10-Q
Rhea-AI Filing Summary
NPK International Inc. reported higher first-quarter 2026 results, with revenue rising to $75.1 million from $64.8 million a year earlier as demand for its rental composite matting solutions grew. Rental and service revenues increased 20%, helped by larger, longer-term projects and the Grassform acquisition in the U.K.
Net income edged up to $10.5 million, and diluted earnings per share were $0.12, roughly flat versus 2025 as gross margin compressed to 36.2% from 39.0% due to cross-rental costs and manufacturing expansion expenses. Operating cash flow strengthened to $21.1 million, funding $16.7 million of capital spending, mainly to expand the rental fleet.
The company ended the quarter with $6.5 million of cash, total debt of $10.6 million, and no borrowings under its $150 million revolving Credit Facility. Management plans $75–$90 million of 2026 net capital expenditures, including a roughly 50% expansion of composite mat manufacturing capacity and continued fleet growth, while also repurchasing 0.2 million shares for $2.7 million.

Insights
Solid top-line growth, flat EPS and heavy reinvestment define NPKI’s quarter.
NPK International delivered first-quarter 2026 revenue of $75.1 million, up 16% year over year, driven mainly by a 27% increase in rental revenue and contributions from the Grassform acquisition in the U.K. Product sales also grew 8%, reflecting continued adoption of composite mats over timber alternatives.
Profitability was more muted. Gross margin declined to 36.2% from 39.0%, pressured by about $3.5 million of cross-rental costs, slightly lower fleet utilization, and upfront costs tied to a major manufacturing expansion. Net income was $10.5 million, only modestly above last year, with diluted EPS at $0.12.
Cash generation improved, with operating cash flow of $21.1 million funding $16.7 million of capex and $2.7 million of share repurchases. The balance sheet remains conservative: total debt is $10.6 million and there are no borrowings on the $150 million Credit Facility, leaving $148.1 million of availability as of March 31, 2026. Management plans significant additional spending—$75–$90 million of 2026 net capex, including a roughly 50% increase in mat manufacturing capacity—which could support future growth but keeps capital intensity elevated.

5 terms
temporary worksite access solutions financial
"NPK International Inc. is a temporary worksite access solutions company that manufactures, sells, and rents recyclable composite matting products"
composite matting products financial
"manufactures, sells, and rents recyclable composite matting products, along with a full suite of services"
Credit Facility financial
"In June 2025, 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.
Rule 10b5-1 trading plan regulatory
"adopted a Rule 10b5-1 trading plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c)"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
ERP implementation technical
"We are currently undertaking a significant ERP implementation to upgrade our information technology platforms and business processes"
ERP implementation is the process of installing and configuring an enterprise resource planning (ERP) software system that combines a company’s core functions—like accounting, inventory, sales and HR—into one central platform. For investors, it matters because the rollout can change costs, efficiency and risk: a smooth implementation can boost productivity and margins, while problems can disrupt operations, delay revenue and increase expenses. Think of it as replacing many kitchen appliances with a single smart appliance that must be set up correctly to work well.

NPK INTERNATIONAL INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
Note 1 – Basis of Presentation and Significant Accounting Policies
NPK International Inc. is a temporary 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 and our first quarter represents the three-month period ended March 31. The results of operations for the first quarter 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 March 31, 2026 and our results of operations and cash flows for the first quarter 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.

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 employee compensation and depreciation. 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 $49.5 million, as reduced by $0.7 million during the first quarter of 2026, or $45.3 million net of cash acquired, with $42.1 million funded at closing in 2025 with cash on hand and borrowings under the Credit Facility. 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, 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 $27.8 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 first quarter of 2026 includes $1.5 million 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 March 31, 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 and $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 2026, as well as an $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 quarter 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 7) 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 quarter 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 quarter of 2025, we repurchased an aggregate of 1.8 million shares of our common stock under the repurchase program for a cost of $10.8 million.

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 March 31, 2026, we had no outstanding borrowings and $1.9 million in outstanding letters of credit, resulting in remaining availability of $148.1 million.
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 March 31, 2026, the applicable margin for borrowings 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 March 31, 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 quarter of 2026, we entered into $0.5 million of new finance lease liabilities in exchange for leased assets.
In addition, at March 31, 2026, we had $6.7 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 March 31, 2026 and December 31, 2025.
Note 8 – 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
11
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 10 – 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. Management’s 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 first quarter represents the three-month period ended March 31. 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 temporary 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 quarter of 2026, 69% 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 31% of our first quarter 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 $9 million, or 20%, year-over-year for the first quarter of 2026, including a 27% 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 quarter of 2026, we made net investments of $14.6 million in the expansion of our composite rental fleet, expanding our owned composite mat rental fleet by 4% in the quarter. Further, with our revenue growth and the favorable macro-environment, we have also accelerated our manufacturing capacity expansion planning efforts. 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 over the next five quarters to complete this expansion, with the additional capacity expected to come online 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 $9.2 million of revenues during the first quarter of 2026, a $5.1 million increase over the first quarter 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 17.6% for the first quarter of 2026 compared to 18.1% for the first quarter 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 quarter of 2026, we utilized $2.7 million to repurchase 0.2 million shares under our share repurchase program.

