Notable activity after quarter-end:

“PMT’s first quarter net loss was primarily driven by fair value declines in its credit sensitive strategies due to spread widening that resulted from economic uncertainty across financial markets and a provision for tax expense driven by fair value increases in its taxable REIT subsidiary,” said Chairman and CEO, David Spector. “In addition, competitive pressure in the conventional correspondent production channel continued as mortgage rates increased to levels not seen in more than a decade. Conversely, PMT’s interest rate sensitive strategies performed well, benefiting from MSR net valuation related gains that primarily resulted from lower expected prepayment activity in the future.”

Mr. Spector continued, “While the origination market continues to transition, higher interest rates and wider credit spreads are presenting attractive opportunities for PMT to deploy capital. We continued to invest in subordinate tranches from the securitization of our own production of investor loans during the quarter. Additionally, we recently opportunistically invested more than $140 million in securities with attractive expected returns from newly issued Agency CRT transactions and non-agency securitizations. As the mortgage environment continues to evolve, PMT remains well-positioned with the deep knowledge and expertise of this management team to find and invest in assets with attractive, long-term risk-adjusted returns.”

The following table presents the pretax income contributions of PMT’s segments:

Credit Sensitive Strategies Segment

The Credit Sensitive Strategies segment primarily includes results from PMT’s organically-created GSE CRT investments, investments in non-agency subordinate bonds from private-label securitizations of PMT’s production, opportunistic investments in GSE CRT and other legacy investments.  Pretax loss for the segment was $56.0 million on net investment losses of $52.7 million, compared to pretax income of $33.2 million on net investment income of $38.8 million in the prior quarter.

Net losses on investments in the segment were $44.9 million, compared to net gains on investments of $48.3 million in the prior quarter and included $35.6 million in net losses on PMT’s organically-created GSE CRT investments, $7.4 million in net losses from investments in non-agency subordinate bonds from PMT’s production, $2.3 million in net losses on mortgage-backed securities (MBS) and $0.4 million in net gains on loans at fair value.  

Net losses on PMT’s organically-created CRT investments for the quarter were $35.6 million, compared to net gains of $43.1 million in the prior quarter, and included $74.9 million in valuation-related losses, which reflected the impact of credit spread widening. The prior quarter included $1.6 million in valuation-related gains. Net losses

on PMT’s organically-created CRT investments also included $23.3 million in realized gains and carry, compared to $26.9 million in the prior quarter.  Recoveries net of realized losses during the quarter were $16.0 million, primarily related to L Street Securities 2017-PM1, as losses were reversed for loans that had been in forbearance and reperformed.

During the quarter, PMT retained mortgage securities from a PMT securitization of agency-eligible investor loans totaling $420 million in UPB. This resulted in approximately $23 million in fair value of new investments, net of associated asset-backed financing. PMT also opportunistically invested $86 million in floating-rate CRT bonds recently issued by Freddie Mac and Fannie Mae.

Net interest expense for the segment totaled $8.1 million, compared to $11.2 million in the prior quarter. Interest income totaled $2.1 million, up from $1.1 million in the prior quarter. Interest expense totaled $10.1 million, down from $12.3 million in the prior quarter due to decreased financing expenses as a result of smaller CRT balances.

Segment expenses were $3.3 million, down from $5.7 million in the prior quarter.

Interest Rate Sensitive Strategies Segment

The Interest Rate Sensitive Strategies segment includes results from investments in MSRs, Agency mortgage-backed securities (MBS), non-Agency senior MBS and interest rate hedges. Pretax income for the segment was $84.2 million on net investment income of $107.4 million, compared to a pretax loss of $43.2 million on net investment losses of $20.8 million in the prior quarter. The segment includes investments that typically have offsetting fair value exposures to changes in interest rates. For example, in a period with increasing interest rates, MSRs are expected to increase in fair value whereas Agency pass through and non-Agency senior MBS are expected to decrease in fair value.

The results in the Interest Rate Sensitive Strategies segment consist of net gains and losses on investments, net interest income and net loan servicing fees, as well as associated expenses.

Net loss on investments for the segment was $184.2 million and consisted of losses on MBS due to higher interest rates.

Net loan servicing fees were $304.2 million, compared to $12.2 million in the prior quarter. Net loan servicing fees included servicing fees of $146.9 million, down slightly from the prior quarter due to seasonal collection trends, and $9.1 million in other fees, reduced by $88.9 million in realization of MSR cash flows, which were up slightly from the prior quarter driven by higher average MSR values. Net loan servicing fees also included $392.6 million in fair value increases of MSRs, $163.8 million in related hedging declines, and $8.3 million of MSR recapture income. PMT’s hedging activities are intended to manage the Company’s net exposure across all interest rate sensitive strategies, which include MSRs and MBS.

