	•	the effects of any federal government shutdown;
	•	the credit risks of lending activities, including changes in loan delinquencies, write-offs and the allowance for credit losses;

the impact of bank failures or adverse developments at other banks and related negative publicity about the banking industry in general on investor and depositor sentiment;

•

results of examinations of the Federal Reserve and the Bank by the Federal Deposit Insurance Corporation ("FDIC") and the South Carolina State Board of Financial Institutions, or other regulatory authorities, including the possibility that any such regulatory authority may, among other things, require us to increase our reserve for credit losses, write-down assets, change our regulatory capital position or affect our ability to borrow funds or maintain or increase deposits, or impose additional requirements or restrictions on us, any of which could adversely affect our liquidity and earnings;

•

legislative or regulatory changes, including changes in banking, securities and tax laws, and in regulatory policies and principles, or the interpretation of regulatory capital or other rules;

•

our ability to attract and retain deposits;

•

our ability to control operating costs and expenses;

•

our ability to implement our business strategies, including expectations regarding key growth initiatives and strategic priorities;

•

the use of estimates in determining the fair value of certain of our assets, which estimates may prove to be incorrect and result in significant declines in valuation;

•

difficulties in reducing risks associated with the loans on our balance sheet;

•

staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our workforce and potential associated charges;

•

disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems or critical third-party vendors;

our ability to attract and retain key members of our senior management team;

•

costs and effects of litigation, including settlements and judgments;

	•	effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, civil unrest and other external events on our business;
	•	other economic, competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services; and

•

other risks described elsewhere in this Annual Report on Form 10-K for the year ended December 31, 2025 ("2025 Form 10-K") and in the Company's other reports filed with or furnished to the Securities and Exchange Commission (the “SEC”).

Any of the forward-looking statements that we make may turn out to be inaccurate as a result of our beliefs and assumptions we make in connection with the factors set forth above or because of other unidentified and unpredictable factors. Because of these and other uncertainties, our actual future results may be materially different from the results indicated by these forward-looking statements and you should not rely on such statements. The Company undertakes no obligation to publish revised forward- looking statements to reflect the occurrence of unanticipated events or circumstances after the date hereof. These risks could cause our actual results for 2026 and beyond to differ materially from those expressed in any forward-looking statements by or on behalf of us, and could negatively affect the Company’s consolidated financial condition and consolidated results of operations, liquidity and stock price performance.

As used throughout this report, the terms "we," "our," or "us" refer to Security Federal Corporation and our consolidated subsidiary, Security Federal Bank.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

PART I

Item 1. Business

Security Federal Corporation

Security Federal Corporation (the "Company") was incorporated under the laws of the State of Delaware in July 1987 for the purpose of becoming the savings and loan holding company for Security Federal Bank ("Security Federal" or the "Bank") upon the Bank's conversion from mutual to stock form (the "Conversion"). Effective August 17, 1998, the Company changed its state of incorporation from Delaware to South Carolina. On December 28, 2011, the Company reorganized into a bank holding company in connection with the Bank's conversion from a federally chartered stock savings bank to a South Carolina chartered commercial bank. As a result of the reorganization, the Federal Reserve became the Company's primary federal regulator.

As a South Carolina corporation, the Company is authorized to engage in any activity permitted by South Carolina General Corporation Law. The Company is a one bank holding company. Through the bank holding company structure, it is possible to expand the size and scope of the financial services offered beyond those currently offered by the Bank. The holding company structure also provides the Company with greater flexibility than the Bank would have to diversify its business activities, through existing or newly formed subsidiaries, or through acquisitions or mergers of financial institutions as well as other companies. There are no current arrangements, understandings or agreements regarding any such acquisition. Future activities of the Company will be funded through the continuing operations of Security Federal and through borrowings from third parties. Activities of the Company may also be funded through sales of additional securities or income generated by other activities of the Company. At this time, there are no plans regarding sales of additional securities or other activities.

At December 31, 2025, the Company, on a consolidated basis with the Bank, had assets of $1.6 billion, loans receivable, net, of $673.1 million, deposits of $1.4 billion and shareholders' equity of $200.5 million. The executive office of the Company is located at 238 Richland Avenue Northwest, Aiken, South Carolina 29801, and its telephone number is (803) 641-3000.

Security Federal Bank

Security Federal is a South Carolina chartered commercial bank headquartered in Aiken, South Carolina. Security Federal, with 19 branch offices in Aiken, Lexington, Richland and Saluda counties in South Carolina and Columbia and Richmond counties in Georgia, was originally chartered under the name Aiken Building and Loan Association on March 27, 1922. It received its federal charter and changed its name to Security Federal Savings and Loan Association of Aiken on March 7, 1962, and later changed its name to Security Federal Savings Bank of South Carolina, on November 11, 1986. Effective April 8, 1996, the Bank changed its name to Security Federal Bank. The Bank converted from the mutual to the stock form of organization on October 30, 1987. As mentioned above, effective December 28, 2011, Security Federal converted from a federally chartered stock savings bank to a South Carolina chartered commercial bank. As a result of the conversion to a South Carolina commercial bank, the Bank is regulated by the State Board and the FDIC. Security Federal has two active wholly owned subsidiaries: Security Federal Investments, Inc. ("SFINV") and Security Federal Insurance, Inc. (“SFINS”). SFINV was formed to hold investment securities and allow for better management of the securities portfolio. SFINS is an insurance agency offering auto, business, and home insurance.

In 2010, the Bank and the Company applied for and became a Certified Community Development Financial Institution ("CDFI"). The designation enables the Bank to be eligible for certain grants from United States Treasury ("Treasury"). The Treasury administers CDFIs and the Bank and Company must re-certify as a CDFI every year. Re-certification currently depends on the Bank making a percentage of its loans by dollar and number of loans in its Target Market, which consists primarily of low to moderate income census tracts in the Bank’s market area. The criteria to remain a CDFI can change from year to year.

On May 24, 2022, the Company entered into a Letter Agreement (“Agreement”) with the Treasury under the Emergency Capital Investment Program (“ECIP”). Established by the Consolidated Appropriations Act, 2021, the ECIP was created to encourage CDFIs and minority depository institutions to provide loans, grants, and forbearance for small businesses, minority-owned businesses, and consumers, especially low-income and underserved communities, by providing direct and indirect capital investments in CDFIs. Pursuant to the Agreement, the Company agreed to issue and sell 82,949 shares of Preferred Stock for an aggregate purchase price of $82.9 million in cash. This ECIP investment is treated as tier 1 capital. The Preferred Stock bears no dividend for the first 24 months following the investment date. Thereafter, the dividend rate will be adjusted, not higher than 2%, based on the lending growth criteria listed in the Agreement. After the tenth anniversary of the investment date, the dividend rate will be fixed based on the average annual amount of lending in years 2 through 10. Dividends will be payable quarterly in arrears on March 15, June 15, September 15, and December 15. The Preferred Stock may be redeemed at the option of the Company on or after the fifth anniversary of issuance (or earlier in the event of loss of regulatory capital treatment), subject to the approval of the appropriate federal banking regulator and in accordance with the federal banking agencies’ regulatory capital regulations.

The principal business of Security Federal is accepting deposits from the general public and originating commercial real estate loans, commercial and agricultural business (non-real estate) loans, consumer loans, as well as mortgage loans to buy or refinance one-to-four family residential real estate. The Bank also originates construction loans on single-family residences, multi-family dwellings and projects, and commercial real estate, as well as loans for the acquisition, development and construction of residential subdivisions and commercial projects. Security Federal's income is derived primarily from interest and fees earned in connection with its lending activities, and its principal expenses are interest paid on savings deposits and borrowings and operating expenses. In addition, the Bank operates Security Federal Trust and Investments, a division of the Bank that offers trust, financial planning and financial management services.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Lending Activities

Security Federal's principal lending activities include originating loans on commercial real estate and one-to-four family residential real estate. The Bank originates fixed rate residential real estate loans for sale in the secondary market and adjustable rate mortgage ("ARM") loans to be held in its portfolio. The Bank also originates construction loans on single family residences, multi-family dwellings and commercial real estate, and loans for the acquisition, development and construction of residential subdivisions and commercial projects. To a lesser extent, the Bank originates consumer loans and commercial and agricultural business loans.

The loan-to-value ratio, maturity and other provisions of loans made by the Bank reflect its policy of making the maximum loan permissible consistent with applicable regulations, established lending policies and market conditions. The Bank requires title insurance (or acceptable legal opinions on smaller loans secured by real estate), fire insurance, and flood insurance where applicable, on loans secured by improved real estate.

Loan Portfolio Composition

Loans receivable, net, including loans held for sale, decreased to $676.2 million at December 31, 2025 from $687.1 million at December 31, 2024, due to a decrease in construction loans. For a detailed breakdown of the composition of our loan portfolio, see "Note 4 - Loans Receivable, Net" of the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

The following schedule illustrates the maturities of Security Federal's loan portfolio, excluding loans held for sale, at December 31, 2025. Mortgages which have adjustable or renegotiable interest rates are shown as maturing in the period when the contract is due. This schedule does not reflect the effects of possible prepayments or enforcement of due-on-sale clauses.

Loan Originations/ Renewals, Purchases and Sales

In addition to interest earned on loans, the Bank receives loan origination fees or "points" for originating loans. Loan origination points are a percentage of the principal amount of the loan which are charged to the borrower for the creation of the loan. The Bank's loan origination fees are generally 1% on conventional residential mortgages, and 0.25% to 1% on commercial real estate loans and commercial and agricultural loans.

Loan origination and commitment fees are volatile sources of income. These fees vary with the volume and type of loans and commitments made and purchased and with competitive conditions in mortgage markets, which in turn are governed by the demand for and availability of money. The Bank also receives other fees and charges related to existing loans, conversion fees, assumption fees, late charges and other fees collected in connection with a change in borrower or other loan modifications.

Security Federal currently sells substantially all conforming fixed rate loans with terms of 15 years or greater in the secondary mortgage market. These loans are sold in order to provide a source of funds and as one of the strategies available to close the gap between the maturities of the Bank's interest-earning assets and interest-bearing liabilities. Currently, most fixed rate, long-term mortgage loans are being originated based on Federal National Mortgage Association ("Fannie Mae") and Federal Home Loan Mortgage Corporation ("Freddie Mac") underwriting standards.

Secondary market sales are made to other banks or institutional investors. Generally, all loans sold to investors are without recourse. For the past several years, substantially all loans have been sold on a servicing released basis. During the year ended December 31, 2025, Security Federal sold $39.8 million in fixed rate residential loans on a servicing released basis in the secondary market. Loans closed but not yet settled with banks or other investors, are carried in the Bank's "loans held for sale" portfolio. At December 31, 2025, the Bank had $3.1 million of loans held for sale. These loans are fixed rate residential loans that have been originated in the Bank's name and have closed. Virtually all these loans have commitments to be purchased by investors and the majority of these loans were price locked with the investors on the same day or shortly after the loan was price locked with the Bank's customers. Therefore, these loans present little market risk for the Bank. The Bank usually delivers loans to, and receives funding from, the investor within 30 days. Security Federal originates all its loans held for sale on a "best efforts" basis, meaning that the Bank suffers no penalty if it is unable to deliver a loan to a potential investor.

Federal law restricts the Bank's permissible lending limits to one borrower to the greater of $500,000 or 15% of unimpaired capital and surplus. At December 31, 2025, the Bank's legal lending limit under this restriction was $26.6 million. At that date, the Bank's largest loan relationship to a single borrower was $21.0 million, comprised of one commercial line of credit to a public charter school. This loan was performing in accordance with its repayment terms at December 31, 2025.

South Carolina law restricts the Bank's permissible lending limits to one borrower to 10% of unimpaired capital, or $17.7 million at December 31, 2025, unless prior approval is granted by a two-thirds vote of the Board of Directors, in which case the limit is increased to 15% of unimpaired capital. The Board approved the increased loan limits to 15% of unimpaired capital in 2024.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Loan Solicitation and Processing

The Bank actively solicits mortgage loan applications from existing customers, real estate agents, builders, real estate developers and others. The Bank also receives mortgage loan applications from customer referrals and from walk-in customers. Detailed loan applications are obtained to determine the borrower's creditworthiness and ability to repay. The more significant items on loan applications are verified using credit reports, financial statements and confirmations. After analysis of the loan application and property or collateral involved, including an appraisal of the property (residential appraisals are obtained through independent fee appraisers), a lending decision is made in accordance with the underwriting guidelines of the Bank. These guidelines are generally consistent with Freddie Mac and Fannie Mae guidelines for residential real estate loans. With respect to commercial real estate loans, the Bank also reviews the capital adequacy of the business, the income potential of the property, the ability of the borrower to repay the loan and honor its other obligations, and general economic and industry conditions.

Upon receipt of a loan application and all required related information from a prospective borrower, the loan application is submitted for approval or rejection. The residential mortgage loan underwriters approve loans which meet Freddie Mac and Fannie Mae underwriting requirements. The Chairman of the Company, the Chief Executive Officer of the Company and the Bank, the President of the Bank, the President of the Company, the Chief Financial Officer, the Executive Vice President/Business Development, the Senior Vice President/Chief Lending Officer and Senior Vice President/Mortgage Lending individually have the authority to approve loans of $500,000 or less, except as set forth above for conforming conventionally underwritten, single family mortgage loans, which are approved by the underwriters. Loans in excess of $500,000 and up to $1.0 million require the approval of any three of the following: Chairman of the Company, the Chief Executive Officer of the Company and the Bank, the President of the Bank, the President of the Company, the Chief Financial Officer, the Executive Vice President/Financial Services, the Chief Lending Officer, or the Secretary of the Executive Committee. Any loan in excess of $1.0 million must be approved by the Bank's Executive Committee, which operates as the Bank's Loan Committee. The loan approval limits discussed above are the aggregate of all loans to any one borrower or entity, not including loans that are secured by the borrower's primary residence, and are conventionally underwritten.

The general policy of Security Federal is to issue loan commitments to qualified borrowers for a specified term, generally for a period of 45 days or less. With management approval, commitments may be extended for up to an additional 45 days. At December 31, 2025 , the Bank had $1.3 million in outstanding commitments on mortgage loans not yet closed compared to $1.1 million at December 31, 2024 . Security Federal had outstanding commitments available on all lines of credit (including letters of credit, commercial, undisbursed loans in process, home equity, credit cards and other consumer loans) totaling $141.1 million at December 31, 2025 . For a more detailed discussion, see "Note 18 - Commitments and Contingencies" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

Residential and Construction Real Estate Lending

At December 31, 2025, the Bank had $219.9 million, or 32.0% of its total outstanding loan portfolio, in residential mortgage loans. These loans have adjustable or fixed rates and include permanent residential mortgage loans.

Security Federal offers a variety of ARM loans with adjustable rates of interest which vary according to specified indices. The Bank's ARM loans generally have a loan term of 15 to 30 years with initial rate adjustments every one, three, five or seven years during the term of the loan. After the initial rate adjustment, the loan rate then adjusts annually. Most of the Bank's ARM loans contain a 200 basis point limit as to the maximum amount of change in the interest rate at any adjustment period and a 500 or 600 basis point limit over the life of the loan. The Bank generally originates ARM loans to retain in its portfolio. These loans are generally made consistent with Freddie Mac and Fannie Mae guidelines. The Bank sells the majority of its longer term fixed rate mortgage loans at origination.

Despite the benefits of ARM loans to the Bank's asset/liability management program, these loans also pose potential additional risks, primarily because as interest rates rise, the underlying payment by the borrower rises, increasing the potential for default. At the same time, marketability of the underlying property may be adversely affected by higher interest rates.

When originating residential mortgage loans, the Bank assesses the borrower's creditworthiness, evaluates their ability to make principal and interest payments, and considers the property's value securing the loan. The Bank generally makes loans on residential properties in amounts of 95% or less of the appraised value of the collateral. When loans are made for amounts which exceed 80% of the appraised value of the underlying real estate, the Bank's general policy is to require private mortgage insurance on the portion of the loan in excess of 80% of the appraised value. In general, the Bank restricts its residential lending to South Carolina and the nearby Evans and Augusta, Georgia market.

Many of the residential mortgage loans we retain in our portfolio consist of loans that do not satisfy acreage limits, income, credit, conforming loan limits (i.e., jumbo mortgages) or various other requirements imposed by Freddie Mac or Fannie Mae. Some of these loans are also originated to meet the needs of borrowers who cannot otherwise satisfy Freddie Mac or Fannie Mae credit requirements because of personal and financial reasons (i.e., bankruptcy, length of time employed, etc.), and other aspects, which do not conform to their underwriting guidelines. Such borrowers may have higher debt-to-income ratios, or the loans are secured by unique properties in rural markets for which there are no sales of comparable properties to support the value according to secondary market requirements. We may require additional collateral or lower loan-to-value ratios to reduce the risk of these loans. We believe that these loans satisfy the needs of borrowers in our market area. As a result, subject to market conditions, we intend to continue to originate these types of loans. We also retain jumbo loans which exceed the conforming loan limits and therefore, are not eligible to be purchased by Freddie Mac or Fannie Mae.

Construction loans consist of loans to construct a borrower's primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date. These loans are typically secured by undeveloped or partially developed land in anticipation of completing construction of a 1-4 family residential property. Construction loans are generally made for periods of six months to one year with either adjustable or fixed rates. At December 31, 2025, construction loans totaled $66.6 million, or 9.7%, of the Bank's loan portfolio. On loans of this type, the Bank seeks to evaluate the financial condition and prior performance of the builder, as well as the borrower's creditworthiness and his or her general ability to make principal and interest payments, and the value of the property that will secure the loan. On construction loans offered to individuals (non-builders), the Bank offers a construction/permanent loan. The borrower pays interest on the loan during the one year construction phase. After construction, the loan then automatically converts, depending on the borrower's upfront selection, to a one year ARM, a three year/one year ARM, or a five year/one year ARM loan in which the borrower will pay principal and interest. The borrower also has the option, after the construction period only, to convert the loan to a fixed rate residential mortgage loan which the Bank sells on the secondary market on a servicing released basis.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Commercial Real Estate

The commercial real estate loans originated by the Bank are primarily secured by non-residential commercial properties, churches, hotels, and residential developments. At December 31, 2025, the Bank had $295.3 million, or 43.0% of its total loan portfolio, in commercial real estate loans.

Commercial real estate loans from the Bank typically have amortization terms ranging from 10 to 20 years, offered with either adjustable or fixed rates. Adjustable rates are linked to the prime rate as quoted in The Wall Street Journal, adjusting daily, with instituted floors (typically 4% to 6%). In cases where ceilings are applied, the loan will typically require a balloon payment within 60 months. Fixed-rate commercial real estate loans usually involve a balloon payment within 36 to 60 months.

Commercial real estate lending entails significant additional credit risk when compared to residential lending. Commercial real estate loans typically involve large loan balances to single borrowers or groups of related borrowers. Because payments on loans secured by commercial properties often depend upon the successful operation and management of the properties, repayment of these loans may be affected by adverse conditions in the real estate market or the economy. To minimize the risks associated with this type of loan, the Bank generally limits the maximum loan-to-value ratio for commercial real estate to a range of 65% to 80%, based on appraisals of the property at the time of the loan by appraisers designated by the Bank, and strictly scrutinizes the credit history, financial condition and cash flow of the borrower, the quality of the collateral and the expertise of management of the property securing the loan. Although the creditworthiness of the business and its principals is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.

Commercial and Agricultural Business (Non Real Estate) Loans

Commercial and agricultural business loans originated by the Bank are primarily secured by business equipment, furniture and fixtures, inventory and receivables, or are unsecured. At December 31, 2025, the Bank had $37.9 million, or 5.5% of its total loan portfolio, in commercial and agricultural business loans.

Commercial and agricultural business loans are typically originated on terms of three to 60 months, featuring both adjustable and fixed interest rate terms. Adjustable rates are tied to the prime rate as quoted in The Wall Street Journal, adjusting daily, with floors (typically 4% to 6% since 2009) set by the Bank. Loans with ceilings usually involve a balloon payment in 60 months. Fixed-rate commercial and agricultural business loans typically have an amortization period of five years or less.

