Organization

AG Mortgage Investment Trust, Inc. (the "Company" or "MITT") is a residential mortgage REIT with a focus on investing in a diversified risk-adjusted portfolio of residential mortgage-related assets in the U.S. mortgage market. The Company’s investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans within the non-agency segment of the housing market. The Company obtains its assets through Arc Home, LLC ("Arc Home"), a residential mortgage loan originator in which the Company owns an approximate 44.6% interest, and through other third-party origination partners.

On December 6, 2023, the Company acquired Western Asset Mortgage Capital Corporation ("WMC"), an externally managed mortgage REIT that focused on investing in, financing and managing a portfolio of residential mortgage loans, real estate related securities, and commercial real estate loans. For more information, refer to the "WMC Acquisition" section below.

The Company’s assets, excluding its ownership in Arc Home, include Residential Investments, Agency RMBS and Legacy WMC Commercial Investments. Currently, its Residential Investments primarily consist of newly originated Non-Agency Loans, Agency-Eligible Loans, and Home Equity Loans. The Company may invest in other types of residential mortgage loans and other mortgage related assets. The Company also invests in Residential Investments through its unconsolidated ownership interests in affiliates which are included in the "Investments in debt and equity of affiliates" line item on its consolidated balance sheets.

The Company's asset classes are primarily comprised of the following:

Asset Class	Description
Residential Investments
Non-Agency Loans(1)	•Non-Agency Loans are loans that do not conform to the underwriting guidelines of a government-sponsored enterprise ("GSE"). Non-Agency Loans consist of Qualified mortgage loans ("QM Loans") and Non-Qualified mortgage loans ("Non-QM Loans"). QM Loans are residential mortgage loans that comply with the Ability-To-Repay rules and related guidelines of the Consumer Finance Protection Bureau.
Agency-Eligible Loans(1)	•Agency-Eligible Loans are loans that are underwritten in accordance with GSE guidelines and are primarily secured by investment properties, but are not guaranteed by a GSE. Although these loans are underwritten in accordance with GSE guidelines and can be delivered to Fannie Mae and Freddie Mac, the Company includes these loans within its Non-Agency securitizations.
Home Equity Loans(1)	•Home Equity Loans are revolving lines of credit or closed-end loans secured primarily by a second lien on a residential mortgaged property which provide borrowers access to the equity in their home without the need to pay off their existing mortgage. Home Equity Loans that are structured as revolving lines of credit generally have an initial draw period of 3 to 5 years, and after the initial draw period ends, the loans generally convert to 15- or 25-year amortizing loans.
Re- and Non-Performing Loans(1)	•Performing, re-performing, and non-performing loans are residential mortgage loans collateralized by a first lien mortgaged property.
Non-Agency RMBS(2)	•Non-Agency Residential Mortgage-Backed Securities ("RMBS") represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government.
Agency RMBS(2)	•Agency RMBS represent interests in pools of residential mortgage loans guaranteed by a GSE such as Fannie Mae or Freddie Mac, or an agency of the U.S. Government such as Ginnie Mae.
Legacy WMC Commercial Investments(3)
Commercial Loans	•Commercial loans represent first lien commercial mortgage loans participations.
CMBS(2)	•Commercial Mortgage-Backed Securities ("CMBS") represent investments of fixed-rate and floating-rate CMBS, secured by, or evidencing an ownership interest in, a single commercial mortgage loan or a pool of commercial mortgage loans.

(1)These investments are included in the "Securitized residential mortgage loans, at fair value" or "Residential mortgage loans, at fair value" line items on the consolidated balance sheets.

(2)These investments are included in the "Real estate securities, at fair value" line item on the consolidated balance sheets.

(3)The Company's investments include commercial loans, CMBS and other securities (collectively, the "Legacy WMC Commercial Investments") that were acquired in the WMC acquisition. The Company expects to either hold the Legacy WMC Commercial Investments until maturity or opportunistically exit these investments.

The Company conducts its business through one reportable segment, Loans and Securities, which reflects how the Company manages its business and analyzes and reports its results of operations.

