BRITISH TELECOMMUNICATIONS PUBLIC LIMITED COMPANY ANNOUNCES TENDER OFFERS

British Telecommunications public limited company (the "Offeror") announces that it is inviting holders of its outstanding EUR 650,000,000 0.500 per cent. Notes due 12 September 2025 (ISIN: XS2051494222) (the "2025 Notes") and EUR 1,300,000,000 1.750 per cent. Notes due 10 March 2026 (ISIN: XS1377679961) (the "2026 Notes" and together with the 2025 Notes, the "Notes" and each a "Series") to tender their Notes for purchase by the Offeror for cash in an aggregate nominal amount of up to the Maximum Acceptance Amount (as defined below), subject to pro rata scaling, if applicable, and subject to applicable law and regulation and the offer and distribution restrictions and the satisfaction or waiver of the New Financing Condition (as defined below) and the other conditions described in the tender offer memorandum dated 13 June 2024 (the "Tender Offer Memorandum") (each such invitation an "Offer" and together the "Offers").

The Offers are made on the terms and subject to the conditions (including satisfaction or waiver of the New Financing Condition) contained in the Tender Offer Memorandum and should be read in conjunction with the Tender Offer Memorandum. Capitalised terms used but not otherwise defined in this announcement shall have the meaning given to them in the Tender Offer Memorandum.

Rationale for the Offers

The rationale for the Offers is to optimise the liquidity and debt maturity profile of the Offeror and BT Group plc. Notes purchased by the Offeror pursuant to the Offers will be cancelled and will not be re-issued or re-sold. Notes which have not been validly submitted and accepted for purchase pursuant to the Offers will remain outstanding.

Details of the Offers

The submission of a valid Tender Instruction through the Clearing Systems will be irrevocable except in the limited circumstances in which the revocation of a Tender Instruction is specifically permitted in accordance with the terms of the Offers.

Purchase Price

The 2025 Notes Purchase Price will be calculated at or around the Pricing Time as the price (expressed as a percentage of the nominal amount of the 2025 Notes accepted for purchase pursuant to the 2025 Notes Offer and rounded to the third decimal place, with 0.0005 being rounded upwards) equal to (a) each remaining payment of principal and interest on the 2025 Notes up to and including 12 September 2025 (being the maturity date of the 2025 Notes), discounted to the Settlement Date at a discount rate equal to the 2025 Notes Repurchase Yield (being the sum of the 2025 Notes Interpolated Mid-Swap Rate and the 2025 Notes Fixed Spread), less (b) the Accrued Interest in respect of the 2025 Notes.

The 2026 Notes Purchase Price will be calculated at or around the Pricing Time as the price (expressed as a percentage of the nominal amount of the 2026 Notes accepted for purchase pursuant to the 2026 Notes Offer and rounded to the third decimal place, with 0.0005 being rounded upwards) equal to (a) each remaining payment of principal and interest on the 2026 Notes up to and including 10 March 2026 (being the maturity date of the 2026 Notes), discounted to the Settlement Date at a discount rate equal to the 2026 Notes Repurchase Yield (being the sum of the 2026 Notes Interpolated Mid-Swap Rate and the 2026 Notes Fixed Spread), less (b) the Accrued Interest in respect of the 2026 Notes.

The determination of the 2025 Notes Purchase Price and the 2026 Notes Purchase Price will, in the absence of manifest error, be final and binding on all parties.

Tender Consideration

The consideration (the "Tender Consideration") payable, subject to satisfaction or waiver of the New Financing Condition, on the Settlement Date to a Qualifying Holder whose Notes are validly Offered for Sale and accepted for purchase by the Offeror pursuant to the Offers will be an amount in EUR equal to the sum of: (i) the product of (x) the relevant Purchase Price and (y) the nominal amount of the relevant Notes; and (ii) the relevant Accrued Interest Amount in respect of such Notes, rounded, if necessary, to the nearest EUR 0.01, with EUR 0.005 being rounded upwards.

Maximum Acceptance Amount and Acceptance on a Pro-Rata Basis

The Offeror proposes to accept Notes for purchase up to the Maximum Acceptance Amount on the terms and subject to the conditions (including the satisfaction or waiver of the New Financing Condition) contained in the Tender Offer Memorandum (although the Offeror reserves the right, in its sole and absolute discretion and for any reason, to increase or decrease the Maximum Acceptance Amount).

