Linde plc is the world's largest industrial-gas company by revenue. It generated $34.0 billion of FY2025 sales and $10.1 billion of adjusted operating profit, an industry-leading 29.8% adjusted margin. The company produces and distributes atmospheric gases (oxygen, nitrogen, argon, rare gases) and process gases (hydrogen, helium, CO2, CO, electronic and specialty gases, acetylene) through three supply modes: on-site/pipeline, merchant bulk and packaged cylinders. Customers span chemicals and energy, healthcare, manufacturing, metals and mining, food and beverage, and electronics in roughly 80+ countries. A captive engineering arm, Linde Engineering, designs air-separation, hydrogen/syngas, olefin and natural-gas plants. Its economics rest on dense regional networks, take-or-pay contracts of 10–20 years and contractual energy pass-through, which together produce utility-like cash flows: $10.4 billion of FY2025 operating cash flow. Strategy combines pricing discipline, productivity and a contracted project backlog (about $11 billion at Q2 2026), with growing exposure to semiconductors, commercial space and low-carbon hydrogen.

### Company's own description (FY2025 Form 10-K, Item 1)
The 10-K describes Linde as the largest industrial gas company worldwide and a major technological innovator in industrial gases.
- **Primary products:** atmospheric gases (oxygen, nitrogen, argon and rare gases) and process gases (hydrogen, helium, carbon dioxide, carbon monoxide, electronic gases, specialty gases and acetylene).
- **Engineering offering:** Linde designs and builds gas-production and gas-processing plants, including olefin, natural-gas, air-separation, hydrogen and synthesis-gas plants.
- **Industries served:** healthcare, chemicals and energy, manufacturing, metals and mining, food and beverage, and electronics.
The earnings-release boilerplate (Q2 2026) frames the mission as "making our world more productive". It highlights space-launch propellants, ultra-high-purity gases for semiconductor fabs, medical oxygen, clean hydrogen and carbon capture.
### Business model and revenue model
Linde's revenue is overwhelmingly product sales under contract, not subscription or licensing. The model has four supply channels, set out below with the FY2025 revenue split by distribution channel (Fiscal.ai via StockAnalysis.com; company 10-K for contract terms).
The service component (cylinder rental, homecare via Lincare in the US, plant operations, digital services) is embedded in these channels and is not separately disclosed.
- **Licensing:** Linde licenses process technology through Linde Engineering (e.g., air separation, HISORP carbon capture, olefin and LNG processes), but licence income is not separately disclosed (n.p.d.).
- **Energy pass-through:** energy is the single largest cost. Large contracts carry pass-through and escalation clauses, so reported sales move with energy prices ("cost pass-through") with minimal profit impact.
### Value-chain position
Linde is vertically integrated from technology and plant design (Linde Engineering), through production (approximately 855 major cryogenic ASU/H2/CO2 plants across the three regions per the 10-K property description), to distribution (pipelines, tanker fleet, cylinder depots, retail stores) and application know-how at the customer site.
Upstream inputs are electricity, natural gas and purchased raw gases. Hydrogen, CO2 and calcium carbide are often sourced as by-products, and helium comes from US natural gas streams and imports.
The Engineering segment both sells plants to third parties and builds plants for Linde's own gas business. Intersegment sales from Engineering to the gas segments were $2,702m in FY2025, against $1,958m in 2024 and $1,479m in 2023, showing rising internal capital deployment.
### Customer types and end-markets
The 10-K states that Linde is not dependent on any single customer or small group of customers.
### Independent characterization
Linde is best understood as a regulated-utility-like infrastructure owner with commercial pricing freedom. About one quarter of revenue is long-dated, take-or-pay on-site supply, which provides a floor. The merchant and packaged businesses, about 65% of revenue, are local oligopolies. Transport economics limit competition to a radius of a few hundred miles, so network density converts directly into pricing power.
Linde's distinguishing trait relative to peers is capital discipline. It typically commits capital only against secured offtake, and it prices to recover inflation. This has delivered steady price attainment of 2–4% a year even through flat or negative base volumes (FY2025 volumes: 0%).
The principal earnings risk is not demand collapse but volume stagnation in cyclical industrial end-markets (notably Europe) together with engineering-project execution, as illustrated by the Russian Amur gas processing plant dispute.
