According to regulatory disclosures, the transaction will increase PhysicsWallah's shareholding in the company from 40% to 51%, turning Sarrthi IAS into a subsidiary.
PhysicsWallah has completed the second tranche of its acquisition of Guiding Light Education Technologies, the parent company behind Sarrthi IAS. As part of this round, the board approved an addendum to the share purchase agreement, revising the valuation method and purchase consideration while keeping all other terms unchanged.

Under the terms of the transaction, PhysicsWallah will acquire an additional 1,100 equity shares, representing an 11% stake, for an aggregate consideration of Rs 71.81 crore.
