Organization, Consolidation and Presentation of Financial Statements [Abstract] |
General | 1. GENERAL First US Bancshares, Inc., a Delaware corporation (“Bancshares” and, together with its subsidiary, the “Company”), is a bank holding company formed in 1983 registered under the Bank Holding Company Act of 1956, as amended (the “BHCA”). Bancshares operates one wholly owned banking subsidiary, First US Bank, an Alabama banking corporation (the “Bank”). Bancshares and the Bank are headquartered in Birmingham, Alabama. The Bank conducts a general commercial banking business and offers banking services such as demand, savings, individual retirement account and time deposits, personal and commercial loans, safe deposit box services and remote deposit capture. The Bank operates and serves its customers through 15 full-service banking offices located in Birmingham, Butler, Calera, Centreville, Gilbertown, Grove Hill, Harpersville, Jackson, Thomasville, Tuscaloosa and Woodstock, Alabama; Knoxville and Powell, Tennessee; and Rose Hill, Virginia; as well as loan production offices in Mobile, Alabama and the Chattanooga, Tennessee area. The Bank provides a wide range of commercial banking services to small- and medium-sized businesses, property managers, business executives, professionals and other individuals. The Bank also performs indirect lending through third-party retailers and currently conducts this lending in 17 states, including Alabama, Arkansas, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Mississippi, Missouri, Nebraska, North Carolina, Oklahoma, South Carolina, Tennessee, Texas and Virginia. The Bank is the Company’s only reportable operating segment upon which management makes decisions regarding how to allocate resources and assess performance. The unaudited interim condensed consolidated financial statements, in the opinion of management, reflect all adjustments necessary for a fair presentation of the Company’s consolidated financial position, results of operations and cash flows for the periods presented. Such adjustments are of a normal, recurring nature. The results of operations for any interim period are not necessarily indicative of results expected for the fiscal year ending December 31, 2025. While certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”), management believes that the disclosures herein are adequate to make the information presented not misleading. These unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K as of and for the year ended December 31, 2024 (the "Company's 2024 Form 10-K").
