Ambit Energy Announces Service Growth in New York

Energy provider completes New York expansion with gas and electric service to over 620,000 in the O&R and Central Hudson service

DALLAS – June 13, 2011 – Ambit Energy, a national retail energy provider, announced today
that it will launch electricity and natural gas service in two new territories – Orange and
Rockland Utilities, and Central Hudson Gas & Electric – in late July, completing its retail
expansion in the state of New York.

“We are excited to complete our expansion in New York by bringing exceptional value, great
customer service and our free energy referral program to retail consumers in both the Orange
and Rockland Utilities and Central Hudson service territories,” said Jere Thompson Jr., CEO
and co-founder of Ambit Energy. “This marks a special achievement for Ambit and emphasizes
our commitment to continue our rapid expansion into deregulated markets across the United
States.”

As one of the first retail companies to recognize the opportunity of retail energy deregulation in
New York, Ambit enrolls nearly 13 percent of all New York households switching to an electricity
service company (ESCO) in the markets where it operates.


Reaching new customer milestone
The company surpassed 500,000 active customers in the first quarter of 2011. This milestone is
just one of many recent growth achievements Ambit Energy has seen in the past year as it was
named the No.1 fastest growing private company by Inc. magazine.

“We are excited to bring our Independent Consultants who live or work in these new territories
the opportunity to begin helping their friends and family members save on their monthly energy
expenses,” said Ambit Energy CMO and co-founder Chris Chambless. “Completion of our New
York expansion effort is a key part of reaching our goal of 1,000,000 customers and $1 billion in
annual revenue.”

As a retail energy provider, Ambit Energy buys power wholesale and resells it to retail
customers. Customers are acquired by the company’s team of more than 130,000 Independent
Consultants nation-wide. Ongoing customer relationships are supported by a people-focused,
U.S.-based customer care center utilizing the company’s patent-pending technology platform,
