Reuters: German TV broadcaster ProSiebenSat.1 is said to be in talks to buy a stake in advertising group Scout24 from U.S. private equity firm Hellman & Friedman, according to a report in Handelsblatt. The German business newspaper said ProSieben had two options — one to take a majority stake in Scout24, and another to acquire a minority stake combined with a guarantee by Scout24 to seek a stock market listing in October. Scout24 is planning an initial public offering (IPO) this year, Handelsblatt said.
