Item 1.01 – Entry into a Material Definitive Agreement.

On September 27, 2026, Drub LLC (“Buyer”), a Delaware limited liability company and an indirect subsidiary of FTAI Infrastructure Inc. (the “Company”), entered into a Membership Interest Purchase Agreement (the “Agreement”) with DRUbit Holdings LLC, a Delaware limited liability company (“Seller”), DRUbit LLC, a Delaware limited liability company (“DRUbit”), US Development Group LLC, a Delaware limited liability company (“USDG”), and, solely for limited purposes set forth therein, FTAI Energy Partners LLC, a Delaware limited liability company (“Buyer Parent”), pursuant to which, among other things, Buyer will purchase all of the issued and outstanding membership interests of DRUbit (the “Interests”) from Seller for a purchase price based on an enterprise value of $255 million, subject to certain customary adjustments for cash, indebtedness, net working capital and transaction expenses as set forth in the Agreement (the “Transaction”). Capitalized terms used and not otherwise defined herein have the meaning set forth in the Agreement, which is filed as Exhibit 10.1 hereto.

The Agreement contains customary representations, warranties, and covenants by the parties, including, among others, covenants: (1) by Seller regarding the conduct of DRUbit’s business during the period between the execution of the Agreement and closing of the Transaction; (2) by Buyer and Seller to obtain the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”); (3) by Buyer to obtain, and by Seller and DRUbit to cooperate in, the financing contemplated by the Agreement as discussed in more detail below; and (4) by Buyer and Seller regarding the efforts of the parties to cause the Transaction to be completed. In connection with its entry into the Agreement, Buyer has obtained and conditionally bound a buyer-side representations and warranty insurance policy (the “R&W Insurance Policy”) to cover certain losses arising out of a breach of the representations and warranties of Seller contained in the Agreement. The R&W Insurance Policy is subject to certain policy limits, exclusions, deductibles and other terms and conditions.

The consummation of the Transaction is subject to certain customary closing conditions, including, among others: (1) the absence of any law or order enjoining, restraining, preventing or otherwise prohibiting the consummation of the Transaction; (2) the expiration or termination of the applicable waiting period under the HSR Act; (3) the accuracy of each party’s representations and warranties contained in the Agreement (subject to certain materiality qualifiers); (4) each party’s performance and compliance in all material respects with their respective covenants and agreements under the Agreement; (5) the absence of a Material Adverse Effect (as defined in the Agreement); and (6) the absence of default under the indebtedness of DRUbit that is being assumed as part of the transactions.

The Agreement is terminable at any time prior to closing by mutual written consent of the parties and in the following circumstances: (1) by either party if the closing has not occurred by the date that is five months after the execution date; (2) by either party if any governmental authority has enacted any law or order which has become final and non-appealable that enjoins or prohibits consummation of the Transaction; (3) by either party if the other party is in material breach of a representation, warranty or covenant that results in the failure of a closing condition, subject to customary conditions and cure rights; (4) by either party in the event of certain significant casualty events; and (5) by Seller if all closing conditions have been satisfied and Buyer fails to consummate the closing following delivery of notice and a three business day cure period.

Under the Agreement, it is currently contemplated that DRUbit’s existing term debt (the “Assumed Debt”) will remain outstanding following closing, unless Buyer requests for it to be repaid in full prior to the closing, and the purchase price will be reduced by the outstanding amount owed under the Assumed Debt as of the closing. The Assumed Debt had a current principal balance of approximately $190 million as of September 27, 2026.  In connection with its entry into the Agreement, Buyer entered into a debt commitment letter, dated as of September 27, 2026, with Barclays Bank PLC, which provides for a commitment by Barclays Bank PLC, subject to conditions customary for transactions of this type, to provide a loan of $72 million to fund the remaining portion of the purchase price to be paid by Buyer.

Upon termination of the Agreement under specified circumstances where Buyer is in breach of its obligations (including termination by Seller in the event of Buyer’s breach or failure to close), Buyer would be required to pay Seller a termination fee of $15,300,000.  Concurrently with the execution of the Agreement, Buyer Parent delivered to Seller a limited guarantee in favor of Seller guaranteeing, on the terms and subject to the conditions set forth therein, the payment of Buyer’s obligation to pay a termination fee if and when payable pursuant to the Agreement.

On September 28, 2026, the Company issued a press release announcing the Transaction. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

In accordance with General Instruction B.2 of Form 8-K, the information contained in this Item 7.01 is being furnished under Item 7.01 of this Form 8-K 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 the liabilities of that section, nor shall such information and exhibits be incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
