This story has been updated from its publication on May 7, 2012. NEW YORK ( TheStreet) - With the dust slowly settling after Facebook's mega-IPO, investors are starting to digest the largest-ever tech offering. The social networking giant raised just over $16 billion in its eagerly-anticipated IPO on Friday. The predicted opening day pop, however, failed to materialize, with the stock closing just slightly above the $38 offer price on the first day of trading. On Monday, the shares broke below that offer price, falling more than 10%. 2011 had its share of headline-grabbing tech IPOs, which included Zynga ( ZNGA), Renren ( RENN), Groupon ( GRPN) and LinkedIn ( LNKD) but Facebook dwarfed those deals. Facebook's offering also easily surpassed Google's ( GOOG) 2004 $1.7 billion IPO, previously the largest IPO from an American tech company. German semiconductor specialist Infineon Technologies, however, was another mega offering, raising $5.2 billion in its 2000 IPO. The chip maker ultimately opted to delist from the New York Stock Exchange in 2009. Overall, 2012 looks set to be a decent year for tech companies taking the public plunge. Prior to the Facebook offering, IPO expert Renaissance Capital said that tech firms have accounted for 20 U.S. IPOs valued at more than $50 million each this year, the most in any sector. Last year there were a total of 48 tech offerings. The IPO price of $38 a share gave Facebook a valuation of $104 billion, significantly above the market caps of tech heavyweights Dell ( DELL) and HP ( HPQ). With Facebook now a public company, we looked at the 11 largest offerings from U.S. firms, according to Dealogic.
Background: HCA Holdings ( HCA), the parent company of the Hospital Corp. of America, is a fairly new addition to the top 10 list. The health care services operator underwent an IPO in March 2011, raising $4.4 billion, after being taken private in 2006. Headquartered in Nashville, HCA operates and owns 163 hospitals and 109 freestanding surgery centers as well as diagnostic and imaging centers, radiation and oncology therapy centers, rehabilitation and physical therapy centers and other facilities, according to its profile. HCA describes itself as the nation's leading provider of healthcare services. Approximately 4% to 5% of all inpatient care delivered in the country today is provided by HCA facilities, the company says. Stock performance: Shares of HCA have fallen more than 17% since its debut as a public company last year. The stock was up 3.98% Monday to $25.61.
Background: Oil and gasoline company Conoco originally went to market in October 1998, after its previous parent, DuPont, the chemicals giant, decided to spin it off. The IPO raised $4.4 billion. Conoco merged with Phillips Petroleum in 2002. The larger energy corporation is called ConocoPhillips ( COP). Stock performance: Shares of ConocoPhillips are down 29.27% this year. The stock is up 1.42% at $51.54 Monday.
Background: Blackstone ( BX) became a public company in June 2007 when it raised $4.8 billion in its much talked-about IPO. Blackstone's IPO was controversial because it was one of the largest private equity firms to look to the public markets for capital amid a so-called frothy market that was starting to show signs of trouble and ultimately led to a global recession. As well, a bulk of the IPO proceeds went to Blackstone's founders, including co-founder and chairman and CEO Stephen Schwarzman. Blackstone had priced its IPO aggressively at $31 a share, and while the stock made strong gains during its first day of trading, the shares could not hold on to the gains, especially as the market began to crumble. Stock performance: Blackstone shares have fallen 16.27% this year. The stock is up 1.65% to $11.73 Monday.
Background: CIT Group ( CIT), the commercial finance company, underwent an initial public offering in July 2002, in which it raised $4.9 billion. But the financial crisis proved troublesome for CIT, which ultimately changed into a bank holding company so that it could accept an injection from the Troubled Asset Relief Program in late 2008. CIT ultimately declared bankruptcy in November 2009 and was also delisted from the NYSE. However, it was approved for reorganization plans a month later. Stock performance: CIT shares are down 1.2% this year. The stock gained 2.56% to $34.45 Monday.
Background: In May 2006, KKR Private Equity Investors, a publicly traded private equity fund that invests as a fund of funds, raised $5.1 billion after listing in Amsterdam. In July 2010, KKR Private Equity Investors' parent, KKR ( KKR), or Kohlberg, Kravis Roberts, delisted from the Euronext Amsterdam exchange, where it had traded since October 2009 after it acquired KKR Private Equity Investors, and began trading on the New York Stock Exchange, according to the company's 2010 annual report. KKR made a name for itself in the leveraged buyout space in the 1980s, culminating with its record breaking buyout of RJR Nabisco in 1989. It also performed the largest buyout ever of TXU in 2007. Stock performance: KKR shares have slipped 11.07% so far this year. The stock is up 2.7% to $11.40 Monday.
