[Form 4] Automatic Data Processing Insider Trading Activity

Rhea-AI Filing Summary

Automatic Data Processing (ADP) – Insider Transaction (Form 4)

On 08/06/2025, ADP’s Chief Financial Officer, Peter J. Hadley, reported the acquisition of 1,926.582 shares of ADP common stock. The transaction is coded “A,” indicating a company-related award rather than an open-market purchase. The stated price is $0.00, implying the shares were received via equity compensation (e.g., restricted-stock vesting or similar plan). Following the grant, Hadley’s direct ownership increased to 8,161.356 shares.

No derivative securities were reported, and no disposals occurred. While the absolute dollar value (≈ $480k at a ~$250 share price) is modest relative to ADP’s market cap, insider ownership growth—especially by a C-suite officer—can signal alignment of management and shareholder interests.

Positive

• CFO’s direct ownership increases to 8,161 shares, marginally strengthening management–shareholder alignment

Negative

• None.

Insights

Financial Analyst

TL;DR: CFO received ~1.9k ADP shares via equity award; ownership now 8.2k—incrementally positive but not market-moving.

The Form 4 shows a routine equity grant to CFO Peter Hadley. Because the shares were awarded at zero cost under a compensation plan, cash commitment is absent, limiting the signaling effect versus an open-market buy. Nevertheless, higher insider ownership modestly aligns incentives with shareholders. The volume represents <0.001% of ADP’s ~410 m shares outstanding, so the transaction is not materially impactful for valuation or float dynamics.
