Inogen to File Form 12b-25 With Securities and Exchange Commission

GOLETA, Calif., March 31, 2015 (GLOBE NEWSWIRE) -- Inogen, Inc. (Nasdaq:INGN), a medical technology company offering innovative respiratory products for use in the home care setting, announced today that it will file a Form 12b-25 Notification of Late Filing with the U.S. Securities and Exchange Commission with regard to its Annual Report on Form 10-K for the year ended December 31, 2014. The filing provides the Company with an additional 15 calendar days to file its Form 10-K.

The Company was unable to file its Form 10-K by the March 31, 2015 deadline because the Company has not finalized an ongoing internal investigation regarding certain potential accounting matters that were discovered by management. Specifically, the Audit Committee, with the assistance of independent advisors, is currently investigating whether there were any violations of the Company's accounting policies associated with these potential accounting matters. Consequently, the Company is not in a position to file its Form 10-K until after the completion of the Audit Committee's investigation. However, the Company expects to be able to complete its Form 10-K by the extended deadline of April 15, 2015.

Inogen has used, and intends to continue to use, its Investor Relations website,, as means of disclosing material non-public information and for complying with its disclosure obligations under Regulation FD. For more information, visit
