Rhea-AI Filing Summary

NPK International Inc. reported higher results for the quarter and first half ended June 30, 2026. Second-quarter revenues rose 20% to approximately $81.6 million, driven by a 16% increase in rental and service revenues and a 28% increase in product sales. Net income for the quarter grew to $12.0 million, with diluted earnings per share of $0.14.

For the first half of 2026, revenues increased 18% to $156.7 million and net income reached $22.4 million, or $0.26 per diluted share. Operating cash flow was $43.0 million, supporting $33.2 million of capital expenditures, largely for expanding the composite mat rental fleet and manufacturing capacity. Total debt was $10.6 million versus stockholders’ equity of $371.4 million, a debt-to-capitalization ratio of 2.8%, while a $150 million revolving Credit Facility remained undrawn with $148.1 million of availability.

The company continued executing its strategy to accelerate rental-led growth, integrate the Grassform acquisition in the U.K., and invest $40–$45 million to expand composite mat production capacity by about 50% through mid-2027. It also repurchased 0.2 million shares for $2.7 million in the first half under its share repurchase program.

Filing Explained

The filing adds equity awards settled in shares and discloses a director’s future 30,000-share sale plan beginning August 27, 2026.

NPK International filed this Form 10-Q as an unaudited quarterly report for the period ended June 30, 2026. It discloses equity awards with future vesting or performance conditions and a future director trading plan; the awards could increase the share count if settled in shares, while the plan concerns a holder's sale rather than a company issuance.

The Compensation Committee approved $0.2 million restricted stock units vesting in equal installments over three years, $0.1 million of non-employee director restricted stock awards vesting in full at an earlier specified date, and $0.2 million of performance-based restricted stock units settled in common shares, with payouts ranging from 0% to 200% of target. If awards settle in shares, additional shares increase the total share count and reduce an existing holder's percentage ownership absent offsetting changes.

On May 27, 2026, director Rose Robeson adopted a Rule 10b5-1 plan for sales of up to $30,000 shares, commencing August 27, 2026 and effective until May 27, 2027. A Rule 10b5-1 plan executes trades under a preset schedule or formula, and its adoption date does not state the reasons for individual trades.

For the quarter, the company reported no shares repurchased under its repurchase program; it acquired $223,731 shares surrendered for taxes on vesting, outside that program. The performance awards will be measured over periods ending in 2029 for the TSR component and through fiscal year 2028 for the RONCE component.

Credit Facility financial
"we entered into a U.S. senior secured revolving credit agreement (the “Credit Facility”)"
A credit facility is a flexible loan arrangement that allows a borrower to access funds up to a set limit whenever needed, similar to a company having an overdraft option on a bank account. It matters to investors because it indicates how easily a business can secure cash when required, affecting its ability to manage expenses, invest, or respond to financial challenges.
performance-based restricted stock units financial
"the issuance of 0.2 million performance-based restricted stock units to certain executive officers"
Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.
total shareholder return financial
"measured on the Company’s total shareholder return (“TSR”) as compared to the TSR of a designated peer group"
Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.
return on net capital employed financial
"based on the Company’s consolidated return on net capital employed (“RONCE”)"
discontinued operations financial
"Income (loss) from discontinued operations, net of tax"
Discontinued operations are parts of a company that it has decided to sell or shut down, and no longer plans to run in the future. This matters to investors because it helps them understand which parts of the business are ongoing and which are being phased out, providing a clearer picture of the company’s current performance and future prospects. Think of it like a store closing a department—it no longer contributes to sales or profits.
finance leases financial
"We maintain finance leases primarily related to transportation equipment."
A finance lease is a long-term rental arrangement where a company takes on most of the risks and rewards of owning an asset—like equipment or property—while making scheduled payments instead of a single purchase. Think of it like buying something on an installment plan: the item appears on the company’s books as an asset and a matching obligation, which affects reported debt, profits and cash flow and therefore can change how investors view the company’s financial strength and valuation.

