Two Seas Capital, the largest shareholder of Core Scientific, has announced its intention to vote against the company's proposed $9 billion all-stock sale to CoreWeave. The investor criticized the deal for materially undervaluing Core Scientific, a bitcoin mining firm, and described the terms as too risky. This opposition raises the prospect of a proxy fight over the transaction. Separately, activist investor Engine Capital has built a stake in Avantor and plans to push the company to consider selling itself or making strategic changes. In related industry news, Vulcan Elements, a North Carolina-based startup specializing in rare-earth magnets, raised $65 million in a funding round led by Altimeter Capital, valuing the company at approximately $250 million. The funding will support Vulcan Elements' efforts to build a large-scale U.S. production facility aimed at reducing dependence on China for rare-earth magnets.
