David Russell Gaugh: trading record in brief
This profile gathers the share dealings of David Russell Gaugh in Amphastar Pharmaceuticals, Inc. The record holds 2 filings, for trades running from 18 July 2025 to 1 June 2026.
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.
On 3 June 2026 came the latest disclosure, a share grant in Amphastar Pharmaceuticals, Inc. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
