THE WOODLANDS, Texas, February 27, 2024 / PR Newswire / - TETRA Technologies, Inc. (“TETRA” or the “Company”) (NYSE:TTI) today announced fourth quarter and total year 2023 results.

Brady Murphy, TETRA’s President and Chief Executive Officer, stated, "2023 was a historical year for TETRA with numerous financial records and strategic milestones achieved that will have a significant impact for the Company for years to come. Financial highlights for the year include 2.4 times growth in income from continuing operations, 37% growth in Adjusted EBITDA, 710 basis points improvement in return on net capital employed to 20.5%1, 2.7 times improvement in cash flow from operations and a conversion rate of nearly 40% of Adjusted EBITDA to adjusted free cash flow. Excluding the impact of working capital, our total year 2023 adjusted free cash flow was the highest since 2015 demonstrating progress on generating cash. As of December 2023, our net leverage ratio was 1.13X and liquidity was $126 million. Recent strategic milestones achieved include: the Arkansas Oil and Gas Commission (“AOGC”) unanimously approving the 6,138-acre Evergreen Brine Unit, a combination of TETRA and Saltwerx (a wholly owned subsidiary of ExxonMobil) brine leases for the purpose of future bromine and lithium production, and completing a lithium and bromine resource report for the Evergreen Brine Unit.

Due to the richness of the lithium concentration and the favorable Smackover reservoir properties, the resource report estimated 22 tons per acre of total lithium resources for the Evergreen Brine Unit, which is believed to be the highest to date of any lithium brine resource in the U.S. for which a SK-1300, NI-43-101 or JORC-compliant technical report summary has been published. We also completed the engineering design for our first commercial produced water beneficial re-use project with a planned deployment later this year. And in January 2024, we further strengthened our balance sheet by refinancing, extending, and expanding our term loan, at a more attractive interest rate than our prior term loan. We enter 2024 with a strong and growing base business, a solid balance sheet, over $200 million of liquidity (following the term loan refinancing and inclusive of a $75 million delayed draw feature to fund our bromine project), with a constructive outlook for our products and services. We anticipate further growth in 2024 and expect to continue to generate strong free cash flow from our base business to fund investments in our Arkansas projects. The combination of these plus advances with our produced water beneficial re-use solution, our Arkansas resource position and strategic partnerships provides us the opportunity to continue to drive long-term shareholder value.”

Fourth Quarter Results

Fourth quarter 2023 revenue of $153 million increased 1% from the third quarter of 2023 reflecting the early production facility (“EPF”) sale in Argentina, partially offset by lower than usual onshore year-end activity in the United States and some customer year-end inventory de-stocking for our industrial chemicals business. Net loss before discontinued operations was $4.2 million, inclusive of $8.0 million of non-recurring charges and expenses and compares to net income from continuing operations of $5.5 million in the third quarter of 2023, inclusive of $3.7 million of non-recurring charges and expenses. Net loss per share from continuing operations in the fourth quarter was $0.03 and compares to net income per share of $0.04 in the third quarter of 2023. Adjusted net income per share from continuing operations was $0.03 in the fourth quarter, which compares to $0.07 in the third quarter 2023.

Fourth quarter Adjusted EBITDA of $24.1 million increased 19% year-on-year from $20.3 million in the fourth quarter of 2022 but decreased 7% from $26.1 million in the third quarter of 2023 reflecting a good cash generating EPF sale in Argentina but lower year-end onshore and industrial chemicals activity. Fourth quarter results included unrealized mark-to-market gains on investments of $0.7 million. Excluding these unrealized gains on investments, Adjusted EBITDA for the fourth quarter of 2023 was $23.4 million (15.3% of revenue) and was up 13% year-on-year.

Fourth quarter cash flow from operating activities was $18.9 million and compares to a use of cash of $7.0 million in the fourth quarter of 2022 and to cash flow from operating activities of $14.0 million in the third quarter of 2023. Adjusted free cash flow was $20.1 million in the fourth quarter of 2023 and compares to a use of cash of $14.2 million in the fourth quarter of 2022 and to cash flow of $7.1 million in the third quarter of 2023. Working capital at the end of year was $104 million and compares to $110 million at the end the third quarter of 2023 and to working capital of $101 million at end of 2022. Working capital is defined as current assets, excluding cash and restricted cash, less current liabilities.

