Notes Offering

On September 25, 2025, North Haven Private Income Fund LLC (the “Company”) and U.S. Bank Trust Company, National Association (the “Trustee”) entered into a Second Supplemental Indenture (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) related to the Company’s issuance of $300,000,000 in aggregate principal amount of its 5.125% notes due 2028 (the “Notes”), which supplements the Base Indenture dated October 1, 2024 (the “Base Indenture”).

The Notes will mature on September 25, 2028 and may be redeemed in whole or in part at the Company’s option at any time prior to August 25, 2028 at par value plus a “make-whole” premium calculated in accordance with the terms of the Indenture and at par value on August 25, 2028 or thereafter. The Notes bear interest at a rate of 5.125% per year payable semi-annually on March 25 and September 25 of each year, commencing on March 25, 2026. The Notes are general unsecured obligations of the Company that rank senior in right of payment to all of the Company’s existing and future indebtedness that is expressly subordinated in right of payment to the Notes, rank pari passu with all existing and future unsecured unsubordinated indebtedness issued by the Company, rank effectively junior to any of the Company’s secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness, and rank structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company’s subsidiaries, financing vehicles or similar facilities.

The Indenture contains certain covenants, including covenants requiring the Company to comply with the asset coverage requirements of Section 18(a)(1)(A) as modified by Section 61(a)(1) and (2) of the Investment Company Act of 1940, as amended, whether or not it is subject to those requirements, and to provide financial information to the holders of the Notes and the Trustee if the Company is no longer subject to the reporting requirements under the Securities Exchange Act of 1934, as amended. These covenants are subject to important limitations and exceptions that are described in the Indenture.

In addition, on the occurrence of a “change of control repurchase event,” as defined in the Indenture, the Company will generally be required to make an offer to purchase the outstanding Notes at a price equal to 100% of the principal amount of such Notes plus accrued and unpaid interest to the repurchase date.

The foregoing description of the Second Supplemental Indenture does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Supplemental Indenture, filed as Exhibit 4.2 hereto and incorporated by reference herein.

The Notes were offered to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons outside the United States pursuant to Regulation S under the Securities Act (the “Notes Offering”). The Notes have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements. The Notes Offering closed on September 25, 2025. The net proceeds to the Company were approximately $294.6 million, after deducting the initial purchaser discount and estimated offering expenses. The Company expects to use the net proceeds of the Notes Offering to repay indebtedness, make investments in portfolio companies in accordance with its investment objectives and for the general corporate purposes of the Company and its subsidiaries.

In connection with the issuance of the Notes, the Company entered into interest rate swaps to more closely align the interest rates of the Company’s liabilities with the Company’s investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement related to the Notes, the Company receives a fixed interest rate of 5.383% per annum and pays a floating interest rate of SOFR + 2.0585% per annum on $300.0 million of the Notes. The Company designated each interest rate swap as the hedging instrument in a qualifying hedge accounting relationship.

Registration Rights Agreement

In connection with the Notes Offering, the Company entered into a Registration Rights Agreement, dated as of September 25, 2025 (the “Registration Rights Agreement”), with Wells Fargo Securities, LLC, BNP Paribas Securities Corp., ING Financial Markets LLC, J.P. Morgan Securities LLC and SMBC Nikko Securities America, Inc., as the representatives of the Initial Purchasers of the Notes. Pursuant to the Registration Rights Agreement, the Company is obligated to file with the Securities and Exchange Commission a registration statement relating to an

offer to exchange the Notes for new notes issued by the Company that are registered under the Securities Act and otherwise have terms substantially identical to those of the Notes, and to use its commercially reasonable efforts to cause such registration statement to be declared effective. If the Company is not able to effect the exchange offer, the Company will be obligated to file a shelf registration statement covering the resale of the Notes and use its commercially reasonable efforts to cause such registration statement to be declared effective. If the Company fails to satisfy its registration obligations by certain dates specified in the Registration Rights Agreement, it will be required to pay additional interest to the holders of the Notes.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Registration Rights Agreement, filed as Exhibit 4.4 hereto and incorporated by reference herein.
