EXPLANATORY NOTE

Artesian Resources Corporation (the "Company") is filing this Amendment No. 1 (“Amendment”) to its Annual Report on Form 10-K for the year ended December 31, 2025 (the "Original 10-K"), which was filed with the Securities and Exchange Commission (the "SEC") on March 16, 2026, solely to correct an error on the cover page regarding the Company's filer status.

Specifically, the Company erroneously checked the box indicating it is an Accelerated Filer. The purpose of this Amendment is to check the box indicating the Company is a Non-Accelerated Filer. This Amendment contains only the cover page, this explanatory note, the exhibit index, the signature page and the new certifications (as further explained in the last paragraph of this explanatory note).

Except for the foregoing, no other changes have been made to the Original 10-K, and this Amendment does not amend, update, or modify any other part of the Original 10-K, including the financial statements or disclosures therein. The Original Filing continues to speak as of the date of the Original Filing, and the Company has not updated the disclosures contained therein to reflect any events that have occurred as of a date subsequent to the date of the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original 10-K.

In accordance with SEC rules, new certifications by the Company’s principal executive officer and principal financial officer are filed herewith as exhibits 31.1 and 31.2 to this Amendment. As no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraph 3 of the certifications has been omitted. The Company is not including certifications pursuant to Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) as no financial statements are being filed with this Amendment.
