Pandora has had several chief execs over the years. Westergren took over from Brian McAndrews in spring of 2016. That switch seemed to focus on whether or not the company’s leadership would be open to a sale. During Westergren’s latest tenure, Pandora was engaged in a long back-and-forth with Sirius XM about whether the satellite radio company might acquire it. Sirius XM just announced that it would invest $480 million in Pandora for a 19% stake and three seats on its board. It’s unclear at this point whether Westergren’s exit is related to the negotiations with Sirius XM.
Pandora has not issued a statement yet about the change in leadership.
