(1)MSRs transferred in transactions which do not qualify for sale accounting treatment. Until such time as the transaction qualifies as a sale for accounting purposes, we continue to recognize the MSRs and the related financing liability (referred as Pledged MSR liability) on our consolidated balance sheets, as well as the full amount of servicing fee collected as revenue and the servicing fee remitted as Pledged MSR liability expense in our consolidated statements of operations. The fair value of the Pledged MSR liability may differ from the fair value of the associated transferred MSR asset mostly due to the portion of ancillary income that is contractually retained by PHH or other contractual cash flows. (2)Consists of the obligation to remit to third parties a specified percentage of future servicing fee collections (servicing spread) on reference pools of MSRs, which we are entitled to as owner of the related MSRs. The servicing spread remittance is reported in Pledged MSR liability expense and fair value gains and losses of the ESS financing liability are reported in MSR valuation adjustment, net - See Note 9 – MSR Valuation Adjustments, Net. The following table presents the activity of the Other financing liabilities, at fair value that are classified as Level 3 within the valuation hierarchy.

(1)During the three months ended June 30, 2024, we derecognized a portion of the MAV Pledged MSR liability upon sale of the related MSRs by MAV to a third party with a UPB of $5.5 billion. The following table presents the Pledged MSR liability expense recorded in connection with the MSR sale agreements with MAV, Rithm, and others that do not qualify for sale accounting, including the ESS financing liabilities.

(1) The information related to Rithm in the above tables relates to the MSR portfolio, referred to as Rights to MSRs (or RMSR), that does not qualify for sale accounting and represented $8.5 billion of UPB as of September 30, 2025 - see below discussion. Other subservicing agreements with Rithm are not reflected in the above table. MAV (Related Party) Transactions PHH entered into agreements to sell MSR portfolios to its related party MAV, on a bulk and flow basis, for which PHH has been retained as subservicer. While MSR legal title has transferred to MAV, the transactions do not qualify for sale accounting treatment primarily due to the termination restrictions of the subservicing agreement. Accordingly, we continue to report the MSR and an associated Pledged MSR liability on our consolidated balance sheet. Rithm Transactions Starting in 2012, Onity and PHH entered into agreements to sell MSRs and the related servicing advances to Rithm, for which PHH has been retained as subservicer. As of September 30, 2025, all transactions met sale accounting treatment except for the agreement to sell an $8.5 billion MSR portfolio to Rithm, referred to as Rights to MSRs (or RMSR). While most of the economics and risks of the MSR and related advances have contractually transferred to Rithm, the MSR legal title was retained by Onity and the third-party consents required for title transfer were not obtained, causing the transactions to be accounted for as secured financings. Accordingly, we continue to report the $108.1 million MSR and an associated Pledged MSR liability on our consolidated balance sheet (the remaining is treated as subservicing). The RMSR agreement and subservicing agreements are subject to automatic one-year renewals, unless Onity provides seven months’ advance notice of termination, or Rithm provides three months’ advance notice of termination. In November 2024, Onity and Rithm agreed to extend the subservicing agreements through February 1, 2026, with subsequent, automatic one-year renewals if notice of termination is not provided by July 1, 2026 by Onity or November 1, 2025 by Rithm. Also refer to Note 21 — Commitments, Client Concentration and Note 23 – Subsequent Events. If Rithm exercises its termination right of the $8.5 billion RMSR agreement, Rithm has the option of seeking (i) the transfer of the MSRs through a sale to a third party of its Rights to MSRs (together with a transfer of Onity’s title to those MSRs) or (ii) a substitute RMSR arrangement that substantially replicates the Rights to MSRs structure under which we would transfer title to the MSRs to a successor servicer and Rithm would continue to own the economic rights and obligations related to the MSRs. In the case of option (i), we have a purchase option as specified in the RMSR Agreements. If Rithm is not able to sell the Rights to MSRs or establish a substitute RMSR arrangement with another servicer, Rithm has the right to revoke its termination notice and re-instate the applicable servicing addendum or to establish a subservicing arrangement whereby the MSRs remaining subject to the RMSR Agreements would be transferred to up to three subservicers who would subservice under Onity’s oversight. If such a subservicing arrangement were established, Onity would receive an oversight fee and reimbursement of expenses. We may also agree on alternative arrangements that are not contemplated under our existing agreements or that are variations of those contemplated under our existing agreements. Other MSR Capital Partner Transactions PHH entered into agreements to sell MSR portfolios to different unrelated third parties, referred to as MSR capital partners, on a bulk and flow basis, for which PHH has been retained as subservicer. While MSR legal title has transferred to the MSR capital partners, the transactions do not qualify for sale accounting treatment primarily due to the termination restrictions of the subservicing agreements. Accordingly, we continue to report the MSR and an associated Pledged MSR liability on our consolidated balance sheet.
