Select Water Solutions Announces Third Quarter 2025 Financial and Operational Results and Other Strategic Updates

Generated revenue of $322 million and cash flow from operating activities of $72 million during the third quarter of 2025

Increased Chemical Technologies revenue and gross profit by 13% and 34%, respectively, in the third quarter of 2025 as compared to the second quarter of 2025

Announced multiple new long-term contracted Water Infrastructure projects in the Permian Basin backed by approximately 65,000 acres of additional leasehold and right-of-first-refusal (“ROFR”) acreage dedications

Enhanced multiple existing Water Infrastructure long-term contracts covering 309,000 acres of dedication through the addition of long-term contracted last-mile water transfer and logistics services to the benefit of Water Services

Gainesville, TX – November 4, 2025 – Select Water Solutions, Inc. (NYSE: WTTR) (“Select” the “Company”, “we” or “us”), a leading provider of sustainable water and chemical solutions, today announced its financial and operating results for the quarter ended September 30, 2025, as well as other strategic updates.

John Schmitz, Chairman of the Board, President and CEO, stated, “During the third quarter of 2025, Select advanced its strategic objectives to increase Water Infrastructure scale and posted strong Chemical Technologies sequential growth in both revenues and gross margins, while furthering our Water Services rationalization and efficiency efforts.

“We continue to advance our market leading recycling position and to responsibly grow our disposal capacity with new contract awards, organic expansion and acquisitions. Contributing to our future growth and expansion, in the third quarter we signed several contracts adding approximately 65,000 additional acres under long-term dedication supporting integrated gathering, recycling, and disposal solutions. With a heightened focus on produced water disposal challenges and pore space availability to inject the growing produced water volumes in the Permian Basin, we believe there is a current and growing need for comprehensive water midstream solutions in the region. We are proud to currently recycle nearly one million barrels per day in the Permian Basin, with the vast majority flowing through our fixed facilities, alleviating the need for these barrels to be injected into sub-surface reservoirs. To complement our recycling offering, we also continue to responsibly grow our Permian Basin disposal capacity, allowing us to provide vertically integrated water midstream and full lifecycle infrastructure solutions. Our expanding produced water systems incorporate dual-line, large-diameter gathering and distribution pipelines that are connected to centralized recycling and disposal facilities, providing critical optionality on how we manage produced water for our customers. Longer-term, we expect our emerging beneficial reuse solutions to provide further optionality as well. Furthermore, we continue to advance our mineral extraction solutions that are synergistic with our recycling efforts and the growing produced water volumes we capture. This includes our recently announced groundbreaking of Texas’s first commercial produced water lithium extraction facility in the Haynesville Shale region. This project is expected to provide Select with long-term, royalty-based revenues through the further monetization of our existing produced water volumes moving through our existing network. We’re excited about this initial project and look forward to further assessing Select’s portfolio for further revenue and margin enhancement opportunities.

“Looking at our latest infrastructure contract awards more specifically, we executed a 12-year agreement with an operator for both its Texas and New Mexico operations, encompassing water recycling, storage, disposal and pipeline gathering and distribution. The Northern Delaware acreage in the agreements will connect into our ongoing New Mexico network expansion. These agreements add approximately 60,000 acres under dedication while extending our New Mexico infrastructure southward into additional emerging plays on the Texas side of the basin. We anticipate that these latest project awards will continue to drive increased long-term utilization across our approximately 1.8 million barrels per day of recycling capacity supported by over one million acres under dedication or ROFR in New Mexico alone. Something else that I’m very excited about, during the third quarter, we also signed a new long-term contract for water transfer, or last-mile logistics services, with a key customer in the Permian Basin, enhancing more than 300,000 acres under existing dedication with newly contracted water transfer services alongside existing water recycling, gathering and disposal dedications. I believe this shows the strength of Select’s unique integrated value proposition and this customer’s trust in our automated water transfer and logistics services.

“Separately, in the Midland Basin, we executed a 7-year agreement with a major integrated operator to tie into and expand one of our existing recycling facilities and add complementary integrated disposal capacity to the facility. In addition to adding incremental dedicated acres, importantly, this project will create an integrated network out of an existing standalone facility. These developments are expected to be completed in the summer of 2026 and are anticipated to provide further growth potential for Select in the second half of 2026, driving full year 2026 Water Infrastructure growth of greater than 20%.

