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

BankUnited names James G. Mackey chief financial officer effective November 10, 2025

Neutral Impact 3 of 5 leadership Written later

BankUnited appointed James G. Mackey as chief financial officer effective November 10, 2025, succeeding Leslie N. Lunak, who had held the CFO role since 2013. Lunak remains with the company as executive advisor through January 2026. The change was previously announced in July 2025, so the filing confirms a planned succession rather than a new development.

Key points

  • Mackey was hired July 23, 2025, and served as senior executive vice president of finance from August 15, 2025, to November 10, 2025.
  • Lunak stepped down as CFO on November 10, 2025, and will continue as executive advisor through January 2026.
  • The company's press release announcing the appointment is furnished as Exhibit 99.1; CEO Rajinder Singh signed the filing.
