TerraForm Power Announces 20% Increase of Quarterly Dividend to $0.27 Per Share

BELTSVILLE, Md., Dec. 22, 2014 (GLOBE NEWSWIRE) -- TerraForm Power, Inc. (Nasdaq:TERP) today announced that its Board of Directors declared a quarterly dividend for the fourth quarter on the Company's Class A common stock of $0.27 per share, or $1.08 per share on an annualized basis. This reflects a 20% increase over the third-quarter dividend of $0.2257 per share, or $0.90 per share on an annualized basis. The fourth-quarter dividend is payable on March 16, 2015 to shareholders of record as of March 2, 2015.

TerraForm Power's third-quarter dividend was prorated to $0.1717 to adjust for a partial quarter (the Company closed its Initial Public Offering of shares on July 23, 2014.)

"The 20% increase in our fourth quarter dividend is a direct result of TerraForm Power's continued strong performance and execution against strategy, including the closings of the Capital Dynamics and Hudson Energy Solar acquisitions as well as accelerated drop downs from SunEdison," said Carlos Domenech, President and Chief Executive Officer of TerraForm Power. "With the recently announced acquisition of First Wind and significant project wins by SunEdison, we continue to be well positioned to expand our high quality portfolio and meet our dividend growth objectives for our shareholders."