NPK INTERNATIONAL INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Basis of Presentation and Significant Accounting Policies
NPK International Inc. is a worksite access solutions company that manufactures, sells, and rents recyclable composite matting products, along with a full suite of services, including planning, logistics, and site restoration. We serve customers in various markets including power transmission, oil and natural gas exploration and production, pipeline, renewable energy, petrochemical, construction and other industries within the United States and United Kingdom. We also sell our manufactured recyclable composite mats to customers around the world, with power transmission being the primary end-market.
The accompanying unaudited condensed consolidated financial statements of NPK International Inc. and our wholly-owned subsidiaries, which we collectively refer to as “NPK,” the “Company,” “we,” “our,” or “us,” have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the Securities and Exchange Commission, and do not include all information and footnotes required by the accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2025. Our fiscal year end is December 31, our second quarter represents the three-month period ended June 30, and our first half represents the six-month period ended June 30. The results of operations for the second quarter and first half of 2026 are not necessarily indicative of the results to be expected for the entire year. Unless otherwise noted, all currency amounts are stated in U.S. dollars.
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments necessary to present fairly our financial position as of June 30, 2026, our results of operations for the second quarter and first half of 2026 and 2025, and our cash flows for the first half of 2026 and 2025. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2025 is derived from the audited consolidated financial statements at that date.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. For further information, see Note 1 in our Annual Report on Form 10-K for the year ended December 31, 2025.

New Accounting Pronouncements
Standards Not Yet Adopted
Disaggregation of Income Statement Expenses. In November 2024, the FASB issued new guidance which requires entities to disclose additional information about specific expense categories, such as purchases of inventory, employee compensation, depreciation, and intangible asset amortization. This guidance will be effective for us for years beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted on either a prospective or retrospective basis. We are currently evaluating the impact of the new guidance on our consolidated financial statements and related disclosures.
Note 2 – Business Combinations and Discontinued Operations
Acquisition of Grassform Plant Hire Limited
On November 24, 2025, we completed the acquisition of Grassform Plant Hire Limited (“Grassform”), a U.K. market leader in ground protection and temporary roadway solutions and services.
The estimated purchase price for this acquisition is $49.0 million, as reduced by $1.2 million during the first half of 2026, or $44.8 million net of cash acquired, with $42.1 million funded at closing in 2025. The acquisition is subject to customary post-closing adjustments pursuant to completion accounts and certain other adjustment mechanisms. Additional consideration will be payable in 2026 based upon Grassform’s trailing twelve-month performance through February 28, 2026.
The Grassform acquisition has been recorded using the acquisition method of accounting and accordingly, preliminary amounts recognized for the assets acquired and liabilities assumed were recorded at their estimated fair values as of the acquisition date. The acquisition resulted in the recognition of $12.5 million in other intangible assets, consisting of customer relationships and tradename. The customer relationships and tradename are finite-lived intangible assets that will be amortized over periods of 15 years and 10 years, respectively. The excess of the total consideration of $28.4 million was recorded as goodwill, which is not deductible for U.S. tax purposes. The fair values of the identifiable assets acquired and liabilities assumed were based on our estimates and assumptions using various market, income, and cost valuation approaches, which are classified within level 3 of the fair value hierarchy.
Depreciation and amortization for the second quarter and first half of 2026 includes $1.5 million and $3.0 million, respectively, related to the acquired Grassform business.
The results of operations of Grassform are reported within the condensed consolidated statements of operations for the period subsequent to the date of the acquisition.
Sale of Fluids Systems Business
We previously operated a Fluids Systems business, which was historically reported as a separate operating segment, that provided drilling and completion fluids products and related technical services to customers for oil, natural gas, and geothermal projects. On September 13, 2024, we completed the sale of substantially all of the Company’s Fluids Systems segment (the “Sale Transaction”) to SCF Partners.
In the first quarter of 2026, we collected $5.0 million, plus applicable accrued interest, on a note receivable due from the Purchaser, as well as $0.5 million for certain pre-closing tax assets. As of June 30, 2026, approximately $1.3 million of net liabilities were included within the consolidated balance sheet, reflecting an estimated $2.1 million due to the Purchaser partially offset by $0.8 million due from the Purchaser.
Estimated liabilities due to the Purchaser includes payables of $0.6 million for pre-closing obligations attributable to the Fluids Systems business that are expected to be settled in the third quarter of 2026, as well as a $1.5 million estimated liability for contractual indemnifications related to various pre-closing contingencies of the Fluids Systems business. These estimated liabilities due to the Purchaser are included in accrued liabilities and other noncurrent liabilities in the condensed consolidated balance sheet. Estimated deferred consideration due from the Purchaser reflects the recovery of certain pre-closing assets, and are included in other receivables in the condensed consolidated balance sheet.
Our estimates for the fair value of liabilities due to the Purchaser and deferred consideration due from the Purchaser may change and any income or expense associated with such changes will be presented in discontinued operations. In the first half of 2026, we recognized a $0.5 million pre-tax gain on sale related to the resolution of certain contractual indemnifications related to the Sale Transaction. In addition, as part of the Sale Transaction, we retained the obligation to complete the closure of certain foreign subsidiaries that are no longer operational. We expect to continue to incur certain costs for these efforts until all such entities are closed.

