Golub Capital Private Credit Fund August 2026 Shareholder Letter Dear Shareholder, We are pleased to report that Golub Capital Private Credit Fund (“GCRED” or “the Fund”) generated an 8.9% annualized inception-to-date net return to shareholders through June 30, 2026. Furthermore, repurchase requests in the tender period closing on July 29, 2026 decreased to 4.8% of common shares outstanding as of March 31, 2026 (down from 8.5% on a comparable basis in the prior quarter). GCRED is intentionally structured with a quarterly share repurchase limitation of 5.0% of our common shares outstanding. Repurchase requests for the tender period ending July 29, 2026 were below the 5.0% that were offered. As a result, 100% of repurchase requests will be honored in full at a price equal to the net asset value as of June 30, 2026. Consistent with last quarter’s tender offer, the repurchase requests were concentrated in a small subset representing approximately 5% of GCRED’s more than 12,000 shareholders. Importantly, the Fund maintains meaningful and diversified sources of liquidity of approximately $4 billion as of June 30, 2026, and we expect to maintain sufficient liquidity to continue our repurchase program for the foreseeable future.1 The Fund had new subscriptions totaling approximately 17.7 million shares year-to-date through July 29, 2026. We believe that GCRED is well positioned for the current environment due to its carefully constructed, well-performing, diversified portfolio and its access to the experience and resources of the Golub Capital platform. As of June 30, 2026, GCRED’s portfolio consists of over $9.6 billion in total investments at fair value. Loans are predominately first lien senior secured (approximately 96% of the portfolio) with strong downside protection, as evidenced by an average loan-to-value ratio of 45%. The portfolio remains well diversified with exposure to 454 individual portfolio companies and average position size of 0.2%. GCRED’s investment portfolio continues to perform well, as measured by our internal performance ratings. As of June 30, 2026, approximately 97% of investments were in rating categories 4 and 5—our strongest internal performance ratings, which indicates that borrowers are performing at or above expectations. GCRED had no debt investments rated in category 1 (highest risk). In addition, 0.1% of GCRED’s investment portfolio (at fair value) was on non-accrual, a metric that remains significantly below industry averages.2 We believe these indicators reflect the strength and stability of GCRED’s portfolio. Going forward our playbook remains unchanged: maintain rigorous underwriting standards, identify underperformance early, work proactively with sponsors, and stay prepared to lean in when attractive opportunities emerge. This disciplined approach has helped Golub Capital minimize realized losses and deliver consistent results historically, and we believe it will serve GCRED well in the coming period. Sincerely, Golub Capital Private Credit Fund 1

Accordingly, the terms and provisions included herein are presented as of the dates indicated and information about the fund in its final form may differ materially from the information set forth herein. − Alternative investments often are speculative, typically have higher fees than traditional investments, often include a high degree of risk and are suitable only for eligible, long-term investors who are willing to forgo liquidity and put capital at risk for an indefinite period of time. They may be highly illiquid and can engage in leverage and other speculative practices that may increase volatility and risk of loss. − Highly Competitive Market for Investment Opportunities. The activity of identifying, completing and realizing attractive investments is highly competitive, and involves a high degree of uncertainty. There can be no assurance that the Fund will be able to locate, consummate and exit investments that satisfy its objectives or realize upon their values or that the Fund will be able to fully invest its committed capital.

In connection with other activities of Golub Capital, certain Golub Capital personnel may acquire confidential or material non-public information or be restricted from initiating transactions in certain securities, including on the Fund’s behalf. As such, the Fund may not be able to initiate a transaction or sell an investment. In addition, policies and procedures maintained by Golub Capital to deter the inappropriate sharing of material non-public information may limit the ability of Golub Capital personnel to share information with personnel in Golub Capital’s other business groups, which may ultimately reduce the positive synergies expected to be realized by the Fund as part of the broader Golub Capital investment platform.

Golub Capital Private Credit Fund | August 2026 Shareholder Letter 4 Summary of Risks − We are a relatively new company with a limited operating history and there is no assurance that we will achieve our investment objective. − The majority of our portfolio investments are valued using the investment’s fair value, as determined in good faith by our valuation designee, subject to oversight by our Board of Trustees, and, as a result, there could be uncertainty as to the value of our portfolio investments. − Because subscriptions must be submitted at least five business days prior to the first calendar day of each month (unless waived), you will not know the net asset value per share at which you will be subscribing at the time you subscribe. − You should not expect to be able to sell your Common Shares regardless of how we perform. − You should not expect to have access to the money you invest for an extended period of time. − We do not intend to list our Common Shares on any securities exchange, and we do not expect a secondary market in our Common Shares to develop prior to any listing. − Because you should not expect to be able to sell your Common Shares, you should not expect to be able to reduce your exposure in any market downturn. − At the discretion of our Board of Trustees, we have commenced a quarterly share repurchase program, but only a limited number of Common Shares will be eligible for repurchase and repurchases will be subject to available liquidity, among other significant restrictions. Our Board of Trustees may amend, suspend or terminate the share repurchase program upon 30 days’ notice, if it deems such action to be in our best interest and the best interest of our shareholders. As a result, we cannot guarantee that share repurchases will be made available each quarter. − An investment in our Common Shares is not suitable for you if you need access to the money you invest. − You will bear substantial fees and expenses in connection with your investment. − Because the incentive fee is based on the performance of our portfolio, the Investment Adviser may be incentivized to make investments on our behalf that are riskier or more speculative than would be the case in the absence of such compensation arrangement. − We cannot guarantee that we will make distributions, and if we do, we may fund such distributions from sources other than cash flow from operations, including the sale of assets, borrowings, return of capital or offering proceeds, and although we generally expect to fund distributions from cash flow from operations, we have not established limits on the amounts we may pay from such sources. Any capital returned through distributions will be returned after the payment of fees and expenses. − Distributions may also be funded in significant part, directly or indirectly, from temporary waivers or expense reimbursements borne by the Investment Adviser or its affiliates, that may be subject to reimbursement to the Investment Adviser or its affiliates. The repayment of any amounts owed to our affiliates will reduce future distributions to which you would otherwise be entitled. − We use and expect to continue to use leverage, which will magnify the potential for loss on amounts invested in us. − We invest in securities that are rated below investment grade by independent rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal. They may also be illiquid and difficult to value. − Neither the U.S. Securities and Exchange Commission nor any state securities regulator has approved or disapproved of these securities or determined if the Prospectus is truthful or complete. Any representation to the contrary is a criminal offense. Securities regulators have also not passed upon whether this offering can be sold in compliance with existing or future suitability or conduct standards including the ‘Regulation Best Interest’ standard to any or all purchasers. − This letter must be read in conjunction with the Prospectus in order to fully understand all the implications and risks of an investment in GCRED. This letter is neither an offer to sell nor a solicitation of an offer to buy securities. An offering is made only by the Prospectus. Prior to making an investment, investors should read the Prospectus, including the “Risk Factors” section therein, which contain the risks and uncertainties that we believe are material to our business’ operating results.
