Ether Machine and Dynamix terminate SPAC merger citing unfavorable market conditions

Dynamix Corporation and The Ether Machine said Friday they have mutually terminated their planned business combination, citing unfavorable market conditions. The termination, effective April 8, unwinds the previously announced path for The Ether Machine to reach the public markets through the Nasdaq-listed SPAC.

Termination details and payments

In a statement posted Friday night, The Ether Machine said the Business Combination Agreement with Dynamix was terminated “effective immediately” due to unfavorable market conditions.

Under the Termination Agreement, an unnamed “Payor” identified in the agreement’s Annex A is contractually obligated to pay Dynamix $50 million within 15 days of the April 8 effective date.

According to an SEC 8-K filed by Dynamix, the termination also unwinds related arrangements, including the Sponsor Support Agreement, ETHM Subscription Agreements, and the Contribution Agreement.

Background on the planned deal

The deal was originally announced on July 21, 2025. It would have taken The Ether Reserve LLC public through a combination with Dynamix, with the surviving entity expected to trade under the ticker ETHM.

At the time of announcement, The Ether Machine said it expected to launch with more than 400,000 ETH on its balance sheet. The article notes that the sum was then worth about $900 million, largely reflecting a 170,000 ETH contribution from co-founder and early Consensys member Andrew Keys.

Financial context for Dynamix

The $50 million payment is significant relative to Dynamix’s roughly $232 million market capitalization. The filing does not clarify whether the Payor is The Ether Reserve, its affiliates, or another backer of the original transaction, though the article characterizes the payment as a likely breakup fee.

What happens next for the SPAC

Dynamix remains a SPAC and has until November 22, 2026 to consummate an initial business combination. If it does not identify and close a new target by that date, its charter requires it to wind up, redeem public shares from the trust account in cash, and liquidate.

Broader market backdrop

The termination comes as digital asset treasury (DAT) vehicles and crypto-adjacent SPAC listings have cooled. The article attributes part of the pressure to ether’s price struggling to sustain momentum in recent months.

It also cites The Block’s Ethereum Treasury Tracker, which says 10 Ethereum treasury companies are active, holding more than 6 million ETH worth nearly $14 billion. The largest, Tom Lee’s Bitmine, recently uplisted its stock to the New York Stock Exchange and its board unanimously approved an increase to its 2025 share repurchase authorization from $1 billion to $4 billion.

Representatives for The Ether Machine and Dynamix did not immediately respond to requests for comment.