Note 4 – Repurchase Program
Our Board of Directors has authorized a securities repurchase program available for repurchases of our common stock.
Our repurchase program authorizes us to purchase outstanding shares of our common stock in the open market or as otherwise determined by management, subject to certain limitations under the Credit Facility (as defined in Note 8) and other factors. The repurchase program has no specific term. Repurchases are expected to be funded from operating cash flows, available cash on hand, and borrowings under our Credit Facility. As part of the share repurchase program, our management has been authorized to establish trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934.
During the first half of 2026, we repurchased an aggregate of 0.2 million shares of our common stock under the repurchase program for a cost of $2.7 million. During the first half of 2025, we repurchased an aggregate of 2.6 million shares of our common stock under the repurchase program for a cost of $17.0 million.
As of June 30, 2026, we had $89.0 million remaining under the program.
Note 5 – Stock-Based and Other Long-Term Incentive Compensation
During the second quarter of 2026, the Compensation Committee of our Board of Directors (“Compensation Committee”) approved equity-based compensation awards to executive officers and other key employees consisting of an aggregate of 0.2 million restricted stock units, which will vest in equal installments over a three-year period. In addition, non-employee directors received grants of an aggregate of 0.1 million restricted stock awards, which will vest in full on the earlier of the day prior to the next annual meeting of stockholders following the grant date or the first anniversary of the grant date. The weighted average grant-date fair value was $15.29 per share for the restricted stock units and $15.52 per share for the
9


restricted stock awards. At June 30, 2026, 2.9 million shares remained available for awards under the 2015 Plan and 0.2 million shares remained available for awards under the 2014 Director Plan.
Also, during the second quarter of 2026, the Compensation Committee approved the issuance of 0.2 million performance-based restricted stock units to certain executive officers with the payout of shares for each executive ranging from 0% to 200% of target. The performance-based restricted stock units will be settled in shares of common stock, with 70% to be settled based on the relative ranking of the Company’s total shareholder return (“TSR”) as compared to the TSR of a designated peer group and 30% to be settled based on the Company’s consolidated return on net capital employed (“RONCE”), each measured over a three-year performance period. TSR performance for the 2026 grants will be determined based on the Company’s and peer group’s average closing share price for the 30-calendar day period ending May 31, 2029, adjusted for dividends, as compared to the 30-calendar day period ending June 1, 2026. RONCE performance for the 2026 grants will be determined based on the Company’s average three-year RONCE performance for the fiscal years ending December 31, 2026, 2027 and 2028.
The TSR portion of the performance-based restricted stock units had a grant-date fair value of $21.07 per share using a Monte-Carlo valuation model, which will be recognized ratably over the service period. Assumptions used in the model included a risk-free interest rate of 3.9%, an expected life of 3 years, and an expected volatility of 37.5%. The RONCE portion of the performance-based restricted stock units had a grant-date fair value of $15.29 per share, which will be recognized ratably over the service period using the probable number of shares expected to vest based on the RONCE performance condition.
In addition, in May 2026, the Compensation Committee modified the retirement eligibility terms applicable to our outstanding long-term incentive awards, including unvested grants from 2024 and 2025. Selling, general and administrative expenses (“SG&A”) for the second quarter of 2026 includes a $0.9 million charge reflecting the acceleration of compensation expense for such awards for retirement eligible executive officers and other employees.

