Whole Foods shares rose as much as 5 percent to $29.91 in afternoon trading, coming off a halt after the report, before giving up most gains to trade up about 1 percent.
The company had a market capitalization of $9.07 billion as of Thursday's close and its top 10 shareholders include the Vanguard Group, BlackRock Institutional Trust Co and Neuberger Berman LLC, according to Thomson Reuters data.
"Whole Foods Market values the strong and open relationships we have with our shareholders," spokeswoman Brooke Buchanan said in an emailed response.
"We are focused on pursuing the right strategies to position the company to produce strong results and returns for our shareholders over the long term."
Whole Foods on Wednesday said co-founder John Mackey would resume his job as solo chief executive officer six years after he split the role with co-CEO Walter Robb, known as the businessman who carried out Mackey's vision.
The Austin, Texas-based grocer has reported five quarters of falling sales at established stores, and while the decline may be easing, Whole Foods faces intense competition.
