Interface, Inc. shares fell 18.72% on Monday to $30.74 after the company cut its 2026 sales outlook, according to MT Newswires. The drop erased nearly a fifth of the company’s value in a single session.

Guidance cut triggers sell-off

Interface reduced its full-year sales forecast after reporting third-quarter earnings that came in below analyst estimates, according to StockStory. The company also discussed margin expansion and double-digit earnings per share growth during its Q3 earnings call, as noted by GuruFocus and Moby.

MarketBeat reported that management addressed the results directly during the call, though the specific details of the revised guidance were not included in the available summaries. Simply Wall St. noted the stock could be undervalued after the outlook cut, but the immediate market reaction was a sharp decline.

Stock underperforms peers

By Falling Shares' measure, almost all of the move was company-specific, with the market and sector contributing negligible changes. The S&P 500 rose 0.3% in the previous session, while the US Consumer Discretionary sector fell 0.1%.

The stock has lost 16.5% over the past five days and 11.7% over the last month. Over the past year, shares have gained 18.1%, though they remain 23.5% below their 52-week high of $40.84.
