On December 16, 2024, PennyMac Mortgage Investment Trust and its subsidiaries entered into five amended and restated agreements with affiliates, including a management agreement with PNMAC Capital Management and servicing agreements with PennyMac Loan Services.

Management and 5th A&R servicing agreements now expire December 31, 2029, with automatic 18-month renewals unless terminated.

Briefs are written by AI from the filing text and can contain mistakes — open the filing before acting on anything. Impact (1-5) and tone are the AI's reading of the filing for shareholders, not a price forecast. Not investment advice.
Briefs marked “Written later” were written in November 2026 for filings that were by then more than three weeks old, so months before mid-October 2026 hold a selection: every material 8-K of the past year for the 100 largest companies we cover and the last 15 important 8-Ks of every other one. Briefs the number check holds back are not shown or counted. Also: the last 45 days, briefs by company, A–Z and the live SEC filings wire.
