Anderson described typical engineering qualification milestones, sized multi-rail at $2 billion+, highlighted Thermadite material offering 2x to 5x better heat transfer than copper, and thermoelectric generators for waste heat recovery.

Anderson emphasized breadth across CW lasers, VCSELs, external laser source modules, isolators, thermoelectric coolers, fiber attach units, and micro-lens arrays. Most customers leveraging majority of the portfolio.

Jim confirmed no significant financial difference between EML and silicon photonics 1.6T. Customer application drives mix. Ramping InP capacity for both transceiver demand and high-power CW laser demand for CPO.

Jim noted 6-month wafer-start-to-shipment cycle means benefits just starting. By year-end, half of internal capacity at roughly half the cost. Sherri detailed 470bp gross margin improvement since FY2024 from cost reductions, yield, and pricing optimization.

Jim reported stable expected transceiver pricing with supply-constrained market as positive dynamic. Sherri highlighted pricing optimization contributing to 70bp sequential and 200bp YoY gross margin improvement.

Jim confirmed multiple customers accelerating 1.6T timelines. Expects 800G to still grow YoY while 1.6T ramps on top. Highlighted being only company to demonstrate 1.6T with three different laser technologies.

Jim deferred share quantification but noted faster adoption cycles with overlapping 800G/1.6T ramps; expects small early adopter group expanding rapidly as seen with 800G.

Sherri confirmed tariff impact factored into guidance as not significant; cost reductions company-wide while pricing optimization primarily in industrial segments.

Sherri highlighted volume, yield improvements, and lower costs in datacom as Q2 drivers, deferred long-term model details to May Investor Day.

Jim declined to specify technology selection for competitive reasons, emphasized multi-technology approach as key competitive advantage recognized by customers.

Bren indicated stability around $3 billion for at least the first half but declined to comment on second half specifics.

Bren detailed rising process control intensity at N2, HBM driving adoption due to less redundancy and larger die, and accelerating advanced packaging growth.

CEO noted the shift to contract manufacturing is margin-accretive since CM efficiency on common components more than offsets fees. Described the transition as early innings.

CEO estimated transceiver supply-demand imbalance in the 30% range but did not give a precise figure. Confirmed 1.6T margins are structurally better than 800-gig, with room for Lumentum-specific improvement.

Archer confirmed the cycle repeats off a larger installed base but conceded the next wave has not been quantified, calling it an action item.

Explained the convergence of DRAM requirements toward leading-edge foundry logic and named the specific applications driving wins.

Kris provided segment-level breakdown: Edge IoT improving, networking/infrastructure still has excess inventory, automotive/industrial undershipping demand.

Kris outlined FY25 gross margin flattish due to slower broad markets mix tailwind. Drivers: utilization, cost reductions, broad markets mix. Long-term targets: 50% then 53%.
