Marathon Bancorp’s QQ4 2024 results show a modest revenue uplift on a YoY basis but a dramatic swing in quarterly profitability driven by cost structure and a very large investment positioning. Revenue reached 2.48 million, up 21.1% year over year, while net income posted 85,836, down 82.6% from the prior-year quarter, reflecting a much weaker bottom-line despite an improving quarter-on-quarter trajectory (net income up 113.6% QoQ from Q3 2024). The company maintains a substantial investment portfolio (long-term investments around 184 million) and a high level of other current liabilities, resulting in a fragile near-term liquidity dynamic on traditional current-ratio metrics. On a per-share basis, diluted EPS was 0.040, with a 0.04% quarterly earnings cadence, underscoring a company that trades at a significant premium to earnings given a P/E of approximately 41x and a price-to-book of ~0.45x. The quarter signals balance-sheet resilience through capital and liquidity tied to investment holdings, but profitability metrics remain weak versus peers, and near-term liquidity and loan-deposit dynamics merit close monitoring. Investors should weigh the potential upside from ongoing investment income and capital deployment against structural profitability and liquidity challenges. Long-run value creation will hinge on improving return metrics (ROA/ROE) and enhancing operating efficiency while managing credit risk in a regional credit cycle. Ultimately, MBBC appears to be a lender with an outsized securities position, trading at a discounted book multiple but with meaningful earnings volatility and balance-sheet concentration risk that require vigilant monitoring.
