Plug Power delivered solid figures in the first quarter. Revenue rose 11% to USD 134 million, driven by electrolysers, material handling and cryogenic technology. Nevertheless, profitability remains the big challenge. Loss per share was USD 0.21, which was better than in the previous year but below analysts&ampCloseCurlyQuote; expectations. The gross margin improved significantly from -132% to -55% thanks to cost reductions and more efficient supply chains. However, there is still a long way to go before the Company returns to profitability. This remains a critical issue for investors, even if the Company is heading in the right direction.