Credit Facility. In June 2025, we entered into a U.S. senior secured revolving credit agreement (the “Credit Facility”) with a group of lenders that provides financing of up to $150 million available for borrowings (inclusive of letters of credit), which can be increased up to $250 million, subject to certain conditions. The Credit Facility and the loans made under the Credit Facility are secured by a first priority lien on substantially all of the personal property of the Company and its significant U.S. subsidiaries as guarantors (subject to customary exceptions and exclusions). The Credit Facility will mature in June 2030.
As of June 30, 2026, we had no outstanding borrowings and $1.9 million in outstanding letters of credit, resulting in $148.1 million of remaining availability under the Credit Facility.
Under the terms of the Credit Facility, we may elect to borrow at a variable interest rate based on either the Term SOFR rate or an alternate base rate plus, in each case, a per annum applicable margin. The applicable margin will range from 1.75% to 2.25% for Term SOFR loans and 0.75% to 1.25% for alternate base rate loans, based on the consolidated leverage ratio (as defined in the Credit Facility) as of the last day of the most recent fiscal quarter. We are also required to pay a commitment fee on the unused portion of the Credit Facility ranging from 0.25% to 0.35% per annum based on the consolidated leverage ratio.
As of June 30, 2026, the applicable margin for loans under the Credit Facility was 1.75% for Term SOFR loans and 0.75% for alternate base rate loans, and the applicable commitment fee was 0.25% per annum.
The Credit Facility requires compliance with a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio, each as defined in the Credit Facility. In addition, at our option, we may choose to increase the maximum consolidated leverage ratio for a certain period following a significant acquisition, subject to certain limitations, as defined in the Credit Facility. As of June 30, 2026, we were in compliance with required ratios.
The Credit Facility contains various customary representations, warranties and covenants that, among other things and subject to certain specified circumstances and exceptions, restrict or limit the ability of the Company and its subsidiaries to incur indebtedness (including guarantees), grant liens, make investments, pay dividends or distributions with respect to capital stock or make other restricted payments, make prepayments on other indebtedness, engage in mergers or other fundamental changes, dispose of property, or change the nature of their business.
The Credit Facility includes various events of default (subject to certain materiality thresholds and/or grace periods), including non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations or warranties, cross-default to other material indebtedness, bankruptcy and insolvency events, invalidity or impairment of guarantees or security interests or invalidity of loan documents, certain ERISA events, unsatisfied or unstayed judgments and change of control.
Other Financing Arrangements. We maintain finance leases primarily related to transportation equipment. During the first half of 2026, we entered into $1.5 million of new finance lease liabilities in exchange for leased assets.
In addition, at June 30, 2026, we had $3.7 million in outstanding letters of credit (inclusive of the amount outstanding under the Credit Facility as described above), performance bonds, and other guarantees.
Fair Value of Financial Instruments. Our financial instruments include cash and cash equivalents, receivables, payables, and debt. We believe the carrying values of these instruments approximated their fair values at June 30, 2026 and December 31, 2025. Cash equivalents primarily consist of money market accounts which are measured at fair value on a recurring basis using a market approach based on quoted prices in active markets.

Note 9 – Commitments and Contingencies
In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. In addition, in connection with the Sale Transaction, we have indemnified the Purchaser for certain pre-closing contingencies of the Fluids Systems business. While the outcome of litigation or other proceedings against us, including pre-closing contingencies of the Fluids Systems business, cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements.

Note 11 – Segment Data
We have one reportable segment. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, allocates resources and assesses financial performance on a consolidated basis. The Company’s operations, currently in the United States and United Kingdom, are substantially similar with respect to services provided, type of customers, and sourcing of materials. Resource allocations are based on the capacity of the Company’s existing rental fleet, manufacturing facility and current status of operations, including projected demand for our products and services in the industries and locations we serve. Consolidated income from continuing operations as presented in the consolidated statements of operations is used to measure performance. As such, management has determined that the Company functions as a single operating segment, and reports as a single reportable segment.

