Corning Incorporated (GLW) Earnings Call Transcript & Summary
September 9, 2026
What were the key takeaways from Corning Incorporated's September 9, 2026 earnings call?
In the third quarter of fiscal 2026, Corning Incorporated (GLW:US) reported strong performance, driven by a significant multiyear deal with Verizon for a long-haul network, which management described as a 'multibillion-dollar deal.' Revenue is expected to reach a $20 billion run rate a quarter earlier than previously anticipated, with management indicating high teens year-on-year growth rates. The company maintained its guidance for the fourth quarter, projecting sequential growth and confidence in reaching their long-term financial targets, although no updates were provided for the $30 billion and $40 billion targets for 2028 and 2030, respectively.
What topics did Corning Incorporated cover?
- Verizon Deal: Corning announced a significant multiyear agreement with Verizon to support their long-haul network, which management highlighted as a 'great relationship' that underpins their growth strategy. This deal is expected to accelerate Corning's data center interconnect opportunity, previously estimated at $1 billion annually by the end of the decade.
- Revenue Guidance: Management indicated that they expect to achieve a $20 billion run rate in Q3, a quarter earlier than planned, and noted that the third quarter is running at the high end of their previous sales guidance. They anticipate sequential growth into Q4, with year-on-year growth rates in the high teens.
- Springboard Plan: While management did not raise the long-term targets of $30 billion by 2028 and $40 billion by 2030, they expressed confidence in achieving these goals sooner due to strong demand and strategic partnerships. They emphasized that deals like the Verizon agreement enhance their confidence in the Springboard plan.
- Optical Demand: Management reported strong demand in the optical segment, particularly in data centers and AI applications, stating that 'orders continue to pick up' and visibility into future demand remains robust. They expect this momentum to continue into the next several years.
- Solar Business Growth: Corning's solar segment is experiencing strong demand, with a 90% year-on-year growth reported in Q2. Management noted recent regulatory changes that positively impact pricing and indicated that they expect to reach corporate average profitability in the solar business by the end of 2027.
What were Corning Incorporated's September 9, 2026 results?
- Revenue: $20B (Expected run rate for Q3, a quarter earlier than planned, with high teens YoY growth.)
- EPS Growth: Faster than sales growth (Management indicated that EPS growth is expected to outpace sales growth due to improved margins.)
- Solar Sales Growth: 90% (Year-on-year growth reported in Q2.)
- Operating Margin: Above 20% (Management expects to maintain operating margins above this level.)
- Fiber Production Increase: 50% (Planned increase in fiber production capacity to meet demand.)
- Connectivity Capacity Increase: 10x (Significant planned increase in connectivity capacity.)
Corning's strong performance and strategic partnerships position it well for continued growth, particularly in the optical and solar segments. The recent Verizon deal and robust demand in AI and data centers are significant catalysts. Investors should monitor capacity expansions and the execution of the Springboard plan as key indicators of future performance.
Earnings Call Speaker Segments
Asiya Merchant
analystDay 2 of Citi's TMT Conference. Asiya Merchant here. I lead the I lead the tech hardware and tech supply chain research here at Citi. Great to have all of you here with us today. On the stage here with me is Corning's EVP and CFO; Ed Schelsinger. We also have members of Corning's management here in the audience. I'm going to kick it off. I'm going to turn it over to Ed he has some prepared remarks, and then we're going to go into Q&A. I'll leave some time for investors to ask questions as well. Towards the end, please do raise your hand so we can bring the mic to you. Ed?
