AAON Reports Record Sales and Earnings


TULSA, OK--(Marketwire - March 12, 2008) - AAON, Inc. (NASDAQ: AAON) today announced its operating results for the year 2007. Sales increased 13% to $262.5 million from $231.5 million in 2006, and net income increased 36% to $23.2 million compared to $17.1 million in the previous year. Both sales and net income were all-time record highs.

Norman H. Asbjornson, President and CEO, stated that, "The increase in sales was attributable to an increase in volume of products sold as a result of an improvement of the commercial and industrial construction industry, an increased demand for the Company's new and redesigned products, and price increases during 2007. The increase in earnings resulted from both higher volume and price increases, which provided an improvement in gross margins."

Sales in the fourth quarter of 2007 increased to $62.1 million, up 14% from $54.6 million in 2006, and net income for the fourth quarter increased to $4.6 million, compared to $4.5 million in 2006. Sales and net income were the highest for any fourth quarter in the Company's history.

Earnings per diluted share for 2007 were $1.22 compared to $0.90 in 2006. Earnings for the fourth quarters of 2007 and 2006 were $0.24 per diluted share.

Mr. Asbjornson said, "While we expect record sales and earnings in the first quarter of 2008, due to uncertain market conditions it is too early to predict outcomes for the balance of this year."

AAON, Inc. is a manufacturer of air-conditioning and heating equipment consisting of rooftop units, chillers, air-handling units, condensing units and coils.