ITEM 2.    Managements Discussion and Analysis of Financial Condition and Results of Operations
The following discussion of our financial condition, results of operations, liquidity, and capital resources should be read in conjunction with the unaudited condensed consolidated financial statements and notes thereto included in this report as well as our Annual Report on Form 10-K for the year ended December 31, 2025. Our second quarter represents the three-month period ended June 30 and our first half represents the six-month period ended June 30. Unless otherwise noted, all currency amounts are stated in U.S. dollars. The reference to a “Note” herein refers to the accompanying Notes to Unaudited Condensed Consolidated Financial Statements contained in Item 1 “Financial Statements.”
Overview
NPK International Inc. (“NPK,” the “Company,” “we,” “our,” or “us”) is a worksite access solutions company that manufactures, sells, and rents recyclable composite matting products, along with a full suite of services, including planning, logistics, and site restoration. In the first half of 2026, 67% of our revenues were generated from the rental of our recyclable composite matting systems, along with related site construction and services to customers in various markets including power transmission, oil and natural gas exploration and production, pipeline, renewable energy, petrochemical, construction and other industries within the United States and United Kingdom. The remaining 33% of our first half of 2026 revenues were generated from the sale of our manufactured recyclable composite mats to customers around the world, with power transmission being the primary end-market.
2026 Priorities
Our long-term strategy includes key foundational elements that are intended to enhance long-term shareholder value creation:
Accelerate Organic Growth – We seek to accelerate revenue growth through the expansion of our rental business, which includes a combination of geographic expansion to new growth territories, primarily within the U.S., while also expanding customer market share within currently-served markets. As part of this effort, we have placed a particular emphasis on penetrating larger-scale, longer-term (six months or longer) projects, which we believe will help drive improvements in revenue stability and operational efficiency. Due in part to the success of our efforts, rental and service revenues increased $16 million, or 18%, year-over-year for the first half of 2026, including a 22% increase in rental revenues. We prioritize investment capital to support our organic growth objective, where over the past several years, we have seen the strong market adoption of our specialty rental products and differentiated service offering. During the first half of 2026, we made net investments of $24.3 million in the expansion of our composite rental fleet, expanding our owned composite mat rental fleet by 7%. Further, with our revenue growth and the favorable macro-environment, in March 2026, our Board of Directors approved management’s plan to expand our composite mat production capacity by approximately 50% over current levels. We expect to invest $40 million to $45 million through the second quarter of 2027 to complete this expansion, of which $4.1 million was invested in the second quarter of 2026, with production expected to start up by mid-2027.
Pursue Inorganic Growth – We seek to accelerate our growth and enhance shareholder value through strategically-aligned inorganic actions, leveraging our scale to increase our value and relevance to customers, and we continually evaluate inorganic opportunities that align with our objectives. In November 2025, we completed the acquisition of Grassform Plant Hire Limited (“Grassform”), a U.K. market leader in ground protection and temporary roadway solutions and services with a fleet of over 20,000 composite mats. Our U.K. operations generated $19.2 million of revenues during the first half of 2026, a $10.2 million increase over the first half of 2025, with the substantial majority of the increase driven by the Grassform acquisition.
Drive Operational Efficiency – We are focused on efficiency improvements and operating cost optimization across every aspect of our business. Throughout 2025, we continued to evaluate and execute actions intended to streamline the organization and our cost structure, driving improvements in profitability. SG&A as a percentage of revenues was 17.5% for the first half of 2026 compared to 19.1% for the first half of 2025.
Enhance Return on Capital – We are committed to maintaining a strong balance sheet, prioritizing organic investment to expand our rental business while evaluating accretive inorganic growth opportunities to accelerate growth and returning excess cash generation via programmatic share repurchases. During the first half of 2026, we utilized $2.7 million to repurchase 0.2 million shares under our share repurchase program.

