1. Q2 FY2026 Results and Q3 Guidance

Lumentum delivered Q2 revenue of $665.5 million, marking a 65.5% increase year-over-year, driven by surging demand for datacom and telecom products. Management issued Q3 guidance of $780 million to $830 million, implying more than 85% year-over-year growth and reflecting strong order momentum.

2. S&P 500 Inclusion and Market Impact

Lumentum was added to the S&P 500 on March 6, prompting index funds to accumulate shares and providing a mechanical buying tailwind. This inclusion has bolstered liquidity and supported the recent 8% stock jump.

3. Strategic Investment and Production Ramp

NVIDIA invested $2 billion in Lumentum, underscoring confidence in optical infrastructure as an AI scaling bottleneck. The company is expanding electro-absorption modulated laser production and expects to ship a $400 million optical circuit switch backlog in the second half of 2026.
