• Nature: Disposition to issuer (derivative securities) — automatic, pro rata, non-discretionary redemption under MH LPA and Opco LLCA.
• Related effects: Corresponding Opco LLC Interests surrendered and an equal number of Class B common shares held by MH were surrendered and cancelled; an equal number of MH Units held by the reporting person were cancelled.

Context

• This transaction reflects a contractual redemption mechanism (conversion/cash-out of partnership/Opco interests in connection with a public offering), not a discretionary insider sale. It reduces the reporting person’s MH Units and the related Class B/Common unit structure; Class B shares held by MH carried voting but no economic rights per the filing.
• For retail investors: such redemptions are routine consequences of LP/Opco governance and capital-raising events; they do not necessarily signal discretionary buying or selling intent by the insider.
