China CNR Corp, the world's largest train maker by sales, raised $1.2 billion in a Hong Kong share offering, with pricing coming in at the low end after a recent rally in its Shanghai-listed stock, Reuters reported over the weekend.

Bolstered by expectations of further government investment in high-speed rail networks, China CNR has seen its Shanghai shares jump 8 percent over the past two months and investors saw little reason to price them higher amid weak overall demand for new offerings.

"All the positives have been already priced in the stock," said Stuwart Chen, an analyst at Sun Hung Kai Financial in Hong Kong. "There's no new catalyst for now."

It was the biggest attempt by a Chinese company to tap the Hong Kong market since WH Group scrapped its plans to list last month, with a downturn in equity markets weighing on demand even after the pork giant cut its IPO size by two-thirds.

China CNR sold 1.82 billion new shares, equivalent to 15 percent of its enlarged share capital, at HK$5.17 ($0.67) each, after marketing the offering between HK$5.00 and HK$6.20, sources with direct knowledge of the matter said.

It will use the funds to pay down debt, buy new machinery and invest in new rail projects. The company will start trading in Hong Kong on May 22.

Growing demand for rail services in China helped the train manufacturer log a 10 percent climb in net profit to 4.22 billion yuan ($677 million) in 2013 on a 5 percent increase in revenue to 96.8 billion yuan.

China CNR ranks first in the world in sales ahead of local rival China South Locomotive and Rolling Stock Corp, also called CSR Corp, and Bombardier Transportation. But its market capitalization at $7.8 billion lags CSR's $9.9 billion.

It is controlled by state-owned China Northern Locomotive & Rolling Stock Industry (Group) Corp, also known as CNRG, whose stake is falling to about 58 percent from 72 percent before the share offering.

China CNR received commitments worth $100 million from three cornerstone investors, with Dongfeng Asset Management agreeing to buy $40 million worth of shares. Jinxi Axle Company and China National Machinery Industry Corp, known as Sinomach, each pledged to buy $30 million worth of shares.

Cornerstone investors receive a guaranteed allocation in exchange for agreeing to retain their stakes for a set period.
