Adjusted EBITDA from Continuing Operations financial
"Adjusted EBITDA from Continuing Operations of $22.5 million, +14%"
Free Cash Flow financial
"Free Cash Flow | $ | 4.9 | | $ | 0.6 | | $ | 4.3"
Free cash flow is the amount of money a company has left over after paying all its expenses and investing in its business, like buying equipment or updating facilities. It shows how much cash is available to reward shareholders, pay down debt, or save for future growth. This helps investors understand if a company is financially healthy and able to grow.
non-GAAP financial measures financial
"the Company has supplemented its financial results... with non-GAAP financial measures"
Non-GAAP financial measures are numbers companies use to show their financial performance that exclude certain expenses or income. They help investors see how the company might perform without one-time costs or other unusual items, giving a different perspective from official reports. However, since they can be adjusted, they don’t always tell the full story and should be looked at alongside standard financial figures.
Operating margin from continuing operations financial
"Operating margin from continuing operations (%) | 19.2% | | 20.9%"
forward-looking statements regulatory
"This news release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
trailing twelve months financial
"Trailing Twelve Months (“TTM”)"
Trailing twelve months is a rolling measure of a company’s financial performance that adds together the most recent four quarters of results to show how the business has done over the last 12 months, rather than a fixed fiscal year. Investors use it like checking a car’s last 12 months of fuel use to see current efficiency — it highlights recent trends, evens out seasonal swings, and provides an up-to-date basis for comparing and valuing companies.

Item 2.02     Results of Operations and Financial Condition.
On April 30, 2026, NPK International Inc. (the “Company”) issued a press release announcing financial information for the three months ended March 31, 2026. The press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.
The information in Item 2.02 of this Current Report on Form 8-K and the information in the exhibit attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act except as expressly set forth by specific reference in such filing.
Use of Non-GAAP Financial Information
To help understand the Company’s financial performance, the Company has supplemented its financial results that it provides in accordance with generally accepted accounting principles (“GAAP”) with non-GAAP financial measures. Such 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, and Free Cash Flow.
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. Applicable reconciliations to the nearest GAAP financial measure of each non-GAAP financial measure are included in the attached Exhibit 99.1.

MANAGEMENT COMMENTARY
“We were very pleased with our strong first quarter 2026 results, further building on the sustained momentum we experienced during 2025,” stated Matthew Lanigan, President and CEO of NPK International. “First quarter revenue increased 16% year-over-year, driven by another record quarter of rental and services revenues and strong product demand from utility customers. The environment for power transmission spending remains robust, as evident by our sustained strength in rental fleet utilization, improved pricing, and strong quoting activity.
Lanigan continued, “As we have discussed, while we have made progress in improving our manufacturing throughput, the momentum in utility spending and our confidence in the durability of these trends has caused us to accelerate our planned manufacturing capacity expansion plans. To this end, we are pleased to report that our Board has approved plans to expand manufacturing capacity by approximately 50% from current levels, with the additional capacity expected to be online by mid-2027. We expect to invest $40 million to $45 million to complete the expansion, which we believe represents an attractive investment to support the planned growth in our business.
“Our disciplined financial management enabled us to generate strong cash flow, delivering $21 million of operating cash flow while investing nearly $15 million in fleet expansion during the first quarter. We

continued to execute on our disciplined capital return strategy, utilizing $3 million for share repurchases during the quarter. We have $148 million of availability under our bank facility and minimal net debt, providing us with ample financial flexibility to continue executing our strategic growth objectives.
“First quarter results were in line with our expectations, demonstrating the improved consistency as we grow the business. Based on this strong first quarter performance and our confidence in the business outlook, we are raising our full-year fiscal 2026 guidance. Our scale and ability to execute on the largest and most complex transmission projects has us well positioned to benefit from the favorable secular drivers benefiting our end markets. We remain focused on execution against our strategic priorities, including our commitment to our disciplined allocation framework, all with an ongoing focus on providing value for our shareholders,” concluded Lanigan.
BUSINESS UPDATE
NPK’s business plan is designed to drive organic commercial growth within targeted, higher-margin product and rental markets; improve asset optimization and organizational efficiency; and pursue a capital allocation strategy that prioritizes investments with superior return profiles, together with a programmatic return of capital program.
First quarter 2026 highlights include:
Strong customer demand for matting rental and related services. Revenues from specialty rental and related services increased to $52 million in the first quarter of 2026, with record rental revenues driven by strong sustained demand from key customer accounts in support of power transmission projects and the impact of our recent acquisition. Revenues from product sales were $23 million for the first quarter of 2026, primarily reflecting the continued strong demand from utility companies.
Improved operating efficiency. NPK remains focused on efficiency improvements and operating cost optimization across every aspect of its business. In the first quarter of 2026, NPK’s SG&A as a percentage of revenue was 17.6%, a 60 basis point improvement versus the prior year period.
Return of capital to shareholders. The Company continued to execute on its disciplined return of capital strategy during the first quarter of 2026, using $2.7 million of cash to repurchase 0.2 million of outstanding shares under the repurchase program.
Manufacturing efficiency and capacity expansion. Management announced that the Board of Directors recently approved plans to expand manufacturing capacity by approximately 50% from current levels. The Company expects to invest $40 million to $45 million over the next five quarters to complete this expansion, with the goal of bringing the additional capacity online by mid-2027.

Gross margin was 36.2% in the first quarter of 2026, compared to 39.0% in the prior year period. The decline primarily reflects an elevated level of cross-rental activity, as well as modestly lower fleet utilization as compared to the exceptionally strong performance in the prior-year period.

The Company reported Adjusted EBITDA from Continuing Operations of $22.5 million in the first quarter of 2026, or 29.9% of total revenue, compared to $19.7 million, or 30.4% of total revenue, in the prior year period.

Non-GAAP Reconciliations
(Unaudited)

To help understand the Company’s financial performance, the Company has supplemented its financial results that it provides in accordance with generally accepted accounting principles (“GAAP”) with non-GAAP financial measures. Such financial measures include Adjusted Income from Continuing Operations, Adjusted Income 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, and Free Cash Flow.
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.
