On September 8, Fabrinet rose 5.03% in regular trading, trading at $427.96 per share, with turnover of approximately $80.67 million. The rally was driven by a broad-based surge in the optical communication sector, fueled by intensifying AI infrastructure demand.

On the industry front, leading optical module manufacturers have issued bullish order guidance, with 1.6T optical modules accelerating volume ramp-up and AI data center demand for high-end optical communication equipment remaining robust. Order backlogs have extended into 2027 and beyond, reflecting a structural shift toward advance procurement across the AI infrastructure supply chain. The limited number of vendors capable of mass-producing 1.6T modules has further tightened supply-side dynamics.

Fabrinet's recently reported fiscal Q4 results provided additional fundamental support. Revenue reached a record $1.316 billion, up 45% year-over-year and above the consensus estimate of $1.275 billion. Data center revenue crossed 50% of total sales for the first time. Adjusted EPS came in at $4.10, beating estimates of $3.82. Q1 guidance of $1.38–$1.43 billion in revenue also exceeded the $1.32 billion consensus. CEO noted data center demand has \"no end in sight.\"
