NPK International Inc. Q1 2026 Earnings Recap

NPK International shares declined 4.8% after Q1 earnings as investors reacted to notable margin compression despite record revenues and raised full-year guidance. Weaker gross margin, down both sequentially and year-over-year, appears to have overshadowed solid top-line growth and positive outlook commentary.

Key Takeaways

• Gross margin declined to 36.2% (vs. 37.7% in Q4 and 39% a year ago), pressured by lower fleet utilization early in the quarter and ongoing cross-rental costs.
• Total rental and service revenues hit a quarterly record at $52 million, up 20% year-over-year; product sales reached $23 million, rising 8%.
• Adjusted EPS was $0.12, flat year-over-year and slightly below last quarter's $0.13.
• The company raised 2026 revenue guidance to $310–$325 million and adjusted EBITDA to $92–$102 million, targeting 15% revenue and 28% EBITDA growth at the midpoint.
• Free cash flow totaled $5 million; $3 million was used for share repurchases, with net debt reduced to $4 million and substantial liquidity remaining for planned manufacturing expansion.
