Warren Buffett's investment conglomerate, Berkshire Hathaway, which he founded and long steered, may soon sell the vast majority or even the entirety of its stake in The Kraft Heinz Company (KHC.US). This move could come just months after the cheese and ketchup manufacturing giant announced plans to split into two separate entities. Statistical data reveals that Berkshire's investment in Kraft Heinz has resulted in a total loss of approximately $8.4 billion, including a $3.8 billion impairment charge recorded last year.

Following the official retirement of the legendary financier Warren Buffett on January 1, 2026, Berkshire Hathaway, the business empire he built over a lifetime, will enter a new era under the leadership of his designated successor, Greg Abel. For many years, Warren Buffett has been widely regarded as the world's greatest investor, having transformed Berkshire from a struggling New England textile mill—which he began acquiring shares of in 1962 at $7.60 per share—into the colossal conglomerate it is today, with its stock now trading at over $720,000 per share. Even after donating more than $60 billion over the past two decades, Buffett's personal wealth in Berkshire stock remains valued at around $150 billion.

In a filing on Wednesday, Kraft Heinz indicated that it had included the over 325 million common shares held by one of its largest investors, Berkshire Hathaway, in a potential sale arrangement. Following the news, Kraft Heinz's stock price fell sharply by up to 5.7% in pre-market trading.

Warren Buffett, the legendary investor who long helmed Berkshire Hathaway, publicly expressed disappointment last year regarding the company's planned split, although he had previously acknowledged that the 2015 merger did not proceed as originally envisioned. Public records show that Berkshire Hathaway holds about a 28% stake in the multinational food company and recorded an impairment loss of roughly $3.8 billion on this investment last year, bringing the cumulative loss on the investment to a staggering $8.4 billion.

Kraft Heinz is currently undergoing a significant transformation, announcing its split into two companies nearly a decade after its massive $46 billion merger. The company appointed a new Chief Executive Officer last month. Its chairman had previously attributed poor performance to an overly complex corporate structure and an inability to focus on capital allocation and the right strategic priorities.

Kraft Heinz initiated a process last year to unwind the super-merger. One of the resulting companies will sell its famous Heinz ketchup, condiments, and other packaged food products, generating annual sales of about $15.4 billion. The other company will sell its Oscar Mayer hot dogs and Lunchables product lines, currently producing revenue of approximately $10.4 billion. The separation is expected to be completed in the second half of this year.

The company appointed Steve Cahillane as its new CEO last month. Cahillane previously led the major split of Kellogg in 2023, which involved spinning off half of that business as Kellanova, later sold to Mars, Incorporated.

There is no indication yet that Berkshire has begun selling, but Cathy Seifert, a senior analyst at CFRA Research, suspects this might just be the beginning of a comprehensive review and cleanup of Berkshire's sprawling holdings. Beyond its massive equity portfolio valued at over $300 billion, Berkshire also owns various insurance companies including Geico, several utility companies, BNSF Railway, and a diverse array of manufacturing and retail businesses.

"My sense is that Abel's leadership style may differ from Buffett's, and if this sale goes through, it would represent a shift in the company's mindset," Seifert stated. "Under Buffett, Berkshire typically only acquired; it didn't divest. In our view, it's not unimaginable that Abel will evaluate each of Berkshire's subsidiaries and decide to jettison those that don't meet his internal benchmarks."

Of course, Abel is already intimately familiar with many of Berkshire's subsidiaries and business units, having managed all non-insurance operations since 2018. However, he only officially assumed the CEO role on January 1st of this year. Buffett remains Chairman, but investors are closely watching for any changes Abel might implement at the venerable conglomerate.

Abel has proven himself to be a more hands-on and involved top manager than Buffett, yet he still adheres to Berkshire's model of granting autonomy to acquired companies. Abel poses challenging questions to company leadership and holds them accountable for performance.

Indeed, Abel announced several leadership changes earlier last month: investment manager and Geico CEO Todd Combs departed, and Chief Financial Officer Marc Hamburg announced his retirement. Abel also stated he would appoint NetJets CEO Adam Johnson to oversee all of Berkshire's consumer, service, and retail businesses. This effectively creates a third major operating segment for the company and shares part of Abel's workload. He will continue to manage the large manufacturing operations, utilities, and the railroad.

Abel may soon face significant pressure from Berkshire shareholders, particularly regarding the potential initiation of dividend payments. From the beginning, Berkshire has maintained that reinvesting profits is superior to distributing them to shareholders quarterly or annually. However, if Abel cannot find productive uses for Berkshire's record $382 billion cash hoard, investors might push the company to begin substantial dividend payments or adopt a traditional stock buyback program to enhance the value of their shares. Currently, Berkshire only repurchases stock when Buffett deems it cheap, which he has not done since early 2024.

James Shanahan, a senior analyst at the Wall Street firm Edward Jones, noted that Warren Buffett's Berkshire Hathaway reported better-than-expected third-quarter results, primarily benefiting from significant improvement in its insurance underwriting business and solid contributions from its aerospace parts manufacturer, Precision Castparts. The analyst also believes that Abel, set to succeed Buffett at year-end, will rebuild investor confidence, supported by Berkshire's record cash reserve approaching $400 billion.
