Lake Oswego, Oregon, July 15, 2013 – The Greenbrier Companies, Inc. (NYSE:GBX) reported that affiliates of WL Ross & Co. LLC (“WL Ross”) have exercised all their remaining warrants in Greenbrier resulting in 862,400 shares of common stock being issued in a cashless net exercise. WL Ross subsequently sold 431,200 shares of the newly issued Greenbrier common stock and continues to own the remaining 431,200 shares. The warrants were issued to affiliates of WL Ross in 2009 in connection with an investment in Greenbrier, and were due to expire in June 2014.

Wendy Teramoto, a partner with WL Ross, continues to serve on Greenbrier’s board of directors. Additionally, Greenbrier provides management services on nearly 4,000 railcars acquired in 2010 by WLR-Greenbrier Rail, Inc., an affiliate of WL Ross.

“Our timeline for exercising the warrants, which expire in June 2014, and subsequent sale of a portion of our holdings, is consistent with the original investment goals set with Greenbrier at the outset of our investment. We are pleased with the success of our investment and the success of Greenbrier,” said Wilbur L. Ross, Jr., chairman of WL Ross. “The current sale of shares was made to provide our limited partners liquidity and flexibility and represents an orderly redistribution of our assets. We have great confidence in Greenbrier’s prospects, as demonstrated by our ongoing business partnerships with them and our continuing investment in shares of Greenbrier common stock.”

“We appreciate WL Ross’ confidence in Greenbrier, as evidenced by their continued shareholdings and Board position. This is a vote of confidence in our strategy to create shareholder value through improved cash flows, margins, and stock valuation,” said William A. Furman, president and chief executive officer of Greenbrier. “WL Ross helped us stabilize our balance sheet during the banking crisis and fueled our present growth with a timely infusion of capital. Beyond that, the firm brings valuable insight and wisdom to Greenbrier through access to one of the most savvy and successful investors in America. We are delighted that Wendy continues to serve on our board and plan to pursue gainful business collaborations with WL Ross well into the future.”
