Longbow analyst Alton Stump said Dunkin' Brands' levered balance sheet, premium valuation, and slowing same-store sales and unit growth all make the company a less attractive acquisition target than 6 years ago when speculation started after JAB entered the coffee quick-serve category. He believes takeout speculation is primarily responsible for Dunkin' shares staying in the high $60 to low $70 range, though Stump sees an acquisition by JAB, or any other potential buyer, as unlikely in the foreseeable future, he tells investors. He maintains a Neutral rating on Dunkin' Brands shares.
