"Disclosed insider exposure" sums this person's most-recently-reported share counts across each company they're an insider in, multiplied by the current underlying price. It is not net worth — it misses retail holdings, private investments, real estate, index funds, and any company where the person isn't an SEC-reporting insider. For informational purposes only.

Holdings By Holder

Who holds the shares on record: the insider directly, and each trust, LLC, partnership or family member reported as an indirect holder on the latest Form 4 that lists them. Holder names come from the filing's footnotes. Rows under No longer reported appeared on earlier filings but not the latest one, usually because the holder was emptied or folded into another; they are not counted in the total.

Recent Filings

178 filings

Insider activity across all companies, newest first. Form 4 rows are post-trade confirmations (buys, sells, grants, exercises). Notice (144) rows are pre-trade notices of intent to sell restricted or control stock under Rule 144, so not all of them end in a sale. Under each notice: the role the filer ticked on it, and whether a sale followed (a Form 4 sale within 30 days, or a sale listed on a later notice).

Form 4 codes: P = open-market purchase · S = open-market sale · A = grant/award · M = option exercise · F = tax withholding at vest · G = bona-fide gift · D = disposition to issuer · J = other (see filing footnote). Only P / S codes carry directional signal.
Notice (144 / 144/A): Form 144 is a notice of intent to sell restricted/control stock under Rule 144, filed before the sale; 144/A is an amendment, and an amended or cancelled notice is not listed. Many notices are pre-scheduled under Rule 10b5-1 plans. A Form 4 with code S typically follows within a few days when the planned sale executes. Someone who is no longer an officer or director (or never was) files no Form 4, so for them a sale shows up only on a later notice, which lists the seller's sales from the 3 months before it. "No sale on file" means neither record shows one; a dash in Net $ means the value filed on the notice doesn't fit the stock's price (likely a typo).

Sales Reported Only on Form 144

1 sale · $1.55M

Each Form 144 lists the seller's sales of the company's stock in the 3 months before it. These are the sales on this filer's notices that no Form 4 on file shows, which is the usual case once someone is no longer an officer or director, or for an affiliate who never files Form 4s. Each sale is listed once, with the first notice that reported it.
