New York, March 3, 2026, 19:00 EST — After-hours
- Corning dropped roughly 6.6% after hours Tuesday, giving back some of the gains from its surge the previous day.
- Gorilla Glass Ceramic 3 landed on Motorola devices, while the glassmaker gave investors an update at the Morgan Stanley conference.
- Mobile World Congress news is on the radar for traders, along with Friday’s U.S. jobs numbers—both seen as the next signals to watch.
Shares of Corning Incorporated slid roughly 6.6% to $147.57 in after-hours trading Tuesday. The stock swung between $141.45 and $153.64 during a volatile session.
Corning’s decline is catching attention, given its exposure to two volatile corners of the market: premium smartphone demand and the ongoing push to expand fiber and cable networks within data centers.
Both popped up in headlines this week. Depending on what investors believe is already factored in, that sort of attention can either push a stock higher or knock it back.
Corning on Monday rolled out its new Gorilla Glass Ceramic 3, announcing that Motorola will feature the material on an upcoming razr foldable. “We engineer our materials with longevity in mind, not just initial performance,” said Lori Hamilton, division vice president and business technology director at Corning Gorilla Glass. Leo Liu, Motorola’s product-development vice president, called the cover upgrade a boost to “the durability of our design.” The device is scheduled to debut at Mobile World Congress, March 2-5.

Speaking at Morgan Stanley’s technology, media and telecom event on Tuesday, Corning CFO Edward Schlesinger told the audience the company is “starting to get close” to doubling in size over a five-year stretch, flagging a $24 billion revenue run-rate goal for 2028. Optical communications is where the bulk of capital is heading, Schlesinger said, but he stressed the risks. “You don’t wanna build a factory” without clear demand, he warned. Investing.com Australia
On Monday, Corning’s optical communications division spotlighted its network equipment business, touting the iF Design Award for its Evolv Openable Terminal. “The award validates our ongoing commitment,” said Kevin Parker, senior vice president and general manager for optical connectivity solutions, pointing to new fiber offerings targeting broadband expansion.

Data centers are becoming an even larger part of the optical story. Back in January, Meta Platforms struck a deal with Corning that could reach $6 billion over several years, aimed at supplying fiber-optic cables for Meta’s AI-driven data centers, both companies confirmed. Reuters
The stock surged into this week. On Monday, shares climbed roughly 5%, closing just below $158. That put the price within 3% of its 52-week high, with trading volume topping the 50-day average, MarketWatch data showed. MarketWatch
U.S. stocks took a hit Tuesday, dragging Wall Street’s major indexes down hard. The market faced renewed concerns about inflation after energy prices jumped—blame rising tensions in the Middle East, according to a Reuters report. Reuters
Yet the near-term outlook for Corning is anything but straightforward. If consumers hold off on phone upgrades, that’s a direct hit to the specialty materials side. A slowdown from hyperscalers would filter into optical order volumes. Capacity spending can be a double-edged sword here as well.
Investors are eyeing Mobile World Congress for potential new device reveals. They’re also looking to see if Corning can land additional long-term data-center supply contracts—without sacrificing margin.
The broader market faces its next big read on Friday, when the U.S. February jobs report drops March 6 at 8:30 a.m. ET—a data point known to jolt rate bets and stir risk sentiment in tech-related stocks. bls.gov
