Corning (GLW) Stock Falls After Amazon And Nvidia Fiber Deals And Q2 Beat

Never miss an important update on your stock portfolio and cut through the noise. Over 7 million investors trust Simply Wall St to stay informed where it matters for FREE.

• Corning (NYSE:GLW) reported strong Q2 2026 results, with solid contributions from its Optical Communications and Solar segments.

• The company announced new supply agreements with Amazon and NVIDIA that support expansion of U.S. optical fiber capacity.

• Despite the positive operational update, shares declined after the company issued Q3 guidance that did not meet analyst expectations.

Corning enters this news cycle with a share price of $143.36 and a very large 3‑year gain of about 7x. The stock is up 161.6% over the past year and 58.1% year to date, although it is down 6.4% over the past week and 35.1% over the past month. That mix of strong longer‑term gains and recent weakness frames how investors may read the latest earnings and partnership news.

For investors, the key questions now center on how these Amazon and NVIDIA agreements might support Corning’s optical fiber and related businesses in the U.S. The Q3 outlook has unsettled some expectations, so upcoming execution and any further contract details are likely to be important checkpoints for sentiment toward NYSE:GLW.
