Corning Reiterates $40 Billion Sales Target by 2030, Details How AI Scale-Up Could Multiply Optical Content Per GPU by 10x
Q2 2026 earnings call, July 28, 2026
Corning delivered a second quarter that beat its own guidance across the board, with sales up 17% year-over-year to $4.74 billion and core EPS up 30% to $0.78. But the more important story for investors is the company's insistence that nothing has changed in its long-term artificial intelligence thesis despite two months of industry chatter about supply chain readiness and potential delays in optical scale-up. CEO Wendell Weeks used the call to reiterate, and add technical color to, the "Springboard 20-30-40" plan first laid out at Corning's May investor day: an annualized sales 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.
Scale-Up Optics: The 10x Content Opportunity
The most detailed new disclosure on the call concerned the mechanics of how Corning's optical content per GPU could scale as AI data center architecture evolves. Weeks walked through three technical drivers he says will let Corning grow faster than GPU unit growth itself. The first is cluster size: once AI clusters exceed 130,000 GPUs, network designs require a third optical layer instead of two, translating into 50% more optical content per GPU for the largest clusters. The second driver, bandwidth growth, is roughly neutral to Corning under its current planning assumptions, since higher SerDes rates in the Rubin generation offset the need for more fiber lanes.
The third driver, scale-up optics, is where Corning sees the largest and least predictable opportunity. Today, scale-up networking inside AI racks is done entirely with copper. Weeks pointed to NVIDIA's recently announced Vera Rubin Ultra configuration, in which 576 GPUs are connected across 8 racks using copper within racks and optical connections between them, as evidence that the industry is already taking "a transition step to optical." Corning's own math shows the extremes: in an all-copper world, content per GPU stays where it is today; in a fully optical scale-up world, content could reach 160 fibers per GPU, which Weeks called "10x the amount of fibers of the current scale-out network." He was careful to note that the real outcome will land somewhere between those bookends, and that Corning does not have visibility into what percentage of ports NVIDIA and others will ultimately make optical. Combining all three drivers, Corning's internal planning assumes optical content per GPU in its Enterprise segment rises 1.3 to 1.5 times by 2028, with the potential for a much steeper increase into 2030 as scale-up adoption compounds.
Photonics: A New $10 Billion Platform From Scratch
Alongside the Enterprise optical business, Corning is building an entirely new Photonics market access platform aimed at supplying passive optical components inside AI servers, an area where the company previously had zero content. As co-packaged and near-package optics designs replace pluggable transceivers to improve latency, density, power draw and reliability, Corning is positioning to sell the components that create, modulate and deliver light inside the box. Management reiterated the $10 billion Photonics revenue opportunity by 2030 but declined to give a specific 2027 figure, pushing back on analysts who have tried to back into a $1 billion-plus estimate for next year. "We'll update each quarter as we go, and we're giving you the long-term Photonics plan," Weeks told UBS analyst Josh Spector, adding that fiber array unit harnesses, an area of investor confusion on the call, are just one component of the broader Photonics content opportunity captured in that $10 billion figure.
Two Versions of the Plan: Internal Ambition vs. Investor-Facing Confidence
Corning continues to run two separate growth targets, a distinction management spent considerable time clarifying. The internal Springboard plan, built from individual business unit forecasts at a 70% confidence interval, targets a $40 billion run rate by 2030. The "high confidence plan" shared with investors, after corporate-level risk adjustments for macro conditions, government policy and adoption timing uncertainty, calls for $35 billion by 2030 and $27 billion by 2028. CFO Ed Schlesinger noted that under either scenario the company expects to double its size from 2025 levels by the end of the decade, with the biggest swing factor being the pace of optical scale-up adoption inside AI factories. "The overall size of the opportunity is dramatic, but calling the timing is challenging," Schlesinger said, adding that Corning will "get smarter about this with each passing month."
Optical Communications Segment Is Already Delivering
The numbers underneath the AI narrative were strong. Optical Communications sales rose 32% year-over-year to $2.07 billion, with net income up 77% to $438 million and net profit after tax margin hitting a record 21% of sales. Within that, Enterprise sales, the piece most tied to AI infrastructure, grew 65% year-over-year to $1.27 billion, and the portion of Enterprise sales tied to generative AI data centers nearly doubled. Weeks was explicit that this growth reflects scale-out demand only. "This is all just scale-out. We're not yet seeing scale-up or Photonics in our results," he said, underscoring that the more dramatic content expansion opportunities are still ahead of the company rather than already priced into current results.
Margin Expansion Driven by Innovation, Not Just Price
Wolfe Research analyst George Notter pressed management on long-term agreement coverage and pricing power in optical. Weeks confirmed that long-term agreements will become "the lion's share" of the optical business going forward, as Corning uses these contracts to share risk on major capacity expansions with customers including Meta, NVIDIA and Amazon. On pricing, Weeks pushed back on the idea that margin gains are simply a function of raising fiber prices. "We create value by delivering innovations in fiber, cable and connectivity to dramatically reduce our customers' cost, increase their speed of deployment or increase the reliability of their networks. And then when we create value for our customers with our innovations, we get to keep a portion of that value," he said, attributing the segment's profitability surge primarily to mix shift toward higher-density, more innovative product lines rather than list-price increases.
Solar Ramping Back Up After Planned Shutdown
Solar sales grew 90% year-over-year to $438 million, though the segment posted a $7 million net loss after absorbing an extra $30 million of expense tied to a planned maintenance shutdown and power system upgrade at its wafer facility. Management expects sales and profitability to improve starting in the third quarter now that the shutdown is complete. Corning reiterated its plan to build solar into a $3 billion revenue stream with above-corporate-average profitability, citing its position as the only U.S.-based polysilicon and wafer manufacturer at a time when policy is favoring domestic solar content. In response to a question from Susquehanna's Mehdi Hosseini, Weeks also confirmed Corning intends to shift more of its polysilicon output toward higher-margin electronic-grade material used in semiconductor manufacturing, though he cautioned this will remain a small piece of overall volume.
Guidance Implies Hitting the 2026 Target a Quarter Early
For the third quarter, Corning guided sales to grow approximately 16% year-over-year to a range of $4.9 billion to $5 billion, with core EPS growth of approximately 28% to a range of $0.85 to $0.89. Schlesinger pushed back directly on a Bank of America question suggesting the guide implied deceleration, saying the third-quarter outlook is consistent with second-quarter growth rates and that the company still expects its growth rate to accelerate toward a 19% CAGR from the fourth quarter of 2026 through 2030. Notably, Weeks pointed out that the third-quarter guide implies Corning could reach its $20 billion annualized run rate target a quarter ahead of the original year-end 2026 schedule, though he stopped short of formally upgrading the target again so soon after the May investor day. Capital expenditure is set to rise to approximately $2 billion for the year to support the optical buildout, while management said it still expects operating margin to run at or above 20% and free cash flow to grow significantly even as investment ramps.
