Explanation of Responses:

Id	Content
F1	The reporting person and his spouse entered into a transmutation agreement (the "Transmutation Agreement") pursuant to which the reporting person and his spouse agreed that (i) 96,833 shares of Cactus. Inc. Class A common stock owned by the reporting person and his spouse as community property would be deemed to be the separate property of the reporting person's spouse (the "Spouse GRAT Shares") and (ii) 96,833 shares of Cactus, Inc. Class A common stock owned by the reporting person and his spouse as community property would be deemed to be the separate property of the reporting person (the "Reporting Person GRAT Shares"). The number of shares reported as directly beneficially owned by the reporting person has been reduced by the same amount.
F2	Concurrently with the entry into the Transmutation Agreement, the reporting person's spouse contributed the Spouse GRAT Shares to a grantor retained annuity trust of which the reporting person is the trustee and the reporting person's spouse is the annuitant. Accordingly, such shares are now reported as indirectly beneficially owned by the reporting person through such grantor retained annuity trust. The reporting person disclaims beneficial ownership of these shares except to the extent of his pecuniary interest therein, if any.
