The closing of the Company Unit Subscription occurred on September 8, 2025.

The information in this Item 7.01 is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of SPAC under the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act, regardless of any general incorporation language in such filings. This Current Report on Form 8-K will not be deemed an admission as to the materiality of any of the information in this Item 7.01.

Additional Information and Where to Find It

SPAC and Pubco intend to file with the Securities and Exchange Commission (the “SEC”) a Registration Statement on Form S-4 (the “Registration Statement”), which will include a preliminary proxy statement of SPAC and a prospectus of Pubco (the “Proxy Statement/Prospectus”) in connection with a proposed business combination (the “Business Combination”) and the other transactions contemplated by the Business Combination Agreement and/or described in this Current Report on Form 8-K (together with the Business Combination and the private placement investments, the “Proposed Transactions”). The definitive proxy statement and other relevant documents will be mailed to shareholders of SPAC as of a record date to be established for voting on the Business Combination and other matters as described in the Proxy Statement/Prospectus. SPAC and/or Pubco will also file other documents regarding the Proposed Transactions with the SEC. This Current Report on Form 8-K does not contain all of the information that should be considered concerning the Proposed Transactions and is not intended to form the basis of any investment decision or any other decision in respect of the Proposed Transactions.

Investors and security holders will also be able to obtain copies of the Registration Statement and the Proxy Statement/Prospectus and all other documents filed or that will be filed with the SEC by SPAC and Pubco, without charge, once available, on the SEC’s website at www.sec.gov or by directing a request to: Dynamix Corp, 1980 Post Oak Blvd., Suite 100, PMB 6373, Houston, TX 77056; e-mail: [email protected], or to: The Ether Machine, Inc., 2093 Philadelphia Pike #2640, Claymont, DE 19703, e-mail: [email protected].

ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.
