The special committee reviewed multiple bids as part of a thorough process that involved multiple parties and evaluated the transaction against the Company's standalone prospects, performance and outlook relative to historic trading multiples and yields. Based on this review and in light of the transaction structure, the special committee unanimously determined that this transaction is in the best interest of the Company's shareholders and recommended it to the full Pattern Energy Board, which also determined that this transaction is advisable and in the best interests of the Company's shareholders. The transaction delivers significant, immediate and certain value to the Company's shareholders."
