Maples Mark A 4

What Happened

• Mark A. Maples, Vice President of a subsidiary of Great Southern Bancorp (GSBC), exercised options to acquire 2,387 shares (1,187 shares at $57.98 and 1,200 shares at $61.55) for a total exercise cost of $142,682, then disposed of 2,387 shares on 2026-05-01.
• He sold 2,387 shares in the open market at $68.95 per share for gross proceeds of $164,596. The filing also shows derivative disposals equal to the exercise amounts, consistent with shares being withheld/surrendered to cover exercise costs and/or tax withholding.
• This sequence (exercise then immediate sale / sell-to-cover) is a liquidity transaction rather than a straightforward buy signal; the open‑market sale produced gross proceeds exceeding the exercise cost by $21,914 (before fees and taxes).
