Robert Dahdah

Robert Dahdah (chief executive) discloses dealings in 2 companies, chiefly Nuance Communications, Inc. and PTC Inc. Over a trading history stretching from 29 April 2021 to 1 December 2025, the count stands at 11 filings.

Every open-market trade on record is a sale: 1 sale worth €3.1M. Outside the open market, there are 7 share grants and 2 option exercises.

Most recently, on 2 December 2025, the filings show an option exercise in PTC Inc. The median gap between a trade and its publication by SEC (Form 4) is 3 days. Section 16 rules allow two business days to file each Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
