能源業

????麥杰克

????巴克萊資本全球投資銀行業務主管

????麥杰克來自德克薩斯，從事能源行業并購已經長達24年，期間主要供職于雷曼兄弟（Lehman）。2011年麥杰克完成了10宗并購交易，此外還協助管理了50宗交易。其中最大的買賣是哪一筆呢？那就是為2011年第二大并購交易——美國天然氣管道公司Kinder Morgan以379億美元收購競爭對手El Paso的交易提供咨詢，并為Kinder提供133億美元貸款用以完成這筆交易。正如麥杰克對《紐約時報》（New York Times）所稱，這筆貸款顯示如今巴克萊在提供“大型并購交易咨詢業務“的同時也有能力提供“高額融資”。

科技業

????弗蘭克?夸特羅尼

????投資機構Qatalyst Partners的聯合創始人兼首席執行官

????夸特羅尼在網絡泡沫時期曾幫助網景（Netscape）等公司上市，后來有幾年由于惹上了一場曠日持久的訴訟官司而沉寂了一段時間。如今他新成立的公司Qatalyst已經成為2011年科技業并購業務的熱門經紀公司。市場研究公司Dealogic的數據顯示，2011年，Qatalyst完成了8宗10億美元以上的交易，以及2宗100億美元以上的交易，即谷歌（Google）全盤收購摩托羅拉移動（Motorola Mobility）以及惠普（Hewlett-Packard）收購英國第二大軟件公司Autonomy。2011年只有高盛（Goldman Sachs）的大宗科技業并購交易量超過Qatalyst。新興公司Qatalyst Partners趕上高盛可能指日可待。

ENERGY

????Hugh "Skip" McGee III

????Head of global investment banking, Barclays Capital

????A Texan who has worked in energy M&A for 24 years, mostly at Lehman, McGee closed 10 such transactions in 2011, and he helped oversee the firm's 150 deals so far this year. His biggest coup? Advising Kinder Morgan (KMP) on its $37.9 billion acquisition of El Paso -- the second-largest deal of 2011 -- and providing Kinder with a $13.3 billion loan to help seal the deal. As McGee told the New York Times, the loan showed that Barclays now has the "big-boy checkbook" to go along with its "big-boy M&A business."

TECH

????Frank Quattrone

????Co-founder and CEO, Qatalyst Partners

????After his stint taking companies like Netscape public during the dotcom boom -- and another few years on the sidelines because of a prolonged court battle -- Quattrone's semi-eponymous new firm, Qatalyst, has become the go-to broker for tech M&A. In 2011, according to Dealogic, Qatalyst did eight deals worth more than $1 billion and two at more than $10 billion: Google's (GOOG) buyout of Motorola Mobility and Hewlett-Packard's (HPQ) purchase of Autonomy. Only Goldman Sachs (GS) did a higher volume of big tech deals in 2011. It may not be long until the upstart firm "qatches" Goldman too.
