SemiLEDs shares surge 13.40% after hours on 104% YoY revenue jump driven by equipment purchase orders.

SemiLEDs (NASDAQ: LEDS) surged 13.40% in after-hours trading following the release of its Q1 2026 earnings report, which highlighted a 104% year-over-year revenue increase to $2.6 million driven by buy-sell equipment purchase orders. While sequential revenue declined from $13.2 million, investors focused on the improved net loss of $742,000 (from $1.2 million in Q4 2025) and a narrowed operating margin loss to 39%. The 10-Q filing further emphasized growth in niche markets like UV LED and horticultural lighting, alongside management’s focus on higher-margin product sales. Despite mixed sequential performance, the year-over-year revenue surge and margin improvements likely fueled optimism about the company’s strategic shift toward specialized applications, aligning with the post-earnings price jump.
