March 2 (Reuters)- Canada's Constellation Software Inc's quarterly profit trailed estimates, partly due to higher expenses and a foreign exchange loss.
The software maker's October-December adjusted profit rose to $23 million, or $1.09 cents a share, from $15 million, or 69 cents a share, last year.
The company, which has operations in North America, Europe and Australia, said revenue rose 30 percent to $171 million.
Analysts on average were expecting the company to earn $1.14 a share, on revenue of $165.7 million, according to Thomson Reuters I/B/E/S.
The company, which completed five acquisitions in the quarter, said organic growth was just 1 percent year-over-year.
Constellation, which makes customized software for private and public sectors entities, posted foreign exchange loss of $2.3 million, compared to $1.9 million last year.
The Toronto-based company's shares, which have gained over 10 percent in the last three months, closed at C$53.85 on Wednesday on the Toronto Stock Exchange. (Reporting by Aftab Ahmed in Bangalore; Editing by Saumyadeb Chakrabarty)
