Item 8.01  Other Events.

On August 7, 2012, PennyMac Mortgage Investment Trust (the “Company”), PennyMac Operating Partnership, L.P. and PNMAC Capital Management, LLC entered into an ATM Equity OfferingSM Sales Agreement (the “Sales Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated (the “Agent”) to sell the Company’s common shares of beneficial interest, par value $0.01 per share, having an aggregate offering price of up to $200,000,000 (the “Shares”), from time to time through an “at the market” equity offering program under which the Agent will act as sales agent and/or principal.

Subject to the terms and conditions of the Sales Agreement, the Agent will use its commercially reasonable efforts consistent with its normal trading and sales practice to sell the Shares as directed by the Company.  The sales, if any, of the Shares made under the Sales Agreement may be made by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act of 1933, including sales made directly on the New York Stock Exchange, or sales made to or through a market maker other than on an exchange or, with the written consent of the Company, in privately negotiated transactions.

The Sales Agreement provides that the Agent will be entitled to a commission for its service that will not exceed, but may be lower than, 2.0% of the gross sales price of the Shares sold through it as sales agent pursuant to the Sales Agreement.  Under the terms of the Sales Agreement, the Company may also sell Shares to the Agent as principal at prices agreed upon at the time of sale.  The Company has no obligation to sell any of the Shares under the Sales Agreement, and may at any time suspend solicitation and offers under the Sales Agreement.

The Shares, if any, will be issued pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-182261).  The Company filed a Prospectus Supplement, dated August 7, 2012, to the Prospectus, dated June 21, 2012, with the Securities and Exchange Commission in connection with the offer and sale of the Shares.

A copy of the Sales Agreement is attached as Exhibit 1.1 to this Current Report on Form 8-K, and is incorporated by reference herein.
