ORS has announced that Erisbeg, an Irish-owned investment firm, has acquired a majority stake in the company to support the next phase of its development. ORS, an Irish multidisciplinary building consultancy and headquartered in Mullingar, Co Westmeath, will hire more than 150 new positions nationwide over the next three years, it said.

Established in 1991 by Paul O'Reilly and Finbarr Stuart and led by John Brennan, ORS, which is an Engineers Ireland corporate sponsor, has expanded significantly in recent years. Brennan and the board of directors will continue to lead the business over the next phase of its development. The expansion will include a new office base in Cork in addition to its office locations spread across the country.

John Brennan, ORS partner and MD, said: "We are truly excited about partnering with the Erisbeg team. At ORS, our culture is at the core of everything we do. Finding a partner that valued this approach was very important to us. We look forward to working with the Erisbeg team on the next phase of our expansion."

Core values shared

Finbarr Stuart, ORS partner, said: "From our initial discussions with Erisbeg, it was evident that they shared our core values and vision to take ORS to the next stage of growth and development. We are fortunate to have a skilled and vibrant workforce with the ability and ambition to drive the company towards new and exciting horizons."

Andrew Murphy, an Erisbeg partner, said: "From the first time we were introduced to ORS and its management, we were struck by the quality of the business. Fundamentally the strength of the management team and the depth of engineering expertise across the business was striking and gives us great confidence in the ability of ORS to deliver strong growth both organically and through acquisition."
