Shares in the German software giant SAP suffered their biggest one-day drop in five years on January 29, 2026 after disappointing earnings, extending a months-long slide driven by fears that AI could disrupt its business. Shares in Germany's most valuable listed company fell as much as 16 percent on the Frankfurt Stock Exchange to around 164 euros ($196), the steepest one-day decline since October 2020.
