(the “Company”), a stock holding company, and its wholly-owned subsidiary, Rhinebeck Bank (the “Bank”), a New York chartered stock savings bank. The primary purpose of the Company is to act as a holding company for the Bank. The Bank provides a full range of banking and financial services to consumer and commercial customers through its twelve branches and two representative offices located in Dutchess, Ulster, Orange, and Albany counties. Financial services, including investment advisory and financial product sales, are offered through a division of the Bank doing business as Rhinebeck Asset Management. The unaudited consolidated financial statements reflect all adjustments, which in the opinion of management are necessary for a fair presentation of the results of the interim periods and are of a normal and recurring nature. Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026 or for any other period. The unaudited financial statements and other financial information contained in this Quarterly Report on Form 10-Q should be read in conjunction with the audited financial statements, and related notes, of the Company at and for the year ended December 31, 2025 contained in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on March 13, 2026 (the “Annual Report on Form 10-K”). For more information regarding the Company’s significant accounting policies, see the Notes to the Consolidated Financial Statements in the Annual Report on Form 10-K. As of March 31, 2026, the critical accounting policies of the Company have not changed materially from those disclosed in the Annual Report on Form 10-K. See Note 1 of the Consolidated Financial Statements – Nature of Business and Significant Accounting Policies. Basis of Financial Statements Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and general practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities, as of the date of the consolidated statements of financial condition and reported amounts of revenues and expenses for the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses (“ACL”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain amounts in the prior year consolidated financial statements may be reclassified as required to conform to the current year’s presentation. These reclassifications have no effect on our previously reported net income or stockholders’ equity. Impact of Recent Accounting Pronouncements In October 2023, the FASB issued ASU 2023-06, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. In annual periods, this requires disclosure of an entity’s accounting policy related to where in the statement of cash flows the entity presents cash flows associated with derivative instruments and the related gains and losses. This also requires disclosure of the methods used in the diluted earnings per share computation for each dilutive security and clarifies that certain disclosures should be made during interim periods. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The Company is evaluating the impact of this ASU but does not expect it to have a material impact on the Company’s consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures,” which requires disaggregated disclosure of income statement expenses for public business entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. The ASU requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense captions. The guidance will be effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, ASU 2024-03 may be applied prospectively or retrospectively. The Company is evaluating the impact of this ASU but does not expect it to have a material impact on the Company’s consolidated financial statements. In November 2025, the FASB issued ASU 2025-08, “Financial Instruments—Credit Losses (Topic 326): Purchased Loans,” which amends the accounting for acquired loans by introducing a category of purchased seasoned loans and expanding the use of the gross-up approach, requiring qualifying acquired loans to be recorded at purchase price plus an allowance for expected credit losses rather than recognizing a Day-1 provision through earnings. ASU 2025-08 is effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual periods, and is to be applied prospectively, with early adoption permitted. The Company is evaluating the impact of this ASU but does not expect it to have a material impact on the Company’s consolidated financial statements. In November 2025, the FASB issued ASU 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements,” which updates the hedge accounting guidance to improve alignment between hedge accounting and an entity’s risk management activities and to clarify and simplify the application of certain hedge accounting requirements. ASU 2025-09 is effective for annual reporting periods beginning after December 15, 2026, including interim periods within those annual reporting periods, with early adoption permitted. The Company is evaluating the impact of this ASU but does not expect it to have a material impact on the Company’s consolidated financial statements.
