COMMENTARY ON QUARTER

“In a challenging and volatile market, we continued to deliver strong performance by maintaining our focus on shareholder total return,” said Gavin James, Chief Executive Officer of Western Asset Mortgage Capital Corporation. “For the third quarter, we generated $0.67 of core plus drop income while maintaining our book value, providing our shareholders with a total return on book value of 4.2% for the quarter and 13.3% for the nine months through September 30, 2014.”

Anup Agarwal, Chief Investment Officer of Western Asset Mortgage Capital Corporation, commented, “Throughout the quarter and the year, we have maintained our position that the 10-year U.S Treasury would continue to trade in a range.  Accordingly, when yields approached the low end of our range, we decreased our Agency portfolio duration by adjusting our interest rate hedges.  While this increased our effective cost of funds for the quarter, it enabled us to maintain our book value and generate a positive total return for our shareholders. Additionally, over the course of the year, we have continued to expand our credit portfolio, increasing our holdings of Non-Agency RMBS, U.S. and European CMBS,  as well as ABS. We have completed the infrastructure to begin to invest in residential whole loans and in October completed our first investment in this asset class.  We currently find this an attractive investment opportunity and, subject to market conditions, intend to increase our exposure, over time.”

“We continue to have access to repo financing in excess of our current needs and are comfortable with our leverage, given our near-term outlook.  We will remain proactive in seeking to capture the relative value opportunities we have across the mortgage sector, as well as the broader fixed income and credit markets of eligible investments,” added Mr. Agarwal.

THIRD QUARTER 2014 RESULTS

For the third quarter ended September 30, 2014, the Company recorded GAAP net income of $26.1 million, or $0.63 per basic and diluted share. This compares to net income of $67.6 million, or $1.68 per basic and diluted share for the second quarter ended June 30, 2014. During the third quarter of 2014, the Company generated core earnings plus drop income of $27.8 million, or $0.67 per basic and diluted share. This compares to core earnings plus drop income of $40.0 million, or $1.00 per basic and diluted share for the second quarter ended June 30, 2014. 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 MBS and other securities; (v) non-cash stock-based compensation expense; and (vi) certain other non-cash charges. Drop income represents a non-GAAP financial measure and is derived from the use of ‘to-be-announced’ forward contract (“TBA”) dollar roll transactions and is defined as the difference between the spot price and the forward settlement price for a comparable security on the trade date.

3   September 30, 2014 book value per share reflects the $0.70 per share dividend declared on September 23, 2014 and paid on October 28, 2014.

4  Economic return is calculated by taking the sum of (i) the total dividends declared and (ii) the change in book value during the period and dividing by the beginning book value.

5  6.1x leverage calculation does not reflect net To-Be Announced (“TBA”) mortgage pass-through certificates position. As of September 30, 2014, the net long position in TBAs was $1,115 million in notional value.

For the quarter ended September 30, 2014, the Company’s weighted average yield on its portfolio was 3.75%, including Agency and Non-Agency MBS and other securities, interest from Interest-Only securities accounted for as derivatives and linked transactions that occurred during the quarter.
