Broad-Based Growth Drivers Lifted ATI (ATI) in Q4

Carillon Tower Advisers, an investment management company, released its fourth-quarter 2025 investor letter for the “Carillon Scout Mid Cap Fund”. A copy of the letter can be downloaded here. Major U.S. equity indices delivered positive returns in the fourth quarter, while the Russell Midcap® Index return lagged with nominal positive gains. Strong corporate earnings revisions and lower short-term interest rates supported U.S. market returns. Investors’ focus on an optimistic 2026, and consensus outperformed the market amid long-term government shutdowns. High sector return dispersion was observed in the Russell Midcap Index, with healthcare, materials, and IT leading. However, investors’ bias towards higher beta and more cyclical stocks led Communication services, real estate, and utilities to lag in the quarter.  The fund expects the Midcap equities to trade higher in 2026, supported by broader market involvement, though this view aligns with consensus. U.S. market index earnings are projected to grow significantly in 2026 despite price-to-earnings ratios being higher than historical averages.  Please review the Fund’s top five holdings to gain insights into their key selections for 2025.

Carillon Scout Mid Cap Fund stated the following regarding ATI Inc. (NYSE:ATI) in its fourth quarter 2025 investor letter:

“ATI Inc. (NYSE:ATI) is a specialty materials company that makes high-performance metals and alloys. The company recently exited its commoditized metals business and increased its exposure to higher-margin nickel and titanium alloys. Sales to the aerospace industry now account for more than two-thirds of total revenue, up from less than half just four years ago. An increasing aerospace production outlook, new business awards from a major airplane manufacturer, improved execution, and a focus on more value-added engine and airframe parts has boosted investor interest. An opportunity in nuclear energy is also emerging. We believe ATI should trade more in line with other aerospace parts suppliers as the company proves it can produce more consistent revenue growth at higher margins.”
