Why ATI (ATI) Is Emerging as an Aerospace Supply Chain Winner

Polen Capital Management Llc released its “Polen Focus Growth Strategy” Q2 2026 investor letter. A copy of the letter can be downloaded here. Polen Focus Growth returned 6.33% (net of fees) in the second quarter of 2026, significantly underperforming the Russell 1000 Growth Index’s 16.74% gain, as the market rally remained narrowly focused on AI infrastructure and semiconductor stocks. During the quarter, Polen Capital repositioned the portfolio toward companies benefiting from structural growth in AI infrastructure, power demand, and aerospace. Looking ahead, the managers remain confident in the long-term earnings potential of the portfolio but acknowledge that changing market dynamics and the rising opportunity cost of patience require a more nimble approach. They remain focused on competitively advantaged businesses with durable growth prospects, while selectively participating in AI infrastructure, commercial aerospace, and power infrastructure opportunities where supply constraints and long-term demand could support sustained earnings growth.

Polen Focus Growth Strategy stated the following regarding ATI Inc. (NYSE:ATI)  in its Q2 2026 investor letter:

We initiated a new position in ATI Inc. (NYSE:ATI), a leading producer of specialty materials, including nickel-based alloys used in high-temperature jet engine components. While this may not sound like a traditional Focus Growth investment at first glance, we believe the world has changed meaningfully for ATI. The aerospace supply chain is structurally constrained, and ATI is one of only a very small number of companies capable of producing these materials at the required scale and quality. Our research suggests capacity additions appear limited, while demand from commercial aerospace and gas turbines should remain strong for many years. In our view, ATI is an example of a business that historically may have appeared more cyclical or commodity-like, but where industry structure, scarcity value, and end-market demand have improved significantly.
