First Quarter 2014 Financial Highlights

First Quarter 2014 Other Highlights

“AMTG had another solid quarter of operating results, as the mortgage-backed securities markets showed signs of stability,” said Michael Commaroto, the Chief Executive Officer of the Company. “The Company’s book value per common share increased 2.1% in the first quarter, bolstered by strong underlying performance from both the Agency and non-Agency RMBS portfolio. In addition, during the quarter the Company began executing on a new credit strategy whereby AMTG entered into an agreement with a third party to fund the purchase of residential properties with a view towards selling the properties to homeowners and providing seller financing. As the Company scales this new business, we continue to explore additional residential mortgage credit strategies in our efforts to expand AMTG’s credit investment portfolio.”

Estimated Taxable Income

Estimated taxable income for the quarter ended March 31, 2014 was $0.44 per common share, or $0.09 lower than the Company’s operating earnings per common share. This difference primarily reflects estimated tax to GAAP timing differences associated with: (i) discount accretion on certain non-Agency RMBS and (ii) the amount of income the Company recognized in connection with its February 2013 securitization transaction. With respect to the timing difference arising from the Company’s non-Agency RMBS, bonds that are “locked-out” from receiving principal payments (until the more senior bonds in the securitization structure are repaid) generate significantly less income for tax purposes than under GAAP. This timing difference is expected to begin to reverse as the bonds that are currently locked-out begin receiving principal payments. With respect to timing differences arising from the securitization transaction, the securitization was treated as a sale for tax purposes and, effectively, treated as financing for GAAP purposes, whereby the Company consolidates the securitization trust under GAAP. As a result of these differences, for tax purposes no interest income is recognized on the Company’s securitized mortgage loans and no interest expense is recognized for the Company’s securitized debt; instead, interest income is recognized on the subordinated bonds received from the Company’s consolidated trust.

Book Value

The Company’s book value per common share at March 31, 2014 was $18.64 as compared to book value per common share of $18.26 at December 31, 2013.

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.

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. To present for investors 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.