Edward Schlesinger
executiveThanks, Asiya, and thank you all for attending. Thanks for having us today. I just want to make a couple of comments. First, I may make some forward-looking statements I suggest that you review our filings and our website for potential reasons why actual results may differ materially from anything that I say today. Secondly, I wanted to just note that we had a customer announcement yesterday with Verizon. Hopefully, you've seen that announcement. It is a multiyear, multibillion-dollar deal to help Verizon build out a long-haul network, a new long-haul network that will support both their broadband part of the business as well as data center interconnect. And for us, it's really a great relationship with Verizon. We've actually been a supplier to Verizon had a relationship with them for 30 years. And here we are today, helping them build out the AI data center interconnect network of the future. So I think that's great. It's one of the reasons why we like these long-term relationships, and I'm sure we'll talk a little bit about some others as well today. The other thing I'd mention is we have previously shared that the data center interconnect opportunity for us was about a $1 billion opportunity, $1 billion a year by the end of the decade. Well, clearly, with the extension of our Lumen agreement, an agreement we signed with Zayo and announced a while ago and this Verizon deal, we're going to get to that number much sooner than the end of the decade. And I think the opportunity is bigger than that, and we'll come back at some point. We'll talk a little bit about what that means. So I think that's good news. We also -- I want to mention, in the context of our long-term financial plan that we call springboard, we had shared with investors that we expected to hit a $20 billion run rate by the end of this year. $30 billion by the end of '28 and $40 billion by the end of 2030. And deals like this really underpin our success and our ability to deliver those numbers, they give us more confidence in our ability to do that. We're not going to upgrade the $30 billion or the $40 billion today, but we'll certainly come back and share our views on how those things are playing out over time. But we do expect to deliver the $20 billion a quarter early here in the third quarter. And if you take that math and you compare it to the guidance we gave back in July, it means we're at the high end or slightly better than the sales guidance that we gave back in July. So the third quarter is running really well. And we expect the fourth quarter to be bigger than the third quarter. So we expect sequential growth, and if you take the year-over-year growth rate that we've been seeing in the second quarter, in the third quarter, we're in the high teens, and we expect that to continue as we go into the fourth quarter and into next year. So a lot of momentum at Corning, and we're glad to be here today. So I'll turn it back over to Asiya.
Asiya Merchant
analystGreat. That was a great segue into the questions because the first one was, I mean, you guys are doing high teens like you said, year-on-year growth, EPS growing even faster than that. As you kind of think about the springboard plan that you sort of provided the 2030, '40 back in May, like how are you thinking about end markets? Maybe you could just dig in a little bit where demand has been stronger for you guys, it underpins better confidence in the springboard plan that you're talking about. So just help investors think about that. Where is demand much stronger, maybe demands may not a little bit stronger in some of those end markets?
Edward Schlesinger
executiveYes. So if I start with optical, clearly, the demand is very strong. We had an investor event in May, where we laid out our Springboard plan, and we felt really good about the optical space, the enterprise space, as we call it, our data center the AI data center space. And we continue to see really strong momentum there. Orders continue to pick up. We signed -- we're continuing to sign agreements, and we feel really good about visibility going out the next several years. So that's all strong, and I'm sure we'll spend some time talking about that as well. And when I think about a customer like Verizon, that moves into the carrier space in optical and demand is also really good in the carrier space for us as well. In the solar space, I think the market conditions continue to get better. The demand for solar energy is strong. There's also been continued regulatory announcements. There was a Section 232 ruling that helps pricing in the solar space. So that's another space where I think the market is really good. And we have work to do to build out our capacity continue to take advantage of that. But I think the market environment is very conducive for success for us there. In our Glass Innovations segment, we really have a number of markets. We have the display TV market, which remains solid, continued good performance. The panel makers continue to run at relatively high utilization rates. We continue to see screen size growth. So in the display space, we feel pretty good. I think you all know that in the handheld space or consumer electronics, the markets are actually down. We're expecting them to be down year-over-year, primarily because of the price and shortage of memory -- we don't really see a change in that from how we've been thinking about it, but we'll continue to outperform those markets as we sell content into the handheld space. So we'll sell more dollars per device, so we'll do better than the underlying market. We also supply the semiconductor market in our advanced optics business, and that actually is a pretty strong market, and I expect that to be a grower for us over the next several years. So I think our glass innovation business will grow despite maybe the handheld market not being that strong. Automotive remains muted. No change in our view there. Heavy duty, maybe slight recovery. We're starting to see that in North America, but we're not expecting a significant change there. Again, we'll outperform the market as we sell more content into the market with respect to emissions as well as glass into the auto space. So that's probably the view. So definitely, overall, on average, a little better but mixed certainly across the board.
