"It is not a threat...," Mr Birla told reporters here on Sunday.
It could be noted that last year Paris-based Lafarge and Switzerland-based Holcim had announced a $40 billion merger, which will make the combined entity the world's largest cement maker.
He also said there was no proposal to merge Century Textile's cement business with UltraTech Cement.
There were reports about Century Textile, owned by B K Birla, grandfather of K M Birla, spinning off its cement business and merging with UltraTech.
In the quarter ended March 31, 2015, Ultratech Cement had reported a 24 per cent dip in consolidated net profit at Rs 657.2 crore as against a net profit of Rs 864.83 crore in the corresponding quarter a year ago.
The dip in profit was on account of a penalty imposed by the Competition Commission of India (CCI) on cartelisation charges.
The company said it deposited Rs 117.55 crore on the orders of the fair trade regulator in case of alleged
cartelisation against cement manufacturers including UltraTech.
