Philippi Prietocarrizosa Ferrero DU & Uria

Tax Tier 1

Philippi Prietocarrizosa Ferrero DU & Uria has a leading presence in this field, the result of deep expertise provided by well-known tax practitioner Walker Villanueva and his team. The firm excels on all aspects of contentious and non-contentious tax matters, attracting an enviable client base which saw some impressive additions during the year, including Credit Suisse, Liberty Seguros and online-shopping company Cornershop. In terms of recent mandates, headline client Telefónica del Perú sought advice in relation to a new service, enabling the firm to showcase its cross-border tax planning capability. The 16-strong team also includes international tax specialist Dante Sanguinetti and tax litigation director Carlos Moreano; while additional names to note at associate level include Johana Timana, elevated to practice director in July 2021, and principal Milagros Pastor, both of whom are in demand for client teams on key mandates.

The tax team is highly committed to the objectives that the company sets and offers solid solutions to problems that arise. The results obtained so far with PPU are superior to those we have had with other law firms of supposedly similar standards.’

Dante Sanguinetti is a deep connoisseur in tax and general matters and in particular of our industry. He has advised us extensively in negotiations, fundamentally on the purchase of companies, always preserving our interests and minimising exposure to tax contingencies.’

It has a multi-sectoral team which know the standards of various sectors, which is beneficial for the consultancy they carry out. They always present the best possible solutions to problems.

They show a lot of empathy with their clients, they make the problems we have their own and they look for quick and innovative solutions. Walker Villanueva and Milagros Pastor are recommended.’

Corporate and M&A Tier 2

Philippi Prietocarrizosa Ferrero DU & Uria fields a high-calibre team led by practice co-heads Guillermo Ferrero who is very active in the market, and Rafael Boisset, elected firm managing partner in January 2021. Meanwhile Javier Ezeta is 'one of the most practical M&A lawyers I have worked with across the globe' according to one client. Overall, the practice has a 'commercial and practical approach and problem-solving capabilities' that are utilised across a broad range of corporate and M&A mandates, including private equity, where it has acted for several international funds in recent years. Against the backdrop of a faltering M&A market in Peru during 2020, the firm was able to scoop up some decent manates, such as acting for Ardian France in a $51.5m joint venture with Solarpack Corporación Tecnológica for the investment in two solar photovoltaic projects in Peru (Tacna Solar and Panamericana Solar). Víctor Abad and Raúl Vizcarra are principal associates worthy of mention.
