(the issuer) is an arbitrage cash flow collateralized loan obligation (CLO) that will be managed by Golub Capital LLC. Net proceeds from the issuance of the secured and subordinated notes will provide financing on a portfolio of approximately $400 million of primarily first lien senior secured leveraged loans.KEY RATING DRIVERSAsset Credit Quality: The average credit quality of the indicative portfolio is 'B', which is in line with that of recent CLOs. The weighted average rating factor (WARF) of the indicative portfolio is 24.19 and will be managed to a WARF covenant from a Fitch test matrix. Issuers rated in the 'B' rating category denote a highly speculative credit quality; however, the notes benefit from appropriate credit enhancement and standard U.S. CLO structural features.Asset Security: The indicative portfolio consists of 100% first lien senior secured loans. The weighted average recovery rate (WARR) of the indicative portfolio is 77.17% and will be managed to a WARR covenant from a Fitch test matrix.Portfolio Composition: The largest three industries may comprise up to 45.5% of the portfolio balance in aggregate while the top five obligors can represent up to 12.5% of the portfolio balance in aggregate. The level of diversity resulting from the industry, obligor and geographic concentrations is in line with other recent CLOs.Portfolio Management: The transaction has a 5.1-year reinvestment period and reinvestment criteria similar to other CLOs. Fitch's analysis was based on a stressed portfolio created by adjusting the indicative portfolio to reflect permissible concentration limits and collateral quality test levels.Cash Flow Analysis: Fitch used a customized proprietary cash flow model to replicate the principal and interest waterfalls and assess the effectiveness of various structural features of the transaction. In Fitch's stress scenarios, the rated notes can withstand default and recovery assumptions consistent with their assigned ratings.The WAL used for the transaction stress portfolio and matrices analysis is 12 months less than the WAL covenant to account for structural and reinvestment conditions after the reinvestment period. In Fitch's opinion, these conditions would reduce the effective risk horizon of the portfolio during stress periods.RATING SENSITIVITIES Factors that Could, Individually or Collectively, Lead to Negative Rating Action/DowngradeVariability in key model assumptions, such as decreases in recovery rates and increases in default rates, could result in a downgrade. Fitch evaluated the notes' sensitivity to potential changes in such a metric. The results under these sensitivity scenarios are as severe as between 'BBB+sf' and 'AA+sf' for class A-1, between 'BBB+sf' and 'AA+sf' for class A-2, between 'BB+sf' and 'A+sf' for class B, between 'Bsf' and 'BBB+sf' for class C, between less than 'B-sf' and 'BB+sf' for class D-1, between less than 'B-sf' and 'BB+sf' for class D-2, and between less than 'B-sf' and 'B+sf' for class E.Factors that Could, Individually or Collectively, Lead to Positive Rating Action/UpgradeUpgrade scenarios are not applicable to the class A-1 and class A-2 notes as these notes are in the highest rating category of 'AAAsf'.Variability in key model assumptions, such as increases in recovery rates and decreases in default rates, could result in an upgrade. Fitch evaluated the notes' sensitivity to potential changes in such metrics; the minimum rating results under these sensitivity scenarios are 'AAAsf' for class B, 'AA+sf' for class C, 'A+sf' for class D-1, 'A-sf' for class D-2, and 'BBB+sf' for class E.USE OF THIRD PARTY DUE DILIGENCE PURSUANT TO SEC RULE 17G -10Form ABS Due Diligence-15E was not provided to, or reviewed by, Fitch in relation to this rating action.Date of Relevant Committee 03 December 2025 REFERENCES FOR SUBSTANTIALLY MATERIAL SOURCE CITED AS KEY DRIVER OF RATING The principal sources of information used in the analysis are described in the Applicable Criteria.

