Heathrow (SP) Limited

Consolidated results for the three months ended 31 March 2014

Contents

1 Key business developments

1.1 Passenger traffic

Heathrow's passenger traffic by geographic segment for the three months ended 31 March 2014:

(1) Calculated using unrounded passenger numbers

For the three months ended 31 March 2014, Heathrow's traffic rose 0.5% to 16.0 million passengers (2013: 16.0 million), with an average load factor of 70.7% (2013: 71.9%). Traffic and load factors were impacted by the timing of Easter which shifted the holiday demand peak from March in 2013 to April in 2014. Taking into account the movement in the timing of Easter, the underlying rate of growth for the first three months of 2014 is estimated to be in the region of 2%.

Airlines continue to operate larger planes with 203.2 seats on average per aircraft (2013: 199.9 seats). Overall air traffic movements increased by 0.6%, with a shift to more intercontinental services.

Domestic traffic grew 7.8%, continuing to reflect the launch of UK domestic services by Virgin Atlantic Little Red in summer 2013. European traffic was 1.4% lower than last year in part impacted by Easter timing and also reflecting a shift of slot usage to long haul services. Intercontinental traffic performed well in most regions, growing by 1.0%. North America benefitted from increased services from a number of airlines and traffic increased 1.6%. Other intercontinental regions also grew, with the exclusion of Africa which mainly reflects the withdrawal of routes previously operated by bmi.

1.2 Service standards

Heathrow's quality of service and facilities received further endorsement at the 2014 Skytrax World Airport Awards. Terminal 5 was named the world's 'Best Airport Terminal' for the third year in a row and Heathrow was named the 'Best Airport for Shopping' for a fifth consecutive time. The Skytrax World Airport Awards are independent of any airport input and assess customer service and facilities across 388 airports, providing an impartial benchmark of airport excellence and quality.

Heathrow has continued to achieve strong recognition from the travelling public for service performance. In the independent Airport Service Quality (ASQ) survey directed by Airports Council International (ACI), a record 80% of passengers surveyed in the first three months of 2014 rated their experience as 'Excellent' or 'Very Good'. This surpasses the levels of improvement attained in 2013.

Heathrow achieved record overall passenger satisfaction in the ASQ survey for the first quarter of 2014, with an ASQ score of 4.06 out of 5.00. The score reflects a strong operational performance, record levels of punctuality and an overall improvement in passenger experience in security and immigration.

In relation to individual service standards, during the three months ended 31 March 2014, departure punctuality (the proportion of aircraft departing within 15 minutes of schedule) was 83.6% (2013: 75.7%). Heathrow's baggage misconnect rate was 14 per 1,000 passengers (2013: 15).

The security queue experience remains a key priority of the business and a range of initiatives have been implemented which have begun to yield improvements. Passengers passed through central security within the five minute period prescribed under the Service Quality Rebate scheme 95.9% of the time (2013: 92.9%) compared with a 95% service standard.

For Heathrow's new regulatory period that commenced on 1 April 2014 new Service Quality Conditions are being implemented and are designed to safeguard performance improvement in passenger satisfaction. These include implementation of new security queue measurements on a per passenger basis, with a requirement for 99% of passengers to pass through security within 10 minutes; delivery of passenger experience standards such as cleanliness of facilities and way-finding; and the availability of airfield equipment to enable efficient flight operations. For each element a baseline performance level has been set by the CAA.

1.3 Investing in Heathrow

Terminal 2: The Queen's Terminal is on schedule for operations to begin on 4 June 2014. Extensive trials of the facility and familiarisation activities for the 24,000 staff that will work at Terminal 2 are underway. Two major end-to-end proving trials have taken place, with two further major trials scheduled. Over 4,000 volunteers acting as passengers together with staff from the 160 different organisations that will work at Terminal 2, have participated in the end-to-end trials.

