-- 14.7% Earnings Per Share Increase -- Nineteenth Consecutive Quarter of Year-Over-Year EPS Increases

WOOD DALE, Ill., /PRNewswire/ -- AAR CORP. (NYSE: AIR) announced today that for the Company's fiscal year 2000 first quarter ended August 31, 1999, net sales increased 13.9% to $245.9 million, the highest quarterly sales in the Company's history. After adjusting for the divestiture of the Company's industrial products manufacturing business, net sales increased 16.8%. Net income grew to a first quarter record $10.8 million, a 12.6% increase over last year, and diluted earnings per share increased 14.7% to $0.39 from $0.34 a year ago. It was the Company's 19th consecutive quarter of year-over-year earnings per share increases.

''I am pleased with our results in the first quarter of fiscal 2000,'' AAR President and Chief Executive Officer David P. Storch said. ''AAR's sustained growth in both revenue and earnings demonstrates the effectiveness of our strategy of providing customized, value-added products and services to a diversified customer base. In particular, we continue to benefit from our industry leading capabilities in providing outsourced inventory management and overhaul programs. ''

AAR's Aircraft and Engines revenues grew 33.1% over the same quarter last year to $119.9 million. Airframe and Accessories revenues reached $96.1 million, an increase of 3.5%. Manufacturing revenues were $29.9 million. Adjusting for the November 1998 sale of the industrial floor products unit, revenues in this group grew 8.6%.

''With a broad line of products and services, an international customer base, and an established presence in commercial, government/military and general aviation, AAR is well positioned to take advantage of growth opportunities wherever they present themselves,'' Storch said.

Other significant activities in the first quarter included the following:

    -- Condor/Cargo Technik of Frankfort, Germany awarded AAR an exclusive,
       multi-year agreement for the supply of exchange landing gear for
       Condor's fleet of 767 aircraft. As part of its service, AAR will employ
       its innovative, award-winning "Tiger Teams" to perform interim
       inspections of landing gear to keep Condor's fleet in compliance with
       both FAA/JAA and Boeing requirements.

    -- The U.S. Marshals Service exercised its option to renew its contract
       with AAR to provide line maintenance, scheduled heavy maintenance and
       inventory supply and management in support of its fleet of 12 or more
       aircraft.

    -- AAR was selected as sole distributor for Allied Signal's Grimes brand
       of lighting products, including anti-collision, interior, cockpit,
       emergency, navigational and landing lights for business and general
       aviation.
