Howmet Aerospace is an aerospace component manufacturer that produces the complex, high-performance parts engines and airframes require to fly. It generated $8.25 billion in revenue in 2025, representing 11% growth over the prior year. The company is currently operating at record levels of profitability as aircraft manufacturers race to clear massive order backlogs.
The investment thesis on Howmet Aerospace is that its specialized metallurgy and casting capabilities create a technical lock-in that competitors cannot replicate, even as production rates climb. While engine makers can choose different assembly partners, they cannot easily switch the suppliers of the advanced turbine blades and fasteners that Howmet produces.
We view Howmet as an exceptional business that is currently trading at a price that leaves no room for the inevitable bumps in the aerospace cycle. While the operational execution under John Plant is flawless, the stock has outpaced its fair value following a massive run.
Howmet Aerospace stock has soared over the last few years as the business reached record levels of success. Its shares are up roughly eight times since five years ago because aircraft makers are desperate for the specialized engine parts the company builds. Since competitors cannot easily copy this technology, demand remains high as airlines try to clear their massive backlog of new planes.
What does it do?
Howmet Aerospace is a mature industrial business that earns money by designing and manufacturing advanced engine components and specialized fasteners for the aerospace and defense sectors. It operates as a critical "tier 1" supplier, meaning it sells directly to engine makers like GE and aircraft manufacturers like Boeing and Airbus. The company’s core advantage lies in investment casting, a process used to create complex metal parts that can withstand the extreme heat and pressure of a jet engine. Customers pay for the precision and durability of these parts, which are often sole-sourced, meaning Howmet is the only qualified supplier for that specific component.
Where does revenue come from?
The majority of revenue is generated from the Engine Products segment, which produces the turbine blades and vanes found in modern jet engines. This segment accounted for roughly 45% of 2024 revenue. The remaining sales come from Fastening Systems (20%), Engineered Structures (15%), and Forged Wheels (20%). While most revenue is domestic, the company serves a global customer base including major European and Asian aerospace players.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Howmet Aerospace serves major aircraft manufacturers and engine makers, including a 17% revenue contribution from the high-margin engine spares market. The company does not disclose individual customer counts like a consumer business, but its primary clients are the handful of global aerospace giants that control the market. In 2024, engine spares reached $1.26 billion in revenue, a significant shift from 2019 levels. The company also supplies the defense sector, specifically for the F-35 fighter jet program, which saw 15% revenue growth in 2024.
What gives it staying power?
Howmet’s staying power comes from high switching costs and proprietary manufacturing processes that are nearly impossible for rivals to copy. Once a part is certified for a specific engine model, switching suppliers requires a multi-year re-certification process with regulators.
Where is it headed?
Management is pivoting the business toward the Industrial Gas Turbine (IGT) market to capture rising demand for electricity from AI data centers. This provides a new growth lever that uses the same casting technology as jet engines. If successful, this could reduce the company's dependence on the cyclical commercial aerospace market.
Verdict: The business is accelerating as it enters a period of record revenue and profitability. Revenue reached $8.25 billion in 2025, supported by double-digit growth in the core engine products segment. This growth is driven by a shift toward more complex, higher-priced components that carry better margins.
Verdict: Cash generation is exceptional, with free cash flow growing faster than net income. In 2025, free cash flow reached $1.43 billion, a significant jump from $0.68 billion just two years prior. This efficiency allows the company to fund its own capacity expansions while aggressively returning capital to shareholders.
Verdict: The balance sheet is in its strongest position in years, characterized by declining debt and rising credit ratings. Howmet reduced its debt by $282 million in a single quarter of 2024 and recently received a credit rating upgrade to BBB+ from Fitch. The net debt position is manageable given the business's high recurring cash flow from engine spares.
Howmet Aerospace is a financially elite industrial business that is currently hitting its stride in terms of both growth and margin expansion.
