Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

On January 23, 2025, the Board of Trustees (the “Board”) of NXG Cushing® Midstream Energy Fund (the “Fund”) accepted the retirement of Ronald P. Trout as a Trustee of the Fund.

On January 23, 2025, the Board appointed John Musgrave, Chief Executive Officer and President of the Fund, as a Trustee of the Fund to fill the vacancy created by the retirement of Mr. Trout. Mr. Musgrave serves as an Interested Trustee of the Fund as a result of his position as an officer of the Fund’s investment adviser. Mr. Musgrave is a Class III Trustee.

John H. Alban was previously deemed to be an Interested Trustee of the Fund as a result of his prior position as an officer of the Fund’s investment adviser. Because Mr. Alban has not had, at any time since the beginning of the last two completed fiscal years of the Funds, a material business or professional relationship with the Fund’s investment adviser and is not otherwise defined as an “Interested Person” (as defined in Section 2(a)(19) of the Investment Company Act of 1940) of the Fund, Mr. Alban now serves as an Independent Trustee of the Fund. On January 23, 2025, Mr. Alban was appointed by the Board as a member of the Audit Committee of the Fund and the Nominating and Corporate Governance Committee of the Fund.
