Shares of Chipotle Mexican Grill plunged 38.6% in 2025, driven by weak customer traffic and flat same-store sales in the first three quarters (0% in Q1, 4% in Q2 and 0% in Q3 versus the prior year). Despite opening new outlets to reach over 4,000 locations in North America, concerns over market saturation prompted investors to reduce exposure, making Chipotle one of the worst-performing names in the restaurant sector last year.

Rising input costs outpaced sales growth, causing operating margin to slip from 17.0% to 16.4% over the trailing twelve months. The mismatch between labor and food inflation and minimal same-store sales gains eroded profitability, with gross margins also tightening to 22.7%. Management has signaled that unless traffic trends improve, further margin compression may continue to weigh on earnings per share.

In early 2026, Chipotle shares have recovered 8.5% year-to-date, but the stock still trades at a 36 P/E ratio, well above the S&P 500 average of 31. While the company plans incremental unit growth in North America and expansion into Europe, the Middle East and its first Mexican location, the key risk remains stagnant same-store sales. Without a clear rebound in customer visits, the premium valuation offers limited margin for error, suggesting investors should remain cautious.
