NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 – Organization and Business Operations

Invesco Mortgage Capital Inc. (the “Company” or “we”) is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS”) and other mortgage-related assets.

As of March 31, 2024, we were invested in:

•residential mortgage-backed securities (“RMBS”) that are guaranteed by a U.S. government agency such as the Government National Mortgage Association (“Ginnie Mae”), or a federally chartered corporation such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (collectively “Agency RMBS”);

•commercial mortgage-backed securities (“CMBS”) that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Fannie Mae or Freddie Mac (collectively "Agency CMBS");

•CMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency CMBS”); and

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency RMBS”).

During the periods presented in these condensed consolidated financial statements, we also invested in U.S. Treasury securities and real estate-related financing arrangements in the form of unconsolidated ventures.

We conduct our business through IAS Operating Partnership L.P. (the “Operating Partnership”) and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our “Manager”), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. (“Invesco”), a leading independent global investment management firm.

We elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the “Investment Company” definition under the Investment Company Act of 1940, as amended (the “1940 Act”).

Note 2 – Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2023.

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed securities and allowances for credit losses. Actual results may differ from those estimates.

Significant Accounting Policies

There have been no changes to our accounting policies included in Note 2 to the consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2023.

Note 6 – Borrowings

We finance the majority of our investment portfolio through repurchase agreements. Our repurchase agreements bear interest at a contractually agreed upon rate and generally have maturities ranging from one to six months. We account for our repurchase agreements as secured borrowings since we maintain effective control of the financed assets. Our repurchase agreements are subject to certain financial covenants. We were in compliance with all of these covenants as of March 31, 2024.

The following tables summarize certain characteristics of our borrowings as of March 31, 2024 and December 31, 2023. Refer to Note 7 - "Collateral Positions" for collateral pledged and held under our repurchase agreements.

Note 7 - Collateral Positions

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, and interest rate swaps as of March 31, 2024 and December 31, 2023. Refer to Note 2 - "Summary of Significant Accounting Policies - Fair Value Measurements" of our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 for a description of how we determine fair value. Agency RMBS and Agency CMBS collateral pledged is included in mortgage-backed securities on our condensed consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps is classified as restricted cash on our condensed consolidated balance sheets.

Cash collateral held that is not restricted for use is included in cash and cash equivalents on our condensed consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of March 31, 2024 and December 31, 2023, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets.

Repurchase Agreements

Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls.

The ratio of our total repurchase agreements collateral pledged to our total repurchase agreements outstanding was 105% as of March 31, 2024 (December 31, 2023: 106%) based on the fair value of the securities as reported in our condensed consolidated balance sheets.

Interest Rate Swaps

As of March 31, 2024 and December 31, 2023, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange (“CME”) and LCH Limited (“LCH”) through a Futures Commission Merchant (“FCM”). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on

13

derivative instruments, net in our condensed consolidated statements of operations. Certain of our FCM agreements include cross default provisions.

Note 8 – Derivatives and Hedging Activities

The following table summarizes changes in the notional amount of our derivative instruments during 2024.

$ in thousands	Notional Amount as of December 31, 2023	Additions	Settlement, Termination, Expiration or Exercise	Notional Amount as of March 31, 2024
Interest Rate Swaps	4,065,000	1,335,000	(1,135,000)	4,265,000
Total	4,065,000	1,335,000	(1,135,000)	4,265,000

Refer to Note 7 - "Collateral Positions" for further information regarding our collateral pledged to and received from our derivative counterparties.

Interest Rate Swaps

At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority of our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of floating-rate amounts over the life of the agreements without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy.

Amounts recorded in accumulated other comprehensive income before we discontinued cash flow hedge accounting for our interest rate swaps were reclassified to interest expense on the condensed consolidated statements of operations as interest was accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $4.5 million as a decrease to interest expense during the three months ended March 31, 2023. As of March 31, 2024 and December 31, 2023, there were no gains or losses on discontinued cash flow hedges remaining in accumulated other comprehensive income.

As of March 31, 2024 and December 31, 2023, we had interest rate swaps whereby we pay interest at a fixed rate and receive floating interest based on the secured overnight financing rate (“SOFR”) with the following maturities outstanding.

TBAs

We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS. We did not have any TBAs outstanding as of March 31, 2024 and December 31, 2023.

Note 9 – Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the condensed consolidated balance sheets.

The following tables present information about the assets and liabilities that are subject to master netting arrangements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $131,000 as of March 31, 2024 (December 31, 2023: asset of $939,000) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Note 10 – Fair Value of Financial Instruments

A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows:

•Level 1 Inputs – Quoted prices for identical instruments in active markets.

•Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•Level 3 Inputs – Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities measured at fair value on a recurring basis.

(3)Our investment in an unconsolidated venture was valued using the net asset value (“NAV”) as a practical expedient and was not subject to redemption, although investors could sell or transfer their interest at the approval of the general partner of the underlying funds. The unconsolidated venture made its final distribution in the first quarter of 2024.

The following table presents the carrying value and estimated fair value of our financial instruments that are not carried at fair value on the condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023.

Total	4,393,908	4,393,901	4,458,695	4,458,662

The estimated fair value of repurchase agreements is a Level 3 fair value measurement based on an expected present value technique. This method discounts future estimated cash flows using rates we determined best reflect current market interest rates that would be offered for repurchase agreements with similar characteristics and credit quality.

Note 11 – Related Party Transactions

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 we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. The costs of support personnel provided by our Manager for the three months ended March 31, 2024 reimbursed or reimbursable by us were $231,000 (March 31, 2023: $409,000).

Management Fee

We pay our Manager a fee equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors.

We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager.

Expense Reimbursement

We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, legal services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation.

The following table summarizes the costs incurred on our behalf by our Manager during the three months ended March 31, 2024 and 2023.

Note 12 – Stockholders’ Equity

Preferred Stock

In May 2022, our board of directors approved a share repurchase program for our Series B and Series C Preferred Stock. During the three months ended March 31, 2024, we repurchased and retired 93,347 shares of Series B Preferred Stock and 95,917 shares of Series C Preferred Stock. During the three months ended March 31, 2023, we did not repurchase any shares of preferred stock.

After December 27, 2024, holders are entitled to receive dividends at a floating rate equal to three-month CME Term SOFR and the applicable credit spread adjustment (0.26161%) plus a spread of 5.18% of the $25.00 liquidation preference per annum. Dividends are cumulative and payable quarterly in arrears.

Holders of our Series C Preferred Stock are entitled to receive dividends at an annual rate of 7.50% of the liquidation preference of $25.00 per share or $1.875 per share per annum until September 27, 2027.

ITEM 2.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

In this quarterly report on Form 10-Q, or this "Quarterly Report," we refer to Invesco Mortgage Capital Inc. and its consolidated subsidiaries as "we," "us," "our Company," or "our," unless we specifically state otherwise or the context indicates otherwise. We refer to our external manager, Invesco Advisers, Inc., as our "Manager," and we refer to the indirect parent company of our Manager, Invesco Ltd. together with its consolidated subsidiaries (which does not include us), as "Invesco."

The following discussion should be read in conjunction with our condensed consolidated financial statements and the accompanying notes to our condensed consolidated financial statements, which are included in Item 1 of this Quarterly Report, as well as the information contained in our most recent Form 10-K filed with the Securities and Exchange Commission (the “SEC”).

Forward-Looking Statements

We make forward-looking statements in this Quarterly Report and other filings we make with the SEC within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and such statements are intended to be covered by the safe harbor provided by the same. Forward-looking statements are subject to substantial risks and uncertainties, many of which are difficult to predict and are generally beyond our control. These forward-looking statements include information about possible or assumed future results of our business, investment strategies, financial condition, liquidity, results of operations, plans, objectives and our views on domestic and global market conditions (including the mortgage-backed securities, residential and commercial real estate markets). When we use the words “believe,” “expect,” “anticipate,” “estimate,” “plan,” “intend,” “project,” “forecast” or similar expressions and future or conditional verbs such as “will,” “may,” “could,” “should,” and “would,” and any other statement that necessarily depends on future events, we intend to identify forward-looking statements, although not all forward-looking statements may contain such words.

The forward-looking statements are based on our beliefs, assumptions and expectations of our future performance, taking into account all information currently available to us. You should not place undue reliance on these forward-looking statements. These beliefs, assumptions and expectations can change as a result of many possible events or factors, not all of which are known to us. We caution you not to rely unduly on any forward-looking statements and urge you to carefully consider the factors described under the headings "Risk Factors" and "Management’s Discussion and Analysis of Financial Condition and Results of Operations" and elsewhere in this Report and our Annual Report on Form 10-K. If a change occurs, our business, financial condition, liquidity and results of operations may vary materially from those expressed in our forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made. New risks and uncertainties arise over time, and it is not possible for us to predict those events or how they may affect us. Except as required by law, we are not obligated to, and do not intend to, update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Executive Summary

We are a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities (“MBS”) and other mortgage-related assets. Our objective is to provide attractive risk-adjusted returns to our stockholders, primarily through dividends and secondarily through capital appreciation.

