It's both good and bad, the good news is they will greatly expand their reach as they are breaking into Canada, maybe the UK and Japan by the end of next year, and the IPO will bring them the capital to enter into those new markets and maintain their operations in the USA and China. The bad news is they will have to appease their shareholders, and a bad quarter, or a back to back bad quarters could lead to higher prices for the consumer.
It all depends on how they manage their operations, as private entities as they are now don't have to open their books to show how profitable or how in the red they may be. Myself, I will try to get some shares of the IPO if they are priced decent and if its available as sometimes getting IPO shares is tough depending on the amount of shares offered and how they are distributed.
