Research Frontiers surged 16.43% in after-hours trading following its Q3 2025 earnings report, which highlighted the commercial rollout of an SPD-SmartGlass retrofit window system at GlassBuild 2025, sequential growth in automotive royalties (including Ferrari-related revenue set for full Q4 recognition), and industry recognition at key conferences. The company emphasized its debt-free status, $1.13 million in cash, and positive market reception of its technology, with CEO Joseph Harary noting global momentum and scalability. These developments, coupled with forward-looking guidance on continued product innovation and royalty growth, likely drove investor optimism, aligning with the significant post-earnings price increase.