As of March 31, 2024, we were invested in:

•residential mortgage-backed securities (“RMBS”) that are guaranteed by a U.S. government agency such as the Government National Mortgage Association (“Ginnie Mae”), or a federally chartered corporation such as the Federal National Mortgage Association (“Fannie Mae” or “FNMA”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac” or “FHLMC”) (collectively “Agency RMBS”);

•commercial mortgage-backed securities ("CMBS") that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Freddie Mac or Fannie Mae (collectively “Agency CMBS”);

•CMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency CMBS”); and

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency RMBS”).

During the periods presented in this Quarterly Report, we also invested in:

•to-be-announced securities forward contracts (“TBAs”) to purchase Agency RMBS;

•U.S. Treasury securities; and

•other real estate-related financing arrangements in the form of unconsolidated ventures.

We continuously evaluate new investment opportunities to complement our current investment portfolio by expanding our target assets and portfolio diversification.

We conduct our business through our wholly-owned subsidiary, IAS Operating Partnership L.P. (the “Operating Partnership”). We are externally managed and advised by our Manager, an indirect wholly-owned subsidiary of Invesco.

We have elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the definition of “Investment Company” under the 1940 Act.

Market Conditions and Impacts

Macroeconomic factors that affect our business include interest rates, interest rate volatility, spread premiums, fiscal and monetary policy, residential and commercial real estate prices, credit availability, the health of the banking system, consumer personal income and spending, corporate earnings, employment conditions, financial conditions and inflation.

Of these macroeconomic factors, government policy initiatives, inflation, interest rates and interest rate volatility had the most direct impacts on our performance and financial condition during the first quarter of 2024. Contributing factors included:

•Financial conditions remained accommodative during the first quarter as credit spreads tightened, equity market valuations increased, and interest rate volatility eased as financial markets reacted favorably despite the higher interest rate environment brought on by shifting expectations for economic growth and monetary policy. Inflation readings were generally flat during the quarter, remaining stubbornly above the Federal Reserve’s 2% inflation target. The headline consumer price index (“CPI”) ended the quarter at 3.5%, up from December’s 3.4%, while CPI (ex. food and energy) fell slightly from 3.9% to 3.8%. Given these relatively high readings, investors' expectations for future inflation have adjusted upward, as Treasury inflation-protected securities breakeven rates increased. The two-year breakeven ended the quarter at 2.72% (up from 2.02% at year-end) and the five-year breakeven ended at 2.44% (up from 2.15%)

•Stronger than expected inflation readings, along with continued evidence of robust economic activity, led to sharply higher interest rates across the maturity spectrum during the quarter. The yield on the two-year Treasury increased by 37 basis points to 4.62%, the yield on the five-year Treasury increased 37 basis points to 4.20% and the yield on the ten-year Treasury finished at 4.19%, up 33 basis points on the quarter. The stronger than expected economic growth and inflation data also led to a dramatic re-pricing of the market’s expectations of future monetary policy. These expectations, as seen the through the Federal Funds futures market, adjusted from projecting over six cuts in the

23

Federal Open Market Committee’s (“FOMC”) benchmark rate during the balance of 2024 to less than three cuts. Further, the market’s expectation for the beginning of the easing cycle shifted from March to July.

•Higher coupon Agency RMBS outperformed Treasuries while coupons lower in the stack underperformed, given a notable decline in interest rate volatility and improvement in supply and demand dynamics in the first quarter of 2024. Despite the sharp increase in interest rates, interest rate volatility fell as market expectations for monetary policy converged with official projections by the FOMC, benefiting valuations in higher coupons. In addition, organic supply remained at very low levels while demand from money managers, commercial banks, and overseas investors broadly outpaced expectations.

•Quantitative tightening continued in the first quarter of 2024, as the Federal Reserve passively reduced the size of their balance sheet through maturities of U.S. Treasuries and paydowns of Agency RMBS. Paydowns of Agency RMBS from the balance sheet added approximately $14.5 billion of net supply to the market each month, well below the Federal Reserve's monthly cap of $35 billion. Although quantitative tightening is anticipated to conclude in the second half of 2024, runoff of the Agency RMBS portion of the balance sheet is expected to continue, with proceeds redeployed into Treasuries.

•Prepayment speeds remained at very low levels given limited housing activity and elevated mortgage rates.

•Premiums on higher coupon specified pool collateral increased modestly given improvement in supply and demand technicals.

•Implied financing via the dollar roll market for TBA investments remained relatively unattractive, as reduced demand from the Federal Reserve and commercial banks negatively impacted fundamentals, while the increase in loan balances worsened the prepayment profile.

•Agency CMBS risk premiums declined over the quarter as new issuance volumes remained relatively low and higher yields helped drive investor demand for fixed-rate bonds.

(1)Swap spreads represent the difference between the fixed rate coupon of an interest rate swap and the yield on a U.S. Treasury security with a similar maturity.

(2)Mortgage spreads represent the difference between the yield on the Agency TBA and the blended average yield of five year and ten year U.S. Treasury securities.

(3)Agency CMBS spreads represent the difference between the yields on new issue Freddie Mac K Certificates and Fannie Mae Delegated Underwriting and Servicing MBS (“DUS”) and a U.S. Treasury security with a similar maturity.

Outlook

Given the increase in market volatility in April, we remain cautious on the near-term outlook for the Agency RMBS sector as the market adjusts to shifting expectations around the timing of monetary policy adjustments. Our recent allocation to fixed rate Agency CMBS reduces our exposure to near-term interest rate volatility while providing attractive returns with favorable funding. Over the longer term, however, the potential normalization of monetary policy and a steeper yield curve should be supportive of Agency RMBS. We believe Agency RMBS investors stand to benefit from attractive valuations, favorable funding and robust liquidity as the macro environment evolves.

(1)Our presentation of TBAs in the table above represents management's view of our investment portfolio and does not reflect how we record TBAs on our condensed consolidated balance sheets under U.S. GAAP. Under U.S. GAAP, we record TBAs that we do not intend to physically settle on the contractual settlement date as derivative financial instruments. We value TBAs on our condensed consolidated balance sheets at net carrying value, which represents the difference between the fair market value and the implied cost basis of the TBAs. Our TBA dollar roll transactions are a form of off-balance sheet financing. For further information on how management evaluates our at-risk leverage, see Non-GAAP Financial Measures below.

As of March 31, 2024, our holdings of 30 year fixed-rate Agency RMBS represented approximately 93% of our total investment portfolio, including TBAs, versus 98% as of December 31, 2023 and March 31, 2023. Our 30 year fixed-rate Agency RMBS holdings as of March 31, 2024, December 31, 2023 and March 31, 2023 consisted of specified pools with coupon distributions as shown in the table below.

Our purchases of Agency RMBS have been primarily focused on specified pools with attractive prepayment profiles. We seek to capitalize on the impact of prepayments on our investment portfolio by purchasing specified pools with characteristics that optimize borrower incentive to prepay for both our premium and discount priced investments. The table below shows the specified pool characteristics of our 30 year fixed-rate Agency RMBS holdings as of March 31, 2024, December 31, 2023 and March 31, 2023.

As of March 31, 2024, our holdings of Agency CMBS represented approximately 5% of our total investment portfolio versus 0% as of December 31, 2023 and March 31, 2023. As of March 31, 2024, our Agency CMBS holdings were comprised of fixed-rate securities with Fannie Mae DUS representing 74% our holdings and Freddie Mac Multifamily Participation Certificates representing 24% of our holdings. We invested in Agency CMBS in the first quarter of 2024 because these securities benefit from prepayment protection characteristics and have an attractive return profile. Further, the hedging costs related to these holdings are economical as they are less sensitive to interest rate risk given prepayment protection and scheduled balloon maturity payments.

As of March 31, 2024, December 31, 2023 and March 31, 2023, our holdings of non-Agency CMBS and non-Agency RMBS represented less than 1% of our total investment portfolio, including TBAs. Approximately 70% of our non-Agency securities were rated double-A (or equivalent) or higher by a nationally recognized statistical rating organization as of March 31, 2024.

In the first quarter of 2024, we received a final distribution from our sole remaining unconsolidated venture. Following this distribution, we no longer have any investments in unconsolidated ventures.

Financing and Other Liabilities

We finance the majority of our investment portfolio through repurchase agreements. Repurchase agreements are generally settled on a short-term basis, usually from one to six months, and bear interest at rates that are expected to move in close relationship to the secured overnight financing rate (“SOFR”).

The following table presents the amount of collateralized borrowings outstanding under repurchase agreements as of the end of each quarter, the average amount outstanding during the quarter and the maximum balance outstanding during the quarter.

Hedging Instruments

We enter into interest rate swap agreements that are designed to mitigate the effects of changes in interest rates for a portion of our borrowings. Under these swap agreements, we generally pay fixed interest rates and receive floating interest rates indexed to SOFR. To a lesser extent, we have also used interest rate swap agreements whereby we make floating interest rate payments indexed to SOFR and receive fixed interest rate payments as part of our overall risk management strategy.

We actively manage our interest rate swap portfolio as the size and composition of our investment portfolio changes. During the three months ended March 31, 2024, we entered into interest rate swaps with a notional amount of $1.3 billion and terminated existing interest rate swaps with a notional amount of $1.1 billion. Daily variation margin payment for interest rate

swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as a realized gain or loss in our condensed consolidated statement of operations.

