Ross Stores stock rose in Friday premarket trading after the off-price retailer reported strong second-quarter results for fiscal 2026, with sales up 13% to $6.3 billion and net income rising to $851 million, driven by higher customer traffic and tariff refunds. The company beat estimates on revenue and earnings and raised its full-year outlook. Second-quarter revenue was about $6.27 billion versus a $6.18 billion estimate, with sales up 13% year over year to roughly $6.3 billion and comparable-store sales up 10% on stronger traffic. Earnings reached $2.66 per share, above the $1.94 consensus. Gross margin expanded 625 basis points, including a 405-basis-point benefit from tariff refunds, while operating margin rose 610 basis points, or 205 basis points excluding refunds. CEO Jim Conroy said Ross has grown faster than its two major off-price rivals over the past four quarters and is capturing share. The company lifted 2026 earnings guidance to $8.61–$8.77 per share from $7.50–$7.74, above the $7.79 analyst estimate, guided third-quarter sales up 9%–11%, and raised its 2026 store-opening target to 115. Shares were up 8.11% at $247.56 premarket, approaching a $257.00 52-week high.