The £2.5 billion investment comprises a main terminal building and a satellite building, together with a multi-storey short-stay car park and an energy centre that supports the Terminal 2 campus and the wider airport. The terminal will ultimately cater for up to 20 million passengers each year and will be home to all 23 Star Alliance airlines operating at Heathrow together with Aer Lingus, Virgin Atlantic Little Red and germanwings. United Airlines will be the first to operate at Terminal 2 from 4 June, followed by a phased move of airlines into the terminal over the following five months. Most new terminal openings worldwide face challenges. As well as the extensive trials and familiarisation activities taking place, the phased transition of airlines moving into the terminal should reduce the impact of any challenges that arise. The transition builds from 17 daily departures on day one to 176 daily departures once all airlines have moved in.

Investment in Heathrow's baggage infrastructure continues in 2014. The underground automated baggage system between Terminal 3 and Terminal 5 is now fully operational. Delivery of the Terminal 3 integrated baggage system remains on track to start operation in 2015. The integrated baggage system is housed in a separate building and will provide Terminal 3 with an integrated departing and transferring baggage system. The baggage building is now complete, the systems are being tested and commissioned and operational readiness trials have started.

Elsewhere, capital investment in 2014 will focus on areas such as refurbishment of tunnels, refurbishment of the northern runway, asset replacement and investment in operational resilience.

1.4 Heathrow's business plan

The new regulatory period for economic regulation of Heathrow ('Q6') began on 1 April 2014 and will be in force until 31 December 2018. The CAA set the price controls for the period, under which the annual change to the maximum allowable yield per passenger will be RPI minus 1.5%. On 28 March 2014, the CAA formally confirmed that no party sought permission to appeal the decision on the price controls at Heathrow.

Heathrow's business plan for the Q6 period has been refined, taking into account the regulatory settlement. The plan is challenging and the business is focussed on delivering operating efficiencies and commercial improvements, whilst sustaining passenger experience and operational resilience.

1.5 Airports Commission

At the end of 2013, the Airports Commission chaired by Sir Howard Davies published its interim report on the steps needed to maintain the UK's global hub status. The Commission stated that there is a clear case for at least one net additional runway in London and the South East by 2030 and Heathrow's proposal for a third runway to the north west of the existing airport facilities was shortlisted for further refinement.

Heathrow has since worked with local authorities, communities and other stakeholders to refine the runway option, including public consultation which took place through February and March.

Heathrow's expansion proposal would raise the capacity at Heathrow to 740,000 flights a year, from the current limit of 480,000. It would cater for up to 130 million passengers annually compared with up to 80 million today, allowing the UK to compete with international rivals and providing capacity for the foreseeable future. Refinements to Heathrow's proposal will be submitted to the Airports Commission on 14 May 2014 and Heathrow will continue to work with the Airports Commission and stakeholders on the proposals. The Airports Commission is due to report its final findings in summer 2015.

1.6 Significant management changes

On 1 April it was announced that Colin Matthews will be standing down as Chief Executive Officer of Heathrow later this year.

Colin Matthews joined Heathrow in March 2008. Under his leadership the proportion of passengers rating their journey through Heathrow as very good or excellent has increased from less than 50% to 80%. Terminal 5 has been voted by passengers as the world's best airport terminal for the past three years. Heathrow has constructed a brand new Terminal 2, which is set to open to passengers in June. The airport successfully welcomed the world to Britain as the official gateway for the London 2012 Olympic and Paralympic Games.

Heathrow has commenced a search for a successor for Colin Matthews with the aim of having a new Chief Executive in place later this year and after Terminal 2: The Queen's Terminal has opened. Colin Matthews will remain as Chief Executive until his successor is in place to ensure a smooth transition.

2 Financial review

2.1 Basis of preparation

Heathrow (SP) Limited ('Heathrow (SP)') is the holding company of a group of companies that owns Heathrow airport and operates the Heathrow Express rail service (the 'Group'). The Group's statutory accounts and quarterly reports are prepared under UK GAAP. Unaudited consolidated financial information is set out in Appendix 1. Stansted is treated as a discontinued operation in the prior year operating financial information.

2.2 Profit and loss account

2.2.1 Introduction

(1) Adjusted operating costs are stated before depreciation, amortisation and exceptional items

(2) Adjusted EBITDA is earnings before interest, tax, depreciation and amortisation and exceptional items

2.2.2 Turnover

In the three months ended 31 March 2014, Heathrow's turnover increased 10.8% to £576 million (2013: £520 million).

2.2.2.1 Aeronautical income

Heathrow's aeronautical income increased 18.3% to £356 million (2013: £301 million). Average aeronautical income per passenger increased 17.6% to £22.20 (2013: £18.87).

The strong performance reflects the increases in the headline tariffs for the 2013/14 regulatory year. In addition, the non-recurrence of yield dilution which occurred in the first three months of 2013, together with recovery of yield dilution in the 2011/12 regulatory year through the 'K' factor mechanism contribute to the increase.

2.2.2.2 Retail income

In the three months ended 31 March 2014, Heathrow's retail income increased 0.9% to £108 million (2013: £107 million). Net retail income ('NRI') grew 1.0% to £102 million (2013: £101 million) and NRI per passenger rose 0.5% to £6.36 (2013: £6.33).

Car parking revenue continued to be strong in the first three months of 2014, growing by 9.5%. Bureaux de change generated lower income than last year, the underperformance relates to the timing in a change of supplier, where an interim arrangement has been in place since late 2013. The new supplier terms are expected to yield benefits from April onwards.

Retail stores including duty and tax-free and luxury outlets performed flat to last year. This partly reflects the commencement of a significant extension of the luxury retail space in Terminal 5 which is expected to cause some disruption to existing activities. As one of the key initiatives to further develop Heathrow's award winning retail activities in the new regulatory period, the extension should deliver growth in retail income. Performance was also likely to have been impacted by the strength of sterling relative to the same period last year and the shift in the Easter holiday peak demand from March in 2013 to April in 2014.

2.2.2.3 Other income

Other income totalled £112 million in the three months ended 31 March 2014 and was unchanged from the same period last year. Gains in income from rail, property rental and operational facilities, were broadly offset by a reduction in income from provision of utilities.

2.2.3 Adjusted operating costs

Adjusted operating costs exclude depreciation, amortisation and exceptional items.

In the three months ended 31 March 2014, adjusted operating costs reduced by 7.6% to £257 million (2013: £278 million).

Performance in underlying operating costs continues to improve. Costs in the first three months of 2013 were impacted by one-off employment expenses of around £7 million and costs to maintain operations during adverse weather. Stripping out the one-off expenses from 2013, operating costs in the first three months of 2014 reduced by approximately 3.7%.

Employment costs continue to be a focus for the business and major restructuring of Heathrow's corporate centre is mainly complete and delivering benefit. Changes in a major baggage contract implemented in the final quarter of 2013 are delivering benefits in employment costs and general expenses.

Underlying efficiencies in operating costs will continue through 2014, these partially offset the increased costs in rent and rates, utilities and general expenses that will be incurred when operations begin at Terminal 2.

2.2.4 Adjusted EBITDA

In the three months ended 31 March 2014, Adjusted EBITDA increased 31.8% to £319 million (2013: £242 million), resulting in an Adjusted EBITDA margin of 55% (2013: 47%). The increase in Adjusted EBITDA principally reflects the increase in aeronautical income and the reduction in operating costs.

2.2.5 Operating result

The Group recorded an operating profit for the three months ended 31 March 2014 of £165 million (2013: £114 million). Reconciliation of Adjusted EBITDA and statutory operating result is provided below.

2.2.6 Exceptional items

In the three months ended 31 March 2014, there was a net exceptional pre-tax charge of £44 million (2013: £12 million) to the profit and loss account.

A non-cash pension charge of £36 million (2013: £12 million) arose principally from Heathrow's share of the increase in liabilities under the LHR Airports Limited defined benefit pension scheme since 31 December 2013.

In the three months ended 31 March 2014, Terminal 2 operational readiness costs of £8 million were incurred (2013: nil). These are costs which cannot be capitalised and mainly relate to familiarisation, induction and training activities together with operating costs incurred prior to the start of operations.