Capital Activities

As of March 31, 2024, we may sell up to 5,934,691 shares of our common stock from time to time in at-the-market or privately negotiated transactions under our equity distribution agreement with placement agents. During the three months ended March 31, 2024, we sold 365,838 shares of common stock under our equity distribution agreement for proceeds of $3.3 million, net of approximately $43,000 in commissions and fees. During the three months ended March 31, 2023, we sold 2,930,069 shares of common stock under an equity distribution agreement for proceeds of $35.8 million, net of approximately $482,000 in commissions and fees.

For information on dividends declared during the three months ended March 31, 2024 and 2023, see Note 12 - "Stockholders' Equity" of our condensed consolidated financial statements in Part I. Item 1 of this report on Form 10-Q.

During the three months ended March 31, 2024, we did not repurchase any shares of our common stock.

In May 2022, our board of directors approved a share repurchase program for our Series B and Series C Preferred Stock. During the three months ended March 31, 2024, we repurchased and retired 93,347 shares of Series B Preferred Stock and 95,917 shares of Series C Preferred Stock. During the three months ended March 31, 2023, we did not repurchase any shares of preferred stock. As of March 31, 2024, we had authority to repurchase 1,092,650 additional shares of our Series B Preferred Stock and 949,522 additional shares of our Series C Preferred Stock under the current share repurchase program.

Book Value per Common Share

We calculate book value per common share as follows.

Book value per common share	10.08	10.00

Our book value per common share increased 0.8% as of March 31, 2024 compared to December 31, 2023 as our higher coupon Agency RMBS performed well relative to interest rate swap hedges, despite a notable increase in interest rates during the quarter. Strong performance in higher coupons was driven by a meaningful decline in interest rate volatility given market expectations for monetary policy easing in the first half of 2024. Refer to Item 3. “Quantitative and Qualitative Disclosures About Market Risk” for interest rate risk and its impact on fair value.

Interest Income and Average Earning Asset Yields

The table below presents information related to our average earning assets and earning asset yields for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024		2023
Average earning assets (1)	4,972,242		5,245,291
Average earning asset yields (2)	5.52	%	5.28	%

(1)Average balances for each period are based on weighted month-end balances.

(2)Average earning asset yields for the period were calculated by dividing interest income, including amortization of premiums and discounts, by average earning assets based on the amortized cost of the investments. All yields are annualized.

Total average earning assets decreased $273.0 million for the three months ended March 31, 2024 compared to 2023. We maintained similar amounts of leverage during both periods, but modest declines in stockholders' equity resulted in lower average earnings assets for the three months ended March 31, 2024 compared to 2023. Average earning asset yields increased for the three months ended March 31, 2024 compared to 2023 due to our rotation into higher yielding Agency RMBS.

We earned total interest income of $68.6 million for the three months ended March 31, 2024 (March 31, 2023: $69.3 million). Our interest income includes coupon interest and net (premium amortization) discount accretion as shown in the table below.

	Three Months Ended March 31,
$ in thousands	2024	2023
Interest Income
Coupon interest	67,442	69,116
Net (premium amortization) discount accretion	1,141	171
Total interest income	68,583	69,287

Interest income was relatively unchanged for the three months ended March 31, 2024 compared to 2023 as a decrease in average earning assets was largely offset by an increase in average earning asset yields.

Prepayment Speeds

Our RMBS portfolio is subject to inherent prepayment risk primarily driven by changes in interest rates, which impacts the amount of premium and discount on the purchase of these securities that is recognized into interest income. Generally, in an environment of falling interest rates, prepayment speeds will increase as homeowners are more likely to prepay their existing mortgage and refinance into a lower borrowing rate. In an environment of rising interest rates, prepayment speeds will generally decrease as homeowners are not as incentivized to refinance. For Agency RMBS where we do not estimate prepayments, premium amortization and discount accretion are not impacted by prepayments until actual prepayments occur. For those securities on which we do estimate prepayments, expected future prepayment speeds are estimated on a quarterly basis. If the actual prepayment speed during the period is faster than estimated, the amortization on securities purchased at a premium to par value will be accelerated, resulting in lower interest income recognized. Conversely, for securities purchased at a discount to par value, interest income will be reduced in periods where prepayment speeds were slower than expected.

The following table presents net (premium amortization) discount accretion recognized for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024	2023
Agency RMBS	1,136	14
Agency CMBS	5	—

Non-Agency RMBS	(126)	(134)
U.S. Treasury Securities	(1)	—
Net (premium amortization) discount accretion	1,141	171

30

Net discount accretion was $1.1 million for the three months ended March 31, 2024 compared to $171,000 in 2023. The increase in net discount accretion for the three months ended March 31, 2024 compared to 2023 was the result of repositioning our Agency RMBS portfolio into securities with lower book prices and slightly faster prepayment rates.

Our interest income is subject to interest rate risk. Refer to Item 3. "Quantitative and Qualitative Disclosures about Market Risk" for more information relating to interest rate risk and its impact on our operating results.

Interest Expense and Cost of Funds

The table below presents information related to our borrowings and cost of funds for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024		2023
Total average borrowings (1)	4,419,757		4,737,476
Maximum borrowings during the period (2)	4,531,261		4,814,700
Cost of funds (3)	5.57	%	4.20	%

(1)Average borrowings for each period are based on weighted month-end balances.

(2)Amount represents the maximum borrowings at month-end during each of the respective periods.

(3)Average cost of funds is calculated by dividing annualized interest expense including amortization of net deferred gain (loss) on de-designated interest rate swaps by our average borrowings.

Total average borrowings decreased $317.7 million for the three months ended March 31, 2024 compared to 2023. We maintained similar amounts of leverage during both periods, but modest declines in stockholders' equity resulted in lower average borrowings for the three months ended March 31, 2024 compared to 2023. Our average cost of funds increased 137 basis points for the three months ended March 31, 2024 compared to 2023 as the FOMC has raised the Federal Funds target rate from a range of 4.25% to 4.50% as of January 1, 2023 to a range of 5.25% to 5.50% as of March 31, 2024.

The table below presents the components of interest expense for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024	2023
Interest Expense
Interest expense on repurchase agreement borrowings	61,580	54,220
Amortization of net deferred (gain) loss on de-designated interest rate swaps	—	(4,494)
Total interest expense	61,580	49,726

Our interest expense increased $11.9 million for the three months ended March 31, 2024 compared to 2023 as increases in our cost of funds more than offset decreases in our average borrowings.

Our interest expense as reported in our condensed consolidated statement of operations includes amortization of net deferred gains and losses on de-designated interest rate swaps as summarized in the table above. Amortization of net deferred gains on de-designated interest rate swaps decreased our total interest expense by $4.5 million during the three months ended March 31, 2023. Amounts recorded in accumulated other comprehensive income before we discontinued cash flow hedge accounting for our interest rate swaps were reclassified to interest expense on the condensed consolidated statements of operations as interest was accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. As of March 31, 2024 and December 31, 2023, there were no net deferred gains or losses on discontinued cash flow hedges remaining in accumulated other comprehensive income.

Net Interest Income

The table below presents the components of net interest income for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024		2023
Interest income	68,583		69,287
Interest Expense:
Interest expense on repurchase agreement borrowings	61,580		54,220
Amortization of net deferred (gain) loss on de-designated interest rate swaps	—		(4,494)
Total interest expense	61,580		49,726
Net interest income	7,003		19,561
Net interest rate margin	(0.05)	%	1.08	%

Our net interest income, which equals total interest income less total interest expense, totaled $7.0 million for the three months ended March 31, 2024 (March 31, 2023: $19.6 million). The decrease in net interest income and net interest rate margin, which equals the yield on our average assets for the period less the average cost of funds, for three months ended March 31, 2024 compared to 2023 was due to higher interest expense related to increases in the Federal Funds target rate. Our cost of funds is generally more sensitive to changes in interest rates than the yield on our investment portfolio, which is largely comprised of 30 year fixed-rate Agency RMBS.

Gain (Loss) on Investments, net

The table below summarizes the components of gain (loss) on investments, net for the three months ended March 31, 2024 and 2023.

	Three Months Ended March 31,
$ in thousands	2024	2023
Net realized gains (losses) on sale of MBS	(3,222)	(13,765)
Net unrealized gains (losses) on MBS accounted for under the fair value option	(62,473)	65,721
Net unrealized gains (losses) on U.S. Treasury securities	(372)	—
Net realized gains (losses) on U.S. Treasury securities	(86)	—
Total gain (loss) on investments, net	(66,153)	51,956

During the three months ended March 31, 2024, we sold MBS and realized net losses of $3.2 million (March 31, 2023: net losses of $13.8 million). Net realized losses during the three months ended March 31, 2024 reflect sales of lower coupon Agency RMBS with a portion of the proceeds being used to purchase Agency CMBS. Net realized losses during the three months ended March 31, 2023 primarily reflect the repositioning of Agency RMBS coupon allocations and sales of lower yielding Agency RMBS to purchase higher yielding Agency RMBS in an effort to improve the earnings power of the portfolio.

We have elected the fair value option for all of our MBS purchased on or after September 1, 2016. Before September 1, 2016, we had also elected the fair value option for our non-Agency RMBS interest-only securities. Under the fair value option, changes in fair value are recognized in income in the condensed consolidated statements of operations. As of March 31, 2024 and December 31, 2023, $5.0 billion or 99.7% of our MBS were accounted for under the fair value option.

We recorded net unrealized losses on our MBS portfolio accounted for under the fair value option of $62.5 million in the three months ended March 31, 2024 compared to net unrealized gains of $65.7 million in the three months ended March 31, 2023. Net unrealized losses in the three months ended March 31, 2024 resulted from higher interest rates during the quarter, as valuations on fixed-rate securities declined as interest rates rose. Net unrealized gains in the three months ended March 31, 2023 were primarily due to improved Agency RMBS valuations as yields on Treasuries decreased.

We recorded net realized and unrealized losses of $458,000 on U.S. Treasury securities in the three months ended March 31, 2024. We did not hold any U.S. Treasury securities during the three months ended March 31, 2023.

(Increase) Decrease in Provision for Credit Losses

As of March 31, 2024, $15.5 million of our MBS are classified as available-for-sale and subject to evaluation for credit losses (December 31, 2023: $15.7 million). During the three months ended March 31, 2024, we recorded a $39,000 provision

32

for credit losses on a single non-Agency CMBS based on a comparison of the security's amortized cost basis to discounted expected cash flows. We did not record any provisions for credit losses during the three months ended March 31, 2023.

Equity in Earnings (Losses) of Unconsolidated Ventures

For the three months ended March 31, 2024 we recorded equity in losses of unconsolidated ventures of $193,000 (March 31, 2023: equity in earnings of $2,000). We received a final distribution from our sole remaining unconsolidated venture during the first quarter of 2024, and the venture was dissolved in April 2024.

Gain (Loss) on Derivative Instruments, net

We record all derivatives on our condensed consolidated balance sheets at fair value. Changes in the fair value of our derivatives are recorded in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations. Net interest paid or received under our interest rate swaps is also recognized in gain (loss) on derivative instruments, net in our condensed consolidated statements of operations.

The tables below summarize our realized and unrealized gain (loss) on derivative instruments, net for the following periods.

TBAs	(951)	—	509	(442)
Total	(91,900)	54,464	(7,459)	(44,895)

During the three months ended March 31, 2024, we entered into interest rate swaps with a notional amount of $1.3 billion and terminated existing interest rate swaps with a notional amount of $1.1 billion. We recorded net gains of $93.2 million on interest rate swaps for the three months ended March 31, 2024 (March 31, 2023: net losses of $44.5 million) primarily due to changes in forward interest rate expectations.

As of March 31, 2024, we had $4.4 billion of repurchase agreement borrowings with a weighted average remaining maturity of 20 days. We typically refinance each repurchase agreement at market interest rates upon maturity. We use interest rate swaps to manage our exposure to changing interest rates and add stability to interest rate expense.

As of March 31, 2024 and December 31, 2023, we held the following interest rate swaps whereby we pay fixed rate interest and receive floating rate interest based upon SOFR.

$ in thousands	As of March 31, 2024						As of December 31, 2023
Derivative instrument	Notional Amount	Weighted Average Fixed Pay Rate		Weighted Average Floating Receive Rate		Weighted Average Years to Maturity	Notional Amount	Weighted Average Fixed Pay Rate		Weighted Average Floating Receive Rate		Weighted Average Years to Maturity
Interest Rate Swaps	4,265,000	1.17	%	5.34	%	7.2	4,065,000	1.10	%	5.38	%	6.6

We primarily use TBAs that we do not intend to physically settle on the contractual settlement date as an alternative means of investing in and financing Agency RMBS. As of March 31, 2024 and December 31, 2023, we had no investments in TBAs. We recorded $442,000 of net realized and unrealized losses on TBAs during the three months ended March 31, 2023.

33

Other Investment Income (Loss), net

Our other investment income (loss), net during the three months ended March 31, 2023 consisted of foreign currency transaction gains and losses and the reclassification of our foreign currency translation adjustment that was previously recorded in accumulated other comprehensive income related to an unconsolidated venture that was liquidated during the first quarter of 2023.

Expenses

We incurred management fees of $2.9 million for the three months ended March 31, 2024 (March 31, 2023: $3.0 million). Management fees decreased for the three months ended March 31, 2024 compared to the same period in 2023 due to a lower stockholders' equity management fee base. Refer to Note 11 – "Related Party Transactions" of our condensed consolidated financial statements for a discussion of our relationship with our Manager and a description of how our fees are calculated.

Our general and administrative expenses not covered under our management agreement amounted to $1.8 million for the three months ended March 31, 2024 (March 31, 2023: $2.1 million). General and administrative expenses not covered under our management agreement primarily consist of directors and officers insurance, legal costs, accounting, auditing and tax services, filing fees and miscellaneous general and administrative costs.

Gain on Repurchase and Retirement of Preferred Stock

In May 2022, our board of directors approved a share repurchase program for our Series B and Series C Preferred Stock. During the three months ended March 31, 2024, we repurchased and retired 93,347 shares of Series B Preferred Stock and 95,917 shares of Series C Preferred Stock. During the three months ended March 31, 2023, we did not repurchase any shares of preferred stock. Gains on repurchases and retirements of preferred stock represent the difference between the consideration transferred and the carrying value of the preferred stock.

Net Income (Loss) attributable to Common Stockholders

For the three months ended March 31, 2024, our net income attributable to common stockholders was $23.7 million (March 31, 2023: $15.6 million) or $0.49 basic and diluted net income per average share available to common stockholders (March 31, 2023: $0.39). The change in net income attributable to common stockholders was primarily due to (i) net gains on derivative instruments of $93.2 million in the 2024 period compared to net losses on derivative instruments of $44.9 million in the 2023 period; (ii) net losses on investments of $66.2 million in the 2024 period compared to net gains on investments of $52.0 million in the 2023 period; and (iii) a $12.6 million decrease in net interest income.

For further information on the changes in net gain (loss) on derivative instruments, net gain (loss) on investments and changes in net interest income, see preceding discussion under “Gain (Loss) on Derivative Instruments, net”, “Gain (Loss) on Investments, net” and “Net Interest Income”.

Non-GAAP Financial Measures

The table below shows the non-GAAP financial measures we use to analyze our operating results and the most directly comparable U.S. GAAP measures. We believe these non-GAAP measures are useful to investors in assessing our performance as discussed further below.

Non-GAAP Financial Measure	Most Directly Comparable U.S. GAAP Measure
Earnings available for distribution (and by calculation, earnings available for distribution per common share)	Net income (loss) attributable to common stockholders (and by calculation, basic earnings (loss) per common share)
Effective interest expense (and by calculation, effective cost of funds)	Total interest expense (and by calculation, cost of funds)
Effective net interest income (and by calculation, effective interest rate margin)	Net interest income (and by calculation, net interest rate margin)
Economic debt-to-equity ratio	Debt-to-equity ratio

The non-GAAP financial measures used by management should be analyzed in conjunction with U.S. GAAP financial measures and should not be considered substitutes for U.S. GAAP financial measures. In addition, the non-GAAP financial measures may not be comparable to similarly titled non-GAAP financial measures of our peer companies.

34

Earnings Available for Distribution

Our business objective is to provide attractive risk-adjusted returns to our stockholders, primarily through dividends and secondarily through capital appreciation. We use earnings available for distribution as a measure of our investment portfolio’s ability to generate income for distribution to common stockholders and to evaluate our progress toward meeting this objective. We calculate earnings available for distribution as U.S. GAAP net income (loss) attributable to common stockholders adjusted for (gain) loss on investments, net; realized (gain) loss on derivative instruments, net; unrealized (gain) loss on derivative instruments, net; TBA dollar roll income; gain on repurchase and retirement of preferred stock; foreign currency (gains) losses, net and amortization of net deferred (gain) loss on de-designated interest rate swaps.

By excluding the gains and losses discussed above, we believe the presentation of earnings available for distribution provides a consistent measure of operating performance that investors can use to evaluate our results over multiple reporting periods and, to a certain extent, compare to our peer companies. However, because not all of our peer companies use identical operating performance measures, our presentation of earnings available for distribution may not be comparable to other similarly titled measures used by our peer companies. We exclude the impact of gains and losses when calculating earnings available for distribution because (i) when analyzed in conjunction with our U.S. GAAP results, earnings available for distribution provides additional detail of our investment portfolio’s earnings capacity and (ii) gains and losses are not accounted for consistently under U.S. GAAP. Under U.S. GAAP, certain gains and losses are reflected in net income whereas other gains and losses are reflected in other comprehensive income. For example, a portion of our mortgage-backed securities are classified as available-for-sale securities, and we record changes in the valuation of these securities in other comprehensive income on our condensed consolidated balance sheets. We elected the fair value option for our mortgage-backed securities purchased on or after September 1, 2016, and changes in the valuation of these securities are recorded in other income (loss) in our condensed consolidated statements of operations. In addition, certain gains and losses represent one-time events. We may add and have added additional reconciling items to our earnings available for distribution calculation as appropriate.

To maintain our qualification as a REIT, U.S. federal income tax law generally requires that we distribute at least 90% of our REIT taxable income annually, determined without regard to the deduction for dividends paid and excluding net capital gains. We have historically distributed at least 100% of our REIT taxable income. Because we view earnings available for distribution as a consistent measure of our investment portfolio's ability to generate income for distribution to common stockholders, earnings available for distribution is one metric, but not the exclusive metric, that our board of directors uses to determine the amount, if any, and the payment date of dividends on our common stock. However, earnings available for distribution should not be considered as an indication of our taxable income, a guaranty of our ability to pay dividends or as a proxy for the amount of dividends we may pay, as earnings available for distribution excludes certain items that impact our cash needs.

Earnings available for distribution is an incomplete measure of our financial performance and there are other factors that impact the achievement of our business objective. We caution that earnings available for distribution should not be considered as an alternative to net income (determined in accordance with U.S. GAAP) or as an indication of our cash flow from operating activities (determined in accordance with U.S. GAAP), a measure of our liquidity or as an indication of amounts available to fund our cash needs.

(2)A TBA dollar roll is a series of derivative transactions where TBAs with the same specified issuer, term and coupon but different settlement dates are simultaneously bought and sold. The TBA settling in the later month typically prices at a discount to the TBA settling in the earlier month. TBA dollar roll income represents the price differential between the TBA price for current month settlement versus the TBA price for forward month settlement. We include TBA dollar roll income in earnings available for distribution because it is the economic equivalent of interest income on the underlying Agency RMBS, less an implied financing cost, over the forward settlement period. TBA dollar roll income is a component of gain (loss) on derivative instruments, net on our condensed consolidated statements of operations.

(3)Foreign currency gains (losses), net includes foreign currency transaction gains and losses and the reclassification of currency translation adjustments that were previously recorded in accumulated other comprehensive income and is included in other investment income (loss), net on the condensed consolidated statements of operations.

Earnings available for distribution decreased during the three months ended March 31, 2024 compared to the same period in 2023 due to lower effective net interest income. See below for details on the change in effective net interest income.

Effective Interest Expense / Effective Cost of Funds / Effective Net Interest Income / Effective Interest Rate Margin

We calculate effective interest expense (and by calculation, effective cost of funds) as U.S. GAAP total interest expense adjusted for contractual net interest income (expense) on our interest rate swaps that is recorded as gain (loss) on derivative instruments, net and the amortization of net deferred gains (losses) on de-designated interest rate swaps that is recorded as interest expense. We view our interest rate swaps as an economic hedge against increases in future market interest rates on our borrowings. We add back the net payments or receipts on our interest rate swap agreements to our total U.S. GAAP interest expense because we use interest rate swaps to add stability to interest expense. We exclude the amortization of net deferred gains (losses) on de-designated interest rate swaps from our calculation of effective interest expense because we do not consider the amortization a current component of our borrowing costs.

We calculate effective net interest income (and by calculation, effective interest rate margin) as U.S. GAAP net interest income adjusted for contractual net interest income (expense) on our interest rate swaps that is recorded as gain (loss) on derivative instruments, net and amortization of net deferred gains (losses) on de-designated interest rate swaps that is recorded as interest expense.

We believe the presentation of effective interest expense, effective cost of funds, effective net interest income and effective interest rate margin measures, when considered together with U.S. GAAP financial measures, provides information that is useful to investors in understanding our borrowing costs and operating performance.

The following table reconciles total interest expense to effective interest expense and cost of funds to effective cost of funds for the following periods.

Effective interest expense	16,293	1.47	%	(244)	(0.02)	%

Our effective interest expense and effective cost of funds increased in the three months ended March 31, 2024 compared to the same period in 2023 due to higher U.S. GAAP interest expense driven by increases in the Federal Funds target rate and decreases in contractual net interest income on interest rate swaps.

In addition to changes caused by the underlying floating rate index, the amount of contractual net interest income or expense on interest swaps that we recognize may change materially from period to period based on changes in the size and

37

composition of our interest rate swap portfolio, which are generally broadly aligned with changes in our repurchase agreement borrowings. See preceding discussion under “Gain (Loss) on Derivative Instruments, net” for details of our interest rate swap portfolio as of March 31, 2024 and December 31, 2023.

Our effective net interest income and effective interest rate margin decreased in the three months ended March 31, 2024 compared to the same period in 2023 due to higher U.S. GAAP interest expense driven by increases in the Federal Funds target rate and decreases in contractual net interest income on interest rate swaps.

Economic Debt-to-Equity Ratio

The tables below show the allocation of our stockholders' equity to our target assets, our debt-to-equity ratio, and our economic debt-to-equity ratio as of March 31, 2024 and December 31, 2023. Our debt-to-equity ratio is calculated in accordance with U.S. GAAP and is the ratio of total debt to total stockholders' equity. As of March 31, 2024, approximately 88% of our equity is allocated to Agency RMBS.

We present an economic debt-to-equity ratio, a non-GAAP financial measure of leverage that considers the impact of the off-balance sheet financing of our investments in TBAs that are accounted for as derivative instruments under U.S. GAAP. We include our TBAs at implied cost basis in our measure of leverage because a forward contract to acquire Agency RMBS in the TBA market carries similar risks to Agency RMBS purchased in the cash market and funded with on-balance sheet liabilities. Similarly, a contract for the forward sale of Agency RMBS has substantially the same effect as selling the underlying Agency RMBS and reducing our on-balance sheet funding commitments. We believe that presenting our economic debt-to-equity ratio, when considered together with our U.S. GAAP financial measure of debt-to-equity ratio, provides information that is useful to investors in understanding how management evaluates our at-risk leverage and gives investors a comparable statistic to those of other mortgage REITs who also invest in TBAs and present a similar non-GAAP measure of leverage.

Liquidity and Capital Resources

Liquidity is a measure of our ability to meet potential cash requirements, including ongoing commitments to pay dividends, fund investments, repay borrowings and fund other general business needs. Our primary sources of funds for liquidity consist of the net proceeds from our common and preferred equity offerings, net cash provided by operating activities, proceeds from repurchase agreements and other financing arrangements and future issuances of equity and/or debt securities.

We currently believe that we have sufficient liquidity and capital resources available for the acquisition of additional investments, repayments on borrowings, margin requirements and the payment of cash dividends as required for continued qualification as a REIT. We generally maintain liquidity to pay down borrowings under repurchase arrangements to reduce borrowing costs and otherwise efficiently manage our long-term investment capital. Because the level of these borrowings can be adjusted on a daily basis, the level of cash and cash equivalents carried on our condensed consolidated balance sheets is significantly less important than our potential liquidity available under borrowing arrangements or through the sale of liquid investments. However, there can be no assurance that we will maintain sufficient levels of liquidity to meet any margin calls.

We held cash, cash equivalents and restricted cash of $200.5 million as of March 31, 2024 (March 31, 2023: $228.9 million). Our cash, cash equivalents and restricted cash change due to normal fluctuations in cash balances related to the timing of principal and interest payments, repayments of debt, and asset purchases and sales. Our operating activities provided net cash of approximately $57.5 million for the three months ended March 31, 2024 (March 31, 2023: $67.2 million).

Our investing activities provided net cash of $37.1 million in the three months ended March 31, 2024 compared to net cash used by investing activities of $696.9 million in the three months ended March 31, 2023. Our primary source of cash from investing activities for the three months ended March 31, 2024 was proceeds from sales of MBS of $296.5 million and proceeds from sales of U.S. Treasury securities of $10.8 million (March 31, 2023: $783.9 million from the sales of MBS). We also generated $71.2 million from principal payments of MBS during the three months ended March 31, 2024 (March 31, 2023: $61.1 million) and received cash of $48.7 million to settle derivative contracts in the three months ended March 31, 2024 (March 31, 2023: net cash used of $91.9 million). We used cash of $390.4 million to purchase MBS during the three months ended March 31, 2024 (March 31, 2023: $1.4 billion to purchase MBS).

Our financing activities used net cash of $92.7 million for the three months ended March 31, 2024 compared to net cash provided by financing activities of $579.8 million in the three months ended March 31, 2023. During the three months ended March 31, 2024, we used cash for net repayments on our repurchase agreements of $64.4 million (March 31, 2023: net cash

40

provided of $579.9 million). We also used cash of $25.0 million for the three months ended March 31, 2024 to pay dividends (March 31, 2023: $31.0 million). Proceeds from issuance of common stock provided $3.3 million for the three months ended March 31, 2024 (March 31, 2023: $35.8 million).

As of March 31, 2024, the average margin requirement (weighted by borrowing amount), or the haircut, under our repurchase agreements was 4.6% for Agency RMBS and 5.0% for Agency CMBS. The haircuts ranged from a low of 3% to a high of 5% for Agency RMBS and a low of 4% to a high of 6% for Agency CMBS. Declines in the value of our securities portfolio can trigger margin calls by our lenders under our repurchase agreements. An event of default or termination event may give our counterparties the option to terminate all repurchase transactions outstanding with us and require any amount due from us to the counterparties to be payable immediately.

