1. Organization

AG Mortgage Investment Trust, Inc. (the "Company") 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.

The Company’s assets, excluding its ownership in Arc Home, include Residential Investments and Agency RMBS. Currently, its Residential Investments primarily consist of newly originated Non-Agency Loans and Agency-Eligible 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.
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 Residential Mortgage-Backed Securities ("RMBS")(2)	•Non-Agency RMBS represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. The mortgage loan collateral consists of either Non-Agency Loans or Agency-Eligible Loans.
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.

(1)These investments are included in the "Securitized residential mortgage loans, at fair value," "Securitized residential mortgage loans held for sale, at fair value," "Residential mortgage loans, at fair value," and "Residential mortgage loans held for sale, 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.

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. ("Angelo Gordon"), a privately-held, SEC-registered investment adviser. The Manager has delegated to Angelo Gordon the overall responsibility of its day-to-day duties and obligations arising under the management agreement.

Notes to Consolidated Financial Statements (Unaudited)

June 30, 2023

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.

2. Summary of significant accounting policies

Consolidation and basis of presentation

The accompanying unaudited consolidated financial statements and related notes have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. For the three months ended June 30, 2022, the Company reclassified $2.5 million and $1.3 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. For the six months ended June 30, 2022, the Company reclassified $5.2 million and $2.3 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. Furthermore, for the three and six months ended June 30, 2022, the Company reclassified $1.0 million and $2.0 million of servicing fees into the "Investment related expenses" line item on the consolidated statement of operations, respectively. These expenses were reclassified to conform to the current year presentation of expenses. In the opinion of management, all adjustments considered necessary for a fair statement of the Company’s financial position, results of operations, and cash flows have been included for the interim period and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year.

Significant accounting policies

There have been no significant changes to the Company's accounting policies included in Note 2 to the consolidated financial statements of the Company’s Form 10-K for the year ended December 31, 2022. These unaudited consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2022 included in the Company’s Form 10-K.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.

Investment consolidation

An entity is a variable interest entity ("VIE") if the equity investors (i) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (ii) are unable to direct the entity’s activities or (iii) are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of Accounting Standards Codification ("ASC") 810-10, "Consolidation" are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company determines that consolidation is not required, it will then assess whether the transfer of the underlying assets would qualify as a sale, should be accounted for as secured financings under GAAP, or should be accounted for as an equity method investment, depending on the circumstances.

A Special Purpose Entity ("SPE") is an entity designed to fulfill a specific limited need of the company that organized it. SPEs are often used to facilitate transactions that involve securitizing financial assets or resecuritizing previously securitized financial assets. The objective of such transactions may include obtaining non-recourse financing, obtaining liquidity or refinancing the underlying securitized financial assets on improved terms. Securitization involves transferring assets to an SPE to convert all or a portion of those assets into cash before they would have been realized in the normal course of business through the SPE’s issuance of debt or equity instruments. Investors in an SPE usually have recourse only to the assets in the SPE and depending on the overall structure of the transaction, may benefit from various forms of credit enhancement, such as over-collateralization

in the form of excess assets in the SPE, priority with respect to receipt of cash flows relative to holders of other debt or equity instruments issued by the SPE, or a line of credit or other form of liquidity agreement that is designed with the objective of ensuring that investors receive principal and/or interest cash flow on the investment in accordance with the terms of their investment agreement.

The Company enters into securitization transactions collateralized by its Non-Agency Loans/Agency-Eligible Loans and re- and non-performing loans (the trusts in which these loans are deposited are referred to as "Non-Agency VIEs" and "RPL/NPL VIEs", respectively, and collectively "Residential Mortgage Loan VIEs"), which may result in the Company consolidating the respective VIEs that are created to facilitate these securitizations. Based on the evaluations of each VIE, the Company may conclude that the VIEs should be consolidated and, as a result, transferred assets of these VIEs would be determined to be secured borrowings. Upon consolidation, the Company elected the fair value option pursuant to ASC 825 for the assets and liabilities of the Residential Mortgage Loan VIEs. Electing the fair value option allows the Company to record changes in fair value in the consolidated statement of operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all activities will be recorded in a similar manner. The Company applied the guidance under ASC 810-10 (Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity) whereby the Company determines whether the fair value of the assets or liabilities of the Residential Mortgage Loan VIEs are more observable as a basis for measuring the less observable financial instruments. The Company has determined that the fair value of the liabilities of the Residential Mortgage Loan VIEs are more observable since the prices for these liabilities are more easily determined as similar instruments trade more frequently on a relative basis than the individual assets of the VIEs. See Note 3 for more detail regarding the Residential Mortgage Loan VIEs and Note 5 for more detail related to the Company's determination of fair value for the assets and liabilities included within these VIEs.

Recent accounting pronouncements

In March 2020, FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting and may be elected over time as reference rate reform activities occur. This ASU is effective as of March 12, 2020 and was amended by ASU 2022-06 to sunset on December 31, 2024. The ASU applies to all entities that have contracts, hedging relationships and other transactions that reference LIBOR and certain other reference rates that are expected to be discontinued. However, it cannot be applied to contract modifications that occur after December 31, 2024. With certain exceptions, this ASU also cannot be applied to hedging relationships entered into or evaluated after that date. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance.

As of June 30, 2023, the Company has transitioned from LIBOR to an alternative benchmark. The adoption of ASU 2020-04 and the LIBOR transition did not have a material impact on the consolidated financial statements. The Company's primary exposure to LIBOR has historically included its financing arrangements and derivative contracts. In addition, the Company's Series C Preferred Stock is set to transition to a floating rate in September of 2024. As of June 30, 2023, the Company no longer has derivative contracts indexed to LIBOR and all LIBOR-based financing arrangements have transitioned to alternative benchmark rates. The Company does not currently intend to amend the Series C Preferred Stock to change the existing LIBOR cessation fallback language.

Unconsolidated variable interest entities

The Company's Non-Agency RMBS includes certain securities retained from a rated Non-QM Loan securitization the Company participated in alongside a private fund under the management of Angelo Gordon. Upon evaluating its investment in the VIE, the Company determined it was not the primary beneficiary and, as a result, did not consolidate the securitization trust. The Company has a 40.9% interest in the retained subordinate tranches which represents its continuing involvement in the securitization trust.

The following table summarizes the Company’s investment in unconsolidated VIEs as of June 30, 2023 and December 31, 2022 (in thousands).

	June 30, 2023				December 31, 2022

(1)Interest Only have no principal balances and bear interest based on a notional balance. The notional balance is used solely to determine interest distributions on the interest only classes of securities. As of June 30, 2023 and December 31, 2022, the notional balances for the Non-Agency RMBS Interest Only line item were $101.3 million and $108.5 million, respectively.

(2)Maximum loss exposure from the Company’s involvement with unconsolidated VIEs pertains to the fair value of the securities retained from these VIEs. The Company has no obligation to provide any other explicit or implicit support to the securitization trust.

(3)As of June 30, 2023 and December 31, 2022, the Company held securities exposed to the first loss of the securitization with a fair value of $2.9 million and $4.1 million, respectively.

5. Fair value measurements

The fair value of the Company's financial instruments is determined in accordance with the provisions of ASC 820, "Fair Value Measurements and Disclosures." When possible, the Company determines fair value using third-party data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices and may include quoted prices for similar assets and liabilities in active markets. Level 3 inputs are significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used and reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.

The valuation of the Company’s residential mortgage loans, securitized debt relating to the Residential Mortgage Loan VIEs, certain securities, and forward purchase commitments is determined by the Manager using third-party pricing services where available, valuation analyses from third-party pricing service providers, or model-based pricing. Third-party pricing service providers conduct independent valuation analyses based on a review of source documents, available market data, and comparable investments. The analyses provided by valuation service providers are reviewed and considered by the Manager. The evaluation considers the underlying characteristics of each loan, which are observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company also considers loan servicing data, as available, forward interest rates, general economic conditions, home price index forecasts, and valuations of the underlying properties. The variables considered most significant to the determination of the fair value of the Company's residential mortgage loans, securitized debt, and forward purchase commitments include market-implied discount rates, projections of default rates, delinquency rates, prepayment rates, loss severity, recovery rates, reperformance rates, timeline to liquidation, and, for forward purchase commitments, pull-through rates. The Company and third-party pricing service providers use loan level data and macro-economic inputs to generate loss adjusted cash flows and other information in determining the fair value. Because of the inherent uncertainty of such valuation, the fair value established for mortgage loans, securitized debt, and forward purchase commitments held by the Company may differ from the fair value that would have been established if a ready market existed for these mortgage loans.

Fair values for the Company’s securities and derivatives may be based upon prices obtained from third-party pricing services or broker quotations. The valuation methodology of the Company’s third-party pricing services incorporates commonly used market pricing methods, including a spread measurement to various indices, which are observable inputs. The evaluation also considers the underlying characteristics of each investment, which are also observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company collects and considers current market intelligence on all major markets, including benchmark security evaluations and bid-lists from various sources, when available. As part of the Company’s risk management process, the Company reviews and analyzes all prices obtained by comparing prices to recently completed transactions involving the same or similar investments on or near the reporting date. If, in the opinion of the Manager, one or more prices reported to the Company are not reliable or unavailable, the Manager reviews the fair value based on characteristics of the investment it receives from the issuer and available market information.

The Company's investment in Arc Home is evaluated on a periodic basis using a market approach. In applying the market approach, fair value is determined by multiplying Arc Home's book value by a relevant valuation multiple observed based on a range of comparable public entities or transactions, adjusted by management as appropriate for differences between the investment and the referenced comparables. The evaluation also considers the underlying financial performance of Arc Home, general economic conditions, and relevant trends within the mortgage banking industry.

Changes in the market environment and other events that may occur over the life of these investments may cause the gains or losses ultimately realized to be different than the valuations currently estimated. The significant unobservable inputs used in the fair value measurement of the Company’s loans and securities are yields, prepayment rates, probability of default, and loss severity in the event of default. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates. The significant unobservable input used in the fair value measurement of the Company’s investment in Arc Home is the book value multiple. Significant increases (decreases) in the multiple applied would result in a significantly higher (lower) fair value measurement.

The Company did not have any transfers of assets or liabilities between Levels 1 and 2 of the fair value hierarchy during the three and six months ended June 30, 2023 and 2022.

The Company did not have any transfers between the Levels 2 and 3 of the fair value hierarchy during the three and six months ended June 30, 2023 and 2022. Transfers into the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of reduced levels of market transparency. Transfers out of the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of increased levels of market transparency. Indications of increases or decreases in levels of market transparency include a change in observable transactions or executable quotes involving these instruments or similar instruments. Changes in these indications could impact price transparency, and thereby cause a change in level designations in future periods.

(1)As of June 30, 2023, the Company's pay fix/receive float interest rate swaps had a weighted average pay-fixed rate of 3.75%, a weighted average receive-variable rate of 5.09%, and a weighted average years to maturity of 4.28 years. As of December 31, 2022, the Company's pay fix/receive float interest rate swaps had a weighted average pay-fixed rate of 2.77%, a weighted average receive-variable rate of 4.30%, and a weighted average years to maturity of 4.77 years.

Derivative and other instruments eligible for offset are presented gross on the consolidated balance sheets as of June 30, 2023 and December 31, 2022, if applicable. The Company has not offset or netted any derivatives or other instruments with any financial instruments or cash collateral posted or received.

The Company must post cash or securities as collateral on its derivative instruments when their fair value declines. This typically occurs when prevailing market rates change adversely, with the severity of the change also dependent on the term of the derivatives involved. The posting of collateral is generally bilateral, meaning that if the fair value of the Company’s derivatives increases, its counterparty must post collateral. As of June 30, 2023, the Company's restricted cash balance included $15.7 million of collateral related to certain derivatives, of which $5.6 million represents cash collateral posted by the Company and $10.1 million represents amounts related to variation margin. As of December 31, 2022, the Company's restricted cash balance included $9.6 million of collateral related to certain derivatives, of which $1.3 million represents cash collateral posted by the Company and $8.3 million represents amounts related to variation margin.

9. Income taxes

The Company conducts its operations to qualify and be taxed as a REIT. As a REIT, the Company is not subject to federal income tax to the extent that it makes qualifying distributions to its stockholders, and provided it satisfies on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution, and stock ownership tests. The state and local tax jurisdictions for which the Company is subject to tax-filing obligations recognize the Company’s status as a REIT, and therefore, the Company generally does not pay income tax in such jurisdictions. The Company may, however, be subject to certain minimum state and local tax filing fees as well as certain excise, franchise, or business taxes.

Excise tax represents a non-deductible 4% tax on the required amount of the Company’s ordinary income and net capital gains not distributed during the year. The expense is calculated in accordance with applicable tax regulations. For the three and six months ended June 30, 2023 and 2022, the Company did not record any excise tax.

Taxable REIT Subsidiaries

The Company elected to treat certain domestic subsidiaries as taxable REIT subsidiaries ("TRSs"). The Company’s financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. Currently, the Company has wholly owned domestic TRSs that are taxable as corporations and subject to U.S. federal, state, and local income tax on net income at the applicable corporate rates. The federal statutory rate for the three and six months ended June 30, 2023 and 2022 was 21%. The Company’s effective tax rate differs from its combined U.S. federal, state, and local corporate statutory tax rate primarily due to income earned at the REIT, which is not subject to tax, due to the deduction for qualifying distributions made by the Company, and any change in the valuation allowance as disclosed in further detail below. The tax expense attributable to its TRS is recorded in the "Non-investment related expenses" line item on the consolidated statement of operations. The below table details the tax expense attributable to the TRS for the three and six months ended June 30, 2023 and 2022 (in thousands).

