under which a rating is assigned to each loan within the portfolio based on the borrower’s financial position, repayment ability, collateral position and repayment history.

ALLOWANCE FOR CREDIT LOSSES

The process utilized by HTLF to determine the appropriateness of the allowance for credit losses is considered a critical accounting practice for HTLF. The allowance for credit losses represents management's estimate of lifetime losses in the existing loan portfolio. For additional details on the specific factors considered in determining the allowance for credit losses, refer to the critical accounting estimates section of this Annual Report on Form 10-K and Note One, "Basis of Presentation," of the consolidated financial statements included in this Annual Report on Form 10-K.

Qualitative Allowance/Economic Forecast

The qualitative allowance of HTLF's total allowance decreased $8.2 million or 18% to $37.0 million at December 31, 2023, compared to $45.3 million at December 31, 2022. Management's assessment of the non-economic risk factors in the qualitative calculation reflected the healthy, current credit environment.

HTLF has access to various third-party economic forecast scenarios provided by Moody's, which are updated quarterly in HTLF's methodology. HTLF continued to use a one year reasonable and supportable forecast period. At December 31, 2023, Moody's December 11, 2023 baseline forecast scenario was utilized, and management also considered other downturn forecast scenarios in addition to the baseline forecast to support the macroeconomic outlook used in the allowance for credit losses calculation.

The qualitative allowance of HTLF's total allowance increased $8.4 million or 23% to $45.3 million at December 31, 2022, compared to $36.9 million at December 31, 2021. Management's assessment for December 31, 2022 reflected a baseline scenario of qualitative adjustment and considered other downturn forecast scenarios, which had anticipated a moderate recession developing within the next twelve months.

CREDIT QUALITY AND NONPERFORMING ASSETS

HTLF's internal rating system for the credit quality of its loans is a series of grades reflecting management's risk assessment, based on its analysis of the borrower's financial condition. The "pass" category consists of all loans that are not in the "nonpass" category and categorized into a range of loan grades that reflect increasing, though still acceptable, risk. Movement of risk through the various grade levels in the pass category is monitored for early identification of credit deterioration. For more information on this internal rating system, see Note Four, "Loans" of HTLF’s consolidated financial statements in this Annual Report on Form 10-K.

HTLF's nonpass loans totaled $676.3 million or 6% of total loans as of December 31, 2023, compared to $533.3 million or 5% of total loans as of December 31, 2022. As of December 31, 2023, HTLF's nonpass loans consisted of approximately 62% watch loans and 38% substandard loans. The percent of nonpass loans on nonaccrual status as of December 31, 2023 was 14%.

As of December 31, 2022, HTLF's nonpass loans were comprised of approximately 48% watch loans and 52% substandard loans. The percent of nonpass loans on nonaccrual status as of December 31, 2022, was 11%.

Nonperforming loans were $97.9 million or 0.81% of total loans at December 31, 2023, compared to $58.5 million or 0.51% of total loans at December 31, 2022.

Approximately 80%, or $78.0 million, of HTLF's nonperforming loans at December 31, 2023, had individual loan balances exceeding $1.0 million, the largest of which was one relationship with a total principal balance of $40.4 million. At December 31, 2022, approximately 67%, or $39.0 million, of HTLF's nonperforming loans had individual loan balances exceeding $1.0 million, the largest of which was $6.8 million. The portion of HTLF's nonresidential real estate nonperforming loans covered by government guarantees was $10.3 million at December 31, 2023, compared to $12.5 million at December 31, 2022.

Other real estate owned

Other real estate owned was $12.5 million at December 31, 2023, compared to $8.4 million at December 31, 2022. Liquidation strategies have been identified for all the assets held in other real estate owned. Management continues to market these properties through a systematic liquidation process instead of an immediate liquidation process in order to avoid discounts greater than the projected carrying costs. Proceeds from the sale of other real estate owned totaled $6.0 million in 2023 compared to $2.6 million in 2022. Subsequent to December 31, 2023, in late January 2024, HTLF sold its largest OREO property, decreasing other real estate owned by $10 million, with no associated loss.

Financial difficulty modifications

Any loans that are modified are reviewed by HTLF to identify if a financial difficulty modification has occurred, which is when HTLF modifies a loan related to a borrower experiencing financial difficulties. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. The modification of the terms of such loans includes one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date, a permanent reduction of the recorded investment of the loan, or an other-than-insignificant payment delay. The adoption of ASU 2022-02 on January 1, 2023 eliminated the recognition and measurement of troubled debt restructured loans ("TDRs") and enhanced disclosures for modifications to loans related to borrowers experiencing financial difficulties. See Note Four to the consolidated financial statements for additional detail regarding the adoption of ASU 2022-02.

SECURITIES

The composition of HTLF's securities portfolio is managed to ensure liquidity needs are met while maximizing the return on the portfolio within the established risk appetite parameters. Securities represented 29% of HTLF's total assets at December 31, 2023, compared to 35% at December 31, 2022. Whenever possible, management intends to use a portion of the proceeds from maturities, paydowns, and sales of securities beyond those needed to fund loan growth to repay borrowings and wholesale funding. Total securities carried at fair value as of December 31, 2023, were $4.65 billion, a decrease of $1.50 billion or 24% since December 31, 2022. Total securities carried at fair value as of December 31, 2022, were $6.15 billion, a decrease of $1.38 billion or 18% since December 31, 2021.

During the fourth quarter of 2023, HTLF sold securities with proceeds totaling $865.4 million resulting in a pre-tax loss of $140.0 million to strategically reposition the balance sheet. The proceeds of the sale were used to repay high-cost wholesale deposits and short-term borrowings.

During the third quarter of 2022, HTLF transferred taxable municipal bonds with an amortized cost basis of $934.5 million and fair value of $748.3 million from available for sale to held to maturity. On the date of the transfer, accumulated other comprehensive income (loss) included $186.3 million of net unrealized losses, after tax, attributable to these securities, and the net unrealized losses will be amortized into interest income over the remaining life of the transferred securities. The bonds were transferred at fair value at the date of transfer. HTLF has the ability and intent to hold these securities to maturity.

The unrealized losses on HTLF's debt securities are the result of changes in market interest rates or widening of market spreads subsequent to the initial purchase of the securities and not related to concerns regarding the underlying credit of the issuers or the underlying collateral. For this reason and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the year ended December 31, 2023. See Note Three, "Securities" of the consolidated financial statements for further discussion regarding unrealized losses on our securities portfolio.

DEPOSITS

Total deposits were $16.20 billion as of December 31, 2023, compared to $17.51 billion as of December 31, 2022, a decrease of $1.31 billion or 7%. Excluding wholesale and institutional deposits, customer deposits were $14.85 billion as of December 31, 2023, compared to $15.22 billion as of December 31, 2022, a decrease of $367.3 million or 2%. As of December 31, 2023, 61% of HTLF's deposits were insured or collateralized.

Increases in interest rates in 2023 and 2022 encouraged customers to move deposit balances from noninterest-bearing accounts to interest bearing accounts.

HTLF maintains a granular and diverse deposit base. As of December 31, 2023, no Bank Market represented more than 14% of total customers deposits, and no major industry represented more than 10% of total commercial customer deposits.

HTLF has established policies with respect to the use of brokered deposits to limit the amount of brokered deposits as a percentage of total deposits and the HTLF Asset/Liability Committee monitors the use of brokered deposits on a regular basis, including interest rates and the total volume of such deposits in relation to total deposits. As of December 31, 2023, the level of brokered deposits falls well within the internal policy limit of 20% of total assets. HTLF has established risk limits for the level of uninsured deposits to total deposits and uninsured and collateralized deposits to total deposits as well as deposit concentration limits for the largest one, five and 100 customers, and has been in compliance with those internal requirements for the periods presented.

Other borrowings	58,622		6,814		760
Total	$	622,255	$	376,117	65	%

Borrowings generally include securities sold under agreements to repurchase, FHLB advances, swap margin payable, and discount window borrowings from the Federal Reserve Bank. These funding alternatives are utilized in varying degrees depending on their pricing and availability. HTLF Bank owns stock in the FHLB of Topeka, enabling HTLF Bank to borrow funds for short- or long-term purposes under a variety of programs. As of December 31, 2023, the amount of borrowings was $622.3 million compared to $376.1 million for the year ended 2022, an increase of $246.1 million.

HTLF Bank provides retail repurchase agreements to its customers as a cash management tool, which sweep excess funds from demand deposit accounts into these agreements. This source of funding does not increase HTLF Bank's reserve requirements. Although the aggregate balance of these retail repurchase agreements is subject to variation, the account relationships represented by these balances are primarily local. The balances of retail repurchase agreements were $42.4 million at December 31, 2023, compared to $95.3 million at December 31, 2022, a decrease of $52.9 million or 55%.

HTLF renewed its revolving credit line agreement with an unaffiliated bank on June 14, 2022. This revolving credit line agreement, which has $100.0 million of borrowing capacity, is included in borrowings, and the primary purpose of this credit line agreement is to provide liquidity to HTLF. HTLF had no advances on this line during 2023 or 2022, and no balance was outstanding on this line at December 31, 2023, and December 31, 2022. The credit agreement contains specific financial covenants which HTLF complied with as of December 31, 2023 with the exception of the return on average assets covenant for which HTLF obtained a waiver through February 22, 2024.

The net proceeds of the 2021 subordinated notes totaled $147.6 million and were used for general corporate purposes. The 2021 subordinated notes have a fixed interest rate of 2.75% until September 15, 2026, at which time the interest rate will be reset quarterly to a benchmark interest rate, which is expected to be three-month term Secure Overnight Financing Rate ("SOFR") plus a spread of 210 basis points. The 2021 subordinated notes mature on September 15, 2031, and become redeemable at HTLF's option on September 15, 2026.

In 2014, HTLF issued $75.0 million of subordinated notes with a maturity date of December 30, 2024. The notes were issued at par with an underwriting discount of $1.1 million. The interest rate on the notes is fixed at 5.75% per annum payable semi-annually. The notes were sold to qualified institutional buyers, and the proceeds were used for general corporate purposes.

For regulatory purposes, $148.2 million of total subordinated notes qualified as Tier 2 capital as of December 31, 2023.

CAPITAL RESOURCES

The Federal Reserve has adopted capital adequacy guidelines that are used to assess the adequacy of capital in supervising a bank holding company. Under Basel III, HTLF must hold a conservation buffer above the adequately capitalized risk-based capital ratios; however, the transition provision related to the conservation buffer have been extended indefinitely.

The most recent notification from the FDIC categorized HTLF and HTLF Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the categorization of any of these entities.

HTLF's capital ratios are calculated in accordance with Federal Reserve Board instructions and are required regulatory financial measures. The following table illustrates HTLF's capital ratios and the Federal Reserve's current capital adequacy guidelines for the dates indicated, in thousands. The table also indicates the fully-phased in capital conservation buffer, but the requirements to comply have been extended indefinitely.

At December 31, 2023, retained earnings that could be available for the payment of dividends to meet the most restrictive minimum capital requirements totaled $743.3 million. Retained earnings that could be available for the payment of dividends to HTLF from HTLF Bank totaled approximately $436.9 million at December 31, 2023, under the capital requirements to remain well capitalized. These dividends are the principal source of funds to pay dividends on HTLF's common and preferred stock and to pay interest and principal on its debt.

As of December 31, 2023, management believes regulatory capital ratio buffers would withstand any changes in regulatory rules that require the inclusion of unrealized losses in the total investment portfolio and remain well capitalized.

On June 26, 2020, HTLF issued and sold 4.6 million depositary shares, each representing a 1/400th interest in a share of 7.00% Fixed-Rate Reset Non-Cumulative Perpetual Preferred Stock, Series E. The depositary shares are listed on The Nasdaq Global Select Market under the symbol "HTLFP." If declared, dividends are paid quarterly in arrears at a rate of 7.00% per annum beginning on October 15, 2020. For the dividend period beginning on the first reset date of July 15, 2025, and for dividend periods beginning every fifth anniversary thereafter, each a reset date, the rate per annum will be reset based on a recent five-year treasury rate plus 6.675%. The earliest redemption date for the preferred shares is July 15, 2025. Dividends payable on common shares are subject to quarterly dividends payable on these outstanding preferred shares at the applicable dividend rate.

On August 8, 2022, HTLF filed a universal shelf registration statement with the SEC to register debt or equity securities. This shelf registration statement, which was effective immediately, provided HTLF with the ability to raise capital, subject to market conditions and SEC rules and limitations, if HTLF's board of directors decided to do so. This registration statement permits HTLF, from time to time, in one or more public offerings, to offer debt securities, subordinated notes, common stock, preferred stock, rights or any combination of these securities. The amount of securities that may have been offered was not specified in the registration statement, and the terms of any future offerings would be established at the time of the offering. The registration statement expires on August 8, 2025.

Common stockholders' equity was $1.82 billion at December 31, 2023, compared to $1.62 billion for the year ended 2022. Book value per common share was $42.69 at December 31, 2023, compared to $38.25 for the year ended 2022. Changes in common stockholders' equity and book value per common share are the result of earnings, dividends paid, stock transactions and mark-to-market adjustments for unrealized gains and losses on securities available for sale. HTLF's unrealized losses on securities available for sale including the unrealized gain on the fair value of security hedges, net of applicable taxes, reflected unrealized losses of $453.7 million and $619.2 million at December 31, 2023, and December 31, 2022, respectively.

We also enter into financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit, and are described in Note Fourteen, "Commitments," to the consolidated financial statements for additional information on these commitments. As of December 31, 2023, and December 31, 2022, commitments to extend credit aggregated $4.62 billion and $4.73 billion, and standby letters of credit aggregated $56.4 million and $55.1 million, respectively.

At December 31, 2023, and December 31, 2022, HTLF Bank had $917.0 million and $682.9 million, respectively, of standby letters of credit with the respective FHLB to secure public funds and municipal deposits.

We continue to explore opportunities to expand the size of our banking footprint by opportunistically augmenting organic growth by focusing on acquisition targets that complement or supplement our current banking strategy. This includes transactions that increase penetration in existing geographic Bank Markets, as well as acquisitions of fee income businesses that complement and build on our existing businesses or further meet the needs of our customers. Future expenditures relating to expansion efforts cannot be estimated at this time.

HTLF considers and uses derivative financial instruments as part of its interest rate risk management strategy, which may include interest rate swaps, fair value hedges, risk participation agreements, caps, floors and collars. In the first quarter of 2023, HTLF terminated cash flow hedges that were effectively converting $500.0 million of variable rate loans to fixed rate loans. In the second and third quarter of 2023, HTLF continued the strategy of using derivatives by entering into fair value hedges to manage the exposure to changes in fair value on $2.5 billion of our loan portfolio and $838.1 million of our investment portfolio. See Note Eleven, "Derivative Financial Instruments," to the consolidated financial statements for additional information on our derivative financial instruments.

Refer to "Liquidity" in Item 7 of this Annual Report on Form 10-K for further discussion regarding our cash flow and funding sources.

LIQUIDITY

Liquidity refers to our ability to maintain a cash flow that is adequate to meet maturing obligations and existing commitments, to withstand fluctuations in deposit levels, to fund operations and to provide for customers’ credit needs. The liquidity of HTLF principally depends on cash flows from operating activities, investment in and maturity of assets, changes in deposit balances, maturity of time deposits and borrowings and its ability to borrow funds in the money or capital markets.

At December 31, 2023, HTLF had $323.0 million of cash and cash equivalents, time deposits in other financial institutions of $1.2 million and securities carried at fair value of $4.65 billion. Management expects the securities portfolio to produce principal cash flows of approximately $751.4 million during 2024.

Management of investing and financing activities, and market conditions, determine the level and the stability of net interest cash flows. Management attempts to mitigate the impact of changes in market interest rates to the extent possible, so that balance sheet growth is the principal determinant of growth in net interest cash flows.

HTLF's borrowing balances depend on commercial cash management and smaller correspondent bank relationships and, as a result, will normally fluctuate. Management believes these balances to be stable sources of funds and has tested drawing on these sources. In the event of short-term liquidity needs, HTLF Bank may purchase federal funds from correspondent banks, borrow from the FHLB, and may also borrow from the Federal Reserve Bank, including utilizing the BTFP.

HTLF's current liquidity strategy includes using overnight borrowings and reducing wholesale deposits. The use of overnight borrowings provides flexibility to make repayments on demand. As of December 31, 2023, pledged securities totaled $2.63 billion. As of December 31, 2023, approximately $2.83 billion of securities remained available to pledge. Additionally, FHLB advances are collateralized with pledges of one- to four-family residential mortgages, commercial and agricultural mortgages and securities totaling $2.07 billion at December 31, 2023.

The following table shows the source of funding, balance outstanding and available borrowing capacity as of December 31, 2023, dollars in thousands:

	As of December 31, 2023
Source	Outstanding		Available
Federal Reserve Discount Window	$	—	$	1,378,898
Bank Term Funding Program	—		545,519
Federal Home Loan Bank	521,186		629,861

HTLF is focused on loan growth and strives to fund the loan growth with the least expensive source of deposits, sales of securities, or borrowings. The securities portfolio is expected to produce principal cash flows of approximately $751.4 million over the next twelve months, which could be used to fund loan growth. Additionally, growing deposits will continue to be a focus. HTLF offers the ICS and CDARS products accessed through the Intrafi network of financial institutions, which helps to reduce the amount of pledged securities.

On a consolidated basis, HTLF maintains a large balance of securities that, when combined with cash from operations, HTLF believes are adequate to meet its funding obligations.

At the parent company level, routine funding requirements consist primarily of dividends paid to stockholders, debt service on revolving credit arrangements and trust preferred securities, repayment requirements under other debt obligations and payments for acquisitions. The parent company obtains the funding to meet these obligations from dividends paid by HTLF Bank and the issuance of debt and equity securities.

As of December 31, 2023, the parent company had cash of $288.2 million. Additionally, HTLF has a revolving credit agreement with an unaffiliated bank, which was renewed most recently on June 14, 2022. HTLF's revolving credit agreement has $100.0 million of maximum borrowing capacity, of which none was outstanding at December 31, 2023. This credit

agreement contains specific financial covenants which HTLF complied with as of December 31, 2023 with the exception of the return on average assets covenant for which HTLF obtained a waiver through February 22, 2024.

The ability of HTLF to pay dividends to its stockholders is dependent upon dividends paid by HTLF Bank. HTLF Bank is subject to statutory and regulatory restrictions on the amount it may pay in dividends. To maintain acceptable capital ratios in HTLF Bank, certain portions of its retained earnings are not available for the payment of dividends. Retained earnings that could be available for the payment of dividends to HTLF under the regulatory capital requirements to remain well-capitalized totaled approximately $436.9 million as of December 31, 2023.

HTLF has filed a universal shelf registration statement with the SEC that provides HTLF the ability to raise both debt and capital, subject to SEC rules and limitations, if HTLFs board of directors decides to do so. This registration statement expires in August 2025.

Management believes that cash on hand, cash flows from operations and cash availability under existing borrowing programs and facilities will be sufficient to meeting any recurring and additional operating cash needs in 2024.

EFFECTS OF INFLATION

Consolidated financial data included in this report has been prepared in accordance with U.S. GAAP. Presently, these principles require reporting of financial position and operating results in terms of historical dollars, except for available for sale securities, trading securities, derivative instruments, certain impaired loans and other real estate which require reporting at fair value. Changes in the relative value of money due to inflation or recession are generally not considered.

In management’s opinion, changes in interest rates affect the financial condition of a financial institution to a far greater degree than changes in the inflation rate. While interest rates are greatly influenced by changes in the inflation rate, they do not change at the same rate or in the same magnitude as the inflation rate. Rather, interest rate volatility is based on changes in the expected rate of inflation, as well as on changes in monetary and fiscal policies. HTLF seeks to insulate itself from interest rate volatility by ensuring that rate-sensitive assets and rate-sensitive liabilities respond to changes in interest rates in a similar time frame and to a similar degree. See Item 7A of this Annual Report on Form 10-K for a discussion on the process HTLF utilizes to mitigate market risk.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of loss arising from adverse changes in market prices and rates, including the risk that our net income will be materially impacted by changes in interest rates. HTLF's market risk is comprised primarily of interest rate risk resulting from HTLF Bank's core banking activities of lending and deposit gathering.

HTLF uses an interest rate management process to measure market risk and manage exposure within policy limits approved by the HTLF Board of Directors. Exposure to market risk is reviewed on a regular basis by HTLF Bank’s Asset/Liability Committee as well as HTLF's and HTLF Bank's management and Board of Directors.

HTLF's balance sheet market risk profile is measured and reviewed at least quarterly. As part of the review, interest rate sensitivity analysis is performed, which simulates changes in net interest income in response to various hypothetical interest rate scenarios capturing asset and liability pricing mismatches over a one-year and two-year time horizon. Increasing net interest income in a rising rate environment would indicate that asset-related income will increase faster than liability-related expense over the simulation period.

The core interest rate risk analysis utilized by HTLF examines the balance sheet under many interest rate scenarios including shocks, ramps, yield curve twists, market-based, as well as those that may be deemed extreme or highly unlikely. We use a net interest income ("NII") simulation model to measure the estimated changes in NII that would result over various time horizons from immediate and sustained changes in interest rates. This model is an interest rate risk management tool and the results are not necessarily an indication of our future net interest income. The model has inherent limitations and these results are based on a given set of rate changes and assumptions at a point in time. Key assumptions in the analysis include balance sheet growth, product mix-shift, the repricing behavior of interest-bearing deposits (i.e., deposit betas), behavior of deposits with indeterminate maturities, prepayment assumptions on financial instruments with embedded options such as loans and investment securities, as well as cashflow reinvestment assumptions.

The base scenario assumes a static balance sheet and static interest rates as of December 31, 2023, no changes to product mix shift and cashflow reinvestment at current market interest rates. HTLF also assumes a correlation, referred to as a deposit beta,

with respect to interest-bearing deposits, as the rates paid to deposit holders change at a different pace when compared with changes in average benchmark interest rates. Generally, time deposits are assumed to have a high correlation, while other interest bearing accounts are assumed to have a lower correlation. The model assumes interest-bearing deposits reprice at 54% and total deposits reprice at 39% in an up rate scenario and that interest-bearing deposits reprice at 48% and total deposits reprice at 34% in a down rate scenario, as compared to the change in benchmark interest rates. The majority of our loans are variable rate and are assumed to reprice in accordance with their contractual terms. Some loans and investment securities include the opportunity of prepayment (embedded options) and the simulation model uses prepayment assumptions to estimate these accelerated cash flows and reinvests the proceeds at current simulated yields Changes that could vary significantly from HTLF's assumptions include loan and deposit growth or contraction, loan and deposit pricing, changes in the mix of earning assets or funding sources, and future asset/liability management decisions, all of which may have significant effects on our net interest income.

Key assumptions are monitored at least annually or as needed, as part of the sensitivity analysis and back testing framework. When appropriate and applicable assumptions are recalibrated taking into consideration among other factors, the impact of a full interest rate cycle on the balance sheet. In 2023, HTLF recalibrated certain prepayment assumptions and updated cash flow characteristics. None of the changes were material to the simulation model.

The following table presents the most recent simulation of net interest income at December 31, 2023, in thousands. The interest rate scenarios assume parallel instantaneous changes to interest rate levels by 100 and 200 basis points.

As of December 31, 2023, HTLF's through the cycle deposit beta (calculated by taking the change in company deposit rates compared to the benchmark federal funds target rate over a period of time) for customer deposits was approximately 31% for all customer deposits and 37% including both customer and wholesale and institutional deposits. As of December 31, 2023, HTLF's through the cycle beta excluding noninterest-bearing accounts was approximately 45% for customer deposits and 51% including both customer and wholesale and institutional deposits. As of December 31, 2022, HTLF's through the cycle beta for customer deposits was approximately 9% for all customer deposits and 18% including both customer and wholesale and institutional deposits. As of December 31, 2022, HTLF's through the cycle beta excluding noninterest-bearing accounts was approximately 14% for customer deposits and 27% including both customer and wholesale and institutional deposits. HTLF compares actual deposit betas to the betas utilized in the net interest margin simulation models to monitor model performance and to monitor our deposits in comparison with market competition. Management also uses deposit betas to understand the risk to net interest income in various interest rate environments.

We use derivative financial instruments to manage the impact of changes in interest rates on our future interest income or interest expense. We are exposed to credit-related losses in the event of nonperformance by the counterparties to these derivative instruments but believe we have minimized the risk of these losses by entering into the contracts with large, stable financial institutions. The estimated fair market values of these derivative instruments are presented in Note Eleven to the consolidated financial statements.

We enter into financial instruments with off balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. These

instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract relating to the commitment. Commitments generally have fixed expiration dates and may require collateral from the borrower. Standby letters of credit are conditional commitments issued by HTLF to guarantee the performance of a customer to a third-party up to a stated amount and with specified terms and conditions. These commitments to extend credit and standby letters of credit are not recorded on the balance sheet until the loan is made or the letter of credit is issued.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

ONE

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations - Heartland Financial USA, Inc. ("HTLF") is a bank holding company with locations in Iowa, Illinois, Wisconsin, New Mexico, Arizona, Colorado, Montana, Minnesota, Kansas, Missouri, Texas and California. The principal services of HTLF, which are provided through HTLF Bank, are FDIC-insured deposit accounts and related services, and loans to businesses and consumers. The loans consist primarily of commercial and industrial, owner-occupied commercial real estate, non-owner occupied commercial real estate, real estate construction, agricultural and agricultural real estate, residential real estate and consumer loans.

Principles of Presentation - The consolidated financial statements include the accounts of HTLF and its subsidiaries: HTLF Bank; DB&T Community Development Corp.; Heartland Community Development, Inc.; Heartland Financial USA, Inc. Insurance Services; Heartland Financial Statutory Trust IV; Heartland Financial Statutory Trust V; Heartland Financial Statutory Trust VI; Heartland Financial Statutory Trust VII; Morrill Statutory Trust I; Morrill Statutory Trust II; Sheboygan Statutory Trust I, CBNM Capital Trust I, Citywide Capital Trust III, Citywide Capital Trust IV, Citywide Capital Trust V, OCGI Statutory Trust III, OCGI Capital Trust IV, BVBC Capital Trust II, and BVBC Capital Trust III. All HTLF’s subsidiaries are wholly-owned as of December 31, 2023.

