Berkshire Hathaway Inc. shares rose as much as 5.5% in premarket trading on Monday, set to push the market value of Warren Buffett’s conglomerate even closer to $1 trillion.

The Omaha, Nebraska-based firm posted higher operating earnings, boosting a stock that’s been been crawling toward the trillion-dollar club since it notched a fresh record high last year. Surpassing that level would make Berkshire the first US company outside of the technology sector to reach such a market capitalization.

The company’s shares, which gained about 15% last year, were already up about 17% so far in 2024 through Friday. Its market value stood at more than $900 billion at the end of last week, before its Saturday earnings report.

“Extreme fiscal conservatism is a corporate pledge we make to those who have joined us in ownership of Berkshire,” Buffett wrote in his annual letter to shareholders. “Berkshire is built to last.”

Shares pared the premarket advance to 2.1% as of 8:17 a.m. New York time.

The conglomerate reported fourth-quarter operating earnings of $8.48 billion on Saturday, versus $6.63 billion for the same period a year earlier, helped by an increase in insurance underwriting earnings and investment income amid higher interest rates and milder weather.

“Berkshire Hathaway’s earnings power should remain intact given its diverse units that can offset pockets of weakness — regardless of economic conditions,” Bloomberg Intelligence analyst Matthew Palazola wrote in a note.

Omaha-based Berkshire’s businesses range from insurance to railroads and ice cream, a stark contrast to the tech giants that currently levy such valuations. Its stock trades in two classes — the more heavily traded Class B that now goes for more than $400 per share, and its longer-standing Class A that changes hands above $600,000.

Only a few US-based companies have ever attained market capitalizations above a trillion dollars.

Apple Inc. became the first in 2018, while Microsoft Corp. recently eclipsed the $3 trillion mark. Nvidia Corp. is flirting with a $2 trillion value. Inc., Alphabet Inc. and Meta Platforms Inc. are also currently valued above $1 trillion, while Tesla Inc. once crossed the mark but has since slumped.

Berkshire is the closest company outside of the tech giants, but that won’t necessarily mean it’s the first. Obesity drugmaker Eli Lilly & Co. has prompted analyst questions of whether it could be the first $1 trillion biopharmaceutical stock, as its market-capitalization rapidly topped $700 billion.

Meanwhile, Berkshire’s sheer size leaves meaningful deal-making more challenging, as there “remain only a handful of companies in this country capable of truly moving the needle at Berkshire,” according to Buffett’s letter. Its cash hoard has jumped to a record at $167.6 billion as the conglomerate struggled to find transactions at attractive valuations.

“All in all, we have no possibility of eye-popping performance,” Buffett wrote.
