Andrew Sukawaty, Inmarsat's Chairman and Chief Executive
Officer said, "Our results for the first half and second quarter show that we
are on track for solid revenue growth in 2009. In particular, the continuing
strong performance of our maritime business, driven by revenue from new
services, shows that we are more than offsetting the impact of reduced
shipping volumes and vessels not in use. Furthermore, our EBITDA growth and
free cash flow remain strongly positive."

Inmarsat Global results

Our Inmarsat Global[2] business delivered growth in MSS
revenue of 9.2% for the half year ended 30 June 2009. Maritime growth,
adjusted for the impact of volume discounts, was up 9.8% for the first half
and was driven by high usage levels across our Fleet, FleetBroadband and
Inmarsat B services.

The land mobile sector saw BGAN revenue growth of 32% in the
first half and 4,261 subscribers were added. Our land mobile sector revenue
growth overall was 0.6% for the first half and was impacted by a number of
factors, including the implementation of new pricing incentives which are
expected to encourage new demand in the future.

Our aeronautical and leasing sectors continued to see strong
revenue growth, being up 25% and 30% respectively in the first half. Net
operating costs for Inmarsat Global were down 1.3%, contributing to growth in
EBITDA of 12.0%.

Growth in active terminals in the first half of 2009 was 7.3%.
The rate at which Inmarsat Global added new active terminals in key services,
such as BGAN, Fleet and FleetBroadband, remained consistent throughout the
first half of 2009.

Stratos results

Our Stratos business delivered revenue growth of 2.5% for the
half year ended 30 June 2009. Stratos' results saw first half MSS revenue
growth of 6.2%, offset by lower Broadband revenues. While MSS revenue grew
sequentially from the first to second quarter, second quarter[3] revenue was
marginally weaker year over year, when compared to a particularly strong
second quarter in 2008. Operating costs for the Stratos business were up 2.0%
in the first half, contributing to growth in EBITDA of 5.5%.

Liquidity

Our liquidity position remains strong and we are well
positioned to meet our funding needs. At 30 June 2009, the Group had net
borrowings of $1,414.1m, made up of cash of $173.1m and total borrowings of
$1,587.2m. Taking into consideration our cash resources and available but
undrawn borrowing facilities of $185.0m, the group had total available
liquidity of $358.1m at 30 June 2009. On 16 July we announced that Inmarsat
Global had signed a new $500.0m forward starting senior credit facility. The
new facility will mature in May 2012 and is available to replace Inmarsat's
existing senior facility which matures in May 2010.

Outlook

We continue to see positive trading conditions in our key MSS markets.
Importantly, our maritime sector results have maintained healthy growth
despite the demand and capacity factors impacting the global shipping
industry. A high proportion of our revenue comes from government customers
and, in addition, our commercial users tend to have a high degree of
day-to-day reliance on our services. As a result of these factors, we are on
track for solid revenue growth and a positive overall performance for the
Group in 2009.
