| AmendmentDescription | This Current Report on Form 8-K/A (the “Amendment”) is being filed as an amendment to the Current Report on Form 8-K filed by Orchid Island Capital, Inc. (the “Company”) on July 14, 2022 (the “Original 8-K”) reporting, among other things, the dividend declared by the Company’s board of directors for the month of July 2022 (the “July Dividend”). The Original 8-K incorrectly stated the amount of the July Dividend as $0.035 per share of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The July Dividend is in fact $0.045 per share of Common Stock. Except as amended by this Amendment, all information set forth in the Original 8-K and corresponding exhibits remains unchanged. |
