A class action lawsuit has been filed against Mercury Systems, Inc., (“Mercury Systems”, “Mercury” or the “Company”) (NASDAQ: MRCY) and certain of the Company’s top executive officers alleging that they violated the federal securities laws. The lawsuit seeks to represent all persons and entities who purchased or otherwise acquired Mercury securities between December 7, 2020, and June 23, 2023, both dates inclusive (the “Class Period”).

Mercury Systems is a technology company that produces component modules and subsystems for the aerospace and defense industries. Prior to and during the Class Period, Mercury was a serial acquirer that used acquisitions and improper revenue recognition practices to mask its inability to grow organically. During the Class Period, Defendants repeatedly touted the success of the Company’s growth, painting a false rosy financial picture for investors.

The lawsuit alleges that defendants repeatedly misled investors to believe that their growth was organic by misrepresenting several elements of Mercury’s business, including by hiding that Mercury had switched from “point-in-time” to “long-term contracts” in order to improperly boost reported revenues and that several of Mercury’s projects were in significant distress, including projects related to Mercury’s acquisition of Physical Optics Corporation. Mercury also lied to investors about its strategic growth initiative, 1MPACT, which was designed to improve profit margins but unbeknownst to investors was used to disguise regular expenses as restructuring costs, enabling Mercury to claim that recurring expenses were one-time costs.

The market was thus shocked when Glasshouse Research issued a short seller report on July 26, 2022, that revealed the truth of these issues. The issuance of the report from Glasshouse Research caused Mercury’s stock to drop 7.8%. The full truth of the state of Mercury’s business was then revealed piecemeal to the market through several partial disclosures that took place between July 26, 2022, and June 23, 2023. During this time, the Company’s share price declined nearly 50%, wiping out billions of dollars in market capitalization and damaging investors.
