Altria Group's stock plummeted 5.01% during intraday trading on Thursday, following the release of its fourth-quarter financial results.

The maker of Marlboro cigarettes reported adjusted earnings per share of $1.30 for the quarter, missing analysts' consensus estimate of $1.32. Revenue fell 2.1% year-over-year to $5.85 billion, with the smokeable products segment showing particular weakness due to lower shipment volumes and higher promotional investments.

Adding to investor concerns, Altria's oral tobacco segment saw shipment volumes decrease 6.3%, driven by market share losses across its product line. The company's performance in these key business areas disappointed investors, leading to the significant stock price decline.