	Three Months Ended				Six Months Ended
	June 30, 2023		June 30, 2022		June 30, 2023		June 30, 2022
Income tax expense	$	—	$	6	$	225	$	15

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax reporting purposes at the TRS level. As of June 30, 2023 and December 31, 2022, the Company recorded a deferred tax asset of approximately $30.7 million and $30.2 million, respectively, relating to net operating loss carryforwards, capital loss carryforwards, and basis differences of certain investments held within TRSs. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible. The Company concluded it is more likely than not the deferred tax asset will not be realized and established a full valuation allowance as of June 30, 2023 and December 31, 2022.

Uncertain Income Tax Positions

Based on its analysis of any potential uncertain income tax positions, the Company concluded it did not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of June 30, 2023 and December 31, 2022. The Company’s federal income tax returns for the last three tax years are open to examination by the Internal Revenue Service. There are no ongoing U.S. federal, state or local tax examinations related to the Company. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes.

As previously announced, on August 8, 2023, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Western Asset Mortgage Capital Corporation, a Delaware corporation ("WMC"), AGMIT Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Merger Sub"), and, solely for the purposes set forth in the Merger Agreement, the Manager. Pursuant to, and subject to the terms and conditions set forth in the Merger Agreement, WMC will merge with and into Merger Sub, with Merger Sub surviving (the "Merger").

The execution by the Company, Merger Sub, WMC and the Manager of the Merger Agreement was concurrent with the termination by WMC of the Agreement and Plan of Merger, dated as of June 27, 2023, by and among WMC, Maverick Merger Sub, LLC and Terra Property Trust, Inc. (the "TPT Merger Agreement"), on August 8, 2023, in accordance with its terms. On August 8, 2023, concurrently with the termination by WMC of the TPT Merger Agreement, the Company, on behalf of WMC, paid to Terra Property Trust, Inc. a termination fee of $3.0 million as required by the TPT Merger Agreement (the "TPT Termination Fee").

Under the terms of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each outstanding share of WMC common stock will be converted into the right to receive the following (the "Per Share Merger Consideration"): (i) 1.50 shares, or 9.2 million shares in aggregate, of the Company's common stock pursuant to a fixed exchange ratio (subject to adjustment for transaction expenses); and (ii) the per share portion of a cash payment from the Manager equal to the lesser of $7.0 million or approximately 9.9% of the aggregate Per Share Merger Consideration (any difference between $7.0 million and the approximately 9.9% cap will be used to benefit the combined company post-closing by offsetting reimbursable expenses that would otherwise be payable to the Manager). Additionally, the Manager, which will be the manager of the combined

company, will waive $2.4 million of management fees owed to it in the first year post-closing. Cash will be paid in lieu of any fractional shares of the Company's common stock that would otherwise have been received as a result of the Merger. For purposes of the transaction expenses adjustment, WMC's transaction expenses exclude (i) a $7.0 million termination fee payable by WMC to its existing manager in connection with the termination of the existing WMC management agreement, (ii) accrued but unpaid management fees and unreimbursed expenses owed to WMC's manager, (iii) transfer taxes, (iv) the costs of a D&O tail policy, and (v) the TPT Termination Fee. Additionally, at the Effective Time, M. Christian Mitchell and Lisa G. Quateman (together, the "WMC Director Designees"), each an independent director currently serving on WMC's board of directors, will be appointed to the Company's Board of Directors. The Company has further agreed to nominate the WMC Director Designees to the Company's Board of Directors at its next annual stockholder meeting following the Effective Time.

The Merger is expected to close in the fourth quarter of 2023, subject to the respective approvals by the Company's stockholders and WMC's stockholders and other customary closing conditions set forth in the Merger Agreement.

In connection with the proposed Merger with WMC, the Company and the Manager entered into an amendment (the "MITT Management Agreement Amendment") to the management agreement, pursuant to which (i) 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 occurs, and (ii) the Manager will waive its right to seek reimbursement from the Company for any expenses otherwise reimbursable by the Company under the management agreement in an amount equal to the excess, if any, of $7.0 million over the aggregate cash portion of the Per Share Merger Consideration paid by the Manager to the holders of WMC common stock in the Merger. The amendment will become effective automatically upon the closing of the Merger, and will have no force and effect if the Merger does not close.

Our company

We are 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. Our objective is to provide attractive risk-adjusted returns to our stockholders over the long-term, primarily through dividends and capital appreciation.

We focus our investment activities primarily on acquiring and securitizing newly-originated residential mortgage loans within the non-agency segment of the housing market. We obtain our assets through Arc Home, LLC ("Arc Home"), our residential mortgage loan originator in which we own an approximate 44.6% interest, and through other third-party origination partners. We finance our acquired loans through various financing lines on a short-term basis and utilize Angelo Gordon's proprietary securitization platform to secure long-term, non-recourse, non-mark-to-market financing as market conditions permit. Through our ownership in Arc Home, we also have exposure to mortgage banking activities. Arc Home is a multi-channel licensed mortgage originator and servicer primarily engaged in the business of originating and selling residential mortgage loans while retaining the mortgage servicing rights associated with certain loans that it originates.

Our investment portfolio (which excludes our ownership in Arc Home) includes Residential Investments and Agency RMBS. Currently, our Residential Investments primarily consist of newly originated Non-Agency Loans and Agency-Eligible Loans, which we refer to as our target assets. In addition, we may also invest in other types of residential mortgage loans and other mortgage related assets. As of June 30, 2023, the Company's investment portfolio consisted 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, we include these loans within our Non-Agency securitizations.
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 Residential Mortgage-Backed Securities ("RMBS")(2)	•Non-Agency RMBS represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. The mortgage loan collateral consists of either Non-Agency Loans or Agency-Eligible Loans.
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.

(1)These investments are included in the "Securitized residential mortgage loans, at fair value," "Securitized residential mortgage loans held for sale, at fair value," "Residential mortgage loans, at fair value," and "Residential mortgage loans held for sale, 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.

41

Our primary sources of income are net interest income from our investment portfolio, changes in the fair value of our investments, and income from our investment in Arc Home. Net interest income consists of the interest income we earn on investments less the interest expense we incur on borrowed funds and any costs related to hedging. Income from our investment in Arc Home is generated through its mortgage banking activities which represents the origination and subsequent sale of residential mortgage loans and servicing income sourced from its portfolio of mortgage servicing rights.

We were incorporated in Maryland on March 1, 2011 and commenced operations in July 2011. We conduct our operations to qualify and be taxed as a REIT for U.S. federal income tax purposes. Accordingly, we generally will not be subject to U.S. federal income taxes on our taxable income that we distribute to our stockholders as long as we maintain our intended qualification as a REIT, with the exception of business conducted in our domestic taxable REIT subsidiaries ("TRSs") which are subject to corporate income tax. We also operate our business in a manner that permits us to maintain our exemption from registration under the Investment Company Act.

Proposed Western Asset Mortgage Capital Corporation Merger

As previously announced, on August 8, 2023, the Company entered into an Agreement and Plan of Merger (the "Merger Agreement") with Western Asset Mortgage Capital Corporation, a Delaware corporation ("WMC"), AGMIT Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company ("Merger Sub"), and, solely for the purposes set forth in the Merger Agreement, our Manager. Pursuant to, and subject to the terms and conditions set forth in the Merger Agreement, WMC will merge with and into Merger Sub, with Merger Sub surviving (the "Merger").

The execution by the Company, Merger Sub, WMC and our Manager of the Merger Agreement was concurrent with the termination by WMC of the Agreement and Plan of Merger, dated as of June 27, 2023, by and among WMC, Maverick Merger Sub, LLC and Terra Property Trust, Inc. (the "TPT Merger Agreement"), on August 8, 2023, in accordance with its terms. On August 8, 2023, concurrently with the termination by WMC of the TPT Merger Agreement, we, on behalf of WMC, paid to Terra Property Trust, Inc. a termination fee of $3.0 million as required by the TPT Merger Agreement (the "TPT Termination Fee").

Under the terms of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each outstanding share of WMC common stock will be converted into the right to receive the following (the "Per Share Merger Consideration"): (i) 1.50 shares, or 9.2 million shares in aggregate, of the Company's common stock pursuant to a fixed exchange ratio (subject to adjustment for transaction expenses); and (ii) the per share portion of a cash payment from our Manager equal to the lesser of $7.0 million or approximately 9.9% of the aggregate Per Share Merger Consideration (any difference between $7.0 million and the approximately 9.9% cap will be used to benefit the combined company post-closing by offsetting reimbursable expenses that would otherwise be payable to our Manager). Additionally, our Manager, which will be the manager of the combined company, will waive $2.4 million of management fees owed to it in the first year post-closing. Cash will be paid in lieu of any fractional shares of the Company's common stock that would otherwise have been received as a result of the Merger. For purposes of the transaction expenses adjustment, WMC's transaction expenses exclude (i) a $7.0 million termination fee payable by WMC to its existing manager in connection with the termination of the existing WMC management agreement, (ii) accrued but unpaid management fees and unreimbursed expenses owed to WMC's manager, (iii) transfer taxes, (iv) the costs of a D&O tail policy and (v) the TPT Termination Fee. Additionally, at the Effective Time, M. Christian Mitchell and Lisa G. Quateman (together, the "WMC Director Designees"), each an independent director currently serving on WMC's board of directors, will be appointed to our Board of Directors. We have further agreed to nominate the WMC Director Designees to our Board of Directors at the next annual stockholder meeting following the Effective Time.

The Merger is expected to close in the fourth quarter of 2023, subject to the respective approvals by our stockholders and WMC's stockholders and other customary closing conditions set forth in the Merger Agreement.

Our Manager and Angelo Gordon

We are externally managed by our Manager, a subsidiary of Angelo Gordon. Pursuant to the terms of our management agreement, our Manager provides us with our management team, including our officers, along with appropriate support personnel. All of our officers are employees of Angelo Gordon or its affiliates. We do not have any employees. Our Manager is at all times subject to the supervision and oversight of our Board of Directors and has only such functions and authority as our Board of Directors delegates to it. Our Manager has delegated to Angelo Gordon the overall responsibility with respect to our Manager’s day-to-day duties and obligations arising under our management agreement.

42

Through our relationship with our Manager, we benefit from the expertise and relationships that Angelo Gordon has established which provides us with resources to generate attractive risk-adjusted returns for our stockholders. Our management has significant experience in the mortgage industry and expertise in structured credit investments. We are able to leverage our Manager, along with our ownership interest in Arc Home, a vertically integrated origination platform, to access investment opportunities in the non-agency residential mortgage loan market. This strategic advantage has enabled us to grow our investment portfolio and remain active in the securitization markets, utilizing Angelo Gordon's proprietary securitization platform to deliver non-agency investments to a diverse mix of investors.

On May 15, 2023, Angelo Gordon announced that it and certain of its affiliated entities entered into a transaction agreement (the "Transaction Agreement") with TPG Inc. ("TPG") and certain of its affiliated entities pursuant to which TPG has agreed to acquire Angelo Gordon on the terms and subject to the conditions set forth in the Transaction Agreement (the "TPG Transaction"). Following the TPG Transaction, Angelo Gordon, including our Manager, will be indirect subsidiaries of TPG. Our investment strategy and team remains unchanged, and the TPG Transaction is not expected to have a material impact on our operations.

The TPG Transaction is expected to close in the fourth quarter of 2023, subject to customary closing conditions, including Hart-Scott-Rodino Act filings, international regulatory approvals, and other client and third-party consents. Pursuant to the management agreement with our Manager, the closing of the TPG Transaction will result in an assignment of the management agreement. On July 31, 2023, our independent directors unanimously consented to such assignment. There will be no changes to the management agreement in connection with the TPG Transaction and the assignment of the management agreement will become effective upon the closing of the TPG Transaction.

Market Conditions

Financial markets continued to manage volatility during the second quarter of 2023 due to multiple factors including the impacts of inflation, the path of monetary policy and interest rates, the regional banking crisis, the U.S. debt ceiling, market uncertainty from the ongoing conflict in Ukraine and other geopolitical risks, and the lingering impact of the COVID-19 pandemic. While the regional banking crisis appears to have been contained, banks that failed were taken over by the FDIC and their assets continue to be liquidated into the third quarter of 2023. In early June 2023, Congress approved legislation that suspended the U.S. debt ceiling until 2025, and risk sentiment in the markets began to improve. However, benchmark interest rates continued to increase during the second quarter further exacerbating the inverted yield curve as the Federal Reserve increased the Fed Funds rate by 25 basis point in May and again in July in an effort to slow inflation.

Credit spreads for the securitized residential debt sector tightened during the quarter, having benefited from fixed income fund inflows and an improvement in the risk sentiment of the broader market. Trends in credit spreads on credit risk transfer ("CRT") assets are generally utilized by market participants as a proxy for evaluating credit related assets given the observability of transactions. CRT spreads showed significant improvement during the second quarter 2023, with subordinate credit tranches tightening anywhere from 50 to 350 basis points depending on positioning in the capital structure. In addition, senior Non-QM mortgage spreads tightened by approximately 15 basis points, and legacy RMBS spreads were 30 to 40 basis points tighter during the second quarter 2023. As spreads remain wider than February 2022 levels, a material amount of capacity for additional tightening exists for RMBS.

RMBS issuance fell by approximately 19% to $15 billion in the second quarter 2023, compared to $18.6 billion in the first quarter 2023, with Non-QM comprising a large share of the decline. Issuance fell sharply amid limited origination activity and higher securitization coupons. Year to date issuance in 2023 was $33.5 billion, decreasing approximately 66% from 2022 levels. Various reports from bank research departments expect issuance for the full year 2023 to be between $60 billion and $90 billion, down from $127 billion in 2022 and $213 billion in 2021.

After posting seven consecutive months of declines through February 2023, national home prices rose by 1.3% in each of March and April 2023, the latest data available. With these increases through April 2023, home prices are over 2% higher year to date 2023 and only 2.4% below their June 2022 peak.