“In our Water Infrastructure segment, even in a challenging macro activity environment, we performed well operationally as fixed facility recycling volumes increased while disposal volumes were resilient during the third quarter. However, net skim oil sales volume and pricing were lower in the third quarter, accounting for the majority of the modest 2.5% revenue decline sequentially. Looking more near-term, we anticipate Water Infrastructure growing approximately 10% in the fourth quarter attributable to system expansion and commercialization efforts. During the third quarter, our Chemical Technologies segment saw very strong revenue and gross profit gains of 13% and 34%, respectively, driven by new product development and market share gains. On a consolidated basis, we anticipate a strong fourth quarter performance from our Water Infrastructure business and steady performance from Chemical Technologies to more than offset modest seasonal fourth quarter declines in our Water Services segment. As a result, we expect to hold consolidated revenues relatively steady during the fourth quarter with our consolidated Adjusted EBITDA increasing sequentially to an estimated $60 – $64 million.

“In light of our recent contract awards, we saw increased capex during the third quarter and are modestly increasing our 2025 net capital expenditures guidance range to $250 – $275 million. While this impacts near-term cash flows, we are excited to add to our growing backlog of projects under construction that should benefit Water Infrastructure growth in 2026. While we anticipate lower market activity levels to persist in the near-term, we are unwavering in our commitment to deliver to our shareholders an industry-leading water midstream and infrastructure growth platform comprised of strong free cash flowing assets, while upholding our commitment to a conservative balance sheet and a streamlined overall business.

“With strong infrastructure growth, a streamlined services business and a chemicals segment that continues to capture market share, we expect near term improvement in Q4 setting the stage for further growth in 2026. In summary, I am pleased with the ongoing advancement of our strategy and the way our organization responds to challenging environments. I also appreciate the continued dedication of our employees and the ongoing trust and support of our long-term shareholders.” concluded Schmitz.

The third quarter was impacted by the recent divestment of certain trucking operations, partially offset by the addition of key infrastructure assets in the Bakken region, associated with the Omni transaction, accounting for approximately $16 million or 37% of the net sequential revenue reduction. Furthermore, net income was impacted by a $14.9 million remeasurement gain associated with the Omni transaction.

For the third quarter of 2025, gross profit was $43.6 million, as compared to $57.8 million in the second quarter of 2025 and $62.4 million in the third quarter of 2024. Total gross margin was 13.5% in the third quarter of 2025 as compared to 15.9% in the second quarter of 2025 and 16.8% in the third quarter of 2024. Gross profit before depreciation, amortization and accretion (“D&A”) was $87.1 million for the third quarter of 2025 as compared to $98.8 million for the second quarter of 2025 and $101.4 million for the third quarter of 2024.

Adjusted EBITDA during the third quarter of 2025 was reduced by $1.5 million associated with the net benefit of a number of offsetting non-recurring and non-cash items. Non-cash compensation expense accounted for an additional $7.4 million adjustment during the third quarter of 2025. Please refer to the end of this release for reconciliations of gross profit before D&A (non-GAAP measure) to gross profit and of Adjusted EBITDA (non-GAAP measure) to net income.

Business Segment Information

The Water Infrastructure segment generated revenues of $78.8 million in the third quarter of 2025 as compared to $80.9 million in the second quarter of 2025 and $82.0 million in the third quarter of 2024. Gross margin before D&A for Water Infrastructure was 53.1% in the third quarter of 2025 as compared to 55.2% in the second quarter of 2025 and 56.7% in the third quarter of 2024. Water Infrastructure revenues decreased 2.5% sequentially relative to the second quarter of 2025, in line with Company guidance, driven primarily by a decrease in skim oil sales in the quarter. Looking ahead, the Company anticipates Water Infrastructure growing approximately 10% sequentially during the fourth quarter of 2025 with gross margins before D&A remaining consistently above 50%. With new projects coming online and additional recent contract awards, Select anticipates seeing growth of more than 20% in Water Infrastructure during 2026 on a year-over-year basis.

The Water Services segment generated revenues of $166.9 million in the third quarter of 2025 as compared to $215.7 million in the second quarter of 2025 and $234.0 million in the third quarter of 2024. Gross margin before D&A for Water Services was 18.0% in the third quarter of 2025 as compared to 19.6% in the second quarter of 2025 and 20.5% in the third quarter of 2024. Driven by the impact of the divested trucking operations in the Omni transaction and decreased activity levels across the U.S. Lower 48, Water Services segment revenues decreased 22.6% sequentially, though less than the Company’s prior guidance of a 25% reduction. For the fourth quarter of 2025, the Company expects segment revenues to decrease by low-to-mid-single digits, driven by lower activity levels and general seasonality. The Company expects gross margins before D&A to remain steady in the 19% – 20% range during the fourth quarter of 2025.

