PROPOSED PLACING OF ORDINARY SHARES IN AUCTION TECHNOLOGY GROUP PLC ("ATG" OR THE "COMPANY") REPRESENTING APPROXIMATELY 10% OF THE COMPANY'S ISSUED SHARE CAPITAL

1 September 2021

TA Associates and ECI Partners announce their intention to sell ordinary shares of 0.01 pence each (the "Placing Shares") representing approximately 10% of the Company's issued share capital (in aggregate) through a placing to institutional investors (the "Placing").

The Placing Shares will be sold by TA Associates through its sub-funds TA XIII-A, L.P., TA XIII-B, L.P., TA Investors XIII, L.P., TA Investors IV EU AIV, L.P. and TA Subordinated Debt Fund IV, L.P., and by ECI partners through ECI 11 L.P. (together, the "Sellers").

The Sellers currently own in aggregate approximately 33.8% of the Company's issued share capital, corresponding to 40,515,747 shares, of which approximately 25.9% is ultimately owned by TA Associates and 7.8% by ECI Partners.

The price per Placing Share will be determined by way of an accelerated bookbuilding process to institutional investors. The bookbuilding period will commence immediately following this announcement, and may close at any time on short notice. J.P. Morgan Securities plc ("J.P. Morgan") and Numis Securities Limited ("Numis") (together the "Joint Global Coordinators" or the "Banks") are acting as joint global coordinators and joint bookrunners in connection with the Placing.

The Sellers will be locked up in respect of their residual holdings until 90 days post settlement of the Placing, subject to customary exceptions.

The final number of Placing Shares to be placed will be agreed by the Joint Global Coordinators and the Sellers at the close of the bookbuilding process, and the results of the Placing will be announced as soon as practicable thereafter.

ATG will not receive any proceeds from the Placing.
