NPK International Inc., formerly known as Newpark Resources, Inc., specializes in providing worksite access solutions and specialty rental services for critical infrastructure markets. The company's core product is the DURA-BASE Advanced Composite Mat System, which offers durable ground protection and temporary roadways for challenging environments. Following the divestiture of its legacy Fluids Systems segment in 2024, NPK transitioned into a pure-play specialty rental and services business. The company generates the majority of its revenue from the rental of its composite matting systems, complemented by related site construction and environmental remediation services. NPK serves a diverse customer base across power transmission and distribution, oil and natural gas exploration, pipeline construction, and renewable energy sectors.
