EBITDA Up 28 Percent, Revenue Up 22 Percent and Subscribers Up 38 Percent

                                over Q2 2007



    BETHESDA, Md., Aug. 5 /EMWNews/ -- Iridium Satellite LLC today

announced financial results for the second quarter which ended June 30,

2008.



    "Our strong second quarter solidifies our position as the

fastest-growing voice and data mobile satellite services (MSS) company,"

said Matt Desch, Iridium chairman and CEO. "For our fifth consecutive

quarter, we posted double-digit increases for all the important metrics --

revenue, earnings and subscriber gains. As the only MSS provider with a

truly global network, we are benefiting from continued strong usage in our

key vertical markets, as well as from increased demand from enterprise

organizations that depend on Iridium to communicate to and from anywhere in

the world."



    Total revenue in the second quarter 2008 was $81.7 million versus $66.7

million in the same quarter last year, a 22 percent increase. For the

six-month period that ended June 30, 2008, Iridium posted $156 million in

revenue, a 31 percent increase over the first half of 2007.



    Second quarter 2008 EBITDA (Earnings Before Interest, Taxes,

Depreciation and Amortization) of $25.8 million was 28 percent greater than

the second quarter 2007 total of $20.2 million while EBITDA for the first

six months of 2008 was $50.2 million, a 49 percent rise over the same

period in 2007.



    As of June 30, 2008, Iridium had more than 280,000 subscribers

worldwide, a 38 percent increase over the June 30, 2007 total of 203,000.



    The truly global coverage that only Iridium offers continues to be a

differentiating factor when it comes to growth in the MSS market. Iridium

users who operate in Polar Regions generate more than 20 percent of the

company's total annual commercial circuit-switched voice and data usage

revenue. For example, this truly global communications capability is

critical to the aviation industry. In the last five years, cross-polar

flights have grown in importance, providing millions of dollars in fuel

savings and significantly reducing the number of flight hours between

city-pairs. As the number of cross-polar flights has increased, so has the

importance of total, continuous and reliable communications coverage.



    During the second quarter of 2008, the company posted significant

increases over second quarter 2007 in voice and data usage revenues. Voice

traffic in Asia was up 82 percent, in North America it was up 50 percent

and in Europe it was up 45 percent. Iridium continued to demonstrate strong

growth in its data services business. The company's machine-to-machine

(M2M) data revenue grew 92 percent while subscribers grew 154 percent,

making Iridium an increasingly important player in this nascent market.



    Iridium also continues to expand its base in the U.S. government voice

and data services market. In addition to having recently renewed its U.S.

Department of Defense (DoD) Enhanced MSS contract, Iridium continues

development of its Netted Iridium(SM) push-to-talk voice and data service

funded under the DoD Distributed Tactical Communications Service (DTCS)

program. DTCS is a U.S. Navy-funded program designed to deliver enhanced

Iridium voice and data services in support of Over the Horizon (OTH)

tactical communication requirements. Another new application is the

potential use of the Iridium satellite network as an enhancement to the

Global Positioning System (GPS), which has become a vital tool for U.S.

military operations. Use of the Iridium constellation would give some users

of the system more satellites, greater signal strength and added precision.

The U.S. Naval Research Laboratory recently announced it awarded The Boeing

Company a $153 million contract for a High Integrity GPS Technology Concept

demonstration that will leverage the Iridium constellation for

significantly improved performance over stand-alone GPS today.



    Finally, Iridium continues its progress towards deploying the company's

next-generation satellite constellation, "Iridium NEXT." The company

recently announced that it down-selected to two companies -- Lockheed

Martin and Thales Alenia Space -- to participate in the final phase of its

procurement process. Iridium selected these companies based on initial,

innovative constellation design concepts; demonstrated understanding of

performance requirements and capabilities; and initial cost estimates for

the manufacture and launch of Iridium NEXT. By the middle of 2009, Iridium

intends to select one prime contractor to construct Iridium NEXT.
