[Form 4] AdvanSix Inc. Insider Trading Activity

Rhea-AI Filing Summary

Form 4 overview

On 18 June 2025, AdvanSix Inc. (ASIX) reported that director Sharon S. Spurlin received 5,020 restricted stock units (RSUs) under the company’s 2016 Stock Incentive Plan. Coded “A” for acquisition, the award was issued at no cash cost and is scheduled to vest in full on 18 June 2026.

After the grant, Spurlin’s direct beneficial ownership rose to 74,746 common shares. The total includes 242 dividend-equivalent shares credited on prior unvested RSUs and deferred stock units, which were exempt from reporting under Rule 16a-11.

No derivative securities, open-market purchases, or sales were reported, making this a routine equity-compensation transaction rather than a signal of trading intent.

Insights

Securities Analyst

TL;DR: Routine RSU grant to director; minimal change in ownership, unlikely to move ASIX share price.

The filing documents a standard equity-compensation grant to an outside director. The 5,020 RSUs represent a modest addition relative to AdvanSix’s 27 million basic shares outstanding and lift Spurlin’s holdings to roughly 0.28 % of total shares. Because the grant is both non-cash and subject to a one-year vest, it does not reflect immediate insider buying conviction. From a valuation or liquidity standpoint, the event is immaterial and should be viewed as part of regular board compensation rather than an indicator of future performance.

Corporate Governance Specialist

TL;DR: Filing confirms adherence to equity-comp plan; signals good disclosure practice, but governance impact is neutral.

AdvanSix continues to compensate directors primarily through time-based RSUs, aligning board incentives with long-term shareholder value. The single-year cliff vest is common for outside directors and fosters retention without excessive dilution. No 10b5-1 plan usage or complex derivatives were involved, indicating straightforward governance. While transparent, the event does not materially alter the company’s ownership structure or board independence profile.
