Alliant Energy shares traded higher during the regular session, supported by the company's recent reaffirmation of its 2026 ongoing EPS guidance and its focus on long-term grid infrastructure projects. This positive sentiment was bolstered by broader sector trends, as the stock outperformed several peers like WEC Energy and OGE Energy while matching the gains seen in DTE Energy. The move also occurred as the broader market clawed back earlier losses following a retreat in Treasury yields, providing a stable backdrop for regulated electric utilities.