Effects of Margin Requirements, Leverage and Credit Spreads

Our securities have values that fluctuate according to market conditions and the market value of our securities will decrease as prevailing interest rates or credit spreads increase. When the value of the securities pledged to secure a repurchase loan decreases to the point where the positive difference between the collateral value and the loan amount is less than the haircut, our lenders may issue a “margin call”, which means that the lender will require us to pay cash or pledge additional collateral. Under our repurchase facilities, our lenders have full discretion to determine the value of the securities we pledge to them. Most of our lenders will value securities based on recent trades 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 and increased collateral requirements in the ordinary course of our business. In seeking to effectively manage the margin requirements established by our lenders, we maintain a position of cash and unpledged securities. 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 securities. If interest rates increase as a result of a yield curve shift or for another reason 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 seek 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 or increased collateral requirements. 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 and increased collateral requirements but that also allows us to be substantially invested in securities. 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 would force us to liquidate assets into unfavorable market conditions and harm our results of operations and financial condition.

We are subject to financial covenants in connection with our lending, derivatives and other agreements we enter into in the normal course of our business. We intend to operate in a manner which complies with all of our financial covenants. Our lending and derivative agreements provide that we may be declared in default of our obligations if our leverage ratio exceeds certain thresholds and we fail to maintain stockholders’ equity or market value above certain thresholds over specified time periods.

Forward-Looking Statements Regarding Liquidity

As of March 31, 2024, we held $4.6 billion of Agency securities that are financed by repurchase agreements. We also had approximately $390.7 million of unencumbered investments and unrestricted cash of $59.9 million as of March 31, 2024. As of March 31, 2024, our known contractual obligations primarily consisted of $4.4 billion of repurchase agreement borrowings with a weighted average remaining maturity of 20 days. We generally intend to refinance the majority of our repurchase agreement borrowings at market rates upon maturity. Repurchase agreement borrowings that are not refinanced upon maturity are typically repaid through the use of cash on hand or proceeds from sales of securities.

Based upon our current portfolio and existing borrowing arrangements, we believe that cash flow from operations and available borrowing capacity will be sufficient to enable us to meet anticipated short-term (one year or less) liquidity requirements to fund our investment activities, pay fees under our management agreement, fund our required distributions to stockholders and fund other general corporate expenses.

Our ability to meet our long-term (greater than one year) liquidity and capital resource requirements will be subject to obtaining additional debt financing. We may increase our capital resources by obtaining long-term credit facilities or through public or private offerings of equity or debt securities, possibly including classes of preferred stock, common stock, senior or subordinated notes and convertible notes. Such financing will depend on market conditions for capital raises and our ability to

41

invest such offering proceeds. If we are unable to renew, replace or expand our sources of financing on substantially similar terms, it may have an adverse effect on our business and results of operations.

Exposure to Financial Counterparties

We finance a substantial portion of our investment portfolio through repurchase agreements. Under these agreements, we pledge assets from our investment portfolio as collateral. Additionally, certain counterparties may require us to provide cash collateral in the event the market value of the assets declines to maintain a contractual repurchase agreement collateral ratio. If a counterparty were to default on its obligations, we would be exposed to potential losses to the extent the fair value of collateral pledged by us to the counterparty including any accrued interest receivable on such collateral exceeded the amount loaned to us by the counterparty plus interest due to the counterparty.

As of March 31, 2024, no counterparty held collateral that exceeded the amounts borrowed under the related repurchase agreements by more than $39.3 million, or 5% of our stockholders' equity. The following table summarizes our exposure to counterparties by geographic concentration as of March 31, 2024. The information is based on the geographic headquarters of the counterparty or counterparty's parent company. However, our repurchase agreements are denominated in U.S. dollars.

Dividends

To maintain our qualification as a REIT, U.S. federal income tax law generally requires that we distribute at least 90% of our REIT taxable income annually, determined without regard to the deduction for dividends paid and excluding net capital gains. We must pay tax at regular corporate rates to the extent that we annually distribute less than 100% of our REIT 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 repurchase agreements and other debt payable. If our cash available for distribution is less than our REIT taxable income, we could be required to sell assets or borrow funds to make 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 discussed above, our distribution requirements are based on REIT taxable income rather than U.S. GAAP net income. The primary differences between our REIT taxable income and U.S. GAAP net income are: (i) unrealized gains and losses on investments that we have elected the fair value option for that are included in current U.S. GAAP income but are excluded from REIT taxable income until realized or settled; (ii) gains and losses on derivative instruments that are included in current U.S. GAAP net income but are excluded from REIT taxable income until realized; and (iii) temporary differences related to amortization of premiums and discounts on investments. For additional information regarding the characteristics of our dividends, refer to Note 12 – "Stockholders' Equity" of our annual report on Form 10-K for the year ended December 31, 2023.

Unrelated Business Taxable Income

We have not engaged in transactions that would result in a portion of our income being treated as unrelated business taxable income.

Other Matters

We believe that we satisfied each of the asset tests in Section 856(c)(4) of the Internal Revenue Code of 1986, as amended (the "Code") for the period ended March 31, 2024, and that our proposed method of operation will permit us to satisfy the asset tests, gross income tests, and distribution and stock ownership requirements for our taxable year that will end on December 31, 2024.

At all times, we intend to conduct our business so that neither we nor our Operating Partnership nor the subsidiaries of our Operating Partnership are required to register as an investment company under the 1940 Act. If we were required to register as an investment company, then our use of leverage would be substantially reduced. Because we are a holding company that conducts our business through our Operating Partnership and the Operating Partnership’s wholly-owned or majority-owned

42

subsidiaries, the securities issued by these subsidiaries that are excepted from the definition of "investment company" under Section 3(c)(1) or Section 3(c)(7) of the 1940 Act, together with any other investment securities the Operating Partnership may own, may not have a combined value in excess of 40% of the value of the Operating Partnership’s total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis, which we refer to as the 40% test. This requirement limits the types of businesses in which we are permitted to engage in through our subsidiaries. In addition, we believe neither we nor the Operating Partnership are considered an investment company under Section 3(a)(1)(A) of the 1940 Act because they do not engage primarily or hold themselves out as being engaged primarily in the business of investing, reinvesting or trading in securities. Rather, through the Operating Partnership’s wholly-owned or majority-owned subsidiaries, we and the Operating Partnership are primarily engaged in the non-investment company businesses of these subsidiaries. IAS Asset I LLC and certain of the Operating Partnership’s other subsidiaries that we may form in the future rely upon the exclusion from the definition of "investment company" under the 1940 Act provided by Section 3(c)(5)(C) of the 1940 Act, which is available for entities "primarily engaged in the business of purchasing or otherwise acquiring mortgages and other liens on and interests in real estate." This exclusion generally requires that at least 55% of each subsidiary’s portfolio be comprised of qualifying assets and at least 80% be comprised of qualifying assets and real estate-related assets (and no more than 20% comprised of miscellaneous assets). We calculate that as of March 31, 2024, we conducted our business so as not to be regulated as an investment company under the 1940 Act.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The primary components of our market risk are related to interest rate, principal prepayment and market value. While we do not seek to avoid risk completely, we believe the risk can be quantified from historical experience and we seek to actively manage that risk, to earn sufficient compensation to justify taking those risks and to maintain capital levels consistent with the risks we undertake.

For additional discussion of market risk, see Part I. Item 1 - Risk Factors of our annual report on Form 10-K for the year ended December 31, 2023.

Interest Rate Risk

Interest rate risk is highly sensitive to many factors, including governmental, monetary 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 our investments and our repurchase agreements. Our repurchase agreements are typically short-term in nature and are periodically refinanced at current market rates. We typically mitigate this interest rate risk by utilizing derivative contracts, primarily interest rate swap agreements.

Interest Rate Effect 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 interest rate hedging activities. During periods of rising interest rates, the borrowing costs associated with our investments tend to increase while the income earned on our fixed interest rate investments may remain substantially unchanged. This increase in borrowing costs results in the narrowing of the net interest spread between the related assets and borrowings and may even result in losses. Further, defaults could increase and result in credit losses to us, which could adversely affect our liquidity and operating results. Such delinquencies or defaults could also have an adverse effect on the spread between interest-earning assets and interest-bearing liabilities.

Hedging techniques are partly based on assumed levels of prepayments of our RMBS. If prepayments are slower or faster than assumed, the life of the RMBS will be longer or shorter, which would reduce the effectiveness of any hedging strategies we may use and may cause losses on such transactions. Hedging strategies involving the use of derivative securities are highly complex and may produce volatile returns.

Interest Rate Effects on Fair Value

Another component of interest rate risk is the effect that changes in interest rates will have on the market value of the assets that we acquire. We face the risk that the market value of our assets will increase or decrease at different rates than those of our liabilities, including our hedging instruments.

We primarily assess our interest rate risk by estimating the duration of our assets and the duration of our liabilities. Duration measures the market price volatility of financial instruments as interest rates change. We generally calculate duration using various financial models and empirical data. Different models and methodologies can produce different duration values for the same securities.

