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.

According to the smart estimates, Samsung was expected to post an operating profit of 6.26 trillion won ($4.57 billion) for the quarter.

Samsung Electronics faces a pivotal moment in the AI chip market, battling weak profits, delayed HBM shipments, and U.S. export curbs while investing heavily to regain leadership.
