On July 23, 2025, BankUnited, Inc. (the “Company”) announced the hiring of James G. Mackey as a Senior Executive Vice President of Finance, effective as of August 15, 2025. Mr. Mackey is expected to succeed Leslie N. Lunak as Chief Financial Officer of the Company, effective as of November 1, 2025.

Mr. Mackey, 57, served as Senior Vice President and Chief Financial Officer of VIP Play, Inc., an innovative start-up company in the mobile sports gaming sector, from 2024 through August 2025. From 2020 through 2024, Mr. Mackey served as Executive Vice President and Chief Financial Officer of Wells Fargo’s consumer lending division, where he led the finance team supporting the newly formed division. His responsibilities included supporting strategic initiatives to optimize earnings, minimize operational risk, and increase enterprise value. From 2019 through 2020, Mr. Mackey served as Senior Advisor for the Federal Home Loan Mortgage Corporation (“FHLMC”), following his tenure as Chief Financial Officer of FHLMC from 2013 through 2019. As CFO, Mr. Mackey helped guide the strategic execution of an enterprise-wide transformation, implemented an updated capital management framework, and had a leadership role in initiatives to improve the overall housing finance system. From 2010 through 2013, Mr. Mackey served as Chief Financial Officer and Executive Vice President of Ally Financial where he previously held the position of Senior Finance Executive and Vice President from 2009 to 2010. From 1998 to 2009, Mr. Mackey served in various roles at Bank of America. Mr. Mackey began his career at PwC and holds a master’s degree in accounting and a bachelor’s degree in business administration from the Kenan-Flagler Business School at the University of North Carolina at Chapel Hill.

In connection with Mr. Mackey’s hiring, the Company and Mr. Mackey entered into an offer letter pursuant to which Mr. Mackey’s annual base salary will be $600,000, his target annual bonus opportunity will be $600,000 (prorated for 2025 based on his hire date) and his target annual equity award opportunity will be $800,000 (prorated for 2025 based on his hire date). In addition, in connection with his hire, Mr. Mackey will receive a restricted stock unit award with a grant date value of $1,000,000, 1/3 of which will vest on each of the first three anniversaries of the grant date, and a one-time relocation bonus of $150,000. If Mr. Mackey’s employment is involuntarily terminated without cause not in connection with a change in control, he will be eligible for severance benefits of six months base salary and six months of COBRA premiums, subject to his execution of a release of claims.

The Company and Mr. Mackey also entered into a retention letter providing for the opportunity to receive a retention bonus in the event of a change in control of the Company. If Mr. Mackey remains employed with the Company or its successor six months following a change in control, he will be eligible for a retention bonus equal to (a) three times his annual base salary, if the change in control occurs prior to the first anniversary of his continuous employment with the Company, (b) two times his annual base salary if the change in control occurs on or after the first anniversary of his continuous employment with the Company and prior to the second anniversary of his continuous employment with the Company or (c) one times his annual base salary if the change in control occurs on or after the second anniversary of his continuous employment with the Company. Mr. Mackey will also be eligible for the retention bonus if his employment is terminated without cause or due to a reduction in his base salary between the change in control and the date the retention bonus vests, subject to his execution of a release of claims.
