SPRINGFIELD, Missouri — Great Southern Bancorp Inc. (GSBC) disclosed that director William Turner resigned from its board of directors, effective May 13 2026.

The resignation affects the 11-member board that oversees the $5.8 billion-asset bank holding company and its subsidiary Great Southern Bank, which operates 93 branches across Missouri, Arkansas, Oklahoma, Kansas and Nebraska. Turner had served on the board since 2004 and participated in its audit, compensation, and nominating committees, per the company's most recent proxy statement.

Prior to the filing the board consisted of 11 directors. The new state leaves 10 directors in place. The change took effect immediately on May 13 2026, the date stated in the 8-K filed with the SEC on May 15 2026. The filing does not name a successor or indicate whether the board size will be reduced permanently.

The departure initiates several operational requirements. The company must update its disclosures on director composition in its next quarterly report or proxy statement. Nasdaq listing rules require the board to maintain a majority of independent directors and fully independent audit and compensation committees; the company will need to confirm compliance in its next Form 10-Q or 10-K.

If the board elects a new director, that individual must complete required regulatory background checks with the Federal Reserve and Missouri Division of Finance before assuming the role. The resignation also ends Turner's participation in any existing director indemnification agreements and equity awards that vest on a continuing-service basis.

This marks the first board-level change reported by Great Southern Bancorp since its 2024 proxy season. The company last filed an 8-K concerning director or officer matters in 2023 when it elected a new independent director. Item 5.07 of the same May 15 2026 filing also reported results of the annual shareholder meeting held that day, though specific vote tallies were not detailed in the structured data.
