Tremor International Ltd

("Tremor" or the "Company")

Intent to File a Motion with Israeli Court Seeking Authorisation for Share Repurchase Program

Tremor International Ltd. (AIM/NASDAQ: TRMR) ("Tremor" or the "Company"), a global leader in data-driven video and Connected TV ("CTV") advertising technology, offering a unified platform that enables advertisers to optimize campaigns and media companies to maximize inventory yield, announced that it intends to file a motion with the Israeli court, as required by Israeli law, seeking approval to authorise the Company to repurchase a further $20 million of its Ordinary Shares from time to time over a term commencing upon the date of the court's approval of the motion, and ending approximately six months thereafter.

Being an Israeli company, Israeli law requires Tremor to obtain Israeli court approval for the share repurchase program based on IFRS net income thresholds, even though Tremor has sufficient cash reserves and cash flow to fund the proposed share repurchase program.

If and when obtained, the Israeli court approval will provide Tremor with the right to repurchase its shares but does not require the Company to acquire any or a specific number of shares.

The Company expects the Israeli court to take approximately 45 - 60 days to reach a decision and will provide an update if and when court approval is obtained.

Change of Name of Nominated Adviser and Broker

The Company also announces that its Nominated Adviser and Broker has changed its name to Cavendish Capital Markets Ltd following completion of its own corporate merger.
