DULLES, Va., Aug 1, 2001 /PRNewswire/ --

- Company Completes Two Non-Core Business Unit Sales, Reduces Debt By $150 Million in Last Three Months -

Orbital Sciences Corporation (NYSE: ORB) today announced financial results for the second quarter of 2001, reporting net income of $66.6 million, or $1.75 earnings per share, compared to the second quarter 2000 net loss of $42.1 million, or $1.13 loss per share. The company's second quarter 2001 results include a net gain of $90.7 million from the sale of two non-core business units.

During the second quarter of 2001, Orbital sold 16.35 million shares of MacDonald, Dettwiler and Associates Ltd. (MDA) of Canada for approximately $150 million, and in July 2001 the company completed its MDA divestiture with the public sale of its remaining ownership interest of 1.65 million shares for approximately $19 million. Orbital also completed the sale of its Magellan Corporation subsidiary and the company's interest in the Navigation Solutions (NavSol) joint venture in July 2001 for approximately $70 million. The proceeds from these divestitures have been used in part to reduce debt by over $150 million since March.

"In the second quarter, we achieved two significant milestones in executing our plan to restore value for our shareholders. First, we remained on track to improve the basic operating performance of our space technology units, generating good financial results in all core product lines except for a few satellite programs now approaching completion. With the addition of profitable new orders in these areas, our outlook remains positive for their future performance," said Mr. David W. Thompson, Orbital's Chairman and Chief Executive Officer.

"Second, we substantially enhanced the company's financial condition by reducing debt and increasing cash. In less than a year, we have completed three major non-core business unit sales, allowing us to focus full management attention on our core space businesses and raising over $350 million of total proceeds to strengthen our financial position," Mr. Thompson added.

Financial Highlights

Summarized financial results for the second quarter of 2001 as compared to the second quarter of 2000 are as follows ($ in millions, except per share data):

Revenue

Orbital's revenues were $118.6 million in the second quarter of 2001, a 7% decrease compared to revenues of $128.0 million for the same period last year (adjusted for the October 2000 sale of the company's Fairchild Defense unit). Several items negatively affected the company's second quarter 2001 revenues as compared to those for the second quarter 2000, including NASA's March 2001 termination for convenience of the X-34 rocketplane contract and the mid-2000 suspension of revenue recognition under the company's procurement agreements with ORBCOMM and ORBIMAGE.

Operating Income

Orbital's second quarter 2001 operating loss was $7.7 million as compared to an operating loss of $6.2 million for the same period last year (adjusted for the October 2000 sale of the company's Fairchild Defense unit). The primary factors contributing to the second quarter 2001 operating loss were continued cost increases on two satellite manufacturing programs that are nearing completion in the third quarter. In addition, second quarter 2001 results include an adjustment of contract revenues associated with the unsuccessful Arianespace S.A. launch of the Orbital-built BSAT-2b satellite. As previously reported, because of an Ariane 5 rocket launch anomaly in mid- July, this satellite did not reach its intended orbit. Orbital believes it has adequate insurance coverage to cover this situation; however, certain amounts anticipated to be recovered under the insurance policy have been excluded from contract revenues, resulting in a reduction of second quarter 2001 revenue and operating income of approximately $3.5 million. Insurance proceeds to be recovered under this policy will be reported as "other income" in the period such proceeds are received.

Net Loss from Continuing Operations

Orbital reported a net loss from continuing operations in the second quarter of 2001 of $24.2 million, a significant improvement over the second quarter 2000 loss from continuing operations of $42.3 million (adjusted for the October 2000 sale of the company's Fairchild Defense unit). This improvement was primarily due to equity losses associated with the company's ORBCOMM satellite communications affiliate and a litigation settlement accrual in the second quarter of 2000, which did not exist in 2001.

