CDK Global’s former top executive is back as acting president and chief executive officer, replacing the leader who replaced him.

Brian MacDonald, who was the president and CEO of CDK Global from January 2016 to November 2018, takes over for Brian Krzanich, who the company announced is stepping down.

Back in November 2018, it was MacDonald who stepped down from the position, with Krzanich becoming president and CEO.

“We are pleased to welcome Brian MacDonald, a respected executive with deep expertise in automotive retail, back to CDK,” said Doug Bayerd, director on CDK’s board, in a news release. “He joins an experienced team to help enhance CDK’s value proposition for its customers.”

MacDonald added: “CDK is a mission-critical software platform for automotive commerce with a bright future, and I am excited about our path forward and accelerated growth.”
