CME Group announced senior leadership appointments in its finance and legal divisions, the company said in a filing.

Jack Tobin, who has served as CME Group Chief Accounting Officer since 2015, will be promoted to Chief Financial Officer effective March 2027, when current President & CFO Lynne Fitzpatrick becomes CEO as previously announced. To ensure a smooth transition, Tobin will become Deputy Chief Financial Officer in November 2026. He will continue to report to Fitzpatrick.

Matthew Render will succeed Tobin as Chief Accounting Officer and will continue to report to Tobin. Render joined CME Group as Deputy Chief Accounting Officer in August 2026 and previously held finance roles at Citadel, BP and Ernst & Young.

John Marchese has been promoted to General Counsel, joining the CME Group management team and reporting to Chairman and CEO Terry Duffy. Marchese has been Managing Director & Associate General Counsel, Litigation & Information Technology since 2024, and later this month will succeed Jonathan Marcus, who is stepping down after serving as General Counsel since 2022.

Duffy said the appointments demonstrate the bench strength CME Group has developed across its leadership team and thanked Marcus for his counsel to the company.

Tobin has more than 35 years of financial experience, including overseeing accounting, corporate development and finance functions at CME Group since joining the company in 2002. He previously worked as a principal consultant with PricewaterhouseCoopers and earned bachelor's and master's degrees from DePaul University.
