Madrid, 16 June 2023 – Asterion Industrial Partners, a Spanish infrastructure investment management firm in Europe with expertise in telecommunications, energy and mobility, has closed an agreement with SSG Group (Servicios Socio Sanitarios Generales) to acquire a stake in the healthcare transport company.


Asterion has extensive experience in infrastructure management, which, together with its financial capacity, will enable it to support SSG Group’s current growth plan to make the company the leader in sanitary transport in Spain. SSG Group currently operates in Spain and maintains a strong presence in the regions of Andalusia and Castile-La Mancha, an activity that Asterion will continue to promote.


SSG Group, which will maintain its headquarters in Seville, will continue to work to provide the best service to users and Public Administrations, one of the fundamental pillars of its business plan. The founder of SSG Group, Diego Prieto, will maintain a stake in the company and will stay on as a director.


The transaction is subject to the approval of the competition authorities and the fulfilment of the conditions precedent included in the agreement signed by Asterion and SSG Group.


Jesús Olmos, CEO of Asterion Industrial Partners, said that the acquisition of a stake in SSG Group has been possible because both companies share the values and strategic lines necessary to drive a business such as sanitary transport. “Asterion’s experience in the infrastructure sector and its drive to include social, environmental and good governance sustainability criteria in the companies’ business will allow SSG Group to fulfil its ambitious growth plan, while continuing to provide top quality services to users and public administrations”, he explained.


Royal Bank of Canada advised on the financial side of the acquisition and Herbert Smith Freehills on the legal side.