Commercial and agricultural business lending generally involves greater risk than residential mortgage lending and involves risks that are different from those associated with lending that is secured by real estate. Real estate lending is generally considered to be collateral based lending with loan amounts based on predetermined loan-to-collateral values, and liquidation of the underlying real estate collateral is viewed as the primary source of repayment in the event of borrower default. Although commercial and agricultural business loans often have equipment, inventory, accounts receivable or other business assets as collateral, the liquidation of collateral in the event of a borrower default is often not a sufficient source of repayment because accounts receivable may be uncollectible and inventories and equipment may be obsolete or of limited use, among other conditions. Accordingly, the repayment of a commercial and agricultural business loan depends primarily on the creditworthiness of the borrower (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. The Bank seeks to minimize these risks by strictly scrutinizing the borrower's current financial condition, ability to pay, past earnings and payment history. In addition, the current financial condition and payment history of all principals are reviewed. Typically, the Bank requires the principal or owners of a business to guarantee all loans made to their business by the Bank. Although the creditworthiness of the business and its principals is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.

HELOC and Consumer Loans

The Bank provides consumer loans for various personal, family or household purposes, covering financing for home improvements, residential lots, automobiles, boats, mobile homes, recreational vehicles and education. Additionally, the Bank offers home equity lines of credit ("HELOCs"), which are open-end lines secured by mortgage liens on the borrower's primary or secondary residence. Borrowers make minimum interest-only monthly payments on drawn lines. HELOC terms extend up to a maximum of 20 years, with a variable interest rate tied to the prime rate and floats monthly.

The Bank has interest rate floors, currently ranging from 3.00% to 6.00%, for new HELOC originations, with a maximum loan-to-value ratio of 80%. The Bank also offers secured and unsecured lines of credit. Although consumer loans typically involve a higher level of risk than residential mortgage loans, they generally provide higher yields and have shorter terms to maturity. At December 31, 2025, the Bank had $43.0 million in outstanding HELOCs, representing 6.3% of its loan portfolio.

At December 31, 2025, the Bank also had $23.9 million in other consumer loans, constituting 3.5% of its loan portfolio, which included amounts outstanding on credit cards and personal lines of credit. As of December 31, 2025, the Bank had issued approved credit card lines of $16.7 million, with $3.5 million outstanding on the same date.

The Bank's underwriting standards for consumer loans include a determination of the applicant's payment history on other debts and an assessment of ability to meet existing obligations and payments on the proposed loan. The stability of the applicant's monthly income is determined by verification of gross monthly income from primary employment, and from any verifiable secondary income. Although creditworthiness of the applicant is of primary consideration, the underwriting process also includes a comparison of the value of the security, if any, in relation to the proposed loan amount.

Loan Delinquencies and Defaults

The Bank's collection procedures provide that when a residential or commercial real estate loan is approximately 20 days past due, the borrower is contacted by mail and payment is requested. If the delinquency continues for another 10 days, subsequent efforts are made to contact the delinquent borrower and establish a program to bring the loan current. In certain instances, the Bank may modify the loan or grant a limited moratorium on loan payments to enable the borrower to reorganize his financial affairs. If the loan continues in a delinquent status for 60 days or more, the Bank generally initiates foreclosure proceedings after the customer has been notified by certified mail. The Bank had $5.8 million in non-accrual loans at December 31, 2025 compared to $7.6 million at December 31, 2024. For a more detailed discussion of our non-accrual loans, see "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Note 4 - Loans Receivable, Net" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Classified Assets

Federal regulations provide for the classification of loans and other assets such as debt and equity securities considered to be of lesser quality as "substandard," "doubtful" or "loss" assets. The regulations require commercial banks to classify their own assets and to establish prudent general allowances for loan losses for assets classified "substandard" or "doubtful." For the portion of assets classified as "loss," an institution is required to either establish specific allowances of 100% of the amount classified or charge off such amount. In addition, the State Board and/or FDIC may require the establishment of a general allowance for credit losses based on assets classified as "substandard" and "doubtful" or based on the general quality of the asset portfolio of a Bank. See "Regulation - Regulation of the Bank."

The Company uses a risk-based approach based on the following credit quality measures consistent with regulatory guidelines when analyzing the loan portfolio: pass, caution, special mention, and substandard. For a more detailed discussion of our credit quality measures, see "Note 4- Loans Receivable, Net - Credit Quality Indicators" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

At December 31, 2025, $15.2 million of the total loan balance was classified "substandard" compared to $16.1 million at December 31, 2024. At December 31, 2025, $13.1 million of the total loan balance was designated as "special mention" compared to $20.5 million at December 31, 2024. At December 31, 2025, $201.6 million of the total loan balance was designated as “caution” compared to $176.9 million at December 31, 2024. The Bank had no loans classified as "doubtful" or "loss" at December 31, 2025 and 2024.

Modifications to Borrowers Experiencing Financial Difficulty

The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification.

Modifications made to borrowers experiencing financial difficulty typically have their impact already factored into the allowance for credit losses. This is due to the measurement methodologies utilized in estimating the allowance. Consequently, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, the Company modifies loans by providing principal forgiveness on certain of its real estate loans. When principal forgiveness is provided, the amortized cost basis of the asset is written off against the allowance for credit losses. The amount of the principal forgiveness is deemed to be uncollectible; therefore, that portion of the loan is written off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses.

In some cases, the Company will modify a certain loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. As such multiple types of modifications may have been made on the same loan within the current reporting period each much be reported. The combination is at least two of the following: a term extension, principal forgiveness, and interest rate reduction. Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.

Allowance for Credit Losses on Loans

Security Federal recognizes that it will experience credit losses during the course of making loans and that the risk of loss will vary with, among other things, the type of loan being made, the creditworthiness of the borrower over the term of the loan and, in the case of a secured loan, the quality of the underlying security for the loan. The Bank seeks to establish and maintain sufficient reserves for estimated losses on specifically identified loans and real estate where such losses can be estimated. Additionally, general reserves for estimated possible losses are established on specified portions of the Bank's portfolio such as consumer loans and higher risk residential construction mortgage loans based on management's estimate of the potential loss for loans which normally can be classified as higher risk. Specific and general reserves are based on, among other criteria: (1) the risk characteristics of the loan portfolio, (2) current economic conditions on a local as well as a statewide basis, (3) actual losses experienced historically and (4) the level of reserves for possible losses in the future.

The allowance for credit losses on loans represents management’s estimate of lifetime credit losses inherent in loans as of the balance sheet date. The allowance for credit losses on loans is estimated by management using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. In determining the adequacy of the allowance for credit losses on loans, management reviews relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The level of the allowance for credit losses reflects management's continuing evaluation of this risk based on the Bank's past loss experience. The allowance is management's best estimate for offsetting risk for our estimated possible losses. There can be no guarantee that the estimate is adequate or accurate. Management believes that the allowance for credit losses on loans is at a level adequate to provide for inherent loan losses. Although management believes that it has considered all relevant factors in its estimation of future losses, future adjustments to the allowance may be necessary if conditions change substantially from the assumptions used in making the original estimations. Regulators will from time to time evaluate the allowance for credit losses which is subject to adjustment based upon the information available to the regulators at the time of their examinations.

For a breakdown of the activity within the allowance for credit losses by loan category for the years ended December 31, 2025 and 2024, see "Note 4- Loans Receivable, Net - Allowance for Credit Losses" in the Notes to Consolidated Financial Statements contained in “Item 8.

Subsidiaries

At December 31, 2025, the Company had two subsidiaries, Security Federal, its wholly owned operating bank subsidiary, and Security Federal Statutory Trust (the “Trust”), which issued and sold fixed and floating rate capital securities of the Trust. Under current accounting guidance, the Trust is not consolidated in the Company’s financial statements.

At December 31, 2025, Security Federal had two subsidiaries, SFINV and SFINS. SFINV was formed to hold investment securities and allow for better management of the securities portfolio. SFINS is an insurance agency offering auto, business and home insurance. Security Federal's net investment in its subsidiaries totaled $40.9 million at December 31, 2025.

Investment Activities

The Bank has authority to invest in various types of liquid assets, including U.S. Treasury obligations and securities of various federal agencies, certificates of deposit at insured institutions, mutual funds, bankers' acceptances and federal funds. The Bank may also invest a portion of its assets in certain commercial paper and corporate debt securities. See "Regulation - Regulation of the Bank."

As a member of the Federal Home Loan Bank ("FHLB") System, Security Federal must maintain minimum levels of investments that are liquid assets as defined in Federal regulations. See "Regulation - Regulation of the Bank - Federal Home Loan Bank System." Liquidity may increase or decrease depending upon the availability of funds and comparative yields on investments in relation to the return on loans. Historically, the Bank has maintained its liquid assets at a level believed adequate to meet requirements of normal daily activities, repayment of maturing debt and potential deposit outflows. Management regularly reviews and updates cash flow projections to ensure that adequate liquidity is provided.

At December 31, 2025, our investment portfolio totaled $776.3 million. Security Federal has an investment portfolio of available for sale ("AFS") and held to maturity ("HTM") securities, the majority of which are mortgage-backed securities ("MBS"). MBS can serve as collateral for borrowings and, through repayments, as a source of liquidity. MBS do not have a fixed maturity date. Under the Bank's risk-based capital requirement, MBS have a risk weight of 20% (or 0% in the case of Government National Mortgage Association ("Ginnie Mae") securities) compared to the 50% risk weight carried by residential loans. Small Business Administration ("SBA") bonds are backed by the full faith and credit of the U.S. government and carry a zero percent risk base when calculating risk-based assets for regulatory capital purposes. Student loan pools are typically 97% guaranteed by the U.S. government. The FHLB, Fannie Mae and Freddie Mac are government sponsored enterprises ("GSEs") and the securities and bonds issued by GSEs are not backed by the full faith and credit of the U.S. government. AFS securities are carried at fair value.

HTM securities are carried at amortized cost, adjusted for the amortization of any related premiums or the accretion of any related discounts into interest income. For more detailed information regarding the Bank's investment portfolios, see "Note 2 - Investments, Available for Sale" and "Note 3 - Investments, Held to Maturity" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

Sources of Funds

Deposit accounts have traditionally been a principal source of the Bank's funds for use in lending and for other general business purposes. The Bank attracts both short-term and long-term deposits from the general public by offering a wide assortment of account types and rates. The Bank offers regular savings accounts, checking accounts, various money market accounts, fixed interest rate certificates with varying maturities, and individual retirement accounts. In addition to deposits, the Bank derives funds from loan repayments, cash flows generated from operations (including interest credited to deposit accounts), FHLB of Atlanta advances, borrowings from the Federal Reserve Bank ("FRB") of Richmond, sales of investment securities, sales of securities under agreements to repurchase, and loan sales. See "Borrowings" below. Scheduled loan payments are a relatively stable source of funds while deposit inflows and outflows and the related cost of such funds have varied widely. FHLB of Atlanta advances, borrowings from the FRB and the sale of securities under agreements to repurchase, referred to as retail repurchase agreements, may be used on a short-term basis to compensate for seasonal reductions in deposits or deposit inflows at less than projected levels and may be used on a longer-term basis in support of expanded lending activities. The availability of funds from loan and investment sales is influenced by general interest rates. For additional information, see "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in this 2025 Form 10-K.

Deposits

The Bank attracts both short-term and long-term deposits from the general public by offering a wide assortment of account types and rates. The Bank offers regular savings accounts, checking accounts, various money market accounts, fixed interest rate certificates with varying maturities, negotiated rate $100,000 or above jumbo certificates of deposit ("Jumbo CDs") and individual retirement accounts. The Bank believes that, based on its experience over the past several years, its savings and transaction accounts are stable sources of deposits. The Bank relies upon locally obtained Jumbo CDs to maintain its deposit levels. At December 31, 2025, deposits totaled $1.4 billion. At that date, approximately $334.4 million of our deposit portfolio was uninsured, including $129.8 million in public deposits which are fully collateralized and $14.0 million in Bank-owned demand deposit accounts. The uninsured amounts are estimates based on the methodologies and assumptions used for the Bank’s regulatory reporting requirements.

At December 31, 2025 and 2024, the Bank had no deposit relationships greater than 5.0% of outstanding deposits.

Borrowings

We had no borrowings outstanding under the Federal Reserve discount window at December 31, 2025, compared to $50.0 million in borrowings outstanding under the Federal Reserve Bank Term Funding Program (“BTFP”) with a weighted average borrowing rate of 4.76% at December 31, 2024. The Company elected to participate in the BTFP to refinance existing FRB discount window borrowings at a lower fixed rate. Advances under the program had a one-year term and were priced at the overnight index swap ("OIS") rate plus 10 basis points on the day the advance was made. Effective January 24, 2024, the FRB announced that future advances through the program’s expiration on March 11, 2024, would be set at no lower than the interest rate on reserve balances in effect at the time of the advance. At December 31, 2025, we had pledged investment securities with an amortized cost of $312.9 million and a fair value of $293.9 million as collateral for FRB borrowings. Depository institutions may borrow from the FRB's discount window for periods as long as 90 days, and borrowings are prepayable and renewable by the borrower daily.

During 2023, the Company entered the FRB’s Borrower-In-Custody ("BIC") program. As of December 31, 2025, the Company had pledged loan collateral for FRB borrowings with an amortized cost and collateral value of $71.2 million and $57.4 million compared to pledged loan collateral with an amortized cost and collateral value of $84.9 million and $66.2 million at December 31, 2024, respectively. Borrowing capacity provided by pledged loan collateral is included in the FRB discount window availability.

As a member of the FHLB of Atlanta, the Bank is required to own capital stock in the FHLB of Atlanta and is authorized to apply for advances from the FHLB of Atlanta. Each FHLB credit program has its own interest rate, which may be fixed or variable, and range of maturities. The FHLB of Atlanta may prescribe the acceptable uses to which these advances may be utilized as well as limitations on the size of the advances and repayment provisions. At December 31, 2025, the Bank had no outstanding advances from the FHLB of Atlanta with remaining credit availability of $463.9 million, subject to collateral requirements.

At December 31, 2025, the Bank had $25.3 million in other borrowings consisting of retail repurchase agreements with an average rate of 1.49%.

For additional information regarding our borrowings, see "Note 10 - FHLB Advances and FRB Borrowings" and “Note 11 - Other Borrowings” in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K. See also, "Regulation - Regulation of the Bank - Federal Home Loan Bank System" in this 2025 Form 10-K.

On December 15, 2025, the Company redeemed all of its outstanding Floating Rate Junior Subordinated Deferrable Interest Debentures (the "Debentures") in accordance with the Indenture dated September 21, 2006. The Debentures were redeemed at 100% of the principal amount, plus accrued and unpaid interest to, but excluding, the redemption date. The $5.2 million principal payment reduced the junior subordinated debentures balance to $0, and accrued interest of $78,000 was recognized. No gain or loss was recorded on the redemption. Prior to redemption, the Debentures accrued and paid distributions quarterly at a floating rate equal to the three-month Secured Overnight Financing Rate ("SOFR") plus the relevant spread adjustment of 0.26161 plus 170 basis points, resulting in a rate of 6.00% on the redemption date. The Debentures were callable by the Company beginning in September 2011, and quarterly thereafter, with a final maturity date of December 15, 2036. See "Note 12 - Junior Subordinated Debentures" of the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

On November 22, 2019, the Company sold and issued to certain institutional investors $17.5 million in aggregate principal amount of 5.25% fixed-to-floating rate subordinated notes due 2029 (the “10-Year Notes”) and $12.5 million in aggregate principal amount of 5.25% fixed-to-floating rate subordinated notes due 2034 (the “15-Year Notes,” and together with the 10-Year Notes, the “Notes”). The Notes are unsecured, subordinated obligations of the Company, ranking junior in right of payment to the Company’s current and future senior indebtedness, and each Note is equal in right of payment with respect to the other Notes.

On November 22, 2024, the Company redeemed all remaining 10-Year Notes, with an aggregate principal balance of $16.5 million, at 100% of principal plus accrued and unpaid interest to, but excluding, the redemption date. The redemption was funded with excess cash on hand. The Company may redeem the 15-Year Notes, in whole or in part, at its option after November 22, 2029. See "Note 13 – Subordinated Debentures" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

Competition

The Bank serves the counties of Aiken, Lexington, Richland and Saluda, South Carolina, and the counties of Columbia and Richmond, Georgia through its 19 full service branch offices located in Aiken, Ballentine, Clearwater, Columbia, Graniteville, Langley, Lexington, North Augusta, Ridge Spring, Wagener, and West Columbia, South Carolina, and Augusta and Evans, Georgia.

Security Federal faces strong competition both in originating loans and in attracting deposits. Competition in originating loans comes primarily from other commercial banks, federal savings institutions, mortgage bankers and credit unions who also make loans in the Bank's market area, and more recently, financial technology (or “FinTech”) companies.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

The Bank competes for loans principally on the basis of the interest rates and loan fees it charges, the types of loans it makes and the quality of services it provides to borrowers. The Bank faces substantial competition in attracting deposits from federal savings institutions, commercial banks, money market and mutual funds, credit unions and other investment vehicles.

The ability of the Bank to attract and retain deposits depends on its ability to provide an investment opportunity that satisfies the requirements of investors as to rate of return, liquidity, risk and other factors. The Bank attracts a significant amount of deposits through its branch offices primarily from the communities in which those branch offices are located. Therefore, competition for those deposits is principally from federal savings institutions, credit unions and commercial banks located in the same communities. FinTech companies also compete for consumer deposit relationships. The Bank competes for these deposits by offering a variety of deposit accounts at competitive rates, convenient business hours, online/mobile services, and convenient branch locations with interbranch deposit and withdrawal privileges at each.

Human Capital

We continually strive to recruit the most talented, motivated employees in their respective fields. By providing opportunities for personal and professional growth coupled with an environment that values teamwork and work-life balance, we are able to attract and retain outstanding individuals. We pride ourselves on providing excellent benefits, competitive salaries and the opportunity for participation in our long-term success.

At December 31, 2025, we employed 258 employees. Our employees are not represented by any collective bargaining agreement.

REGULATION

The following is a brief description of certain laws and regulations which are applicable to the Company and the Bank. Descriptions of laws and regulations here and elsewhere in this 2025 Form 10-K do not purport to be complete and are qualified in their entirety by reference to the actual laws and regulations. Legislation is introduced from time to time in the United States Congress or in the South Carolina State Legislature that may affect the operations of the Company and the Bank. In addition, the regulations governing the Company and the Bank may be amended from time to time by the State Board, the FDIC, the Federal Reserve, the SEC and the Consumer Protection Financial Bureau (“CFPB”). Any such legislation or regulatory changes in the future could have an adverse effect on our operations and financial condition. We cannot predict whether any such changes may occur.

As a bank holding company, the Company is subject to examination and supervision by, and is required to file certain reports with, the Federal Reserve. The Company also is subject to the rules and regulations of the SEC under the federal securities laws. The Bank, as a state-chartered commercial bank, is subject to regulation and oversight by the State Board, the applicable provisions of South Carolina law and by the regulations of the State Board adopted thereunder. In some circumstances, the law and regulations of other states can apply. The Bank also is subject to regulation and examination by the FDIC, which insures its deposits to the maximum extent permitted by law.

Regulation of the Bank

The Bank is an FDIC-insured, state-chartered, non-member, commercial bank and is subject to various statutory requirements and rules and regulations promulgated and enforced primarily by the FDIC and the State Board. These statutes, rules, and regulations relate to insurance of deposits, required reserves, allowable investments, loans, mergers, consolidations, issuance of securities, payment of dividends, establishment of branches and other aspects of the business of the Bank. The FDIC has broad authority to prohibit the Bank from engaging in what it determines to be unsafe or unsound banking practices. In addition, federal law imposes a number of restrictions on state-chartered, FDIC-insured banks, and their subsidiaries. These restrictions cover many matters, examples of which include prohibitions against engaging as a principal in certain activities and the requirement of prior notification of branch closings. The Bank is required to file periodic reports with the FDIC and the State Board and is subject to periodic examinations and evaluations by those regulatory authorities. Based on these evaluations, the regulators may revalue the assets of an institution and require that it establish specific reserves to compensate for the differences between the determined value and the book value of these assets. The FDIC and the State Board may each accept the results of an examination by the other in lieu of conducting an independent examination.

