Subsequent events On January 14, 2021, Atlantic Power announced that it has entered into a definitive agreement with I Squared Capital, a leading global infrastructure investor, under which the company'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 total enterprise value of the deal is approximately $961 million and the Transaction was unanimously approved by Atlantic Power's board of directors. The Transaction is subject to a number of closing conditions, including court approval, regulatory approvals, as well as the receipt of certain third-party consents. A termination fee of $12.5 million will be payable by Atlantic Power to the Purchasers should the Transaction not close under certain circumstances, including if the Arrangement is not completed as a result of Atlantic Power accepting an unsolicited superior proposal. A reverse termination fee of $15 million will be payable by the Purchasers to Atlantic Power should the Transaction not close as a result of an uncured breach by the Purchasers of the Arrangement Agreement (provided Atlantic Power is not then in breach of the Arrangement Agreement). Following closing of the Transaction, the common shares of Atlantic Power will be delisted from the TSX and the NYSE and the preferred shares and convertible debentures will be delisted from the TSX. The parties currently expect to close the Transaction in the second quarter of 2021.