Selling, general and administrative expenses as a percentage of revenues was 17.4% for the second quarter of 2026 compared to 20.0% for the second quarter of 2025. In May 2026, the Compensation Committee modified the retirement eligibility terms applicable to our outstanding long-term incentive awards, including unvested grants from 2024 and 2025, and SG&A for the second quarter of 2026 includes a $0.9 million charge reflecting the acceleration of compensation expense for such awards for retirement eligible executive officers and other employees. The second quarter of 2025 included a $1.2 million charge related to performance-based awards measured on the Company’s total shareholder return (“TSR”) as compared to the TSR of a designated peer group, as well as $0.3 million of severance costs.
Other operating (income) loss, net
Other operating (income) loss, net primarily includes gains and losses on sales of non-rental assets.
Foreign currency exchange
Foreign currency exchange for the second quarter of 2026 and 2025 reflects the impact of currency translation on assets and liabilities (including intercompany balances) that are denominated in currencies other than functional currencies, principally related to our U.K. operations.
Interest (income) expense, net
Interest expense, net was minimal for both the second quarter of 2026 and 2025, reflecting limited outstanding debt.
Provision for income taxes from continuing operations
The provision for income taxes from continuing operations was $3.9 million for the second quarter of 2026, reflecting an effective tax rate of 25%, compared to income taxes of $3.5 million for the second quarter of 2025, reflecting an effective tax rate of 28%.
Income (loss) from discontinued operations, net of tax

Revenues
Revenues increased 18% to $156.7 million for the first half of 2026, compared to $133.0 million for the first half of 2025, including an 18% increase in both rental and service revenues and product sales revenues. Rental revenues increased $13.1 million (22%) primarily due to higher rental volume driven by our organic growth efforts along with the contribution from the Grassform acquisition, as well as modestly higher pricing. Service revenues increased $2.7 million (9%), primarily attributable to the contribution from the Grassform acquisition. Product sales revenues increased $7.8 million (18%), reflecting continued strength in customer adoption of manufactured composite matting products relative to timber-based products that represent the primary solution used for worksite access in the market. During the first half of 2026, approximately 75% of our product sales revenues were derived from utility companies.
Cost of revenues
Cost of revenues increased 20% to $99.3 million for the first half of 2026 (36.6% gross profit margin), compared to $82.6 million for the first half of 2025 (37.9% gross profit margin), primarily driven by the 18% increase in revenues described above. The decline in gross profit margin is primarily due to modestly lower rental fleet utilization attributable to the timing of large-scale project completions in the first half of 2026, $2.8 million of higher cross-rental costs required to meet customer
17


rental demand, and $0.2 million of expenses associated with our manufacturing expansion effort, partially offset by improved rental pricing and manufacturing cost leverage for product sales.
Selling, general and administrative expenses
Selling, general and administrative expenses increased to $27.4 million for the first half of 2026, which includes $1.3 million attributable to the Grassform acquisition, compared to $25.4 million for the first half of 2025. Selling, general and administrative expenses as a percentage of revenues was 17.5% for the first half of 2026 compared to 19.1% for the first half of 2025. The first half of 2026 includes a $0.9 million charge reflecting the acceleration of stock-based compensation expense for retirement eligible executive officers and other employees. The first half of 2025 included a $1.2 million charge related to performance-based awards measured on the Company’s TSR as compared to the TSR of a designated peer group, as well as $0.4 million of severance costs.
Other operating (income) loss, net
Other operating (income) loss, net primarily includes gains and losses on sales of non-rental assets.
Foreign currency exchange
Foreign currency exchange for the first half of 2026 and 2025 reflects the impact of currency translation on assets and liabilities (including intercompany balances) that are denominated in currencies other than functional currencies, principally related to our U.K. operations.
Interest (income) expense, net
Interest expense, net was minimal for both the first half of 2026 and 2025, reflecting limited outstanding debt.
Provision for income taxes from continuing operations
The provision for income taxes from continuing operations was $7.5 million for the first half of 2026, reflecting an effective tax rate of 25%, compared to income taxes of $7.0 million for the first half of 2025, reflecting an effective tax rate of 27%.
Income (loss) from discontinued operations, net of tax
Income (loss) from discontinued operations, net of tax reflects net costs related to the former Fluids Systems segment, which was sold in the third quarter of 2024. In the first half of 2026, we recognized a $0.5 million pre-tax gain on sale related to the resolution of certain contractual indemnifications related to the Sale Transaction, which was partially offset by costs associated with the transaction as well as the closure of certain foreign subsidiaries that are no longer operational.