Deposit Insurance and Other FDIC Programs

The Deposit Insurance Fund ("DIF") of the FDIC insures deposits in the Bank up to $250,000 per separately insured deposit ownership right or category and such insurance is backed by the full faith and credit of the United States Government. As insurer, the FDIC imposes deposit insurance premiums (assessments) and is authorized to conduct examinations of and to require reporting by FDIC-insured institutions. In October 2022, the FDIC adopted a final rule to increase initial base deposit insurance assessment rates by two basis points beginning in the first quarterly assessment period of 2023. A significant increase in insurance premiums or a special assessment levied by the FDIC could likely have an adverse effect on the operating expenses and results of operations of the Bank. There can be no prediction as to what changes in insurance assessment rates may be made in the future. For the year ended December 31, 2025, the Bank paid $718,000 in FDIC premiums. The FDIC assesses deposit insurance premiums quarterly on each FDIC-insured institution applied to its deposit base, which is its average consolidated total assets minus its Tier 1 capital. No institution may pay a dividend if it is in default on its federal deposit insurance assessment. At December 31, 2025, total base assessment rates ranged from 2.5 to 32 basis points subject to certain adjustments.

The FDIC may terminate the deposit insurance of any insured depository institution if it determines after a hearing that the institution has engaged or is engaging in unsafe or unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, order or any condition imposed by an agreement with the FDIC. It also may suspend deposit insurance temporarily during the hearing process for the permanent termination of insurance if the institution has no tangible capital. If insurance of accounts is terminated, the accounts at the institution at the time of the termination, less subsequent withdrawals, shall continue to be insured for a period of six months to two years, as determined by the FDIC. Management is not aware of any existing circumstances which would result in termination of the Bank's deposit insurance. A significant increase in insurance premiums would likely have an adverse effect on the operating expenses and results of operations of the Bank. There can be no prediction as to what changes in insurance assessment rates may be made in the future.

Prompt Corrective Action

Federal statutes establish a supervisory framework based on five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. An institution's category depends upon where its capital levels are in relation to relevant capital measures, which include risk-based capital measures, a common equity Tier 1 ("CET1") measure, a leverage ratio measure and certain other factors. The well-capitalized category is described below in "Capital Requirements". An institution that is not well capitalized is subject to certain restrictions on brokered deposits, including restrictions on the rates it can offer on its deposits, generally. Any institution which is neither well capitalized nor adequately capitalized is considered undercapitalized. Undercapitalized institutions are subject to certain prompt corrective action requirements, regulatory controls and restrictions that become more extensive as an institution becomes more severely undercapitalized. Failure by institutions to comply with applicable capital requirements would, if unremedied, result in progressively more severe restrictions on their activities and lead to enforcement actions, including, but not limited to, the issuance of a capital directive to ensure the maintenance of required capital levels and, ultimately, the appointment of the FDIC as receiver or conservator. Banking regulators will take prompt corrective action with respect to depository institutions that do not meet minimum capital requirements. Additionally, approval of any regulatory application filed for review by the banking agencies may be dependent on compliance with capital requirements.

At December 31, 2025, the Bank was categorized as "well capitalized" under the prompt corrective action regulations of the FDIC. For additional information, see "Capital Requirements" below and "Note 15 - Regulatory Matters" in the Notes to Consolidated Financial Statements included in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Capital Requirements

The Bank is subject to capital regulations adopted by the FDIC, which establish minimum required ratios for a common equity Tier 1 (“CET1”) capital to risk-based assets ratio, a Tier 1 capital to risk-based assets ratio, a total capital to risk-based assets ratio and a Tier 1 capital to total assets leverage ratio. The capital standards require the maintenance of the following minimum capital ratios: (i) a CET1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6%; (iii) a total capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. Consolidated regulatory capital requirements identical to those applicable to subsidiary banks generally apply to bank holding companies. However, the Federal Reserve Board has provided a “Small Bank Holding Company” exception to its consolidated capital requirements, and bank holding companies with less than $3.0 billion of consolidated assets are not subject to the consolidated holding company capital requirements unless otherwise directed by the Federal Reserve Board.

Federal law required the federal banking agencies, including the FDIC, to establish a “community bank leverage ratio” of between 8% and 10% for institutions with total consolidated assets of less than $10 billion. Institutions with capital complying with the ratio and otherwise meeting the specified requirements and electing the alternative framework are considered to comply with the applicable regulatory capital requirements, including the risk-based requirements. The community bank leverage ratio was established at 9% Tier 1 capital to total average assets, effective January 1, 2022. A qualifying institution may opt in and out of the community bank leverage ratio framework on its quarterly call report. The Bank has opted out of the community bank leverage ratio.

In addition to the minimum CET1, Tier 1, and total capital ratios, the capital regulations require a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses. To be considered “well capitalized,” a depository institution must have a Tier 1 risk-based capital ratio of at least 8%, a total risk-based capital ratio of at least 10%, a CET1 capital ratio of at least 6.5% and a leverage ratio of at least 5%, and not be subject to an individualized order, directive or agreement under which its primary federal banking regulator requires it to maintain a specific capital level. As of December 31, 2025, the Bank met the requirements to be “well capitalized” and met the fully phased-in capital conservation buffer requirement.

Federal Home Loan Bank System

The Bank is a member of the FHLB of Atlanta, which is one of 11 regional FHLBs that administer the home financing credit function of financial institutions. The FHLBs are subject to the oversight of the Federal Housing Finance Agency and each FHLB serves as a reserve or central bank for its members within its assigned region. The FHLBs are funded primarily from proceeds derived from the sale of consolidated obligations of the FHLB System and make loans or advances to members in accordance with policies and procedures established by the Board of Directors of the FHLB, which are subject to the oversight of the Federal Housing Finance Board. All advances from the FHLB of Atlanta are required to be fully secured by sufficient collateral as determined by the FHLB of Atlanta. In addition, all long-term advances are required to provide funds for residential home financing. At December 31, 2025, the Bank had no outstanding advances from the FHLB of Atlanta under an available credit facility of $463.9 million, which is limited to available collateral. See "Business - Sources of Funds - Borrowings."

As a member, the Bank is required to purchase and maintain stock in the FHLB of Atlanta. At December 31, 2025, the Bank had $1.1 million in FHLB of Atlanta stock, which was in compliance with this requirement. In past years, the Bank has received dividends on its FHLB of Atlanta stock. These dividend yields averaged 6.61% for the year ended December 31, 2025 and 7.35% for the year ended December 31, 2024.

The FHLBs continue to contribute to low- and moderately-priced housing programs through direct loans or interest subsidies on advances targeted for community investment and low- and moderate-income housing projects. These contributions have in the past affected adversely the level of FHLB dividends paid and could continue to do so in the future. These contributions could also have an adverse effect on the value of FHLB of Atlanta stock in the future. A reduction in value of the Bank's FHLB of Atlanta stock may result in a decrease in net income and possibly the Bank's capital.

Affiliate Transactions

The Company and the Bank are separate and distinct legal entities. Federal laws strictly limit the ability of banks to engage in certain transactions with their affiliates, including their bank holding companies. Transactions deemed to be "covered transactions" under Section 23A of the Federal Reserve Act and between a subsidiary bank and its parent company or the nonbank subsidiaries of the bank holding company are limited to 10% of the bank subsidiary's capital and surplus and, with respect to the parent company and all such nonbank subsidiaries, to an aggregate of 20% of the bank subsidiary's capital and surplus. Further, covered transactions that are loans and extensions of credit generally are required to be secured by eligible collateral in specified amounts. Federal law also requires that covered transactions and certain other transactions listed in Section 23B of the Federal Reserve Act between a bank and its affiliates be on terms as favorable to the bank as transactions with non-affiliates.

Community Reinvestment Act

The Bank is also subject to the provisions of the Community Reinvestment Act of 1977 ("CRA"), which requires the appropriate federal bank regulatory agency to assess a bank’s performance under the CRA in meeting the credit needs of the community serviced by the Bank, including low and moderate income neighborhoods. The regulatory agency's assessment of a bank's record is made available to the public. Further, a bank’s CRA performance rating must be considered in connection with a bank’s application to, among other things, establish a new branch office that will accept deposits, relocate an existing office or merge or consolidate with, or acquire the assets or assume the liabilities of, a federally regulated financial institution, and in connection with certain applications by a bank holding company, such as bank acquisitions. The Bank received a "satisfactory" rating during its most recent CRA examination.

On October 24, 2023, federal banking agencies, including the FDIC, issued a final rule to strengthen and modernize CRA regulations. The final rule was published with an April 1, 2024, effective date and staggered compliance dates; however, implementation of the 2023 final rule was stayed by a preliminary injunction. In 2025, the federal banking agencies issued a Joint Notice of Proposed Rulemaking to rescind the 2023 final rule and reinstate the prior CRA regulations. As a result, the Bank will continue to be evaluated under the pre-2023 CRA regulatory framework.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Dividends

Dividends from the Bank constitute the major source of funds for dividends which may be paid by the Company to shareholders. The amount of dividends payable by the Bank to the Company depends upon the Bank's earnings and capital position, and is limited by federal and state laws, regulations and policies, including the capital conservation buffer requirement discussed above. South Carolina banking regulations restrict the amount of dividends that the Bank can pay to the Company, and may require prior approval before declaration and payment of any excess dividend.

The amount of dividends actually paid during any one period will be strongly affected by the Bank's management policy of maintaining a strong capital position. Federal law further provides that no insured depository institution may pay a cash dividend if it would cause the institution to be "undercapitalized," as defined in the prompt corrective action regulations. Moreover, the federal bank regulatory agencies also have the general authority to limit the dividends paid by insured banks if such payments should be deemed to constitute an unsafe and unsound practice.

Activities and Investments of Insured State-Chartered Financial Institutions

Federal law generally limits the activities and equity investments of FDIC-insured, state-chartered banks to those that are permissible for national banks. An insured state bank is not prohibited from, among other things, (i) acquiring or retaining a majority interest in a subsidiary, (ii) investing as a limited partner in a partnership the sole purpose of which is direct or indirect investment in the acquisition, rehabilitation or new construction of a qualified housing project, provided that such limited partnership investments may not exceed 2% of the bank's total assets, (iii) acquiring up to 10% of the voting stock of a company that solely provides or reinsures directors', trustees' and officers' liability insurance coverage or bankers' blanket bond group insurance coverage for insured depository institutions, (iv) acting as agent for a customer in many capacities, and (v) acquiring or retaining the voting shares of a depository institution if certain requirements are met.

Federal Reserve System

The Federal Reserve requires that all depository institutions maintain reserves on transaction accounts, primarily checking accounts. At December 31, 2025, the Bank was in compliance with the reserve requirements in place at that time.

Standards for Safety and Soundness

The federal banking regulatory agencies have prescribed, by regulation, guidelines for all insured depository institutions relating to internal controls, information systems and internal audit systems; loan documentation; credit underwriting; interest rate risk exposure; asset growth; asset quality; earnings; and compensation, fees and benefits. The guidelines set forth the safety and soundness standards that the federal banking agencies use to identify and address problems at insured depository institutions before capital becomes impaired. Each insured depository institution must implement a comprehensive written information security program that includes administrative, technical, and physical safeguards appropriate to the institution’s size and complexity and the nature and scope of its activities. The information security program must be designed to ensure the security and confidentiality of customer information, protect against any unanticipated threats or hazards to the security or integrity of such information, protect against unauthorized access to or use of such information that could result in substantial harm or inconvenience to any customer, and ensure the proper disposal of customer and consumer information. Each insured depository institution must also develop and implement a risk-based response program to address incidents of unauthorized access to customer information in customer information systems. If the FDIC determines that an institution fails to meet any of these guidelines, it may require an institution to submit to the FDIC an acceptable plan to achieve compliance. Management of the Bank is not aware of any conditions relating to these safety and soundness standards which would require submission of a plan of compliance.

Environmental Issues Associated with Real Estate Lending

The Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), a federal statute, generally imposes strict liability on all prior and present "owners and operators" of sites containing hazardous waste. However, Congress acted to protect secured creditors by providing that the term "owner and operator" excludes a person whose ownership is limited to protecting its security interest in the site. Since the enactment of the CERCLA, this "secured creditor exemption" has been the subject of judicial interpretations which have left open the possibility that lenders could be liable for cleanup costs on contaminated property that they hold as collateral for a loan. To the extent that legal uncertainty exists in this area, all creditors, including the Bank, that have made loans secured by properties with potentially hazardous waste contamination (such as petroleum contamination) could be subject to liability for cleanup costs, which costs often substantially exceed the value of the collateral property.

Privacy Standards and Cybersecurity

The Bank is subject to FDIC regulations implementing the privacy protection provisions of the Gramm-Leach-Bliley Financial Services Modernization Act of 1999. These regulations require the Bank to disclose its privacy policy, including informing consumers of its information sharing practices and informing consumers of their rights to opt out of certain practices. In addition, the federal banking agencies recently adopted rules providing for new notification requirements for banking organizations and their service providers for significant cybersecurity incidents. Specifically, the new rules require a banking organization to notify its primary federal regulator as soon as possible, and no later than 36 hours after, the banking organization determines that a “computer-security incident” rising to the level of a “notification incident” has occurred. Notification is required for incidents that have materially affected or are reasonably likely to materially affect the viability of a banking organization’s operations, its ability to deliver banking products and services, or the stability of the financial sector. Service providers are required under the rule to notify affected banking organization customers as soon as possible when the provider determines that it has experienced a computer-security incident that has materially affected or is reasonably likely to materially affect the banking organization’s customers for four or more hours.

In July 2023, the SEC adopted rules requiring registrants to disclose material cybersecurity incidents they experience and to disclose on an annual basis material information regarding their cybersecurity risk management, strategy, and governance. The new rules require registrants to disclose on Form 8-K any cybersecurity incident they determine to be material and to describe the material aspects of the incident's nature, scope, and timing, as well as its material impact or reasonably likely material impact on the registrant. For information regarding the Company’s cybersecurity risk management, strategy and governance, see “Item 1C. Cybersecurity” contained in Part I of this 2025 Form 10-K.

Bank Secrecy Act / Anti-Money Laundering Laws

The Bank is subject to the Bank Secrecy Act and other anti-money laundering laws and regulations, including the USA PATRIOT Act of 2001. These laws and regulations require the Bank to implement policies, procedures, and controls to detect, prevent, and report money laundering and terrorist financing and to verify the identity of their customers. Violations of these requirements can result in substantial civil and criminal sanctions. In addition, provisions of the USA PATRIOT Act require financial institutions to establish procedures for identifying and verifying the identity of customers seeking to open new financial accounts, and effective in 2018, the beneficial owners of accounts. The federal financial institution regulatory agencies are directed to consider the effectiveness of a financial institution’s anti-money laundering activities when reviewing mergers and acquisitions.

Other Consumer Protection Laws and Regulations

The Dodd-Frank Act established the CFPB and empowered it to exercise broad regulatory, supervisory and enforcement authority with respect to both new and existing consumer financial protection laws. The Bank is subject to consumer protection regulations issued by the CFPB, but as a financial institution with assets of less than $10 billion, the Bank is generally subject to supervision and enforcement by the FDIC and the State Board with respect to our compliance with federal and state consumer financial protection laws and regulations.

The Bank is subject to a broad array of federal and state consumer protection laws and regulations that govern almost every aspect of its business relationships with consumers. While the list set forth below is not exhaustive, these include the Truth-in-Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, the Equal Credit Opportunity Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Home Mortgage Disclosure Act, the Fair Credit Reporting Act, the Fair Debt Collection Practices Act, the Right to Financial Privacy Act, the Home Ownership and Equity Protection Act, the Consumer Leasing Act, the Fair Credit Billing Act, the Homeowners Protection Act, the Check Clearing for the 21st Century Act, laws governing flood insurance, laws governing consumer protections in connection with the sale of insurance, federal and state laws prohibiting unfair and deceptive business practices, and various regulations that implement some or all of the foregoing. These laws and regulations mandate certain disclosure requirements and regulate the manner in which financial institutions must deal with customers when taking deposits, making loans, collecting loans, and providing other services. Failure to comply with these laws and regulations can subject the Bank to various penalties, including but not limited to, enforcement actions, injunctions, fines, civil liability, criminal penalties, punitive damages, and the loss of certain contractual rights.

Regulation of the Company

The Company, as the sole shareholder of the Bank, is a registered bank holding company with the Federal Reserve. Bank holding companies are subject to comprehensive regulation by the Federal Reserve under the Bank Holding Company Act of 1956, as amended ("BHCA"), and the regulations promulgated thereunder. This regulation and oversight is generally intended to ensure that the Company limits its activities to those allowed by law and that it operates in a safe and sound manner without endangering the financial health of the Bank.

As a bank holding company, the Company is required to file with the Federal Reserve semi-annual and periodic reports and such additional information as the Federal Reserve may require and is subject to regular examinations by the Federal Reserve. The Federal Reserve may examine the Company, and any of its subsidiaries, and charge the Company for the cost of the examination. The Federal Reserve also has extensive enforcement authority over bank holding companies, including, among other things, the ability to assess civil money penalties, to issue cease and desist or removal orders and to require that a holding company divest subsidiaries (including its bank subsidiaries). In general, enforcement actions may be initiated for violations of law and regulations and unsafe or unsound practices.

The Bank Holding Company Act

Under the BHCA, the Company is supervised by the Federal Reserve. The Federal Reserve has a policy that a bank holding company is required to serve as a source of financial and managerial strength to its subsidiary banks and may not conduct its operations in an unsafe or unsound manner. In addition, the Dodd-Frank Act and earlier Federal Reserve policy provide that a bank holding company should serve as a source of strength to its subsidiary bank by having the ability to provide financial assistance to its subsidiary bank during periods of financial distress to the bank, and should maintain the financial flexibility and capital raising capacity to obtain additional resources for assisting its subsidiary bank. A bank holding company's failure to meet its obligation to serve as a source of strength to its subsidiary banks will generally be considered by the Federal Reserve to be an unsafe and unsound banking practice or a violation of the Federal Reserve's regulations or both. No regulations have yet been proposed by the Federal Reserve to implement the source of strength provisions of the Dodd-Frank Act. The Company and any subsidiaries that it may control are considered "affiliates" within the meaning of the Federal Reserve Act, and transactions between the Bank and affiliates (except subsidiaries of the Bank) are subject to numerous restrictions. With some exceptions, the Company and its subsidiaries, are prohibited from tying the provision of various services, such as extensions of credit, to other services offered by the Company, or by its affiliates.

Acquisitions

The BHCA prohibits a bank holding company, with certain exceptions, from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank or bank holding company and from engaging directly or indirectly in activities other than those of banking, managing or controlling banks, or providing services for its subsidiaries. Under the BHCA, the Federal Reserve is authorized to approve the ownership of shares by a bank holding company in any company, the activities of which the Federal Reserve has determined to be so closely related to the business of banking or managing or controlling banks as to be a proper incident thereto. The list of activities determined by regulation to be closely related to banking within the meaning of the BHCA includes, among other things: operating a savings institution, mortgage company, finance company, credit card company or factoring company; performing certain data processing operations; providing certain investment and financial advice; underwriting and acting as an insurance agent for certain types of credit-related insurance; leasing property on a full-payout, non-operating basis; selling money orders, travelers' checks and U.S. Savings Bonds; real estate and personal property appraising; providing tax planning and preparation services; and, subject to certain limitations, providing securities brokerage services for customers. The Federal Reserve must approve the acquisition (or acquisition of control) of a bank or other FDIC-insured depository institution by a bank holding company, and the appropriate federal banking regulator must approve a bank’s acquisition (or acquisition of control) of another bank or other FDIC-insured institution.

Capital Requirements

As discussed above, bank holding companies with less than $3.0 billion in consolidated assets are generally no longer subject to the Federal Reserve’s capital regulations, which are essentially the same as the capital regulations applicable to the Bank described under the caption “Capital Requirements” above. If the Company were subject to regulatory guidelines for bank holding companies with $3.0 billion or more in assets at December 31, 2025, the Company would have exceeded all regulatory requirements. The Federal Reserve expects a holding company's subsidiary banks to be well capitalized under the prompt corrective action regulations. For additional information, see "Note 15 - Regulatory Matters" of the Notes to Consolidated Financial Statements included in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Dividends

As a South Carolina corporation, the Company is subject to restrictions on the payment of dividends under South Carolina law. In addition, the Company is an entity separate and distinct from its principal subsidiary, Security Federal Bank, and derives substantially all of its revenue in the form of dividends from this subsidiary. Accordingly, the Company is, and will be, dependent upon dividends from the Bank to pay the principal of and interest on its indebtedness, to satisfy its other cash needs and to pay dividends on its common stock. The Company is also subject to certain federal regulatory considerations. The Federal Reserve has issued a policy statement on the payment of cash dividends by bank holding companies, which expresses the Federal Reserve's view that a bank holding company should pay cash dividends only to the extent that the company's net income for the past year is sufficient to cover both the cash dividends and a rate of earnings retention that is consistent with the company's capital needs, asset quality and overall financial condition, and that it is inappropriate for a company experiencing serious financial problems to borrow funds to pay dividends. Dividends are also subject to restriction if the capital conservation buffer requirement is not met.

