Management Comments

• "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."

• "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."

Industry Context

StockSavvy.ai notes that NPK International's strong performance, particularly in rental revenues and its focus on the power transmission sector, aligns well with broader industry trends. The increasing investment in aging utility infrastructure and the global push towards electrification are significant tailwinds for companies providing essential worksite access solutions. The reported 30% increase in quoted volumes from year-end 2024 suggests continued robust demand, positioning NPKI favorably against competitors in this growing market. The acquisition of Grassform also indicates a strategic move to consolidate and strengthen its position in key international markets like the U.K., where infrastructure spending is also a priority.