Liquidity and Capital Resources
Net cash provided by operating activities was $43.0 million for the first half of 2026 compared to $30.3 million for the first half of 2025. Net income adjusted for non-cash items provided cash of $47.9 million in the first half of 2026, compared to $38.2 million in 2025, while changes in working capital used cash of $4.9 million in the first half of 2026, compared to $7.9 million of cash used in 2025.
Net cash used in investing activities was $26.7 million for the first half of 2026, which includes $33.2 million in capital expenditures partially offset by $5.5 million in additional proceeds from the sale of the Fluids Systems business. The substantial majority of our capital expenditures for the first half of 2026 and 2025 were directed to expanding our mat rental fleet, and 2026 includes $4.1 million spent on the expansion of our Carencro, Louisiana manufacturing operations. Net cash used in investing activities was $0.8 million for the first half of 2025, which includes $21.7 million in capital expenditures partially offset by $14.5 million in additional proceeds from the sale of the Fluids Systems business and $3.3 million in proceeds from the sale of assets.
Net cash used in financing activities was $13.1 million for the first half of 2026, which primarily reflects net repayments on our Credit Facility and other existing financing arrangements as well as $2.7 million in share purchases under our repurchase program. Net cash used in financing activities was $21.8 million for the first half of 2025.
We primarily manage our liquidity utilizing cash on hand and availability under our Credit Facility and other existing financing arrangements.
We expect future working capital requirements for our operations will generally fluctuate directionally with revenues, and we expect net capital expenditures in 2026 to be $65 million to $80 million, which includes $35 million to $45 million in the expansion of our rental fleet and $20 million to $25 million for the manufacturing expansion project. Our planned capital expenditures for 2026 were reduced in the second quarter of 2026, primarily reflecting changes in the timing of manufacturing expansion expenditures which will not impact our anticipated mid-year 2027 completion date. We also expect to use a portion of our existing liquidity to pursue inorganic growth opportunities and return value to our shareholders through share repurchases. We expect cash on hand and cash generated by operations, as well as the projected availability under our Credit Facility and other existing financing arrangements, to be adequate to fund our current operations during the next 12 months.

Credit Facility. In June 2025, we entered into a U.S. senior secured revolving credit agreement (the “Credit Facility”) with a group of lenders that provides financing of up to $150 million available for borrowings (inclusive of letters of credit), which can be increased up to $250 million, subject to certain conditions. The Credit Facility and the loans made under the Credit Facility are secured by a first priority lien on substantially all of the personal property of the Company and its significant U.S. subsidiaries as guarantors (subject to customary exceptions and exclusions). The Credit Facility will mature in June 2030.
As of June 30, 2026, we had no outstanding borrowings and $1.9 million in outstanding letters of credit, resulting in $148.1 million of remaining availability under the Credit Facility.
Under the terms of the Credit Facility, we may elect to borrow at a variable interest rate based on either the Term SOFR rate or an alternate base rate plus, in each case, a per annum applicable margin. The applicable margin will range from 1.75% to 2.25% for Term SOFR loans and 0.75% to 1.25% for alternate base rate loans, based on the consolidated leverage ratio (as defined in the Credit Facility) as of the last day of the most recent fiscal quarter. We are also required to pay a commitment fee on the unused portion of the Credit Facility ranging from 0.25% to 0.35% per annum based on the consolidated leverage ratio.
19


