MORGAN STANLEY PRIVATE CREDIT | INVESTOR UPDATE | SEPTEMBER 2026

Dear Investor,

Thank you for your continued investment in North Haven Private Income Fund A LLC (“PIF A” or the “Company”) and for your ongoing trust in Morgan Stanley Private Credit. We are writing to provide an update on the Company and the results of its most recent quarterly unit repurchase offer.

In connection with the third quarter repurchase offer, the Company received repurchase requests representing approximately 6.8%⁽¹⁾ of units outstanding as of June 30, 2026. Consistent with prior quarters and as disclosed in the Company’s offer to purchase, 5.0% of outstanding units⁽²⁾ will be repurchased on a prorated basis, at a price equal to the net asset value (“NAV”) per unit as of September 30, 2026, with approximately 73.3%⁽³⁾ of each investor’s tender request fulfilled.

Notably, over two thirds of repurchase requests for the quarter are associated with unitholders whose repurchase requests were prorated in the prior two repurchase offers. We believe the composition and stabilization of request activity may indicate the durability of the Company’s investor base. Upon completion of this quarter’s repurchases, investors who sought full tender of their units during the prior two repurchase offers will have received more than 95% of their requested tendered amount.⁽⁴⁾

After accounting for new subscriptions and dividend reinvestments, the estimated net impact of the tenders on the Company’s NAV is approximately $8.2⁽⁵⁾ million, representing approximately 2.8%⁽⁶⁾ of the Company’s NAV on June 30, 2026.

In addition to prudent capital deployment, maintaining a disciplined capital structure and stable leverage profile remain core priorities. PIF A repurchased units with an aggregate value of approximately $45 million across three repurchase periods ending September 30, 2026, while maintaining leverage at the low end of its target range and preserving substantial available liquidity. As of July 31, 2026, the Company’s debt-to-NAV ratio remained stable at 1.04x. We believe PIF A remains well positioned from a liquidity and capital management perspective with more than $240 million in undrawn debt capacity and cash as of July 31, 2026. In addition, the combination of portfolio cash flows, repayment activity, and more than $45 million of liquid loans support the Company’s ability to selectively deploy capital while maintaining flexibility to meet repurchase obligations.

The Company’s unit repurchase framework is designed to provide investors with periodic liquidity, while aligning with the inherently less liquid nature of the Company’s underlying investments and positioning the portfolio to capture attractive opportunities as they arise. We believe that PIF A and the broader Morgan Stanley Private Credit platform remain well positioned due to our scale, strong sourcing capabilities, diligent underwriting, active portfolio management and patient capital base.

We continue to observe constructive market conditions, including improved lending terms and healthy sponsor activity as compared to the start of the year, along with broadly stable credit fundamentals across the portfolio. We are also seeing a rally in broadly syndicated loans, with particular rebound in software-related credits. We believe these trends suggest a more constructive and improving market environment compared with the more uncertain conditions that characterized the start of the year.

We remain focused on managing the Company with discipline, transparency, and a long-term perspective, and we thank you for your continued partnership.

Sincerely,

Morgan Stanley Private Credit

On behalf of North Haven Private Income Fund A Management Team