Stock Repurchases

Bank holding companies, except for certain "well-capitalized" and highly rated bank holding companies, are required to give the Federal Reserve prior written notice of any purchase or redemption of its outstanding equity securities if the consideration for the purchase or redemption, when combined with the net consideration paid for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of their consolidated net worth. The Federal Reserve may disapprove a purchase or redemption if it determines that the proposal would constitute an unsafe or unsound practice or would violate any law, regulation, Federal Reserve order, or any condition imposed by, or written agreement with, the Federal Reserve.

TAXATION

Federal Taxation

The Company and the Bank report their income on a calendar year basis using the accrual method of accounting and are subject to federal income taxation in the same manner as other corporations with some exceptions, including particularly the Bank's reserve for bad debts discussed below. The following discussion of tax matters is intended only to summarize certain pertinent federal income tax matters and is not a comprehensive description of the tax rules applicable to the Bank or the Company.

To the extent that the Bank makes "nondividend distributions" to the Company, these distributions will be considered to result in distributions from the balance of its bad debt reserve as of December 31, 1987 (or a lesser amount if the Bank's loan portfolio decreased since December 31, 1987) and then from the supplemental reserve for losses on loans ("Excess Distributions"), and an amount based on the Excess Distributions will be included in the Bank's taxable income. Nondividend distributions include distributions in excess of the Bank's current and accumulated earnings and profits, distributions in redemption of stock and distributions in partial or complete liquidation. However, dividends paid out of the Bank's current or accumulated earnings and profits, as calculated for federal income tax purposes, will not be considered to result in a distribution from the Bank's bad debt reserve. The amount of additional taxable income created from an Excess Distribution is an amount that, when reduced by the tax attributable to the income, is equal to the amount of the distribution. Thus, if the Bank makes a "nondividend distribution," then approximately one and one-half times the Excess Distribution would be includable in gross income for federal income tax purposes, assuming a 21% corporate income tax rate (exclusive of state and local taxes). See "Regulation - Regulation of the Bank - Dividends” for limits on the payment of dividends by the Bank. The Bank does not intend to pay dividends that would result in a recapture of any portion of its tax bad debt reserve.

The Company may carryforward net operating losses indefinitely. As of December 31, 2025, management determined it is more likely than not that the total deferred tax asset will be realized except for the deferred tax asset associated with state net operating loss carryforwards, and, accordingly, has established a valuation allowance only for this item. The change in the valuation allowance was approximately $159,000.

The Company may exclude from its income dividends received from the Bank as a wholly-owned subsidiary of the Company that files a consolidated return with the Bank. The corporate dividends-received deduction is 100%, or 80%, in the case of dividends received from corporations with which a corporate recipient does not file a consolidated tax return, depending on the level of stock ownership of the payer of the dividend. Corporations that own less than 20% of the stock of a corporation distributing a dividend may deduct 70% of dividends received or accrued on their behalf.

The Company, the Bank and its consolidated subsidiaries have been audited or their books closed without audit by the IRS with respect to consolidated federal income tax returns through December 31, 2024. For additional information regarding income taxes, see "Note 14 - Income Taxes" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

State Taxation

South Carolina has adopted the Internal Revenue Code as it relates to commercial banks, effective for taxable years beginning after December 31, 1986. The Bank is subject to South Carolina income tax at the rate of 4.5%. The Bank has not been audited by the State of South Carolina during the past five years. The Company's income tax returns have not been audited by federal or state authorities within the last five years. For additional information regarding income taxes, see "Note 14 - Income Taxes" in the Notes to Consolidated Financial Statements contained in “Item 8. Financial Statements and Supplementary Data” of this 2025 Form 10-K.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Item 1A. Risk Factors.

An investment in our common stock involves various risks which are particular to Security Federal Corporation, our industry, and our market area. Before making an investment decision, you should carefully consider the risks and uncertainties described below, together with all the other information included in this report and our other documents filed with and furnished to the SEC. In addition to the risks and uncertainties described below, other risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition, capital levels, liquidity, cash flows, results of operations and prospects. The market price of our common stock could decline significantly due to any of these identified or other risks, and you could lose some or all your investment.

Risks Related to Deregistration

Deregistration may reduce liquidity, marketability, and investor access to information about the Company.

The Company’s securities are no longer registered under the Securities Exchange Act of 1934, and the Company’s reporting obligations were suspended upon the filing of a Form 15 with the SEC on December 12, 2025. The Company’s common stock continues to trade on the OTCID Basic Market. As a result, publicly available information about the Company will be limited, and the liquidity and marketability of the Company’s securities may be reduced, which may make it more difficult for investors to buy, sell, or obtain information about the Company.

Risks Related to Macroeconomic Conditions

Our business may be adversely affected by downturns in the national economy and in the economies in our market areas.

Our operations are significantly affected by the general economic conditions of the states of South Carolina and Georgia and the specific local markets in which we operate. Our entire real estate portfolio consists primarily of loans secured by properties located in Aiken, Richland, and Lexington Counties in South Carolina and Columbia and Richmond Counties in Georgia. Adverse economic conditions in our market areas could impact our growth rate, reduce our customers’ ability to repay loans, and adversely impact our business, financial condition, and results of operations. Broad economic factors such as inflation, unemployment and money supply fluctuations also may adversely affect our profitability. Trade wars, tariffs, or shifts in trade policies between the United States and other nations could disrupt supply chains, increase costs for businesses, and reduce export opportunities for our customers. These developments may, in turn, negatively impact these businesses and, by extension, our operations and financial performance.

A deterioration in economic conditions in the market areas we serve, due to inflation, a recession, war, geopolitical conflicts, adverse weather conditions, or other factors could result in the following consequences, any of which, could have a materially adverse effect on our business, financial condition, or results of operations:

•

Elevated instances of loan delinquencies, problematic assets, and foreclosures.

•

An increase in our allowance for credit losses on loans;

•

Reduced demand for our products and services, potentially leading to a decline in our overall loans or assets.

•

Depreciation in collateral values linked to our loans, thereby diminishing borrowing capacities and asset values tied to existing loans.

•

Reduced net worth and liquidity of loan guarantors, possibly impairing their ability to meet commitments to us.

•

Reduction in our low-cost or noninterest-bearing deposits.

A decline in local economic conditions may have a greater effect on our earnings and capital than on the earnings and capital of larger financial institutions whose real estate loan portfolios are geographically diverse. Many of the loans in our portfolio are secured by real estate. Any deterioration in the real estate markets associated with the collateral securing mortgage loans could significantly impact borrowers' repayment capabilities and the value of collateral. Real estate values are affected by various factors, including economic conditions, governmental rules or policies, natural disasters such as earthquakes, and trade-related pressures that may affect construction costs or materials availability. If we are required to liquidate a significant amount of collateral during a period of reduced real estate values, our financial condition and profitability could be adversely affected.

Monetary policy, inflation, deflation, and other external economic factors could adversely impact our business, financial condition and results of operations.

Our financial condition and results of operations are influenced by monetary, fiscal, and trade policies, including those of the Federal Reserve, the U.S. Treasury, and other governmental authorities. Actions by these authorities may lead to inflation, deflation, changes in interest rates, or other economic conditions that could materially adversely affect our results of operations. Tariffs, supply-chain disruptions, or rising costs could reduce the ability of our clients, particularly small- and medium-sized businesses, to repay loans, negatively affecting credit quality and financial performance. Prolonged inflation may increase operational costs, including wages and benefits, while fluctuations in interest rates and the yield curve can significantly impact our net interest income. Interest rates may not move in alignment with inflation or deflation, adding uncertainty to the economic environment.

Risks Related to Our Lending Activities

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

Lending money is a substantial part of our business, and each loan carries risks related to potential non-repayment or insufficient collateral to guarantee repayment. Various factors contribute to this risk, including:

•

The cash flow generated by the borrower or the project being financed.

•

Uncertainties and fluctuations in the future value of collateral for secured loans.

•

The duration or term of the loan.

•

The individual characteristics and creditworthiness of a borrower.

•

Changes in economic and industry conditions over time.

Table of Contents

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

We maintain an allowance for credit losses on loans, which is a reserve established through a provision for credit losses charged to expense. This allowance is intended to cover lifetime expected credit losses in our loan portfolio. The appropriate level of the allowance is determined by management through periodic reviews and consideration of several factors, including, but not limited to:

•

Collective loss reserve: Assessing loans on a pooled basis with comparable risk traits, drawing from our historical default and loss data, macroeconomic indicators, feasible forecasts, regulatory standards, management’s foresight into future events, and specific qualitative elements.

•

Individual loss reserve: Evaluating individual loans with distinct risk characteristics, weighing the present value of anticipated future cash flows or the fair value of the underlying collateral.

The determination of the appropriate level of the allowance for credit losses involves a high degree of subjectivity and requires significant estimates of current credit risks and future trends, which may change materially. If our estimates are incorrect, the allowance may not be sufficient to cover the expected losses in our loan portfolio, resulting in the need to increase the allowance through the provision for credit losses, recorded as a charge against income. Additionally, management recognizes that new growth in loan portfolios, new loan products, and the refinancing of existing loans can result in portfolios comprised of unseasoned loans, which may not perform as historically or projected. This increases the risk that the allowance may be insufficient to absorb losses without significant additional provisions. Our allowance for credit losses on loans was 1.97% of total loans outstanding (excluding loans held for sale) at December 31, 2025. For additional information concerning our allowance for credit losses, see “Management’s Discussion and Analysis of Financial Condition - Comparison of Results of Operations for the Years Ended December 31, 2025 and 2024 - Provision for Credit Losses” contained in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation” of this 2025 Form 10-K.

In addition, bank regulatory agencies periodically review our allowance for credit losses and may require us to increase our provision for credit losses or recognize additional loan charge-offs. Any increases in the provision for credit losses may result in a decrease in net income and may have a material adverse effect on our financial condition, results of operations and capital.

If our non-performing assets increase, our earnings will be adversely affected.

At December 31, 2025, our non-performing assets (which consist of non-accrual loans and other real estate owned ("OREO")) were $5.8 million, or 0.36% of total assets. Our non-performing assets adversely affect our net income in various ways:

•

Interest income is recorded solely on a cash basis for non-accrual loans and any non-performing investment securities.

•

No interest income is recorded for OREO.

•

Expected loan losses are accounted for through a current-period provision for credit losses.

•

Writing down property values within our OREO portfolio to mirror changing market values or recognizing other-than-temporary impairment on non-performing investment securities leads to increased non-interest expenses.

•

Legal fees related to resolving problematic assets, along with carrying costs like taxes, insurance, and maintenance fees for our OREO, increase non-interest expenses.

•

Active management involvement in resolving non-performing assets may divert attention from more profitable activities.

If additional borrowers become delinquent and we are unable to successfully manage our non-performing assets, our losses and troubled assets could increase significantly, which could have a material adverse effect on our financial condition and results of operations.

Our level of commercial real estate loans may expose us to increased lending risks.

W hile commercial real estate lending offers the potential for higher returns compared to single-family residential lending, it is more susceptible to fluctuations in regional and local economic conditions, presenting challenges in accurately predicting potential losses. Evaluating collateral and conducting financial statement analysis for these loans requires a more intricate approach during underwriting and continual assessment. At December 31, 2025 , we had $295.3 million of commercial real estate loans, representing 43.0% of our total loan portfolio.

Commercial real estate loans typically involve larger principal amounts than other types of lending, and some borrowers hold multiple loans with us. Consequently, adverse developments in a single loan or credit relationship can significantly increase our risk exposure compared to single-family residential loans. Repayment of these loans depends on income generated or anticipated from the property securing the loan in amounts sufficient to cover operating expenses and debt service. Economic fluctuations or local market changes can impact this cash flow. For instance, failure to secure or renew leases can impair the borrower's ability to repay the loan. Commercial real estate loans also pose a greater credit risk than one-to-four family residential real estate loans, primarily because the collateral is less liquid. Further, many of these loans include large balloon payments upon maturity, increasing the risk of default as borrowers may need to sell or refinance the property to pay off the loan.

Unlike residential loans, a secondary market for most types of commercial real estate loans is not readily available, limiting our ability to mitigate credit risk by selling our interest. Foreclosing on these loans often entails longer holding periods due to fewer potential purchasers for the collateral. Consequently, charge-offs on commercial real estate loans may be comparatively higher on a per-loan basis than those in our residential or consumer loan portfolios.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Our construction real estate loans are based upon estimates of costs and the value of the completed project.

We originate construction loans for single-family residences, multi-family dwellings and projects, and commercial real estate, as well as loans for the acquisition and development and construction of residential subdivisions and commercial projects. At December 31, 2025, we had $66.6 million in construction loans, representing 9.7% of our total loan portfolio.

Construction lending involves inherent risks due to the need to estimate costs in relation to project values. Uncertainties in construction costs, market value fluctuations, and regulatory impacts make accurately evaluating total project funds and loan-to-value ratios challenging. Factors such as shifts in housing demand and unexpected building costs can significantly cause actual results to differ from estimates. Additionally, this type of lending often involves higher principal amounts and can be concentrated among a few builders. A downturn in housing or real estate markets could increase delinquencies, defaults, foreclosures, and reduce collateral values.

Some builders have multiple loans with our institution and also hold residential mortgage loans for rental properties with us. Consequently, an adverse development with one loan or credit relationship can expose us to a significantly greater risk of loss. Moreover, these loans often involve the disbursement of funds with repayment substantially dependent on the success of the project and borrower's ability to sell, lease, or secure permanent financing. Thus, repayment depends heavily on the project’s success rather than the borrower’s ability to directly repay principal and interest. Misjudging a project’s value could leave us with inadequate security and potential losses upon completion. Actively monitoring construction loans, through cost comparisons and on-site inspections, adds complexity and cost. Market interest rate hikes may also significantly impact construction loans, affecting end-purchaser borrowing costs and potentially reducing demand or the homeowner's ability to finance the completed home. Further, properties under construction are difficult to sell and often need completion to be sold successfully, complicating loan resolution. This might require additional funds or engaging another builder, which incurs further costs and market risks. Speculative construction loans, in particular, pose additional risks, especially in finding end-purchasers for finished projects.

Our construction loans include those with a sales contract or permanent loan in place for finished homes, as well as speculative construction loans, where purchasers for the finished homes may not be identified during or after the construction period. Speculative construction loans carry additional risks, particularly regarding the challenge of finding end-purchasers for completed projects. Land loans also present additional risks due to lack of income generated by the property and the potential illiquidity of the collateral. These risks can be significantly impacted by supply and demand conditions.

Construction, acquisition, and development ("A&D") loans carry additional risks due to the lack of income generated by the property and the potential illiquidity of the collateral. These risks are especially sensitive to supply and demand dynamics, significantly impacting this type of lending. Consequently, such loans often require substantial fund disbursements, where repayment depends on the project's success and the borrower's ability to develop, sell, or lease the property. This differs from the borrower's or guarantor's ability to independently repay principal and interest. At December 31, 2025, there were no non-performing A&D loans. However, a significant increase in non-performing construction and development loans could materially impact our financial condition and results of operations.

Repayment of our commercial and agricultural business loans is often dependent on the cash flows of the borrower, which may be unpredictable, and the collateral securing these loans may fluctuate in value.

At December 31, 2025, $37.9 million or 5.5% of our total loans were commercial and agricultural business loans. These loans carry distinct risks compared to residential and commercial real estate loans. Unlike real estate lending, which relies on predetermined loan-to-collateral values and views liquidation of the underlying real estate as the primary source of repayment in case of default, our commercial and agricultural business loans are primarily predicated on the borrower's cash flow and secondarily on provided collateral. The borrower's cash flow, often unpredictable, serves as the primary repayment source, supported by collateral such as equipment, inventory, or accounts receivable. However, relying solely on collateral in the event of default may be insufficient due to uncollectible receivables, obsolete inventory, or other factors.

Our real estate lending exposes us to the risk of environmental liabilities.

In the course of our business, we may foreclose on and take title to real estate, and we could be subject to environmental liabilities concerning these properties. We may be held liable by a governmental entity or third parties for property damage, personal injury, investigation, and clean-up costs incurred due to environmental contamination. We may also be required to investigate or clean up hazardous or toxic substances, or chemical releases, at a property. The costs associated with investigation or remediation activities could be substantial. In addition, as the owner or former owner of a contaminated site, we may be subject to common law claims by third parties for damages and costs resulting from environmental contamination emanating from the property. If we ever become subject to significant environmental liabilities, our business, financial condition, and results of operations could be materially and adversely affected.

If our investments in real estate are not properly valued or sufficiently reserved to cover actual losses, or if we are required to increase our valuation reserves, our earnings could be reduced.

We obtain updated valuations in the form of appraisals and broker price opinions when a loan has been foreclosed upon and the property is taken as OREO, as well as at certain other times during the asset's holding period. Our net book value of the loan at the time of foreclosure and thereafter is compared to the updated market value of the foreclosed property less estimated selling costs (fair value). A charge-off is recorded for any excess of the asset's net book value over its fair value. If our valuation process is incorrect, or if the property declines in value after foreclosure, the fair value of our investments in OREO may not be sufficient to recover our net book value in such assets, resulting in the need for additional charge-offs. Additional material charge-offs to our investments in OREO could have a materially adverse effect on our financial condition and results of operations. In addition, bank regulators periodically review our OREO and may require us to recognize further charge-offs. Significant charge-offs, as required by such regulators, may have a materially adverse effect on our financial condition and results of operations.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Our securities portfolio may be negatively impacted by fluctuations in market value, changes in the tax code, and interest rates.

Factors beyond our control can significantly influence the fair value of securities in our portfolio and may cause adverse changes to the fair value of these securities. These factors include, but are not limited to, rating agency actions regarding the securities, defaults by, or other adverse events affecting, the issuer or the underlying securities, and changes in market interest rates, as well as continued instability in the capital markets. Any of these factors, among others, could result in realized and/or unrealized losses in future periods and declines in other comprehensive income, which could materially affect on our business, financial condition and results of operations. The process for determining whether the decline in fair value is the result of credit losses or other factors requires complex, subjective judgments about the future financial performance and liquidity of the issuer and any collateral underlying the security to assess the probability of receiving all contractual principal and interest payments on the security. There can be no assurance that declines in market value will not result in credit losses on these assets, leading to accounting charges that could have a material adverse effect on our net income and capital levels. At December 31, 2025, there was no allowance for credit losses in our securities portfolio.

Risk Related to Changes in Market Interest Rates

Changes in interest rates may reduce our net interest income, and may result in higher defaults in a rising rate environment.

Our earnings and cash flows are largely dependent upon our net interest income, which is significantly affected by interest rates. Interest rates are highly sensitive to factors beyond our control, such as general economic conditions and policies set by governmental and regulatory bodies, particularly the Federal Reserve. Increases in interest rates could reduce our net interest income, weaken the housing market by curbing refinancing activity and home purchases, and negatively affect the broader U.S. economy, potentially leading to slower economic growth or recessionary conditions.

We principally manage interest rate risk by managing our volume and mix of our earning assets and funding liabilities. If we are unable to manage this risk effectively, our business, financial condition, and results of operations could be materially affected.

Our net interest margin, the difference between the yield on interest-earning assets and the cost of interest-bearing liabilities, can be adversely affected by interest rate changes. While yields on assets and costs of liabilities tend to move in the same direction, they may do so at different speeds, causing the margin to expand or contract. As our interest-bearing liabilities often have shorter durations than our interest-earning assets, a rise in interest rates may lead to funding costs increasing faster than asset yields, compressing our net interest margin. Additionally, changes in the slope of the yield curve, such as flattening or inversion, can further pressure our margins as funding costs rise relative to asset yields. Conversely, falling rates can increase loan prepayments, leading to reinvestment in lower-yielding assets, reducing income.

