Samsung Electronics on Tuesday projected a far worse than expected 56% plunge in second-quarter operating profit due to weak AI chip sales, deepening investor concerns over the tech giant's ability to revive its struggling semiconductor business.

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.

Samsung forecasts a 55.9 per cent fall in Q2 profit due to weak chip demand, US trade curbs, and inventory costs. Q3 recovery expected with higher HBM demand and improved foundry utilisation.
