          On October 29, 2025 (the "Closing Date"), Apollo Debt Solutions BDC (the "Company") completed a $702,200,000 term debt securitization (the "2025 Debt Securitization"). Term debt securitizations are also known as collateralized loan obligations and are a form of secured financing incurred by a subsidiary of the Company, which is consolidated by the Company and subject to the Company's overall asset coverage requirements.
        
        
          On the Closing Date and in connection with the 2025 Debt Securitization, ADL CLO 2 LLC (the "CLO Issuer"), an indirect, wholly-owned, consolidated subsidiary of the Company, entered into a placement agency agreement (the "CLO Placement Agreement") with RBC Capital Markets, LLC, as the placement agent (the "Placement Agent") and Apollo Global Securities, LLC, as 
          
            co-placement
          
          agent (the 
          
            "Co-Placement
          
          Agent"), pursuant to which the Placement Agent and the 
          
            Co-Placement
          
          Agent agreed to place certain of the notes issued by the CLO Issuer as part of the 2025 Debt Securitization pursuant to an indenture by and between the CLO Issuer and U.S. Bank Trust Company, National Association, as collateral trustee (the "CLO Indenture").
        
          The notes issued as part of the 2025 Debt Securitization consist of $0 of AAA(sf) Class A-1a Senior Secured Floating Rate Notes due 2037, which bear interest at the three-month secured overnight financing rate published by the Federal Reserve Bank of New York ("SOFR") plus 1.45% (the "Class A-1a Notes"); $14,000,000 of AAA(sf) Class A-1b Senior Secured Floating Rate Notes due 2037, which bear interest at the three-month SOFR plus 1.65% (the "Class A-1b Notes"); $30,000,000 of AA(sf) Class A-2 Senior Secured Floating Rate Notes due 2037, which bear interest at the three-month SOFR plus 1.85% (the "Class A-2 Notes"); $56,000,000 of A(sf) Class B Secured Deferrable Floating Rate Notes due 2037, which bear interest at the three-month SOFR plus 2.20% (the "Class B Notes"); $42,000,000 of BBB-(sf) Class C Secured Deferrable Floating Rate Notes due 2037, which bear interest at the three-month SOFR plus 3.20% (the "Class C Notes" and together with the Class A-1a Notes, the Class A-1b Notes, the Class A-2 Notes and the Class B Notes, the "Secured Notes"). Additionally, on the Closing Date, the CLO Issuer will issue $128,200,000 of Subordinated Notes due 2125 (the "Subordinated Notes"), which do not bear interest. The Secured Notes together with the Subordinated Notes are collectively referred to herein as the "Notes".
        
        
          Additionally, the CLO Issuer incurred certain loans as part of the 2025 Debt Securitization, consisting of $398,500,000 of AAA(sf) 
          
            Class A-1a-L1
          
          Loans due 2037, which bear interest at the three-month SOFR plus 1.45% (the 
          
            "Class A-1a-L1
          
          Loans"); $7,500,000 of AAA(sf) 
          
            Class A-1a-L2
          
          Loans due 2037, which bear interest at the three-month SOFR plus 1.45% (the 
          
            "Class A-1a-L2
          
          Loans"); $14,000,000 of A
          
            A
          
          A(sf) 
          
            Class A-1b
          
          Loans due 2037, which bear interest at the three-month SOFR plus 1.65% (the 
          
            "Class A-1b
          
          Loans"); and $12,000,000 of AA(sf) 
          
            Class A-2
          
          Loans due 2037, which bear interest at the three-month SOFR plus 1.85% (the 
          
            "Class A-2
          
          Loans", and together with the 
          
            Class A-1a-L1
          
          Loans, the 
          
            Class A-1a-L2
          
          Loans and the

          Loans, the "Loans" and the Loans together with the Secured Notes, the "Secured Debt" and Secured Debt together with the Subordinated Notes, the "Debt") incurred by the CLO Issuer on the Closing Date. The