In a rising rate environment, retaining deposits can become costlier. If deposit and borrowing rates rise faster than loan and investment yields, our net interest income and overall earnings could decline. Additionally, adjustable-rate residential mortgage loans and home equity lines of credit may face increased default risks in a rising rate environment. Interest rate fluctuations also influence the fair value of fixed-rate investment securities, which inversely correlates with rate changes. At December 31, 2025, the fair value of our securities available for sale was $663.5 million, with unrealized net losses of $20.6 million reflected in stockholders’ equity. Further declines in fair value from rising rates could have an adverse effect on stockholders’ equity.

While we employ asset and liability management strategies to mitigate interest rate risk, unexpected, substantial, or prolonged rate changes could materially affect our financial condition and results of operations. Additionally, our interest rate risk models and assumptions may not fully capture the impact of actual rate changes on our balance sheet or projected operating results. For further details, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Asset and Liability Management and Market Risk” of this 2025 Form 10–K.

An increase in interest rates, change in the programs offered by governmental sponsored entities ("GSE"), or our ability to qualify for such programs may reduce our mortgage revenues, which would negatively impact our non-interest income.

Our mortgage banking operations contribute significantly to our noninterest income, primarily through gains on the sale of one-to-four-family real estate loans. These loans are sold pursuant to programs offered by Fannie Mae, which entity accounts for a substantial portion of the secondary market for such loans. Changes to these programs, our eligibility to participate, the criteria for loan acceptance, or related laws could materially and adversely affect our results of operations.

Mortgage banking is generally considered a volatile source of income because it depends largely on loan volume, which is influenced by prevailing market interest rates. In a rising or higher interest rate environment, our originations of mortgage loans may decrease, resulting in fewer loans that are available to be sold to investors. This would result in a decrease in mortgage banking revenues and a corresponding decrease in noninterest income.

Our results of operations are also affected by noninterest expenses associated with mortgage banking activities, including salaries and employee benefits, occupancy, equipment, data processing, and other operating costs. During periods of reduced loan demand, we may face challenges in reducing these expenses proportionately, which could adversely impact our results of operations. Although we sell loans into the secondary market without recourse, we provide customary representations and warranties to buyers. If these representations and warranties are breached, we may be required to repurchase the loans, potentially incurring a loss.

Risk Related to Regulatory and Compliance Matters

New or changing tax, accounting, and regulatory rules and interpretations could significantly impact strategic initiatives, results of operations, cash flows, and financial condition.

The financial services industry is extensively regulated. Federal and state banking regulations are designed primarily to protect the deposit insurance funds and consumers, not to benefit our shareholders. Regulations may sometimes impose significant limitations on operations. Regulatory authorities have extensive discretion in connection with their supervisory and enforcement activities, including the imposition of restrictions on an institution's operations, the classification of assets by the institution and the adequacy of an institution's allowance for credit losses. These bank regulators also have the ability to impose conditions in the approval of merger and acquisition transactions.

The significant federal and state banking regulations that affect us are described in this report under “Business - Regulation” in Item 1 of this 2025 Form 10-K. These regulations, along with the existing tax, accounting, securities, insurance, and monetary laws, regulations, rules, standards, policies and interpretations, control the methods by which financial institutions conduct business, implement strategic initiatives and tax compliance, and govern financial reporting and disclosures. These laws, regulations, rules, standards, policies, and interpretations are constantly evolving and may change significantly over time. Any new regulations or legislation or changes in existing regulations or oversight, whether a change in regulatory policy or a change in a regulator’s interpretation of a law or regulation, could have a material impact on our operations, increase our costs of regulatory compliance and of doing business and/or otherwise adversely affect us and our profitability. Additionally, actions by regulatory agencies or significant litigation against us and may lead to penalties that materially affect us. Further, changes in accounting standards can be both difficult to predict and involve judgment and discretion in their interpretation by us and our independent registered public accounting firm. These changes could materially impact, potentially even retroactively, how we report our financial condition and results of our operations as could our interpretation of those changes. We cannot predict what restrictions may be imposed upon us with future legislation.

Non-compliance with the USA PATRIOT Act, Bank Secrecy Act, or other laws and regulations could result in fines or sanctions.

The USA PATRIOT Act and Bank Secrecy Acts and related regulations require financial institutions to develop programs to prevent financial institutions from being used for money laundering and terrorist activities. If such activities are detected, financial institutions are obligated to file suspicious activity reports with the U.S. Treasury’s Office of Financial Crimes Enforcement Network. These rules require financial institutions to establish procedures for identifying and verifying the identity of customers seeking to open new financial accounts and beneficial owners of accounts. Failure to comply with these regulations could result in fines or sanctions. While we have developed policies and procedures designed to assist in compliance with these laws and regulations, no assurance can be given that these policies and procedures will be effective in preventing violations of these laws and regulations. If our policies and procedures are deemed deficient, we would be subject to liability, including fines and regulatory actions, which may include restrictions on our ability to pay dividends and the denial of regulatory approvals to proceed with certain aspects of our business plan, including acquisitions. Additionally, any perceived or actual failure to prevent money laundering or terrorist financing activities could significantly damage our reputation. These outcomes could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.

Our reported financial results depend on management’s selection of accounting methods and certain assumptions and estimates, which, if incorrect, could cause unexpected losses in the future.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. Management must exercise judgment in selecting and applying many of these accounting policies and methods so they comply with generally accepted accounting principles and reflect management’s judgment regarding the most appropriate manner to report our financial condition and results of operations. In some cases, management must select the accounting policy or method to apply from two or more alternatives, any of which might be reasonable under the circumstances, yet might result in us reporting materially different results than would have been reported under a different alternative.

Certain accounting policies are critical to presenting our financial condition and results of operations. They require management to make difficult, subjective or complex judgments about matters that are uncertain. Materially different amounts could be reported under different conditions or using different assumptions or estimates. These critical accounting policies include, but are not limited to the allowance for credit losses on loans, securities and unfunded commitments; the valuation of real estate acquired in connection with foreclosures or in satisfaction of loans; income taxes, including tax provisions and realization of deferred tax assets; and the fair value of assets and liabilities. Because of the uncertainty of estimates involved in these matters, we may be required, among other things, to significantly increase the allowance for credit losses and/or sustain credit losses that are significantly higher than the reserve provided. For more information, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates” contained in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this 2025 Form 10-K.

We are subject to an extensive body of accounting rules and best practices. Periodic changes to such rules may change the treatment and recognition of critical financial line items and affect our profitability.

Our business operations are significantly influenced by the extensive body of accounting regulations in the United States. Regulatory bodies periodically issue new guidance, altering accounting rules and reporting requirements, which can substantially affect the preparation and reporting of our financial statements. These changes might necessitate retrospective application, potentially leading to restatements of prior period financial statements.

One such significant change in 2023 was the implementation of the current expected credit loss ("CECL") model, which we adopted on January 1, 2023. Under the CECL model, financial assets carried at amortized cost, such as loans and held-to-maturity debt securities, are presented at the net amount expected to be collected. This forward-looking approach in estimating expected credit losses contrasts starkly with the prior, "incurred loss" model, which delays recognition until a loss is probable. CECL mandates considering historical experience, current conditions, and reasonable forecasts affecting collectability, leading to periodic adjustments of financial asset values. However, this forward-looking methodology, reliant on macroeconomic variables, introduces the potential for increased earnings volatility due to unexpected changes in these indicators between periods. An additional consequence of CECL is an accounting asymmetry between loan-related income, recognized periodically based on the effective interest method, and credit losses, recognized upfront at origination. This asymmetry might create the perception of reduced profitability during loan expansion periods due to the immediate recognition of expected credit losses. Conversely, periods with stable or declining loan levels might seem relatively more profitable as income accrues gradually for loans where losses had been previously recognized.

Our growth or future losses may require us to raise additional capital in the future, but that capital may not be available when it is needed, or the cost of that capital may be exceedingly high.

We are required by federal regulatory authorities to maintain adequate levels of capital to support our operations. We anticipate that our capital resources will satisfy our capital requirements for the foreseeable future. Nonetheless, we may at some point need to raise additional capital to support continued growth or be required by our regulators to increase our capital resources. Our ability to raise additional capital, if needed, will depend on conditions in the capital markets at that time, which are outside our control, and on our financial condition and performance. Accordingly, we may not be able to raise additional capital, if needed, on terms that are acceptable to us. If we cannot raise additional capital when needed, our operations could be materially impaired and our financial condition and liquidity could be materially and adversely affected. In addition, if we are unable to raise additional capital when required by our banking regulators, we may be subject to additional adverse regulatory action.

Risks Related to Cybersecurity, Third Parties and Technology

We are subject to certain risks related to our use of technology, including the potential for cyber-attacks and system failures.

Our security measures may not be sufficient to mitigate the risk of a cyber-attack. Communications and information systems are critical to our operations, as we rely on them to manage customer relationships, maintain our general ledger, and support other business functions. Our operations depend on the secure processing, storage, and transmission of confidential information through our computer systems and networks. While we take protective measures and adapt them as circumstances evolve, our systems may remain vulnerable to breaches, unauthorized access, denial-of-service attacks, misuse, malware, or other cyber threats. Any such event could compromise our or our customers' confidential information, disrupt operations, or harm customers and counterparties. If these risks materialize, we may incur significant expenses to investigate and remediate security vulnerabilities, enhance protective measures, or address the impact of an attack. Such incidents could expose us to litigation, regulatory scrutiny, financial losses not fully covered by insurance, and reputational damage, which could deter customers from using our services.

Security breaches in our internet banking activities could further expose us to liability and reputational harm. Cybersecurity risks are particularly heightened in internet banking. Advances in criminal sophistication, technology, or vulnerabilities in third-party systems could lead to breaches that compromise the security of data and transactions, potentially discouraging customers from using our online services. A breach could result in financial losses, reputational harm, regulatory penalties, compliance costs, and legal liabilities, adversely affecting our financial condition and ability to grow our online services.

Increases in criminal activity levels and sophistication, advances in computer capabilities, new discoveries, vulnerabilities in third party technologies (including browsers and operating systems) or other developments could result in a compromise or breach of the technology, processes and controls that we use to prevent fraudulent transactions and to protect data about us, our customers and underlying transactions. Any compromise of our security could deter customers from using our internet banking services that involve the transmission of confidential information. Although we have developed and continue to invest in systems and processes that are designed to detect and prevent security breaches and cyber-attacks and periodically test our security, these precautions may not protect our systems from compromises or breaches of our security measures, and could result in losses to us or our customers, our loss of business and/or customers, damage to our reputation, the incurrence of additional expenses, disruption to our business, our inability to grow our online services or other businesses, additional regulatory scrutiny or penalties, or our exposure to civil litigation and possible financial liability, any of which could have a material adverse effect on our business, financial condition and results of operations.

We also rely on third-party providers for data processing and operational support. If a third-party vendor experiences disruptions, cyber-attacks, or fails to meet service standards, it could impair our ability to process transactions, deliver services, or conduct business. Transitioning to alternative vendors could involve significant delays and costs.

Our business may also be adversely affected by the increasing prevalence of fraud and other financial crimes. As a bank, we are vulnerable to fraudulent activity, which may result in financial losses, increased costs, or damage to our reputation. Fraud may take many forms, including check fraud, electronic fraud, wire fraud, phishing, and social engineering. Nationally, incidents of fraud and financial crimes have been on the rise, and we have experienced losses due to such activities. While we have policies and procedures to prevent these losses, we cannot guarantee that they will not occur.

We are subject to certain risks in connection with our data management or aggregation.

We are reliant on our ability to manage data and our ability to aggregate data in an accurate and timely manner to ensure effective risk reporting and management. Our ability to manage and aggregate data may be limited by the effectiveness of our policies, programs, processes and practices that govern how data is acquired, validated, stored, protected and processed. Many of our data management and aggregation processes are manual and subject to human error or system failure. Failure to manage data effectively and to aggregate data in an accurate and timely manner may limit our ability to manage current and emerging risks, as well as to manage changing business needs.

Risks Related to Our Business and Industry Generally

We are dependent on key personnel and the loss of one or more of those key personnel may materially and adversely affect our prospects.

Competition for qualified employees in the banking industry is intense, with a limited pool of candidates experienced in community banking. Our success relies on attracting and retaining skilled management, loan origination, finance, administrative, marketing, and technical personnel, as well as on the continued contributions of key executives, including our Chief Executive Officer, J. Chris Verenes, and other critical employees. Losing any of these individuals could result in a challenging transition period and negatively impact our operations. The loss of these key personnel or directors nearing retirement without suitable replacements could adversely affect our business.

Ineffective liquidity management could impair our ability to fund operations and jeopardize our financial condition, growth and prospects.

Maintaining sufficient liquidity is essential for the operation of our business. We require sufficient liquidity to meet customer loan requests, customer deposit maturities/withdrawals, payments on our debt obligations as they come due, and other cash commitments under both normal operating conditions and other unpredictable circumstances causing industry or general financial market stress. Our access to funding sources in amounts adequate to finance our activities on terms that are acceptable to us could be impaired by factors that affect us specifically, or the financial services industry or economy generally. Factors that could detrimentally impact our access to liquidity sources include a downturn in the geographic markets in which our loans and operations are concentrated or difficult credit markets. Our access to deposits may also be affected by the liquidity needs of our depositors. In particular, a majority of our liabilities are checking accounts and other liquid deposits, which are payable on demand or upon several days’ notice, while by comparison, a substantial majority of our assets are loans, which cannot be called or sold in the same time frame. Although we have historically been able to replace maturing deposits and advances as necessary, we might not be able to replace such funds in the future, especially if a large number of our depositors seek to withdraw their accounts, regardless of the reason. A failure to maintain adequate liquidity could materially and adversely affect our business, results of operations, or financial condition.

Additionally, collateralized public funds are bank deposits of state and local municipalities. These deposits are required to be secured by certain investment grade securities to ensure repayment, which on the one hand tends to reduce our contingent liquidity risk by making these funds somewhat less credit sensitive, but on the other hand reduces standby liquidity by restricting the potential liquidity of the pledged collateral. Although these funds historically have been a relatively stable source of funds for us, availability depends on the individual municipality’s fiscal policies and cash flow needs. At December 31, 2025, $129.8 million of our deposits were public funds.

The Company’s ability to pay dividends and make subordinated debt payments is subject to the ability of the Bank to make capital distributions to the Company.

Security Federal is a separate legal entity from the Bank and does not have significant operations of its own. The long-term ability of the Company to pay dividends to its stockholders and debt payments is based primarily upon the ability of the Bank to make capital distributions to Security Federal, and also on the availability of cash at the holding company level. The availability of dividends from the Bank is limited by the Bank’s earnings and capital, as well as various statutes and regulations. In the event, the Bank is unable to pay dividends to Security Federal, Security Federal may not be able to pay dividends on its common stock or make payments on its outstanding debt. Consequently, the inability to receive dividends from the Bank could adversely affect our financial condition, results of operations, and future prospects. At December 31, 2025, the Company had $75.3 million in unrestricted cash to support dividend and debt payments.

Item 1B. Unresolved Staff Comments

None.

Item 1C. Cybersecurity

We rely extensively on various information systems and other electronic resources to operate our business. In addition, nearly all of our customers, service providers and other business partners on whom we depend, including the providers of our online banking, mobile banking and accounting systems, use their own electronic information systems. Any of these systems can be compromised, including by employees, customers and other individuals who are authorized to use them, and bad actors using sophisticated and a constantly evolving set of software, tools and strategies to do so. The nature of our business, as a financial-services provider, and our relative size, make us and our business partners high-value targets for these bad actors to pursue. See “Risks Related to Information Security and Business Interruption” section of the Risk Factors included in Item 1A of this 2025 Form 10-K for additional information.

Accordingly, we have devoted significant resources to assessing, identifying and managing risks associated with cybersecurity threats, including:

●

Implementing an Information Security Program that establishes policies and procedures for security operations and governance;

●

Establishing an Information Technology Steering Committee that is responsible for security administration, including conducting regular assessments of our information systems, existing controls, vulnerabilities and potential improvements;

●

Implementing layers of controls and not allowing excessive reliance on any single control;

●

Employing a variety of preventative and detective tools designed to monitor, block and provide alerts regarding suspicious activity;

●

Continuously evaluating tools that can detect and help respond to cybersecurity threats in real-time;

●

Leveraging people, processes and technology to manage and maintain cybersecurity controls;

●

Maintaining a third party risk management program designed to identify, assess and manage risks associated with external service providers;

●

Performing due diligence with respect to our third-party service providers, including their cybersecurity practices;

●

Engaging third-party cybersecurity consultants, who conduct periodic penetration testing, vulnerability assessments and other procedures to identify potential weaknesses in our systems and processes; and

●

Conducting periodic cybersecurity training for our employees and the Company’s Board.

The Information Security Program is a key part of our overall risk management system, which is administered by our Information Technology Steering Committee. The program includes administrative, technical and physical safeguards to help protect the security and confidentiality of customer records and information.

From time-to-time, we have identified cybersecurity threats that require us to make changes to our processes and to implement additional safeguards. While we have not experienced cybersecurity incidents that have materially affected our business, operations, or financial condition to date, we recognize that evolving cyber threats present a continuing risk. A successful cybersecurity breach, particularly one affecting our critical systems or third-party service providers, could result in operational disruptions, financial losses, reputational damage, legal or regulatory consequences, and loss of customer confidence. For example, unauthorized access to our systems could lead to data theft, fraud, or extended downtime impacting our ability to provide financial services. If such an event were to occur, it could have a material adverse effect on our results of operations and financial condition.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

This discussion and analysis reviews our consolidated financial statements and other relevant statistical data and is intended to enhance your understanding of our financial condition and results of operations. The information in this section has been derived from the Consolidated Financial Statements and footnotes thereto, that appear in Part II, "Item 8. Financial Statements and Supplementary Data" and should be read in conjunction with these Consolidated Financial Statements and footnotes and the business and financial information provided in this 2025 Form 10-K.

General

As a South Carolina corporation, the Company is authorized to engage in any activity permitted by South Carolina General Corporation Law. Functioning as a single bank holding company, the Company leverages this structure to potentially broaden the scale and range of financial services beyond the current offerings of the Bank. This holding company setup not only grants the Company enhanced flexibility compared to the Bank but also allows for diversification of business activities through existing or newly formed subsidiaries, acquisitions, mergers with financial institutions, and other companies. Presently, there are no existing arrangements or agreements regarding such acquisitions, and the Company's future activities will be funded through the ongoing operations of the Bank and borrowings from third parties. Additionally, potential funding sources may include the sale of additional securities or income generated by the Company's various activities, although no plans for such actions are in place at this time.

The investment and other activities of the Company have had no significant impact on the results of operations for the periods presented in the Consolidated Financial Statements included herein. Given that all material business operations are conducted through the Bank, the following discussion of financial results is primarily indicative of the activities of the Bank.

The principal business of the Bank is accepting deposits from the general public and originating consumer, commercial, and mortgage loans, including loans that enable borrowers to purchase or refinance one-to-four family residential properties. The Bank also originates construction loans for single-family residences, multi-family dwellings, commercial real estate, and residential subdivisions, as well as loans for commercial development projects. The Bank also provides trust services and it offers property and casualty insurance products through its subsidiary, SFINS.

The Bank's net income depends primarily on its interest rate spread, which is the difference between the average yield earned on its loan and investment portfolios and the average rate paid on its deposits and borrowings. When the rate earned on interest-earning assets equals or exceeds the rate paid on interest-bearing liabilities, this positive interest rate spread will generate net interest income. The Bank’s interest spread is influenced by interest rates, deposit flows, and loan demands. Levels of non-interest income and operating expense are also significant factors in earnings.

Critical Accounting Estimates

We prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”). In doing so, we have to make estimates and assumptions. Our critical accounting estimates are those estimates that involve a significant level of uncertainty at the time the estimate was made, and changes in the estimate that are reasonably likely to occur from period to period, or use of different estimates that we reasonably could have used in the current period, would have a material impact on our financial condition or results of operations. Accordingly, actual results could differ materially from our estimates. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. We have reviewed our critical accounting estimates with the audit committee of our Board of Directors.

The significant accounting policies of the Company are described in Note 1 of the Notes to the Consolidated Financial Statements included under "Item 8. Financial Statements and Supplementary Data," in this 2025 Form 10-K.

