NEW YORK, Oct. 06, 2025 (GLOBE NEWSWIRE) -- Cipher Mining Inc. (NASDAQ: CIFR) ("Cipher" or the "Company"), a leading developer and operator of industrial-scale data centers, today announced a transition in its Chief Financial Officer ("CFO") role. Ed Farrell will become a Senior Advisor to the Company and Greg Mumford has been appointed incoming CFO. Both appointments will take effect upon Mr. Farrell's retirement on October 14, 2025.
Mr. Farrell was the Company's first CFO and was instrumental in the Company's tremendous success in its first five years. He played a pivotal role in taking the Company public in 2021 and provided strong financial leadership in successfully navigating Cipher through the challenges and opportunities of its early years as a publicly traded company. He will continue to share his expertise, insights, and extensive experience with Cipher in his new role as Senior Advisor. In this capacity, he will support the CFO leadership transition and continue to provide strategic guidance to the Company.
"I want to extend my deepest gratitude to Ed for his exceptional leadership in building Cipher's solid foundation and guiding our growth with unmatched financial expertise. He has assembled an outstanding finance team that leaves us well-positioned for this transition and the opportunities ahead," said Tyler Page, Cipher's CEO. "I am grateful for his partnership, collaboration, and friendship, and I look forward to benefitting from his continued counsel in the future. We will miss him and extend our best wishes to him and his family in his retirement."
Mr. Mumford will succeed Mr. Farrell and become Cipher's second CFO. Mr. Mumford brings more than a decade of experience across financial services, credit, and capital markets. Most recently, he was a senior banker in the Digital Assets & Infrastructure Investment Banking group at Keefe, Bruyette & Woods, where he advised on a wide range of M&A and capital markets transactions, with a focus on digital infrastructure and industrials. At Cipher, he will leverage his deep corporate finance expertise, spanning strategic advisory, structuring, and capital markets execution, to support the company's growth and long-term strategy. Mr. Mumford will lead the Company's finance department and serve on the Company's Executive Management Team. He will report to Mr. Page.
"We are thrilled to welcome Greg to the Cipher team at such an exciting time for the Company. His track record as a dealmaker, structuring complex transactions and navigating dynamic capital markets, makes him uniquely well-suited to help us capitalize on the extraordinary momentum and opportunities we are seeing in the HPC space," said Mr. Page. "His experience advising on transformative deals in digital infrastructure and industrials will be invaluable as we continue to scale."
