Impairment case

Named cause: the transceiver ASP deflation LITE itself discloses, arriving before its own 1.6T product does, against a share count that grows as the stock falls. Three mechanisms compound, and each is sourced to LITE's own words: 1. ASPs are already falling. The 10-Q attributes cloud-transceiver growth to *"an increase in shipment volume, partially offset by lower average selling prices."* Volume growth of 77–121% is masking price erosion right now, at the top of the cycle. 2. LITE's own 1.6T transceivers do not ship until mid-CY2026, a year behind COHR, and the industry ramp gates on 102.4T s
