APOLLO RESIDENTIAL MORTGAGE, INC. REPORTS

SECOND QUARTER 2015 FINANCIAL RESULTS

New York, NY, August 5, 2015 - Apollo Residential Mortgage, Inc. (the “Company”) (NYSE: AMTG) today reported financial results for the quarter ended June 30, 2015.

“AMTG produced strong operating earnings during the second quarter amidst a backdrop of heightened volatility throughout the global fixed income markets,” said Michael Commaroto, Chief Executive Officer and President of the Company. “The increase in AMTG’s operating earnings per share of common stock primarily reflects the growth in the Company’s credit focused investments, coupled with the improvement in yield and decline in funding costs for non-Agency RMBS. While AMTG’s financial performance was strong, the Company’s book value was negatively impacted by interest rate movements and spread widening in the fixed income market. We continue to focus on optimizing the Company’s investment portfolio and expanding AMTG’s credit related investment initiatives.”

Estimated Taxable Income

The Company’s taxable income may vary significantly on a quarterly basis. Estimated taxable income for the quarter ended June 30, 2015 was $0.33 per share of common stock, or $0.23 lower than the Company’s operating earnings per share of common stock. This difference primarily reflects estimated tax to GAAP timing differences associated with discount accretion on certain non-Agency RMBS. These fluctuations primarily are attributable to changes in cash flows on the Company’s locked-out non-Agency RMBS, which impacts the timing of market discount accretion the Company recognizes for tax purposes on such securities. Certain locked-out bonds may move from being locked-out to current pay, and vice-versa, depending on the performance of the underlying collateral and the associated triggers specified in the securitization structure.

Book Value

The Company’s book value per share of common stock at June 30, 2015 was $18.31 as compared to book value per share of common stock of $19.21 at March 31, 2015.

Reconciliations of Non-GAAP Financial Measures

Included in this press release are disclosures about the Company’s “operating earnings,” “operating earnings per share of common stock,” “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 share of common stock 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 Manager to assess the Company’s business results.

While the Company has not elected hedge accounting under GAAP for its Swaps, such derivative instruments are viewed by the Company as an economic hedge against increases in future market interest rates. To present how the Company views its Swaps, the Company provides the “effective cost of funds” which is comprised of GAAP interest expense plus the interest expense component for Swaps. The interest expense component of the Company’s Swaps reflects the net interest payments made or accrued on its 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 believes 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 six month periods ended June 30, 2015 and the three and six month periods ended June 30, 2014, are presented in the tables below.