The impact of changing interest rates on fair value can change significantly when interest rates change materially. Therefore, the volatility in the fair value of our assets could increase significantly in the event interest rates change materially. In addition, other factors impact the fair value of our interest rate-sensitive investments and hedging instruments, such as the

43

shape of the yield curve, market expectations as to future interest rate changes and other market conditions. Accordingly, changes in actual interest rates may have a material adverse effect on us.

Spread Risk

We refer to the difference between interest rates on our investments and interest rates on risk free instruments as spreads. We employ a variety of spread risk management techniques that seek to mitigate the influences of spread changes on our book value and our liquidity to help us achieve our investment objectives. The yield on our investments changes over time due to the level of risk free interest rates, the creditworthiness of the security, and the price of the perceived risk. The change in the market yield of our interest rate hedges also changes primarily with the level of risk free interest rates. We manage spread risk through careful asset selection, sector allocation, regulating our portfolio value-at-risk, and seeking to maintain adequate liquidity. Changes in spreads impact our book value and our liquidity and could cause us to sell assets and to change our investment strategy to maintain liquidity and preserve book value.

Inflation, financial conditions, monetary policy initiatives, interest rates and interest rate volatility have impacted and may continue to impact credit spreads.

Prepayment Risk

As we receive prepayments of principal on our investments, premiums or discounts on these investments are amortized against interest income. In general, an increase in prepayment rates will accelerate the amortization of purchase premiums, thereby reducing the interest income earned on the investments. Conversely, discounts on such investments are accreted into interest income. In general, an increase in prepayment rates will accelerate the accretion of purchase discounts, thereby increasing the interest income earned on the investments.

Uncertainty regarding the rate of inflation, fiscal and monetary policy initiatives, elevated interest rate volatility and other factors have made it more difficult to predict prepayment levels for the securities in our portfolio. As a result, it is possible that realized prepayment behavior will be materially different from our expectations.

Extension Risk

We compute the projected weighted average life of our investments based upon assumptions regarding the rate at which the borrowers will prepay the underlying mortgages. In general, when a fixed-rate or hybrid adjustable-rate security is acquired with borrowings, we may, but are not required to, enter into an interest rate swap agreement or other hedging instrument that effectively fixes our borrowing costs for a period close to the anticipated average life of the fixed-rate portion of the related assets. This strategy is designed to protect us from rising interest rates, because the borrowing costs are fixed for the duration of the fixed-rate portion of the related target asset.

However, if prepayment rates decrease in a rising interest rate environment, then the life of the fixed-rate portion of the related assets could extend beyond the term of the swap agreement or other hedging instrument. This could have a negative impact on our results from operations, as borrowing costs would no longer be fixed after the end of the hedging instrument, while the income earned on the hybrid adjustable-rate assets would remain fixed. This situation may also cause the market value of our hybrid adjustable-rate assets to decline, with little or no offsetting gain from the related hedging transactions. In extreme situations, we may be forced to sell assets to maintain adequate liquidity, which could cause us to incur losses.

Market Risk

Market Value Risk

Our available-for-sale securities are reflected at their estimated fair value with unrealized gains and losses excluded from earnings and reported in other comprehensive income under ASC Topic 320. The estimated fair value of these securities fluctuates primarily due to changes in interest rates and other factors. Generally, in a rising interest rate environment, the estimated fair value of these securities would be expected to decrease; conversely, in a falling interest rate environment, the estimated fair value of these securities would be expected to increase.

Pandemics and other widespread crises, including any related fiscal or monetary policy responses, may cause extreme volatility and illiquidity in fixed income markets. The amount of financing we receive under our repurchase agreements is directly related to our counterparties’ valuation of our assets that collateralize the outstanding repurchase agreement financing. When these or similar market conditions are present, margin call risk is elevated and our operating results and financial condition may be materially impacted.

The sensitivity analysis table presented below shows the estimated impact of an instantaneous parallel shift in the yield curve, up and down 50 and 100 basis points, on the market value of our interest rate-sensitive investments and net interest income, including net interest paid or received under interest rate swaps, as of March 31, 2024 and December 31, 2023, assuming a static portfolio and constant financing and credit spreads. When evaluating the impact of changes in interest rates,

44

prepayment assumptions and principal reinvestment rates are adjusted based on our Manager’s expectations. The analysis presented utilized assumptions, models and estimates of our Manager based on our Manager’s judgment and experience.

	As of March 31, 2024				As of December 31, 2023
Change in Interest Rates	Percentage Change in Projected Net Interest Income		Percentage Change in Projected Portfolio Value		Percentage Change in Projected Net Interest Income		Percentage Change in Projected Portfolio Value
+1.00%	0.05	%	(0.51)	%	(1.04)	%	(0.76)	%
+0.50%	0.10	%	(0.13)	%	(0.41)	%	(0.23)	%
-0.50%	(0.29)	%	(0.22)	%	0.27	%	(0.13)	%
-1.00%	(0.52)	%	(0.87)	%	0.93	%	(0.68)	%

Certain assumptions have been made in connection with the calculation of the information set forth in the foregoing interest rate sensitivity table and, as such, there can be no assurance that assumed events will occur or that other events will not occur that would affect the outcomes. The interest rate scenarios assume interest rates as of March 31, 2024 and December 31, 2023. Furthermore, while the analysis reflects the estimated impact of interest rate increases and decreases on a static portfolio, we actively manage the size and composition of our investment and swap portfolios, which can result in material changes to our interest rate risk profile. When applicable, our scenario analysis assumes a floor of 0% for U.S. Treasury yields and, to be consistent, we also apply a floor of 0% for all related funding costs.

The information set forth in the interest rate sensitivity table above and all related disclosures constitutes 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.

Real Estate Risk

Residential and commercial property values are subject to volatility and may be adversely affected by a number of factors, 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 the supply of housing stock or other property sectors); changes or continued weakness in specific industry segments; construction quality, age and design; demographic factors; and retroactive changes to building or similar codes. In addition, decreases in property values reduce the value of the collateral and the potential proceeds available to a borrower to repay our loans, which could also cause us to suffer losses.

Credit Risk

We retain the risk of potential credit losses on all of our residential and commercial mortgage investments. We seek to manage this risk through our pre-acquisition due diligence process. In addition, we re-evaluate the credit risk inherent in our investments on a regular basis pursuant to fundamental considerations such as GDP, unemployment, interest rates, retail sales, store closings/openings, corporate earnings, housing inventory, affordability and regional home price trends. We also review key loan credit metrics including, but not limited to, payment status, current loan-to-value ratios, current borrower credit scores and debt yields. These characteristics assist in determining the likelihood and severity of loan loss as well as prepayment and extension expectations. We then perform structural analysis under multiple scenarios to establish likely cash flow profiles and credit enhancement levels relative to collateral performance projections. This analysis allows us to quantify our opinions of credit quality and fundamental value, which are key drivers of portfolio management decisions.

Given deteriorating fundamentals and tightening lending conditions, borrowers may experience difficulties meeting their obligations and refinancing loans upon scheduled maturities. Loans may experience increasing delinquency levels and eventual defaults, which could impact the performance of our mortgage-backed securities. We also expect credit rating agencies to continue to reassess transactions negatively impacted by these adverse changes, which may result in our investments being downgraded.

Risk Management

To the extent consistent with maintaining our REIT qualification, we seek to manage risk exposure to protect our investment portfolio against the effects of major interest rate changes. We generally seek to manage this risk by:

•monitoring and adjusting, if necessary, the reset index and interest rate related to our target assets and our financings;

•attempting to structure our financing agreements to have a range of different maturities, terms, amortizations and interest rate adjustment periods;

•exploring options to obtain financing arrangements that are not marked to market;

45

•using hedging instruments, primarily interest rate swap agreements but also financial futures, options, interest rate cap agreements, floors and forward sales to adjust the interest rate sensitivity of our target assets and our borrowings; and

•actively managing, on an aggregate basis, the interest rate indices, interest rate adjustment periods, and gross reset margins of our target assets and the interest rate indices and adjustment periods of our financings.

ITEM 4.     CONTROLS AND PROCEDURES.

Our management is responsible for establishing and maintaining disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act.

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 March 31, 2024. 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 timely decisions regarding required disclosure.

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.

Changes in Internal Control over Financial Reporting    

There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the quarter ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization and Business Operations

Invesco Mortgage Capital Inc. (the “Company” or “we”) is a Maryland corporation primarily focused on investing in, financing and managing mortgage-backed securities ("MBS”) and other mortgage-related assets.

As of March 31, 2024, we were invested in:

•residential mortgage-backed securities (“RMBS”) that are guaranteed by a U.S. government agency such as the Government National Mortgage Association (“Ginnie Mae”), or a federally chartered corporation such as the Federal National Mortgage Association (“Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“Freddie Mac”) (collectively “Agency RMBS”);

•commercial mortgage-backed securities (“CMBS”) that are guaranteed by a U.S. government agency such as Ginnie Mae or a federally chartered corporation such as Fannie Mae or Freddie Mac (collectively "Agency CMBS");

•CMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency CMBS”); and

•RMBS that are not guaranteed by a U.S. government agency or a federally chartered corporation (“non-Agency RMBS”).

During the periods presented in these condensed consolidated financial statements, we also invested in U.S. Treasury securities and real estate-related financing arrangements in the form of unconsolidated ventures.

