Hangzhou Silan Microelectronics (SHA:600460) forecasted first-half attributable net profit of about 519.1 million yuan, compared with 264.8 million yuan the previous year.
The 96% rise is attributed to strong revenue growth and a fair value gain of 194 million yuan from shareholdings in Anlogic, Yuneng and Lianxun Instrument, according to a Wednesday filing with the Shanghai bourse.
