Inmarsat Holdings Limited Reports First Quarter 2009 Results

LONDON - Inmarsat Holdings Limited, a wholly-owned subsidiary of Inmarsat plc (LSE: ISAT), the leading provider of global mobile satellite communications services, today reported unaudited consolidated financial results for the 3 months ended 31 March 2009.

Highlights

- Revenue up 10.5% to $163.4m (2008: $147.9m) - EBITDA up 13.2% to $117.3m (2008: $103.6m) - Profit after tax up 35.3% to $39.1m (2008: $28.9m) - Global broadband coverage completed - Repositioning of Inmarsat-4 fleet completed - Acquisition of Stratos Global completed on 15 April - New distribution agreements signed

Andrew Sukawaty, Inmarsat’s Chairman and Chief Executive Officer said, “Our first quarter results deliver yet another quarter of strong growth and underline the resilience of our markets thus far to the wider economic climate. In particular, we have been able to sustain growth in maritime revenues despite the challenges facing the global shipping industry. With these factors in mind, we remain confident in our revenue growth objectives for the full year.

In addition, our cost control and significantly reduced capital expenditure needs meant that free cash flow for the quarter improved by over $50m compared to the first quarter last year.

In April we announced that we had signed new distribution agreements with all our major partners and that Inmarsat plc had completed the acquisition of Stratos Global Corporation. We believe these events will support our revenue growth and increase the value of our business.”

Mobile Satellite Services

During the first quarter our maritime sector revenue saw growth of 2.3% across voice and data services. Maritime revenue in the first quarter was adversely impacted by higher volume discounts year over year, primarily as a result of a more even phasing of volume discounts expected for the full year. Adjusted for the impact of volume discounts, the underlying growth in the maritime sector was 7.7% for the first quarter. Total maritime active terminals grew by 11.5%, fuelled by demand for our Fleet and new FleetBroadband services, but also by demand for Inmarsat-C terminals. The number of active Fleet and FleetBroadband terminals was up 34% year over year.

First quarter land mobile sector revenue was up 10.6% with growth in land data of 13%. Reported active land terminals at the end of the first quarter were up 0.4%, but taking into account the impact of our discontinued R BGAN service, active land terminals were up 10% year over year. Growth in land data continues to be driven by strong take up and usage of our BGAN services.

Our first quarter aeronautical sector revenue grew by 32%. Aeronautical growth continues to be driven primarily by strong usage and take up of our Swift 64 service. Although still at an early stage, we continue to see encouraging demand for our SwiftBroadband service. During the quarter Ryanair launched an in-flight passenger connectivity service on 20 of its aircraft using our SwiftBroadband service.

Our first quarter leasing revenue was up 40% year over year, reflecting the on going benefit of incremental new leases signed in 2008 together with a consistently high level of lease renewals.

Liquidity

At 31 March 2009, Inmarsat Holdings Limited had net borrowings of $970.2m, incorporating borrowings of $1,058.1m and cash of $87.9m. Inmarsat Holdings Limited also had a revolving credit facility with an amount available but undrawn at the end of the quarter of $160.0m. Net borrowings reported by Inmarsat Holdings Limited exclude the net borrowings of Inmarsat plc and Stratos Global Corporation. The Inmarsat Holdings Limited group is generating significant free cash flow and considers its available liquidity to be comfortable for the group’s needs.
