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.
OST offering FAQ
When did OST last execute an offering?
Per SEC filings, Ostin Technology Group Co., Ltd.'s most recent priced offering document is a 424B5 filed 2025-06-30. Note a 424B takedown can price shares or notes (debt) — the linked document says which.
When did OST last announce or register an offering?
The most recent registration is a F-1/A filed 2024-08-30. 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.
