MERCURY SYSTEMS INVESTOR ALERT: Kaplan Fox & Kilsheimer LLP Notifies Mercury Investors of a Class Action Lawsuit and Upcoming Deadline

Kaplan Fox & Kilsheimer LLP reminds investors that a complaint has been filed on behalf of purchasers or acquirers of the common stock of Mercury Systems, Inc. (“Mercury” or the “Company”) (NASDAQ: MRCY) between December 7, 2020 and June 23, 2023, inclusive (the “Class Period”). Click Here to Join the Action.

According to the complaint, on July 26, 2022, Glasshouse Research published a report alleging that: (i) Mercury overstated organic growth; (ii) the company’s acquisition of Physical Optics Corporation had been a “disaster” which was used to obscure Mercury’s financial results; (iii) IMPACT, Mercury’s highly touted strategic growth initiative, was a failure; and (iv) Mercury’s management prematurely recognized revenue on significant projects to artificially boost both revenue and earnings unsustainably, which also caused the Company’s working capital and unbilled receivables to balloon far beyond industry norms.

Following this news, Mercury’s stock price fell $4.87 per share, or 7.8%, to close at $57.26 per share on July 26, 2022. 

Then, on May 2, 2023 after the market closed, according to the complaint, Mercury announced weak third quarter 2023 earnings and lower margins that caused the Company to slash its full year 2023 guidance. 

Following this news, Mercury’s stock price fell $7.84 per share, or 17.3%, to close at $37.44 per share on May 3, 2023.

Finally, on June 23, 2023, according to the complaint, Mercury disclosed the resignation of its Chief Executive Officer, Mark Aslett, and that the Company’s recent strategic review of acquisition alternatives did not result in the sale of the Company. 

Following this news, Mercury’s stock price fell $3.37 per share, or approximately 9.6%, to close at $31.50 per share on June 26, 2023.

If you are a member of the proposed Class, you may move the court no later than February 12, 2024 to serve as a lead plaintiff for the purported class.  If you have losses, we encourage you to contact us to learn more about the lead plaintiff process.
