Effective date: 1 July 2026: The largest law firm merger to date in the international legal markets has been completed. The major international law firm Hogan Lovells and the long-established Wall Street firm Cadwalader, Wickersham & Taft have merged to form Hogan Lovells Cadwalader. This new transatlantic heavyweight currently generates $3.6 billion in revenue and employs 3,100 attorneys across the Americas, EMEA, and APAC regions. Nothing but superlatives. Reason enough to take a closer look – especially with regard to what this mega-merger means for the German legal market and for clients of the new firm. Thomas Wegerich spoke with Dr. Detlef Haß, the German managing partner of Hogan Lovells Cadwalader.
Business Law Magazine: Why is the combination with Cadwalader the right strategic step for Hogan Lovells, and what specific global objective are you pursuing through it?
Dr. Detlef Haß: The combination is, above all, a response to the changing reality our clients face. Today, international businesses expect legal advisors who can bring together commercial, financial, regulatory, and geopolitical considerations tailored to their industries – across jurisdictions and markets.
With Cadwalader’s elite finance capabilities and Hogan Lovells’ global strength in highly regulated sectors, we are exceptionally well positioned to serve clients at the intersection of business, finance, and government, with particularly strong capabilities in New York, Charlotte, and London.
One additional point: Until recently, many people in Europe had probably never heard of Charlotte – and they would not have been alone. Yet Charlotte is the second-largest financial center in the United States after New York City.
Business Law Magazine: What does the merger mean for Germany and the German legal market? What opportunities does it create, where do you expect potential friction, and – given the merger’s strong finance focus – what roles will Frankfurt, London, and New York play in particular?
Dr. Detlef Haß: Germany is one of the firm’s key growth markets. Our Frankfurt office will become even more important through the combination with Cadwalader, serving as the link between Europe’s capital markets and the financial centers of London and New York. This transatlantic corridor will become increasingly important for our clients.
At the same time, Germany is much more than a major financial center. As Europe’s largest economy, it shapes many of the regulatory and industrial developments that directly affect international businesses. Particularly in a more challenging geopolitical environment, demand is growing for advice that combines a global perspective with a deep understanding of the European legal and regulatory framework in the respective industry. That is precisely what our German practice as part of our European team is built to provide – and we are now able to make these capabilities available to our new clients as well. They will benefit from our experience across highly regulated sectors, including automotive, chemicals, defense, life sciences and healthcare, energy, and technology.
Most importantly, our new colleagues share our philosophy of client service. We have a common approach to advising clients. That shared mindset was central to bringing the two firms together.
Business Law Magazine: From the client’s perspective, what is the real value-added of this merger, and why is the combination of the two firms more than simply a matter of greater scale?
Dr. Detlef Haß: The international legal market is consolidating – not for the sake of size itself, but because client expectations have fundamentally changed. Across every sector, our clients want teams that take ownership and can manage complex matters seamlessly across borders, practice areas, and sectors. That is where the real value of our combination lies.
Hogan Lovells Cadwalader brings together market-leading capabilities in corporate, finance, regulatory, and disputes. Combining Hogan Lovells’ global platform with Cadwalader’s outstanding finance expertise enables us to support clients on their most sophisticated matters across all sectors throughout the G20 economies.
For our clients in Germany, this creates immediate value. They will continue to benefit from a strong full-service practice on the ground while gaining direct access to one of the world’s most highly regarded finance teams across London, the United States, Frankfurt, Paris, and Singapore. This close integration significantly strengthens our capabilities, particularly in transactions involving financial institutions, insurers, and private capital and private debt investors.
Business Law Magazine: What additional mandates or client segments do you expect the new platform to attract that Hogan Lovells or Cadwalader would not previously have been able to serve in the same way?
Dr. Detlef Haß: The most exciting mandates today emerge where several developments converge at the same time. Companies are no longer looking for specialists who solve isolated problems. They are looking for advisers who recognize the bigger picture and bring together different perspectives.
Cadwalader contributes an outstanding finance practice, while Hogan Lovells brings a globally leading position in highly regulated industries. Together, we have created a platform capable of supporting complex mandates across regulated sectors throughout the entire value chain.
At the same time, another external force is reshaping the market: Artificial intelligence is transforming the business models of our clients, creating entirely new legal challenges – and potentially many more of them. Questions around governance, data, intellectual property, product liability, and strategic decision-making are becoming increasingly important. At the same time, AI is reducing the cost of many well-established legal tasks that have traditionally been available only at the premium end of the legal market. High-quality legal advice will become more accessible because the financial threshold for engaging legal advisers will be significantly lower. Meeting these demands requires interdisciplinary teams that combine legal, technological, and commercial expertise, and can support clients in real time across jurisdictions. Through this combination, together with widely adopted standard AI solutions and our technology platform ELTEMATE for more specific use cases, we are uniquely positioned to help clients navigate this rapidly growing market.
