Velocys plc

("Velocys" or the "Company")

Leadership update

Velocys plc (VLS. L), the sustainable fuels technology company, announces the following changes to its management team.

Management Team

Andy Bensley has joined Velocys as the Global Head of Business Development and Technology delivery. He comes with 35 years of international experience in senior corporate, functional leadership and project delivery roles in both major IOC's and EPC contractor organisations, including positions at Bechtel, Shell, SK E&C and Eni.

Heinz Robota, VP Technology, will be retiring from his role after 10 years at Velocys and will be replaced by Dawid Duvenhage who joined the Company in November 2021 with the responsibility for Velocys' catalysis division. Heinz has led the catalysis efforts from R&D into commercial demonstrated status of Velocys' super active FT catalyst. Following an initial career as a chemist and chief scientist, Dawid has over 30 years' experience in catalyst development, scale-up and commercialisation.

Heinz has agreed to continue to support Velocys as a member of our Senior Scientific Advisory Board.

Directorate Change

Andrew Morris, CFO, has advised the Board of his intention to leave Velocys in order to pursue other career opportunities. The intention is for Andrew to step down as CFO and Board Director during Q2 2022. Further updates will be made in due course.

Andrew has been with Velocys since 2017 when he joined the board as a Non-Executive Director and Chairman of the Company's Audit and Risk Committee. As part of an Executive management change in 2018, Andrew stepped in as CFO of the Company that year. He has played a key role in strengthening and consolidating the finance function of the Company. The Board is grateful for Andrew's service and his commitment, and he will leave with Velocys' very best wishes for his future endeavours.

Phil Holland, Chairman of Velocys, said:

"The Board would like to convey its gratitude to Andrew for his role in establishing a strong finance function within Velocys, and for his ongoing support over the coming months. We wish Andrew the very best in his pursuit of new opportunities and the next chapter of his professional career.

"I, along with Henrik Wareborn and the Board, welcome the appointment of Andy Bensley, who will accelerate the commercialisation of the Velocys technology with a focus on strengthening the global client pipeline.

"Our sincere appreciation goes to Heinz who will be retiring next month. He has held an integral and leading role in catalysis technology development, and Dawid Duvenhage has picked up the reins to continue Velocys' critical technology work.

"Velocys is well positioned to deliver substantial growth by providing our clients with our sustainable synthetic fuels technology enabling commercial scale production of high energy density fuels with negative carbon intensity."
