Atlantica Sustainable Infrastructure (AY) 6-KClosing of Atlantica’s Acquisition by Energy Capital Partners and Co-Investors Expected December 12

Closing of Atlantica’s Acquisition by Energy Capital Partners and Co-Investors Expected December 12

November 4, 2024 – Atlantica Sustainable Infrastructure plc (NASDAQ: AY) (“Atlantica” or the “Company”), announced today that the pending acquisition of the Company by Energy Capital Partners and a group of co-investors (the “Transaction”) is expected to close on December 12, 2024.

All regulatory approvals required in connection with Transaction (including clearance by the Committee on Foreign Investment in the United States and by the Federal Energy Regulatory Commission in the United States) were received by October 25th.  Due to the limited availability of court dates and the mutual desire of the parties to effect an orderly closing of the Transaction, the parties have agreed a date for the hearing of the High Court of Justice of England and Wales (the “Court”) to sanction the Transaction on December 10, 2024.  Closing will therefore take place two business days later, on December 12, 2024.

In connection with the scheduling of the closing, Atlantica and Energy Capital Partners have agreed that Atlantica may declare and pay a final cash dividend of up to $0.2225 per Atlantica share on or prior to the closing.  The declaration and payment of that dividend is subject to the approval and authorization of the Atlantica board of directors at an upcoming scheduled board meeting.  If approved, details of such dividend, including the relevant record date, are expected to be confirmed in a further release to be made by the Company in relation to its third quarter 2024 results, expected to be published on November 14, 2024 after market close.

For further information regarding the Transaction and the relevant agreements related thereto, please see the Report of Foreign Private Issuer on Form 6-K filed on May 28, 2024 by the Company, including the exhibits thereto and the Report of Foreign Private Issuer on Form 6-K filed on July 16, 2024, including the exhibits thereto. The descriptions of the Transaction and such agreements outlined above do not purport to be complete and are qualified in their entirety by reference to the full text of such agreements which are exhibits to the abovementioned Reports of Foreign Private Issuer on Form 6-K.
