ATI delivered a strong finish to 2025, exceeding profit and free cash flow expectations with Q4 revenue of $1.2 billion and Adjusted EBITDA of $232 million, a 19.7% margin. For the full year, revenue reached $4.6 billion (up 5% YoY), driven by 14% growth in aerospace and defense, while Adjusted EBITDA grew 18% to $859 million. Adjusted EPS surged 32% to $3.24, and Adjusted Free Cash Flow increased 53% to $380 million. The company returned $470 million to shareholders, representing 124% of FCF. Looking ahead, ATI issued confident 2026 guidance targeting $1 billion in Adjusted EBITDA at the midpoint (16% growth) and $460 million in FCF, fueled by accelerating demand in aerospace, robust defense spending, and expanding specialty energy markets.

Aerospace & Defense (A&D) dominance is solidifying, with the segment now comprising 68% of total revenue, up from 62% in 2024. Management reported 14% A&D growth for the year, including a 21% surge in jet engine sales and 14% growth in defense. This shift toward higher-value, proprietary markets is a key driver of margin expansion, with full-year adjusted EBITDA margins reaching 18.7%. The company expects A&D to represent over 70% of sales in 2026, further de-risking the portfolio and enhancing pricing power.
ATI is aggressively expanding its 'moat' by producing six of the seven most advanced jet engine nickel alloys, securing proprietary content in next-generation engines. This strategy is supported by long-term agreements (LTAs) that lock in volume and pricing. A prime example is isothermal forging deliveries to Pratt & Whitney, where ATI's content grew six times from 2023 to 2025. These LTAs not only secure revenue but also provide capital for expansion, as seen in the new VIM furnace project which is 80% contracted.
Significant capital investments are being made to unlock capacity in high-margin nickel alloys, specifically targeting a $350 million run rate of incremental revenue by mid-2028. The company is investing $220-$240 million (net of customer funding) in 2026, including a new primary melt VIM furnace. Crucially, these investments are underpinned by customer co-funding and long-term commitments, ensuring returns exceed the 30% threshold and mitigating the risk of overcapacity.
Specialty Energy is emerging as a meaningful third growth pillar, delivering 9% year-over-year growth in Q4. This growth is underpinned by multiyear commitments and accelerating demand for AI-driven power in nuclear and gas turbine markets. ATI recently renewed a major contract that expanded its share by over 20%, establishing it as the majority supplier. This segment leverages ATI's unique capabilities in zirconium and hafnium, providing diversification beyond the core A&D markets.
Airframe demand guidance was tempered to 'mid to upper single-digit' growth, weighted towards the second half of 2026. Management acknowledged that while Boeing's recent progress is encouraging, they are taking a 'conservative view' on the timing of the ramp and are not assuming immediate full-rate execution. This suggests potential near-term headwinds or inventory normalization that could delay revenue recognition in the first half of the year.
The guidance for Q1 2026 reflects seasonality and 'planned maintenance' in the High Performance Materials & Components (HPMC) segment, which will impact margins. Management noted Q1 consolidated EBITDA margins will be between 18.5% and 19%, dipping slightly from the Q4 2025 print of 19.7% before recovering later in the year. Investors should be wary of this sequential dip and the operational risks associated with ramping maintenance-heavy facilities.
While defense is growing, the company is strategically reducing capacity allocations in lower-margin industrial, medical, and electronics markets, with sales expected to trend down by low to mid-single digits. While this aligns with the strategy to focus on differentiated products, it creates a revenue headwind that the higher-growth segments must overcome. Additionally, the reliance on a few massive OEM programs (like Pratt & Whitney's GTF) creates concentration risk if specific engine programs encounter delays.
Overall: Management exhibited a highly confident and enthusiastic demeanor throughout the call, emphasizing momentum and execution capability. CEO Kimberly Fields was particularly assertive regarding the company's market position and proprietary advantages, while new CFO Rob Foster displayed precision and assurance in his financial guidance. The tone remained consistently positive from prepared remarks through the Q&A, with management deflecting concerns about airframe softness by highlighting strong demand in other segments.
Confidence: HIGH - Management provided specific, data-backed guidance and used definitive language such as 'absolute faith,' 'confident,' and 'strong foundation.' They explicitly stated they are 'guiding to $1 billion of adjusted EBITDA' and detailed specific capacity expansion plans with customer funding, indicating high visibility into future performance.

$3.99 - $4.27
$430 million - $490 million

18.5% - 19%
Hedging & Uncertainty: Management used minimal hedging regarding the core financial outlook, utilizing strong verbs like 'exceeded,' 'accelerating,' and 'strengthening.' However, some temporal hedging appeared around the airframe market, with phrases like 'anticipating that we'll start to see some modest improvement' and 'not assuming best case rate acceleration.' There was also specific hedging on the exact capacity impact of the new VIM furnace, described as 'mix dependent' and 'difficult to make,' which serves to manage expectations on the speed of the ramp.
We're seeing a step change increase in order activity beyond what we would normally see in seasonal first quarter strength. - Kimberly Fields, CEO
Our transformation continues as we focus our mix on ATI's most valuable products and customers. - Don Newman, Senior Adviser
We're evolving into a model of sustainable and growth in specialty energy, targeting double-digit growth in 2026. - Rob Foster, CFO
I do have some bias to the top end of the EBITDA margin percent and I do feel really confident with those 2027s. - Rob Foster, CFO
We are purposely prioritizing A&D and specialty energy using 80/20 and allocating differentiated production capacity to focus on our highest value markets. - Rob Foster, CFO
Analyst Sentiment: Analysts were generally inquisitive and focused on the sustainability of margins and the mechanics of the capacity expansion. Questions ranged from specific technical details about melt times to broader market share gains in defense. There was a clear interest in how the new CFO would approach capital allocation and guidance.
Management Responses: Management was responsive and detailed, with CEO Kimberly Fields handling the bulk of the operational and market-related questions while CFO Rob Foster tackled financial specifics. They effectively defended the conservative airframe guidance and elaborated on the 'step change' in orders, reinforcing the narrative of a multi-year growth cycle.

ATI is successfully executing a high-value strategic transformation, pivoting from a commodity industrial player to a differentiated leader in Aerospace, Defense, and Specialty Energy. The Q4 and FY 2025 results validate this strategy, showing robust margin expansion (up 900 bps since 2019) and significant free cash flow generation. The 2026 guidance for $1B+ EBITDA implies continued momentum, supported by secured LTAs and proprietary content in next-gen jet engines. The disciplined capital deployment strategy, bolstered by customer funding, de-risks the growth story. While airframe timing provides a modest near-term hurdle, the overwhelming strength in jet engines, defense, and specialty energy positions ATI for sustained profitable growth.
Management noted accelerating demand across both narrow-body and wide-body platforms, with next-generation engines gaining share. A 'step change' in order activity was observed in early 2026, suggesting supply chains are preparing for rate increases.
ATI is experiencing broad-based growth in defense, with increases across naval, air, missile, and ground systems. Missile revenue specifically surged 127%, driven by the need to replenish stockpiles for systems like PAC-3 and THAAD.
Demand for AI-driven power is accelerating, specifically in nuclear and land-based gas turbines. This is driving a multi-year growth cycle for ATI's specialty energy business, supported by long-term contracts.
