Seven Generations Energy Ltd. jumped 8.9% in its trading debut after raising CA$810 million (US$724 million) from selling a 19% stake in Canada’s second-biggest IPO of the year, Bloomberg said Oct. 30.

Seven Generations, backed by Canada Pension Plan Investment Board and New York’s Ziff family, sold 45 million shares on Oct. 29 for CA$18 apiece in its initial sale, the Calgary, Alberta-based natural gas producer said. That values the company at CA$4.27 billion based on 237.4 million shares outstanding. Seven Generations began preliminary trading Oct. 30 in Toronto under the ticker “VII.”

The shares rose 8.9% to CA$19.61 at 9:33 a.m in Toronto.

Seven Generations follows Encana Corp.’s (NYSE: ECA, TO: ECA) CA$1.46 billion sale of a stake in PrairieSky Royalty Ltd. (TO: PSK, OTC: PREKF) in May, the country’s biggest in 14 years. Seven Generations’ shares were priced at the lower end of its CA$17 to CA$21 targeted range.

Teine Energy Ltd., an energy producer that planned to sell shares this fall, pushed back the timing of its IPO amid the plunge in oil, people familiar with the matter said earlier this month. The Calgary-based company is waiting to see the outcome of the Seven Generations IPO before determining its own plans, potentially pushing a sale into next year.

Royal Bank of Canada, Credit Suisse Group AG (NYSE: CS) and Peters & Co. led a group of 16 investment banks on the Seven Generations sale. The firms have the option to sell an additional 15% of the offering after the deal closes next week, which would raise total proceeds to as much as CA$931.5 million.

Pat Carlson founded Seven Generations in 2008, raising more than $300 million from investors including Arc Financial Corp., Natural Gas Partners, Kern Partners and ZBI Ventures, an investment firm controlled by the Ziff family, whose patriarch William Ziff built a publishing fortune. Canada Pension bought its initial stake in May 2012.
