Item 3.02 Unregistered Sales of Equity Securities.

On May 1, 2026, Macquarie Infrastructure Fund, L.P. (the “Fund”) sold unregistered limited partnership units (the “Units”) for aggregate consideration of approximately $89,550,000. The following table details the Units sold by the Fund:

	Number of Units Sold⁽¹⁾		Consideration
Class I		1,807.20	$	50,000
Class E		3,134,752.32	$	89,500,000

(1)	The number of Units sold by the Fund was finalized on June 1, 2026, following the calculation of the Fund’s transactional net asset value (“Transactional NAV”) as of April 30, 2026. See Item 7.01 below for more information on the Fund’s Transactional NAV.

The offer and sale of the Units were made as part of the Fund’s continuous private offering to investors that are both (a) accredited investors (as defined in Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)) and (b) qualified purchasers (as defined in the Investment Company Act of 1940, as amended, and the rules thereunder) and were exempt from the registration provisions of the Securities Act, pursuant to Section 4(a)(2) and Regulation D thereunder. Units were sold to third-party investors.

The Fund invests alongside other Macquarie-managed vehicles with substantially similar investment objectives and strategies that, together with the Fund, collectively form the “MIF Program.” On May 1, 2026, the MIF Program (inclusive of the Fund) issued interests for aggregate consideration of approximately $136.9 million⁽²⁾. From October 31, 2025 through May 1, 2026, the MIF Program (inclusive of the Fund) has sold interests for aggregate cash consideration of approximately $591.1 million⁽²⁾ as part of its continuous private offering.

Item 7.01 Regulation FD Disclosure.

Transactional Net Asset Value

The ~~transactional net asset value (the “~~Transactional NAV”) per Unit for each outstanding class of the Fund as of ~~February~~April 2830, 2026 is as follows:

	Transactional NAV as of February 28, 2026
	Transactional NAV as of April 30, 2026
Class I	$	2527.8067
Class E	$	2628.3755

The Fund calculates Transactional NAV for purposes of establishing the price at which transactions in the Fund’s Units are made. A description of the Fund’s valuation process was included under “Item 9. Market Price of and Dividends on the Registrant’s Common Equity and Related Unitholder Matters” of the Fund’s Registration Statement on Form 10 filed on September 24, 2025. Transactional NAV is based on the month-end values of the Fund’s investments, the addition of the value of any other assets (such as cash on hand), and the deduction of the Fund’s liabilities, including certain fees and expenses, in accordance with the Fund’s valuation policy.

⁽²⁾	Other Macquarie vehicles conduct their offerings in currencies other than the U.S. dollar; as such, this figure is approximate and based on exchange rates as of the last business day of the preceding month
