Global M&A, the network of mid-market boutique investment banks, has brought in a Spanish partner in a move that plugs the final gap in its coverage since it lost a founding member to a rival group last year.

Socios Financieros, a Madrid-based corporate finance boutique, has joined Global M&A. It replaces NC Finanzas Corporativas, which quit the network along with founding member Livingstone Guarantee last April to form a three-way merger with US boutique Oneworldwide.
