May Mobility has agreed to merge with ACP Holdings Acquisition Corp. (Nasdaq: ACGC) in a business combination valuing the autonomous vehicle technology company at an implied pro forma enterprise value of approximately $1.4 billion, creating a new route for investors to gain exposure to the increasingly competitive robotaxi and autonomous ride-hailing market.
The transaction, announced on September 16, 2026, is expected to provide May Mobility with gross proceeds of up to $337 million before transaction expenses and assuming no redemptions by ACP Holdings Acquisition Corp. shareholders. Once completed, the combined company is expected to retain the May Mobility name and list on Nasdaq under the ticker symbol MAY.
The deal arrives as autonomous driving companies move from technology demonstrations toward commercial deployments, while investors continue to scrutinise the enormous capital requirements associated with robotaxi development. May Mobility is attempting to differentiate itself through an asset-light model that relies on vehicle manufacturers, ride-hailing platforms and fleet partners rather than owning and operating a massive vehicle fleet itself.
How is the $1.4 billion May Mobility merger structured?
The proposed business combination gives May Mobility an implied pro forma enterprise value of approximately $1.4 billion. ACP Holdings Acquisition Corp. is expected to contribute as much as $217 million held in its trust account, although the eventual amount will depend on how many public shareholders choose to redeem their shares before the transaction closes.
A further $120 million will come from a fully committed private investment in public equity financing backed by institutional and strategic investors. An affiliate of Atlas Credit Partners, which is associated with ACP Holdings Acquisition Corp., is among the investors co-anchoring the financing.
The boards of both companies have unanimously approved the combination. Completion is targeted by the end of 2026 and remains subject to shareholder approvals, Nasdaq listing approval and customary closing conditions.
Why does May Mobility need fresh capital now?
May Mobility plans to use the transaction proceeds to accelerate research and development, expand autonomous deployments and reduce vehicle hardware costs as it pushes toward larger-scale commercial operations. Funding is also expected to support supply-chain investment, international expansion and additional working capital.
The company’s financial profile shows why access to additional capital matters. May Mobility generated approximately $10 million of revenue in 2025 with a gross margin of about 27%, while cash burn reached approximately $93 million as it continued developing its autonomous technology and expanding into new markets. Since its establishment in 2017, the company has secured approximately $445 million from venture investors, financial investors and strategic corporate partners.
The $1.4 billion valuation therefore reflects expectations for future commercial expansion rather than May Mobility’s current revenue base. That makes deployment growth, cost control and the conversion of partnerships into recurring revenue particularly important milestones once the company enters public markets.
What makes May Mobility different from other robotaxi companies?
May Mobility is promoting what it calls an Autonomy-as-a-Service model, under which partners can provide vehicles, fleet operations and customer platforms while May Mobility supplies the underlying autonomous driving technology. The approach is intended to reduce the capital intensity associated with purchasing and maintaining large proprietary vehicle fleets.
The company says it has completed more than 550,000 commercial autonomous rides covering approximately 1.1 million miles and has launched three driver-out operations in the United States. Its technology combines deep learning, a dynamic representation of the surrounding environment and real-time reasoning designed to allow vehicles to respond to complex road conditions.
May Mobility has also assembled partnerships across several parts of the mobility ecosystem. Toyota Motor Corporation is its principal automotive manufacturing partner, while Uber Technologies, Lyft, Grab Holdings and CaoCao have relationships covering autonomous ride-hailing deployments in different markets.
Could partnerships with Uber, Lyft and Grab accelerate May Mobility’s growth?
Ride-hailing partnerships are central to May Mobility’s expansion strategy because they provide access to established customer networks without requiring the autonomous technology company to build its own consumer platform from scratch. Uber Technologies and Lyft have entered multi-year arrangements with May Mobility covering autonomous vehicle deployments in the United States.
Grab Holdings has established a strategic partnership that includes investment, technology collaboration and plans for commercial expansion in Southeast Asia. CaoCao, meanwhile, is working with May Mobility on potential autonomous deployments in Europe and other international markets, with CaoCao expected to own and operate vehicles powered by May Mobility technology.
The company also has a significant relationship with NTT, which has participated in previous financing rounds and holds rights to operate May Mobility-powered fleets in Japan. A public autonomous vehicle pilot with NTT Mobility began in Nagoya in September 2026, adding an international test of the company’s technology outside the United States.
What should investors watch after the May Mobility and ACP Holdings merger?
The transaction gives May Mobility additional funding at a moment when autonomous vehicle developers are facing pressure to prove that years of investment can translate into sustainable commercial businesses. The company’s relatively modest 2025 revenue and substantial cash consumption mean that deployment growth will need to accelerate if May Mobility is to support the valuation attached to the combination.
Its partnership-driven model could reduce some of the capital burden compared with operators that own large robotaxi fleets, but May Mobility will still need significant investment in software development, vehicle integration, safety validation and industrialisation. Regulatory approvals and public acceptance of fully driverless services remain additional variables across the different markets the company intends to enter.
The planned Nasdaq listing will therefore turn May Mobility’s commercial progress into a more visible test of investor appetite for autonomous driving technology. If the transaction closes as expected, attention is likely to shift quickly from the $1.4 billion headline valuation toward ride volumes, deployment economics, revenue growth and how efficiently May Mobility can use the new capital to scale its autonomous ride-hailing platform.
