ANNOUNCES SHARE REPURCHASE PROGRAM

Pasadena, CA, November 19, 2012 — Western Asset Mortgage Capital Corporation (NYSE: WMC) today announced that its Board of Directors has authorized the repurchase of up to 2.4 million shares of its common stock through December 31, 2013.  Purchases made pursuant to the program will be made in the open market, in privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rules 10b5-1 and 10b-18 of the Securities and Exchange Commission. The authorization does not obligate the Company to acquire any particular amount of common shares and the program may be suspended or discontinued at the Company’s discretion without prior notice. The timing, manner, price and amount of any repurchases will be determined by the Company in its discretion and will be subject to economic and market conditions, stock price, applicable legal requirements and other factors.

“This share repurchase authorization reflects the Company’s continued commitment to enhancing shareholder value,” said Gavin James, Chief Executive Officer of Western Asset Mortgage Capital Corporation. “We believe providing the opportunity to repurchase shares, especially when prices are materially below our estimated net book value, represents an attractive additional tool to generate value for our shareholders.”
