Shares rocketed 16.4% to $214.29 after ATI's management, speaking at a Morgan Stanley investor conference, painted a picture of a company entering 2027 at a $1.35 billion annualized EBITDA (earnings before interest, taxes, depreciation, and amortization — a common measure of operating profit) run rate. The commentary crystallized what two consecutive guidance raises this year had been hinting: ATI is no longer a cyclical metals business — it's becoming an aerospace margin machine.

  • A 57% Profit Jump Is Hard to Ignore

Aerospace and defense now account for 70% of ATI's revenue, up from about 50% in 2019, and second-quarter EBITDA rose 57% year over year while company-wide margins hit 23%.

The company exited its lower-margin standard stainless steel sheet business — roughly $400 million in revenue — and redirected resources to more specialized products. That deliberate trade of volume for profitability is what makes the margin expansion structural rather than just a good quarter.

  • The Path From $1.16 Billion Today to $1.35 Billion Next Year

Full-year 2026 guidance now sits at a $1.16 billion EBITDA midpoint, with EPS of roughly $5.04 and free cash flow of $575 million, backed by a record $4.4 billion backlog.

Management says Q4 2026 should be the strongest quarter, with a $1.35 billion annualized EBITDA exit rate that "directionally makes sense" for 2027. The bridge relies on new nickel melting capacity coming online, contract price resets, and consolidated incremental margins — meaning the profit earned on each additional dollar of revenue — now expected at roughly 50%, up from 40% earlier in the year.

  • Defense Spending Is Providing a Second Engine

Defense sales jumped 36% to a record $162 million in Q2, prompting ATI to raise its full-year defense growth outlook to the high teens.

ATI's content on next-generation jet engines is more than double that of legacy platforms , positioning the company to capture an outsized share as fleets modernize.

  • Risks Lurk Behind the Rally

ATI's deepening concentration in aerospace increases sensitivity to aircraft build rates, defense budgets, and program timing, while reliance on a limited set of major OEM customers heightens exposure to schedule shifts.

Analysts have also questioned whether mid-20% segment margins can hold into 2027. At $214, the stock trades at roughly 42 times trailing earnings — a price that assumes near-flawless execution on capacity ramps and contract conversions through next year.
