Just over a week after Indigo Books & Music announced that CEO Peter Ruis was stepping down from his role at the retailer, the company announced on September 18 that founder and longtime CEO Heather Reisman would be returning to the top post.

Reisman has also been reappointed to the board of directors, Indigo said in a press release, a position she previously held until her retirement this summer.

Reisman’s return to the C-suite is accompanied by several other changes: CFO Craig Loudon has been appointed chief operating officer; former Penguin Random House CEO Markus Dohle has been appointed chair of the board; and Eileen Naughton, formerly chief people officer at Google Inc., has been appointed to the board of directors.

Monday’s announcement is the latest shakeup at Indigo. In early June, alongside the announcement of Reisman’s retirement, the company also announced that four of its directors had stepped down from the board, with Dr. Chika Stacy Oriuwa making the decision “because of her loss of confidence in board leadership and because of mistreatment.”

The changes come as Indigo gears up to launch its new store concept with a flagship store at The Well in Toronto this month, and as the company seeks to regain momentum after sustaining a ransomware attack in February that has cost it millions.

In a press release, Indigo said the appointments are “part of a drive to strengthen its brand focus and propel the company toward growth and profitability.”