Until the Offeror announces the final aggregate nominal amount of each Series (if any) accepted for purchase, no assurance can be given that any Notes validly Offered for Sale pursuant to the Offers will be accepted. Even if the New Financing Condition is satisfied, the acceptance of any Notes validly Offered for Sale is at the sole and absolute discretion of the Offeror and the Offeror reserves the absolute right not to accept any Notes validly Offered for Sale pursuant to the Offers. The Offeror will determine the allocation of the aggregate nominal amount accepted for purchase pursuant to the Offers among each Series (the "Series Acceptance Amounts" and each, a "Series Acceptance Amount") in its sole and absolute discretion and may purchase considerably less (or none) of one Series than of another Series.

If the Offeror decides to accept Notes of any Series for purchase pursuant to the Offers and in the event that valid Tender Instructions are received in respect of an aggregate nominal amount of a Series which is greater than the relevant Series Acceptance Amount, such Tender Instructions will be accepted on a pro rata basis as further set out in the Tender Offer Memorandum such that the aggregate nominal amount of such Series accepted for purchase is no greater than the relevant Series Acceptance Amount.

New Notes and New Financing Condition

The Offeror announced on 13 June 2024 its intention, subject to market conditions, to issue a new series of euro-denominated fixed rate notes (the "New Notes"), unconditionally and irrevocably guaranteed by BT Group plc. Whether the Offeror will accept for purchase any Notes validly tendered in the Offers is subject, without limitation, to (unless such condition is waived by the Offeror in its sole and absolute discretion) the successful completion (in the sole determination of the Offeror) of the issue of the New Notes (the "New Financing Condition").

Allocation of the New Notes

When considering allocation of the New Notes, the Offeror intends to give preference to those Holders who, prior to such allocation, have validly tendered (or have given a firm indication to the Offeror or any Dealer Manager that they intend to tender) their Notes pursuant to the Offers. Therefore, a Holder who wishes to subscribe for New Notes in addition to tendering its Notes for purchase pursuant to the Offers may be eligible to receive, at the sole and absolute discretion of the Offeror, priority in the allocation of the New Notes, subject to the issue of the New Notes and such Holder making a separate application for the purchase of such New Notes to a Dealer Manager (in its capacity as a joint lead manager of the issue of the New Notes) in accordance with the standard new issue procedures of such Dealer Manager. However, the Offeror is not obliged to allocate the New Notes to a Holder who has validly tendered or indicated a firm intention to tender the Notes pursuant to the Offers and, if New Notes are allocated, the nominal amount thereof may be less or more than the nominal amount of Notes tendered by such Holder and accepted by the Offeror pursuant to the Offer. Any such allocation will also, among other factors, take into account the minimum denomination of the New Notes (being EUR 100,000 in the case of the New Notes).

All allocations 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. In the event that a Holder validly tenders Notes pursuant to the Offer, such Notes will remain subject to such tender and the conditions of the Offers as set out in the Tender Offer Memorandum irrespective of whether that Holder receives all, part or none of any allocation of New Notes for which it has applied.

Holders should note that the pricing and allocation of the New Notes are expected to take place prior to the Expiration Time and any Holder that wishes to subscribe for New Notes in addition to tendering existing Notes for purchase pursuant to the Offers should therefore provide, as soon as practicable, and prior to the allocation of the New Notes, to any Dealer Manager any indications of a firm intention to tender Notes for purchase pursuant to the Offers and the quantum of Notes that it intends to tender in order for this to be taken into account as part of the New Notes allocation process.

Expected Timetable of Events

This is an indicative timetable and is subject to the right of the Offeror to extend, re-open, amend and/or terminate the Offers (subject to applicable law and as provided in the Tender Offer Memorandum). Announcements and notices to be given to Qualifying Holders in connection with the Offers will be made (i) by publication via the Regulatory News Service and (ii) by the delivery of notices to the Clearing Systems for communication to Direct Participants. Announcements may also be made by issue of a press release to one or more Notifying News Service(s). Copies of all such announcements, press releases and notices can also be obtained upon request from the Tender Agent.
