The Springboard 2030 case, 18 quarters out
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 data/companies/glw/series.json 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.
Management's own plan, taken literally. Corning states an annualised run rate of $20 billion by the end of 2026, $30 billion by the end of 2028 and $40 billion by the end of 2030, and a 19% sales CAGR from Q4 2026 to Q4 2030. On the run-rate definition Corning's own filings prove - Q4 core sales times four, since Springboard 'launched with an annualized sales run rate of $13 billion' against Q4 2023 core sales of $3,272m - that resolves to Q4 2030 core sales of $10,000m. The base case gets to $9,129m, so this case adds 0.75 points a quarter to Optical Communications alone, which is where the brief's arithmetic puts the burden: the other four segments cannot carry it. It reaches a $40.0 billion run rate. What it does NOT do is change the exit multiple or the discount rate - it is worth $165.54 a share, so even delivering the plan in full leaves the stock roughly 8% undervalued rather than transformed, because at 28x today's EBITDA a great deal of the plan is already in the price.

What drives each segment
Optical Communications
Growth pathOptical fibre, cable and connectivity for carrier networks and, increasingly, AI data centres. This is where the Springboard thesis lives: 43.7% of core sales in the basis quarter, growing 32% year over year while the other four segments grew 7.5% combined. Three named hyperscaler agreements underwrite it - Meta (multiyear, up to $6 billion), Amazon (multiyear, multibillion-dollar) and NVIDIA, under which Corning expands US optical connectivity capacity 10x and US fibre capacity by more than 50% across three new plants in North Carolina and Texas. Operating leverage is visible: segment EBITDA margin went from 24.78% to 30.98% in a year.

Assumptions & reasoning
- The 30.98% basis margin is derived from the 10-Q segment table, not disclosed: net sales 2,072 less RD&E 92, depreciation 77 and other segment items 1,338 gives 565 of segment pretax income, plus the 77 of depreciation back = 642 of segment EBITDA.
- Corning names Enterprise Networks and Carrier Networks as the two streams but no longer publishes a dollar split for them - only growth rates (Enterprise +65% year over year in the basis quarter). No split is manufactured here.
- A capacity driver was considered and rejected. The NVIDIA release quantifies the expansion only as '10x' US optical connectivity capacity and 'more than 50%' US fibre capacity, with no base capacity, no completion dates, no utilisation and no revenue per unit; all three would have had to be invented.
- The Amazon and NVIDIA agreements were both announced inside the basis quarter, so almost none of their revenue is in the 2026 Q2 base. Neither has a disclosed annual profile, which is why no dated base shift is used either.
Glass Innovations
Growth pathDisplay glass for televisions, monitors and notebooks, plus Gorilla Glass cover materials and semiconductor-related glass - the former Display Technologies and Specialty Materials segments, combined effective Q1 2026. The most profitable segment at a 40.81% EBITDA margin and the most nearly flat at +1.4% year over year. Its job in the model is to be a large, stable, high-margin base, not a growth line.

Assumptions & reasoning
- The only vertical carrying seasonality. Ratio-to-centred-four-quarter-moving-average over 2023 Q1 - 2026 Q2 gives a 0.137 signal against a 0.067 largest window spread, and the two most recent Q3 windows agree at 1.054 and 1.055. The conservative factor set is used, which drops the 1.121 window of 2023 Q3 inflated by that year's display price increases.
- With seasonality present the engine deseasonalises the basis quarter before the driver runs, so the 0.4% growthQoQ is a deseasonalised trend rate, not a sequential change. The basis quarter divides by the Q2 factor of 1.012.
- This is the segment carrying a currency-basis discontinuity. Effective 1 April 2026 Corning replaced its constant-currency adjustment with an adjustment for hedged exposures and did not recast prior periods; it states the restatement would have raised prior-period growth rates for this segment and been immaterial elsewhere. Order of magnitude is roughly $50m on a $1,463m line, so the pre-2026 Q2 history here sits on a slightly different basis than the basis quarter.
- The 2023 figures Corning reports for Display Technologies plus Specialty Materials sum exactly to the recast FY2024 Glass Innovations total (3,872 + 2,018 = 5,890), which is what proves the combination - but the other three segments were not recast to 2023, so the model's shared history window starts at 2024 Q1.
Automotive
Growth pathCeramic substrates and particulate filters for emissions control, plus Automotive Glass Solutions. A mature, cyclical, cash-generative line with a 30.36% EBITDA margin and essentially no growth at +2.4% year over year. Its job in the model is ballast: it funds the build without being asked to grow into it.