Profit margins have reached record highs, with the Engine Products segment delivering an adjusted EBITDA margin of 31.1%. This proves that the company has significant pricing power and can effectively spread its fixed manufacturing costs across higher production volumes.
The commercial transportation market remains soft, with Forged Wheels revenue under pressure from weak European market conditions. If the trucking industry does not recover by the second half of 2026, it could act as a persistent drag on the company's otherwise strong growth profile.
The aerospace and defense component market is a multibillion-dollar industry currently benefiting from record aircraft backlogs exceeding 13,000 units. The industry is growing roughly 8% annually and is on track to exceed $300 billion in market value by 2030. This is a structurally attractive industry because the safety-critical nature of the parts makes reliability more important than price. Howmet stands as a dominant leader in the engine casting niche, providing a long growth runway as airlines modernize their fleets with newer, more fuel-efficient engines.
The aerospace supply chain is rationally structured, with high barriers to entry and a small number of qualified suppliers for mission-critical parts. Entry by new competitors is restricted by the years of testing and regulatory certification required to fly a single part.
Howmet's most direct rival is Precision Castparts, which competes across nearly every casting and forging product line. TransDigm is a different kind of threat, often acquiring sole-source components and aggressively raising prices, which can sometimes compete for the same capital in customer budgets. The most dangerous threat is Precision Castparts, which has the backing of Berkshire Hathaway to invest through long industry cycles.
Howmet is currently gaining share in the high-growth engine spares market. This is evident in its spares revenue rising from 11% of total sales in 2019 to 17% in 2024. The company is successfully outgrowing its core markets by focusing on the most complex components.
The primary source of Howmet’s moat is the extremely high switching costs associated with engine components. Once a Howmet turbine blade is certified by the FAA as part of a specific engine design, it is almost never swapped for a competitor's part during the engine's 20-year life. This sole-source position creates a recurring revenue stream that is legally protected by safety certifications.
The financial data confirms this advantage, with ROIC reaching 17.3% and net margins exceeding 20%. These figures prove that Howmet is not competing on price but rather on the unique difficulty of its manufacturing process. The combination of high ROIC and expanding margins during a period of supply chain stress proves the moat is real.
The moat is strengthening as engine designs become more complex, requiring the advanced metallurgy that only a few companies in the world can handle.

Capital Allocation Track Record
John Plant is a high-caliber operator who has successfully transformed Howmet from a sluggish industrial conglomerate into a lean, high-margin aerospace specialist. His strategic judgment is evident in the decision to prioritize the Engine Products segment, which now delivers record profitability. Management has consistently hit or exceeded its own guidance, building deep credibility with shareholders by delivering on both margin expansion and capital returns.
The primary governance risk is the high degree of dependence on John Plant, whose leadership has been the central driver of the company's turnaround. While the company has a capable bench of segment presidents, the "Plant Playbook" of operational discipline is a specific management style that would be difficult to replace. There are no major board independence concerns, but the thesis would face a significant test if Plant were to step down unexpectedly.
We expect revenue to grow from $9.7B in FY2026 to $15.8B in FY2031 (~10% CAGR), with EPS growing from $5.06 to $10.52 (~16% CAGR). Demand for advanced engine components and aerospace fasteners is rising as aircraft manufacturers ramp up production to meet record backlogs. Specialized manufacturing facilities spread fixed overhead across higher production volumes of high-margin engine parts. EPS grows faster than revenue because expanding profit margins and share buybacks amplify the bottom-line impact of sales growth. Operating margin expected to reach ~34% by FY2031.
Engine spares reach 20% of total revenue mix. Increasing the mix of high-margin replacement parts would drive permanent margin expansion and insulate the business from aircraft build-rate volatility.
Industrial Gas Turbine demand scales for data centers. As AI workloads drive record electricity demand, Howmet can repurpose its aerospace casting expertise for lucrative ground-based power turbines.
