Bitcoin Miner Argo Blockchain Loses CEO

Peter Wall, the CEO and interim chairman of bitcoin mining firm Argo Blockchain (ARBK), has resigned after three years, the company said in a Thursday press release.

The London-based company had a difficult 2022 as soaring power prices raised operating costs at Helios, its biggest site, where the miner didn't have a fixed-rate power agreement. After trying to raise funds to stave off bankruptcy, Argo sold the Texas facility to Galaxy Digital for $65 million.

Seif El-Bakly will act as interim CEO and Matthew Shaw has been appointed chairman of the board, according to the company's website. CFO Alex Appleton announced his resignation last week.

The company's London-traded shares (ARB) fell more than 10% to 16.6 pence (20 U.S. cents) as of 08:38 UTC.

UPDATE (Feb. 9, 08:46 UTC): Rewrites headline; Adds tenure in first paragraph, share price in last.
