Plug Power Inc (NASDAQ:PLUG) stock has surged more than 4000% over the past year from a low of $0.15 last April to over $11 in February and is currently trading around $7. The run, according to the experts, is driven by the hope that the company will utilize its technology to enter the automotive and aviation industries.

Plug Power Inc (NASDAQ:PLUG) generated a small revenue from the services compared to the actual product sold, and at the same time the costs relating to these services are rising, according to the author. Though the increased orders may look great at this point of time, moving forward all the equipment will need maintenance, and the cost would affect the future earnings.

For Plug Power Inc (NASDAQ:PLUG) increase in product cost is not extraordinary with increase in the products sold due to direct overhead costs, but the fact that the cost is more than the profits is a cause of concern. According to some, the cost may come down with the recent purchase of ReliOn, but the effect of this purchase will not be evident before 2015 due to a supply agreement with Ballard Power system.

Not enough cash

At present, the company has around $73 million available to spend along with the cash and equivalents of $5 million as of December 31, 2013. This implies that the company will use around one third of their cash in 2014.  “This does not bode well for long-term survival unless additional capital is raised,” says the author.