We conduct our business through IAS Operating Partnership L.P. (the “Operating Partnership”) and have one operating segment. We are externally managed and advised by Invesco Advisers, Inc. (our “Manager”), a registered investment adviser and an indirect, wholly-owned subsidiary of Invesco Ltd. (“Invesco”), a leading independent global investment management firm.

We elected to be taxed as a real estate investment trust (“REIT”) for U.S. federal income tax purposes under the provisions of the Internal Revenue Code of 1986. To maintain our REIT qualification, we are generally required to distribute at least 90% of our REIT taxable income to our stockholders annually. We operate our business in a manner that permits our exclusion from the “Investment Company” definition under the Investment Company Act of 1940, as amended (the “1940 Act”).

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2023.

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed securities and allowances for credit losses. Actual results may differ from those estimates.

Significant Accounting Policies

There have been no changes to our accounting policies included in Note 2 to the consolidated financial statements of our Annual Report on Form 10-K for the year ended December 31, 2023.

Borrowings

Borrowings

We finance the majority of our investment portfolio through repurchase agreements. Our repurchase agreements bear interest at a contractually agreed upon rate and generally have maturities ranging from one to six months. We account for our repurchase agreements as secured borrowings since we maintain effective control of the financed assets. Our repurchase agreements are subject to certain financial covenants. We were in compliance with all of these covenants as of March 31, 2024.

The following tables summarize certain characteristics of our borrowings as of March 31, 2024 and December 31, 2023. Refer to Note 7 - "Collateral Positions" for collateral pledged and held under our repurchase agreements.

Collateral Positions

Collateral Positions

The following table summarizes the fair value of collateral that we pledged and held under our repurchase agreements, and interest rate swaps as of March 31, 2024 and December 31, 2023. Refer to Note 2 - "Summary of Significant Accounting Policies - Fair Value Measurements" of our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023 for a description of how we determine fair value. Agency RMBS and Agency CMBS collateral pledged is included in mortgage-backed securities on our condensed consolidated balance sheets. Cash collateral pledged on centrally cleared interest rate swaps is classified as restricted cash on our condensed consolidated balance sheets.

Cash collateral held that is not restricted for use is included in cash and cash equivalents on our condensed consolidated balance sheets and the liability to return the collateral is included in collateral held payable. Non-cash collateral held is only recognized if the counterparty defaults or if we sell the pledged collateral. As of March 31, 2024 and December 31, 2023, we did not recognize any non-cash collateral held on our condensed consolidated balance sheets.

Repurchase Agreements

Collateral pledged with our repurchase agreement counterparties is segregated in our books and records. The repurchase agreement counterparties have the right to resell and repledge the collateral posted but have the obligation to return the pledged collateral, or substantially the same collateral if agreed to by us, upon maturity of the repurchase agreement. Under the repurchase agreements, the respective lender retains the contractual right to mark the underlying collateral to fair value. We would be required to provide additional collateral to fund margin calls if the value of pledged assets declined. We intend to maintain a level of liquidity that will enable us to meet margin calls.

The ratio of our total repurchase agreements collateral pledged to our total repurchase agreements outstanding was 105% as of March 31, 2024 (December 31, 2023: 106%) based on the fair value of the securities as reported in our condensed consolidated balance sheets.

Interest Rate Swaps

As of March 31, 2024 and December 31, 2023, all of our interest rate swaps were centrally cleared by a registered clearing organization such as the Chicago Mercantile Exchange (“CME”) and LCH Limited (“LCH”) through a Futures Commission Merchant (“FCM”). We are required to pledge initial margin and daily variation margin for our centrally cleared interest rate swaps that is based on the fair value of our contracts as determined by our FCM. Collateral pledged with our FCM is segregated in our books and records and can be in the form of cash or securities. Daily variation margin for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral and is recorded as gain (loss) on

derivative instruments, net in our condensed consolidated statements of operations. Certain of our FCM agreements include cross default provisions.

Refer to Note 7 - "Collateral Positions" for further information regarding our collateral pledged to and received from our derivative counterparties.

Interest Rate Swaps

At each settlement date, we typically refinance each repurchase agreement at the market interest rate at that time. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposures to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps as part of our interest rate risk management strategy. Under the terms of the majority of our interest rate swap contracts, we make fixed-rate payments to a counterparty in exchange for the receipt of floating-rate amounts over the life of the agreements without exchange of the underlying notional amount. To a lesser extent, we also enter into interest rate swap contracts whereby we make floating-rate payments to a counterparty in exchange for the receipt of fixed-rate amounts as part of our overall risk management strategy.

Amounts recorded in accumulated other comprehensive income before we discontinued cash flow hedge accounting for our interest rate swaps were reclassified to interest expense on the condensed consolidated statements of operations as interest was accrued and paid on the related repurchase agreements over the remaining life of the interest rate swap agreements. We reclassified $4.5 million as a decrease to interest expense during the three months ended March 31, 2023. As of March 31, 2024 and December 31, 2023, there were no gains or losses on discontinued cash flow hedges remaining in accumulated other comprehensive income.

As of March 31, 2024 and December 31, 2023, we had interest rate swaps whereby we pay interest at a fixed rate and receive floating interest based on the secured overnight financing rate (“SOFR”) with the following maturities outstanding.

Offsetting Assets and Liabilities

Offsetting Assets and Liabilities

Certain of our repurchase agreements and derivative transactions are governed by underlying agreements that generally provide for a right of offset under master netting arrangements (or similar agreements) in the event of default or in the event of bankruptcy of either party to the transactions. Assets and liabilities subject to such arrangements are presented on a gross basis in the condensed consolidated balance sheets.

The following tables present information about the assets and liabilities that are subject to master netting arrangements (or similar agreements) and can potentially be offset on our condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023. The daily variation margin payment for centrally cleared interest rate swaps is characterized as settlement of the derivative itself rather than collateral. Our derivative asset of $131,000 as of March 31, 2024 (December 31, 2023: asset of $939,000) related to centrally cleared interest rate swaps is not included in the table below as a result of this characterization of daily variation margin.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

A three-level valuation hierarchy exists for disclosure of fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect our market assumptions. The three levels are defined as follows:

•Level 1 Inputs – Quoted prices for identical instruments in active markets.

•Level 2 Inputs – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

•Level 3 Inputs – Instruments with primarily unobservable value drivers.

The following tables present our assets and liabilities measured at fair value on a recurring basis.

(2)For more information on U.S. Treasury securities, refer to Note 5 - “U.S. Treasury Securities”.

(3)Our investment in an unconsolidated venture was valued using the net asset value (“NAV”) as a practical expedient and was not subject to redemption, although investors could sell or transfer their interest at the approval of the general partner of the underlying funds. The unconsolidated venture made its final distribution in the first quarter of 2024.

The following table presents the carrying value and estimated fair value of our financial instruments that are not carried at fair value on the condensed consolidated balance sheets as of March 31, 2024 and December 31, 2023.

Total	4,393,908	4,393,901	4,458,695	4,458,662

The estimated fair value of repurchase agreements is a Level 3 fair value measurement based on an expected present value technique. This method discounts future estimated cash flows using rates we determined best reflect current market interest rates that would be offered for repurchase agreements with similar characteristics and credit quality.

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 we delegate to it. Under the terms of our management agreement, our Manager and its affiliates provide us with our management team, including our officers and appropriate support personnel. Each of our officers is an employee of our Manager or one of its affiliates. We do not have any employees. Our Manager is not obligated to dedicate any of its employees exclusively to us, nor is our Manager obligated to dedicate any specific portion of time to our business. The costs of support personnel provided by our Manager for the three months ended March 31, 2024 reimbursed or reimbursable by us were $231,000 (March 31, 2023: $409,000).

Management Fee

We pay our Manager a fee equal to 1.50% of our stockholders' equity per annum. For purposes of calculating the management fee, stockholders' equity is calculated as average month-end stockholders' equity for the prior calendar quarter as determined in accordance with U.S. GAAP. Stockholders' equity may exclude one-time events due to changes in U.S. GAAP and certain non-cash items upon approval by a majority of our independent directors.

We do not pay any management fees on our investments in unconsolidated ventures that are managed by an affiliate of our Manager.

Expense Reimbursement

We are required to reimburse our Manager for operating expenses incurred on our behalf, including directors and officers insurance, accounting services, auditing and tax services, legal services, filing fees, and miscellaneous general and administrative costs. Our reimbursement obligation is not subject to any dollar limitation.

Accounting Policies [Abstract]

Basis of Presentation

Certain disclosures included in our Annual Report on Form 10-K are not required to be included on an interim basis in our quarterly reports on Form 10-Q. We have condensed or omitted these disclosures. Therefore, this Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2023.

Consolidation

Our condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and consolidate the financial statements of the Company and its controlled subsidiaries. All significant intercompany transactions, balances, revenues and expenses are eliminated upon consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for a fair statement of our financial condition and results of operations for the periods presented.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Examples of estimates include, but are not limited to, estimates of the fair values of financial instruments, interest income on mortgage-backed securities and allowances for credit losses. Actual results may differ from those estimates.
