Ed Schlesinger
Executive Vice President and Chief Financial Officer at Corning
Thank you, Wendell. Good morning, everyone. We're off to a great start. We believe our second-quarter results are a strong proof point of both the sales and the incremental profit and cash flow opportunity in our Springboard plan. So before I dive into the results, I'd like to share some of the major growth drivers we see across our market-access platforms. Wendell shared with you our internal non-risk-adjusted plan, which is $8 billion in incremental sales by the end of 2028, and $5 billion by the end of 2026. I'm going to share some of the cyclical and secular drivers of this growth while focusing in on the three-year window. Let's start with Optical Communications.
The Gen AI opportunity Wendell spoke about, adds a significant amount of growth. We expect our Enterprise business to grow at a 25% compound annual growth rate from 2023 to 2027, driven by the adoption of our connectivity solutions for generative AI, and this is already underway. We delivered record sales in Enterprise in the second quarter, which grew more than 40% year-over-year. In our Carrier business, customers are reaching the end of their inventory drawdowns and beginning to order closer to their current deployment levels. Additionally, government efforts to bring highspeed Internet to rural communities through the broadband equity, access, and deployment program will contribute to growth beginning in 2025 and add significant sales over the next several years.
In Display, we're not counting on TV unit growth. Instead, we expect to capitalize on the trend of larger screens, with about an inch of screen size growth per year to add low to mid-single-digit volume growth. Additionally, as we've previously explained, we're currently undertaking currency-based price adjustments to maintain appropriate returns in our Display business. In automotive, we have a triple-digit automotive glass business today, and we expect sales in that business to almost triple by 2026. Recently announced U.S. EPA regulations will require the adoption of GPFs in the U.S., starting with model year 2027. This adoption offers hundreds of millions of dollars of growth for us in the U.S. alone, even in the face of BEV adoption. We expect sales to start in 2026. And finally, we expect to build an entirely new map as we leverage the Inflation Reduction Act to support the buildout of a U.S. solar supply chain.
These are just some of the growth drivers in our $5 billion opportunity. As Wendell shared, we probabilistically adjusted this opportunity to the $3 billion high-confidence Springboard plan we've been sharing with you since the third quarter of 2023. We expect to have strong incremental profit and cash flow as we capture the growth, and we're starting from a strong operating base. Our productivity ratios are at best demonstrated levels, and we've raised price to more appropriately share inflation with our customers. Our improvement in gross margin is a great proof point. In the second quarter of 2024, gross margin was 37.9%, up 430 basis points from 33.6% in the fourth quarter of 2022 on the same level of sales. With that, let me share some highlights from our second-quarter results.
Sales grew 11% sequentially, reaching $3.6 billion in the quarter, returning us to year-over-year growth. The outperformance versus our April guidance of $3.4 billion was primarily driven by the strong adoption of our new optical connectivity products for Gen AI. EPS grew 24% sequentially, more than twice as fast as sales, coming in at $0.47, also above our April guidance range. Gross margin improved sequentially and year-over-year by 110 basis points and 170 basis points respectively. Operating margin expanded 190 basis points versus the first quarter, and we generated strong free cash flow of $353 million. In Optical -- Next, let me turn to our segment results.
In Optical Communications, sales for the second quarter were $1.1 billion, up 20% sequentially, reflecting a return to growth for the segment. Year-over-year, sales increased 4%. Enterprise network sales were up 42%, driven by AI-related connectivity solutions. Carrier sales were actually down 10%, as customers continued to draw down their inventory. Encouragingly -- encouragingly though, carrier network sales grew sequentially, as customers began to order closer to their current deployment levels. We delivered strong incremental profit in Optical, with net income for the quarter at $143 million, up 43% sequentially on the 20% sales growth.
Moving to Display Technologies, second-quarter sales were $1 billion, up 16% sequentially, as panel makers ran at higher utilization rates in the second quarter to support mid-year promotions. Glass price was consistent with the first quarter. Net income was $258 million, up 28% sequentially. Year-over-year, sales were up 9% and net income was up 24%, driven by higher volume and price. Now, let me spend a minute on our approach to Display price going forward. As we've said before, we plan to make currency-based price adjustments to maintain appropriate returns in our Display business. We're in the midst of doing just that, and we will update you on our progress at an appropriate time.
With respect to the yen, we have hedges in place for 2025 and beyond. They're not at the 2024 core rate of 107, but they're much better than the current spot rate. We expect the combination of our currency-based price adjustments and our hedges to deliver an appropriate level of profitability for the display business. For your modeling purposes, you can think about appropriate profitability as being the average of the last five years of net income margin from our segment reports. Turning to Specialty Materials, sales in the second quarter were $501 million, up 18% year-over-year, driven by continued strong demand for premium glasses for mobile devices and semiconductor-related products. Net income was $63 million, up 91% year-over-year, reflecting volumes and manufacturing improvements.
In Environmental Technologies, second-quarter sales were $431 million, down 6% year-over-year, reflecting the impact of the Class 8 truck downcycle in North America as anticipated. Net income was $97 million, down 9% year-over-year on decreased volume. We expect the heavy-duty market weakness to continue in the second half of this year, and sales in Environmental to be down sequentially in the third quarter. In Life Sciences, sales in the second quarter were $249 million, up 8% year-over-year. Net income was $17 million, up 55% year-over-year. Turning to Hemlock and Emerging Growth Businesses, sales in the quarter were $296 million, down 21% year-over-year, primarily reflecting lower pricing for solar-grade polysilicon.
Now let me turn to our outlook. For the third quarter, we expect sales to grow to approximately $3.7 billion, driven primarily by our Optical Communications business, including the continued adoption of our new optical connectivity solutions for Gen AI products, which we expect will more than offset the expected slowdown in the US Class 8 truck market. We expect EPS in the range of $0.50 to $0.54, with EPS growing three times the rate of sales. As pre -- as we previously shared, our sales are running well ahead of our Springboard plan, and our incrementals are strong. In fact, if you compare our projected Q3 sales and EPS guide to Q4 2023, which is our Springboard base, sales are up approximately 13% and EPS is up approximately 33%. Additionally, in Q3, we anticipate another quarter of strong free cash flow.
As it relates to cash, our capital allocation priorities remain the same. We prioritize investing for organic growth opportunities. We believe this creates the most value for our shareholders over the long-term. As we've shared today, in the mid-term, we have the technical capabilities and capacity in place to add more than $3 billion in annualized sales with minimal cash investment, and you can see that reflected in our capex expectations for 2024 of $1.2 billion. We also seek to maintain a strong and efficient balance sheet. We're in great shape. We have one of the longest debt tenors in the S&P 500. Our current average debt maturity is about 23 years, with about only $1 billion in debt coming due over the next five years, and we have no significant debt coming due in any given year. And finally, we expect to continue our strong track record of returning excess cash to shareholders.
Since 2013, we bought back half of our outstanding shares or almost 800 million shares. This generated about $15 billion of value for our shareholders. Because of our growing confidence in Springboard, we started to buy back shares in the second quarter, and we expect to continue share buybacks in the third quarter. In summary, we're off to a great start on our Springboard plan. We're well on track to deliver on our $3 billion-plus sales opportunity. Our second-quarter results and our third-quarter guidance are strong proof points of the incremental profit and cash flow we expect to deliver as we capture the sales growth. I look forward to sharing more in the coming months as we make progress on our Springboard plan and continue to create value for shareholders.
With that, I'll turn it back to Ann.
