 Fast-casual burger chain BurgerFi is about to go public after reaching a 100 million merger-acquisition agreement with Opes Acquisition NASDAQ: OPES, a so-called blank check company created to use investor money to buy companies. When the deal is completed, which is expected to be sometime before Nov. 1, BurgerFi will be listed on the Nasdaq exchange under the ticker symbol BFI. The fast-casual space was looking for the next new thing to capitalize on the strength of Chipotle Mexican Grill, and though Shake Shack NYSE: SHAK was not the first better-burger shop, its IPO in 2015 seemed to kick the concept into high gear.
