May Mobility's $1.4B SPAC prices a 70% margin it has never earned
The robotaxi operator agreed to list at roughly $1.4 billion on $10 million of 2025 revenue and a 27% gross margin. The firmest money in the deal arrives as preferred stock with a 12% coupon, and the trust behind the rest can be pulled at the vote.

The trust can shrink even if the vote passes
The money behind this merger belongs, in order, to people who can take it back. ACP Holdings' public shareholders hold up to $217 million of the up to $337 million in gross proceeds promised in the 16 September announcement, and every dollar is redeemable 12. They can vote the deal through and redeem anyway, which means the trust can shrink toward zero on vote day 2.
Each redeemed dollar comes off May Mobility's runway. The sellers' price does not move: the merger agreement fixes consideration at $1.35 billion in stock, against a pro forma enterprise value near $1.4 billion, with a Nasdaq listing as MAY targeted by year-end 13.
The coupon lines up ahead of common
The other pot, a fully committed $120 million PIPE, is firmer and costs more. It buys Series A cumulative convertible preferred at a $12.00 stated value carrying a 12% cumulative coupon 45. Warrants covering 100% of the conversion shares at the same $12.00 strike run five years 4; on conversion the PIPE can roughly double its claim on common, and the extra shares land on holders who already sit behind the coupon.
Closing requires trust cash plus PIPE proceeds of at least $120 million, exactly the PIPE's size 3. That floor is what makes trust retention the deal's real variable.
The multiple is 140 times revenue
Last year the fleet produced about $10 million of revenue at a 27% gross margin, with cash burn equal to 9.3x revenue 1. Non-GAAP operating expenses ran $81 million 6. The margins that justify the multiple, up to 70% gross and 30% EBIT, are labeled illustrative, and the same disclosures concede the fleet-operator revenue-share model behind them has yet to generate material revenue 16.

The cohort has been repriced since July
May is also entering a cohort the public market has spent the summer marking down. Momenta listed in July at an $8.9 billion valuation and sat near $5.2 billion by a 26 September tally, even after posting a 75% gross margin on 1.6 billion yuan of first-half revenue 78. WeRide trades near $1.85 billion and Pony.ai near $2.95 billion 7.

The partners are real; the revenue-share is not
The fleet behind the pitch is not the weak point: Toyota Siennas have carried more than 550,000 paid autonomous rides over 1.1 million miles, with paying riders on Lyft in Atlanta and in two Minnesota cities 12. Uber, Lyft, Grab and CaoCao carry demand, and NTT operates Japan exclusively 1. The company counts its three driver-out deployments against about $0.3 billion of capital, versus the $11.3 billion-plus Waymo raised to the same milestone 6. What is missing is the revenue that would make the software comparison true.
Watch the proxy, not the press release
Three documents decide the next six months: the S-4 with audited financials, the redemption count at the vote, and the certificate of designation that fixes the coupon 34. The PIPE can grow by up to $50 million, with prefunding due 30 September 2026 4. Arlington, Texas opens with Uber in Q4 2026 or Q1 2027 19. A yes vote is not a wire.
