The big picture: Even though Facebook’s official valuation has slid from $15 billion–November 2007, when Microsoft (MSFT) invested–to $10 billion, Zuckerberg is OK with that, arguing that 1) that deal was done at the peak of the market and 2) the pact was never really a financial deal, but a way for Microsoft to partner up with Facebook–and, though he didn’t say it, to box out Google (GOOG). That sounds pretty reasonable.

Zuckerberg’s main talking points were that his company didn’t need the money, but it sure was nice to have, both to fund growth and make any M&A easier to pull off. And when it came to his new partners, he argued that DST’s existing portfolio, which includes several other social networks, would provide models/examples for his company as it continued to expand outside the U.S.

Earlier:

Facebook and its newest investors Digital Sky Technologies, are holding a teleconference to discuss the $200 million at 10 billion valuation deal the two parties just announced. I’ll be covering the call live.

Call starting “momentarily.”

On the call: Facebook Mark Zuckerberg, DST CEO Yuri Milner. Also, via phone (from D7!): Facebook COO Sheryl Sandberg and DST’s Alexander Tamas.

Zuckerberg reading statement that more or less tracks press release: “Advertising product” improving, “our business is doing really well” and we’re on track to create a “nice” business, and that’s why investors want in. DST approached us, has interesting profile and experience and insight into social networks. “We found their thinking and their leadership to be really impressive.”

Money provides “cash buffer” to support our continued growth, also possible other moves. No specific plans to talk about “but nice to have flexibility.”

Milner: “I realize not all the participants on the call are familiar with us.” Goes over DST portfolio. “We have now started to actively expand abroad.” We’re a holding company, have raised and invested more than $1 billion since 2005. Rattling off portfolio companies now.

Q&A:

What does this mean for possible IPO? Zuckerberg: “Our approach to financing has really been that we want to take money and work with partners”…”for a lot of start-ups, you get the feeling that the IPO is really the end goal…that’s not the case for us…we’re not rushing toward it…that’s really all I have to say about that today.”

What’s valuation for common stock? Zuckerberg: No comment. “There are different transactions that we’ve structured differently…we hope that there will be different things in the future…probably sometime in the next few months.”

What does this say about Microsoft’s $15 billion valuation? Zuckerberg: We did that deal at the peak of the market. That was part of a broader relationship. That investment was just one piece of it. This is also a relationship that we’re forming with DST…we hope we will work with other things over time.

“We feel really good about the progress we made…we feel this is  a good and fair valuation for us.” The Microsoft deal was at peak of market and was a strategic deal. “The world was in a pretty different place at that time.”

The international audience is 70 percent of our users. How do you monetize that? Zuckerberg: I have a few things to say, but want Yuri to talk, too. Milner: We have invested in five social networks in Europe. They have been able to monetize better than Facebook because they’re further along the curve than Facebook, which is a global company. But we think that Facebook will improve. Money will come from micropayments and advertising.

Zuckerberg: We can do advertising and have been experimenting with payments. Social networks in DST’s portfolio all monetize in different ways. Each is doing well, with a different model. We’re still growing. Online and direct advertising are growing the quickest, but over time, we expect to be able to build out a large number of these things.

What is your ad revenue going to be? Zuckerberg: A couple of months ago, we felt that everyone outside the company was underestimating our performance. We’ve been EBITDA-profitable for five straight quarters coming on six. Revenue growth has been 70 percent. Cash-flow positive sometime in 2010. That’s important because it means this investment is pure buffer. I realize those aren’t absolute numbers, but those are the ones we’re talking about.

Will DST be involved in management? Milner: We have our own businesses to run. We’ll keep in touch.

Questions about micropayments. Zuckerberg: We’ve tested a lot of things. It’s not a big part of our business, could be greater one day. They create a lot of value for users, and there are ways to monetize them. I’m looking forward to learning how these models are working.

Please talk about common stock/employee stock purchase plans. Zuckerberg: Going back to first question re. IPO. We want to make sure that we can continually make it so employees can be focused on the long term. We felt that if we let people have a little bit of liquidity, it can take some of the pressure off and let people focus on making company as good as it could be. We started to do this last year and had to hold off. Now we hope to be able to do it again.

Will that be the only way you are allowing employees or ex-employees to sell shares? Zuckerberg: Still talking about.

Is current Facebook ad business to be the main business going forward? Doesn’t mean it will be main business in the long term. You guys know everything that we’re talking about now.

Why aren’t you running big brand ad campaigns? We’re very interested in it. We have a big ad sales team. Building out offices internationally: U.K., France, a few more coming up. We think the best way to serve advertisers is to create ads that people interact with, that are “social and engaging.” I don’t want anyone to think that this isn’t a big part of our business, because it is.

Sandberg: Heavily engaged with brands. Ads specifically designed for Facebook, so they look different and behave differently than other ads on other sites, and that’s a good thing.

Preferred shares–are these are substantially similar to the ones Microsoft bought? Zuckberg: “I’m gonna duck that one.”

Does the company have any debt? Zuckerberg: [pause] There’s been some information that’s been public about debt we have for operating equipment. Beyond that, we do equity deals.

Will you do other investment deals? How many did you look at? Zuckerberg: He doesn’t really answer this question; instead he goes on to praise DST. Milner: We see things that other people don’t see, which is monetization that other social networks have been able to do. So we “kind of feel comfortable with that valuation.”

Is this largest foreign investment in Facebook? Zuckerberg: Um… [pause]. There’s been some public information about other folks we’ve worked with, but I think from reading some of the records you can get the answer to your question.

Other new deals? Zuckerberg: It was really at our option to find someone we were comfortable with. We didn’t feel like we needed to take an investment, and now we feel like we have the buffer we want.

Working on video chat product? More international products? Zuckerberg Yes. There are lots of things like that that we’re working on now. We want the site to be available in every country. We’re not translating the site. Users translate the site themselves. And a lot of the features are universally applicable.

Call finished.

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.

All of that, hopefully, would convince investors that the meandering media conglomerate had a plan, momentum, etc. And then they would finally lift Time Warner (TWX) shares out of the high teens, where they had been mired for many years.

But now an AOL-Yahoo (YHOO) deal seems stuck in neutral, the rest of the Time Warner empire is in cost-cutting mode, and a stock price in the high teens must look pretty good to investors, whose stock is currently worth about $9 a share.

Hence, a proposed 1-2 or 1-3 stock split, which Time Warner management wants shareholders to approve next month. From the SEC filing: “The Board of Directors believes that effecting a reverse stock split, resulting in fewer shares of the Time Warner Common Stock being outstanding, is likely to increase the market price and improve the marketability and liquidity of the Time Warner Common Stock.”
