Howmet Aerospace's Strategic Position in the 737 Max Supply Chain: A Lucrative Bet on Aerospace Recovery?

The aerospace industry's post-pandemic rebound has been one of the most compelling stories in global manufacturing. At the center of this revival is Boeing's 737 Max, a narrow-body aircraft whose production ramp-up is reshaping supply chains and boosting demand for specialized components. For Howmet Aerospace (HWM), a leading supplier of fasteners, engine parts, and aerospace systems, this dynamic presents a unique opportunity—and a test of strategic resilience.

Strategic Supply Chain Positioning: A Win-Win with Boeing

Howmet's alignment with the 737 Max program is no accident. The company is a critical supplier of fastening systems and engine components, including turbine blades and high-pressure compressors, which are essential for the aircraft's performance and efficiency. With Boeing delivering 206 737 Max units in the first half of 2025—up from 135 in the same period the prior year—Howmet has directly benefited from the production surge.

The company's second-quarter 2025 results underscore this alignment. Revenue rose 9.2% year-over-year to $2.05 billion, with commercial aerospace sales up 8%. Its Engine Products segment, which includes 737 Max components, generated $1.1 billion in revenue, a 13% increase, while its Fastening Systems segment grew by 9%. These figures reflect Howmet's dual advantage: it supplies both the structural and propulsion systems of the 737 Max, ensuring recurring revenue across production and maintenance cycles.

Earnings Visibility: A Post-Pandemic Tailwind

The 737 Max's production ramp-up has provided Howmet with a rare level of earnings visibility. With Boeing projecting a build rate of 38 units per month in the second half of 2025 and potentially 42 units by year-end, Howmet has raised its full-year revenue forecast to $8.08–$8.18 billion, up from $7.88–$8.18 billion earlier this year. This optimism is further fueled by the growing demand for spares, as airlines extend the lifespan of older aircraft due to lingering supply chain bottlenecks.

Howmet's margins are also strengthening. The Engine Products segment reported a 20% year-over-year increase in Adjusted EBITDA to $349 million in Q2 2025, driven by higher volumes and pricing discipline. The company has mitigated cost pressures from U.S. tariffs on aluminum and steel by passing on price hikes to customers, a strategy that has preserved profitability while maintaining customer relationships.

Historically, Howmet's earnings beats have shown a positive market response. From 2022 to the present, the company has exceeded expectations 9 times, with a 66.67% win rate over three days and an average return of 1.14% in the short term. This pattern suggests that the market has historically rewarded Howmet's operational execution, even amid sector volatility.

Navigating Risks: A Cautious Optimism

Despite the positive trajectory, Howmet's leadership has adopted a cautious stance. CEO John Plant has tempered expectations, assuming a 737 Max production rate of 25 units per month in 2025—lower than Boeing's internal targets—due to uncertainties around inventory drawdowns and supply chain fragility. This conservatism is prudent: a fire at an SPS Technologies fastener plant and global inventory shortages have highlighted vulnerabilities in the aerospace supply chain.

Moreover, the company's reliance on Boeing exposes it to regulatory risks, particularly around the FAA's potential delays in lifting production caps on the 737 Max. However, Howmet's diversification into defense aerospace and industrial gas turbines provides a buffer, reducing overdependence on any single program.

Investment Thesis: A High-Conviction Play

For investors, Howmet offers a compelling case. Its strategic positioning in the 737 Max supply chain, combined with a robust balance sheet and strong cash flow generation, makes it a standout in the aerospace sector. The company's share repurchase program and debt reduction efforts further enhance shareholder value, while its capital expenditures—up 60% year-over-year—signal confidence in future demand.

However, risks remain. Supply chain disruptions, geopolitical trade tensions, and potential regulatory headwinds could dampen growth. Investors should monitor Boeing's production cadence and Howmet's ability to manage input costs.

Conclusion: A Long-Term Bet on Aerospace's Resurgence

Howmet's strategic alignment with the 737 Max program positions it as a key beneficiary of the post-pandemic aerospace recovery. While near-term challenges persist, the company's financial discipline, operational flexibility, and critical role in Boeing's production pipeline make it a high-conviction investment. For those with a long-term horizon, HWM offers exposure to a sector poised for sustained growth, provided management continues to balance caution with ambition.

Investment Recommendation: Buy. Howmet's earnings visibility, margin resilience, and strategic positioning justify a premium valuation. Investors should target entry points during short-term volatility, particularly if broader aerospace sector indices correct.
