OPTX offering-related filings from SEC EDGAR, newest first (capped at 40). Each links to the original document.

Two honest limits. (1) A 424B takedown can price shares or notes — EDGAR’s metadata doesn’t say which, so open the document: large investment-grade filers use these mostly for bond deals (no dilution), small-caps mostly for shares. (2) At-the-market (ATM) programs sell shares gradually and individual sales are not separately filed — the visible footprint is the enabling shelf and its 424B5; actual ATM share counts surface later in the 10-Q/10-K share count. Educational information from public filings, not investment advice.

OPTX offering FAQ

When did OPTX last execute an offering?

Per SEC filings, SYNTEC OPTICS HOLDINGS, INC.'s most recent priced offering document is a 424B4 filed 2026-04-30. Note a 424B takedown can price shares or notes (debt) — the linked document says which.

When did OPTX last announce or register an offering?

The most recent registration is a S-1 filed 2026-07-23. A registration is capacity to sell shares — not a sale.

Does an offering always mean dilution?

Registered direct offerings and shelf takedowns issue new shares and dilute existing holders. Resale registrations (424B3/B7) let existing holders sell and do not create new shares. Secondary sales by insiders also do not dilute. Each row here is labeled with what it is.
