What is this Case About: Amgen Inc. (AMGN) Failed to Disclose the Impact of the Company's Tax Liability to Investors

According to the complaint, for years, Amgen has been accused of improperly skirting U.S. tax laws and relying on a profit allocation system that ran afoul of the U.S tax code, with the implication of owing billions in back taxes.

By the start of the class period, and after years of Amgen’s failed attempts to avoid receiving notices of deficiency, which would ultimately put the Company on the hook for over $10 billion in taxes and penalties, defendants were compelled to make substantial disclosures regarding the Company’s outstanding tax liabilities to investors. Rather than disclose these adverse facts, however, defendants failed to take any meaningful accrual or otherwise reveal the staggering amount of back taxes and penalties claimed by the U.S. government. These material omissions caused the price of Amgen stock to trade at artificially inflated prices throughout the class period, ultimately causing investors to suffer hundreds of millions of dollars in losses when Amgen belatedly revealed the truth.