The Company was incorporated in the state of Maryland on March 1, 2011 and commenced operations in July 2011. The Company conducts its operations to qualify and be taxed as a real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). The Company is externally managed by AG REIT Management, LLC, a Delaware limited liability company (the "Manager"), a wholly-owned subsidiary of Angelo, Gordon & Co., L.P. ("TPG Angelo Gordon"), a diversified credit and real estate investing platform within TPG Inc. ("TPG"). The Manager has delegated to TPG Angelo Gordon the overall responsibility of its day-to-day duties and obligations arising under the management agreement.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

WMC Acquisition

On December 6, 2023 (the "Closing Date"), the Company completed its acquisition of WMC, a Delaware corporation. WMC was an externally managed mortgage REIT that focused on investing in, financing and managing a portfolio of residential mortgage loans, real estate related securities, and commercial real estate loans. On the Closing Date, WMC merged with and into AGMIT Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Merger Sub"), with Merger Sub continuing as the surviving company (the "Merger"). As contemplated by the Agreement and Plan of Merger, dated as of August 8, 2023 (the "Merger Agreement"), the certificate of merger was filed with the Secretary of State of the State of Delaware, and the Merger was effective at 8:15 a.m., Eastern Time, on the Closing Date (the "Effective Time").

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, at the Effective Time, each outstanding share of WMC common stock, par value $0.01 per share ("WMC Common Stock"), was converted into the right to receive the following (the "Per Share Merger Consideration"): (i) from MITT, 1.498 shares of MITT common stock; and (ii) from the Manager, a cash amount equal to $0.92 (the "Per Share Additional Manager Consideration"). No fractional shares of MITT common stock were issued in the Merger, and the value of any fractional interests to which a former holder of WMC Common Stock was otherwise entitled was paid in cash.

Pursuant to the Merger Agreement, the amount of the Per Share Additional Manager Consideration was reduced by the smallest amount (rounded to the nearest cent) necessary to cause the Per Share Additional Manager Consideration to be less than 10% of the total value of the Per Share Merger Consideration received by a holder of WMC Common Stock under the Merger Agreement. Pursuant to the previously disclosed amendment to the Company's management agreement, dated as of August 8, 2023, by and between MITT and the Manager (the "MITT Management Agreement Amendment"), which became effective on the Closing Date and amends the existing management agreement, dated as of June 29, 2011 (as amended, the "Existing MITT Management Agreement"), (i) the Manager will waive its right to seek reimbursement from MITT for any expenses otherwise reimbursable by MITT under the Existing MITT Management Agreement in an amount equal to approximately $1.3 million, which is the excess of $7.0 million over the aggregate Per Share Additional Manager Consideration paid by the Manager to the holders of WMC Common Stock under the Merger Agreement, and (ii) the Manager’s base management fee will be reduced by $0.6 million for the first four quarters following the Effective Time, beginning with the fiscal quarter in which the Effective Time occurred (i.e., resulting in an aggregate $2.4 million waiver of base management fees).

Additionally, each outstanding share of WMC’s restricted common stock and each WMC restricted stock unit (each, a "WMC Equity Award") vested in full immediately prior to the Effective Time and, as of the Effective Time, was considered outstanding for all purposes of the Merger Agreement, including the right to receive the Per Share Merger Consideration, except that WMC Equity Awards granted to certain members of the WMC board of directors at WMC’s 2023 annual stockholders’ meeting (collectively, the "2023 WMC Director Awards") were treated as follows: (i) for M. Christian Mitchell and Lisa G. Quateman, who were appointed to the MITT board of directors as of the Effective Time, the 2023 WMC Director

Awards were equitably adjusted effective as of the Effective Time into awards relating to shares of MITT common stock that have the same value, vesting terms and other terms and conditions as applied to the corresponding WMC restricted stock units immediately prior to the Effective Time and (ii) for the other members of the WMC board of directors, the 2023 WMC Director Awards accelerated and vested pro-rata effective as of immediately prior to the Effective Time based on a fraction, the numerator of which was 166 (the number of days between the grant date and the Closing Date) and the denominator of which was 365, and the remaining unvested portion of such 2023 WMC Director Awards was cancelled without any consideration.

Pursuant to the Merger Agreement, approximately 9.2 million shares of MITT common stock were issued to former WMC common stockholders and, following the consummation of the Merger, former WMC common stockholders owned approximately 31% of the common equity of MITT.

