Net Gains (Losses) on Investments and Financings

Net gains (losses) on investments and financings are summarized below:

The increase in net gains on investments for the quarter and six months ended June 30, 2025, as compared to the same periods in 2024, was primarily due to gains from our investments in MBS as interest rates were stable or decreased in 2025 and increased in the same periods in 2024.

During the quarter and six months ended June 30, 2025, we recognized net valuation gain of $14.6 million and $79.4 million, respectively, as compared to valuation losses of $34.9 million and $73.1 million for the same periods in 2024. The gain recognized reflects stable or decreasing interest rates during the quarter and six months ended June 30, 2025, as compared to increasing interest rates during the quarter and six months ended June 30, 2024.

Loans Held for Investment – Held in VIEs and Asset-backed Financings at Fair Value

Loans held for investment in VIEs and Asset-backed financings at fair value recorded a combined net valuation loss of $1.1 million and $1.9 million during the quarter and six months ended June 30, 2025, respectively, as compared to a valuation loss of $1.4 million and a valuation gain of $4.8 million during the quarter and six months ended June 30, 2024, respectively. The net loss during the quarter and six months ended June 30, 2025 reflects the losses on the asset-backed financing exceeding the gains on the underlying assets as the result of credit spread widening on our net investments secured by jumbo loans and investment properties, partially offset by the positive effect on fair value of decreasing interest rates. The net gain during the six months ended June 30, 2024 reflect the gains on the asset-backed financing exceeding the losses on the underlying assets as the result of credit spreads tightening on our net investments secured by jumbo loans and investment properties.

The activity in and balances relating to our CRT arrangements are summarized below:

(1)

Deposits securing credit risk transfer arrangements also secure $10.5 million and $4.1 million in CRT strip and CRT derivative liabilities at June 30, 2025 and December 31, 2024, respectively.

The performance of our investments in CRT arrangements during the six months ended June 30, 2025 reflects credit spread widening, as compared to the six months ended June 30, 2024, which reflected credit spread tightening.

Net Gains on Loans Acquired for Sale

Our net gains on loans acquired for sale are summarized below:

The changes in gain on loans acquired for sale during the quarter and six months ended June 30, 2025, as compared to the same periods in 2024, reflect the effect of increased loan production supplemented by increased gain on sale margins.

Non-cash elements of gain on sale of loans:

Interest Rate Lock Commitments

Our Net gains on loans acquired for sale include our estimates of gains or losses we expect to realize upon the sale of mortgage loans we have committed to purchase but have not yet purchased or sold. Therefore, we recognize a substantial portion of our net gains before we purchase the loans. These gains are reflected on our balance sheet as IRLC derivative assets and liabilities. We adjust the fair values of our IRLCs as the loan acquisition process progresses until we complete the acquisitions or the commitments are canceled. Such adjustments are included in our Net gains on loans acquired for sale. The fair values of our IRLCs become part of the carrying values of our loans when we complete the purchases of the loans. The methods and key inputs we use to measure the fair values of IRLCs are summarized in Note 7 – Fair value – Valuation Techniques and Inputs to the consolidated financial statements included in this Report.

The MSRs and liabilities for representations and warranties we recognize represent our estimate of the fair value of future benefits and costs we will realize for years in the future. These estimates change as circumstances change, and changes in these estimates are recognized in our results of operations in subsequent periods. Subsequent changes in the fair value of our MSRs significantly affect our results of operations.

The methods we use to measure and update the measurements of our MSRs as well as the effect of changes in valuation inputs on MSR fair value are detailed in Note 7 – Fair Value – Valuation Techniques and Inputs to the consolidated financial statements included in this Report.

Liability for Losses Under Representations and Warranties

We recognize liabilities for losses we expect to incur relating to the representations and warranties we provide to purchasers in our loan sales transactions. The representations and warranties we provide require adherence to purchaser and insurer origination and underwriting guidelines, including but not limited to the validity of the lien securing the loan, property eligibility, borrower credit, income and asset requirements, and compliance with applicable federal, state and local laws.

In the event of a breach of our representations and warranties, we may be required to either repurchase the loans with the identified defects, reimburse the investor for its loss or indemnify the investor or insurer against credit losses attributable to the loans with indemnified defects. In such cases, we bear any subsequent credit losses on the loans. Our credit losses may be reduced by any recourse we have to correspondent sellers that, in turn, had sold such loans to us and breached similar or other representations and warranties. In such event, we have the right to seek a recovery of those repurchase losses from that correspondent seller.

We recorded a provision for losses relating to representations and warranties relating to current period loan sales of $227,000 and $531,000 for the quarter and six months ended June 30, 2025, respectively, and $204,000 and $458,000 for the quarter and six months ended June 30, 2024, respectively.

Following is a summary of the indemnification, repurchase and loss activity and loans subject to representations and warranties:

The losses on representations and warranties we have recorded to date have been moderated by our ability to recover most of the losses inherent in the repurchased loans from the correspondent sellers. As the outstanding balance of loans we purchase and sell subject to representations and warranties increases, as the loans outstanding season, as our investors’ and guarantors’ loss mitigation strategies change and as our correspondent sellers’ ability and willingness to repurchase loans change, we expect that the level of repurchase activity and associated losses may increase.

