Plug Power Inc also took time in its most recent earnings report to reaffirm its outlook for the first quarter of 2018. The company is expecting revenue for the quarter to range from $22 million to $24 million. This will have the company falling short of Wall Street’s revenue estimate of $27.40 million for the period.