2.2.7 Taxation

The tax charge for the Group for the three months ended 31 March 2014 was £4 million based on a loss before tax of £15 million. The tax charge has been calculated by applying the forecast annual effective tax rate for each entity to the results for the three months ended 31 March 2014. The effective tax rate for the period differs from the UK statutory rate of corporation tax of 21.5% due to seasonality and permanent differences mainly arising from non-qualifying depreciation. The effective tax rate for the Group reflects the proportionate contribution of each entity's results in each interim accounting period and will vary where those proportions change.

2.3 Cash flow

2.3.1 Summary cash flow

2.3.2 Cash flow from operating activities

Net cash inflow from continuing operations in the three months ended 31 March 2014 increased 19.6% to £317 million (2013: £265 million) which compares with Adjusted EBITDA of £319 million (2013: £242 million).

2.3.3 Capital expenditure

The most significant areas of capital expenditure at Heathrow were remaining work on Terminal 2 and the new integrated baggage system for Terminal 3.

In the three months ended 31 March 2014, the cash flow impact of capital investment at Heathrow was £271 million (2013: £275 million of which £3 million related to Stansted). Gross balance sheet additions to fixed assets in the period were £336 million, meaning that £65 million was added to capital creditors. This reflects timing differences between work undertaken on assets and supplier payments. The current high level of capital creditors associated with the completion of Terminal 2 is expected to unwind over 2014.

2.3.4 Restricted payments

In the three months ended 31 March 2014, restricted payments of £92 million were made which funded £65 million of the £68 million in quarterly dividends paid to the Group's ultimate shareholders and £27 million of interest payments on the debenture between Heathrow (SP) and Heathrow Finance plc (2013: £450 million including £64 million in quarterly dividends, £51 million to fund interest payments at Heathrow Finance plc and ADI Finance 1 Limited and £300 million related to the sale of Stansted).

2.4 Pension scheme

At 31 March 2014, the LHR Airports Limited defined benefit pension scheme had a deficit of £121 million (31 December 2013: £93 million) as measured under FRS 17, of which £108 million (31 December 2013: £81 million) was attributable to the Group under the Group's shared services agreement with LHR Airports Limited. The increase in the Group's share of the deficit is mainly due to a reduction in the discount rate partially offset by asset returns.

2.5 Recent financing activity

The current focus of the Group's financing activities is to take advantage of attractive financing market conditions to optimise the Group's long-term cost of debt and extend its debt maturity profile. Since the start of 2014, Heathrow has closed a £200 million private placement of index-linked bonds, with three tranches maturing in 2032, 2039 and 2049.

As highlighted last year, the Group expects the scale of its funding requirements over the coming years to be an average of less than £1.5 billion per annum. This reflects a reduced capital programme and continued increases in operating cash flow at Heathrow through the new regulatory period ending in 2018.

The Group's funding target for the remainder of 2014 is in the region of £850 million. Proceeds will be used primarily to repay the €750 million bond maturity in September 2014. With Heathrow's new regulatory period now underway, subject to market conditions, the Group intends to return to the debt capital markets in the coming months.

2.6 Financing position

2.6.1 Consolidated net debt and liquidity at Heathrow (SP) Limited

The analysis below focuses on the Group's external debt and excludes restricted cash and the debenture between Heathrow (SP) and its parent company, Heathrow Finance. It includes all the components used in calculating gearing ratios under the Group's financing agreements including index-linked accretion.

During the three months ended 31 March 2014, the Group's nominal net debt increased 2.4% to £11,529 million from £11,264 million at 31 December 2013.

The Group's nominal net debt at 31 March 2014 comprised £10,819 million under bond issues, £25 million of drawings under the Group's revolving credit facilities, £207 million under other loan facilities, £485 million in index-linked derivative accretion and cash at bank and term deposits of £7 million. Nominal net debt comprised £10,104 million in senior net debt and £1,425 million in junior debt.

The accounting value of the Group's net debt at 31 March 2014 was £10,913 million (31 December 2013: £10,712 million), which includes £8 million of cash on the balance sheet.

