Sun Pharma also emerged as the biggest gainer in the Sensex pack.

“Sun Pharma’s distribution related to India’s domestic formulations business shall be transitioned from Aditya Medisales Ltd, the current distributor, to a wholly-owned subsidiary of Sun Pharma,” the company said in a regulatory filing.

Sun Pharma said this change will be made effective by first quarter of 2019-20, post receipt of all requisite regulatory approvals.

The company also announced unwinding of a transaction amounting to Rs 2,238 crore with Atlas Global Trading and initiated steps to induct SRBC & Co LLP, its statutory auditors, as auditors of subsidiaries.

The shares were under pressure amid reports of a whistleblower complaint against the company.

According to reports, a second whistleblower complaint was filed against the firm earlier this month. Besides, a whistleblower in November last year approached the Securities and Exchange Board of India (Sebi) with a document alleging various irregularities by the company, its promoter and others.

Sun Pharma wrote to Sebi last week flagging concerns that certain entities were allegedly adopting unfair trade practices.
