Ex-China heavy rare-earth metallization/alloying

AI supply-chain thesis — mapping bottlenecks, focus companies, and supply-chain exposure for investors.

**Bottleneck theme:** Rare Earths **Focus:** $ALOY — REALLOYS INC. Ex-China heavy rare-earth metallization and alloying is one of the most underappreciated chokepoints in the Western defense and AI supply chain. China controls 90%+ of heavy rare-earth (Dy, Tb, Sm) separation and alloying capacity, and recent export controls on rare-earth metals and magnets have made it a national-security imperative for the U.S. to stand up domestic alternatives. ReAlloys (formerly USA Rare Earth's metallization arm) is one of a small handful of Western players with the metallurgical know-how to take separated rare-earth oxides and turn them into the alloys and ingots used in NdFeB sintered magnets — the missing middle of the magnet supply chain. The Pentagon's interest is not theoretical: DPA Title III dollars, IBAS funding, and direct prime-contractor offtake agreements are flowing to qualified domestic alloyers. The investment case for $ALOY is binary execution — scale a process that has never run at industrial volumes outside China, in a politically protected market with subsidised capex and pre-committed offtake. Pair-trade companion to $MP (the upstream miner) and the magnet makers ($USAR, Quadrant, Less Common Metals); without metallization between mining and magnets, $MP's REO doesn't reach an F-35 magnet.