Asiya Merchant
analystOkay. And then I know we'll jump into the DCI and optical in a bit here. But at the event back in May, you guys have the springboard plan 2030, '40, but then you also layer in kind of like a high confidence plan an internal plan just help investors understand like what needs to happen for that gap to narrow? I mean, clearly, '26 is entering very soon. But like when we look into the '28 and 2030, what needs to happen for that gap to sort of narrow between your high confidence plan and the internal plan?
Edward Schlesinger
executiveYes. I mean I think signing deals like we did with Verizon and have done with other customers and have others in the works, that certainly gives us more confidence that we can get to that the upper bound and maybe beyond those numbers that we shared. I think the largest variable, especially as you go out to the end of the decade is CPO or photonics what happens with adoption of those types of products. We are planning to build out a $10 billion business where today, we have no sales by the end of the decade, selling products into NPO and CPO applications, so inside of a server tray. And I think the timing of that and the adoption rate of that will have an impact on our ability to close that gap. I think the good news is -- we're starting to see a lot of activity. We're starting to build out our supply chain. And hopefully, next year, we'll start to see some sales there. We'll have a little bit of a better sense for how that plays out over this next several years.
Asiya Merchant
analystOkay. Great. And then I've been asking all the companies that are presenting here that I'm hosting about the AI demand. And clearly, it's a big driver for you guys, especially in your optical segment. You just talked about the deal with Verizon. Just as you think about it, it was a strong driver for you guys in 2Q as well. What gives you the confidence that this AI has durability to it. It's not just a short-term capacity push because everybody is obviously constrained for capacity, including fiber?
Edward Schlesinger
executiveYes. I think there are a lot of vectors or ways we try to triangulate around the certainty of demand. First, our orders are going up. So our customers are telling us they want to buy more to build out their data centers. That's a good data point, and it gives us good visibility into the next -- certainly the next 2- to 3-year period. Our customers are also signing up for long-term agreements. They're giving us cash in some cases, to build capacity and reserve that capacity. So that is also a good sign. I think -- if I think about it from a market perspective, token usage is going up quite significantly the companies that are generating revenue from AI, they're doing really well. So there seems to be adoption, and the opportunity continues -- the potential opportunity continues to increase. I think a lot of folks who predict the spending into the space are continuing to raise their targets for whether it's -- how many XPUs or accelerators will be deployed or how much data center capacity will be deployed, those numbers continue to go up. So I think that's also important for us. Now we're realistic and we want to risk against potential slowdown. So we do things to ensure that we're prepared for that, but we want to also be able to supply upside to the extent that it's bigger than what we have in our plan. So we're managing that as we add capacity, and we're trying to stay close to how we think the infrastructure gets built out.
Asiya Merchant
analystBefore we jump into enterprise AI, we can talk a little bit about DCI first because that is the major agreement that you guys signed yesterday. You talked a little bit about that $1 billion opportunity would be sooner -- just help understand investors understand the difference when we think about DCI versus traditional carrier fiber-to-the-home demand that is part of this Verizon deal, how should we think about the ratio between that -- what's more beneficial for Corning as you guys are deploying both on the carrier side, both on the broadband as well as on the DCI side.
Edward Schlesinger
executiveYes. So first for us, we have a lot of -- we are Corning as a technology company at its heart. We innovate, we introduce new products. We tend to lead in the industry or in the space in the market that we serve. So we have a very dense fiber cables. We introduced those inside the data center. We're selling those to Lumen for their DCI interconnect. So it allows them to have a lot more fibers packed into the same diameter cable. And that's one of the reasons why we think we're successful in the DCI space. Now if I think about Verizon, they're going to do both broadband and genAI, so they want a lot of fiber. So they want to do their deployment and get the maximum out of that. And I think that's one of the reasons why our innovations are successful and we're able to take that business. I don't know that I would say DCI or fiber to the home, one is necessarily more beneficial. We like to sell a solution. So a fiber-to-the-home solution is a good outcome for us in both Verizon and AT&T have talked a lot about passing more homes by the end of the decade. So we expect to continue to see growth in the broadband space that we like. If to the extent we can sell full connectorized solutions to someone like Verizon for fiber-to-the-home, that's a great outcome for Corning. And data center interconnect is really important because if we can connect data centers and allow the hyperscalers and others to continue to build that out, also really important for us. So I don't know that I would say one is necessarily better than.
