Exercise of Option over Altalto Project Site

Velocys plc (AIM: VLS), the sustainable fuels technology company, today announces that further to the announcement of 25 November 2021 and following completion of the fundraising, Altalto Immingham Ltd ("Altalto") (a subsidiary of Velocys) has exercised an option agreement to acquire Rula Developments (Immingham) Limited ("RDIL") with an initial part-payment of £2.5 million. RDIL owns the site of the proposed Altalto project, near Immingham in North East Lincolnshire, which is being jointly developed by British Airways PLC ("BA") and Velocys.

Pursuant to the agreement, the total consideration to acquire the site is being satisfied by a £2.5 million part-payment, funded through an inter-company loan from Velocys to Altalto. A further deferred consideration amount of up to £8.5 million is payable by 30 September 2022. As previously announced, Velocys is discussing the onward purchase of RDIL (and subsequent grant back to Altalto of a future option to purchase RDIL within 3 years) with a third party with the intention that the purchase price for RDIL paid by the third party will cover the remaining consideration payable by Altalto in 2022.

Detailed engineering for the Altalto project is expected to commence in 2023. Financial close is expected in 2024, with construction of the plant being targeted to commence in 2024 and to be completed by mid-2026, following which commissioning and start-up will commence, with full scale commercial operation expected in 2027.
