William M. Lambert: trading record in brief
William M. Lambert (senior executive) discloses dealings in 2 companies, chiefly MSA Safety Inc and Kennametal Inc. The record holds 28 filings, for trades running from 24 May 2021 to 14 September 2026.
On the open market, the record shows 1 purchase worth €906k and 1 sale worth €1.3M. Netting one side against the other leaves €400k of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 6 share grants and 10 option exercises.
The newest entry dates from 16 September 2026: a transaction, in MSA Safety Inc. The last purchase on record was published on 5 May 2022, which is 1,627 days ago. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
