Willdan Group Insider Micah Chen Files Form 4; No Transactions Disclosed

TL;DR

**Insider Micah Chen filed a Form 4 for Willdan Group, but it's just a reporting update, no trades.**

AI Summary

This Form 4 filing, dated March 23, 2026, indicates that Micah Chen, an insider at Willdan Group, Inc. (WLDN), has filed a statement of changes in beneficial ownership of securities. While the filing confirms Chen's reporting status and the company's details, it does not disclose any specific transactions (buys or sells) of Willdan Group shares.