The Company believes the allowance for credit losses is a critical accounting policy that requires the most significant judgments, estimates and assumptions used in preparation of the Consolidated Financial Statements. The impact of an unexpectedly large loss could deplete the allowance and potentially require increased provisions to replenish the allowance, which would negatively affect earnings. The Company considers the allowance for credit losses to be a critical accounting policy, requiring significant judgments, estimates, and assumptions in preparing its Consolidated Financial Statements. An unexpectedly large loss could deplete the allowance, necessitating increased provisions that may negatively impact earnings. The CECL method is employed for credit loss provisioning, with all credit losses and recoveries charged and credited, respectively, to the related allowance. Additions to the allowance are determined based on various factors, including collateral value, borrower guarantees, repayment ability, loan portfolio composition, and economic conditions. Monthly evaluations are conducted, adjusting the allowance in response to changes. While management uses the best available information, future adjustments may be necessary if economic conditions differ significantly from assumptions. Further details on the estimation process and methodology are discussed in the “Financial Condition” and “Comparison of the Years Ended December 31, 2025 and 2024 - Provision for Credit Losses” sections of this 2025 Form 10-K.

The Company uses assumptions and estimates in determining income taxes payable or refundable for the current year, deferred income tax liabilities and assets for events recognized differently in its financial statements and income tax returns, and income tax expense. Determining these amounts requires analysis of certain transactions and interpretation of tax laws and regulations.

The Company exercises considerable judgment in evaluating the amount and timing of recognition of the resulting tax liabilities and assets. These judgments and estimates are reevaluated on a continual basis as regulatory and business factors change.

No assurance can be given that either the tax returns submitted by the Company or the income tax reported on the Consolidated Financial Statements will not be adjusted by either adverse rulings by the United States Tax Court, changes in the tax code, or assessments made by the Internal Revenue Service.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Financial Condition - Assets

Total assets increased $6.3 million or 0.4% to $1.62 billion at December 31, 2025 from $1.61 billion at December 31, 2024. This increase was primarily due to increases in investment securities and bank owned life insurance ("BOLI"), partially offset by decreases in cash and cash equivalents, net loans receivable and other assets.

Cash and cash equivalents decreased $102.9 million or 57.7% to $75.3 million at December 31, 2025 compared to $178.3 million at December 31, 2024, due to increased investment securities and the payoff of FRB borrowings and junior subordinated debentures during the year ended December 31, 2025.

Total investment securities increased $115.5 million or 17.5% to $776.3 million at December 31, 2025 from $660.8 million at December 31, 2024 as purchases of investments exceeded maturities, sales and principal paydowns during the year. The Company purchased $228.3 million of investment securities during the year ended December 31, 2025 compared to $71.9 million during 2024.

Loans receivable, net, including loans held for sale, decreased $10.9 million or 1.6% to $676.2 million at December 31, 2025 from $687.1 million at December 31, 2024. The decrease was due to a decline in construction loan balances, which was partially offset by growth in all remaining loan categories in 2025.

Construction loans decreased $43.4 million or 39.4% to $66.6 million at December 31, 2025 from $109.9 million at December 31, 2024. The decrease in construction loans was partially offset by growth in all other loan categories. The most significant growth occurred in our residential and commercial real estate loan portfolios. Residential mortgage loans held for investment increased $16.3 million or 8.0% to $219.9 million at December 31, 2025 from $203.7 million at December 31, 2024. Commercial real estate loans increased $6.8 million or 2.4% to $295.3 million at December 31, 2025, from $288.5 million at December 31, 2024. Additionally, commercial and agricultural loans increased by $1.0 million, HELOCs by $5.2 million, and other consumer loans by $21,000.

Loans held for sale, comprised of fixed rate residential loans, totaled $3.1 million at December 31, 2025 compared to $599,000 at December 31, 2024 . Typically, long-term fixed-rate residential real estate loans, when newly originated, are not retained in the portfolio but are promptly sold, unlike ARM loans, which are generally held in the portfolio. The Bank sells its fixed-rate residential loans on a service-released basis. The total value of fixed-rate residential loans sold to institutional investors on a service-released basis was $39.8 million during the year ended December 31, 2025 , compared to $30.2 million during the year ended December 31, 2024 .

Other assets decreased $3.9 million or 23.2% to $12.9 million at December 31, 2025 from $16.8 million at December 31, 2024. The decrease was primarily the result of a $3.5 million decrease in the net deferred asset associated with the change in market value of our AFS investment securities.

Financial Condition - Non-Performing Assets

The Bank’s non-performing assets, consisting of nonaccrual loans and OREO, decreased $1.8 million or 23.5% to $5.8 million at December 31, 2025, from $7.6 million at December 31, 2024. At December 31, 2025 and 2024, the Bank did not have any loans that were 90 days or more past due and still accruing interest. Non-performing assets represented 0.36% and 0.47% of total assets at December 31, 2025 and 2024, respectively. The ratio of the allowance for credit losses to total loans was 1.97% and 1.98% at December 31, 2025 and 2024, respectively.

The following table presents information regarding the Bank’s non-performing loans at the dates indicated.

		As of December 31, 2025					At December 31, 2024
(Dollars in thousands)	Amount			# of loans		Amount			# of loans		$ Change			% Change
Non-Accrual Loans:

The decrease in non-performing assets at December 31, 2025, was primarily driven by lower levels of non-performing loans in all categories except other consumer loans when compared to the year ended December 31, 2024. The largest decrease occurred in non-performing construction loans, which decreased $977,000 or 67.9% to $461,000 at December 31, 2025, from $1.4 million at December 31, 2024. At December 31, 2025, non-performing construction loans consisted of three loans to three borrowers, with an average loan balance of $154,000, compared to four loans to four borrowers with an average loan balance of $252,000 at December 31, 2024.

Non-performing residential real estate loans decreased $131,000 or 7.7% to $1.6 million at December 31, 2025, up from $1.7 million at December 31, 2024. Non-performing residential real estate loans at December 31, 2025, consisted of 19 loans to 19 borrowers with an average loan balance of $83,000, compared to 19 loans to 19 borrowers with an average loan balance of $113,000, at December 31, 2024.

Non-performing commercial real estate loans declined $399,000 or 10.9% to $3.3 million at December 31, 2025, from $3.7 million at December 31, 2024. At December 31, 2025, non-performing commercial real estate loans consisted of six loans to six borrowers, with an average loan balance of $543,000, compared to seven loans to seven borrowers, with an average loan balance of $523,000 at December 31, 2024.

Non-performing commercial and agricultural loans decreased $138,000 or 41.7% to $193,000 at December 31, 2025, compared to $331,000 at December 31, 2024. At December 31, 2025, non-performing commercial and agricultural loans consisted of seven loans to seven borrowers, with an average loan balance of $24,000, compared to five loans to five borrowers, with an average loan balance of $66,000 at December 31, 2024.

Non-performing HELOCs decreased $262,000 or 61.8% to $162,000 at December 31, 2025, compared to $424,000 at December 31, 2024. At December 31, 2025, non-performing HELOCs consisted of four loans to four borrowers, with an average loan balance of $40,000, compared to seven loans to seven borrowers, with an average loan balance of $61,000 at December 31, 2024.

Offsetting these decreases was a $68,000 or 87.2% increase in non-performing other consumer loans and a $45,000 increase in OREO at December 31, 2025.

Our strategy is to work with our borrowers to reach acceptable payment plans while protecting our interests in the underlying collateral. In the event an acceptable arrangement cannot be reached, we may have to acquire these properties through foreclosure or other means and subsequently sell, develop, or liquidate them.

The Bank conducts a monthly review of its loan portfolio and allowance for credit losses. In determining the appropriate allowance during the years ended December 31, 2025 and 2024, management considered various factors, including national and state unemployment rates, benefit claim levels, government financial assistance, inflation, consumer spending trends, and the Bank's largest commercial loan relationships.

Management will continue monitoring economic conditions and collaborating with borrowers to navigate this challenging economic climate. Future additions to the allowance for credit losses depend on factors such as loan portfolio performance, economic conditions, real estate values, and interest rates. There is no assurance that future periods won't require additions to the allowance. Determining the appropriate level of the allowance involves a high degree of subjectivity and significant estimates, all of which are subject to material changes.

Deterioration in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans and other factors, both within and outside of our control, may require an increase in the allowance for credit losses. The ultimate impact will depend on future developments, which are highly uncertain and cannot be predicted. In addition, bank regulatory agencies periodically review our allowance for credit losses and may require an increase in the provision for credit losses or the recognition of further loan charge-offs, based on judgments different than those of management. If charge-offs in future periods exceed the allowance for credit losses, we will need additional provisions to increase the allowance for credit losses. Any increases in the allowance for credit losses will result in a decrease in net income and, possibly, capital, and may have a material adverse effect on our financial condition and results of operations. Management continually monitors its loan portfolio for the impact of local economic changes.

Financial Condition - Liabilities and Shareholders' Equity

The majority of the Bank’s deposits are originated within the Bank’s immediate market area. Total deposits increased $47.7 million or 3.6% to $1.37 billion at December 31, 2025, up from $1.32 billion at December 31, 2024. The increase primarily was the result of a $46.6 million or 10.4% increase in money market account balances and, to a lesser extent, a $6.5 million or 1.3% increase in checking account balances. We believe the majority of the increases in deposits were due to competitive promotional rates for money market accounts.

We had brokered time deposits of $5.1 million and $25.8 million at December 31, 2025 and 2024, respectively. We use brokered time deposits as part of our interest rate risk management strategy, as they provide access to large deposit amounts at competitive rates that are typically slightly higher than those available in our market areas. A portion of these brokered time deposits includes a call option, allowing the Bank to redeem them early should interest rates shift. Additionally, the Bank maintained $6.3 million and $5.4 million in non-certificate brokered deposits at December 31, 2025 and 2024, respectively. Brokered deposits were 0.8% and 2.5% of total deposits at December 31, 2025 and 2024, respectively.

Total uninsured deposits (those that met or exceeded the FDIC insurance limit of $250,000) totaled $334.4 million and $365.8 million at December 31, 2025 and 2024, respectively. The uninsured amounts are estimates based on the methodologies and assumptions used for the Bank's regulatory reporting requirements. The Bank had no deposit relationships greater than 5.0% of outstanding deposits at either December 31, 2025 or 2024.

Certificates of deposits exceeding the FDIC insurance limit totaled $81.1 million and $96.0 million at December 31, 2025 and 2024, respectively. The following table summarizes the maturity schedule of certificates of deposit with a balance of $250,000 or more at December 31, 2025:

	(In Thousands)
Within 3 Months	$	22,176
After 3 Months, Within 6 Months		30,251
After 6 Months, Within 12 Months		23,401
After 12 Months		5,267
	$	81,095

Certificates of deposit scheduled to mature in one year or less totaled $253.1 million at December 31, 2025 compared to $198.3 million at December 31, 2024. Management’s policy is to maintain deposit rates at levels that are competitive with other local financial institutions. Based on historical experience, we believe that a significant portion of maturing certificates of deposit will remain with the Bank.

We had no outstanding FHLB advances at December 31, 2025 and 2024. We also had no outstanding borrowings from the FRB at December 31, 2025, compared to $50.0 million in outstanding borrowings under the FRB's BTFP with a weighted average borrowing rate of 4.76% at December 31, 2024. The Company originally elected to participate in the BTFP during 2023 to refinance existing FRB discount window borrowings at a lower fixed rate. Advances under that program had a one-year term and were priced at the one year overnight index swap (“OIS”) rate plus 10 basis points on the day the advance was made. Effective January 24, 2024, the FRB announced that future advances through the BTFP’s expiration on March 11, 2024, would be set at no lower than the interest rate on reserve balances in effect at the time of the advance. At December 31, 2025, we had pledged investment securities with an amortized cost of $312.9 million and a fair value of $293.9 million as collateral for FRB borrowings compared to an amortized cost and fair value of $370.2 million and a fair value of $341.0 million, respectively, at December 31, 2024, respectively.

Other borrowings decreased $2.5 million or 9.2% to $25.3 million at December 31, 2025 from $27.8 million at December 31, 2024. These borrowings consist of short-term repurchase agreements with certain commercial demand deposit customers for sweep accounts. The repurchase agreements typically mature within one to three days, and the interest rate paid on these borrowings floats monthly with money-market type rates. The interest rate paid on the repurchase agreements was 1.49% at both December 31, 2025 and 2024, respectively. We had pledged, as collateral for these repurchase agreements, investment securities with amortized costs and fair values of $36.4 million and $34.4 million at December 31, 2025, and $42.1 million and $39.7 million at December 31, 2024, respectively.

During 2025, the Company redeemed its junior subordinated debentures leaving no remaining balance at December 31, 2025 compared to $5.2 million in junior subordinated debentures outstanding at December 31, 2024. In addition, the Company had $10.0 million in subordinated debentures (“Notes”) outstanding compared at both December 31, 2025 and 2024. During the year ended December 31, 2024, the Company repurchased $16.5 million in principal of the Notes. For additional information, refer to Notes 12 and 13 of the Notes to Consolidated Financial Statements included under "Item 8. Financial Statements and Supplementary Data" in this 2025 Form 10-K.

Total shareholders' equity increased $18.1 million or 9.9% to $200.5 million at December 31, 2025 from $182.4 million at December 31, 2024. The increase was primarily attributable to net income available to common shareholders of $13.7 million during 2025 and a $10.5 million decrease in accumulated other comprehensive loss, net of tax, related to the unrecognized gain in value of AFS securities during the year ended December 31, 2025. These increases were partially offset by $2.2 million in dividends paid to common shareholders, $1.7 million in dividends paid to preferred shareholders and $2.3 million paid for share repurchases. Book value per common share was $37.74 at December 31, 2025 compared to $31.21 at December 31, 2024.

Results of Operations

The following table presents the dollar amount of changes in interest income and interest expense for major components of interest-earning assets and interest-bearing liabilities. The table also distinguishes between the changes related to higher or lower outstanding balances and the changes related to the volatility of interest rates. For each category of interest-earning assets and interest-bearing liabilities, information is provided on changes attributable to: (1) changes in rate (multiplied by prior year volume); (2) changes in volume (multiplied by prior year rate); and (3) net change (the sum of the prior columns). For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately to the change attributable to volume and the change attributable to rate. Changes in income are calculated on a tax equivalent basis using the effective tax rate for the period.

Average Balances, Interest Income and Expenses, and Average Yields and Rates

The following table compares detailed average balances, average yields on interest-earning assets, and average costs of interest-bearing liabilities at December 31, 2025 and 2024. The average balances were derived from the daily balances throughout the periods indicated. The average yields or costs were calculated by dividing the income or expense by the average balance of the corresponding assets or liabilities. Nonaccrual loans are included in earning assets in the following tables. Loan yields have been reduced to reflect the negative impact on our earnings of loans on nonaccrual status.

Comparison of the Years Ended December 31, 2025 and 2024

Net Income Available to Common Shareholders

Net income available to common shareholders increased $3.1 million or 35.3% to $12.0 million or $3.80 per basic common share for the year ended December 31, 2025, compared to $8.9 million or $2.77 per basic common share for the year ended December 31, 2024. The increase in net income was primarily due to increases in net interest income and non-interest income and a reduction to the provision for credit losses, which were partially offset by an increase in non-interest expense.

Net Interest Income

Net interest income increased $5.3 million or 12.8% to $47.2 million for the year ended December 31, 2025, compared to $41.8 million in 2024. The increase was due to higher interest income from loans and taxable investment securities combined with a decrease in interest expense on long term debt and non certificate deposit accounts. These were partially offset by lower interest income from deposits in other banks and an increase in interest expense on certificate of deposit accounts. The net interest margin on a tax-equivalent basis increased 28 basis points to 3.13% for the year ended December 31, 2025 from 2.85% for the year ended December 31, 2024.

Total average interest-earning assets increased $41.5 million or 2.8% to $1.51 billion for the year ended December 31, 2025 from $1.47 billion for the year ended December 31, 2024, despite a five basis point decrease in the average yield earned on these assets. Similarly, average interest-bearing liabilities increased $10.9 million or 1.0% to $1.14 billion for the year ended December 31, 2025 from $1.13 billion for the year ended December 31, 2024, while the average cost of these liabilities decreased 38 basis points to 2.76%. The interest rate spread on a tax-equivalent basis increased 33 basis points to 2.45% for the year ended December 31, 2025 from 2.12% in 2024.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Total interest income increased $1.3 million or 1.7% to $78.6 million for the year ended December 31, 2025, compared to $77.3 million for the year ended December 31, 2024, as a result of increased interest income on loans and taxable investments. Interest income on loans increased $2.8 million or 6.8% to $44.1 million for the year ended December 31, 2025 compared to $41.3 million for the year ended December 31, 2024. The increase was due to a $23.0 million increase in the average balance of loans outstanding combined with a 20 basis point increase in the average loan yield during the year ended December 31, 2025.

Interest income on taxable investment securities increased $511,000, or 1.7%, due to a $45.9 million increase in the aggregate average balance of these interest-earning assets, partially offset by a 22 basis point decrease in the average yield earned during 2025 compared to 2024. Conversely, tax equivalent interest income on non-taxable investment securities decreased $70,000 or 13.3%, due to a $4.3 million decrease in the aggregate average balance of these assets, which was partially offset by a decrease of 79 basis points in the average yield earned on these assets during 2025 compared to 2024.

Interest income on deposits with other banks decreased $2.0 million or 31.9% to $4.2 million for the year ended December 31, 2025, compared to $6.1 million for prior year. This decrease was due to a $23.2 million decrease in the average balance of deposits with other banks. The average yield earned on these deposits was 4.31% for the year ended December 31, 2025, compared to 5.11% in 2024.

Total interest expense decreased $4.0 million or 11.4% to $31.4 million for the year ended December 31, 2025, compared to $35.5 million for the year ended December 31, 2024, due to a 38 basis point decrease in the average cost of interest-bearing liabilities, which was partially offset by a $10.9 million increase in their average balance. Interest expense on deposits increased $304,000 or 1.0% to $30.2 million for the year ended December 31, 2025. The average balance of interest-bearing deposits increased $96.0 million or 9.6% to $1.1 billion during the year ended December 31, 2025, compared to $1.0 billion during 2024 while the average cost of these deposits decreased 23 basis points to 2.75% in 2025 from 2.98% in 2024.

Interest expense on all borrowed funds decreased $4.3 million or 77.1% to $1.3 million during 2025, compared to $5.6 million during the prior year. The decrease was attributable to both a $85.1 million or 67.1% decrease in the average balance of all borrowings and a 135 basis point decrease in the average cost of borrowings, which fell to 3.09% in 2025 from 4.44% during 2024. Most of the decrease in interest expense was for FRB and other borrowings, which decreased $3.5 million to $453,000 for 2025 due to both a $70.1 million decrease in the average balance and a 239 basis point decrease in the average cost of these liabilities in 2025.

Provision for Credit Losses

We recorded a $235,000 reversal of credit losses for the year ended December 31, 2025. This consisted of a $194,000 reversal of credit losses on loans and a $41,000 reversal of credit losses on unfunded commitments, compared to a $1.4 million provision for credit losses for the year ended December 31, 2024, which consisted of a $1.5 million provision for credit losses on loans and a $110,000 reversal of credit losses on unfunded commitments. The decrease in the provision was due to a reduction in loan balances and a decrease in substandard loans. Non-performing assets represented 0.36% and 0.47% of total assets at December 31, 2025 and 2024, respectively. Net charge-offs totaled $171,000 for the year ended December 31, 2025, compared to $155,000 in 2024. Non-performing assets, consisting of nonaccrual loans and OREO, decreased $1.8 million, or 23.5%, to $5.8 million at December 31, 2025 from $7.6 million at December 31, 2024.

The provision for credit losses is determined as part of management's ongoing monthly assessment of the loan portfolio's credit quality and the adequacy of the allowance for credit losses. The Company follows established policies and procedures to evaluate and monitor credit quality, including internal and external loan reviews to identify potential problem loans. The Asset Classification Committee conducts monthly reviews, and the Board of Directors evaluates the adequacy of the allowance for credit losses on a quarterly basis.

Management believes the allowance for credit losses at December 31, 2025 is adequate based on its best estimates of the expected losses in the loan portfolio; however, these estimates are subject to uncertainty. Since the allowance for credit losses is an estimation, there is no guarantee that actual credit losses will not exceed the allowance or that further increases in the allowance will not be necessary in the future. A significant deterioration in national and local economic conditions, triggered by factors like inflation, recession, unemployment or money supply fluctuations, could lead to a substantial increase in the allowance for credit losses, potentially adversely impacting the Company’s financial condition and results of operations. In addition, bank regulatory agencies may require us to make additional provisions to the allowance for credit losses during examinations, based on their own judgments and estimates.

