On December 18, 2017, Invesco Mortgage Capital Inc., a Maryland corporation (the “Company”), IAS Operating Partnership LP and Invesco Advisers, Inc. entered into an equity distribution agreement (the “Equity Distribution Agreement”) with JMP Securities LLC (the “Placement Agent”) pursuant to which the Company may sell up to 17,000,000 shares of the Company’s common stock, par value $0.01 per share (the “Shares”), from time to time through the Placement Agent. The Shares will be registered with the Securities and Exchange Commission (the “Commission”) pursuant to the Company’s Registration Statement on Form S-3ASR (File No. 333-210454) (as the same may be amended and/or supplemented, the “Registration Statement”), under the Securities Act of 1933, as amended (the “Securities Act”). The Company has filed with the Commission a prospectus supplement, dated December 18, 2017, to the prospectus dated March 29, 2016 included in the Registration Statement, in connection with the offer and sale of the Shares from time to time in the future.

Pursuant to the Equity Distribution Agreement, the Shares may be offered and sold through the Placement Agent in transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act, including sales made directly on the New York Stock Exchange, sales made to or through a market maker other than on an exchange, or subject to the terms of a written notice from the Company, in privately negotiated transactions (which may include block trades). Under the Equity Distribution Agreement, the Placement Agent will be entitled to compensation of up to 2.00% of the gross proceeds from the sale of the Shares sold through the Placement Agent from time to time pursuant to the terms of the Equity Distribution Agreement. The Company has no obligation to sell any of the Shares under the Equity Distribution Agreement and may at any time suspend solicitations and offers under the Equity Distribution Agreement.
