最会赚钱的美国公司排行榜：苹果第三 谷歌仅17

15. 花旗集团（Citigroup）

财富美国五百强排名：20

2011年盈利：111亿美元

    花旗集团的盈利比上年增长4%，达到110亿美元。你完全有理由认为他们今年成绩不错，但如果回顾2006年时的花旗集团，当时的盈利是在210亿美元左右，你就知道与当时相比还是有一些差距的。

16. 伯克希尔哈撒韦公司（Berkshire Hathaway）

Citigroup

Fortune 500 rank: 20

2011 profit: $11.1 billion

    Citigroup's profits were up by 4%, to $11 billion, from the year before. It's safe to say they had a good year, but when you look back at 2006, when Citi pulled in roughly $21 billion, you realize they have some ground to cover.

Berkshire Hathaway

财富美国五百强排名：7

2011年盈利：103亿美元

    尽管伯克希尔•哈撒韦公司从去年的第10名降至今年的第16名，但2011年对他们来说依然是值得庆贺的一年。公司的所有主要业务都成绩不俗，旗下的五家最大的非保险类公司伊斯卡金属制品公司（Iscar）、路博润公司（Lubrizol）、马蒙集团（Marmon）和中美能源公司（MidAmerican Energy）都收获了破纪录的营业收益。

    然而伯克希尔•哈撒韦也并非一帆风顺。公司曾花费20亿美元投资未来能源控股公司（Energy Future Holdings）债券，最终遭受巨额损失。

    公司还有若干项曾经如日中天的业务因房地产市场波动而遭到严重影响。克莱顿房屋公司（Clayton Homes）是美国最大的房屋制造商，在去年美国房屋建设总量中只占到约7%。

17. 辉瑞制药公司（Pfizer）

财富美国五百强排名：40

2011年盈利：100亿美元

    在辉瑞公司的拳头产品降胆固醇药立普妥（Lipitor）专利到期之后，很多人都对辉瑞能否保持其全球最大制药公司的地位持怀疑态度。2011年，由于专利到期，公司承受了50亿美元的损失，但仍然排在盈利能力最强公司排名榜的第17位。

    在今年上榜的所有公司里，辉瑞公司是与2010年相比收入变化最小的，只有0.02%。然而，公司将总收益的28.7%回馈给股东，是上榜公司中股东回报率最高的公司之一。

Fortune 500 rank: 7

2011 profit: $10.3 billion

    Even though Berkshire Hathaway slipped from No. 10 in last year's most profitable list to No. 16 this year, they still had plenty to celebrate in 2011. All of the company's major businesses performed well, with each of their five largest non-insurance companies -- Iscar, Lubrizol, Marmon Group, and MidAmerican Energy -- delivering record operating earnings.

    It wasn't all smooth sailing for Berkshire Hathway, though. The company spent about $2 billion in bonds of Energy Future Holdings, which ended up as a big loss.

    It also hasn't helped that several of Berkshire's businesses are significantly influenced by fluctuations in the housing market, which has certainly seen better days. Clayton Homes, the largest producer of homes in the country, accounted for about 7% of all homes constructed in the U.S. last year.

Pfizer

Fortune 500 rank: 40

2011 profit: $10.0 billion

    After the expiration of its patent for rockstar cholesterol drug Lipitor, many wonder whether Pfizer can hold onto its status as the world's largest drug maker. The company sustained $5 billion in losses related to the patent expiration in 2011, but they still managed to land at No. 17 on our list of most profitable companies.

    Among all companies on this year's most profitable list, Pfizer experienced the smallest change in revenue from 2010, at .02%. And the company delivered a 28.7% total return to shareholders, one of the largest returns in this year's cohort.
