Meanwhile, there is positive news from the oil market: recovering crude oil exports from the Gulf region and a surprising increase in US inventories have somewhat eased supply fears on the oil market.

All of these key figures were well above market expectations. “We expect even better results for the 2026/2027 financial year,” said Sanjay Mehrotra, the head of the semiconductor manufacturer.
