Atlantic Power Provides an Update on Convertible Debentureholder Meeting

DEDHAM, Mass., April 15, 2021 /PRNewswire/ -- Atlantic Power Corporation (NYSE: AT) (TSX: ATP) ("Atlantic Power" or the "Company") announced today that the parties to the previously announced proposed transaction among Atlantic Power, Atlantic Power Preferred Equity Ltd. ("APPEL"), Atlantic Power Limited Partnership ("APLP") and certain affiliates (collectively the "Purchasers") of infrastructure funds managed by I Squared Capital Advisors (US) LLC (the "Transaction") are continuing to work through the steps required to close the Transaction without the approval of holders of the Company's 6.00% Series E convertible unsecured subordinated debentures due January 31, 2025 (the "Convertible Debentures").

It is expected that these steps will still offer to the holders of Convertible Debentures the benefit of the "make whole premium" contemplated by the indenture governing the Convertible Debentures. Additional details will be provided once these steps are substantially finalized.

As previously announced, the parties intend to close the Transaction without the approval of the holders of the Convertible Debentures unless a sufficient number of Convertible Debentures are voted in favor of the Transaction as currently structured.

In the interim, the Company also announced that it is adjourning the meeting (the "Debentureholder Meeting") of holders of the Convertible Debentures currently scheduled to be held at 10:00 a.m. (Toronto time) on April 15, 2021 to consider the Transaction. The Debentureholder Meeting is being adjourned until 10:00 a.m. (Toronto time) on April 29, 2021. Holders of Convertible Debentures are urged to submit their proxies or voting instructions well in advance of the revised proxy cut-off time of 10:00 a.m. (Toronto time) on April 27, 2021. Unless a sufficient number of Convertible Debentures are voted in favor of the Transaction as currently structured, it is expected that the adjourned Debentureholder Meeting will be cancelled and the condition precedent to the Transaction that the holders of the Convertible Debentures approve the Transaction will be mutually waived.

The Transaction remains subject to the satisfaction or waiver of certain conditions, including court approval of the Transaction, approval of the holders of Convertible Debentures, certain remaining regulatory approvals and third-party consents and other customary closing conditions. As previously disclosed, the Transaction has already received approval from the holders of common shares of the Company, preferred shares of APPEL and medium term notes of APLP, and the Transaction has also received certain required regulatory approvals, including an advance ruling certificate from the Canadian Commissioner of Competition under the Competition Act (Canada) on February 5, 2021, the expiration of the required waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 on March 9, 2021, and the approval of the Federal Energy Regulatory Commission on April 2, 2021. The parties currently expect to close the Transaction in the second quarter of 2021.
