Burlington Stores experienced a significant pre-market decline of 5.28% on Thursday, as the off-price retailer's stock came under pressure following the release of its first-quarter financial results.

The sell-off appears to be driven by Burlington's first-quarter earnings per share of $1.79, which came in slightly below the consensus analyst estimate of $1.80. While the company reported strong year-over-year growth with sales rising 14% and adjusted EPS increasing 26%, the earnings miss relative to expectations has triggered negative sentiment among investors.

Burlington provided guidance for the full fiscal year 2026, expecting adjusted EPS in the range of $11.45 to $11.80, compared to the IBES estimate of $11.60. The company also anticipates comparable store sales to increase 2% to 4% for the full year, with second-quarter comparable store sales expected to rise 1% to 3%.
