Cash from operations was $10.2 million, free cash flow was negative $67.1 million on $78.4 million of capital spending, and liquidity reached $307.7 million, helped by $191.7 million of net proceeds from an underwritten Class A share offering and $70.0 million of debt repayments.

Positive

• Profitability and margins strengthened materially, with Q1 2026 Adjusted EBITDA rising to $77.6 million from $64.2 million sequentially and total gross margin improving to 17.8% from 13.1%, reflecting better performance across Water Infrastructure, Water Services and Chemical Technologies.
• Water Infrastructure delivered record revenue and higher growth outlook, generating $96.7 million of segment revenue and prompting management to raise full-year 2026 segment growth guidance to 25–30% year-over-year, supported by new long-term contracts and Northern Delaware infrastructure additions.
• Liquidity and balance sheet flexibility improved, as total liquidity increased to $307.7 million by March 31, 2026, aided by $191.7 million of net proceeds from an underwritten Class A share offering and $70.0 million of debt repayments under the sustainability-linked credit facility.

Negative

• Free cash flow was significantly negative, at $(67.1) million in Q1 2026, driven by $78.4 million of capital expenditures and a $61.7 million working capital build, and management now expects 2026 net capital expenditures to rise to $200–$250 million.

Insights

Energy services earnings analyst

Q1 showed margin-led growth, record infrastructure revenue and a stronger balance sheet, offset by heavy capex and negative free cash flow.

Select Water Solutions grew Q1 2026 revenue to $366.0 million, up 6% sequentially, and turned a prior-quarter loss into $9.4 million of net income. Gross margin expanded to 17.8%, and Adjusted EBITDA climbed to $77.6 million from $64.2 million, indicating stronger profitability across segments.

The Water Infrastructure segment was the standout, with record revenue of $96.7 million and gross margin before D&A of 56.2%. Management raised 2026 Water Infrastructure growth guidance to 25–30% year-over-year and detailed new long-term contracts and acquisitions in the Permian, Bakken, MidCon and Northeast regions that support long-lived, contracted volumes.

Cash flow was the main trade-off. Operating cash flow was $10.2 million, but free cash flow was negative $67.1 million due to $78.4 million of capital expenditures and infrastructure spending expected to reach $200–$250 million in 2026. An underwritten Class A share offering provided $191.7 million of net proceeds, boosting total liquidity to $307.7 million and allowing repayment of $70.0 million on the sustainability-linked credit facility.

Key Terms

6 terms

Adjusted EBITDA financial

"Adjusted EBITDA was $77.6 million in the first quarter of 2026 as compared to $64.2 million in the fourth quarter of 2025"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

free cash flow financial

"Free cash flow in the first quarter of 2026 and the fourth quarter of 2025 was ($67.1) million and ($4.6) million, respectively."

Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.

sustainability-linked credit facility financial

"borrowings outstanding under the term loan component of its sustainability-linked credit facility, with no amounts drawn on the revolving credit facility"

A sustainability-linked credit facility is a loan arranged so the borrower’s interest rate or other loan terms improve if the company meets agreed environmental, social or governance targets, and worsen if it misses them. Like a mortgage that lowers your rate when you reach energy-efficiency goals, it financially rewards measurable sustainability progress and matters to investors because it can lower borrowing costs, signal management’s priorities and affect future cash flow and credit risk.

minimum volume commitments financial

"we added three new minimum volume commitments (“MVCs”), two additional acreage dedications, two new right-of-first-refusal (“ROFR”) dedications"

Minimum volume commitments are contractual promises that one party will buy, sell or trade at least a set amount of a product, security or service over a defined period. For investors, these commitments matter because they create predictable baseline revenue or guaranteed demand — like a subscription minimum — but also can create liability or distort trading and liquidity if parties must meet the quota even when market conditions change.

right-of-first-refusal financial

"two new right-of-first-refusal (“ROFR”) dedications, and eight new interruptible agreements to our networks"

A right of first refusal is a contractual option that gives a holder the chance to buy an asset or investment on the same terms as a third-party offer before the seller can accept that outside buyer. For investors it matters because it can limit who ultimately acquires shares or assets, slow or block transactions, and affect price and liquidity—think of it like being first in line with the opportunity to match any offer before anyone else gets the ticket.

non-GAAP financial measures financial

"EBITDA, Adjusted EBITDA, gross profit before D&A, gross margin before D&A and free cash flow are not financial measures presented in accordance with accounting principles generally accepted"

Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.

Select Water Solutions Announces First Quarter 2026 Financial, Operational and Strategic Updates

Generated first quarter 2026 consolidated revenue of $366 million, an increase of $19 million or 6%, as compared to the fourth quarter of 2025

Increased net income by $11 million and improved adjusted EBITDA by $13 million sequentially during the first quarter of 2026 relative to the fourth quarter of 2025

Generated record quarterly Water Infrastructure revenue of $97 million during the first quarter of 2026, an increase of $16 million or 19%, as compared to the fourth quarter of 2025

Announces multiple new long-term contracted Water Infrastructure projects in the Permian, Bakken, MidCon and Northeast regions

Announces $28.6 million of acquisitions, closed during early May 2026, adding surface acreage and minerals, disposal capacity, water rights, and storage infrastructure in the Northern Delaware Basin

Gainesville, TX – May 5, 2026 – Select Water Solutions, Inc. (NYSE: WTTR) (“Select” or the “Company”), a leading provider of sustainable water and chemical solutions, today announced its financial and operating results for the quarter ended March 31, 2026.

