ATI Inc. - the specialty-metals company that lives inside jet engines, airframes, nuclear reactors and naval ships - delivered a Q2 FY2026 print that landed above the high end of its own guidance on every line management pre-committed to. Sales of $1.26 billion rose 11% year over year. Net income attributable to ATI of $151 million climbed 50%. GAAP diluted earnings per share of $1.09 rose 56%, the adjusted number of $1.23 climbed 66%, and adjusted EBITDA of $284.4 million at a 22.6% margin expanded 440 basis points. Backlog hit another record at $4.4 billion, up 18% year over year. The picture is the same one ATI has been painting for four quarters, but with sharper edges: 68% of sales now come from aerospace and defense, the AA&S segment just turned a margin corner, and management used the same release to raise full-year 2026 guidance for adjusted earnings, adjusted EBITDA, and free cash flow - every range, all three. The market had already priced much of the run; the stock closed 8/13 at $227.22, an all-time high that is 7% below the 52-week intraday peak of $243.57 and 222% above the 52-week low of $70.42. This is a company whose earnings engine is finally matching its order book, and the quarter is the print that proves it.
The headline read, though, would miss the second-look story. Two things happened in the quarter that are easy to under-weight and hard to over-weight. First, ATI refinanced its capital structure - issuing $450 million of new 5.875% senior notes due 2033 on 6/3/2026, using $350 million of the proceeds on 7/8/2026 to redeem the legacy 5.875% notes due 2027, with the rest to general liquidity. The next meaningful maturity is $325 million of 4.875% notes in Q4 FY2029, and the company entered the quarter with $783 million of cash and approximately $570 million of additional ABL revolver capacity. Second, the consolidated revenue mix is now anchored on aerospace and defense at 68% - up from 66% a year ago and 60%+ a few years back - and within that, commercial jet engine sales alone were $508 million in the quarter, 40% of total company sales and growing 14% year over year. The investment case is no longer "specialty metals with an aerospace tilt." It is "aerospace and defense, expressed in metals." The bears have lost the secular-demand argument; the question now is whether margin expansion can keep compounding against the cost ramp of a new Mexico facility, a new titanium electron-beam furnace, and the operating-leverage denominator of a stock that has more than tripled in 18 months.
