CULLEN/FROST BANKERS, INC. 8-K

What Happened

• Cullen/Frost Bankers, Inc. (CFR) filed an 8-K reporting that Dr. Chris Avery notified the company on January 27, 2026 that he will retire and will not stand for re-election when his term expires at the 2026 Annual Meeting of Shareholders currently scheduled for April 29, 2026.
• On January 28, 2026 the Board expanded from 13 to 15 members and elected Marsha M. Shields and Jeffrey M. Rummel as directors, effective immediately. The Board determined both are independent under NYSE standards and Rule 10A-3.

Key Details

• Dates: Dr. Avery notified the company on Jan 27, 2026; Shields and Rummel were elected Jan 28, 2026; 2026 Annual Meeting currently scheduled for Apr 29, 2026.
• Board size changed from 13 to 15 members.
• Committee assignments: Both new directors will serve on the Board’s Audit and Risk Committees.
• Backgrounds: Marsha M. Shields is CEO & Managing Partner of McCombs Enterprises and active in philanthropic and healthcare boards. Jeffrey M. Rummel served as San Antonio Office Managing Partner of Ernst & Young through June 2025 with ~37 years at EY and extensive audit experience at large financial institutions.
• Related-party note: Mrs. Shields has ownership interests in entities that had ordinary-course banking transactions with Cullen/Frost in 2025 and are expected to transact in 2026; the Board nonetheless deemed her independent.

Why It Matters

• Board composition and governance: Adding two independent directors with audit and risk expertise strengthens oversight, especially for audit and risk committees that oversee financial reporting and compliance.
• Transition timing: Dr. Avery’s retirement will occur at the 2026 Annual Meeting, so investors should expect the Board change to be finalized then and note the immediate expansion and appointments already took effect.
• Potential related-party activity: The filing discloses ordinary-course banking relationships involving entities tied to Mrs. Shields; investors should be aware these relationships exist but the Board has concluded independence standards are met.
