What you do matters to us

Our mission

We strive to offer our clients tailor-made legal solutions that correspond to our clients’ specific economic needs.

We have long-standing experience in fundraising, corporate-M&A transactions and private debt structuring and restructuring. We are involved in a wide range of market transactions that raise technical and strategic regulatory issues, on both the equity and debt sides, involving long and short positions.

We combine our technical expertise in business law with an in-depth understanding of the rule of law from an economic point of view, the financial and accounting aspects of our cases and the institutional and political issues at stake. This holistic approach allows us, beyond our legal expertise, to put forth holistic strategies leading to the improvement of existing practices and interpretation of the law, and TO understand the full context and issues at stake in the cases we handle.

We share our clients’ convictions. Working with them both means defending their interests to the best of our ability and giving a sense to our profession.

The firm

In 2017, Sophie created Vermeille & Co with the belief that investors’ rights were insufficiently protected, and that the Paris financial center lacked a law firm dedicated to the protection of these rights.
We intervene on legal and financial issues that often involve complex strategic aspects.
Our clients are companies and investors investing in and/or structuring equity, debt, hybrid and structured financings.
From financial regulation to litigation and governance, we have a wide range of legal skills which we complement with our economic and financial understanding of the rule of law.
We regularly cooperate with colleagues from other law firms to provide our clients with comprehensive legal advice, including in areas of the law outside of our main fields of expertise, such as competition law and tax law.
We frequently interact with journalists from reputable French newspapers, which allows us to keep up to date of the latest news and market rumors and to intervene in the press on mediatic cases.
Our values align with our client's interests, enabling us to cast a consistent and credible voice to private and public institutions.
