MFA Financial, Inc. Announces
Pricing of Public Offering of Common Stock

MFA Financial, Inc. (NYSE: MFA) announced today the pricing of an underwritten public offering of 50,000,000 shares of its common stock, at a price to the public of $7.05 per share, for gross proceeds of $ 352.5 million. MFA has granted the underwriters a 30-day option to purchase up to an additional 7,500,000 shares of common stock to cover over-allotments, if any. All of the shares are being offered by MFA from its existing shelf registration statement filed with the Securities and Exchange Commission.

The estimated net proceeds to MFA from this offering, after the payment of underwriting discounts and commissions and related expenses, are expected to be approximately $ 336.2 million. MFA intends to use the net proceeds from this offering to acquire additional residential mortgage-backed securities (“MBS”), including senior most tranches of non-agency MBS, consistent with its investment policy and for working capital, which may include, among other things, the repayment of its repurchase agreements.

MFA expects to close the transaction on or about Tuesday, August 4, 2009, subject to the satisfaction of customary closing conditions.

Morgan Stanley and Deutsche Bank Securities are acting as joint book-running managers for the offering, with Credit Suisse, JMP Securities, UBS Investment Bank, Cantor Fitzgerald & Co. and Keefe, Bruyette & Woods acting as co-managers.
