[SCHEDULE 13G] CEA Industries Inc. SEC Filing

Rhea-AI Filing Summary

Comerica Inc. (CMA) filed a Form 4 showing that director Ximena G. Humrichouse received 1,875 restricted stock units (RSUs) on 07/29/2025 under the company’s Long-Term Incentive Plan. The award is coded “A” (acquisition) at $0 cost, indicating a non-cash equity grant rather than an open-market purchase. The RSUs vest 100% on the grant date and will generally convert into an equal number of common shares one year after the director leaves the Board.

After the grant, Humrichouse’s direct beneficial ownership increased to 47,688 CMA shares. No derivative securities were reported, and there were no sales or option exercises disclosed. The transaction reflects routine director compensation and has minimal impact on Comerica’s share count or near-term financial outlook.

Insights

Equity Compensation Analyst

TL;DR: Routine RSU grant; immaterial share count; neutral investor impact.

The filing documents a standard equity award of 1,875 RSUs to director Ximena G. Humrichouse, boosting her holdings to 47,688 shares. At roughly 0.03% of Comerica’s 132 million shares outstanding, dilution is negligible. The RSUs settle post-service, aligning director incentives with long-term performance. No cash changed hands and no derivatives were created or exercised. Given the modest size and absence of market transactions, I view the disclosure as not impactful for valuation or trading decisions.
