International law firm Cohen & Gresser announced today that France Portmann Loy has joined the firm as a partner in its Paris Corporate practice, together with two associates, Pauline Thuet and Eleonore Messina. This strategic expansion reaffirms Cohen & Gresser’s commitment to delivering unparalleled legal expertise and further solidifies its position as a leading player in the corporate landscape.

France advises on a full range of corporate matters, with expertise in venture capital. She advises her clients — founders of SMEs, ETIs and start-ups, family groups, and family offices — on their growth and transformation operations (growth and venture capital, mergers and acquisitions), as well as on their internal reorganization issues. Her clients are primarily technology and impact companies, which gives her a deep knowledge of these businesses, their way of functioning, their values, and their challenges. She recently advised the majority shareholder family on the sale of control of Biose Industrie to Bpifrance and L-Gam, and advised Intact Regenerative on a major industrial investment.

“My arrival is the outcome of a fruitful meeting with partners who are a perfect match for me, both in terms of the skills we bring to the table and the structure of the firm,” said France. “The firm’s agility and international footprint is key for my clients and the support they need for their projects.”

France’s deep experience strengthens the firm’s ability to support French and international clients in mergers and acquisitions, equity financing, expansion capital, and early-stage deals. For cross-border transactions, the Paris office works closely with the New York, Washington, D.C., and London offices. Most recently, Cohen & Gresser’s Paris team was involved in the sale of La Tribune to CMA CGM and the sale of part of the Atalian group’s activities to CD&R.

France’s background contributes to the collective strength of the Paris team and seamlessly integrates with the experience of other partners in the office: Johannes Jonas, who specializes in transactional work; Muriel Goldberg-Darmon, who specializes in financial markets and financial services, both in advisory and litigation work; Angéline Duffour, who specializes in employment law; and Franck Le Mentec, who specializes in tax law.

“We are delighted to welcome France and her team, with whom we share a similar vision of the legal profession, blending technical expertise, market knowledge, and values. Their arrival fits in perfectly with the firm’s growth strategy and complements the strengths and experience of other members of the Paris team,” said Johannes Jonas, Managing Partner of the Paris office.
