Appendix

Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, Adjusted EBITDA, Adjusted EBITDA margin, enterprise value, distributable cash flow, adjusted free cash flow, liquidity, distribution coverage ratio and debt to Adjusted EBITDA. Adjusted EBITDA is used as a supplemental financial measure by the management to: evaluate the financial performance of assets without regard to financing methods, capital structure or historical cost basis; measure operating performance and return on capital as compared to competitors; and determine the ability to incur and service debt and fund capital expenditures. assess ability to generate available cash sufficient to make distributions to the CSI Compressco’s unit holders and general partner; Adjusted EBITDA is defined as sum of EBITDA, non-cash equity compensation expense, and amortization of financing costs, less unusual items. Adjusted EBITDA margin is defined as Adjusted EBITDA divided by revenue. Enterprise value is defined as market capitalization plus the sum of long-term and short-term debt on the consolidated balance sheet, less cash, excluding restricted cash on the consolidated balance sheet. Management uses enterprise value as a measure of the market value of the company if it were free of debt. CSI Compressco (CCLP) distributable cash flow is used as a supplemental financial measure by management as it provides important information relating to the relationship between CCLP’s financial operating performance and its cash distribution capability. Additionally, distributable cash flow is used in setting forward expectations. CCLP’s distributable cash flow is defined as EBITDA less current income tax expense, maintenance capital expenditures, and interest expense, plus the non-cash cost of compressors sold and equity compensation expense. The CCLP distribution coverage ratio is defied as the ratio of distributable cash flow to the quarterly distribution payable on all outstanding common and subordinated units and the general partner interest. CCLP Distribution coverage ratio provides important information relating to the relationship between financial operating performance and cash distribution capability. Debt to Adjusted EBITDA is defined as balance of debt at the end of the period divided by last twelve months of Adjusted EBITDA. Liquidity is defined as the availability under the Credit Agreement (consisting of maximum credit commitment, less balance outstanding) plus the sum of unrestricted cash on the consolidated balance sheet. Management views liquidity as a measure of the Company’s ability to fund investing and financing activities. TETRA only adjusted free cash flow is a non-GAAP measure that the Company defines as cash from TETRA's operations, excluding cash settlements of Maritech AROs, less capital expenditures net of sales proceeds, and including cash distributions to TETRA from CSI Compressco LP. These non-GAAP financial measures should not be considered an alternative to net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. These non-GAAP financial measures may not be comparable to EBITDA, distributable cash flow or other similarly titled measures of other entities, as other entities may not calculate these non-GAAP financial measures in the same manner. Management compensates for the limitation of these non-GAAP financial measures as an analytical tool by reviewing the comparable GAAP measures, understanding the differences between the measures and incorporating this knowledge into management's decision making process. Furthermore, these non-GAAP measures should not be viewed as indicative of the actual amount of cash that is available for distributions or planned distribution for a given period, nor should they be equated to available cash as defined in the Partnership's partnership agreement.

Non-GAAP Reconciliations Note: Starting in 2016 Q1, amortization of financing costs has been included in interest expense due to the FASB accounting changes. Numbers are adjusted to reflect this change.
