What is the Biocon-Ampin deal about?

According to the exchange filing, Biocon has invested Rs 5.47 crore in AMPIN, picking up 54.76 lakh equity shares at a face value of Rs 10 each. Following this transaction, the company holds 59.76 lakh equity shares of AMPIN, translating to a 37.77% stake on an undiluted basis.

That stake, however, is expected to come down. Once other investors make their planned contributions into AMPIN, Biocon’s holding will be diluted to 15.91% of the company’s fully paid-up capital.

The acquisition was made through cash consideration, and the allotment of equity shares to Biocon is expected to be completed shortly, as per the filing.

Why is Biocon buying a stake in AMPIN?

Biocon said it intends to hold its equity stake in AMPIN throughout the tenure of the Power Purchase Agreement and the Share Purchase, Subscription and Shareholders Agreement signed between the two entities. 

This structure is necessary to maintain what the company calls “captive status” under the Electricity Act, meaning Biocon would be eligible to directly consume power generated by AMPIN rather than purchasing it through a grid intermediary.

The company said the acquisition supports its renewable energy objectives and its goal of procuring green energy, while also helping reduce operational energy costs.
