Hexcel (NYSE: HXL)

• The Bottom Line: Hexcel is a high-quality, wide-moat industrial company that manufactures the “bones and skin” of modern aircraft, but its fortunes are chained to the brutally cyclical aerospace industry.
• Key Takeaways:
• What it is: Hexcel is a leading producer of advanced composite materials—think carbon fiber and other high-tech fabrics that are stronger than steel but lighter than aluminum.
• Why it matters: The company sits at the heart of a multi-decade trend towards lighter, more fuel-efficient aircraft, giving it a powerful, long-term tailwind. Its products are so critical and difficult to replace that it enjoys a formidable economic_moat.
• How to analyze it: To understand Hexcel, you must ignore the daily stock price noise and instead focus on aircraft manufacturing backlogs, the value of its content per plane (shipset value), and, most importantly, buying it only when a cyclical downturn provides a deep margin_of_safety.

Imagine you're building the most advanced Lego model in the world—a perfect replica of a Boeing 787 Dreamliner or a massive wind turbine blade. You wouldn't use the standard plastic bricks. You'd need something revolutionary: bricks that are incredibly strong, unbelievably light, and resistant to extreme temperatures and stress. In the world of advanced manufacturing, Hexcel makes those “magic bricks.” The company doesn't make airplanes or engines. It manufactures the underlying materials that make modern aerospace possible. These are called “advanced composites.” The most famous is carbon fiber, a material woven from microscopic strands of carbon that, when combined with special resins, creates a finished product with superhuman properties. Hexcel's business can be broken down into three main areas:

• Commercial Aerospace (The Engine Room): This is Hexcel's largest and most important segment. It supplies vast quantities of composite materials to giants like Boeing and Airbus. The new generation of fuel-efficient jets, like the Airbus A350 and the Boeing 787, are made of over 50% composite materials by weight, largely to reduce fuel burn. Hexcel is a critical, deeply integrated partner in this supply chain.
• Space & Defense (The Fortress): Hexcel also provides advanced materials for military applications. This includes fighter jets like the F-35, military helicopters like the Black Hawk, and various rockets and satellites. This segment is less cyclical than commercial aerospace, providing a valuable source of stability.
• Industrial (The Growth Bet): This is where Hexcel applies its technology to other industries. The most significant application is in wind turbine blades, which need to be increasingly long, strong, and light to capture more energy. It also serves high-end automotive and other industrial markets.

At its core, Hexcel is a high-tech manufacturing company whose success is tied to the global demand for things that need to be both incredibly strong and incredibly light.

“The best businesses are the ones that have a moat around them. And the wider the moat, the better.” - Warren Buffett ¹⁾

For a value investor, a company like Hexcel presents a fascinating case study in weighing a high-quality business against significant, unavoidable risks. It's a classic example of a “great company” that is only a “great investment” at the right price. Here's how a value investor would break down the investment case:

• The Formidable Economic Moat: Hexcel's primary appeal is its wide and deep economic_moat. This moat isn't built of castles and water, but of something far more powerful in the 21st century: certification and trust.
  • High Switching Costs: Before a single Hexcel part can fly on an Airbus A350, it must go through years of rigorous testing and certification by aviation authorities like the FAA and EASA. Once Hexcel is “spec'd in” to an aircraft design, it is almost impossible for an airline manufacturer to switch to a different supplier. Doing so would require a hugely expensive and time-consuming re-certification process. This locks in Hexcel's business for the entire multi-decade lifespan of an aircraft program.
  • Intangible Assets: Decades of proprietary knowledge in material science create a technological barrier that is extremely difficult for a new competitor to overcome. You can't simply decide to start making aerospace-grade carbon fiber tomorrow.
• Powerful Long-Term Tailwinds: The world wants to fly more, and it wants to do so more efficiently. This is a simple, powerful trend that directly benefits Hexcel. Every time an airline replaces an old aluminum-heavy plane with a new composite-heavy one, it's a win for Hexcel. This demand for lightweighting extends to wind energy and other industrial applications, providing future growth avenues.
• The Cyclical Trap: This is the big, flashing warning sign. Hexcel's fortunes are directly tied to the number of new planes Boeing and Airbus produce. The aerospace industry is notoriously cyclical, prone to booms and busts driven by economic growth, fuel prices, and geopolitical shocks. When airlines stop buying planes (as they did during the 2008 financial crisis and the 2020 pandemic), the pain flows directly down the supply chain to Hexcel. A value investor must acknowledge this cyclicality and demand a price that compensates them for this risk. This is not a “buy and forget” stock; it's a “buy when there's blood in the streets” stock.
• Understanding Mr. Market: The cyclical nature of Hexcel makes it a perfect illustration of Benjamin Graham's mr_market allegory. When aerospace is booming, the market becomes euphoric and prices Hexcel for permanent blue skies. When a crisis hits, Mr. Market panics and offers to sell you shares at a ridiculously low price, assuming planes will never fly again. The rational investor's job is to ignore this manic-depressive behavior and use his panics to their advantage.

