Auren Reinforces Leadership in Spain with Largest-Ever Moore Integration, Adding 140 Professionals

Auren, one of Spain's leading professional services firms, has completed its largest acquisition to date by integrating Moore's operations in Madrid and Barcelona. The deal brings 140 new professionals and €13 million in annual revenue into the Auren fold, according to La Opinión de Málaga.
The move cements Auren's position at the top of Spain's audit, tax, and advisory market. It also expands the firm's reach in the country's two biggest business hubs simultaneously, reported El Periódico.
The integration of Moore in Madrid and Barcelona marks a new chapter for Auren. No previous deal by the firm has matched this scale, according to Levante-EMV. With 140 professionals joining at once, the firm adds serious capacity in two cities that together drive much of Spain's corporate activity.
The €13 million in business volume that Moore brings is not a small figure. For context, it represents a meaningful single-step jump in Auren's total revenue base. El Periódico de Aragón noted that the operation is the largest Auren has carried out to date.
The deal is structured as a full integration, not a partnership or alliance. Moore's 140-person team joins Auren directly. Their client relationships and revenue — totaling €13 million — transfer as part of the operation, according to Diario de Mallorca.
This kind of full absorption is different from looser network arrangements common in the audit sector. Auren absorbs Moore's staff, know-how, and client base in one move. La Opinión de Murcia reported the transaction covers both the Madrid and Barcelona offices together.
Spain's professional services sector is fiercely competitive. The Big Four — Deloitte, PwC, EY, and KPMG — dominate at the top. Auren has long positioned itself as the leading Spanish-owned alternative. This deal makes that claim harder to challenge, noted LNE.
Adding depth in Madrid and Barcelona is strategic. Most of Spain's largest companies are headquartered in one of those two cities. A stronger local presence means Auren can compete for bigger mandates. Diario Córdoba highlighted that the deal reinforces Auren's leadership across the national market.
Auren has grown steadily by absorbing smaller and mid-sized firms over the years. But this Moore deal sets a new benchmark. The combination of size — 140 people and €13 million — makes it stand out from past moves, according to El Periódico Mediterráneo.
The firm now heads into the next phase of growth with a larger team and a stronger footprint in Spain's core markets. Observers will watch whether Auren follows this deal with further integrations, as La Provincia noted the firm's clear appetite for expansion.
