Darren King, a senior executive vice president at M&T who served as CFO from 2016 until last year, is leaving the Buffalo, New York-based lender, effective Aug. 10, the bank disclosed Wednesday.

The bank did not offer details in a Securities and Exchange Commission filing indicating that King “will separate from the Company” without citing any specific reason for the departure or saying who would replace King.

However, Frank Lentini, M&T Bank’s senior communications director, told Banking Dive that King will “leave the company for personal reasons.”

“We appreciate the contributions that Darren has made across the organization during his tenure,” Lentini wrote Thursday in an email.

The SEC filing did not indicate who would take up King’s responsibilities. Lentini, for his part, said Rich McCarthy remains head of retail banking, and Eric Feldstein remains head of business banking. 

“These businesses, under their leadership, will continue to serve our customers and employees,” Lentini said.

King is a 24-year veteran of M&T, joining in 2000. He succeeded now-CEO René Jones as CFO in 2016.

King moved into a role overseeing retail and business banking, and mortgage and consumer lending when M&T hired Truist alum Daryl Bible to serve as CFO. Bible’s experience merging the former BB&T and Truist in 2019 was seen as a plus for M&T in 2023, when it was onboarding People’s United. 

Before becoming the CFO in 2016, King was the retail-banking executive overseeing business banking functions for M&T’s branch and ATM network, according to the company. He also supervised the bank’s marketing and communications division.

Prior to joining M&T, he held senior leadership roles, including vice president of the financial services practice, at Mercer Management Consulting, the predecessor firm to Oliver Wyman, according to an earlier SEC filing. 

M&T lost another high-ranking executive last year, when the bank’s president and chief operating officer, Rich Gold, retired. That role has yet to be filled.
