Krispy Kreme and McDonald’s collaboration has come to an end.

The companies announced Tuesday that they’re ending their partnership, putting a final pin in the plan to sell Krispy Kreme’s doughnuts in McDonald’s locations.

In a press release about the decision, Krispy Kreme explained that while they were initially excited to collaborate with McDonald’s, the business model ultimately wasn’t profitable for the doughnut chain.

“Our two companies partnered very closely, each supporting execution, marketing, and training, delivering a great consumer experience in approximately 2,400 McDonald’s restaurants,” said Josh Charlesworth, the CEO of Krispy Kreme, in the press release. “Ultimately, efforts to bring our costs in line with unit demand were unsuccessful, making the partnership unsustainable for us.”

The companies first announced the plan in March 2024. Last month, Krispy Kreme delayed the rollout. In its earnings report, the doughnut chain said it was “reassessing the deployment schedule with McDonald’s while it works to “achieve a profitable business model for all parties.” The two companies later announced that they wouldn’t launch the sale of Krispy Kreme doughnuts in any remaining McDonald’s locations.
