FINANCIAL HIGHLIGHTS

INVESTMENT HIGHLIGHTS

SECOND QUARTER 2012 RESULTS

AG Mortgage Investment Trust, Inc. is an actively managed REIT that opportunistically invests in a diversified risk-adjusted portfolio of Agency RMBS, Non-Agency RMBS, ABS and CMBS. For the second quarter 2012, the Company had net income of $44.9 million, or $2.85 per diluted share (8), and Core Earnings of $13.5 million, or $0.86 per diluted share. Core Earnings represents a non-GAAP financial measure and is defined as net income (loss) excluding (i) net realized gain (loss) on investments and terminations on derivative contracts and (ii) net unrealized appreciation (depreciation) on investments and derivative contracts. (See “Non-GAAP Financial Measure” below for further detail on Core Earnings)

“We’re extremely pleased with our second quarter performance as the investment team achieved our objectives of increased book value while delivering an attractive dividend for our shareholders” said David Roberts, Chief Executive Officer. “Furthermore, we are proud that we have increased our core earnings quarter over quarter since inception of the Company. With additional undistributed taxable income of $0.74 per share, we have built up a significant earnings reserve against potential future dividend payments. As we look at the investment opportunity set and the origination capabilities of our manager, Angelo Gordon, we see an investment environment very conducive to grow book value and deploy capital in an accretive fashion. We have already taken the first step towards this goal with our successful issuance of Preferred Stock.”

“With respect to the composition of our portfolio we have been very pleased with the actual prepayments experienced by our overall Agency book” said Jonathan Lieberman, Chief Investment Officer. “Over the quarter we were able to take advantage of the flows in the market to increase our exposure to credit investments to over 16%. We expect to take advantage of our ability to be nimble and respond to market conditions over the coming months to further increase the credit component of our overall portfolio.”

SUBSEQUENT EVENT

On August 3, 2012, the Company completed a preferred offering of 1,800,000 shares of 8.25% Series A Cumulative Redeemable Preferred Stock at a liquidation preference of $25.00 per share. The Company received gross proceeds of approximately $45.0 million. Net proceeds to the Company from the offering were approximately $43.6 million, net of issuance costs of approximately $1.4 million. The Company has granted the underwriters an over-allotment option of 270,000 shares. If exercised in full, additional net proceeds to the Company will be $6.5 million.

“After the end of the quarter we raised $43.6 million of net proceeds via a preferred offering that we believe not only offered an extremely attractive return for the preferred shareholders but was also accretive for our common stockholders,” said Frank Stadelmaier, Chief Financial Officer.

KEY STATISTICS (4)

INVESTMENT PORTFOLIO

The following summarizes the Company’s investment portfolio as of June 30, 2012 (4):

As of June 30, 2012, the weighted average yield on the Company’s investment portfolio was 3.54% and its weighted average cost of funds was 0.99%. This resulted in a net interest margin of 2.55% as of June 30, 2012. (5)

The Company had net realized gains of $7.6 million during the quarter ended June 30, 2012. Of this amount, $6.4 million, or $0.41 per share was from sales of Agency RMBS and TBAs, $1.5 million, or $0.10 per share was from sales of credit investments and $(0.3) million, or $(0.03) per share was from the net settlement of interest rate swaps. The Company had year-to-date net realized gains of $10.0 million. Of this amount, $7.8 million, or $0.52 per share was from sales of Agency RMBS and TBAs, $2.4 million, or $0.16 per share was from sales of credit investments and $(0.2) million, or $(0.01) per share was from the net settlement of interest rate swaps.

The CPR for the Agency RMBS portfolio was 5.5% for the second quarter and 5.1% for the month of June 2012. The 2012 year-to-date CPR on the Agency RMBS portfolio was 5.0%. (7)

The weighted average cost basis of the Agency investment portfolio, excluding interest-only securities, was 104.0% as of June 30, 2012. The amortization of premiums (net of any accretion of discounts) on Agency securities for the second quarter was $4.0 million, or $(0.25) per share, of which $0.7 million or $(0.05) per share of retrospective adjustment resulted due to the change in projected cash flows on our bonds. The Company recorded year-to-date premium amortization of $6.7 million, or $(0.45) per share. The unamortized net Agency premium as of June 30, 2012 was $82.0 million.

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. Since the cost basis of the Company’s Agency securities, excluding interest-only securities, exceeds the underlying principal balance by 4.0% as of June 30, 2012, slower actual and projected prepayments can have a meaningful positive impact, while faster actual or projected prepayments can have a meaningful negative impact on the Company’s asset yields.

LEVERAGE AND HEDGING ACTIVITIES

The investment portfolio is financed with repurchase agreements as of June 30, 2012 as summarized below:

Currently, the Company entered into repurchase agreements with 26 counterparties. We continue to rebalance our exposures to counterparties and add new counterparties.

On April 9, 2012, AG MIT, LLC (“AG MIT”), a direct, wholly-owned subsidiary of the Company, entered into a Master Repurchase and Securities Contract (the “Repurchase Agreement”) with Wells Fargo Bank, National Association to finance AG MIT’s acquisition of certain residential, non-Agency Securities. Each transaction under the Repurchase Agreement will have its own specific terms, such as identification of the assets subject to the transaction, sale price, repurchase price and rate. The Repurchase Agreement provides for a 364-day facility with an aggregate maximum borrowing capacity of $75 million and is set to mature on April 8, 2013, and may be extended for an additional 90 days.

