This announcement contains inside information for the purposes of article 7 of the Market Abuse Regulations (EU) 596/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018. 12 June 2021 Esken Limited (‘Esken’ or ‘the Group’) Update on Stobart Air; Potential strategic partnership for LSA; and funding and trading update Esken, the aviation and energy infrastructure group, issues the following update ahead of publishing its preliminary results for the year ended 28 February 2021 due by the end of June. Stobart Air and Carlisle Lake District Airport (together ‘the transactions’) Esken is providing an update on the sale of Stobart Air (‘SA’) and Carlisle Lake District Airport (‘CLDA’) to Ettyl Limited (‘Ettyl’) under the conditional contracts entered into on 20 April 2021. On 28 May 2021 and as reported to the market, Ettyl advised that its original funding package to support the transaction was no longer available and that it was in discussions on alternative funding options. It is now clear that Ettyl is unable to conclude the transactions on the original terms or to obtain an alternative funding package within the required timescale. Esken has therefore exercised its right to terminate the contracts for the transactions with immediate effect. In the absence of any alternative purchasers or sources of funding for the SA business within the timescales required, Esken has advised the Board of SA that it will not continue to provide financial support to the business going forward. As a result of this the Board of SA has terminated its franchise agreement with Aer Lingus, will cease trading and is taking steps to appoint a liquidator. The Board of Esken has undertaken certain contingency planning measures and has agreed in response to these developments that it will continue to fund the lease obligations on the 8 ATR aircraft through to termination of the leases in April 2023 under the terms of its pre- existing guarantee. Esken confirms that it will take immediate steps to seek sublease arrangements for the aircraft with alternative operators to mitigate the impact on the Group. Esken also remains responsible for certain obligations to Aer Lingus under the franchise agreement which were also the subject of a pre-existing guarantee and have become payable following termination of the franchise agreement. These obligations and the guarantees entered into in early 2017 were the reason that the Group reacquired the airline and its related leasing company in April 2020. This enabled the Group to manage and seek to mitigate the impact of these liabilities following the administration of Connect Airways Limited. In the announcement on 20 April 2021, Esken set out the cash flow impact on the Group on the assumption that the transactions concluded. The following table reflects the amended position over the period to the end of the leases assuming that the Group is unable to sublease the aircraft. FY22 FY23 FY24 £m £m £m Cash outflow reported previously 16 9 24 Additional cash impact arising from liquidation 18 13 2 Total Cash outflow 34 22 26 Since April 2020 Esken has taken all steps to minimise the cash requirement of SA while seeking to find a purchaser recognising the importance of the airline to connectivity between the UK & Ireland, the 480 jobs involved and the fact that a sale would be a better outcome for shareholders. Esken has been successful in reducing the impact of its pre-existing obligations and in agreeing terms under which it has control of residual obligations through to expiry. However, the continuing impact of the pandemic which has resulted in almost no flying since April 2020 and the decision taken by Aer Lingus to award preferred bidder status to another party for the franchise agreement beyond its expiry in December 2022 significantly hampered the exhaustive steps taken to secure a future for the business and its staff. Esken will retain the ownership of CLDA rather than it being sold for £15 million (reflected in the cash impact above) but will actively explore strategic options for the use of this asset in discussion with stakeholders including potential alternative commercial opportunities for the airport. Strategic Update The impact of the pandemic has been both greater and over a longer period than anticipated at the time of the capital raise in June 2020. This has led the Board to undertake a further review of the strategy and the medium-term funding requirements for the Group. This concluded that the Group holds two attractive businesses which can generate significant value for shareholders as markets recover post COVID-19. The key strategic objective will therefore be to drive shareholder value from these assets with any decision on the realisation of value being deferred until the businesses recover fully from the pandemic and become mature cash generative business units. While it was previously intended at the time of the capital raise to seek to monetise the Energy business by June 2022, the Board has concluded that this is not the right option for shareholder value. Stobart Energy is a recovering cash generative business with a strong market position and long-term supply contracts. It is anticipated that financial performance will return to pre COVID-19 run rate levels in the current financial year. Opportunities are being explored for additional supply contracts and to broaden the base of the market offering within the energy from waste space where existing operational expertise can be applied. The business offers the opportunity to generate returns from an asset with infrastructure characteristics and a compelling environmental benefit by recycling waste wood to produce energy rather than it going to landfill. In the Aviation business the prime asset is London Southend Airport (‘LSA’) which prior to the pandemic offered passenger services to over 40 destinations to a market of c.8 million people living within one hour travel time to the Airport. Whilst aviation has been one of the hardest hit sectors by the pandemic the fundamental long term value drivers of the Airport remain sound. This has been recognised through strategic partnership discussions in relation to LSA which are covered below. Esken will continue to invest in the infrastructure of the Airport in step with passenger demand recovery allowing LSA to meet the needs of airline partners for an efficient cost effective London airport and offering a safe and enjoyable passenger experience. In addition there is an opportunity to develop the logistics offering both with the existing global logistics partner and other related businesses. Given the award of the Thames Freeport status in the Estuary and proximity to East London, the Airport is well placed to capitalise on accelerated airfreight growth and movements. In line with the previously stated strategy Esken will actively look to exit from all other non- core infrastructure assets owned by the Group having a net book value of c. £39 million at 28 February 2021. When this process is complete Esken will become a focussed Group with two operating businesses. Strategic Partnership for LSA Over the last nine months Esken has been in discussions with a strategic financial partner in relation to the development of LSA as aviation recovers from the pandemic. This partner has significant investment experience in the airport sector globally and will deploy its resources alongside the operational management team at LSA through the COVID-19 recovery phase and future development of the Airport. Esken is now in the final stages of agreeing the documentation for a strategic funding transaction into LSA which would release significant liquidity into the Group while underpinning the funding requirement of the Airport in the medium term. The transaction would be conditional on obtaining shareholder approval. Further details are expected to be announced at the time of the issue of the full year results anticipated by the end of June. Esken nevertheless cautions that no guarantees can be given at this stage that the transaction will be forthcoming. Funding and liquidity update The Group raised £100 million by way of a capital raise in June 2020 together with additional bank facilities of £40 million (“Facility B”) to enable Esken to navigate the impact of the pandemic expected at that time whilst maintaining the operational integrity of its core businesses. The Group’s bank facilities totalling £120 million expire at the end of January 2022 and Esken has been in continuing dialogue with its banks in relation to the repayment of these facilities as well as its medium term funding requirements to meet its ongoing working capital needs. It was a term of Facility B that in order to continue to draw on that facility Esken must satisfy the banks as to its ability to repay the facilities by the due date. The Group has drawn £10 million of its £40 million additional facility but the drawing of any amounts under this facility in excess of £15 million beyond 30 June 2021 is subject to certain conditions. Esken is currently in discussions with its banks in relation to the satisfaction and/or waiver of such conditions in order to ensure continued access to the facilities. The strategic funding proposal in relation to LSA would, if completed, enable Esken to repay the outstanding bank facilities and would significantly reduce the funding requirement of the business to underpin its business plan and meet its legacy obligations and working capital needs. Esken is, and will be, in discussions with its banks and other stakeholders in relation to this requirement, including potentially a modest equity issue on an accelerated basis and expects to conclude these discussions prior to the issue of its financial results for the year to 28 February 2021.
