A decade after their merger created a global food giant, Kraft Heinz said early Tuesday that it planned to split into two separate companies.

It plans to spin off its slower-growing grocery business, which includes well-known brands like Oscar Mayer, Kraft Singles and Lunchables, into a new entity. The remaining company would house sauces, condiments and products with faster-growing sales, like Heinz ketchup, Philadelphia cream cheese and Kraft Mac & Cheese.

Most large food companies are struggling as consumers purchase less of what they sell. In some cases, the slowdown is from consumers who, after two years of food inflation, are making tougher choices about where they spend their dollars in the grocery store. But many consumers also are veering away from so-called highly processed foods.

That shift has put pressure on food companies’ stock, and executives at Kraft Heinz are betting that the company will be worth more to investors split into two separate entities. They said Tuesday morning that in splitting the companies, they can give each business dedicated attention and resources.

“This move will unleash the power of our brands and unlock the potential of our business,” Carlos Abrams-Rivera, the chief executive of Kraft Heinz, said in a statement.

Still, that is a reversal of the argument made a decade ago, when Kraft and Heinz combined in a merger that created one of the largest food companies in the world, with more than $28 billion in annual revenues and a plethora of household staples, from Kool-Aid to Velveeta.
