STOCKHOLM (Reuters) - Telecom towers have become the target of several big deals as Spain’s Cellnex and U.S.-based American Tower Corp race to increase their European footprint, eyeing the roll-out of next-generation 5G technology. Cellnex’s rapid expansion will give the company more than 100,000 tower sites in its portfolio, compared with about 82,000 towers for Vantage, which was spun out of Vodafone Group. American Tower, which has nearly 200,000 towers globally, has a quarter of that number in Europe, and about 170,000 towers are still owned by mobile network operators. Here are some of the tower-related announcements since 2020: February, 2021: Cellnex reaches agreement with Altice and Starlight Holdco to acquire Hivory, which has around 10,500 masts in France, planning an initial investment of 5.2 billion euros ($6.3 billion).

February, 2021: Orange announce the launch of its European masts company TOTEM, which will house its 25,500 towers. January, 2021: Spanish telecom company Telefonica sa it has agreed to sell its mobile phone masts in Europe and Latin America to U.S.-based telecom infrastructure operator American Towers for 7.7 billion euros in cash.
