Corning stock closed at USD 153.21 on the NYSE on September 23, 2026, down 3.63 percent from the prior close. The move contrasted with the Nasdaq, which gained 0.5 percent to end at 27,244.28 on the same date.
September 23, 2026 in numbers
Corning Inc. (ISIN US2193501051, NYSE: GLW) traded lower during the session after reports focused on a USD 2 billion at-the-market share distribution agreement with Goldman Sachs. Mitrade reported that investors were assessing potential dilution to existing shares and earnings per share. The stock therefore underperformed the Nasdaq by 4.13 percentage points.
Earlier market data had placed Corning at USD 159.67 on September 23, 2026, up 0.43 percent from the September 22 close, but that quote was intraday and did not represent the completed regular-session close. Ad Hoc News identified the earlier figure as market data for the session.
