"Due to the September quarter's record performance, YTD (year to date) value of India-targeted M&A activity (USD 46 billion) has already exceeded any annual value on Mergermarket record through a total of 281 deals," Mergermarket said in a report.
Telecommunications was the India's most active sector this year in respect of deal value. Its five deals worth USD 16.1 billion announced during January-September accounted for more than one-third of the total deal value across India, the report said.
"While such mega deals are rare, such activity within the telecom sector is likely to retain," the report stated.
