Core's president, Mitesh Thakkar, is assuming an expanded role within the organization, with day-to-day responsibility for the company's primary operating functions, including operations, marketing, logistics, and long-term strategy, effective immediately.

"On behalf of the entire board, I want to congratulate Mitesh on this long-planned and well-deserved expansion of his responsibilities," said Jimmy Brock, Core's chairman and CEO. "The board views Mitesh as the ideal person to lead Core's day-to-day endeavors at this exciting time in the company's development and growth. Mitesh is a proven leader and strategic thinker with an exceptional track record across a range of critical functions, and I look forward to continuing to work closely with him to unlock Core's full potential."

As part of this transition, the board also announced the election of Nathan Tucker as Core's senior vice president and chief financial officer, effective immediately.

"Nate has distinguished himself as a strong and effective leader with exceptional financial acumen and a keen understanding of Core's business, and I am confident he will excel in this important role," said Brock.  

"Nate will do an excellent job leading Core's highly talented finance and accounting team," said Thakkar. "I look forward to working closely with him as we seek to drive exceptional future value for our stockholders."

Thakkar had served as Core's president and chief financial officer since the company's formation in January 2025. Prior to that time, he had held the position of senior vice president and chief financial officer of CONSOL Energy Inc. ("CONSOL") – one of Core's predecessor companies – since 2020. Thakkar joined CONSOL in 2015 after beginning his career as an equity analyst with FBR Capital Markets (now part of B. Riley FBR, Inc.).

Tucker had served as Core's vice president of finance since the company's formation. He had previously served as director of finance and investor relations for CONSOL from 2020 until January 2025 after joining CONSOL in 2010.
