New York, Feb 26, 2026, 18:47 EST — After-hours
- Shares fell 6.3% in the regular session and slipped further after the bell.
- The stock’s pullback follows a fast rally and a fresh Citigroup price-target hike.
- Next catalysts include a dividend record date and investor conference appearances.
Corning Inc shares (NYSE: GLW) closed down 6.3% at $150.30 on Thursday and slipped another 1% to $148.73 in after-hours trading. The drop came a day after the stock ended at $160.43, up from $139.51 on Feb. 20. 1
The reversal matters now because investors have been leaning into Corning’s pitch that faster growth is back, helped by optical communications demand and a push into data-center buildouts. In late January, CEO Wendell Weeks told investors the company had a “highly profitable launch point for future growth” as it upgraded its Springboard sales plan and forecast stronger first-quarter results using its “core” metrics, a non-GAAP measure that strips out certain items. 2
Thursday’s slide also tracked a broader retreat in U.S. stocks, with technology shares among the laggards as investors digested a pullback in Nvidia and other AI-linked names. The mood turned choppier after two up sessions for the major indexes. 3
Corning opened at $158.36 and traded as low as $148.50 during the session, according to Investing.com data. Volume was about 16.3 million shares, roughly in line with the heavier trade seen during the stock’s recent surge. 4
Wednesday’s close at $160.43 was Corning’s highest on record, after the stock hit a 52-week high of $162.10 the same day, according to Macrotrends data. 5
Citigroup on Wednesday raised its price target on Corning to $170 from $120 and kept a Buy rating. The bank also opened what it called an “upside 30-day catalyst watch” on Corning and optical peer Lumentum ahead of the Optical Fiber Communication conference on March 17-19, describing the two companies as “pillars” in the AI optical networking ecosystem. 6
A filing on Thursday showed an affiliate filed a Form 144 for a proposed sale of 137,514 Corning shares. Form 144 is an SEC notice used for planned sales under Rule 144, and it does not mean a transaction has been completed. 7
The company is also heading into its next dividend record date on Friday. Corning’s board declared a quarterly dividend of $0.28 per share payable March 30 to shareholders of record on Feb. 27, the company said. 8
The stock’s recent run has been steep even before Wednesday’s sprint. Corning rose 4.4% on Tuesday to close at $151.59, according to MarketWatch, before pushing to new highs a day later. 9
But the fast climb leaves the shares prone to sharp givebacks if expectations run ahead of near-term demand or margins. After Corning’s latest earnings, William Kerwin, senior equity analyst at Morningstar, warned it was “time to temper the excitement” because much was “baked into the stock price already,” Reuters reported; the same report noted Corning’s fiber-optic products generate nearly 40% of revenue. 10
Investors get another check-in on Friday, Feb. 27, when Corning is scheduled for Susquehanna’s Fifteenth Annual Technology Conference, with one-on-one meetings listed with Investor Relations Vice President Ann Nicholson. 11
Another near-term marker comes March 3, when CFO Ed Schlesinger is due to present at Morgan Stanley’s Technology, Media & Telecom Conference in San Francisco, with a live webcast planned. 12
