The company that oversees the Domino’s Pizza brand in Russia said it will file for bankruptcy there, signaling a definitive end to its operations in that country nearly 18 months after President Vladimir Putin launched an unprovoked invasion of neighboring Ukraine.

DP Eurasia, the franchisee for Domino’s in Europe and Asia, cited unspecified business challenges in Russia, where it operated more than 100 restaurants. The U.S.-based Dominos Pizza has said it cut off financial support for the Russian business in December 2022.

A bankruptcy filing is now forthcoming, the company said.
