GAINESVILLE, Texas, Aug. 5, 2025 /PRNewswire/ -- 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 June 30, 2025, as well as other strategic updates.

John Schmitz, Chairman of the Board, President and CEO, stated, "During the second quarter of 2025, Select improved its profitability and cash flow while continuing to advance its strategic objectives to grow Water Infrastructure scale and margin. In the second quarter of 2025, we increased net income by 22% and adjusted EBITDA by 13% when compared to the first quarter of 2025 and improved consolidated margins despite modestly reduced consolidated revenue levels.

"In our Water Infrastructure segment, we increased both our recycling and disposal volumes during the second quarter of 2025, resulting in sequential increases in revenue and gross profit of approximately 12% and 17%, respectively. Gross margins before D&A for the Water Infrastructure segment increased to 55% during the quarter, which is a testament to the team's ability to add accretive volumetric throughput across our large-scale water networks.

"We continue to add to our growing backlog with multiple new key contracts that bolster our industry-leading recycling footprint while adding complementary disposal capacity in the Permian Basin. Importantly, we have also executed on, or are now underway with, multiple strategic opportunities to rationalize our Water Services segment in support of our rapidly growing Water Infrastructure platform. Combined, we expect that these opportunities will drive additional growth in our Water Infrastructure segment and further accelerate the weighting of our cash flows towards more contracted and production-oriented offerings.

"During July 2025, we closed on a unique transaction with OMNI Environmental Solutions. As part of this transaction, we added to our Water Infrastructure segment and expanded our market-leading solids management footprint in the Bakken region, acquiring an additional landfill, a processing and treatment plant, disposal facilities and oil reclamation assets in the region. In exchange, OMNI acquired trucking and rental operations from Select in the Northeast, MidCon and Bakken regions. While we anticipate that this transaction will meaningfully reduce our Water Services revenues in the short-term, we expect it will improve our consolidated margins over time and significantly reduce our operational risk profile and complexity in multiple basins. We intend to upgrade and expand the acquired landfill and treatment assets during the second half of 2025, adding high-margin growth potential to our Water Infrastructure segment starting in 2026. Importantly, this transaction also allowed us to preserve the jobs of approximately 7% of our consolidated workforce, who have transitioned to OMNI with the divested trucking operations from our Water Services segment. 

"While the OMNI transaction is a strong step towards rationalizing the Water Services portfolio, we see additional opportunity to unlock value from our strategic assets within our Water Services segment. Accordingly, we are now formally evaluating a range of capital structure options for Peak Rentals, our equipment rental business, to accelerate growth, improve access to capital, and advance the continued optimization of the Water Services portfolio. Peak operates a scaled, integrated platform offering wellsite equipment, well pressure and flow control systems, and notably, an emerging distributed power generation business line.  Peak has long been a leader in deploying traditional distributed power solutions into the energy markets and, more recently, Peak has capitalized on rapidly growing demand for its natural gas generators and proprietary battery power systems, alongside its existing diesel generator fleet. With the increasing off-grid power development and production trends, there is a growing need for distributed power solutions both within and beyond the traditional oilfield and we believe Peak is well positioned as a vertically integrated business to grow and support these vectors. To support this momentum and ensure the business has access to dedicated growth capital, Select has partnered with Scott McNeill, a proven executive in the energy and power sectors. Scott joins us as CEO of Peak and is leading the strategic development and transaction planning for the business. Scott has been instrumental in the formation, leadership and monetization of multiple successful energy companies and brings deep experience in both operations and capital formation.

"While the ultimate outcome is still to be determined, we expect to preserve continued economic exposure to Peak's future growth and value creation in the distributed power space while maintaining long-term strategic alignment to support our core Water Infrastructure growth strategy. The Company does not intend to provide further updates unless and until a specific transaction is approved. Ultimately, each of the OMNI and Peak initiatives are aimed at focusing Select's near-term priorities and capital towards its core strategy of building and delivering ratable, repeatable Water Infrastructure growth, and specifically the continued buildout of our large-scale Northern Delaware Basin infrastructure network in New Mexico.  

