As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between compensation actually paid to our Named Executive Officers (NEOs) and certain financial performance metrics of the Company using a methodology that has been prescribed by the SEC.

										Value of Initial Fixed $100 Investment Based on:
Fiscal Year		Summary Compensation Table Total for PEO(1)		Compensation Actually Paid to PEO(1)(2)		Average Summary Compensation Table Total for non-PEO NEOs(1)		Average Compensation Actually Paid to non-PEO NEOs(1) (2)		Total Shareholder Return		Peer Group Total Shareholder Return(3)T		Net Income ($ millions)		Adjusted Operating Income ($ millions) (4)

(1) Ms. Evanko served as principal executive officer (PEO) for the full year of each 2022, 2021 and 2020. Our non-PEO named executive officers (NEOs) included: (a) for 2022, Mr. Brinkman, Mr. Hotchkiss, Mr. Vinci, Mr. Ducote and Mr. Belling; (b) for 2021, Mr. Brinkman, Mr. Hotchkiss, Mr. Vinci, Mr. Ducote, Mr. Belling and Scott Merkle (our former CFO); and (c) for 2020, Mr. Hotchkiss, Mr. Vinci and John Bishop (our former COO).

(2) The following amounts were deducted from/added to Summary Compensation Table total compensation in accordance with the SEC-mandated adjustments to calculate Compensation Actually Paid (“CAP”) to our principal executive officer (PEO) and average CAP to our non-PEO named executive officers. The fair value of equity awards was determined using methodologies and assumptions developed in a manner substantively consistent with those used to determine the grant date fair value of such awards.