Purchase Price Allocation

The Company completed the WMC acquisition on December 6, 2023 to support continued growth of the Company and to create efficiency and scale for stockholders. The Company accounted for this transaction in accordance with Accounting Standards Codification ("ASC") 805, "Business Combinations" using the acquisition method of accounting, which requires, among other things, that the assets acquired and liabilities assumed be recognized at fair value as of the acquisition date. The following table summarizes the allocation of the total consideration paid to acquire the assets and assume the liabilities of WMC (in thousands, except exchange ratio and per share amounts).

Consideration
WMC shares outstanding at December 5, 2023 (1)	6,143
Exchange Ratio	1.498
Shares of MITT Common Stock Issued	9,202
MITT Common Stock Price as of December 5, 2023	$	5.56
MITT Total Consideration (2)	$	51,163
Assets
Securitized residential mortgage loans (3)	$	971,781
Residential mortgage loans (3)	6,046
Commercial loans	78,459
Non-Agency RMBS	48,200
CMBS	56,301
Other securities	1,159
Agency RMBS	745
Cash and cash equivalents	5,316
Restricted cash	873
Other assets	24,654
Total Assets	$	1,193,534
Liabilities
Securitized debt	$	837,317
Financing arrangements	171,170
Convertible senior unsecured notes	85,172
Other liabilities	18,522
Total Liabilities	$	1,112,181
Net Assets Acquired	$	81,353
Bargain purchase gain	$	30,190

(1)For time-based restricted stock units granted by WMC that fully vested as of the Closing Date, the fair value of the Company’s common stock issued in the satisfaction of these units was included in equity consideration transferred as no post acquisition service was required.

(2)MITT Total Consideration does not include the Per Share Additional Manager Consideration paid by the Manager to former holders of WMC Common Stock.

(3)The unpaid principal balance of residential mortgage loans acquired in connection with the Merger was $1.1 billion.

The fair value of the assets acquired and liabilities assumed required the use of significant assumptions and estimates. Critical estimates included, but were not limited to, future expected cash flows related to these assets and liabilities and the applicable discount rates. These estimates were based on assumptions that management believes to be reasonable; however, actual results may differ from these estimates. The assessment of fair value is based on information that was available to management at the time the consolidated financial statements were prepared. Those estimates and assumptions are subject to change as management obtains additional information related to those estimates during the applicable measurement period. The final determination must occur within one year of the acquisition date.

Under the acquisition method of accounting, merger-related transaction costs (such as advisory, legal, valuation, and other professional fees) are not included as components of consideration transferred but are expensed in the periods in which the costs are incurred. The Company incurred transaction costs of $4.9 million and $1.1 million during the third and fourth quarters of 2023, respectively, which were included in the "Transaction related expenses" line item in the consolidated statements of operations.

At acquisition, the Company recognized a bargain purchase gain of $30.2 million which was separately recorded in the consolidated statements of operations. The bargain purchase gain represents the amount by which the fair value of the net assets acquired in the acquisition exceeds the fair value of the shares of MITT common stock issued as consideration at the Effective Time. As a result of macroeconomic factors and interest rate volatility, the prices per share of common stock of certain companies within the mortgage REIT industry have traded at discounts to book values per share in recent periods, which contributed to the bargain purchase gain recorded on the WMC acquisition.

Unaudited Supplemental Pro Forma Financial Information

The following table presents unaudited pro forma combined interest income and net income/(loss) available to common stockholders for the nine months ended September 30, 2023 prepared as if the Merger had been consummated on January 1, 2022 (in thousands).

	Nine months ended September 30, 2023
Interest income	$	239,249
Net Income/(Loss) Available to Common Stockholders	(4,481)

The unaudited supplemental pro forma financial information for the nine months ended September 30, 2023 includes adjustments to reflect the deconsolidation of certain variable interest entities ("VIE") held by WMC, as well as adjustments to management fees and certain other expenses. In addition, for the year ended December 31, 2022, the pro-forma financial information includes adjustments related to any bargain purchase gain and transaction related expenses. The unaudited supplemental pro forma financial information does not include any anticipated expense synergies or other anticipated benefits of the Merger and, accordingly, the unaudited supplemental pro forma financial information is not necessarily indicative of either future results of operations or results that might have been achieved had the Merger occurred on January 1, 2022.
