US markets open mixed as earnings season heats up, with General Motors (GM) and Coca-Cola (KO) topping estimates while warning of tariffs and shifting consumer demand. GM stock jumped more than 10% after raising full-year guidance, driven by strong truck sales and tariff relief measures that offset $4.5B in costs. CEO Mary Barra struck an optimistic tone, calling new policies “a win for American manufacturers.” Coca-Cola beat expectations but noted slowing demand for soft drinks, while its zero-sugar and sports drink lines showed double-digit growth. Aerospace and defense stocks, including General Electric (GE), RTX (RTX), and Lockheed Martin (LMT), rose after strong commercial and defense demand prompted guidance hikes. Meanwhile, Warner Bros. Discovery (WBD) confirmed it’s reviewing strategic alternatives following takeover interest from multiple parties, including Paramount Global (PARA). The company said it remains committed to splitting into two divisions by mid-2025 but is open to offers for its studio business.
