3 Safe Harbor DISCLAIMERS Forward Looking Statements This presentation contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended. All statements other than statements of historical facts are forward-looking statements. Words such as “will,” “may,” “could,” “would,” “should,” “anticipates,” “believes,” “estimates,” “expects,” “plans,” “intends,” “guidance,” and similar expressions are intended to identify these forward-looking statements but are not the exclusive means of identifying them. These statements are not guarantees that our expectations will prove to be correct and involve a number of risks, uncertainties, and assumptions. Many factors, including those discussed more fully elsewhere in this release and in documents filed with the Securities and Exchange Commission by NPK, particularly its Annual Report on Form 10-K, and its Quarterly Reports on Form 10-Q, as well as others, could cause actual plans or results to differ materially from those expressed in, or implied by, these statements. These risk factors include, but are not limited to, risks related to our recently completed sale of the Fluids Systems business; our ability to generate organic growth; economic and market conditions that may impact our customers’ future spending; the effective management of our fleet, including our ability to properly manufacture, safeguard, and maintain our fleet; international operations; operating hazards present in our and our customers’ industries and substantial liability claims; our contracts that can be terminated or downsized by our customers without penalty; our product offering and market expansion; our ability to attract, retain, and develop qualified leaders, key employees, and skilled personnel; expanding our services in the utilities sector, which may require unionized labor; the price and availability of raw materials; inflation; capital investments and business acquisitions; market competition; technological developments and intellectual property; severe weather, natural disasters, and seasonality; public health crises, epidemics, and pandemics; our cost and continued availability of borrowed funds, including noncompliance with debt covenants; environmental laws and regulations; legal compliance; the inherent limitations of insurance coverage; income taxes; cybersecurity incidents or business system disruptions; activist stockholders that may attempt to effect changes at our Company or acquire control over our Company; share repurchases; and our amended and restated bylaws, which could limit our stockholders’ ability to obtain what such stockholders believe to be a favorable judicial forum for disputes with us or our directors, officers or other employees. We assume no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by securities laws. NPK's filings with the Securities and Exchange Commission can be obtained at no charge at www.sec.gov, as well as through our website at www.npki.com. Non-GAAP Financial Measures This presentation includes references to financial measurements that are supplemental to the Company’s financial performance as calculated in accordance with generally accepted accounting principles (“GAAP”). These non-GAAP financial measures include Adjusted Income (Loss) from Continuing Operations, Adjusted Income (Loss) from Continuing Operations Per Common Share, earnings before interest, taxes, depreciation and amortization (“EBITDA”) from Continuing Operations, Adjusted EBITDA from Continuing Operations, Adjusted EBITDA Margin from Continuing Operations, Free Cash Flow, and Net Debt (Cash). We believe these non-GAAP financial measures are frequently used by investors, securities analysts and other parties in the evaluation of our performance and liquidity with that of other companies in our industry. Management uses these measures to evaluate our operating performance, liquidity and capital structure. In addition, our incentive compensation plan measures performance based on our consolidated EBITDA, along with other factors. The methods we use to produce these non-GAAP financial measures may differ from methods used by other companies. These measures should be considered in addition to, not as a substitute for, financial measures prepared in accordance with GAAP.

Strong balance sheet provides optionality As of 1Q25, $13 million of net cash* on-hand, which provides optionality to execute disciplined growth strategy, balancing organic investment in rental fleet expansion, the pursuit of strategically-aligned inorganic actions, and robust return of capital. * Represents a non-GAAP financial measure.
