SAN FRANCISCO, CALIFORNIA – January 17, 2017 – Pattern Energy Group Inc. (the “Company” or “Pattern Energy”) (NASDAQ: PEGI) (TSX: PEG) today announced that it proposes to offer, subject to market conditions and other factors, US$350 million aggregate principal amount of senior notes due 2024 (the “Notes”) to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in accordance with Regulation S under the Securities Act (the “Offering”). The Notes will be guaranteed on a senior unsecured basis by Pattern US Finance Company LLC.

Specifically, the Company intends to use approximately US$215 million of the net proceeds from the Offering to partially fund its acquisition of the Broadview project, approximately US$128 million to repay borrowings under its revolving credit facility used to finance the purchase of the Armow project, of which US$125 million was drawn after September 30, 2016, and any remaining net proceeds to finance other green projects and to pay related fees, expenses and other costs related thereto.

The Notes are being offered only to qualified institutional buyers in reliance on Rule 144A under the Securities Act or to certain non-U.S. persons outside the United States in accordance with Regulation S under the Securities Act. The Notes have not been registered under the Securities Act and may not be offered or sold absent registration or an applicable exemption from the registration requirements of the Securities Act. In Canada, the Notes may be offered on a prospectus-exempt basis to certain accredited investors (as defined under applicable Canadian securities laws) who are also qualified institutional buyers.

This press release does not constitute an offer to sell or the solicitation of an offer to buy these securities, nor shall it constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale is unlawful.
