Summary: The United States of America has filed a lawsuit in the Southern District of New York against billionaire businessman and investor Joseph Lewis, Patrick O'Connor, and Bryan "Marty" Waugh. The defendants are accused of violating securities laws through insider trading and submitting misleading filings to the United States Securities and Exchange Commission (SEC) from 2013 to 2021. The lawsuit alleges that Lewis misused confidential information from publicly traded companies in which he was a significant investor. This information included non-public details about the companies' financial outlook, planned announcements, and clinical trial results. Lewis is accused of using this information to guide the trading activities of his associates, including O'Connor and Waugh, as well as personal assistants, romantic partners, and other acquaintances. The lawsuit implicates three companies: AAC, Solid Biosciences (SLDB), and Mirati Therapeutics. Lewis allegedly received confidential information about AAC's significant financial losses due to flooding and advised O'Connor and Waugh to sell their AAC stock. In the case of SLDB, Lewis is accused of using confidential information about a planned private investment in public equity (PIPE) transaction and a clinical trial to advise his girlfriend, O'Connor, and Waugh to buy SLDB stock. For Mirati Therapeutics, Lewis allegedly used non-public information from a Hedge Fund employee on Mirati's board to his advantage in trading Mirati stock. Additionally, Lewis is accused of conspiring to conceal his ownership of a pharmaceutical company's shares through a series of false filings and misleading statements. He allegedly evaded Canadian share ownership rules and SEC reporting requirements by buying Mirati shares through offshore shell entities under his control. Despite owning more than 19.99 percent of Mirati's stock, Lewis falsely reported to the SEC that he owned less than 19.99 percent. The lawsuit also includes allegations of a potential business combination between BCTG Acquisition Corporation, a special purpose acquisition company created by the hedge fund, and Tango Therapeutics, a privately owned life sciences company. Lewis allegedly disclosed confidential information about this potential business combination to O'Connor and Waugh, who subsequently purchased BCTG stock. The charges span from at least February 2019 to at least September 2021. The defendants are charged with conspiracy to commit securities fraud, including securities fraud, in violation of various sections of the United States Code and Code of Federal Regulations. The indictment details several overt acts committed in furtherance of the conspiracy, including the sale and purchase of various stocks.