Mortgage rates ended the quarter at approximately 6.7%, which was less than the Q4 2022 peaks of over 7% and slightly higher than rates of 6.2% as of Q1 2023. Amid persistently higher prevailing mortgage rates, home prices and activity have exceeded expectations with new home sales being a driving force, rising from 636 thousand in December 2022 to 763 thousand in May 2023. On the other hand, existing home sales were hampered by persistently limited listings. Total listings were 1.08 million in May 2023, which compares to 1.15 million in May 2022 and 1.91 million in 2019.

43

While homeownership affordability is near all-time lows, housing supply continues to be constrained and demand for housing remains evident as borrowers reset in a higher-rate environment.

Presentation of investment, financing and hedging activities

In the "Investment activities," "Financing activities," "Hedging activities," and "Liquidity and capital resources" sections of this Item 2, we present information on our investment portfolio and the related financing arrangements inclusive of unconsolidated ownership interests in affiliates that are accounted for under GAAP using the equity method. Our investment portfolio excludes our investment in Arc Home.

Our investment portfolio and the related financing arrangements are presented along with a reconciliation to GAAP. This presentation of our investment portfolio is consistent with how our management team 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 Note 10 to the "Notes to Consolidated Financial Statements (unaudited)" for a discussion of investments in debt and equity of affiliates. See below for further terms used when describing our investment portfolio.

•Our "Investment portfolio" includes our Residential Investments and Agency RMBS, inclusive of TBAs.

•Our "Residential Investments" refer to our residential mortgage loans and Non-Agency RMBS.

◦"Residential mortgage loans" or "Loans" refer to our Non-Agency Loans, Agency-Eligible Loans, and Re/Non-Performing Loans (exclusive of retained tranches from unconsolidated securitizations) and Land Related Financing.

◦"Non-Agency RMBS" refer to the retained tranches from unconsolidated securitizations of Non-Agency Loans and Re/Non-Performing Loans, as well as RMBS collateralized by Non-Agency Loans and Agency-Eligible Loans.

•"Real estate securities" refers to our Non-Agency RMBS and Agency RMBS, inclusive of TBAs.

Book value and Adjusted book value per share

The below table details book value and adjusted book value per common share. Per share amounts for book value are calculated using all outstanding common shares in accordance with GAAP as of quarter-end.

	June 30, 2023		December 31, 2022
Book value per common share	$	11.89	$	11.39
Net proceeds of preferred stock less liquidation preference of preferred stock per common share (1)	(0.37)		(0.36)
Adjusted book value per common share	$	11.52	$	11.03

(1)Book value per common share is calculated using stockholders’ equity less net proceeds of $220.5 million on our issued and outstanding preferred stock as the numerator. Adjusted book value per common share is calculated using stockholders’ equity less the liquidation preference of $228.0 million on our issued and outstanding preferred stock as the numerator.

Results of Operations

Our operating results can be affected by a number of factors and primarily depend on the size and composition of our investment portfolio, the level of our net interest income, the fair value of our assets and the supply of, and demand for, our investments in residential mortgage loans in the marketplace, among other things, which can be impacted by unanticipated credit events, such as defaults, liquidations or delinquencies, experienced by borrowers whose residential mortgage loans are included in our investment portfolio and other unanticipated events in our markets. Our primary source of net income or loss available to common stockholders is our net interest income, inclusive of our cost or benefit of hedging, which represents the difference between the interest earned on our investment portfolio and the costs of financing and economic hedges in place on our investment portfolio, as well as any income or losses from our equity investments in affiliates.

Interest income

Interest income is calculated using the effective interest method for our GAAP investment portfolio.

Interest income increased from the three months ended June 30, 2022 to the three months ended June 30, 2023 due to an increase in the size of our portfolio resulting from purchases of Non-Agency Loans and Agency-Eligible Loans during the period, as well as an increase in the weighted average yield. The following table presents a summary of the weighted average amortized cost and the weighted average yield on our GAAP investment portfolio for the three months ended June 30, 2023 and 2022 ($ in millions).

Interest expense

Interest expense is calculated based on the actual financing rate and the outstanding financing balance, inclusive of our financing arrangements and securitized debt, on our GAAP investment portfolio. 

Interest expense increased from the three months ended June 30, 2022 to the three months ended June 30, 2023 due to an increase in the weighted average financing rate during the period resulting from increased interest rates and an increase in the amount of financing on our GAAP investment portfolio primarily resulting from the issuance of securitized debt. The following table presents a summary of the weighted average financing balance and the weighted average financing rate on our GAAP investment portfolio for the three months ended June 30, 2023 and 2022 ($ in millions).

Net interest component of interest rate swaps

Net interest component of interest rate swaps represents the net interest income received or expense paid on our interest rate swaps.

We recorded income on the net interest component of interest rate swaps during the three months ended June 30, 2023 as a result of our swap portfolio being in a net receive position during the period, compared with an expense for the three months ended June 30, 2022 as a result of our swap portfolio being in a net pay position during the period. The following table presents a summary of our interest rate swap portfolio as of June 30, 2023 and 2022 ($ in millions).

Earnings Available for Distribution

One of our objectives is to generate net income from net interest margin on the portfolio, and management uses Earnings Available for Distribution ("EAD"), as one of several metrics, to help measure our performance against this objective. Management believes that this non-GAAP measure, when considered with our GAAP financial statements, provides supplemental information useful for investors to help evaluate our financial performance. However, management also believes that our definition of EAD has important limitations as it does not include certain earnings or losses our management team considers in evaluating our financial performance. Our presentation of EAD 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, Net Income/(loss) available to common stockholders or Net income/(loss) per diluted common share calculated in accordance with GAAP. Our GAAP financial results and the reconciliations from these results should be carefully evaluated.

We define EAD, a non-GAAP financial measure, as Net Income/(loss) available to common stockholders excluding (i) (a) unrealized gains/(losses) on loans, real estate securities, derivatives and other investments, inclusive of our investment in AG

53

Arc, and (b) net realized gains/(losses) on the sale or termination of such instruments, (ii) any transaction related expenses incurred in connection with the acquisition, disposition, or securitization of our investments, (iii) accrued deal-related performance fees payable to third party operators to the extent the primary component of the accrual relates to items that are excluded from EAD, such as unrealized and realized gains/(losses), (iv) realized and unrealized changes in the fair value of Arc Home's net mortgage servicing rights and the derivatives intended to offset changes in the fair value of those net mortgage servicing rights, (v) deferred taxes recognized at our taxable REIT subsidiaries, if any, and (vi) any gains/(losses) associated with exchange transactions on our common and preferred stock. Items (i) through (vi) above include any amount related to those items held in affiliated entities. Management considers the transaction related expenses referenced in (ii) above to be similar to realized losses incurred at the acquisition, disposition, or securitization of an asset and does not view them as being part of its core operations. Management views the exclusion described in (iv) above to be consistent with how it calculates EAD on the remainder of its portfolio. Management excludes all deferred taxes because it believes deferred taxes are not representative of current operations. EAD includes the net interest income and other income earned on our investments on a yield adjusted basis, including TBA dollar roll income/(loss) or any other investment activity that may earn or pay net interest or its economic equivalent.

A reconciliation of "Net Income/(loss) available to common stockholders" to EAD for the three and six months ended June 30, 2023 and 2022 is set forth below (in thousands, except per share data).

Additionally, for the three months ended June 30, 2023 and 2022, $0.0 million or $0.00 per share and $(2.7) million or $(0.12) per share, respectively; and for the six months ended June 30, 2023 and 2022, $0.2 million or $0.01 per share and $(5.2) million or $(0.22) per share, respectively, of unrealized changes in the fair value of our investment in Arc Home were excluded from EAD.

(3)EAD recognized by AG Arc does not include our portion of gains recorded by Arc Home in connection with the sale of residential mortgage loans to us. For the three months ended June 30, 2023 and 2022, we eliminated $0.3 million or $0.02 per share and $1.8 million or $0.07 per share, respectively. For the six months ended June 30, 2023 and 2022, we eliminated $0.3 million or $0.02 per share and $4.1 million or $0.17 per share, respectively, of intra-entity profits recognized by Arc Home, and also decreased the cost basis of the underlying loans we purchased by the same amount. Refer to Note 10 to the "Notes to Consolidated Financial Statements (unaudited)" for more information on this accounting policy.

Investment activities

Investment activities

We aim to allocate capital to investment opportunities with attractive risk/return profiles in our target asset classes. Our investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans. We finance our acquired loans through various financing lines on a short-term basis and securitize the loans to obtain long-term, non-recourse, non-mark-to-market financing as market conditions permit. We may also invest in Agency RMBS to utilize excess liquidity. Our investment and capital allocation decisions depend on prevailing market conditions and compliance with Investment Company Act and REIT tests, among other factors, and may change over time in response to opportunities available in different economic and capital market environments. As a result, in reacting to market conditions and taking into account a variety of other factors, including liquidity, duration, and interest rate expectations, the mix of our assets changes over time as we deploy capital. We actively evaluate our investments based on factors including, among others, the characteristics of the underlying collateral, geography, expected return, expected future prepayment trends, supply of and demand for our investments, costs of financing, costs of hedging, expected future interest rate volatility, and the overall shape of the U.S. Treasury and interest rate swap yield curves.

Net interest margin and leverage ratio

Net interest margin and leverage ratio are metrics that management believes should be considered when evaluating the performance of our investment portfolio.

GAAP net interest margin and non-GAAP net interest margin, a non-GAAP financial measure, are calculated by subtracting the weighted average cost of funds from the weighted average yield for our GAAP investment portfolio and our investment portfolio, respectively. The weighted average yield represents an effective interest rate on our cost basis, which utilizes all estimates of future cash flows and adjusts for actual prepayment and cash flow activity as of quarter-end. The calculation of weighted average yield is weighted on fair value at quarter-end. The weighted average cost of funds is the sum of the weighted average funding costs on total financing arrangements outstanding at quarter-end, including all non-recourse financing arrangements, and our weighted average hedging cost or benefit, which is the weighted average of the net pay or receive rates on our interest rate swaps. GAAP and non-GAAP cost of funds are weighted by the outstanding financing arrangements on our GAAP investment portfolio and our investment portfolio, respectively, and the fair value of securitized debt at quarter-end.

Our leverage ratio is determined by our portfolio mix as well as many additional factors, including the liquidity of our portfolio, the availability and price of our financing, the available capacity to finance our assets, and anticipated regulatory developments. See the "Financing activities" section below for more detail on our leverage ratio.

Securitized Non-Agency Loans

As noted above, our investment activities primarily include acquiring and securitizing newly-originated residential mortgage loans. These securitization trusts ("Non-Agency VIEs") are collateralized by Non-Agency and Agency-Eligible Loans.

In each securitization transaction, we transfer a pool of loans to a wholly-owned subsidiary and the loans are deposited into a newly created securitization trust. The securitization trust issues various classes of mortgage pass-through certificates backed by the cash flows from the underlying residential mortgage loans (the "Certificates"). When we sponsor a residential mortgage loan securitization, we are generally required to retain at least 5% of the fair value of the Certificates issued in the securitization ("Risk Retention Rules"). We can retain either an "eligible vertical interest" (which consists of at least 5% of each class of securities issued in the securitization), an "eligible horizontal residual interest" (which is the most subordinate class of securities with a fair value of at least 5% of the aggregate credit risk) or a combination of both totaling 5% (the "Required Credit Risk"). In order to comply with the Risk Retention Rules in each securitization transaction, we generally purchase the most subordinated classes of Certificates and the excess cash flow Certificates. We also purchase the Certificates entitled to excess servicing fees and may purchase other Certificates issued by the securitization trust, while typically selling the senior classes of Certificates to unrelated third parties.

If we are determined to be the primary beneficiary of these securitization transactions, we consolidate the respective VIE created to facilitate the transaction and record "Securitized residential mortgage loans" and "Securitized debt" on the consolidated balance sheets in accordance with U.S. GAAP. However, as noted above, our equity at risk represents certain Certificates from each securitization which we retain.

(1)Interest Only have no principal balances and bear interest based on a notional balance. The notional balance is used solely to determine interest distributions on the interest only classes of securities. As of June 30, 2023 and December 31, 2022, the Securitized debt in Non-Agency VIEs line item includes interest only classes with notional balances of $137.9 million and $144.3 million, respectively. As of June 30, 2023 and December 31, 2022, the notional balance on Interest Only / Excess Servicing Bonds was $8.2 billion and $8.0 billion, respectively.

(2)Maximum loss exposure from our involvement with VIEs pertains to the fair value of the Certificates retained from the VIEs. We have no obligation to provide any other explicit or implicit support to the securitization trusts.

(3)As of June 30, 2023 and December 31, 2022, our equity at risk included bonds with a fair value of $228.0 million and $215.1 million, respectively, held in order to comply with Risk Retention Rules. We are generally required to hold the Required Credit Risk until the later of (i) the fifth anniversary of the securitization closing date and (ii) the date on which the aggregate unpaid principal balance of the mortgage loans has been reduced to 25% of the aggregate unpaid principal balance of the mortgage loans as of the securitization closing date, but no longer than the seventh anniversary of the closing date.

(4)As of June 30, 2023 and December 31, 2022, a portion of our equity at risk included bonds exposed to the first loss of the securitization with a fair value of $80.5 million and $84.7 million, respectively.

(5)Excludes net other asset/(liabilities) held within the VIEs of $4.4 million and $4.4 million as of June 30, 2023 and December 31, 2022, respectively.

(6)As the sponsor and depositor of each securitization, we may purchase all of the outstanding Certificates (an "Optional Redemption") following the earlier of (1) an applicable anniversary date (typically two or three years) of the respective securitization or (2) the date at which the unpaid principal balance of the applicable collateral has declined below a certain percentage (typically 10% to 30%) of the principal balance originally contributed to the securitization. As of June 30, 2023 and December 31, 2022, there were no securitizations which met the criteria for an Optional Redemption.

(1)Represents the weighted average monthly CPRs published during the period for our in-place portfolio.

