Initial Public Offerings: Eligibility, Application, Vetting and Listing

This domain tests the IPO timeline and the documents produced at each stage. Marks are lost by mixing up the Application Proof, the PHIP and the prospectus, and by missing the clawback mechanics.

The route to listing

  • Appoint a sponsor at least two months before filing; complete due diligence and any pre-IPO reorganisation.
  • File Form A1 with the Exchange and simultaneously publish the Application Proof, a substantially complete draft listing document, on the HKEX website. The application lapses after six months.
  • Vetting: the Listing Division reviews eligibility and disclosure, issues comment letters, and takes the case to the Listing Committee hearing. After the hearing, the Post Hearing Information Pack (PHIP) is published on the HKEX website.
  • Prospectus: authorised by the SFC and registered with the Registrar of Companies under the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32), then issued and circulated with the offer.
  • Offer, allotment, results announcement, admission to CCASS and commencement of dealing.

Offer structure and clawback

  • A placing tranche plus a Hong Kong public offer tranche. Under Practice Note 18, oversubscription of the public tranche triggers clawback from the placing tranche: 15 to 50 times gives 30%; 50 to 100 times gives 40%; 100 times or more gives 50%.
  • The 25% public float requirement must still be met after clawback and after any cornerstone allocations.
  • No public marketing before the prospectus is authorised; sponsor-group research is restricted during the process.

Worked example

An IPO's Hong Kong public offer tranche is 60 times oversubscribed. Clawback moves the tranche from its initial 10% to 40% of the offer. The placing tranche shrinks correspondingly, and the issuer must still show at least 25% of issued shares in public hands at listing, counting the clawed-back shares.

Traps that cost marks

  • Treating the PHIP as a prospectus; it is a post-hearing information pack, not an authorised document.
  • Filing a partial or skeleton Application Proof; it must be substantially complete.
  • Assuming SFC authorisation is a merit judgment on the investment; it is a disclosure and compliance check.
  • Forgetting the six-month lapse of the Form A1.
