Kirkland & Ellis, which opened an office in Houston in 2014, did the most Texas M&A work in 2017, and Vinson & Elkins was the leading homegrown Texas firm for 2017 M&A in the Lone Star State, according to data provided by Mergermarket.

Kirkland & Ellis led two rankings of firms for Texas M&A in 2017. Kirkland topped the list of firms ranked by value of deals, with $83 billion, and also topped the list of firms ranked by number of deals, with 80. V&E was fifth among the firms for value, with a total value of $50 billion, and second for number of deals, with 68.

Most of the 20 firms ranked by value are not headquartered in Texas, although several have offices in Texas. In addition to V&E, Akin Gump Strauss Hauer & Feld and Bracewell are the Texas firms on the value ranking chart.

More Texas firms are on the chart that ranks firms by the number of deals, presumably because the statistics include Texas M&A transactions as small as $5 million and would include firms with more work for midsize companies. Following V&E on that chart are a number of Texas firms—Locke Lord, Andrews Kurth Kenyon, Baker Botts, Haynes and Boone, Akin Gump, Jackson Walker and Bracewell.

Latham & Watkins, which opened its Houston office in 2010, is third on both charts, and White & Case, which does not have a Texas office but worked on two of the largest Texas deals announced in 2017, is second on the chart that ranks firms by value of deals.
