Samsung Electronics on Tuesday projected a 56% drop in second-quarter operating profit from a year earlier, far worse than analysts expected as its struggling chip business faced U.S. chip curbs on China.

Samsung Electronics reported a 4.6 trillion won ($3.34 billion) operating profit for the second quarter of this year, down 55.94 percent from the same period last year.

Samsung Electronics is expected to forecast a 39% plunge in second-quarter operating profit on Tuesday, weighed down by delays in supplying advanced memory chips to artificial intelligence chip leader Nvidia.
