On September 14, Fabrinet fell 5.44% in pre-market trading, trading at $393.0 per share, with turnover of $402,900. The stock declined alongside a broad selloff across the optical communications sector.

On the news front, executives from four leading global AI companies issued a rare unified call to slow the pace of frontier AI development. Anthropic CEO Dario Amodei emphasized the necessity of managing technological risks, while OpenAI CEO Sam Altman, SpaceX's Elon Musk, and Google DeepMind's Demis Hassabis echoed the sentiment. The coordinated remarks triggered market concerns over a potential contraction in semiconductor and optical component demand tied to AI infrastructure buildout. Additionally, Altman stated that OpenAI would not pursue an IPO in the current year, citing the evolving landscape around AI safety.

The optical communications sector fell broadly in pre-market trading, with Corning down over 6%, Marvell Technology, Lumentum, and Coherent each down over 5%, and Credo and Ciena declining nearly 5%. Brokerages generally interpreted the executives' statements not as a call to halt AI investment, but rather as a push to align model advancement with safety verification timelines, suggesting a potential delay rather than cancellation of demand.
