Burger King is banking on its viral “Whopper Whopper” jingle to lift sales as part of the flagging fast-food chain’s turnaround plan, as broader economic uncertainty pushed two big franchisees into bankruptcy.

The ad, which aired incessantly during the National Football League playoffs in January, has drawn younger customers to its restaurants. The company released the earworm on TikTok, so fans could make their own remixes, and Spotify, where it has been streamed more than 3 million times.

Burger King’s parent company Restaurant Brands International (RBI), McDonald’s Corp (MCD.N), Chipotle Mexican Grill Inc (CMG.N) and other big chains start reporting first-quarter sales and profits next week. Investors will look for signs that the restaurant business is stable as U.S. consumer sales start slipping.

Restaurants – including RBI – are likely to “speak glowingly of this past quarter’s results and strike a cautiously optimistic tone regarding current quarter trends,” said Citi analyst Jon Tower in a note on Friday.

Burger King’s jingle – along with a broader “You Rule” marketing campaign, new restaurant technology and store renovations – is part of its $400 million “Reclaim the Flame” plan to reverse its loss of customers to other chains, revive run-down restaurants, streamline overly complicated menus and operations and draw more young customers.

Another strategy: adding franchisees. Unlike other fast-food chains like Subway which are consolidating restaurant ownership among fewer franchisees, Burger King is expanding the number of owners in its system.

The brand currently has about 375 U.S. operators – five to ten more than last year – and has a “robust pipeline” of potential new franchisees, Curtis said.

This year, two large U.S. Burger King franchisees that run more than 200 locations across at least 10 states have filed for bankruptcy, citing poor sales atop surging costs for labor and goods.

Locations involved in those bankruptcies will likely be split up among additional franchisees.

The company will also consider intervening to help certain franchisees if it knows operators are “100% committed and are in their restaurants consistently,” Curtis said. The ideal operator would run about 50 or 60 restaurants in their community.

According to Citi’s Tower, any lift to Burger King’s share prices could be “limited” unless it proves its turnaround plan is advancing with data showing the “broad financial health of franchisees that addresses concerns about additional bankruptcies/closures.”
