Shake Shack (NYSE: SHAK) shares tumbled 6.43% in pre-market trading on Thursday following the release of its first-quarter 2025 financial results, which fell short of analyst expectations across multiple key metrics.

The fast-casual restaurant chain reported adjusted earnings per share of $0.14, missing the analyst consensus estimate of $0.16 by 12.5%. While this represents a 7.69% increase from the same period last year, it wasn't enough to satisfy investor expectations. Revenue for the quarter came in at $320.90 million, falling short of the estimated $328.08 million by 2.19%, despite showing a 10.46% year-over-year growth.

Other financial metrics also disappointed, with adjusted EBITDA at $40.7 million versus the expected $42.5 million, and adjusted net income at $6.4 million compared to the anticipated $7.42 million. The company's net income for the quarter stood at $4.5 million. These results suggest that while Shake Shack is growing, it's struggling to meet the high expectations set by analysts and investors, leading to the significant pre-market sell-off.
