According to the lawsuit, defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (1) there were irregularities in the clinical experiments that underpin Philip Morris' application to the FDA for approval of its iQOS smoking device; and (2) as a result, defendants' statements about Philip Morris' business, operations and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times. When the true details entered the market, the lawsuit claims that investors suffered damages.