The method we use to estimate the liability for representations and warranties is a function of our estimates of future defaults, loan repurchase rates, severities of loss in the event of default and the probabilities of reimbursement by the correspondent loan sellers. We establish a liability at our estimate of its fair value at the time loans are sold and review the adequacy of our recorded liability on a periodic basis.

The amount of the liability for representations and warranties is difficult to estimate and requires considerable judgment. The level of loan repurchase losses is dependent on economic factors, investor loss mitigation strategies, our ability to recover any losses inherent in the repurchased loan from the correspondent seller and other external conditions that change over the lives of the underlying loans. We may be required to incur losses related to such representations and warranties for several periods after the loans are sold or liquidated.

We record adjustments to our liability for losses on representations and warranties as economic fundamentals change, as investor and Agency evaluations of their loss mitigation strategies (including claims under representations and warranties) change and as economic conditions affect our correspondent sellers’ ability or willingness to fulfill their recourse obligations to us. Such adjustments may be material to our financial position and results of operations in future periods.

Adjustments to our liability for representations and warranties are included as a component of our Net gains on loans acquired for sale at fair value. We recorded a $912,000 and $2.1 million reduction in liability for representations and warranties during the quarter and six months ended June 30, 2025, respectively, compared to $6.5 million and $13.4 million for the quarter and six months ended June 30, 2024, respectively, due to the effects of certain loans reaching specified performance histories identified by the Agencies as sufficient to limit repurchase claims relating to such loans.

Loan Origination Fees

Loan origination fees represent fees we charge correspondent sellers relating to our purchase of loans from those sellers. Loan

origination fees increased during the quarter and six months ended June 30, 2025, as we purchased more loans for sale to nonaffiliates compared to the same periods in 2024.

Net Loan Servicing Fees

Our net loan servicing fees have two primary components: fees earned for servicing loans and the effects of MSR valuation changes, net of hedging results, as summarized below:

Loan Servicing Fees

Following is a summary of our loan servicing fees:

Loan servicing fees that relate to our MSRs are primarily related to servicing we provide for loans included in Agency securitizations. These fees are contractually established at an annualized percentage of the UPB of the loans serviced and we collect these fees from borrower payments. Other loan servicing fees are comprised primarily of borrower-contracted fees, such as late charges and reconveyance fees, as well as incentive fees we receive from the Agencies for loss mitigation activities and fees we charge to correspondent lenders for loans repaid by the borrower shortly after purchase.

The change in contractually-specified fees during the quarter and six months ended June 30, 2025 is due primarily to the slight reduction in our MSR servicing portfolio, reflecting the shift of a portion of our loan sales from sales to nonaffiliates with servicing rights retained to sales to PLS that include the transfer of servicing rights to PLS.

Mortgage Servicing Rights and Hedging

We have elected to carry our MSRs at fair value. Changes in fair value have two components: changes due to realization of the expected servicing cash flows and changes due to changes in the inputs used to estimate fair value. We endeavor to moderate the effects of changes in fair value attributable to changes in fair value inputs (market conditions) primarily by entering into derivative transactions.

Changes in fair value of MSRs and hedging results are summarized below:

Changes in fair value due to changes in valuation inputs used in our valuation model during the six months ended June 30, 2025 reflect the effects of expectations for faster future prepayments of the underlying loans due to decreases in interest rates during the six months ended June 30, 2025, compared to increasing interest rates during the same period in 2024.

The increase in loan recapture income from PFSI reflects the increase in refinancing activity in our MSR portfolio during the quarter and six months ended June 30, 2025, as compared to the same period in 2024. We have an agreement with PFSI that requires that when PFSI refinances a loan for which we held the MSRs, we receive a recapture fee. The MSR recapture agreement is summarized in Note 4 ‒Transactions with Related Parties – Operating Activities to the consolidated financial statements included in this Report.

Hedging results during the quarter and six months ended June 30, 2025 were primarily attributable to the impact of volatile interest rates and resulting elevated hedging costs, which were partially offset by fair value gains in Agency MBS.

Changes in realization of cash flows are influenced by changes in the level of servicing assets and liabilities and changes in estimates of remaining cash flows to be realized.

Following is a summary of our loan servicing portfolio by collection status:

Following is a summary of characteristics of the loans comprising our MSR servicing portfolio as of June 30, 2025:

Represents MSRs on conventional loans sold to private investors.

Net Interest Expense

Net interest expense is summarized below:

The effects of changes in the yields and costs and composition of our investments on our net interest expense are summarized below:

The decrease in net interest expense during the quarter and six months ended June 30, 2025, as compared to the same periods in 2024, is due to greater investment in interest earning assets net of financing supplemented by a reduction in cost of floating rate financing, partially offset by a decrease in earnings from placement fees relating to custodial funds managed for borrowers and investors.
