Lime's IPO filing shows a rare micromobility survivor with real revenue, real cash generation, and a debt schedule that gives it very little room to miss.
The electric scooter wars claimed Bird, Spin's independence, and most of the optimism that surrounded the sector's VC-fueled peak. Lime survived. Now it wants to go public, and the S-1 Neutron Holdings filed on May 8 tells you exactly how thin the margin between survival and collapse actually was.
Neutron Holdings Inc., the legal entity behind Lime, plans to list on the Nasdaq Global Select Market under the ticker LIME. Goldman Sachs and JPMorgan are running the books. The filing didn't set a price range or share count, but the Financial Times reported that Lime was hoping to list at a roughly $2 billion valuation. Uber, which became a major Lime shareholder after transferring its Jump bike business to the company in 2020, is already more than a backer. It is part of the distribution system.
The revenue trajectory is real. Lime went from $521 million in 2023 to $686.6 million in 2024 to $886.7 million in 2025, according to the filing, a 29.1% year-over-year increase on the top line. Adjusted EBITDA climbed from $153 million to $218 million over the same period. Free cash flow reached $103.8 million in 2025. In a sector where Bird filed for Chapter 11 in 2023 after going public through a SPAC, those numbers stand out.
But read the S-1 more carefully and the picture gets uncomfortable fast. Lime had $261 million in cash and cash equivalents at the end of March, while MarketWatch noted that it faces $675.8 million in principal payments on convertible notes and a term loan by the end of 2026. The filing includes going-concern language, saying substantial doubt exists about the company's ability to continue operating without raising funds through the IPO or finding another way to deal with the debt. That isn't a footnote you can wave away. It is the filing, in plain language.
This is why the IPO proceeds matter. Lime isn't just coming to market because investors finally learned to love green bikes parked outside train stations. It needs public-market money to fix a balance sheet built during a much looser funding era. Frankly, the most important number here isn't the $886.7 million in revenue. It's the gap between the cash Lime has and the obligations coming due.
Uber Is Not Just Along For The Ride
Uber's role deserves a harder look. The MarketWatch report said Uber-related activity accounted for 14% to 16% of Lime's annual revenue, and Lime rides already appear inside Uber's app in some markets. That makes the relationship more than a cap table item. You open Uber, see the short trip, and the app can push you toward a bike or scooter instead of a car. That's not a side business. That's how a ride-hailing platform keeps the customer even when the trip is too small for a driver to make sense.
If Lime prices well, Uber gets a stronger partner and a marked-up stake. If the IPO struggles, Uber still has a commercial reason to care. It doesn't need to believe every scooter parked in London or Paris is a beautiful business on its own. It only needs to believe that owning the customer interface matters, and that Lime helps it keep that interface when the journey is one mile, not ten.
That is the strategic bet investors have to separate from the rescue financing. Lime's management will sell the public market on a standalone business with durable unit economics, not a distressed asset waiting for a buyer. The adjusted EBITDA and positive free cash flow are the best evidence for that pitch. The awkward part is just as clear: net losses widened from $33.9 million in 2024 to $59.3 million in 2025 even as revenue grew.
The Filing Has Two Stories
One story is the survivor story. Lime operates in about 230 cities, according to MarketWatch, and the Financial Times reported that its bright green bikes and scooters have become common in cities such as London and Paris. Axios noted that Lime has expanded into more than 20 cities in recent years, including Tokyo and Athens. The company got through the micromobility shakeout with more scale than most of the companies that once looked like peers.
The other story is the debt story, and you shouldn't let the first one obscure it. The company says its ability to continue as a going concern depends on raising funds through the IPO or amending and refinancing its obligations. That is not the usual growth-company risk factor dressed up in legal language. It is a clock.
Micromobility has not had a clean public-market win at scale. Bird tried the SPAC route and collapsed. Lime is arriving with better revenue, better cash generation, and a platform partner in Uber, but also with a debt maturity schedule that gives the roadshow very little room to go badly. If the IPO prices and closes, Lime buys time. If it doesn't, the S-1 has already told you what comes next.
The roadshow is underway now. The answer should be known before summer ends.
