SiTime shares surge 12.52% after-hours as new GNSS-secure timing solution boosts defense and aerospace markets.

SiTime surged 12.52% in after-hours trading following the launch of its ENDR-TTT Endura Super-TCXO, a precision timing solution engineered to enhance GNSS resilience against jamming and spoofing. The product, targeting aerospace, defense, and industrial markets, offers 20x longer holdover and 20x better PNT accuracy compared to prior TCXOs, alongside superior shock resistance and temperature stability. These features position SiTime to capitalize on growing demand for secure timing systems in high-threat environments. While an insider sale by VP Ahamad (4,000 shares, $1.2M) introduced short-term uncertainty, the product’s strategic relevance to critical infrastructure and defense applications overshadowed this event. The rally reflects investor confidence in SiTime’s innovation to address GNSS vulnerabilities, aligning with the stock’s significant after-hours jump.
