Corning maintains BUY; optical and AI remain core drivers, but target price cut to $200

Overview

This report focuses on a reassessment of Corning Inc.'s optical, AI, Solar, and margin trends after its 2Q results. BofA reiterates its BUY rating, believing that although 3Q revenue guidance is slightly below consensus expectations, some non-enterprise and Solar segment growth is slower, and there is a lack of more hyperscaler detail, Enterprise Optical remains strong, driven by data center and Gen AI demand, and Corning still has multi-year growth characteristics.

Core views

The core view is that Corning's investment thesis is unchanged: Optical revenue is structurally rising, data center demand driven by Gen AI supports continued growth in the enterprise optical business, and new MAPs bring incremental operating profit. At the same time, the report acknowledges that the market now demands greater upside surprise in performance to justify Corning's high valuation, so it lowers the target multiple from the previous 37x to 31x.

Analysis framework

The report uses a combination of earnings review, segment driver analysis, management guidance comparison, valuation multiple methodology, and earnings forecast revisions. It focuses on comparing 2Q enterprise optical, Solar, margins, and 3Q revenue/EPS guidance, and derives the price target using 2028E EPS and the target P/E multiple.

Methodology notes

• Valuation methodsP/E multiple valuation

  The target price is based on 2028E EPS and the target P/E multiple

  The $200 target price is based on 31x 2028E EPS of $6.46; previously it was $243, based on 37x 2028E EPS of $6.50. The multiple reduction reflects broader concerns about the sustainability of data center construction.

• Fundamental QualityiQmethod SM

• GLW.US

  Direct coverage target

  Strengths

  Enterprise Optical is driven by Gen AI and data center demand, Solar growth is strong, operating margin improved both year over year and quarter over quarter, and the company has catalysts including Gorilla Glass, Fiber-to-the-Home, and capital return plans.

  Weaknesses

  3Q revenue guidance is slightly below market expectations, Carrier revenue is soft, growth in some non-Enterprise and Solar segments is slower, and valuation is already significantly above the historical median.

  Comparison

  The report notes that GLW's recent valuation exceeded 60x C26E, well above the 5-year median of 22x; the 31x target multiple also remains above the historical range of 10x to 24x and the 15x median.

  Risks

  Sustainability of data center construction, delivery against 3Q guidance, rising capital expenditures, LCD glass supply-demand imbalance, slowing TV sales, and declining customer utilization.

Impact & implications

The report's impact on GLW is somewhat positive: the buy rating is maintained and the target price still implies substantial upside relative to the current price, indicating that BofA remains optimistic about the optical demand cycle driven by AI and data centers. However, the target price cut from $243 to $200 also signals that under a high valuation, the market will pay closer attention to 3Q guidance, rising capital expenditures, and the sustainability of data center construction.

Risks

• 3Q revenue guidance is slightly below consensus expectations, which may weaken market confidence in near-term upside surprise growth.
• The sustainability of data center construction is debated, so the target P/E multiple has been lowered.
• Capital expenditures in 2H26 are rising to $2.0bn, above the previous $1.7bn, which may pressure free cash flow or return expectations.
• Carrier revenue was soft in 2Q, reflecting the impact of pull-forward demand in 1Q.
• Enterprise Optical growth is increasingly dependent on long-term agreements, and if pricing rises faster, upside elasticity may be limited.
• The timing of Scale Up and CPO adoption remains uncertain.
• Unexpected slowing TV sales, glass supply-demand imbalance, declining customer utilization, and higher-than-expected capital expenditures all represent downside risks.

What to watch

• Whether 3Q revenue falls within the guidance range of USD 4.9bn to USD 5.0bn, and whether EPS reaches the range of USD 0.85 to USD 0.89.
• Whether Enterprise Optical continues sequential growth after a strong 2Q, and whether Gen AI-related demand continues to exceed capacity.
• Whether the adoption timeline for Scale Up and CPO becomes clearer.
• Whether Solar wafer transition pressure subsides and brings sequential growth and margin leverage.
• The execution pace of the $2.0bn capital expenditure in 2H26 and its impact on free cash flow.
• Whether the market continues to assign GLW a valuation multiple above its historical range.
