Defense Advanced Materials
All research in Defense Advanced Materials — 4 reports.
ATI is a high-barrier aerospace and specialty materials company whose operating quality has improved, with aerospace and defense now 68% of sales. But at the current price of $178.48 the stock trades at roughly 28.8x EV/EBITDA against an intrinsic value of only $60–145, leaving an insufficient margin of safety. Rating Watch: a strong business at the wrong price.
Carpenter Technology is a leading aerospace specialty-materials company whose operating quality has improved sharply, yet at the current price of $487.25 (51x PE) the stock is extraordinarily expensive, with fair intrinsic value of only $150–190 and no margin of safety. Rating Watch: a fine business at a poor price, with future growth and peak margins already paid for.
A beryllium and advanced-materials maker with a moderate moat, but at roughly $230 the stock sits far above a fair intrinsic value of $70–95, leaving no margin of safety. Resource scarcity, process know-how, and qualification-based switching costs are real, yet the current price already discounts years of flawless execution. Rating Watch: a good business at a bad price, with a fair buy range of $55–70.
From a Buffett lens, the verdict is Avoid. Sphere has reinvented itself as an aerospace specialty-alloy supply-chain operator (99.8% of revenue from aerospace alloys), but 2025 operating cash flow was -KRW 14.67 billion, and the KRW 1.65 trillion market cap already exceeds the KRW 1.544 trillion headline of the ten-year SpaceX contract. At the current KRW 32,500, the stock sits well above an optimistic intrinsic-value range of KRW 19,000–28,000, leaving no margin of safety. Rating Avoid: a good industry attached to a price that prices in too much.