As of December 31, 2023, HTLF Bank and its respective bank brands listed below operated as divisions of HTLF Bank:

•Arizona Bank & Trust

•Bank of Blue Valley

•Citywide Banks

•Dubuque Bank & Trust

•First Bank & Trust

•Illinois Bank & Trust

•Minnesota Bank & Trust

•New Mexico Bank & Trust

•Premier Valley Bank

•Rocky Mountain Bank

•Wisconsin Bank & Trust

During the first quarter of 2023, HTLF reclassified swap and loan syndication income (collectively, "capital markets fees") to capital markets fees from other noninterest income on the consolidated statements of income, and all prior periods have been adjusted.

During the second quarter of 2023, HTLF reclassified Federal Deposit Insurance Corporation ("FDIC") insurance premiums to FDIC insurance assessments from professional fees on the consolidated statements of income, and all prior periods have been adjusted.

In the second quarter of 2023, HTLF amended and restated its Certificate of Incorporation and filed Certificates of Elimination with the state of Delaware with respect to Series A, B, C, and D preferred stock issuances, which returned these previously designated shares to authorized but unissued. The following shows the details of Series A, B, C and D preferred stock at December 31, 2022:

•Series A Junior Participating preferred stock-par value $1 per share; authorized 16,000 shares; none issued or outstanding at December 31, 2022

•Series B Fixed Rate Cumulative Perpetual Preferred Stock-par value $1 per share; 81,698 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

•Series C Senior Non-Cumulative Perpetual Preferred Stock-par value $1 per share; 81,698 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

•Series D Senior Non-Cumulative Perpetual Convertible Preferred Stock-par value $1 per share; 3,000 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

After the cancellation of Series A, B, C and D preferred shares, total undesignated preferred shares authorized increased to 188,500 from 6,104 at December 31, 2022, of which none were issued or outstanding at both December 31, 2023 and December 31, 2022.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and prevailing practices within the banking industry. In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheets and revenues and expenses for the years then ended. Actual results could differ significantly from those estimates. A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for credit losses.

Business Combinations - HTLF applies the acquisition method of accounting in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 805, Business Combinations. Under the acquisition method, HTLF recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at fair value as of the acquisition date, with the acquisition-related transaction costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective.

Cash and Cash Equivalents - For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits held at the Federal Reserve Bank, federal funds sold to other banks and other short-term investments. Generally, federal funds are purchased and sold for one-day periods.

Trading Securities - Trading securities represent those securities HTLF intends to actively trade and are stated at fair value with changes in fair value reflected in noninterest income. HTLF had no trading securities at both December 31, 2023 and 2022.

Available for Sale ("AFS") Debt Securities and Equity Securities - Available for sale securities consist of those securities not classified as held to maturity or trading, which management intends to hold for indefinite periods of time or that may be sold in response to changes in interest rates, prepayments or other similar factors. Available for sale securities are stated at fair value with any unrealized gain or loss, net of applicable income tax, reported as a separate component of stockholders’ equity. Security premiums and discounts are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

Realized securities gains or losses on securities sales (using a specific identification method) are included in securities gains, net in the consolidated statements of income.

Equity securities include Community Reinvestment Act funds with readily determinable fair values and are carried at fair value. Certain equity securities do not have readily determinable fair values, such as Federal Reserve Bank stock and Federal Home Loan Bank stock, which are held for debt and regulatory purposes and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. HTLF did not record any impairment or other adjustments to the carrying amount of these investments during the years ended December 31, 2023, and December 31, 2022.

Allowance for Credit Losses on AFS Debt Securities - HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, with regard to debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the

value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

The decline in fair value of an AFS debt security due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes. Although these evaluations involve judgment, an unrealized loss in the fair value of a debt security is generally considered to not be related to credit when the fair value of the security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration in the financial condition of the issuer, and HTLF does not intend to sell nor does it believe it will be required to sell the security before the recovery of its cost basis. HTLF had no allowance for credit losses on AFS debt securities recorded at December 31, 2023, and December 31, 2022.

Securities Held to Maturity - Securities which HTLF has the ability and positive intent to hold to maturity are classified as held to maturity. Such securities are stated at amortized cost, adjusted for premiums and discounts that are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

Allowance for Credit Losses on Held to Maturity Debt Securities - HTLF measures expected credit losses on held to maturity debt securities on a collective basis based on security type. The estimate of expected credit losses considers historical credit information that is adjusted for current conditions and supportable forecasts. HTLF's held to maturity debt securities consist primarily of investment grade obligations of states and political subdivisions. The forecast and forecast period used in the calculation of the allowance for credit losses for loans is used in calculating the allowance for credit losses on held to maturity debt securities. HTLF had no allowance for credit losses on held to maturity debt securities recorded at both December 31, 2023, and December 31, 2022.

Loans Held to Maturity - Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount outstanding, net of cumulative charge-offs, unamortized net deferred loan origination fees and costs and unamortized premiums or discounts on purchased loans. HTLF has a loan policy which establishes the credit risk appetite, lending standards and underwriting criteria designed so that HTLF may extend credit in a prudent and sound manner. The HTLF loan policy is reviewed and approved on a regular basis. A reporting system supplements the review process by providing management and the board with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans.

HTLF originates commercial and industrial loans and owner occupied commercial real estate loans for a wide variety of business purposes, including lines of credit for capital and operating purposes and term loans for real estate and equipment purchases. Non-owner occupied commercial real estate loans provide financing for various non-owner occupied or income producing properties. Real estate construction loans are generally short-term or interim loans that provide financing for acquiring or developing commercial income properties, multi-family projects or single-family residential homes. Agricultural and agricultural real estate loans provide financing for capital improvements and farm operations, as well as livestock and machinery purchases. Residential real estate loans are originated for the purchase or refinancing of single-family residential properties. Consumer loans include loans for motor vehicles, home improvement, home equity and personal lines of credit.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. HTLF’s policy is to discontinue the accrual of interest income on any loan when, in the opinion of management, there is a reasonable doubt as to the timely collection of the interest and principal, normally when a loan is 90 days past due. When interest accruals are deemed uncollectible, interest credited to income in the current year is reversed and interest accrued in prior years is charged to the allowance for credit losses. A loan can be restored to accrual status if the borrower has resumed paying the full amount of the scheduled contractual interest and principal payments on the loan, and (1) all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period of time, and (2) there is a sustained period of repayment performance (generally a minimum of six months) by the borrower in accordance with the scheduled contractual terms.

Allowance for Credit Losses for Loans - The allowance for credit losses is a valuation account that is deducted from the loans held to maturity amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged-off against the allowance when management believes the loan balance is deemed to be uncollectible. Provisions for credit losses for loans and recoveries on loans previously charged-off by HTLF are added back to the allowance.

HTLF's allowance model is designed to consider the current contractual term of the loan, defined as starting as of the most recent renewal date and ending at maturity date.

Management's estimation of expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts, including expected defaults and prepayments. Historical loss experience is generally the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms and differences in economic conditions, both current conditions and reasonable and supportable forecasts. If HTLF is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it is required to estimate expected credit losses for the remaining life using an approach that reverts to historical credit loss information. The components of the allowance for credit losses are described more specifically below.

Quantitative Factors

The quantitative component of the allowance for credit losses is measured using historical loss experience using a look back period, currently over the most recent 16 years, on a pool basis for loans with similar risk characteristics. HTLF utilizes third-party software to calculate the expected credit losses using two separate methodologies. For certain commercial and agricultural loans, the expected credit losses are calculated through a transition matrix model derived probability of default and loss given default methodology. The transition matrix model determines the life of loan probability of default using the historical transitions of loans between risk ratings and through default. The probability of default and loss given default methodology has been developed using HTLF’s historical loss experience over the look back period. For smaller commercial and agricultural loans, residential real estate loans and consumer loans, a lifetime average historical loss rate is established for each pool of loans based upon an average loss rate calculated using HTLF historical loss experience over the look back period.

The risks in the commercial and industrial loan portfolio include the unpredictability of the cash flow of the borrowers and the variability in the value of the collateral securing the loans. Owner occupied commercial real estate loans depend upon the cash flow of the borrowers and the collateral value of the real estate. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover the operating expenses and debt service. Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project. Additionally, real estate construction loans have a greater risk of default in a weaker economy because the source of repayment relies on the successful and timely completion of the project. Agricultural and agricultural real estate loans depend upon the profitable operation or management of the farm property securing the loan. Loans secured by farm equipment, livestock or crops may not provide an adequate source of repayment because of damage or depreciation. Residential real estate loans depend upon the borrower's ability to repay the loan and the underlying collateral value. Consumer loans depend upon the borrower's personal financial circumstances and continued financial stability.

If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and on nonaccrual status are individually assessed using a collateral dependency calculation. A loan is collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. The impairment will be recognized by creating a specific reserve against the loan with a corresponding charge to provision expense. In most cases, the specific reserve will be charged off in the same quarter the loss is probable. In some cases, when HTLF believes certain loans do not share the same risk characteristics with other loans in the pool, the standard allows for these loans to be individually assessed. All individually assessed loan calculations are completed at least semi-annually.

Qualitative Factors

HTLF's allowance methodology also has a qualitative component, the purpose of which is to provide management with a means to take into consideration changes in current conditions that could potentially have an effect on the level of recognized loan losses, that otherwise fail to show up in the quantitative analysis performed in determining its base loan loss rates.

HTLF utilizes the following qualitative factors:

•changes in lending policies and procedures

•changes in the nature of loans

•experience and ability of management

•changes in the credit quality of the loan portfolio

•risk in acquired portfolios

•concentrations of credit

The qualitative factors for changes in lending policies and procedures, management and acquired portfolios are weighted as one factor. The other qualitative factors noted above are equally weighted as individual factors.

The qualitative adjustments are based on the comparison of the current condition to the average condition over the look back period. The adjustment amount can be either positive or negative depending on whether the current condition is better or worse than the historical average. HTLF incorporates the adjustments for changes in current conditions using an overlay approach. The adjustments are applied as a percentage adjustment in addition to the calculated historical loss rates of each pool. These adjustments reflect the extent to which HTLF expects current conditions to differ from the conditions that existed for the period over which historical information was evaluated. HTLF utilizes an anchoring approach to determine the minimum and maximum amount of qualitative allowance for credit losses, which is determined by comparing the highest and lowest historical rate to the current quantitative allowance rate to calculate the rate for the adjustment.

Economic Forecasting

The allowance for credit losses estimate incorporates a reasonable and supportable forecast of various macro-economic indices over the remaining life of HTLF’s assets. HTLF utilizes an overlay approach for its economic forecasting component, similar to the method utilized for the qualitative factors. The length of the reasonable and supportable forecast period is a judgmental determination based on the level to which the entity can support its forecast of economic conditions that drive its estimate of expected loss. HTLF compares forecasted macro-economic indices, such as unemployment and gross domestic product, to the economic conditions that existed over HTLF's look back period.

HTLF uses Moody's baseline economic forecast scenario, which is updated quarterly in HTLF's methodology, and considers other Moody's forecast scenarios to support the economic forecast component of the allowance for credit losses. The economic forecast reverts to the historical mean immediately at the end of the reasonable and supportable forecast period. HTLF utilized a one-year reasonable and supportable forecast period for the calculation of the December 31, 2023, and December 31, 2022, allowance for credit losses.

It is expected that actual economic conditions will, in many cases, differ from forecasts because the ultimate outcomes during the forecast period may be affected by events that were unforeseen, such as economic disruption and fiscal or monetary policy actions, which are exacerbated by longer forecasting periods. This uncertainty would be relevant to the entity’s confidence level as to the outcomes being forecasted. That is, an entity is likely less confident in the ultimate outcome of events that will occur at the end of the forecast period as compared to the beginning. As a result, actual future economic conditions may not be an effective indicator of the quality of management’s forecasting process, including the length of the forecast period.

Financial Difficulty Modifications - Any loans that are modified are reviewed by HTLF to identify if a financial difficulty modification has occurred, which is when HTLF modifies a loan related to a borrower experiencing financial difficulties. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. The modification of the terms of such loans includes one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date, a permanent reduction of the recorded investment of the loan, or an other-than-insignificant payment delay. The adoption of ASU 2022-02 on January 1, 2023 eliminated the recognition and measurement of TDRs and enhanced disclosures for modifications to loans related to borrowers experiencing financial difficulties. See Note Four to the consolidated financial statements for additional detail regarding the adoption of ASU 2022-02.

Loans Held for Sale - Loans held for sale are stated at the lower of cost or fair value on an aggregate basis. Gains or losses on sales are recorded in noninterest income. Direct loan origination costs and fees are deferred at origination of the loan. These deferred costs and fees are recognized in noninterest income as part of the gain or loss on sales of loans upon sale of the loan.

At December 31, 2023 and 2022, loans held for sale primarily consisted of 1-4 family residential mortgages.

Allowance for Credit Losses on Unfunded Loan Commitments - HTLF estimates expected credit losses over the contractual term of the loan for the unfunded portion of the loan commitment that is not unconditionally cancellable by HTLF using the same collective allowance methodology for credit losses for loans described above. Management uses an estimated average utilization rate to determine the exposure at default. The allowance for unfunded commitments is recorded in the Accrued Expenses and Other Liabilities section of the consolidated balance sheets.

Mortgage Servicing and Transfers of Financial Assets - Prior to dissolving its mortgage operations in 2023, HTLF regularly sold residential mortgage loans to others, primarily government sponsored entities, on a non-recourse basis. Sold loans are not included in the accompanying consolidated balance sheets. HTLF generally retained the right to service the sold loans for a fee prior to the sale of its mortgage servicing rights portfolio in the first quarter of 2023. First Bank & Trust, a division of HTLF Bank, serviced mortgage loans primarily for government sponsored entities with aggregate unpaid principal balance of $0 and $725.9 million, at December 31, 2023 and 2022, respectively.

Premises, Furniture and Equipment, net - Premises, furniture and equipment are stated at cost less accumulated depreciation. The provision for depreciation of premises, furniture and equipment is determined by straight-line and accelerated methods over the estimated useful lives of 18 to 39 years for buildings, 15 years for land improvements and 3 to 7 years for furniture and equipment.

Premises, Furniture and Equipment Held for Sale - Premises, furniture and equipment are stated at the estimated fair value less disposal costs. Subsequent write-downs and gains or losses on the sales are recorded to gain (loss) on sales/valuation of assets, net.

Other Real Estate - Other real estate represents property acquired through foreclosures and settlements of loans. Property acquired is recorded at the estimated fair value of the property less disposal costs. The excess of carrying value over fair value less disposal costs is charged against the allowance for credit losses. Subsequent write downs estimated on the basis of later valuations and gains or losses on sales are charged to gain (loss) on sales/valuation of assets, net. Expenses incurred in maintaining such properties are charged to other real estate and loan collection expenses.

Goodwill - Goodwill represents the excess of the purchase price of acquired subsidiaries’ net assets over their fair value at the purchase date. HTLF assesses goodwill for impairment annually, and more frequently if events occur which may indicate possible impairment, and assesses goodwill at the reporting unit level, also giving consideration to overall enterprise value as part of that assessment.

In evaluating goodwill for impairment, HTLF first assesses qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If HTLF concludes that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then no further testing of goodwill assigned to the reporting unit is required. However, if HTLF concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then HTLF performs a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to recognize, if any. In addition, the income tax effects of tax-deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. A goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.

Core Deposit Intangibles and Customer Relationship Intangibles, Net - Core deposit intangibles are amortized over 8 to 18 years on an accelerated basis. Customer relationship intangibles were amortized over 22 years on an accelerated basis. Annually, HTLF reviews these intangible assets for events or circumstances that may indicate a change in the recoverability of the underlying basis.

Servicing Rights, Net - Mortgage and commercial servicing rights associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and recorded on the consolidated statements of income as a component of gains on sale of loans held for sale. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned.

First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing portfolio in the first quarter of 2023, and the value of the mortgage servicing rights was derecognized on the consolidated balance sheet. In prior periods, the carrying values of these rights were reviewed quarterly for impairment based on the calculation of their fair value as performed by an outside third-party. For purposes of measuring impairment, the rights were stratified into certain risk characteristics including loan type and loan term. At December 31, 2022, no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 15 years, and no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 30 years.

Cash Surrender Value on Life Insurance - HTLF and its subsidiaries have purchased life insurance policies on the lives of certain officers. The one-time premiums paid for the policies, which coincide with the initial cash surrender value, are recorded as an asset. Increases or decreases in the cash surrender value, other than proceeds from death benefits, are recorded as noninterest income in income on bank owned life insurance. Proceeds from death benefits first reduce the cash surrender value attributable to the individual policy and then any additional proceeds are recorded in other noninterest income.

Income Taxes - HTLF and its subsidiaries file a consolidated federal income tax return and separate or combined income or franchise tax returns as required by the various states. HTLF recognizes certain income and expenses in different time periods for financial reporting and income tax purposes. The provision for deferred income taxes is based on an asset and liability

approach and represents the change in deferred income tax accounts during the year, including the effect of enacted tax rate changes. A valuation allowance is provided to reduce deferred tax assets if their expected realization is deemed not to be more likely than not.

A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. HTLF recognizes interest and penalties related to income tax matters in income tax expense.

Derivative Financial Instruments - HTLF uses derivative financial instruments as part of its interest rate risk management, which includes interest rate swaps, certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. FASB ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC 815, HTLF records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives used to manage the exposure to changes in the fair value of a recognized asset or liability on the consolidated balance sheets are fair value hedges. To qualify for hedge accounting, HTLF must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship. Hedge ineffectiveness, if any, is measured periodically throughout the life of the hedging relationship.

For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in the fair value of the derivative, if any, is recognized immediately in other noninterest income. HTLF assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instrument with the cumulative changes in cash flows of the designated hedged item or transaction. No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness. In the first quarter of 2023 HTLF terminated its cash flow hedges. It was determined that the forecasted transactions remain probable, so the unrealized gains at termination were kept in accumulated comprehensive income and are being amortized into income over the remaining life of the forecasted transaction.

HTLF had multiple fair value hedging relationships at December 31, 2023. HTLF uses hedge accounting in accordance with ASC 815. For hedges where the fair value change in the loan portfolio is being hedged, unrealized gains and losses representing the change in fair value of the derivative and the change in fair value of the risk being hedged on the related loan are being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. For hedges where the fair value change in the investment portfolio are being hedged, the change in the fair value of the derivative and the change in the fair value of the risk being hedged on the related investments is being recorded in interest income on the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

HTLF also has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income.

HTLF does not use derivatives for speculative purposes. Derivatives not designated as hedges are not speculative and are used to manage HTLF’s exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements of ASC 815.

Mortgage Derivatives - HTLF uses interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities. These commitments are considered derivative instruments. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. As of December 31, 2023, HTLF was winding out of this activity due to dissolving its mortgage operations.

Fair Value Measurements - Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using discounted cash flow or other valuation techniques. Inputs into the valuation methods are subjective in nature, involve uncertainties, and require judgment and therefore cannot be determined with precision. Accordingly, the derived fair value estimates presented herein are not necessarily indicative of the amounts HTLF could realize in a current market exchange. Assets and liabilities are categorized into three levels based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine the fair value. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. HTLF's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Below is a brief description of each fair value level:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Segment Reporting - Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), which is the Chief Executive Officer of HTLF, in deciding how to allocate resources and assess the financial and operating performance of HTLF. HTLF’s operating segments provide, and primarily derive revenue, through full service commercial and consumer banking. HTLF has determined that the economic characteristics, operating models, performance metrics, suite of products and services, customer base, and regulatory requirements are similar for its operating segments and has therefore aggregated them into one reportable segment.

Treasury Stock - Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price. When treasury stock is reissued, any difference between the sales proceeds, or fair value when issued for business combinations, and the cost is recognized as a charge or credit to capital surplus. HTLF had no treasury stock at December 31, 2023 and December 31, 2022.

Trust Department Assets - Property held for customers in fiduciary or agency capacities is not included in the accompanying consolidated balance sheets because such items are not assets of HTLF Bank.

Earnings Per Share - Basic earnings per share is determined using net income available to common stockholders and weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average common shares and assumed incremental common shares issued. Amounts used in the determination of basic and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021, are shown in the table below, dollars and number of shares in thousands, except per share data:

	2023		2022		2021

Subsequent Events - HTLF has evaluated subsequent events that may require recognition or disclosure through the filing date of this Annual Report on Form 10-K with the SEC.

Subsequent to December 31, 2023, in February of 2024, HTLF announced that HTLF Bank had signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024.

Effect of New Financial Accounting Standards

ASU 2022-01

In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method," which expands the current last-of-layer method by allowing multiple hedged layers to be designated for a single closed portfolio of financial assets or one or more beneficial interests secured by a portfolio of financial instruments. HTLF adopted this ASU on January 1, 2023, and these amendments were applied prospectively.

ASU 2022-02

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." These amendments eliminate the troubled debt restructurings ("TDR") recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, these amendments require that an entity disclose current-period gross charge-offs by year of origination for loans receivable within the scope of Subtopic 326-20. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These amendments should be applied prospectively. If an entity elects to early adopt ASU 2022-02 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. An entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. HTLF adopted this ASU on January 1, 2023, as required, and the adoption did not have a material impact on its results of operations, financial position or liquidity.

ASU 2023-02

In March 2023, the FASB issued ASU 2023-02 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Task Force)." ASU 2023-02 expands the permitted use of the proportional amortization method, which is currently only available to low-income housing tax credit investments, to other tax equity investments if certain conditions are met. Under the proportional

amortization method, the initial cost of an investment is amortized in proportion to the income tax benefits received and both the amortization of the investment and the income tax benefits received are recognized as a component of income tax expense. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and must be applied on either a modified retrospective or a retrospective basis. The adoption of this amendment is not expected to have a material impact on the results of operations or financial position.

ASU 2023-06

In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." The amendments in this Update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to, or technical corrections of, the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The amendments in this ASU are not expected to have a material impact on the results of operations or financial position.

TWO

CASH AND DUE FROM BANKS

HTLF Bank is required to maintain certain average cash reserve balances as a non-member bank of the Federal Reserve System. On March 15, 2020, the Federal Reserve temporarily suspended the reserve requirement due to the COVID-19 pandemic, and as a result, there was no reserve requirement at both December 31, 2023, and December 31, 2022.

During the third quarter of 2022, HTLF transferred taxable municipal bonds with an amortized cost basis of $934.5 million and fair value of $748.3 million from available for sale to held to maturity. On the date of the transfer, accumulated other comprehensive income (loss) included $186.3 million of net unrealized losses, after tax, attributable to these securities, and the net unrealized losses will be amortized into interest income over the remaining life of the transferred securities. The bonds were transferred at fair value at the date of transfer.

As of December 31, 2023, HTLF had $28.0 million compared to $33.0 million at December 31, 2022, of accrued interest receivable, which is included in other assets on the consolidated balance sheets. HTLF does not consider accrued interest receivable in the carrying amount of financial assets held at amortized cost basis or in the allowance for credit losses calculation.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

The unrealized losses on HTLF's mortgage and asset-backed securities are the result of changes in market interest rates or widening of market spreads after the initial purchase of the securities. The losses are not related to concerns regarding the underlying credit of the issuers or the underlying collateral. It is expected that the securities will not be settled at a price less than the amortized cost of the investment. Because the decline in fair value is attributable to changes in interest rates or widening market spreads and not credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the years ended December 31, 2023 and December 31, 2022.

The unrealized losses on HTLF's obligations of states and political subdivisions are the result of changes in market interest rates or widening of market spreads after the initial purchase of the securities. Management monitors the published credit ratings of these securities and the stability of the underlying municipalities. Because the decline in fair value is attributable to changes in interest rates or widening market spreads due to insurance company downgrades and not underlying credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the years ended December 31, 2023 and December 31, 2022.

In the first quarter of 2022, HTLF sold two obligations of states and political subdivisions securities from the held to maturity portfolio. Because the evaluation of the underlying credit quality of the individual securities indicated significant deterioration, it was unlikely HTLF would recover the remaining basis of the securities prior to maturity and therefore inconsistent with HTLF's original intent upon purchase and classification of these held to maturity securities. The carrying value of these securities was $2.2 million, and the associated gross gains were $100,000.

The following table summarizes, in thousands, the carrying amount of HTLF's held to maturity debt securities by investment rating as of December 31, 2023 and December 31, 2022, which are updated quarterly and used to monitor the credit quality of the securities:

	December 31, 2023		December 31, 2022
Rating
AAA	$	88,550	$	79,598
AA, AA+, AA-	583,816		588,354
A+, A, A-	139,658		136,624
BBB	20,133		20,623
Not Rated	6,084		4,204
Total	$	838,241	$	829,403

Included in other securities were shares of stock in each Federal Home Loan Bank (the "FHLB") of Des Moines, Dallas and Topeka at an amortized cost of $25.8 million at December 31, 2023 and $12.3 million at December 31, 2022.

HTLF Bank is required to maintain FHLB stock as a member of the FHLB. These equity securities are "restricted" in that they can only be sold back to the respective institutions or another member institution at par. Therefore, they are less liquid than other marketable equity securities and their fair value approximates amortized cost. HTLF considers its FHLB stock as a long-term investment that provides access to competitive products and liquidity. HTLF evaluates impairment in these investments based on the ultimate recoverability of the par value and at December 31, 2023, did not consider the investments to be other than temporarily impaired.

As of December 31, 2023, HTLF had $65.4 million compared to $49.1 million as of December 31, 2022, of accrued interest receivable, which is included in other assets on the consolidated balance sheets. HTLF does not consider accrued interest receivable in the allowance for credit losses calculation.

The following table shows the balance in the allowance for credit losses at December 31, 2023, and December 31, 2022, and the related loan balances, disaggregated on the basis of measurement methodology, in thousands. If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and are on nonaccrual are individually assessed using a collateral dependency calculation. All other loans are collectively evaluated for losses.

HTLF's internal rating system is a series of grades reflecting management's risk assessment, based on its analysis of the borrower's financial condition. The "pass" category consists of all loans that are not in the "nonpass" category and categorized into a range of loan grades that reflect increasing, though still acceptable risk. Movement of risk through the various grade levels in the pass category is monitored for early identification of credit deterioration.

The "nonpass" category consists of watch, substandard, doubtful and loss loans. The "watch" rating is attached to loans where the borrower exhibits negative trends in financial circumstances due to borrower specific or systemic conditions that, if left uncorrected, threaten the borrower's capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. These credits are closely monitored for improvement or deterioration.

The "substandard" rating is assigned to loans that are inadequately protected by the current net worth and repaying capacity of the borrower and that may be further at risk due to deterioration in the value of collateral pledged. Well-defined weaknesses jeopardize liquidation of the debt. These loans are still considered collectible; however, a distinct possibility exists that HTLF will sustain some loss if deficiencies are not corrected. Substandard loans may exhibit some or all the following weaknesses: deteriorating financial trends, lack of earnings, inadequate debt service capacity, excessive debt and/or lack of liquidity.

