DUBAI, Nov 3 (Reuters) - U.S. investment bank Moelis and Dubai’s Emirates NBD have been hired to advise on the initial public offering (IPO) of Dubai Electricity & Water Authority (DEWA), sources familiar with the matter said. The Dubai government said on Tuesday it was planning a stock market flotation of the utility, among 10 state-backed companies to be listed as part of plans to boost activity on the local bourse. DEWA, the Dubai Media Office and Emirates NBD did not immediately respond to a Reuters request for comment. Moelis declined to comment.
