What critics are saying

  • Eight acquisitions in 2025 and Africa reshuffling strain integration and management bandwidth.
  • Egis's private-equity ownership under Tikehau, Apollo S3, ADIA, and Neuberger pushes exit pressure.
  • A failed U.S. integration after Lochner's rebrand would undermine Egis's North American growth thesis.

What makes Egis Group unique

  • Egis spans 70 countries, combining design, operations, and concessions under one platform.
  • August 2026 Lochner rebrand gives Egis 1,500-plus U.S. professionals and 70 offices.
  • 2025 acquisitions RockSol, Engeny, Peracon, and Ecometrix deepen transport, water, and energy specialization.
