Financial and corporate

Founded in El Salvador, Arias has since expanded and added locations throughout Central America. The firm currently has offices in Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama. Ana Teresa Rizo is the managing partner of the firm’s Nicaraguan office, located in Managua. The firm is a member of IBA, World Law Group and PRAC. The firm works across the financial and corporate and project development practice areas. It represents both strategic buyers and sellers in acquisition matters, as well as lenders in banking matters including credit facilities, loan agreements and project financing. The team has experience working across a variety of industries.    
 
 

Highlights  

The firm’s corporate department worked on transactions that required the approval of the antitrust authority. One  example is the firm’s representation of Grupo Bimbo as the seller in a significant sized acquisition of the client’s confectionary business called Ricolino, to Mondelez. This was a unique cross-border deal because it was governed by Mexican law but still had to comply with Nicaraguan authorities.  

The firm was active in finance, advising Banco Santander as lender in a cross-border loan granted to RANSA CORPORATION. This was a complex acquisition financing that involved several stakeholders and jurisdictions. 

 

Key clients  

The International Finance Corporation, Grupo Bimbo and Banco Santander

“Expertise and good quality communication. Whenever you need an answer, they provide.” (Banking client) 

“There is an Escrow fund pending for the next five years and Arias Law Nicaragua has been very diligent in negotiations for amendments in our benefit.” (M&A client)
