The Thesis
Howmet Aerospace is an aerospace component manufacturer that makes the high-performance parts that allow jet engines to operate at extreme temperatures. The company generated $7.43 billion in revenue last year, a 12% increase over the prior year, as global air travel demand reached new heights. The structural shift that makes the growth story possible is the simultaneous ramp-up of next-generation engine production and the extended lifespan of older aircraft which drives high-margin spare parts sales.
If you own HWM, you're betting on four specific outcomes.
We think Howmet Aerospace is a high-quality compounder, but the stock is currently priced for perfection after a significant run. The business is firing on all cylinders with revenue growth accelerating to 19% in the most recent quarter. However, the current valuation assumes this exceptional pace continues without a hitch for several years. For long-term investors, the case for holding remains strong, though new buyers may want to wait for a more reasonable entry point.
Numbers at a Glance
What does it do?
Howmet Aerospace is a mature business that earns money by designing and casting specialized metal parts for jet engines, airframes, and heavy trucks. Money flows into the company primarily from long-term contracts with engine makers like GE and Pratt & Whitney, as well as aircraft manufacturers like Boeing and Airbus. These customers pay Howmet because the company controls proprietary casting techniques and titanium alloys that can survive the intense heat and pressure inside a modern jet engine. Because these parts are flight-critical and often single-sourced, customers are locked into Howmet's ecosystem for the entire 20 to 30 year life of an aircraft model.
Where does revenue come from?
The vast majority of revenue comes from the aerospace industry, specifically from components that sit inside the hottest parts of jet engines. The Engine Products segment is the largest, providing airfoils and seamless rings that are essential for propulsion. Fastening Systems provides specialized aerospace bolts and rivets that hold planes together, while Engineered Structures produces titanium parts for airframes and defense applications. A smaller portion of revenue comes from Forged Wheels, which sells aluminum wheels to the heavy-duty truck market.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Howmet Aerospace serves the world's largest aerospace manufacturers and engine builders including Boeing, Airbus, GE, and Rolls-Royce. While the company does not disclose a single total customer count, its business is highly concentrated among these global giants who dominate the aviation supply chain. In the most recent year, aerospace and defense customers accounted for approximately 85% of total revenue. Because Howmet is a Tier 1 supplier, its revenue is directly tied to the monthly production rates of aircraft like the Boeing 737 MAX and the Airbus A320neo family.
What gives it staying power?
Howmet's staying power comes from its dominant position in high-temperature investment casting, a process so difficult that only one or two companies in the world can do it at scale. The switching costs are massive because every part must be certified by aviation regulators: changing a supplier can take years and millions of dollars in testing.
Where is it headed?
The company is focused on capturing the massive backlog of next-generation aircraft orders while squeezing more profit out of its existing factories. Management is betting that the transition to more fuel-efficient engines will require even more of their specialized, high-value components. If production rates at the major aircraft builders normalize, Howmet stands to benefit from significant operational efficiencies.
Revenue growth is accelerating as the aerospace supply chain finally clears its post-pandemic hurdles. Revenue hit $2.31 billion in the latest quarter, marking a 19% increase that outpaces the 12% growth seen over the full prior year. This trend suggests the company is moving into a period of higher production volume.
Cash flow is strong and increasingly used to reward shareholders through aggressive buybacks. The company generated $1.43 billion in free cash flow in the most recently reported year, which comfortably covers its capital needs. This cash quality allows management to consistently reduce the share count, which helps boost earnings per share faster than revenue.
The balance sheet is managed conservatively with a debt-to-equity ratio of 0.85x. Howmet carries $3.46 billion in total debt, but its high cash generation and 33% return on equity provide a massive buffer. The financial structure is built to withstand the typical cyclical swings of the aerospace industry.
Howmet is a financially exceptional business that is currently seeing its best margins and growth in years.
Profit margins are expanding rapidly because the company is producing more parts without needing to add significant new overhead. In the most recent quarter, net income grew nearly four times faster than revenue. This happens because Howmet’s specialized casting plants are highly efficient when running at full capacity.
Aircraft build rates at Boeing and Airbus remain the single biggest bottleneck for Howmet's growth. If technical issues or labor strikes further delay aircraft deliveries, Howmet will be forced to slow down its own production lines. Management has proven they can manage through these delays, but a prolonged slump would eventually hurt the stock.
The aerospace component market is a multibillion-dollar industry currently valued at roughly $100 billion and is expected to grow as the global fleet expands and modernizes. Pricing power is structural here because the parts Howmet makes are mission-critical and highly regulated, making them difficult to commoditize. Howmet is a dominant leader in the engine components niche, sitting in a "toll booth" position where nearly every commercial jet engine produced requires their specialized parts to function.
The aerospace supply chain is a rationally structured market where high barriers to entry prevent new players from appearing overnight. Competition is based on technical capability and certification rather than just price, which protects long-term margins for the top players.
Precision Castparts is the most direct threat, as they are the only other player with comparable scale in high-temperature casting technology. ATI competes for structural titanium business, while Lisi Aerospace challenges Howmet in the fastener market, but neither has the same breadth across the engine core. Precision Castparts remains the formidable rival because its backing by Berkshire Hathaway allows it to take a very long-term view on pricing and capacity.
Howmet is currently gaining ground and holding pricing power as evidenced by its expanding net margins of 20.2%.
The primary source of protection is a combination of intellectual property and massive switching costs. Howmet owns proprietary casting processes for single-crystal airfoils that can operate in temperatures higher than their own melting point. A customer cannot switch to a cheaper part without re-certifying the entire engine with the FAA, a process that takes years.
The numbers tell a clear story of a durable competitive advantage. A 17.3% return on invested capital combined with a 33% return on equity proves that Howmet is not just a manufacturer, but a high-value technology provider. These are not typical "metal bending" margins; they reflect a structural edge that competitors cannot easily replicate.
The moat is strengthening as engine designs become more complex, requiring the extreme precision that only Howmet can provide at scale.

Capital Allocation Track Record
John C. Plant is widely regarded as one of the best operational leaders in the industrial sector. His focus on stripping out costs while investing in the most difficult-to-make parts has transformed Howmet from a sluggish manufacturer into a high-margin growth engine. He has consistently delivered on margin targets and has been a disciplined steward of capital, favoring share buybacks over risky or expensive acquisitions.