Asiya Merchant
analystOkay. And then you have talked a lot about enterprise optical. Obviously, you've provided some interesting stats at your Investor Day, you could see that market growing 1.3x to 1.5x GPU growth, you talked about large clusters, bandwidth growth. Which one of those drivers do you see as the biggest -- most favorable development that's going on since maybe the Investor Day? Is it bandwidth clusters? Is it -- or sorry, bandwidth growth, clusters, scale-up optical? How are you thinking about the growth drivers there?
Edward Schlesinger
executiveYes. I think longer term, so certainly, let's say, from now to the end of the decade and beyond, scale up, photonics are going to be the largest driver, the growth driver. It adds to our TAM significantly. So if I think about what we sell today, your -- the TAM we will have in the future as optics begin to replace copper inside the data center, that TAM is a multiple of what we have today. So that's the largest driver. I would say what's driving our sales today, let's say, 2025, '26 into '27 is scale out of the network, larger data centers, more GPUs, those GPUs need to be connected to each other. So much more fiber is being sold. And as you get into the larger cluster size, which we expect to see, $130,000 is a good barometer, you add another layer to the network, so you add more fiber even just in the scale-out part of the network. So that is definitely happening, and that is driving our growth now, and we expect that to continue certainly in the short term. And I would expect scale up of the network to begin as you get into the end of next year into 28 through 2030. And then as I mentioned earlier, photonics is a huge driver, and we'll learn more quarter-over-quarter, and we'll be able to share our perspective. And you should certainly listen to what a lot of the large players, NVIDIA, Broadcom, et cetera, are saying when they talk about deploying their product sets.
Asiya Merchant
analystAnd I know Wendel often talks about, if I could sell more, we would buy more. And you guys have talked about increasing fiber capacity even connector capacity. I think you said connectivity capacity by 10x, fiber production by 50%. What are the time lines for these ramps to happen for these production to catch up to demand?
Edward Schlesinger
executiveYes. So we have been adding capacity, certainly, the last several quarters, maybe almost a year now, kind of quarter-over-quarter, we've been bringing on capacity. It's primarily been able in connectivity as Asiya mentioned, we're committed now to significantly increase our fiber capacity. We're doing that here in the U.S. We're the world's largest, lowest cost fiber factory is. So I think that actually sets us up really well to supply that $40 billion opportunity and beyond. The net fiber capacity will start to come online in not that distant future and certainly continue out over the next several years. We are not fiber constrained today. We expect to be, and that's why we're bringing on that capacity. It's tied to our customer agreements. We're also adding cable capacity and connectivity capacity. And as you mentioned, we're significantly increasing our connectivity capacity as we expect scale up to drive a lot of growth, and that's where we expect to really be constrained relative what our capacity is today. Another thing that I would mention is a lot of our long-term agreements and just in general, require us continue to do technology work and advance the types of connectivity that will be required. So if I think about moving inside of a switch tray or a server tray, you're going to need different connectors, you're going to need different optical components, and we're innovating to bring those things to market. We expect to be a leader in that. And I think that's part of our capacity add as you go out towards the end date.
Asiya Merchant
analystAnd when you think about the development of all these various productions and whether it's connectors, whether it's on the fiber side, are there things in your supply chain that need to catch up as well so that your -- the demand is fulfilled as you see it as you see your own supply coming online?
Edward Schlesinger
executiveYes. I think the biggest thing that investors should watch is the build-out of the CPO supply chain. I think that is the largest build out certainly in the passive optical space that needs to happen. Some of that is us, some of that is componentry that we may purchase. We may ultimately make ourselves. That sort of doesn't exist today, certainly the scale that is required does not exist. I think that is the largest bill. We're in the midst of doing that. I don't see anything that seems like a showstopper, but certainly, there's a lot of work that has to happen for that to occur to be able to hit that $10 billion run rate we talk about or to hit the levels of growth that you'll hear in video talk about things like that.
