On September 4, Corning rose 3.45% in regular trading, trading at $149.85 per share, with turnover of $173 million. The rally was supported by news that Corning has committed to expanding its manufacturing capacity in South Korea as part of a broader $2 billion investment pledge by four US companies targeting semiconductor materials, display advanced materials, and offshore wind sectors.

Specifically, Corning plans to scale up its Korean operations, reinforcing its strategic presence in a region critical to display and semiconductor supply chains. The company currently generates approximately 45.3% of its revenue from optical communications, with display technologies and specialty materials forming additional core segments. The move signals continued international expansion despite recent headwinds from multiple investment banks lowering their target prices on September 1, when the stock fell over 3% amid concerns over slowing optical communications growth and elevated valuations above 67 times earnings.

Within the Electronic Components sector, peers showed broad strength, with Coherent up 2.84%, Vishay Intertechnology up 1.87%, and Littelfuse up 1.41%.
