NPK International Inc.: what insiders have been doing
Every trade that managers of NPK International Inc. disclose to SEC (Form 4) is tracked on this page. The company sits in the Construction sector and is based in The Woodlands, United States. It was founded in 1932. From 18 October 2025 to 18 October 2026, the disclosure feed for NPK International Inc. logged 28 filings by 13 insiders.
There is no open-market purchase to report; the filings show 9 sales worth €1.1M by 4 insiders. No amount is published for 1 filing, which the totals therefore leave out. Piontek Gregg filed the largest sale, €438k, on 3 April 2026, which represents 0.034% of the company's market value.
With 28 filings in twelve months, the company is more active than the median of 22 filings across the 5,458 companies we follow on the same exchange. The full history, which starts in 2016, counts 20 purchases against 15 sales. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 277.0 m USD and net income at 38.9 m USD.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.

About NPK International Inc.
NPK International Inc. (NYSE: NPKI) is a United States-listed company focused on temporary worksite access solutions. The company designs, manufactures, sells, and rents recyclable composite matting products that are used to stabilize ground conditions, protect surfaces, and create safer access routes for infrastructure, energy, construction, industrial, and event-related projects. Its model is broader than a simple product business: NPK also provides a full suite of services that includes planning, logistics, installation, and site restoration, which helps it capture more value across the project lifecycle.

From an operating perspective, NPK’s core competitive advantage lies in combining proprietary matting products with service capabilities. The company earns revenue from both sales and rentals, giving customers flexibility depending on project duration, capital constraints, and site requirements. This mixed model can be attractive in industries where short-term deployment, rapid mobilization, environmental protection, and safety compliance are key buying criteria. The rental component also tends to support recurring revenue visibility relative to a pure equipment sales model. ([nasdaq.com](https://www.nasdaq.com/press-release/npk-announces-new-150-million-revolving-credit-facility-2025-06-23?utm_source=openai))
In competitive terms, NPK occupies a specialized niche in a market where contractors and industrial operators increasingly value durable, reusable access solutions that reduce ground damage and improve site efficiency. Its positioning is supported by an environmentally oriented product set and a service-led offering that can deepen customer relationships. While the company has indicated international activity, the United States remains its primary base and most important commercial anchor. ([nasdaq.com](https://www.nasdaq.com/press-release/npk-announces-new-150-million-revolving-credit-facility-2025-06-23?utm_source=openai))
Recent developments have been constructive. In June 2025, NPK announced a new $150 million revolving credit facility with a five-year term and accordion capacity up to $250 million, enhancing financial flexibility. In February 2026, the company reported fourth-quarter 2025 revenue of $75.2 million, higher rental revenue, and provided 2026 guidance for revenue of $305 million to $325 million and Adjusted EBITDA of $88 million to $100 million. In November 2025, NPK also announced the acquisition of Grassform Plant Hire in the United Kingdom, reinforcing its international footprint and suggesting ongoing consolidation in its niche market.
