DST will not get a board seat or “special observer rights” in return for its money. The two companies are holding a press conference shortly, so we may be able to extract a few more details.

The $10 billion valuation is comedown from the $15 billion figure that accompanied Microsoft’s (MSFT) 2007 investment, but no one expected that figure to hold up–in large part that deal was driven by a bidding war with Google (GOOG) and not much else.

Facebook and its newest investors are conducting a conference call to discuss the deal; I’ll be covering the call live.

FACEBOOK RECEIVES INVESTMENT FROM DIGITAL SKY TECHNOLOGIES

Passive Investment Includes Stake in Preferred Stock, Common Stock and Support for Facebook’s Continued Global Growth

PALO ALTO, Calif. — May 26, 2009 — Facebook today announced that Digital Sky Technologies (DST), one of the leading internet investment groups globally with significant stakes in Eastern European and Russian internet businesses, has made a $200 million investment in Facebook in exchange for preferred stock, representing a 1.96 percent equity stake at a $10 billion valuation.

In addition, DST has indicated that it is planning to offer to purchase at least $100 million of Facebook common stock from existing common stockholders that would facilitate liquidity for current and former employees’ vested shares in the company. The details of the plan are expected to be announced to eligible participants during the summer. Consistent with Facebook’s practice with other recent investors, DST will not be represented on the Facebook board or hold special observer rights.

“This investment demonstrates Facebook’s ongoing success at creating a global network for people to share and connect,” said Facebook CEO Mark Zuckerberg. “We’ve worked hard to bring more than 200 million people — 70 percent outside of the U.S. — onto Facebook to share with friends, family and co-workers. A number of firms approached us, but DST stood out because of the global perspective they bring — backed up by the impressive growth and financial achievements of their internet investments. We’re looking forward to working with the DST team.”

“Our investment experience in other regions reveals the tremendous value social networking companies create as they redefine how people communicate and interact,” said Yuri Milner, chief executive of DST.  “By every important metric — user growth and engagement, technological innovation and financial performance — Facebook is on a similar trajectory, though on a much more global scale. We’re delighted to invest in Facebook, Mark and his management team as they make the world more open and connected.”

Based in London and Moscow, DST is a well-respected investor in a number of successful internet companies, holding significant interests in Russia and Eastern Europe, such as Mail.ru, Forticom and vKontakte.  DST’s main assets account for over 70 percent of all page views in the Russian-speaking internet and its social networks are the market leaders in more than 13 countries, addressing a combined population of more than 350 million.

DST is run by its three partners who have complementary backgrounds in operations, investments and finance: Yuri Milner, previously CEO of Mail.ru, the #1 Russian language website; Gregory Finger, previously head of the Moscow office of NCH, a multi-billion dollar hedge fund; and Alexander Tamas, previously co-head of internet and software coverage in EMEA for the Investment Banking Division of Goldman Sachs. With its advanced understanding of opportunities in technology and social media, DST is a good fit for Facebook and an insightful partner that can help unlock additional growth opportunities.

Reached for comment, Facebook spokesperson Brandee Barker offered up the boilerplate no comment: “Facebook is a private company, so as a matter of policy, we don’t typically share details about our financial plans or comment on rumor and speculation.”

But everyone else has been speculating about the value that Facebook and outside investors place on the company, and whether Facebook needs to raise any money at all.

We do know that in 2007, Microsoft (MSFT) beat out Google (GOOG) for the right to invest some $250 million in the Facebook, placing a $15 billion valuation on the company’s preferred stock. Preferred stock is typically more expensive than common stock because it gives owners the ability to recoup their money before other investors. Facebook later raised another $60 million from Hong Kong billionaire Li Ka-shing and $10 million or so from the Samwer brothers of Germany.

And various reports have suggested that employees and others who own Facebook common stock have been recently selling it on the private market for prices that value the company in the $4 billion range.

Facebook has repeatedly said that it doesn’t need additional cash to keep going and that it expects to generate $500 million in revenue this year and begin breaking even in 2010. Last year, the company felt flush enough to offer to buy Twitter for $500 million–$100 million of which would have been in cash.
