(Reuters) -Crypto miner Core Scientific ( CORZ ) on Thursday ended a deal for its sale to CoreWeave ( CRWV ) after shareholders voted against the proposal, marking the culmination of months-long investor and proxy campaigns against the agreement.

The move marks the second foiled attempt by CoreWeave ( CRWV ) to scoop up Core Scientific ( CORZ ), with the crypto miner also rejecting a June 2024 all-cash buyout offer.

CoreWeave ( CRWV ) had struck an all-stock deal worth $9 billion to buy Core Scientific ( CORZ ) in July, as part of its push to secure the energy and data center capacity needed to power surging demand.

Soon after, Two Seas Capital, which claims to be the largest active shareholder of Core Scientific ( CORZ ), said it would vote against the deal, citing concerns with the sale process, deal structure, and valuation.

It said the fixed exchange ratio left Core Scientific ( CORZ ) shareholders vulnerable to fluctuations in the price of CoreWeave ( CRWV ) shares.

Core's board had urged its shareholders to vote for the sale saying the combined company would benefit from several potential cost savings and synergies.

Last week, proxy advisory firm Institutional Shareholder Services also recommended investors vote against the deal, suggesting Core Scientific ( CORZ ) should continue going alone given its considerable success as a standalone company.

"We respect the views of Core Scientific ( CORZ ) stockholders and look forward to continuing our commercial partnership," said Michael Intrator, CoreWeave's ( CRWV ) CEO and co-founder.

Core Scientific ( CORZ ) shares fell 3.4% in early trading, while CoreWeave ( CRWV ) was down nearly 5%.