Revenues
Revenues increased 16% to $75.1 million for the first quarter of 2026, compared to $64.8 million for the first quarter of 2025, including a 20% increase in rental and service revenues and an 8% increase in product sales revenues. Rental revenues increased $7.5 million (27%), 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 $1.0 million (7%), primarily attributable to the increased level of customer rental projects, though at a lower rate than rental revenues, due primarily to the higher mix of larger-scale, longer term rental projects. Product sales revenues increased $1.7 million (8%), reflecting continued strength in customer adoption of manufactured composite matting products relative to timber-based products that represent the primary solution used for temporary worksite access in the market. During the first quarter of 2026, nearly 80% of our product sales revenues were derived from utility companies.
Cost of revenues
Cost of revenues increased 21% to $47.9 million for the first quarter of 2026 (36.2% gross profit margin), compared to $39.5 million for the first quarter of 2025 (39.0% gross profit margin), primarily driven by the 16% increase in revenues described above. The decline in gross profit margin is primarily attributable to the impact of approximately $3.5 million of cross-rental costs required to meet customer rental demand, modestly lower rental fleet utilization attributable to the timing of
15
large-scale projects, and 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 $13.2 million for the first quarter of 2026, which includes $0.7 million attributable to the Grassform acquisition, compared to $11.7 million for the first quarter of 2025. Selling, general and administrative expenses as a percentage of revenues was 17.6% for the first quarter of 2026 compared to 18.1% for the first quarter of 2025.
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 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 the first quarter of 2026 and 2025.
Provision for income taxes from continuing operations
The provision for income taxes from continuing operations was $3.6 million for the first quarter of 2026, reflecting an effective tax rate of 26%, compared to $3.5 million for the first quarter of 2025, reflecting an effective tax rate of 25%.
Income (loss) from discontinued operations, net of tax
Income (loss) from discontinued operations, net of tax reflects the former Fluids Systems segment, which was sold in the third quarter of 2024. In the first quarter 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 related to the closure of certain foreign subsidiaries that are no longer operational.
16
Liquidity and Capital Resources
Net cash provided by operating activities was $21.1 million for the first quarter of 2026 compared to $8.8 million for the first quarter of 2025. Net income adjusted for non-cash items provided cash of $22.5 million in the first quarter of 2026, compared to $19.2 million in 2025, while changes in working capital used cash of $1.4 million in first quarter of 2026, compared to $10.3 million in 2025.
Net cash used in investing activities was $10.7 million for the first quarter of 2026, which includes $16.7 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 quarter of 2026 and 2025 were directed to expanding our mat rental fleet. Net cash provided by investing activities was $5.4 million for the first quarter of 2025, which includes $10.7 million in additional proceeds from the sale of the Fluids Systems business partially offset by $10.0 million in capital expenditures.
Net cash used in financing activities was $8.9 million for the first quarter 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 $11.7 million for the first quarter 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 $75 million to $90 million, which includes $35 million to $45 million in the expansion of our rental fleet and $30 million to $35 million for the manufacturing expansion project. 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 March 31, 2026, we had no outstanding borrowings and $1.9 million in outstanding letters of credit, resulting in remaining availability of $148.1 million.
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 March 31, 2026, the applicable margin for borrowings 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 March 31, 2026, we were in compliance with required ratios.
17
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 quarter of 2026, we entered into $0.5 million of new finance lease liabilities in exchange for leased assets.
In addition, at March 31, 2026, we had $6.7 million in outstanding letters of credit (inclusive of the amount outstanding under the Credit Facility as described above), performance bonds, and other guarantees.
18
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 March 31, 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 quarter 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 March 31, 2026, the end of the period covered by this quarterly report.
Changes in Internal Control Over Financial Reporting
We are currently undertaking a significant ERP implementation to upgrade our information technology platforms and business processes. The implementation is occurring in phases, and during the first quarter of 2026, we implemented various modules and functionality, impacting the majority of our operations within the United States.
As a result of this implementation, we have certain changes to our processes and procedures, which, in turn, will result in changes to our internal control over financial reporting. This implementation was subject to various testing and review procedures prior to execution. We believe that the conversion to and implementation of this new system will further strengthen our existing internal control over financial reporting by enhancing certain business processes.
Other than the changes described above, there were no changes in our internal control over financial reporting that occurred during the quarter ended March 31, 2026 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
20
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 March 31, 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.

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.
During the first quarter 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. As of March 31, 2026, we had $89.0 million of authorization remaining under the program.