F-35 program production ramp reaches full scale. A steady increase in global F-35 deliveries provides a multi-decade recurring revenue stream for airframe and engine components.
OEM production rates stall due to regulatory or labor issues. If major customers like Boeing face further production delays, Howmet’s "original equipment" revenue could fall faster than spares can compensate.
Raw material costs for specialized alloys spike sharply. A disruption in the supply of exotic metals like nickel or titanium would compress margins before Howmet can pass costs to customers.
A major global recession reduces air travel demand. While spares are defensive, a sharp drop in flight hours would reduce the wear-and-tear that drives the lucrative engine replacement cycle.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Forward P/E approach based on FY2027 earnings to calculate the fair value. This framework is appropriate because Howmet's earnings have reached a new structural plateau following the recovery in commercial aerospace and a strategic shift toward high-margin proprietary parts, making current earnings a reliable signal of future value.
Our projected FY2027 EPS of $6.02 multiplied by a 46x multiple results in a fair value of $277 per share. A 46x multiple sits just below high-quality aerospace peers TransDigm (50x) and Heico (48x), which is justified by Howmet's essential "bottleneck" status in jet engine supply chains. Our earnings basis of $6.02 is pulled directly from the deterministic projection for the 2027 fiscal year.
A 5-year Discounted Cash Flow (DCF) cross-check produces a fair value of $265—within 5% of our $277 Forward P/E result, confirming the valuation. This DCF (using a 10% discount rate and 3% terminal growth) assumes free cash flow grows at 15% annually, which is conservative compared to the 19% revenue growth and 168% free cash flow growth reported in Q1 2026. The two methods are in strong agreement, suggesting the stock is currently trading very close to its fundamental fair value.
We're assuming Howmet sustains a 32% Adjusted EBITDA margin through 2027. This matches the performance from the most recent quarter (Q1 2026) and is supported by a structural shift toward higher-margin engine spares and the integration of the high-value Consolidated Aerospace Manufacturing (CAM) acquisition.
We're assuming a 46x Forward P/E multiple is durable for a sole-source aerospace provider. While this is a high multiple for a traditional industrial company, Howmet’s monopoly-like position in specialized investment castings (complex metal parts) justifies a "quality premium" similar to high-performance peers like TransDigm or Heico.
We're assuming commercial aircraft build rates continue to recover toward pre-2020 levels by 2027. Recent news and market trends show an unprecedented aircraft build rate and a massive backlog, providing high visibility into the revenue stream for Howmet’s engine and fastening segments.
The biggest risk is a prolonged manufacturing slowdown at major aircraft manufacturers like Boeing or Airbus. This would choke off the volume growth required to sustain Howmet's premium 46x forward multiple, potentially knocking roughly $60 off the per-share fair value as the stock de-rates toward the broader industrial average. Watch monthly aircraft delivery data and OEM "stop-work" orders as the primary early signal.
Bear case ($215): Boeing or Airbus monthly deliveries drop below 45 aircraft for two consecutive quarters due to supply chain or safety pauses; or Adjusted EBITDA margins compress below 29% as labor costs outpace the pricing power of the commercial engine segment.
Bull case ($330): The $1.8 billion CAM acquisition delivers over $0.50 in EPS accretion by the end of 2027, exceeding management's "insignificant" 2026 forecast; or AI-driven data center demand leads to a 20%+ surge in backlog for industrial gas turbine components.

The market is betting on Howmet Aerospace because its unique metal casting technology is essential for the engines manufacturers are rushing to build. Aircraft makers currently face record backlogs and cannot fulfill their delivery schedules without Howmet’s specialized parts. This creates a technical lock-in that ensures Howmet remains the primary partner for critical engine components as production volume hits peak levels.
Skeptics think that Howmet is becoming too reliant on the delivery schedules of just two major aircraft manufacturers. If these manufacturers continue to struggle with their own supply chain or quality delays, Howmet will see its growth stall regardless of how high its internal production efficiency reaches.