Asiya Merchant
analystNow some of your peers, whether it's Prismian, Sterlite, for example, they have also beefed up domestic fiber production capacity fiber and cable, I would say. So when you think about your own fiber and cable production coming online, what -- how do you think about the supply demand? How are you making sure Corning is managing that risk so we are not oversupplied by, let's say, fiber and cable?
Edward Schlesinger
executiveYes. So we're fully integrated. We're really the only fully integrated supplier. We make fiber, we make cable, we connectorize it. Most of our competitors either make only fiber or fiber and cable or they make connectivity and they purchase their fiber, right? So that's sort of the way the industry is set up. There are some Japanese competitors that are integrated, but they're much smaller or much lower scale than us. So for us, the primary thing is we plan to consume the fiber we make into connectivity solutions, which are tied to these long-term agreements. So I think we're in a good place. We're managing our capacity relative to what we expect our demand. I think it's okay that others are adding capacity into the system, but I don't think of their risk profile necessarily as the same as ours.
Asiya Merchant
analystOkay. And then when we talk about AI and build-outs of data centers and consuming cables or consuming connectors, there is a lot of lumpiness, broadly speaking, some of the on the server side, on the compute side, people will talk about customer-readiness and delays. Like how does Corning think about managing the build-outs of these large data centers, clearly, they tend to be working capital intense as well? I know you're very focused on free cash flow generation.
Edward Schlesinger
executiveYes. So a lot of the long-term agreements we signed have many tenants to them. One is a risk management tenant. We want our customers to have skin in the game. So oftentimes, they give us cash to pay for the capacity build out. They can earn that cash back over time by purchasing from us, which is a good outcome for both of us. We also typically have some technology sharing arrangement where we get a view of their technology road map and it allows us to see what they need in the future so we can determine how best to solve their problems. I think that is one way to do that. Another way is to sort of bring on the capacity in chunks or modularize a little bit of how we do that versus you're bringing on an entire factory at a time, and that also allows us to manage risk to some extent.
Asiya Merchant
analystOkay. A little bit about the hyperscaler agreements. You guys have publicly announced already a few. Again, when we think about concentration risk around these three agreements that you've announced, potentially some more that are coming, how do you think about that? You have these structured long-term agreements but there is concentration risk around very big players that are participating in this optical on the enterprise side.
Edward Schlesinger
executiveYes. We actually like to flip that a little bit the way we think about large customers. They've actually served [indiscernible]. We've built these sort of franchise businesses with customers in other industries and we're looking to do that in the optical space. I think Apple is a great example. BOE, which is the world's largest panel maker is a great example. Verizon, who we announced a deal with yesterday is another good example where you sign a large arrangement, you have this working relationship that goes beyond the supplier and customer relationship, you help them create a lot of value by solving their problems and allowing them to do the things they do. It also creates a lot of value for us, a lot of value for investors, and over a 30-year period, you have sort of this terminal-value relationship with a customer. We think of that as like a franchise business for us. So with the hyperscalers with NVIDIA, with Broadcom, we look to do the same thing. And so although, yes, you create a big customer set, if you do it across the industry, you're where you want to be. I don't think the nitration risk is necessarily a bad thing. I actually think good thing. Now that said, in the data center space, we're also selling to the neoclouds and Tier 2 hyperscalers, if you will. So we have a relatively diverse set of customers beyond the primary players that you all might think.
Asiya Merchant
analystPhotonics, Ed, you talked about it, it's a $10 billion opportunity through 2030 that you guys have talked about. You said there's timing around adoption of that. Just if you could click down 1 more level, like what specifically should investors be watching out for? And the $10 billion, any kind of drivers there that we should think about? How you came up with that TAM, if you could share a little bit more?
Edward Schlesinger
executiveYes. So I think the TAM is much larger -- the potential TAM is much larger than that over time. So what we tried to do was think about if a specific adoption level of NPO or CPO were to take place, significantly less than 100% in a window of time by the -- let's -- in our case, by the end of the decade, how big of an opportunity could that be? So we're thinking if the entire optical -- if the entire data center infrastructure went optical inside the box, that TAM is very significant, much larger than the $10 billion opportunity for us. And of course, time because we're putting out a plan in terms of time. I think what you should look at, first and foremost, are what are our customers talking about. And in this case, I think it's anyone who is selling an accelerator, so certainly in NVIDIA and Broadcom, but also custom ASICs, the hyperscalers themselves will deploy that. How are they talking about the deployment and architectures for their accelerators? And are they using some form of NPO or CPO to do that, I think that is a good indicator of the timing I think you're going to see an inflection at some point. I believe that inflection up happens in the next 4 or 5 years. Doesn't happen in 2027 necessarily. But once we start to see that, we'll learn a little bit more about how the adoption works, the cost and sort of how powerful that optical cycle is and in what time.
