The German e-commerce investor, which is offering as many as 32.9 million new shares at 35.50 euros to 42.50 euros apiece, has enough orders to cover the sale across the price range, according to terms seen by Bloomberg News. JPMorgan Chase & Co. and Scotland’s Baillie Gifford & Co. pledged to invest a total of 450 million euros, Berlin-based Rocket said yesterday.

Proceeds from Germany’s largest IPO this year will let Chief Executive Officer Oliver Samwer push Rocket deeper into emerging markets such as Latin America and Asia by mimicking successful e-commerce companies. Presenting to a roomful of Rocket executives and reporters at a Frankfurt hotel today, Samwer said online and mobile commerce have only started to gain steam since 2007 in the emerging markets its companies target.

“The fewer stores a country has, the faster e-commerce grows,” he said. “Whoever doesn’t believe that can look at the Alibaba prospectus.”

In meetings with investors, Rocket has compared its business model with that of Jack Ma’s Alibaba Group Holding Ltd. Alibaba, the Chinese e-commerce operator, surged 38 percent in its U.S. trading debut on Sept. 19 to value the company at more than $230 billion.

EHarmony, Pinterest

Brothers Marc, Oliver and Alexander Samwer got their start setting up a German version of EBay Inc. in 1999, and have since duplicated sites such as those of EHarmony Inc. and Pinterest Inc. Rocket typically starts the companies, hires staff and provides initial marketing, design and management know-how.

“The goal is to one day be a leader in the Internet field outside the U.S. and China,” Oliver Samwer said today.

Ten Rocket e-commerce startups for which shareholder Investment AB Kinnevik disclosed earnings, including Lamoda, Dafiti and Westwing, had an aggregate operating loss of 432 million euros last year on sales of 743 million euros, according to data compiled by Bloomberg. Samwer said this month that the company plans to eventually become profitable and that it targets investors seeking long-term growth.

Zalando SE, the shoe and fashion retailer that received initial funding from Rocket in 2008, is making its own trading debut next week as it seeks to raise as much as 633 million euros.

Topping Braas

Rocket’s IPO could surpass Braas Monier Building Group SA’s $640 million sale in June to become the largest in Germany this year, according to data compiled by Bloomberg. The country’s initial sales raised about $1.3 billion in the first half, less than half what they did in the same period last year, the data show.

The offer period runs from today to Oct. 7. At the midpoint of the price range and including an overallotment, the seven- year-old business controlled by Samwer and his brothers would have a market value of 6.2 billion euros, the statement shows. The company will be listed on the Frankfurt stock exchange Oct. 9.

Rocket announced a target to raise 750 million euros Sept. 10. It boosted the amount late yesterday after receiving commitments to buy 582.5 million euros of shares. Baillie Gifford plans to invest 350 million euros, while JPMorgan has pledged 100 million euros, according to the sale prospectus. Other investors are FAR Global Private Markets Ltd., Discovery Global Opportunity Master Fund, Makshaff Trading Investments Co. and Credit Suisse Group AG.

‘Exciting’ Potential

“We are committed to investing in growth companies with exciting long-term potential and building strong relationships with their management teams,” James Anderson, a partner at Baillie Gifford, said in a separate statement.

Philippine Long Distance Telephone Co. and Germany’s United Internet AG last month injected 768 million euros into Rocket. Rocket subsequently got a bigger hold on several of its investments in an deal that gave a 2.5 percent stake to Holtzbrinck Ventures GmbH.

Before the IPO, Rocket’s largest shareholder is the Samwer brothers’ Global Founders Fund with a 52.3 percent stake. Kinnevik of Sweden holds 18.1 percent, United Internet has 10.4 percent, Philippine Long Distance Telephone holds 8.4 percent, and billionaire Len Blavatnik’s Access Industries has 8.3 percent.

Berenberg Bank, JPMorgan and Morgan Stanley are arranging the share sale. Bank of America Corp.’s Merrill Lynch, Citigroup Inc. and UBS AG are joint bookrunners.