Brady Murphy, further stated, "Our Water & Flowback Services business experienced the first slowdown in many quarters, as several customers paused activity over the holidays; we believe in large part because many achieved production targets well ahead of year-end. This combined with some year-end customer destocking activity in our industrial chemicals business resulted in lower activity and lower Adjusted EBITDA compared to the third quarter. However, as we look to the first half of 2024, including our traditional northern Europe seasonal industrial chemicals ramp up in the second quarter, we are seeing a strong recovery in our chemicals business, continued strong activity in our offshore completion fluids business and modest growth in our Water & Flowback Services segment.

Water & Flowback Services revenue for the fourth quarter was $81 million up $2.3 million (3.0%), quarter-over-quarter but declined $1 million (1%) year-on-year. Excluding the EPF sale in Argentina, fourth quarter revenue would have been $75 million. Income before taxes was $2.9 million while Adjusted EBITDA of $11.3 million declined $0.8 million (7%) year-on-year. Excluding the EPF sale, Adjusted EBITDA margins would have been 15% for the fourth quarter, down 400 basis points sequentially due to the lower year-end activity. For the total year, our Water & Flowback Services revenue grew by $33 million (12%) while income before taxes increased by $10 million (64%) and Adjusted EBITDA increased $10 million (23%), yielding an Adjusted EBITDA fall-through of nearly 30% for the year. Total year Water & Flowback Services revenue of $313 million exceeded our total year 2018 revenue with strong Adjusted EBITDA margins, despite 50% lower active frac fleets reflecting our technology and automation initiatives.

“As reported last quarter, we sold one of the three EPFs in Argentina to the operator for an amount of more than $5 million, with all the cash proceeds received in October. We completed an EPF expansion project in January for the same customer and will continue to operate and maintain the EPF for a fixed monthly fee.

“We recently completed the engineering design for our first produced water desalination plant for beneficial re-use applications and are in advanced commercial discussions with one of the largest North America shale producers for their beneficial re-use project which we expect to have awarded shortly. We are also in negotiations with the same customer for a second project, in the Permian Basin, for a commercial demonstration pilot project.

“Completion Fluids & Products also experienced a year-end slowdown driven by industrial chemicals, as several customers went through destocking activities. This also appears to be a seasonal event as activity has rebounded sharply to start the year and we expect the first half of 2024 to be above the second half of 2023. Completion Fluids & Products fourth-quarter 2023 revenue of $73 million decreased $0.7 million (1%), from the third quarter of 2023 but increased $6.3 million (10%) from the fourth quarter of 2022. Income before taxes was $11.0 million in the fourth quarter (15.1% of revenue) compared to $16.9 million (23% of revenue) in the third quarter of 2023. Adjusted EBITDA of $18 million decreased $2.6 million sequentially. Completion Fluids & Products Adjusted EBITDA margins were 25.3% in the fourth quarter compared to 28.6% in the third quarter of 2023 as margins were impacted by lower utilization and lower production volumes. The fourth quarter included $0.6 million in unrealized mark-to-market losses from investments. Excluding unrealized mark-to-market losses from investments, Adjusted EBITDA margins were 26%. For the total year, Completion Fluids & Products revenue grew by $40 million (15%) while income before taxes increased by $21 million (37%) and Adjusted EBITDA increased $22 million (32%), yielding an Adjusted EBITDA fall-through of nearly 55%.

Total year Completion Fluids & Products revenue of $313 million is the highest since 2015 when we completed two large TETRA CS Neptune® projects in the Gulf of Mexico. Total revenue attributed to offshore projects increased 11% year-over-year. We anticipate further growth in 2024 as our pipeline of offshore projects continues to build.

“In January 2024, Eos Energy Enterprises, Inc. ("Eos") announced that it expanded its partnership with TETRA and designated TETRA as its preferred strategic supplier for the full electrolyte products for Eos’ Z3™ long duration energy storage cube. This new agreement expands TETRA’s participation to provide a minimum of 75% of Eos’ total electrolyte demand going forward. Having recently visited Eos’ automated battery assembly line being designed and tested in Milwaukee, we are pleased to see the progress and expect to see a material ramp up in electrolyte deliveries during the second half of 2024.

