Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statement of financial condition of CB Financial Services, Inc. (Company) as of December 31, 2023 and 2022, and the related consolidated statements of income, comprehensive income (loss), changes in stockholders’ equity, and cash flows for the years ended December 31, 2023 and 2022, and the related notes (collectively referred to as the “financial statements”). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 1 and Note 4 to the consolidated financial statements, in 2023, the entity changed its method of accounting for credit losses on financial instruments due to the adoption of Accounting Standards Codification Topic 326: Financial Instruments – Credit Losses.

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 the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include 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 (ACL) – Qualitative Adjustments

As described in Notes 1 and 4 to the consolidated financial statements and referred to in the change in accounting principle explanatory paragraph above, the Company adopted ASC 326 as of January 1, 2023, which among other things, required the Company to recognize expected credit losses over the contractual lives of financial assets carried at amortized costs, including loans receivables, utilizing the Current Expected Credit Losses (“CECL”) methodology. As of December 31, 2023, the allowance for credit losses (ACL) balance was $9,707,000. Estimates of expected credit losses are based on relevant information about current conditions, past events, and reasonable and supportable forward-looking forecasts regarding collectability of the reported amounts. The Company utilized a discounted cash-flow model derived from historical data to construct a loss rate for each identified loan segment. Due to the Company's loss history not being sufficient and relevant enough to predict future losses, the Company also utilized peer data from a peer group. The loss rates are then adjusted, for reasonable and supportable forecasts of relevant economic indicators as well as other environmental factors based on the risks present for each portfolio segment. The environmental factors (“qualitative adjustments”) include consideration of economic conditions and portfolio trends.

We have identified auditing the qualitative adjustments as a critical audit matter as management’s determination of the qualitative adjustments used in the ACL is subjective and involves significant management judgments; and our audit procedures related to the qualitative adjustments involved a high degree of auditor judgment and required significant audit effort, including the need to involve more experienced audit personnel.

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

•Substantively testing management's determination of the qualitative adjustments used in the ACL estimate, including:

◦Testing management’s process for developing the qualitative adjustments, which included assessing the relevance and reliability of data used to develop the qualitative adjustments, including evaluating their judgments and assumptions for reasonableness. Among other procedures, our evaluation considered evidence from internal and external sources.

◦Analytically evaluating the qualitative adjustments for directional consistency, testing for reasonableness, and obtaining evidence for significant changes.

◦Testing the mathematical accuracy of the qualitative adjustments applied to the loan segments in the ACL calculation.
