Sebi's investigation into Vinod Adani's control over offshore investments in Adani group companies has concluded. The regulator found insufficient evidence to support allegations of minimum public shareholding violations. Vinod Adani was not proven to have effective control over certain foreign portfolio investors. Relationships among parties involved did not demonstrate direct control or influence over investment decisions. Consequently, the case against Vinod Adani was closed due to lack of definitive evidence.
