Where there's smoke, there's Philip Morris USA (PM USA). A subsidiary of tobacco giant Altria Group, PM USA is the #1 US cigarette maker. The company also dominates half of the nation's retail cigarette market. Its Marlboro brand alone accounts for about 45% of cigarette retail sales in the country. Other brands include Virginia Slims and Parliament; its discount cigarettes are sold under the Basic and L&M names. PM USA also makes smokeless tobacco products, including Marlboro Snus. Altogether, cigarettes generate nearly 85% of its parent's revenues. Like industry rivals, PM USA faces declining cigarette sales volumes paired with rising state and federal excise taxes and FDA regulation.
