Two-wheeler electric vehicle (EV) maker Ather Energy shares surged 8% during the trading session on Friday, August 28, as investors focused on a ₹1,758 crore stake transaction during the morning block deal window on NSE, and Hero MotoCorp’s move to purchase additional shares of the company.

As per the exchange filing, Hero MotoCorp, a promoter entity in the EV maker, announced after market hours on Thursday that the company’s board of directors, in its meeting, has approved the decision to purchase additional equity shares of Ather Energy from an existing shareholder.

Why are Ather Energy shares rising today?

Ather Energy shares were rising on Friday’s market as investors were reacting primarily to the latest update from promoter company, Hero MotoCorp, increasing its stake in Ather Energy.

Investors were also trading against the backdrop of a ₹1,758 crore block deal transaction which was carried out on August 28.
