C. Keith Hartley

All filings by C. Keith Hartley on record concern Universal Display CORP \pa\, in the capacity of board member. The record holds 24 filings, for trades running from 31 December 2015 to 30 September 2026.

No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The record was last updated on 2 October 2026 with a share grant in Universal Display CORP \pa\. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 4 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
