With its agreement to buy Atos Medical Inc., Coloplast A/S is consolidating its position as a global leader in the chronic care market. Founded in Sweden in 1986, Atos Medical is the largest player for laryngectomy devices, holding a market share of more than 80%. It’s a bold move from the Humlebaek, Denmark-based company as it offers to pay $2.5 billion to acquire the Nottingham, U.K-based company from private equity firm Pai Partners.
