Summary
Irish private equity firm Erisbeg has completed the sale of its majority stake in ORS, a multidisciplinary building consultancy based in Mullingar, to Goldenpeak. The transaction marks Erisbeg's exit from a portfolio company it has held since January 2023, representing approximately three years of ownership during which the consultancy pursued organic growth and acquisition-led expansion strategies.
Erisbeg originally acquired the majority stake in ORS in January 2023 and subsequently executed a refinancing to support the business's growth initiatives. During Erisbeg's stewardship, ORS completed two notable acquisitions to expand its construction services capabilities across the Irish market, demonstrating active portfolio management and consolidation activity within the building consultancy sector. The refinancing was advised by Clearwater, signaling structured financial engineering to fund growth activities.
Goldenpeak, the acquiring firm, has now established itself as an active consolidator in the Irish built-environment consultancy space, with this ORS stake representing its second deal in the sector as of mid-2026. Byrne Wallace Shields LLP represented Erisbeg in the sale transaction. While commercial terms of the exit were not disclosed, the deal reflects continued midmarket PE activity in the UK & Ireland region, where professional services and construction-related consultancies remain attractive consolidation targets for growth-oriented investors.
Erisbeg itself, established in 2017, positions itself as a private equity investor focused on driving internationalisation and growth in high-potential small and medium-sized enterprises. The firm was actively deploying a €110 million investment fund targeting the Irish and broader European SME market at the time of the ORS acquisition, suggesting the exit may enable capital recycling for new platform investments within its current fund cycle.
