The Bear case, 18 quarters out

Model as of

Each segment is projected from its own operating driver, rolled up into consolidated cash flow, and discounted back to a fair value per share. The assumptions below are editable — change them and every number on this page moves with them.

Every revenue figure in this model is on Corning's non-GAAP CORE basis, because that is the basis of the reported segment table: the five segments sum to $4,738m in 2026 Q2, not to the $4,505m of GAAP net sales, and the $233m difference is the adjustment for hedged exposures. Guidance and the Nasdaq consensus are on the same core basis. Anyone reconciling these verticals against the GAAP revenue in our stored series will find that gap and it is not a modelling error. The five verticals are Corning's own reported segments and sum exactly to disclosed core sales in every one of the ten quarters shown. History starts at 2024 Q1 because the Automotive and Solar segments only exist on this definition from the 2026 Q1 recast exhibit backwards to 2024; Optical Communications and Glass Innovations have disclosed 2023 quarters but the other three do not, and padding them with zeros would invent a consolidated 2023 that never happened. Segment EBITDA margins and capex intensities are DERIVED from the 10-Q segment table by adding depreciation back to segment pretax income; they are not disclosed margins, and segment income is struck after a notional tax and before corporate unallocated amounts, which is why a 1.96% corporate overhead line bridges the five segments to core EBITDA. All forward growth rates, margin glides, capital intensities and the exit multiple are ASSUMED. Corning has published no segment-level 2028 or 2030 target - the Springboard milestones are consolidated only - so the allocation of the plan across segments is a modelling judgement, stated as such in the Springboard 2030 case rather than presented as guidance.

Fair value per share $89.57 −42% against $153.76

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.

Corning trades at 28.3x TTM core EBITDA - $139,620m of enterprise value over $4,930m of TTM core EBITDA - and 7.9x TTM core sales. That is a growth multiple, so the terminal assumption is the single most sensitive input in this model. The base case exits at 17x, well below today's 28.3x, on the view that the AI-cycle premium compresses once the growth has actually been delivered. The bear case uses 13x, roughly where diversified materials trade, and the bull case 22x, which still assumes some premium survives to 2030. At a 9% discount rate the terminal value is most of the enterprise value, so the exit multiple matters more than any single driver.

Read the other way round: at $153.76 the market is paying 23.4x terminal-year EBITDA, holding every other assumption on this page fixed. That is the number to argue about.
