Willdan Group, Inc.: what insiders have been doing
This page follows insider dealings at Willdan Group, Inc. as filed with SEC (Form 4), a company from the Energy sector based in Anaheim, United States. The group dates from 1964. The last twelve months, up to 18 October 2026, brought 44 filings signed by 7 insiders.
No insider bought on the market over the period, while 3 insiders filed 9 sales totalling €9.9M. One trade stands out by size: a sale of €4.5M from Brisbin Thomas Donald, disclosed on 4 September 2026, or 0.42% of market capitalisation.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
For context, the typical company on the same exchange (median of 5,814 companies) published 19 filings over the same period, against 44 filings here. Looking back to 2016, when coverage begins, insiders filed 3 purchases and 81 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 2 January 2026 lists revenue at 681.6 m USD and net income at 52.6 m USD.
