Investors' belief that strong revenue growth is not on the horizon for Inogen contributes to its low P/S ratio. The company's underwhelming revenue outlook is a major factor. A change of fortune is needed to justify a higher P/S in the future.
$Inogen(INGN.US)$ An authorized Inogen dealer I work with said that Inogen G4s and G5s are failing more than half of the time forcing them to return them to Inogen. Inogen sells these devices directly to the public and I have to assume Innogen is not performing the additional testing that the dealer is doing or they would be finding the defective POCs before shipping. The specific defect mentioned is the device not recognizing the battery when AC power is disconnected. I would imagine that if the dealer is telling the truth (I have it in writing) there will be a recall on Inogen devices.
