THIRD QUARTER 2013 RESULTS

For the third quarter ended September 30, 2013, the Company earned net income of $7.5 million, or $0.31 per basic and diluted share. Included in the net income was $37.5 million of net unrealized gain on MBS, $48.5 million of net realized loss on MBS (including other loss on mortgage-backed securities of $2.4 million), and $4.4 million of net loss on derivative instruments and linked transactions. During the period, the Company generated core earnings of $20.1 million, or $0.83 per basic and diluted share. Core earnings represents a non-GAAP financial measure and is defined as net income (loss) excluding: (i) net realized gain (loss) on investments and derivative contracts; (ii) net unrealized gain (loss) on investments; (iii) loss resulting from mark-to-market adjustments on derivative contracts; (iv) other loss on RMBS; (v) non-cash stock-based compensation expense; and (vi) one-time events pursuant to changes in GAAP and certain other non-cash charges, if any. Net interest income for the period was $26.4 million.

For the quarter ended September 30, 2013, the Company’s weighted average yield on its portfolio was 3.42%, including Agency and Non-Agency MBS, interest from Interest-Only securities accounted for as derivatives and linked transactions that occurred during the quarter. The Company’s effective cost of funds on its Agency and Non-Agency MBS financing (including the cost of interest rate swaps and linked transactions) was 1.14%. The annualized net interest spread on its portfolio was 2.28%, including Agency and Non-Agency MBS, interest from Interest-Only securities accounted for as derivatives and linked transactions, and taking into account the cost of the interest rate swaps. This compares with a weighted average yield of 3.14%, an effective cost of funds of 0.96%, and an annualized net interest spread of 2.18% for the quarter ended June 30, 2013.

CONSTANT PREPAYMENT RATES

The actual constant prepayment rate (“CPR”) for the Company’s Agency RMBS portfolio during the third quarter was 5.3% on an annualized basis, as compared to 4.4% for the second quarter of 2013.

“During the third quarter of 2013, we saw rather dramatic price swings in the Agency MBS market. In July and August, prices declined on concern that the Federal Reserve would begin tapering its purchases of Agency RMBS earlier than expected and then in mid-September, prices rose as investors reacted to the Federal Reserve’s announcement that it would not begin tapering its purchases,” said Gavin James, Chief Executive Officer of Western Asset Mortgage Capital Corporation. “We are pleased to have generated a positive economic return on book value of approximately 1.8% for the quarter.3 We believe that we are well positioned to generate continued positive results through the remainder of the year, based on the current interest rate environment and the subdued nature of the U.S. economic recovery.”

3 “Economic return” for any period is calculated as the change in book value over the period plus dividends paid.

Anup Agarwal, Chief Investment Officer of Western Asset Mortgage Capital Corporation, commented, “Since our initial public offering in May 2012 through September 30, 2013, WMC has delivered an economic return of 9.6%, despite challenging conditions for investing in mortgage-backed securities. We believe that our ability to achieve this result over that time frame is a testament to the breadth and depth of Western Asset’s entire MBS team. While our current portfolio is primarily focused on Agency RMBS, over the quarter we have continued to increase our holdings of Non-Agency RMBS and have also added for the first time a small amount of CMBS, as we believe that these securities offer attractive risk adjusted returns and can serve as a complement to our existing Agency RMBS holdings. Under current market conditions we expect to further expand our investments in these sectors while maintaining the core focus on Agency RMBS.”

There can be no assurance that the Company will attain any investment objective or result.

DIVIDEND

On September 19, 2013, the Company declared a regular dividend of $0.90 per share of common stock with respect to the quarter ended September 30, 2013. Since inception WMC has declared and paid total dividends of $106.6 million or $5.10 per share.
