Every S-3 that Milestone Scientific, Inc. (MLSS) has filed with the SEC in the last 12 months is listed below, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
A S-3 covers the shelf registration that lets an established company sell over time, so if you follow MLSS and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full MLSS filings page.
Milestone Scientific Inc. (MLSS) filed Pre-Effective Amendment No. 1 to its shelf registration statement on Form S-3 (File No. 333-298804). The amendment’s sole purpose is to correct a clerical error where the company’s signature block was inadvertently omitted from the original filing.
The amendment also adds an updated Exhibit 5.1, an opinion of Tarter Krinsky & Drogin LLP that now bears a conformed signature and includes the related consent. Other than these technical changes to the cover page, exhibit index, signatures, and Exhibit 5.1, the prospectus and remaining disclosure remain unchanged.
