Management Remarks

“We believe today’s Agency mortgage market presents a compelling forward investment opportunity,” said Smriti Laxman Popenoe, Co-Chief Executive Officer and President. “Late-quarter volatility and wider mortgage spreads reduced our reported book value, and that repricing has created an attractive forward return opportunity. Importantly, the mortgage market remains fundamentally solid, technical conditions are strong, and financing remains stable. We are managing for the long term, prepared for a range of market scenarios, and positioned to capitalize on opportunities as they develop.”

Summary of Third Quarter 2026 Results

Total economic return for the third quarter of 2026 reflected a decline in book value per common share to $10.91, inclusive of dividends declared of $0.51 per common share. Book value declined primarily due to wider Agency MBS spreads, which drove a net decrease in the fair value of the Company's investment portfolio. Gains on the Company's interest rate hedging portfolio partially offset these losses. While the Company's active management of its hedges mitigated a portion of the impact from changing interest rates and broader market volatility, spread widening remained the primary driver of pressure on asset valuations and book value during the quarter.

The Company grew its capital base by $384 million during the third quarter through a combination of common and preferred equity raises, using the net proceeds to opportunistically add $3.2 billion of Agency MBS. As a result, the total investment portfolio grew approximately 3% to $28.3 billion compared to $27.6 billion as of June 30, 2026. Leverage, including the implied cost of TBAs, increased to 9.0 times shareholders' equity, primarily due to lower book value related to the investment portfolio's performance.

Interest income increased from the prior quarter, driven by the Company's continued capital deployment into Agency MBS. The average balance of interest-earning assets grew 10% during the third quarter of 2026. Operating expenses decreased by $4 million quarter over quarter due to lower stock-based compensation.

The following tables summarize the changes in the Company's financial position during the third quarter of 2026:

The Company typically designates certain of its interest rate derivatives as hedges for tax purposes. Gains and losses realized upon maturity or termination of derivatives designated as hedges for tax purposes are amortized into the Company's REIT taxable income over the original periods hedged by those derivatives. These hedge gains are not included in the Company's current or future earnings available for distribution ("EAD"), a non-GAAP measure, but will be part of the Company's future distribution requirements. The table below provides the projected amortization of the Company's net deferred tax hedge gains that may be recognized as taxable income over the periods indicated, given conditions known as of September 30, 2026; however, uncertainty inherent in the forward interest rate curve makes future realized gains and losses difficult to estimate, and as such, these projections are subject to change for any given period.

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.
