HONG KONG (Reuters/IFR) - China's Xiaomi Corp 1810.HK priced its Hong Kong initial public offering (IPO) at the bottom of an indicative range, raising $4.72 billion in the world's biggest tech float in four years, people close to the transaction said on Friday.

That values the firm at about $54 billion, almost half the valuation industry insiders touted at the beginning of the year.

The pricing comes at a delicate time for Hong Kong’s stock market, with the benchmark Hang Seng index falling 6.5 percent this month and 4.8 percent this year as investors fret over escalating trade tension between the United States and China.

As such, Xiaomi’s share sale is widely seen as a test of market sentiment for what is expected to be a packed second-half of the year for Hong Kong IPOs, with offerings including online food delivery-to-ticketing services platform Meituan Dianping.

China Tower, the world’s largest mobile mast operator, has won approval for a Hong Kong IPO that could raise up to $10 billion. However, its listing timing will depend somewhat on how well Xiaomi’s deal is received, sources have told Reuters.

“Xiaomi’s pricing won’t be good news for market sentiment,” said Hong Hao, chief strategist at BOCOM International. “But other IPO candidates will still flock to the market to list before market conditions become more challenging.”

Xiaomi is selling about 2.18 billion shares at HK$17 each ($2.17), the bottom of a price range of HK$17 to HK$22, two of the people said. That makes the IPO the largest in the technology sector since Alibaba Group Holding Ltd BABA.N raised $25 billion in New York in 2014.

Xiaomi declined to comment. The people declined to be identified as the information was not public.

The HK$17 price represents a multiple of 39.6 times 2018 earnings and 22.7 times Xiaomi's 2019 earnings forecast by its underwriting syndicate. At present, rival Apple Inc AAPL.O is trading at 17 times trailing earnings and 14 times forward earnings, showed Thomson Reuters data.

“I’m not surprised at all by its pricing at the bottom,” said Hong. “It claims to be a hardware plus internet services company, but the majority of its revenues come from the smartphone business. It’s still way more expensive than Apple on a price-earnings basis.”

Xiaomi’s price values the firm at $53.9 billion before the exercise of a “greenshoe” or over-allotment option, whereby additional shares are sold depending on demand.

The valuation is far below the $100 billion touted by sources earlier this year as well as the more recent $70 billion-plus target that some analysts and investors saw as aggressive. Xiaomi was valued at $46 billion in its last fundraising in 2014. (reut.rs/2MAcScH)

Xiaomi’s IPO adds to the $6 billion of new listings so far in 2018 in Hong Kong and is set to be the first under the city’s new exchange rules permitting dual-class shares common in the tech industry in an attempt to attract tech floats.

It was initially expected to raise up to $10 billion, split between Hong Kong and mainland China, but last week shelved the mainland offering until after listing in Hong Kong. Cornerstone investors included U.S. chipmaker Qualcomm Inc QCOM.O and telecom service provider China Mobile Ltd 0941.HK.

Set up in 2010, Xiaomi doubled its smartphone shipments in 2017 to become the world’s fourth-largest maker, according to Counterpoint Research, defying a global slowdown in handset sales. It also makes internet-connected home appliances and gadgets, including scooters, air purifiers and rice cookers.

Beijing-based, Cayman-domiciled Xiaomi is due to start trading in Hong Kong on July 9.
