German industrial giant Siemens on August 6, 2026 raised its outlook for the second time this year after a quarter boosted by spending on artificial intelligence but its shares still plunged. Along with other industrial firms such as France's Schneider Electric and Switzerland's ABB, Siemens -- which makes electrical gear -- has benefitted from demand for data centres that provide the computing power for AI.
