NPK International Inc. reports strong growth in its 2025 annual filing. Revenue rose to $277.0 million, a 27% increase from 2024, with 66% from rental and services and 34% from product sales. Operating income from continuing operations increased 45% to $46.8 million, while income from continuing operations was $35.9 million.
Growth was driven by higher rental volumes, particularly larger, longer-term utility projects, and increased composite mat product sales as customers shifted away from timber-based solutions. The company expanded its rental fleet by about 16%, acquired U.K. ground protection provider Grassform, and invested heavily in a new cloud ERP and added manufacturing capacity.
Net cash from operations nearly doubled to $73.0 million, supporting $46.7 million of capital spending and the Grassform acquisition. NPK also repurchased 3.0 million shares, about 4% of its outstanding stock, for $20.4 million, leaving $91.7 million remaining under its authorized buyback program.

In 2025, the company generated $277 million in revenue and $76 million in Adjusted EBITDA, reflecting 27% and 38% year-over-year growth, respectively, with an Adjusted EBITDA margin of 27.3%. Growth was driven by rental revenues tied to power transmission projects and robust product sales to utility customers, while composite matting remained the core specialty rental asset.
The company ended 2025 with about $12 million of Net Debt and roughly $145 million of available liquidity, supporting both organic fleet expansion and share repurchases. For full-year 2026, guidance calls for revenues of $305–$325 million and Adjusted EBITDA of $88–$100 million, implying further double-digit growth, along with planned net capital expenditures of $45–$55 million focused mainly on rental fleet investments.

NPK issued 2026 guidance calling for revenue of $305–$325 million and Adjusted EBITDA of $88–$100 million, implying mid‑teens revenue growth and mid‑20s Adjusted EBITDA growth at the midpoint, driven largely by continued strength in rental and service demand in power transmission markets.
