OHB is trading 8.8% down at €198.80 on November 5, 2026, with the cause still uncertain.
- The sharp reversal follows a November 4 close of €218.00 and an earlier report of a €554 million ESA satellite contract win, which does not explain the decline.
- No OHB-specific negative announcement surfaced. European shares were broadly higher, while technology stocks lagged amid concerns over AI infrastructure scrutiny; broad-market weakness is not a clear explanation.
