The total payout for Patni was Rs 820 crore (Rs 8.2 billion), of which the three Patni brothers were expected to have received a Rs 377-crore (Rs 3.77 billion) windfall.
Acquiring Patni fits into NTT's strategy of increasing its offshore presence. This is why it is still pursuing a deal, say analysts, despite the now-on, now-off status of a Patni selloff for over two-and-a-half years.
When contacted, Patni's spokesperson said: "Patni doe-sn't comment on market speculation as a matter of company policy."
An email sent to NTT did not elicit any response.
NTT has been on an acquisition drive to increase its footprint in India.
It recently acquired Intelligroup of the US, which gave the Japanese firm a sizeable India presence, with almost 2,000 employees. Shortly thereafter, NTT acquired Boston-based Keane International.
The company employs 12,500 professionals, with a significant proportion of them at large centres in Bangalore and Chennai.
In an earlier interview with Business Standard, Takashi Enomoto, chief risk, sales & marketing officer of NTT Data, had said: "The group has 35,000 people.
"Of this, only 5,000 constitute our global headcount -- that, also, after the acquisition of Intelligroup."
"Though we have 2,000 people (Intelligroup) in India now, it is still too small for us to compete with big IT companies. We should have at least 10,000 offshore resources in India for us to be considered a global player," he added.
Over the next 18 months, the Indian IT services industry will see a significant pick-up in mergers & acquisitions, says Gartner.
This will be driven by both outbound and inbound demand.
"We have seen that M&A activity post-recession has accelerated. This is driven by both global firms looking at acquiring Indian firms to create an India footprint and Indian IT firms aspiring to enter Europe," said Partha Iyengar, vice-president & distinguished analyst at Gartner.
"The second push is coming from Japanese firms. Japanese players have been using China as a delivery centre for the last five to six years. But now, they need to diversify.
For English-speaking capability, India is the logical centre. Moreover, they need access to large talent pools. Logically, India fits into the plan," he added.
