ATI Inc. (ATI) Earnings: Q3 Fiscal 2026 Results

The quarter ended September 27, 2026 and ATI published the results on October 29, 2026. Revenue and diluted EPS are shown against Q3 fiscal 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. ATI reports EPS two ways: GAAP, under the accounting rules every US filer follows, and adjusted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

How ATI splits revenue in its own release, under its own labels, for Q3 fiscal 2026 against Q3 fiscal 2025. Indented lines are parts of the line above them.

• ATI's High Performance Materials & Components revenue was $721 million in Q3 fiscal 2026, up 20% from $603 million in Q3 fiscal 2025, 51% of total revenue.
• ATI's Advanced Alloys & Solutions revenue was $702 million in Q3 fiscal 2026, up 34% from $523 million in Q3 fiscal 2025, 49% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

“Raising full-year 2026 guide by $35 million to $1.195 billion; follows raise of $125 million last quarter”

“We are raising our full-year outlook for adjusted EBITDA by $35 million. This follows the $125 million increase in our outlook just last quarter”

We do not hold a confirmed date for ATI's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 fiscal 2026 (this page), reported Oct 29, 2026

ATI makes specialty materials and parts, and aerospace and defense is most of its business: $994.5 million of the $1,423.7 million in Q3 2026 sales, or 69%. Commercial jet engines alone were $603.2 million, 42% of sales, up from $433.6 million a year earlier. Commercial airframes brought in $219.4 million and defense $171.9 million. (ATI Q3 2026 earnings release, Oct 29, 2026)

ATI reports two segments of almost equal size. High Performance Materials & Components (HPMC) had sales of $721.4 million, up 20%, which ATI attributed mainly to a 34% increase in sales of commercial jet engine products on strong demand and pricing; aerospace and defense was 94% of HPMC sales. Advanced Alloys & Solutions (AA&S) had sales of $702.3 million, up 34%, as its sales of commercial jet engine products almost doubled. (ATI Q3 2026 earnings release, Oct 29, 2026)

By product, nickel-based alloys and specialty alloys were 52% of ATI's sales in the quarter, against 44% a year earlier. Precision forgings, castings and components fell to 17% from 22%, titanium and titanium-based alloys to 16% from 19%, and zirconium and related alloys were 10%. (ATI Q3 2026 earnings release, Oct 29, 2026)

Outside aerospace, ATI's specialty energy sales rose to $80.4 million from $53.9 million and conventional energy to $82.3 million from $56.8 million, while electronics fell to $46.5 million and medical to $25.6 million. ATI's 10-K says no single customer accounted for more than 10% of sales, and international sales were approximately 42% of total annual sales. (ATI Q3 2026 earnings release, Oct 29, 2026; ATI Form 10-K, fiscal 2025, Feb 20, 2026)

ATI's backlog of confirmed orders was $4.3 billion at September 27, 2026, against $3.6 billion a year earlier, and approximately 75% of it is expected to be satisfied within the next 12 months. The 10-K describes long-term agreements with aerospace OEMs, including a titanium supply agreement with Boeing for airframe products. (ATI Form 10-Q, Q3 fiscal 2026, Oct 29, 2026; ATI Form 10-K, fiscal 2025, Feb 20, 2026)

ATI's GAAP diluted EPS was $1.37, up from $0.78, and adjusted EPS was $1.46, up from $0.85. Adjusted results exclude $15.6 million of pre-tax special items: $14.4 million of restructuring and other charges, made up of $8.4 million of transformation-related costs, $2.9 million of losses on the sale of customer accounts receivable, $2.2 million of start-up and transaction-related costs and $0.9 million of restructuring costs, plus a $1.2 million debt extinguishment charge. After tax they cost $0.09 a share. (ATI Q3 2026 earnings release, Oct 29, 2026)

ATI's diluted share count fell to 138.4 million from 140.5 million. In the quarter ATI repurchased $70.0 million of stock at an average price of $199.62, retiring approximately 0.4 million shares, and had $425 million of repurchase authorization left. The effective tax rate was 21.0%, against 21.4% a year earlier. (ATI Q3 2026 earnings release, Oct 29, 2026)

ATI's AA&S segment EBITDA rose to $181.3 million, 25.8% of sales, from $90.4 million, which ATI attributed to higher pricing and volumes and a favorable mix. HPMC segment EBITDA was $167.3 million, 23.2% of sales, down from 24.2%, because of higher manufacturing and period costs including the ramp of commercial production of a new nickel-based superalloy. (ATI Q3 2026 earnings release, Oct 29, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

ATI gives quarterly and full-year guidance in its release, in adjusted terms. For Q4 2026 it guides adjusted EBITDA of $345M to $355M and adjusted EPS of $1.51 to $1.57. For full year 2026 it raised adjusted EBITDA guidance to $1,190M to $1,200M, from $1,135M to $1,185M, and adjusted EPS to $5.17 to $5.23, from $4.90 to $5.18, and kept adjusted free cash flow at $550M to $600M. (ATI Q3 2026 earnings release, Oct 29, 2026)

ATI said reconciliations of these forward-looking non-GAAP figures to GAAP are not available without unreasonable effort, so the release gives no GAAP EPS outlook. (ATI Q3 2026 earnings release, Oct 29, 2026)

A consensus figure is the average of the models published by the analysts who cover ATI, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones ATI's own release and filings put weight on for Q3 fiscal 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning ATI is on is ATI a buy or a sell?, what analysts expect next is on the ATI forecast, and what the company does is on the ATI Inc. (ATI) stock page.

Every number on this page can be traced to a document ATI published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
