Arendt & Medernach

Arendt & Medernach is a Luxembourg-based law firm active in international finance, corporate transactions, and regulatory advisory. Founded in the 20th century, the firm operates within the legal and financial circuits connecting Luxembourg City, Brussels, Paris, Frankfurt and Geneva, and engages with institutions across the European Union and global markets. Its practice spans cross-border mergers and acquisitions, investment funds, banking, insolvency matters and compliance, interfacing regularly with courts, regulators and multinational clients.

Introduction

Arendt & Medernach is situated in Luxembourg City near institutions such as the European Court of Justice, the European Investment Bank, the European Securities and Markets Authority and the Court of Justice of the European Union. The firm routinely advises clients from jurisdictions including France, Germany, the United Kingdom, the United States and Switzerland, interacting with entities like the Banque Centrale du Luxembourg, the Commission européenne, the European Central Bank and the International Monetary Fund. Its multidisciplinary teams collaborate with counterparts at firms in London, New York, Zurich, Milan and Madrid, and engage with corporate actors such as Société Générale, BNP Paribas, Deutsche Bank, UBS and Crédit Agricole.

History and Founding

Arendt & Medernach was established during a period of postwar European integration that included events and institutions like the Treaty of Rome, the Council of Europe and NATO enlargement. Founders were contemporaries of legal figures who practiced during the era of Jean Monnet and Robert Schuman, and the firm developed alongside the growth of Luxembourg as a financial centre associated with entities including the Luxembourg Stock Exchange, the International Court of Justice, the Organisation for Economic Co-operation and Development and the European Coal and Steel Community. Over decades the firm expanded through mergers and lateral hires, aligning with trends exemplified by pan-European firms headquartered in Amsterdam, Brussels and Paris, and engaging in work related to cross-border deals influenced by rulings from the Court of Justice of the European Union, the European Commission and national supreme courts in Germany and France.

Key Personnel and Leadership

Leadership at Arendt & Medernach has included partners and counsel who maintain relations with chambers and bar associations such as the Luxembourg Bar, the Paris Bar and the Brussels Bar. Senior figures have backgrounds involving secondments to institutions like the European Central Bank, the European Investment Bank and the International Monetary Fund, and have previously worked at global law firms with presences in London, New York and Hong Kong. The firm’s leadership liaises with corporate boards, supervisory boards and audit committees of listed companies on exchanges such as Euronext, the London Stock Exchange and the New York Stock Exchange, and collaborates with advisers from firms like PwC, KPMG, Deloitte and EY.

Services and Operations

Arendt & Medernach provides transactional and advisory services including mergers and acquisitions, private equity, capital markets, investment funds, asset management, banking and finance, tax planning, corporate governance and regulatory compliance. The firm advises on cross-border financings, securitisations, derivatives work linked to ISDA agreements, and white-collar defence in proceedings before courts such as the Tribunal d’arrondissement and the Court of Appeal in Luxembourg. It works on matters touching on legislation and directives like the Markets in Financial Instruments Directive, the Alternative Investment Fund Managers Directive, the General Data Protection Regulation and anti-money laundering directives, coordinating with supervisory authorities including the Commission de Surveillance du Secteur Financier and the European Securities and Markets Authority.

Notable Projects and Clients

The firm has acted for financial institutions and corporate groups on high-profile transactions involving sovereign wealth funds, private equity houses, and multinational corporations headquartered in cities such as London, Paris, Frankfurt and Geneva. It has advised on fund launches registered under the Undertakings for Collective Investment in Transferable Securities regime, cross-border mergers involving companies listed on Euronext and IPOs coordinated with investment banks like Goldman Sachs, Morgan Stanley and J.P. Morgan. Clients have included banking groups, asset managers, insurance undertakings and industrial conglomerates from countries such as Luxembourg, France, Germany, Switzerland and the United States, and matters have intersected with regulatory inquiries involving the European Commission, national competition authorities and tax administrations.

Corporate Structure and Financials

Arendt & Medernach operates as a partnership with offices in Luxembourg City and representative presences coordinating work across Europe. Financial reporting and metrics are aligned with industry peers in jurisdictions such as the United Kingdom and the Netherlands, and the firm benchmarks revenue and profitability against international firms operating on exchanges like Euronext and against Big Four advisory revenue streams. Its internal structure combines practice groups for corporate, finance, funds, litigation and tax, and it maintains compliance functions interfacing with regulators including the Commission de Surveillance du Secteur Financier, the European Central Bank and the Autorité des marchés financiers.

Like many major professional services firms, Arendt & Medernach has faced scrutiny over matters related to regulatory compliance, tax structuring and litigation involving corporate clients, with cases sometimes engaging national courts, appellate tribunals and administrative authorities. Disputes have intersected with enforcement actions by bodies such as the European Commission, national competition authorities, tax authorities and financial regulators, and have involved professional responsibility issues handled by bar associations in Luxembourg and other jurisdictions. The firm’s responses have included internal reviews, cooperation with investigators and procedural defences in civil and administrative proceedings before courts and tribunals across Europe.
