According to Reuters, Shake Shack is preparing for an initial public offering.
The report said that the New York City-based burger chain's majority owners have been interviewing investment banks in recent weeks.
Reuters said Shake Shack's earnings are supposed to be around $20 million next year.
Shake Shack's IPO would come as fast-casual restaurants like Red Robin have been under pressure, while shares of Mexican fast food chain Chipotle have been among the market's best performing stocks.