Financing activities

We use leverage to finance the purchase of our investment portfolio. Our leverage has primarily been in the form of repurchase agreements and similar financing arrangements (which we refer to collectively as financing arrangements), and securitized debt.

Repurchase agreements involve the sale and a simultaneous agreement to repurchase the transferred assets or similar assets at a future date. The amount borrowed generally is equal to the fair value of the assets pledged less an agreed-upon discount, referred to as a "haircut." The size of the haircut reflects the perceived risk associated with the pledged asset. Haircuts may change as our financing arrangements mature or roll and are sensitive to governmental regulations. Interest rates for our financing arrangements are determined based on prevailing rates (typically a spread over a base rate) corresponding to the terms of the borrowings, and interest is paid on a monthly basis or, for shorter term arrangements, at the end of the term. Repurchase agreements typically have a term of up to one year for loans and a term of 30 to 90 days for securities. Repurchase agreements are generally mark-to-market with respect to margin calls and recourse to us. We had outstanding financing arrangements with six counterparties as of June 30, 2023 and December 31, 2022.

Our financing arrangements generally include customary representations, warranties, and covenants, but may also contain more restrictive supplemental terms and conditions. Although specific to each financing arrangement, typical supplemental terms include requirements of minimum equity and liquidity, leverage ratios, and performance triggers. In addition, some of the financing arrangements contain cross default features, whereby default under an agreement with one lender simultaneously causes default under agreements with other lenders. To the extent that we fail to comply with the covenants contained in these financing arrangements or is otherwise found to be in default under the terms of such agreements, the counterparty has the right to accelerate amounts due under the associated agreement. As of June 30, 2023, we are in compliance with all of our financial covenants.

We also use securitized debt to finance our loan portfolio. Securitized debt is generally non-mark-to-market with respect to margin calls and non-recourse to us.

Leverage

We use leverage to increase potential returns to our stockholders and to fund the acquisition of our investment portfolio. Our financing strategy is designed to increase the size of our investment portfolio by borrowing against the fair value of the assets in our portfolio. When acquiring residential mortgage loans and other assets, we finance our investments using repurchase agreements or similar financing arrangements, which we refer to collectively as "financing arrangements." Upon accumulating a targeted amount of residential mortgage loans, we finance these assets utilizing long-term, non-recourse, non-mark-to-market securitizations as market conditions permit. Financing arrangements are generally recourse to the Company whereas securitized debt used to finance our Residential Mortgage Loan VIEs is generally non-recourse to the Company. In addition to disclosing GAAP leverage, we also disclose Economic Leverage, which excludes non-recourse financing. Management believes that this non-GAAP measure, when considered with our GAAP financial statements, provides supplemental information useful for investors to help evaluate our use of leverage and the related risk associated with our leverage profile. Our presentation of Economic Leverage 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, GAAP leverage calculated in accordance with GAAP. Our GAAP financial results and the reconciliations from these results should be carefully evaluated.

We define GAAP leverage as the sum of (1) GAAP Securitized debt, at fair value, (2) our GAAP Financing arrangements, net of any restricted cash posted on such financing arrangements, and (3) the amount payable on purchases that have not yet settled less the financing remaining on sales that have not yet settled. We define Economic Leverage, a non-GAAP metric, as the sum of: (i) our GAAP leverage, exclusive of any fully non-recourse financing arrangements, (ii) financing arrangements held through affiliated entities, net of any restricted cash posted on such financing arrangements, exclusive of any financing utilized through AG Arc, any adjustment related to unsettled trades as described in (2) in the previous sentence, and any non-recourse financing arrangements and (iii) our net TBA position (at cost), if any.

The calculations in the tables below divide GAAP leverage and Economic Leverage by our GAAP stockholders’ equity to derive our leverage ratios. The following tables present a reconciliation of our Economic Leverage ratio to GAAP Leverage ($ in thousands).

Hedging activities

Subject to maintaining our qualification as a REIT and our Investment Company Act exemption, to the extent leverage is deployed, we may utilize derivative instruments in an effort to hedge the interest rate risk associated with the financing of our portfolio. Specifically, we may seek to hedge our exposure to potential interest rate mismatches between the interest we earn on our investments and our borrowing costs caused by fluctuations in short-term interest rates. We may utilize interest rate swaps, swaption agreements, and other financial instruments such as short positions in to-be-announced securities. In utilizing leverage and interest rate derivatives, our objectives are to improve risk-adjusted returns and, where possible, to lock in, on a long-term basis, a spread between the yield on our assets and the costs of our financing and hedging. Derivatives have not been designated as hedging instruments for GAAP. See Note 7 in the "Notes to Consolidated Financial Statements (unaudited)" for more information.

Dividends

Federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT ordinary taxable income, without regard to the deduction for dividends paid and excluding net capital gains and that it pay tax at regular corporate rates to the extent that it annually distributes less than 100% of its net taxable income. Before we pay any dividend, whether for U.S. federal income tax purposes or otherwise, we must first meet both our operating requirements and debt service on our financing arrangements and other debt payable. If our cash available for distribution is less than our net taxable income, we could be required to sell assets or borrow funds to make required cash distributions or we may make a portion of the required distribution in the form of a taxable stock distribution or distribution of debt securities.

As described above, our distribution requirements are based on taxable income rather than GAAP net income. Differences between taxable income and GAAP net income include (i) unrealized gains and losses associated with investment and derivative portfolios which 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 premiums and discounts paid on investments, (iii) the timing and amount of deductions related to stock-based compensation, (iv) temporary differences related to the recognition of realized gains and losses on sold investments and certain terminated derivatives, (v) taxes, (vi) methods of depreciation and (vii) differences between GAAP income or losses in our TRSs’ and taxable income resulting from dividend distributions to the REIT from our TRSs'. Undistributed taxable income is based on current estimates and is not finalized until we file our annual

63

tax return for that tax year, typically in October of the following year. We did not have any undistributed taxable income as of June 30, 2023.

The following table details our common stock dividends declared during the six months ended June 30, 2023 and 2022.

Liquidity and capital resources

Our liquidity determines our ability to meet our cash obligations, including distributions to our stockholders, payment of our expenses, financing our investments and satisfying other general business needs.

Our principal sources of cash consist of borrowings under financing arrangements, principal and interest payments we receive on our investment portfolio, cash generated from our operating results, and proceeds from capital market transactions. We typically use cash to repay principal and interest on our financing arrangements, to purchase loans, real estate securities, and other real estate related assets, to make dividend payments on our capital stock, to repurchase our capital stock, and to fund our operations. We may also generate liquidity when restricted cash that was pledged as collateral for clearing and executing trades, derivatives, and financing arrangements becomes unrestricted when the related collateral requirements are exceeded or at the maturity of the derivative or financing arrangement. Refer to "—Margin requirements" below discussing instances where we may use liquidity to meet margin requirements. At June 30, 2023, we had $80.3 million of liquidity, all of which was cash and cash equivalents. Refer to the "Contractual obligations" section of this Item 2 for additional obligations that could impact our liquidity.

Margin requirements

The fair value of our loans and real estate securities fluctuate according to market conditions. When the fair value of the assets pledged as collateral to secure a financing arrangement decreases to the point where the difference between the collateral fair value and the financing arrangement amount is less than the haircut, our lenders may issue a "margin call," which requires us to post additional collateral to the lender in the form of additional assets or cash. Under our repurchase facilities, our lenders have full discretion to determine the fair value of the securities we pledge to them. Our lenders typically value assets based on recent transactions in the market. Lenders also issue margin calls as the published current principal balance factors change on the pool of mortgages underlying the securities pledged as collateral when scheduled and unscheduled paydowns are announced monthly. We experience margin calls in the ordinary course of our business. In seeking to effectively manage the margin

64

requirements established by our lenders, we maintain a position of cash and, when owned, unpledged Agency RMBS. We refer to this position as our "liquidity." The level of liquidity we have available to meet margin calls is directly affected by our leverage levels, our haircuts and the price changes on our assets. Typically, if interest rates increase or if credit spreads widen, then the prices of our collateral (and our unpledged assets that constitute our liquidity) will decline, we will experience margin calls, and we will need to use our liquidity to meet the margin calls. There can be no assurance that we will maintain sufficient levels of liquidity to meet any margin calls. If our haircuts increase, our liquidity will proportionately decrease. In addition, if we increase our borrowings, our liquidity will decrease by the amount of additional haircut on the increased level of indebtedness. We intend to maintain a level of liquidity in relation to our assets that enables us to meet reasonably anticipated margin calls but that also allows us to be substantially invested in the residential mortgage market. We may misjudge the appropriate amount of our liquidity by maintaining excessive liquidity, which would lower our investment returns, or by maintaining insufficient liquidity, which may force us to liquidate assets into potentially unfavorable market conditions and harm our results of operations and financial condition. Further, an unexpected rise in interest rates and a corresponding fall in the fair value of our securities may also force us to liquidate assets under difficult market conditions, thereby harming our results of operations and financial condition, in an effort to maintain sufficient liquidity to meet increased margin calls.

Similar to the margin calls that we receive on our borrowing agreements, we may also receive margin calls on our derivative instruments when their fair value declines. This typically occurs when prevailing market rates change adversely, with the severity of the change also dependent on the terms of the derivatives involved. We may also receive margin calls on our derivatives based on the implied volatility of interest rates. Our posting of collateral with our counterparties can be done in cash or assets, and is generally bilateral, which means that if the fair value of our interest rate hedges increases, our counterparty will be required to post collateral with us. Refer to the "Liquidity risk – derivatives" section of Item 3 below for a further discussion on margin.

Cash flows

The below details changes to our cash, cash equivalents, and restricted cash for the six months ended June 30, 2023 and 2022 ($ in thousands).

	Six Months Ended
	June 30, 2023		June 30, 2022		Change
Cash and cash equivalents and restricted cash, Beginning of Period	$	98,803	$	100,229	$	(1,426)
Net cash provided by (used in) operating activities (1)	15,093		12,898		2,195
Net cash provided by (used in) investing activities (2)	(156,759)		(761,877)		605,118
Net cash provided by (used in) financing activities (3)	148,227		789,400		(641,173)
Net change in cash and cash equivalents and restricted cash	6,561		40,421		(33,860)
Cash and cash equivalents and restricted cash, End of Period	$	105,364	$	140,650	$	(35,286)

(1)Cash provided by operating activities is primarily attributable to net interest income less operating expenses for the six months ended June 30, 2023.

(2)Cash used in investing activities for the six months ended June 30, 2023 was primarily attributable to purchases of investments, offset by sales of investments and principal repayments on investments.

(3)Cash provided by financing activities for the six months ended June 30, 2023 was primarily attributable to the issuance of securitized debt and net borrowings under financing arrangements, offset by principal repayments on securitized debt, dividend payments, and common share repurchases.

Stock repurchase programs

On November 3, 2015, our Board of Directors authorized a stock repurchase program (the "2015 Repurchase Program") to repurchase up to $25.0 million of our outstanding common stock. As of June 30, 2022, the $25.0 million maximum repurchase amount authorized under the 2015 Repurchase Program was fully utilized.

On August 3, 2022, our Board of Directors authorized a stock repurchase program (the "2022 Repurchase Program") to repurchase up to $15.0 million of our outstanding common stock on substantially the same terms as the 2015 Repurchase Program. The 2022 Repurchase Program does not have an expiration date and permits us to repurchase our shares through various methods, including open market repurchases, privately negotiated block transactions and Rule 10b5-1 plans. We may repurchase shares of our common stock from time to time in compliance with SEC regulations and other legal requirements.

65

The extent to which we repurchase our shares, and the timing, manner, price, and amount of any such repurchases, will depend upon a variety of factors including market conditions and other corporate considerations as determined by management, as well as the limits of the 2022 Repurchase Program and our liquidity and business strategy. The 2022 Repurchase Program does not obligate us to acquire any particular amount of shares and may be modified or discontinued at any time. As of the date of this filing, approximately $1.5 million of common stock remained authorized for future share repurchases under the 2022 Repurchase Program. See Note 11 in the "Notes to Consolidated Financial Statements (unaudited)" for additional details on the shares repurchased under the 2022 Repurchase Program during the three and six months ended June 30, 2023.

On May 4, 2023, our Board of Directors authorized a stock repurchase program (the "2023 Repurchase Program") to repurchase up to $15.0 million of our outstanding common stock on substantially the same terms as the 2022 Repurchase Program. As of the date of this filing, the full $15.0 million authorized amount remains available for repurchase under the 2023 Repurchase Program. This authorization is in addition to the amount remaining under the 2022 Repurchase Program.

On February 22, 2021, our Board of Directors authorized a stock repurchase program (the "Preferred Repurchase Program") pursuant to which our Board of Directors granted a repurchase authorization to acquire shares of our Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock having an aggregate value of up to $20.0 million. No share repurchases under the Preferred Repurchase Program have been made since its authorization.

Shares of stock repurchased by us under any repurchase program, if any, will be cancelled and, until reissued by us, will be deemed to be authorized but unissued shares of its stock as required by Maryland law. The cost of the acquisition by us of shares of our own stock in excess of the aggregate par value of the shares first reduces additional paid-in capital, to the extent available, with any residual cost applied against retained earnings.

Equity distribution agreements

On May 5, 2017, we entered into an equity distribution agreement with each of Credit Suisse Securities (USA) LLC and JMP Securities LLC (collectively, the "Sales Agents"), which we refer to as the "Equity Distribution Agreements," pursuant to which we may sell up to $100.0 million aggregate offering price of shares of our common stock from time to time through the Sales Agents, under the Securities Act of 1933. We did not issue any shares of common stock under the Equity Distribution Agreements during the three and six months ended June 30, 2023. Since inception of the program, we have issued approximately 2.2 million shares of common stock under the Equity Distribution Agreements for gross proceeds of $48.3 million.

