Q1 2026 Risk Rating Risk Rating 1 Borrower is operating above expectations, and the trend and risk factors are generally favorable. 2 Borrower is operating generally as expected or at an acceptable level of performance. The level of risk to our initial cost basis is similar to the risk at the time of origination. This is the initial risk rating assigned to all new borrowers and the gradations of 2 are internal only. 3 Borrower is operating below expectations and the level of risk to our cost basis has increased since the time of origination. The borrower may be out of compliance with debt covenants. Payments are generally current although there may be a higher risk of payment default. 4 Borrower is operating materially below expectations and the loan's risk has increased materially since origination. In addition to the borrower being generally out of compliance with debt covenants, loan payments may be past due, but generally not more than 120 days. It is anticipated that we may not recoup our initial cost basis and may realize a loss of our initial cost basis upon exit. 5 Borrower is operating substantially below expectations and the loan's risk has increased substantially since origination. Most or all of the debt covenants are out of compliance and payments are substantially delinquent. It is anticipated that we will not recoup our initial cost basis and may realize a substantial loss of our initial cost basis upon exit.

Disclaimer and Risk Factors (Cont’d) Select Risk Factors: An investment in any securities offered by any client managed by AGL is suitable only for sophisticated investors and requires the financial ability and willingness to accept the risks and lack of liquidity that are characteristic of an investment in such securities. Investors in the securities must be prepared to bear such risks for an extended period of time. This presentation expresses no views as to the suitability of an investment in such securities to the institutional investor's entire portfolio or individualized circumstances of such recipients. In particular, the risks of investing in any securities offered by any client managed by AGL could include the following: Lack of liquidity in that there is no secondary market for such securities, and none is expected to develop; Restrictions on transferring interests in such securities; The use of leverage at the level of the ultimate investment; Potential lack of diversification and resulting higher risk; Absence of information regarding valuations and pricing of the investments backing such securities because investments are in private companies; and The investment structure through which the issuer of such securities invests. This is not intended to be a complete description of the risks of investing in any securities offered by any client managed by AGL. Investors should rely on their own examination of the potential risks and rewards. The private placement memorandum and/or other documents describing any such securities discuss these and other important risk factors and considerations that should be carefully evaluated before making an investment in such securities. Prospective investors should consult with their own legal, tax and financial advisers as to the consequences of an investment in such securities. While AGL has prior operating history as an asset manager, AGL’s collaboration with Barclays represents an expansion in that it includes a newly established team with a limited operating history as an investment adviser and AGL’s new products have initially relied in significant part on Barclays pipeline of investment opportunities, which might or might not be able to source the anticipated quantity or quality of opportunities in the future. There is no assurance that such new business endeavors will become successful. Additionally, clients could continue to invest in other newly established or early-stage asset management businesses in transactions designed to provide capital to such business, which could experience unexpected operational, developmental or financial issues that cannot be adequately resolved, and there is no assurance that such new business ventures will become successful. Newly established businesses are often more vulnerable to financial failure than more established entities with longer track records. There is no assurance that the development efforts of any such business will be successful or, if successful, will be completed within budget or the time period originally estimated. © 2026 AGL CREDIT MANAGEMENT LLC.
