Ether Machine and Dynamix mutually scrap SPAC merger, blame 'unfavorable market conditions'

The Ether Machine's path to the public markets via Dynamix Corporation is over. In a statement posted Friday night, the would-be ether treasury company said it had "mutually agreed to terminate" its previously announced Business Combination Agreement with the Nasdaq-listed SPAC, "effective immediately, as a result of unfavorable market conditions."

The deal, originally announced on July 21, 2025, would have taken The Ether Reserve LLC public through a combination with Dynamix, with the surviving entity trading under the ticker ETHM. At the time, the firm said it expected to launch with more than 400,000 ETH on its balance sheet, a sum now worth about $900 million, thanks largely to a 170,000 ETH contribution from co-founder and early Consensys member Andrew Keys. 

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

The breakup is not without a consolation prize for Dynamix. A "Payor" identified on Annex A of the agreement, likely connected to The Ether Machine, is contractually obligated to wire $50 million to the SPAC within 15 days of the April 8 effective date. The parties also exchanged broad mutual releases, non-disparagement covenants, and indemnification arrangements covering investor-related litigation risk.

The $50 million figure is significant relative to Dynamix's roughly $232 million market capitalization. It is unclear from the filing whether the Payor is The Ether Reserve, its affiliates, or another backer of the original transaction, but presuming the fee is a breakup fee, the Payor is likely connected to the entity. 

Dynamix is not yet out of options. The Cayman Islands-domiciled SPAC retains its November 22, 2026 deadline to consummate an initial business combination. If it fails to 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.

The collapse comes amid a broader cooling in digital asset treasury (DAT) vehicles and crypto-adjacent SPAC listings, as ether's price has struggled to sustain momentum in recent months. The Ether Machine had been pitched as a vehicle to accumulate and stake ETH at scale on behalf of public-market investors.

Currently, 10 Ethereum treasury companies are active, holding more than 6 million ETH worth nearly $14 billion, according to The Block's Ethereum Treasury Tracker. The largest, Tom Lee's Bitmine, recently uplisted its stock to the New York Stock Exchange while 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.
