Shares of Shake Shack (SHAK) - Get Shake Shack Inc. Class A Report slumped after the burger chain's third-quarter revenue and same-store sales trailed expectations, even as adjusted earnings per share beat expectations.
Revenue increased 32% in the latest quarter from a year earlier, to $157.8 million. But analysts polled by Bloomberg anticipated $157.92 million, according to Yahoo.
And same-store sales climbed 2%, lagging analysts' forecast of a 2.9% gain. The 2% increase consisted of a 1.2% increase in customer traffic and a combined increase of 0.8% in price and sales volume.
Shake Shack's restaurant level operating margin fell to 23.1% in the third quarter from 25.8% a year ago. The decline stemmed from rising food and paper costs, the company said.
On the positive side, adjusted earnings per share totaled 26 cents in the latest quarter, compared to analysts' projection of 21 cents, according to Yahoo.
Net income surged to $11.4 million, or 31 cents a share, in the third quarter from $6.9 million, or 17 cents per share a year earlier.
Shake Shack also raised its full-year 2019 revenue guidance to a range of $592 million to $597 million from its prior range of $585 million to $590 million. But the company trimmed its full-year forecast for same-store sales growth to 1.5% from 2% previously.
"This has been the biggest development year in Shack history as we've grown our presence around the country and internationally in the new markets of Mainland China, Singapore, the Philippines and Mexico," Shake Shack CEO Randy Garutti said in a statement.
Shake Shack shares stood at $71.48 in after-hours trading, down 15.12%.