The "doubtful" rating is assigned to loans where identified weaknesses in the borrowers' ability to repay the loan make collection or liquidation in full, based on existing facts, conditions and values, highly questionable and improbable. These borrowers are usually in default, lack liquidity and capital, as well as resources necessary to remain as an operating entity. Specific pending events, such as capital injections, liquidations or perfection of liens on additional collateral, may strengthen the credit, thus deferring the rating of the loan as "loss" until the exact status of the loan can be determined. The loss rating is assigned to loans considered uncollectible. As of December 31, 2023, and December 31, 2022, HTLF had no loans classified as doubtful and no loans classified as loss.

On December 17, 2014, HTLF issued $75.0 million of subordinated notes with a maturity date of December 30, 2024. The notes were issued at par with an underwriting discount of $1.1 million. The interest rate on the notes is fixed at 5.75% per annum, payable semi-annually. In connection with the sale of the notes, the balance of deferred issuance costs included in term debt was $38,000 at December 31, 2023, and $76,000 at December 31, 2022. These deferred costs are amortized on a straight-line basis over the life of the notes.

For regulatory purposes, $148.2 million of the total $223.0 million of subordinated notes qualified as Tier 2 capital as of December 31, 2023.

DERIVATIVE FINANCIAL INSTRUMENTS

HTLF considers and uses derivative financial instruments as part of its interest rate risk management strategy, which may include interest rate swaps, fair value hedges, risk participation agreements, caps, floors, collars, and certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. HTLF's current strategy includes the use of interest rate swaps. In addition, HTLF facilitates back-to-back loan swaps to assist customers in managing their interest rate risk while executing offsetting interest rate swaps with dealer counterparties.

HTLF's objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amounts to be exchanged between the counterparties. HTLF is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. HTLF minimizes this risk by entering into derivative contracts with counterparties that meet HTLF’s credit standards, and the contracts contain collateral provisions protecting the at-risk party. HTLF has not experienced any losses from nonperformance by these counterparties. HTLF monitors counterparty risk in accordance with the provisions of ASC 815. HTLF was required to post $27.7 million of collateral at December 31, 2023, compared to $793,000 as of December 31, 2022, related to derivative financial instruments. HTLF's counterparties were required to pledge $44.8 million at December 31, 2023, compared to $45.1 million at December 31, 2022. HTLF records interest rate derivatives subject to master netting agreements at their gross value and does not offset derivative assets and liabilities on the consolidated balance sheets.

HTLF's derivative and hedging instruments are recorded at fair value on the consolidated balance sheets. See Note Eighteen, "Fair Value," for additional fair value information and disclosures.

Cash Flow Hedges

In 2021, two interest rate swap transactions were terminated, and the debt was converted to variable rate subordinated debentures. For the next twelve months, HTLF estimates cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense related to the terminated swaps will total $227,000.

In the first quarter of 2023, HTLF terminated its interest rate swap agreement, which effectively converted $500.0 million of variable rate loans to fixed rate loans. For the next twelve months, HTLF estimates cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense will total $985,000.

HTLF had no derivative instruments designated as cash flow hedges at December 31, 2023. The table below identifies the balance sheet category and fair value of HTLF's derivative instrument designated as a cash flow hedge at December 31, 2022, in thousands:

	Notional Amount	Fair Value	Balance Sheet Category

For the Year Ended December 31, 2022
Interest rate swap	$	13	Interest income	$	487

Fair Value Hedges

HTLF uses interest rate swaps to convert certain long term fixed rate loans to floating rates to hedge interest rate risk exposure. HTLF also uses interest rate swaps to mitigate the risk of changes in the fair market value of certain municipal and mortgage-backed securities. The changes in the fair values of derivatives that have been designated and qualify for fair value hedge accounting are recorded in the same line item in the consolidated statements of income as the changes in the fair value of the hedged items attributable to the risk being hedged.

HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in the fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

During 2023, HTLF entered into interest rate swaps designated as fair value hedges with initial notional amounts totaling $838.1 million primarily designed to provide protection for unrealized securities losses against the impact of higher mid-to-long term interest rates. HTLF also executed interest rate swaps designated as a fair value hedges with total original notional amounts of $2.5 billion to convert certain long-term fixed rate loans to floating rates to hedge interest rate risk exposure using the portfolio layer method, which allows HTLF to designate as the hedged item a stated amount of the assets that are not expected to be affected by prepayments, defaults and other factors that would affect the timing and amount of cash flow.

The table below identifies the fair value of the interest rate swaps designated as fair value hedges and the balance sheet category of the interest rate swaps at December 31, 2023, and December 31, 2022, in thousands:

Embedded Derivatives

HTLF has fixed rate loans with embedded derivatives. The loans contain terms that affect the cash flows or value of the loan similar to a derivative instrument, and therefore are considered to contain an embedded derivative. The embedded derivatives are bifurcated from the loans because the terms of the derivative instrument are not clearly and closely related to the loans. The embedded derivatives are recorded at fair value on the consolidated balance sheets as a part of other assets, and changes in the fair value are a component of noninterest income. The table below identifies the notional amount, fair value and balance sheet category of HTLF's embedded derivatives as of December 31, 2023, and December 31, 2022, in thousands:

	Notional Amount		Fair Value		Balance Sheet Category

Back-to-Back Loan Swaps

HTLF has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps, HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free-standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income, and for the years ended December 31, 2023, and December 31, 2022, no gains or losses were recognized. HTLF recognized $7.7 million in fee income for the year ended December 31, 2023, compared to $6.6 million for the year ended December 31, 2022.

The table below identifies the balance sheet category and fair values of HTLF's derivative instruments designated as loan swaps at December 31, 2023 and 2022, in thousands:

Other Free-Standing Derivatives

HTLF has entered into interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities that are considered derivative instruments. HTLF enters into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on the commitments to fund the loans as well as on residential mortgage loans available for sale. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. HTLF was required to pledge $0 at both December 31, 2023, and December 31, 2022, as collateral for these forward commitments. HTLF's counterparties were required to pledge no cash as collateral at both December 31, 2023, and December 31, 2022, as collateral for these forward commitments.

HTLF acquired undesignated interest rate swaps in 2015. These swaps were entered into primarily for the benefit of customers seeking to manage their interest rate risk and are not designated against specific assets or liabilities on the consolidated balance sheet or forecasted transactions and therefore do not qualify for hedge accounting in accordance with ASC 815. These swaps are carried at fair value on the consolidated balance sheets as a component of other liabilities, with changes in the fair value recorded as a component of other noninterest income.

The table below identifies the balance sheet category and fair values of HTLF's other free standing derivative instruments not designated as hedging instruments at December 31, 2023, and December 31, 2022, in thousands:

Forward commitments	6,400		47		Other Assets
Forward commitments	5,750		(99)		Other Liabilities

HTLF recognizes gains and losses on other free-standing derivatives in two separate income statement categories. Interest rate lock commitments and forward commitments are recognized in net gains on sale of loans held for sale and undesignated interest rate swaps are recognized in other noninterest income. The table below identifies the gains and losses recognized in income on HTLF's other free standing derivative instruments not designated as hedging instruments for the years ended December 31, 2023, and December 31, 2022, in thousands:

INCOME TAXES

The current income tax provision reflects the tax consequences of revenue and expenses currently taxable or deductible on various income tax returns for the year reported. The deferred income tax provision generally reflects the net change in deferred income tax assets and liabilities during the year, excluding any deferred income tax assets and liabilities of acquired businesses. The components of the provision for income taxes for the years ended December 31, 2023, 2022, and 2021 were as follows, in thousands:

	2023		2022		2021
Current:
Federal	$	18,844	$	45,911	$	32,440

Total income tax expense	$	16,857	$	55,573	$	55,335

Temporary differences between the amounts reported in the financial statements and the tax basis of assets and liabilities result in deferred taxes. Deferred tax assets and liabilities at December 31, 2023 and 2022, were as follows, in thousands:

	2023		2022

As a result of acquisitions, HTLF had net operating loss carryforwards for federal income tax purposes of approximately $14.0 million at December 31, 2023, and $17.2 million at December 31, 2022. The associated deferred tax asset was $2.9 million at December 31, 2023, and $3.6 million at December 31, 2022. These net carryforwards expire during the period from December 31, 2025, through December 31, 2035, and are subject to an annual limitation of approximately $3.1 million. Net operating loss carryforwards for state income tax purposes were approximately $191.9 million at December 31, 2023, and $203.4 million at December 31, 2022. The associated deferred tax asset, net of federal tax, was $9.9 million at December 31, 2023, and $16.3 million at December 31, 2022. These carryforwards have begun to expire and will continue to do so until December 31, 2031.

A valuation allowance against the deferred tax asset due to the uncertainty surrounding the utilization of these state net operating loss carryforwards was $9.4 million at December 31, 2023, and $15.5 million at December 31, 2022. During both 2023 and 2022, HTLF had book write-downs on investments that, for tax purposes, would generate capital losses upon disposal. Due to the uncertainty of HTLF's ability to utilize the potential capital losses, a valuation allowance for these potential losses totaled $1.7 million at December 31, 2023, and $1.5 million at December 31, 2022. HTLF released valuation allowances of $0 and $165,000 in 2023 and 2022, respectively, on deferred tax assets for capital losses it expects to realize on the disposal of partnership investments.

Realization of the deferred tax asset over time is dependent upon the existence of taxable income in carryback periods or the ability to generate sufficient taxable income in future periods. In determining that realization of the deferred tax asset was more likely than not, HTLF considered a number of factors, including its taxable income during carryback periods, its recent earnings history, its expectations for earnings in the future and, where applicable, the expiration dates associated with its tax carryforwards.

The actual income tax expense from continuing operations differs from the expected amounts for the years ended December 31, 2023, 2022, and 2021, (computed by applying the U.S. federal corporate tax rate of 21% for 2023, 2022, and 2021 income before income taxes) are as follows, in thousands:

HTLF's income taxes included solar energy tax credits totaling $4.2 million, $4.2 million, and $6.1 million during 2023, 2022 and 2021, respectively. Federal historic rehabilitation tax credits included in HTLF's income taxes totaled $1.1 million, $1.0 million, and $720,000 in 2023, 2022, and 2021, respectively. Additionally, investments in certain low-income housing partnerships totaled $9.3 million at December 31, 2023, $10.4 million at December 31, 2022, and $5.1 million at December 31, 2021. These investments generated federal low-income housing tax credits of $1.2 million during 2023, $1.1 million at December 31, 2022, and $538,000 at December 31, 2021. These investments are expected to generate federal low-income housing tax credits of approximately $1.0 million for 2024, $790,000 for 2025, $740,000 for 2026 and $705,000 for 2027. Additionally, HTLF had new markets tax credits of $360,000 and $300,000 in 2023 and 2022, respectively.

On December 31, 2023, the amount of unrecognized tax benefits was $709,000, including $129,000 of accrued interest and penalties. On December 31, 2022, the amount of unrecognized tax benefits was $719,000, including $91,000 of accrued interest and penalties. If recognized, the entire amount of the unrecognized tax benefits would affect the effective tax rate.

The tax years ended December 31, 2020, and later remain subject to examination by the Internal Revenue Service. For state purposes, the tax years ended December 31, 2018, and later remain open for examination. HTLF does not anticipate any significant increase or decrease in unrecognized tax benefits during the next twelve months.

EMPLOYEE BENEFIT PLANS

HTLF sponsors a defined contribution retirement plan covering substantially all employees. The plan includes matching contributions and non-elective contributions. Matching contributions and non-elective contributions are limited to a maximum amount of the participant's wages as defined by federal law.

HTLF's subsidiaries made matching contributions of up to 5% of participants' wages in 2023 and 3% of participants' wages in 2022 and 2021. Costs charged to operating expenses with respect to the matching contributions were $7.9 million, $5.3 million, and $5.1 million for 2023, 2022 and 2021, respectively.

Non-elective contributions to this plan are subject to approval by the HTLF Board of Directors. The HTLF subsidiaries fund and record as an expense all approved contributions. Costs of these contributions, charged to operating expenses, were $3.1 million, $5.8 million, and $5.1 million for 2023, 2022 and 2021, respectively.

In addition, HTLF has a non-qualified defined contribution plan that allows eligible employees to make voluntary contributions into a deferred compensation plan. Any non-elective contributions to this plan are subject to approval by the HTLF Board of Directors. For the years ended December 31, 2023, 2022 and 2021, the employer contributions to the non-qualified defined contribution plan were $235,000, $222,500 and $237,200, respectively, and are included in the matching contributions and non-elective contributions amounts noted above.

FOURTEEN

COMMITMENTS AND CONTINGENT LIABILITIES

HTLF utilizes a variety of financial instruments in the normal course of business to meet the financial needs of customers and to manage its exposure to fluctuations in interest rates. These financial instruments include lending related and other commitments as indicated below as well as derivative instruments shown in Note Eleven, "Derivative Financial Instruments." HTLF Bank makes various commitments and incurs certain contingent liabilities that are not presented in the accompanying consolidated financial statements. The commitments and contingent liabilities include various guarantees, commitments to extend credit and standby letters of credit.

Commitments to extend credit are agreements to lend to a customer if there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. HTLF Bank evaluates the creditworthiness of customers to which they extend a credit commitment on a case-by-case basis and may require collateral to secure any credit extended. The amount of collateral obtained is based upon management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties. Standby letters of credit and financial guarantees are conditional commitments issued by HTLF Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. At December 31, 2023, and at December 31, 2022, commitments to extend credit aggregated $4.62 billion and $4.73 billion, respectively, and standby letters of credit aggregated $56.4 million and $55.1 million, respectively.

Previously, HTLF entered into commitments to sell mortgage loans to reduce interest rate risk on certain mortgage loans held for sale and loan commitments, which were recorded in the consolidated balance sheets at their fair values. HTLF does not anticipate any material loss as a result of the commitments and contingent liabilities. Residential mortgage loans sold to others were predominantly conventional residential first lien mortgages originated under HTLF's usual underwriting procedures and were most often sold on a nonrecourse basis. HTLF's agreements to sell residential mortgage loans in the normal course of business, primarily to GSE's, which usually required certain representations and warranties on the underlying loans sold, related to credit information, loan documentation, collateral, and insurability, which if subsequently are untrue or breached, could require HTLF to repurchase certain loans affected. HTLF had no repurchase obligation at both December 31, 2023 and December 31, 2022. HTLF had no new requests for repurchases during 2023 and 2022.

There are certain legal proceedings pending against HTLF and its subsidiaries at December 31, 2023, that are ordinary routine litigation incidental to business. While the ultimate outcome of current legal proceedings cannot be predicted with certainty, it is the opinion of management that the resolution of these legal actions should not have a material effect on HTLF's consolidated financial position or results of operation.

STOCK-BASED COMPENSATION

HTLF may grant, through its Compensation and Human Capital Committee (the "Compensation Committee") non-qualified and incentive stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units and cash incentive awards, under its 2020 Long-Term Incentive Plan (the "Plan") which authorized 1,460,000 of common stock available for issuance. At December 31, 2023, 744,310 shares of common stock were reserved for future issuance under awards that may be granted under the Plan to employees and directors of, and service providers to, HTLF or its subsidiaries.

ASC Topic 718, "Compensation-Stock Compensation" requires the measurement of the cost of employee services received in exchange for an award of equity instruments based upon the fair value of the award on the grant date. The cost of the award is based upon its fair value estimated on the date of grant and recognized in the consolidated statements of income over the vesting period of the award. The fair market value of restricted stock and restricted stock units is based on the fair value of the underlying shares of common stock on the date of grant. Forfeitures are accounted for as they occur.

HTLF's income tax expense included $123,000 of expense and $131,000 of benefit for the years ended December 31, 2023, and December 31, 2022, respectively, related to the vesting and forfeiture of equity-based awards.

Restricted Stock Units

The Plan permits the Compensation Committee to grant restricted stock units ("RSUs"). The time-based RSUs represent the right, without payment, to receive shares of HTLF common stock at a specified date in the future. Generally, the time-based RSUs vest over three years in equal installments in March of each of the three years following the year of the grant.

The Compensation Committee has granted three-year performance-based RSUs. These performance-based RSUs will be earned based upon satisfaction of performance targets for the three-year performance period, which is defined in the RSU agreement. These performance-based RSUs or a portion thereof may vest after measurement of performance in relation to the performance targets.

The time-based RSUs may also vest upon death or disability, upon a change in control or upon a "qualified retirement" (as defined in the RSU agreement), and the three-year performance-based RSUs vest to the extent that they are earned upon death or disability or upon a "qualified retirement" (as defined in the RSU agreement) after measurement of performance.

All of HTLF's RSUs will be settled in common stock upon vesting. Most RSUs granted after March 2023 accrue dividends, which are paid without interest only upon vesting. Dividend equivalents with respect to RSUs forfeited are also forfeited. RSUs granted prior to 2023 are not entitled to dividend equivalents.

A summary of the status of RSUs as of December 31, 2023, 2022 and 2021, and changes during the years ended December 31, 2023, 2022, and 2021, follows:

Total compensation costs recorded for RSUs were $9.0 million, $7.8 million and $8.5 million, for 2023, 2022 and 2021, respectively. As of December 31, 2023, there were $8.8 million of total unrecognized compensation costs related to the Plan for RSUs which are expected to be recognized through 2026.

Stock Options

The plan provides the Compensation Committee the authority to grant stock options. During the year ended December 31, 2023, 0 options were granted. There were 64,518 options granted in the year ended December 31, 2022, and no options granted in the year ended December 31, 2021. Options granted generally vest over the first four years in equal installments on the anniversary date of the grant. The exercise price of the stock options granted is established by the Compensation Committee, but the exercise price may not be less than the fair market value of the shares on the date the options are granted.

The stock options may also vest upon death or disability, upon a change in control or upon a "qualified retirement" as defined in the stock option agreement.

A summary of the status of the stock options as of December 31, 2023, 2022, and 2021, and changes during the years ended December 31, 2023, 2022, and 2021 follows:

As of December 31, 2023, there was $490,000 of total unrecognized compensation costs related to the Plan for options that are expected to be recognized through 2026.

Employee Stock Purchase Plan

HTLF maintains an employee stock purchase plan (the "ESPP"), which was adopted in May 2016 and replaced the 2006 ESPP, that permits all eligible employees to purchase shares of HTLF common stock at a discounted price as determined by the Compensation Committee. Under ASC Topic 718, compensation expense related to the ESPP of $192,000 was recorded in 2023, $214,000 was recorded in 2022, and $228,000 was recorded in 2021.

A maximum of 500,000 shares is available for purchase under the ESPP, and as of December 31, 2023, 171,537 shares remain available for purchase. Beginning with the 2020 plan year, the Compensation Committee authorized HTLF to make ESPP purchases semi-annually, and the purchases are to be made as soon as practicable on or after June 30 and December 31. For employee deferrals made in the 2023 plan year, shares purchased in 2023 totaled 60,583. For employee deferrals made in the 2022 plan year, shares purchased in 2022 totaled 49,169. For employee deferrals made in the 2021 plan year, shares purchased in 2021 totaled 46,899.

REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS ON SUBSIDIARY DIVIDENDS

HTLF Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that,

if undertaken, could have a direct material effect on HTLF Bank's financial statements. The regulations prescribe specific capital adequacy guidelines that involve quantitative measures of a bank’s assets, liabilities and certain off balance sheet items as calculated under regulatory accounting practices. Capital classification is also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require HTLF Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined).

The requirements to be categorized as well-capitalized under the Tier 1 leverage capital ratio is 4% for all banks. The minimum requirement to be well-capitalized for the Tier 1 risk-based capital ratio is 8%. The total risk-based capital ratio minimum requirement to be well-capitalized remained is 10%. Management believes, as of December 31, 2023 and 2022, that HTLF Bank met all capital adequacy requirements to which it was subject.

As of December 31, 2023 and 2022, the FDIC categorized HTLF Bank, and all HTLF member banks prior to charter consolidation, as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Banks must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 common equity and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since December 31, 2023, that management believes have changed each institution’s category.

HTLF Bank's, and all HTLF member banks prior to charter consolidation, actual capital amounts and ratios are also presented in the tables below, in thousands:

The ability of HTLF to pay dividends to its stockholders is dependent upon dividends paid by its subsidiaries. HTLF Bank is subject to certain statutory and regulatory restrictions on the amount it may pay in dividends. To maintain acceptable capital ratios for the HTLF Bank, certain portions of their retained earnings are not available for the payment of dividends. Retained earnings that could be available for the payment of dividends to HTLF totaled approximately $743.3 million as of December 31, 2023, under the most restrictive minimum capital requirements. Retained earnings that could be available for the payment of dividends to HTLF totaled approximately $436.9 million as of December 31, 2023, under the capital requirements to remain well capitalized.

EIGHTEEN

FAIR VALUE

HTLF utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities carried at fair value, which include available for sale, trading securities and equity securities with a readily determinable fair value, and derivatives are recorded in the consolidated balance sheets at fair value on a recurring basis. Additionally, from time to time, HTLF may be required to record at fair value other assets on a nonrecurring basis such as loans held for sale, loans held to maturity and certain other assets including, but not limited to, mortgage servicing rights and other real estate owned. These nonrecurring fair value adjustments typically involve application of lower of cost or fair value accounting or write-downs of individual assets.

Fair Value Hierarchy

Under ASC 820, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring or non-recurring basis.

Assets

Securities Available for Sale and Held to Maturity

Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are generally recorded at cost. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities. Level 2 securities include U.S. government and agency securities, mortgage and asset-backed securities and private collateralized mortgage obligations, municipal bonds, equity securities and corporate debt securities. On a quarterly basis, a secondary independent pricing service is used for the securities portfolio to validate the pricing from HTLF's primary pricing service.

Equity Securities with a Readily Determinable Fair Value

Equity securities with a readily determinable fair value generally include Community Reinvestment Act mutual funds and are classified as Level 2 due to the infrequent trading of these securities. The fair value is based on the price per share.

Loans Held for Sale

Loans held for sale are carried at the lower of cost or fair value on an aggregate basis. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, HTLF classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2.

Loans Held to Maturity

HTLF does not record loans held to maturity at fair value on a recurring basis. However, from time to time, certain loans are considered collateral dependent and an allowance for credit losses is established. The fair value of individually assessed loans is measured using the fair value of the collateral. In accordance with ASC 820, individually assessed loans measured at fair value are classified as nonrecurring Level 3 in the fair value hierarchy.

Premises, Furniture and Equipment Held for Sale

HTLF values premises, furniture and equipment held for sale based on third-party appraisals less estimated disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in

selling bank premises, furniture and equipment, in determining the fair value of particular properties. Accordingly, the valuation of premises, furniture and equipment held for sale is subject to significant external and internal judgment. HTLF periodically reviews premises, furniture and equipment held for sale to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. Premises, furniture and equipment held for sale are measured at fair value and are classified as nonrecurring Level 3 in the fair value hierarchy.

Mortgage Servicing Rights

Mortgage servicing rights assets represent the value associated with servicing residential real estate loans that have been sold to outside investors with servicing retained. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds and delinquency rate assumptions as inputs. All these assumptions require a significant degree of management estimation and judgment. Mortgage servicing rights are subject to impairment testing. The carrying values of these rights are reviewed quarterly for impairment based upon the calculation of fair value as performed by an outside third-party. For purposes of measuring impairment, the rights are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance. HTLF classifies mortgage servicing rights as nonrecurring with Level 3 measurement inputs.

On March 31, 2023, HTLF sold its mortgage servicing rights portfolio. The transaction qualified as a sale, and $7.7 million of mortgage servicing rights were derecognized on the consolidated balance sheet as of March 31, 2023. The book value and fair value were both $0 as of March 31, 2023.

Derivative Financial Instruments

HTLF's current interest rate risk strategy includes cash flow hedges and interest rate swaps. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. To comply with the provisions of ASC 820, HTLF incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, HTLF has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although HTLF has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2023, and December 31, 2022, HTLF has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, HTLF has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

Interest Rate Lock Commitments

HTLF uses an internal valuation model that relies on internally developed inputs to estimate the fair value of its interest rate lock commitments which is based on unobservable inputs that reflect management's assumptions and specific information about each borrower. Interest rate lock commitments are classified in Level 3 of the fair value hierarchy.

Forward Commitments

The fair value of forward commitments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments in active markets that HTLF has the ability to access and are classified in Level 2 of the fair value hierarchy.

Other Real Estate Owned

Other real estate owned ("OREO") represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the fair value of the property at the time of acquisition (representing the property's cost basis), plus any acquisition costs, or the estimated fair value of the property, less disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in selling OREO, in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. HTLF periodically reviews OREO to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. OREO is classified as nonrecurring Level 3 of the fair value hierarchy.

The tables below present HTLF's assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2023, and December 31, 2022, in thousands, aggregated by the level in the fair value hierarchy within which those measurements fall:

(1) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(2) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.

(1) The significant unobservable input used in the fair value measurement is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio calculation takes into consideration historical data and loan-level data.
(2) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(3) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.
(4) The significant unobservable inputs used in the discounted cash flow analysis are the discount rate and constant prepayment rate.

The changes in fair value of the interest rate lock commitments, which are Level 3 financial instruments and are measured on a recurring basis, are summarized in the following table, in thousands:

	For the Years Ended
	December 31, 2023		December 31, 2022
Balance at January 1,	$	174	$	1,306
Total gains (losses), net, included in earnings	(290)		(1,828)
Issuances	1,864		3,683
Settlements	(1,748)		(2,987)
Balance at period end	$	—	$	174

Gains included in net gains on sale of loans held for sale attributable to interest rate lock commitments held at December 31, 2023, and December 31, 2022, were $0 and $174,000, respectively.

The table below is a summary of the estimated fair value of HTLF's financial instruments (as defined by ASC 825) as of December 31, 2023, and December 31, 2022, in thousands. The carrying amounts in the following table are recorded in the consolidated balance sheets under the indicated captions. In accordance with ASC 825, the assets and liabilities that are not financial instruments are not included in the disclosure, including the value of the commercial and mortgage servicing rights, premises, furniture and equipment, premises, furniture and equipment held for sale, OREO, goodwill, other intangibles and other liabilities.

HTLF does not believe that the estimated information presented below is representative of the earnings power or value of HTLF. The following analysis, which is inherently limited in depicting fair value, also does not consider any value associated with either existing customer relationships or the ability of HTLF to create value through loan origination, obtaining deposits or fee generating activities. Many of the estimates presented below are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.

Cash and Cash Equivalents — The carrying amount is a reasonable estimate of fair value due to the short-term nature of these instruments.

