美股历史上七宗最大的IPO

    德国最大的电信公司德国电信于1996年赴美上市，通过IPO筹集了130亿美元。这是本榜单上历史最悠久的IPO。该公司于2010年从纽约证券交易所退市，因其希望减少报告义务和行政成本。

    不过，在美国资本市场上仍能看到该公司的影子。德国电信旗下子公司T-Mobile US后来通过与MetroPCS公司合并，于2012年10月实现借壳上市。

    7. AT&T 无线集团：106亿美元

    Deutsche Telekom, Germany's largest phone company, raised $13 billion when it went public in the U.S. market in 1996. It is the oldest IPO to make the list. The company delisted from the NYSE in 2010 after saying it wanted to reduce its reporting obligations and administrative costs.

    However, vestiges of the company remain on the U.S. market. The company's subsidiary, T-Mobile US TMUS -1.13% , later went public by combining with MetroPCS in a reverse merger in October 2012.

    7. AT&T Wireless Group: $10.6 billion

    AT&T 无线集团于2000年通过IPO融资106亿美元。这家公司的结构随后发生变化。当时，该公司是美国标志性电信企业AT&T Corp旗下子公司，后来重组更名为Cingular Wireless，但其资产最终又重新注入母公司。到2005年，该公司再次重组改名，成为“新”AT&T。此后，该公司的资产结构至今仍基本保持不变，并沿用其历史交易代码：T。

  AT&T exists today in a form much different form than the AT&T Wireless Group that went public in 2000 to the tune of $10.6 billion. Back then, it was the wireless subsidiary of AT&T Corp., which eventually transformed into Cingular Wireless before wrapping back into its iconic telephone-company parent. The company dubbed the company's latest iteration the "new" AT&T in 2005. That version of the company still exists pretty much intact today and trades under its historic ticker symbol: T.
