The ADGM SPV regime has a flexible ownership structure with no minimum share capital, no maximum number of shares or shareholders and no restriction on the nationality of shareholders. Multiple classes of shares are allowed so you can create different rights for different types of shareholders.
If an ADGM SPV is wholly-owned by GCC nationals, it is considered a GCC national for the purposes of onshore UAE foreign ownership restrictions (where minimum levels of UAE national ownership are set out in the law).
It is possible to incorporate an ADGM SPV with a sole director and a sole authorised signatory. The authorised signatory is subject to security clearance and must either have a UAE residence visa or a UAE entry stamp on their passport.
