• Industrial and IGT Outperformance: IGT and oil & gas revenues rose 25%+, highlighting HWM’s exposure to secular power infrastructure demand.
• Commercial Transportation Drag: Wheels volumes declined sharply, yet margin discipline held, mitigating the impact of end-market softness.

Free cash flow reached a record $344 million, supporting $175 million in buybacks and a 20% dividend increase, while net debt to EBITDA fell to a record low of 1.3x. Capex intensity remains elevated, with 70% of first-half spend targeting engine and IGT capacity, positioning HWM for sustained growth.

Executive Commentary

Strategic Positioning

1. Mix Shift to Spares and Aftermarket Drives Margin Expansion

Spares now comprise 20% of revenue, up from 11% in 2019, reflecting an intentional pivot toward higher-margin aftermarket business. This mix shift is structurally raising profitability, as spares and service revenue typically command better margins and more resilient demand than OEM (original equipment manufacturer) sales. Management emphasized that spares for commercial and defense aerospace, IGT, and oil & gas grew 40% year-over-year, and this trend is expected to persist as installed fleets age and utilization rises.

2. Capacity Buildout Anchors Multi-Year Growth Trajectory

HWM is in the midst of a significant capacity expansion program, with two new plants and two major extensions underway across engine and IGT segments. These investments, heavily weighted to turbine airfoils and large gas turbines, are expected to begin contributing in late 2025 and ramp into 2026-2027. While headcount additions and upfront costs are creating short-term margin drag, management is clear that these are necessary to capture secular growth in aerospace and power infrastructure. Notably, new capacity is being built with a focus on automation and efficiency, setting the stage for future productivity gains.

3. Capital Allocation Remains Disciplined and Opportunistic

HWM continues to balance aggressive organic investment with shareholder returns. The company repurchased $175 million in shares during the quarter (and $100 million more in July), raised the dividend by 20%, and paid down $76 million in debt, all while maintaining ample liquidity and a conservative leverage profile. Management reiterated that organic growth remains the highest-return use of capital, but buybacks and dividends will remain a priority as free cash flow expands.

4. Operational Flexibility Mitigates End-Market Volatility

Despite a challenging backdrop in commercial transportation, HWM flexed costs and preserved margins in wheels and fasteners. The company’s ability to rapidly adjust headcount and rationalize product lines, as seen in the Engineered Structures segment, has enabled it to maintain profitability even as certain markets soften. This operational agility is a key competitive advantage as supply chain and demand conditions remain fluid.

5. Industry Bottlenecks and Strategic Assets Enhance Competitive Moat

HWM’s ownership of two of the four US forging presses over 35,000 tons, along with its expanding spares and IGT footprint, positions the company as a critical supplier in both aerospace and defense. Management acknowledged that these unique assets are likely to become more valuable as industry bottlenecks and policy priorities intensify, particularly in defense and energy transition applications.

Key Considerations

HWM’s Q2 results highlight a business in transition, leveraging secular tailwinds in aerospace, defense, and power generation while actively managing cyclical and operational headwinds. The company’s focus on mix, margin, and capital discipline is reshaping its earnings power and risk profile.

Key Considerations:

• Aftermarket Mix Drives Resilience: Growing share of high-margin spares and services creates a buffer against OEM and transportation volatility.
• Capex Cycle Elevates Near-Term Spend: Heavy investment in new plants and automation will pressure free cash flow conversion until 2027, but underpins future growth.
• Headcount Ramp as Leading Indicator: Net additions of 400+ in Q2 (and 860 YTD in Engines) signal a strategic bet on demand acceleration, with near-term training costs offset by volume leverage.
• Tariff and Metal Cost Recovery Remain a Watchpoint: Delayed pass-throughs, especially in Fasteners, could create short-term margin noise, though management expects improvement as the year progresses.
• Industry Asset Scarcity: HWM’s unique forging assets and capacity expansions may yield pricing and volume upside as bottlenecks persist across aerospace and defense supply chains.

Risks

Risks center on execution of the capacity ramp, supply chain bottlenecks at OEMs (notably engine shortages for Airbus and Boeing), and the pace of commercial transportation recovery. Tariff and commodity pass-through timing could introduce margin volatility, and elevated capex raises the bar for return on invested capital. Management’s ability to convert backlog into profitable growth amid these crosscurrents will be critical.

Forward Outlook

For Q3 2025, HWM guided to:

• Revenue of $2.03 billion, plus or minus $10 million
• EBITDA of $580 million, plus or minus $5 million
• EPS of $0.90, plus or minus $0.01

For full-year 2025, management raised guidance:

• Revenue: $8.13 billion, plus or minus $50 million
• EBITDA: $2.32 billion, plus or minus $20 million
• EPS: $3.60, plus or minus $0.04
• Free cash flow: $1.225 billion, plus or minus $50 million

Management highlighted:

• Increased spares expectations and higher Boeing 737 MAX production underpinning revenue outlook
• Capex guidance raised to support future growth, with modest benefit from new tax legislation

Takeaways

HWM is executing a deliberate margin and mix transformation, leveraging secular demand in aerospace and industrial power to drive record profitability and free cash flow.

• Margin Expansion as Structural, Not Cyclical: Mix shift to spares and IGT, coupled with operational discipline, is driving sustainable margin gains.
