Corning (GLW) Gets Jefferies Buy and $134 Target on AI Fiber Demand

Corning just got a fresh vote of confidence at a moment when it badly needed one. On Wednesday, Jefferies started coverage of the glassmaker with a Buy rating and a $134 price target.

The shares jumped more than 10% at the peak, according to CNBC's running coverage of the day's biggest movers. That target works out to roughly 19% upside from Tuesday's close.

Context matters here. Corning (GLW) has fallen about 40% over the past six months, and the 52-week range runs from a low of $77.39 to a high of $271.78. So Wednesday's pop was a bounce inside a rough stretch, not a breakout.

Jefferies analyst Dushyant Ailani argues the market has been slow to appreciate how much the business has changed. In his note, Corning has "undergone a significant re-rating" from a glassmaker tied to consumer electronics and displays into an AI optical infrastructure play.

The core of the thesis is supply. As Yahoo Finance reported from the note, Jefferies points to multi-year contracts with hyperscalers and telecom carriers as the backbone of Corning's growth outlook.

Seeking Alpha's summary of the note says the firm expects an optical-fiber shortfall of around 30% in 2026 to persist. Tight supply, in plain English, gives Corning pricing power and a clearer view of future orders.

Jefferies expects the Optical business to start scaling in 2028, as fiber moves from simply linking machines to being built into data-center equipment itself. Progress in the Enterprise and Carrier segments should help the company move toward its 2030 targets.

Not everything gets the same enthusiasm. The firm is more cautious on Photonics, which it expects to ramp up more gradually, and says next-generation pluggable optics and co-packaged optics are the catalysts to watch.

Jefferies' $134 price target implies about 19% upside, even after a rally of as much as 10% on Wednesday and a slide of roughly 40% over six months.

Here's how Corning has been doing on the numbers. For the quarter reported October 27, MarketBeat's rundown of the Jefferies call shows earnings of $0.91 a share against $0.88 expected, on $5.08 billion in revenue, up 18.9% from a year earlier.

The stock's problem isn't the quarter. It's the multiple and the mood around AI spending. The stock trades at about 45 times earnings, and the whole AI-infrastructure group has been whipsawed by data center worries and rate fears.

The Street isn't uniformly bullish either. Bernstein trimmed its target to $120 from $140 with a market-perform rating earlier this week, and Morgan Stanley cut to $155 from $165 at equal weight in late October.

Still, the consensus leans positive. MarketBeat puts the average target near $172 with a Moderate Buy rating, which means Jefferies' $134 is actually below the average. The new call is more about the direction of travel than an outlier price.

The bull case also has a hard-nosed partner behind it. Back in May, Nvidia agreed to buy 3 million Corning shares and take warrants for up to 15 million more at $180 apiece, as 24/7 Wall St. reported. That ties a major AI customer's upside directly to Corning's execution.

Now the risks. Valuation is the big one, and GuruFocus flags Corning as significantly overvalued on its own fair-value model. You can quibble with any model, but it's a reminder that a lot of good news is already priced in.

Insiders haven't helped the narrative. GuruFocus notes no insider purchases over the past 12 months and about $98 million in insider selling. And Jefferies itself says the Photonics ramp could take time, so patience is part of the deal.

There's also the macro overhang. A hotter-than-expected CPI report has traders pricing a December rate hike, and higher rates tend to hit richly valued growth names hardest. Any fresh wobble in AI capex plans would hit Corning too.

So what do you do with this? If you already own Corning, Wednesday's move gives you no reason to panic, but it isn't a reason to chase either. The sensible watchlist item is the $120 area where Bernstein sits, versus Jefferies' $134 and the $155 Morgan Stanley level.

If you're thinking about starting a position, consider building it in pieces rather than all at once. A stock that's 40% off its recent run and 19% below one analyst's target can still swing wildly on a single rate headline.

Keep an eye on three things: any update on the fiber shortage, news on hyperscaler contracts, and early signs of co-packaged optics orders. Those will tell you whether 2028 is a realistic marker or wishful thinking.

Bottom line: Corning is trying to be remembered as an AI infrastructure name, and Jefferies just helped make that case. The story is strong, the price is still demanding, and the entry point matters more than the headline.
