Key Points

• NPK reported a strong Q1 with record rental and service revenue of $52 million (up 20% YoY), adjusted EBITDA of $22 million (up 14% YoY), $21 million operating cash flow, $5 million free cash flow, and net debt of $4 million after repaying the revolver and repurchasing $3 million of shares.
• The board approved a roughly 50% manufacturing capacity expansion with planned investment of $40–45 million over the next five quarters to come online by mid‑2027, and 2026 net CapEx guidance was raised to $75–90 million (including $35–45 million for rental fleet growth).
• NPK raised its full‑year 2026 guidance to $310–325 million revenue and $92–102 million adjusted EBITDA (midpoints imply ~15% revenue and 28% EBITDA growth), with rental and service revenues expected to grow about 20% YoY in Q2 and the Grassform acquisition contributing to recent gains.

NPK International NYSE: NPKI reported first-quarter 2026 results that management said were in line with expectations, highlighting record rental and service revenue, higher adjusted EBITDA, and positive free cash flow while continuing to invest in fleet growth and a newly approved manufacturing capacity expansion.

Quarterly performance and record rental and service revenue

President and CEO Matthew Lanigan said the company was “very pleased with our strong start to 2026,” noting that rental activity accelerated as the quarter progressed despite a typical pause in customer projects around the year-end holidays.

Lanigan said total rental and service revenues reached a quarterly record of $52 million, up 4% sequentially and 20% year over year. He also said product sales demand remained “robust,” contributing $23 million to first-quarter revenue. Adjusted EBITDA totaled $22 million, up 4% sequentially and 14% from the prior-year quarter, according to management.

SVP and CFO Gregg Piontek provided additional detail, saying rental revenues increased 27% year over year, reflecting 12% organic growth and a $4 million contribution from the Grassform acquisition. Piontek said service revenues rose 7%, with “substantially all” of the increase also coming from the acquisition. Product sales revenue of $23 million represented an 8% year-over-year improvement, which Piontek attributed to continuing demand from utility customers.

Segment and geographic trends, margins, and costs

By geography, Piontek said U.S. revenues increased 9% year over year to $66 million, including 17% growth in rental revenues, with the utility sector driving the “substantial majority” of the increase. U.K. revenues more than doubled to $9 million, “primarily reflecting the Grassform contribution,” he said.

First-quarter gross margin was 36.2%, down from 37.7% in the fourth quarter and 39% in the prior-year quarter. Piontek said the sequential decline was primarily due to lower rental fleet utilization early in the quarter stemming from the timing of large-scale projects, partially offset by improved pricing. The year-over-year decline, he added, reflected the continuing impact of cross-rental costs discussed in prior quarters.

Piontek emphasized that the cross-rental fleet supports the company’s ability to meet customer commitments while helping “limit inefficient transportation.” Lanigan later noted that cross-rental capacity can help offset internal transport charges associated with moving fleet assets between projects, particularly as diesel prices have risen alongside the Middle East conflict.

SG&A expenses totaled $13.2 million, compared with $15.4 million in the fourth quarter and $11.7 million a year earlier. Piontek said first-quarter SG&A included $12.5 million from the legacy business and $700,000 tied to Grassform, while the fourth quarter had included $1.8 million of acquisition-related transaction costs and severance.

Income tax expense was $3.6 million, reflecting an effective tax rate of 26%, Piontek said. Adjusted EPS from continuing operations was $0.12 per diluted share, compared with $0.13 in the fourth quarter and $0.12 in the year-ago quarter.

Cash flow, balance sheet, and capital allocation

Management highlighted cash generation and balance sheet capacity alongside continued investment. Lanigan said the company generated $21 million of cash flow from operations and $5 million of free cash flow, expanded the rental fleet by 4%, repaid its revolving credit facility, and used $3 million for share repurchases.

Piontek said operating cash flow of $21 million included $22 million from net income adjusted for non-cash expenses, slightly offset by $1 million of cash used by a net increase in working capital. Net capital expenditures totaled $16 million, including nearly $15 million of net investment into rental fleet expansion. The company ended the quarter with $11 million of total debt and $7 million of total cash, for net debt of $4 million, Piontek said, adding that the firm had $148 million of availability under its bank facility.

On capital allocation, Piontek said priorities include rental fleet growth, the manufacturing expansion, strategic acquisitions, and returning a portion of free cash flow to shareholders through a “disciplined” share repurchase program.

Manufacturing expansion approved; investments planned through mid-2027

Lanigan said the board approved plans to increase production capacity by approximately 50% from current levels after the company “substantially concluded” its project evaluation. Management expects to invest $40 million to $45 million over the next five quarters, targeting the additional capacity to come online by mid-2027.

Asked about the expansion’s runway, Lanigan said the plant should provide “plenty of capacity through the end of the decade,” depending on market growth, and noted the company has “plenty of room” at its Louisiana facility if it chose to co-locate further expansion, while also retaining the option to evaluate alternate sites. On timing and cost risk, Lanigan said project timelines and budgets can shift, but he said the company feels “pretty good” about delivering within the timeframe and cost range provided.

Outlook raised; project timing and market conditions discussed

Piontek said the company raised its full-year 2026 outlook, citing constructive customer views on utility and critical infrastructure spending and momentum coming out of the first quarter. The updated guidance calls for:

• Total revenue: $310 million to $325 million
• Adjusted EBITDA: $92 million to $102 million

Piontek said the midpoint implies 15% revenue growth and 28% adjusted EBITDA growth over 2025. The revenue outlook assumes double-digit organic rental revenue growth plus Grassform, while product sales are expected to be “relatively in line” with 2025.

For 2026 capital spending, Piontek guided to total net CapEx of $75 million to $90 million, including $30 million to $35 million of current-year spending for the manufacturing expansion and $35 million to $45 million for rental fleet expansion. He said the investment plan is expected to grow the DURA-BASE rental fleet by a “low to mid-teens” percentage, supporting organic growth and displacing some cross-rent assets currently deployed.

In the near term, Piontek said the company expects 20% year-over-year growth in rental and service revenues in the second quarter, with product sales roughly in line with the prior-year second quarter. He said second-quarter gross margin is expected to be roughly consistent with the prior-year second quarter but dependent on the timing of project completions and fleet redeployments for several large-scale jobs. SG&A is expected to remain near the $13 million quarterly level, and the effective tax rate is expected to remain relatively in line with the first-quarter level for full-year 2026. Piontek also said the company entered the year with roughly $40 million of net operating losses and other tax credit carryforwards, which, along with accelerated deductions for capital investments, are expected to “significantly limit” cash taxes for the next several years.

During Q&A, Lanigan said it is “still a little early” for some larger high-voltage utility projects, which he expects later in the year. He described the pipeline as remaining “as robust as where we left it last quarter,” with slight growth in quoting activity in emerging territories. Asked whether later high-voltage projects could imply faster growth into 2027, Lanigan said it was too early to quantify but noted those projects carry larger matting requirements due to heavier equipment and could represent a “net increase in matting requirement.”

Lanigan also said rental pricing increases were in the “low single digit” range, citing some “tightness in the market,” and said the company expects to hold pricing and potentially add to it as the year progresses. On the competitive mix of composite versus timber matting, Lanigan estimated composite represents “roughly a quarter of the market” and said that percentage could hold if overall market growth remains strong.

Regarding Grassform, Lanigan said the company expects to complete “substantially most” integration within three to six months, with ERP conversion potentially extending the tail, adding that NPK’s approach has been to avoid distracting a “very well-run business.” On future M&A, Lanigan said NPK would consider acquisitions where it could accelerate composite matting share gains versus timber incumbents, alongside typical diligence considerations such as leverage, management strength, and contract quality.
