First Quarter 2026 Highlights

o   Pretax income excluding valuation-related items was $56.7 million, up 25% from the prior quarter

“In the first quarter, PennyMac Financial generated an 8% annualized return on equity and an 11% annualized adjusted return on equity²,” said Chairman and CEO David Spector. “Our performance reflects our ongoing emphasis on maximizing returns on invested capital. The combination of strong operational execution in our consumer and broker direct lending channels along with improving operating efficiency drove production segment pretax income to its highest level in nearly five years. The growth in our direct channels was paired with our consistent strategic deployment of capital through the correspondent channel.”

Mr. Spector continued, “We are focused on driving growth where the marginal returns are most accretive to our current operating returns and where we can further lean into the operational scale we have achieved. We expect the acquisition of Cenlar to leverage the significant scale advantage of our tech-first platform and enhance our profitability over time. Despite expectations for a smaller origination market as interest rates move higher again, we remain confident in our ability to generate meaningful adjusted returns on equity as we move through 2026.”

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

Production Segment

The Production segment includes the correspondent acquisition of newly originated government-insured and conventional conforming loans for PFSI’s own account, fulfillment services on behalf of PMT and direct lending through the consumer direct and broker direct channels, including the underwriting and acquisition of loans from correspondent sellers on a non-delegated basis.

PFSI’s loan production activity for the quarter totaled $37.0 billion in UPB, $34.2 billion of which was for its own account, and $2.8 billion of which was fee-based fulfillment activity for PMT. Correspondent locks for PFSI and direct lending IRLCs totaled $41.1 billion in UPB, down 4% from the prior quarter and up 31% from the first quarter of 2025.

Production segment pretax income was $133.6 million, up from $127.3 million in the prior quarter and $61.9 million in the first quarter of 2025. Production segment net revenues totaled $406.9 million, up 10% from the prior quarter and 64% from the first quarter of 2025. The increase in revenue from the prior quarter and the first quarter of 2025 was primarily due to higher volumes in the direct lending channels.

The components of net gains on loans held for sale are detailed in the following table:

PFSI performs fulfillment services for certain conventional conforming and nonconforming loans that it acquires from non-affiliates in its correspondent production business and subsequently sells to PMT. These services include, but are not limited to, marketing, relationship management, correspondent seller approval and monitoring, loan file review, underwriting, pricing, hedging and activities related to the subsequent sale and securitization of loans in the secondary mortgage markets for PMT.

Fees earned from the fulfillment of correspondent loans on behalf of PMT totaled $5.7 million in the first quarter, down 12% from the prior quarter and up 8% from the first quarter of 2025. The decrease from the prior quarter was driven by lower acquisition volumes for PMT’s account.

Correspondent production volumes are initially acquired by PFSI. PMT retains the right to purchase up to 100% of non-government correspondent loan production. In the first quarter, PMT acquired all nonconforming correspondent production and 18% of total conventional conforming correspondent production.

Net interest income in the first quarter totaled $17.4 million, down from $19.8 million in the prior quarter. Interest income totaled $113.0 million, down from $129.0 million in the prior quarter, and interest expense totaled $95.6 million, down from $109.2 million in the prior quarter, both due to the lower overall volumes.

Production segment expenses were $273.3 million, up 12% from the prior quarter and 47% from the first quarter of 2025. The increase from the prior quarter was primarily due to higher volumes in direct lending, increased capacity and seasonal factors. The increase from the first quarter of 2025 was primarily due to higher volumes in direct lending and increased capacity.

Servicing Segment

The Servicing segment includes income from owned MSRs and subservicing. The total servicing portfolio decreased to $720.3 billion in UPB at March 31, 2026, down 2% from December 31, 2025 and up 6% from March 31, 2025. PFSI’s owned MSR portfolio totaled $483.8 billion in UPB, an increase of 3% from December 31, 2025 and 8% from March 31, 2025. PFSI subservices $236.5 billion in UPB, down 10% from the prior quarter. The decrease was driven by the transfer of $24 billion in UPB of MSR sold in the prior quarter. Of total subservicing UPB, $225.1 billion was for PMT, and $11.4 billion was for non-affiliates.

The table below details PFSI’s servicing portfolio UPB:

Servicing segment pretax income was $12.7 million, down from $37.3 million in the prior quarter and $76.0 million in the first quarter of 2025. Servicing segment net revenues totaled $125.1 million, down from $153.9 million in the prior quarter and $170.6 million in the first quarter of 2025.

Revenue from net loan servicing fees totaled $152.8 million, up from $149.8 million in the prior quarter and down from $164.3 million in the first quarter of 2025. Net loan servicing fee revenues included $532.1 million in loan servicing fees, essentially unchanged from the prior quarter. Realization of cash flows was $355.0 million in the first quarter, down 7% from the prior quarter, reflecting the expectation of lower prepayment speeds in the future from portfolio burnout. Net MSR valuation-related losses totaled $24.3 million, comprised of MSR fair value gains of $183.0 million and hedging losses of $207.3 million.

The following table presents a breakdown of net loan servicing fees:

Servicing segment revenue included $33.8 million in net gains on loans held for sale related to early buyout loans (EBOs), up from $25.5 million in the prior quarter and essentially unchanged from $33.9 million in the first quarter of 2025. The increase from the prior quarter reflects higher initiation volumes and redelivery margins as a result of lower rates in the beginning of the quarter. These EBOs are previously delinquent loans that were brought back to performing status through PFSI’s successful servicing efforts.

Net interest expense totaled $59.2 million, compared to $19.2 million in the prior quarter and $27.4 million in the first quarter of 2025. Interest income was $94.9 million, down from $134.6 million in the prior quarter due primarily to lower short-term interest rates and the reversal of principal-only stripped MBS accretion due to slower expected future runoff. Interest expense was $154.1 million, up slightly from $153.8 million in the prior quarter.

Servicing segment expenses totaled $112.4 million, down from $116.6 million in the prior quarter primarily due to a decrease in provisions for losses on active loans.

Corporate and Other

Corporate and Other items include amounts attributable to corporate activities or not directly attributable to the production and servicing segments as well as management fees earned from PMT. PFSI manages PMT for which it earns base management fees and may earn performance incentive fees.

Pretax loss for Corporate and Other was $41.5 million, up from $30.2 million in the prior quarter and $33.7 million in the first quarter of 2025.

Corporate and Other net revenues totaled $13.0 million, and consisted of $6.8 million in management fees, $6.0 million in other revenue, and $0.3 million of net interest income. No performance incentive fees were earned in the first quarter.

Expenses were $54.5 million, up from $43.4 million in the prior quarter and $46.1 million in the first quarter of 2025. The increase from the prior quarter was primarily driven by higher advertising expenses related to the 2026 Winter Olympics, as well as $3.2 million of expenses associated with the Cenlar acquisition. The prior quarter also included reduced expenses related to technology accruals.

The following table presents a breakdown of management fees:

Consolidated Expenses

Total expenses were $440.3 million, up from $403.6 million in the prior quarter due to higher expenses in the production and corporate and other segments as mentioned above.

Taxes

PFSI recorded a provision for tax expense of $22.4 million, resulting in an effective tax rate of 21.4%.