The following schedule details net loan servicing fees:

⁽¹⁾ Includes contractually specified servicing fees, net of guarantee fees.

The fair value of the MSR increased by $392.6 million in the quarter, driven by higher mortgage rates which resulted in expectations for lower prepayment activity in the future. Agency MBS and interest rate hedges decreased in fair value as a result of increases in market interest rates.

Additionally, during the quarter PMT opportunistically invested $27 million in fixed-rate bonds from a senior tranche of a recently completed jumbo securitization.

Net interest expense for the segment was $12.6 million, versus net interest expense of $19.9 million in the prior quarter. Interest income totaled $29.1 million, up from $22.7 million in the prior quarter due to higher average MBS balances and a decline in prepayment activity. Interest expense totaled $41.7 million, down slightly from the prior quarter primarily due to a reduction in interest shortfall from slower prepayment activity.

Segment expenses were $23.2 million, up slightly from $22.4 million in the prior quarter.

Correspondent Production Segment

PMT acquires newly originated loans from correspondent sellers and typically sells or securitizes the loans, resulting in current-period income and additions to its investments in MSRs related to a portion of its production. PMT’s Correspondent Production segment generated pretax income of $4.6 million, essentially unchanged from the prior quarter.

Through its correspondent production activities, PMT acquired $22.5 billion in UPB of loans, down 31 percent from the prior quarter and 56 percent from the first quarter of 2021. Of total correspondent acquisitions, conventional conforming acquisitions totaled $9.8 billion, and government-insured or guaranteed acquisitions totaled $12.7 billion, down from $17.2 billion and $15.7 billion, respectively, in the prior quarter. Interest rate lock commitments on conventional loans totaled $10.2 billion, down from $14.7 billion in the prior quarter, due to reduced market volumes driving elevated levels of competition for conventional loans, including from the GSEs.

5

Segment revenues were $26.5 million, a 13 percent decrease from the prior quarter and included other income of $15.0 million, which primarily consists of volume-based origination fees, net interest income of $7.6 million, and net gains on loans acquired for sale of $4.0 million. Net gain on loans acquired for sale in the quarter increased from the prior quarter as a result of higher overall gain on sale margins. Interest income was $19.2 million, down from $30.8 million in the prior quarter, and interest expense was $11.6 million, down from $18.9 million in the prior quarter, both due to lower volumes.

Segment expenses were $22.0 million, down from $25.8 million in the prior quarter driven by the decrease in acquisition volumes and slightly offset by an increase in the weighted average fulfillment fee rate. The weighted average fulfillment fee rate in the first quarter was 17 basis points, up from 12 basis points in the prior quarter.

Corporate Segment

The Corporate segment includes interest income from cash and short-term investments, management fees, and corporate expenses.

Segment revenues were $0.6 million, down from $1.2 million in the prior quarter. Management fees were $8.1 million, down from $8.9 million in the prior quarter. Other segment expenses were $7.2 million, up from $6.3 million in the prior quarter.

Taxes

PMT recorded a provision for tax expense of $37.2 million primarily driven by fair value increases in MSRs held in PMT’s taxable subsidiary.

3 Note: All figures are for 1Q22 or as of 3/31/22 (1) Net loss attributable to common shareholders includes a provision for tax expense of $37 million. As described in Note 3 of PMT’s Annual Report on form 10-K for the year ended Dec. 31, 2021, a recent accounting change requires that beginning in 2022, the portion of PMT’s senior notes that are exchangeable for PMT common shares of beneficial interest originally allocated to additional paid-in capital was reclassified to the carrying value of the exchangeable senior notes. Giving effect to this change on a pro forma basis, PMT’s book value as of Dec. 31, 2021 would have been $18.60. (2) EPS = earnings per share. GSE = Government-sponsored enterprises. CRT = credit risk transfer. MSR = mortgage servicing rights. (3) Excludes $84 million of market-driven value losses in the credit sensitive strategies and market-driven value gains of $43 million in the interest rate sensitive strategies – see slide 11 for additional details 3 FIRST QUARTER HIGHLIGHTS Net loss attributable to common shareholders(1) $(30)mm 1Q22 Results Diluted EPS(2) $(0.32) Return on common equity (7)% Book value per share(1) $17.87 Dividend and Other Shares repurchased 2.0mm Dividend per common share $0.47 CREDIT SENSITIVE STRATEGIES INTEREST RATE SENSITIVE STRATEGIES CORRESPONDENT PRODUCTION Pretax income $(56)mm Pretax income $5mm New investments in investor loan securitizations $23mm Conventional correspondent production volume $9.8bn Fair value of organically-created GSE CRT(2) investments $1.4bn Correspondent seller relationships 765 Pretax income New MSR(2) investments $195mm Fair value of MSR investments $3.4bn $84mm Income excluding market-driven value changes(3) $29mm Income excluding market-driven value changes(3) $41mm Net loss driven primarily by fair value declines in PMT’s Credit Sensitive Strategies due to credit spread widening and tax provisions in its taxable REIT subsidiary, partially offset by strong results in its Interest Rate Sensitive Strategies

