The Ethereum treasury company The Ether Machine and Dynamix’s $1.6 billion SPAC merger has been officially terminated.

According to CoinDesk, The Ether Machine, an Ethereum treasury company, and special purpose acquisition company (SPAC) Dynamix Corporation (ticker: DYNX), announced on Friday that they have agreed to terminate their previously planned $1.6 billion merger deal due to unfavorable market conditions. Per filings submitted to the U.S. Securities and Exchange Commission (SEC), The Ether Machine must pay Dynamix a $50 million termination fee within 15 days. The merger agreement was first disclosed in July 2025 and originally aimed to list The Ether Machine on the Nasdaq under the ticker ETHM. In terms of transaction size, the agreement included a fully committed $1.5 billion PIPE financing (reportedly the largest all-common-stock PIPE financing of its kind since 2021), along with approximately $170 million held in Dynamix’s trust account. Following the merger, the combined company was expected to hold over 400,000 ETH on its balance sheet. The Ether Machine positions itself as an Ethereum treasury and yield-generation vehicle, generating returns through staking and DeFi strategies while maintaining a large Ethereum reserve. According to CoinGecko data, the company currently holds 496,712 ETH, valued at over $1.1 billion.
