Lime filed for a Nasdaq IPO in May 2026 targeting a $1.8 billion valuation, with Uber holding a 29% anchor stake and $886.7 million in 2025 revenue. But the S-1 contains a going-concern warning: the company has a $584.8 million liquidity shortfall and needs the IPO proceeds to repay $845 million in debt due this year. It is the first major micromobility public offering attempt in eight years, and it has almost no margin for error.
