Dow could gain share as the Strait of Hormuz closure cuts naphtha supply to Japanese photoresist makers, who hold over 90% share and rely on the Middle East for 40% of their naphtha. Dow has the largest PGME/PGMEA share at about 22%, full backward integration and spare Texas capacity; its CEO cites a positive margin inflection and surging orders. A quick reopening would reverse some uplift, but its cost edge is structural. Eastman, a purer play, is preferred; no parabolic run is expected. x.comÂ
