Shake Shack reported double-digit sales growth in the fourth quarter, supported by network expansion and continued comparable sales gains.

The burger chain’s revenue jumped 21.9 per cent year over year to $400.5 million for the quarter ended December 31, including $385.3 million in same-store sales and $15.2 million in licensing revenue. 

Meanwhile, operating income reached $18.7 million and net income totalled $13 million, while adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) was $56.1 million.

The company opened 15 company-operated restaurants and 17 licensed locations during the quarter.

CEO Randy Garutti said the company’s operational focus helped drive performance despite economic pressures.

“Our strong fourth-quarter performance underscores our commitment to operational excellence and culinary innovation,” he said.

Shake Shack continued expanding its footprint, opening 45 company-operated restaurants and 40 licensed locations last year, entering new domestic markets including Buffalo and Oklahoma City, and expanding into Hawaii.

The company also partnered with Penn Entertainment to open locations in casinos.

Globally, the fast food chain signed new agreements in Vietnam and Panama.

CFO Tara Comonte said improved margins and cost control supported the results.

“We are pleased with our margin expansion and cost management efforts, which have positioned us well for future growth,” she said.
