Summary of significant accounting policies |
Nature of operations | Nature of operations ​ Peoples Financial Services Corp., a bank holding company incorporated under the laws of Pennsylvania, provides a full range of financial services through its wholly owned direct and indirect subsidiaries, including Peoples Security Bank and Trust Company (the “Bank”) and 1st Equipment Finance, Inc., collectively, the “Company” or “Peoples”. The Company services its retail and commercial customers through forty full-service community banking offices located within Allegheny, Bucks, Lackawanna, Lancaster, Lebanon, Lehigh, Luzerne, Monroe, Montgomery, Northampton, Susquehanna, and Wyoming Counties of Pennsylvania, Middlesex County of New Jersey, and Broome County of New York.
Basis of presentation | Basis of presentation ​ The accompanying unaudited interim consolidated financial statements of the Company have been prepared in accordance with the instructions to Form 10-Q and Article 10-01 of Regulation S-X and accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and results of operations for the periods presented have been included. All significant intercompany balances and transactions have been eliminated in consolidation. Prior period amounts are reclassified when necessary to conform to the current year’s presentation. These reclassifications did not have any effect on the consolidated operating results or financial position of the Company. ​ The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates that are particularly susceptible to material change in the near term relate to the determination of the allowance for credit losses and impairment of goodwill. Actual results could differ from those estimates. ​ These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.
Subsequent events | Subsequent events ​ The Company has evaluated events and transactions occurring subsequent to the balance sheet date of June 30, 2026, for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the issuance date of these consolidated financial statements. ​ On July 31, 2026, the Company’s board of directors declared a dividend of $0.6250 per share for the third quarter of 2026. The dividend is payable on September 15, 2026 to shareholders of record as of August 31, 2026. The per share dividend is equal to the per share dividend declared for the second quarter of 2026.
Recent accounting standards | Recent accounting standards ​ From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the required effective dates. The following should be read in conjunction with Note 1 entitled “Summary of significant accounting policies” of the Notes to the Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. ​ ASU 2026-02, “Environmental Credit and Environmental Credit Obligations (Topic 818)” is intended to address the lack of specific U.S. GAAP guidance on environmental credits and environmental credit obligations. ASU 2026-02 aims to improve recognition, measurement, presentation and disclosure of these items and enhance comparability and decision-useful information for investors. The ASU requires entities to clearly present environmental credits and credit obligations in financial statements, distinguishing between compliance and noncompliance credits, providing disclosures that improve understandability and comparability. ASU 2026-02 is effective for public business entities for annual periods beginning after December 15, 2027, including interim periods, and permits early adoption at the start of any annual period. ASU 2026-02 will be effective on January 1, 2028, for the Company’s quarterly financial statements on Form 10-Q and is not expected to have a material impact on the Company’s consolidated financial statements. ​ ASU 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements” is intended to improve the navigability and clarity of interim reporting requirements under Topic 270. ASU 2025-11 clarifies when Topic 270 applies, adds a comprehensive list of required interim disclosures, and introduces a disclosure principle requiring entities to disclose events occurring after the most recent annual period that have a material impact on the entity. The ASU does not expand or reduce overall interim disclosure requirements but instead compiles and organizes them to improve consistency and comparability. The guidance also clarifies form-and-content expectations for interim financial statements, including the use of condensed statements, and aligns GAAP with prior SEC requirements regarding material events. The amendments are effective for interim reporting periods beginning after December 15, 2027, for public business entities and one year later for all other entities. Early adoption is permitted, with prospective or retrospective application available. ASU 2025-11 will be effective for the interim period beginning January 1, 2028, for the Company’s quarterly financial statements on Form 10-Q and is not expected to have a material impact on the Company’s consolidated financial statements. ​ ASU 2025-08 “Financial Instruments – Credit Losses (Topic 326): Purchased Loans” (“ASU 2025-08”) expands the use of the gross up-approach in ASC 326, Credit Losses, to “purchased seasoned loans,” which the guidance defines as loans, excluding purchased financial assets with credit deterioration, credit card receivables, debt securities, and trade receivables, that are (1) acquired in a business combination or (2) obtained through a transfer that is not a business combination or initially recognized through the consolidation of a variable interest entity, if certain seasoning criteria are met. This approach was previously only applied to purchased financial assets with credit deterioration. The guidance is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. Entities are required to apply the guidance prospectively. Early adoption is permitted. The Company is currently in the process of evaluating this guidance. ​ ASU 2025-01 “Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date” (“ASU 2025-01”) clarifies the effective date of Accounting Standards Update 2024-03 “Income Statement Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”) to stipulate that ASU 2024-03 is effective for public business entities for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. ASU 2024-03 will be effective for the Company beginning January 1, 2027, for the Company’s annual financial statements on Form 10-K and January 1, 2028, for the Company’s quarterly financial statements on Form 10-Q and is not expected to have a material impact on the Company’s consolidated financial statements but is expected to result in additional disclosures and potential changes to line items on the consolidated statements of income and comprehensive income.
