CB Financial Services, Inc. (Nasdaq: CBFV) October 2026 Page 2 Forward-Looking Statements and Non-GAAP Financial Measures Statements contained in this investor presentation that are not historical facts may constitute forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995 and such forward-looking statements are subject to significant risks and uncertainties. The Company intends such forward-looking statements to be covered by the safe harbor provisions contained in the Act. The Company’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain. Factors which could have a material adverse effect on the operations and future prospects of the Company and its subsidiaries include, but are not limited to, general and local economic conditions, changes in market interest rates, deposit flows, demand for loans, real estate values and competition, competitive products and pricing, the ability of our clients to make scheduled loan payments, loan delinquency rates and trends, our ability to manage the risks involved in our business, our ability to control costs and expenses, inflation, market and monetary fluctuations, changes in federal and state legislation and regulation applicable to our business, actions by our competitors, and other factors that may be disclosed in the Company’s periodic reports as filed with the Securities and Exchange Commission. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. The Company assumes no obligation to update any forward-looking statements except as may be required by applicable law or regulation. Explanation of Use of Non-GAAP Financial Measures In addition to financial measures presented in accordance with generally accepted accounting principles (“GAAP”), we use, and this investor presentation may contain or reference, certain non-GAAP financial measures. We believe these non-GAAP financial measures provide useful information in understanding our underlying results of operations or financial position and our business and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Non-GAAP adjusted items impacting the Company's financial performance are identified to assist investors in providing a complete understanding of factors and trends affecting the Company’s business and in analyzing the Company’s operating results on the same basis as that applied by management. Although we believe that these non-GAAP financial measures enhance the understanding of our business and performance, they should not be considered an alternative to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with similar non-GAAP measures which may be presented by other companies. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found within the referenced earnings release.

CB Financial Services, Inc. (Nasdaq: CBFV) October 2026 Page 7 2026 Macro Outlook Item Comment Monetary Policy Monetary policy remains uncertain as the Federal Reserve balances inflation, economic growth, and employment. Continued focus on disciplined pricing, liquidity, and interest rate risk management will help mitigate potential impacts. Inflation/Demand Inflationary pressures and broader economic uncertainty may affect consumer and business activity, loan demand, and credit performance. Pricing flexibility, cost discipline, and proactive portfolio monitoring remain important. Regulatory Environment The regulatory environment continues to evolve, with increased attention on risk management, cybersecurity, consumer protection, technology, and operational resilience. Strong controls and adaptable compliance practices remain essential. Market Dynamics Competition, changing customer expectations, and emerging technologies continue to reshape financial services. Maintaining strong client relationships while investing thoughtfully in digital capabilities and innovation will support long-term relevance and growth. CB needs to remain vigilant and adaptable to navigate the uncertainties and complexities of the macroeconomic landscape in 2026 and beyond.