In issuing and maintaining its ratings and in making other reports (including forecast information), Fitch relies on factual information it receives from issuers and underwriters and from other sources Fitch believes to be credible. Fitch conducts a reasonable investigation of the factual information relied upon by it in accordance with its ratings methodology, and obtains reasonable verification of that information from independent sources, to the extent such sources are available for a given security or in a given jurisdiction. The manner of Fitch’s factual investigation and the scope of the third-party verification it obtains will vary depending on the nature of the rated security and its issuer, the requirements and practices in the jurisdiction in which the rated security is offered and sold and/or the issuer is located, the availability and nature of relevant public information, access to the management of the issuer and its advisers, the availability of pre-existing third-party verifications such as audit reports, agreed-upon procedures letters, appraisals, actuarial reports, engineering reports, legal opinions and other reports provided by third parties, the availability of independent and competent third- party verification sources with respect to the particular security or in the particular jurisdiction of the issuer, and a variety of other factors. Users of Fitch’s ratings and reports should understand that neither an enhanced factual investigation nor any third-party verification can ensure that all of the information Fitch relies on in connection with a rating or a report will be accurate and complete. Ultimately, the issuer and its advisers are responsible for the accuracy of the information they provide to Fitch and to the market in offering documents and other reports. In issuing its ratings and its reports, Fitch must rely on the work of experts, including independent auditors with respect to financial statements and attorneys with respect to legal and tax matters. Further, ratings and forecasts of financial and other information are inherently forward-looking and embody assumptions and predictions about future events that by their nature cannot be verified as facts. As a result, despite any verification of current facts, ratings and forecasts can be affected by future events or conditions that were not anticipated at the time a rating or forecast was issued or affirmed.The information in this report is provided “as is” without any representation or warranty of any kind, and Fitch does not represent or warrant that the report or any of its contents will meet any of the requirements of a recipient of the report. A Fitch rating is an opinion as to the creditworthiness of a security. This opinion and reports made by Fitch are based on established criteria and methodologies that Fitch is continuously evaluating and updating. Therefore, ratings and reports are the collective work product of Fitch and no individual, or group of individuals, is solely responsible for a rating or a report. The rating does not address the risk of loss due to risks other than credit risk, unless such risk is specifically mentioned. Fitch is not engaged in the offer or sale of any security. All Fitch reports have shared authorship. Individuals identified in a Fitch report were involved in, but are not solely responsible for, the opinions stated therein. The individuals are named for contact purposes only. A report providing a Fitch rating is neither a prospectus nor a substitute for the information assembled, verified and presented to investors by the issuer and its agents in connection with the sale of the securities. Ratings may be changed or withdrawn at any time for any reason in the sole discretion of Fitch. Fitch does not provide investment advice of any sort. Ratings are not a recommendation to buy, sell, or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax-exempt nature or taxability of payments made in respect to any security. Fitch receives fees from issuers, insurers, guarantors, other obligors, and underwriters for rating securities. Such fees generally vary from US$1,000 to US$750,000 (or the applicable currency equivalent) per issue. In certain cases, Fitch will rate all or a number of issues issued by a particular issuer, or insured or guaranteed by a particular insurer or guarantor, for a single annual fee. Such fees are expected to vary from US$10,000 to US$1,500,000 (or the applicable currency equivalent). The assignment, publication, or dissemination of a rating by Fitch shall not constitute a consent by Fitch to use its name as an expert in connection with any registration statement filed under the United States securities laws, the Financial Services and Markets Act of 2000 of the United Kingdom, or the securities laws of any particular jurisdiction. Due to the relative efficiency of electronic publishing and distribution, Fitch research may be available to electronic subscribers up to three days earlier than to print subscribers.For Australia, New Zealand, Taiwan and South Korea only: Fitch Australia Pty Ltd holds an Australian financial services license (AFS license no. 337123) which authorizes it to provide credit ratings to wholesale clients only.

While certain of the NRSRO’s credit rating subsidiaries are listed on Item 3 of Form NRSRO and as such are authorized to issue credit ratings on behalf of the NRSRO (see https://www.fitchratings.com/site/regulatory), other credit rating subsidiaries are not listed on Form NRSRO (the “non-NRSROs”) and therefore credit ratings issued by those subsidiaries are not issued on behalf of the NRSRO.
