Park Ohio Holdings Corp (NASDAQ: PKOH)

Park-Ohio Holdings Corp. is a diversified international company that provides supply chain management outsourcing, capital equipment for production lines, and manufactured components used to assemble products. It operates in the industrial manufacturing and supply chain services sector, serving a broad range of original equipment manufacturers and industrial customers worldwide.

The company generates revenue through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. In 2025, Supply Technologies contributed $747.5 million, Assembly Components contributed $380.6 million and Engineered Products contributed $471.0 million in net sales. Revenue is derived from services such as total supply management, engineering and design support, just in time delivery and inventory management, as well as the manufacture of fuel rails, filler pipes, turbocharger hoses, induction heating and melting systems, pipe threading equipment and forged or machined components. Customers include original equipment manufacturers and industrial firms across sectors such as automotive, aerospace, defense, construction, oil and gas and metals processing.

The company operates through the following segments: Supply Technologies, Assembly Components and Engineered Products.

• Supply Technologies provides total supply chain management services including strategic planning, sourcing, procurement of over 280,000 production components, engineering and design support, part usage and cost analysis, supplier selection, quality assurance, bar coding, product packaging and tracking, just in time and point of use delivery, electronic billing and ongoing technical support. The segment operates approximately 80 logistics service centers across the United States, Mexico, Canada, Europe and Asia and manufactures precision cold formed and cold extruded fasteners such as locknuts, SPAC nuts and bolts for high vibration applications in automotive, heavy duty truck and aerospace markets.

• Assembly Components designs, develops and manufactures highly efficient high pressure direct fuel injection fuel rails and pipes, fuel filler pipes that route fuel from the gas cap to the tank, and flexible multi layer plastic and rubber assemblies used to transport fuel from the tank to the injector nozzles. The segment also produces turbo charging hoses and turbo coolant hoses required for downsized engines. Assembly Components operates 11 manufacturing facilities and three technical offices in the United States, Mexico, China, the United Kingdom and the Czech Republic and provides value added services such as design engineering, machining and parts assembly.

• Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture induction heating and melting systems, pipe threading systems and forged and machined products. The segment maintains 13 domestic facilities in the United States and 19 international facilities in Canada, Mexico, the United Kingdom, Belgium, Germany, China, Italy, India, Japan, Spain, France and Brazil. Its products serve the ferrous and non ferrous metals, silicon, coatings, forging, foundry, automotive, truck, construction equipment, oil and gas, rail and aerospace and defense industries, with field service and replacement parts representing a significant portion of revenue.

The company holds a strong position in its respective markets by leveraging integrated supply chain solutions and specialized manufacturing capabilities. Supply Technologies differentiates itself from traditional distributors and manufacturers through its total supply management approach, which combines engineering support, global sourcing, logistics and inventory management, and benefits from extensive geographic reach and a broad product selection. Assembly Components faces limited domestic competition and competes on its ability to engineer high quality, cost effective fuel system assemblies, provide timely delivery and maintain manufacturing flexibility. Engineered Products competes with small to medium equipment makers on service capability, ability to meet customer specifications, delivery performance and engineering expertise, and with forging and machining businesses on product quality and precision. Across all segments, long term sole source contracts and an average client tenure exceeding ten years for top Supply Technologies customers create stable, recurring revenue streams and high switching costs for buyers.

The company serves a diverse customer base that includes original equipment manufacturers and industrial firms in sectors such as heavy duty truck, power sports and recreational equipment, aerospace and defense, semiconductor equipment, electrical distribution and controls, consumer electronics, bus and coaches, automotive, agricultural and construction equipment, HVAC, lawn and garden, plumbing, medical devices, locomotive manufacturers, railcar builders and maintenance providers, and oil and gas companies. While the filing does not disclose individual customer names, it notes that the five largest customers in each segment represent a significant portion of segment sales, underscoring the importance of key relationships.