Time Deposits in Other Financial Institutions — The carrying amount is a reasonable estimate of the fair value due to the short-term nature of these instruments.

Securities — For equity securities with a readily determinable fair value and debt securities either held to maturity, available for

sale or trading, fair value equals quoted market price if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. For Level 3 securities, HTLF utilizes independent pricing provided by third-party vendors or brokers.

Other Investments — Fair value measurement of other investments, which consists primarily of FHLB stock, are based on their redeemable value, which is at cost. The market for these securities is restricted to the issuer of the stock and subject to impairment evaluation.

Loans — The fair value of loans were determined using an exit price methodology. The exit price estimation of fair value is based on the present value of the expected cash flows. The projected cash flows are based on the contractual terms of the loans, adjusted for prepayments and a discount rate based on the relative risk of the cash flows. Other considerations include the loan type, the remaining life of the loan and credit risk.

The fair value of individually assessed or impaired loans is measured using the fair value of the underlying collateral. The fair value of loans held for sale is estimated using quoted market prices or sales contracts.

Cash surrender value on life insurance — Life insurance policies are held on certain officers. The carrying value of these policies approximates fair value as it is based on the cash surrender value adjusted for other charges or amounts due that are probable at settlement. As such, HTLF classifies the estimated fair value of the cash surrender value on life insurance as Level 2.

Derivative Financial Instruments — The fair value of all derivatives is estimated based on the amount that HTLF would pay or would be paid to terminate the contract or agreement, using current rates, and when appropriate, the current creditworthiness of the counterparty.

Interest Rate Lock Commitments — The fair value of interest rate lock commitments is estimated using an internal valuation model, which includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated closing ratio based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment group.

Forward Commitments — The fair value of these instruments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments.

Deposits — The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value.

Borrowings and Term Debt — Rates currently available to HTLF for debt with similar terms and remaining maturities are used to estimate fair value of existing debt.

Commitments to Extend Credit, Unused Lines of Credit and Standby Letters of Credit — Based upon management's analysis of the off balance sheet financial instruments, there are no significant unrealized gains or losses associated with these financial instruments based upon review of the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties.

NINETEEN

REVENUE

ASC 606, Revenue from Contracts with Customers, requires revenue to be recognized at an amount that reflects the consideration to which HTLF expects to be entitled in exchange for transferring goods or services to a customer. ASC 606 applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of HTLF's revenue streams including interest income, loan servicing income, net securities gain and losses, net unrealized gains and losses on equity securities, net gains on sale of loans held for sale, valuation adjustment on servicing rights, income from bank owned life insurance and other noninterest income are outside the scope of ASC 606. Revenue streams including service charges and fees, interchange fees on credit and debit cards, trust fees and brokerage and insurance commissions are within the scope of ASC 606.

Service Charges and Fees

Service charges and fees consist of revenue generated from deposit account related service charges and fees, overdraft fees, customer service fees and other service charges, credit card fee income, debit card income and other service charges and fees.

Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders and other deposit account related fees. HTLF's performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees, including overdraft fees, are largely transaction based, and therefore, the performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Customer service fees and other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. HTLF's performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.

Credit card fee income and debit card income are comprised of interchange fees, ATM fees, and merchant services income. Credit card fee income and debit card income are earned whenever HTLF Bank's debit and credit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Bank cardholder uses an ATM that is not owned by one of HTLF's Banks or a non-bank cardholder uses HTLF-owned ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees.

Trust Fees

Trust fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. HTLF's performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the average daily market value or month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days before or after month end through a direct charge to customers’ accounts. HTLF does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. HTLF's performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Brokerage and Insurance Commissions

Brokerage commission primarily consists of commissions related to broker-dealer contracts. The contracts are between the customer and the broker-dealer, and HTLF satisfies its performance obligation and earns commission when the transactions are completed. The recognition of revenue is based on a defined fee schedule and does not require significant judgment. Payment is received shortly after services are rendered. Insurance commissions are related to commissions received directly from the insurance carrier. HTLF acts as an insurance agent between the customer and the insurance carrier. HTLF's performance obligations and associated fee and commission income are defined with each insurance product with the insurance company. When insurance payments are received from customers, a portion of the payment is recognized as commission revenue.

Contract Balances

HTLF does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2023, 2022, and 2021, HTLF did not have any significant contract balances or capitalized contract acquisition costs.

LEASES

HTLF, as lessee, leases certain assets for use in its operations. Leased assets primarily include real estate property for retail branches, ATM locations and operations centers with terms extending through 2031. All HTLF's leases are classified as operating leases. HTLF excludes leases with an original term of twelve months or less and equipment leases (deemed immaterial) on the consolidated balance sheets. HTLF leases some of its facilities to third parties and receives rental income from such lease agreements which is not significant.

The table below presents HTLF's right-of-use ("ROU") assets and lease liabilities as of December 31, 2023 and December 31, 2022, in thousands:

		As of December 31,
	Classification	2023		2022
Operating lease right-of-use assets	Other assets	$	25,859	$	29,429
Operating lease liabilities	Accrued expenses and other liabilities	$	29,333	$	31,681

The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. HTLF’s lease agreements often include one or more options to renew at HTLF’s discretion. If at lease inception, HTLF considers the exercising of a renewal option to be reasonably certain, HTLF will include the extended term in the calculation of the ROU asset and lease liability. HTLF utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. The variable lease cost primarily represents variable payments such as common area maintenance and utilities.

The table below presents the lease costs and supplemental information as of December 31, 2023, 2022, and 2021, in thousands:

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Heartland Financial USA, Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Heartland Financial USA, Inc. and

subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of

income, comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 23, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our

responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the

consolidated financial statements that was communicated or required to be communicated to the audit

committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial

statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Assessment of the allowance for credit losses for loans and unfunded loan commitments collectively evaluated

As discussed in Notes 1, 4, and 5 to the consolidated financial statements, the Company’s allowance for credit losses related to loans and unfunded loan commitments collectively evaluated for credit losses is comprised of an allowance for credit losses on loans and an allowance for credit losses on unfunded loan commitments (the collective ACL). As of December 31, 2023, the total allowance for credit losses related to loans and unfunded loan commitments was $122.6 million and $16.5 million, respectively, of which $102.2 million and $16.5 million, respectively, was related to the collective ACL. The Company estimates the collective ACL using a current expected credit losses methodology which is based on relevant information about past events, current conditions, and a reasonable and supportable forecast that affect the collectability of the reported loan and commitment amounts, including expected defaults and prepayments. The allowance for credit losses on unfunded commitments leverages the same methodology utilized for the allowance for credit losses for loans. The Company estimates the collective ACL on a pool basis for loans and commitments with similar risk characteristics using 1) a transition matrix model derived probability of default (PD) and loss given default (LGD) methodology, which is based on transition of loans between risk ratings and through default based on the Company’s historical loss experience, for certain commercial and agricultural loans, or 2) a lifetime average historical loss model for all other commercial and agricultural loans, residential real estate loans, consumer loans, and commitments. A portion of the collective ACL on outstanding loans and commitments is comprised of qualitative adjustments, based on a comparison of current conditions to the average conditions over the look back period. The qualitative adjustments are determined by the Company using an anchoring approach to determine the minimum and maximum amount of qualitative allowance, which is determined by comparing the highest and lowest historical lifetime average loss rate to the current quantitative allowance rate to calculate the rate for the adjustment. The collective ACL utilizes an overlay approach for its economic forecasting component which incorporates a reasonable and supportable forecast of various macro-economic indices. The Company utilizes an economic forecast scenario which reverts to the historical mean immediately at the end of the reasonable and supportable forecast period. For the allowance for credit losses on unfunded loan commitments, the Company separately estimates the exposure at default using estimated average utilization rates.

We identified the assessment of the collective ACL as a critical audit matter. A high degree of audit effort, including specialized skills and knowledge, and subjective and complex auditor judgment was involved in the assessment of the collective ACL estimate. Specifically, the assessment encompassed the evaluation of the collective ACL methodology, including the methods and models used to estimate (1) the PD and LGD and the related assumption of the risk ratings for certain commercial and agricultural loans, (2) the lifetime average historical loss rates, and (3) the method used to estimate the economic forecasting component of the qualitative component and determination of that component, certain assumptions related to the qualitative component including the reasonable supportable forecast period, anchoring, and weighting. The assessment also included an evaluation of the conceptual soundness and performance of the PD and LGD model and lifetime average historical loss model. In addition, auditor judgment was required to evaluate the sufficiency of audit evidence obtained.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s measurement of the collective ACL estimates, including controls over the:

•development and approval of the collective ACL methodology

•continued use of the PD and LGD model and lifetime average historical loss model

•identification and determination of the assumptions used in the PD and LGD model

•identification and determination of the assumptions used in the lifetime average historical loss model

•development of the qualitative adjustments, including the method used to estimate the economic forecasting component overlay, and related assumptions including the anchoring and weighting approaches, and the reasonable and supportable forecast period

•analysis of the collective ACL results, trends and ratios.

We evaluated the Company’s process to develop the collective ACL estimate by testing certain sources of data, factors, and assumptions that the Company used, and considered the relevance and reliability of such data, factors, and assumptions. In addition, we involved credit risk professionals with specialized skills and knowledge, who assisted in evaluating:

•the Company’s collective ACL methodology for compliance with U.S. generally accepted accounting principles

•judgments made by the Company relative to the continued use of the PD and LGD model and lifetime average historical loss model, by comparing them to relevant Company-specific metrics and trends and applicable industry and regulatory practices

•the conceptual soundness of the PD and LGD model and lifetime average historical loss model by inspecting the model documentation to determine whether the models are suitable for their intended use

•the methodology used to develop the qualitative adjustments including the economic forecasting component, the assumptions used in the adjustments including reasonable and supportable forecast period, anchoring, and weighting, and the effect of those adjustments on the collective ACL estimate compared with relevant credit risk factors and consistency with credit trends and identified limitations of the underlying quantitative models

•individual risk ratings for a selection of commercial and agricultural loan relationships by evaluating the financial performance of the borrower, sources of repayment, and any relevant guarantees or underlying collateral.

We also assessed the sufficiency of the audit evidence obtained related to the collective ACL estimates by evaluating the:

•cumulative results of the audit procedures

•qualitative aspects of the Company’s accounting practices

•potential bias in the accounting estimates.

ITEM 9A. CONTROLS AND PROCEDURES

Under the direction of our Chief Executive Officer and Chief Financial Officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) promulgated under the Securities and Exchange Act of 1934, as amended) as of December 31, 2023. Based on that evaluation, our management, including the Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, in a manner that allows timely decisions regarding required disclosure.

MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible for establishing and maintaining effective internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management, board of directors and stockholders regarding the reliability of financial reporting and the preparation and fair presentation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our internal control over financial reporting based upon the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013). Based on our assessment, our internal control over financial reporting was effective as of December 31, 2023.

KPMG LLP, the independent registered public accounting firm that audited HTLF’s consolidated financial statements as of and for the year ended December 31, 2023, included herein, has issued a report on HTLF’s internal control over financial reporting. This report follows management’s report.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

To the Stockholders and Board of Directors

Heartland Financial USA, Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Heartland Financial USA, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control –Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements), and our report dated February 23, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and

dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company;

and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect

misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1 Rev 4-17-2023 HEARTLAND FINANCIAL USA, INC. 2020 LONG-TERM INCENTIVE PLAN DIRECTOR RESTRICTED STOCK UNIT AWARD AGREEMENT (LEGAL BANK BOARD MEMBERS) The Participant specified below is hereby granted a restricted stock unit award by HEARTLAND FINANCIAL USA, INC. (the “Company”), under the HEARTLAND FINANCIAL USA, INC. 2020 LONG-TERM INCENTIVE PLAN (the “Plan”). The restricted stock units awarded by this Award Agreement (this “Agreement”) shall be subject to the terms of the Plan and the terms set forth in this Agreement. All capitalized terms used in this Agreement and not otherwise defined have the meaning assigned to them in the Plan. Section 1. Award. The Company hereby grants to the Participant an award of restricted stock units (each such unit, an “RSU”), where each RSU represents the right of the Participant to receive one Share of Company common stock in the future, subject to the terms of this Agreement and the Plan. For purposes of this Agreement: The “Participant” is: %%FIRST_NAME_LAST_NAME%-% The “Grant Date” is: %%OPTION_DATE%-% The number of RSUs is: %%TOTAL_SHARES_GRANTED,'999,999,999'%-% Section 2. Restricted Period. (a) The “Restricted Period” for the RSUs granted by this Agreement shall begin on the Grant Date and end on June 20th of the year following the Grant Date. (such date, or such earlier date on which the RSU shall vest pursuant to this Agreement, being hereafter referred to as the “Vesting Date”); provided that the Participant has attended 75% of all meetings of the board to which Participant is elected or appointed held between the Grant Date and the earlier of the Vesting Date and the next annual meeting following the Grant Date at which the board is elected or appointed. The price at which the RSUs shall vest is the fair market value of Company common stock at closing on the business day prior to the Vesting Date, or the nearest prior trading day if the Vesting Date is not a trading day for the market on which Company common stock is traded. (b) Notwithstanding the foregoing provisions, the Restricted Period shall lapse and the RSUs shall become fully vested immediately upon (i) the death of the Participant or (ii) a Change in Control that occurs on or before the Participant’s Termination of Service. (c) If the Participant’s Termination of Service occurs prior to the earlier of (i) the next annual meeting following the Grant Date at which the board is elected or appointed or (ii) the Vesting Date, the Participant shall forfeit all right, title and interest in and to the RSUs as of such Termination of Service. Notwithstanding the foregoing language, transitioning from service as an elected member of a company’s board of directors to service as an appointed member of a non-legal board for such company is not a Termination of Service.

2 Rev 4-17-2023 Section 3. Settlement of RSUs. Delivery of Shares or other amounts under this Agreement and the Plan shall be subject to the following: (a) Delivery of Shares. The Company shall deliver to the Participant one Share free and clear of any restrictions in settlement of each of the vested and unrestricted RSUs within 30 days following the end of the Vesting Date. (b) Compliance with Applicable Laws. Notwithstanding any other term of this Agreement or the Plan, the Company shall have no obligation to deliver any Shares or make any other distribution of benefits under this Agreement or the Plan unless such delivery or distribution complies with all applicable laws and the applicable rules of any securities exchange or similar entity. (c) Certificates Not Required. To the extent that this Agreement and the Plan provide for the issuance of Shares, such issuance may be effected on a non-certificated basis, to the extent not prohibited by applicable law or the applicable rules of any securities exchange or similar entity. Section 4. Withholding. While awards to non-employee directors generally will not be subject to tax withholding requirements, the Company shall have the right to require the Participant (or if applicable, permitted assigns, heirs and Designated Beneficiaries) to remit to the Company an amount sufficient to satisfy any applicable statutory tax withholding requirements, if any, prior to the delivery date of any Shares in connection with the Award. Section 5. Non-Transferability of Award. The Award, or any portion thereof, is not transferable except as designated by the Participant by will or by the laws of descent and distribution or pursuant to a domestic relations order. Except as provided in the immediately preceding sentence, the Award shall not be assigned, transferred, pledged, hypothecated or otherwise disposed of by the Participant in any way whether by operation of law or otherwise, and shall not be subject to execution, attachment or similar process. Any attempt at assignment, transfer, pledge, hypothecation or other disposition of the Award contrary to the provisions hereof, or the levy of any attachment or similar process upon the Award, shall be null and void and without effect. Section 6. Stockholder Rights. Any dividends or other distributions declared payable on the Company’s Shares on or after the grant date of the RSUs until the RSUs vest or forfeit shall be credited notionally to the Participant in an amount equal to such declared dividends or other distributions on an equivalent number of the Shares of the Company (“Dividend Equivalents”). Dividend Equivalents so credited shall be paid if, and only to the extent that, the RSUs to which they relate vest, as provided under the terms of the Plan and this Agreement. Dividend Equivalents credited in respect to RSUs that are forfeited under the terms of the Plan and this Agreement are correspondingly forfeited. No interest or other earnings shall be credited on Dividend Equivalents. Vested Dividend Equivalents shall be paid in cash at the same time as the RSUs to which they relate vest and are converted into Shares. Other than as explicitly set forth above, the Participant shall not have any other rights of a Stockholder with respect to the RSUs, including but not limited to, voting rights, prior to the settlement of the RSUs pursuant to (a) above and issuance of Shares as provided herein.

3 Rev 4-17-2023 Section 7. Heirs and Successors. This Agreement shall be binding upon, and inure to the benefit of, the Company and its successors and assigns, and upon any person acquiring all or substantially all of the Company’s assets or business. If any rights of the Participant or benefits distributable to the Participant under this Agreement have not been settled or distributed at the time of the Participant’s death and have not been designated to pass to a certain beneficiary, such rights shall be provided to the legal representative of the estate of the Participant. Section 8. Administration. The authority to manage and control the operation and administration of this Agreement and the Plan shall be vested in the Committee, and the Committee shall have all powers with respect to this Agreement as it has with respect to the Plan. Any interpretation of this Agreement or the Plan by the Committee and any decision made by the Committee with respect to this Agreement or the Plan shall be final and binding on all persons. Section 9. Plan Governs. Notwithstanding anything in this Agreement to the contrary, this Agreement shall be subject to the terms of the Plan, a copy of which may be obtained by the Participant from the office of the secretary of the Company. This Agreement shall be subject to all interpretations, amendments, rules and regulations promulgated by the Committee from time to time. Notwithstanding any term of this Agreement to the contrary, in the event of any discrepancy between the corporate records of the Company and this Agreement, the corporate records of the Company shall control. Section 10. Not an Employment Contract. Neither the Award nor this Agreement shall confer on the Participant any rights with respect to continuance of employment or other service with the Company or a Subsidiary, nor shall they interfere in any way with any right the Company or a Subsidiary may otherwise have to terminate or modify the terms of the Participant’s employment or other service at any time. Section 11. Amendment. Subject to Section 14 and Section 15 below, this Agreement may be amended in accordance with the provisions of the Plan and may otherwise be amended in writing by the Participant and the Company without the consent of any other person. Section 12. Governing Law. This Agreement, the Plan and all actions taken in connection herewith and therewith shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to principles of conflict of laws, except as superseded by applicable federal law. Section 13. Validity. If any provision of this Agreement is determined to be illegal or invalid for any reason, said illegality or invalidity shall not affect the remaining parts hereof, but this Agreement shall be construed and enforced as if such illegal or invalid provision had never been included herein. Section 14. Section 409A Amendment. The Award is intended to be exempt from Code Section 409A and this Agreement shall be administered and interpreted in accordance with such intent. The Committee reserves the right (including the right to delegate such right) to unilaterally amend this Agreement without the consent of the Participant in order to maintain an exclusion from the application of, or to maintain compliance with, Code Section 409A; and the Participant hereby acknowledges and consents to such rights of the Committee. As provided in the Plan, in the event that this Award constitutes deferred compensation, the term Termination of Service shall be interpreted in a manner consistent with the term “separation from service” as defined under Code Section 409A. In addition, if the Participant is a “specified employee” at the time of such “separation from service,” delivery of Shares or other amounts payable on account of a “separation from service” shall be delayed six months to the extent required by Code Section 409A.

4 Rev 4-17-2023 Section 15. Clawback. The Award and any amount or benefit received under the Plan shall be subject to potential cancellation, recoupment, rescission, payback or other action in accordance with the terms of the Company’s Clawback Provision Policy as amended from time to time or any other applicable Company clawback policy (the “Policy”) or any applicable law, as may be in effect from time to time. The Participant hereby acknowledges and consents to the Company’s or a Subsidiary’s application, implementation and enforcement of (a) the Policy and any similar policy established by the Company or a Subsidiary that may apply to the Participant and (b) any provision of applicable law relating to cancellation, rescission, payback or recoupment of compensation, and agrees that the Company or a Subsidiary may take such actions as may be necessary to effectuate the Policy, any similar policy and applicable law, without further consideration or action. * * * * * IN WITNESS WHEREOF, the Company has caused this Agreement to be executed in its name and on its behalf, and the Participant acknowledges understanding and acceptance of, and agrees to, the terms of this Agreement, all as of the Grant Date. This Agreement and any amendments or supplements hereto may be executed in counterparts, each of which shall constitute an original, but taken together shall constitute a single contract. Signature may be in electronic format, including by electronic acknowledgement. HEARTLAND FINANCIAL USA, INC. Print Name: John K.

HEARTLAND FINANCIAL USA, INC. FINANCIAL STATEMENT COMPENSATION RECOUPMENT POLICY This Financial Statement Compensation Recoupment Policy (the “Policy”) provides for the recoupment of certain executive compensation in the event of an accounting restatement of Heartland Financial USA, Inc. (the “Company”) resulting from material noncompliance with financial reporting requirements under U.S. federal securities laws in accordance with the terms and conditions set forth herein. This Policy is intended to comply with the requirements of Section 10D of the Exchange Act (as defined below) and Section 5608 of the Nasdaq Listing Rules. 1. Definitions. For the purposes of this Policy, the following terms shall have the meanings set forth below. Capitalized terms used but not defined in this Policy shall have the meanings set forth in the Company’s 2020 Long- Term Incentive Plan (the “LTIP”), as amended or succeeded from time to time. (a) “Committee” means the Compensation and Human Capital Committee of the Board of Directors (“the Board”) or any successor committee thereof. (b) “Covered Compensation” means any Incentive-based Compensation “received” by a Covered Executive during the applicable Recoupment Period; provided that: (i) such Covered Compensation was received by such Covered Executive (A) after the Effective Date, (B) after he or she commenced service as an Executive Officer and (C) while the Company had a class of securities publicly listed on a United States national securities exchange; and (ii) such Covered Executive served as an Executive Officer at any time during the performance period applicable to such Incentive-based Compensation. For purposes of this Policy, Incentive-based Compensation is “received” by a Covered Executive during the fiscal period in which the Financial Reporting Measure applicable to such Incentive-based Compensation (or portion thereof) is attained, even if the payment or grant of such Incentive-based Compensation is made thereafter. (c) “Covered Executive” means any (i) current or former Executive Officer and (ii) any other employee of the Company and its subsidiaries designated by the Committee as subject to this Policy from time to time. (d) “Effective Date” means the date on which Section 5608 of the Nasdaq Listing Rules becomes effective. (e) “Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended. (f) “Executive Officer” means, with respect to the Company, (i) its president, (ii) its principal financial officer, (iii) its principal accounting officer (or if there is no such accounting officer, its controller), (iv) any vice- president in charge of a principal business unit, division or function (such as sales, administration or finance), (v) any other officer who performs a policy-making function for the Company (including any officer of the Company’s parent(s) or subsidiaries if they perform policy-making functions for the Company) and (vi) any other person who performs similar policy-making functions for the Company. Policy-making function is not intended to include policy-making functions that are not significant. The determination as to an individual’s status as an Executive Officer shall be made by the Committee and such determination shall be final, conclusive and binding on such individual and all other interested persons. (g) “Financial Reporting Measure” means any (i) measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, (ii) stock price measure or (iii) total shareholder return measure (and any measures that are derived wholly or in part from any measure referenced in clause (i), (ii) or (iii) above). For the avoidance of doubt, any such measure does not need to be presented within the Company’s financial statements or included in a filing with the U.S. Securities and

2 Exchange Commission to constitute a Financial Reporting Measure. (h) “Financial Restatement” means a restatement of the Company’s financial statements due to the Company’s material noncompliance with any financial reporting requirement under U.S. federal securities laws that is required in order to correct: (i) an error in previously issued financial statements that is material to the previously issued financial statements; or (ii) an error that would result in a material misstatement if (A) the error were corrected in the current period or (B) left uncorrected in the current period. For purposes of this Policy, a Financial Restatement shall not be deemed to occur in the event of a revision of the Company’s financial statements due to an out-of-period adjustment (i.e., when the error is immaterial to the previously issued financial statements and the correction of the error is also immaterial to the current period) or a retrospective (1) application of a change in accounting principles; (2) revision to reportable segment information due to a change in the structure of the Company’s internal organization; (3) reclassification due to a discontinued operation; (4) application of a change in reporting entity, such as from a reorganization of entities under common control; or (5) revision for stock splits, reverse stock splits, stock dividends or other changes in capital structure. (j) “Incentive-based Compensation” means any compensation (including, for the avoidance of doubt, any cash or equity or equity-based compensation, whether deferred or current) that is granted, earned and/or vested based wholly or in part upon the achievement of a Financial Reporting Measure. For purposes of this Policy, “Incentive-based Compensation” shall also be deemed to include any amounts which were determined based on (or were otherwise calculated by reference to) Incentive-based Compensation (including, without limitation, any amounts under any long-term disability, life insurance or supplemental retirement or severance plan or agreement or any notional account that is based on Incentive-based Compensation, as well as any earnings accrued thereon). (k) “Nasdaq” means the NASDAQ Global Select Market, or any successor thereof. (l) “Recoupment Period” means the three fiscal years completed immediately preceding the date of any applicable Recoupment Trigger Date. Notwithstanding the foregoing, the Recoupment Period additionally includes any transition period (that results from a change in the Company’s fiscal year) within or immediately following those three completed fiscal years, provided that a transition period between the last day of the Company’s previous fiscal year end and the first day of its new fiscal year that comprises a period of nine (9) to twelve (12) months would be deemed a completed fiscal year. (m) “Recoupment Trigger Date” means the earlier of (i) the date that the Board (or a committee thereof or the officer(s) of the Company authorized to take such action if Board action is not required) concludes, or reasonably should have concluded, that the Company is required to prepare a Financial Restatemen t, and (ii) the date on which a court, regulator or other legally authorized body directs the Company to prepare a Financial Restatement. 2. Recoupment of Erroneously Awarded Compensation. (a) In the event of a Financial Restatement, if the amount of any Covered Compensation received by a Covered Executive (the “Awarded Compensation”) exceeds the amount of such Covered Compensation that would have otherwise been received by such Covered Executive if calculated based on the Financial Restatement (the “Adjusted Compensation”), the Company shall reasonably promptly recover from such Covered Executive an amount equal to the excess of the Awarded Compensation over the Adjusted Compensation, each calculated on a pre-tax basis (such excess amount, the “Erroneously Awarded Compensation”). (b) If (i) the Financial Reporting Measure applicable to the relevant Covered Compensation is stock price or total shareholder return (or any measure derived wholly or in part from either of such measures) and (ii) the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in the Financial Restatement, then the amount of Erroneously Awarded Compensation shall be determined (on a pre-tax basis) based on the Company’s reasonable estimate of the effect of the Financial