Asiya Merchant
analystAnd I know you guys are always always innovating. I think there were some announcements around GlassBridge. Just maybe for those who may not be aware of that, just how does that kind of factor into that adoption curve that you're talking about?
Edward Schlesinger
executiveYes. In this window that we are focused on are 2030, '40, our springboard plan I think traditional product sets are going to drive the growth in CPO. So polarizing fiber and FAUs and the types of optical components that exist but really aren't at scale and aren't fully integrated today. I think in the future, you're going to see new product sets, and those new product sets could be something like a GlassBridge or other products that we're working on that incorporate glass or other optical components or maybe even eliminate some of the optical components that exist today and better and make the network function better. And that is sort of what we do. We really think that is the best opportunity for us in this space. It's less about assembling components that exist although we do that well, and we will do that. It's about inventing the next generation that makes the network more efficient, reduces cost, makes it easier to install. All of those things are what we're focused on with a lot of the OEMs that I think of as more a 2030-plus time frame opportunity.
Asiya Merchant
analystApple, it's going to be making some announcements today. You guys have a 100% share of the Apple cover glass and Apple Watch cover glass as well. And I think a lot of that is now being produced at our Kentucky facility. I think you've talked about that as well here. What have some of the incremental benefits of that relationship? And how should we think about the fact that Apple is also trying to bring a lot of that production here domestically, how does that kind of factor into that 2030, '40 Springboard plan?
Edward Schlesinger
executiveYes. So certainly tune into Apple's announcements today. I think Apple is probably the best example I can think of of a franchise customer for Corning, where we've been able to continue to help them be successful which increases our TAM on a device. So dollars per device has continued to go up. So even though the smartphone market over the last decade has been relatively flat, low single-digit growth at best we've been able to grow much faster than that as we continue to add in content and innovate and help them make their devices better. I think we will continue to do that. The relationship we have. We actually just had the 1-year anniversary of the announcement we made in Kentucky, and that relationship allows us to continue to innovate with them in conjunction with their next generation of devices. So certainly tune in and see what they have to say. But I think it's a an important aspect of how we think about growing in our glass innovations segment with a customer like Apple, but also just other customers in that space. And even in the semiconductor space, where there's going to continue to be the need for glass or glass substrates into semiconductor test equipment or the semiconductor substrate space that allows us to continue to grow faster than the underlying [idiscernible].
Asiya Merchant
analystRight. Is that driving -- not just in smartphones, but like you mentioned, semiconductor equipment as well. Is that driving more towards domestic production relationships like Apple?
Edward Schlesinger
executiveI would say we have seen really good traction for manufacturing in the U.S. We're a U.S. manufacturer. We make a lot of our products here. We tend to want to be where our customers are and where their supply chains are. And so for fiber and cable, we make a lot of our product sets here. We supply a lot of U.S. customers for their U.S. build-outs with U.S. product. We're doing that in solar. We've done that in our glass innovations business with Apple. We're actually starting to see it a little bit in Life Sciences and in other parts of our business. And I think the retention station is really promoting incenting or disincenting however you want to look at it to try to drive U.S. manufacturing. So we continue to see that as a positive catalyst for us.
Asiya Merchant
analystYes. Great. Switching a little bit to profitability. You've talked about EPS growth being much faster than sales growth. I know at the Springboard, you talked about operating margin potential out there you didn't necessarily specify your target, but obviously, EPS growth growing faster than sales growth. So if you think about what operational strategies maybe you're putting in place that will enable that EPS growth to kind of outperform sales growth.