Forward-looking statements regarding liquidity

Based upon our current portfolio, leverage and available borrowing arrangements, we believe the net proceeds of our common equity offerings, preferred equity offerings, and private placements, combined with cash flow from operating activities, financing activities, and our available borrowing capacity will be sufficient to enable us to meet our anticipated liquidity requirements, including funding our investment activities, paying fees under our management agreement, funding our distributions to stockholders and paying general corporate expenses.

Contractual obligations

Management agreement

The management agreement, as amended, provides for payment to the Manager of a management fee, an incentive fee, and reimbursements of certain expenses incurred by the Manager or its affiliates on behalf of us. The closing of the TPG Transaction will result in an assignment of the management agreement. On July 31, 2023, our independent directors unanimously consented to such assignment. There will be no changes to the management agreement in connection with the TPG Transaction and the assignment of the management agreement will become effective upon the closing of the TPG Transaction.

In connection with the proposed Merger with WMC, we and our Manager entered into an amendment (the "MITT Management Agreement Amendment") to the management agreement, pursuant to which (i) 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 occurs, and (ii) the Manager will waive its right to seek reimbursement from us for any expenses otherwise reimbursable by us under the management agreement in an amount equal to the excess, if any, of $7.0 million over the aggregate cash portion of the Per Share Merger Consideration paid by the Manager to the holders of WMC common stock in

66

the Merger. The amendment will become effective automatically upon the closing of the Merger, and will have no force and effect if the Merger does not close.

Management fee

The management fee is calculated and payable quarterly in arrears in an amount equal to 1.50% of our Stockholders’ Equity, per annum. For purposes of calculating the management fee, "Stockholders’ Equity" means the sum of the net proceeds from any issuances of equity securities (including preferred securities) since inception (allocated on a pro rata daily basis for such issuances during the fiscal quarter of any such issuance, and excluding any future equity issuance to the Manager), plus our retained earnings at the end of such quarter (without taking into account any non-cash equity compensation expense or other non-cash items described below incurred in current or prior periods), less any amount that we pay for repurchases of our common stock, excluding any unrealized gains, losses or other non-cash items that have impacted stockholders’ equity as reported in our financial statements prepared in accordance with GAAP, regardless of whether such items are included in other comprehensive income or loss, or in net income, and excluding one-time events pursuant to changes in GAAP, and certain other non-cash charges after discussions between the Manager and our independent directors and after approval by a majority of our independent directors. Stockholders’ Equity, for purposes of calculating the management fee, could be greater or less than the amount of stockholders’ equity shown on our financial statements. The below table details the management fees incurred during the three and six months ended June 30, 2023 and 2022 (in thousands).

	Three Months Ended				Six Months Ended
Consolidated statements of operations line item:	June 30, 2023		June 30, 2022		June 30, 2023		June 30, 2022
Management fee to affiliate	$	2,061	$	1,958	$	4,136	$	3,920

As of June 30, 2023 and December 31, 2022, we have recorded management fees payable of $2.1 million and $2.1 million, respectively. The management fee payable is included within the "Due to affiliates" item within the "Other liabilities" line item on the consolidated balance sheets.

Incentive fee

The Manager is entitled to an annual incentive fee with respect to each applicable fiscal year, which will be equal to 15% of the amount by which our cumulative adjusted net income from November 22, 2021 exceeds the cumulative hurdle amount, which represents an 8% return (cumulative, but not compounding) on an equity hurdle base consisting of the sum of (i) $341.5 million and (ii) the gross proceeds of any subsequent public or private common stock offerings by us. The annual incentive fee will be payable in cash, or, at the option of our Board of Directors, shares of common stock or a combination of cash and shares.

The Manager waived the annual incentive fee with respect to the fiscal years ending December 31, 2021 and December 31, 2022, and the annual incentive fee will first be payable with respect to the fiscal year ending December 31, 2023. During the three and six months ended June 30, 2023, we did not incur any incentive fee expense.

Expense Reimbursement

Our Manager uses the proceeds from its management fee in part to pay compensation to its officers and personnel, who, notwithstanding that certain of them also are our officers, receive no compensation directly from us. We are required to reimburse our Manager or its affiliates for operating expenses incurred by our Manager or its affiliates on our behalf, including certain salary expenses and other expenses relating to legal, accounting, due diligence and other services. Our reimbursement obligation is not subject to any dollar limitation; however, reimbursements are subject to an annual budget process which combines guidelines from the Management Agreement with oversight by our Board of Directors and discussions with our Manager.

67

The below table details the expense reimbursement incurred during the three and six months ended June 30, 2023 and 2022 (in thousands).

As of June 30, 2023 and December 31, 2022, we recorded a reimbursement payable to our Manager or its affiliates of $2.2 million and $1.3 million, respectively The reimbursement payable to the Manager or its affiliates is included within the "Due to affiliates" item within the "Other liabilities" line item on the consolidated balance sheets.

Share-based compensation

The AG Mortgage Investment Trust, Inc. 2020 Equity Incentive Plan, which became effective on April 15, 2020 following the approval of our stockholders at our 2020 annual meeting of stockholders, provides for a maximum of 666,666 shares of common stock that may be issued under the plan. The maximum number of shares of common stock granted during a single fiscal year to any non-employee director, taken together with any cash fees paid to such non-employee director during any fiscal year, shall not exceed $300,000 in total value (calculating the value of any such awards based on the grant date fair value). As of June 30, 2023, 520,182 shares of common stock were available to be awarded under the 2020 Equity Incentive Plan.

Since inception of the 2020 Equity Incentive Plan and through June 30, 2023, we have granted an aggregate of 146,484 shares of restricted common stock to our independent directors under our 2020 Equity Incentive Plan, all of which have vested.

The AG Mortgage Investment Trust, Inc. 2021 Manager Equity Incentive Plan (the "2021 Manager Plan"), which became effective on April 7, 2021 following the approval of our stockholders at our 2021 annual meeting of stockholders, provides for a maximum of 573,425 shares of common stock that may be subject to awards thereunder to our Manager. As of June 30, 2023, there were no shares or awards issued under the 2021 Manager Plan. Following the execution of the Third Amendment to our management agreement in November 2021 related to the incentive fee, our compensation committee no longer expects to continue its historical practice of making periodic equity grants to the Manager pursuant to the 2021 Manager Equity Incentive Plan.

Unfunded commitments

See Note 12 of the "Notes to Consolidated Financial Statements (unaudited)" for detail on our commitments as of June 30, 2023.

Off-balance sheet arrangements

Our investments in debt and equity of affiliates primarily consist of real estate securities and our interest in AG Arc. Investments in debt and equity of affiliates are accounted for using the equity method of accounting. Certain of our investments in debt and equity of affiliates securitize residential mortgage loans and retain interests in the subordinated tranches of the transferred assets. These retained interests are included in the MATT Non-QM Securities and Re/Non-Performing Securities line items of our investment portfolio. See Note 10 to the "Notes to Consolidated Financial Statements (unaudited)" for a discussion of investments in debt and equity of affiliates.

We record TBA purchases and sales on the trade date and present the purchase or receipt net of the corresponding payable or receivable until the settlement date of the transaction. Refer to Note 7 to the "Notes to Consolidated Financial Statements (unaudited)" for additional detail on TBAs as of June 30, 2023, if applicable.

For additional information on our commitments as of June 30, 2023, refer to Note 12 of the "Notes to Consolidated Financial Statements (unaudited)." We do not expect these commitments, taken as a whole, to be significant to, or to have a material impact on, our overall liquidity or capital resources or our operations.

Critical accounting policies and estimates

We prepare our consolidated financial statements in conformity with GAAP, which requires the use of estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the amounts of income and expenses during the reporting period. These estimates are based, in part, on our judgment and assumptions regarding various economic conditions that we believe are reasonable based on facts and circumstances existing at the time of reporting. We believe that the estimates, judgments and assumptions utilized in the preparation of our consolidated financial statements are prudent and reasonable. Although our estimates contemplate conditions as of June 30, 2023 and how we expect them to change in the future, it is reasonably possible that actual conditions could be different than anticipated in arriving at those estimates, which could materially affect reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the periods presented.

Our most critical accounting policies include (i) Valuation of financial instruments, (ii) Accounting for loans, (iii) Accounting for real estate securities, (iv) Interest income recognition, (v) Financing arrangements, and (vi) Investment consolidation. Our critical accounting estimates are those which require assumptions to be made about matters that are highly uncertain and include (i), (iv), and (vi) above. A discussion of critical accounting policies and estimates is included in our Form 10-K. Our critical accounting policies and estimates have not materially changed since December 31, 2022.

REIT Qualification

We have elected to be treated as a REIT under Sections 856 through 859 of the Internal Revenue Code of 1986, as amended (the "Code"). Our qualification as a REIT depends upon our ability to meet on a continuing basis, through actual investment and operating results, various complex requirements under the Code relating to, among other things, the sources of our gross income, the composition and values of our assets, our distribution levels and the diversity of ownership of our shares. We believe that we are organized in conformity with the requirements for qualification and taxation as a REIT under the Code, and that our manner of operation enables us to meet the requirements for qualification and taxation as a REIT.

We generally need to distribute at least 90% of our ordinary taxable income each year (subject to certain adjustments) to our stockholders in order to qualify as a REIT under the Code. Our ability to make distributions to our stockholders depends, in part, upon the performance of our investment portfolio.

As a REIT, we generally are not subject to U.S. federal income tax on our REIT taxable income that we distribute currently to our stockholders. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal income tax at regular corporate rates and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year during which we lost our REIT qualification. Accordingly, our failure to qualify as a REIT could have a material adverse impact on our results of operations and our ability to pay distributions, if any, to our stockholders. Even if we qualify for taxation as a REIT, we may be subject to some U.S. federal, state and local taxes on our income or property. In addition, any income earned by a domestic taxable REIT subsidiary, or TRS, will be subject to corporate income taxation.

Investment Company Act Exemption

We conduct our operations so that we are not considered an investment company under Section 3(a)(1)(C) of the Investment Company Act. Under Section 3(a)(1)(C) of the Investment Company Act, a company is deemed to be an investment company if it is engaged, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and owns or proposes to acquire "investment securities" having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis (the "40% test"). "Investment securities" do not include, among other things, U.S. government securities and securities issued by majority-owned subsidiaries that (i) are not investment companies and (ii) are not relying on the exceptions from the definition of investment company provided by Section 3(c)(1) or 3(c)(7) of the Investment Company Act.

Conducting our operations so as not to be considered an investment company under the Investment Company Act and the rules and regulations promulgated under the Investment Company Act and SEC staff interpretive guidance limits our ability to make certain investments. For example, these restrictions limit our and our subsidiaries’ ability to invest directly in Agency RMBS mortgage-related securities that represent less than the entire ownership in a pool of mortgage loans or debt and equity tranches of Non-Agency RMBS (in each case to the extent such interest are not retained interest in securitizations consisting of mortgage loans that were owned by us and such securitizations were not sponsored by us in order to obtain financing to acquire additional mortgage loans), certain real estate companies and assets not related to real estate.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary components of our market risk relate to interest rates, liquidity, real estate, credit, prepayment rates, basis, and capital markets risk. While we do not seek to avoid risk completely, we seek to assume risk that can be reasonably quantified from historical experience and to actively manage that risk, to earn sufficient returns to justify taking those risks and to maintain capital levels consistent with the risks we undertake. Many of these risks have become particularly heightened due to sustained inflation, rising mortgage rates, the Federal Reserve's monetary policy actions, and the COVID-19 pandemic.

Interest rate risk

Interest rate risk is highly sensitive to many factors, including governmental monetary, fiscal and tax policies, domestic and international economic and political considerations and other factors beyond our control. We are subject to interest rate risk in connection with both our investments and the financing under our financing arrangements. We generally seek to manage this risk by monitoring the reset index and the interest rate related to our investment portfolio and our financings; by structuring our financing arrangements to have a range of maturity terms, amortizations and interest rate adjustment periods; and by using derivative instruments to adjust interest rate sensitivity of our investment portfolio and borrowings. Our hedging techniques can be highly complex, and the value of our investment portfolio and derivatives may be adversely affected as a result of changing interest rates.

Interest rate effects on net interest income

Our operating results depend in large part upon differences between the yields earned on our investments and our cost of borrowing and upon the effectiveness of our interest rate hedging activities. The majority of our financing arrangements are short term in nature, exclusive of our residential mortgage loans financed through securitized debt. Repurchase agreements financing our securities portfolio or retained interests from our securitizations typically have an initial term between 30 and 90 days while repurchase agreements financing our residential mortgage loans prior to securitization have an initial term of one year. The financing rate on these agreements will generally be determined at the outset of each transaction by reference to prevailing rates plus a spread. As a result, our borrowing costs will tend to increase during periods of rising interest rates as we renew, or "roll", maturing transactions at the higher prevailing rates. When combined with the fact that the income we earn on our fixed interest rate investments will remain substantially unchanged, this will result in a narrowing of the net interest spread between the related assets and borrowings and may even result in losses.

In an attempt to offset the increase in funding costs related to rising interest rates, our Manager may cause us to enter into hedging transactions structured to provide us with positive cash flow in the event interest rates rise. Our Manager accomplishes this through the use of interest rate derivatives. Some hedging strategies involving the use of derivatives are highly complex, may produce volatile returns and may expose us to increased risks relating to counterparty defaults.

Interest rate effects on fair value

Another component of interest rate risk is the effect that changes in interest rates will have on the fair value of the assets that we acquire.

Generally, in a rising interest rate environment, the fair value of our loan and real estate securities portfolios would be expected to decrease, all other factors being held constant. In particular, the portion of our real estate securities and loan portfolios with fixed-rate coupons would be expected to decrease in value more severely than that portion with a floating-rate coupon. This is because fixed-rate coupon assets tend to have significantly more duration, or price sensitivity to changes in interest rates, than floating-rate coupon assets. Fixed-rate assets currently represent a majority of our portfolio.