John Schmitz, Chairman of the Board, President and CEO, stated, “The first quarter represented a strong start to the year for Select. During the first quarter of 2026, we delivered strong consolidated revenue growth, coupled with an increase in our gross margins, and drove an $11.5 million increase in net income and adjusted EBITDA growth of $13.5 million when compared to the fourth quarter of 2025. In addition to this operational performance, during the first quarter, we enhanced our balance sheet and financial flexibility and are well positioned to support our continued investment in infrastructure growth.

“In our Water Infrastructure segment, we increased both our recycling and disposal volumes during the first quarter of 2026, with approximately 1.4 million barrels of produced water recycled or disposed per day, resulting in record quarterly segment revenue of $96.7 million. We continue to leverage our system to get the maximum value out of our invested capital through increased commercialization and contracted service offering expansion. Since year-end, we have executed several new contracts across multiple basins that leverage our existing networks to provide incremental committed volumes, tie-in opportunities, or increased produced water flows and utilization through our system. For example, during the first quarter of 2026, we were able to leverage our market leading disposal position in the Northeast to sign a new long-term disposal dedication agreement while concurrently becoming the preferred last-mile logistics water transfer provider for this same customer. In total, since the beginning of the year we added three new minimum volume commitments (“MVCs”), two additional acreage dedications, two new right-of-first-refusal (“ROFR”) dedications, and eight new interruptible agreements to our networks across the Permian, Northeast, Bakken and MidCon regions. Subsequent to quarter end, we also closed on multiple acquisitions in the Northern Delaware Basin, adding approximately 4,000 acres of surface and minerals, 30,000 barrels per day of disposal capacity, 1,800-acre feet of annual water rights and 500,000 barrels of storage across Texas and New Mexico. We expect these acquisitions to integrate efficiently and bolster the operational and economic potential of our Northern Delaware network. We will continue to pursue opportunities to tactically add to our footprint in the region.

“Supported by the strong outperformance during the first quarter, our Water Infrastructure segment is well on track to exceed the high end of our previously guided range of 20 – 25% year-over-year growth. While we expect a relatively steady second quarter for the segment, with additional projects coming online over the course of the second and third quarters, we expect continued growth throughout the second half of 2026, leading us to increase our full-year guidance to 25 – 30% year-over-year growth for the segment. With additional infrastructure contracts in hand and near-term network integration capital requirements associated with our recent acquisitions, we now expect net capital expenditures in 2026 to increase to $200 – $250 million.

“Our Chemical Technologies segment performed as expected in the first quarter and we expect strong double-digit percentage sequential revenue growth during the second quarter. With continued demand for new product development in both our core friction reducer product lines as well as our specialty surfactant product offerings, we believe we are well positioned for future growth opportunities.

“Our Water Services segment meaningfully outperformed our expectations during the first quarter, with revenue growth of more than 7%, and this segment remains well positioned to capitalize on any activity uplift in the market associated with the current commodity price environment. Altogether we expect continued strong performance, and on a consolidated basis, we anticipate Adjusted EBITDA in the second quarter at an estimated $77 – $80 million.

“In summary, I am pleased with our financial performance in the first quarter of 2026, and I am very excited as the ongoing evolution of our strategy continues to materialize. We look forward to building on these recent successes to continue serving our valued customers, employees, and stakeholders,” concluded Schmitz.

The Water Services segment revenues increased 7.2% sequentially, driven by improved activity levels, strong gains in our water transfer business and increased water sales. For the second quarter of 2026, the Company expects revenues to modestly decrease low single-digit percentages, as certain spot market water sales are not expected to recur.

Subsequent to the end of the first quarter of 2026, Select acquired disposal facilities, water rights and storage infrastructure in the Delaware Basin, adding 30,000 barrels per day of additional disposal capacity and 500,000 barrels of storage capacity, to help support our growing infrastructure development activities in the Permian Basin.

Delaware Basin Ranch Acquisition

Subsequent to the end of the first quarter of 2026, Select acquired the Black River Ranch (“BRR”) in Eddy County, New Mexico. Approximately 70% of the acquisition was funded with an agricultural loan, with the remaining balance funded from cash on hand. BRR encompasses 3,753 acres of fee land and 710 acres of federal lease land. Additionally, the BRR includes 1,800-acre feet of annual water rights. The BRR surface will provide additional development opportunities for Select’s Northern Delaware network buildout while also providing the Company with direct revenues associated with the water rights, irrigated agricultural cropland, and other surface-related fees and mineral interests.

