EXPLANATORY NOTE

Milestone Scientific Inc. is filing this Amendment No. 1 on Form 8-K/A (Amendment No. 1) (this “Form 8-K Amendment”) to amend the Current Report on Form 8-K filed with the Securities and Exchange Commission on January 20, 2026 (the “Original Form 8-K”) solely to include Exhibit 10.1 and modify the address on the cover page, the title of the authorized signatory and Exhibit number. The Original Form 8-K inadvertently omitted the Exhibit, which was described in (but not filed with) the Original Form 8-K and included an incorrect address and an incorrect title of the authorized signatory. While Exhibit 10.1 includes a January 13, 2026 date, the cover page refers to January 15, 2026 as the parties executed the subject document (and the requisite stockholder approval was obtained) on such date. No other items or disclosures in the Original Form 8-K are being amended with this Form 8-K Amendment.