New Business Highlights

During the second quarter of 2001, Orbital received new firm orders and options for its space technology products valued at approximately $150 million. As a result, after eliminating backlog associated with MDA, the company's firm contract backlog as of June 30, 2001 was approximately $530 million, and its total contract backlog (including options, undefinitized orders and indefinite-quantity contracts) was approximately $2.94 billion. Additions to total backlog during the second quarter of 2001 included the following:

    *  Orbital was selected by the National Aeronautics and Space
       Administration (NASA) for two contracts, totaling approximately $53
       million in value, as part of the space agency's Space Launch Initiative
       (SLI) program.  Orbital was selected to design, build and operate the
       Pegasus-launched Demonstration of Autonomous Rendezvous Technology
       (DART) space vehicle.  In addition, the company was selected to
       continue its work to develop future space transportation architectures
       for NASA.

    *  Orbital's Taurus rocket was selected by the Republic of China's
       National Space Program Office for a $37 million contract to launch the
       ROCSAT-2 remote sensing satellite.  Orbital will use the higher-
       performance Taurus XL version of its ground-launched rocket for this
       mission.

    *  Orbital was awarded a contract for $11 million to develop a design
       concept for a new booster vehicle for the U.S. Government's missile
       defense initiative.  In addition, Orbital will assume the role of
       primary target vehicle supplier for national missile defense tests
       using one of its sophisticated suborbital rockets beginning this fall.
Operational Highlights

The company carried out 5 space missions in the second quarter and, with several additional operational events in July, has conducted a total of 13 missions so far in 2001. Recent operational highlights include the following:

    *  After its launch in early March, Orbital's BSAT-2a satellite, the first
       of two GEO direct-to-home digital television broadcasting platforms
       built for Japan's Broadcasting Satellite System Corporation (B-SAT),
       successfully completed its in-orbit testing and was placed into
       commercial service at the end of April.  The spacecraft is currently
       providing television programming to millions of Japanese households.

    *  Orbital also successfully completed and delivered for launch BSAT-2b,
       the second of the two B-SAT television broadcasting satellites.
       Unfortunately, the mid-July launch provided by Arianespace, aboard its
       Ariane 5 rocket, did not achieve the mission's intended orbit and
       placed the spacecraft in a non-usable orbit.

    *  The OrbView-4 high-resolution imaging satellite, which Orbital
       developed and manufactured for ORBIMAGE, completed factory testing in
       June and was shipped to the mission launch site at Vandenberg Air Force
       Base, California in July.  Orbital also shipped the mission's secondary
       satellite, the QuikTOMS science spacecraft that the company built for
       NASA, to Vandenberg in June.  Both satellites will be launched aboard
       the company's Taurus rocket, which is currently scheduled for lift-off
       in early September.

    *  The NASA-led X-43/Hyper-X Mishap Investigation Board (MIB) is
       continuing its review of flight data to determine the cause of the
       failure of the company's Hyper-X launch vehicle that occurred in early
       June.  As a result, NASA has delayed the launch of its HESSI scientific
       satellite aboard the company's Pegasus rocket, which shares certain
       systems and technology with the Hyper-X launch vehicle.  Once the MIB
       determines there is no common technical issue between Pegasus and
       Hyper-X, the HESSI mission will be rescheduled.
ORBIMAGE Update

ORBIMAGE is continuing its efforts to restructure its debt, which is non- recourse to Orbital, and to obtain new capital from existing shareholders as well as third parties. Orbital, certain of ORBIMMAGE's other shareholders and its bondholders are currently negotiating terms of a proposed restructuring.

"The back-to-basics strategy that we embarked on 18 months ago was established to increase value for our shareholders by improving core business performance, strengthening our balance sheet and increasing our financial flexibility," said Mr. Thompson. "While significant progress has been made so far this year, we still must complete several critical satellite programs and achieve full cost efficiencies in our core manufacturing businesses to return to the favorable operating margins that we enjoyed in past years," he concluded.

Orbital is one of the world's leading manufacturers of affordable space systems, including satellites, launch vehicles, space sensors and electronics, and advanced systems. Orbital is also involved with satellite-based networks that provide wireless data communications and high-resolution Earth imagery to customers around the world.
