ESTIMATED THIRD QUARTER 2025 RESULTS,

OCTOBER 2025 MONTHLY DIVIDEND AND

 SEPTEMBER 30, 2025 RMBS PORTFOLIO CHARACTERISTICS

Vero Beach, Fla., October 15, 2025 - Orchid Island Capital, Inc. (the “Company”) (NYSE: ORC) announced today that the Board of Directors of the Company declared a monthly cash dividend for the month of October 2025. The dividend of $0.12 per share will be paid November 26, 2025 to holders of record of the Company’s common stock on October 31, 2025, with an ex-dividend date of October 31, 2025. The Company plans on announcing its next common stock dividend on November 12, 2025.

The Company intends to make regular monthly cash distributions to its holders of common stock. In order to qualify as a real estate investment trust (“REIT”), the Company must distribute annually to its stockholders an amount at least equal to 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gain. The Company will be subject to income tax on taxable income that is not distributed and to an excise tax to the extent that a certain percentage of its taxable income is not distributed by specified dates. The Company has not established a minimum distribution payment level and is not assured of its ability to make distributions to stockholders in the future.

As of October 15, 2025, the Company has 151,712,160 shares of common stock outstanding. As of September 30, 2025, the Company had 148,239,401 shares of common stock outstanding. As of June 30, 2025, the Company had 126,566,926 shares of common stock outstanding.

Estimated September 30, 2025 Book Value Per Share

The Company’s estimated book value per share as of September 30, 2025 was $7.33.  The Company computes book value per share by dividing total stockholders' equity by the total number of outstanding shares of common stock. At September 30, 2025, the Company's preliminary estimated total stockholders' equity was approximately $1,086.1 million with 148,239,401 shares of common stock outstanding. These figures and the resulting estimated book value per share are preliminary, subject to change, and subject to review by the Company’s independent registered public accounting firm. 

Estimated Net Income Per Share and Realized and Unrealized Gains on RMBS and Derivative Instruments

The Company estimates it generated a net income per share of $0.53 for the quarter ended September 30, 2025, which includes an estimated $0.37 per share of net realized and unrealized gains on RMBS and derivative instruments. These amounts compare to total dividends declared during the quarter of $0.36 per share. Net income per common share calculated under generally accepted accounting principles can, and does, differ from our REIT taxable income.  The Company views REIT taxable income as a better indication of income to be paid in the form of a dividend rather than net income. Many components of REIT taxable income can only be estimated at this time and our monthly dividends declared are based on both estimates of REIT taxable income to be earned over the course of the current quarter and calendar year and a longer-term estimate of the REIT taxable income of the Company. These figures are preliminary, subject to change, and subject to review by the Company’s independent registered public accounting firm. 

Estimated Total Return on Equity

The Company’s estimated total return on equity for the quarter ended September 30, 2025 was 6.6%. The Company calculates total return on equity as the sum of dividends declared and paid during the quarter plus changes in book value during the quarter, divided by the Company’s stockholders’ equity at the beginning of the quarter.  The total return was $0.48 per share, comprised of dividends per share of $0.36 and an increase in book value per share of $0.12 from June 30, 2025.

Details of the RMBS portfolio as of September 30, 2025 are presented below. These figures are preliminary and subject to change and, with respect to figures that will appear in the Company’s financial statements and associated footnotes as of and for the quarter ended September 30, 2025, are subject to review by the Company’s independent registered public accounting firm:
