Inmarsat plc Interim Management Statement

Inmarsat plc (LSE: ISAT.L), the leading provider of global mobile satellite communications services, today provided the following information for the three months ended 31 March 2013.

Inmarsat plc – Highlights

• Total revenue (excluding LightSquared) $310.8m up 2.4% (2012: $303.5m)
• Wholesale maritime MSS revenues up 8.7%
• Strong subscriber growth: FleetBroadband, XpressLink, IsatPhone Pro
• Total active terminals up 16%
• Global Xpress programme on track and budget

Inmarsat Group Limited – First Quarter Highlights

• Inmarsat Global MSS revenues $184.6m up 3.7% (2012: $178.0m)
• Inmarsat Solutions revenues $189.5m (2012: $190.8m)
• Total EBITDA (excluding LightSquared) $154.2m (2012: $157.7m)

Rupert Pearce, Inmarsat's Chief Executive Officer, said, “The improved results from our wholesale MSS business have continued in the first quarter, with positive performances across our business sectors. We have also maintained momentum in subscriber additions for new services. These results provide for continued confidence in our outlook for full year revenues at the wholesale level. Within our Inmarsat Solutions retail segment we have seen results in line with our expectations from three of our four business units. However, in our US Government business unit, we have seen a sudden and pronounced deterioration in both demand and profitability, in each case principally related to US budget cuts. This has led to further margin compression in the Solutions business in the first quarter and we expect the current adverse market conditions for our US Government retail activities to continue for the time being. We aim to substantially mitigate the impact of this changed environment by addressing the cost base for our US Government business unit and by implementing other cost controls across the group. Looking ahead, we are making rapid progress with Alphasat and our Global Xpress programme and our deployment plans remain firmly on track.”

Maritime

Growth in our maritime data revenues was driven by increased take-up and usage of our FleetBroadband service and by pricing and service package changes primarily implemented in May 2012. During the first quarter we added 1,924 FleetBroadband subscribers. With FleetBroadband we are extending our market leadership in the maritime MSS market while we are also making steady progress in the maritime VSAT market with our XpressLink service. Despite the overall maritime revenue growth reported, customer migration to FleetBroadband from certain older services continues to be a constraint on our rate of revenue growth as the price of FleetBroadband services is typically substantially lower than the price of equivalent services on the terminals being replaced. As the number of customers still using our older services declines through the migration process, so the revenue impact of migration reduces over time.

With effect from 1 January 2013, we adjusted the intra-group pricing to Inmarsat Solutions for L-band services used for XpressLink. As XpressLink combines L-band and VSAT services in a single service package, Inmarsat Global applies a charge to Inmarsat Solutions for the L-band element of service. During 2012, the first full year of XpressLink service, we were able to compare actual customer usage trends to our previous assumptions and have updated our pricing accordingly. Had we not adjusted the pricing, we estimate that maritime revenues for the first quarter 2013 would have been $1.7m higher than the figure reported. The pricing adjustment has no impact on the total revenue or margin at a group level.

Land Mobile

In the land mobile sector, the decline in data revenues is due to on-going troop withdrawals from Afghanistan and lower usage by other BGAN users. We estimate that global events including Afghanistan contributed $1.5m more revenue in the first quarter 2012 when compared to the first quarter 2013. Although we continue to see growth in BGAN usage from new subscribers, this growth did not fully offset the impact of reduced revenues from Afghanistan and other customers.

Voice revenue in our land mobile sector increased due to growth in revenues from our IsatPhone Pro service. We ended the first quarter with approximately 90,000 active subscribers and had net additions of over 5,000 subscribers in the quarter. The increase in our installed subscriber base is driving overall traffic growth and is the primary contributor to our voice revenue growth.

Aviation and Leasing

The increase in aviation revenue was driven by strong growth in revenues from our SwiftBroadband service, offset by a decline in Swift 64 revenues, due to lower usage by certain government customers, including usage related to reduced activity in Afghanistan.

The decrease in leasing revenue was due to a reduction in revenue from certain government maritime and aviation contracts, reflecting contracts that were not renewed during the course of 2012 in line with previous expectations.

The decrease in Inmarsat MSS revenue at the Inmarsat Solutions level was driven primarily by a combination of lower leasing revenue and by lower BGAN revenue arising from Afghanistan year-over-year. As Inmarsat Solutions has a disproportionately higher share of both our leasing and BGAN business, the lower revenues from these business lines gave rise to an overall decrease in revenue, even though Inmarsat Solutions benefited from growth in maritime revenues and other factors that contributed to an overall increase in MSS revenue at the wholesale level.

The increase in Broadband and Other MSS revenue was due to increased maritime VSAT revenues as a result of growth in the number of ships using XpressLink. At the end of the quarter we had an installed base of 1,229 ships using our VSAT service, including 418 using XpressLink. There were also increases in equipment sales and other engineering revenues from the Global Government and Enterprise business units, which were partially offset by a reduction in revenue from our US Government business unit. This decrease was primarily a result of contract renewals at lower rates and non-renewals and follows the implementation of defence spending reductions arising as a result of the Federal budget sequestration process. For our US Government business unit, sequestration is likely to result in fewer contracting opportunities as programmes are cancelled, de-scoped or delayed, and significant reduction in margins due to the resultant highly competitive contracting environment.

During the first quarter, growth in Inmarsat Global EBITDA (excluding LightSquared) was primarily driven by increased MSS revenues, offset by a small increase in net operating costs due mainly to higher Global Xpress costs. The decline in the Inmarsat Solutions EBITDA was driven primarily by significant reductions in revenue and increased cost of sales in our US Government business unit.
