Insights

Securities Compliance Analyst

TL;DR Routine insider notice of proposed sale; quantities are small relative to outstanding shares and reflect option exercise.

This Form 144 documents a planned sale of 1,987 ADP shares tied to an option granted in 2021, with cash payment and execution via Fidelity on NASDAQ. The filing includes a recent prior sale of 1,381 shares on 06/13/2025. From a compliance perspective, the notice meets Rule 144 disclosure elements: acquisition details, source (issuer/options), broker, approximate sale date, and prior sales during the three-month lookback. No material operational or financial disclosures are included.

Equity Research Associate

TL;DR Insider sale disclosed but size is immaterial versus ADP's share count; unlikely to be market-moving.

The disclosed shares to be sold equal 1,987 with an aggregate market value of $599,358.68 against 405,043,142 shares outstanding, indicating a de minimis dilution or share turnover. The shares stem from an option granted on 09/01/2021, exercised or acquired on 09/02/2025, with proceeds listed as cash. Historical sale data (1,381 shares on 06/13/2025 for $424,063.67) provides context for recent insider liquidity but does not by itself signal material change to company fundamentals.