          Loans were incurred pursuant to a

          Credit Agreement among the CLO Issuer, as borrower, U.S. Bank Trust Company, National Association, as loan agent and collateral trustee and the lenders party thereto (the 
          
            "Class A-1a-L1
          
          Credit Agreement"), (ii)

          Loans were incurred pursuant to a

          Credit Agreement among the CLO Issuer, as borrower, U.S. Bank Trust Company, National Association, as loan agent and collateral trustee and the lenders party thereto (the 
          
            "Class A-1a-L2
          
          Credit Agreement"), (iii) 
          
            Class A-1b
          
          Loans were incurred pursuant to a 
          
            Class A-1b
          
          Credit Agreement among the CLO Issuer, as borrower, U.S. Bank Trust Company, National Association, as loan agent and collateral trustee and the lenders party thereto (the 
          
            "Class A-1b
          
          Credit Agreement"), and 
          
            (iv) Class A-2
          
          Loans were incurred pursuant to a 
          
            Class A-2
          
          Credit Agreement among the CLO Issuer, as borrower, U.S. Bank Trust Company, National Association, as loan agent and collateral trustee and the lenders party thereto (the 
          
            "Class A-2
          
          Credit Agreement" and together with the 
          
            Class A-1a-L1
          
          Credit Agreement, the 
          
            Class A-1a-L2
          
          Credit Agreement and the 
          
            Class A-1b
          
          Credit Agreement, the "CLO Credit Agreements").
        
          The 2025 Debt Securitization is backed by a diversified portfolio consisting primarily of first-lien commercial loans. The Secured Debt is scheduled to mature on October 15, 2037 and the Subordinated Notes are scheduled to mature on October 15, 2125; however, the Debt may be redeemed by the CLO Issuer, at the direction of ADL CLO 2 Depositor LLC (the "CLO Retention Holder"), a wholly-owned, consolidated subsidiary of the Company, as owner of a majority of the Subordinated Notes, on any business day on or after October 15, 2027. The CLO Retention Holder acts as retention holder in connection with the 2025 Debt Securitization for the purposes of satisfying certain U.S. regulations requiring sponsors of securitization transactions to retain exposure to the performance of the securitized assets and as such is required to retain a portion of the Subordinated Notes. The Company, through the CLO Retention Holder, has retained 100% of the Class B Notes, the Class C Notes and the Subordinated Notes issued in the 2025 Debt Securitization.
        
       
      
        
          The CLO Issuer intends to use the proceeds from the 2025 Debt Securitization to, among other things, purchase certain loans ("Collateral Obligations") from time to time on and after the Closing Date from the Company pursuant to a master loan sale agreement entered into on the Closing Date (the "Loan Sale Agreement") among the Company, the CLO Retention Holder and the CLO Issuer. Under the terms of the Loan Sale Agreement that provide for the sale of Collateral Obligations to the CLO Issuer, the Company will transfer to the CLO Retention Holder, and the CLO Retention Holder will transfer to the CLO Issuer, a portion of its ownership interest in the Collateral Obligations securing the 2025 Debt Securitization for the purchase price and other consideration set forth in the Loan Sale Agreement from time to time on and after the Closing Date. Following these transfers, the CLO Issuer, and not the CLO Retention Holder or the Company, will hold all of the ownership interest in such loans and participations. The Company made customary representations, warranties and covenants in the Loan Sale Agreement.
        
        
          The Secured Debt is the secured obligation of the CLO Issuer, the Subordinated Notes are the unsecured obligations of the CLO Issuer, and the CLO Indenture and the CLO Credit Agreements governing the Debt include customary covenants and events of default. The Debt has not been, and will not be, registered under the Securities Act of 1933, as amended, or any state securities or "blue sky" laws and may not be offered or sold in the United States absent registration with the Securities and Exchange Commission or an applicable exemption from registration.
        
        
          The Company serves as collateral manager to the CLO Issuer under a collateral management agreement entered into on the Closing Date (the "Collateral Management Agreement"). Pursuant to the Collateral Management Agreement, so long as the Company is the collateral manager, the collateral management fee will equal 0.0% per annum of the fee basis amount.
