SUPPLEMENT TO PROXY STATEMENT

FOR THE ANNUAL MEETING OF STOCKHOLDERS

To Be Held on August 21, 2024

EXPLANATORY NOTE

The purpose of this supplement (this “Supplement”) to the definitive Proxy Statement of Enservco Corporation (the “Company”), filed with the Securities and Exchange Commission on July 10, 2024 (the “Proxy Statement”), relating to the Company’s Annual Meeting of Stockholders to be held on August 21, 2024, is to amend and replace the proxy card included in the Proxy Statement. After filing the Proxy Statement, the Company discovered that, due to a clerical error, an incorrect version of the proxy card was inadvertently filed with the Proxy Statement. A copy of the new proxy card is attached to this Supplement.

The proxy card or voting instruction form initially distributed with the Proxy Statement is no longer valid. If you have already returned the original proxy card or provided voting instructions, your proxy card or voting instruction will not be valid and will not be voted as directed. You must sign the new proxy card or submit new voting instructions.

Your vote is important. Please use the new proxy card distributed with this Supplement to vote your shares.

There are no changes to the proposals to be acted upon at the Annual Meeting, which are described in the Proxy Statement. Except as amended or supplemented by the information contained in this Supplement, all information set forth in the Proxy Statement continues to apply and should be considered in voting your shares. This Supplement should be read in conjunction with the Proxy Statement.

The date of this Supplement to Proxy Statement is July 19, 2024.
