Experts

Our accomplished team of economic experts has extensive experience consulting and communicating with the agencies on behalf of our clients.

Merger Review Capabilities

Our team has extensive experience with merger enforcement agencies in the United States, Europe, and other jurisdictions. Many of our merger review experts have served as agency economists, including at the Department of Justice (DOJ), the Federal Trade Commission (FTC), the Federal Communications Commission (FCC), and the European Commission (EC), among others. These experts, as well as others on our team, have substantial experience with both agency merger reviews and litigations. The agencies also frequently retain us to offer independent opinions about whether a merger raises antitrust concerns.

Our experience gives us insight into how enforcers think about economic issues in merger review and enables us to communicate credibly and effectively on behalf of merging parties. Working with our team gives our clients an advantage when planning and navigating merger review proceedings.

Before a deal comes before the agencies, we provide merging parties with assessments of antitrust risks and strategies to address potential agency concerns. Our team provides advice at the early stages of a merger, when the deal is still being structured, that can help parties avoid costly and disruptive reviews.

After a deal is announced, it is important to anticipate and understand the agency’s questions and potential concerns. Engaging with the agency on the facts and economics of how a specific industry or market operates is critical. We work with merging parties to provide relevant economic analyses and respond to agency requests, including providing analytical support for expert white papers or agency presentations and assisting with document and data production.

When the agency requires merging parties to produce data, including for compliance with a Second Request, our team supports our clients efficiently and effectively. We work with clients to generate and organize the relevant data, leveraging our experience to analyze the data while ensuring they are fully responsive to the agency’s request.

The expertise and technical capabilities of our Data Science Center allow us to quickly and effectively navigate situations with particularly large or complex data, to maximize the client’s responsiveness to the agency.

Our deep experience with mergers that proceed to litigation and, ultimately, to trial, offers our clients an advantage from the earliest stages of a transaction’s review. We leverage our expertise to help clients avoid or prepare for the possibility of litigation. When necessary, our teams are positioned to seamlessly transition to litigation.

With offices in the United States, London, and Brussels, our firm provides the expertise and capabilities to assist with multi-jurisdictional reviews. Our consulting and affiliated academic experts have advised parties in merger proceedings before enforcement bodies worldwide, including in Europe, Australia, Brazil, China, South Africa, Turkey, and other jurisdictions.

Our merger investigations team has consulted on merger reviews in a wide range of industries, including:

  • media and entertainment
  • medical devices
  • pharmaceuticals
  • retail
  • technology
  • telecommunications
  • transportation (airlines, rail)
