DEDHAM, Mass., March 16, 2021 /PRNewswire/ -- Atlantic Power Corporation (NYSE: AT) (TSX: ATP) ("Atlantic Power") and its indirect, wholly-owned subsidiary, Atlantic Power Limited Partnership ("APLP") today announced the successful completion of APLP's previously announced consent solicitation process (the "Consent Solicitation") with respect to certain proposed amendments (the "Proposed Amendments") to the trust indenture (the "Note Indenture") governing the 5.95% Medium Term Notes due June 23, 2036 (the "Notes") of APLP.

As reported by the tabulation agent for the Consent Solicitation, holders of approximately 90% of the aggregate principal amount of Notes outstanding have delivered valid consents to the Proposed Amendments, exceeding the required consent threshold of two-thirds (66⅔%) of the principal amount of the Notes outstanding.

The Consent Solicitation was commenced in connection with the previously announced arrangement agreement (the "Arrangement Agreement") among Atlantic Power, APLP, Atlantic Power Preferred Equity Ltd. ("APPEL"), and Tidal Power Holdings Limited and Tidal Power Aggregator, L.P, each an affiliate of infrastructure funds managed by I Squared Capital Advisors (US) LLC, pursuant to which Atlantic Power's outstanding common shares and convertible debentures, and the outstanding preferred shares and medium term notes of certain of its subsidiaries, will be acquired (the "Transaction").

The Proposed Amendments, which are more fully described in the consent solicitation statement dated February 24, 2021 (the "MTN Solicitation Statement"), will among other things, result in an amendment to the Note Indenture to include a mandatory redemption obligation on the part of APLP, conditional on closing of the Transaction, to redeem all of the outstanding Notes for consideration equal to 106.071% of the principal amount of Notes outstanding, plus the payment of accrued and unpaid interest thereon up to, but excluding, the closing date of the Transaction.

APLP intends to execute a supplemental indenture, as close as reasonably practicable prior to the closing date of the Transaction, in order to give effect to the Proposed Amendments. Thereafter, all holders of Notes will be bound by the Proposed Amendments, including holders that did not give their consent.

Subject to the terms and conditions set forth in the MTN Solicitation Statement, and conditional on the closing of the Transaction, APLP will pay holders who validly consented to the Proposed Amendments on or prior to 5:00 p.m. (Toronto time) on March 16, 2021 a consent fee equal to 0.25% of the principal amount of Notes held by such holders and in respect of which a consent was validly delivered.

Atlantic Power also announced today that the meeting (the "Debentureholder Meeting") of holders ("Debentureholders") of its 6.00% Series E convertible unsecured subordinated debentures due January 31, 2025 initially scheduled to be held on March 18, 2021 at 10:00 a.m. (Toronto time) is being adjourned to Wednesday, April 7, 2021 at 12:00 p.m. (Toronto time) to allow additional time to solicit proxies.  

At the adjourned Debentureholder Meeting, Debentureholders will be asked to consider and, if deemed advisable, to pass an extraordinary resolution ("Extraordinary Resolution") authorizing certain amendments to the trust indenture governing the convertible debentures to provide for a mandatory conversion of the convertible debentures immediately prior to closing of the Transaction based on the conversion ratio in effect at such time (including the "make whole premium shares" issuable under the terms of the trust indenture governing the convertible debentures following a cash change of control). Debentureholders will receive US$3.03 per common share held following such conversion (including the "make whole premium shares"), plus accrued and unpaid interest on the convertible debentures up to, but excluding, the closing date of the Transaction. Additional information regarding the Debentureholder Meeting can be found in the management information circular mailed in connection with the Debentureholder Meeting, a copy of which is available on SEDAR at www.sedar.com and on Atlantic Power's website.

The Extraordinary Resolution requires approval by two-thirds of the principal amount of the convertible debentures voted in person or by proxy at the Debentureholder Meeting.

Only Debentureholders as of the record date for the Debentureholder Meeting (being the close of business on January 20, 2021) are entitled to and are being requested to vote on the Extraordinary Resolution. If a Debentureholder has previously submitted its proxy and does not wish to change its vote, no further action is required by such Debentureholder. Debentureholders are urged to submit their proxies or voting instructions well in advance of the revised proxy cut-off time of 12:00 p.m. (Toronto time) on April 5, 2021.

The Transaction remains subject to a number of closing conditions, including the approval of the following groups of securityholders:

• the approval of two-thirds of the votes cast by holders of Atlantic Power's common shares voting in person or by proxy at the special meeting of common shareholders of Atlantic Power to be held at 10:00 a.m. (Toronto time) on Wednesday, April 7, 2021 (the "Common Shareholder Meeting");
  
  
• the approval of two-thirds of the votes cast (in respect of both the Transaction and the proposed continuance of APPEL under the laws of British Columbia) by holders of APPEL's preferred shares voting in person or by proxy at the special meeting of preferred shareholders of APPEL to be held at 11:00 a.m. (Toronto time) on Wednesday, April 7, 2021 (the "Preferred Shareholder Meeting"); and
  
  
• the approval of two-thirds of the votes cast by Debentureholders at the adjourned Debentureholder Meeting.
