====== Industrial Gases ======
Industrial gases are a fascinating and often overlooked cornerstone of the modern economy. These aren't the gases you fill party balloons with; they are gaseous materials manufactured in vast quantities for critical use across an incredible spectrum of industries. The main players in this space form a global oligopoly, including giants like [[Linde]], [[Air Liquide]], and [[Air Products and Chemicals]]. These companies produce essential gases like oxygen, nitrogen, argon, hydrogen, and helium. At first glance, it might seem like a boring commodity business, but nothing could be further from the truth. The magic lies in their business model. These gases are fundamental inputs for everything from steelmaking and oil refining to semiconductor fabrication and food preservation. Because they are often consumed in huge volumes and are difficult to store and transport, the relationship between a supplier and its customer is exceptionally deep and durable, creating a powerful business structure that should make any value investor's ears perk up.
===== The Business Model: Why It's a Gem =====
The genius of the industrial gas business isn't just selling gas; it's about selling a mission-critical, integrated service that becomes deeply embedded in the customer's operations. This creates one of the widest and most durable [[competitive advantages]], or "moats," you can find.
==== The "Razor and Blades" Model on Steroids ====
For large customers, like a steel mill or a chemical plant, gas suppliers don't just deliver cylinders. Instead, they often build a dedicated production facility, such as an [[Air Separation Unit (ASU)]], directly on or next to the customer's site.
  * **The Razor:** The multi-million dollar on-site production plant.
  * **The Blades:** A long-term (typically 15-20 year) "take-or-pay" contract for a guaranteed supply of gas. The customer //must// pay for a minimum volume, whether they use it or not.
This creates incredibly high [[switching costs]]. Once that plant is built, the customer is locked in. Tearing it down and having a competitor build a new one is prohibitively expensive and disruptive. This arrangement provides the gas company with a highly predictable, recurring revenue stream that is the envy of almost any other industry.
==== A Local Oligopoly ====
While the major players are global, the business itself is intensely local. Transporting cryogenic liquids or high-pressure gases is expensive and inefficient over long distances. The practical delivery radius from a production plant is typically only a few hundred kilometers. This economic reality carves the world into regional markets where one or two suppliers dominate. This structure is a classic [[oligopoly]], which grants the dominant companies significant [[pricing power]]. They aren't competing with a supplier from the other side of the country; they are competing with the one or two others who have a dense production and distribution network in that specific region.
===== A Value Investor's Perspective =====
For followers of [[value investing]], the industrial gas sector is a textbook example of a high-quality business that consistently compounds capital over time.
==== Durable Competitive Advantages (The Moat) ====
The moats protecting these companies are deep and multi-faceted:
  * **High Switching Costs:** As mentioned, the on-site contract model is the ultimate customer trap.
  * **[[Network Effects]]:** For smaller "merchant" customers who buy gas in cylinders, the supplier with the densest and most efficient delivery network wins. A larger network lowers delivery costs per customer, creating a scale advantage that is difficult for new entrants to replicate.
  * **Intangible Assets:** Decades of process knowledge, engineering expertise, and patents for gas applications give incumbents a major edge.
==== Key Financial Metrics to Watch ====
When analyzing an industrial gas company, focus on these metrics:
  * **[[Return on Invested Capital (ROIC)]]:** This is arguably the most important metric. Building on-site plants requires enormous [[capital expenditure (CapEx)]], so a consistently high ROIC proves that the company is deploying that capital wisely and earning returns that exceed its cost of capital.
  * **[[Free Cash Flow (FCF)]]:** Thanks to the long-term contracts, these businesses are cash-generating machines. Strong and predictable FCF allows them to pay dividends, buy back shares, and reinvest in new, high-return projects.
  * **Operating Margins:** Strong [[profit margins]] are a sign of pricing power and operational efficiency. Pay attention to how margins behave during economic downturns.
===== Risks to Consider =====
No investment is without risk, and even these high-quality businesses have things to watch out for.
  * **Cyclicality:** The fortunes of industrial gas companies are tied to the health of the industrial economy. A severe recession will reduce demand from their core customers in manufacturing, chemicals, and steel. However, a growing portion of their business now comes from more defensive sectors like healthcare and food & beverage, which helps cushion the blow.
  * **Energy Costs:** Separating gases from the air is an extremely energy-intensive process. Spikes in the price of electricity and natural gas can compress margins, although many long-term contracts include clauses that pass these higher costs on to the customer.