Edward Schlesinger
executiveYes. So if I go back to the beginning of our Springboard plan, we had an operating margin of around 16% you set a target for 20%. We delivered that target earlier than we thought we would. What really drove that was we filled capacity we had excess capacity. We introduced new innovations. We're introducing them at a higher price point. So we're improving our mix as we continue to shift from older generation products to new generation products, specifically in optical communications, but certainly in other places I think those strategies, both of those things will continue to increase our margins and will allow us to have earnings per share grow faster than sales. We have not yet set a new profitability target, but what we have said is that we expect to be above that 20% level, and we have continued over the last several quarters to be there. And I would expect us to continue to accrete up profitability as our sales grow and certainly for EPS to grow faster than sales. I think price is an important component of the way we improve our margins. And for us, the way we think about it is improving the margin on a new product. Some of that is pricing, it may not be apples-to-apples pricing, but it's certainly pricing or the value we're bringing to the board.
Asiya Merchant
analystOkay. And then solar, you are within solar. Solar sales are pretty strong. I mean, 90%, I think, year-on-year growth here in 2Q. You raised your solar opportunity as well, but you are still ramping certain on the factory side as well. And you talked a little bit about that. So what does it take for the solar business to reach like corporate average profitability? And what's sort of the time line to that?
Edward Schlesinger
executiveYes. So in solar, we're doing 3 things. We make polysilicon, which is the base material. We are turning that polysilicon into a wafer which then has a cell printed on there. And then we also are turning that cell into a module. So we're doing 3 out of the 4 steps to make a solar module. As I mentioned earlier, there's been recent legislation that helps to put a floor on the price per watt for a module, which is good. It sort of increases the market pricing. So that's actually a positive for us. It certainly will help our profitability. On the polysilicon side, we've got our capacity in place. We're optimizing it, but we're in pretty good shape. We're adding wafer capacity, getting that capacity up to the full potential, and we're adding module capacity getting that up to the full potential. Two things will happen when our sales will go up, we'll be able to make and sell more. And secondly, we'll be running efficiently. So we'll be able to get rid of the cost drag that we have that happens when you build a big infrastructure business. So we continue to improve quarter-over-quarter. We expect that to continue to be the case. I'd say by the end of 2027, we should be able to get to the profitability level that we expect in this business. And then we should be at or above that corporate average.
Asiya Merchant
analystOkay. I'm going to just turn around and see if investors have any questions, please do raise your hand. If not, I'm going to continue here. You've generated a lot of free cash flow. And I think, Ed, you've continued to say that free cash flow conversion, capital allocation is very important. High-teens ROIC is very important. Now that you're doing a lot of build with -- on the optical side, you're ramping solar, the Kentucky facility for the for the cover glass, I'm not sure where we are on that one, but just -- it's a pretty capital-intensive phase part of the Springboard, but yet you're talking about very, very strong free cash flow conversion. Just help us understand customer prepayments, how that is kind of helping you manage this risk on a capacity as you go into your capacity build to meet your springboard targets?
Edward Schlesinger
executiveYes. First, free cash flow is really important for us. We're also really proud of getting the ROIC into the upper teens. I'd like to get it to 20%. I think that is a possibility. I think if we can grow in the high teens and have an ROIC at that level, it's a huge value creation opportunity. And certainly, that converts to a lot of cash flow. And we expect our free cash flow to continue to grow maybe in line with our earnings growth or something along those lines. There will be quarter-to-quarter lumpiness. We might receive a customer deposit in one quarter and then we might spend capital in a different quarter. So you might see a little bit of lumpiness. But over a year, period of time or a multiyear period of time, we expect free cash flow to continue growth. We like the customer deposits, as I mentioned earlier, it gives us certainty about our investment. It gives us the ability to continue to sell to that customer. They're sort of tied to us and allows us to innovate. So I feel like despite adding capacity, we will become a little less capital intense in the nature of the capacity we're adding in optical connectivity space, for example, it's less capital dollars per sales dollar than in other parts of our business. So that's helpful. But also the customer deposits help sort of smooth out a little bit the free cash flow that we might otherwise generate. But again, cash flow going up year-over-year, that's how you should think about it.

analystWell, I'm going to thank Ed here. We're up on time. So thank you very much, Ed and Corning's management team and look forward to the Springboard update, the margin update.
