GrowGeneration shares surge 13.77% after-hours on Q3 earnings beat and 40% proprietary brand mix target by 2026.

GrowGeneration surged 13.77% in after-hours trading following its Q3 2025 earnings report, which showed a 4-cent loss (beating the 8-cent consensus) and $47.25 million in revenue (exceeding expectations of $41.43 million). The results, coupled with improved margins and a positive EBITDA outlook, signaled better-than-expected operational performance despite a broader 26.2% decline in the stock for the quarter. Additionally, the company highlighted progress toward a 40% proprietary brand mix by 2026, reinforcing long-term growth potential. While the stock remains down 18.3% year-to-date, the earnings beat and strategic focus on margin expansion likely drove the after-hours rally.
