Summary of Second Quarter 2026 Results The Company's total economic return for the second quarter of 2026 of $0.81 per common share was comprised of an increase in book value of $0.30 per common share and dividends declared of $0.51 per common share. The increase in book value per common share was primarily comprised of a net gain of $102 million on the Company's investment portfolio, net of hedges. The fair value of the Company's Agency MBS benefited from spread tightening late in the second quarter. Although higher interest rates reduced asset valuations during the second quarter, the Company's hedging portfolio effectively mitigated much of this impact, supporting the overall increase in book value. The Company grew its capital base by $391 million, using the net proceeds to opportunistically add $2.8 billion of Agency MBS. As a result, the total investment portfolio grew 11% to $27.6 billion compared to $24.8 billion as of March 31, 2026. Leverage including TBAs at their implied cost decreased to 8.1 times equity primarily due to the favorable performance of the Company's portfolio. Interest income increased compared to the first quarter of 2026, driven by the Company’s continued deployment of capital into Agency MBS purchases. Operating expenses decreased by $5 million quarter over quarter, driven by the absence of one time compensation and personnel related costs recognized during the first quarter of 2026. The following tables summarize the changes in the Company's financial position during the second quarter of 2026: 2

(2) Average balance for liabilities is calculated as a simple average of the daily repurchase agreement borrowings outstanding during the period. (3) Effective yield is calculated by dividing annualized interest income by the average balance of asset type outstanding during the reporting period. Unscheduled adjustments to premium/discount amortization/accretion, such as for prepayment compensation, are not annualized in this calculation. (4) Financing cost is calculated by dividing annualized interest expense by the total average balance of borrowings outstanding during the period with an assumption of 360 days in a year. (5) CMBS IO ("Interest only") includes Agency and non-Agency issued securities. (6) Represents a non-GAAP measure.

Non-GAAP Financial Measures In addition to reporting the Company’s financial results determined in accordance with GAAP, management of the Company believes that investors’ understanding of our operating results may be enhanced by the use of non-GAAP financial measures, which are used by management internally, along with GAAP measures, to evaluate our performance. Our non-GAAP financial measures include earnings available for distribution (“EAD”) to common shareholders (including per common share) and economic net interest income and the related metric economic net interest spread. Management believes these non-GAAP financial measures may be useful to investors because they are viewed by management as additional measures of the investment portfolio’s return. Drop income generated by TBA dollar roll positions, which is included in "gain (loss) on derivatives instruments, net" on the Company's consolidated statements of comprehensive income, is included in EAD because management views drop income as the economic equivalent of net interest income (interest income less implied financing cost) on the underlying Agency security from trade date to settlement date. However, drop income does not represent the total realized gain/loss from the Company’s investments in TBA securities. Management also includes net periodic interest from its interest rate swaps, which is included in "gain (loss) on derivatives instruments, net," in EAD and economic net interest income because interest rate swaps are used by the Company to economically hedge the impact of changing interest rates on its borrowing costs from repurchase agreements, and including net periodic interest from interest rate swaps is a helpful indicator of the Company’s total financing cost in addition to GAAP interest expense. Non-GAAP financial measures are not a substitute for GAAP measures and may be different from non-GAAP measures used by other companies. In addition, other companies, including in our industry, may calculate comparable measures differently, which reduces their usefulness as comparative measures. Investors should not rely on any single financial measure when evaluating our business. These non-GAAP measures should be considered as supplemental in nature and not as a substitute for our operating results in accordance with GAAP. Reconciliations of each non-GAAP measure to certain GAAP financial measures are provided below. 9
