Shares of Shake Shack Inc. (SHAK) suffered a steep decline on Thursday, falling as much as 30.4% after the company reported a first-quarter net loss, missed revenue expectations, and announced a change in its chief financial officer. The stock last traded at $69.24, a drop of $27.27 from the prior close, marking the largest single-day percentage fall since 2015, according to Barron's.
Quarterly Results Miss Estimates
For the first quarter ended March 25, 2026, Shake Shack reported revenue of $366.7 million, a 14.3% increase year-over-year but below the $371.9 million consensus estimate from analysts polled by LSEG via Reuters. The company swung to an operating loss of $2.6 million, compared to operating income of $2.8 million in the year-ago period. Net loss attributable to the company was $290,000, or 1 cent per diluted share. Adjusted EBITDA declined 9.3% to approximately $37.0 million.
Margins Squeezed by Beef Costs and Spending
Rising beef prices, which saw inflation in the low teens, pushed food and paper costs to 28.3% of Shack sales, 50 basis points higher than last year. General and administrative expenses jumped to $53.6 million, driven by increased spending on marketing, technology, and hiring. Other operating expenses also rose, including higher repair and maintenance costs tied to supporting new locations. Same-Shack sales, which track locations open at least 24 months, increased 4.6%, with guest traffic up 1.4%. CEO Rob Lynch attributed a 240 basis point drag on comparable sales to adverse weather but noted that "underlying sales and traffic momentum remained strong."
Expansion Plans Intact Despite Headwinds
Despite the margin pressure, Shake Shack opened a record 17 new company-operated locations in the first quarter, its largest first-quarter expansion ever. The company raised its 2026 guidance for company-run openings to 60 to 65, up from the previous range of 55 to 60. For the second quarter, management expects revenue between $424 million and $428 million, with Same-Shack sales growth of 3% to 5%. Full-year 2026 projections call for revenue of $1.6 billion to $1.7 billion, net income of $50 million to $60 million, and adjusted EBITDA of $230 million to $245 million.
New CFO Appointed
Michelle Hook will assume the role of chief financial officer on May 11, 2026. Hook previously served as CFO at Portillo's and spent over 17 years at Domino's. She will oversee finance, tax, treasury, investor relations, and reporting. Lynch described her as bringing "deep restaurant industry expertise," while Hook highlighted Shake Shack's "disciplined approach to building a beloved brand."
Broader Industry Context
The challenges at Shake Shack echo trends across the restaurant sector. McDonald's reported softer sales growth for the quarter, while Chipotle Mexican Grill and Restaurant Brands International both noted higher beef costs. Michael Gunther, senior vice president at Consumer Edge, pointed to "broader signs of consumer strain" and emphasized the importance of monitoring how Shake Shack manages elevated beef costs.
Analyst Views and Risks
William Blair analyst Sharon Zackfia told Barron's that the selloff appeared excessive, arguing that Shake Shack's growth prospects remain "one of the strongest and most proven" in the emerging restaurant space. However, the company faces risks including delayed store openings, supply chain disruptions, labor cost inflation, tariffs, and ongoing digital investment needs. April Same-Shack sales declined 0.6%, affected by the timing of Easter and spring break. Management is counting on a boost from the new Smoky BBQ menu, a boneless baby back rib sandwich, and World Cup-driven traffic in key markets. Investors will be watching closely to see if the chain can sustain its expansion while protecting margins.
