Here are the S-3 shelf registrations from Ambow Education Holding Ltd. (AMBO) in our archive over the last 12 months, newest first, and each one links through to the document itself with the summary and the scores our analysis gives it.
An S-3 covers the shelf registration that lets an established company sell over time, so if you follow AMBO and want that one kind of document rather than the whole filing history, this is the page to keep. The company's other filings, of every form, are on the full AMBO filings page.
Ambow Education Holding Ltd., a Cayman Islands company focused on AI-powered “phygital” education and collaboration solutions, has filed a shelf registration to offer up to $100,000,000 of ADSs, Class A ordinary shares, preferred shares, warrants, subscription rights, debt securities and units. Each ADS represents 20 Class A ordinary shares. Specific terms and prices will be set in future prospectus supplements and sales may occur through underwriters, agents, dealers or direct placements.
As of July 21, 2026, ADSs traded on the NYSE American under “AMBO” at $2.34 per ADS and the aggregate market value of voting and non-voting equity held by non‑affiliates was about $4.30 million; sales under this shelf are therefore subject to the one‑third limitation in General Instruction I.B.6 while non‑affiliate market value remains below $75 million. Ambow reported net revenues of $9.4 million in 2024 and $9.5 million in 2025, with gross margins improving from 53.1% to 54.8%, driven by its HybriU platform. The company settled a campus lease dispute for $2.0 million payable over two years and is contesting an employment lawsuit whose ultimate impact cannot be estimated.
Ambow highlights risks including HFCA Act-related potential for future ADS delisting if PCAOB access to its China-based auditor is restricted, industry competition, regulatory changes and ongoing legal proceedings. Net proceeds from any offerings are expected to be used for business growth, working capital, general corporate purposes and possible acquisitions.
