John C. Vollmer: trading record in brief
This profile gathers the share dealings of John C. Vollmer across 2 companies, led by Aecom and Amentum Holdings, Inc. In total, 19 filings cover trades dated from 15 December 2017 to 6 February 2026.

The newest entry dates from 10 February 2026: a share grant, in Amentum Holdings, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 3 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
