SAN FRANCISCO (Reuters) – Facebook (FB.O: Quote, Profile, Research, Stock Buzz) is considering a stock-listing proposal put forward by the New York Stock Exchange, a source familiar with the situation told Reuters, in the wake of a disappointing initial public offering last week on the rival Nasdaq (NDAQ.O: Quote, Profile, Research, Stock Buzz) bourse.

Facebook is mulling the pitch by NYSE Euronext (NYX.N: Quote, Profile, Research, Stock Buzz), the source said without elaborating on specifics.

Facebook and the banks that took it public, including Morgan Stanley (MS.N: Quote, Profile, Research, Stock Buzz), face questions over a $16 billion IPO that culminated in a Nasdaq debut plagued by technical glitches. The debut, on May 18, was pushed back half an hour and later led to delays in order confirmations, frustrating traders.

Facebook’s shares fell more than 15 percent from their $38 IPO price to a close of $32 on Wednesday.

Analysts say the NYSE could take advantage of the botched coming-out party as it battles the tech-laden Nasdaq for high-profile IPOs.

On Wednesday, shareholders filed a lawsuit against the No. 1 social network and its lead adviser, accusing them of hiding the company’s weakened growth forecasts ahead of the IPO, which rivals General Motors (GM.N: Quote, Profile, Research, Stock Buzz) as the second-largest U.S. debut.

A Facebook spokesman declined to comment. NYSE Euronext also declined to comment, while Nasdaq representatives were not immediately available.

SAN FRANCISCO, May 22 (Reuters) – Four of Facebook’s major underwriters — Morgan Stanley, Goldman Sachs, JPMorgan and Bank of America — reduced their financial estimates for the soon-to-be-public company following the release of a revised prospectus on May 9 that noted the negative impact of mobile users on Facebook’s business.

While Facebook did not provide any specifics in its amended S-1 filing, the four underwriters reduced their earnings and revenue estimates for both the second quarter of 2012 and the full year within the next two days, according to sources.

The new estimates highlighted a continued slowdown in Facebook’s growth, with the banks forecasting 30.4 percent year-on-year 2012 revenue growth on average, instead of the 36.7 percent growth previously expected. In 2011, Facebook’s revenue grew 87.9 percent year-on-year to $3.71 billion.

The new numbers were relayed to big investors through phone calls and conference calls, according to investors. Bank of America held a conference call on May 10 with analyst Justin Post, where the underwriter revealed the lowered estimates.

Here are the detailed figures from the four banks, according to one of the investors who received the new numbers.

SAN FRANCISCO, May 21 (Reuters) – Facebook Inc’s underwhelming debut on Wall Street increases the pressure on the social networking giant to deliver stellar growth – a novel situation for Chief Executive Mark Zuckerberg, who has been clear he is more interested in building products than making money.

Facebook shares fell 11 percent on Monday, the company’s second day as a publicly traded company, due to what many analysts and investors blamed on overly aggressive pricing by Facebook’s underwriters, as well as a decision to expand the size of the offering by 25 percent.

The poor stock market performance has intensified the scrutiny of Facebook’s business, raising the bar for the company to regain Wall Street’s confidence, say some investors and analysts.

“What’s most important now to investors is top line growth,” said Michael Binger, a senior portfolio manager at Gradient Investments. “If they’re interested in seeing their stock work, they need to have a good quarter,” he said, referring to Facebook.

Falling below the offering price is damaging to investor “psyche” noted Binger, who has personally bought some shares in Facebook but whose firm does not have a position.

“People who usually would be buying are now going ‘Something is seriously going wrong here.’ Emotions and skepticism take over,” he said.

Facebook generated $3.7 billion in revenue in 2011, with net income of $1 billion – a sharp contrast to some of the money-losing Web companies such as Groupon Inc and Pandora Media Inc, that have recently gone public.

SAN FRANCISCO, May 18 (Reuters) – The historic initial public offering of Facebook Inc did not go as planned on Friday, as the social networking company’s sky-high valuation combined with trading glitches left the stock languishing near its offering price at the market close.

Facebook shares began trading late Friday morning and opened 11 percent above the $38 offering price, but after peaking at about $45 slid rapidly at the end of the day to close at $38.23. The IPO was the third-largest in U.S. history and valued eight-year-old Facebook at $104 billion.

The surprisingly weak debut of a stock that analysts had predicted would climb between 10 and 50 percent is not likely to dent the business prospects of Facebook, which boasts 900 million users and is upending business practices and social relationships around the world.

But the unexpected developments were a clear setback for Morgan Stanley, the lead underwriter on the deal, which sources said was forced to defend the $38 price level by buying shares on the open market. Many market participants said they expected the stock to remain under pressure next week.

The offering also proved an embarrassment for the NASDAQ: the opening was delayed as the exchange struggled with a huge volume of orders, and for much of the day there were long delays in order confirmation. The SEC said late Friday that it was reviewing the situation.

