Alphageo (India) Limited (AGIL) has announced that its subsidiary, Alphageo Offshore Services Private Limited (AOSPL), has ceased to be a subsidiary of AGIL. This change is effective from September 18, 2026.
The cessation occurred because AGIL renounced its entitlement in a Rights Issue undertaken by AOSPL. Consequently, AGIL's shareholding in AOSPL was diluted to below 51%, leading to a loss of control and AOSPL no longer qualifying as a subsidiary.
Prior to this, AGIL held more than 51% of AOSPL's shares. Following the renunciation and dilution, AGIL's post-holding is less than 51%. The company has made this disclosure in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015.
