Nicolas Alfonsi

Associate, Paris



Nicolas Alfonsi is a senior associate in the EMEA Private Equity team of our Global Mergers & Acquisitions practice at White & Case.

Fluent in French and English, Nicolas is admitted to the bars of Paris and New York. His practice covers both complex domestic and cross-border mergers and acquisitions, as well as private equity-backed investments, on behalf of multinational clients, such as financial sponsors, listed and non-listed companies, industrials, entrepreneurs, managers, and banks.

Nicolas works on a variety of M&A matters, including in stressed or distressed contexts. He was thus part of the White & Case team representing funds of global alternative asset manager Apollo throughout their high-profile investment alongside SVP Global into Vallourec, a world leader in premium tubular solutions, up until Apollo's exit by way of a sale to ArcelorMittal for c. €1 billion in 2024. Nicolas was also part of the team advising care home provider Orpea SA on its precedent-making restructuring and the related investment of French public institution Caisse des Dépôts et Consignations. In 2021, he worked on private equity fund Amber Capital's sale of its shares in media group Lagardère to CAC 40 Vivendi.

Nicolas is moreover active in strategic M&A transactions, most recently the sale by state-owned postal service group La Poste of last-mile B2B delivery platform Stuart to private equity fund Mutares in 2023, the $1.8 billion sale by Liberty Global of UPC PL to the Iliad group in 2022, the acquisition by the private equity sponsor Piab of leading vacuum gripping solutions provider Joulin Cemma, and the representation of the Altitude Infra Group in several acquisitions. In 2021, he was seconded to the Head of Legal M&A at BNPP Personal Finance to assist on the renegotiation of a major joint-venture partnership with CAC 40 mobility provider Stellantis. Nicolas has furthermore worked on a number of landmark LBO large-cap transactions (e.g. the primary takeover by Ardian of Inovie*, alongside sovereign funds Mubadala and GIC and pension fund APG, and the takeover by Ardian of Cérelia from IK Investment Partners*).

A graduate of Harvard Law School, Nicolas was an editor at the Harvard Business Law Review and research assistant to the late Charles Fried, former United States Solicitor General. He is a member of the economic security group at the Institut Montaigne.