Cautionary Statement Regarding Forward-Looking Statements

All statements in this communication other than statements of historical facts are forward-looking statements which contain our current expectations about our future results. We have attempted to identify any forward-looking statements by using words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast” “intend,” “may,” “plan,” “potential,” “preliminary,” “project,” “see,” “should,” “will,” and other similar expressions. Examples of forward-looking statements include, but are not limited to, the expectations of plans, business strategies, objectives and growth, projected financial results and future financial and operational performance, expected capital expenditures, our share repurchase program and future dividends. Although we believe that the expectations reflected, and the assumptions or bases underlying our forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. Such statements are not guarantees of future performance or events and are subject to known and unknown risks and uncertainties that could cause our actual results, events or financial positions to differ materially from those included within or implied by such forward-looking statements. These risks and uncertainties include the risks that the benefits contemplated from our recent acquisitions may not be realized, the ability of Select to successfully integrate the acquired businesses’ operations, including employees, and realize anticipated synergies and cost savings and the potential impact of the consummation of the acquisitions on relationships, including with employees, suppliers, customers, competitors and creditors. Factors that could materially impact such forward-looking statements include, but are not limited to: global economic distress, including that resulting from the sustained Russia-Ukraine war and related economic sanctions, instability and continued hostilities in the Middle East, including military conflict involving Iran, instability in Venezuela, economic uncertainty as a result of changing trade policies, disruptions in global oil and gas markets; inflation and high interest rates, each of which may decrease demand for oil and natural gas or contribute to volatility in the prices for oil and natural gas, which may decrease demand for our services; the ability to source certain raw materials and other critical components or manufactured products globally on a timely basis from economically advantaged sources, including any delays and/or supply chain disruptions due to increased hostilities in the Middle East; actions taken by the members of the Organization of the Petroleum Exporting Countries (“OPEC”) and Russia (together with OPEC and other allied producing countries, “OPEC+”) with respect to oil production levels and announcements of potential changes in such levels, including the ability of the OPEC+ countries to agree on and comply with announced supply limitations, which may be exacerbated by military conflict in the Middle East involving Iran and the resumption of sales of previously sanctioned oil from Venezuela and Russia; the impact of central bank policy actions, such as sustained, elevated interest rates in response to, among other things, high rates of inflation, and disruptions in the bank and capital markets; the degree to which consolidation among our customers may affect spending on U.S. drilling and completions activity, including the recent consolidation in the Permian Basin; impacts related to changing U.S. and foreign trade policies, including increased trade restrictions or tariffs; the impact of changes in diplomatic and trade relations, and the results of countermeasures and any tariff migration initiatives; changes in safety, health, environmental and other governmental policy

and regulation; the enactment or promulgation of new laws or regulations or changes or modifications in existing laws, regulations, rules or governmental policies with respect to taxation; the level of capital spending and access to capital markets by oil and gas companies in response to changes in commodity price or reduced demand; the potential deterioration of our customers’ financial condition, including defaults resulting from actual or potential insolvencies; trends and volatility in oil and gas prices, and our ability to manage through such volatility; the impact of current and future laws, rulings, governmental regulations and policies, including those related to accessing water, disposing of wastewater, transferring produced water, interstate freshwater and produced water transfer, chemicals, carbon pricing, pipeline construction, emissions, hydraulic fracturing, leasing, permitting or drilling on federal lands and various other environmental matters; regional impacts to our business, including our key infrastructure assets within the Permian Basin, the Bakken, and the Haynesville regions; capacity constraints on regional oil, natural gas and water gathering, processing and pipeline systems that result in a slowdown or delay in drilling and completion activity, and thus a decrease in the demand for our services in our core markets; the impact of regulatory and related policy actions by federal, state and/or local governments, such as the Inflation Reduction Act of 2022, which may negatively impact the future production of oil and gas in the U.S., thereby reducing demand for our services; our ability to hire and retain key management and employees, including skilled labor; our access to capital to fund expansions, acquisitions and our working capital needs and our ability to obtain debt or equity financing on satisfactory terms, or at all; our health, safety and environmental performance; the impact of competition on our operations; the degree to which our exploration and production customers may elect to operate their water-management services in-house rather than source these services from companies like us; our level of indebtedness and our ability to comply with covenants contained in our sustainability-linked credit facility or future debt instruments; delays or restrictions in obtaining permits by us or our customers; constraints in supply or availability of equipment used in our business; the impact of advances or changes in well-completion technologies or practices that result in reduced demand for our services, either on a volumetric or time basis; changes in global political or economic conditions, generally, and in the markets we serve, including the rate of inflation and potential economic recession; acts of terrorism, war or political or civil unrest in the U.S. or elsewhere, such as the Russia-Ukraine war, the instability and continued hostilities in the Middle East, including military conflict involving Iran and any potential conflict with Venezuela; information technology failures or cyberattacks; accidents, weather, natural disasters or other events affecting our business; and the other factors discussed or referenced in the “Risk Factors” section of our most recent Annual Report on Form 10-K and those set forth from time to time in our other filings with the SEC. Investors should not place undue reliance on our forward-looking statements. Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events, changed circumstances or otherwise, unless required by law.

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, 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/(gains) on unconsolidated entities plus tax receivable agreements expense and less remeasurement gain on business combination. 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 (loss) 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.
