MANAGEMENT COMMENTARY

"We are pleased with the strong financial results for the second quarter of 2026, reflecting consistent execution by our team members across the organization, continued momentum in our core power transmission markets, and efficient margin realization," stated Matthew Lanigan, President and CEO of NPK International. "During the second quarter, we successfully navigated the demobilization of several large-scale projects and delivered 20% year-over-year revenue growth, highlighted by another quarter of record rental revenue and robust demand for product sales, while adjusted EBITDA grew 37%. Supported by sustained market strength and an ongoing focus on operational excellence, we are well positioned for continued strength in the second half of 2026 and have raised our full year earnings guidance.

Lanigan continued, "We have continued to make important progress on our strategic initiatives, as evidenced by our strong operating momentum. Notably, we have advanced our Carencro, Louisiana manufacturing expansion effort, which remains on track to start up by mid-2027, expanding capacity by approximately 50%. During the second quarter, we invested more than $4 million of the expected $40 million to $45 million required to complete the project, and we are confident that this expansion and our continuing debottlenecking initiatives will both enhance margins through reduced usage of cross-rental mats while also supporting our longer-term growth objectives.

"Our capital allocation strategy continues to prioritize investments in the growth of our rental fleet and our manufacturing capacity expansion to support sustained organic growth, strategic acquisitions, and the return of capital through our disciplined share repurchase program. With minimal net debt and nearly $150 million of availability under our bank facility, we are well positioned to pursue our strategic growth and capital allocation priorities.

"The outlook for utility transmission spending remains robust, driven by projected load growth, an aging infrastructure, and the need to connect new capacity to the grid. While timing of large projects is difficult to predict, we remain confident in the near-term outlook and our ability to continue generating double-digit rental growth in the coming years. We continue to be encouraged by the opportunities ahead and remain confident in our ability to execute on our strategic priorities and create durable 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.

Second quarter 2026 highlights include:

Strong customer demand for matting rental and related services. Revenues from specialty rental and related services increased to $54 million in the second quarter of 2026, with record rental revenues driven by strong demand from key customer accounts in support of power transmission projects and the impact of our recent acquisition. Revenues from product sales were $28 million for the second quarter of 2026, our highest quarterly level in two years, 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 second quarter of 2026, NPK’s Adjusted EBITDA Margin was 31.5%, a 400 basis improvement from the prior year period, and SG&A as a percentage of revenue was 17.4%, a 260 basis point improvement versus the prior year period. In May 2026, the Compensation Committee of our Board of Directors modified the retirement eligibility terms applicable to our long-term incentive awards, including unvested grants from 2024 and 2025. As a result, 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.
Manufacturing efficiency and capacity expansion. NPK continues to execute on its recently approved plans to expand our Carencro, Louisiana manufacturing capacity by approximately 50% from current levels. The Company expects to invest $40 million to $45 million by mid-2027, including $4.1 million invested in the second quarter, with additional production expected to start up by mid-2027.

FINANCIAL PERFORMANCE

In the second quarter of 2026, NPK generated revenue of $81.6 million, an increase of 20%, compared to $68.2 million in the prior year period. Rental and service revenue increased 16% to $53.6 million, while product sales increased 28% to $28.0 million.

Gross margin was 37.0% in the second quarter of 2026, compared to 36.9% in the prior year period.

Selling, general and administrative expenses were $14.2 million (17.4% of revenues) in the second quarter of 2026, compared to $13.7 million (20.0% of revenues) in the second quarter of 2025. SG&A for the second quarter of 2026 includes a $0.9 million charge related to acceleration of long-term incentive compensation expense due to the modification of our retirement eligibility terms.

NPK generated income from continuing operations of $12.0 million, or $0.14 per diluted share, compared to $8.8 million, or $0.10 per diluted share, in the second quarter of 2025. Second quarter 2026 adjusted income from continuing operations was $12.8 million, or $0.15 per diluted share.

The Company reported Adjusted EBITDA from Continuing Operations of $25.7 million in the second quarter of 2026, or 31.5% of total revenue, compared to $18.8 million, or 27.5% of total revenue, in the prior year period.

BALANCE SHEET AND LIQUIDITY

As of June 30, 2026, NPK had total cash of $8.4 million, total debt of $10.6 million, and available liquidity under its senior secured revolving credit facility of $148 million.

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.

Adjusted Income from Continuing Operations and Adjusted Income from Continuing Operations Per Common Share

The following tables reconcile the Company’s income from continuing operations and income from continuing operations per common share calculated in accordance with GAAP to the non-GAAP financial measures of Adjusted Net Income from Continuing Operations and Adjusted Net Income from Continuing Operations Per Common Share:
