Mr. Nutt served as Chief Financial Officer of the Company from July 2023 through his appointment as President. He has over 25 years of experience in the energy industry, including time spent at independent power producers and energy trading firms. From 2018 until 2023, he served as Chief Financial Officer and Managing Director for EDF Trading North America (“EDF”), the energy commodity trading subsidiary of Électricité de France (EDF) S.A., a multinational energy utility headquartered in France. Prior to his service at EDF, Mr. Nutt served in multiple senior finance positions at Vistra Corporation (and its predecessor entities) (“Vistra”), including as Senior Vice President and Controller and Senior Vice President of Risk Management. Prior to his time at Vistra, Mr. Nutt worked in various finance roles at Dynegy Inc. Mr. Nutt earned his M.S. in Accounting and his B.B.A., summa cum laude, from Texas A&M University.

Mr. Muller most recently served as the Company’s Executive Vice President, Strategic Ventures prior to his appointment as Chief Financial Officer. Mr. Muller has been responsible for leading the Company’s strategic direction related to digital infrastructure development and data center contracting. Prior to that, he led the Company’s PJM Fossil business unit, where he was responsible for the Company’s eight gigawatts of PJM generation assets. Before joining the Company in 2018, he was an Associate Partner for McKinsey & Co., advising energy clients, including the Company, on strategic opportunities and operational transformations. He also previously served as a submarine officer in the U.S. Navy.  A graduate of the U.S. Naval Academy, Mr. Muller holds a Bachelor of Science degree in Mathematics. He received his MBA from The Wharton School, and his JD from the University of Pennsylvania.

Employment Agreements and May 2026 Equity Award Settlement

In connection with these leadership changes. Messrs. McFarland, Nutt, Muller, Wright, Berryman, Morice Lebsack and Olagues all entered into new employment agreements that replace the existing agreements that were generally set to terminate in May 2026. These agreements contain an initial term through February 28, 2027 (subject to automatic annual renewals thereafter unless the executive or the Company provide 90 days’ written notice of their intent not to extend the term).

As part of the Company’s retention planning efforts, the employment agreements contain a provision that allows up to 60% of the performance stock units and time-based restricted stock units that were granted in connection with the Company’s emergence from restructuring (the “Emergence Awards”) to be settled in cash based on the Company’s share price at the time of vesting in May 2026 (the “Cash Settlement”). The impact of this provision is expected to have a significant anti-dilutive effect on the number of Talen shares issued and outstanding in the public market. In consideration for the Cash Settlement, each executive has agreed to a further lock-up of any shares of Talen common stock received in the settlement of the Emergence Awards through November 13, 2026.

For illustrative purposes, utilizing an assumed stock price of $400 per share on the vesting date and a 60% post-tax Cash Settlement for certain plan participants, Talen would settle all of the plan participants’ vested Emergence Awards in approximately $388 million in cash for withholding taxes, $369 million in Cash Settlement and approximately 680,000 shares of Talen stock (as compared to issuing approximately 2,573,000 shares of Talen stock (inclusive of withholding taxes) if the Emergence Awards were not partially cash settled).

The Cash Settlement is subject to the ability of the Compensation Committee of the Board (the “Committee”) to modify the portion of the Emergence Awards that is cash-settled if the Committee determines that cash settlement would materially and adversely affect the Company.

Following the expected Cash Settlement in May 2026, the following named executive officers of the Company are projected to retain a significant level of stock ownership in the Company as measured in the Company’s Stock Ownership Guidelines (“SOG”) in multiples of annual base salary (calculations assume a $400 share price on the vesting date and a 60% post-tax cash settlement of the Emergence Grant and reflects only the shares received by the applicable executive in his Emergence Grant):

                                        

In addition, as part of the Company’s retention efforts, the extended employment agreements provide that the Company will grant new time-based restricted stock units and performance stock units in February 2026 that will vest over a two and three-year period (i.e., vesting in 2028 and 2029). These grants will be made in addition to the Emergence Awards and the previously granted time-based restricted stock units and performance stock units that will vest in 2027.