"Looking at our latest infrastructure contract awards in New Mexico more specifically, the largest of the new agreements is a 12-year contract, encompassing water recycling, storage, disposal and pipeline gathering and distribution in the Northern Delaware Basin in Eddy County, New Mexico that will connect into our ongoing Eddy County network expansion that we announced last quarter. This new agreement adds approximately 42,000 dedicated acres and 235,000 right-of-first-refusal acres and meaningfully extends our Eddy County infrastructure further southward, traversing valuable and prolific acreage. As part of this agreement, the customer has also agreed to convey ownership of their existing disposal infrastructure in the dedicated area to Select. Separately, in the quarter, we executed an additional agreement with a key existing customer to assume operatorship of their existing recycling infrastructure in Lea County, New Mexico. Select will connect the assumed facilities into Select's expansive Northern Delaware Network while also adding an additional approximate 17,000 acre dedication and 150,000 acres under right-of-first-refusal for future expansion opportunities in both Lea and Eddy Counties, New Mexico. I believe it is a strong endorsement of Select's operating capabilities, reliability and unique customer value proposition that each of these customers is, in effect, willing to convey direct ownership and operatorship of certain of their existing assets to Select to operate, not only in support of their own operations, but for broader commercialization as well. Once online, these additional assets and dedications are anticipated to provide further growth potential for Select in 2026. Pro forma for the build out of the latest project awards, we expect to have approximately 1.8 million bpd of recycling capacity supporting over one million acres under dedication or right-of-first-refusal in New Mexico alone.

"We maintain high confidence around the contracted Water Infrastructure growth opportunities underway, and believe the segment is positioned to see strong 20% year-over-year growth in 2026. Looking more near-term, we anticipate Water Infrastructure revenue to be flat-to-modestly down in the third quarter as under construction assets are interconnected and commissioned and we see some modest variability in interruptible activity. However, with new assets coming online, a strong water inventory backlog and visible customer demand, we expect to see 10% growth for the Water Infrastructure segment in the fourth quarter of 2025, setting the stage for further growth in 2026. Looking at our consolidated business, we have begun to experience the impacts of reduced activity levels in the latter parts of the second quarter, particularly in our Water Services segment, and these lower activity levels are expected to persist throughout the remaining balance of the year. On a consolidated basis, we anticipate the relatively steady third quarter performance in our Water Infrastructure business to be offset by sequential declines elsewhere, primarily from our Water Services segment, driven by the impacts of both the OMNI divestments and reduced macro activity levels. As a result, we expect our consolidated Adjusted EBITDA in the third quarter to decline sequentially to an estimated $55 – $60 million, with a tick-up in consolidated gross profit and Adjusted EBITDA expected in the fourth quarter driven by strong sequential growth in Water Infrastructure.

"We maintain our 2025 net capital expenditures guidance of $225 million to $250 million, with a bias to the higher-end resulting from the latest announced awards, better positioning us for 2026 and beyond. While near-term cash flow is expected to be modestly impacted by reduced activity levels, we are well positioned to fund our Water Infrastructure growth projects while maintaining a healthy balance sheet in this challenging market.

"In summary, I am pleased with our financial performance in the second quarter of 2025 and the ongoing execution of our strategy. While we expect activity softness to persist throughout the U.S. Lower 48 in the second half of 2025, we anticipate continued resiliency and growth from our Water Infrastructure segment during the second half of 2025 and well into 2026, underwritten by a growing backlog of contracted projects. Strategically, we intend to continue to core-up the business around our integrated full-life cycle water thesis and more resilient earnings streams. As we evaluate strategic alternatives for our Peak business, we are excited for the prospective opportunity to support Peak's delivery of leading-edge power solutions and energy infrastructure, while also providing potential funding for further Water Infrastructure growth for Select. I am as excited as ever in our strategic direction and, as Select continues to evolve, I appreciate the continued dedication of our employees and ongoing trust and support of our long-term shareholders." concluded Schmitz.

