Danny Meyer’s Shake Shack blew away Wall Street’s expectations in the second quarter, posting adjusted net profits that more than tripled to $3.4 million, or 9 cents a share, from last year.

Analysts were expecting profits of just 3 cents.

Shares soared as much as 10 percent, to nearly $78, in after-hours trading.

Revenue in the period jumped 74.7 percent, to $48.5 million — well over the $43 million that was forecast.

Same-store sales gained 12.9 percent.

“I could not be more proud of my team and what they accomplished this quarter,” CEO Randy Garutti said during a conference call Monday with analysts.

Shake Shack plans to open 12 domestic and five international locations every year and forecasts revenue of $171 million to $174 million for fiscal 2015.