“During January we updated the previously reported resources report for bromine and lithium in Arkansas. The updated resources report, which now includes measured resources, in addition to indicated and inferred resources, resulted in 3 times more volume of lithium versus what was in the previous report, and slightly higher bromine resources. With TETRA’s current liquidity, including the $75 million delayed draw feature and anticipated 2024 and 2025 free cash flow, TETRA believes it has secured the required capital to advance its bromine processing facility, subject to a final investment decision. TETRA continues to work on completing a Front-End Engineering and Design study (“FEED”) for the lithium processing facility project and a detailed engineering study for the bromine processing facility, which are expected to be completed late in the first quarter of 2024 or early in the second quarter of 2024.”

A summary of key financial metrics for the fourth quarter are as follows:

At the end of the fourth quarter, unrestricted cash was $52 million and availability under our credit agreements was $74 million. Liquidity at the end of the year was $126.3 million. As of February 26, 2024, liquidity was approximately $212 million, inclusive of the $75.0 million delayed draw feature that is available to TETRA for the bromine project. Liquidity is defined as unrestricted cash plus availability under our revolving credit facilities and includes the delayed draw feature. Long-term debt was $158 million, while net debt was $105 million. TETRA’s net leverage ratio was 1.13X at the end of the fourth quarter of 2023.

As previously announced, in January 2024, the Company entered into a definitive agreement for a $265 million credit facility with a maturity of January 2030, consisting of a $190 million funded term loan and a $75 million delayed draw term loan (collectively the “New Term Credit Agreement”) that refinanced the Company’s $163 million Term Credit Agreement outstanding as of December 31, 2023 and provides capital to advance the Company’s Arkansas bromine processing project. Pricing on the New Term Credit Agreement is the secured overnight financing rate plus 575 basis points, which is 50 basis points lower than the prior term loan. The Company used the proceeds to repay in full the balance of the previous Term Credit Agreement, pay transaction expenses and add cash to TETRA’s balance sheet.

Fourth quarter 2023 non-recurring charges and expenses are reflected on Schedule E and include $2.7 million of engineering and other consulting expenses incurred toward advancing the Company’s efforts to quantify the costs and economics on the potential development of its Arkansas bromine and lithium resources, inclusive of a FEED study and net of reimbursements from Saltwerx. Additionally, $4.9 million of other unusual charges including foreign currency losses in Argentina, restructuring and impairment charges and an adjustment to long-term incentives were also incurred in the quarter. Non-recurring charges for the calculation of adjusted income for the fourth quarter on Schedule F also include a $1.0 million tax provision related to an unfavorable court ruling on a tax matter involving the years 2014 to 2016.

Total year revenue of $626 million increased 13% from 2022 with international operations driving 65% of the revenue growth. Income from continuing operations improved by 2.4 times from income of $7.6 million in 2022 (inclusive of $11.4 million of unusual charges) to $25.5 million in 2023 (inclusive of $7.8 million of unusual charges). Adjusted EBITDA increased by $29 million on a revenue increase of $73 million. Adjusted EBITDA in 2023 was $107 million compared to $78 million in 2022, and Adjusted EBITDA margins increased 300 basis points to 17.1% from 14.1% in 2022. 2023 included unrealized gains on investments of $0.5 million while 2022 included unrealized gains on investments of $0.2 million. Excluding unrealized gains on investments in both periods, Adjusted EBITDA was up $28.4 million year-over-year or 36.4% growth and represents approximately 40% fall-through on the incremental revenue.

A summary of key financial metrics for the total year are as follows:

Completion Fluids & Products total year revenue for 2023 of $313 million increased $39.7 million from 2022. Income before taxes was $78.3 million (25% of revenue) inclusive of $2.3 million of non-recurring charges (mainly expenditures for our Arkansas assets net of a favorable insurance settlement).

    In addition to financial results determined in accordance with U.S. GAAP, this press release may include the following non-GAAP financial measures for the Company: adjusted net income per share; consolidated and segment Adjusted EBITDA; segment Adjusted EBITDA as a percent of revenue (“Adjusted EBITDA margin”); adjusted net income, adjusted free cash flow; net debt, net leverage ratio, and return on capital employed. The following schedules provide reconciliations of these non-GAAP financial measures to their most directly comparable U.S. GAAP measures. The non-GAAP financial measures should be considered in addition to, not as a substitute for, financial measures prepared in accordance with U.S. GAAP, as more fully discussed in the Company’s financial statements and filings with the Securities and Exchange Commission.

    Management believes that the exclusion of the special charges and credits from the historical results of operations enables management to evaluate more effectively the Company’s operations over the prior periods and to identify operating trends that could be obscured by the excluded items.

