The AI line is the whole company and everything else is flat or shrinking. In the basis quarter the four non-Optical segments together produced $2,666m against $2,479m a year earlier - 7.5% growth - while Solar posted a segment net loss and Life Sciences and Emerging Growth Businesses fell 15% year over year into a $21m loss. Corning has never published a segment-level 2030 target, so the $40 billion rests on an Optical Communications line that would have to roughly triple. Meanwhile the buyback has stopped and first-half capex is up 46% year over year to $754m. Optical's own recent history shows the downside: carrier de-stocking took it from $1,125m in 2023 Q1 to $903m in 2023 Q4 in four quarters. This case runs Optical 1.5 points a quarter slower, Solar the same, margins two points lower, and exits at 13x on a 10% discount rate. It reaches a $29.9 billion run rate at the end of 2030 - short of the $30 billion 2028 milestone, let alone $40 billion.
