2 CAUTIONARY STATEMENTS This presentation contains "forward-looking statements“ within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In addition, certain statements may be contained in Colony Bankcorp, Inc's (the "Company") future filings with the Securities and Exchange Commission (the "SEC"), in press releases, and in oral and written statements made by or with the approval of the Company that are not statements of historical fact and constitute “forward-looking statements” within the meaning of, and subject to the protections of, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Examples of forward-looking statements include, but are not limited to: (i) projections and/or expectations of revenues, income or loss, earnings or loss per share, the payment or nonpayment of dividends, capital structure and other financial items; (ii) statement of plans and objectives of Colony Bankcorp, Inc. or its management or Board of Directors, including those relating to products or services; (iii) statements of future economic performance; (iv) statements regarding growth strategy, capital management, liquidity and funding and future profitability; and (v) statements of assumptions underlying such statements. Words such as “may”, “will”, “anticipate”, “assume”, “should”, “support”, “indicate”, “would”, “believe”, “contemplate”, “expect”, “estimate”, “continue”, “further”, “plan”, “point to”, “project”, “could”, “intend”, “target” and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Prospective investors are cautioned that any such forward-looking statements are not guarantees of future performance and involve known and unknown risks and uncertainties. Factors that might cause such differences include, but are not limited to: the impact of current and economic conditions, particularly those affecting the financial services industry, including the effects of declines in the real estate market, high unemployment rates, inflationary pressures, elevated interest rates and slowdowns in economic growth, as well as the financial stress on borrowers as a result of the foregoing; the risk of potential reductions in benchmark interest rates and the resulting impacts on net interest income; potential impacts of adverse developments in the banking industry highlighted by high-profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto; risks arising from media coverage of the banking industry; risks arising from perceived instability in the banking sector; the risks of changes in interest rates and their effects on the level, cost, and composition of, and competition for, deposits, loan demand and timing of payments, the values of loan collateral, securities, and interest sensitive assets and liabilities; the ability to attract new or retain existing deposits, to retain or grow loans or additional interest and fee income, or to control noninterest expense; the effect of pricing pressures on the Company’s net interest margin; the failure of assumptions underlying the establishment of reserves for possible credit losses, fair value for loans and other real estate owned; changes in real estate values; the Company’s ability to implement its various strategic and growth initiatives; increased competition in the financial services industry, particularly from regional and national institutions, as well as from fintech companies; economic conditions, either nationally or locally, in areas in which the Company conducts operations being less favorable than expected; changes in the prices, values and sales volumes of residential and commercial real estate; developments in our mortgage banking business, including loan modifications, general demand, and the effects of judicial or regulatory requirements or guidance; legislation or regulatory changes which adversely affect the ability of the consolidated Company to conduct business combinations or new operations; adverse results from current or future litigation, regulatory examinations or other legal and/or regulatory actions, including as a result of the Company's participation in and execution of government programs; significant turbulence or a disruption in the capital or financial markets and the effect of a fall in stock market prices on our investment securities; the effects of war or other conflicts including the impacts related to or resulting from Russia’s military action in Ukraine or the conflict in Israel and surrounding areas; risks related to the Company’s recently completed acquisitions, including that the anticipated benefits from the recently completed acquisitions are not realized in the time frame anticipated or at all as a result of changes in general economic and market conditions or other unexpected factors or events; the risks associated with the Company’s pursuit of future acquisitions; the impact of generative artificial intelligence; fraud or misconduct by internal or external actors, and system failures, cybersecurity threats or security breaches and the cost of defending against them; a deterioration of the credit rating for U.S. long-term sovereign debt, actions that the U.S. government may take to avoid exceeding the debt ceiling, and uncertainties surrounding debt ceiling and the federal budget; a potential U.S. federal government shutdown and the resulting impacts; and general competitive, economic, political and market conditions or other unexpected factors or events. These and other factors, risks and uncertainties could cause the actual results, performance or achievements of the Company to be materially different from the future results, performance or achievements expressed or implied by such forward-looking statements. Many of these factors are beyond the Company’s ability to control or predict. Forward-looking statements speak only as of the date on which such statements are made. These forward-looking statements are based upon information presently known to the Company’s management and are inherently subjective, uncertain and subject to change due to any number of risks and uncertainties, including, without limitation, the risks and other factors set forth in the Company’s filings with the Securities and Exchange Commission, the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, under the captions “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors,” and in the Company’s quarterly reports on Form 10-Q and current reports on Form 8-K. The Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made, or to reflect the occurrence of unanticipated events. Readers are cautioned not to place undue reliance on these forward- looking statements.

3 NON-GAAP FINANCIAL MEASURES Statements included in this presentation include non-GAAP financial measures and should be read along with the accompanying tables, which provide a reconciliation of non-GAAP financial measure to GAAP financial measures. The non-GAAP financial measures used in this presentation include the following: operating noninterest income, operating noninterest expense, operating net income, adjusted earnings per diluted share, operating return on average assets, operating return on average equity, tangible book value per common share, tangible equity to tangible assets, operating efficiency ratio, operating net noninterest expense to average assets and pre-provision net revenue. The most comparable GAAP measures are noninterest income, noninterest expense, net income, diluted earnings per share, return on average assets, return on average equity, book value per common share, total equity to total assets, efficiency ratio, net noninterest expense to average assets and net interest income before provision for credit losses, respectively. Operating noninterest income excludes gain on sale of bank premises and loss on sales of securities. Operating noninterest expense excludes acquisition-related expenses and severance costs. Operating net income, operating return on average assets, operating return on average equity and operating efficiency ratio all exclude acquisition-related expenses, severance costs, gain on sale of bank premises and loss on sales of securities from net income, return on average assets, return on average equity and efficiency ratio, respectively. Operating net noninterest expense to average assets ratio excludes from net noninterest expense, severance costs, acquisition-related expenses, gain on sale of bank premises and loss on sales of securities. Acquisition-related expenses includes fees associated with acquisitions and vendor contract buyouts. Severance costs includes costs associated with termination and retirement of employees. Adjusted earnings per diluted share includes the adjustments to operating net income. Tangible book value per common share and tangible equity to tangible assets exclude goodwill and other intangibles from book value per common share and total equity to total assets, respectively. Pre-provision net revenue is calculated by adding noninterest income to net interest income before provision for credit losses, and subtracting noninterest expense. Management uses these non-GAAP financial measures in its analysis of the Company's performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance, and if not provided would be requested by the investor community. The Company believes the non-GAAP measures enhance investors' understanding of the Company's business and performance. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. Non-GAAP financial measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider Colony Bankcorp, Inc. performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of Colony Bankcorp, Inc. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the results or financial condition as reported under GAAP.
