Explanation of responses
- F1Represents Class B Units of Enchanted Rock Holdings, LLC sold by the Reporting Person to the Issuer in connection with the closing of the Issuer's initial public offering ("IPO") at a price per Class B Unit of $19.85 (the per-share price paid by the underwriters for shares of the Class A Common Stock in the IPO, less the Reporting Person's share of offering expenses). In connection with such sale, the Issuer automatically cancelled an equivalent number of shares of Class B Common Stock held by the Reporting Person.
- F2The Class B Units are exchangeable, at the holder's option, on a one-for-one basis into shares of Class A Common Stock of the Issuer or cash (at the Issuer's election). Upon exchange of a Class B Unit, the corresponding share of Class B Common Stock will be automatically cancelled.