Analyzing Hexcel is less about complex financial modeling and more about understanding the physical world of airplane manufacturing. You need to become a “supply chain detective.”

An investor should track these metrics to gauge the health and future prospects of Hexcel's business.

A compelling investment case for Hexcel from a value investing perspective would look something like this:

1. Step 1: Confirm the Moat. Analyze the company's position with Boeing and Airbus. Is its content on new, long-life aircraft programs secure? Yes. The moat is intact.
2. Step 2: Assess the Cycle. Where are we in the aerospace cycle? Are build rates near a peak or in a trough? Are airlines profitable and ordering new planes, or are they in crisis mode? The goal is to buy in the trough.
3. Step 3: Check the Financial Health. Is the balance sheet strong enough to survive a deep and prolonged downturn? Look for low debt levels and a history of prudent capital_allocation.
4. Step 4: Calculate Intrinsic Value. Using a conservative estimate of future free cash flows (perhaps by averaging earnings over a full cycle), determine what the business is fundamentally worth. Learn more.
5. Step 5: Demand a Margin of Safety. Because of the inherent cyclicality and unpredictability, an investor should demand to buy the stock at a significant discount (e.g., 40-50%) to their estimate of its intrinsic_value. This discount is your protection against being wrong or another unexpected crisis.

There is no better real-world example of the Hexcel investment thesis than the COVID-19 pandemic.

In late 2019, the aerospace industry was flying high.

• Air travel was booming.
• Boeing and Airbus had record backlogs stretching out for nearly a decade.
• Hexcel's revenues and stock price were near all-time highs.
• Mr. Market was euphoric, pricing Hexcel as if this perfect growth would continue forever. The stock traded at over $80 per share.

Then, in March 2020, the world stopped.

• Air travel evaporated almost overnight.
• Airlines parked their fleets and cancelled or deferred orders for new planes.
• Boeing and Airbus slashed their production rates dramatically.
• Hexcel's revenue plummeted, and the company was forced to lay off a significant portion of its workforce.
• Mr. Market panicked. The stock price crashed by over 60%, falling below $30 per share. The assumption was that the industry was permanently impaired.

A value investor looking at this situation would ask: “Has the long-term thesis changed?”

• The Moat: Was Hexcel's certified position on the A350 and 787 threatened? No.
• The Long-Term Trend: Would people eventually want to fly again? Almost certainly. Would airlines still need more fuel-efficient planes when they did? Yes, even more so.
• The Business Quality: The company was still a technological leader with a strong balance sheet.

The price of the business had fallen dramatically, but the fundamental quality and long-term prospects of the business itself were largely unchanged. The pandemic provided a textbook, albeit terrifying, opportunity to buy a wonderful business at a fair, or even wonderful, price, fully embracing the principle of margin_of_safety. Those who did were handsomely rewarded as air travel, and Hexcel's stock, recovered.

No investment is without risk. A prudent investor must weigh the potential upside against the potential downside.

• Wide Economic Moat: Extremely high switching costs and regulatory hurdles protect Hexcel's core business from competition.
• Secular Growth Tailwinds: The multi-decade global shift towards lighter, stronger, and more fuel-efficient aircraft provides a powerful tailwind for demand.
• Pricing Power: As a critical and sole-source supplier on many components, Hexcel has a degree of pricing power that can help it offset inflation.
• Growing Diversification: The Space & Defense segment offers stability, while the Industrial segment, particularly wind energy, offers a significant new avenue for long-term growth.

• Severe Cyclicality: The company's health is almost entirely dependent on the commercial aerospace cycle. An economic recession or another black swan event like a pandemic can devastate its earnings.
• Customer Concentration: An overwhelming portion of revenue comes from just two customers: Boeing and Airbus. Any production problems, design flaws, or strategic shifts at either of these giants will have an immediate and outsized impact on Hexcel.
• Capital Intensity: Operating and expanding manufacturing facilities for advanced composites is very expensive, which can be a drain on free cash flow, especially during downturns.
• Paying for Quality: The market often recognizes Hexcel's quality, meaning the stock frequently trades at a premium valuation. It is a common mistake to overpay for the company at the peak of the cycle, which can lead to years of poor returns.
