Shawn M. Lyon

Shawn M. Lyon discloses dealings in 2 companies, chiefly Marathon Petroleum Corp and MPLX LP. Over a trading history stretching from 18 November 2022 to 31 August 2026, the count stands at 23 filings.

On the open market, the record shows 1 purchase worth €196k and 3 sales worth €1.2M. Taken together, the sales exceed the purchases by €1.0M. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. Besides market trades, the filings include 15 share grants and 2 option exercises. 2026 to date brings no purchases and 3 sales.

On 1 September 2026 came the latest disclosure, an open-market sale for €134k in Marathon Petroleum Corp. The last purchase on record was published on 11 March 2025, which is 586 days ago. Filings reach the SEC (Form 4) feed a median of 4 days after the trade. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
