April 2018 TETRA Technologies, Inc. Reclassification of Prior Periods Financial Information for Segment Reporting and Discontinued Operations Exhibit. 99.1

RECLASSIFICATION OF PRIOR PERIODS FINANCIAL INFORMATION - EXPLANATORY NOTE As previously disclosed, on February 28, 2018, TETRA Technologies, Inc. (“TETRA”) completed its acquisition (the “Acquisition”) of Swiftwater Energy Services, LLC (“Swiftwater”). Swiftwater is engaged in the business of providing water management and water solutions to oil and gas operators in the Permian Basin market. As also previously disclosed, on March 1, 2018, TETRA completed its divestiture (the “Divestiture”) of its offshore heavy lift, plugging and abandonment, decommissioning, cutting, diving and related consulting businesses and the operations of Maritech Resources, LLC (“Maritech”), including Maritech’s offshore oil and gas leases.   As a result of the Acquisition and the Divestiture, TETRA has reorganized its financial reporting segments and intends to manage its operations through three operating divisions: (i) Completion Fluids & Products, (ii) Water & Flowback Services, and (ii) Compression. TETRA previously had five financial reporting segments organized into four operating divisions: (i) Fluids, (ii) Production Testing, (iii) Compression, and (iv) Offshore. The Completion Fluids & Products operation was previously reported as part of the Fluids Division. The Fluids Division also included TETRA’s water management services operations (as they existed prior to the Acquisition). The Water & Flowback Services Division will include the expanded water management services operations and TETRA’s production testing operations. The operations of the former Offshore Division, which consisted of the previous Offshore Services segment and the Maritech segment, will be reported as discontinued operations.   TETRA will utilize the new financial segment presentation in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 and in TETRA’s related earnings release.   In an effort to assist investors in their understanding of the new financial segment presentation and to facilitate the ability to more effectively evaluate and compare prior operating results with future operating results, TETRA is furnishing the following summary of unaudited historical financial information reclassified under the new financial segment presentation as well as on a consolidated basis.   The following pages present unaudited historical financial information for the quarterly and annual periods in the three year period ended December 31, 2017 reclassified to conform to the new segment presentation, and excluding our discontinued operations. Reconciliations of all non-GAAP financial measurements to their nearest GAAP measurement are presented in the attached appendix.

Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, Adjusted EBITDA, Adjusted EBITDA as a percent of revenue, Adjusted income (loss) before taxes, Adjusted income (loss) before taxes as a percent of revenue, adjusted free cash flow. 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; and determine the ability to incur and service debt and fund capital expenditures. Adjusted EBITDA is defined as earnings before interest, taxes, depreciation, amortization, impairments and special items, equity compensation, and allocated corporate TETRA’s overhead charges to our CSI Compressco LP subsidiary, pursuant to our Omnibus Agreement, which were reimbursed with CSI Compressco LP(CCLP) common units. Adjusted EBITDA as a percent of revenue is defined as Adjusted EBITDA divided by revenue. Adjusted income (loss) before taxes (and adjusted income (loss) before taxes as a percent of revenue) is defined as the Company's (or the segment's) income (loss) before taxes, excluding certain special or other charges (or credits). Adjusted income (loss) before taxes as a percent of revenue is defined as Adjusted income (loss) before taxes divided by revenue. Adjusted free cash flow is a non-GAAP measure that TETRA defines as Adjusted EBITDA minus capital expenditures. 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, 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.
