[Form 4] H.B. Fuller Company Insider Trading Activity

Rhea-AI Filing Summary

H.B. Fuller (FUL) Form 4: Exec VP Business Transformation Nathan D. Weaver reported a modest insider sale on 08/05/2025. He disposed of 213.1901 common shares held in the company 401(k) plan at $56.84 each, shares that had been accumulated via dividend reinvestment from 04/28/2025-07/24/2025. Post-sale, the plan holds zero shares while Weaver retains 6,970 directly owned shares.

The filing also outlines substantial long-term equity exposure:

• 94,841 employee stock options (strike $26.66-$77.72, expirations 2026-2035); options granted before 2024 are fully vested, later grants vest 33%/33%/34%.
• 5,848 phantom units convertible 1-for-1 into common stock upon separation or an elected date.
• 4,298 restricted stock units vesting between 2026-2028.

No other transactions, purchases, or material corporate events were disclosed in this filing.

Insights

Securities Analyst

TL;DR: Minor insider sale; executive still holds sizable equity via options & RSUs—overall neutral signal for investors.

The 213-share sale represents a negligible fraction of both daily volume and the insider’s total economic exposure. Weaver continues to control 6,970 direct shares plus roughly 94.8k options, 5.8k phantom units and 4.3k RSUs, indicating continued alignment with shareholder value creation. Because the divestiture arose from a retirement-plan accumulation cycle and is not paired with broader insider selling, I view the filing as routine and not materially impactful to FUL’s investment thesis.
