"The coronavirus outbreak in China is hitting hard many in the supply, but TSMC is a major exception. The world's top pure-play foundry has no plans to revise its sales guidance for the first-quarter, and reportedly none of its major clients are cutting orders despite the epidemic, with the foundry's capacity supply remaining tight. While even TSMC's China fabs have been able to maintain smooth operation, others in the IT sector have difficulties returning to normal production though work at their China plants has resumed. Foxconn and Pegatron, like many other Taiwan-based makers running manufacturing plants in China, are seeing limited numbers of employees returning to work. Failure to resume full production at Foxconn and Pegatron will affect iPhone shipments to Apple.
TSMC continues to see its supply remain tight, with no cutbacks in orders from its major fabless clients such as Huawei's HiSilicon, according to sources familiar with the matter."
