Garry L. Peiffer (board member) discloses dealings in 2 companies, chiefly MPLX LP and Marathon Petroleum Corp. We count 120 filings; the first trade dates from 30 June 2011 and the latest from 14 August 2026.

Purchases make up the whole of the open-market record (3 purchases, €1.3M). Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 117 share grants.

A typical purchase (the median) is worth €450k. For 3 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 33% of cases, with a median move of -8.2%. These figures describe past trades and do not predict future prices.

The record was last updated on 18 August 2026 with a share grant in MPLX LP. The last purchase on record was published on 13 August 2019, which is 2,644 days ago. The median gap between a trade and its publication by SEC (Form 4) is 3 days. For comparison, the SEC allows two business days to file a Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
