Tata Motors is the third Sensex company related to whom the regulator has passed an order in the high-profile case of leakage of sensitive financial details prior to formal announcement of quarterly results.
In a detailed order, the watchdog said that prima facie appears that the financial results of Tata Motors for quarter ended December 2015 were finalised on or before February 9, 2016, which was before circulation of WhatsApp message on February 11, 2016.
"Such resemblance of the information circulated on WhatsApp with the actual financial results prima facie indicates that the financial figures of Tata Motors, were in circulation prior to official announcement/ publication by Tata Motors," it added.
The watchdog has asked Tata Motors to conduct an internal inquiry into the leakage within three months to ascertain the possible role of any officials.
Besides, the auto maker has been asked to strengthen its processes to ensure that such instances of leakage of unpublished price sensitive information do not recur in future.
