Corning Inc. (GLW) shares fell more than 4% on Tuesday, extending a sharp pullback as investors continued to sell artificial intelligence-related stocks despite analysts maintaining a positive long-term outlook on the glass and optical networking company.

The stock dropped 5.4% to $184.33 and was on track for its fifth consecutive daily decline.

Over the current four-day losing streak, Corning shares have fallen about 24%, erasing approximately $52.4 billion in market value as semiconductor and AI infrastructure stocks came under broad selling pressure.

Despite the recent weakness, the stock remains up 105% in 2026 and has gained 256% over the past 12 months, reflecting investor optimism surrounding AI-driven demand for optical networking products.

Analysts raise price targets despite recent selloff

Oppenheimer analyst Martin Yang raised his price target on Corning to $230 from $210 while maintaining an Outperform rating.

“We view the AI-infrastructure unwind as an attractive entry point into GLW’s attractive long-term growth story,” Yang wrote.

Yang said Corning remains well positioned to benefit from near- and medium-term growth drivers as customers continue increasing capital spending on optical fiber infrastructure to support generative AI applications.

Bank of America also maintained a positive outlook on the company. Analysts led by Wamsi Mohan raised their price target to $243 from $223 and reiterated a Buy rating.

“We expect the quarter to reinforce that optical demand remains firm,” Mohan wrote.

According to the brokerage, investors are focused on whether Corning’s optical networking business can sustain growth beyond the near term as the company prepares to report second-quarter earnings.

UBS also reaffirmed its Buy rating and increased confidence in the company’s long-term growth outlook, setting a $228 price target.

AI infrastructure remains central to growth strategy

Corning has increasingly been viewed as a beneficiary of expanding AI infrastructure investment because of its products for optical networking, telecommunications and semiconductor applications.

The company manufactures glass used in notebook computers, desktop monitors and televisions, while also supplying optical materials and networking products used across data centers.

Corning has promoted its Corning GlassWorks AI Solutions platform as a comprehensive portfolio covering optical connections throughout AI infrastructure, from data centers to chips and long-distance network links.

Several major technology companies have recently expanded partnerships with Corning.

In June, the company announced a multibillion-dollar agreement with Amazon to manufacture optical fiber for data centers. Earlier this year, Nvidia committed an investment worth up to $3.2 billion to expand Corning’s optical networking manufacturing capacity in Texas and North Carolina.

Corning also secured a $6 billion agreement in January to supply Meta Platforms with cabling, optical fiber and connectivity products for data centers.

Investor day boosts long-term outlook

UBS said Corning’s recent investor day strengthened confidence in the company’s long-term financial targets.

The company increased its 2028 sales forecast by approximately 25% to nearly $30 billion and outlined a framework to reach $40 billion in annual sales by 2030.

UBS noted that the updated 2028 outlook was roughly 10% above previous expectations.

The brokerage raised its 2028 adjusted earnings per share estimate by 15% to $6.70 and introduced a 2030 EPS estimate of about $9.80.

The analyst cited stronger confidence in scale-out fiber demand, with Corning expecting fiber growth of 1.3 to 1.5 times the rate of GPU and ASIC growth.

UBS also highlighted the company’s expanding Photonics business, which Corning expects to generate approximately $10 billion in incremental sales by 2030, supported by long-term customer agreements and Nvidia’s previously announced investment.
