Trading Statement

Tremor International Ltd (AIM: TRMR), a global leader in video advertising technologies, provides an update on current trading.

The Company's performance during the first quarter of 2021, which historically is the lowest quarter by revenue in the year, is significantly ahead of the same period in 2020, predominantly pre-pandemic. This continued sustainable organic growth is a clear endorsement of Tremor's strategy, executed by the Company's end-to-end technology platform together with strong demand inflow. Therefore, the Company now expects trading for the year ending 31 December 2021 to be significantly ahead of management expectations.

Tremor expects to report net revenue* of $55 million to $60 million, an increase of 71%-87% (Q1 2020: $32.1 million), and Adjusted EBITDA of $25 million to $28 million an increase of 46-51 times, (Q1 2020: $0.5 million), in the first quarter of the financial year. Programmatic net revenues are expected to grow by 84%-95% in Q1 2020.

This positive momentum continues to be underpinned by the successful execution of the Company's strategy, which focuses on video and data, with Tremor's core solutions of Connected TV, Private Marketplaces and its self-serve platform continuing to achieve significant traction.

*Net Revenue = Gross Revenue less media cost.
