TransDigm Group, Inc. [NYSE: TDG]

Federman & Sherwood Announces the Filing of a Securities Class Action Lawsuit against TransDigm Group, Inc.

Oklahoma City, OK (August 11, 2017) – On August 10, 2017, a securities class action lawsuit was filed in the United States District Court for the Northern District of Ohio against TransDigm Group, Inc. (NYSE: TDG). The complaint alleges violations of federal securities laws, Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, including allegations of issuing a series of material or false misrepresentations to the market which had the effect of artificially inflating the market price during the Class Period, which is May 10, 2016 through January 19, 2017. More specifically, this litigation was filed because defendants made false and/or misleading statements and/or failed to disclose that: (1) TransDigm’s growth and profitability were artificially inflated as a result of its illicit business practices; (2) TransDigm used exclusive distributors to make noncompetitive government bids seems competitive; (3) TransDigm subsidiaries failed to list TransDigm as a parent entity when submitting government bids; and (4) as a result, defendants’ statements about TransDigm’s business, operations, and prospects were false and misleading and/or lacked a reasonable basis. When the true details entered the market, the lawsuit claims that investors suffered damages.

On January 20, 2017, Citron Research issued a report accusing TransDigm of being the “Valeant of the aerospace industry.” The report disclosed that the Company uses multiple shell distributors that have no pricing power to avoid detection by making government bids seems competitive. Citron further emphasized that TransDigm’s growth was driven, in large part, by rampant acquisitions and extreme debt levels.

On this news, TransDigm’s share price dropped $24.86 per share from $251.76 per share on January 19, 2017 to $226.90 per share on January 20, 2017.

Plaintiff seeks to recover damages on behalf of all TransDigm Group, Inc. shareholders who purchased common stock during the Class Period and are therefore a member of the Class as described above. You may move the Court no later than Tuesday, October 10, 2017 to serve as a lead plaintiff for the entire Class. However, in order to do so, you must meet certain legal requirements pursuant to the Private Securities Litigation Reform Act of 1995.
