Corning tumbles despite in-line to positive Q3 results and bright Q4 outlook

AI has been a source of surging demand for the 174-year-old company’s fiber-optic cables, which are used to help link servers in data centers.

Corning is tumbling even as the the 174-year-old glass maker and pioneer of Pyrex and fiber-optic cables reported in-line to positive Q3 results on Tuesday, along with a better-than-anticipated Q4 outlook.

Corning reported:

  • Core earnings per share of $0.67, in line with consensus expectations from analysts, according to Bloomberg.

  • Core sales of $4.27 billion vs. a $4.23 billion consensus expectation from analysts.

  • The company expects fourth-quarter core sales of about $4.35 billion compared to a consensus estimate of $4.29 billion from Wall Street, with core EPS between $0.68 and $0.72, the midpoint of which is also above Wall Street’s estimate of $0.68.

“The 4Q outlook suggests sustained AI-driven optical demand,” Bloomberg Intelligence analysts Woo Jin Ho and Kiran Jagtiani wrote.

However, the early reaction to these results suggests that while Corning continues to capture benefits from the AI data center building boom, it may take more to impress investors in light of its strong performance year to date.

Through the end of trading on Monday, Corning shares were up nearly 90% in 2025, as the company takes advantage of rising demand tied to the AI investment boom. That would be the best year for the stock since 2009, when it rose 103%.

SpaceX gets a wave of bullish ratings from Wall Street analysts

SpaceX received more than a dozen positive analyst calls on Tuesday — including from major Wall Street banks — as they initiate coverage on Elon Musk’s space and AI company.

SpaceX went public on June 12 at a $2.2 trillion valuation, the largest debut in history. While the company hasn’t yet posted a profit, it seems to have convinced Wall Street that it will get there and grow its valuation on the way.

Of the at least 17 analysts that gave a rating on Tuesday, all but one gave it a “buy” or “outperform” rating. MoffettNathanson was "neutral."

The ratings come as SpaceX joined the Nasdaq 100 index, a benchmark tech-heavy basket of companies that underpins millions of portfolios. The inclusion adds built-in demand for the stock from index funds and ETFs.

Still, SpaceX fell more than 5% on Tuesday amid a broader sell-off, and is currently effectively flat from its opening price of $150 a share.

Nike sinks to lowest level since 2014 after warning of “challenged” sales environment in Q4 report

Did Nike do it?

Investors had a mixed reaction after the global sports apparel company reported its fourth quarter earnings on Tuesday after the bell. Shares initially rose 5% as Nike beat out Wall Street expectations amid a hefty tariff refund bonus. However, the stock then sank to its lowest level since August 2014 in postmarket trading.

Here are the Q4 numbers:

  • Revenue of $11.0 billion (estimate: $10.8 billion).

  • Adjusted earnings per share of $0.20 (estimate: $0.12).

Ahead of this report, Nike warned that results would be flattered by a one-time tariff refund (now estimated at roughly $0.52 per share for the bottom line). That gave the company an extra cushion in snapping its streak of seven quarters of year-over-year profit declines.

Over the past year, the company had been punished by tariffs on imported goods, stagnant consumer spending, and increasing competition from other footwear brands like New Balance, Adidas, and Hoka.

Outgoing CFO Matthew Friend deemed it an “increasingly challenging operating environment, where sell-through remains challenged.”