The fair value of our investment portfolio could change at a different rate than the fair value of our liabilities when interest rates change. We measure the sensitivity of our portfolio to changes in interest rates by estimating the duration of our assets and liabilities. Duration is the approximate percentage change in fair value for an instantaneous 100 basis point parallel shift in the yield curve while assuming all other market risk factors remain constant. In general, our assets have higher duration than our liabilities. In order to reduce this exposure, we use hedging instruments to reduce the gap in duration between our assets and liabilities.

We calculate estimated effective duration (i.e., the price sensitivity to changes in risk-free interest rates) to measure the impact of changes in interest rates on our portfolio value. We estimate duration based on third-party models. Different models and methodologies can produce different effective duration estimates for the same assets. We allocate the net duration by asset type based on the interest rate sensitivity.

70

The following chart details information about our duration gap as of June 30, 2023.

 

Duration (1)(2)	Years
Agency RMBS	0.54
Residential Investments (3)	4.30
Hedges	(2.01)
Duration Gap	2.83

(1)Duration related to financing arrangements is netted within its respective line items.

(2)Duration does not include our investment in AG Arc LLC.

(3)Residential Investments are inclusive of forward purchase commitments to acquire Non-Agency Loans and Agency-Eligible Loans as of June 30, 2023.

The following table quantifies the estimated percent change in GAAP equity, the fair value of our assets, and projected net interest income should interest rates go up or down instantaneously by 25, 50, and 75 basis points, assuming (i) the yield curves of the rate shocks will be parallel to each other and the current yield curve and (ii) all other market risk factors remain constant. These estimates were compiled using a combination of third-party services and models, market data and internal models. All changes in equity, assets, and income are measured as percentage changes from the GAAP equity, assets, and projected net interest income from our base interest rate scenario. The base interest rate scenario assumes spot and forward interest rates existing as of June 30, 2023. Actual results could differ materially from these estimates.

Agency RMBS and Agency-Eligible Loan assumptions attempt to predict default and prepayment activity at projected interest rate levels. To the extent that these estimates or other assumptions do not hold true, actual results will likely differ materially from projections and could result in percentage changes larger or smaller than the estimates in the table below. Moreover, if different models were employed in the analysis, materially different projections could result. In addition, while the table below reflects the estimated impact of interest rate increases and decreases on a static portfolio as of June 30, 2023, our Manager may from time to time sell any of our investments as a part of the overall management of our investment portfolio.

(75)	5.4	%	0.5	%	(0.6)	%

(1)Includes investments held through affiliated entities that are reported as "Investments in debt and equity of affiliates" on our consolidated balance sheet, but excludes AG Arc.

(2)Does not include cash investments, which typically have overnight maturities and are not expected to change in value as interest rates change.

(3)Changes in fair value as a percentage of GAAP equity and assets are inclusive of forward purchase commitments to acquire Non-Agency Loans and Agency-Eligible Loans as of June 30, 2023.

(4)Interest income includes trades settled as of June 30, 2023.

The information set forth in the interest rate sensitivity table above and all related disclosures constitute forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Actual results could differ significantly from those estimated in the foregoing interest rate sensitivity table. See below for additional risks which may impact the fair value of our assets, GAAP equity and net income.

Liquidity risk

Our primary liquidity risk arises from financing long-maturity assets with shorter-term financings primarily in the form of financing arrangements. Our Manager seeks to mitigate our liquidity risks by maintaining a prudent level of leverage, monitoring our liquidity position on a daily basis and maintaining a reasonable cushion of cash and unpledged real estate securities and loans in our portfolio in order to meet future margin calls. In addition, our Manager seeks to further mitigate our

71

liquidity risk by (i) maintaining relationships with a carefully selected group of financing counterparties and (ii) monitoring the ongoing financial stability and future business plans of our financing counterparties.

Liquidity risk – financing arrangements

We pledge mortgage loans or real estate securities and cash as collateral to secure our financing arrangements. Should the fair value of our mortgage loans or real estate securities pledged as collateral decrease (as a result of rising interest rates, changes in prepayment speeds, widening of credit spreads or otherwise), we will likely be subject to margin calls for additional collateral from our financing counterparties. Should the fair value of our mortgage loans or real estate securities decrease materially and suddenly, margin calls will likely increase causing an adverse change to our liquidity position which could result in substantial losses. In addition, we cannot be assured that we will always be able to roll our financing arrangements at their scheduled maturities, which could cause material additional harm to our liquidity position and result in substantial losses. Further, should funding conditions tighten as they did in 2007-2008, 2009 and more recently in March 2020, our financing arrangement counterparties may increase our margin requirements on new financings, including repurchase transactions that we roll at maturity with the same counterparty. This would require us to post additional collateral and would reduce our ability to use leverage and could potentially cause us to incur substantial losses.

Liquidity risk – derivatives

The terms of our interest rate swaps require us to post collateral in the form of cash or Agency RMBS to our counterparties to satisfy two types of margin requirements: variation margin and initial margin.

We and our swap counterparties are both required to post variation margin to each other depending upon the daily moves in prevailing benchmark interest rates. The amount of this variation margin is derived from the mark to market valuation of our swaps. Hence, as our swaps lose value in a falling interest rate environment, we are required to post additional variation margin to our counterparties on a daily basis; conversely, as our swaps gain value in a rising interest rate environment, we are able to recall variation margin from our counterparties. By recalling variation margin from our swaps counterparties, we are able to partially mitigate the liquidity risk created by margin calls on our repurchase transactions during periods of rising interest rates.

Initial margin works differently. Collateral posted to meet initial margin requirements is intended to create a safety buffer to benefit our counterparties if we were to default on our payment obligations under the terms of the swaps and our counterparties were forced to unwind the swap. Initial margin on our centrally cleared trades varies from day to day depending upon various factors, including the absolute level of interest rates and the implied volatility of interest rates. There is a distinctly positive correlation between initial margin, on the one hand, and the absolute level of interest rates and implied volatility of interest rates, on the other hand. As a result, in times of rising interest rates or increasing rate volatility, we anticipate that the initial margin required on our centrally-cleared trades will likewise increase, potentially by a substantial amount. These margin increases will have a negative impact on our liquidity position and will likely impair the intended liquidity risk mitigation effect of our swaps discussed above.

Real estate value risk

Residential property values are subject to volatility and may be affected adversely by a number of factors outside of our control, including, but not limited to, national, regional and local economic conditions (which may be adversely affected by industry slowdowns and other factors); local real estate conditions (such as an oversupply of housing); natural disasters, the effects of climate change (including flooding, drought, and severe weather) and other natural events; construction quality, age and design; demographic factors; and retroactive changes to building or similar codes. Decreases in property values could cause us to suffer losses and reduce the value of the collateral underlying our investment portfolio as well as the potential sale proceeds available to repay our loans in the event of a default. In addition, substantial decreases in property values can increase the rate of strategic defaults by residential mortgage borrowers which can impact and create significant uncertainty in the recovery of principal and interest on our investments.

Credit risk

We are exposed to the risk of potential credit losses from an unanticipated increase in borrower defaults as well as general credit spread widening on any non-agency assets in our portfolio. We seek to manage this risk through our Manager’s pre-acquisition due diligence process and, if available, through the use of non-recourse financing, which limits our exposure to credit losses to the specific pool of collateral which is the subject of the non-recourse financing. Our Manager’s pre-acquisition

72

due diligence process includes the evaluation of, among other things, relative valuation, supply and demand trends, the shape of various yield curves, prepayment rates, delinquency and default rates, recovery of various sectors and vintage of collateral.

The potential effects of sustained inflation, rising mortgage rates, the Federal Reserve's monetary policy actions, and the ongoing COVID-19 pandemic may cause an increase in credit risk of our credit sensitive assets. Any future period of payment deferrals, forbearance, delinquencies, defaults, foreclosures or losses will likely adversely affect our net interest income from residential loans and RMBS investments, the fair value of these assets, our ability to liquidate the collateral that may underlie these investments and obtain additional financing and the future profitability of our investments. Further, in the event of delinquencies, defaults and foreclosure, regulatory changes and policies designed to protect borrowers and renters may slow or prevent us from taking remediation actions.

Prepayment risk

Premiums arise when we acquire real estate assets at a price in excess of the principal balance of the mortgages securing such assets (i.e., par value). Conversely, discounts arise when we acquire assets at a price below the principal balance of the mortgages securing such assets. Premiums paid on our assets are amortized against interest income and accretable purchase discounts on our assets are accreted to interest income. Purchase premiums or discounts on our assets are amortized or accreted over the life of each respective asset using the effective yield method, adjusted for actual prepayment activity. An increase in the prepayment rate, as measured by the CPR, will typically accelerate the amortization of purchase premiums, thereby reducing the yield or interest income earned on such assets. An increase in the prepayment rate will similarly accelerate the accretion of purchase discounts, conversely increasing the yield or interest income earned on such assets. A decrease in the prepayment rate will have a directionally opposite impact on the yield or interest income.

Differences between previously estimated cash flows and current actual and anticipated cash flows caused by changes to prepayment or other assumptions are adjusted retrospectively through a "catch up" adjustment for the impact of the cumulative change in the effective yield through the reporting date for securities accounted for under ASC 320-10 (generally, Agency RMBS) or adjusted prospectively through an adjustment of the yield over the remaining life of the investment for investments accounted for under ASC 325-40 (generally, Non-Agency RMBS and interest-only securities) and mortgage loans accounted for under ASC 310-10.

In addition, our interest rate hedges are structured in part based upon assumed levels of future prepayments within our mortgage loan or real estate securities portfolio. If prepayments are slower or faster than assumed, the life of the real estate securities or mortgage loans will be longer or shorter than assumed, respectively, which could reduce the effectiveness of our Manager’s hedging strategies and may cause losses on such transactions.

Our Manager seeks to mitigate our prepayment risk by investing in real estate assets with a variety of prepayment characteristics.

Basis risk

Basis risk refers to the possible decline in book value triggered by the risk of incurring losses on the fair value of Agency RMBS as a result of widening market spreads between the yields on Agency RMBS and the yields on comparable duration Treasury securities. The basis risk associated with fluctuations in fair value of Agency RMBS may relate to factors impacting the mortgage and fixed income markets other than changes in benchmark interest rates, such as actual or anticipated monetary policy actions by the Federal Reserve, market liquidity, or changes in required rates of return on different assets. Consequently, while we use interest rate swaps and other hedges to protect against moves in interest rates, such instruments will generally not protect our net book value against basis risk.

Capital Market Risk

We are exposed to risks related to the equity capital markets, and our related ability to raise capital through the issuance of our common stock, preferred stock or other equity instruments. We are also exposed to risks related to the debt capital markets, and our related ability to finance our business through revolving facilities or other debt instruments. As a REIT, we are required to distribute a significant portion of our taxable income annually, which constrains our ability to accumulate operating cash flow and therefore may require us to utilize debt or equity capital to finance our business. We seek to mitigate these risks by monitoring the debt and equity capital markets to inform our decisions on the amount, timing, and terms of capital we raise.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining disclosure controls and procedures that are designed to ensure that information the Company is required to disclose in the reports that it files or submits under the Securities Exchange Act of 1934, as amended (the "Exchange Act") is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that the Company’s management, including its principal executive officer and principal financial officer, as appropriate, allow for timely decisions regarding required disclosure.

We have evaluated, with the participation of our principal executive officer and principal financial officer, the effectiveness of our disclosure controls and procedures as of June 30, 2023. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow for timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting

No change occurred in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act) during the period covered by this quarterly report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

74

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

We are at times subject to various legal proceedings and claims arising in the ordinary course of our business. In addition, in the ordinary course of business, we can be and are involved in governmental and regulatory examinations, information gathering requests, investigations and proceedings. As of the date of this report, we are not party to any litigation or legal proceedings, or to our knowledge, any threatened litigation or legal proceedings, which we believe, individually or in the aggregate, would have a material adverse effect on our results of operations or financial condition.

ITEM 1A. RISK FACTORS.

In addition to the risks identified below, please refer to the risks identified under the caption "Risk Factors", in our Annual Report on Form 10-K for the year ended December 31, 2022 and our subsequent filings, which are available on the Securities and Exchange Commission’s website at www.sec.gov, and in the "Forward-Looking Statements" and "Management’s Discussion and Analysis of Financial Condition and Results of Operations" sections herein.

Risks Relating to the Proposed Merger with WMC

Completion of the Merger remains subject to conditions that we cannot control.

The Merger is subject to various closing conditions, including the approval of both our stockholders and the stockholders of WMC. There are no assurances that all of the conditions necessary to consummate the Merger will be satisfied or that the conditions will be satisfied in the time frame expected.

We may fail to realize all of the expected benefits of the Merger or those benefits may take longer to realize than expected.

The full benefits of the Merger may not be realized by us as expected or may not be achieved within the anticipated time-frame, or at all. Failure to achieve the anticipated benefits of the Merger could adversely affect our results of operations or cash flows, cause dilution to our earnings per share or book value per share, decrease or delay the expected accretive effect of the Merger, and negatively impact the share price of our common stock.

In addition, we will be required to devote significant attention and resources prior to closing to prepare for the post-closing operation of the combined company. Post-closing, we may be required to devote significant attention and resources to successfully integrate the WMC portfolio and operating business into our existing structure. This integration process may disrupt our business and, if ineffective, would limit the anticipated benefits of the Merger and could adversely affect our business.

We will incur direct and indirect costs as a result of the Merger.

We will incur substantial expenses in connection with and as a result of completing the WMC acquisition (including the Company's payment of the TPT Termination Fee) and, following completion, we may incur additional expenses in connection with combining the businesses, operations, policies and procedures of the two companies. Factors beyond our control could affect the total amount or timing of these expenses, many of which, by their nature, are difficult to estimate accurately.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.

