Nexi SpA is already hunting for its next target after agreeing a milestone payments merger with Italian rival SIA SpA, as consolidation in the sector shows little sign of easing. Milan-based Nexi has made a non-binding offer for Denmark-based Nets A/S, according to people familiar with the matter, who asked not to be identified because the information is private. Nets's private-equity owners invited a select group of potential buyers to submit offers and could enter advanced talks with a preferred bidder as soon as this month, one of the people said. If Nexi were to buy Nets, it would extend its reach as a pan-European payments giant with operations spanning Italy, German-speaking countries and the Nordics. News of its approach follows its agreement to buy SIA for 4.56 billion euros ($5.3 billion) to create one of Europe's biggest payment providers.