Assumptions & reasoning
- Two years of segment EBITDA margin sit in a 28.7-30.7% band with no trend, so the terminal margin is held mid-band rather than extended in either direction.
- Terminal capex intensity is set to the FY2025 rate of 4.24% rounded to 4.0%, not to the 3.40% of one light quarter, because 16 of capital spending on 471 of sales is a quarter of maintenance-only spend rather than a run rate.
- The segment was created on 1 January 2025 by moving Automotive Glass Solutions in with Environmental Technologies and Corning did not recast 2023, so only ten quarters exist on this definition - which is also what sets the model's shared history window.
Solar
Growth pathHemlock Semiconductor polysilicon plus Corning's new US solar wafer and module manufacturing, made a reported segment in Q1 2026. Sales grew 90% year over year to $438m and management states a level target of 'more than $3 billion' of revenue with strong profit and cash flow, with no date attached. The basis quarter is depressed by a disclosed extended maintenance shutdown and equipment upgrade at the solar wafer facility that added about $30m of expense and produced a $7m segment net loss.

Assumptions & reasoning
- Management's words on the profitability path, quoted whole so the qualifier survives: 'We also expect an improving impact on earnings from Solar starting in Q3 as our ramp continues, building toward a revenue stream of more than $3 billion with strong profit and cash flow.' No date is attached to the $3 billion, so the date in this model is assumed, not disclosed.
- The 16.44% basis EBITDA margin is flattered by depreciation: the segment was pretax NEGATIVE at -5 in the quarter and the positive EBITDA is entirely the $77m depreciation add-back. The margin glide to 28% is therefore a recovery assumption, not an extension of a trend.
- Seasonality was measured and rejected. The arithmetic looks seasonal - a 0.413 signal against a 0.092 largest window spread - but the shape is a plant ramp: sales ran flat near $200m through 2024 then 206, 231, 319, 475, 370, 438. A centred moving average lags an accelerating series, which mechanically inflates the late Q4 ratios, and both Q4 windows sit inside the ramp.
- About 8% of consolidated net income is the Hemlock Semiconductor non-controlling interest and it sits inside this segment. The model values enterprise free cash flow before that minority, so per-share fair value is overstated to the extent the minority keeps growing with the line.
Life Sciences and Emerging Growth Businesses
Growth pathThe residual grouping left after the Q1 2026 restructure: laboratory consumables and pharmaceutical technologies plus other emerging businesses. Declining and loss-making - $294m of sales down 15% year over year and a $21m segment net loss, the only segment in outright decline. In the model it is a small drag, not a growth line.

Assumptions & reasoning
- The -1.36% basis EBITDA margin is derived: net sales 294 less RD&E 27, depreciation 23 and other segment items 271 is -27 of segment pretax, plus 23 of depreciation back = -4. The segment lost money at the EBITDA line in the basis quarter.
- The 8% terminal margin is a partial recovery toward the 9.86% this line earned in 2025 Q2. No management target exists for this segment, so it is an assumption and the single least evidenced number in the model - though on 3% of sales it moves fair value by cents.
- Seasonality was measured and rejected: the whole 0.251 signal rests on one Q2 window of 1.139, and the following year contradicts it - if Q2 were genuinely 13% above trend, 2026 Q2 would not have come in 15% below the prior year.
- Corning does not split Life Sciences from Emerging Growth Businesses inside this line, so the source of the decline is not attributable and no sub-split is attempted.

The plan, as stated
- Jul 28, 2026 The company's internal Springboard Plan is to grow sales to an annualized run rate of $20 billion by the end of 2026, $30 billion by the end of 2028, and $40 billion by the end of 2030.
- Jul 28, 2026 The company expects to deliver a sales CAGR of 19% from Q4 2026 to Q4 2030 - while growing earnings faster than sales, with significantly higher returns on invested capital and substantially more free cash flow.
What the run rate means
From cash flow to fair value
| Present value of free cash flow, 18 quarters | $17.97B |
| Terminal-year revenue | $37.69B |
| Terminal-year EBITDA | $11.51B |
| Exit multiple, on ebitda | 17.0x |
| Terminal value | $195.71B |
| Discounted at 9.0% a year, terminal value becomes | $132.80B |
| Enterprise value | $150.77B |
| Net cash | -$5.92B |
| Equity value | $144.85B |
| Shares | 0.88B |
| Fair value per share | $165.54 |
| Against the current price of $152.80 | +8% |
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 $152.80 the market is paying 15.6x terminal-year revenue, holding every other assumption on this page fixed. That is the number to argue about.
