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 previously operated a Fluids Systems business which was exited upon the sale of the business in September 2024 (as further described below).

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, 2024. Our fiscal year end is December 31, our third quarter represents the three-month period ended September 30, and our first nine months represents the nine-month period ended September 30. The results of operations for the third quarter and first nine months of 2025 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 September 30, 2025, our results of operations for the third quarter and first nine months of 2025 and 2024, and our cash flows for the first nine months of 2025 and 2024. All adjustments are of a normal recurring nature. Our balance sheet at December 31, 2024 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, 2024.

Our business provides temporary worksite access solutions, including 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. We also sell our manufactured recyclable composite mats to customers around the world, with power transmission being the primary end market.

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 primarily in Europe, the Middle East and Africa, and North America, as well as certain countries in Asia Pacific. On September 13, 2024, we completed the sale of substantially all of the Company’s Fluids Systems segment (the “Sale Transaction”) to SCF Partners (the “Purchaser”). The results of operations of Fluids Systems are reported in discontinued operations in the consolidated statements of operations. All results and information in the consolidated financial statements and related notes are presented for our continuing operations and exclude Fluids Systems unless otherwise noted specifically as discontinued operations. See Note 2 for additional information.

New Accounting Pronouncements

Standards Not Yet Adopted

Income Taxes: Improvements to Income Tax Disclosures. In December 2023, the FASB issued new guidance intended to enhance the transparency and decision usefulness of income tax disclosures. This guidance is effective for us for the year ending December 31, 2025. These requirements are not expected to have an impact on our consolidated financial statements but will impact our income tax disclosures.

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 –Discontinued Operations

Sale of Fluids Systems Business

As discussed above in Note 1 and more fully described in Note 2 in our Annual Report on Form 10-K for the year ended December 31, 2024, on September 13, 2024, we completed the Sale Transaction. In connection with the Sale Transaction in the third quarter of 2024, we received $48.5 million in cash proceeds, net of cash disposed, and recognized a pre-tax loss on sale of $195.7 million, which included a $59.5 million non-cash charge for the reclassification of cumulative foreign currency translation losses related to the Fluids Systems business.

As of September 30, 2025 and December 31, 2024, approximately $3.6 million and $18.0 million, respectively, of net assets were included in the consolidated balance sheets, reflecting receivables and deferred consideration due from the Purchaser net of estimated liabilities due to the Purchaser.

Net assets related to the Sale Transaction consisted of the following:

Receivables due from the Purchaser primarily reflects additional consideration for the actual working capital delivered at closing, of which $15.6 million was received in the first half of 2025. Estimated deferred consideration due from the Purchaser reflects certain pre-closing tax assets and other receivables that are expected to be substantially realized in the fourth quarter of 2025. The note receivable due from the Purchaser matures in March 2030 and bears interest at a rate of 12.5% per year. The receivables and deferred consideration due from the Purchaser are included in other receivables and the note receivable due from the Purchaser is included in other noncurrent assets in the consolidated balance sheet.

Estimated liabilities due to the Purchaser includes certain payables for pre-closing tax liabilities and obligations attributable to the Fluids Systems business that are expected to be substantially settled in 2025, as well as an 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 consolidated balance sheet.

Our estimates for the fair value of deferred consideration due from the Purchaser and liabilities due to the Purchaser may change and any income or expense associated with such changes will be presented in discontinued operations.

The criteria for discontinued operations presentation were met during the third quarter of 2024, and consequently, the results of the former Fluids Systems segment are reported as income (loss) from discontinued operations within the consolidated statements of operations for all periods presented. We elected not to adjust the consolidated statements of cash flows to separately present cash flows attributable to discontinued operations. Accordingly, we have disclosed the depreciation, capital expenditures and significant operating and investing non-cash items related to discontinued operations below.

The following table summarizes the significant items included in income (loss) from discontinued operations in the condensed consolidated statements of operations.

For the first nine months of 2025 and 2024, significant operating and investing items related to the former Fluids Systems segment were as follows:

Note 3 –Earnings Per Share

The following table presents the reconciliation of the numerator and denominator for calculating net income (loss) per share:

We excluded the following weighted-average potential shares from the calculations of diluted net income (loss) per share during the applicable periods because their inclusion would have been anti-dilutive for continuing operations:

Note 4 –Repurchase Program

Our Board of Directors has authorized a securities repurchase program available for repurchases of our common stock. On April 30, 2025, our Board of Directors increased the remaining authorization under the repurchase program to $100.0 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 and available cash on hand. 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 nine months of 2025, we repurchased an aggregate of 3.0 million shares of our common stock under the repurchase program for a cost of $20.4 million. Due to restrictions associated with the Fluids Systems sale process and other events, no shares of common stock were repurchased under the repurchase program during the first nine months of 2024.

As of September 30, 2025, we had $91.7 million remaining under the program.

Note 5 –Stock-Based and Other Long-Term Incentive Compensation

During the second quarter of 2025, 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 0.6 million restricted stock units, which will vest in equal installments over athree-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 $8.45 per share for the restricted stock units and $8.28 per share for the restricted stock awards. At September 30, 2025,3.0 million shares remained available for award under the 2015 Plan and 0.3 million shares remained available for awards under the 2014 Director Plan.

