[Form 4] Stepan Co. Insider Trading Activity

Rhea-AI Filing Summary

Stepan Co. (SCL) Form 4 filed 08/06/25 details insider activity by Director F. Quinn Stepan Jr. on 08/04-05/25.

• Sales: 6,300 shares at $49.962 and 3,700 shares at $50.489 (≈10,000 total; ≈$500k gross).
• Gift: 3,000 shares transferred to joint tenancy with spouse at no cost (Code G).
• Other: 0.615 shares withheld for taxes (Code F) and 2.281 deferred share units converted to stock (Code G/A).

Post-trade direct ownership drops to 159,423 shares, down roughly 6%, while indirect interests total ≈429 k shares across family LLCs, trusts, ESOPs and estates. The director also holds 63,405 deferred share units plus 43,167 units in his father’s deferred plan.

No Rule 10b5-1 trading plan box was marked, suggesting discretionary transactions. Given the company’s ~22 m share float, the 10 k-share sale is immaterial to liquidity but may be watched as a sentiment signal.

Positive

• None.

Negative

• Director sold ~10,000 shares (~$0.5 M) outside a Rule 10b5-1 plan, trimming direct stake by about 6% and potentially signaling modest insider caution.

Insights

Securities Analyst

TL;DR: Small insider sale (~$0.5 M) lowers direct stake 6%; float impact negligible, sentiment mildly negative.

The Form 4 shows routine portfolio moves rather than a strategic exit. The director still owns ~159 k direct shares and controls sizable indirect stakes, keeping alignment with shareholders. Absence of a 10b5-1 plan opens questions on timing but the 10 k-share volume is only ~0.05 % of outstanding stock, limiting market impact. I view the filing as informational with neutral valuation effect.

Corporate Governance Expert

TL;DR: Insider remains large holder; governance risk unchanged despite ad-hoc selling.

Gifts to spouse and continued substantial indirect holdings indicate ongoing family control. The administrative correction noted for May suggests improved reporting accuracy. No red flags on compliance; signatures and footnotes are complete. Overall governance posture unaffected; filing is standard.
