NEW YORK (AP) — Kraft Heinz is splitting into two companies a decade after they joined in a massive merger that created one of the world’s biggest food companies on the planet.

One of the companies will include shelf stable meals and include brands such as Heinz, Philadelphia cream cheese and Kraft Mac & Cheese, Kraft Heinz said Tuesday. The other will include brands such as Oscar Mayer, Kraft Singles and Lunchables. The names of the two companies will be released later.

Kraft Heinz said in May that it was conducting a strategic review of the company, signaling a potential split.

“Kraft Heinz’s brands are iconic and beloved, but the complexity of our current structure makes it challenging to allocate capital effectively, prioritize initiatives and drive scale in our most promising areas,” Executive Chair Miguel Patricio said in a statement.

The path to the merger of Kraft and Heinz began in 2013, when billionaire investor Warren Buffett teamed up with Brazilian investment firm 3G Capital to buy H.J. Heinz Co. At the time, the $23 billion deal was the most expensive ever in the food industry.

3G was also behind the formation of Restaurant Brands International — a merger of Burger King, Tim Hortons and Popeyes — and Anheuser-Busch InBev. It’s known for strict cost controls and so-called zero-based budgeting, which requires all expenses to be justified each quarter.

The deal was intended to help Heinz, which was founded in 1869 in Pittsburgh, expand sales of its condiments and sauces on grocery store shelves. Heinz’s new owners also set about cutting costs, laying off hundreds of workers within months.

At the same time Kraft, based in Chicago, sought for a partner after a 2011 split from its snack division, which became Mondelez International.

In 2015, Buffett and 3G decided to merge Heinz with Kraft. The merger created the 5th largest food and beverage company in the world, with annual revenue of $28 billion. Buffett and 3G each contributed $5 billion for a special dividend for Kraft shareholders.

But the combined company struggled, despite layoffs of thousands of employees and other cost-cutting measures. Even at the time of the merger, many consumers were shifting away from the kinds of highly processed packaged foods that Kraft sells, like Velveeta cheese and Kool-Aid.

Kraft Heinz also had trouble distinguishing its products from cheaper store brands. At Walmart, a 14-ounce bottle of Heinz ketchup costs $2.98; the same size bottle of Walmart’s Great Value brand is 98 cents.

In 2019, Kraft Heinz slashed the value of its Oscar Meyer and Kraft brands by $15.4 billion, citing operational costs and supply chain problems. But many investors blamed the company’s leadership, saying its zeal for cost-cutting was hurting brand innovation.

In 2021, Kraft Heinz sold both its Planters nut business and its natural cheese business, vowing to reinvest the money into higher-growth brands like P3 protein snacks and Lunchables.

But the company’s net revenue has fallen every year since 2020, when it saw a pandemic-related bump in sales. In April, Kraft Heinz lowered its full-year sales and earnings guidance, citing weaker customer spending in the U.S. and the impact of President Donald Trump’s tariffs.

Kraft Heinz has no plans to change its current headquarter locations in Chicago and Pittsburgh. It currently expects the transaction to close in the second half of 2026.

Shares of the company rose slightly before the market open.
