Warren Buffett's Berkshire Hathaway (NYSE:BRKa) slashed its stake in Apple (NASDAQ:AAPL), today's quarterly earnings report showed.

Berkshire's Apple investment is now valued at $135.4 billion, reflecting ownership of approximately 790 million shares. This adjustment signifies a 13% decrease in the company's stake in the tech giant.

Still, Apple remains the largest holding in Berkshire's portfolio.

“It doesn’t bother me in the least to write that check — and I would really hope with all that America’s done for all of you, it shouldn’t bother you that we do it —and if I’m doing it at 21% this year and we’re doing it a little higher percentage later on, I don’t think you’ll actually mind the fact that we sold a little Apple this year,” Buffett said during Berkshire Hathaway’s annual meeting.

Apple stock surged last week after the tech giant announced a record $110 billion share buyback authorization despite falling iPhone sales. 

As of the end of the first quarter, Berkshire Hathaway remains the largest shareholder in Apple, excluding exchange-traded fund providers.

Earlier today, Warren Buffett-controlled company reported operating income of $11.22 billion, which represents a 32% rise from $8.48 billion in Q1 2023.
