Chip price increases spread as STMicroelectronics, ADI and Maxscend raise supply quotes

The semiconductor sector is entering another round of price increases driven by both supply-demand pressure and rising costs, with analog and RF chips at the center of the latest moves. Chinese media outlets including 21 Finance reported that multiple chip companies in China and overseas sent price adjustment notices to customers after the start of August. Documents circulating in the market show that STMicroelectronics, Analog Devices and Maxscend have all set new supply prices for the second half of the year. STMicroelectronics, a major supplier of power semiconductors and MCUs, plans to implement another price increase on Aug. 23 across several product lines. The company has already raised prices twice earlier in 2026. Analog Devices is set to roll out a broad portfolio-wide adjustment on Sept. 13, its second increase this year after a previous round took effect on Feb. 1. In China, RF front-end supplier Maxscend said its full RF product lineup will see higher supply prices starting Sept. 1, while Nationstech told Jiemian News it will raise prices on some high-performance MCUs by 10% to 20% from Oct. 1. The report said the latest round differs from the first half of the year, when HBM and server DRAM led the market. This time, pricing pressure has shifted toward mature-node chips, with AI demand, tighter foundry and packaging capacity, and higher raw material costs all feeding into the move.