5 PENNYMAC’S ROBUST RISK MANAGEMENT DISCIPLINES ARE ALIGNED WITH RECENT FHFA PROPOSALS The FHFA re-proposed eligibility standards for non-bank, Agency seller/servicers Tightened liquidity, net worth and leverage requirements for originators and servicers Additional requirements for large non-banks Liquidity buffer Capital and liquidity plans Third-party ratings PMT is well-positioned to meet these requirements given its long-standing commitment to enterprise risk management Historically operated with low leverage Strong liquidity and capital planning disciplines Includes successful hedging of interest rate risk; mitigates liquidity and capital volatility Robust reserves maintained for stress environments $1.0 billion(1) in available liquidity at March 31, 2022 Risk management disciplines fully integrated throughout the organization If adopted as proposed, PMT would be able to meet these requirements without raising additional capital (1) Available liquidity is unrestricted cash on hand and amounts that can be immediately borrowed on facilities with pledged collateral

RECENT OPPORTUNISTIC INVESTMENTS GIVEN HIGHER EXPECTED MARKET RETURNS 6 Rising interest rates and wider credit spreads have driven opportunities for PMT to deploy capital at attractive, long-term risk-adjusted returns PMT is targeting expected returns in the low-to-mid teens for these investment strategies Capital Deployed in 1Q22 Invested $86 million in floating-rate CRT bonds recently issued by Freddie Mac and Fannie Mae Invested $27 million in fixed-rate bonds from a senior tranche of a recently completed jumbo securitization Capital Deployed after quarter-end Invested $31 million in floating-rate CRT bonds recently issued by Freddie Mac and Fannie Mae PMT’s Equity Allocation 100% = $2.2 billion Credit Sensitive Strategies Interest Rate Sensitive Strategies Correspondent production Corporate (1) (1) Opportunistic investments in GSE CRT and other legacy investments

7 RUN-RATE RETURN POTENTIAL FROM PMT’S INVESTMENT STRATEGIES Note: This slide presents estimates for illustrative purposes only, using PMT’s base case assumptions (e.g., for credit performance, prepayment speeds, financing economics, and loss treatment for CRT transactions as described on slide 26), and does not contemplate fair value changes other than realization of cash flows and hedge costs, or significant changes or shocks to current market conditions. Actual results may differ materially.  (1) Equity allocated represents management’s internal allocation. Certain financing balances and associated interest expenses are allocated between investments based on management’s assessment of target leverage ratios and required capital or liquidity to support the investment. (2) Includes legacy distressed loan portfolio and opportunistic investments in GSE CRT (3) ROE calculated as a percentage of segment equity (4) ROE calculated as a percentage of total equity Represents the average annualized return and quarterly earnings potential PMT expects from its strategies over the next four quarters Reflects performance expectations in the highly-competitive, transitioning mortgage market Return potential of PMT’s organically-created investments in GSE CRT increased slightly from the prior quarter as credit spreads widened Continued periodic investments in investor loan securitizations More consistent returns for the interest rate sensitive strategies given slower prepayment speeds Higher interest rates have driven a smaller origination market resulting in lower volumes and significant competition in correspondent production for conventional loans has resulted in tight margins Excludes potential contributions from additional opportunistic investments or those under exploration, such as new investments in PMT’s organically-created GSE CRT or the introduction of new products other than investor loans PMT’s forecast for taxable income and liquidity continues to support the common dividend at its current level of $0.47 per share through 2022

8 CORRESPONDENT PRODUCTION HIGHLIGHTS Note: May not sum due to rounding (1) For government loans, PMT earns a sourcing fee and interest income for its holding period and does not pay a fulfillment fee to PFSI (2) Conventional conforming interest rate lock commitments (3) Based on funded loans subject to fulfillment fees (1) Correspondent acquisitions in 1Q22 totaled $22.5 billion in UPB, down 31% Q/Q and 56% Y/Y 43% conventional loans; 57% government loans Conventional conforming acquisitions of $9.8 billion in UPB, down 43% Q/Q and 71% Y/Y Government acquisitions of $12.7 billion in UPB, down 19% Q/Q and 27% Y/Y(1) Conventional lock volume was $10.2 billion in UPB, down 31% Q/Q and 70% Y/Y(2) Maintained pricing discipline despite significant competition for conventional loans in a contracting origination market, including from the GSEs Pennymac remains the largest correspondent aggregator in the U.S. April correspondent acquisitions totaled $6.5 billion in UPB; locks were $7.5 billion in UPB Correspondent Production Volume and Mix (UPB in billions)

