GREAT SOUTHERN BANCORP, INC.
Next earnings Jul 15, 2026 · consensus $1.39 EPS, $49.3M rev
Last earnings -1.0% on 2026-04-16
Cheap, well-capitalized community bank with expanding NIM, pristine credit, and aggressive buybacks at 1.34x book — a quiet compounder.
Diluted EPS $6.19 · FY2025
Quality fundamentals and an attractive price line up (~141% below fair value) — the rarer case where both the business and the entry look good.
GSBC is a textbook conservative community bank trading at a discount to its underlying quality. FY2025 net income rebounded 14.8% to $71.0M and diluted EPS jumped 17.7% to $6.19 — a sharper EPS gain than net income because share count fell 5.5% as the company paid $44.5M in buybacks (nearly triple the prior year). At $77.23 the stock trades at just 12.5x earnings and roughly 1.34x the disclosed $57.50 book value per share, which is undemanding for a bank earning an 11.38% return on average equity with a 61.9% efficiency ratio.
The MD&A reveals the operating engine is actually accelerating, not just buyback-engineered. Net interest income rose to $200.2M from $189.1M as net interest margin expanded to 3.67% from 3.42% and the average interest rate spread widened to 3.10% from 2.76% — the franchise is repricing assets faster than deposit costs, with interest expense on deposits actually falling to $94.1M from $109.7M. Asset quality is exceptional: non-performing assets are just 0.18% of loans, allowance covers non-performing loans 30x over, and net charge-offs were effectively zero. The 6.4% asset shrinkage reflects deliberate balance-sheet management (loans receivable down to $4.36B, borrowings cut from $679M to $405M), not stress.
Is GSBC a buy? The one-page verdict, explained →
High-conviction BUY: a wider spread keeps more of the upside while the short call still cuts cost and decay.
Educational template, not a trade recommendation. Strikes and premiums are Black-Scholes model estimates from the last close and 30-day realized volatility — real chains, spreads and IV will differ. Options involve substantial risk.
