ATI Inc.

ATI makes specialty metals — titanium ingots and mill products, nickel superalloys, precision forgings — for aerospace, defense, medical devices, and industrial customers. The stock is up 200% over the last year because the multi-year pivot to aerospace and defense finally locked in during a demand cycle where Boeing/Airbus deliveries are accelerating and the defense-titanium supply chain is scrambling for capacity.

• Growth is quietly compounding above expectations: revenue growth of 0.6-7% quarterly looks modest, but Q2 EPS beat 19% and Q1 beat 14% — the operating leverage of the aerospace mix shift, since every extra pound of titanium into a jet engine flows through at much higher margins than industrial alloy work.
• The Q2 print was the guide-raise moment: management raised FY26 guidance on the Q2 beat and the stock hit fresh all-time highs — that's when analysts pull FY27 estimates higher, which supports the compounder tape.
• The valuation is fully priced for the cycle: 57x trailing earnings and 30x EV-to-EBITDA is a growth-stock multiple on a specialty-metals business — the FY27 consensus of $5.42 puts the forward multiple near 40x, which needs the aerospace ramp to keep beating expectations.

Trajectory is accelerating at 90% of the 52-week range with the tape running with the metals-materials cohort (RS, NEU); the Oct 27 Q3 print needs another beat plus reaffirmed FY26 raise to justify the multiple — a Boeing production hiccup or a soft defense-titanium quarter puts the multiple back toward peer levels fast.
