$0.51 of Core Earnings per diluted common share⁽¹⁾

Legacy RMBS securities continue to benefit from a combination of strong demand and stable fundamentals, driving credit spreads to tighter levels

$0.23 or 1.2% due to our investments in Agency RMBS and associated derivative hedges

Spread tightening within the sector is well supported by solid fundamentals and increased demand, as market comfort with the Federal Reserve balance sheet plan grows

$(0.08) or (0.4%) primarily due to the declaration of a $0.10 special cash dividend

*The combined dividend of $0.575 includes a dividend of $0.475 per common share and a special cash dividend of $0.10 per common share

MANAGEMENT REMARKS

Commenting on TJ’s appointment, Chief Executive Officer David Roberts said, “TJ has a strong track record and deep expertise in mortgage credit investing, and we are pleased to welcome TJ into his expanded role as CIO. Additionally, Yong’s robust insights into the housing market and depth of experience in residential mortgage quantitative research serve as a great complement to TJ’s skills. MITT and its shareholders significantly benefit from TJ’s and Yong’s talent and dedication as Co-Portfolio Managers and their ability to generate attractive risk-adjusted returns over the long-term under a variety of market conditions and economic cycles.”

“We are very pleased with MITT’s financial performance during the third quarter,” said Chief Investment Officer, TJ Durkin. “Spreads for most Agency RMBS, Residential Investments and ABS Investments tightened during the quarter, driving the increase in book value. The Federal Reserve laid out its plan for implementing the gradual reduction of its balance sheet reinvestment, and this event allowed for Agency RMBS to realize their best spread performance of the year. Relatively rangebound interest rates, subdued implied volatility, robust demand and modest supply have continued to serve as a favorable backdrop for Agency RMBS and support our rotation of capital to the sector.”

INVESTMENT HIGHLIGHTS

$3.5 billion investment portfolio as of September 30, 2017 as compared to the $3.4 billion investment portfolio as of June 30, 2017⁽²⁾⁽³⁾

Net purchased $353.7 million of Agency and TBA securities, inclusive of unsettled trades, offset by net sales and payoffs of Credit Investments of $145.9 million

2.57% Net Interest Margin (“NIM”) as of September 30, 2017⁽⁷⁾

NIM increased primarily due to asset rotation from Credit Investments into Agency RMBS as overall cost of funds declined with increased use of lower cost Agency repos, which was only partially offset by the lower asset yield of Agency RMBS relative to Credit Investments

4.2x “At Risk” Leverage as of September 30, 2017⁽⁶⁾

Leverage remained flat due to the increase in equity from ATM proceeds and price appreciation, which offset the increase in financing

7.4% constant prepayment rate (“CPR”) on the Agency RMBS investment portfolio for the third quarter⁽⁵⁾

Trading activity during the quarter generated $7.9 mm of net equity

Invested $14.6 mm of net equity in Agency RMBS and TBA, offset by $22.5 mm of net equity generated from sales of Credit Investments

MITT, along with other Angelo, Gordon funds, participated in a term securitization in July which refinanced previously securitized non-performing mortgage loans into a new lower cost, fixed rate long-term financing

The Company maintained exposure to the securitization through an interest in the subordinated tranches as well as through its ownership of the vertical risk retention portion of the securitization

In Q3, MITT issued 361,000 shares of its common stock for net proceeds of $6.9 mm through its ATM Program

*Total funding cost and NIM includes cost of interest rate hedges.

**Total leverage ratio includes any net receivables on TBA and the leverage ratio by type is calculated based on allocated equity.

Premiums and discounts associated with purchases of the Company's securities are amortized or accreted into interest income over the estimated life of such securities, using the effective yield method. The Company recorded a $(0.2) million, or $(0.01) per share, retrospective adjustment due to the change in projected cash flows on its Agency RMBS, excluding interest-only securities and TBAs. Since the cost basis of the Company's Agency RMBS securities, excluding interest-only securities and TBAs, exceeds the underlying principal balance by 3.8% as of September 30, 2017, slower actual and projected prepayments can have a meaningful positive impact on the Company's asset yields, while faster actual or projected prepayments can have a meaningful negative impact on them.

FINANCING AND HEDGING ACTIVITIES

The Company, either directly or through its equity method investments in affiliates, had master repurchase agreements with 39 counterparties, under which it had debt outstanding with 28 counterparties as of September 30, 2017. The weighted average funding cost was 1.3% for Agency RMBS and 2.6% for Credit Investments. The investment portfolio is financed with repurchase agreements as of September 30, 2017 as summarized below:

NON-GAAP FINANCIAL MEASURE

This press release contains Core Earnings, a non-GAAP financial measure. Our management believes that this non-GAAP measure, when considered with our GAAP financials, provides supplemental information useful for investors in evaluating our results of operations. Our presentation of Core Earnings may not be comparable to similarly-titled measures of other companies, who may use different calculations. This non-GAAP measure should not be considered a substitute for, or superior to, the financial measures calculated in accordance with GAAP. Our GAAP financial results and the reconciliations from these results should be carefully evaluated.

