ATI Q3 2026 Earnings: AA&S Margin Expansion Drives 46% Adjusted EBITDA Growth

ATI Inc. (NYSE: ATI) reported fiscal Q3 2026 sales of $1.4237 billion, up 26% from $1.1255 billion a year earlier, while GAAP diluted EPS rose to $1.37 from $0.78. Adjusted EBITDA increased 46% to $327.9 million and its margin expanded to 23.0%, as gains in Advanced Alloys & Solutions more than offset margin pressure in High Performance Materials & Components. The quarter ended September 27, 2026, and ATI raised its full-year adjusted EBITDA guidance with the October 29 release.

Core Financial Results

Revenue growth translated into faster profit growth. Gross profit increased approximately 49% and operating income rose about 67%, both well above the 26% sales increase, reflecting pricing, higher volumes and a more favorable sales mix led by the AA&S segment.

Adjusted results excluded $15.6 million of pre-tax special items, including restructuring and other charges and a debt extinguishment charge. The after-tax effect was $12.1 million, or $0.09 per share.

Gross and operating margins are calculated from the reported sales and profit figures. Adjusted EBITDA, adjusted EPS and adjusted free cash flow are non-GAAP measures.

Business and Segment Performance

Both operating segments generated higher sales and EBITDA, but AA&S delivered substantially greater margin expansion and earnings growth.

High Performance Materials & Components, or HPMC, benefited from demand and pricing for commercial jet engine products, whose sales increased 34% year over year. Aerospace and defense accounted for 94% of segment sales. However, higher manufacturing and period costs—including expenses related to ramping commercial production of a new nickel-based superalloy—reduced the segment’s EBITDA margin from 24.2% to 23.2%.

Advanced Alloys & Solutions, or AA&S, recorded 34% sales growth as aerospace and defense, specialty energy and conventional energy revenue increased. Aerospace and defense sales rose 34%, with commercial jet engine sales nearly doubling. Higher pricing, volume and a favorable sales mix lifted segment EBITDA to $181.3 million from $90.4 million and expanded margin by 850 basis points.

Across ATI, aerospace and defense generated $994.5 million, or 69% of quarterly sales, compared with $792.7 million a year earlier. Commercial jet engines were the largest market category at $603.2 million, representing 42% of total sales.

AA&S Margin Expansion Offset HPMC Ramp Costs

AA&S generated approximately 81% of the $112.4 million year-over-year increase in combined segment EBITDA, before corporate and other items. Its $90.9 million EBITDA increase substantially exceeded HPMC’s $21.5 million gain, despite both segments reporting double-digit sales growth.

The combined segment increase translated into a $102.8 million rise in consolidated adjusted EBITDA because corporate, closed operations and other expense increased by $9.6 million to $20.7 million. ATI cited higher professional fees and insurance costs, while the prior-year period benefited from a $10.5 million gain on the sale of oil and gas rights. Even with those offsets, ATI’s adjusted EBITDA margin expanded by 300 basis points.

Cash Flow and Balance Sheet

Cash conversion did not keep pace with earnings. Quarterly operating cash flow declined to $154.6 million from $229.5 million, while adjusted free cash flow fell to $79.6 million from $199.7 million. Capital expenditures were $92.8 million during the quarter.

Managed working capital increased by $142.9 million sequentially to $1.8742 billion, although it declined as a percentage of annualized sales to 32.9% from 34.3%. The lower ratio reflects annualized sales growing faster than the working-capital balance; it does not represent a decline in working-capital dollars.

ATI ended the quarter with $442.3 million of cash and cash equivalents. Short- and long-term debt totaled $1.8575 billion, compared with $1.7494 billion at the end of fiscal 2025. The company also repurchased approximately 0.4 million shares for $70.0 million during Q3, leaving $425 million under its repurchase authorization.

Earnings Guidance

ATI raised the midpoint of its full-year adjusted EBITDA outlook by $35 million to $1.195 billion. The adjusted EPS range also moved higher, while adjusted free cash flow guidance remained unchanged despite lower year-over-year quarterly cash generation.

At the midpoint, full-year adjusted EPS guidance increased to $5.20 from $5.04. The Q4 adjusted EBITDA midpoint of $350 million is approximately 7% above the Q3 result.

Management’s View

Chair, President and CEO Kimberly A. Fields attributed the quarter’s performance to demand supported by long-term agreements, ATI’s differentiated production capabilities and operating execution. Management emphasized the balance of the company’s portfolio and said it was positioning the business for further performance gains in 2027.

Recent Insider Transactions

Reported insider activity over the latest six-month period included 9,146 shares purchased across 10 transactions and 294,529 shares sold across 12 transactions, resulting in net sales of 285,383 shares. The 10 latest reported transactions consisted of nine sales and one derivative-security exercise conversion, with total disclosed value of approximately $34.79 million.

All listed transactions were reported as direct holdings. The disclosures describe the transactions but do not establish the insiders’ views about ATI’s valuation or outlook.

Risks Investors Should Watch

• HPMC production-ramp costs: Demand and sales grew, but higher manufacturing and period costs associated with the new nickel-based superalloy reduced segment margin. Continued ramp costs could limit earnings leverage from revenue growth.
• Cash conversion: Adjusted free cash flow declined sharply year over year. With $222.8 million generated year to date and full-year guidance of $550 million to $600 million, ATI would need approximately $327.2 million to $377.2 million in Q4 adjusted free cash flow to reach the range.
• Aerospace and defense concentration: Aerospace and defense accounted for 69% of total sales and 94% of HPMC sales. Changes in commercial jet engine production, defense demand or customer schedules could have a material effect on results.
• Execution against higher guidance: ATI’s Q4 adjusted EBITDA target is above the Q3 result and assumes continued benefits from demand, pricing, volume and mix. HPMC cost pressure or weaker AA&S operating leverage could make the raised full-year range harder to achieve.

Summary

ATI’s Q3 2026 results combined 26% sales growth with substantially faster earnings growth, led by AA&S pricing, volume and mix. HPMC continued to grow but faced margin pressure from manufacturing and new-product ramp costs, while cash flow lagged the improvement in reported profit. The main issues to monitor are whether AA&S can sustain its margin gains, whether HPMC can control ramp costs and whether Q4 cash generation is sufficient to support the unchanged full-year free cash flow outlook.
