3 Recent Developments Quarter to Date ▪ Financial markets have demonstrated significant volatility related to the spread of the novel coronavirus and potential economic slowdown in the near term (spending and work interruptions) and over the longer term (increased risk of recession) ▪ Interest rates have fallen to historic lows, providing a favorable environment for mortgage origination. PFSI is capturing elevated production volumes and margins across all three production channels, reflecting industry capacity constraints, PFSI’s operational response and PFSI’s industry leadership. ▪ PFSI hedges its exposure to changes in interest rates utilizing interest rate hedge instruments. The significant fair value gains on hedge instruments have offset the significant reduction in fair value of PFSI’s mortgage servicing rights (MSRs) due to increased expectations for prepayments. ▪ PFSI’s strong balance sheet, low leverage and disciplined approach to liquidity management are critically important in the current market environment (see slide 4) ▪ PFSI continues to expand its operational capacity to address the robust production environment and changing servicing needs (e.g., increased customer hardship, loss mitigation) and is taking appropriate steps to ensure the continuity of business operations (see slide 5)

Changes in the Market Environment and Impact on PFSI’s Liquidity 4 Item Liquidity Considerations ▪ Loss in value of production pipeline hedges (forward MBS sales) due to increases in MBS prices ▪ Fair value losses on MSRs due to increased expectations for prepayments ▪ Increased loan production volumes ▪ Warehouse financing is diversified across nine large global banks with facilities totaling $5.9 billion; sized for elevated production volumes (1) ▪ Margin calls offset by margin released upon settlement of new production pools (short - term timing difference) ▪ Potential for margin calls under MSR financing structure more than offset by gains on hedge instruments ▪ Further mitigated as PFSI has borrowed less than maximum available advance (i.e., has excess collateral) ▪ PFSI’s total liquidity has increased as a result of market events quarter - to - date ▪ Reflects PFSI’s disciplined approach to liquidity and capital management throughout its over 12 - year history (1 ) Includes two large banks that are participants in a syndicated facility
