September 17, 2026 in numbers
Nucor Corp. (ISIN US6703461052, NYSE: NUE) issued updated guidance for its third quarter ending October 3, 2026, stating that it expects earnings per share to range between USD 3.30 and USD 3.60, below many analysts’ prior forecasts, according to a company statement reported by PR Newswire on September 17, 2026. In regular trading that day, the shares were quoted around USD 265.55, before sliding in after-hours dealings to roughly USD 255.16 as investors reacted to the softer outlook, per commentary from Investing.com. The after-hours level left the stock still well above a 52-week low of USD 131.32 but notably below a 52-week high of USD 280.11 reached earlier in the year, as highlighted by Investing.com Germany. While Nucor moved lower, broader US indices such as the Nasdaq Composite and S&P 500 closed higher on September 17, 2026, with the Nasdaq up about 1.7% and the S&P 500 gaining roughly 1.1%, as summarized in a market wrap by Mitrade, underscoring the stock’s underperformance versus the wider market.
Guidance focus today
Today, trading in Nucor is likely to remain centered on the implications of the third quarter 2026 earnings guidance, including how the projected earnings range reflects steel demand, pricing, and margins in the coming months, as framed in the guidance release carried by PR Newswire. Sector peers that also issued guidance below consensus, including other US steel producers mentioned in an Asia market recap by Saxo, may add context for investors comparing Nucor’s outlook with the broader industry. In addition, moves in energy and industrial commodity prices and the performance of major US indices could influence sentiment toward cyclical names such as Nucor over today’s session.
