HCL Technologies on Tuesday surged as much as 12 percent a day after the country's fifth largest IT software and services provider announced the completion of the 441 million pound acquisition of the UK-based SAP consulting company Axon Group Plc.

On the National Stock Exchange, shares of HCL Technologies opened at Rs 107 and rallied further to witness the day's high of Rs 116, up 11.70 percent from the previous close.

Similarly, on the Bombay Stock Exchange, the software major opened at Rs 112.50 and gained further momentum to touch a high of Rs 116, a jump of over 11.32 percent from its last closing.

HCL on Monday completed the country's biggest overseas acquisition in IT space after a UK court cleared the deal last week.

Post-acquisition, HCL Axon would be headed by Steve Cardell, the President of Axon and the new entity would pursue deals worth 1.2 billion dollars.

"The current quarter is going to be the biggest quarter for us in terms of contract value. The funnel size - deals to be persuaded for HCL Axon - is 1.2 billion dollar," HCL Technologies CEO Vineet Nayar had said.

The independent entity would have 4,500 consultants which includes 1,700 people involved in the SAP practice in HCL. In its race to acquire the UK-based firm, HCL had elbowed out Infosys Technologies by making a counter-bid and raising the offer by 8.3 percent.

HCL Technologies had made an offer of 650 pence a share, compared with Infosys' offer of 600 pence, valuing Axon at 441.1 million pound.
