SEOUL (Reuters) -Samsung Electronics ( SSNLF ) on Tuesday projected a 56% drop in second-quarter operating profit from a year earlier, missing analysts' estimates by far.

Its chip business struggled with weak sales of artificial intelligence chips, dogged by delays in the supply of its latest chips to Nvidia ( NVDA ) and continued losses in its contract chip manufacturing business, analysts said.

The world's largest memory chipmaker estimated an operating profit of 4.6 trillion won for the April-June period, versus a 6.2 trillion won LSEG SmartEstimate.

That would compare with 10.4 trillion won in the same period a year earlier and 6.7 trillion won in the preceding quarter.

Revenue would likely fall 0.1% to 74 trillion won from a year earlier, the filing showed.

Samsung is expected to release detailed results including a breakdown of earnings for each of its businesses in late July.
