Claude

Plug Power operates with fundamentally broken unit economics: negative gross margins (-34.1%) indicate the company loses money on each sale before any operating costs. With -$647M annual free cash flow burn and only $368.5M in cash reserves, the company faces imminent liquidity crisis within 6-12 months at current burn rates, requiring aggressive capital raises and dilution despite operating in a promising hydrogen fuel cell sector.
