Vancouver-based IT consultancy Sierra Systems Inc. announced Friday the acquisition of applications support maintenance service provider RIS Inc.

Calgary-based RIS said it welcomes the move and called it a natural extension for its applications services business and will help move forward its strategy in niche IT services. RIS’ President and CEO, Peter Thompson, said the acquisition will mean “even greater resources, services and opportunities” for both companies.

According to Bellevue, Wash.-based Corum Group Ltd., the merger and acquisition services company facilitating the agreement, the transaction will have virtually no overlap in geographic or client coverage. It said that both company’s service offerings are extremely complementary and will greatly benefit both client bases.
