HELIOS TOWERS ANNOUNCES OFFER TO PURCHASE FOR CASH ANY AND ALL OF THE OUTSTANDING 7.000% SENIOR NOTES DUE 2025

May 20, 2024 - HTA Group, Ltd (the "Offeror"), an indirect wholly owned subsidiary of Helios Towers plc (the "Company"), announces the launch of its offer to purchase for cash any and all of the 7.000% Senior Notes due 2025 issued by the Offeror and guaranteed on a senior basis by the Company and certain of its direct and indirect subsidiaries (the "Notes"), upon the terms and subject to the conditions set forth in the offer to purchase dated May 20, 2024 (the "Offer to Purchase"), including, but not limited to, the Financing Condition (as defined below) (the "Tender Offer"), which is available, subject to eligibility and registration, on the tender offer website (the "Tender Offer Website"): https://projects.morrowsodali.com/HTA.

The Offeror is making the Tender Offer, in combination with the New Notes Offering (as defined below), as a way of managing the financial liabilities and cost of debt financing of the Company and its consolidated subsidiaries. Subject to the minimum denomination of the Notes, the "Purchase Price" per U.S.$1,000 principal amount of Notes validly tendered and accepted for purchase pursuant to the Tender Offer will be U.S.$1,000.

The Tender Offer will expire at 5:00 p.m., New York City time, on May 30, 2024, unless extended or earlier terminated (such time and date, as the same may be extended, the "Expiration Deadline"). Holders who tender their Notes may withdraw such Notes at any time prior to 5:00 p.m., New York City time, on May 30, 2024 (such time and date, as the same may be extended).

The following table sets forth certain details of the Tender Offer:

In addition to the Purchase Price, all holders of Notes accepted for purchase will also receive accrued and unpaid interest on such Notes, rounded to the nearest U.S.$0.01, with half a cent rounded upwards, per U.S.$1,000 principal amount of Notes, from and including the last interest payment date up to, but not including, the Settlement Date (the "Accrued Interest").

Concurrently with the announcement of the Tender Offer, the Offeror announced an offering of new U.S. dollar-denominated senior notes (the "New Notes"), subject to market conditions (the "New Notes Offering"). Subject to the successful closing of the New Notes Offering, a portion of the proceeds from the New Notes Offering is expected to fund the Tender Offer. This announcement does not constitute an offer to sell or a solicitation of an offer to buy any New Notes. No assurances can be given that the Offeror will complete the New Notes Offering. The Tender Offer is conditioned upon, among other things, the successful completion (in the sole determination of the Offeror) of the New Notes Offering (the "Financing Condition").

Following completion of the Tender Offer and provided the Financing Condition is met, the Offeror intends to redeem any remaining outstanding Notes pursuant to the terms of the indenture governing the Notes dated June 18, 2020 (as amended or supplemented, the "Indenture"). It is expected that such redemption would be completed on June 18, 2024, and would be at a price equal to 100% of the principal amount of each Note redeemed, plus accrued and unpaid interest (if any) to the applicable date of redemption. Nothing in this announcement constitutes a redemption notice.

The Offeror intends, in connection with the allocation of New Notes in the New Notes Offering, to consider among other factors whether or not the relevant investor seeking an allocation of the New Notes has validly tendered or indicated to the Offeror or the Dealer Managers a firm intention to tender any Notes it holds pursuant to the Tender Offer and, if so, the aggregate principal amount of such Notes tendered or intended to be tendered by such investor. When determining allocations of the New Notes, the Offeror intends to give some degree of preference to such investors. However, the Offeror will consider various factors in making allocation decisions and is not obliged to allocate any New Notes to an investor who has validly tendered or indicated to the Offeror or the Dealer Managers a firm intention to tender any Notes it holds pursuant to the Tender Offer and if allocated, the allocated amount may be more or less than the amount tendered and accepted to purchase.

Any potential allocation of the New Notes, while being considered by the Offeror as set out above, will be made in accordance with customary new issue allocation processes and procedures following the completion of the book building process for the offering of the New Notes and will be made at the sole discretion of the Offeror. In the event that a Holder validly tenders Notes pursuant to the Tender Offer, such Notes will remain subject to such tender and the conditions of the Tender Offer as set out in this Offer to Purchase irrespective of whether that Holder receives all, part or none of any allocation of New Notes for which it has applied.

The New Notes are expected to price and be allocated prior to the Expiration Deadline and as such, investors should contact either the Offeror or any of the Dealer Managers to provide firm indications that they intend to tender Notes pursuant to the Tender Offer as soon as possible, using the contact details in this announcement.

Guaranteed Delivery (DTC only)

If a Holder desires to tender the Notes held through DTC and if time will not permit such Holders to comply with the procedures of the relevant Clearing System to submit a valid tender instruction before the Expiration Deadline, the Holder may nevertheless tender the Notes, provided that the Holder delivers the Notice of Guaranteed Delivery and satisfies all other conditions set forth in the Offer to Purchase.

Significant Events, Dates and Times

Subject to applicable law and the terms and conditions of the Offer to Purchase, the Offeror may terminate the Tender Offer, waive any or all of the conditions of the Tender Offer prior to the Expiration Deadline, extend the Expiration Deadline or amend the terms of the Tender Offer.

None of the Offeror, the guarantors of the Notes, the dealer managers, the information and tender agent or the trustee (nor any director, officer, employee, agent or affiliate of, any such person) makes any recommendation whether holders should tender or refrain from tendering Notes in the Tender Offer. Holders must make their own decision as to whether to tender Notes and, if so, the principal amount of the Notes to tender. Holders are urged to evaluate carefully all information in the Offer to Purchase, consult their own investment and tax advisers and make their own decisions whether to tender Notes in the Tender Offer, and, if so, the principal amount of Notes to tender.
