Marathon Bancorp CFO to Retire July 2, 2027

What Happened
Marathon Bancorp, Inc. (and its subsidiary Marathon Bank) filed an 8-K on October 1, 2026 reporting that Chief Financial Officer Joy C. Selting‑Buchberger informed the Boards on September 30, 2026 that she will retire as CFO of both the Company and the Bank effective July 2, 2027.

Key Details

• Executive: Joy C. Selting‑Buchberger, Chief Financial Officer of Marathon Bancorp and Marathon Bank.
• Notice date: She notified the Boards on September 30, 2026.
• Effective retirement date: July 2, 2027.
• Filing: The Company reported the departure via a Form 8‑K filed October 1, 2026.

Why It Matters
A CFO departure is a material leadership change because the CFO oversees financial reporting, accounting, and investor communications. The company has provided a long transition window (about nine months), which gives time for succession planning and an orderly handoff—details about a successor or interim arrangements were not included in the 8‑K. Investors should watch for follow-up disclosures about the CFO transition and any impact on financial policies or reporting.