Background: UPS ( UPS) had one of the largest IPOs of its time. In November 1999, it raised $5.5 billion. The Atlanta-based logistics and delivery company is easily identified by its brown parcel trucks. However the company has been growing its store franchises, named The UPS Store, as well, after acquiring Mail Boxes Etc. Stock performance: UPS shares are up 1.75% this year. The stock gained 0.59% to reach $74.47 Monday.
Background: Kraft Foods ( KFT) priced at $31 a share when Philip Morris spun it off in June 2001, raising $8.7 billion and making it the fourth-largest U.S. company to IPO. Kraft Foods, based in Northfield, Ill., is one of the largest food makers in the world and the parent of popular brands including Nabisco, Oscar Mayer, Oreo and Maxwell House coffee. In January 2010, the company won a months-long bid for U.K.-based Cadbury, eventually winning the candy maker for $19 billion. The deal was completed in the spring. Last year, Kraft announced plans to split into two independent public companies -- "a high-growth global snacks business" and a "high-margin North American grocery business." The transaction is expected to be completed by the end of this year. Kraft's first-quarter earnings beat Wall Street's profit estimate by 1 cent as the company enjoyed a strong start to 2012. Stock performance: Shares of Kraft have risen 3% in 2012. The stock down 0.03% at $38.48 Monday.
Background: AT&T Wireless debuted in a public offering in April 2000, raising a whopping $10.6 billion. The IPO was meant to separate the telecom company's mobile and landline phone business one month before the dot-com bubble bursting. In 2004, AT&T Wireless was acquired by Cingular, a joint venture between SBC Communications and BellSouth. SBC also acquired the original AT&T the following year and the wireless provider was eventually folded back in. The entire conglomerate was renamed AT&T ( T). Last year, AT&T's planned acquisition of T-Mobile from Deutsche Telekom was denied by the Federal Communications Commission and Department of Justice. AT&T said publicly in December that it would end its bid for the rival. Stock performance: Shares of AT&T are up 11.18% this year, boosted by strength in its wireless business. AT&T's stock is down 0.12% to $33.62 Monday.
Background: The social networking phenomenon, which has over 900 million monthly users, filed for its IPO in early February. Morgan Stanley ( MS) was the lead underwriter for the IPO, with Goldman Sachs ( GS), Barclays Capital ( BCS), Bank of America Merrill Lynch ( BAC), J.P. Morgan ( JPM) and Allen & Company all involved. Amidst growing buzz about the offer, Facebook initially set its price range at $28 to $35 a share, subsequently hiking this to $34 to $38 a share. The Menlo Park, Calif.-based firm priced its offering at the high end of its range, for a valuation of $104 billion. Even though the widely anticipated first-day pop failed to failed to materialize, Facebook's IPO still saw the Nasdaq Exchange struggle with unusually heavy volume. The exchange resorted to manually delivering executions to brokerage houses. Robert Greifeld, the CEO of Nasdaq OMX Group Inc ( NDAQ), acknowledged technology problems related to Facebook's listing, according to a subsequent media report, saying the exchange was "humbly embarrassed" by events during the company's debut. Stock performance: After pricing its offering at $38 a share, Facebook opened at $42.05 and briefly jumped to a high of $45 before closing at $38.23. Facebook's stock was down 10.52% to $34.21 on Monday.
Background: General Motors ( GM) ended up raising $18.1 billion in its November 2010 IPO, falling just short of the top U.S.-listed IPO, according to Dealogic. GM filed for bankruptcy in June 2009 and was delisted from the New York Stock Exchange at the time. The company relisted its stock under the venerable ticker "GM" on the NYSE. Stock performance:Shares of GM have gained 6.51% this year. The stock is up 1.94% to $21.59 Monday.
Background: Visa's ( V) IPO in March 2008 was a big gamble considering that the markets had crumbled just months earlier. But despite the market forces surrounding the IPO, it was one of the most talked about and highly demanded initial public offerings in years. For context, Visa underwent the offering in a year when just 46 U.S. IPOs were completed. The Visa IPO accounted for two-thirds of the total U.S. IPO volume in 2008, according to Dealogic. Investors were eager to buy shares of the San Francisco-based electronic payments processor, particularly as it boasted double digit growth rates as Visa and its smaller rival, MasterCard ( MA) look to continue to convert consumers and businesses into using cards as payment instead of cash. Visa priced shares at $44 a share, but on its first day of trading the stock shot out of the gate at $59.50. Visa garnered a record-breaking $19.65 billion in the IPO, when all was said and done. Stock performance: Shares of Visa have gained 13.78% this year. The stock is up 2.56% to $115.52 Monday. -- Written by James Rogers and Laurie Kulikowski in New York.