On August 3, 2022, the Company’s Board of Directors authorized the 2022 Repurchase Program to repurchase up to $15.0 million of the Company's outstanding common stock. On May 4, 2023, the Company's Board of Directors authorized the 2023 Repurchase Program to repurchase up to $15.0 million of the Company’s outstanding common stock on substantially the same terms as the 2022 Repurchase Program. The Board's authorizations do not have an expiration date. The following table presents information related to our purchases of our common stock pursuant to the 2022 Repurchase Program during the three months ended June 30, 2023.

Organization

Organization

AG Mortgage Investment Trust, Inc. (the "Company") 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.

The Company’s assets, excluding its ownership in Arc Home, include Residential Investments and Agency RMBS. Currently, its Residential Investments primarily consist of newly originated Non-Agency Loans and Agency-Eligible 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.
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 Residential Mortgage-Backed Securities ("RMBS")(2)	•Non-Agency RMBS represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. The mortgage loan collateral consists of either Non-Agency Loans or Agency-Eligible Loans.
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.

(1)These investments are included in the "Securitized residential mortgage loans, at fair value," "Securitized residential mortgage loans held for sale, at fair value," "Residential mortgage loans, at fair value," and "Residential mortgage loans held for sale, 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.

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. ("Angelo Gordon"), a privately-held, SEC-registered investment adviser. The Manager has delegated to 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.

Accounting Policies [Abstract]

Summary of significant accounting policies

Summary of significant accounting policies

Consolidation and basis of presentation

The accompanying unaudited consolidated financial statements and related notes have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. For the three months ended June 30, 2022, the Company reclassified $2.5 million and $1.3 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. For the six months ended June 30, 2022, the Company reclassified $5.2 million and $2.3 million of other operating expenses into the "Non-investment related expenses" and "Investment related expenses" line items on the consolidated statement of operations, respectively. Furthermore, for the three and six months ended June 30, 2022, the Company reclassified $1.0 million and $2.0 million of servicing fees into the "Investment related expenses" line item on the consolidated statement of operations, respectively. These expenses were reclassified to conform to the current year presentation of expenses. In the opinion of management, all adjustments considered necessary for a fair statement of the Company’s financial position, results of operations, and cash flows have been included for the interim period and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year.

Significant accounting policies

There have been no significant changes to the Company's accounting policies included in Note 2 to the consolidated financial statements of the Company’s Form 10-K for the year ended December 31, 2022. These unaudited consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes for the year ended December 31, 2022 included in the Company’s Form 10-K.

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.

Investment consolidation

An entity is a variable interest entity ("VIE") if the equity investors (i) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (ii) are unable to direct the entity’s activities or (iii) are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of Accounting Standards Codification ("ASC") 810-10, "Consolidation" are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company determines that consolidation is not required, it will then assess whether the transfer of the underlying assets would qualify as a sale, should be accounted for as secured financings under GAAP, or should be accounted for as an equity method investment, depending on the circumstances.

A Special Purpose Entity ("SPE") is an entity designed to fulfill a specific limited need of the company that organized it. SPEs are often used to facilitate transactions that involve securitizing financial assets or resecuritizing previously securitized financial assets. The objective of such transactions may include obtaining non-recourse financing, obtaining liquidity or refinancing the underlying securitized financial assets on improved terms. Securitization involves transferring assets to an SPE to convert all or a portion of those assets into cash before they would have been realized in the normal course of business through the SPE’s issuance of debt or equity instruments. Investors in an SPE usually have recourse only to the assets in the SPE and depending on the overall structure of the transaction, may benefit from various forms of credit enhancement, such as over-collateralization

in the form of excess assets in the SPE, priority with respect to receipt of cash flows relative to holders of other debt or equity instruments issued by the SPE, or a line of credit or other form of liquidity agreement that is designed with the objective of ensuring that investors receive principal and/or interest cash flow on the investment in accordance with the terms of their investment agreement.

The Company enters into securitization transactions collateralized by its Non-Agency Loans/Agency-Eligible Loans and re- and non-performing loans (the trusts in which these loans are deposited are referred to as "Non-Agency VIEs" and "RPL/NPL VIEs", respectively, and collectively "Residential Mortgage Loan VIEs"), which may result in the Company consolidating the respective VIEs that are created to facilitate these securitizations. Based on the evaluations of each VIE, the Company may conclude that the VIEs should be consolidated and, as a result, transferred assets of these VIEs would be determined to be secured borrowings. Upon consolidation, the Company elected the fair value option pursuant to ASC 825 for the assets and liabilities of the Residential Mortgage Loan VIEs. Electing the fair value option allows the Company to record changes in fair value in the consolidated statement of operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all activities will be recorded in a similar manner. The Company applied the guidance under ASC 810-10 (Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity) whereby the Company determines whether the fair value of the assets or liabilities of the Residential Mortgage Loan VIEs are more observable as a basis for measuring the less observable financial instruments. The Company has determined that the fair value of the liabilities of the Residential Mortgage Loan VIEs are more observable since the prices for these liabilities are more easily determined as similar instruments trade more frequently on a relative basis than the individual assets of the VIEs. See Note 3 for more detail regarding the Residential Mortgage Loan VIEs and Note 5 for more detail related to the Company's determination of fair value for the assets and liabilities included within these VIEs.

Recent accounting pronouncements

In March 2020, FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting and may be elected over time as reference rate reform activities occur. This ASU is effective as of March 12, 2020 and was amended by ASU 2022-06 to sunset on December 31, 2024. The ASU applies to all entities that have contracts, hedging relationships and other transactions that reference LIBOR and certain other reference rates that are expected to be discontinued. However, it cannot be applied to contract modifications that occur after December 31, 2024. With certain exceptions, this ASU also cannot be applied to hedging relationships entered into or evaluated after that date. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance.

As of June 30, 2023, the Company has transitioned from LIBOR to an alternative benchmark. The adoption of ASU 2020-04 and the LIBOR transition did not have a material impact on the consolidated financial statements. The Company's primary exposure to LIBOR has historically included its financing arrangements and derivative contracts. In addition, the Company's Series C Preferred Stock is set to transition to a floating rate in September of 2024. As of June 30, 2023, the Company no longer has derivative contracts indexed to LIBOR and all LIBOR-based financing arrangements have transitioned to alternative benchmark rates. The Company does not currently intend to amend the Series C Preferred Stock to change the existing LIBOR cessation fallback language.

Fair Value Disclosures [Abstract]

Fair value measurements

Fair value measurements The fair value of the Company's financial instruments is determined in accordance with the provisions of ASC 820, "Fair Value Measurements and Disclosures." When possible, the Company determines fair value using third-party data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices and may include quoted prices for similar assets and liabilities in active markets. Level 3 inputs are significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used and reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.

The following tables present the Company’s financial instruments measured at fair value on a recurring basis as of June 30, 2023 and December 31, 2022 (in thousands).

(1)Includes Securitized residential mortgage loans held for sale as of June 30, 2023.

(2)Includes Residential mortgage loans held for sale as of June 30, 2023 and December 31, 2022.

(3)As of June 30, 2023, the Company applied a reduction in fair value of $10.9 million and $0.7 million to its interest rate swap assets and liabilities, respectively, related to variation margin with a corresponding increase or decrease in restricted cash. As of December 31, 2022, the Company applied a reduction in fair value of $17.3 million to its interest rate swap assets related to variation margin with a corresponding increase in restricted cash, net of collateral posted by the Company's derivative counterparties. Derivative assets and liabilities are included in the "Other assets" and "Other liabilities" line items on the consolidated balance sheets, respectively. Refer to Note 7 for more information on the Company's derivatives.

(4)The Company classifies highly liquid investments with original maturities of three months or less from the date of purchase as cash equivalents. Cash equivalents may include cash invested in money market funds and are carried at cost, which approximates fair value.

(5)The table above includes the Company's investment in AG Arc, which is included in its "Investments in debt and equity of affiliates" line item on the consolidated balance sheets, as the Company has chosen to elect the fair value option with respect to its investment pursuant to ASC 825.

The valuation of the Company’s residential mortgage loans, securitized debt relating to the Residential Mortgage Loan VIEs, certain securities, and forward purchase commitments is determined by the Manager using third-party pricing services where available, valuation analyses from third-party pricing service providers, or model-based pricing. Third-party pricing service providers conduct independent valuation analyses based on a review of source documents, available market data, and comparable investments. The analyses provided by valuation service providers are reviewed and considered by the Manager. The evaluation considers the underlying characteristics of each loan, which are observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company also considers loan servicing data, as available, forward interest rates, general economic conditions, home price index forecasts, and valuations of the underlying properties. The variables considered most significant to the determination of the fair value of the Company's residential mortgage loans, securitized debt, and forward purchase commitments include market-implied discount rates, projections of default rates, delinquency rates, prepayment rates, loss severity, recovery rates, reperformance rates, timeline to liquidation, and, for forward purchase commitments, pull-through rates. The Company and third-party pricing service providers use loan level data and macro-economic inputs to generate loss adjusted cash flows and other information in determining the fair value. Because of the inherent uncertainty of such valuation, the fair value established for mortgage loans, securitized debt, and forward purchase commitments held by the Company may differ from the fair value that would have been established if a ready market existed for these mortgage loans.

Fair values for the Company’s securities and derivatives may be based upon prices obtained from third-party pricing services or broker quotations. The valuation methodology of the Company’s third-party pricing services incorporates commonly used market pricing methods, including a spread measurement to various indices, which are observable inputs. The evaluation also considers the underlying characteristics of each investment, which are also observable inputs, including: coupon, maturity date, loan age, reset date, collateral type, periodic and life cap, geography, and prepayment speeds. The Company collects and considers current market intelligence on all major markets, including benchmark security evaluations and bid-lists from various sources, when available. As part of the Company’s risk management process, the Company reviews and analyzes all prices obtained by comparing prices to recently completed transactions involving the same or similar investments on or near the reporting date. If, in the opinion of the Manager, one or more prices reported to the Company are not reliable or unavailable, the Manager reviews the fair value based on characteristics of the investment it receives from the issuer and available market information.

The Company's investment in Arc Home is evaluated on a periodic basis using a market approach. In applying the market approach, fair value is determined by multiplying Arc Home's book value by a relevant valuation multiple observed based on a range of comparable public entities or transactions, adjusted by management as appropriate for differences between the investment and the referenced comparables. The evaluation also considers the underlying financial performance of Arc Home, general economic conditions, and relevant trends within the mortgage banking industry.

Changes in the market environment and other events that may occur over the life of these investments may cause the gains or losses ultimately realized to be different than the valuations currently estimated. The significant unobservable inputs used in the fair value measurement of the Company’s loans and securities are yields, prepayment rates, probability of default, and loss severity in the event of default. Significant increases (decreases) in any of those inputs in isolation would result in a significantly lower (higher) fair value measurement. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for prepayment rates. The significant unobservable input used in the fair value measurement of the Company’s investment in Arc Home is the book value multiple. Significant increases (decreases) in the multiple applied would result in a significantly higher (lower) fair value measurement.

The Company did not have any transfers of assets or liabilities between Levels 1 and 2 of the fair value hierarchy during the three and six months ended June 30, 2023 and 2022.

The Company did not have any transfers between the Levels 2 and 3 of the fair value hierarchy during the three and six months ended June 30, 2023 and 2022. Transfers into the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of reduced levels of market transparency. Transfers out of the Level 3 category of the fair value hierarchy occur due to instruments exhibiting indications of increased levels of market transparency. Indications of increases or decreases in levels of market transparency include a change in observable transactions or executable quotes involving these instruments or similar instruments. Changes in these indications could impact price transparency, and thereby cause a change in level designations in future periods.

The following tables present additional information about the Company’s assets and liabilities which are measured at fair value on a recurring basis for which the Company has utilized Level 3 inputs to determine fair value.

Derivative and other instruments eligible for offset are presented gross on the consolidated balance sheets as of June 30, 2023 and December 31, 2022, if applicable.

The posting of collateral is generally bilateral, meaning that if the fair value of the Company’s derivatives increases, its counterparty must post collateral. As of June 30, 2023, the Company's restricted cash balance included $15.7 million of collateral related to certain derivatives, of which $5.6 million represents cash collateral posted by the Company and $10.1 million represents amounts related to variation margin. As of December 31, 2022, the Company's restricted cash balance included $9.6 million of collateral related to certain derivatives, of which $1.3 million represents cash collateral posted by the Company and $8.3 million represents amounts related to variation margin.

Income taxes

Income Tax Disclosure [Abstract]

Income taxes

Income taxes

The Company conducts its operations to qualify and be taxed as a REIT. As a REIT, the Company is not subject to federal income tax to the extent that it makes qualifying distributions to its stockholders, and provided it satisfies on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution, and stock ownership tests. The state and local tax jurisdictions for which the Company is subject to tax-filing obligations recognize the Company’s status as a REIT, and therefore, the Company generally does not pay income tax in such jurisdictions. The Company may, however, be subject to certain minimum state and local tax filing fees as well as certain excise, franchise, or business taxes.

Excise tax represents a non-deductible 4% tax on the required amount of the Company’s ordinary income and net capital gains not distributed during the year. The expense is calculated in accordance with applicable tax regulations. For the three and six months ended June 30, 2023 and 2022, the Company did not record any excise tax.

Taxable REIT Subsidiaries

The Company elected to treat certain domestic subsidiaries as taxable REIT subsidiaries ("TRSs"). The Company’s financial results are generally not expected to reflect provisions for current or deferred income taxes, except for any activities conducted through one or more TRSs that are subject to corporate income taxation. Currently, the Company has wholly owned domestic TRSs that are taxable as corporations and subject to U.S. federal, state, and local income tax on net income at the applicable corporate rates. The federal statutory rate for the three and six months ended June 30, 2023 and 2022 was 21%. The Company’s effective tax rate differs from its combined U.S. federal, state, and local corporate statutory tax rate primarily due to income earned at the REIT, which is not subject to tax, due to the deduction for qualifying distributions made by the Company, and any change in the valuation allowance as disclosed in further detail below. The tax expense attributable to its TRS is recorded in the "Non-investment related expenses" line item on the consolidated statement of operations. The below table details the tax expense attributable to the TRS for the three and six months ended June 30, 2023 and 2022 (in thousands).