3 Restatement on the Company’s stock price or total shareholder return (or the derivative measure thereof) upon which such Covered Compensation was received. (c) For the avoidance of doubt, the Company’s obligation to recover Erroneously Awarded Compensation is not dependent on (i) if or when the restated financial statements are filed or (ii) any fault of any Covered Executive for the accounting errors or other actions leading to a Financial Restatement. (d) Notwithstanding anything to the contrary in Sections 2(a) through (c) hereof, the Company shall not be required to recover any Erroneously Awarded Compensation if both (x) the conditions set forth in either of the following clauses (i) or (ii) are satisfied and (y) the Committee (or a majority of the independent directors serving on the Board) has determined that recovery of the Erroneously Awarded Compensation would be impracticable : (i) the direct expense paid to a third pa rty to assist in enforcing the recovery of the Erroneously Awarded Compensation under this Policy would exceed the amount of such Erroneously Awarded Compensation to be recovered; provided that, before concluding that it would be impracticable to recover any amount of Erroneously Awarded Compensation pursuant to this Section 2 (d), the Company shall have first made a reasonable attempt to recover such Erroneously Awarded Compensation, document such reasonable attempt(s) to make such recovery and provide that documentation to the Nasdaq; (ii) recovery of the Erroneously Awarded Compensation would likely cause an otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of the Company, to fail to meet the requirements of Sections 401(a)(13) or 411(a) of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). (e) The Company shall not indemnify any Covered Executive, directly or indirectly, for any losses that such Covered Executive may incur in connection with the recovery of Erroneously Awarded Compensation pursuant to this Policy, including through the payment of insurance premiums or gross-up payments. (f) The Committee shall determine, in its sole discretion, the manner and timing in which any Erroneously Awarded Compensation shall be recovered from a Covered Executive in accordance with applicable law, including, without limitation, by (i) requiring reimbursement of Covered Compensation previously paid in cash; (ii) seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other disp osition of any equity or equity-based awards; (iii) offsetting the Erroneously Awarded Compensation amount from any compensation otherwise owed by the Company or any of its affiliates to the Covered Executive; (iv) cancelling outstanding vested or unvested equity or equity-based awards; and/or (v) taking any other remedial and recovery action permitted by applicable law. For the avoidance of doubt, except as set forth in Section 2(d), in no event may the Company accept an amount that is less than the amount of Erroneously Awarded Compensation; provided that, to the extent necessary to avoid any adverse tax consequences to the Covered Executive pursuant to Section 409A of the Code, any offsets against amounts under any nonqualified deferred compensation plans (as defined under Section 409A of the Code) shall be made in compliance with Section 409A of the Code. 3. Administration. This Policy shall be administered by the Committee. All decisions of the Committee shall be final, conclusive and binding upon the Company and the Covered Executives, their beneficiaries, executors, administrators and any other legal representative. The Committee shall have full power and authority to (i) administer and interpret this Policy; (ii) correct any defect, supply any omission and reconcile any inconsistency in this Policy; and (iii) make any other determination and take any other action that the Committee deems necessary or desirable for the administration of this Policy and to comply with applicable law (including Section 10D of the Exchange Act) and applicable stock market or exchange rules and regulations. Notwithstanding anything to the contrary contained herein, to the extent permitted by Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules, the Board may, in its sole discretion, at any time and from time to time, administer this Policy in the same manner as the Committee. 4. Amendment/Termination. Subject to Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules, this Policy may be amended or terminated by the Committee at any time. To the extent that any applicable law, or stock market or exchange rules or regulations require recovery of Erroneously Awarded Compensation in circumstances in addition to those specified herein, nothing in this Policy shall be deemed to limit

4 or restrict the right or obligation of the Company to recover Erroneously Awarded Compensation to the fullest extent required by such applicable law, stock market or exchange rules and regulations. Unless otherwise required by applicable law, this Policy shall no longer be effective from and after the date that the Company no longer has a class of securities publicly listed on a United States national securities exchange. 5. Interpretation. Notwithstanding anything to the contrary herein, this Policy is intended to comply with the requirements of Section 10D of the Exchange Act and Section 5608 of the Nasdaq Listing Rules (and any applicable regulations, administrative interpretations or stock market or exchange rules and regulations adopted in connection therewith). The provisions of this Policy shall be interpreted in a manner that satisfies such requirements and this Policy shall be operated accordingly. If any provision of this Policy would otherwise frustrate or conflict with this intent, the provision shall be interpreted and deemed amended so as to avoid such conflict. 6. Other Compensation Clawback/Recoupment Rights. Any right of recoupment under this Policy is in addition to, and not in lieu of: (i) any other remedies, rights or requirements with respect to the clawback or recoupment of any compensation that may be available to the Company pursuant to the terms of any other recoupment or clawback policy of the Company (or any of its affiliates) that may be in effect from time to time , including without limitation, the Company’s Claw Back Provision Policy ; (ii) any provisions in any employment agreement, offer letter, equity plan, equity award agreement or similar plan or agreement; and (iii) any other legal remedies available to the Company, as well as applicable law, stock market or exchange rules, listing standards or regulations; provided, however, that any amounts recouped or clawed back under any other policy that would be recoupable under this Policy shall count toward any required clawback or recoupment under this Policy and vice versa. 7. Exempt Compensation. Notwithstanding anything to the contrary herein, the Company has no obligation to seek recoupment of amounts paid to a Covered Executive which are granted, vested or earned based solely upon the occurrence or non-occurrence of nonfinancial events. Such exempt compensation includes, without limitation, base salary, time-vesting awards, compensation awarded on the basis of the achievement of metrics that are not Financial Reporting Measures or compensation awarded solely at the discretion of the Committee or the Board, provided that such amounts are in no way contingent on, and were not in any way granted on the basis of, the achievement of any Financial Reporting Measure performance goal. 8. Miscellaneous. (a) Any applicable award agreement or other document setting forth the terms and conditions of any compensation covered by this Policy shall be deemed to include the restrictions imposed herein and incorporate this Policy by reference and, in the event of any inconsistency, the terms of this Policy will govern. For the avoidance of doubt, this Policy applies to all compensation that is received on or after the Effective Date, regardless of the date on which the award agreement or other document setting forth the terms and conditions of the Covered Executive’s compensation became effective, including, without limitation, compensation received under the LTIP and any successor plan thereto. (b) This Policy shall be binding and enforceable against all Covered Executives and their beneficiaries, heirs, executors, administrators or other legal representatives. (c) All issues concerning the construction, validity, enforcement and interpretation of this Policy and all related documents, including, without limitation, any employment agreement, offer letter, equity award agreement or similar agreement, shall be governed by, and construed in accordance with, the laws of the State of Colorado, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Colorado or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Colorado. (d) The Covered Executives, their beneficiaries, executors, administrators and any other legal representative and the Company shall initially attempt to resolve all claims, disputes or controversies arising under, out of or in connection with this Policy by conducting good faith negotiations amongst themselves. The federal and state courts sitting within the State of Colorado shall be the sole and exclusive forums for any and all disputes, claims, or causes of action arising from or relating to the enforcement, performance or interpretation of this Policy. The Covered Executives, their beneficiaries, executors, administrators and any other legal representative and the

5 Company, shall not commence any suit, action or other proceeding arising out of or based upon this Agreement except in the United States District Court for the District of Colorado or any Colorado court, and hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that such party is not subject to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Policy or the subject matter hereof may not be enforced in or by such courts. To the fullest extent permitted by law, the Covered Executives, their beneficiaries, executors, administrators, and any other legal representative, and the Company, shall waive (and shall hereby be deemed to have waived) the right to resolve any such dispute through a trial by jury. (e) If any provision of this Policy is determined to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted by applicable law and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to any limitations required under applicable law.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations - Heartland Financial USA, Inc. ("HTLF") is a bank holding company with locations in Iowa, Illinois, Wisconsin, New Mexico, Arizona, Colorado, Montana, Minnesota, Kansas, Missouri, Texas and California. The principal services of HTLF, which are provided through HTLF Bank, are FDIC-insured deposit accounts and related services, and loans to businesses and consumers. The loans consist primarily of commercial and industrial, owner-occupied commercial real estate, non-owner occupied commercial real estate, real estate construction, agricultural and agricultural real estate, residential real estate and consumer loans.

Principles of Presentation - The consolidated financial statements include the accounts of HTLF and its subsidiaries: HTLF Bank; DB&T Community Development Corp.; Heartland Community Development, Inc.; Heartland Financial USA, Inc. Insurance Services; Heartland Financial Statutory Trust IV; Heartland Financial Statutory Trust V; Heartland Financial Statutory Trust VI; Heartland Financial Statutory Trust VII; Morrill Statutory Trust I; Morrill Statutory Trust II; Sheboygan Statutory Trust I, CBNM Capital Trust I, Citywide Capital Trust III, Citywide Capital Trust IV, Citywide Capital Trust V, OCGI Statutory Trust III, OCGI Capital Trust IV, BVBC Capital Trust II, and BVBC Capital Trust III. All HTLF’s subsidiaries are wholly-owned as of December 31, 2023.

As of December 31, 2023, HTLF Bank and its respective bank brands listed below operated as divisions of HTLF Bank:

•Arizona Bank & Trust

•Bank of Blue Valley

•Citywide Banks

•Dubuque Bank & Trust

•First Bank & Trust

•Illinois Bank & Trust

•Minnesota Bank & Trust

•New Mexico Bank & Trust

•Premier Valley Bank

•Rocky Mountain Bank

•Wisconsin Bank & Trust

During the first quarter of 2023, HTLF reclassified swap and loan syndication income (collectively, "capital markets fees") to capital markets fees from other noninterest income on the consolidated statements of income, and all prior periods have been adjusted.

During the second quarter of 2023, HTLF reclassified Federal Deposit Insurance Corporation ("FDIC") insurance premiums to FDIC insurance assessments from professional fees on the consolidated statements of income, and all prior periods have been adjusted.

In the second quarter of 2023, HTLF amended and restated its Certificate of Incorporation and filed Certificates of Elimination with the state of Delaware with respect to Series A, B, C, and D preferred stock issuances, which returned these previously designated shares to authorized but unissued. The following shows the details of Series A, B, C and D preferred stock at December 31, 2022:

•Series A Junior Participating preferred stock-par value $1 per share; authorized 16,000 shares; none issued or outstanding at December 31, 2022

•Series B Fixed Rate Cumulative Perpetual Preferred Stock-par value $1 per share; 81,698 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

•Series C Senior Non-Cumulative Perpetual Preferred Stock-par value $1 per share; 81,698 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

•Series D Senior Non-Cumulative Perpetual Convertible Preferred Stock-par value $1 per share; 3,000 shares authorized at December 31, 2022; none issued or outstanding at December 31, 2022

After the cancellation of Series A, B, C and D preferred shares, total undesignated preferred shares authorized increased to 188,500 from 6,104 at December 31, 2022, of which none were issued or outstanding at both December 31, 2023 and December 31, 2022.

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and prevailing practices within the banking industry. In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheets and revenues and expenses for the years then ended. Actual results could differ significantly from those estimates. A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for credit losses.

Business Combinations - HTLF applies the acquisition method of accounting in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 805, Business Combinations. Under the acquisition method, HTLF recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at fair value as of the acquisition date, with the acquisition-related transaction costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective.

Cash and Cash Equivalents - For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits held at the Federal Reserve Bank, federal funds sold to other banks and other short-term investments. Generally, federal funds are purchased and sold for one-day periods.

Trading Securities - Trading securities represent those securities HTLF intends to actively trade and are stated at fair value with changes in fair value reflected in noninterest income. HTLF had no trading securities at both December 31, 2023 and 2022.

Available for Sale ("AFS") Debt Securities and Equity Securities - Available for sale securities consist of those securities not classified as held to maturity or trading, which management intends to hold for indefinite periods of time or that may be sold in response to changes in interest rates, prepayments or other similar factors. Available for sale securities are stated at fair value with any unrealized gain or loss, net of applicable income tax, reported as a separate component of stockholders’ equity. Security premiums and discounts are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

Realized securities gains or losses on securities sales (using a specific identification method) are included in securities gains, net in the consolidated statements of income.

Equity securities include Community Reinvestment Act funds with readily determinable fair values and are carried at fair value. Certain equity securities do not have readily determinable fair values, such as Federal Reserve Bank stock and Federal Home Loan Bank stock, which are held for debt and regulatory purposes and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. HTLF did not record any impairment or other adjustments to the carrying amount of these investments during the years ended December 31, 2023, and December 31, 2022.

Allowance for Credit Losses on AFS Debt Securities - HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, with regard to debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the

value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

The decline in fair value of an AFS debt security due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes. Although these evaluations involve judgment, an unrealized loss in the fair value of a debt security is generally considered to not be related to credit when the fair value of the security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration in the financial condition of the issuer, and HTLF does not intend to sell nor does it believe it will be required to sell the security before the recovery of its cost basis. HTLF had no allowance for credit losses on AFS debt securities recorded at December 31, 2023, and December 31, 2022.

Securities Held to Maturity - Securities which HTLF has the ability and positive intent to hold to maturity are classified as held to maturity. Such securities are stated at amortized cost, adjusted for premiums and discounts that are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

Allowance for Credit Losses on Held to Maturity Debt Securities - HTLF measures expected credit losses on held to maturity debt securities on a collective basis based on security type. The estimate of expected credit losses considers historical credit information that is adjusted for current conditions and supportable forecasts. HTLF's held to maturity debt securities consist primarily of investment grade obligations of states and political subdivisions. The forecast and forecast period used in the calculation of the allowance for credit losses for loans is used in calculating the allowance for credit losses on held to maturity debt securities. HTLF had no allowance for credit losses on held to maturity debt securities recorded at both December 31, 2023, and December 31, 2022.

Loans Held to Maturity - Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount outstanding, net of cumulative charge-offs, unamortized net deferred loan origination fees and costs and unamortized premiums or discounts on purchased loans. HTLF has a loan policy which establishes the credit risk appetite, lending standards and underwriting criteria designed so that HTLF may extend credit in a prudent and sound manner. The HTLF loan policy is reviewed and approved on a regular basis. A reporting system supplements the review process by providing management and the board with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans.

HTLF originates commercial and industrial loans and owner occupied commercial real estate loans for a wide variety of business purposes, including lines of credit for capital and operating purposes and term loans for real estate and equipment purchases. Non-owner occupied commercial real estate loans provide financing for various non-owner occupied or income producing properties. Real estate construction loans are generally short-term or interim loans that provide financing for acquiring or developing commercial income properties, multi-family projects or single-family residential homes. Agricultural and agricultural real estate loans provide financing for capital improvements and farm operations, as well as livestock and machinery purchases. Residential real estate loans are originated for the purchase or refinancing of single-family residential properties. Consumer loans include loans for motor vehicles, home improvement, home equity and personal lines of credit.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. HTLF’s policy is to discontinue the accrual of interest income on any loan when, in the opinion of management, there is a reasonable doubt as to the timely collection of the interest and principal, normally when a loan is 90 days past due. When interest accruals are deemed uncollectible, interest credited to income in the current year is reversed and interest accrued in prior years is charged to the allowance for credit losses. A loan can be restored to accrual status if the borrower has resumed paying the full amount of the scheduled contractual interest and principal payments on the loan, and (1) all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period of time, and (2) there is a sustained period of repayment performance (generally a minimum of six months) by the borrower in accordance with the scheduled contractual terms.

Allowance for Credit Losses for Loans - The allowance for credit losses is a valuation account that is deducted from the loans held to maturity amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged-off against the allowance when management believes the loan balance is deemed to be uncollectible. Provisions for credit losses for loans and recoveries on loans previously charged-off by HTLF are added back to the allowance.

HTLF's allowance model is designed to consider the current contractual term of the loan, defined as starting as of the most recent renewal date and ending at maturity date.

Management's estimation of expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts, including expected defaults and prepayments. Historical loss experience is generally the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms and differences in economic conditions, both current conditions and reasonable and supportable forecasts. If HTLF is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it is required to estimate expected credit losses for the remaining life using an approach that reverts to historical credit loss information. The components of the allowance for credit losses are described more specifically below.

Quantitative Factors

The quantitative component of the allowance for credit losses is measured using historical loss experience using a look back period, currently over the most recent 16 years, on a pool basis for loans with similar risk characteristics. HTLF utilizes third-party software to calculate the expected credit losses using two separate methodologies. For certain commercial and agricultural loans, the expected credit losses are calculated through a transition matrix model derived probability of default and loss given default methodology. The transition matrix model determines the life of loan probability of default using the historical transitions of loans between risk ratings and through default. The probability of default and loss given default methodology has been developed using HTLF’s historical loss experience over the look back period. For smaller commercial and agricultural loans, residential real estate loans and consumer loans, a lifetime average historical loss rate is established for each pool of loans based upon an average loss rate calculated using HTLF historical loss experience over the look back period.

The risks in the commercial and industrial loan portfolio include the unpredictability of the cash flow of the borrowers and the variability in the value of the collateral securing the loans. Owner occupied commercial real estate loans depend upon the cash flow of the borrowers and the collateral value of the real estate. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover the operating expenses and debt service. Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project. Additionally, real estate construction loans have a greater risk of default in a weaker economy because the source of repayment relies on the successful and timely completion of the project. Agricultural and agricultural real estate loans depend upon the profitable operation or management of the farm property securing the loan. Loans secured by farm equipment, livestock or crops may not provide an adequate source of repayment because of damage or depreciation. Residential real estate loans depend upon the borrower's ability to repay the loan and the underlying collateral value. Consumer loans depend upon the borrower's personal financial circumstances and continued financial stability.

If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and on nonaccrual status are individually assessed using a collateral dependency calculation. A loan is collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. The impairment will be recognized by creating a specific reserve against the loan with a corresponding charge to provision expense. In most cases, the specific reserve will be charged off in the same quarter the loss is probable. In some cases, when HTLF believes certain loans do not share the same risk characteristics with other loans in the pool, the standard allows for these loans to be individually assessed. All individually assessed loan calculations are completed at least semi-annually.

Qualitative Factors

HTLF's allowance methodology also has a qualitative component, the purpose of which is to provide management with a means to take into consideration changes in current conditions that could potentially have an effect on the level of recognized loan losses, that otherwise fail to show up in the quantitative analysis performed in determining its base loan loss rates.

HTLF utilizes the following qualitative factors:

•changes in lending policies and procedures

•changes in the nature of loans

•experience and ability of management

•changes in the credit quality of the loan portfolio

•risk in acquired portfolios

•concentrations of credit

The qualitative factors for changes in lending policies and procedures, management and acquired portfolios are weighted as one factor. The other qualitative factors noted above are equally weighted as individual factors.

The qualitative adjustments are based on the comparison of the current condition to the average condition over the look back period. The adjustment amount can be either positive or negative depending on whether the current condition is better or worse than the historical average. HTLF incorporates the adjustments for changes in current conditions using an overlay approach. The adjustments are applied as a percentage adjustment in addition to the calculated historical loss rates of each pool. These adjustments reflect the extent to which HTLF expects current conditions to differ from the conditions that existed for the period over which historical information was evaluated. HTLF utilizes an anchoring approach to determine the minimum and maximum amount of qualitative allowance for credit losses, which is determined by comparing the highest and lowest historical rate to the current quantitative allowance rate to calculate the rate for the adjustment.

Economic Forecasting

The allowance for credit losses estimate incorporates a reasonable and supportable forecast of various macro-economic indices over the remaining life of HTLF’s assets. HTLF utilizes an overlay approach for its economic forecasting component, similar to the method utilized for the qualitative factors. The length of the reasonable and supportable forecast period is a judgmental determination based on the level to which the entity can support its forecast of economic conditions that drive its estimate of expected loss. HTLF compares forecasted macro-economic indices, such as unemployment and gross domestic product, to the economic conditions that existed over HTLF's look back period.

HTLF uses Moody's baseline economic forecast scenario, which is updated quarterly in HTLF's methodology, and considers other Moody's forecast scenarios to support the economic forecast component of the allowance for credit losses. The economic forecast reverts to the historical mean immediately at the end of the reasonable and supportable forecast period. HTLF utilized a one-year reasonable and supportable forecast period for the calculation of the December 31, 2023, and December 31, 2022, allowance for credit losses.

It is expected that actual economic conditions will, in many cases, differ from forecasts because the ultimate outcomes during the forecast period may be affected by events that were unforeseen, such as economic disruption and fiscal or monetary policy actions, which are exacerbated by longer forecasting periods. This uncertainty would be relevant to the entity’s confidence level as to the outcomes being forecasted. That is, an entity is likely less confident in the ultimate outcome of events that will occur at the end of the forecast period as compared to the beginning. As a result, actual future economic conditions may not be an effective indicator of the quality of management’s forecasting process, including the length of the forecast period.

Financial Difficulty Modifications - Any loans that are modified are reviewed by HTLF to identify if a financial difficulty modification has occurred, which is when HTLF modifies a loan related to a borrower experiencing financial difficulties. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status. The modification of the terms of such loans includes one or a combination of the following: a reduction of the stated interest rate of the loan, an extension of the maturity date, a permanent reduction of the recorded investment of the loan, or an other-than-insignificant payment delay. The adoption of ASU 2022-02 on January 1, 2023 eliminated the recognition and measurement of TDRs and enhanced disclosures for modifications to loans related to borrowers experiencing financial difficulties. See Note Four to the consolidated financial statements for additional detail regarding the adoption of ASU 2022-02.

Loans Held for Sale - Loans held for sale are stated at the lower of cost or fair value on an aggregate basis. Gains or losses on sales are recorded in noninterest income. Direct loan origination costs and fees are deferred at origination of the loan. These deferred costs and fees are recognized in noninterest income as part of the gain or loss on sales of loans upon sale of the loan.

At December 31, 2023 and 2022, loans held for sale primarily consisted of 1-4 family residential mortgages.

Allowance for Credit Losses on Unfunded Loan Commitments - HTLF estimates expected credit losses over the contractual term of the loan for the unfunded portion of the loan commitment that is not unconditionally cancellable by HTLF using the same collective allowance methodology for credit losses for loans described above. Management uses an estimated average utilization rate to determine the exposure at default. The allowance for unfunded commitments is recorded in the Accrued Expenses and Other Liabilities section of the consolidated balance sheets.

Mortgage Servicing and Transfers of Financial Assets - Prior to dissolving its mortgage operations in 2023, HTLF regularly sold residential mortgage loans to others, primarily government sponsored entities, on a non-recourse basis. Sold loans are not included in the accompanying consolidated balance sheets. HTLF generally retained the right to service the sold loans for a fee prior to the sale of its mortgage servicing rights portfolio in the first quarter of 2023. First Bank & Trust, a division of HTLF Bank, serviced mortgage loans primarily for government sponsored entities with aggregate unpaid principal balance of $0 and $725.9 million, at December 31, 2023 and 2022, respectively.

Premises, Furniture and Equipment, net - Premises, furniture and equipment are stated at cost less accumulated depreciation. The provision for depreciation of premises, furniture and equipment is determined by straight-line and accelerated methods over the estimated useful lives of 18 to 39 years for buildings, 15 years for land improvements and 3 to 7 years for furniture and equipment.

Premises, Furniture and Equipment Held for Sale - Premises, furniture and equipment are stated at the estimated fair value less disposal costs. Subsequent write-downs and gains or losses on the sales are recorded to gain (loss) on sales/valuation of assets, net.

Other Real Estate - Other real estate represents property acquired through foreclosures and settlements of loans. Property acquired is recorded at the estimated fair value of the property less disposal costs. The excess of carrying value over fair value less disposal costs is charged against the allowance for credit losses. Subsequent write downs estimated on the basis of later valuations and gains or losses on sales are charged to gain (loss) on sales/valuation of assets, net. Expenses incurred in maintaining such properties are charged to other real estate and loan collection expenses.

Goodwill - Goodwill represents the excess of the purchase price of acquired subsidiaries’ net assets over their fair value at the purchase date. HTLF assesses goodwill for impairment annually, and more frequently if events occur which may indicate possible impairment, and assesses goodwill at the reporting unit level, also giving consideration to overall enterprise value as part of that assessment.

In evaluating goodwill for impairment, HTLF first assesses qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If HTLF concludes that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then no further testing of goodwill assigned to the reporting unit is required. However, if HTLF concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then HTLF performs a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to recognize, if any. In addition, the income tax effects of tax-deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. A goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.

Core Deposit Intangibles and Customer Relationship Intangibles, Net - Core deposit intangibles are amortized over 8 to 18 years on an accelerated basis. Customer relationship intangibles were amortized over 22 years on an accelerated basis. Annually, HTLF reviews these intangible assets for events or circumstances that may indicate a change in the recoverability of the underlying basis.

Servicing Rights, Net - Mortgage and commercial servicing rights associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and recorded on the consolidated statements of income as a component of gains on sale of loans held for sale. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned.

First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing portfolio in the first quarter of 2023, and the value of the mortgage servicing rights was derecognized on the consolidated balance sheet. In prior periods, the carrying values of these rights were reviewed quarterly for impairment based on the calculation of their fair value as performed by an outside third-party. For purposes of measuring impairment, the rights were stratified into certain risk characteristics including loan type and loan term. At December 31, 2022, no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 15 years, and no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 30 years.

Cash Surrender Value on Life Insurance - HTLF and its subsidiaries have purchased life insurance policies on the lives of certain officers. The one-time premiums paid for the policies, which coincide with the initial cash surrender value, are recorded as an asset. Increases or decreases in the cash surrender value, other than proceeds from death benefits, are recorded as noninterest income in income on bank owned life insurance. Proceeds from death benefits first reduce the cash surrender value attributable to the individual policy and then any additional proceeds are recorded in other noninterest income.

Income Taxes - HTLF and its subsidiaries file a consolidated federal income tax return and separate or combined income or franchise tax returns as required by the various states. HTLF recognizes certain income and expenses in different time periods for financial reporting and income tax purposes. The provision for deferred income taxes is based on an asset and liability

approach and represents the change in deferred income tax accounts during the year, including the effect of enacted tax rate changes. A valuation allowance is provided to reduce deferred tax assets if their expected realization is deemed not to be more likely than not.

A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. HTLF recognizes interest and penalties related to income tax matters in income tax expense.

Derivative Financial Instruments - HTLF uses derivative financial instruments as part of its interest rate risk management, which includes interest rate swaps, certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. FASB ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC 815, HTLF records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives used to manage the exposure to changes in the fair value of a recognized asset or liability on the consolidated balance sheets are fair value hedges. To qualify for hedge accounting, HTLF must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship. Hedge ineffectiveness, if any, is measured periodically throughout the life of the hedging relationship.

