HELSINKI/PARIS (Reuters) – Nokia will buy Alcatel-Lucent in an all-share deal that values its smaller French rival at 15.6 billion euros ($16.6 billion), building up its telecom equipment business to compete with market leader Ericsson. Nokia’s takeover of Alcatel-Lucent will redefine a telecom equipment sector suffering weak growth prospects and pressure from low-cost Chinese players Huawei [HWT.UL] and ZTE. The combined company will have about 114,000 employees and combined sales of around 26 billion euros.
