ATI Inc. Common Stock (ATI) fair value

ACCE thesis

ATI makes specialty materials, mainly titanium and nickel-based alloys, plus precision-rolled flat products, for aerospace, defense, and energy customers that need metal with tight certification requirements. The moat is qualification: aerospace and defense buyers approve a supplier and its alloy chemistry once, then rarely switch, which lets ATI earn above-commodity margins on what is still a mill business. Revenue is growing 10.6% and the operating margin sits at 18.2%, with ROE of 25.4%, so the business is converting that growth into returns. The forward P/E of 28.8 against a trailing 55.5 says earnings are expected to recover sharply, so the question for a deeper look is whether the aerospace and defense order book supports that step-up. The stock carries a 66/100 score and no index membership, so it sits outside the common screens that many holders use, which is worth knowing when weighing liquidity and the pace of any re-rating.
