Caiado Guerreiro assists Poke House in merger

With a team led by Jorge Ribeiro Mendonça, Caiado Guerreiro advised Poke House Italia in the merger with the Portuguese chain with the same name, Poke House Portugal, founded in late 2017 by Duarte Costa and Francisco Guedes.

Poke House Italia was advised on the Italian Law perspective by the internal legal department coordinated by Giulia Bergamasco and on the Portuguese Law perspective it was advised by Caiado Guerreiro through the team led by Jorge Ribeiro Mendonça and supported by Rui Figueiredo Marcos, lawyer, and Neuza Felizardo Carreira, trainee lawyer.

Through the recently announced operation, Poke House Portugal will receive a part of the five million euro investment raised by the chain with the same name in the Italian market. The merger between the two companies gave rise to the fifth «Poke» restaurant (a Hawaiian dish with a Californian soul) in the Lisbon district, at the Colombo Shopping Centre.

The Poke House chain has opened four restaurants in Portugal in three years (Chiado, Strada Outlet, Atrium Saldanha and CascaiShopping) and has the medium and long-term goal of opening 12 shops in Lisbon and three in Porto. Following the merger with Poke House Italy, the chain will carry out a rebranding process in Portugal and create 180 new jobs next year.

Internationally, the brand has already reached Spain and the goal is now to achieve the EMEA (Europe, Middle East and Africa) market leadership in the next two years, after completing the €5 million investment. In April 2020, Poke House Italy kicked off this €5 million investment, from the Milano Investment Partners fund managed by the Moratti family, which supports the company’s plan in its ambition to expand and add 85 new restaurants to the portfolio over the next four years. Matteo Pichi and Vittoria Zanetti founded the Poke House Italia chain at the same time as the Portuguese entrepreneurs and with the same name.

Caiado Guerreiro assists client in major Angolan privatization

Baobab Cotton Group, a client of Caiado Guerreiro, won one of the largest privatizations in Angola through a public tender, with the assistance of Caiado Guerreiro’s lawyers.
The public tender dealt with the privatization of 13 industrial units in the Special Economic Zone (ZEE) in Viana, making the country raise about $ 3.5 billion through the award of contracts. 30 companies were involved in the tender, of which the companies in the textile industry, África Têxtil (in Benguela) and Comandante Bula (Kwanza Norte), units valued at $500 million, were awarded to Baobab Cotton Group.

Caiado Guerreiro’s team, led by João Caiado Guerreiro, Sandra Jesus and Paulo Costa, was responsible for all the process related to the public tender and for all the preparation and document review involved in the transaction, in addition to the analysis and advisory work in all steps of the process. «We are very satisfied with the results obtained. It is gratifying to have Caiado Guerreiro associated to a transaction of this importance and dimension and, above all, to be able to deliver to our clients the results expected by them», says João Caiado Guerreiro, on behalf of the team.

This public tender follows the privatization process of Sonangol, which until now, had already 25 public tenders launched. From the two tenders already awarded, a revenue of about 23 million Euros has been generated. In the words of Osvaldo João, Secretary of State for Finance and Treasury, the Angolan government hopes that these privatizations will contribute to the revitalization of the production units and thus recover the weakened economies. According to him, the Baobab Cotton Group, based in Zimbabwe, has shown that it has the technical and financial capacity to take responsibility for the management of the two textile units, having therefore won two of the large companies that have contributed to the growth of the confectionery industry in Angola.