    Adjusted net income is defined as the Company’s income before noncontrolling interests and discontinued operations, excluding certain special or other charges (or credits), and including noncontrolling interest attributable to continued operations. Adjusted net income is used by management as a supplemental financial measure to assess financial performance, without regard to charges or credits that are considered by management to be outside of its normal operations.

    Adjusted net income per share is defined as the Company’s diluted net income per share attributable to TETRA stockholders excluding certain special or other charges (or credits). Adjusted net income per share is used by management as a supplemental financial measure to assess financial performance, without regard to charges or credits that are considered by management to be outside of its normal operations.

Adjusted EBITDA is defined as net income (loss) before taxes and discontinued operations, excluding impairments, exploration and pre-development costs, income from collaborative arrangement, certain special, non-recurring or other charges (or credits), interest, depreciation and amortization and certain non-cash items such as equity-based compensation expense. The most directly comparable GAAP financial measure is net income (loss) before taxes and discontinued operations. Exploration and pre-development costs represent expenditures incurred to evaluate potential future development of TETRA’s lithium and bromine properties in Arkansas. Such costs include exploratory drilling and associated engineering studies. Income from collaborative arrangement represents the portion of exploration and pre-development costs that are reimbursable by our strategic partner. Exploration and pre-development costs and the associated income from collaborative arrangement are excluded from Adjusted EBITDA because they do not relate to the Company’s current business operations. Adjustments to long-term incentives represent cumulative adjustments to valuation of long-term cash incentive compensation awards that are related to prior years. These costs are excluded from Adjusted EBITDA because they do not relate to the current year and are considered to be outside of normal operations. Long-term incentives are earned over a three-year period and the costs are recorded over the three-year period they are earned. The amounts accrued or incurred are based on a cumulative of the three-year period. Equity-based compensation expense represents compensation that has been or will be paid in equity and is excluded from Adjusted EBITDA because it is a non-cash item.

Adjusted EBITDA is used by management as a supplemental financial measure to assess financial performance, without regard to charges or credits that are considered by management to be outside of its normal operations and without regard to financing methods, capital structure or historical cost basis, and to assess the Company’s ability to incur and service debt and fund capital expenditures.

    Adjusted free cash flow is defined as cash from operations less capital expenditures net of sales proceeds and cost of equipment sold, less payments on financing lease obligations and including cash distributions to TETRA from CSI Compressco and cash from other investments. Management uses this supplemental financial measure to:

•assess the Company’s ability to retire debt;

•evaluate the capacity of the Company to further invest and grow; and

•to measure the performance of the Company as compared to its peer group.

    Adjusted free cash flow does not necessarily imply residual cash flow available for discretionary expenditures, as they exclude cash requirements for debt service or other non-discretionary expenditures that are not deducted.

    Net debt is defined as the sum of the carrying value of long-term and short-term debt on its consolidated balance sheet, less cash, excluding restricted cash on the balance sheet. Management views net debt as a measure of TETRA’s ability to reduce debt, add to cash balances, pay dividends, repurchase stock, and fund investing and financing activities.

Net leverage ratio is defined as debt excluding financing fees and discount on term loan and including letters of credit and guarantees, less cash divided by trailing twelve months adjusted EBITDA for credit facilities. Adjusted EBITDA for credit facilities consists of adjusted EBITDA described above, less non-cash (gain) loss on sale of investments, (gain) loss on sales of assets and excluding certain special or other charges (or credits). Management primarily uses this metric to assess TETRA’s ability to borrow, reduce debt, add to cash balances, pay distributions, and fund investing and financing activities.

Return on capital employed is defined as Adjusted EBIT divided by average net capital employed. Adjusted EBIT is defined as net income (loss) before taxes and discontinued operations, interest, and certain non-cash charges, and non-recurring adjustments. Net capital employed is defined as assets, excluding assets associated with discontinued operations, plus impaired assets, less cash and cash equivalents and restricted cash, and less current liabilities, excluding current liabilities associated with discontinued operations. Average net capital employed is calculated as the average of the beginning and ending net capital employed for the respective periods. Return on capital employed is used by management as a supplemental financial measure to assess the financial performance of the Company relative to assets, without regard to financing methods or capital structure.

The following reconciliation of net debt is presented as a supplement to financial results prepared in accordance with GAAP.

(1) Following the GP Sale on January 29, 2021, TETRA retained an interest in CSI Compressco representing approximately 3.7% of the outstanding common units as of December 31, 2023.
