At the close on September 18, 2026, Corning stock finished at USD 150.13 on the New York Stock Exchange, up 1.58% for the session compared with the prior close, according to NYSE data in Nasdaq-listed overviews. The stock’s recovery left it still below the recent intraday high near USD 169.73 earlier in September, highlighting ongoing volatility after recent financing announcements.
September 18, 2026 in numbers
Corning Inc. (ISIN US2193501051, NYSE: GLW) closed the last completed session on the New York Stock Exchange at USD 150.13 on September 18, 2026, gaining 1.58% on the day after trading between an intraday low of about USD 147 and a high of roughly USD 151, per exchange data cited by market portals. The move came on volume of roughly 11.1 million shares, versus a 52-week trading range that runs from about USD 77.05 to USD 171.78, indicating that the latest close sits well above the lower end of the range but still below this month’s peak.
On the same day, the broader S&P 500 index advanced more modestly, so Corning’s 1.58% gain meant the stock outperformed the benchmark during the September 18, 2026 session. Recent price pressure earlier in the month followed Corning’s announcement of an at-the-market equity offering of up to USD 2 billion of common stock and subsequent investor investigations, with one law firm noting that the stock fell by 13.7% to close at USD 143.60 on September 14, 2026 after the offering disclosure, as National Law Review reported on September 20, 2026. A separate summary highlighted that Corning’s last close at USD 150.13 still lagged the post-announcement high near USD 165.96, underlining that the stock has only partly retraced the selloff, as ad-hoc-news summarized in a recent wrap.
Guidance and events in the coming days
Looking ahead, investors are monitoring Corning’s previously issued guidance for the third quarter of 2026, which called for earnings per share between USD 0.85 and USD 0.89, implying potential growth versus the reported second-quarter 2026 EPS of USD 0.78 if the company reaches the upper end of the range, as ad-hoc-news reported based on recent filings. While no specific earnings date within the next few days is highlighted in recent calendar overviews, the existing guidance range provides a reference point for expectations as the market evaluates the impact of the equity offering and new fiber supply agreements on Corning’s nearer-term performance.
