General

FS Bancorp, a Washington corporation, was organized in September 2011 for the purpose of becoming the holding company of 1st Security Bank upon the Bank’s conversion from a mutual to a stock savings bank (“Conversion”). The Conversion was completed on July 9, 2012. At December 31, 2025, the Company had consolidated total assets of $3.2 billion, total loans receivable, net of $2.62 billion, total deposits of $2.67 billion, and total stockholders’ equity of $307.7 million. The Company has not engaged in significant activities other than holding the stock of the Bank and providing capital to it through the debt and equity markets. Accordingly, the information set forth in this Form 10–K, including the consolidated financial statements and related data, relates primarily to the Bank.

​

1st Security Bank is a relationship-focused community bank dedicated to serving local families, regional businesses, and industry niches primarily within distinct Puget Sound and Pacific Northwest communities. The Bank prioritizes long-term relationships, working closely with customers to meet their financial needs while actively participating in community activities and events to further strengthen these connections.

1st Security Bank has been serving the Puget Sound area since 1907, including the period during which the predecessor to Anchor Bank, one of its banking acquisitions, was formed. The Bank was originally chartered as a credit union, under the name Washington’s Credit Union and primarily served select employment groups. On April 1, 2004, the Bank converted from a credit union to a Washington state-chartered mutual savings bank. Upon completion of the Conversion in July 2012, 1st Security Bank became a Washington state-chartered stock savings bank and a wholly-owned subsidiary of the Company.

At December 31, 2025, the Company maintained its headquarters, which produces loans and accepts deposits, in Mountlake Terrace, Washington, and an administrative office in Aberdeen, Washington. The Bank also operates 27 full-service bank branches, of which 22 are located in Washington state and five in Oregon state, and 13 loan production offices in suburban communities in the greater Puget Sound and Pacific Northwest area. Among the 22 full-service branches in Washington, three are in Snohomish County, two in King County, two in Clallam County, two in Jefferson County, two in Pierce County, five in Grays Harbor County, two in Thurston County, two in Kitsap County, and two in Klickitat County. Furthermore, five full-service branches are located in Oregon: two in Lincoln County, two in Tillamook County, and one in Malheur County. Our 13 loan production offices include seven stand-alone offices: two in Pierce County, one in King County, one in Kitsap County, and one in Snohomish County in the Puget Sound region, as well as one in Benton County in Eastern Washington, and our newest office in Clark County, in Southwest Washington.

The Company is a diversified lender that specializes in originating various types of loans, including commercial real estate (“CRE”), multi-family, construction, one-to-four-family, and home equity loans, as well as consumer loans, such as indirect home improvement (“fixture secured loans”), and marine loans, along with commercial business loans. The Company’s lending strategies aim to capitalize on new lending opportunities, arising from recent market consolidation, and focus on relationship lending. Retail deposits will remain a crucial funding source for the Company. For more detailed information about 1st Security Bank's business and operations, please refer to “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Form 10–K.

The Company has strategically pursued acquisitions, including whole bank acquisitions and branch purchases, to expand its customer base and enhance its distribution network. On February 24, 2023, the Company completed its purchase of seven retail bank branches from Columbia State Bank (the “Branch Acquisition”), adding approximately $425.5 million in deposits and $66.1 million in loans. The acquired branches are located in Goldendale and White Salmon, Washington, as well as Manzanita, Newport, Ontario, Tillamook, and Waldport, Oregon. The Branch Acquisition expanded our Puget Sound-focused retail footprint into southeastern Washington and Oregon, providing an opportunity to introduce its relationship-focused community banking model to these new markets.

1st Security Bank is examined and regulated by the Washington State Department of Financial Institutions (“DFI”), its primary regulator, and by the Federal Deposit Insurance Corporation (“FDIC”). 1st Security Bank is required to have certain reserves set by the Federal Reserve and is a member of the Federal Home Loan Bank of Des Moines (“FHLB” or “FHLB of Des Moines”), which is one of the 11 regional banks in the Federal Home Loan Bank System.
