Launch of up to $75 million Share Buyback

London, 6 November 2025: Helios Towers plc ("Helios Towers", "the Group" or "the Company"), the independent mobile tower company, announces that its Board has approved a return of up to $75 million to shareholders by the end of 2026, to be implemented through a share buyback programme to purchase ordinary shares in the Company with a nominal value of £0.01 each (the "Buyback Programme").

The Buyback Programme forms part of the Company's disciplined capital allocation framework, reflecting Helios Towers' strong balance sheet, cash generation and continued confidence in its long-term growth prospects.

An initial tranche of $25 million will commence on 6 November 2025, under a non-discretionary agreement with Jefferies International Limited ("Jefferies"). Jefferies will act as principal and make trading decisions independently of the Company, in accordance with pre-set parameters.

It is anticipated that additional non-discretionary arrangements with other brokers in respect of the second, and any further tranches, of the Buyback programme will be entered into in due course.

All ordinary shares repurchased under the Buyback Programme will be cancelled. The purpose of the Buyback Programme is to return surplus capital to shareholders and optimise the Company's capital structure.

The Buyback Programme will take place within the limitations of the authority granted by shareholders to the Board of the Company at its annual general meeting held on 15 May 2025 (and as such authority may be renewed and/or amended). The maximum number of ordinary shares that can be purchased by the Company under the Buyback Programme pursuant to the authority granted by shareholders is 105,270,000.

The timing and total value of share repurchases will depend on market conditions, share price, trading volumes, and other relevant factors. The Buyback Programme is intended to be conducted in accordance with the UK Market Abuse Regulation (EU) No. 596/2014 (as incorporated into UK law), and the Commission Delegated Regulation (EU) 2016/1052 (also as in force in the UK, from time to time, including, where relevant, pursuant to the UK's European Union (Withdrawal) Act 2018 and the Market Abuse (Amendment) (EU Exit) Regulations 2019) as well as applicable laws and the regulations of the UK Financial Conduct Authority (including Chapter 9 of the Listing Rules).

Helios Towers will make further announcements in due course following the buyback of shares. Any repurchase of shares will be announced no later than 7:30am on the business day following the calendar day on which the repurchase occurred.

The execution of the Buyback Programme may be augmented by the purchase of Shares by way of block trades. The maximum number of shares which can be repurchased by the Company under the Buyback Programme will be reduced by the corresponding amount of capital returned through block trades.

Helios Towers expects to complete the Buyback Programme by the end of 2026 and will make further announcements as required in accordance with applicable regulations. Note there is no guarantee that the Buyback Programme will be implemented in full.
