Background on the Inogen Securities Class Litigation

Inogen is a Goleta, California-based medical technology company that develops and manufactures portable oxygen concentrators used to deliver supplemental long-term oxygen therapy to people with chronic respiratory conditions.

The action alleges that, throughout the Class Period, Inogen and certain of its senior executives made materially false and misleading statements regarding the strength of Companys business to inflate its stock price, including the size of Inogens total addressable market (TAM) and the growth of the oxygen therapy market in general.

On February 8, 2019, stock research analyst and short-seller Carson Block of Muddy Waters published a detailed report challenging Inogens TAM, arguing that it was far smaller than Inogen claimed, and that Inogens TAM was shrinking.

On February 26, 2019, Inogen issued a press release announcing its fourth quarter and fiscal year 2018 financial results, which significantly reduced its previously provided fiscal 2019 net income guidance. During a conference call discussing the results, Inogen Chief Executive Officer Scott Wilkinson backtracked on the Companys prior TAM estimates. On this news, the price of Inogen stock declined by $33.78 over the next trading day, or 24.11% from its previous close, to close at $106.28 per share on February 27, 2019, on extremely high trading volume.
