Inogen, Inc. is a medical technology company offering lightweight portable oxygen concentrators.

According to the law firm press release, the lawsuit alleges the Company made false and/or misleading statements about the accuracy of Inogen’s financial statements and the effectiveness of Inogen’s disclosure controls and procedures. Furthermore, Inogen failed to disclose material weaknesses in its internal controls over financial reporting.

On March 11, 2015, the Company announced that management discovered potential accounting matters during the first quarter of 2015. This discovery prompted the Audit Committee, with the assistance of independent advisors, to investigate whether any of the Company’s accounting policies were violated stemming from these potential accounting matters. On this news, shares of Inogen fell $4.24 per share or over 11% to close at $33.10 per share on March 12, 2015, damaging investors.

This case was voluntarily dismissed on June 29, 2015.
