CNI 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.

CNI offering FAQ

When did CNI last execute an offering?

No executed-offering document (424B pricing supplement or 8-K item 3.02) appears in the 1001 filings EDGAR returns for CANADIAN NATIONAL RAILWAY CO, reviewed back to 2000-04-26.

When did CNI last announce or register an offering?

No offering registration (S-1/S-3/F-1/F-3) appears in the filings reviewed back to 2000-04-26.

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.