For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in the fair value of the derivative, if any, is recognized immediately in other noninterest income. HTLF assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instrument with the cumulative changes in cash flows of the designated hedged item or transaction. No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness. In the first quarter of 2023 HTLF terminated its cash flow hedges. It was determined that the forecasted transactions remain probable, so the unrealized gains at termination were kept in accumulated comprehensive income and are being amortized into income over the remaining life of the forecasted transaction.

HTLF had multiple fair value hedging relationships at December 31, 2023. HTLF uses hedge accounting in accordance with ASC 815. For hedges where the fair value change in the loan portfolio is being hedged, unrealized gains and losses representing the change in fair value of the derivative and the change in fair value of the risk being hedged on the related loan are being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. For hedges where the fair value change in the investment portfolio are being hedged, the change in the fair value of the derivative and the change in the fair value of the risk being hedged on the related investments is being recorded in interest income on the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

HTLF also has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income.

HTLF does not use derivatives for speculative purposes. Derivatives not designated as hedges are not speculative and are used to manage HTLF’s exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements of ASC 815.

Mortgage Derivatives - HTLF uses interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities. These commitments are considered derivative instruments. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. As of December 31, 2023, HTLF was winding out of this activity due to dissolving its mortgage operations.

Fair Value Measurements - Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using discounted cash flow or other valuation techniques. Inputs into the valuation methods are subjective in nature, involve uncertainties, and require judgment and therefore cannot be determined with precision. Accordingly, the derived fair value estimates presented herein are not necessarily indicative of the amounts HTLF could realize in a current market exchange. Assets and liabilities are categorized into three levels based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine the fair value. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. HTLF's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Below is a brief description of each fair value level:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Segment Reporting - Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), which is the Chief Executive Officer of HTLF, in deciding how to allocate resources and assess the financial and operating performance of HTLF. HTLF’s operating segments provide, and primarily derive revenue, through full service commercial and consumer banking. HTLF has determined that the economic characteristics, operating models, performance metrics, suite of products and services, customer base, and regulatory requirements are similar for its operating segments and has therefore aggregated them into one reportable segment.

Treasury Stock - Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price. When treasury stock is reissued, any difference between the sales proceeds, or fair value when issued for business combinations, and the cost is recognized as a charge or credit to capital surplus. HTLF had no treasury stock at December 31, 2023 and December 31, 2022.

Trust Department Assets - Property held for customers in fiduciary or agency capacities is not included in the accompanying consolidated balance sheets because such items are not assets of HTLF Bank.

Earnings Per Share - Basic earnings per share is determined using net income available to common stockholders and weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average common shares and assumed incremental common shares issued. Amounts used in the determination of basic and diluted earnings per share for the years ended December 31, 2023, 2022 and 2021, are shown in the table below, dollars and number of shares in thousands, except per share data:

	2023		2022		2021

Subsequent Events - HTLF has evaluated subsequent events that may require recognition or disclosure through the filing date of this Annual Report on Form 10-K with the SEC.

Subsequent to December 31, 2023, in February of 2024, HTLF announced that HTLF Bank had signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024.

Effect of New Financial Accounting Standards

ASU 2022-01

In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method," which expands the current last-of-layer method by allowing multiple hedged layers to be designated for a single closed portfolio of financial assets or one or more beneficial interests secured by a portfolio of financial instruments. HTLF adopted this ASU on January 1, 2023, and these amendments were applied prospectively.

ASU 2022-02

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." These amendments eliminate the troubled debt restructurings ("TDR") recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, these amendments require that an entity disclose current-period gross charge-offs by year of origination for loans receivable within the scope of Subtopic 326-20. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These amendments should be applied prospectively. If an entity elects to early adopt ASU 2022-02 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. An entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. HTLF adopted this ASU on January 1, 2023, as required, and the adoption did not have a material impact on its results of operations, financial position or liquidity.

ASU 2023-02

In March 2023, the FASB issued ASU 2023-02 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Task Force)." ASU 2023-02 expands the permitted use of the proportional amortization method, which is currently only available to low-income housing tax credit investments, to other tax equity investments if certain conditions are met. Under the proportional

amortization method, the initial cost of an investment is amortized in proportion to the income tax benefits received and both the amortization of the investment and the income tax benefits received are recognized as a component of income tax expense. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and must be applied on either a modified retrospective or a retrospective basis. The adoption of this amendment is not expected to have a material impact on the results of operations or financial position.

ASU 2023-06

In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." The amendments in this Update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to, or technical corrections of, the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The amendments in this ASU are not expected to have a material impact on the results of operations or financial position.

During the third quarter of 2022, HTLF transferred taxable municipal bonds with an amortized cost basis of $934.5 million and fair value of $748.3 million from available for sale to held to maturity. On the date of the transfer, accumulated other comprehensive income (loss) included $186.3 million of net unrealized losses, after tax, attributable to these securities, and the net unrealized losses will be amortized into interest income over the remaining life of the transferred securities. The bonds were transferred at fair value at the date of transfer.

As of December 31, 2023, HTLF had $28.0 million compared to $33.0 million at December 31, 2022, of accrued interest receivable, which is included in other assets on the consolidated balance sheets. HTLF does not consider accrued interest receivable in the carrying amount of financial assets held at amortized cost basis or in the allowance for credit losses calculation.

The following tables summarize, in thousands, the amount of unrealized losses, defined as the amount by which cost or amortized cost exceeds fair value, and the related fair value of investments with unrealized losses in HTLF's securities portfolio as of December 31, 2023, and December 31, 2022. The investments were segregated into two categories: those that have been in a continuous unrealized loss position for less than 12 months and those that have been in a continuous unrealized loss position for 12 or more months. The reference point for determining how long an investment was in an unrealized loss position was December 31, 2023, and December 31, 2022, respectively. For securities transferred to held to maturity during the third quarter of 2022, the reference point was the date of transfer.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

The unrealized losses on HTLF's mortgage and asset-backed securities are the result of changes in market interest rates or widening of market spreads after the initial purchase of the securities. The losses are not related to concerns regarding the underlying credit of the issuers or the underlying collateral. It is expected that the securities will not be settled at a price less than the amortized cost of the investment. Because the decline in fair value is attributable to changes in interest rates or widening market spreads and not credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the years ended December 31, 2023 and December 31, 2022.

The unrealized losses on HTLF's obligations of states and political subdivisions are the result of changes in market interest rates or widening of market spreads after the initial purchase of the securities. Management monitors the published credit ratings of these securities and the stability of the underlying municipalities. Because the decline in fair value is attributable to changes in interest rates or widening market spreads due to insurance company downgrades and not underlying credit quality, and because HTLF has the intent and ability to hold these investments until a market price recovery or to maturity and does not believe it will be required to sell the securities before maturity, no credit losses were recognized on these securities during the years ended December 31, 2023 and December 31, 2022.

In the first quarter of 2022, HTLF sold two obligations of states and political subdivisions securities from the held to maturity portfolio. Because the evaluation of the underlying credit quality of the individual securities indicated significant deterioration, it was unlikely HTLF would recover the remaining basis of the securities prior to maturity and therefore inconsistent with HTLF's original intent upon purchase and classification of these held to maturity securities. The carrying value of these securities was $2.2 million, and the associated gross gains were $100,000.

The following table summarizes, in thousands, the carrying amount of HTLF's held to maturity debt securities by investment rating as of December 31, 2023 and December 31, 2022, which are updated quarterly and used to monitor the credit quality of the securities:

	December 31, 2023		December 31, 2022
Rating
AAA	$	88,550	$	79,598
AA, AA+, AA-	583,816		588,354
A+, A, A-	139,658		136,624
BBB	20,133		20,623
Not Rated	6,084		4,204
Total	$	838,241	$	829,403

Included in other securities were shares of stock in each Federal Home Loan Bank (the "FHLB") of Des Moines, Dallas and Topeka at an amortized cost of $25.8 million at December 31, 2023 and $12.3 million at December 31, 2022.

HTLF Bank is required to maintain FHLB stock as a member of the FHLB. These equity securities are "restricted" in that they can only be sold back to the respective institutions or another member institution at par. Therefore, they are less liquid than other marketable equity securities and their fair value approximates amortized cost. HTLF considers its FHLB stock as a long-term investment that provides access to competitive products and liquidity. HTLF evaluates impairment in these investments based on the ultimate recoverability of the par value and at December 31, 2023, did not consider the investments to be other than temporarily impaired.

As of December 31, 2023, HTLF had $65.4 million compared to $49.1 million as of December 31, 2022, of accrued interest receivable, which is included in other assets on the consolidated balance sheets. HTLF does not consider accrued interest receivable in the allowance for credit losses calculation.

The following table shows the balance in the allowance for credit losses at December 31, 2023, and December 31, 2022, and the related loan balances, disaggregated on the basis of measurement methodology, in thousands. If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and are on nonaccrual are individually assessed using a collateral dependency calculation. All other loans are collectively evaluated for losses.

HTLF's internal rating system is a series of grades reflecting management's risk assessment, based on its analysis of the borrower's financial condition. The "pass" category consists of all loans that are not in the "nonpass" category and categorized into a range of loan grades that reflect increasing, though still acceptable risk. Movement of risk through the various grade levels in the pass category is monitored for early identification of credit deterioration.

The "nonpass" category consists of watch, substandard, doubtful and loss loans. The "watch" rating is attached to loans where the borrower exhibits negative trends in financial circumstances due to borrower specific or systemic conditions that, if left uncorrected, threaten the borrower's capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. These credits are closely monitored for improvement or deterioration.

The "substandard" rating is assigned to loans that are inadequately protected by the current net worth and repaying capacity of the borrower and that may be further at risk due to deterioration in the value of collateral pledged. Well-defined weaknesses jeopardize liquidation of the debt. These loans are still considered collectible; however, a distinct possibility exists that HTLF will sustain some loss if deficiencies are not corrected. Substandard loans may exhibit some or all the following weaknesses: deteriorating financial trends, lack of earnings, inadequate debt service capacity, excessive debt and/or lack of liquidity.

The "doubtful" rating is assigned to loans where identified weaknesses in the borrowers' ability to repay the loan make collection or liquidation in full, based on existing facts, conditions and values, highly questionable and improbable. These borrowers are usually in default, lack liquidity and capital, as well as resources necessary to remain as an operating entity. Specific pending events, such as capital injections, liquidations or perfection of liens on additional collateral, may strengthen the credit, thus deferring the rating of the loan as "loss" until the exact status of the loan can be determined. The loss rating is assigned to loans considered uncollectible. As of December 31, 2023, and December 31, 2022, HTLF had no loans classified as doubtful and no loans classified as loss.

GOODWILL, CORE DEPOSIT INTANGIBLES AND OTHER INTANGIBLE ASSETS

GOODWILL, CORE DEPOSIT INTANGIBLES AND OTHER INTANGIBLE ASSETS

HTLF had goodwill of $576.0 million at both December 31, 2023, and December 31, 2022. HTLF conducts its annual internal assessment of the goodwill both at the consolidated level and at the reporting unit level as of September 30. However, due the sustained decline in HTLF's stock price, which management considered a triggering event, HTLF performed an interim quantitative goodwill assessment during the second quarter of 2023, and there was no goodwill impairment identified. HTLF also conducted its annual internal assessment of the goodwill at HTLF or HTLF's reporting units as of September 30. There was no goodwill impairment as of the most recent assessment.

The gross carrying amount of other intangible assets, which consisted of core deposit intangibles and mortgage servicing rights, and the associated accumulated amortization at December 31, 2023, and December 31, 2022, are presented in the table below, in thousands:

On March 31, 2023, First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing rights portfolio, which contained loans with an unpaid principal balance of $698.5 million, to two unrelated third parties. The transaction qualified as a sale, and $7.7 million of mortgage servicing rights was derecognized on the consolidated balance sheet as of March 31, 2023. Cash of approximately $6.7 million was received on March 31, 2023, and an estimated loss of $203,000 was recorded. A receivable of approximately $580,000 was recorded in other assets on the consolidated balance sheet as of March 31, 2023, due to the timing of the servicing transfer per the terms of the sale agreement. First Bank & Trust provided interim servicing of the loans until the transfer date, which was May 1, 2023.

DERIVATIVE FINANCIAL INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

DERIVATIVE FINANCIAL INSTRUMENTS

HTLF considers and uses derivative financial instruments as part of its interest rate risk management strategy, which may include interest rate swaps, fair value hedges, risk participation agreements, caps, floors, collars, and certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. HTLF's current strategy includes the use of interest rate swaps. In addition, HTLF facilitates back-to-back loan swaps to assist customers in managing their interest rate risk while executing offsetting interest rate swaps with dealer counterparties.

HTLF's objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amounts to be exchanged between the counterparties. HTLF is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. HTLF minimizes this risk by entering into derivative contracts with counterparties that meet HTLF’s credit standards, and the contracts contain collateral provisions protecting the at-risk party. HTLF has not experienced any losses from nonperformance by these counterparties. HTLF monitors counterparty risk in accordance with the provisions of ASC 815. HTLF was required to post $27.7 million of collateral at December 31, 2023, compared to $793,000 as of December 31, 2022, related to derivative financial instruments. HTLF's counterparties were required to pledge $44.8 million at December 31, 2023, compared to $45.1 million at December 31, 2022. HTLF records interest rate derivatives subject to master netting agreements at their gross value and does not offset derivative assets and liabilities on the consolidated balance sheets.

HTLF's derivative and hedging instruments are recorded at fair value on the consolidated balance sheets. See Note Eighteen, "Fair Value," for additional fair value information and disclosures.

Cash Flow Hedges

In 2021, two interest rate swap transactions were terminated, and the debt was converted to variable rate subordinated debentures. For the next twelve months, HTLF estimates cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense related to the terminated swaps will total $227,000.

In the first quarter of 2023, HTLF terminated its interest rate swap agreement, which effectively converted $500.0 million of variable rate loans to fixed rate loans. For the next twelve months, HTLF estimates cash payments and reclassification from accumulated other comprehensive income (loss) to interest expense will total $985,000.

HTLF had no derivative instruments designated as cash flow hedges at December 31, 2023. The table below identifies the balance sheet category and fair value of HTLF's derivative instrument designated as a cash flow hedge at December 31, 2022, in thousands:

For the Year Ended December 31, 2022

Fair Value Hedges

HTLF uses interest rate swaps to convert certain long term fixed rate loans to floating rates to hedge interest rate risk exposure. HTLF also uses interest rate swaps to mitigate the risk of changes in the fair market value of certain municipal and mortgage-backed securities. The changes in the fair values of derivatives that have been designated and qualify for fair value hedge accounting are recorded in the same line item in the consolidated statements of income as the changes in the fair value of the hedged items attributable to the risk being hedged.

HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in the fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

During 2023, HTLF entered into interest rate swaps designated as fair value hedges with initial notional amounts totaling $838.1 million primarily designed to provide protection for unrealized securities losses against the impact of higher mid-to-long term interest rates. HTLF also executed interest rate swaps designated as a fair value hedges with total original notional amounts of $2.5 billion to convert certain long-term fixed rate loans to floating rates to hedge interest rate risk exposure using the portfolio layer method, which allows HTLF to designate as the hedged item a stated amount of the assets that are not expected to be affected by prepayments, defaults and other factors that would affect the timing and amount of cash flow.

The table below identifies the fair value of the interest rate swaps designated as fair value hedges and the balance sheet category of the interest rate swaps at December 31, 2023, and December 31, 2022, in thousands:

Embedded Derivatives

HTLF has fixed rate loans with embedded derivatives. The loans contain terms that affect the cash flows or value of the loan similar to a derivative instrument, and therefore are considered to contain an embedded derivative. The embedded derivatives are bifurcated from the loans because the terms of the derivative instrument are not clearly and closely related to the loans. The embedded derivatives are recorded at fair value on the consolidated balance sheets as a part of other assets, and changes in the fair value are a component of noninterest income. The table below identifies the notional amount, fair value and balance sheet category of HTLF's embedded derivatives as of December 31, 2023, and December 31, 2022, in thousands:

Back-to-Back Loan Swaps

HTLF has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps, HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free-standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income, and for the years ended December 31, 2023, and December 31, 2022, no gains or losses were recognized. HTLF recognized $7.7 million in fee income for the year ended December 31, 2023, compared to $6.6 million for the year ended December 31, 2022.

The table below identifies the balance sheet category and fair values of HTLF's derivative instruments designated as loan swaps at December 31, 2023 and 2022, in thousands:

Other Free-Standing Derivatives

HTLF has entered into interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities that are considered derivative instruments. HTLF enters into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on the commitments to fund the loans as well as on residential mortgage loans available for sale. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. HTLF was required to pledge $0 at both December 31, 2023, and December 31, 2022, as collateral for these forward commitments. HTLF's counterparties were required to pledge no cash as collateral at both December 31, 2023, and December 31, 2022, as collateral for these forward commitments.

HTLF acquired undesignated interest rate swaps in 2015. These swaps were entered into primarily for the benefit of customers seeking to manage their interest rate risk and are not designated against specific assets or liabilities on the consolidated balance sheet or forecasted transactions and therefore do not qualify for hedge accounting in accordance with ASC 815. These swaps are carried at fair value on the consolidated balance sheets as a component of other liabilities, with changes in the fair value recorded as a component of other noninterest income.

INCOME TAXES

INCOME TAXES

The current income tax provision reflects the tax consequences of revenue and expenses currently taxable or deductible on various income tax returns for the year reported. The deferred income tax provision generally reflects the net change in deferred income tax assets and liabilities during the year, excluding any deferred income tax assets and liabilities of acquired businesses. The components of the provision for income taxes for the years ended December 31, 2023, 2022, and 2021 were as follows, in thousands:

	2023		2022		2021
Current:
Federal	$	18,844	$	45,911	$	32,440

Total income tax expense	$	16,857	$	55,573	$	55,335

Temporary differences between the amounts reported in the financial statements and the tax basis of assets and liabilities result in deferred taxes. Deferred tax assets and liabilities at December 31, 2023 and 2022, were as follows, in thousands:

	2023		2022

As a result of acquisitions, HTLF had net operating loss carryforwards for federal income tax purposes of approximately $14.0 million at December 31, 2023, and $17.2 million at December 31, 2022. The associated deferred tax asset was $2.9 million at December 31, 2023, and $3.6 million at December 31, 2022. These net carryforwards expire during the period from December 31, 2025, through December 31, 2035, and are subject to an annual limitation of approximately $3.1 million. Net operating loss carryforwards for state income tax purposes were approximately $191.9 million at December 31, 2023, and $203.4 million at December 31, 2022. The associated deferred tax asset, net of federal tax, was $9.9 million at December 31, 2023, and $16.3 million at December 31, 2022. These carryforwards have begun to expire and will continue to do so until December 31, 2031.

A valuation allowance against the deferred tax asset due to the uncertainty surrounding the utilization of these state net operating loss carryforwards was $9.4 million at December 31, 2023, and $15.5 million at December 31, 2022. During both 2023 and 2022, HTLF had book write-downs on investments that, for tax purposes, would generate capital losses upon disposal. Due to the uncertainty of HTLF's ability to utilize the potential capital losses, a valuation allowance for these potential losses totaled $1.7 million at December 31, 2023, and $1.5 million at December 31, 2022. HTLF released valuation allowances of $0 and $165,000 in 2023 and 2022, respectively, on deferred tax assets for capital losses it expects to realize on the disposal of partnership investments.

Realization of the deferred tax asset over time is dependent upon the existence of taxable income in carryback periods or the ability to generate sufficient taxable income in future periods. In determining that realization of the deferred tax asset was more likely than not, HTLF considered a number of factors, including its taxable income during carryback periods, its recent earnings history, its expectations for earnings in the future and, where applicable, the expiration dates associated with its tax carryforwards.

The actual income tax expense from continuing operations differs from the expected amounts for the years ended December 31, 2023, 2022, and 2021, (computed by applying the U.S. federal corporate tax rate of 21% for 2023, 2022, and 2021 income before income taxes) are as follows, in thousands:

HTLF's income taxes included solar energy tax credits totaling $4.2 million, $4.2 million, and $6.1 million during 2023, 2022 and 2021, respectively. Federal historic rehabilitation tax credits included in HTLF's income taxes totaled $1.1 million, $1.0 million, and $720,000 in 2023, 2022, and 2021, respectively. Additionally, investments in certain low-income housing partnerships totaled $9.3 million at December 31, 2023, $10.4 million at December 31, 2022, and $5.1 million at December 31, 2021. These investments generated federal low-income housing tax credits of $1.2 million during 2023, $1.1 million at December 31, 2022, and $538,000 at December 31, 2021. These investments are expected to generate federal low-income housing tax credits of approximately $1.0 million for 2024, $790,000 for 2025, $740,000 for 2026 and $705,000 for 2027. Additionally, HTLF had new markets tax credits of $360,000 and $300,000 in 2023 and 2022, respectively.

On December 31, 2023, the amount of unrecognized tax benefits was $709,000, including $129,000 of accrued interest and penalties. On December 31, 2022, the amount of unrecognized tax benefits was $719,000, including $91,000 of accrued interest and penalties. If recognized, the entire amount of the unrecognized tax benefits would affect the effective tax rate.

The tax years ended December 31, 2020, and later remain subject to examination by the Internal Revenue Service. For state purposes, the tax years ended December 31, 2018, and later remain open for examination. HTLF does not anticipate any significant increase or decrease in unrecognized tax benefits during the next twelve months.

EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS

HTLF sponsors a defined contribution retirement plan covering substantially all employees. The plan includes matching contributions and non-elective contributions. Matching contributions and non-elective contributions are limited to a maximum amount of the participant's wages as defined by federal law.

HTLF's subsidiaries made matching contributions of up to 5% of participants' wages in 2023 and 3% of participants' wages in 2022 and 2021. Costs charged to operating expenses with respect to the matching contributions were $7.9 million, $5.3 million, and $5.1 million for 2023, 2022 and 2021, respectively.

Non-elective contributions to this plan are subject to approval by the HTLF Board of Directors. The HTLF subsidiaries fund and record as an expense all approved contributions. Costs of these contributions, charged to operating expenses, were $3.1 million, $5.8 million, and $5.1 million for 2023, 2022 and 2021, respectively.

In addition, HTLF has a non-qualified defined contribution plan that allows eligible employees to make voluntary contributions into a deferred compensation plan. Any non-elective contributions to this plan are subject to approval by the HTLF Board of Directors. For the years ended December 31, 2023, 2022 and 2021, the employer contributions to the non-qualified defined contribution plan were $235,000, $222,500 and $237,200, respectively, and are included in the matching contributions and non-elective contributions amounts noted above.

Commitments and Contingencies Disclosure [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

COMMITMENTS AND CONTINGENT LIABILITIES

HTLF utilizes a variety of financial instruments in the normal course of business to meet the financial needs of customers and to manage its exposure to fluctuations in interest rates. These financial instruments include lending related and other commitments as indicated below as well as derivative instruments shown in Note Eleven, "Derivative Financial Instruments." HTLF Bank makes various commitments and incurs certain contingent liabilities that are not presented in the accompanying consolidated financial statements. The commitments and contingent liabilities include various guarantees, commitments to extend credit and standby letters of credit.

Commitments to extend credit are agreements to lend to a customer if there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. HTLF Bank evaluates the creditworthiness of customers to which they extend a credit commitment on a case-by-case basis and may require collateral to secure any credit extended. The amount of collateral obtained is based upon management's credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment and income-producing commercial properties. Standby letters of credit and financial guarantees are conditional commitments issued by HTLF Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. At December 31, 2023, and at December 31, 2022, commitments to extend credit aggregated $4.62 billion and $4.73 billion, respectively, and standby letters of credit aggregated $56.4 million and $55.1 million, respectively.

Previously, HTLF entered into commitments to sell mortgage loans to reduce interest rate risk on certain mortgage loans held for sale and loan commitments, which were recorded in the consolidated balance sheets at their fair values. HTLF does not anticipate any material loss as a result of the commitments and contingent liabilities. Residential mortgage loans sold to others were predominantly conventional residential first lien mortgages originated under HTLF's usual underwriting procedures and were most often sold on a nonrecourse basis. HTLF's agreements to sell residential mortgage loans in the normal course of business, primarily to GSE's, which usually required certain representations and warranties on the underlying loans sold, related to credit information, loan documentation, collateral, and insurability, which if subsequently are untrue or breached, could require HTLF to repurchase certain loans affected. HTLF had no repurchase obligation at both December 31, 2023 and December 31, 2022. HTLF had no new requests for repurchases during 2023 and 2022.

There are certain legal proceedings pending against HTLF and its subsidiaries at December 31, 2023, that are ordinary routine litigation incidental to business. While the ultimate outcome of current legal proceedings cannot be predicted with certainty, it is the opinion of management that the resolution of these legal actions should not have a material effect on HTLF's consolidated financial position or results of operation.

STOCK-BASED COMPENSATION

Share-Based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

HTLF may grant, through its Compensation and Human Capital Committee (the "Compensation Committee") non-qualified and incentive stock options, stock appreciation rights, stock awards, restricted stock, restricted stock units and cash incentive awards, under its 2020 Long-Term Incentive Plan (the "Plan") which authorized 1,460,000 of common stock available for issuance. At December 31, 2023, 744,310 shares of common stock were reserved for future issuance under awards that may be granted under the Plan to employees and directors of, and service providers to, HTLF or its subsidiaries.

ASC Topic 718, "Compensation-Stock Compensation" requires the measurement of the cost of employee services received in exchange for an award of equity instruments based upon the fair value of the award on the grant date. The cost of the award is based upon its fair value estimated on the date of grant and recognized in the consolidated statements of income over the vesting period of the award. The fair market value of restricted stock and restricted stock units is based on the fair value of the underlying shares of common stock on the date of grant. Forfeitures are accounted for as they occur.

HTLF's income tax expense included $123,000 of expense and $131,000 of benefit for the years ended December 31, 2023, and December 31, 2022, respectively, related to the vesting and forfeiture of equity-based awards.

Restricted Stock Units

The Plan permits the Compensation Committee to grant restricted stock units ("RSUs"). The time-based RSUs represent the right, without payment, to receive shares of HTLF common stock at a specified date in the future. Generally, the time-based RSUs vest over three years in equal installments in March of each of the three years following the year of the grant.

The Compensation Committee has granted three-year performance-based RSUs. These performance-based RSUs will be earned based upon satisfaction of performance targets for the three-year performance period, which is defined in the RSU agreement. These performance-based RSUs or a portion thereof may vest after measurement of performance in relation to the performance targets.

