Bolt Projects shares surge 15.88% after hours as Q3 gross profit outlook doubles to $1.0M and margins hit 16%.

Bolt Projects Holdings surged 15.88% in after-hours trading following the release of its Q3 2025 financial results, which highlighted a revised gross profit outlook of over $1.0 million (up from $0.5 million) and Q4 gross margins exceeding 40%. The report emphasized sequential gross margin expansion to 16% in Q3, driven by cost reductions and pricing discipline, alongside strategic partnerships such as the collaboration with amika for a first-of-its-kind Vegan Silk™ aerosol application. New customer acquisitions, including a global beauty conglomerate, and product launches like RAD-REMEDY underscored market traction. Operational scalability was reinforced by rapid cost improvements, a Silver-level EcoVadis sustainability rating, and the successful scaling of XL-Silk. Financing activities, including a $4.3 million private placement and a $30 million convertible debt facility, further strengthened liquidity. These developments collectively signaled progress toward profitability and scalability, aligning with the stock’s sharp post-earnings rally.
