Form 144 is filed by affiliates when they intend to sell restricted or control securities under Rule 144. Each event is a notice of intent; we never claim a sale happened until a matching Form 4 row appears.
Form 4 is the after-the-fact report of an insider transaction: it tells you what happened, on what date, at what price, in what code. Form 144 is the before-the-fact notice of an intended sale of restricted or control securities under Rule 144: it tells you what an affiliate plans to sell, approximately when, and at what aggregate value. A 144 filing is intent, not outcome; a Form 4 is outcome. Both are public records.
The SEC requires affiliates to file Form 144 before selling restricted or control securities to inform the market that a sale is imminent. Form 4 follows when the transaction actually settles. We track both so you can see the planned sale, the realised sale, and any gap between them. The approximate sale date on each row is the date the affiliate gave as the intended sale window; the actual transaction will show up on the company's insider-transactions page at /stocks/<ticker>/insider-transactions.
Form 144 is the SEC's notice of proposed sale. An affiliate of an issuer (typically an officer, director, or 10% beneficial owner) files Form 144 when they intend to sell restricted or control securities under Rule 144. The filing announces intent to sell; it is not a confirmation that a sale happened.
Form 144 is filed before the sale, as a notice of intent. Form 4 is filed after the transaction, as the report of what actually happened. A 144 without a matching Form 4 means the affiliate gave notice but did not execute the sale in the reported window; a Form 4 without a prior 144 (for restricted/control securities) means the affiliate sold without filing the required notice.
Form 144 is the only public filing that pre-announces insider sales before they happen. Tracking 144 filings lets you see planned dispositions — the issuers and sellers are identified, the approximate sale date is given, and the units and aggregate market value are reported. The signal matters because it precedes the actual sale; treat it as intent, not outcome.
Form 144 requires the seller to report the aggregate market value of the securities to be sold, based on the closing price as of a date within a defined window before the filing. The reported value is what the seller expects to receive in aggregate; the actual realised value may differ if the market moves between the notice and the sale.
Generally yes. Form 144 is filed by affiliates — the same population as Form 4 reporters — but with a specific subset of rules (Rule 144 governs how restricted/control securities can be sold). The seller relationship field on this page is the affiliate's role at the issuer: officer, director, 10% owner, or other.
