DALLAS, Dec. 19, 2025 /PRNewswire/ -- The NXG Cushing® Midstream Energy Fund (NYSE:SRV) (the "Fund") declared a special distribution of $2.14 per common share. This special distribution will be payable to common shareholders pursuant to the table below:

Record Date	Ex-Dividend Date	Payment Date	Distribution Amount
December 29, 2025	December 29, 2025	December 31, 2025	$2.14

This special distribution is in addition to the Fund's previously announced December distribution of $0.45 per share. This special distribution is being paid to allow the Fund to meet its 2025 distribution requirements as a regulated investment company for U.S. federal income tax purposes.

It is estimated that 100% of the special distribution will consist of long-term capital gain. The sources the distribution are only estimates and are provided to you pursuant to regulatory requirements and are not being provided for tax reporting purposes. The final determination of such sources will be made and reported to shareholders in early 2026 for the 2025 dividends, after the end of the calendar year when the Fund determines its earnings and profits for the year. The final tax status of a distribution may differ substantially from this information.

The distribution shall be paid on the payment date unless the payment of such distribution is deferred by the Fund's Board of Trustees upon a determination that such deferral is required in order to comply with applicable law or to ensure that the Fund remains solvent and able to pay its debts as they become due and continue as a going concern.

ADDITIONAL INFORMATION ABOUT THE FUND

The Fund is a non-diversified, closed-end management investment company with an investment objective of seeking a high after-tax total return from a combination of capital appreciation and current income. The Fund seeks to achieve its investment objective by investing, under normal market conditions, at least 80% of its net assets, plus any borrowings for investment purposes, in a portfolio of midstream energy investments. The Fund considers midstream energy investments to be investments that offer economic exposure to securities of midstream energy companies, which are companies that engage provide midstream services in the energy infrastructure sector, including the gathering, transporting, processing, fractionation, storing, refining and distribution of natural resources, such as natural gas, natural gas liquids, crude oil refined petroleum products, biofuels, carbon sequestration, solar, and wind. The Fund considers a company to be a midstream energy company if at least 50% of its assets, income, sales or profits are committed to, derived from or otherwise related to midstream energy services. The Fund's shares are traded on the New York Stock Exchange under the symbol "SRV."

There can be no assurance that the Fund will achieve its investment objectives. Investments in the Fund involve operating expenses and fees. The net asset value of the Fund will fluctuate with the value of the underlying securities. It is important to note that closed-end funds trade on their market value, not net asset value, and closed-end funds often trade at a discount to their net asset value.
