       Key Technology Sales Rise 18% for FY2003 and 21% for Q4;
           Full Year Diluted EPS hits $1.15, Backlog up 33%

    WALLA WALLA, Wash.--(BUSINESS WIRE)--Nov. 6, 2003--Key Technology,
Inc. (Nasdaq:KTEC) today announced sales and operating results for the
fourth quarter and year ended September 30, 2003.
    Sales for the three-month period ended September 30, 2003 totaled
$21.3 million, up 21% from the $17.6 million recorded in the same
quarter last year. Net earnings for the quarter were $1.4 million, or
$0.27 per diluted share compared with net earnings of $0.4 million, or
$0.08 per diluted share in the same period a year ago.
    Sales for the year ended September 30, 2003 increased 18% to $82.6
million compared with $70.2 million for fiscal 2002. The Company
reported net earnings for the year of $5.8 million, or $1.15 per
diluted share compared with a net loss of $2.0 million, or $0.53 per
diluted share for fiscal 2002. Fiscal 2002 results included a $4.3
million charge for the impairment of goodwill resulting from the
Company's implementation of SFAS No. 142. Excluding this charge, net
earnings from continuing operations for fiscal 2002 were $2.3 million,
or $0.36 per diluted share.
    "Our fourth quarter results are gratifying and contributed to
solid performance for fiscal 2003. We are pleased that our continued
focus on customers, execution, and operational efficiencies resulted
in both revenue growth and a strong bottom line," commented Kirk
Morton, President and Chief Executive Officer.
    Gross profit for the fourth quarter of fiscal 2003 was $8.6
million compared to $6.6 million in the corresponding period last
year. As a percentage of sales, gross profit was 40.4% compared to
37.8% in the fourth quarter of fiscal 2002. For the twelve-month
period, gross profit was $34.0 million compared to $27.9 million for
the same period of fiscal 2002, or 41.1% and 39.7% as a percentage of
sales, respectively. Margins for the year were favorably impacted by
an increased mix of higher-margin equipment and parts, manufacturing
efficiencies attributable to volume, lower warranty costs, and cost
reductions due to global sourcing of certain high-use components and
sub-assemblies.
    Operating expenses for the quarter ended September 30, 2003 were
$6.4 million, or 30.2% of sales compared to $5.6 million, or 32.0% of
sales in the same quarter last year. Operating expenses for the year
ended September 30, 2003 were $25.2 million, or 30.5% of sales
compared to $23.5 million, or 33.4% of sales for fiscal 2002.
    New orders received during the fourth quarter were $23.2 million,
compared to $13.6 million in the same period last year. The Company's
$20.1 million backlog at September 30, 2003 reflects a 33% increase
compared with the $15.1 million backlog at the close of fiscal 2002.
The Company previously announced on October 2, 2003 that it had
received orders totaling more than $6.0 million from two major
customers in the food processing industry. Those orders are included
in both the bookings for the fourth quarter and the 2003 year-end
backlog figures and will ship in the first half of Key's fiscal year
2004.
    Morton commented, "The order volume in the fourth quarter was the
highest recorded in the Company's history for that period and reflects
what we believe is an improving capital investment environment among
our customers. We are particularly pleased that we are winning orders
for multiple systems from our larger customers, as this bodes well for
future business. While we anticipate some normal seasonal effects
during the first quarter of the new fiscal year, we are encouraged
with our healthy year-end backlog and are optimistic about our
prospects in fiscal year 2004."
    For the fiscal year, cash flow from operating activities increased
30% to $14.5 million from $11.2 million in fiscal 2002 reflecting
stronger earnings and focused balance sheet management. During the
fiscal year, interest-bearing debt was reduced from $12.0 million to
$4.3 million.
    Commenting on the outlook for the new fiscal year, Morton said,
"We are monitoring investment patterns in the global French fry
market, given the declining consumer consumption in North America, and
do not expect revenue growth from this segment in 2004. However, we do
expect to see increased revenues in the North American and Western
European processed vegetables segment, in the food processing sector
in Asia -- particularly in China, and from our optical inspection
product lines in Europe. We also expect another good year from the
tobacco market segment.
    "We have reorganized our operations to add considerable resources
in marketing and product management, consistent with our renewed focus
on revenue growth following our recent emphasis on debt reduction and
asset management. In addition, we continue to invest in research and
development and anticipate the completion of several new product
developments in late 2004 and early 2005 which will allow us to enter
new market segments and meet specific needs of certain of our largest
customers."
