[Form 4] AdvanSix Inc. Insider Trading Activity

Rhea-AI Filing Summary

AdvanSix Inc. (ASIX) – Form 4 insider filing

Director Patrick Williams reported the award of 5,020 restricted stock units (RSUs) on 18 June 2025 under the company’s 2016 Stock Incentive Plan. The RSUs were granted at $0 cost and will vest in full on 18 June 2026. Following the grant, Williams’ direct beneficial ownership rose to 33,641 common shares, which includes 76 dividend-equivalent shares credited on unvested awards. No open-market purchases, sales, or derivative security transactions were reported in the filing.

The disclosure reflects routine director equity compensation intended to align incentives with shareholders and does not represent a material change to the company’s capital structure or insider buying/selling trends.

Insights

Corporate Governance Expert

Routine RSU grant; immaterial to valuation

The Form 4 shows a standard annual equity award to a non-employee director. Granting 5,020 RSUs (≈0.02% of shares outstanding) modestly increases insider alignment but has no direct cash impact and does not signal management’s view on valuation. Because the award vests in a single year, dilution risk is minimal and already contemplated in the company’s equity plan. Overall, the event is administrative rather than market-moving.

Portfolio Manager

No buy/sell signal; neutral for investors

With no shares sold and only compensation-related RSUs granted, the filing provides limited insight into insider sentiment. Williams now holds 33,641 shares, a modest stake that keeps his interests aligned but does not meaningfully shift insider ownership percentages. I view the news as non-impactful for trading or valuation models.