The Chemical Technologies segment generated revenues of $76.6 million in the third quarter of 2025 as compared to $67.7 million in the second quarter of 2025 and $55.3 million in the third quarter of 2024. Gross margin before D&A for Chemical Technologies was 19.9% in the third quarter of 2025 as compared to 17.5% in the second quarter of 2025 and 12.4% in the third quarter of 2024. Continued success in new product development has driven market share gains with higher margin product volumes, leading to revenue and margin performance that significantly outpaced our expectation and guidance of low-to-mid-single digit revenue declines and margins of 15% – 17%. For the fourth quarter of 2025, the Company anticipates relatively steady revenues with gross margin before D&A in the 18% – 20% range.

Cash Flow and Capital Expenditures

Cash flow provided by operations for the third quarter of 2025 was $71.7 million as compared to $82.6 million in the second quarter of 2025 and $51.9 million in the third quarter of 2024. Cash flow provided by operations during the third quarter of 2025 benefited from a $26.0 million decrease in net working capital, including a $31.8 million inflow from reduced accounts receivable balances.

Net capital expenditures for the third quarter of 2025 were $91.1 million, comprised of $95.2 million of capital expenditures partially offset by $4.2 million of cash proceeds from asset sales. Free cash flow in the third quarter of 2025 and the second quarter of 2025 was ($19.4) million and $10.8 million, respectively.

Cash flow used in investing activities in the third quarter of 2025 included $35.1 million of asset acquisitions and a business combination primarily to support ongoing water infrastructure and wastewater treatment development projects and reflects the closing of the Omni transaction.

Cash flows from financing activities during the third quarter of 2025 included $21.2 million of net inflows, primarily reflecting $30.0 million of net borrowings from the Company’s sustainability-linked credit facility, partially offset by $8.4 million of quarterly dividends and distributions paid.

Water Infrastructure Business Development and Acquisition Updates

Since the beginning of the third quarter of 2025, Select has signed multiple new long-term contracts for additional full lifecycle produced water gathering, recycling, disposal and distribution infrastructure projects in the Permian Basin. The combined capital expenditures associated with these new projects is expected to be approximately $25 million, with each project anticipated to be online in the second half of 2026.

Midland Basin Infrastructure Expansion

In the third quarter of 2025, Select signed a 7-year acreage dedication agreement for produced water gathering, recycling, disposal and the distribution of treated produced water for a major integrated operator in the Midland Basin. This expansion project will integrate into one of Select’s existing Midland Basin recycling facilities, creating a network out of a previously standalone facility. In conjunction with this contract, Select will build out 750,000 barrels of additional storage capacity and five miles of dual produced water gathering and treated produced water distribution lines, with the opportunity to further expand the produced water handling abilities at this facility with incremental recycling and disposal capacity at Select’s discretion to further serve this customer. This agreement is supported by an approximately 5,400 acre dedication for the gathering, recycling and disposal of produced water and the delivery of treated produced water.

Northern Delaware Basin Dedication

In the third quarter of 2025, Select signed a 12-year acreage dedication agreement for produced water gathering, recycling, disposal and the distribution of treated produced water for a private operator in the Northern Delaware Basin, integrating into Select’s New Mexico system. This agreement is supported by an approximately 3,000 acre dedication for the gathering, recycling and disposal of produced water and the delivery of treated produced water.

Winkler County Infrastructure Expansion and Right-of-First Refusal Execution

During the third quarter of 2025, Select signed a 12-year contract to support the operational expansion into Winkler County, Texas for an existing key customer in the Delaware basin. As part of the agreement, Select will construct a dual-lined large diameter pipeline to tie the facilities into Select’s existing Lea County, New Mexico network in order to take away and recycle and/or dispose of the operator’s produced water from the dedicated area and supply frac water in the dedicated area. This agreement is supported by approximately 16,500 dedicated acres and more than 40,000 acres under ROFR for future development opportunities. The full project is expected to be operational by the end of the second quarter of 2026.

