Linde plc (LIN): Who It Depends On
Linde plc is the world's largest industrial gas company, producing oxygen, nitrogen, hydrogen, argon and other gases through large on-site plants, pipeline networks and merchant distribution built to serve refineries, steel mills, chemical plants, semiconductor fabs and hospitals. Its supply-chain story is less about single-vendor risk and more about the categories its own 10-K flags as core cost and availability risks: natural gas feedstock and electricity, which Linde calls the single largest cost item in producing industrial gases, plus other purchased raw materials like helium and the specialized cryogenic equipment and construction capacity needed to keep building its roughly $10 billion project backlog. On the customer side, Linde's own filings state it is "not dependent upon a single customer or a few customers," so rather than force a misleading concentrated-customer chart, this page highlights the large, publicly documented on-site relationships it does have - like its long-term semiconductor gas-supply deals with TSMC and Samsung and its record hydrogen contract with Dow - alongside the broader end-markets that make up the rest of its diversified base.
Supply-chain dependency
Linde is unusual among large equipment-dependent industrials in that it is largely its own engineer and builder: its in-house Linde Engineering division designs and constructs the majority of its air separation and hydrogen units, and its 10-K does not name individual outside equipment or construction vendors the way some companies disclose sole-source component risk. The dependencies Linde does disclose run through categories rather than named companies - the cost and availability of natural gas feedstock and electricity (which Linde's own filings call the single largest cost item in industrial gas production), other purchased raw materials such as helium, and the limited global pool of manufacturers capable of building large cryogenic and turbomachinery equipment. This chart reflects those disclosed categories rather than inventing specific vendor relationships Linde does not name.
Not a single company. Linde produces most of its hydrogen and synthesis gas through steam methane reforming and auto-thermal reforming, both of which convert natural gas into hydrogen, and Linde's 10-K identifies the cost and availability of natural gas as a direct risk to these operations, even though many on-site contracts pass feedstock costs through to customers over time.
Not a single company. Linde's own SEC filings state that energy is the single largest cost item in producing and distributing industrial gases. Air separation units and electrolysis-based hydrogen plants are highly power-intensive, leaving Linde exposed to regional electricity prices and grid reliability everywhere it operates a plant.
Not a single company. Linde's 10-K discloses that raw materials for hydrogen, helium, carbon dioxide, carbon monoxide and specialty gases are largely purchased from outside sources whose long-term availability and pricing are subject to market conditions. Global helium supply is especially concentrated in a handful of sources, including Qatar's Ras Laffan complex, which saw acute disruption in 2026.
Not a single company. Air separation units and hydrogen plants depend on large centrifugal compressors, cryogenic cold boxes and turboexpanders that only a small number of global manufacturers can build at the scale and precision Linde requires, making this specialized equipment capacity a structural bottleneck for new plant construction across the industry.
Not a single company. Linde designs much of its own plant technology in-house through its Linde Engineering division, but executing its roughly $10 billion project backlog - including its largest-ever single sale-of-gas project, a clean hydrogen and nitrogen complex being built for Dow in Alberta - still depends on outside construction contractors, skilled labor and on-time delivery at large industrial sites.
Not a single company. The vessels, piping and heat exchangers used across Linde's on-site and merchant plants require specialty steel and metal alloys engineered to withstand cryogenic temperatures, exposing construction costs and lead times to swings in global steel and alloy markets.
Customer concentration
Linde's own 10-K states plainly that it "is not dependent upon a single customer or a few customers" - its revenue is spread across thousands of industrial and healthcare accounts worldwide, and no single buyer approaches the concentration seen at companies with a handful of large customers. Rather than force a misleading top-10-by-revenue list, this chart highlights the specific large, long-term on-site contracts and end-market groupings that are the most meaningful expressions of customer reliance Linde actually has - most notably its multi-decade on-site gas supply relationships with major semiconductor manufacturers and its largest-ever single sale-of-gas contract with Dow - alongside the broader end markets (manufacturing, chemicals & energy, metals & mining, healthcare, food & beverage) that make up the rest of its diversified revenue base.
Linde's largest end market by revenue, spanning metal fabrication, welding, automotive, aerospace and general industrial manufacturing customers supplied through both bulk on-site plants and cylinder/merchant gas distribution. No individual account in this broad category approaches material concentration.
Refiners, petrochemical producers and other energy customers that take hydrogen, nitrogen, oxygen and other process gases under long-term, typically 10-20-year, take-or-pay on-site contracts - one of Linde's largest and most cyclical end markets outside of its single largest chemicals contract with Dow.
Linde is investing more than $2 billion to build and operate a large-scale autothermal reforming and carbon-capture hydrogen complex supplying clean hydrogen and nitrogen to Dow's Path2Zero net-zero ethylene project in Fort Saskatchewan, Alberta - publicly described by Linde as its largest-ever single sale-of-gas project and roughly half of its record project backlog.
Steelmakers and other metals producers that rely on large volumes of oxygen and nitrogen for blast furnaces, electric-arc furnaces and other high-temperature processes, typically supplied through dedicated on-site plants under multi-year contracts. Linde has separately expanded a long-running supply agreement with India's Steel Authority of India and signed deals to supply gases to large-scale green-steel projects.
Linde agreed to invest roughly $600 million to build, own and operate a complex of on-site plants supplying ultra-high-purity nitrogen, oxygen and argon to TSMC's Fab 21 semiconductor complex in Phoenix, Arizona, and Linde's own 2026 earnings commentary points to the ramp of that site as a specific growth driver.
Linde has supplied industrial gases to Samsung in South Korea for more than 45 years and is building an eighth on-site air separation unit at Samsung's Pyeongtaek complex, which Linde describes as its single largest site anywhere in the world supplying an electronics customer. Samsung Electronics trades primarily on the Korea Exchange, with no proper US-listed ticker.
Not a single company. Beyond its named U.S. and South Korean projects, Linde supplies ultra-pure bulk and specialty gases to other semiconductor, display and solar manufacturing customers globally, an end market Linde highlights as a structural growth driver tied to AI-related chip capacity expansion.
Not a single company. Linde supplies medical oxygen, nitrous oxide and other gases plus related equipment and homecare services to hospitals, clinics and homecare patients worldwide - a large, stable but highly fragmented end market with no individually material customer.
Not a single company. Linde supplies carbon dioxide and nitrogen for beverage carbonation, food freezing and modified-atmosphere packaging to food and beverage producers and distributors worldwide, a diversified end market rather than a concentrated customer base.
Not a single company. The remainder of Linde's revenue comes from tens of thousands of smaller industrial, welding, laboratory and merchant/packaged-gas customers worldwide, none individually material - the diversification Linde's own 10-K points to when it states the company is "not dependent upon a single customer or a few customers."
