MARATHON BANCORP INC

Company Overview

Marathon Bancorp is the mid‑tier holding company for Marathon Bank, a Wisconsin‑chartered community savings bank that converted to a stock holding company in April 2025 (gross proceeds $16.9M; net ~$15.2M) and financed an ESOP participation. The bank operates five locations serving Marathon, Ozaukee and Waukesha counties with expansion into the Milwaukee/Waukesha metro, and its core activities are retail and commercial deposit gathering and deployment into loans and investment securities. At June 30, 2025 consolidated assets were $238.8M, loans $202.6M (concentrated in commercial real estate 45.4%, multifamily 23.6%, and 1–4 family residential 27.8%), deposits $175.2M, and equity $45.7M; it uses FHLB advances ($15.0M outstanding; $82.8M facility available) as supplemental funding. Management emphasizes conservative underwriting (LTVs generally 75–80%, DSC ~1.25x), strong capital/liquidity metrics, and sensitivity to interest rates, deposit flows and CRE concentration.

Executive Compensation Practices

With the April 2025 conversion to a public company and ESOP financing, compensation is likely shifting from private‑company cash emphasis toward more formalized equity‑linked incentives (restricted stock, long‑term awards and ESOP allocations) alongside base salary and cash bonuses. Short‑term bonus metrics for regional banks like Marathon typically link to net interest income, net income/profitability, loan originations and deposit retention; for Marathon specifically, NIM expansion, loan growth in CRE/multifamily, efficiency ratio and credit metrics (NPAs, allowance for credit losses) will be principal drivers. Long‑term pay will likely tie to capital and liquidity measures (well‑capitalized status), return on equity/ROAE or TSR, and asset‑quality improvement given concentration risks. Compensation design must also reflect banking regulatory guidance on sound incentive practices (including clawbacks and risk‑adjusted performance) and the smaller‑staff structure may mean material insider equity concentrations.

Insider Trading Considerations

As a newly converted stock company with ESOP participation, insiders likely received meaningful equity and may be subject to lock‑up/restriction agreements or ESOP vesting schedules that govern timing of sales; conversely, post‑conversion diversification sales are common and can be sizeable relative to float. The company’s small market cap and relatively low float mean individual insider transactions (sales or buys) can move price materially, so monitor Form 4 filings (timely reporting) and any disclosed 10b5‑1 plans. Regulatory and internal blackout periods typical for banks (around earnings, regulatory exams or sensitive deposit/allowance developments) will constrain trading windows, and banks face heightened scrutiny under interagency incentive compensation guidance — particularly when allowance levels, CECL methodology, deposit roll‑offs or CRE concentrations drive material credit or capital changes that affect bonus outcomes.
