Summary

  • Commercial Aero Spares Demand: Aftermarket parts sales soared, driving record segment profitability and cash generation.
  • CapEx and Expansion: Capital deployment is accelerating to support engine and turbine capacity, with investment tightly linked to customer contracts.
  • Margin and Cash Flow Strength: Operational leverage and productivity gains are translating into record margins, supporting aggressive buybacks and dividend growth.

Performance Analysis

HWM posted a standout quarter, with revenue up 14% year over year, but the more material signal was the rapid acceleration in commercial aerospace spares, up 38%, and defense engine spares, up 33%, which together drove a 31% overall spares increase. EBITDA growth of 26% and a 290 basis point margin expansion to 29.4% highlighted strong operational leverage, even as the company absorbed costs from 265 net headcount additions—mainly in the high-growth engines business.

Free cash flow reached $423 million after $108 million in capital expenditures, reflecting disciplined investment and robust working capital management. Share buybacks accelerated, with $600 million repurchased year-to-date through October, already exceeding last year’s total. Net leverage fell to a record low 1.1x EBITDA, and S&P upgraded HWM’s credit rating to BBB+, further solidifying its capital position. Segment results were uniformly strong: Engines revenue grew 17%, Fastening Systems 14%, and Engineered Structures 14%, with each segment delivering margin expansion despite inflation and labor investment.

  • Aftermarket Upside: Spares demand across commercial and defense aerospace, IGT, and oil and gas collectively rose 31%, underpinning margin strength.
  • Segment Outperformance: Engines EBITDA margin hit 33.3%, Fastening Systems 30.8%, and Engineered Structures 20.1%—each outpacing revenue growth.
  • Cash Deployment: Buybacks and dividends accelerated alongside capital investment, with $770 million deployed year-to-date on shareholder returns and debt paydown.

Commercial transportation remains a drag, with volumes down 16% and segment revenue down 3%, but this was more than offset by strength in aerospace and industrial markets. Tariff pass-through and commodity volatility continue to impact transportation margins, though the net effect remains manageable at under $5 million for the year.

Executive Commentary

"Q3 was a very strong quarter for Hamad. Revenue growth continues to accelerate and was at 14% compared to 8% in the first half. Within this revenue growth, commercial aerospace increased 15%. And within this number, commercial aero parts sales increased by 38% for a total spares increase of 31%. EBITDA was up 26% and operating income up 29%. Cash flow was also healthy at $423 million after capital expenditure of $108 million."

John Plant, Executive Chairman and Chief Executive Officer

"The balance sheet continues to strengthen. Free cash flow was excellent at $423 million. Free cash flow included the acceleration of capital expenditures with $108 million invested in the quarter and approximately $330 million year-to-date, which is higher than the full-year 2024 capital expenditures. About 70% of the capital expenditures year-to-date is for our engines business as we continue to invest for growth in commercial aerospace and IGT. Investments are backed by customer contracts."

Strategic Positioning

1. Aerospace Aftermarket as Growth Engine

The commercial and defense aerospace aftermarket is now the company’s primary profit driver, with spares sales outpacing original equipment (OE) growth. Management expects this dynamic to persist for at least five years, as aging fleets and high utilization drive demand for engine parts—especially turbine blades in the hot gas path. This shift supports both margin expansion and resilience against OE production volatility.

2. Capital Investment in Engines and Turbines

HWM is aggressively investing in new manufacturing capacity, particularly for engine cores and advanced casting for both aerospace and industrial gas turbines (IGT). The Michigan aero engine plant and expanded European and US facilities are on track, with CapEx running at record levels. Management links these investments directly to customer-backed contracts, mitigating risk and ensuring high returns on capital deployed.

3. Diversification into Data Center Power Infrastructure

Demand for midsize and large industrial gas turbines is surging, fueled by data center expansion and the need for reliable, fast-reacting electricity supply. HWM is leveraging its aerospace materials and cooling technologies to win share in this secular growth market, where utility and data center customers require advanced, high-temperature turbine blades. The company expects this segment to grow at double-digit rates, with economics on par with aerospace.

4. Productivity and Digital Transformation

Automation, AI, and the “digital thread” are central to HWM’s next phase of margin improvement. Management is building data infrastructure to track manufacturing from chemical compounding through casting, enabling yield gains and tighter tolerances. AI-driven analytics are expected to unlock further efficiency and content gains, setting the stage for the next generation of product and margin expansion.

5. Capital Returns and Balance Sheet Strength

With net leverage at 1.1x and a BBB+ credit rating, HWM is deploying capital across buybacks, dividends, and expansion. Share count reduction and a 20% dividend hike reflect confidence in sustained free cash flow, even as CapEx rises. Management is signaling a bias toward growth investment, but not at the expense of shareholder returns or balance sheet flexibility.

Key Considerations

HWM’s Q3 results reflect a company leveraging secular tailwinds in aerospace and power infrastructure, while maintaining disciplined capital allocation and operational rigor. Investors should weigh:

Key Considerations:

  • Aftermarket Resilience: Spares demand is structurally high, supporting margins and cash flow through OE cycles.
  • CapEx-Backed Growth: Capital spending is tightly linked to customer demand, reducing risk of overbuild.
  • Labor and Productivity Tradeoffs: Headcount additions are a near-term drag, but productivity and automation gains are expected to offset costs as new plants ramp.
  • Transportation Weakness: Commercial transportation remains a drag, with volume and tariff uncertainty persisting—though now a smaller share of overall revenue.
  • Tariff Volatility: Tariff impacts have been managed down to a minimal level, but remain a watchpoint for the transportation segment.

Risks

Key risks include potential delays in customer turbine and engine build rates, which could impact capacity utilization and return on recent CapEx.
