Howmet Aerospace – Precision Engineered for the Aerospace Supercycle

Howmet Aerospace Inc. was formed in 2020 following the split of Arconic into two entities: Howmet (focused on aerospace) and Arconic Corporation (focused on aluminum rolled products). Headquartered in Pittsburgh, PA, Howmet designs and manufactures advanced engineered products for the aerospace and defense industries. The company operates through four segments: Engine Products (investment castings, rotating parts, and structural components for jet engines), Engineered Structures (aerospace fasteners, titanium structures, and aluminum products), Forged Wheels (commercial transportation wheels), and Fastening Systems (aerospace fasteners and installation tools).

The company's primary customers include all major engine OEMs (GE Aerospace, Pratt & Whitney, Rolls-Royce, Safran) and airframe manufacturers (Boeing, Airbus, Lockheed Martin). Howmet generates revenue through two primary channels: original equipment (OE) sales to manufacturers and aftermarket sales of replacement parts and services to airlines and MRO providers. With approximately 23,000 employees globally and manufacturing facilities across North America, Europe, and Asia, Howmet serves as a critical node in the aerospace supply chain.

• Near-Term (12-24 months): Commercial aerospace production rate increases for the LEAP and GTF engines remain the primary growth catalyst. Boeing's 737 MAX production is recovering toward 50 aircraft per month, and Airbus is targeting 75 A320neo family deliveries per month by 2027. Each increase directly translates to incremental demand for Howmet's engine components. Additionally, the widebody recovery (787, A350, 777X) is expected to accelerate as international travel fully normalizes.

• Medium-Term (3-5 years): The emergence of the next generation of engine programs (RISE, CFM's open-fan architecture, and Pratt's GTF Advantage) will require significant new content from Howmet. Defense spending growth, particularly for F-35 procurement and next-generation fighter programs, provides a complementary growth stream. Management has guided to a mid-teens revenue CAGR over this period, with EBITDA margins expanding by 200-300 basis points.

• Aftermarket Acceleration: As the global installed engine fleet ages and utilization rates remain high, the aftermarket is growing faster than OE. Howmet's aftermarket revenue grew 25%+ in the most recent quarter, and this trend is expected to persist as airlines defer retirements and extend service intervals.

Note: 2023-2024 figures based on reported results; 2025-2027 are consensus analyst estimates.

Howmet's financial profile is characterized by strong revenue growth, driven by both volume increases and favorable pricing. The company has successfully passed through raw material costs while expanding its own margins through operational efficiency and mix shift toward higher-margin aftermarket sales. Free cash flow conversion has improved significantly, with management targeting over 100% conversion of adjusted net income.

The balance sheet is investment-grade, with net leverage of approximately 1.5x EBITDA. Management has committed to returning excess capital to shareholders through a combination of dividends and buybacks, with a target of returning 50-60% of free cash flow to shareholders annually.

The global aerospace components market is valued at approximately $150 billion, with the engine components and castings segment representing roughly $25 billion. This market is expected to grow at a 6-8% CAGR over the next decade, driven by commercial fleet expansion (global fleet projected to double to ~48,000 aircraft by 2042) and increasing defense budgets.

Howmet's competitive positioning is exceptionally strong due to several factors: (1) proprietary metallurgy and casting technologies developed over decades, (2) FAA and international certification requirements that make qualification of new suppliers a 3-5 year process, (3) long-term supply agreements with all major engine OEMs, and (4) scale advantages in a capital-intensive manufacturing process.

Key Competitors:

DCF Analysis: Applying a 10% WACC and 3% terminal growth rate to projected free cash flows yields a fair value of approximately $265 per share, implying roughly 15% upside from the current price. Key sensitivities: a 100bps increase in WACC reduces fair value to ~$235; a 1% decrease in terminal growth reduces fair value to ~$245.

Comparable Company Multiples:

Howmet trades at a premium to most aerospace suppliers on an earnings basis, reflecting its superior growth profile and market position. However, on an EV/EBITDA basis, the stock is more reasonably valued relative to TransDigm. The current P/E of ~51.7x on trailing earnings and ~57x on 2026E earnings embeds significant growth expectations, leaving limited room for execution missteps.

• Commercial Aerospace Downturn: A recession or geopolitical event causing a sharp decline in air travel would reduce both OE demand and aftermarket volumes. HWM's revenue is highly correlated with global RPMs (revenue passenger miles), and a 10% decline in traffic could reduce revenue by 8-10%.

• Boeing 737 MAX Production Issues: Howmet is a significant supplier to Boeing's MAX program. Any further production halts, quality issues, or regulatory actions that delay deliveries would directly impact HWM's near-term revenue. Boeing's ongoing challenges have already created volatility in the supply chain.

• Concentration Risk: The company's top 10 customers account for over 70% of revenue. Loss of a major program or customer dispute could have outsized impact. Additionally, any shift in engine platform preferences (e.g., Airbus moving away from LEAP) would require time to rebalance.

• Raw Material Volatility: Nickel, titanium, and cobalt are critical inputs. While the company has pass-through clauses, there is typically a 6-12 month lag. Sustained spikes in commodity prices could compress near-term margins.

• Execution Risk on Capacity Expansion: To meet growing demand, Howmet is investing significantly in capacity expansion. Any delays in bringing new capacity online or cost overruns could pressure both revenue growth and margins.
