• Security: Class B Units of Enchanted Rock Holdings, LLC (treated as a derivative security in the filing).
• Ownership after transaction: not disclosed in the filing.
• Footnote F1: Units sold to the issuer at $19.85 (the IPO per-share price less the reporting person’s share of offering expenses); equivalent Class B common shares were cancelled.

Context
This was a disposition to the issuer tied to the company’s IPO (not an open-market sale). The units involved are exchangeable/derivative in nature—holders can convert them into Class A common shares or receive cash—so the transaction reflects an IPO-related restructuring/settlement rather than a typical insider sale signaling a change in sentiment.