We define Core Earnings, a non-GAAP financial measure, as net income/(loss) available to common stockholders excluding both unrealized and realized gains/(losses) on the sale or termination of securities and the related tax expense/benefit or disposition expense, if any, on such sale or termination including (i) investments held in affiliated entities and (ii) derivatives. As defined, Core Earnings include the net interest and other income earned on our investments on a yield adjusted basis, including credit derivatives, investments in debt and equity of affiliates, inverse Agency Interest-Only securities, interest rate derivatives, TBA drop income or any other investment activity that may earn or pay net interest or its economic equivalent. One of our objectives is to generate net income from net interest margin on the portfolio, and management uses Core Earnings to measure this objective. Management believes that this non-GAAP measure, when considered with our GAAP financials, provides supplemental information useful for investors in evaluating our results of operations. This metric, in conjunction with related GAAP measures, provides greater transparency into the information used by our management in its financial and operational decision-making.

A reconciliation of GAAP net income to Core Earnings for the three months ended September 30, 2017 and the three months ended September 30, 2016 is set forth below:

Footnotes

(1) Diluted per share figures are calculated using weighted average outstanding shares in accordance with GAAP. Per share figures are calculated using a denominator of all outstanding common shares including all shares granted to our Manager and our independent directors under our equity incentive plans as of quarter-end. Book value uses stockholders’ equity less net proceeds of the Company’s 8.25% Series A and 8.00% Series B Cumulative Redeemable Preferred Stock as the numerator.

(2) The investment portfolio at period end is calculated by summing the fair market value of our Agency RMBS, any long positions in TBAs, Residential Investments, Commercial Investments, and ABS Investments, including securities and mortgage loans owned through investments in affiliates, exclusive of AG Arc LLC. Refer to footnote (3) for more information on the GAAP accounting for certain items included in our investment portfolio. See footnote (13) for further details on AG Arc LLC.

(3) Generally, when we purchase a security and employ leverage, the security is included in our assets and the leverage is reflected in our liabilities on the balance sheet as either Repurchase agreements or Securitized debt. Throughout this press release where we disclose our investment portfolio and the related repurchase agreements that finance it, we have presented this information inclusive of (i) unconsolidated ownership interests in affiliates that are accounted for under GAAP using the equity method and (ii) long positions in TBAs, which are accounted for as derivatives under GAAP. This press release excludes investments through AG Arc LLC unless otherwise noted. This presentation of our investment portfolio is consistent with how our management evaluates the business, and we believe this presentation, when considered with the GAAP presentation, provides supplemental information useful for investors in evaluating our investment portfolio and financial condition. See footnote (13) for further details on AG Arc LLC.

(4) The economic return on equity for the quarter represents the change in book value per share from June 30, 2017 to September 30, 2017, plus the common dividends declared over that period, divided by book value per share as of June 30, 2017. The annualized economic return on equity is the quarterly return on equity multiplied by four.

(5) This represents the weighted average monthly CPRs published during the quarter for our in-place portfolio during the same period. Any net TBA position is excluded from the CPR calculation.

(6) “At Risk” Leverage was calculated by dividing total financing including any net TBA position by our GAAP stockholders’ equity at quarter-end. Total financing at quarter-end includes repurchase agreements inclusive of repurchase agreements through affiliated entities, exclusive of any financing utilized through AG Arc LLC, plus the payable on all unsettled buys less the financing on all unsettled sells, securitized debt and any net TBA position (at cost). Total financing excludes repurchase agreements and unsettled trades on U.S. Treasuries.

(7) Net interest margin is calculated by subtracting the weighted average cost of funds from the weighted average yield for the Company’s investment portfolio, which excludes cash held by the Company. See footnotes (8) and (9) for further detail. Net interest margin also excludes any net TBA position.

(8) The yield on our investment portfolio represents an effective interest rate, which utilizes all estimates of future cash flows and adjusts for actual prepayment and cash flow activity as of quarter-end. This calculation excludes cash held by the Company and excludes any net TBA position. The calculation of weighted average yield is weighted based on fair value.

(9) The cost of funds at quarter-end was calculated as the sum of (i) the weighted average funding costs on total financing outstanding at quarter-end and (ii) the weighted average of the net pay rate on our interest rate swaps, the net receive/pay rate on our Treasury long and short positions, respectively, and the net receivable rate on our IO index derivatives, if any. Both elements of the cost of funds at quarter-end were weighted by the outstanding repurchase agreements and securitized debt outstanding at quarter-end, excluding repurchase agreements associated with U.S. Treasury positions. The cost of funds excludes any net TBA position.

(10) The management fee percentage at quarter-end was calculated by annualizing management fees recorded during the quarter and dividing by quarter-end stockholders’ equity.

(11) The other operating expenses percentage at quarter-end was calculated by annualizing other operating expenses recorded during the quarter and dividing by quarter-end stockholders’ equity.

(12) This estimate of undistributed taxable income per share represents the total estimated undistributed taxable income as of quarter-end. Undistributed taxable income is based on current estimates and projections. As a result, the actual amount is not finalized until we file our annual tax return, typically in September of the following year.

(13) The Company invests in Arc Home LLC through AG Arc LLC, one of its indirect subsidiaries.

(14) The Company allocates its equity by investment using the fair market value of its investment portfolio, less any associated leverage, inclusive of any long TBA position (at cost). The Company allocates all non-investment portfolio related items based on their respective characteristics in order to sum to the Company’s stockholders’ equity per the consolidated balance sheets. The Company’s equity allocation method is a non-GAAP methodology and may not be comparable to similarly titled measures or concepts of other companies, who may use different calculations.
