Edward A. Schlesinger
Executive Vice President & Chief Financial Officer at Corning
Thank you, Wendell, and good morning, everyone. As you just heard, we had another outstanding quarter and completed a strong first year of our springboard plan. Cyclical and secular trends are driving demand for our products. We have the capacity and technical capabilities in-place to add more than $3 billion in annualized sales by the end of 2026 and the cost and capital are already reflected in our financials. So this means that as we grow, we expect to grow profit significantly faster than sales. And that's exactly what you saw in the 4th-quarter. Sales grew 18% year-over-year to $3.9 billion and EPS grew 46% to $0.57, more than two times the rate of sales.
Operating margin expanded 220 basis-points to 18.5%, marking strong progress on the target we've shared to achieve 20% operating margin by the end of 2026. Overall, it was a terrific quarter and we expect our momentum to continue in 2025. In the first-quarter, we expect sales to grow 10% year-over-year to approximately $3.6 billion with core EPS growing approximately 30% to a range of $0.48 to $0.52. Based on our strong performance, we continue to track ahead of our springboard plan. So this morning, I want to share more details and perspective on our quarter and full-year results. For the full-year, we grew sales 7% to $14.5 billion. At the same time, EPS grew 15% to $1.96. Gross margin expanded 190 basis-points to 38.2% and operating margin expanded a full percentage point to 17.5%. We increased free-cash flow by $373 million versus the prior year to $1.25 billion.
Moving to the segments. In Optical Communications, 4th-quarter sales were $1.37 billion, up 51% year-over-year. Full-year sales grew 16% to $4.66 billion. In our enterprise business, sales were $686 million for the quarter, up 93% year-over-year, driven by the continued strong adoption of our new Gen AI products. This marks another record quarter of growth in this business. And for the full-year, enterprise grew 49% to $2 billion. We also grew year-over-year in our carrier business in the 4th-quarter as customers continued to buy closer to their rates of deployment. Net income for the full-year and 4th-quarter reflected strong incremental profit on higher-volume. For the 4th-quarter, net income for the Optical Communications segment grew 120 -- 120% year-over-year to $194 million. And for the full-year, net income grew 28% to $612 million. Overall, we expect our unique capabilities in optical communications to drive continued growth in 2025 and beyond.
In Carrier, we expect deployments to increase in 2025 as indicated by carrier customer conversations and public announcements. We also expect growing demand for our connectivity products for Gen AI, and we're just beginning to ship our new data center interconnect products to Lumen in the first-quarter.
Moving to Display Technologies, 4th-quarter sales were $971 million, up 12% year-over-year. Net income was $262 million. Full-year sales grew 10% to $3.87 billion. Net income was up 19%. The retail and glass market grew year-over-year as measured in square feet, driven by larger average screen size. Late in the quarter, panel makers increased their utilization rates as set makers upped their orders driven by government stimulus in China. We expect panel makers to continue at these utilization rates in the first-quarter of 2025.
As we shared with you in September and on our 3rd-quarter earnings call, we raised glass prices to deliver consistent profitability in the segment. We've successfully implemented double-digit price increases in the second-half of 2024 to ensure we can maintain stable US dollar net income in a weaker yen environment. We continue to expect to deliver net income of $900 million to $950 million in 2025 and net income margin of 25%, consistent with the last five years.
Turning to Specialty Materials, in the 4th-quarter, sales were $515 million, up 9% year-over-year and down 6% sequentially. Full-year sales grew 8% to $2 billion as we advanced our more corning content strategy in both Gorilla and advanced optics. Net income grew 40% year-over-year in the 4th-quarter to $81 million and was up 29% for the full-year to $260 million, reflecting strong incrementals on higher volumes as well as strong demand for our premium glass innovations.
In Environmental Technologies, our 4th-quarter sales were $397 million, down 7% year-over-year, driven by weaker light-duty and heavy-duty markets in Europe. Full-year sales were down 6% year-over-year as we continued to experience weaker global heavy-duty markets, particularly in Europe. Net income of $81 million for Q4 was down 17% year-over-year, reflecting lower-volume. Net income for the full-year was $358 million, down 7% on lower sales. In 2025, industry analysts expect the global light-duty market to remain flat and for the heavy-duty market to be down slightly, primarily in North-America.
In Life Sciences, 4th-quarter sales were $250 million, up 3% year-over-year and net income grew 6% year-over-year. Full-year sales were $979 million, up 2% as the market stabilized throughout the year. Net income grew 26%, significantly faster than sales. And finally, in Hemlock and Emerging growth businesses, 4th-quarter sales were $373 million, up 5% year-over-year. Full-year sales were $1.28 billion.
As you can see, we're making strong progress on Springboard. And as we enter 2025, we expect our momentum to continue. In the first-quarter, we expect sales to grow 10% year-over-year to approximately $3.6 billion with core EPS growing approximately 30% to a range of $0.48 to $0.52. Additionally, we have hedged our yen exposure for 2025 and 2026. We also have hedges in-place beyond 2026.
In 2025, we will be resetting our yen core rate to JPY120 to the dollar, consistent with our hedge rate. We have reflected the JPY120 core rate in our Q1 guidance. We do not plan to recast our 2024 financials because we expect to maintain the same profitability in display at the new core rate. And as I said earlier, in display, we expect to deliver net income of $900 million to $950 million in 2025 and net income margin of 25%, consistent with the last five years.
Now, I'd like to spend a minute on capital allocation. I've told you that we have the capacity and technical capabilities in-place to add more than $3 billion in annualized sales by the end of 2026. So we expect to deliver strong incremental profit and cash-flow as we capture the sales growth opportunity outlined in our Springboard plan. One proof point from the first year of the plan is that we grew free-cash flow by 42% in 2024 to $1.25 billion. And as our execution of Springboard continues, we expect to generate significant cash-in 2025.
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. In 2025, we expect our capital expenditures to be approximately $1.3 billion. We also seek to maintain a strong and efficient balance sheet. We're in great shape here. We have one of the longest debt tenors in the S&P 500. Our current average debt maturity is about 23 years with only about $1.2 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, we started to buy-back shares in the second-quarter and we have continued to do so throughout 2024.
So as I wrap-up today, I'd like to reiterate that we had an outstanding 4th-quarter that capped off a strong first year of springboard. Compared with Q4 2023, our starting point for Springboard, sales grew 18% year-over-year to $3.9 billion. EPS grew 46% to $0.57 and operating margin expanded 220 basis-points to 18.5%, marking strong progress on the target we've shared to achieve 20% operating margin by the end of 2026. Looking ahead, we expect 10% year-over-year sales growth in the first-quarter with EPS growing about three times faster. And we expect to sustain our momentum throughout 2025. In total, we're tracking ahead of our high confidence plan to add more than $3 billion in annualized sales by the end of 2026. And we look-forward to our March investor event when we plan to provide you with an update to our high confidence springboard plan. Thank you, everyone.
And with that, I'll turn it back over to Ann.
