PennyMac Mortgage Investment Trust Reports Results for First Post-IPO Period Ended September 30, 2009

In its initial period of operations ended September 30, 2009, the Company invested approximately $69.5 million of the proceeds from its equity offerings in residential mortgage-backed securities having an aggregate unpaid principal balance of approximately $72.9 million. The Company acquired these securities pending its anticipated reinvestment of the proceeds in suitable pools of mortgage loans or longer-lived, higher yielding mortgage-backed securities. The acquired securities are backed by non-agency Alt-A, subprime and prime jumbo loans and are currently cash-flowing senior priority securities with a weighted average remaining life of approximately one-and-one-half years and a weighted average yield of 7.13%.

The following is a summary of the Company’s portfolio of mortgage-backed securities as of September 30, 2009:

The Company’s initial investments produced total revenues of $816,000, offset by management fees and other expenses, resulting in a net loss of $730,000, or $0.04 per share, for the period ended September 30, 2009.

Stanford L. Kurland, Chairman and Chief Executive Officer of PennyMac, commented on the period’s results, “In PMT’s first two months of operations, our manager reviewed residential whole loan and securities portfolios with cumulative unpaid principal balances of over $6.9 billion and bid on several of those portfolios at levels consistent with our yield requirements. While some market participants have been willing to accept lower yields and bid more aggressively, we still believe that it is in the best interest of our shareholders over the long term to remain patient in order to maximize the returns from our long-term investment opportunities. Currently, our manager is reviewing over $1.9 billion in unpaid principal balances of residential whole loan and securities portfolios, and we expect that the volume of troubled residential mortgage loans available for sale will continue to grow. Additionally, our manager continues to build a conduit operation that could potentially allow us to capitalize on current market opportunities to provide small mortgage lenders an outlet for their newly originated mortgage loans.”

Management’s presentation will be available in the Investor Relations section of the Company’s website at www.pennymacmortgageinvestmenttrust.com beginning November 6, 2009.
