Colliers, the global professional services and investment management group, has agreed to acquire Ayesa Engineering, the engineering arm of Spain’s Ayesa Group, in a deal valued at approximately US$700 million.
The transaction will see Colliers buy Ayesa Engineering S.A.U., a Seville headquartered multidisciplinary engineering and project management consultancy with operations across Europe, Latin America, the Middle East, South Asia and Australia.
Ayesa Engineering employs more than 3,200 people across 21 countries and provides services in engineering design, site supervision and project management. Its work spans transportation, water, buildings, cities, and energy. The company generated about $370 million in gross revenues in 2025.
Following completion of the deal, expected in the second quarter of 2026, Colliers’ engineering arm will operate in 23 countries with nearly 14,000 professionals. The combined business will deliver services across property and buildings, infrastructure and transportation, water and environmental markets. Ayesa Engineering will continue to operate under its existing brand, and its current leadership team will retain an equity stake under Colliers’ partnership model.
Jay Hennick, global chairman and chief executive of Colliers, said, “Our acquisition of Ayesa marks the latest pivotal step in our 30-year track record of creating shareholder value. This strategic move expands our global presence in the high-growth engineering and project management sector, strengthens our position among the world’s top 30 engineering firms, and brings more scale and opportunities to our clients and professionals worldwide. Ayesa’s culture of service excellence and innovation aligns perfectly with Colliers, setting the stage for continued growth and value creation for our shareholders.”
Colliers’ chief investment officer, Elias Mulamoottil, said: “Ayesa Engineering presents a rare opportunity to partner with a scalable international platform, offering top-tier capabilities across critical infrastructure sectors with minimal overlap to our existing operations,” he said. “Expertise in large-scale, complex projects and the ability to provide end-to-end technical consulting not only makes Ayesa a trusted global advisor, but a company that’s primed for growth. We see strong growth potential in existing and new markets, with opportunities to leverage their expertise in the U.S., Canada, and Australia as industry tailwinds drive robust demand for our services.”
Ayesa Engineering was founded in 1966 and forms part of Ayesa Group, which is controlled by its founding family. José Luis Manzanares Abásolo, chief executive of Ayesa Group, said, “As Ayesa Group’s founding family, we are very proud of the company’s nearly 60-year history of delivering world-class engineering and project management for major infrastructure projects. Colliers is the natural partner for Ayesa Engineering given their belief in our strategy and people, and the respect they have shown for our history in Spain and Seville – reflected in their commitment to preserving Ayesa’s presence in the region.”
Under the agreement, Rosalío Alonso, currently chief operating officer of Ayesa Group, will become chief executive of Ayesa Engineering when the transaction closes. He said, “Joining Colliers enables us to build on our legacy of innovation and service excellence, expand our offerings to clients, and create new opportunities for our professionals. Our team is excited to continue to grow our business as long-term partners for many years to come.”
