STICE J MICHAEL 4

What Happened

• J. Michael Stice, a director of MPLX GP LLC (the general partner of MPLX LP), was granted 1,098.213 units/shares on 2026-05-15 as an award (transaction code A). The reported acquisition price is $0.00, so the filing shows $0 in cash paid for the award. This is a compensation grant, not an open-market purchase or a sale.

Key Details

• Transaction date: 2026-05-15; Filing date: 2026-05-19 (Form 4 accession 0001193125-26-230788).
• Transaction type/code: A = Award/Grant.
• Shares/units acquired: 1,098.213 at $0.00 (total reported cash outlay $0).
• Shares owned after transaction: Not specified in the filing.
• Footnotes/notes: Reporting person is a director of MPLX GP LLC; no 10b5-1, tax-withholding, or other special footnotes disclosed.
• Timeliness: Filing was submitted 4 days after the transaction date; given SEC Form 4 rules this appears to be filed on the due date and is not flagged as late.

Context

• Awards (code A) are typically equity compensation (restricted units or similar) and reflect company pay practices rather than an independent purchase decision—these do not necessarily indicate an insider buying or selling based on a view of the stock.
• Because this was a grant at $0, there was no cash transaction; it is not an exercise or sale.
