Why Plug Power Stock Surged 26% in May But Is Falling Apart Again

Plug Power achieved its first-ever gross profit in Q1 2026, driving a 26% stock surge in May. The company's margins improved significantly through cost-cutting initiatives and vertical integration in hydrogen production. However, the stock has since cooled off. While analysts upgraded price targets to $5 and the company projects profitability by 2028, significant challenges remain including ongoing cash burn, execution risks, and the need to prove consistency after years of project delays.
