This is a routine promotional filing with no new deal terms or regulatory updates. The flurry of 425 communications suggests management is actively courting media and investor attention ahead of the shareholder vote. Watch for the definitive proxy statement/prospectus filing, which will contain audited financials and the record date for the shareholder meeting.

Executive Summary
ACP Holdings Acquisition Corp. filed a Rule 425 communication consisting of a media pitch email sent to journalists on September 16, 2026, promoting the proposed business combination with autonomous vehicle company May Mobility, Inc. The filing reiterates May Mobility's operational highlights (550,000+ autonomous rides, partnerships with Uber/Lyft/Grab/CaoCao and Toyota) and its 'asset-light' AaaS model, but contains no new financial terms, regulatory updates, or changes to deal structure — it is purely promotional.
Key Financial Metrics
Key Facts
- May Mobility has completed over 550,000 commercial autonomous rides across 1 million miles in the US and Japan.
- May Mobility is partnered with four ride-hail companies: Uber, Lyft, Grab, and CaoCao, plus Toyota, NTT, and ECARX.
- The combined company is expected to trade on Nasdaq under the ticker 'MAY'.
- Enterprise value is stated as '$XX billion' — a placeholder amount, not a specific figure.
- This is the fourth 425 filing in two days, all promoting the same deal with no new substantive information.
Financial Impact
No new financial figures disclosed; enterprise value placeholder remains $XX billion.
Risk Factors
- SPAC deal completion risk — shareholder redemptions could reduce trust account proceeds below the minimum required.
- No updated financials or guidance — the promotional tone may mask underlying business challenges.
- Enterprise value placeholder ($XX billion) suggests terms are still being finalized or not publicly disclosed.
