Simplify's Take

What believers are saying

  • FI Group added €100 million revenue and 1,800 experts, lifting EPSA Innovation to €182 million.
  • Inventura and GIS International expanded EPSA’s Nordic and procurement reach in January and March 2025.
  • Energiency’s SaaS and ACXIAS partnership deepen EPSA’s digital and energy-performance cross-sell opportunities.

What critics are saying

  • FI Group carve-out exclusions and 20-country integration create execution risk through 2026.
  • Innovation financing depends on tax-credit regimes and grant budgets; rule changes crush volumes quickly.
  • Serial bolt-ons from 2025 demand constant cross-border integration; one failed deal damages EPSA’s positioning.

What makes EPSA unique

  • EPSA now leads innovation financing after FI Group’s April 29, 2025 international acquisition.
  • EPSA spans purchasing, tax credits, grants, decarbonization, and digital tools across 20 countries.
  • ISO 27001 certification on October 30, 2025 strengthens trust for enterprise procurement and data workflows.

Epsa Innovation Announces The Acquisition Of Fi Group'S International Activities And Becomes The Global Leader In Innovation Financing

EPSA, a specialist in financial, operational and environmental performance, is a major player in innovation financing in France and Europe. EPSA Innovation, with €82 million revenues in this business segment (50% in France and 50% internationally), is experiencing rapid organic growth in Spain, Germany, the United States, Brazil, Italy, Belgium, Poland and Portugal.  EPSA announces the acquisition of FI Group, a global specialist and established leader in innovation financing in Spain, Brazil and Portugal, also present in the United Kingdom, Hispanic America, Italy, Belgium, Germany and Singapore, with €100 million revenues.  This strategic acquisition marks the emergence of EPSA Innovation as a global leader in innovation financing with projected €182 million revenues in 2025, more than 1,800 experts and 19,000 customers worldwide.  EPSA is the European specialist in performance optimization with a turnover of €500 million and a global presence. With the acquisition of FI Group's international activities, EPSA is now the international leader in innovation financing. This milestone marks a significant step forward in EPSA's global growth strategy, strengthening its strategic position in Southern Europe and the Americas.  The transaction does not include F. Initiatives (the former French entity of FI Group), which was separated from the rest of the group and carved out in June 2024 due to differences in strategic and operational priorities.  FI Group and EPSA share a common vision of innovation and consulting, rooted in a strong corporate culture based on expertise, service quality, technical excellence and regulatory compliance.  This acquisition also marks an important step in the development of EPSA Innovation, the new business unit dedicated to innovation financing: Research and Innovation Tax Credits, international and national grants (innovation, CAPEX, decarbonization, etc.) and IP Box. EPSA Innovation and FI Group will consolidate their presence in key markets and explore opportunities for future expansion together.  Thanks to this merger, EPSA Innovation will be present in 20 countries, with more than 1,800 experts in innovation financing, more than 19,000 clients supported, more than 20,000 projects per year and will process more than €2.6 billion in innovation grants.  María Corominas, CEO of FI Group, declares: ‘Today’s announcement marks the culmination of a journey that began when we first considered opening up to an investor to strengthen our financial capacity, support our expansion into new markets, accelerate our digitalization and diversification strategies, and improve our management capabilities
