Marathon Bancorp just closed its first full fiscal year as a fully public stock company, and the income statement finally looks like a bank rather than a conversion leftover. The April 2025 second-step conversion put fresh capital on the balance sheet and listed the shares on Nasdaq. The year ended in June then delivered the first clean read on whether that capital earns its keep. Net income jumped from a near-breakeven print to almost two million, driven by a wider net interest margin and an earning-asset mix that now leans commercial and multifamily rather than a classic thrift mortgage book.
The market has already moved. Shares sit near the top of the past-year range and above the ten-dollar conversion price, which means a large slice of the mechanical re-rating that usually follows a second-step offering is behind the tape. Book value still exceeds the share price, so the equity is not expensive on a franchise-value screen. Trailing earnings, however, remain thin relative to the capital base, and the multiple on those earnings is high precisely because the numerator only just turned on.
The debate is therefore about durability, not about whether last year improved. Three variables decide it. First, whether the expanded net interest margin holds as certificates of deposit reprice and Federal Home Loan Bank advances stay in the funding mix. Second, whether core deposits in Wausau and the Milwaukee suburbs grow fast enough to fund the commercial book without more wholesale money. Third, whether a loan book now dominated by commercial and multifamily real estate stays as clean as the current nonaccrual tape. A first post-conversion repurchase authorization of roughly five percent of the share count is the capital-return signal; there is still no dividend.
