ADVANT Altana has advised Onet, an international group specializing in engineering and services, on the acquisition of the cleaning, logistics and facility management activities in France of the Danish group ISS.

ADVANT Altana advised Onet on this transaction with a team comprising Gilles Gaillard and Géraldine Malfait on the corporate M&A aspects, Marie Hindré and Delphine Laget on the competition aspects, Pierre Lubet and Dany Luu on the employment aspects and Philippe de Saint Bauzel and Marie Darcq on the tax aspects.
