DNTH 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.

DNTH offering FAQ

When did DNTH last execute an offering?

Per SEC filings, Dianthus Therapeutics, Inc. /DE/'s most recent priced offering document is a 424B5 filed 2026-03-11. Note a 424B takedown can price shares or notes (debt) — the linked document says which.

When did DNTH last announce or register an offering?

The most recent registration is a S-3MEF filed 2026-03-10. 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.
