14 HEDGING APPROACH MODERATES THE VOLATILITY OF PFSI’S RESULTS MSR Valuation Changes and Offsets ($ in millions) MSR fair value change before realization of cash flows Hedging and related gains (losses) Production pretax income • PFSI seeks to moderate the impact of interest rate changes on the fair value of its MSR asset through a comprehensive hedging strategy that also considers production-related income • In 3Q24, MSR fair value decreased due to lower market interest rates • Hedging gains, excluding hedge costs, offset 78% of MSR fair value declines – Hedge costs were significantly elevated during the quarter given interest rate volatility and the inverted yield curve • Production pretax income was $108 million, up from $41 million in the prior quarter

INVESTMENT MANAGEMENT SEGMENT HIGHLIGHTS 15 Investment Management AUM ($ in billions) Investment Management Revenues ($ in millions) ● Net AUM as of September 30, 2024 were $1.9 billion, essentially unchanged from June 30, 2024 and September 30, 2023 ● Investment Management segment revenues were $9.4 million, essentially unchanged from 2Q24 and up 7% from 3Q23
