Pearson joined the retail chain in 2006 as marketing VP; was promoted to marketing senior VP in 2011; and was given added responsibility for e-commerce and strategy in January.
He was also tasked last year with developing strategic and transformation opportunities for the company’s marketing, store operations, merchandising and e-commerce functions.
The chain said in a federal filing that Pearson resigned to pursue another opportunity, after which his position was eliminated.
Functions reporting to Pearson have been assigned to other staffers, the company said.
Riesbeck is working to reverse hhgregg’s dour fortunes — which include a $9 million fourth-quarter loss — while vying for permanent assignment to the corner office.
Pearson served as a purchase experience senior manager at Whirlpool prior to joining hhgregg.
