Foster l B Co: what insiders have been doing
Foster l B Co is a Industry company. Its directors and officers file their transactions with SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 71 filings came from 16 insiders.
All open-market trades in the period are sales: 16 sales worth €5.5M, by 2 insiders, with no purchase on record. Biggest ticket of the year: €1.9M, sold by English Aron R. and made public on 25 March 2026.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 5 days. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
Across the 5,811 companies tracked on its exchange, the median is 19 filings; at 71 filings, this issuer sits above that mark. The full history, which starts in 2016, counts 11 purchases against 16 sales. The 10-K for the year ended 31 December 2025 shows 540.0 m USD of revenue and 7.5 m USD of net income.
In the same sector, recent insider purchases at Tennant Co and Butler National Corp also feature in our signals. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.

About Foster l B Co
L.B. Foster Company (ticker: FSTR) is a U.S.-listed industrial company traded on the Nasdaq Global Select Market in the United States. Founded in 1902 and headquartered in Pittsburgh, Pennsylvania, the company develops, manufactures, distributes, and services products for rail and infrastructure end markets. Its business model is built around engineered solutions and mission-critical applications rather than commodity manufacturing, which gives it a niche position in transportation infrastructure and industrial maintenance.
Today, L.B. Foster reports through two operating segments: Rail, Technologies, and Services; and Infrastructure Solutions. The Rail segment includes rail products, global friction management, and technology services and solutions, along with project management and aftermarket services. The Infrastructure segment includes precast concrete products, steel products, and protective coatings-related capabilities. Management presents the company as a global technology solutions provider for rail and infrastructure markets, serving freight and passenger railroads as well as industrial customers and infrastructure owners. This mix provides some balance between recurring aftermarket/service revenue and more project-driven demand tied to infrastructure spending.

Geographically, the company maintains locations in North America, South America, Europe, and Asia. Its revenue base remains heavily weighted toward the United States, while its operating footprint extends through facilities and sales offices in Canada, the United Kingdom, and other international markets. That geographic reach supports access to a broad customer base and helps L.B. Foster participate in rail maintenance cycles and infrastructure investment programs across multiple regions. At the same time, the business is still exposed to construction and rail spending cycles, commodity input volatility, and the timing of large projects.
Recent company developments have centered on portfolio simplification, margin improvement, and cash generation. In 2024, L.B. Foster completed an enterprise restructuring program designed to reduce costs and support investment in growth platforms, with expected annual run-rate pre-tax savings of about $4.5 million. The company also continued optimizing certain product lines, including exiting lower-priority activities. More recently, it reported strong fourth-quarter 2025 results, with the highest fourth-quarter net sales since 2018 and a meaningful improvement in profitability and operating cash flow. In May 2026, it announced a solid first-quarter 2026 performance and reaffirmed full-year guidance, reinforcing the view that execution is improving. For investors, FSTR is best viewed as a U.S. industrial infrastructure name with a specialized rail franchise, a broad but selective global footprint, and an improving operational profile.