Social media companies and Internet companies that had hoped to benefit from a Facebook halo effect were instead dragged down Friday, with social gaming giant Zynga dropping almost 15 percent.

Analysts said Facebook may simply have over-reached in raising the IPO price range, pricing at the top of the range and increasing the size of the offering earlier in the week.

SAN FRANCISCO (Reuters) – Facebook Inc began trading on the Nasdaq on Friday, becoming the first American company to debut with a valuation above $100 billion.

The debut — marred by technical hiccups and the lack of the first-day bounce in the share price that many had expected — marks the formal ascension of the No. 1 social network to the ranks of Silicon Valley technology powerhouses.

Here are a few comments from movers and shakers in Silicon Valley:

DAN ROSENSWEIG, CEO OF TEXTBOOK-RENTALS SITE CHEGG, WHO TRIED TO BUY FACEBOOK FOR $1 BILLION WHEN HE WAS COO OF YAHOO:

“I don’t think anybody would have imagined all of this. Except maybe Mark. If you take away the valuation, those conversations with Mark were very deep about the definition of a platform.

“He just kept talking about a platform before the platform was cool. And I’m not even sure he knew what it meant.

“But he had a vision for connecting people of all kinds. There were only four million people on the platform and they were all college kids, and if you think back then, you could only connect to people at your own college. You couldn’t even connect to friends at a different college.

SAN FRANCISCO (Reuters) – Facebook Inc(FB.O: Quote, Profile, Research) shares fizzled on their first day of trade on the Nasdaq, erasing early gains of as much as 18 percent to trade close to their initial public offering price.

The stock opened 11 percent higher and rose to $45 before rapidly heading south in frenzied trade, touching its initial public offering price of $38. The No. 1 online social network raised as much as $18.4 billion in one of the biggest initial public offerings in U.S. history.

After a delay in the opening print that drove up anxiety levels among traders and onlookers outside the Nasdaq, the company’s closely watched stock began trading at $42.05, compared with an IPO price of $38.

To rapturous applause from employees, Facebook Chief Executive Mark Zuckerberg — flanked by Chief Operating Officer Sheryl Sandberg and Nasdaq Chief Executive Robert Greifeld — rang the bell to kick off trading at the company’s Silicon Valley headquarters at 6:30 a.m. Pacific time.

The 28-year-old billionaire founder hugged and high-fived Sandberg and other employees in celebration after he pressed the remote button.

The area outside Facebook’s offices at 1 Hacker Way was packed with throngs of photographers, more than 12 television trucks, and a TV news helicopter hovering overhead as the excitement reached fever pitch.

“A 15 to 20 percent pop is in the realm of possibility,” said Tim Loughran, a finance professor at the University of Notre Dame, before the start of trade.

May 18 (Reuters) – Investors are bracing for Facebook’s Wall Street debut on Friday after the pioneering online social network raised about $16 billion in one of the biggest initial public offerings in U.S. history.

To rapturous applause from employees, Facebook Chief Executive Mark Zuckerberg rang the bell to kick off trading on the Nasdaq market at the company’s Silicon Valley headquarters at 6:30 a.m. Pacific time.

Zuckerberg rang the bell, with Chief Operating Officer Sheryl Sandberg and Nasdaq Chief Executive Robert Greifeld on either side.

With a value of $104 billion, Facebook is larger than Starbucks Corp and Hewlett-Packard combined.

“A 15 to 20 percent pop is in the realm of possibility,” said Tim Loughran, a finance professor at the University of Notre Dame. “Given they already moved their IPO range up and increased the size, that’s bullish to begin with.”

Valued at $104 billion, Facebook is larger than Starbucks Corp and Hewlett-Packard combined, sparking intense speculation on how much higher its valuation will rise once shares start trading.

“A 15 to 20 percent pop is in the realm of possibility,” said Tim Loughran, a finance professor at the University of Notre Dame. “Given they already moved their IPO range up and increased the size, that’s bullish to begin with.”

Facebook priced its offering at $38 a share on Thursday, but the price could be higher when shares begin trading under the FB symbol on the Nasdaq at around 11 a.m. Eastern Time.

Some expect shares could rise 30 percent or more on Friday, despite ongoing concerns about Facebook’s long-term money-making potential. An average of Morningstar analyst estimates puts the closing price for Facebook shares tomorrow at $50.

The IPO, expected to mint more than a thousand paper millionaires at the company, has received wall-to-wall media coverage and sparked hopes of a boom in sales of everything from San Francisco Bay Area real estate to automobiles.

Facebook employees marked the event with an all-night “hackathon” at the company’s Menlo Park, California headquarters starting on Thursday evening, a tradition in which programmers work on side projects that sometimes turn into mainstream offerings.
