The Full Form of OFS is Offers for Sale.

Offer for sale (OFS) is a simpler method of share sale through the exchange platform for listed companies. The mechanism was first introduced by India’s securities market regulator Sebi, in 2012, to make it easier for promoters of publicly-traded companies to cut their holdings and comply with the minimum public shareholding norms by June 2013. The method was largely adopted by listed companies, both state-run and private, to adhere to the Sebi order. Later, the government started using this route to divest its shareholding in public sector enterprises.
