MANAGEMENT COMMENTARY

“We were extremely pleased with our strong fourth quarter performance, which capped a record year and underscored the strength of our long-term strategy and the continued momentum across our key end-markets,” said Matthew Lanigan, President and CEO of NPK International. “Fourth quarter revenue increased 9% sequentially and 31% year over year, driven by sustained strength in rental fleet utilization and continued robust demand for our DURA-BASE products from utility customers. As expected, profitability rebounded meaningfully from the third quarter, with fourth quarter Adjusted EBITDA increasing 41% sequentially and 27% year over year.

Lanigan continued, “Looking at full-year 2025, we made significant progress across each of the strategic priorities we outlined at the start of the year. Our top focus was accelerating organic rental growth, which we believe is our most durable long-term value driver. For the year, rental revenue increased 39%, contributing to total revenue growth of 27%. Importantly, Adjusted EBITDA margin expanded by more than 200 basis points in 2025, reflecting the operating leverage inherent in our model and driving Adjusted EBITDA growth of 38% compared with the prior year.

“A key pillar of our organic growth strategy remains our focus on manufacturing capacity expansion. Production volumes increased more than 15% year-over-year in 2025, and the initiatives implemented during the year are anticipated to provide sufficient production capacity to support our growth needs in 2026. Looking longer-term, our team is wrapping up the evaluation of manufacturing expansion alternatives. We are very encouraged by the team’s progress and expect to finalize our investment details and timelines within the next few months, with an expectation of bringing additional production capacity online in the first half of 2027.

“As part of our disciplined capital allocation strategy, an important priority coming into 2025 was the focused pursuit of core inorganic growth. We were pleased to complete the acquisition of Grassform Plant Hire Limited in November, which strengthens our capabilities and enhances our scale as a top tier worksite access provider in the U.K. market. We ended the year in a strong financial position and remain committed to our balanced capital allocation framework that prioritizes organic growth investments, the pursuit of strategic acquisitions, and the return of excess capital to shareholders.

“We remain optimistic regarding the long-term outlook for power transmission spending, supported by an aging utility infrastructure and the continued electrification of the economy. Our industry-leading matting fleet provides the scale and flexibility to capitalize on these trends, as reflected by the strength in our commercial pipeline, with our quoted volumes up approximately 30% from year-end 2024. Based on this momentum, we are introducing full-year 2026 guidance which reflects year-over-year revenue and Adjusted EBITDA growth of 14% and 25%, respectively, at the midpoint of our range, driven primarily by anticipated low-to-mid teens percentage growth in rental and service revenues.

“As we look ahead, our strategic priorities remain unchanged - delivering consistent organic growth, driving organizational efficiencies, and enhancing returns on invested capital through a disciplined approach to capital allocation,” concluded Lanigan. “We are excited about the opportunities ahead and remain confident in our ability to execute on our objectives in 2026 and beyond.”

BUSINESS UPDATE

NPK’s business plan is designed to drive organic commercial growth within targeted rental and product sale 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.

Fourth quarter and full-year 2025 highlights include:

• Strong customer demand continued for matting rental and related services. Revenues from specialty rental and related services were $50 million in the fourth quarter of 2025, with strong demand continuing in support of power transmission projects. Revenues from product sales were $25 million for the fourth quarter of 2025, the Company’s strongest quarter of the year, primarily reflecting continued strength in demand from utility companies. For the full year 2025, rental and service revenues increased 26% year-over-year, while revenues from product sales increased 30%. More than two-thirds of 2025 revenue was derived from the power transmission sector.
• Manufacturing efficiency and capacity expansion. Production volumes increased more than 15% year over year in 2025 benefitting from a shift to 24/7 operations and throughput enhancements. These initiatives are anticipated to provide an additional increase in production capacity in 2026, sufficient to support anticipated growth. Management continues to evaluate additional manufacturing expansion alternatives and expects to finalize investment plans and timelines over the next few months.
• Pursuit of operational efficiency. During 2025, the Company completed the required transitional support for the divested Fluids business while simultaneously advancing a major ERP conversion project. The new ERP system has been recently rolled out to all legacy operations and represents yet another significant milestone in the efforts to streamline overhead and SG&A costs, consistent with the Company’s goal to drive SG&A costs down to a mid-teens percentage of revenue.
• Enhanced return on invested capital. The Company delivered an after-tax return on net assets of 11% in 2025, a substantial year-over-year improvement, driven by a combination of improved profitability and focused balance sheet management.
• Return of capital to shareholders. The Company continued to execute on its disciplined return of capital strategy during 2025 by repurchasing 4% of outstanding shares at an average price of $6.70 per share. As a result, the Company exited 2025 with two million fewer shares outstanding versus the prior year.
• Acquisition of Grassform. On November 24, 2025, the Company 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. The purchase price at closing for this acquisition was $42 million net of cash acquired, and was funded with cash on hand and borrowings under the Credit Facility. It is anticipated that the acquisition will meaningfully strengthen U.K. operations through scale and the addition of a highly tenured and talented team.
