Federal contracts (USAspending, awards started in the last 180 days)

No contract award starting in the last 180 days was found for a recipient named exactly "AUTOMATIC DATA PROCESSING INC". Subsidiaries and differently-spelled recipients are not matched — search contracts.

Lobbying (Senate LDA, as client)

No LDA filing posted since October 2025 names "AUTOMATIC DATA PROCESSING INC" as the client. Filings under a subsidiary or trade-association name are not matched — search lobbying.

Companies whose stock was traded by the same people who traded ADP, by number of filers in common. It shows overlap in public filings and nothing else.

Insiders and their transactions come from SEC EDGAR Form 4 filings for this issuer. Contracts and lobbying are matched by exact normalized name (suffixes like Inc./Corp. ignored) to USAspending recipients and LDA clients — a conservative match that misses subsidiaries on purpose.