Non-Interest Income

Non-interest income increased $1.3 million or 12.5% to $11.5 million for the year ended December 31, 2025 from $10.2 million for the year ended December 31, 2024, with increases occurring in all categories except gain on sale of investment securities, net and trust income. Increases in gain on sales of loans, grant income, and other non-interest income, which includes rental income, were the primary drivers of the increase in non-interest income.

Gain on sales of loans increased $115,000 or 14.8% to $894,000 for the year ended December 31, 2025, compared to the prior year, as the dollar volume of loans sold to investors increased. The Bank sold $39.8 million of loans in 2025 compared to $31.3 million during 2024.

We received $1.1 million and $500,000 in grant income during the years ended December 31, 2025 and 2024, respectively. All grant income received in 2025 was from a Community Development Financial Institution (“CDFI”) Financial Assistance ("FA") Award, while the grant income received in 2024 included a $220,000 CDFI FA Award and $280,000 through the CDFI Fund Bank Enterprise Award ("BEA") program. These grants were allocated to support the Bank's ongoing initiatives in community development financing and service activities within the most economically distressed communities.

Other non-interest income increased $658,000 or 87.2% to $1.4 million for the year ended December 31, 2025 compared to $407,000 in 2024 primarily due to increased rental income. During the first quarter of 2025, we purchased a multi-tenant property resulting in a $548,000 increase in rental income in 2025 when compared to the prior year. The property is intended to be the future site of a full-service branch for the Bank.

These increases were offset by a $371,000 decrease in trust income to $1.9 million for the year ended December 31, 2025 compared to $2.3 million in 2024 primarily due to non-recurring estate settlement fees received in 2024.

Non-Interest Expense

Non-interest expense increased $3.5 million or 9.1% to $41.6 million during the year ended December 31, 2025 compared to $38.1 million in 2024. This increase was primarily a result of increases in compensation and employee benefits, occupancy expense, debit card expenses and data processing expenses in 2025.

Compensation and employee benefits increased $2.2 million or 10.1% to $24.0 million during the year ended December 31, 2025 from $21.8 million in 2024. This increase was primarily due to an increase in employee salaries and annual cost-of-living adjustments.

Occupancy expenses increased $397,000 or 12.0% to $3.7 million in 2025 from $3.3 million in 2024, primarily due to increased utilities, taxes and building maintenance costs in 2025.

Debit card expenses increased $378,000 or 24.2% to $1.9 million during the year ended December 31, 2025 from $1.6 million in 2024, primarily due higher transaction volumes and rising transaction costs.

Data processing expenses increased $230,000 or 16.3% to $1.6 million during the year ended December 31, 2025 as a result of increases in the cost of services provided by third-party vendors and higher transaction volume when compared to the prior year.

Provision for Income Taxes

The provision for income taxes increased $901,000 or 32.7% to $3.7 million during the year ended December 31, 2025 compared to $2.8 million for the year ended December 31, 2024 due to an increase in pre-tax income. The Company's combined federal and state effective income tax rate was 21.1% for 2025 compared to 21.9% for 2024.

The Bank is subject to minimum capital requirements imposed by the FDIC. Based on capital levels at December 31, 2025, the Bank was considered to be well capitalized. At December 31, 2025, the Bank exceeded all regulatory capital requirements with Tier 1 leverage-based capital, Tier 1 risk-based capital, total risk-based capital, and common equity Tier 1 (CET1) capital ratios of 10.2%, 19.3%, 20.6%, and 19.3%, respectively. CET1 consists of Tier 1 capital less all capital components that are not considered common equity.

In addition to the FDIC’s minimum capital ratios, the Bank is required to maintain a capital conservation buffer consisting of additional CET1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses. At December 31, 2025, the Bank’s capital conservation buffer was 12.6%.

For additional information regarding the Bank's and Company's regulatory capital compliance, see the discussion included in Note 15 of the Notes to Consolidated Financial Statements included under "Item 8. Financial Statements and Supplementary Data" in this 2025 Form 10-K.

Liquidity and Capital Resources

Liquidity refers to the ability to generate sufficient cash flows to fund current loan demand, repay maturing borrowings, fund maturing deposit withdrawals, and meet operating expenses. Our primary sources of funds include deposits, scheduled loan and investment security repayments, including interest payments, maturities and sales of loans and investment securities, borrowings from the FRB, advances from the FHLB and cash flow generated from operations. The need for funds varies among periods depending on funding needs as well as the rate of amortization and prepayment on loans. The use of borrowings from the FRB, FHLB advances and other borrowings varies depending on loan demand, deposit inflows, and the use of investment leverage strategies that we might employee to increase net interest income.

Our principal use of funds is the origination of mortgages and other loans, and the purchase of investment securities. The Bank’s liquidity is impacted by the volume of loans sold and principal payments received. During the years ended December 31, 2025 and 2024, the Bank sold $39.8 million and $31.3 million in loans, respectively. During the same periods, the change in loans outstanding, accounting for originations and principal repayments (excluding loans held for sale), was a net decrease $13.6 million and a net increase of $66.5 million, respectively. Further, purchases of investment securities totaled $228.3 million during 2025 compared to $71.9 million during 2024. Other uses of funds in 2025 included repayment of FRB borrowings and junior subordinated debentures, property and equipment purchases and improvements, repurchases of common stock and $3.9 million in dividend payments to common and preferred shareholders.

In the normal course of business, we make off-balance sheet arrangements, including credit commitments to its customers to meet their financial needs. These arrangements involve, to varying degrees, elements of credit and interest rate risk not recognized in the consolidated statement of financial condition. We make personal, commercial, and real estate lines of credit available to customers and issue standby letters of credit.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Commitments to extend credit are subject to the Bank’s normal credit policies. At December 31, 2025, unused lines of credit on HELOCs, credit cards, and commercial loans totaled $136.4 million. The Bank also had undisbursed loans-in-process of $6.2 million, included in total unused commitments. These commitments are expected to be funded through loan amortizations, deposit inflows, principal payments on investments, and short-term borrowing capacity. See Note 18 of the Notes to the Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" in this 2025 Form 10-K for additional information regarding our commitments and off-balance sheet arrangements.

We incur capital expenditures on an ongoing basis to expand and improve our product offerings, enhance and modernize our technology infrastructure, and to introduce new technology-based products to compete effectively in our markets. We evaluate capital expenditure projects based on a variety of factors, including expected strategic impacts (such as forecasted impact on revenue growth, productivity, expenses, service levels and customer retention) and our expected return on investment. The amount of capital investment is influenced by, among other things, current and projected demand for our services and products, cash flow generated by operating activities, cash required for other purposes and regulatory considerations. Based on current capital allocation objectives, there are no projects scheduled for capital investments in premises and equipment during 2026 that would materially impact liquidity. We also have purchase obligations, generally with remaining terms of less than three years and contracts with various vendors to provide services, including information processing, for periods generally ranging from one to five years, for which our financial obligations are dependent upon acceptable performance by the vendor. For the year ending December 31, 2026, we project that fixed commitments will include $459,000 of operating lease payments. See Note 5 of the Notes to the Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" in this 2025 Form 10-K for additional information regarding our operating leases.

The Bank’s liquidity has been positively impacted by increases in deposit levels in recent years. During the year ended December 31, 2025, deposits increased by $47.7 million, bringing total deposits to $1.4 billion at year end. At December 31, 2025, the Bank had $75.3 million in cash and cash equivalents, compared to $178.3 million at December 31, 2024. In addition, the Bank held certificates of deposit at other banks and AFS investment securities, which together with cash and cash equivalents amounted to $740.1 million at December 31, 2025, up from $705.2 million at December 31, 2024. Total certificates of deposit scheduled to mature within one year totaled $279.1 million at December 31, 2025. Management’s policy is to maintain deposit rates at levels that are competitive with other local financial institutions. Based on historical experience, we believe that a significant portion of maturing certificates of deposit will remain with the Bank.

Primary sources of short-term liquidity for the Bank include borrowings from the FRB, the FHLB of Atlanta, and a $50.0 million line of credit with the Pacific Coast Bankers Bank. We had no outstanding FRB borrowings at December 31, 2025, compared to $50.0 million in outstanding borrowings under the FRB's BTFP with a weighted average borrowing rate of 4.76% at December 31, 2024. At December 31, 2025, we had pledged investment securities with an amortized cost of $312.9 million and a fair value of $293.9 million as collateral for these borrowings.

We had no outstanding FHLB advances at December 31, 2025 and 2024. The Bank maintains an approved line of credit with the FHLB of Atlanta, allowing for borrowing of up to 25% of the Bank’s assets, which, when utilized, is collateralized by a pledge against specific investment securities and/or eligible loans. As of December 31, 2025, the Bank has the ability to borrow $463.9 million based on the collateral value of pledged investment securities and loans. Management believes that future liquidity can be met through the Bank's deposits, which totaled $1.4 billion at December 31, 2025, as well as through sales and maturities of investment securities, and loans sold to investors. During the years ended December 31, 2025 and 2024, proceeds from sales, payments and maturities of investment securities totaled $123.7 million and $113.5 million, and loans sold to investors totaled $39.8 million and $31.3 million, respectively.

Historically the Bank’s cash flow from operating activities has been relatively stable. The cash flows from investing activities vary with sales of investment securities and with the need to invest excess funds or utilize leverage strategies with the purchase of investment securities. The cash flows from financing activities vary depending on the need for borrowings from the FRB, FHLB advances and other borrowings. The Bank's management regularly reviews its liquidity position and has implemented internal policies establishing guidelines for sources of asset-based liquidity and evaluates and monitors the total amount of purchased funds used to support the balance sheet and funding from noncore sources. The Bank's management believes that the liquid assets combined with the available lines of credit provide adequate liquidity to meet current financial obligations for at least the next 12 months.

Security Federal Corporation is a separate legal entity from the Bank and must provide for its own liquidity and pay its own operating expenses. Sources of capital and liquidity for Security Federal Corporation include distributions from the Bank and the issuance of debt or equity securities, although there are regulatory restrictions on the ability of the Bank to pay dividends. At December 31, 2025, Security Federal Corporation (on an unconsolidated basis) had liquid assets of $45.0 million. The Company currently expects to continue the current practice of paying quarterly cash dividends on common stock subject to the Board of Directors' discretion to modify or terminate this practice at any time and for any reason without prior notice. Our current quarterly common stock dividend rate in 2026 is $0.16 per share, as approved by our Board of Directors, which we believe is a dividend rate per share which enables us to balance our multiple objectives of managing and investing in the Bank, and returning a substantial portion of our cash to our shareholders. Assuming continued payment during 2026 at this rate of $0.16 per share, our average total common stock dividends paid each quarter would be approximately $498,000 based on the number of our current outstanding shares at December 31, 2025.

In June 2023, the Company announced that its Board of Directors approved a share repurchase program for the purchase of up to three percent, or approximately 97,612 shares, of the Company’s outstanding common stock as of that date. In general, stock-repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. On August 19, 2024, the Company's Board of Directors announced an additional 100,000 shares available to be purchased under the program. During the year ended December 31, 2025, the Company repurchased 74,066 shares of its common stock at an aggregate cost of $2.3 million, leaving 53,000 shares available for further repurchase under the existing stock repurchase program at December 31, 2025. The repurchase program does not obligate the Company to purchase any particular number of shares. For additional information, see Part II, Item 5 - “Unregistered Sales of Equity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities.”

Management's Discussion and Analysis of Financial Condition and Results of Operations

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of loss from adverse changes in market prices and rates. Our market risk arises principally from interest rate risk inherent in our lending, investing, deposit and borrowings activities. Management actively monitors and manages its interest rate risk exposure. In addition to other risks that we manage in the normal course of business, such as credit quality and liquidity, management considers interest rate risk to be a significant market risk that could potentially have a material effect on our financial condition and result of operations.

Asset and Liability Management

The objective of the Bank’s program of asset and liability management is to limit the Bank’s vulnerability to material and prolonged increases or decreases in interest rates, or "interest rate risk." As a financial institution, interest rate risk is the Bank's most significant market risk. The earnings and economic value of our shareholders’ equity varies in relation to changes in interest rates and the corresponding impact on the market values of our assets and liabilities. Oversight of the Bank's asset liability strategy is conducted by the Asset Liability Management Committee (“ALCO”).

The asset/liability management process is designed to achieve relatively stable net interest margins and assure liquidity by coordinating the volumes, maturities or re-pricing opportunities of interest-earning assets, deposits and borrowed funds. It is the responsibility of the ALCO to determine and achieve the most appropriate volume and mix of interest-earning assets and interest-bearing liabilities, as well as ensure an adequate level of liquidity and capital, within the context of corporate performance goals. The ALCO meets regularly to review interest rate risk and liquidity in relation to present and potential market conditions, and to evaluate funding and balance sheet management strategies to ensure the level of risk is consistent with our asset/liability objectives.

Simulation is the principal tool used by the Bank in its ongoing effort to measure interest rate risk. Simulation involves the use of a financial modeling system that provides reports showing the current and future impact of changes in interest rates and our strategies and tactics. The Bank uses two dynamic methods: net interest income (“NII”) simulation and economic value of equity (“EVE”) analysis.

The NII simulation models the impact that changes in interest rates will have on our earnings while EVE analysis models the impact those changes will have on the net present value of our asset and liability portfolios. These models take into account our contractual agreements with regard to investments, loans, deposits and borrowings, and also include assumptions surrounding market and customer behavior under different rate scenarios. The assumptions we use are based upon a combination of proprietary and market data that reflect historical results and current market conditions. These assumptions relate to interest rates, prepayments, deposit decay rates and the market value of certain assets and liabilities under the various interest rate scenarios. We use market data to determine prepayments and maturities of loans, investments and borrowings and use our own assumptions on deposit decay rates except for time deposits. Time deposits are modeled to reprice to market rates upon their stated maturities. We also assume that non-maturity deposits can be maintained with rate adjustments not directly proportionate to the change in market interest rates, based upon our historical deposit rates. We have demonstrated in the past that the tiering structure of our deposit accounts during changing rate environments results in relatively lower volatility and less than market rate changes in our interest expense for deposits. These assumptions are based upon our analysis of our customer base, competitive factors and historical experience.

While these models are dependent on the accuracy of the underlying assumptions, we believe that they provide a more meaningful illustration of the Bank's sensitivity to interest rate risk than a traditional static gap analysis. Significant deviations from these assumptions, such as faster-than-expected prepayments or deposit withdrawals, could materially affect actual results. These tools provide our ALCO with the capability to estimate and manage the amount of earnings at risk in future periods and in selected interest rate risk environments.

NII Simulation- The Bank’s primary focus is on NII simulation. which measures potential earnings exposure over the next 12 months under multiple instantaneous interest rate shock scenarios. Policy limits establish the maximum acceptable negative impact on net interest income for each rate change, and the ALCO monitors compliance with these limits, reporting to the Board of Directors quarterly.

The following table indicates the NII simulation scenario modeled and the applicable policy parameters.

Change in Market Rates		Maximum Allowable Change in NII Over			Hypothetical Change in NII Over
(in Basis Points)		12 Months			12 Months
400			(20.0	)%		1.8	%
300			(15.0	)%		2.4	%
200			(10.0	)%		2.3	%
100			(7.5	)%		1.4	%
—			—	%		—	%

(300	)		(15.0	)%		(10.3	)%
(400	)		(20.0	)%		(11.6	)%

The Bank performs a liquidity analysis, a component of managing liquidity risk and monitoring the Bank's asset liability strategy. This analysis compares outstanding sources of liquidity to applicable policy parameters. The Bank was in compliance with policy parameters as of December 31, 2025 and 2024. In addition, the Bank performs a contingency funding plan analysis which incorporates various simulations in order to evaluate Bank's funding resources under stressed conditions. Both the liquidity and contingency funding plan analysis are performed by the ALCO and presented to the Board of Directors quarterly.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Management's Discussion and Analysis of Financial Condition and Results of Operations

EVE simulation- The EVE analysis serves as an indicator of the extent to which the present value of our capital could change, given potential changes in interest rates. The difference represented by the present value of assets minus the present value of liabilities is defined as the economic value of equity. This measure assumes a static balance sheet and does not incorporate any growth assumptions, but does assume loan prepayments and certain other cash flows occur. It provides a measure of rate risk extending beyond the 12 month time horizon contained in the NII simulation analysis.

While an instantaneous and severe shift in interest rates is used in this analysis to provide an estimate of exposure under an extremely adverse scenario, a gradual shift in interest rates would have a much more modest impact. Since EVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in EVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon, i.e., the next fiscal year. Further, EVE does not take into account factors such as future balance sheet growth, changes in product mix, change in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates.

The following table indicates the EVE simulation scenarios modeled and the applicable policy parameters.

Change in Market Rates (In Basis Points)		Maximum Change in EVE			Hypothetical change in EVE
400			(40.0	)%		7.6	%
300			(30.0	)%		7.1	%
200			(20.0	)%		5.9	%
100			(10.0	)%		3.6	%
—			—	%		—	%
(100	)		(10.0	)%		(5.2	)%
(200	)		(20.0	)%		(12.6	)%
(300	)		(30.0	)%		(22.5	)%
(400	)		(40.0	)%		(33.6	)%

In evaluating the Bank's exposure to interest rate risk, certain shortcomings inherent in the method of analysis described above are considered. No assurance can be given that changing economic conditions and other relevant factors impacting our net interest income will not cause actual occurrences to differ from underlying assumptions. For example, loan repayment rates and withdrawals of deposits will likely differ substantially from the assumptions used in the simulation models in the event of significant changes in interest rates due to the option of borrowers to prepay their loans and the ability of depositors to withdraw funds prior to maturity. In addition, this analysis does not consider any strategic changes to our balance sheet which management may consider as a result of changes in market conditions.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Security Federal Corporation and Subsidiaries:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Security Federal Corporation and Subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in shareholders' equity and cash flows for the years then ended, and the related notes to the consolidated financial statements (collectively, the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with 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 financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Allowance for Credit Losses

The Company reported a gross loan portfolio of $686.6 million and related allowance for credit losses (“ACL”) of $13.5 million as of December 31, 2025. In order to measure expected credit losses on a collective basis, the Company has elected to utilize a weighted-average remaining life (“WARM”) methodology for all segments. Loans not sharing similar risk characteristics are evaluated on an individual basis. The WARM method applies a loss rate to a given pool of loans over the estimated remaining life of the given pool. The remaining life of the pool is based on Company historical data. In addition, a 6-month forecast is applied to each segment, based on external sources, with immediate reversion to historical loss rates at the end of the forecast period. Additionally, a qualitative scorecard is used by management to assess the need for adjustments to expected credit loss estimates for information not already captured in the quantitative loss estimation process. The qualitative scorecard evaluates certain risks such as portfolio risk, economic trends, lending policies, credit administration risk, and industry conditions.

We identified the Company’s estimate of the allowance for credit losses as a critical audit matter. The principal consideration for our determination of the ACL as a critical audit matter related to the high degree of complexity and judgment in the determination of significant model assumptions, specifically, the qualitative factor adjustments to quantitative loss rates. Auditing these complex judgments and assumptions made by the Company involves challenging auditor judgment due to the nature and extent of audit evidence and effort required to address these matters, including the extent of specialized skill or knowledge needed.

The primary procedures we performed to address this critical audit matter included the following:

• We obtained an understanding of the Company’s process for establishing the ACL, including the basis for development and related adjustments of the qualitative factor components of the ACL.

• We evaluated the relevance and reasonableness of key assumptions by assessing portfolio segmentation, credit quality indicators, current credit conditions, and the incorporation of reasonable and supportable economic forecasts.

• We tested the completeness and accuracy of significant inputs to the model including the underlying data used to develop the qualitative factors.

• We validated the mathematical accuracy of the calculation.

• We evaluated the reasonableness of assumptions and data used by the Company in developing the qualitative factors by comparing these data points to internally developed and third-party sources, and other audit evidence gathered.

We have served as the Company's auditor since 1998.

SECURITY FEDERAL CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

The following is a description of the more significant accounting and reporting policies used in the preparation and presentation of the accompanying consolidated financial statements. All significant intercompany transactions have been eliminated in consolidation.

