Kroll Bond Rating Agency (KBRA) assigns a senior unsecured debt rating of BBB, a subordinated debt rating of BBB-, and a short-term debt rating of K3 for Mountlake Terrace, Washington-based FS Bancorp, Inc. (NASDAQ: FSBW) (“the company”). In addition, KBRA assigns deposit and senior unsecured debt ratings of BBB+, a subordinated debt rating of BBB, and short-term deposit and debt ratings of K2 for the subsidiary bank, 1st Security Bank of Washington. The Outlook for all long-term ratings is Stable.

The ratings are supported by the company’s strong earnings performance in recent years, benefitting from its above-average margins and noninterest income contribution. With a meaningful boost from higher-yielding consumer loans, FSBW’s average loan yields (5.14% for 4Q20, and over 6% for 2019) have trended well above peer averages, largely offsetting the company’s comparatively higher funding costs. While high average loan yields portend a potentially higher risk loan portfolio, FSBW has reflected a favorable asset quality history and manageable credit costs, demonstrating capable underwriting (particularly on a risk adjusted basis). Nonetheless, with loans comprising over 85% of AEA and the noted +20% of consumer, KBRA considers the potential risk associated with FSBW’s balance sheet to be greater than that of higher rated peers. Positively, the company has historically maintained solid core capital levels - +10% TCE and +12% CET1 – which remains an important element of a stable creditor profile. Having operated as a credit union for the bulk of its history, FSBW’s funding includes an elevated level of higher cost time deposits (30% of total balances at 4Q20), resulting in above average deposit costs (estimated 0.78% for 2020, down from 1.21% in 2019). Noninterest income has historically represented firmly more than 20% of company core revenues, having increased to over 40% in 2020, because of a very favorable mortgage banking environment. Outside of large but variable gain on sale revenues, net MSR and service fees remain modest.
