APOLLO RESIDENTIAL MORTGAGE, INC. REPORTS

FOURTH QUARTER AND FULL YEAR 2013 FINANCIAL RESULTS

New York, NY, February 19, 2014 - Apollo Residential Mortgage, Inc. (the “Company”) (NYSE: AMTG) today reported financial results for the quarter and full year ended December 31, 2013.

Fourth Quarter 2013 Financial Highlights

Full Year 2013 Financial Highlights

Other Highlights at December 31, 2013

“AMTG had a solid year of operating results against the backdrop of a challenging fixed income market,” said Michael Commaroto, Chief Executive Officer of the Company. “The Company’s portfolio continues to have a strong focus on non-Agency RMBS, a market that performed well in 2013, fueled by the ongoing positive trends in housing. In addition, the Company’s operating results benefitted in the fourth quarter from slower prepayments in the Agency RMBS portfolio as well as some Agency RMBS portfolio rebalancing. As we navigate through the current landscape in the mortgage market, we believe AMTG’s portfolio equity, which was allocated 47% to non- Agency RMBS and securitized mortgage loans, 44% to Agency RMBS and 9% to cash at December 31, 2013, is well positioned.”

Reconciliations of Non-GAAP Financial Measures

Included in this press release are disclosures about the Company’s “operating earnings,” “operating earnings per common share,” “effective cost of funds,” “effective interest expense,” “effective levered asset yield” and “effective net interest rate spread” which measures constitute non-GAAP financial measures within the meaning of Regulation G promulgated by the Securities and Exchange Commission. The Company believes that the non-GAAP financial measures presented, when considered together with GAAP financial measures, provide information that is useful to investors in understanding the Company’s operating results. An analysis of any non-GAAP financial measures should be made in conjunction with results presented in accordance with GAAP.

Operating earnings and operating earnings per common share presented exclude, as applicable: (i) certain realized and unrealized gains and losses recognized through earnings; (ii) non-cash equity compensation; (iii) one time events pursuant to changes in GAAP; and (iv) certain other non-cash charges. Operating earnings is a non-GAAP financial measure that is used by the Company to assess its business results.

To determine the effective cost of funds, interest expense is adjusted to include the net interest component related to Swaps. While the Company has not elected hedge accounting for its Swaps, such derivative instruments are viewed by the Company as an economic hedge against increases in future market interest rates. Therefore, the Company presents the effective cost of funds to reflect interest expense as adjusted to include a portion of the realized loss (i.e., the interest expense component) for Swaps.

The Company believes that the presentation of effective cost of funds is useful for investors as it presents the Company’s borrowing costs as viewed by management. The Company believes that the non-GAAP measures presented provide investors, and other readers of this press release with meaningful information to assess the performance of the Company’s ongoing business and believe it is useful supplemental information for both management and investors in evaluating the Company’s financial results. The primary limitation associated with operating earnings as a measure of the Company’s financial performance over any period is that such measure excludes, except for the net interest component of Swaps, the effects of net realized and unrealized gains and losses from investments and realized and unrealized gains and losses from derivative instruments. In addition, the Company’s presentation of operating earnings may not be comparable to similarly-titled measures of other companies, who may use different definitions or calculations for such term. As a result, operating earnings should not be considered as a substitute for GAAP net income as a measure of the Company’s financial performance or the Company’s liquidity under GAAP.

A reconciliation of the GAAP items discussed above to their non-GAAP measures for the three and twelve months ended December 31, 2013 and the three and twelve months ended December 31, 2012, are presented in the tables below.