The average cost of the Group's external gross debt at 31 March 2014 was 4.64% (31 December 2013: 4.53%), taking into account the impact of interest rate, cross-currency and index-linked hedges but excluding index-linked accretion. Including index-linked accretion, the Group's average cost of debt at 31 March 2014 was 6.02% (31 December 2013: 6.01%).

At 31 March 2014, the Group had approximately £2.1 billion in undrawn loan facilities and cash resources which, together with expected operating cash flow over the period, is expected to provide sufficient liquidity to meet all its obligations in full, including capital investment, debt service costs, debt maturities and distributions, until early 2016.

2.6.2 Consolidated net debt at Heathrow Finance plc

Taking into account the Group's nominal net debt discussed in section 2.6.1, together with £763 million of gross debt and £4 million of cash held at Heathrow Finance, Heathrow Finance's consolidated nominal net debt at 31 March 2014 was £12,288 million, an increase of 2.2% from £12,025 million at 31 December 2013.

2.6.3 Regulatory Asset Base ('RAB')

Heathrow's RAB at 31 March 2014 was £14,853 million compared to £14,585 million at 31 December 2013. RAB figures are utilised in calculating gearing ratios under the Group's financing agreements.

The increase in Heathrow's RAB during the three months ended 31 March 2014 reflected the addition of approximately £340 million in capital expenditure and indexation adjustments of around £80 million. The increases were partially offset by regulatory depreciation of around £150 million.

Of the £5.9 billion capital investment added to the RAB during the Q5 regulatory period, the CAA has disallowed £32 million from being included in the RAB. This will be reflected in RAB figures published for June 2014 onwards.

2.6.4 Net interest payable and net interest paid

In the three months ended 31 March 2014, the Group's net interest payable was £180 million (2013: £606 million) and net interest paid was £197 million (2013: £167 million). A reconciliation from interest payable on the profit and loss account to interest paid on the cash flow statement is provided below.

Underlying net interest payable was £193 million (2013: £194 million) after adjusting for the fair value loss on financial instruments of £28 million (2013: £433 million loss); capitalised interest of £49 million (2013: £34 million) and non-cash amortisation of financing fees, discounts and fair value adjustments of debt of £8 million (2013: £13 million).

The difference between underlying net interest payable and net interest paid is primarily accounted for by non-cash accretion on index-linked instruments of £43 million (2013: £53 million) offset by other movements.

Net interest paid in the period was £197 million (2013: £167 million) of which £170 million (2013: £140 million) was paid in relation to external debt. The increase in net interest paid on external debt mainly reflects timing of coupon payments which fell into April in 2013 and March in 2014. The remaining £27 million (2013: £27 million) of interest paid related to the debenture between Heathrow (SP) and Heathrow Finance.

2.6.5 Financial ratios

The Group and Heathrow Finance continue to operate comfortably within required financial ratios.

At 31 March 2014, the Group's senior (Class A) and junior (Class B) gearing ratios (nominal net debt to RAB) were 68.0% and 77.6% respectively (31 December 2013: 67.6% and 77.2% respectively) compared with trigger levels of 70.0% and 85.0% under its financing agreements. Heathrow Finance's gearing ratio was 82.7% (31 December 2013: 82.4%) compared to a covenant level of 90.0% under its financing agreements.

2.7 Outlook

The Group delivered a strong operational and financial performance in the first quarter of 2014.

Since the CAA published its final decision for the regulatory period that commenced on 1 April 2014, the Group has reassessed the outlook for 2014 including trading in the early months, the impact of the change in the regulatory year-end from 31 March to 31 December and finalising plans to meet the regulatory settlement.

As a result the Group now expects Adjusted EBITDA for 2014 to be slightly higher on a like for like basis to the figure disclosed in the December 2013 investor report which would have been £1,513 million after reclassifying the forecast Terminal 2 operational readiness costs as exceptional items.

As previously highlighted, the phasing of Adjusted EBITDA in 2014 will differ from the normal pattern partly as this year's tariff increase has been deferred from April to July given the proximity of the CAA's final decision to the start of the new regulatory period. Further, Terminal 2 is due to open in June 2014 from when the Group's operating costs will increase. Reflecting these factors, a substantial proportion of 2014's forecast increase in Adjusted EBITDA versus 2013 has been delivered in the first quarter with the remainder expected to fall largely in the second half of the year.

