Vero Beach, Fla., July 13, 2026 - Orchid Island Capital, Inc. (the “Company”) (NYSE: ORC) announced today its estimated second quarter of 2026 results and portfolio characteristics as of June 30, 2026.

Shares Outstanding

As of July 13, 2026 and June 30, 2026, the Company had 199,603,438 shares of common stock outstanding. As of March 31, 2026, the Company had 196,700,226 shares of common stock outstanding.

Estimated June 30, 2026 Book Value Per Share

The Company’s estimated book value per share as of June 30, 2026 was $7.22.  The Company computes book value per share by dividing total stockholders' equity by the total number of outstanding shares of common stock. At June 30, 2026, the Company's preliminary estimated total stockholders' equity was approximately $1.4 billion with 199,603,438 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 net income per share of $0.44 for the quarter ended June 30, 2026, which includes an estimated $0.18 per share of net realized and unrealized gains on RMBS and derivative instruments. These amounts compare to total dividends declared during the quarter of $0.30 per share. Net income per common share calculated under generally accepted accounting principles can, and does, differ from our real estate investment trust ("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 June 30, 2026 was 6.2%. 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 $0.44 per share, comprised of dividends per share of $0.30 and an increase in book value per share of $0.14 from June 30, 2026.

Details of the RMBS portfolio as of June 30, 2026 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 June 30, 2026, are subject to review by the Company’s independent registered public accounting firm:
