Carsten Dilling, CEO of Danish telecoms operator TDC, has disclosed that while the telco is still interested in acquiring smaller companies, its main focus remains on keeping its investment grade rating, Reuters reports. Speaking at the Morgan Stanley Technology, Media and Telecom conference in Barcelona, the executive said: ‘Our hands are full, our balance sheet is stretched right now, as we want to protect the investment grade rating … We will probably only look at small bolt-on things … over the next year or so.’ TDC’s chief executive noted that the company, which sold its Finnish business in April 2014 and bought Norwegian cableco Get AS six months later, has narrowed its footprint to the Nordic region and ruled out expansion into ‘more exotic’ markets.
