On December 15, 2025, Talen Energy Corporation (NASDAQ: TLN) announced a realignment of its executive management team as part of ongoing succession and retention planning.
Mac McFarland extended his CEO employment agreement through February 2027, resigned as President, and remains CEO and a Board member. Terry L. Nutt was appointed President and resigned as CFO, but will act as principal financial officer until the annual report for fiscal 2025 is filed.
Cole Muller was appointed CFO, Brad Berryman was appointed Chief Operating Officer, Dale Lebsack was appointed Chief Asset Development Officer, and Ed Casulli was appointed Chief Nuclear Officer, all effective immediately. General Counsel John Wander gave notice of his intent to retire at the end of June 2026. The filing also describes retention measures.
Amended employment agreements for key executives run through February 28, 2027, with automatic annual renewals. Up to 60% of certain 2026-vesting PSUs and RSUs will be settled in cash, subject to a cap tied to a $400a share price and to Compensation Committee discretion, and the resulting shares are locked up through November 13, 2026. The press release states that the cash settlement is expected to have a significant anti-dilutive effect.
Using an illustrative $400b share price, it estimates about $388 million in withholding taxes, $369 million in cash settlement, and about 680,000 shares issued, versus about 2,573,000 shares without the partial cash settlement. Salary and target incentive levels were set for the named executives.
Mr. McFarland's salary is $1,400,000,c Mr. Nutt's is $925,000, Mr. Muller's is $725,000, and Mr. Berryman's is $600,000. Severance terms were also updated, including a 2.99 times salary-plus-target-bonus lump sum for qualifying terminations within 18 months after a change of control, and Mr. McFarland receives 2 times salary-plus-target-bonus for qualifying terminations outside that window.

Frequently Asked Questions
Who is running Talen Energy's day-to-day operations and finances after these changes?

Cole Muller is the new CFO, responsible for accounting, treasury, risk management, financial planning, investor relations, tax, and internal controls. Mac McFarland remains CEO and is focused on strategic direction.
Why is the company settling part of its equity awards in cash?
The filing describes the cash settlement as part of retention planning. Up to 60% of the relevant PSUs and RSUs will be settled in cash, which the press release says is expected to have a significant anti-dilutive effect on the number of shares outstanding. The Compensation Committee may modify the cash-settled portion if it determines the settlement would materially and adversely affect the company.
Will there be any change in CFO-related reporting responsibilities in the near term?
Yes. Mr. Nutt resigned as CFO but will assist with the transition and act as principal financial officer until the company files its annual report for the fiscal year ending December 31, 2025.
What severance protections do the executives have?
For qualifying terminations within 18 months after a change of control, executives receive a lump sum of 2.99 times the sum of annual base salary and target bonus, a pro-rated target bonus, and COBRA continuation for up to 36 months. For qualifying terminations outside that window, the payment is the sum of salary and target bonus paid over 12 months, with Mr. McFarland receiving two times that amount.
What is happening with the General Counsel role?
John Wander, General Counsel and Corporate Secretary, will retire at the end of June 2026 and move to a Senior Advisor role at $12,500 for those services. He will continue overseeing legal functions until retirement, and the company will search for his replacement.
