[Form 4] Willdan Group, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Micah Chen, Executive VP & General Counsel of Willdan Group, Inc. (WLDN), had restricted stock units vest and completed a tax-withholding share disposition on 08/18/2025. Performance-based restricted stock units granted 08/02/2022 vested for 2,732 shares, issued at no cash price to the reporting person, increasing immediate beneficial ownership before withholding. To satisfy tax withholding, 1,197 shares were withheld at an indicated value of $109.53 per share, reducing the reporting person\'s beneficial ownership from 41,620 to 40,423 shares. The filing also discloses existing unvested restricted stock units totaling 8,354 shares across several scheduled vesting dates and a prior ESPP purchase of 386 shares on 06/30/2025.

Positive

• Performance-based compensation vested, indicating the company certified achievement of the applicable performance conditions for the award
• Substantial insider ownership remains with 40,423 shares beneficially owned after the withholding, aligning executive interests with shareholders
• Transparent disclosure of remaining unvested RSUs and ESPP purchase shows clear reporting of equity incentives

Negative

• Shares withheld for tax withholding (1,197 shares) reduced reported beneficial ownership versus pre-withholding levels
• No cash proceeds from open-market sales disclosed, so liquidity events for the reporting person are limited to administrative withholding

Insights

Securities Analyst

TL;DR: Executive received performance-based RSUs that vested; shares were withheld for taxes, modestly reducing beneficial ownership.

The Form 4 shows routine executive compensation mechanics rather than market-transacting sales. The Compensation Committee certified performance results triggering vesting of 2,732 performance RSUs effective 08/18/2025. Tax withholding of 1,197 shares at an indicated price of $109.53 was effected, which is an administrative disposition rather than an open-market sale. Post-transaction beneficial ownership of 40,423 shares remains sizable and includes multiple tranches of time-based RSUs with scheduled vesting through 2028. For investors, this is an insider ownership update with no direct cash proceeds to the reporting person disclosed.

Corporate Governance Expert

TL;DR: Governance process followed: performance metrics certified and tax withholding executed; disclosure is complete for these events.

The filing documents the issuer\'s internal certification of performance conditions and the administrative mechanics to satisfy withholding obligations. Footnotes enumerate remaining unvested awards and prior ESPP participation, providing transparency on ongoing executive incentives. There is no indication of discretionary share disposition beyond tax withholding. This is a standard disclosure of equity compensation activity under Section 16 reporting rules.
