Greenbrier fell to a 52-week low of $38.21 this week, down 35% from its high, with shares also slipping 3.27% to $38.78 on 7 October after UTLX Manufacturing, a Berkshire Hathaway subsidiary, initiated a trade dispute seeking antidumping and countervailing duties on railway tank car production. Greenbrier has formally rejected the petitions, calling the allegations factually unsupported and committing to defend its U.S. production record. Separately, the company scheduled its fourth quarter fiscal 2026 earnings release and conference call.
