AI brief of an SEC Form 8-K · BankUnited (BKU)

BankUnited CFO Leslie Lunak steps down, becomes Executive Advisor through January 2026

Neutral Impact 4 of 5 leadership Written later

BankUnited said former Chief Financial Officer Leslie Lunak stepped down on November 10, 2025, and will serve as Executive Advisor until January 2, 2026, then as a non-employee Special Advisor through December 31, 2027, under a transition letter dated November 19, 2025. The change in the top finance role is significant for shareholders, though the filing does not report financial results or name a successor.

Key points

  • Lunak stepped down as CFO on November 10, 2025; her Executive Advisor role runs through January 2, 2026.
  • From January 3, 2026 to December 31, 2027, she serves as a non-employee Special Advisor.
  • Her outstanding performance share units remain eligible to vest on actual performance, and she agreed to non-compete and non-solicitation covenants through December 31, 2027.
  • Certain payments are conditional: if the company terminates her without cause before January 2, 2026, she keeps equity vesting and her 2025 incentive award, subject to compliance.
