Louis l. Testoni: trading record in brief
Louis l. Testoni (board member) discloses dealings in Koppers Holdings Inc. to SEC (Form 4). Over a trading history stretching from 6 May 2021 to 2 May 2025, the count stands at 5 filings.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The record was last updated on 6 May 2025 with an option exercise in Koppers Holdings Inc. The median gap between a trade and its publication by SEC (Form 4) is 4 days. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
