PARIS, Sept 20 (Reuters) - The chief executive of French cloud computing services firm OVHcloud said on Monday it was “much too early” to talk about the valuation of the company ahead of its planned initial public offering. OVHcloud said earlier in the day that it aimed to raise 400 million euros ($469 million) by selling new shares in an initial public offering (IPO) in Paris but did not provide details on the timing of the IPO, nor on its expected valuation. The Wall Street Journal reported on Sunday the deal could value the company at more than $4.7 billion.