As of June 30, 2026, the applicable margin for loans under the Credit Facility was 1.75% for Term SOFR loans and 0.75% for alternate base rate loans, and the applicable commitment fee was 0.25% per annum.
The Credit Facility requires compliance with a maximum consolidated leverage ratio and a minimum consolidated fixed charge coverage ratio, each as defined in the Credit Facility. In addition, at our option, we may choose to increase the maximum consolidated leverage ratio for a certain period following a significant acquisition, subject to certain limitations, as defined in the Credit Facility. As of June 30, 2026, we were in compliance with required ratios.
The Credit Facility contains various customary representations, warranties and covenants that, among other things and subject to certain specified circumstances and exceptions, restrict or limit the ability of the Company and its subsidiaries to incur indebtedness (including guarantees), grant liens, make investments, pay dividends or distributions with respect to capital stock or make other restricted payments, make prepayments on other indebtedness, engage in mergers or other fundamental changes, dispose of property, or change the nature of their business.
The Credit Facility includes various events of default (subject to certain materiality thresholds and/or grace periods), including non-payment of principal, interest or fees, violation of covenants, inaccuracy of representations or warranties, cross-default to other material indebtedness, bankruptcy and insolvency events, invalidity or impairment of guarantees or security interests or invalidity of loan documents, certain ERISA events, unsatisfied or unstayed judgments and change of control.
Other Financing Arrangements. We maintain finance leases primarily related to transportation equipment. During the first half of 2026, we entered into $1.5 million of new finance lease liabilities in exchange for leased assets.
In addition, at June 30, 2026, we had $3.7 million in outstanding letters of credit (inclusive of the amount outstanding under the Credit Facility as described above), performance bonds, and other guarantees.
Critical Accounting Estimates and Policies
Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), which requires management to make estimates and assumptions that affect the reported amounts and disclosures. Significant estimates used in preparing our consolidated financial statements include estimated cash flows and fair values used for impairments of long-lived assets, including goodwill and other intangibles, and valuation allowances for deferred tax assets. Our estimates are based on historical experience and on our future expectations that we believe to be reasonable. The combination of these factors forms the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from our current estimates and those differences may be material.
For additional discussion of our critical accounting estimates and policies, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2025. Our critical accounting estimates and policies have not materially changed since December 31, 2025.

ITEM 3.    Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risk from changes in interest rates and changes in foreign currency exchange rates. A discussion of our primary market risk exposure in financial instruments is presented below.
Interest Rate Risk
We are primarily exposed to interest rate risk through our Credit Facility, which is subject to variable interest rates as determined by the debt agreement. At June 30, 2026, we had no borrowings under our Credit Facility.
Foreign Currency Risk
Our principal foreign operations are currently conducted in the U.K., which contributed approximately 12% of our consolidated revenues for the first half of 2026. We have foreign currency exchange risks associated with these operations, which are conducted principally in British pounds. Historically, we have not used off-balance sheet financial hedging instruments to manage foreign currency risks when we enter into a transaction denominated in a currency other than our local currencies.
ITEM 4.    Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) as of the end of the period covered by this quarterly report in accordance with Rules 13a-15 and 15d-15 under the Exchange Act. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of June 30, 2026, the end of the period covered by this quarterly report.
Changes in Internal Control Over Financial Reporting
There were no changes in internal control over financial reporting during the quarter ended June 30, 2026 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II         OTHER INFORMATION
ITEM 1.    Legal Proceedings
In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. In addition, in connection with the Sale Transaction, we have indemnified the Purchaser for certain pre-closing contingencies of the Fluids Systems business. While the outcome of litigation or other proceedings against us, including pre-closing contingencies of the Fluids Systems business, cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements.
ITEM 1A.    Risk Factors
There have been no material changes during the period ended June 30, 2026 to our “Risk Factors” as discussed in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2025.

Our Board of Directors has authorized a securities repurchase program available for repurchases of our common stock. In April 2025, our Board of Directors increased the remaining authorization under the repurchase program to $100 million.
Our repurchase program authorizes us to purchase outstanding shares of our common stock in the open market or as otherwise determined by management, subject to certain limitations under the Credit Facility (as defined in Note 8) and other factors. The repurchase program has no specific term. Repurchases are expected to be funded from operating cash flows, available cash on hand, and borrowings under our Credit Facility. As part of the share repurchase program, our management has been authorized to establish trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934. All shares purchased are held as treasury stock.
There were no shares of common stock repurchased under the repurchase program during the three months ended June 30, 2026. As of June 30, 2026, we had $89.0 million remaining under the program.
In addition, during the three months ended June 30, 2026, we purchased an aggregate of 223,731 shares surrendered in lieu of taxes under vesting of restricted shares.
