[8-K] PennyMac Mortgage Investment Trust Reports Material Event

Rhea-AI Filing Summary

PennyMac Mortgage Investment Trust disclosed that its indirect wholly owned subsidiary, PennyMac Corp., issued $75 million aggregate principal amount of 8.500% Exchangeable Senior Notes due 2029 in a registered direct placement. This reopening brings the total outstanding notes in this series to $291,500,000 in aggregate principal amount.

Net proceeds were approximately $75.5 million, which are intended to repay borrowings under secured mortgage servicing rights and servicing advance facilities, repurchase or repay a portion of the Issuer’s 5.50% Exchangeable Senior Notes due 2026, and fund other general business purposes. The notes mature on June 1, 2029 and pay interest at 8.500% per year, semiannually on June 1 and December 1.

Holders can exchange each $1,000 principal amount into 63.3332 common shares, equivalent to an initial exchange price of approximately $15.79 per share, with PennyMac Corp. paying principal in cash and settling any excess value in cash, common shares, or both. The notes and the parent guarantee are senior unsecured obligations and include holder put rights upon certain corporate events.

PennyMac Corp. adds $75 million of 8.500% 2029 exchangeable notes, mainly to refinance existing obligations.

PennyMac Corp., an indirect subsidiary of PennyMac Mortgage Investment Trust, issued $75 million of 8.500% Exchangeable Senior Notes due 2029, increasing this note series to $291,500,000 outstanding. These notes pay a fixed 8.500% coupon, higher than the Issuer’s 5.50% Exchangeable Senior Notes due 2026 that are among the targeted uses of proceeds.

Net proceeds of approximately $75.5 million are intended to repay secured mortgage servicing rights and servicing advance facilities, reduce part of the 5.50% notes due 2026, and support other general business purposes. This shifts a portion of nearer-term and secured funding into longer-dated senior unsecured exchangeable debt, changing the mix but not eliminating leverage.

The initial exchange rate of 63.3332 common shares per $1,000 principal, equivalent to an initial exchange price of about $15.79 per share, introduces potential future equity issuance if holders choose to exchange. The notes and the parent guarantee rank as senior unsecured obligations, while remaining effectively junior to secured debt and structurally junior to subsidiary liabilities, so overall impact depends on the broader balance sheet disclosed in other reports.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

On December 15, 2025, PennyMac Corp. (the “Issuer”), an indirect, wholly-owned subsidiary of PennyMac Mortgage Investment Trust (the “Company”), issued $75 million aggregate principal amount of the Issuer’s 8.500% Exchangeable Senior Notes due 2029 (the “2029 Exchangeable Notes”) in a direct placement registered under the Securities Act of 1933, as amended, pursuant to securities purchase agreements with the respective investors named therein (the “Offering”). As used herein, the term “2029 Exchangeable Notes” includes the Existing Notes (as defined below), unless the context requires otherwise.

The 2029 Exchangeable Notes issued in the Offering were issued as a reopening of, and are part of the same series with, the 8.500% Exchangeable Senior Notes due 2029 that the Company previously issued in May 2024 (the “Existing Notes”). Upon completion of the Offering, the aggregate principal amount of outstanding Notes was $291,500,000.

The 2029 Exchangeable Notes were issued pursuant to an Indenture, dated as of April 30, 2013 (the “Base Indenture”), among the Issuer, the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), as supplemented by the Fourth Supplemental Indenture, dated as of May 24, 2024 (the “Supplemental Indenture” and, collectively with the Base Indenture, the “Indenture”), among the Issuer, the Company and the Trustee.

The net proceeds from the Offering were approximately $75.5 million, after deducting estimated offering expenses. The net proceeds from the Offering 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 the Issuer’s 5.50% Exchangeable Senior Notes due 2026; and for other general business purposes.

The 2029 Exchangeable Notes will mature on June 1, 2029 unless repurchased or exchanged in accordance with their terms prior to such date. The 2029 Exchangeable Notes bear interest at a rate of 8.500% per year, payable semiannually in arrears on June 1 and December 1 of each year, beginning (in the case of the 2029 Exchangeable Notes issued in the Offering) on June 1, 2026. The 2029 Exchangeable Notes are fully and unconditionally guaranteed by the Company. Upon exchange, the Issuer will pay cash up to the aggregate principal amount of the 2029 Exchangeable Notes to be exchanged and pay or deliver, as the case may be, cash, the Company’s common shares of beneficial interest (“Common Shares”), or a combination thereof, at the Issuer’s election, in respect of the remainder, if any, of its exchange obligation in excess of the aggregate principal amount of the 2029 Exchangeable Notes to be exchanged. The exchange rate initially equals 63.3332 Common Shares per $1,000 principal amount of 2029 Exchangeable Notes (equivalent to an initial exchange price of approximately $15.79 per Common Share). The exchange rate will be subject to adjustment upon the occurrence of certain events, but will not be adjusted for any accrued and unpaid interest. In addition, following the occurrence of certain corporate events, the Issuer will, in certain circumstances, increase the exchange rate for a holder that exchanges its 2029 Exchangeable Notes in connection with such corporate events.

The Issuer may not redeem the 2029 Exchangeable Notes prior to maturity, and no sinking fund will be provided for the 2029 Exchangeable Notes. If certain corporate events occur, subject to certain conditions, holders of the 2029 Exchangeable Notes may require the

Issuer to purchase for cash all or part of their 2029 Exchangeable Notes at a repurchase price of 100% of the principal amount of the 2029 Exchangeable Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date.

The 2029 Exchangeable Notes are the Issuer’s senior unsecured obligations and rank senior in right of payment to any of the Issuer’s indebtedness that is expressly subordinated in right of payment to the 2029 Exchangeable Notes, equal to any of the Issuer’s unsecured indebtedness that is not so subordinated, effectively junior to any of the Issuer’s secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally junior to all indebtedness and other liabilities (including trade payables) and preferred equity of the Issuer’s subsidiaries. The guarantee is the Company’s senior unsecured obligation and ranks senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the guarantee, equal to any of the Company’s other unsecured indebtedness that is not so subordinated, effectively junior to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally junior to all indebtedness and other liabilities (including trade payables) and preferred equity of the Company’s subsidiaries.

The 2029 Exchangeable Notes were issued pursuant to an effective shelf registration statement filed with the Securities and Exchange Commission on Form S-3ASR (File Nos. 333-280211 and 333-280211-01), which was filed on June 14, 2024, including Post-Effective Amendment No. 1 thereto, which was filed on December 11, 2025 (collectively, the “Registration Statement”), a base prospectus, dated June 14, 2024, including supplement no. 1 thereto, dated December 11, 2025, and a related prospectus supplement, dated December 11, 2025, filed with the Securities and Exchange Commission pursuant to Rule 424(b) under the Securities Act of 1933, as amended.

The foregoing description of the Indenture and the 2029 Exchangeable Notes does not purport to be complete and is qualified in its entirety by reference to the full text of the Indenture (including the form of the 2029 Exchangeable Notes), filed as an exhibit to the Registration Statement.
