Transaction in Own Shares

Share buy-back programme

On 19 October 2018, Man Group plc (the "Company") announced its intention to repurchase up to $100 million of shares (the "Programme"). The Board today announces that, as the first tranche of this share repurchase (the "Initial Programme"), it has entered into an irrevocable, non-discretionary arrangement with J. P. Morgan Securities plc to repurchase, on its behalf, ordinary shares in the Company up to a maximum consideration of $50 million. The Initial Programme will be subject to certain pre-set parameters and will be executed during the period from 22 October 2018 up to and including 31 March 2019 (the "Engagement Period"), including during any closed or prohibited period of the Company which may fall during the Engagement Period. The purpose of the Initial Programme is to reduce the share capital of the Company (any shares repurchased for this purpose will be cancelled) and to enable the Company to meet obligations arising from employee share option programmes, or other allocations of shares to employees of the Company or to members of the administrative, management or supervisory bodies of the Company or an associate of the Company (any shares repurchased for this purpose will be held in treasury). The number of shares to be acquired is estimated to be around 27.1 million* based on the prevailing share price and Sterling to US Dollar exchange rate as at the date immediately prior to this announcement.

A proportion of shares purchased under the Initial Programme will be held in treasury and the remaining shares will be cancelled.

Any shares repurchased under the Initial Programme will be effected in accordance with the Company's general authority to repurchase shares and Chapter 12 of the UKLA Listing Rules and will be discontinued in the event the Company ceases to have the necessary general authority to repurchase ordinary shares.

Any further tranches of the share repurchase, which may be conducted after completion of the Initial Programme, will be announced in due course.