The time-based RSUs may also vest upon death or disability, upon a change in control or upon a "qualified retirement" (as defined in the RSU agreement), and the three-year performance-based RSUs vest to the extent that they are earned upon death or disability or upon a "qualified retirement" (as defined in the RSU agreement) after measurement of performance.

All of HTLF's RSUs will be settled in common stock upon vesting. Most RSUs granted after March 2023 accrue dividends, which are paid without interest only upon vesting. Dividend equivalents with respect to RSUs forfeited are also forfeited. RSUs granted prior to 2023 are not entitled to dividend equivalents.

A summary of the status of RSUs as of December 31, 2023, 2022 and 2021, and changes during the years ended December 31, 2023, 2022, and 2021, follows:

	2023			2022			2021

Outstanding at December 31	466,105	$	47.22	424,086	$	46.15	389,885	$	44.19

Total compensation costs recorded for RSUs were $9.0 million, $7.8 million and $8.5 million, for 2023, 2022 and 2021, respectively. As of December 31, 2023, there were $8.8 million of total unrecognized compensation costs related to the Plan for RSUs which are expected to be recognized through 2026.

Stock Options

The plan provides the Compensation Committee the authority to grant stock options. During the year ended December 31, 2023, 0 options were granted. There were 64,518 options granted in the year ended December 31, 2022, and no options granted in the year ended December 31, 2021. Options granted generally vest over the first four years in equal installments on the anniversary date of the grant. The exercise price of the stock options granted is established by the Compensation Committee, but the exercise price may not be less than the fair market value of the shares on the date the options are granted.

The stock options may also vest upon death or disability, upon a change in control or upon a "qualified retirement" as defined in the stock option agreement.

A summary of the status of the stock options as of December 31, 2023, 2022, and 2021, and changes during the years ended December 31, 2023, 2022, and 2021 follows:

	2023			2022			2021

At December 31, 2023, the vested options have a weighted average remaining contractual life of 8.92 years. The intrinsic value for the vested options as of December 31, 2023, was $0. The intrinsic value for the total of all options exercised during year ended December 31, 2023, was $0. The total fair value of shares under stock options that vested during the year ended December 31, 2023, was $0. Total compensation costs recorded for stock options were $221,000, $167,000, and $0 for 2023, 2022, and 2021, respectively. As of December 31, 2023, there was $490,000 of total unrecognized compensation costs related to the Plan for options that are expected to be recognized through 2026.

Employee Stock Purchase Plan

HTLF maintains an employee stock purchase plan (the "ESPP"), which was adopted in May 2016 and replaced the 2006 ESPP, that permits all eligible employees to purchase shares of HTLF common stock at a discounted price as determined by the Compensation Committee. Under ASC Topic 718, compensation expense related to the ESPP of $192,000 was recorded in 2023, $214,000 was recorded in 2022, and $228,000 was recorded in 2021.

A maximum of 500,000 shares is available for purchase under the ESPP, and as of December 31, 2023, 171,537 shares remain available for purchase. Beginning with the 2020 plan year, the Compensation Committee authorized HTLF to make ESPP purchases semi-annually, and the purchases are to be made as soon as practicable on or after June 30 and December 31. For employee deferrals made in the 2023 plan year, shares purchased in 2023 totaled 60,583. For employee deferrals made in the 2022 plan year, shares purchased in 2022 totaled 49,169. For employee deferrals made in the 2021 plan year, shares purchased in 2021 totaled 46,899.

REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS ON SUBSIDIARY DIVIDENDS

Federal Home Loan Banks [Abstract]

REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS ON SUBSIDIARY DIVIDENDS

REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS ON SUBSIDIARY DIVIDENDS

HTLF Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that,

if undertaken, could have a direct material effect on HTLF Bank's financial statements. The regulations prescribe specific capital adequacy guidelines that involve quantitative measures of a bank’s assets, liabilities and certain off balance sheet items as calculated under regulatory accounting practices. Capital classification is also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require HTLF Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital (as defined) to average assets (as defined).

The requirements to be categorized as well-capitalized under the Tier 1 leverage capital ratio is 4% for all banks. The minimum requirement to be well-capitalized for the Tier 1 risk-based capital ratio is 8%. The total risk-based capital ratio minimum requirement to be well-capitalized remained is 10%. Management believes, as of December 31, 2023 and 2022, that HTLF Bank met all capital adequacy requirements to which it was subject.

As of December 31, 2023 and 2022, the FDIC categorized HTLF Bank, and all HTLF member banks prior to charter consolidation, as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Banks must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 common equity and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since December 31, 2023, that management believes have changed each institution’s category.

HTLF Bank's, and all HTLF member banks prior to charter consolidation, actual capital amounts and ratios are also presented in the tables below, in thousands:

Fair Value Disclosures [Abstract]

FAIR VALUE

FAIR VALUE

HTLF utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities carried at fair value, which include available for sale, trading securities and equity securities with a readily determinable fair value, and derivatives are recorded in the consolidated balance sheets at fair value on a recurring basis. Additionally, from time to time, HTLF may be required to record at fair value other assets on a nonrecurring basis such as loans held for sale, loans held to maturity and certain other assets including, but not limited to, mortgage servicing rights and other real estate owned. These nonrecurring fair value adjustments typically involve application of lower of cost or fair value accounting or write-downs of individual assets.

Fair Value Hierarchy

Under ASC 820, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring or non-recurring basis.

Assets

Securities Available for Sale and Held to Maturity

Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are generally recorded at cost. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities. Level 2 securities include U.S. government and agency securities, mortgage and asset-backed securities and private collateralized mortgage obligations, municipal bonds, equity securities and corporate debt securities. On a quarterly basis, a secondary independent pricing service is used for the securities portfolio to validate the pricing from HTLF's primary pricing service.

Equity Securities with a Readily Determinable Fair Value

Equity securities with a readily determinable fair value generally include Community Reinvestment Act mutual funds and are classified as Level 2 due to the infrequent trading of these securities. The fair value is based on the price per share.

Loans Held for Sale

Loans held for sale are carried at the lower of cost or fair value on an aggregate basis. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, HTLF classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2.

Loans Held to Maturity

HTLF does not record loans held to maturity at fair value on a recurring basis. However, from time to time, certain loans are considered collateral dependent and an allowance for credit losses is established. The fair value of individually assessed loans is measured using the fair value of the collateral. In accordance with ASC 820, individually assessed loans measured at fair value are classified as nonrecurring Level 3 in the fair value hierarchy.

Premises, Furniture and Equipment Held for Sale

HTLF values premises, furniture and equipment held for sale based on third-party appraisals less estimated disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in

selling bank premises, furniture and equipment, in determining the fair value of particular properties. Accordingly, the valuation of premises, furniture and equipment held for sale is subject to significant external and internal judgment. HTLF periodically reviews premises, furniture and equipment held for sale to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. Premises, furniture and equipment held for sale are measured at fair value and are classified as nonrecurring Level 3 in the fair value hierarchy.

Mortgage Servicing Rights

Mortgage servicing rights assets represent the value associated with servicing residential real estate loans that have been sold to outside investors with servicing retained. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds and delinquency rate assumptions as inputs. All these assumptions require a significant degree of management estimation and judgment. Mortgage servicing rights are subject to impairment testing. The carrying values of these rights are reviewed quarterly for impairment based upon the calculation of fair value as performed by an outside third-party. For purposes of measuring impairment, the rights are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance. HTLF classifies mortgage servicing rights as nonrecurring with Level 3 measurement inputs.

On March 31, 2023, HTLF sold its mortgage servicing rights portfolio. The transaction qualified as a sale, and $7.7 million of mortgage servicing rights were derecognized on the consolidated balance sheet as of March 31, 2023. The book value and fair value were both $0 as of March 31, 2023.

Derivative Financial Instruments

HTLF's current interest rate risk strategy includes cash flow hedges and interest rate swaps. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. To comply with the provisions of ASC 820, HTLF incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, HTLF has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although HTLF has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2023, and December 31, 2022, HTLF has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, HTLF has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

Interest Rate Lock Commitments

HTLF uses an internal valuation model that relies on internally developed inputs to estimate the fair value of its interest rate lock commitments which is based on unobservable inputs that reflect management's assumptions and specific information about each borrower. Interest rate lock commitments are classified in Level 3 of the fair value hierarchy.

Forward Commitments

The fair value of forward commitments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments in active markets that HTLF has the ability to access and are classified in Level 2 of the fair value hierarchy.

Other Real Estate Owned

Other real estate owned ("OREO") represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the fair value of the property at the time of acquisition (representing the property's cost basis), plus any acquisition costs, or the estimated fair value of the property, less disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in selling OREO, in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. HTLF periodically reviews OREO to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. OREO is classified as nonrecurring Level 3 of the fair value hierarchy.

The tables below present HTLF's assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2023, and December 31, 2022, in thousands, aggregated by the level in the fair value hierarchy within which those measurements fall:

(1) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(2) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.

(1) The significant unobservable input used in the fair value measurement is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio calculation takes into consideration historical data and loan-level data.
(2) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(3) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.
(4) The significant unobservable inputs used in the discounted cash flow analysis are the discount rate and constant prepayment rate.

The changes in fair value of the interest rate lock commitments, which are Level 3 financial instruments and are measured on a recurring basis, are summarized in the following table, in thousands:

	For the Years Ended
	December 31, 2023		December 31, 2022
Balance at January 1,	$	174	$	1,306
Total gains (losses), net, included in earnings	(290)		(1,828)
Issuances	1,864		3,683
Settlements	(1,748)		(2,987)
Balance at period end	$	—	$	174

Gains included in net gains on sale of loans held for sale attributable to interest rate lock commitments held at December 31, 2023, and December 31, 2022, were $0 and $174,000, respectively.

The table below is a summary of the estimated fair value of HTLF's financial instruments (as defined by ASC 825) as of December 31, 2023, and December 31, 2022, in thousands. The carrying amounts in the following table are recorded in the consolidated balance sheets under the indicated captions. In accordance with ASC 825, the assets and liabilities that are not financial instruments are not included in the disclosure, including the value of the commercial and mortgage servicing rights, premises, furniture and equipment, premises, furniture and equipment held for sale, OREO, goodwill, other intangibles and other liabilities.

HTLF does not believe that the estimated information presented below is representative of the earnings power or value of HTLF. The following analysis, which is inherently limited in depicting fair value, also does not consider any value associated with either existing customer relationships or the ability of HTLF to create value through loan origination, obtaining deposits or fee generating activities. Many of the estimates presented below are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.

Cash and Cash Equivalents — The carrying amount is a reasonable estimate of fair value due to the short-term nature of these instruments.

Time Deposits in Other Financial Institutions — The carrying amount is a reasonable estimate of the fair value due to the short-term nature of these instruments.

Securities — For equity securities with a readily determinable fair value and debt securities either held to maturity, available for

sale or trading, fair value equals quoted market price if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. For Level 3 securities, HTLF utilizes independent pricing provided by third-party vendors or brokers.

Other Investments — Fair value measurement of other investments, which consists primarily of FHLB stock, are based on their redeemable value, which is at cost. The market for these securities is restricted to the issuer of the stock and subject to impairment evaluation.

Loans — The fair value of loans were determined using an exit price methodology. The exit price estimation of fair value is based on the present value of the expected cash flows. The projected cash flows are based on the contractual terms of the loans, adjusted for prepayments and a discount rate based on the relative risk of the cash flows. Other considerations include the loan type, the remaining life of the loan and credit risk.

The fair value of individually assessed or impaired loans is measured using the fair value of the underlying collateral. The fair value of loans held for sale is estimated using quoted market prices or sales contracts.

Cash surrender value on life insurance — Life insurance policies are held on certain officers. The carrying value of these policies approximates fair value as it is based on the cash surrender value adjusted for other charges or amounts due that are probable at settlement. As such, HTLF classifies the estimated fair value of the cash surrender value on life insurance as Level 2.

Derivative Financial Instruments — The fair value of all derivatives is estimated based on the amount that HTLF would pay or would be paid to terminate the contract or agreement, using current rates, and when appropriate, the current creditworthiness of the counterparty.

Interest Rate Lock Commitments — The fair value of interest rate lock commitments is estimated using an internal valuation model, which includes grouping the interest rate lock commitments by interest rate and terms, applying an estimated closing ratio based on historical experience, and then multiplying by quoted investor prices determined to be reasonably applicable to the loan commitment groups based on interest rate, terms, and rate lock expiration dates of the loan commitment group.

Forward Commitments — The fair value of these instruments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments.

Deposits — The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities. If the fair value of the fixed maturity certificates of deposit is calculated at less than the carrying amount, the carrying value of these deposits is reported as the fair value.

Borrowings and Term Debt — Rates currently available to HTLF for debt with similar terms and remaining maturities are used to estimate fair value of existing debt.

Commitments to Extend Credit, Unused Lines of Credit and Standby Letters of Credit — Based upon management's analysis of the off balance sheet financial instruments, there are no significant unrealized gains or losses associated with these financial instruments based upon review of the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties.

Revenue from Contract with Customer [Abstract]

REVENUE

REVENUE

ASC 606, Revenue from Contracts with Customers, requires revenue to be recognized at an amount that reflects the consideration to which HTLF expects to be entitled in exchange for transferring goods or services to a customer. ASC 606 applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of HTLF's revenue streams including interest income, loan servicing income, net securities gain and losses, net unrealized gains and losses on equity securities, net gains on sale of loans held for sale, valuation adjustment on servicing rights, income from bank owned life insurance and other noninterest income are outside the scope of ASC 606. Revenue streams including service charges and fees, interchange fees on credit and debit cards, trust fees and brokerage and insurance commissions are within the scope of ASC 606.

Service Charges and Fees

Service charges and fees consist of revenue generated from deposit account related service charges and fees, overdraft fees, customer service fees and other service charges, credit card fee income, debit card income and other service charges and fees.

Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders and other deposit account related fees. HTLF's performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees, including overdraft fees, are largely transaction based, and therefore, the performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Customer service fees and other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. HTLF's performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.

Credit card fee income and debit card income are comprised of interchange fees, ATM fees, and merchant services income. Credit card fee income and debit card income are earned whenever HTLF Bank's debit and credit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Bank cardholder uses an ATM that is not owned by one of HTLF's Banks or a non-bank cardholder uses HTLF-owned ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees.

Trust Fees

Trust fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. HTLF's performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the average daily market value or month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days before or after month end through a direct charge to customers’ accounts. HTLF does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. HTLF's performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Brokerage and Insurance Commissions

Brokerage commission primarily consists of commissions related to broker-dealer contracts. The contracts are between the customer and the broker-dealer, and HTLF satisfies its performance obligation and earns commission when the transactions are completed. The recognition of revenue is based on a defined fee schedule and does not require significant judgment. Payment is received shortly after services are rendered. Insurance commissions are related to commissions received directly from the insurance carrier. HTLF acts as an insurance agent between the customer and the insurance carrier. HTLF's performance obligations and associated fee and commission income are defined with each insurance product with the insurance company. When insurance payments are received from customers, a portion of the payment is recognized as commission revenue.

The following presents noninterest income, segregated by revenue streams in-scope and out-of-scope of Topic 606, for the year ended December 31, 2023, 2022, and 2021, in thousands:

Contract Balances

HTLF does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2023, 2022, and 2021, HTLF did not have any significant contract balances or capitalized contract acquisition costs.

Leases [Abstract]

LEASES

LEASES

HTLF, as lessee, leases certain assets for use in its operations. Leased assets primarily include real estate property for retail branches, ATM locations and operations centers with terms extending through 2031. All HTLF's leases are classified as operating leases. HTLF excludes leases with an original term of twelve months or less and equipment leases (deemed immaterial) on the consolidated balance sheets. HTLF leases some of its facilities to third parties and receives rental income from such lease agreements which is not significant.

The table below presents HTLF's right-of-use ("ROU") assets and lease liabilities as of December 31, 2023 and December 31, 2022, in thousands:

		As of December 31,
	Classification	2023		2022
Operating lease right-of-use assets	Other assets	$	25,859	$	29,429
Operating lease liabilities	Accrued expenses and other liabilities	$	29,333	$	31,681

The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. HTLF’s lease agreements often include one or more options to renew at HTLF’s discretion. If at lease inception, HTLF considers the exercising of a renewal option to be reasonably certain, HTLF will include the extended term in the calculation of the ROU asset and lease liability. HTLF utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. The variable lease cost primarily represents variable payments such as common area maintenance and utilities.

The table below presents the lease costs and supplemental information as of December 31, 2023, 2022, and 2021, in thousands:

	Income Statement Category	As of December 31,
Lease Cost		2023		2022		2021

Included in the noncash reduction of ROU assets in 2023 and 2022 are expenses related to lease modifications and ROU acceleration related to lease abandonments.

HTLF recorded $63,000 of impairment on one lease in 2023, which was recorded in gain (loss) on sales/valuations of assets, net. HTLF recorded $360,000 of impairment on two leases in 2022, and no impairment on leases in 2021.

During the second quarter of 2023, HTLF reclassified Federal Deposit Insurance Corporation ("FDIC") insurance premiums to FDIC insurance assessments from professional fees on the consolidated statements of income, and all prior periods have been adjusted.

In the second quarter of 2023, HTLF amended and restated its Certificate of Incorporation and filed Certificates of Elimination with the state of Delaware with respect to Series A, B, C, and D preferred stock issuances, which returned these previously designated shares to authorized but unissued. The following shows the details of Series A, B, C and D preferred stock at December 31, 2022:

The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and prevailing practices within the banking industry. In preparing such financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheets and revenues and expenses for the years then ended. Actual results could differ significantly from those estimates. A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for credit losses.

Business Combinations

Business Combinations - HTLF applies the acquisition method of accounting in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 805, Business Combinations. Under the acquisition method, HTLF recognizes assets acquired, including identified intangible assets, and the liabilities assumed in acquisitions at fair value as of the acquisition date, with the acquisition-related transaction costs expensed in the period incurred. Determining the fair value of assets acquired and liabilities assumed often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques that may include estimates of attrition, inflation, asset growth rates, discount rates, multiples of earnings or other relevant factors. In addition, the determination of the useful lives over which an intangible asset will be amortized is subjective.

Cash and Cash Equivalents

Cash and Cash Equivalents - For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest bearing deposits held at the Federal Reserve Bank, federal funds sold to other banks and other short-term investments. Generally, federal funds are purchased and sold for one-day periods.

Trading Securities, Available for Sale Debt Securities and Equity Securities, Allowance for Credit Losses on AFS Debt Securities, Securities, Securities Held to Maturity, and Allowance for Credit Losses on Held to Maturity Debt Securities

Trading Securities - Trading securities represent those securities HTLF intends to actively trade and are stated at fair value with changes in fair value reflected in noninterest income. HTLF had no trading securities at both December 31, 2023 and 2022.

Available for Sale ("AFS") Debt Securities and Equity Securities - Available for sale securities consist of those securities not classified as held to maturity or trading, which management intends to hold for indefinite periods of time or that may be sold in response to changes in interest rates, prepayments or other similar factors. Available for sale securities are stated at fair value with any unrealized gain or loss, net of applicable income tax, reported as a separate component of stockholders’ equity. Security premiums and discounts are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, the financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, regarding debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

Realized securities gains or losses on securities sales (using a specific identification method) are included in securities gains, net in the consolidated statements of income.

Equity securities include Community Reinvestment Act funds with readily determinable fair values and are carried at fair value. Certain equity securities do not have readily determinable fair values, such as Federal Reserve Bank stock and Federal Home Loan Bank stock, which are held for debt and regulatory purposes and are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. HTLF did not record any impairment or other adjustments to the carrying amount of these investments during the years ended December 31, 2023, and December 31, 2022.

Allowance for Credit Losses on AFS Debt Securities - HTLF reviews the investment securities portfolio at the security level on a quarterly basis for potential credit losses, which takes into consideration numerous factors, and the relative significance of any single factor can vary by security. Some factors HTLF may consider include changes in security ratings, financial condition of the issuer, as well as security and industry-specific economic conditions. In addition, with regard to debt securities, HTLF may also evaluate payment structure, whether there are defaulted payments or expected defaults, prepayment speeds and the

value of any underlying collateral. For certain debt securities in unrealized loss positions, HTLF prepares cash flow analyses to compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security.

The decline in fair value of an AFS debt security due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes. Although these evaluations involve judgment, an unrealized loss in the fair value of a debt security is generally considered to not be related to credit when the fair value of the security is below the carrying value primarily due to changes in risk-free interest rates, there has not been significant deterioration in the financial condition of the issuer, and HTLF does not intend to sell nor does it believe it will be required to sell the security before the recovery of its cost basis. HTLF had no allowance for credit losses on AFS debt securities recorded at December 31, 2023, and December 31, 2022.

Securities Held to Maturity - Securities which HTLF has the ability and positive intent to hold to maturity are classified as held to maturity. Such securities are stated at amortized cost, adjusted for premiums and discounts that are amortized/accreted using the interest method over the period from the purchase date to the expected maturity or call date of the related security.

Allowance for Credit Losses on Held to Maturity Debt Securities - HTLF measures expected credit losses on held to maturity debt securities on a collective basis based on security type. The estimate of expected credit losses considers historical credit information that is adjusted for current conditions and supportable forecasts. HTLF's held to maturity debt securities consist primarily of investment grade obligations of states and political subdivisions. The forecast and forecast period used in the calculation of the allowance for credit losses for loans is used in calculating the allowance for credit losses on held to maturity debt securities. HTLF had no allowance for credit losses on held to maturity debt securities recorded at both December 31, 2023, and December 31, 2022.

Loans Held to Maturity, Acquired Loans, Allowance for Credit Losses for Loans, Loans Held for Sale, Other Real Estate

Loans Held to Maturity - Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount outstanding, net of cumulative charge-offs, unamortized net deferred loan origination fees and costs and unamortized premiums or discounts on purchased loans. HTLF has a loan policy which establishes the credit risk appetite, lending standards and underwriting criteria designed so that HTLF may extend credit in a prudent and sound manner. The HTLF loan policy is reviewed and approved on a regular basis. A reporting system supplements the review process by providing management and the board with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and nonperforming loans and potential problem loans.

HTLF originates commercial and industrial loans and owner occupied commercial real estate loans for a wide variety of business purposes, including lines of credit for capital and operating purposes and term loans for real estate and equipment purchases. Non-owner occupied commercial real estate loans provide financing for various non-owner occupied or income producing properties. Real estate construction loans are generally short-term or interim loans that provide financing for acquiring or developing commercial income properties, multi-family projects or single-family residential homes. Agricultural and agricultural real estate loans provide financing for capital improvements and farm operations, as well as livestock and machinery purchases. Residential real estate loans are originated for the purchase or refinancing of single-family residential properties. Consumer loans include loans for motor vehicles, home improvement, home equity and personal lines of credit.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. HTLF’s policy is to discontinue the accrual of interest income on any loan when, in the opinion of management, there is a reasonable doubt as to the timely collection of the interest and principal, normally when a loan is 90 days past due. When interest accruals are deemed uncollectible, interest credited to income in the current year is reversed and interest accrued in prior years is charged to the allowance for credit losses. A loan can be restored to accrual status if the borrower has resumed paying the full amount of the scheduled contractual interest and principal payments on the loan, and (1) all principal and interest amounts contractually due (including arrearages) are reasonably assured of repayment within a reasonable period of time, and (2) there is a sustained period of repayment performance (generally a minimum of six months) by the borrower in accordance with the scheduled contractual terms.

Allowance for Credit Losses for Loans - The allowance for credit losses is a valuation account that is deducted from the loans held to maturity amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged-off against the allowance when management believes the loan balance is deemed to be uncollectible. Provisions for credit losses for loans and recoveries on loans previously charged-off by HTLF are added back to the allowance.

HTLF's allowance model is designed to consider the current contractual term of the loan, defined as starting as of the most recent renewal date and ending at maturity date.

Management's estimation of expected credit losses is based on relevant information about past events, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts, including expected defaults and prepayments. Historical loss experience is generally the starting point for estimating expected credit losses. Adjustments are made to historical loss experience to reflect differences in asset-specific risk characteristics, such as underwriting standards, portfolio mix or asset terms and differences in economic conditions, both current conditions and reasonable and supportable forecasts. If HTLF is not able to make or obtain reasonable and supportable forecasts for the entire life of the financial asset, it is required to estimate expected credit losses for the remaining life using an approach that reverts to historical credit loss information. The components of the allowance for credit losses are described more specifically below.

Quantitative Factors

The quantitative component of the allowance for credit losses is measured using historical loss experience using a look back period, currently over the most recent 16 years, on a pool basis for loans with similar risk characteristics. HTLF utilizes third-party software to calculate the expected credit losses using two separate methodologies. For certain commercial and agricultural loans, the expected credit losses are calculated through a transition matrix model derived probability of default and loss given default methodology. The transition matrix model determines the life of loan probability of default using the historical transitions of loans between risk ratings and through default. The probability of default and loss given default methodology has been developed using HTLF’s historical loss experience over the look back period. For smaller commercial and agricultural loans, residential real estate loans and consumer loans, a lifetime average historical loss rate is established for each pool of loans based upon an average loss rate calculated using HTLF historical loss experience over the look back period.

The risks in the commercial and industrial loan portfolio include the unpredictability of the cash flow of the borrowers and the variability in the value of the collateral securing the loans. Owner occupied commercial real estate loans depend upon the cash flow of the borrowers and the collateral value of the real estate. Non-owner occupied commercial real estate loans typically depend, in large part, on sufficient income from the properties securing the loans to cover the operating expenses and debt service. Real estate construction loans involve additional risks because funds are advanced based upon estimates of costs and the estimated value of the completed project. Additionally, real estate construction loans have a greater risk of default in a weaker economy because the source of repayment relies on the successful and timely completion of the project. Agricultural and agricultural real estate loans depend upon the profitable operation or management of the farm property securing the loan. Loans secured by farm equipment, livestock or crops may not provide an adequate source of repayment because of damage or depreciation. Residential real estate loans depend upon the borrower's ability to repay the loan and the underlying collateral value. Consumer loans depend upon the borrower's personal financial circumstances and continued financial stability.

If a loan no longer shares similar risk characteristics with other loans in the pool, it is evaluated on an individual basis and is not included in the collective evaluation. Lending relationships with $500,000 or more of total exposure and on nonaccrual status are individually assessed using a collateral dependency calculation. A loan is collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. The impairment will be recognized by creating a specific reserve against the loan with a corresponding charge to provision expense. In most cases, the specific reserve will be charged off in the same quarter the loss is probable. In some cases, when HTLF believes certain loans do not share the same risk characteristics with other loans in the pool, the standard allows for these loans to be individually assessed. All individually assessed loan calculations are completed at least semi-annually.

