Energy companies made up more than a third of Texas initial public offerings in 2014.

In 2014, nine of the 24 Texas companies that went public in 2014 were in the energy sector, according to information compiled by Renaissance Capital, a global IPO investment adviser.

The 2014 total of 275 U.S. IPOs is the most since 2000, when 406 U.S. companies went public. The 2014 total is up 24 percent from the 222 in 2013.
