New York, New York--(Newsfile Corp. - June 4, 2026) - Levi & Korsinsky notifies investors that it has commenced an investigation into Shake Shack Inc. ("Shake Shack Inc.") (NYSE: SHAK) concerning potential violations of the federal securities laws.

Shake Shack shareholders lost approximately 9-10% of their investment today after the company cut Q2 FY 2026 revenue guidance to $415--$420 million, down from $424--$428 million issued just 26 days earlier. Same-shack sales growth guidance dropped from 3--5% to 2.5--3%, and restaurant-level profit margin expectations fell from 24--24.5% to 22--23%.

On May 7, 2026, CEO Rob Lynch told investors on Shake Shack's Q1 2026 earnings call: "We are reiterating our 2026 guidance for Shake-Shack sales, restaurant-level margins and our long-term financial targets." On the same call, management broadened adjusted EBITDA guidance to $230--$245 million. Today -- less than four weeks later -- several of those targets were reduced. Restaurant-level margins were cut by up to 150 basis points. Adjusted EBITDA guidance was lowered to $225--$235 million. While full-year same-Shak sales guidance remains intact, Q2's guidance was gutted with the floor becoming the celling as projections dropped from 3--5% to only 2.5-3%.
