Aninver and ARGON Build Joint Platform for Infrastructure and PPP Advisory
Infrastructure advisory firms Aninver Development Partners and ARGON Consultores have formed a strategic alliance combining international project experience with specialist financial and PPP expertise, while leaving both businesses operationally independent.
The agreement gives the two Spanish firms greater capacity to pursue infrastructure, public-private partnership (PPP), project finance and transaction advisory assignments across Spain, Europe and international markets. Rather than creating a merged consultancy, Aninver and ARGON will retain their respective identities and teams while progressively coordinating business development, technical resources and methodologies, including joint bids for selected projects.
Complex PPP assignments routinely require economic appraisal, demand analysis, financial modelling, risk allocation, procurement support and transaction advice to work as an integrated process. World Bank guidance places these functions at the heart of preparing and tendering viable PPP projects.
For Aninver and ARGON, the alliance offers a way to broaden that capability without the disruption and integration involved in a conventional merger.
Briefing
- Aninver Development Partners and ARGON Consultores have established a strategic alliance covering infrastructure, PPPs, project finance and economic and financial advisory.
- The firms say their combined experience encompasses more than 400 project references and engagements across nearly 80 countries.
- Both businesses will retain their identities and teams rather than merge.
- Cooperation will include shared capabilities and methodologies and joint bidding for selected assignments.
- The partnership is targeting public authorities as well as infrastructure funds, institutional investors, developers and concessionaires.
Complementary Infrastructure Expertise
The commercial logic rests on two businesses that approach infrastructure advisory from different directions. Aninver has developed a substantial international consultancy operation, reporting more than 150 projects across more than 70 countries over the past decade. Its clients include governments, development finance institutions and international organisations, while its infrastructure practice covers PPP transaction advisory, feasibility analysis, financial modelling, risk analysis and project development.
ARGON brings a particularly strong economic and financial dimension. The Madrid-based independent consultancy says its team has more than 30 years of professional experience, with its infrastructure work spanning PPP structuring, economic and financial feasibility, financial models, risk assessment, value-for-money analysis and concession economics. Its published project record includes roads, ports, hospitals, public buildings and urban infrastructure in Spain and internationally.
Aninver contributes international reach and experience working with governments and development institutions, while ARGON adds a long-established Spanish presence and specialist financial and concession expertise.
The firms put their combined track record at more than 400 project references and engagements, with experience extending across nearly 80 countries. Those figures are supplied by the companies and represent combined portfolio measures rather than the scale of a single integrated organisation.
Following the PPP Project Cycle
The proposed service range runs from early planning and feasibility through PPP structuring, financial modelling, financing and transaction support. Clients are expected to include governments, developers, concessionaires, infrastructure funds and institutional investors.
That breadth follows the way PPP projects are developed. Before procurement begins, authorities may need demand and technical studies, economic assessment, environmental and social work, financial analysis, value-for-money testing, risk allocation and market sounding. Financial models are then used to test viability, affordability, revenues, costs, financing assumptions and the allocation of risk over contracts that can remain in force for decades.
ARGON’s published portfolio includes financial and feasibility analysis associated with motorway concessions in Spain, Madagascar, Ecuador and Algeria, alongside assignments involving ports, urban transport and public buildings.
Aninver brings a different geographical profile. Its infrastructure and PPP practice works across transaction planning, feasibility, procurement and implementation, with much of its international footprint built through work with public institutions and development finance organisations.
Moving Further into Private Infrastructure
The next target is a larger share of private and institutional infrastructure work.
Both firms already have substantial exposure to governments, multilateral organisations and development finance institutions. The new arrangement is explicitly intended to increase activity with infrastructure funds, institutional investors, developers, concessionaires and other private-sector clients, while expanding their presence in Spain, Europe and other developed markets.
“The combination of Aninver and ARGON brings together capabilities that are difficult to find in an independent firm: international experience, expertise in the public sector and PPPs, economic and financial structuring capabilities and transaction experience. We want to use this combination to compete more actively in Spain, Europe and other developed markets, while continuing to grow together internationally in the multilateral market,” said Jose de la Maza, CEO of Aninver Development Partners.
Large infrastructure transactions commonly draw on multidisciplinary teams rather than a single discipline. World Bank material for PPP transaction advisory describes teams incorporating financial, technical, legal and project-management expertise, with work extending from feasibility through procurement and towards financial close.
A joint platform allows smaller specialist firms to assemble more of that capability while retaining their existing structures and areas of expertise.
Collaboration Without Consolidation
For now, Aninver and ARGON have chosen cooperation rather than corporate consolidation. There is no announced acquisition, merger or separate combined company. Instead, the firms plan to increase commercial and technical coordination progressively and pursue selected opportunities together.
“For ARGON, this alliance is an opportunity to combine our decades of experience in the economic and financial aspects of infrastructure with Aninver’s international presence and business development capabilities. We share a very similar approach to advisory work: independence, technical rigor, specialization, commitment and close client relationships,” said Ignacio Aracil, CEO and Managing Partner of ARGON Consultores.
Aracil’s background includes international banking and corporate finance as well as more than three decades working in infrastructure, PPPs, feasibility studies and financial modelling.
The structure gives both firms room to test the combination project by project while accommodating other specialists where assignments require additional legal, engineering, environmental or sector-specific expertise.
Transport and mobility, energy, water, social infrastructure and urban development are among the sectors being pursued, alongside broader infrastructure finance and corporate finance work.
For clients, the eventual measure of the alliance will be less about its combined project count than its ability to turn that experience into credible multidisciplinary teams. PPP advisory sits at the intersection of engineering, public policy, economics, finance, law and procurement. The alliance will now test whether those disciplines can be assembled effectively across two independent consultancies rather than under one corporate structure.

Strategic Takeaways
- The alliance expands capability without requiring either consultancy to surrender its identity or organisational independence.
- Aninver’s international development and PPP experience complements ARGON’s concentration on infrastructure economics, financial modelling and concession structures.
- Greater emphasis on institutional investors and private infrastructure clients broadens the firms’ traditional exposure to governments and development institutions.
- Joint bidding gives both companies access to assignments that may demand a wider combination of financial, economic and transaction capabilities.
- Execution will matter more than combined portfolio statistics, particularly on complex projects requiring multidisciplinary teams across several jurisdictions.
