Ambit Energy Ends Record Year with Two Recognitions

Retail energy provider grows to become a Metroplex business leader

DALLAS – Jan. 31, 2011 – Ambit Energy, a national retail energy provider, has been recognized by
two distinguished regional award programs, the SMU Cox Dallas 100™ and Top 100 Places to Work by
Dallas Morning News for the second consecutive year.

“It is an honor to be acknowledged not just for our strong growth in sales but also for our culture, our people
and the value we deliver to our customers,” said Jere Thompson, Jr., co-founder and CEO, Ambit Energy.
“Our mission to be the finest and most respected retail energy provider in the country is built upon delivering
the best service and value to our customers, while hosting an honest, friendly workplace for our employees.”

For two years in a row, Ambit Energy ranked number one on the SMU Cox Dallas 100™ list. The 2010 Dallas
100™ award winners were chosen based on increased growth in sales, both percentage of growth and
absolute dollar growth between 2007 and 2010. In order to qualify for the Dallas 100™, a company must be
an independent, privately held corporation; be headquartered in the Dallas area; have had sales of more than
$500,000 in fiscal 2007; have had sales of not more than $75 million in 2007; have a three-year sales
history reflecting growth; and, have a credit report and character satisfactory to the Dallas 100™, determined
at the sole discretion of the Dallas 100™.

Ambit Energy was also ranked 24 for top midsize company on the Dallas Morning News’ Top 100 Places to Work
2010 list, which recognized area companies who excel at creating and maintaining a dynamic, supportive and
inclusive workplace despite the economic climate. Ambit Energy was one of only 18 companies that made the
list two years in a row.

“It’s our people and our culture that make Ambit Energy a great place to work,” said Chris Chambless,
co-founder and CMO, Ambit Energy. “We are strong believers in an open environment that facilitates rapid
communication and in turn allows us to attract and retain bright, creative people who share our passion
for serving our growing base of customers and consultants across the country.”
Ambit Energy was also honored earlier this year by Inc. magazine’s Inc. 500 list as “America’s Fastest-Growing
Private Company,” reaching the top of the list when the company hit a three-year sales growth of more than
20,000 percent between 2006 and 2009.
