What happened
Shares of Plug Power (PLUG -2.86%) jumped as much as 14.9% in trading on Monday after the company announced a big contract. At 11:25 a.m. EST today, shares were still up 13.3%.
The big news was a $172 million contract to supply its GenDrive fuel cell power; GenFuel hydrogen, storage, and dispensing infrastructure, and other support to a Fortune 100 customer.
So what
This is one of the biggest contracts Plug Power has signed but is still about one-third the size of the deals done with Amazon.com and Walmart three years ago.
A contract like this is a step toward Plug Power reaching its goal of having $1 billion in gross billings by 2024, but doesn't say anything about its profitability. You can see in the chart below that deals with Amazon and Walmart have helped revenue, but Plug Power continues to lose nearly $100 million per year. If that doesn't turn around, the contract size doesn't matter.
Now what
Until Plug Power proves it can make money selling fuel cells, fuel, and services, I will take a skeptical view of the stock. Management has used share sales, which dilute shareholders, to patch over financial losses year after year. Scale hasn't seemed to help in the past, so I doubt that more sales will lead to better financial results.
