LandMark Optoelectronics Corporation (LMOC) reported strong fourth-quarter 2025 performance, driven by a sharp ramp in silicon photonics (SiPh) shipments, with all three profitability metrics rising sequentially. The company expects silicon photonics demand to remain robust, forecasting faster quarter-over-quarter revenue growth in the first quarter of 2026 than in the previous quarter. Shipments are set to sustain threefold growth, supported by planned capital spending of about NT$700 million (US$22.3 million) to expand capacity ahead of demand growth in the second half of 2027.
