EWSB Bancorp, Inc. is a Maryland corporation that owns 100 percent of the outstanding common stock of East Wisconsin Savings Bank. The company operates as a bank holding company and conducts its primary business through its subsidiary bank. East Wisconsin Savings Bank is a Wisconsin chartered stock savings bank that accepts deposits from the public and uses those funds to originate loans and invest in securities. The bank’s lending activities focus on one to four family residential real estate loans, marine and recreational vehicle loans, home equity loans and lines of credit, construction loans, and other consumer loans. It also originates a smaller volume of commercial real estate, multifamily, and commercial loans. In addition to lending, the bank invests in United States Treasury securities, federal agency securities, municipal bonds and corporate bonds. The company is headquartered in Kaukauna, Wisconsin and serves customers primarily in Outagamie County and surrounding areas. The bank also provides traditional banking services such as issuing debit cards, processing automated clearing house transactions and offering online banking platforms.
Revenue is generated primarily from interest income on the loan portfolio and on investment securities. The bank earns interest on residential mortgages, marine and recreational vehicle loans, home equity lines, construction loans, and other consumer loans. Additional interest income comes from commercial loans and from securities such as Treasury notes, agency mortgage backed securities and corporate bonds. The bank also collects fees on deposit accounts, including service charges on checking and savings accounts, and earns income from loan related activities such as origination fees and late charges. While a portion of longer term fixed rate residential mortgages is sold on a servicing retained basis, the bank retains interest income on the loans it holds in portfolio. Overall, the mix of interest income and fee income constitutes the company’s revenue stream. The bank’s net interest income, which reflects the difference between yield on earning assets and cost of funds, remains a key indicator of profitability.
East Wisconsin Savings Bank operates in a competitive market that includes large national banks, regional banks, community banks and credit unions. According to FDIC data for June 2025, the bank held 5.2 percent of the insured deposit market share in Outagamie County, ranking it as the eighth largest among nineteen banks operating there. The bank differentiates itself through its long standing presence since 1887, its focus on relationship banking and its deep knowledge of the local economy. Its diversified loan portfolio, which balances residential mortgage lending with niche areas such as marine and recreational vehicle financing, helps reduce reliance on any single product line. The bank’s conservative underwriting standards and its emphasis on maintaining adequate capital and liquidity also support its competitive stance. Management emphasizes disciplined expense control and efficient branch operations to maintain competitiveness against larger institutions that benefit from greater scale.
The bank’s customer base consists mainly of individuals and households residing in Outagamie County and nearby communities. Retail customers include homeowners seeking mortgages, owners of boats and recreational vehicles, and consumers obtaining personal or auto loans. Small businesses and professionals in the area also receive commercial loans and lines of credit. While the filing does not list specific customer names, the bank serves a broad mix of retail and commercial clients who value local decision making and personalized service. Deposit growth is driven by attracting core checking and savings accounts from local residents who prefer the convenience of neighborhood branches.
