On September 9, FormFactor rose 5.28% in regular trading, trading at $115.66/share, with turnover of $53.67 million. The rally was driven by news that Samsung Electronics has selected FormFactor's probe station for its silicon photonics technology development program, specifically for testing silicon photonic integrated circuit wafers.

Notably, TSMC had previously adopted the same category of FormFactor equipment, making Samsung's adoption a significant milestone. FormFactor now counts both of the world's leading foundry giants as clients in the cutting-edge silicon photonics domain, which is expected to further solidify its leadership position in the semiconductor test equipment market. The win also follows a strong second quarter in which FormFactor posted revenue of $258.2 million, well above the $240 million consensus estimate, with adjusted EPS of $0.82 beating the $0.61 estimate by over 34%. The company also announced a strategic partnership with Keystone MicroTech to jointly advance next-generation semiconductor technologies.