General information and accounting policies

General information

The financial information set out herein does not constitute the Group's statutory financial statements for the year ended 31 December 2013 or any other period. Statutory financial statements for the year ended 31 December 2013 have been filed with the Registrar of Companies on 18 March 2014. The annual financial information presented herein for the year ended 31 December 2013 is based on, and is consistent with, the audited consolidated financial statements of Heathrow (SP) Limited (the 'Group') for the year ended 31 December 2013. The auditors' report on the 2013 financial statements was unqualified, did not contain an emphasis of matter paragraph and did not contain any statements under section 498(2) or (3) of the Companies Act 2006.

Accounting policies

Basis of preparation

The consolidated financial statements of Heathrow (SP) Limited have been prepared under the historical cost convention, as modified by the revaluation of certain tangible fixed assets and financial instruments, in accordance with the Companies Act 2006 and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice). The accounting policies adopted in the preparation of this consolidated financial information are consistent with those applied by the Group in its audited consolidated financial statements for the year ended 31 December 2013 with the exception of tax accounting (see note 5) which is in accordance with the United Kingdom Accounting Standards Board's : 'Half-Yearly Financial Reports'.

Change in accounting policy

For the 31 December 2013 year end financial statements it was considered appropriate to amend the presentation of the net of the interest cost and the expected return on assets relating to the defined benefit pension scheme in the profit and loss account. Previously the amount was presented as a component of employment costs, but it was considered to provide greater clarity and was consequently more appropriate for the amount to be included as a component of interest.

The profit and loss account for the three months ended 31 March 2013 has been restated to reflect this change, increasing employment costs and reducing interest cost by £2 million compared to the amounts previously reported and reducing operating profit to £114 million from £116 million. The impact on the three months ended 31 March 2014 has been to increase employment costs and reduce interest cost and operating profit by £3 million. Similarly the impact on the year ended 31 December 2013 was to increaseemployment costs and reduce interest cost by £7 million. There has been no impact on the balance sheet or cash flows of the Group from this change in presentation.

Discontinued operations

Stansted airport has been classified as discontinued operations due to the completion of its disposal on 28 February 2013.

Since August 2008, HAL and HEX have had an obligation under the SSA, to fund or benefit from their share of the LHR Airports Limited defined benefit pension scheme deficit or surplus and Unfunded Unapproved Retirement Benefit Scheme and Post-Retirement Medical Benefits pension related liabilities. These provisions or assets are based on the relevant share of the actuarial deficit or surplus and allocated on the basis of pensionable salaries. Movements in these provisions or assets are recorded as exceptional items due to their size and nature.

5 Tax (charge)/credit on (loss)/profit on ordinary activities

The tax charge for the three months ended 31 March 2014 results in a negative effective tax rate of 28.8%, reflecting the tax charge arising on ordinary activities of £4 million. The tax charge has been calculated by applying the forecast annual effective tax rate for each entity to the results for the three months ended 31 March 2014. The effective tax rate for the period differs from the UK statutory rate of corporation tax of 21.5% due to seasonality and permanent differences mainly arising from non-qualifying depreciation. The effective tax rate for the Group reflects the proportionate contribution of each entity's results in each interim accounting period and will vary where those proportions change.

For the three months ended 31 March 2013, the effective tax rate was 55.1%, reflecting the tax credit arising on ordinary activities of £108 million.

For the year ended 31 December 2013, the effective tax rate was 8.7%, reflecting the tax charge arising on ordinary activities of £65 million and a tax credit of £28 million due to the reductions in the rate of corporation tax from 23% to 21% from 1 April 2014 and from 21% to 20% from 1 April 2015. These reductions were enacted in the Finance Act 2013 on 17 July 2013 and as a result the Group's deferred tax balances were re-measured during the year ended 31 December 2013 at a rate of 20%.

The Group's disposal of Stansted Airport Limited has no corporation tax charge as it qualifies for the Substantial Shareholding Exemption.