Also, during the second quarter of 2025, the Compensation Committee approved the issuance of 0.4 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 athree-year performance period. TSR performance for the 2025 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, 2028, adjusted for dividends, as compared to the 30-calendar day period ending June 1, 2025. RONCE performance for the 2025 grants will be determined based on the Company’s average three-year RONCE performance for the fiscal years ending December 31, 2025, 2026 and 2027.

The TSR portion of the performance-based restricted stock units had a grant-date fair value of $11.57 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 4.0%, an expected life of 3 years, and an expected volatility of 49.8%. The RONCE portion of the performance-based restricted stock units had a grant-date fair value of $8.45 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.

Note 6 –Receivables

Receivables consisted of the following:

Other receivables as of September 30, 2025 and December 31, 2024 included $4.1 million and $23.2 million, respectively, for amounts due from the Purchaser, including the receivables and estimated deferred consideration related to the Sale Transaction (see Note 2) as well as amounts due under the transition services agreement. Other receivables as of September 30, 2025 and December 31, 2024 also included an insurance receivable of $0.3 million and $1.7 million related to a cybersecurity event.

Changes in our allowance for credit losses were as follows:

Note 7 –Inventories

Inventories consisted of the following:

Raw materials consist primarily of resins and other materials used to manufacture composite mats, as well as materials that are consumed in providing spill containment and other services to our customers. Finished goods consist primarily of our composite mats.

Note 8 –Financing Arrangements and Fair Value of Financial Instruments

Financing arrangements consisted of the following:

Credit Facility. On June 20, 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 on June 20, 2030. The Credit Facility replaced the Amended ABL Facility (as defined below).

As of September 30, 2025, we hadno outstanding borrowings and $5.7 million in outstanding letters of credit, resulting in $144.3 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 September 30, 2025, 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 September 30, 2025, 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.

Asset-Based Loan Facility. Our U.S. asset-based revolving credit agreement, as amended and restated in September 2024 (the “Amended ABL Facility”) provided financing of up to $100 million available for borrowings (inclusive of letters of credit), with a term expiring May 2027. We terminated the Amended ABL Facility in June 2025 and replaced it with the Credit Facility, as described above. As of the date of termination, we hadno outstanding borrowings under the Amended ABL Facility. In the second quarter of 2025, we recognized a charge of $0.2 million in interest expense for the write-off of debt issuance costs in connection with the termination of the Amended ABL Facility.

Other Financing Arrangements. We also maintain finance leases primarily related to transportation equipment. During the first nine months of 2025, we entered into $4.4 million of new finance lease liabilities in exchange for leased assets.

In addition, at September 30, 2025, we had $9.5 million in outstanding letters of credit (inclusive of the amount outstanding under the Credit Facility as described above), performance bonds, and other guarantees.

Interest income, net of $94 thousand for the first nine months of 2025 includes interest income of $1.5 million, net of interest expense of $1.4 million.

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 September 30, 2025 and December 31, 2024. 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 –Income Taxes

The provision for income taxes from continuing operations was $10.0 million for the first nine months of 2025, reflecting an effective tax rate of 28%, compared to a benefit for income taxes from continuing operations of $9.6 million for the first nine months of 2024. The third quarter of 2024 included a $14.6 million benefit primarily related to the release of valuation allowances on U.S. net operating losses and tax credit carryforwards that are expected to be realized following the sale of the Fluids Systems business.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBB Act”) was signed into law in the U.S., which contains a broad range of tax reform provisions affecting businesses. Based on our preliminary analysis of the legislation, we currently expect the legislation will not have a material impact on our estimated annual effective tax rate and expect the provisions providing accelerated tax deductions for certain capital investments to provide additional cash flow timing benefits which, coupled with our existing U.S. federal net operating loss and other carryforward tax benefits, should limit our cash tax obligations over the next several years.

Note 10 –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 agreed to indemnify 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.

The first nine months of 2024 included a $0.6 million gain related to a legal settlement as well as a $0.1 million gain related to the final insurance settlement associated with Hurricane Ida in August 2021.

Note 11 –Supplemental Disclosures to the Statements of Cash Flows

Supplemental disclosures to the statements of cash flows are presented below:

The amounts above for 2024 include payments for our former Fluids Systems segment, as we elected not to adjust the consolidated statements of cash flows to separately present cash flows attributable to discontinued operations. A substantial majority of cash tax payments in 2024 related to our former Fluids Systems segment’s international operations.

Cash, cash equivalents, and restricted cash in the consolidated statements of cash flows consisted of the following:

Note 12 –Segment Data

Following the sale of the Fluids Systems segment in September 2024, we haveone reportable segment. See Note 2 for financial information for our previously reported Fluids Systems segment, now reported as discontinued operations. The Company’s chief operating decision maker (“CODM”), its Chief Executive Officer, allocates resources and assesses financial performance on a consolidated basis. Consolidated income from continuing operations as presented in the consolidated statements of operations is used to measure performance.

The following table presents further disaggregated revenues by geography, based on the country in which the sale originates:
