France > Banking and finance: transactional work Tier 2

Shearman & Sterling LLP is recognised for its work in asset and real estate finance where it undertakes several large LBOs and acquisition financings every year. Representing both domestic and international financial institutions, as well as corporates, sponsors, debt funds and investment funds, the team is routinely instructed on several high-value transactions. A good example of this is its work advising the mandated lead arrangers on the financing of the acquisition of a portfolio of 31 hypermarket and supermarket properties valued at €465m. The group's partnership has also grown in size with the promotion of project finance specialist Lachlan Poustie, who represents a number of development finance institutions and is dual qualified in England and France. Pierre-Nicolas Ferrand leads the group focusing on LBO, real estate and asset financings.

France > Capital markets: equity capital markets Tier 2

The practice at Shearman & Sterling LLP stands out due to its clear international orientation, its frequent involvement in the development of French capital market law, its dedicated employee shareholding practice under the lead of Sami Toutounji, and its broad range of expertise. Practice head Hervé Letréguilly and his team assist with IPOs (including the market's most high-profile mandates), rights offerings and hybrid securities, as well as on equity-linked transactions. A stand-out feature of the practice is its experience in advising the French state on block trades. In addition, its particularly close ties with colleagues from the London and New York office allow for smooth advice across borders.

'Ideal for advancing a deal', Shearman & Sterling LLP's industry sector strength in financial institutions, TMT, healthcare and energy, combined with its expertise across the full range of transactions, make it a comprehensive practice for clients. Matters on which the department is particularly rated include public and private M&A, acquisitions, divestitures, joint ventures and tender offers.

Guillaume Isautier is in charge, assisted by Nicolas Bombrun. Adding to the group's bench strength, Thomas Philippe was hired from Mayer Brown in October 2019.

Brilliant team, extremely responsive and business-oriented. Ideal for advancing a deal.’

Guillaume Isautier literally carries the files from start to finish. He is extremely involved in all of his files which is always very appreciable. He gets over all blockages and having him by his side around the negotiating table is a big advantage. Very good expertise in the banking sector.

Technicality, proactivity, availability, pragmatism: Shearman ticks all the boxes and, in my opinion, offers one of the best quality of service on the Parisian market.

Guillaume Isautier appropriates his clients’ projects as if they were his own, and that changes everything: he anticipates subjects perfectly, asks himself the right questions and keeps a global vision at all times.

Algeria > Foreign firms Tier 1

The Paris-based international arbitration team at Shearman & Sterling LLP is often instructed by the Algerian government in disputes. Yas Banifatemi and Benjamin Siino successfully acted for the Algerian government in a dispute against Orascom TMTI, involving an award by an international arbitral tribunal. Gaillard and Maude Lebois also successfully defended a claim against the Algerian state by a Spanish construction group. Coralie Darrigade represents companies and states in arbitrations.

Colombia > Dispute resolution > Arbitration Tier 3

With the February 2021 hire of Ricardo Alarcón -formerly an associate at Shearman & Sterling LLP‘s Paris office- as international arbitration practice director, the team at DLA Piper Martinez Beltrán has notably increased its specialization in the arbitral segment. The 11-strong team -including three partners- handles primarily commercial domestic and international arbitration as part of a broad disputes practice that also has a reputation for providing remedial advice to resolve contractual disputes through negotiation. Managing partner Camilo Martinez  is the senior figure for arbitral matters. He co-leads the disputes team with: José Miguel Mendoza (a former chief judge at the country’s specialised business court) who is a specialist in shareholder disputes; and Nicolás Polanía (also head of the office’s insolvency practice) who sits as an arbitrator at Medellín Chamber of Commerce’s arbitration centre. Recent matters include advising  clients Saur Colombia and Gestión Técnicas del Agua in ICC arbitration against Hipsitec Latam, Systems Solutions de Colombia and Inversiones H20 regarding multiple indemnity claims, as well as in proceedings against Inversiones Romero seeking the application of a material adverse effect clause; both cases were subsequently negotiated. Further associate level support comes from senior Julian Solorza, who heads up the office’s litigation practice and also handles domestic arbitration; associate practice director for civil and state responsibility, Sergio Rojas Quiñones; and seniors Juan Pablo Amaya and Sergio Londoño González, who focus on corporate disputes and governance, and corporate dispute management, respectively. Other matters include the successful representation of a major oil multinational in a conflict regarding interpretation of a partnership agreement. The team is also advising a client on the pre-trial stages of two different ICSID arbitrations against sovereign governments.

DLA Piper Colombia is trusted business partner. Sergio Rojas and Camillo Martinez are top-notch litigators. They have respected bankruptcy and commercial experience. They make time to understand our business and legal needs. I would not make any decision without first consulting with Sergio and Camillo. (We also engaged Sergio and Camillo in a complicated matter before the Superintendencia de Companias.)

Sergio is thorough, responsive and knowledgeable about Colombia law and local practice. His ability to explain complex procedures is appreciated and a most useful skill.’

Lawyers who have attended us: Jose Miguel Mendoza; Sergio Londoño – concrete solutions, identifying the associated risks. Comprehensive support in the case attended, agility and opportunity for the required responses.

It is a dynamic team, attentive to responding on time and according to our needs to all the requirements in front of the processes in which they act as our attorneys-in-fact and show extensive knowledge on the subjects under litigation.

DLA Piper Martinez Beltran, has all the qualities that one can expect from a law firm, the most important for us is the integrity, the transparency, the honesty of their work. In the same way, I highlight from DLA the sense of belonging with which they assume each case, the discipline and rigour with which they understand the details of the cases under their charge and the seniority added to the knowledge of the law with which they define forceful winning strategies, clear and precise. We respect the other firms we work with, however DLA is undoubtedly the best, they are consistent, their processes, their manners and manners demonstrate the greatness of their team of lawyers.

The people at DLA Piper Martinez Beltran are the best lawyers in the country, that is because above all, before being lawyers, they are empathetic human beings, educated in values, aware of their privileges, of the impact of their work on a country like Colombia. Camilo Martinez and Sergio Rojas Quiñones are always available and alert, always taking care of our interests, always aware of the available resources and the limits to achieve the objectives. I fully trust them, their recommendations, decisions and actions. We are certain of the correctness of their actions, of the coherence between what they say with what they think and what they represent as the best law firm in the country. We have been with them for many years and they do not disappoint us.

In DLA Martinez Beltran they have included a series of webinar-like tools, with different topics, all of great impact in the current situation, clients appreciate it since it gives us the opportunity to anticipate, prepare for and prevent situations that could have negatively impacted our business.
