**PART III — NARRATIVE**

United Security Bancshares (the "Company") was unable to file a Form 11-K for the United Security Bank Cash or Deferred Stock Ownership Plan for the year ended December 31, 2024 in a timely manner without unreasonable effort or expense due to delays in the collection and compilation of certain information from third parties that is required for its independent registered public accounting firm, Baker Tilly US, LLP ("Baker Tilly") to complete its audit procedures. This delay in filing is not the result of any material weakness in the effectiveness of the Company's internal control over financial reporting or any disagreements with Baker Tilly on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure. The Company expects to file the Form 11-K within the extension period provided by Rule 12b-25.
