    Executive summary

    Corning Q3 FY25 — Strong Springboard Execution and AI/Solar Growth

    Corning delivered another strong quarter, significantly advancing its Springboard plan with robust sales and accelerated EPS growth. The company is benefiting from secular trends in AI and solar, driving substantial expansion in Optical Communications and the new solar business. Management anticipates achieving its 20% operating margin target a full year early, underscoring improved profitability and a strong return profile for the business.

    Highlights

    5
    • Sales grew 14% year-over-year to $4.27 billion, demonstrating strong execution of the Springboard plan.

    • EPS grew 24% year-over-year to $0.67, outpacing sales growth and reflecting improved profitability.

    • Operating margin expanded 130 basis points to 19.6%, with the 20% target now expected a full year ahead of plan in Q4.

    • Optical Communications sales grew 33% year-over-year to $1.65 billion, driven by 58% growth in enterprise networks due to Gen AI.

    • Free cash flow reached $535 million, putting the company on track for another year of strong FCF growth.

    Concerns

    3
    • Operating expenses were $826 million, above the normalized run rate, primarily due to higher variable compensation expense including stock compensation.

    • Net income in Hemlock and Emerging Growth Businesses reflected ramp costs for new solar products, impacting profitability in the segment.

    • Heavy-duty diesel sales in North America were lower, partially offsetting growth in the Automotive segment.

    Risks & headwinds

    Temporary impact of solar ramp costsQ4 FY25

    Mitigation: Expected to be temporary; will subside as facility ramps to full capacity and sales increase, improving gross and operating margins.

    Lower heavy-duty diesel sales in North AmericaQ3 FY25

    partially offset growth

    Mitigation: Expected to bottom out and start to recover, providing a lift to the Automotive segment.

    Operating expenses above normalized run rateQ3 FY25

    $826 million

    Mitigation: Primarily due to higher variable compensation expense, including stock compensation, driven by significant stock price increase, which management frames as 'pay for performance'.

    What to watch in Q4 FY25

    4

    Solar wafer production ramp

    Q4 FY25
    Currentthousands of wafers a day
    Target>1 million wafers a day

    Why it matters

    Successful ramp of the new U.S. solar facility is crucial for achieving the $2.5 billion revenue target by 2028 and establishing Corning as a low-cost producer.

    In this quarter, we expect to move from producing thousands of wafers a day to more than 1 million a day. So needless to say, this is an exciting and stimulating time for us.

    Q&A highlights

    7

    Analyst noted that optical sales growth, while good, might be below expectations based on other optical players. Asked about timing effects between Q3 and Q4 or if this is the right run rate.

    Management highlighted significant growth in the data center business ($2B increase in annualized sales since 2023) and strong growth in carrier networks. They indicated that quarter-to-quarter timing can depend on specific customer plans and that demand for their products is very high, often exceeding current supply. They are in discussions with customers about derisking capacity investments.

    I think to maybe follow up after the call with Ann and let's make sure that sort of how you're thinking about models and what's happening in a quarter -- any given quarter is one place for us to start, so we make sure we don't talk past each other. What I'd add to Ed is sort of every time we're in a conversation with our customers, they want more from us. And things are quite tight right now.

    Detailed Narrative

    01

    Springboard Plan Exceeding Expectations

    Corning's Springboard plan, launched in Q4 2023, has been a tremendous success, with the company significantly outperforming its initial targets. Since launch, sales have grown 31%, operating margin expanded by 330 basis points, and EPS increased 72%, more than double the rate of sales growth. The company has added $4 billion in incremental annualized sales and expects to achieve its 20% operating margin target in Q4 2025, a full year ahead of schedule. This enhanced profitability is expected to translate into attractive returns as sales continue to grow.

    02

    AI-Driven Growth in Optical Communications

    The Optical Communications segment is experiencing robust growth, primarily fueled by Gen AI. Sales grew 33% year-over-year, with enterprise networks, which includes inside-the-data-center sales, surging 58%. The enterprise business's annualized run rate has increased by $2 billion since 2023, reaching $3.3 billion, largely due to the scale-out of Gen AI networks. Corning is also pursuing the 'scale-up' opportunity, where fiber connections replace copper as AI nodes stretch across multiple server racks, potentially tripling the size of the existing enterprise business. Innovations like high-density Gen AI fiber and cable for data center interconnect (DCI) are also scaling rapidly, expected to become a $1 billion business by the end of the decade.

    03

    Strategic Expansion in Solar Business

    Corning is making significant strides in its solar business, aiming to build it into a $2.5 billion revenue stream by 2028. The company has successfully built the largest solar ingot and wafer facility in the United States, co-located with its polysilicon manufacturing in Hemlock, Michigan. This facility, equivalent in scale to the Salesforce Tower, is ramping up production from thousands to over 1 million wafers per day in Q4. Corning has committed customers for over 80% of its capacity for the next five years, with the goal of establishing itself as a global low-cost producer of domestically made solar wafers.

    04

    Mobile Consumer Electronics and Apple Partnership

    A recent announcement with Apple commits $2.5 billion to produce 100% of iPhone and Apple Watch cover glass in the U.S. at Corning's Harrodsburg, Kentucky facility. This plant will become the world's largest and most advanced smartphone production line, and a new Apple-Corning Innovation Center will deepen co-innovation. This partnership is expected to create a significantly larger, longer-term growth driver in mobile consumer electronics, with future profitability driven by the adoption of new glass innovations.

    05

    Display and Specialty Materials Performance

    The Display segment is performing well, with Q3 sales of $939 million and net income of $250 million, both slightly up due to stronger panel maker utilization. The company expects full-year 2025 net income to be at the high end of its $900 million to $950 million range, with a net income margin of at least 25%. Specialty Materials delivered a strong quarter with sales up 13% year-over-year to $621 million and net income up 57%, driven by premium glass innovations for flagship product launches.

    06

    Capital Allocation and Shareholder Returns

    Corning prioritizes investing in organic growth opportunities that drive significant returns, primarily through innovation. The company maintains a strong balance sheet with one of the longest debt tenors in the S&P 500 (average 21 years). It expects to continue its strong track record of returning excess cash to shareholders, with share buybacks being the primary vehicle going forward. Corning has repurchased 800 million shares over the last decade, reducing outstanding shares by nearly 50%.
