China's Lenovo, the world's largest personal computer manufacturer, said fourth-quarter profit plunged 64% - a result that was far worse than expected and one that sent its shares sharply lower. The profit slide was mostly due to a fair value loss on warrants but the company was also hurt by the U.

While continuing to base production in China, Lenovo has built more than 30 self- or co-owned plants across 11 markets worldwide, Yang pointed out. This "global resources, local delivery" model ensures compliance with regional regulations and mitigates the impact of high tariffs, he said.
