China's Lenovo Group reported a 43% jump in quarterly revenue on Thursday, beating forecasts to drive shares up as much as 22%, as the world's largest computer maker rides an AI hardware boom and benefits from a global memory chip shortage. Lenovo's revenue rose to $26.94 billion in the three months ended June 30, beating analyst expectations of $22.3 billion, as the consumer electronics hardware giant benefited from artificial intelligence-driven demand and solid PC sales.