Business Segment Information

The Water Infrastructure segment generated revenues of $80.9 million in the second quarter of 2025 as compared to $72.4 million in the first quarter of 2025 and $68.6 million in the second quarter of 2024. Gross margin before D&A for Water Infrastructure was 55.2% in the second quarter of 2025 as compared to 53.7% in the first quarter of 2025 and 51.0% in the second quarter of 2024. Water Infrastructure revenues increased 11.7% sequentially relative to the first quarter of 2025, ahead of Company guidance, driven by increases in both our recycled and disposal volumes. Looking ahead, the Company anticipates Water Infrastructure revenue to be flat-to-down low single-digit percentages sequentially during the third quarter of 2025 with gross margins before D&A remaining consistently above 50%. Looking ahead, the Company expects 10% sequential quarterly growth in the Water Infrastructure segment financial performance during the fourth quarter of 2025 and 20% year-over-year growth in 2026.

The Water Services segment generated revenues of $215.7 million in the second quarter of 2025 as compared to $225.6 million in the first quarter of 2025 and $230.0 million in the second quarter of 2024.  Gross margin before D&A for Water Services was 19.6% in the second quarter of 2025 as compared to 19.5% in the first quarter of 2025 and 22.5% in the second quarter of 2024. Driven by declining activity levels and a reduction in traditional freshwater sourcing sales, Water Services segment revenues decreased 4.4% sequentially, though less than expected. For the third quarter of 2025, the Company expects segment revenues to decrease by approximately 25%, driven by the material impact of the divested trucking operations from the OMNI transaction and decreased activity levels across the U.S. Lower 48. The Company expects gross margins before D&A to remain steady in the 19% - 20% range during the third quarter of 2025.

The Chemical Technologies segment generated revenues of $67.7 million in the second quarter of 2025 as compared to $76.3 million in the first quarter of 2025 and $66.6 million in the second quarter of 2024.  Gross margin before D&A for Chemical Technologies was 17.5% in the second quarter of 2025 as compared to 15.2% in the first quarter of 2025 and 16.4% in the second quarter of 2024. While revenues sequentially decreased more than expected, stronger than anticipated margin performance led to overall net sequential gains in gross profit before D&A during the second quarter as continued success in new product development has driven higher margin product volumes. For the third quarter of 2025, the Company anticipates revenue to decrease low-to-mid single-digit percentages and gross margin before D&A to remain relatively steady in the 15% – 17% range, as declining industry activity levels impact the business.

Cash Flow and Capital Expenditures

Cash flow provided by operations for the second quarter of 2025 was $82.6 million as compared to cash flow used in operations of $5.1 million in the first quarter of 2025 and cash flow provided by operations of $83.1 million in the second quarter of 2024. Cash flow provided by operations during the second quarter of 2025 benefited from a $23.3 million decrease in net working capital, including a $28.3 million inflow from reduced accounts receivable balances.

Net capital expenditures for the second quarter of 2025 were $71.7 million, comprised of $79.4 million of capital expenditures partially offset by $7.7 million of cash proceeds from asset sales. Free cash flow in the second quarter of 2025 and the first quarter of 2025 was $10.8 million and ($51.5) million, respectively.

Cash flow used in investing activities in the second quarter of 2025 also included $3.2 million of asset acquisitions to support ongoing water infrastructure and wastewater treatment development projects.

Cash flows from financing activities during the second quarter of 2025 included $15.7 million of net inflows, primarily reflecting $25.0 million of borrowings from the sustainability-linked credit facility, partially offset by $8.3 million of quarterly dividends and distributions paid.

Balance Sheet and Capital Structure

Total cash and cash equivalents were $51.2 million as of June 30, 2025, as compared to $27.9 million as of March 31, 2025, and $20.0 million as of December 31, 2024. The Company had $250.0 million of borrowings outstanding under the term loan component of its sustainability-linked credit facility as of June 30, 2025 and March 31, 2025, with an additional $25.0 million of revolver borrowings outstanding as of June 30, 2025. There were no revolver borrowings outstanding as of March 31, 2025.

As of June 30, 2025, the borrowing base under the Company's sustainability-linked credit facility was $270.3 million, compared to $252.2 million as of March 31, 2025. Available borrowing capacity under the current sustainability-linked credit facility was approximately $228.1 million as of June 30, 2025 and 232.3 million as of March 31, 2025, after giving effect to outstanding borrowings and letters of credit totaling $42.2 million and $19.9 million, respectively.

