Simply Wall St

Q4 earnings turn profitable as full year stays in the red

Quanex Building Products (NX) just posted a profitable fourth quarter while still closing fiscal 2025 with a sizable net loss and cautious, flat guidance for 2026, a mix that has investors reassessing the stock.

See our latest analysis for Quanex Building Products.

The upbeat fourth quarter has sparked a sharp near term reset in sentiment, with a 1 month share price return of 25.34 percent and a 7 day gain of 19.28 percent. However, the latest $16.52 share price still sits against a 1 year total shareholder return of minus 40.51 percent and weaker multi year performance, suggesting momentum is rebuilding from a low base as investors weigh the earnings recovery against cautious 2026 guidance and ongoing macro risks.

If Quanex's rebound has you rethinking where the next leg of growth could come from, it might be worth exploring fast growing stocks with high insider ownership as a fresh hunting ground for ideas.

With the shares still well below analyst targets but the outlook calling for flat earnings, investors face a dilemma: is Quanex quietly undervalued here, or has the market already priced in any future recovery?
