Item 3.02. Unregistered Sales of Equity Securities.

As of November 1, 2025, North Haven Private Income Fund LLC ("we", the "Company" or the "Fund"), sold approximately 990,164 of the Company’s Class S units (the “Units”) for an aggregate offering price of approximately $18.50 million, reflecting a purchase price of $18.68 per unit (with the final number of Units being determined on November 20, 2025).

The sale of Units was made pursuant to subscription agreements entered into by the Company and its unitholders. The issuance of the Units is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereof and Regulation D thereunder. The Company relied, in part, upon representations from the unitholders in the subscription agreements that each unitholder was an accredited investor as defined in Regulation D under the Securities Act.

On November 26, 2025, the Company disclosed the below information.