	Three Months Ended				Six Months Ended

Income tax expense	$	—	$	6	$	225	$	15

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting and tax reporting purposes at the TRS level. As of June 30, 2023 and December 31, 2022, the Company recorded a deferred tax asset of approximately $30.7 million and $30.2 million, respectively, relating to net operating loss carryforwards, capital loss carryforwards, and basis differences of certain investments held within TRSs. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which temporary differences become deductible. The Company concluded it is more likely than not the deferred tax asset will not be realized and established a full valuation allowance as of June 30, 2023 and December 31, 2022.

Uncertain Income Tax Positions

Based on its analysis of any potential uncertain income tax positions, the Company concluded it did not have any uncertain tax positions that meet the recognition or measurement criteria of ASC 740 as of June 30, 2023 and December 31, 2022. The Company’s federal income tax returns for the last three tax years are open to examination by the Internal Revenue Service. There are no ongoing U.S. federal, state or local tax examinations related to the Company. In the event that the Company incurs income tax related interest and penalties, its policy is to classify them as a component of provision for income taxes.

Company pays for repurchases of its common stock, excluding any unrealized gains, losses or other non-cash items that have impacted stockholders’ equity as reported in the Company’s financial statements prepared in accordance with GAAP, regardless of whether such items are included in other comprehensive income or loss, or in net income, and excluding one-time events pursuant to changes in GAAP, and certain other non-cash charges after discussions between the Manager and the Company’s independent directors and after approval by a majority of the Company’s independent directors. Stockholders’ Equity, for purposes of calculating the management fee, could be greater or less than the amount of stockholders’ equity shown on the Company’s financial statements.

On August 3, 2022, the Company's Board of Directors authorized a stock repurchase program (the "2022 Repurchase Program") to repurchase up to $15.0 million of the Company’s outstanding common stock on substantially the same terms as the 2015 Repurchase Program. The 2022 Repurchase Program does not have an expiration date and permits the Company to repurchase its shares through various methods, including open market repurchases, privately negotiated block transactions and Rule 10b5-1 plans. The Company may repurchase shares of its common stock from time to time in compliance with SEC regulations and other legal requirements. The extent to which the Company repurchases its shares, and the timing, manner, price, and amount of any such repurchases, will depend upon a variety of factors including market conditions and other corporate considerations as determined by the Company’s management, as well as the limits of the 2022 Repurchase Program and the Company's liquidity and business strategy. The 2022 Repurchase Program does not obligate the Company to acquire any particular amount of shares and may be modified or discontinued at any time. As of June 30, 2023, approximately $1.5 million of common stock remained authorized for future share repurchases under the 2022 Repurchase Program. The table below details the Company's share repurchases under the 2022 Repurchase Program during the six months ended June 30, 2023:

On May 4, 2023, the Company's Board of Directors authorized a stock repurchase program (the "2023 Repurchase Program") to repurchase up to $15.0 million of the Company’s outstanding common stock on substantially the same terms as the 2022 Repurchase Program. As of June 30, 2023, the full $15.0 million authorized amount remains available for repurchase under the 2023 Repurchase Program. This authorization is in addition to the amount remaining under the 2022 Repurchase Program.

On February 22, 2021, the Company's Board of Directors authorized a stock repurchase program (the "Preferred Repurchase Program") pursuant to which the Company's Board of Directors granted a repurchase authorization to acquire shares of the Company's 8.25% Series A Cumulative Redeemable Preferred Stock ("Series A Preferred Stock"), 8.00% Series B Cumulative Redeemable Preferred Stock ("Series B Preferred Stock"), and 8.000% Series C Fixed-to-Floating Rate Cumulative Redeemable Preferred Stock ("Series C Preferred Stock") having an aggregate value of up to $20.0 million. No share repurchases under the Preferred Repurchase Program have been made since its authorization.

Shares of stock repurchased by the Company under any repurchase program, if any, will be cancelled and, until reissued by the Company, will be deemed to be authorized but unissued shares of its stock as required by Maryland law. The cost of the

acquisition by the Company of shares of its own stock in excess of the aggregate par value of the shares first reduces additional paid-in capital, to the extent available, with any residual cost applied against retained earnings.

Equity distribution agreements

The Company has entered into an equity distribution agreement with each of Credit Suisse Securities (USA) LLC and JMP Securities LLC (collectively, the "Sales Agents"), which the Company refers to as the "Equity Distribution Agreements," pursuant to which the Company may sell up to $100.0 million aggregate offering price of shares of its common stock from time to time through the Sales Agents under the Securities Act of 1933. The Company did not issue any shares of common stock under the Equity Distribution Agreements during the three and six months ended June 30, 2023 and 2022.

The Company is authorized to designate and issue up to 50.0 million shares of preferred stock, par value $0.01 per share, in one or more classes or series. As of June 30, 2023 and December 31, 2022, there were 1.7 million, 3.7 million, and 3.7 million of Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock, respectively, issued and outstanding.

Under such circumstances, holders of the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock voting together as a single class with the holders of all other classes or series of its preferred stock upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock will be entitled to vote to elect two additional directors to the Company’s Board of Directors until all unpaid dividends have been paid or declared and set apart for payment. In addition, certain material and adverse changes to the terms of any series of the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock cannot be made without the affirmative vote of holders of at least two-thirds of the outstanding shares of the series of the Company's Series A Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock whose terms are being changed.

On August 8, 2023, concurrently with the termination by WMC of the TPT Merger Agreement, the Company, on behalf of WMC, paid to Terra Property Trust, Inc. a termination fee of $3.0 million as required by the TPT Merger Agreement (the "TPT Termination Fee").

Under the terms of the Merger Agreement, at the effective time of the Merger (the "Effective Time"), each outstanding share of WMC common stock will be converted into the right to receive the following (the "Per Share Merger Consideration"): (i) 1.50 shares, or 9.2 million shares in aggregate, of the Company's common stock pursuant to a fixed exchange ratio (subject to adjustment for transaction expenses); and (ii) the per share portion of a cash payment from the Manager equal to the lesser of $7.0 million or approximately 9.9% of the aggregate Per Share Merger Consideration (any difference between $7.0 million and the approximately 9.9% cap will be used to benefit the combined company post-closing by offsetting reimbursable expenses that would otherwise be payable to the Manager). Additionally, the Manager, which will be the manager of the combined

company, will waive $2.4 million of management fees owed to it in the first year post-closing. Cash will be paid in lieu of any fractional shares of the Company's common stock that would otherwise have been received as a result of the Merger. For purposes of the transaction expenses adjustment, WMC's transaction expenses exclude (i) a $7.0 million termination fee payable by WMC to its existing manager in connection with the termination of the existing WMC management agreement, (ii) accrued but unpaid management fees and unreimbursed expenses owed to WMC's manager, (iii) transfer taxes, (iv) the costs of a D&O tail policy, and (v) the TPT Termination Fee. Additionally, at the Effective Time, M. Christian Mitchell and Lisa G. Quateman (together, the "WMC Director Designees"), each an independent director currently serving on WMC's board of directors, will be appointed to the Company's Board of Directors. The Company has further agreed to nominate the WMC Director Designees to the Company's Board of Directors at its next annual stockholder meeting following the Effective Time.

The Merger is expected to close in the fourth quarter of 2023, subject to the respective approvals by the Company's stockholders and WMC's stockholders and other customary closing conditions set forth in the Merger Agreement.

In connection with the proposed Merger with WMC, the Company and the Manager entered into an amendment (the "MITT Management Agreement Amendment") to the management agreement, pursuant to which (i) 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 occurs, and (ii) the Manager will waive its right to seek reimbursement from the Company for any expenses otherwise reimbursable by the Company under the management agreement in an amount equal to the excess, if any, of $7.0 million over the aggregate cash portion of the Per Share Merger Consideration paid by the Manager to the holders of WMC common stock in the Merger. The amendment will become effective automatically upon the closing of the Merger, and will have no force and effect if the Merger does not close.

Accounting Policies [Abstract]

Consolidation and basis of presentation

The accompanying unaudited consolidated financial statements and related notes have been prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.

Use of estimates

Use of estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results may differ from those estimates.

Investment consolidation

Investment consolidation

An entity is a variable interest entity ("VIE") if the equity investors (i) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support, (ii) are unable to direct the entity’s activities or (iii) are not exposed to the entity’s losses or entitled to its residual returns. VIEs within the scope of Accounting Standards Codification ("ASC") 810-10, "Consolidation" are required to be consolidated by their primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. This determination can sometimes involve complex and subjective analyses. Further, ASC 810-10 also requires ongoing assessments of whether an enterprise is the primary beneficiary of a VIE. In accordance with ASC 810-10, all transferees, including variable interest entities, must be evaluated for consolidation. If the Company determines that consolidation is not required, it will then assess whether the transfer of the underlying assets would qualify as a sale, should be accounted for as secured financings under GAAP, or should be accounted for as an equity method investment, depending on the circumstances.

A Special Purpose Entity ("SPE") is an entity designed to fulfill a specific limited need of the company that organized it. SPEs are often used to facilitate transactions that involve securitizing financial assets or resecuritizing previously securitized financial assets. The objective of such transactions may include obtaining non-recourse financing, obtaining liquidity or refinancing the underlying securitized financial assets on improved terms. Securitization involves transferring assets to an SPE to convert all or a portion of those assets into cash before they would have been realized in the normal course of business through the SPE’s issuance of debt or equity instruments. Investors in an SPE usually have recourse only to the assets in the SPE and depending on the overall structure of the transaction, may benefit from various forms of credit enhancement, such as over-collateralization

in the form of excess assets in the SPE, priority with respect to receipt of cash flows relative to holders of other debt or equity instruments issued by the SPE, or a line of credit or other form of liquidity agreement that is designed with the objective of ensuring that investors receive principal and/or interest cash flow on the investment in accordance with the terms of their investment agreement.

The Company enters into securitization transactions collateralized by its Non-Agency Loans/Agency-Eligible Loans and re- and non-performing loans (the trusts in which these loans are deposited are referred to as "Non-Agency VIEs" and "RPL/NPL VIEs", respectively, and collectively "Residential Mortgage Loan VIEs"), which may result in the Company consolidating the respective VIEs that are created to facilitate these securitizations. Based on the evaluations of each VIE, the Company may conclude that the VIEs should be consolidated and, as a result, transferred assets of these VIEs would be determined to be secured borrowings. Upon consolidation, the Company elected the fair value option pursuant to ASC 825 for the assets and liabilities of the Residential Mortgage Loan VIEs. Electing the fair value option allows the Company to record changes in fair value in the consolidated statement of operations, which, in management's view, more appropriately reflects the results of operations for a particular reporting period as all activities will be recorded in a similar manner. The Company applied the guidance under ASC 810-10 (Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity) whereby the Company determines whether the fair value of the assets or liabilities of the Residential Mortgage Loan VIEs are more observable as a basis for measuring the less observable financial instruments. The Company has determined that the fair value of the liabilities of the Residential Mortgage Loan VIEs are more observable since the prices for these liabilities are more easily determined as similar instruments trade more frequently on a relative basis than the individual assets of the VIEs. See Note 3 for more detail regarding the Residential Mortgage Loan VIEs and Note 5 for more detail related to the Company's determination of fair value for the assets and liabilities included within these VIEs.

Recent accounting pronouncements

Recent accounting pronouncements

In March 2020, FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." This ASU provides temporary optional guidance intended to ease the burden of reference rate reform on financial reporting and may be elected over time as reference rate reform activities occur. This ASU is effective as of March 12, 2020 and was amended by ASU 2022-06 to sunset on December 31, 2024. The ASU applies to all entities that have contracts, hedging relationships and other transactions that reference LIBOR and certain other reference rates that are expected to be discontinued. However, it cannot be applied to contract modifications that occur after December 31, 2024. With certain exceptions, this ASU also cannot be applied to hedging relationships entered into or evaluated after that date. The guidance provides optional expedients and exceptions for applying existing guidance to contract modifications, hedging relationships and other transactions that are expected to be affected by reference rate reform and meet certain scope guidance.

As of June 30, 2023, the Company has transitioned from LIBOR to an alternative benchmark. The adoption of ASU 2020-04 and the LIBOR transition did not have a material impact on the consolidated financial statements. The Company's primary exposure to LIBOR has historically included its financing arrangements and derivative contracts. In addition, the Company's Series C Preferred Stock is set to transition to a floating rate in September of 2024. As of June 30, 2023, the Company no longer has derivative contracts indexed to LIBOR and all LIBOR-based financing arrangements have transitioned to alternative benchmark rates. The Company does not currently intend to amend the Series C Preferred Stock to change the existing LIBOR cessation fallback language.

Fair value measurements

The fair value of the Company's financial instruments is determined in accordance with the provisions of ASC 820, "Fair Value Measurements and Disclosures." When possible, the Company determines fair value using third-party data sources. ASC 820 establishes a hierarchy that prioritizes the inputs to valuation techniques. Level 1 inputs are observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2 inputs are observable inputs other than quoted prices and may include quoted prices for similar assets and liabilities in active markets. Level 3 inputs are significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used and reflect the Company’s assumptions about the factors that market participants would use in pricing an asset or liability, and would be based on the best information available. In certain cases, inputs used to measure fair value fall into different levels of the fair value hierarchy. In such cases, the level at which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement.

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.
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 Residential Mortgage-Backed Securities ("RMBS")(2)	•Non-Agency RMBS represent fixed- and floating-rate RMBS issued by entities other than U.S. GSEs or agencies of the U.S. government. The mortgage loan collateral consists of either Non-Agency Loans or Agency-Eligible Loans.
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.
