Lumentum reported fiscal Q4 2026 revenue of $1.006 billion, up 24.5% QoQ and 109.3% YoY. Components revenue reached $649.4 million, rising 102.7% YoY. The company said increasing AI compute speed and bandwidth requirements are driving greater use of optical connectivity in datacenters, alongside accelerating 1.6T cloud-module adoption and growing demand for ultra-high-power CPO lasers. Its fiscal Q1 2027 revenue guidance midpoint reached $1.25 billion. SMM views the expansion of high-speed optical modules and lasers as providing downstream demand support for InP and high-purity indium. However, Lumentum did not disclose InP-specific revenue, shipments or indium consumption, preventing a quantitative estimate of demand growth.

Mongolia’s National Statistics Office reported molybdenum concentrate output, on a contained-metal basis, of 382.0 tonnes in August 2026, down 10.0% MoM but up 8.7% YoY. Jan–Aug output totaled 3,672.5 tonnes, up 9.2% YoY. August production was 42.4 tonnes below July but 30.5 tonnes above a year earlier. Mongolia’s cumulative supply therefore remained ahead of 2025 despite softer short-term output. The table provides no company-level breakdown, so the cause of the monthly decline cannot be confirmed.
