United Security Bancshares has announced a change in its independent registered public accounting firm following a merger. On June 4, 2025, the company was informed that Moss Adams LLP, its previous auditor, merged with Baker Tilly US, LLP as of June 3, 2025. Consequently, Moss Adams resigned as the company's auditor, and the Audit Committee of United Security Bancshares' Board of Directors approved the appointment of Baker Tilly US, LLP as the new auditors. During the past two years and up to this announcement, United Security Bancshares had not consulted with Baker Tilly on accounting principles or audit opinions. Moss Adams' audit reports for 2023 and 2024 did not have any adverse opinions or disagreements with the company. The transition to Baker Tilly is not expected to affect the company's financial reporting.
