Philip Morris International is a leading international tobacco and nicotine company operating in approximately 170 markets worldwide. The company generates revenue from three main business segments: cigarettes (including the Marlboro brand), smoke-free products such as heat-not-burn devices (IQOS), nicotine pouches (ZYN), and e-vapor products, and emerging wellness offerings. PMI distributes its products through direct sales to retailers, independent distributors, wholesalers, e-commerce, and company-owned retail infrastructure, with revenue concentrated among a small number of major distributors. The company's strategic focus is transitioning its business toward smoke-free products, which generate lower levels of harmful chemicals than traditional cigarettes, while maintaining its established cigarette business as a significant revenue source.