9 TRENDS IN MSR INVESTMENTS MSR assets were $3.4 billion as of March 31st, up from $2.9 billion at December 31st, 2021 Driven by fair value increases and newly originated MSR investments of $195 million resulting from PMT’s conventional production volumes UPB associated with MSR investments increased to $219.0 billion from $216.1 billion at December 31st, 2021 MSR Investments ($ in millions)

10 TRENDS IN PMT’S UNIQUE INVESTMENTS IN GSE CREDIT RISK TRANSFER UPB and fair value of PMT’s organically-created CRT investments declined from December 31st, 2021 due to fair value decreases and prepayments 60+ day delinquency rate declined from December 31st, 2021 as the overall number of delinquent loans decreased faster than the decline in UPB Cumulative lifetime losses decreased due to recoveries of previously-recognized losses related to L Street Securities 2017-PM1 – see slide 23 Actively engaged in discussions with Fannie Mae and Freddie Mac regarding resumption of lender-risk share transactions(2) (1) The fair value of PMT’s organically created GSE CRT investments is reflected on PMT’s balance sheet as deposits securing CRT arrangements, and derivative and credit risk transfer strip assets or liabilities, net of the interest-only security payable. (2) Since the end of 2020, we have not created any new front-end lender risk share transactions and any future lender risk share transactions with Fannie Mae or Freddie Mac are subject to approval by the FHFA.

11 FIRST QUARTER RESULTS AND RETURN CONTRIBUTIONS BY STRATEGY Note: Amounts may not sum exactly due to rounding (1) Income contribution and the annualized return on equity calculated net of any direct expenses associated with investments (e.g., loan fulfillment fees and loan servicing fees), but before tax expenses. Some of the income associated with the investment strategies may be subject to taxation. (2) Categorization of income as market-driven value changes based on management assessment. Income excluding market-driven value changes does not represent REIT taxable income. (3) Equity allocated represents management’s internal allocation.

18 PMT’S INVESTMENT ACTIVITY BY STRATEGY DURING THE QUARTER Credit Sensitive Strategies Interest Rate Sensitive Strategies ($ in millions) (1) The fair value of PMT’s organically-created GSE CRT investments from is reflected on PMT’s balance sheet as deposits securing CRT arrangements, and derivative and credit risk transfer strip assets or liabilities, net of the interest-only security payable. (2) As discussed in Note 6 – Variable Interest Entities to our Annual Report on Form 10-K for the year ended December 31, 2021, we consolidate the assets and liabilities in the trust that issued the subordinate bonds. Accordingly, this investment is shown as Loans at fair value and Asset-backed financing of variable interest entities on our consolidated balance sheet. Net new investments includes the retention of subordinate bonds from a securitization of investor loans totaling $420 million. (3) Includes legacy distressed loan portfolio and opportunistic investments in GSE CRT. Net new investments also reflect sales in performing and non-performing loans as a part of PMT’s strategy to exit the investments. Includes $11.7 million in carrying value of real estate acquired in settlement of loans at 3/31/22. (4) MBS = Mortgage-backed securities. Net new investments in Agency MBS represents rebalancing of the MBS portfolio (considered along with to be announced (TBA) hedges in managing PMT’s interest rate risk) and runoff. (5) Net new investments represents new investments net of sales, liquidations, and runoff.

21 SERVICING TRENDS – DELINQUENCIES AND ADVANCES FOR PMT’S MSR PORTFOLIO Overall mortgage delinquency rates have returned to pre-pandemic levels; however, delinquency rates of seriously delinquent loans (90+ days) remains elevated In PMT’s conventional MSR portfolio, approximately 61,000 borrowers have been enrolled in a forbearance plan related to COVID-19 Through March 31st, approximately 58,000 borrowers have exited or are in the process of exiting their forbearance plan including those borrowers that have paid-in-full Servicing advances were approximately $93 million at March 31, 2022, down from $135 million at December 31 No P&I advances are outstanding as prepayment activity remains sufficient to cover the GSEs’ remittance obligations 30+ Day Delinquency Rate and Forbearance Trend(1) Note: Figures may not sum due to rounding (1) Delinquency and forbearance data based on loan count (i.e. not UPB). As of 3/31/22, 30+ day delinquency units amounted to 9,299, forbearance units amounted to 2,750, total portfolio units were 816,820, and portfolio UPB was $219.0 billion.
