Pattern Energy Files Form 8-K Related to 2014 Second Quarter Filing

SAN FRANCISCO, CALIFORNIA, October 24, 2014 – Pattern Energy Group Inc. (NASDAQ: PEGI) (TSX: PEG) today announced that it intends to amend its Quarterly Report on Form 10-Q for the quarter ended June 30, 2014 to restate the calculation of earnings per share in its quarterly financial statements for the three and six months ended June 30, 2014, and has filed a current report on Form 8-K to this effect with the Securities and Exchange Commission.

The earnings per share calculation contained in the Quarterly Report on Form 10-Q filed on August 5, 2014 did not recognize a non-cash deemed dividend attributable to the Class B common stock. The deemed dividend represents non-cash accretion of a "beneficial conversion feature" on Class B common stock. The beneficial conversion feature represents the intrinsic value of the conversion feature, which is the difference between the fair values, measured as of the date of the Company's initial public offering, of the Class B common stock and the Class A common stock into which the Class B common stock is convertible. The value of the beneficial conversion feature is accreted on a straight-line basis from the commercial operations date of the Company's South Kent project (March 28, 2014) to the date the Class B common stock will convert into Class A common stock (December 31, 2014).

The holders of Class B common stock are not entitled to receive dividends at any time, and are not entitled to any other form of preferred return over the returns available to the holders of Class A common stock, and therefore, the deemed dividend does not represent a current or future distribution of Company earnings.
