Mentioned:May MobilityACP Holdings Acquisition Corp.UberLyft$1.4B · Public Markets
May Mobility, which develops autonomy-as-a-service technology for commercial ride-sharing, is going public through a SPAC merger with ACP Holdings Acquisition Corp. at a $1.4 billion enterprise value. The deal will raise up to $337 million in gross proceeds, including $217 million from the trust account and a $120 million PIPE from institutional and strategic investors.
What's happening
- May Mobility will merge with ACP Holdings at a $1.4B pro forma enterprise value and trade on Nasdaq under ticker MAY, expected to close by end of 2026.
- The company has completed over 550,000 commercial autonomous rides covering 1.1 million miles in the U.S. and Japan, with 3 driver-out deployments in the United States.
- May Mobility operates commercially in 3 U.S. locations with Lyft in Atlanta and on-demand services in Eden Prairie and Grand Rapids, Minnesota.
- The company generated approximately $10 million in revenue during 2025 with a 27% gross margin while burning $93 million in annual cash.
Why it matters
- May Mobility's licensing model reduces capital intensity compared to autonomous vehicle operators that own fleets, targeting 70% gross margins and 30% EBIT margins long-term.
- Partnerships with Uber, Lyft, Toyota, Grab and NTT provide commercial revenue channels and manufacturing scale, reducing development and deployment risk.
- The company's multi-policy reasoning architecture enables market entry without collecting millions of location-specific training miles, accelerating geographic expansion and reducing go-to-market costs.
- Public capital enables funding for supply-chain investments and international deployments while supporting expansion of driver-out capabilities across multiple cities.
Going deeper
- May Mobility claims to be the first U.S. publicly listed pure-play autonomous ride-hail technology company focused on licensing rather than fleet ownership.
- The company is targeting commercial operations with Uber in Arlington, Texas in Q4 2026 or Q1 2027 and is expanding with NTT Mobility in Japan starting September 2026.
- Since founding in 2017, May Mobility has raised approximately $445 million from venture investors, corporate partners and financial investors prior to this public offering.
Financial impact
- May Mobility will receive gross proceeds of up to $337 million, comprising $217 million from ACP's trust account subject to shareholder redemptions and $120 million fully committed PIPE funding.
- The $337 million in gross proceeds will fund research and development, industrialization, driver-out system expansion, supply-chain investments and general working capital, with proceeds received upon closing expected end of 2026.
- May Mobility reported $10 million in revenue during 2025 and $93 million in annual cash burn, indicating funding runway will depend on revenue growth trajectories and deployment timelines.
The intrigue
- May Mobility's success depends on scaling licensing revenue with Uber and Lyft while entering new geographies without repeating expensive data collection in each market, an unproven capability at scale.
- The timing of Uber Arlington launch in Q4 2026 or Q1 2027 coincides with public market expectations, creating execution pressure immediately following the SPAC closing.
The fine print
- Transaction closing is subject to shareholder approvals, Nasdaq listing approval and other customary closing conditions, expected by end of 2026.
- ACP Holdings trust account proceeds of $217 million are subject to shareholder redemptions, which could reduce actual capital available to May Mobility.