We have entered into interest rate swap agreements to hedge our portfolio. The Company’s swaps as of June 30, 2012 are summarized as follows:

* Approximately 13% of our receive float interest rate swap notionals reset monthly based on one-month LIBOR and 87% of our receive float interest rate swap notionals reset quarterly based on three-month LIBOR.

TAXABLE INCOME

The primary differences between taxable income and GAAP net income include (i) unrealized gains and losses associated with investment and derivative portfolios are marked-to-market in current income for GAAP purposes, but excluded from taxable income until realized or settled, (ii) temporary differences related to amortization of net premiums paid on investments, (iii) the timing and amount of deductions related to stock-based compensation, and (iv) excise taxes. As of June 30, 2012, the Company had undistributed taxable income of approximately $1.17 per share.

DIVIDEND

NON-GAAP FINANCIAL MEASURE

This press release contains Core Earnings, a non-GAAP financial measure. AG Mortgage Investment Trust’s management believes that this non-GAAP measure, when considered with GAAP, provides supplemental information useful in evaluating the results of the Company’s operations. This non-GAAP measure should not be considered a substitute, 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.

Core Earnings are defined by the Company as net income excluding both realized and unrealized gains (losses) on the sale or termination of securities, including underlying linked transactions and derivatives. As defined, Core Earnings include the net interest earned on these transactions, including credit derivatives, linked transactions, inverse Agency securities, interest rate derivatives or any other investment activity that may earn net interest. One of the objectives of the Company is to generate net income from net interest margin on the portfolio and management uses Core Earnings to measure this objective.

A reconciliation of GAAP net income to Core Earnings for the three and six months ended June 30, 2012 and the period from March 7, 2011 to June 30, 2011 is set forth below:

NM = not meaningful

Footnotes

(1)   Per share figures are calculated using outstanding shares including all shares granted to our Manager and our independent directors under our equity incentive plans as of quarter end.

(2)   Return to investors is calculated by taking the change in investment value divided by original cost. Original cost is equal to the Initial Public Offering price (“IPO price”) and the change in investment value is equal to the change from our IPO price to the closing price on the last business day of the current quarter plus dividends declared.

(3)   Return on equity during the quarter is calculated by dividing net income at quarter end by stockholders’ equity at the beginning of the quarter.

(4)   Generally when we purchase a security and finance it with a repurchase agreement, the security is included in our assets and the repurchase agreement is separately reflected in our liabilities on our balance sheet. For securities with certain characteristics (including those which are not readily obtainable in the market place) that are purchased and then simultaneously sold back to the seller under a repurchase agreement, US GAAP requires these transactions be netted together and recorded as a forward purchase commitment. Throughout this press release where we disclose our investment portfolio and the repurchase agreements that finance it, including our leverage metrics, we have un-linked the transaction and used the gross presentation as used for all other securities. This presentation is consistent with how the Company’s management evaluates the business, and believes provides the most accurate depiction of the Company’s investment portfolio and financial condition.

(5)   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 (11) and (12) for further detail.

(6)   The total investment portfolio is calculated by summing the fair market value of our Agency RMBS, Non-Agency RMBS, ABS and CMBS assets, including linked transactions. The percentage of Agency RMBS and credit investments are calculated by dividing the respective fair market value of each, including linked transactions, by the total investment portfolio.

(7)   This represents the weighted average monthly CPRs published during the quarter for our in-place portfolio during the same period.

(8)   Diluted per share figures are calculated using weighted average outstanding shares in accordance with GAAP.

(9)   The leverage ratio during the quarter was calculated by dividing our daily weighted average repurchase agreements, including those included in linked transactions, for the period by the weighted average stockholders’ equity for the period. The leverage ratio at quarter end was calculated by dividing total repurchase agreements, including repurchase agreements accounted for as linked transactions, plus the net payable/receivable on unsettled trades on our GAAP balance sheet by our GAAP stockholders’ equity.

(10) The swap ratio during the quarter was calculated by dividing our daily weighted average swap notionals, excluding forward starting swaps and including receive fixed swap notionals as negative values, for the period by our daily weighted average repurchase agreements, including those included in linked transactions. The swap ratio at quarter end was calculated by dividing the notional value of our interest rate swaps by total repurchase agreements, including those included in linked transactions, plus the net payable/receivable on unsettled trades.

(11) 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. The yield on our investment portfolio during the quarter was calculated by annualizing interest income for the quarter and dividing by our daily weighted average securities held. This calculation excludes cash held by the Company.

(12) The cost of funds during the quarter was calculated by annualizing the sum of our interest expense and our net pay rate of our interest rate swaps, and dividing by our daily weighted average repurchase agreements for the period. The cost of funds at quarter end was calculated as the sum of the weighted average rate on the repurchase agreements outstanding at quarter end and the weighted average net pay rate on our interest rate swaps. Both elements of the cost of funds at quarter end were weighted by the repurchase agreements outstanding at quarter end.

(13) The management fee percentage during the quarter was calculated by annualizing the management fees incurred during the quarter and dividing by the weighted average stockholders’ equity for the quarter. The management fee percentage at quarter end was calculated by annualizing management fees incurred during the quarter and dividing by quarter-ended stockholders’ equity.

(14) The other operating expenses percentage during the quarter was calculated by annualizing the other operating expenses incurred during the quarter and dividing by our weighted average stockholders’ equity for the quarter. The other operating expenses percentage at quarter end was calculated by annualizing other operating expenses recorded during the quarter and dividing by quarter-ended stockholders’ equity.