Long-Term Delaware Basin Water Transfer Agreement

In the third quarter of 2025, Select signed an agreement to be the exclusive water transfer and last-mile logistics provider for all water needs in connection with a key customer’s drilling and completions operations in the service area, comprised of the operator’s entire leasehold in the Delaware Basin, accounting for approximately 309,000 of combined leasehold and ROFR acres. This effectively integrates water transfer, a key Water Services offering, across multiple existing full lifecycle gathering, recycling and disposal Water Infrastructure contracts previously signed with the customer in the second and third quarters of 2025 that paved the way for this expansive water transfer agreement.

Strategic Infrastructure Acquisitions

During the third quarter of 2025, Select closed on multiple strategic Infrastructure acquisitions across the Permian, Northeast, Bakken and MidCon regions. Additionally, in conjunction with the recently executed Winkler County, Texas infrastructure expansion project, Select acquired certain disposal facilities in Winkler County, Texas. In total, these recent acquisitions include 78,000 barrels per day of incremental permitted disposal capacity. Within the Permian Basin, Select added three disposal facilities in the Northern Delaware Basin within New Mexico. These facilities will be efficiently networked into Select’s existing Northern Delaware infrastructure system buildout in Eddy County, New Mexico. Select also added three additional disposal facilities in the Northeast region, further consolidating a market leading position in the region.

Furthermore, Select closed on the previously announced strategic asset swap transaction with Omni Environmental Services, adding landfill, treatment and disposal assets in the Bakken region in exchange for certain trucking operations in the Northeast, Bakken and MidCon regions and certain cash and stock consideration (“Omni Transaction”).

Comparison of Non-GAAP Financial Measures

EBITDA, Adjusted EBITDA, gross profit before depreciation, amortization and accretion (“D&A”), gross margin before D&A and free cash flow are not financial measures presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). We define EBITDA as net income (loss), plus interest expense, income taxes and depreciation, amortization and accretion. We define Adjusted EBITDA as EBITDA plus any impairment and abandonment charges or asset write-offs pursuant to GAAP, plus non-cash losses on the sale of assets or subsidiaries less remeasurement gains on fixed assets related to business combinations, non-recurring compensation expense, non-cash compensation expense, and non-recurring or unusual expenses or charges, including severance expenses, transaction costs, or facilities-related exit and disposal-related expenditures, plus/(minus) foreign currency losses/(gains), plus/(minus) losses/(earnings) on unconsolidated entities and plus tax receivable agreements expense. We define gross profit before D&A as revenue less cost of revenue, excluding cost of sales D&A expense. We define gross margin before D&A as gross profit before D&A divided by revenue. We define free cash flow as net cash provided by (used in) operating activities less purchases of property and equipment, plus proceeds received from sale of property and equipment. EBITDA, Adjusted EBITDA, gross profit before D&A, gross margin before D&A and free cash flow are supplemental non-GAAP financial measures that we believe provide useful information to external users of our financial statements, such as industry analysts, investors, lenders and rating agencies because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure (such as varying levels of interest expense), asset base (such as depreciation, amortization and accretion) and non-recurring items outside the control of our management team. We present EBITDA, Adjusted EBITDA, gross profit before D&A, gross margin before D&A and free cash flow because we believe they provide useful information regarding the factors and trends affecting our business in addition to measures calculated under GAAP.

Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. Gross profit and gross margin are the GAAP measures most directly comparable to gross profit before D&A and gross margin before D&A, respectively. Net cash provided by (used in) operating activities is the GAAP measure most directly comparable to free cash flow. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as an analytical tool due to exclusion of some but not all items that affect the most directly comparable GAAP financial measures. You should not consider EBITDA, Adjusted EBITDA, gross profit before D&A, gross margin before D&A or free cash flow in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA, Adjusted EBITDA, gross profit before D&A, gross margin before D&A and free cash flow may be defined differently by other companies in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

For forward-looking non-GAAP measures, the Company is unable to provide a reconciliation of the forward-looking non-GAAP financial measures to their most directly comparable GAAP financial measure as the information necessary for a quantitative reconciliation, including potential acquisition-related transaction costs as well as the purchase price accounting allocation of the recent acquisitions and the resulting impacts to depreciation, amortization and accretion expense, among other items is not available to the Company without unreasonable efforts due to the inherent difficulty and impracticability of predicting certain amounts required by GAAP with a reasonable degree of accuracy at this time.
