Leonard Green & Partners, L.P. 4

What Happened

• Green Equity Investors VI, L.P. (a reported 10% owner of Mister Car Wash, ticker MCW) reported multiple dispositions on 2026-05-19 involving company common stock. The filing shows dispositions of 134,812,845; 80,348,253; 315,683; and 3,736,298 shares, each at $7.00 per share, with line values of $943,689,915; $562,437,771; $2,209,781; and $26,154,086 respectively — totaling approximately $1,534,491,553. These transactions are reported as "Other acquisition or disposition (J)."
• These were disposals in connection with a merger and related contribution agreements (see footnotes): shares were contributed to MCW Parent and, at the effective time of the Merger, were automatically cancelled and extinguished pursuant to the Merger Agreement and Contribution Agreement. These are not open-market sales by an individual insider.

Key Details

• Transaction date: 2026-05-19; Price: $7.00 per share for each reported disposition.
• Per-line share counts and values: 134,812,845 @ $7 = $943,689,915; 80,348,253 @ $7 = $562,437,771; 315,683 @ $7 = $2,209,781; 3,736,298 @ $7 = $26,154,086. Total ≈ $1.534B.
• Purpose/footnotes: Transactions relate to the Agreement and Plan of Merger (Feb 17, 2026) and a Contribution Agreement — shares were contributed to Parent and cancelled (see F1, F2, F3, F8, F10–F13).
• Ownership after transaction: the common shares reported were cancelled at the merger effective time; remaining beneficial interests, if any, are reflected in equity interests in the Parent rather than MCW common stock.
• Reporting status: filing covers the reported date (2026-05-19); no indication in this filing of a late Form 4.

Context

• This filing reflects an institutional disposition tied to a corporate merger/recapitalization, not a personal open-market sale by an executive. For retail investors, that distinction matters: these disposals were part of a transaction structure (shares contributed and cancelled), not necessarily a signal of manager sentiment about the company’s future.
• Remarks note related LGP entities and partners who serve on MCW’s board; those affiliations explain why multiple affiliated entities are reported and why some parties disclaim direct beneficial ownership of the cancelled shares.
