2001 in Review

Mr. Thompson indicated that 2001 was a year of “major transformation” for
Orbital as the company executed its “back-to-basics” strategy adopted in late
2000. He said principal elements of Orbital’s refocus on its core space
technology products were successfully completed in 2001, including improving
the company’s operational performance, divesting four non-core businesses for
approximately $245 million in proceeds, terminating further investments in
satellite service ventures, and strengthening the company’s balance sheet.
a result of the actions taken in 2001, Mr. Thompson indicated he believes the
company is now positioned for significantly improved financial performance in

Outlook for 2002

With missile defense launch vehicles and geosynchronous communications
satellites leading the way as the company’s primary growth products, Orbital
is looking forward to significantly improved financial performance in 2002,
Mr. Thompson stated.
The company is targeting revenues in excess of $500
million, with operating profit margins in the range of 4 to 5%.
He said the
company is targeting all four quarters of 2002 to generate positive net income
and that the year began on an upbeat note with the $2.4 million net income, or
$0.05 earnings per share, that the company reported for its first quarter
earlier this week.

Mr. Thompson indicated that while Orbital has clearly established positive
momentum over the past several quarters, challenges for the company remain
ahead in 2002.
Specifically, he cited the need to address the company’s $100
million convertible bonds that mature on October 1, 2002, together with a
focus on large-scale ramp-up of the company’s operations on new programs like
the recently awarded missile defense boost vehicle contract, as well as
continued discipline in the areas of cost control, cash management and program
