Ameristar Launches Online Supplier Registration
Minority- and Women-Owned Businesses Encouraged to Participate

(AANEWSWIRE)Las Vegas, Nev., January 24, 2007 - Ameristar Casinos, Inc. (Nasdaq: ASCA) today launched a new automated supplier registration
process through the company's website at www.ameristar.com. The new online procedure will streamline bidding and contracting with vendors and service-providers for a wide variety of products and services. In the future, Ameristar will utilize the website's supplier database to generate additional bid opportunities for all suppliers that register.
The company especially encourages minority- and women-owned
businesses at the local, regional and national level to register through
the website. As part of Ameristar's ongoing commitment to diversity and
inclusion throughout our business, we are hopeful that the new automated
registration process will facilitate increased participation by
minority- and women-owned businesses in our bidding and contracting.
"Ameristar is committed to procuring goods and services from
suppliers who can deliver the high-quality products that reflect our
brand standards and provide the same level of outstanding service to us
that we provide to our guests," said CEO and President John Boushy. "We
constantly strive to provide the leading casino and entertainment
facility in each of our markets. Our suppliers and service-providers
play an integral role in helping us meet that goal."
"Ameristar also values inclusion in our procurement practices,"
continued Boushy. "We actively partner with women-owned and
minority-owned businesses as providers of millions of dollars in goods
and services each year. I'm optimistic that this new online
registration process will allow us to create even more valuable
partnerships with diverse vendors that share our company's commitment to
quality and innovation." At Ameristar, we are committed to celebrating and appreciating diversity and inclusion as an integral part of our business and a
critical factor in our company's success. Our diversity efforts focus
on hiring and leadership development, procurement for ongoing operations
and construction activities, and charitable giving. A number of our
executives serve in leadership positions of various diversity-related
organizations, such as the American Gaming Association's Diversity Task
Force and the MidAmerica Minority Business Development Council, and we
participate in job fairs, vendor fairs and other programs to improve
diversity and inclusion throughout our company and our industry. Our
commitment to diversity is exemplified by programs such as our
five-year, $1 million grant to the Kansas City Port Authority to fund a
foundation for the advancement of women and minorities in business.
