Amendment Description North Haven Private Income Fund LLC (the “Company”) is filing this Amendment No. 1 to the Annual Report on Form 10-K/A (the “Amendment”) solely for the purpose of correcting the signature in the Report of Independent Registered Public Accounting Firm (“Auditor Report”) included in Part II, Item 8 of the 10-K for the fiscal year ended December 31, 2025 as originally filed with the Securities and Exchange Commission (the “SEC”) on March 3, 2026 (the “Original Filing”). Accordingly, the Company is filing this Amendment to include a corrected Auditor Report. The error that was corrected includes the insertion of the conformed signature to the Auditor Report. The auditor’s opinion on the Company’s consolidated financial statements remained unchanged. The Auditor Report was included in the Original Filing. Except for the aforementioned correction to the signature in the Auditor Report, this Amendment does not amend, modify or update the Original Filing in any respect. Information included in this Amendment is stated as of December 31, 2025 and does not reflect events that have occurred subsequent to the filing of the Original Filing and, accordingly, this Amendment should be read in conjunction with our Original Filing made with the SEC.This Annual Report on Form 10-K/A consists of a cover page, this explanatory note, Item 8 (as amended) of the Annual Report on Form 10-K (including the consolidated financial statements and the corrected signature in the Auditor Report), Item 15, the signature page and the required certifications of the chief executive officer and the chief financial officer.