Basis of Consolidation and Nature of Operations

The accompanying consolidated financial statements include the accounts of Security Federal Corporation (the “Company”) and its wholly owned subsidiary, Security Federal Bank (the “Bank”) and the Bank’s wholly owned subsidiaries, Security Federal Investments, Inc. ("SFINV") and Security Federal Insurance, Inc. (“SFINS”). SFINV was formed to hold investment securities and allow for better management of the securities portfolio. SFINS is an insurance agency offering auto, business, and home insurance. All significant intercompany transactions and balances have been eliminated in consolidation.

The Company also has a wholly owned subsidiary, Security Federal Statutory Trust (the “Trust”), which issued and sold fixed and floating rate capital securities of the Trust. However, under current accounting guidance, the Trust is not consolidated in the financial statements. The Bank is primarily engaged in the business of accepting savings and demand deposits and originating mortgage loans and other loans to individuals and small businesses for various personal and commercial purposes.

Cash and Cash Equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash and due from banks, interest-bearing balances in other banks, and federal funds sold. Cash equivalents have original maturities of three months or less.

Investment Securities

Investment securities are classified in one of three categories: HTM, AFS, or trading. Management determines the appropriate classification of debt securities at the time of purchase. Investment securities are classified as HTM when the Company has the positive intent and ability to hold the securities to maturity. These securities are recorded at cost and adjusted for amortization of premiums and accretion of discounts over a level yield basis. Callable debt securities held at a premium are amortized until the earliest call date. Prepayment assumptions on mortgage-backed securities are anticipated.

Management classifies investment securities that are not considered to be HTM as AFS. This type of investment is stated at fair value with unrealized gains and losses, net of tax, reported in a separate component of shareholders' equity (“accumulated other comprehensive income (loss)”). Gains and losses from sales of AFS investment securities are determined using the specific identification method. The Company had no investment securities classified as trading.

Allowance for Credit Losses – Available for Sale Securities

Management evaluates all AFS investment securities in an unrealized loss position on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. If the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security, the security is written down to fair value and the entire loss is recorded in earnings. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making the assessment, the Company may consider various factors including the extent to which fair value is less than amortized cost, performance of any underlying collateral, downgrades in the ratings of the security by a rating agency, the failure of the issuer to make scheduled interest or principal payments and adverse conditions specifically related to the security. If the assessment indicates that a credit loss exists, the present value of cash flows expected to be collected are compared to the amortized cost basis of the security and any excess is recorded as an allowance for credit losses, limited by the amount that the fair value is less than the amortized cost basis. Any unrealized loss that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Changes in the allowance for credit losses are recorded as provision for (reversal of) credit losses. Losses are charged against the allowance for credit losses when management believes an AFS security is confirmed to be uncollectible or when either of the criteria regarding intent or requirement to sell is met. At December 31, 2025, there was no allowance for credit losses related to the AFS portfolio. Accrued interest receivable on AFS securities totaled $2.3 million and $2.5 million at December 31, 2025 and 2024, respectively, and was excluded from the estimate of credit losses.

Allowance for Credit Losses – Held to Maturity Securities

Management measures expected credit losses on HTM debt securities on a collective basis by major security type. The estimate of expected credit losses is primarily based on the ratings assigned to the securities by debt rating agencies and the average of the annual historical loss rates associated with those ratings. The Company then multiplies those loss rates, as adjusted for any modifications to reflect current conditions and reasonable and supportable forecasts as considered necessary, by the remaining lives of each individual security to arrive at a lifetime expected loss amount. Additionally, private label collateralized mortgage obligation ("CMO") securities which are not explicitly or implicitly guaranteed by the U.S. government are evaluated utilizing underlying pool data such as historical loss rates, loan-to-value ratios and credit enhancement data. See "Note 3 - Investments, Held to Maturity" for additional information regarding the major HTM security types. There was no allowance for credit losses on HTM securities at December 31, 2025. Accrued interest receivable on HTM securities totaled $477,000 and $589,000 at December 31, 2025 and 2024, respectively, and was excluded from the estimate of credit losses.

Notes to Consolidated Financial Statements

Loans Receivable Held for Investment

Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts and deferred fees and costs. Accrued interest receivable related to loans is reported in accrued interest receivable on the consolidated balance sheets. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using methods that approximate a level yield without anticipating prepayments.

The accrual of interest is generally discontinued when a loan becomes 90 days past due and is not well collateralized and in the process of collection, or when management believes, after considering economic and business conditions and collection efforts, that the principal or interest will not be collectible in the normal course of business. Past due status is based on contractual terms of the loan. A loan is considered past due when a scheduled payment has not been received 30 days after the contractual due date.

All accrued interest is reversed against interest income when a loan is placed on nonaccrual status. Interest received on such loans is accounted for using the cost- recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, there is a sustained period of repayment performance, and future payments are reasonably assured.

Allowance for Credit Losses on Loans

The allowance for credit losses on loans is a valuation account that is deducted from the loans' 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 uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Accrued interest receivable on loans totaled $2.1 million and $2.3 million at December 31, 2025 and 2024, respectively, and was excluded from the estimate of credit losses. The allowance for credit losses on loans represents management’s estimate of lifetime credit losses inherent in loans as of the balance sheet date. The allowance for credit losses on loans is estimated by management using relevant available information, from both internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts.

The Company measures expected credit losses for loans on a pooled basis when similar risk characteristics exist. The Company has identified the following portfolio segments:

Real Estate

Construction - Construction loans consist of loans to construct a borrower’s primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date. These loans are typically secured by undeveloped or partially developed land in anticipation of completing construction of a 1-4 family residential property. There is risk these construction and development projects can experience delays and cost overruns exceeding the borrower’s financial ability to complete the project. Such cost overruns can result in foreclosure of partially completed and unmarketable collateral. In addition, construction loans consist of loans to finance land for development of commercial or residential real property and construction of multifamily apartments or other commercial properties. These loans are highly dependent on the supply and demand for commercial real estate as well as the demand for newly constructed residential homes and lots acquired for development. Deterioration in demand could result in decreased collateral values, which could make repayments of outstanding loans difficult for customers.

Residential Mortgage - Residential mortgages consist of loans to purchase or refinance the borrower’s primary dwelling, second residence or vacation home and are often secured by 1-4 family residential property. Significant and rapid declines in real estate values can result in borrowers having debt levels in excess of the current market value of the collateral.

Commercial Mortgage - Commercial mortgages can be broadly categorized into owner-occupied and non-owner-occupied loans. Owner-occupied commercial mortgages involve financing for the purchase or refinancing of nonresidential properties that are occupied by the borrowing operating companies. The collateral for these loans typically includes office buildings, warehouses, manufacturing facilities, and other commercial or industrial properties. These loans hinge on the borrowers' ability to achieve business results consistent with the projections made at the loan origination. Although the loans are secured by real property to mitigate risk, there is a possibility that the liquidation of collateral may not fully satisfy the obligation. Non-owner-occupied commercial mortgages are used for purchasing or refinancing investment nonresidential properties. The collateral for these loans encompasses office buildings and complexes, retail facilities, multifamily complexes, land under development, and various other commercial or industrial real estate. The primary risk associated with non-owner-occupied commercial mortgage loans is contingent upon the ability of the income-producing property that collateralizes the loan to generate sufficient cash flow for servicing the debt. Despite being collateralized by real property to mitigate risk, there remains the possibility that the liquidation of collateral will not entirely meet the obligation.

Commercial and Agricultural - Commercial and agricultural loans consist of loans or lines of credit to finance accounts receivable, inventory or other general business needs, business credit cards, and lease financing agreements for equipment, vehicles, or other assets. The primary risk associated with commercial and agricultural loans is the ability of borrowers to achieve business results consistent with those projected at origination. Failure to achieve these projections presents risk the borrower will be unable to service the debt consistent with the contractual terms of the loan or lease.

Consumer loans

Home equity - Home equity loans consist of home equity lines of credit and other lines of credit secured by first or second liens on the borrower’s primary residence. These loans are secured by both senior and junior liens on the residential real estate and are particularly susceptible to declining collateral values.

Other - Consumer loans consist of loans to finance unsecured home improvements, student loans, automobiles and revolving lines of credit that can be secured or unsecured. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral.

The Company calculates the allowance for credit losses on loans for each pool of loans using a remaining life loss methodology with a two quarter reasonable and supportable forecast period and an immediate reversion period. Management believes that the Company’s historical loss experience provides the best basis for its assessment of expected credit losses on loans to determine the allowance for credit losses on loans. The Company uses its own internal data to measure historical credit loss experience within the loan pools with similar risk characteristics over an economic cycle. The Company then forecasts the calculated historical loss rates over the calculated remaining life of loans by pool.

Notes to Consolidated Financial Statements

Additionally, the allowance for credit losses on loans calculation includes subjective adjustments for qualitative risk factors that are likely to cause estimated credit losses to differ from historical experience. These qualitative adjustments may increase or reduce reserve levels and include adjustments for lending management experience and risk tolerance, loan review and audit results, asset quality and portfolio trends, loan portfolio growth, industry concentrations, trends in underlying collateral, external factors and economic conditions not already captured.

Loans that do not share risk characteristics are evaluated on an individual basis. When management determines that foreclosure is probable and the borrower is experiencing financial difficulty, the expected credit losses on loans are based on the fair value of collateral at the reporting date adjusted for selling costs as appropriate.

Management evaluates the carrying value of the loans periodically and the allowance is adjusted accordingly. While management uses the best information available to make evaluations, future adjustments may be necessary if economic conditions differ substantially from the assumptions used in making these evaluations. The allowance for credit losses is subject to periodic evaluations by bank regulatory agencies that may require adjustments to be made to the allowance based upon the information that is available at the time of their examination.

Allowance for Credit Losses – Unfunded Commitments

Financial instruments include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit issued to meet customer financing needs. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses - unfunded commitments unless the commitments to extend credit are unconditionally cancellable, through a charge to provision for unfunded commitments, which is included in the provision for credit losses in the Company’s consolidated income statements. The allowance for credit losses – unfunded commitments is estimated by loan segment at each balance sheet date using the same methodologies as portfolio loans, taking into consideration the likelihood that funding will occur as well as any third-party guarantees. The allowance for credit losses - unfunded commitments is included in other liabilities on the Company’s consolidated balance sheets.

Loans Receivable Held for Sale

The Company originates fixed rate residential loans on a servicing released basis in the secondary market. Loans closed but not yet settled with institutional investors are carried in the Company’s loans held for sale portfolio. These loans are fixed rate residential loans that have been originated in the Company’s name and have closed. Virtually all these loans have commitments to be purchased by investors and the majority of these loans were locked in by price with the investors on the same day or shortly thereafter that the loan was locked in with the Company’s customers. Therefore, these loans present little market risk for the Company. The Company usually delivers to, and receives funding from, the investor within 30 days. Commitments to sell these loans to the investor are considered derivative contracts and are sold to investors on a “best efforts" basis. The Company is not obligated to deliver a loan or pay a penalty if a loan is not delivered to the investor. As a result of the short-term nature of these derivative contracts, the fair value of the mortgage loans held for sale in most cases is the same as the value of the loan amount at its origination. The carrying amount of these loans approximates fair value. Gains on the sale of loans are recorded within non‑interest income in the consolidated income statements. The gain recognized represents the difference between cash proceeds received over the carrying amount of loans sold.

Other Real Estate Owned

Other real estate owned represents real estate and other assets acquired through foreclosure or repossession and are initially recorded at the estimated fair value less costs to sell. Subsequent improvements are capitalized. Costs of holding real estate, such as property taxes, insurance, general maintenance and interest expense, are expensed as a period cost. Fair values are reviewed regularly and allowances for possible losses are established when the carrying value of the asset owned exceeds the fair value less estimated costs to sell. Fair values are generally determined by reference to an outside appraisal.

Premises and Equipment

Premises and equipment are carried at cost, net of accumulated depreciation. Depreciation of premises and equipment is amortized on a straight-line method over the estimated useful life of the related asset. Estimated lives are 7 to 40 years for buildings and improvements and generally 3 to 10 years for furniture, fixtures and equipment. Maintenance and repairs are charged to current expense. The cost of major renewals and improvements are capitalized.

Land Held for Sale

Land held for sale is reported at the lower of the carrying amount and fair value less costs to sell. No write-downs on land held for sale were recorded during 2025 or 2024.

Goodwill

The Company's goodwill is a result of the excess of the cost over the fair value of net assets resulting from the acquisition of Collier Jennings Financial Corporation in July 2006. Goodwill is reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable.

Notes to Consolidated Financial Statements

Income Taxes

Income tax expense or benefit is recognized for the net change in the deferred tax liability or asset during the year. That amount together with income taxes currently payable is the total amount of income tax expense or benefit for the year. Deferred taxes are provided for by the differences in financial reporting bases for assets and liabilities compared with their tax bases. Generally, a current tax liability or asset is established for taxes presently payable or refundable and a deferred tax liability or asset is established for future tax items. A valuation allowance, if applicable, is established for deferred tax assets that may not be realized. Deferred income taxes are provided for differences between the provision for credit losses for financial statement purposes and those allowed for income tax purposes.

The Company adopted accounting guidance which prescribes a threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on derecognition, classification, interest and penalties, accounting in interim periods and disclosures. There have been no gross amounts of unrecognized tax benefits or interest or penalties related to uncertain tax positions since adoption. There are no unrecognized tax benefits that would, if recognized, affect the effective tax rate. There are no positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease within the next 12 months.

Advertising Expense

Advertising and public relations costs are generally expensed as incurred. External costs relating to direct mailing are expensed in the period in which the direct mailings are sent. Advertising and public relations costs of $914,000 and $1.0 million were included in the Company’s results of operations for the years ended December 31, 2025 and 2024, respectively.

Stock-Based Compensation

The Company accounts for compensation costs under its stock option plans using the fair value method. This method 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 recognized in the income statement over the vesting period of the award.

Net Income Per Common Share

Accounting guidance specifies the computation, presentation and disclosure requirements for earnings per share (“EPS”) for entities with publicly held common stock or potential common stock such as options, warrants, convertible securities or contingent stock agreements if those securities trade in a public market. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding. Diluted EPS is similar to the computation of basic EPS except that the denominator is increased to include the number of additional common shares that would have been outstanding if the dilutive common shares had been issued. The dilutive effect of options outstanding under the Company’s stock option plan is reflected in diluted EPS by application of the treasury stock method.

There were no stock options outstanding as of December 31, 2025 and 2024; and therefore, no dilutive options in the calculation of diluted EPS for those periods. The following tables show the Company’s net income per common share for the years indicated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of income and expenses during the reporting periods. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include:

•

Determination of the allowance for credit losses and provision for credit losses

Segment Reporting

The Company adopted Accounting Standards Update 2023-07 “Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures” on January 1, 2024. The Company has determined that all of its banking divisions and subsidiaries meet the aggregation criteria of ASC 280, Segment Reporting, as its current operating model is structured in a manner where banking divisions and subsidiaries serve a similar base of primarily commercial clients utilizing a company-wide offering of similar products and services managed through similar processes and platforms that are collectively reviewed by the Company’s Executive Committee, which has been identified as the chief operating decision maker (“CODM”).

The CODM regularly assesses performance of the aggregated single operating and reporting segment and decides how to allocate resources based on net income calculated on the same basis as is net income reported in the Company’s consolidated statements of income and other comprehensive income. The CODM is also regularly provided with expense information at a level consistent with that disclosed in the Company’s consolidated statements of income and other comprehensive income. The measure of segment assets is reported on the balance sheet as total consolidated assets.

Recently Issued or Adopted Accounting Standards

The following is a summary of recent authoritative pronouncements that could affect accounting, reporting, and disclosure of financial information by the Company:

On January 1, 2024, the Company adopted ASU 2023-07, “Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures”. The Company has determined that all of it's banking divisions and subsidiaries meet the aggregation criteria of ASC 280, Segment Reporting. As such, the adoption did not have a material effect on it's financial statements.

In December 2023, the FASB amended the Income Taxes topic in the ASC to improve the transparency of income tax disclosures. The amendments were effective for annual periods beginning after December 15, 2024 and did not have a material effect on the Company's financial statements.

Other accounting standards that have been issued or proposed by the FASB or other standards-setting authorities are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.

Risks and Uncertainties

In the normal course of its business, the Company encounters two significant types of risk: economic and regulatory. There are three main components of economic risk: interest rate risk, credit risk, and market risk. The Company is subject to interest rate risk to the degree that its interest-bearing liabilities mature or reprice at different speeds, or on different bases, than its interest-earning assets. Credit risk is the risk of default on the Company’s loan portfolio that results from borrowers’ inability or unwillingness to make contractual payments. Market risk reflects changes in the value of collateral underlying loans receivable, the valuation of real estate held by the Company, and the valuation of loans held for sale and securities available for sale. The Company is subject to the regulations of various government agencies. These regulations can and do change significantly from period to period. The Company also undergoes periodic examinations by the bank regulatory agencies, which may subject it to further changes with respect to asset valuations, amounts of required loss allowances, and operating restrictions, resulting from the regulators’ judgments based on information available to them at the time of their examination.

Notes to Consolidated Financial Statements

Student Loan Pools are typically 97% guaranteed by the United States government while SBA bonds are 100% backed by the full faith and credit of the United States government. The other asset backed securities are interest-only strips on pools of guaranteed SBA 7(a) notes. The majority of the Bank's MBS are issued or guaranteed by an agency of the United States government such as Ginnie Mae, or by Government Sponsored Entities ("GSEs"), including Fannie Mae and Freddie Mac. Ginnie Mae MBS are backed by the full faith and credit of the United States government, while those issued by GSEs are not. Also included in MBS are private label collateralized mortgage obligation ("CMO") securities, which are issued by non-governmental real estate mortgage investment conduits and are not backed by the full faith and credit of the United States government. At December 31, 2025, the Bank held an amortized cost and fair value of $93.2 million and $91.1 million in private label CMO securities, compared to an amortized cost and fair value of $80.3 million and $76.0 million at December 31, 2024, respectively.

The amortized cost and fair value of AFS securities at December 31, 2025 are shown below by contractual maturity. Expected maturities will differ from contractual maturities because borrowers have the right to prepay obligations with or without call or prepayment penalties. Since MBS are not due at a single maturity date, they are disclosed separately, rather than allocated over the maturity groupings below.

The amortized cost and fair value of AFS securities pledged as collateral for certain deposit accounts, FHLB advances, FRB, and other borrowings were $439.5 million and $413.2 million at December 31, 2025, and $483.9 million and $446.1 million at December 31, 2024, respectively.

During the year ended December 31, 2025, we received $24.3 million in gross proceeds from sales of AFS securities and recognized gross gains of $57,000 and gross losses of $35,000. During the year ended December 31, 2024, we received $13.7 million in gross proceeds from sales of AFS securities and recognized gross gains of $408,000 and gross losses of $371,000.

At December 31, 2025, AFS securities consisted of 532 securities, 356 of which were in an unrealized loss position. The majority of unrealized losses are related to the Company’s SBA bonds, MBS, and taxable municipal bonds. The Company reviews its investment securities portfolio at least quarterly and more frequently when economic conditions warrant, assessing whether an allowance for credit loss is deemed necessary. Management’s evaluation of those securities with unrealized losses as of December 31, 2025 is discussed below.

Student Loan Pools

At December 31, 2025, there were 54 AFS student loan pool securities, 36 of which had unrealized losses. All securities with unrealized losses were rated AA or higher by Moody’s, Bloomberg, and/or S&P and each of the individual securities have credit enhancements further reducing potential realized losses. The unrealized losses on these securities are believed to be caused by the current interest rate environment, and not credit quality. Because the Company does not intend to sell these investments and it is not more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company did not recognize unrealized losses into income as of December 31, 2025.

SBA Bonds

SBA securities are fully backed by the U.S. government. At December 31, 2025, there were 107 SBA Bonds, 47 of which had unrealized losses. These unrealized losses related principally to changes in market interest rates. The contractual terms of the investments do not permit the issuer to settle the securities at a price less than the amortized cost bases of the investments. Because the Company does not intend to sell the investments and it is more likely than not that the Company will not be required to sell the investments before recovery of their amortized cost bases, which may be maturity, the Company did not recognize unrealized losses into income as of December 31, 2025.

Municipal Bonds

At December 31, 2025 there were 5 tax exempt municipal securities and 59 taxable municipal securities that had unrealized losses. Each of the Municipal securities held were rated “A2” (Moody’s) or “AA-” (S&P) or better. The Company believes the unrealized losses on those investments were caused by the interest rate environment and do not relate to the underlying credit quality of the issuers.