Qualitative Factors

HTLF's allowance methodology also has a qualitative component, the purpose of which is to provide management with a means to take into consideration changes in current conditions that could potentially have an effect on the level of recognized loan losses, that otherwise fail to show up in the quantitative analysis performed in determining its base loan loss rates.

HTLF utilizes the following qualitative factors:

•changes in lending policies and procedures

•changes in the nature of loans

•experience and ability of management

•changes in the credit quality of the loan portfolio

•risk in acquired portfolios

•concentrations of credit

The qualitative factors for changes in lending policies and procedures, management and acquired portfolios are weighted as one factor. The other qualitative factors noted above are equally weighted as individual factors.

The qualitative adjustments are based on the comparison of the current condition to the average condition over the look back period. The adjustment amount can be either positive or negative depending on whether the current condition is better or worse than the historical average. HTLF incorporates the adjustments for changes in current conditions using an overlay approach. The adjustments are applied as a percentage adjustment in addition to the calculated historical loss rates of each pool. These adjustments reflect the extent to which HTLF expects current conditions to differ from the conditions that existed for the period over which historical information was evaluated. HTLF utilizes an anchoring approach to determine the minimum and maximum amount of qualitative allowance for credit losses, which is determined by comparing the highest and lowest historical rate to the current quantitative allowance rate to calculate the rate for the adjustment.

Economic Forecasting

The allowance for credit losses estimate incorporates a reasonable and supportable forecast of various macro-economic indices over the remaining life of HTLF’s assets. HTLF utilizes an overlay approach for its economic forecasting component, similar to the method utilized for the qualitative factors. The length of the reasonable and supportable forecast period is a judgmental determination based on the level to which the entity can support its forecast of economic conditions that drive its estimate of expected loss. HTLF compares forecasted macro-economic indices, such as unemployment and gross domestic product, to the economic conditions that existed over HTLF's look back period.

HTLF uses Moody's baseline economic forecast scenario, which is updated quarterly in HTLF's methodology, and considers other Moody's forecast scenarios to support the economic forecast component of the allowance for credit losses. The economic forecast reverts to the historical mean immediately at the end of the reasonable and supportable forecast period. HTLF utilized a one-year reasonable and supportable forecast period for the calculation of the December 31, 2023, and December 31, 2022, allowance for credit losses.

It is expected that actual economic conditions will, in many cases, differ from forecasts because the ultimate outcomes during the forecast period may be affected by events that were unforeseen, such as economic disruption and fiscal or monetary policy actions, which are exacerbated by longer forecasting periods. This uncertainty would be relevant to the entity’s confidence level as to the outcomes being forecasted. That is, an entity is likely less confident in the ultimate outcome of events that will occur at the end of the forecast period as compared to the beginning. As a result, actual future economic conditions may not be an effective indicator of the quality of management’s forecasting process, including the length of the forecast period.

Loans Held for Sale - Loans held for sale are stated at the lower of cost or fair value on an aggregate basis. Gains or losses on sales are recorded in noninterest income. Direct loan origination costs and fees are deferred at origination of the loan. These deferred costs and fees are recognized in noninterest income as part of the gain or loss on sales of loans upon sale of the loan.

At December 31, 2023 and 2022, loans held for sale primarily consisted of 1-4 family residential mortgages.

Other Real Estate - Other real estate represents property acquired through foreclosures and settlements of loans. Property acquired is recorded at the estimated fair value of the property less disposal costs. The excess of carrying value over fair value less disposal costs is charged against the allowance for credit losses. Subsequent write downs estimated on the basis of later valuations and gains or losses on sales are charged to gain (loss) on sales/valuation of assets, net. Expenses incurred in maintaining such properties are charged to other real estate and loan collection expenses.

Allowance for Credit Losses on Unfunded Loan Commitments

Allowance for Credit Losses on Unfunded Loan Commitments - HTLF estimates expected credit losses over the contractual term of the loan for the unfunded portion of the loan commitment that is not unconditionally cancellable by HTLF using the same collective allowance methodology for credit losses for loans described above. Management uses an estimated average utilization rate to determine the exposure at default. The allowance for unfunded commitments is recorded in the Accrued Expenses and Other Liabilities section of the consolidated balance sheets.

Mortgage Servicing and Transfers of Financial Assets, and Servicing Rights, Net

Mortgage Servicing and Transfers of Financial Assets - Prior to dissolving its mortgage operations in 2023, HTLF regularly sold residential mortgage loans to others, primarily government sponsored entities, on a non-recourse basis. Sold loans are not included in the accompanying consolidated balance sheets. HTLF generally retained the right to service the sold loans for a fee prior to the sale of its mortgage servicing rights portfolio in the first quarter of 2023. First Bank & Trust, a division of HTLF Bank, serviced mortgage loans primarily for government sponsored entities with aggregate unpaid principal balance of

Servicing Rights, Net - Mortgage and commercial servicing rights associated with loans originated and sold, where servicing is retained, are initially capitalized at fair value and recorded on the consolidated statements of income as a component of gains on sale of loans held for sale. The values of these capitalized servicing rights are amortized as an offset to the loan servicing income earned in relation to the servicing revenue expected to be earned.

First Bank & Trust, a division of HTLF Bank, sold its mortgage servicing portfolio in the first quarter of 2023, and the value of the mortgage servicing rights was derecognized on the consolidated balance sheet. In prior periods, the carrying values of these rights were reviewed quarterly for impairment based on the calculation of their fair value as performed by an outside third-party. For purposes of measuring impairment, the rights were stratified into certain risk characteristics including loan type and loan term. At December 31, 2022, no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 15 years, and no valuation allowance was required on HTLF's mortgage servicing rights with an original term of 30 years.

Premises, Furniture and Equipment, net and Premises, Furniture and Equipment Held for Sale

Premises, Furniture and Equipment, net - Premises, furniture and equipment are stated at cost less accumulated depreciation. The provision for depreciation of premises, furniture and equipment is determined by straight-line and accelerated methods over the estimated useful lives of 18 to 39 years for buildings, 15 years for land improvements and 3 to 7 years for furniture and equipment.

Premises, Furniture and Equipment Held for Sale - Premises, furniture and equipment are stated at the estimated fair value less disposal costs. Subsequent write-downs and gains or losses on the sales are recorded to gain (loss) on sales/valuation of assets, net.

Goodwill and Core Deposit Intangibles and Customer Relationship Intangibles, Net

Goodwill - Goodwill represents the excess of the purchase price of acquired subsidiaries’ net assets over their fair value at the purchase date. HTLF assesses goodwill for impairment annually, and more frequently if events occur which may indicate possible impairment, and assesses goodwill at the reporting unit level, also giving consideration to overall enterprise value as part of that assessment.

In evaluating goodwill for impairment, HTLF first assesses qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of a reporting unit is less than its carrying amount. If HTLF concludes that it is more likely than not that the fair value of a reporting unit is more than its carrying value, then no further testing of goodwill assigned to the reporting unit is required. However, if HTLF concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then HTLF performs a quantitative goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment to recognize, if any. In addition, the income tax effects of tax-deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. A goodwill impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.

Core Deposit Intangibles and Customer Relationship Intangibles, Net - Core deposit intangibles are amortized over 8 to 18 years on an accelerated basis. Customer relationship intangibles were amortized over 22 years on an accelerated basis. Annually, HTLF reviews these intangible assets for events or circumstances that may indicate a change in the recoverability of the underlying basis.

Cash Surrender Value on Life Insurance

Cash Surrender Value on Life Insurance - HTLF and its subsidiaries have purchased life insurance policies on the lives of certain officers. The one-time premiums paid for the policies, which coincide with the initial cash surrender value, are recorded as an asset. Increases or decreases in the cash surrender value, other than proceeds from death benefits, are recorded as noninterest income in income on bank owned life insurance. Proceeds from death benefits first reduce the cash surrender value attributable to the individual policy and then any additional proceeds are recorded in other noninterest income.

Income Taxes

Income Taxes - HTLF and its subsidiaries file a consolidated federal income tax return and separate or combined income or franchise tax returns as required by the various states. HTLF recognizes certain income and expenses in different time periods for financial reporting and income tax purposes. The provision for deferred income taxes is based on an asset and liability

approach and represents the change in deferred income tax accounts during the year, including the effect of enacted tax rate changes. A valuation allowance is provided to reduce deferred tax assets if their expected realization is deemed not to be more likely than not.

A tax position is recognized as a benefit only if it is "more likely than not" that the tax position would be sustained in a tax examination. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. HTLF recognizes interest and penalties related to income tax matters in income tax expense.

Derivative Financial Instruments and Mortgage Derivatives

Derivative Financial Instruments - HTLF uses derivative financial instruments as part of its interest rate risk management, which includes interest rate swaps, certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. FASB ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. As required by ASC 815, HTLF records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative and the resulting designation. Derivatives used to hedge the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives used to manage the exposure to changes in the fair value of a recognized asset or liability on the consolidated balance sheets are fair value hedges. To qualify for hedge accounting, HTLF must comply with the detailed rules and documentation requirements at the inception of the hedge, and hedge effectiveness is assessed at inception and periodically throughout the life of each hedging relationship. Hedge ineffectiveness, if any, is measured periodically throughout the life of the hedging relationship.

For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (loss) and subsequently reclassified to interest income or expense when the hedged transaction affects earnings, while the ineffective portion of changes in the fair value of the derivative, if any, is recognized immediately in other noninterest income. HTLF assesses the effectiveness of each hedging relationship by comparing the cumulative changes in cash flows of the derivative hedging instrument with the cumulative changes in cash flows of the designated hedged item or transaction. No component of the change in the fair value of the hedging instrument is excluded from the assessment of hedge effectiveness. In the first quarter of 2023 HTLF terminated its cash flow hedges. It was determined that the forecasted transactions remain probable, so the unrealized gains at termination were kept in accumulated comprehensive income and are being amortized into income over the remaining life of the forecasted transaction.

HTLF had multiple fair value hedging relationships at December 31, 2023. HTLF uses hedge accounting in accordance with ASC 815. For hedges where the fair value change in the loan portfolio is being hedged, unrealized gains and losses representing the change in fair value of the derivative and the change in fair value of the risk being hedged on the related loan are being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. For hedges where the fair value change in the investment portfolio are being hedged, the change in the fair value of the derivative and the change in the fair value of the risk being hedged on the related investments is being recorded in interest income on the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income in the consolidated statements of income. HTLF uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

HTLF also has loan interest rate swap relationships with customers to assist them in managing their interest rate risk. Upon entering into these loan swaps HTLF enters into offsetting positions with counterparties in order to minimize interest rate risk to HTLF. These back-to-back loan swaps qualify as free standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income.

HTLF does not use derivatives for speculative purposes. Derivatives not designated as hedges are not speculative and are used to manage HTLF’s exposure to interest rate movements and other identified risks, but do not meet the strict hedge accounting requirements of ASC 815.

Mortgage Derivatives - HTLF uses interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage-backed securities. These commitments are considered derivative instruments. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free-standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. As of December 31, 2023, HTLF was winding out of this activity due to dissolving its mortgage operations.

Fair Value Measurements

Fair Value Measurements - Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept). Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using discounted cash flow or other valuation techniques. Inputs into the valuation methods are subjective in nature, involve uncertainties, and require judgment and therefore cannot be determined with precision. Accordingly, the derived fair value estimates presented herein are not necessarily indicative of the amounts HTLF could realize in a current market exchange. Assets and liabilities are categorized into three levels based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine the fair value. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy in which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. HTLF's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Below is a brief description of each fair value level:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques.

Segment Reporting

Segment Reporting - Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker ("CODM"), which is the Chief Executive Officer of HTLF, in deciding how to allocate resources and assess the financial and operating performance of HTLF. HTLF’s operating segments provide, and primarily derive revenue, through full service commercial and consumer banking. HTLF has determined that the economic characteristics, operating models, performance metrics, suite of products and services, customer base, and regulatory requirements are similar for its operating segments and has therefore aggregated them into one reportable segment.

Treasury Stock

Treasury Stock - Treasury stock is accounted for by the cost method, whereby shares of common stock reacquired are recorded at their purchase price. When treasury stock is reissued, any difference between the sales proceeds, or fair value when issued for business combinations, and the cost is recognized as a charge or credit to capital surplus. HTLF had no treasury stock at December 31, 2023 and December 31, 2022.

Trust Department Assets

Trust Department Assets - Property held for customers in fiduciary or agency capacities is not included in the accompanying consolidated balance sheets because such items are not assets of HTLF Bank.

Earnings Per Share

Earnings Per Share - Basic earnings per share is determined using net income available to common stockholders and weighted average common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted average common shares and assumed incremental common shares issued.

Subsequent Events

Subsequent Events - HTLF has evaluated subsequent events that may require recognition or disclosure through the filing date of this Annual Report on Form 10-K with the SEC.

Subsequent to December 31, 2023, in February of 2024, HTLF announced that HTLF Bank had signed definitive agreements to sell its nine Rocky Mountain Bank division branches to two purchasers. The agreements include the sale of approximately $588.9 million of deposits, $365.9 million of loans and $13.6 million of premises, furniture and equipment. The transaction is expected to close in the latter half of 2024.

Effect of New Financial Accounting Standards

Effect of New Financial Accounting Standards

ASU 2022-01

In March 2022, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2022-01, "Derivatives and Hedging (Topic 815): Fair Value Hedging-Portfolio Layer Method," which expands the current last-of-layer method by allowing multiple hedged layers to be designated for a single closed portfolio of financial assets or one or more beneficial interests secured by a portfolio of financial instruments. HTLF adopted this ASU on January 1, 2023, and these amendments were applied prospectively.

ASU 2022-02

In March 2022, the FASB issued ASU 2022-02, "Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures." These amendments eliminate the troubled debt restructurings ("TDR") recognition and measurement guidance and, instead, require that an entity evaluate (consistent with the accounting for other loan modifications) whether the modification represents a new loan or a continuation of an existing loan. The amendments also enhance existing disclosure requirements and introduce new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Additionally, these amendments require that an entity disclose current-period gross charge-offs by year of origination for loans receivable within the scope of Subtopic 326-20. The guidance is effective for entities that have adopted ASU 2016-13 for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. These amendments should be applied prospectively. If an entity elects to early adopt ASU 2022-02 in an interim period, the guidance should be applied as of the beginning of the fiscal year that includes the interim period. An entity may elect to early adopt the amendments about TDRs and related disclosure enhancements separately from the amendments related to vintage disclosures. HTLF adopted this ASU on January 1, 2023, as required, and the adoption did not have a material impact on its results of operations, financial position or liquidity.

ASU 2023-02

In March 2023, the FASB issued ASU 2023-02 "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method (a consensus of the Emerging Task Force)." ASU 2023-02 expands the permitted use of the proportional amortization method, which is currently only available to low-income housing tax credit investments, to other tax equity investments if certain conditions are met. Under the proportional

amortization method, the initial cost of an investment is amortized in proportion to the income tax benefits received and both the amortization of the investment and the income tax benefits received are recognized as a component of income tax expense. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and must be applied on either a modified retrospective or a retrospective basis.

ASU 2023-06

In October 2023, the FASB issued ASU 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative." The amendments in this Update modify the disclosure or presentation requirements of a variety of Topics in the Codification. Certain of the amendments represent clarifications to, or technical corrections of, the current requirements. Each amendment in the ASU will only become effective if the SEC removes the related disclosure or presentation requirement from its existing regulations by June 30, 2027. The amendments in this ASU are not expected to have a material impact on the results of operations or financial position.

Fair Value Hierarchy

Fair Value Hierarchy

Under ASC 820, assets and liabilities are grouped at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 — Valuation is based upon quoted prices for identical instruments in active markets.

Level 2 — Valuation is based upon quoted prices for similar instruments in active markets, or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 — Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques include use of option pricing models, discounted cash flow models and similar techniques. The following is a description of valuation methodologies used for assets and liabilities recorded at fair value on a recurring or non-recurring basis.

Assets

Securities Available for Sale and Held to Maturity

Securities available for sale are recorded at fair value on a recurring basis. Securities held to maturity are generally recorded at cost. Fair value measurement is based upon quoted prices, if available. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities. Level 2 securities include U.S. government and agency securities, mortgage and asset-backed securities and private collateralized mortgage obligations, municipal bonds, equity securities and corporate debt securities. On a quarterly basis, a secondary independent pricing service is used for the securities portfolio to validate the pricing from HTLF's primary pricing service.

Equity Securities with a Readily Determinable Fair Value

Equity securities with a readily determinable fair value generally include Community Reinvestment Act mutual funds and are classified as Level 2 due to the infrequent trading of these securities. The fair value is based on the price per share.

Loans Held for Sale

Loans held for sale are carried at the lower of cost or fair value on an aggregate basis. The fair value of loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, HTLF classifies loans held for sale subjected to nonrecurring fair value adjustments as Level 2.

Loans Held to Maturity

HTLF does not record loans held to maturity at fair value on a recurring basis. However, from time to time, certain loans are considered collateral dependent and an allowance for credit losses is established. The fair value of individually assessed loans is measured using the fair value of the collateral. In accordance with ASC 820, individually assessed loans measured at fair value are classified as nonrecurring Level 3 in the fair value hierarchy.

Premises, Furniture and Equipment Held for Sale

HTLF values premises, furniture and equipment held for sale based on third-party appraisals less estimated disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in

selling bank premises, furniture and equipment, in determining the fair value of particular properties. Accordingly, the valuation of premises, furniture and equipment held for sale is subject to significant external and internal judgment. HTLF periodically reviews premises, furniture and equipment held for sale to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. Premises, furniture and equipment held for sale are measured at fair value and are classified as nonrecurring Level 3 in the fair value hierarchy.

Mortgage Servicing Rights

Mortgage servicing rights assets represent the value associated with servicing residential real estate loans that have been sold to outside investors with servicing retained. The fair value for servicing assets is determined through discounted cash flow analysis and utilizes discount rates, prepayment speeds and delinquency rate assumptions as inputs. All these assumptions require a significant degree of management estimation and judgment. Mortgage servicing rights are subject to impairment testing. The carrying values of these rights are reviewed quarterly for impairment based upon the calculation of fair value as performed by an outside third-party. For purposes of measuring impairment, the rights are stratified into certain risk characteristics including note type and note term. If the valuation model reflects a value less than the carrying value, mortgage servicing rights are adjusted to fair value through a valuation allowance. HTLF classifies mortgage servicing rights as nonrecurring with Level 3 measurement inputs.

On March 31, 2023, HTLF sold its mortgage servicing rights portfolio. The transaction qualified as a sale, and $7.7 million of mortgage servicing rights were derecognized on the consolidated balance sheet as of March 31, 2023. The book value and fair value were both $0 as of March 31, 2023.

Derivative Financial Instruments

HTLF's current interest rate risk strategy includes cash flow hedges and interest rate swaps. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. To comply with the provisions of ASC 820, HTLF incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, HTLF has considered the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Although HTLF has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2023, and December 31, 2022, HTLF has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, HTLF has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.

Interest Rate Lock Commitments

HTLF uses an internal valuation model that relies on internally developed inputs to estimate the fair value of its interest rate lock commitments which is based on unobservable inputs that reflect management's assumptions and specific information about each borrower. Interest rate lock commitments are classified in Level 3 of the fair value hierarchy.

Forward Commitments

The fair value of forward commitments is estimated using an internal valuation model, which includes current trade pricing for similar financial instruments in active markets that HTLF has the ability to access and are classified in Level 2 of the fair value hierarchy.

Other Real Estate Owned

Other real estate owned ("OREO") represents property acquired through foreclosures and settlements of loans. Property acquired is carried at the fair value of the property at the time of acquisition (representing the property's cost basis), plus any acquisition costs, or the estimated fair value of the property, less disposal costs. HTLF considers third-party appraisals, as well as independent fair value assessments from realtors or persons involved in selling OREO, in determining the fair value of particular properties. Accordingly, the valuation of OREO is subject to significant external and internal judgment. HTLF periodically reviews OREO to determine if the fair value of the property, less disposal costs, has declined below its recorded book value and records any adjustments accordingly. OREO is classified as nonrecurring Level 3 of the fair value hierarchy.

Revenue

ASC 606, Revenue from Contracts with Customers, requires revenue to be recognized at an amount that reflects the consideration to which HTLF expects to be entitled in exchange for transferring goods or services to a customer. ASC 606 applies to all contracts with customers to provide goods or services in the ordinary course of business, except for contracts that are specifically excluded from its scope. The majority of HTLF's revenue streams including interest income, loan servicing income, net securities gain and losses, net unrealized gains and losses on equity securities, net gains on sale of loans held for sale, valuation adjustment on servicing rights, income from bank owned life insurance and other noninterest income are outside the scope of ASC 606. Revenue streams including service charges and fees, interchange fees on credit and debit cards, trust fees and brokerage and insurance commissions are within the scope of ASC 606.

Service Charges and Fees

Service charges and fees consist of revenue generated from deposit account related service charges and fees, overdraft fees, customer service fees and other service charges, credit card fee income, debit card income and other service charges and fees.

Service charges on deposit accounts consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, check orders and other deposit account related fees. HTLF's performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees, including overdraft fees, are largely transaction based, and therefore, the performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

Customer service fees and other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. HTLF's performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.

Credit card fee income and debit card income are comprised of interchange fees, ATM fees, and merchant services income. Credit card fee income and debit card income are earned whenever HTLF Bank's debit and credit cards are processed through card payment networks such as Visa. ATM fees are primarily generated when a Bank cardholder uses an ATM that is not owned by one of HTLF's Banks or a non-bank cardholder uses HTLF-owned ATM. Merchant services income mainly represents fees charged to merchants to process their debit and credit card transactions, in addition to account management fees.

Trust Fees

Trust fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. HTLF's performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the average daily market value or month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days before or after month end through a direct charge to customers’ accounts. HTLF does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. HTLF's performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time (i.e., as incurred). Payment is received shortly after services are rendered.

Brokerage and Insurance Commissions

Brokerage commission primarily consists of commissions related to broker-dealer contracts. The contracts are between the customer and the broker-dealer, and HTLF satisfies its performance obligation and earns commission when the transactions are completed. The recognition of revenue is based on a defined fee schedule and does not require significant judgment. Payment is received shortly after services are rendered. Insurance commissions are related to commissions received directly from the insurance carrier. HTLF acts as an insurance agent between the customer and the insurance carrier. HTLF's performance obligations and associated fee and commission income are defined with each insurance product with the insurance company. When insurance payments are received from customers, a portion of the payment is recognized as commission revenue.

Contract Balances

HTLF does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2023, 2022, and 2021, HTLF did not have any significant contract balances or capitalized contract acquisition costs.

Quantitative Information on Assets Measured at Fair Value on Recurring and Nonrecurring Basis Using Level 3

The following tables present additional quantitative information about assets measured at fair value on a recurring and nonrecurring basis and for which HTLF has utilized Level 3 inputs to determine fair value, in thousands:

	Fair Value at 12/31/23		Valuation Technique	Unobservable Input	Range (Weighted Average)
Premises, furniture and equipment held for sale	$	4,069	Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-10%(2)
Other real estate owned	12,548		Modified appraised value	Third-party appraisal	(1)
				Appraisal discounts	0-10%(2)
Collateral dependent individually assessed loans:
Commercial and industrial	23,422		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-12%(2)
Owner occupied commercial real estate	30,400		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-20%(2)
Non-owner occupied commercial real estate	—		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-10%(2)
Real estate construction	642		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-10%(2)
Agricultural and agricultural real estate	4,768		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0%-10%(2)
Residential real estate	741		Modified appraised value	Third-party appraisal	(1)
				Appraisal discount	0-10%(2)
(1) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(2) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.

	Fair Value at 12/31/22		Valuation Technique	Unobservable Input	Range (Weighted Average)
Interest rate lock commitments	$	174	Discounted cash flows	Closing ratio	0 - 99% (88%)(1)
Premises, furniture and equipment held for sale	6,851		Modified appraised value	Third-party appraisal	(2)
				Appraisal discount	0-10%(3)
Other real estate owned	8,401		Modified appraised value	Third-party appraisal	(2)
				Appraisal discounts	0-10%(3)
Servicing rights	7,840		Discounted cash flows	Discount rate	9.98 - 11.72% (10.02%)(4)
				Constant prepayment rate	7.8 - 14.2% (7.9%)(4)
Collateral dependent individually assessed loans:
Commercial and industrial	12,042		Modified appraised value	Third-party appraisal	(2)
				Appraisal discount	0-10%(3)
Owner occupied commercial real estate	7,556		Modified appraised value	Third-party appraisal	(2)
				Appraisal discounts	0-10%(3)
Non-owner occupied commercial real estate	11,371		Modified appraised value	Third-party appraisal	(2)
				Appraisal discounts	0-10%(3)
Real estate construction	1,518		Modified appraised value	Third-party appraisal	(2)
				Appraisal discount	0-10%(3)
Agricultural and agricultural real estate	3,788		Modified appraised value	Third-party appraisal	(2)
				Appraisal discount	0-15%(3)
Residential real estate	1,607		Modified appraised value	Third-party appraisal	(2)
				Appraisal discount	0-10%(3)
(1) The significant unobservable input used in the fair value measurement is the closing ratio, which represents the percentage of loans currently in a lock position which management estimates will ultimately close. The closing ratio calculation takes into consideration historical data and loan-level data.
(2) Third-party appraisals are obtained and updated at least annually to establish the value of the underlying asset, but the disclosure of the unobservable inputs used by the appraisers would not be meaningful because the range will vary widely from appraisal to appraisal.
(3) Discounts applied to the appraised values primarily include estimated sales costs, but also consider the age of the appraisal, changes in local market conditions and changes in the current condition of the collateral.
(4) The significant unobservable inputs used in the discounted cash flow analysis are the discount rate and constant prepayment rate.

Summary of Changes in Fair Value of Level 3 Assets Measured at Fair Value on Recurring Basis

Fair Value, by Balance Sheet Grouping

The following analysis, which is inherently limited in depicting fair value, also does not consider any value associated with either existing customer relationships or the ability of HTLF to create value through loan origination, obtaining deposits or fee generating activities. Many of the estimates presented below are based upon the use of highly subjective information and assumptions and, accordingly, the results may not be precise. Management believes that fair value estimates may not be comparable between financial institutions due to the wide range of permitted valuation techniques and numerous estimates which must be made. Furthermore, because the disclosed fair value amounts were estimated as of the balance sheet date, the amounts actually realized or paid upon maturity or settlement of the various financial instruments could be significantly different.
