Why Is GENERAL MTRS CO (GM) Stock Down Today?

General Motors shares fell 6.84% to close at $77.09. The primary driver was a disappointing full-year profit outlook, which overshadowed the company’s third-quarter earnings beat.

What Happened

General Motors reported third-quarter revenue of $50.02 billion, exceeding estimates of $48.7 billion, and adjusted earnings per share of $3.70, which also beat expectations. Despite these top- and bottom-line beats, the stock declined sharply because the company warned of a rocky 2027. The CFO noted that prices for copper and some steel products have risen 10% to 15% since July, and commodity costs could worsen by $2 billion in 2027 if recent inflation trends hold. The board approved a new $20 billion multi-year buyback authorization with no expiration date, following the completion of a previous $6 billion program. Additionally, the company plans to introduce hybrid vehicles in multiple market segments as rising gasoline prices push consumers toward fuel efficiency.
