DYNEX CAPITAL, INC. ANNOUNCES $50.0 MILLION SHARE REPURCHASE PROGRAM

GLEN ALLEN, Va - Dynex Capital, Inc. (NYSE: DX) (“Dynex” or the “Company”) announced today that its Board of Directors has authorized the repurchase of up to $50.0 million of its outstanding shares of common stock through December 31, 2016. The Company will only repurchase shares when the repurchase price per share is less than the Company’s most recent estimate of the current net book value of a share of common stock.

As part of the share repurchase program, shares may be purchased in open market transactions, including through block purchases, through privately negotiated transactions, or pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934 (the “Exchange Act”). The timing, manner, price and amount of any repurchases will be determined in the Company’s discretion and the share repurchase program may be suspended, terminated or modified at any time for any reason. The repurchase program does not obligate the Company to acquire any specific number of shares, and all open market repurchases will be made in accordance with Exchange Act Rule 10b-18, which sets certain restrictions on the method, timing, price and volume of open market stock repurchases.

This new authorization replaces the Company’s prior share repurchase program, which was to expire on December 31, 2014.
