#### PART III — NARRATIVE

#### <br>
State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be ﬁled within the prescribed time period.

Tortoise Midstream Energy Fund, Inc. (the "Registrant") is unable to complete and file its Form N-CSR relating to the fiscal year ended November 30, 2022 within the time period prescribed without unreasonable effort or expense. Registrant had previously announced its anticipated conversion from a C-Corp to a regulated investment company (RIC) for federal income tax purposes for the fiscal year ending November 30, 2022, and took certain tax positions in connection with the conversion. Registrant has re-evaluated certain of those tax postions and is restating its financial statements for the period ended November 30, 2021 as a result, which has caused a delay in finalizing Registrant's current year financial statements. Registrant will also restate its May 31, 2022 semi-annual financial statements.

Registrant currently expects to file its Form N-CSR on or before the 15<sup>th</sup> calendar day following its prescribed due date.

|  | If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. |
