Taiwan Semiconductor Manufacturing Company (TSMC) has reported consolidated revenues of NT$81.87 billion (US$2.74 billion) for April 2018, down 21% sequentially but up 44% on year.

TSMC expects to post a 7-8% sequential decrease in consolidated revenues for the second quarter of 2018. "Continued weak demand from our mobile sector will negatively impact our business despite strength in cryptocurrency mining," said TSMC CFO Lora Ho when giving the foundry's sales guidance for the second quarter.

TSMC has cut its revenue growth forecast for 2018 to 10% from the previously-estimated 10-15%, citing weaker-than-expected smartphone demand and growing uncertainty facing the cryptocurrency mining market. The world's largest contract chipmaker also revised its growth forecasts for global foundry and overall IC market outlook this year to 8% and 5%, respectively, compared to 9-10% and 5-7% estimated previously.

TSMC disclosed revenues for January through April 2018 totaled NT$329.95 billion, an increase of 13.5% compared to the same period in 2017.