Business Law Magazine: You have described the new firm as an “integrated transatlantic model with partners from both firms”. What will the compensation and governance model look like in practice?
Dr. Detlef Haß: The key point is that we are not forming an alliance. From Day One, we have come together as a single firm with integrated governance and compensation, designed to encourage collaboration across the firm. Our leadership brings together partners from both legacy firms, reflecting our fully integrated transatlantic model and collaborative culture.
Our governance and compensation model is designed to ensure that teams are assembled to best serve our clients’ needs. That is particularly important for international matters, where clients expect us to bring together the best possible team worldwide to address their specific challenges.
We already have extensive experience with this model. Hogan Lovells itself was created through a transatlantic merger, and we know that successful integration requires much more than a common organizational structure. It depends on shared objectives and, above all, a shared culture.
Business Law Magazine: How do you position Hogan Lovells Cadwalader within the current wave of large law firm mergers? What makes this combination unique?
Dr. Detlef Haß: Clients now benefit from an integrated global platform spanning finance, corporate, regulatory, and disputes, enabling us to support their most complex matters wherever business, finance and government intersect.
Our strength lies in balance. We combine leading expertise across practices and sectors with a strong presence across the G20 economies. That makes us resilient. We are not dependent on individual market cycles but are able to support clients throughout every stage of their business, across every sector, in both challenging and favorable market conditions.
I therefore believe that the firms which will succeed in the future are those that offer the greatest strategic relevance to their clients through an integrated approach – or perhaps more importantly, through a shared philosophy of client service. Governance will become increasingly important.
Business Law Magazine: What do you see as the biggest integration risks over the first twelve to twenty-four months – cultural, organizational, or commercial – and how will you measure the success of the merger?
Dr. Detlef Haß: The true success of the merger will not be reflected in organizational charts but in the mindset of our lawyers and our many business services professionals. Are our partners collaborating naturally? Are new mandates emerging because different teams are combining their strengths? Are we developing ideas that neither firm would have created on its own? One of the biggest confirmations throughout this process has been just how well our cultures fit together. We share the same commitment to collaboration, excellence, client service, and investing in our people.
A second measure will be our ability to innovate. AI has become the new copilot and is already changing the way legal work is performed. The key question is not whether law firms will embrace AI – they all will. The real differentiator will be which firms fundamentally rethink the way they work and continue to build the new capabilities needed to succeed. We expect to open new service products and new business lines in that journey.
A third measure will be whether we can attract and retain the very best talent over the long term. Competition for outstanding lawyers has long since become global. The most attractive employers will be those that offer international mandates, a strong culture and the opportunity to help shape technological transformation.
Business Law Magazine: Looking into the crystal ball: Where do you see Hogan Lovells Cadwalader in two years’ time – and in five?
Dr. Detlef Haß: The pace of change in our market has become so rapid that even two years is now a long-term horizon. Looking ahead is therefore both difficult and especially exciting.
Within two years, no one should still be talking about the merger. By then, it should simply be the way we operate. Today, we are one of the world’s top five elite law firms, bringing together the distinctive strengths and traditions of both firms while enabling clients to receive advice at the intersection of business, finance, and government across the G20 economies. Within two years, we will demonstrate that through the projects we deliver for our clients. Building on that foundation, and by fully embracing the opportunities created by AI, we expect to achieve exceptional growth.
At the same time, I hope that AI will have become as natural a part of everyday work for our teams as laptops and legal databases have been for many years: Tools that enable better ideas and create more time for strategic advice. We have invested consistently in innovation for years, allocating around five percent of our annual revenue to that effort. Through ELTEMATE, we have built one of the world’s largest legal technology platforms within a global law firm over the past five years.
For clients in highly regulated industries, this is a decisive advantage. They need not only standard solutions for standard problems but also AI tools that combine confidentiality, regulatory compliance, and premium legal expertise.
Five years from now, our business model will have evolved significantly. AI will have taken over much of the routine work. As a result, the value of legal advice will increasingly lie in analytical capability, creativity, and commercial judgment. We intend to help shape that future together with our clients.
Business Law Magazine: Dr. Haß, thank you very much for providing our readers with these in-depth insights. We will continue to follow the development of Hogan Lovells Cadwalader – and the discernible trend toward transatlantic mergers among the top firms in the legal markets.