Total liquidity was $279.3 million as of June 30, 2025, as compared to $260.2 as of March 31, 2025 and $134.8 million as of December 31, 2024. The Company had 101,527,407 weighted average shares of Class A common stock and 16,221,101 weighted average shares of Class B common stock outstanding during the second quarter of 2025.

Asset Swap Transaction with OMNI Environmental Solutions & Trucking Divestments

During July 2025, Select closed on an asset swap transaction with OMNI to concurrently acquire certain assets from OMNI to grow our Water Infrastructure portfolio and divest certain assets from Select's Water Services segment.

As part of the transaction, Select has expanded its market-leading solids management footprint in the Bakken region, acquiring a special waste landfill, a processing and treatment plant, disposal facilities and oil reclamation assets in Williams County, North Dakota. These assets complement Select's three active landfills and 20 active saltwater disposal wells in the Bakken region, and further expand the Company's service capabilities in the region into solids-liquids separation and enhanced oil reclamation and recovery. We intend to upgrade and expand the acquired landfill and treatment facility assets during the second half of 2025, adding incremental high-margin growth potential to our Water Infrastructure segment during 2026.

In exchange, OMNI received certain trucking and equipment rental operations in the Northeast, MidCon and Bakken regions, along with $7.5 million of cash consideration, $10.2 million of cash to compensate for retained net working capital and 862,069 Select Class A shares. As part of the transaction, Select and OMNI anticipate entering into regional trucking coordination agreements to provide ongoing logistical services to support Select's retained disposal infrastructure in each region.

Furthermore, and separate from the OMNI transaction, Select has exited the remainder of its trucking operations in the MidCon and Haynesville regions for additional cash consideration, thereby significantly reducing its remaining trucking footprint to the Permian, Eagle Ford and Rockies regions.

For the combined full-year 2024 and six-month year-to-date period ended June 30, 2025, the divested trucking operations represented approximately 37% and 20% of the trucking business unit's revenues and gross profit before D&A, respectively, and 10% and 5% of the Water Services segment revenues and gross profit, respectively.

Water Infrastructure Business Development Updates

Since the start of the second quarter of 2025, Select has executed 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 $40 million, with each project anticipated to be online in the first half of 2026.

Northern Delaware Basin – Eddy County Network Expansion

In the second quarter of 2025, Select signed a 12-year agreement for the construction and expansion of gathering, recycling, disposal and distribution infrastructure for a private operator in the Northern Delaware Basin, integrating into Select's Eddy County, New Mexico system that commenced construction last quarter. To support the agreement, Select plans to construct two new recycling facilities, adding up to 240,000 barrels per day of throughput capacity and up to four million barrels of storage capacity. The new facilities are expected to be connected and networked via 21 miles of dual-lined large diameter gathering and treated produced water pipelines. Additionally, as part of the agreement, the customer has agreed to fully convey ownership and operatorship of certain of its existing disposal facilities in the dedicated area to Select, which will be integrated into the network as well. This agreement is supported by an approximately 42,000 acre dedication for the gathering, recycling and disposal of produced water and the delivery of treated produced water, while also adding an additional 235,000 acres under right-of-first-refusal agreement for future development. We expect construction to be completed during the first half of 2026.

Northern Delaware Basin Infrastructure Expansion and Right-of-First Refusal Execution

In the second quarter of 2025, Select signed an 8-year contract to support the operational expansion for a large existing customer in the Northern Delaware basin. As part of the agreement, Select will assume operatorship of the customer's existing recycling infrastructure in the region and construct three miles of dual-lined large diameter pipeline to tie the facilities into Select's existing Lea County network. In conjunction with the new agreement, Select and the customer extended the contract term of another existing Lea and Eddy County recycling agreement and dedication by five additional years to match the 8-year term in the new agreement. These agreements are supported by approximately 17,000 additional dedicated acres, more than doubling the existing acreage dedication, while also adding an additional approximate 150,000 acres under right-of-first refusal for future development opportunities. The full project is expected to be operational by the first quarter of 2026.

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-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/(gains) 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 and rebranding 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.

The following table presents a reconciliation of free cash flow to net cash provided by operating activities, which is the most directly comparable GAAP measure for the periods presented:

The following table presents a reconciliation of EBITDA and Adjusted EBITDA to our net income, which is the most directly comparable GAAP measure for the periods presented:
