Any idea of listed companies in Auditing Space?

Any idea of listed companies in Auditing Space?? the proposed companies Act Bill tries to reduce the monopoly of 4 biggest companies {PWC, Deloitte, …}, if succeeded this move will help the indian listed auditing players a lot.

now these big 4 firms have captured 55% of the entire indian listed companies auditing requirements.

Even if govt opens up, it means the sector will now be open to even smaller players. Which will get commoditized in a way. And this has likely impact on the quality of auditing.
