PennyMac Mortgage Investment Trust Prices Further Reopening of $75 Million of 8.500% Exchangeable Senior Notes Due 2029

WESTLAKE VILLAGE, Calif.–(BUSINESS WIRE)–PennyMac Mortgage Investment Trust (NYSE: PMT) (“PMT” or the “Company”) today announced that its indirect wholly-owned subsidiary, PennyMac Corp. (“PMC”), has priced an offering of $75 million aggregate principal amount of its 8.500% Exchangeable Senior Notes due 2029 (the “Notes”) to an investor in a direct placement registered under the Securities Act of 1933, as amended. The Notes will be issued as a further reopening of, and will be part of the same series as, the $291.5 million aggregate principal amount of 8.500% Exchangeable Senior Notes due 2029 that PMC previously issued in May 2024 and in a reopening earlier in December 2025, all of which are outstanding. The issuance and sale of the Notes are expected to close on December 22, 2025, subject to the satisfaction of certain closing conditions. Interest on the Notes is payable semiannually in arrears on June 1 and December 1 of each year. The Notes will be fully and unconditionally guaranteed by the Company.

Upon exchange, PMC will pay cash up to the aggregate principal amount of the Notes to be exchanged and pay or deliver, as the case may be, cash, PMT’s common shares of beneficial interest (“Common Shares”) or a combination thereof, at PMC’s election, in respect of the remainder, if any, of its exchange obligation in excess of the aggregate principal amount of the Notes being exchanged. The exchange rate will initially equal 63.3332 Common Shares per $1,000 principal amount of Notes, which is equivalent to an initial exchange price of approximately $15.79 per Common Share. The initial exchange price is approximately 20% above the $13.19 per share closing price of PMT’s Common Shares on the New York Stock Exchange on December 18, 2025, and is subject to adjustment in accordance with the terms of the Notes. The Notes will be PMC’s senior unsecured obligations and will rank equally with all of its present and future senior unsecured debt and senior to any future subordinated debt. The Notes will mature on June 1, 2029 unless repurchased or exchanged in accordance with their terms prior to such date.

Net proceeds from the offering are expected to be approximately $75.6 million, after deducting estimated offering expenses payable by PMC. The net proceeds are intended to be used for the repayment of a portion of the borrowings outstanding under the Company’s secured mortgage servicing rights and servicing advance facilities; the repurchase or repayment of a portion of PMC’s 5.500% Exchangeable Senior Notes due 2026; and for other general corporate purposes.

The offering is being made pursuant to an effective shelf registration statement and prospectus, including a supplement thereto, and a related prospectus supplement, a copy of which, when available, may be obtained free of charge on the SEC’s website at www.sec.gov or by contacting the Company, attention: Investor Relations, at 3043 Townsgate Road, Westlake Village, California 91361, telephone: 818.224.7028.
