Berkshire's operating profit dipped 4% year over year to $11.16 billion in the second quarter.

Berkshire Hathaway reported a 3.79% decline in second-quarter earnings as CEO Warren Buffett's company warned about President Donald Trump's tariffs on imported goods.

Buffett's conglomerate signaled it remains cautious about market valuations, amid uncertainty about tariffs and growth in the broader economy.

A move that caught many by surprise was a big write-down for Berkshire's underperforming Kraft Heinz stake.
