Kathleen M. Mazzarella: trading record in brief
Kathleen M. Mazzarella is a declared insider at 5 companies (chief executive); the most frequent names are Waste Management Inc, Graybar Electric Co Inc and Cigna Corp. Between 8 January 2016 and 23 June 2026, the trades on record add up to 31 filings.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Compensation-driven entries like these are tracked, but they say little about how insiders judge the share price.
The record was last updated on 24 June 2026 with a share grant in Core & Main, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
