According to online reports, NVDA.O's overall revenue in the first quarter increased by 69% year-on-year to US$44.1 billion, higher than market expectations of US$43.1 billion. Data center revenue increased by 73% year-on-year to US$39.1 billion (market expectations of US$39.3 billion), accounting for 88% of sales. Nvidia rose 5% after hours. The company's share price has been relatively flat so far this year, after nearly tripling last year. Nvidia said that overstocking of H20 chips in the first quarter generated $4.5 billion in expenses, and if it were not restricted, the company would have recorded additional $2.5 billion in sales. Nvidia CEO Huang Renxun had earlier predicted that the revenue impact related to H20 chip export restrictions would be approximately US$15 billion. Nvidia said in its earnings report that if it does not take into account sales losses caused by recent export restrictions on its H20 chips, its results are expected to be approximately $8 billion higher. Nvidia expects second-quarter revenue to be US$45 billion, up or down by 2%, and the market forecast is US$45.9 billion.
