Fixed Rate Notes due 2025 (ISIN: XS1769818227) ((£300,000,000 of which were issued on 14 February 2018, £50,000,000 of which were issued on 19 September 2018 and £100,000,000 of which were issued on 28 January 2019)) (the Bonds) to tender their Bonds for purchase by the Company for cash (the Offer). The Bonds are guaranteed by United Utilities Water Limited (the Parent).

The Offer is being made on the terms and subject to the conditions contained in the tender offer memorandum dated 15 March 2024 (the Tender Offer Memorandum), prepared by the Company, and is subject to the offer restrictions set out below and as more fully described in the Tender Offer Memorandum.

Capitalised terms used in this announcement but not defined have the meanings given to them in the Tender Offer Memorandum.

Summary

A summary of certain terms of the Offer appears below:

Rationale for the Offer

The Offer is designed to proactively manage the Company's debt maturity profile and to provide liquidity to current Bondholders. Any Bonds purchased by the Company pursuant to the Offer will be cancelled and will not be reissued or resold.

Purchase Price and Accrued Interest

The Company will pay for any Bonds validly tendered and accepted for purchase by the Company pursuant to the Offer a purchase price for such Bonds (the Purchase Price) to be determined at or around 12.00 p.m. (London time) on 22 March 2024 (the Pricing Time) in the manner described in the Tender Offer Memorandum by reference to the annualised sum (such sum, the Purchase Yield) of:

a)            the purchase spread of 45 bps (the Purchase Spread); and

b)            the Benchmark Security Rate.

The Purchase Price will be determined in accordance with market convention and expressed as a percentage of the nominal amount of the Bonds accepted for purchase pursuant to the Offer (rounded to the nearest 0.001 per cent., with 0.0005 per cent. rounded upwards) and is intended to reflect a yield to maturity of the Bonds on the Settlement Date based on the Purchase Yield. Specifically, the Purchase Price will equal (a) the value of all remaining payments of principal and interest up to and including the scheduled maturity date, discounted to the Settlement Date at a discount rate equal to the Purchase Yield, minus (b) any Accrued Interest.

The Company will also pay an Accrued Interest Payment in respect of any Bonds accepted for purchase pursuant to the Offer.

Maximum Acceptance Amount and Final Acceptance Amount

If the Company decides, in its sole and absolute discretion, to accept any validly tendered Bonds for purchase pursuant to the Offer, the Company currently proposes that the aggregate nominal amount of the Bonds that it will accept for purchase pursuant to the Offer will be no greater than £200,000,000 (the Maximum Acceptance Amount), although the Company reserves the right, in its sole and absolute discretion, to accept less or more than the Maximum Acceptance Amount, or to accept none of such Bonds, for purchase pursuant to the Offer (the final aggregate nominal amount of Bonds accepted for purchase pursuant to the Offer being the Final Acceptance Amount).

Scaling

If the Company decides to accept any validly tendered Bonds for purchase pursuant to the Offer and the aggregate nominal amount of Bonds validly tendered for purchase is greater than the Final Acceptance Amount, the Company intends to accept such Bonds for purchase on a pro rata basis such that the aggregate nominal amount of Bonds accepted for purchase pursuant to the Offer is no greater than the Final Acceptance Amount, as further discussed in the Tender Offer Memorandum.

Announcements

The Company intends to announce, prior to the Pricing Time, the aggregate nominal amount of Bonds validly tendered pursuant to the Offer, together with a non-binding indication of the level at which it expects to set the Final Acceptance Amount and indicative details of any Scaling Factor applicable to valid tenders of Bonds that will be applied in the event that the Company decides to accept valid tenders of Bonds pursuant to the Offer.

The Company will then announce, as soon as reasonably practicable after the Pricing Time, its decision of whether to accept valid tenders of Bonds pursuant to the Offer and, if so accepted, the Final Acceptance Amount, the Benchmark Security Rate, the Purchase Yield, the Purchase Price and any Scaling Factor that will be applied to the Bonds, as applicable.

Tender Instructions

In order to participate in, and be eligible to receive the Purchase Price and Accrued Interest Payment pursuant to the Offer, Bondholders must validly tender their Bonds by delivering, or arranging to have delivered on their behalf, a valid Tender Instruction that is received by the Tender Agent by 4.00 p.m. (London time) on 21 March 2024, unless extended, re-opened, amended and/or terminated as provided in the Tender Offer Memorandum (the Expiration Deadline).

Bondholders are advised to check with any bank, securities broker or other intermediary through which they hold Bonds when such intermediary would need to receive instructions from a Bondholder in order for that Bondholder to be able to participate in, or (in the limited circumstances in which revocation is permitted) revoke their instruction to participate in, the Offer by the deadlines specified in the Tender Offer Memorandum. The deadlines set by any such intermediary and each Clearing System for the submission and withdrawal of Tender Instructions will be earlier than the relevant deadlines specified in this announcement and the Tender Offer Memorandum.

Tender Instructions will be irrevocable except in the limited circumstances described in the Tender Offer Memorandum.

Tender Instructions must be submitted in respect of a minimum nominal amount of the Bonds of no less than £100,000, being the minimum denomination of the Bonds, and may thereafter be submitted in integral multiples of £1,000. A separate Tender Instruction must be completed on behalf of each beneficial owner.

Indicative Timetable for the Offer

This is an indicative timetable and may be subject to change. Bondholders are advised to check with any bank, securities broker or other intermediary through which they hold Bonds when such intermediary would need to receive instructions from a Bondholder in order for that Bondholder to be able to participate in, or (in the limited circumstances in which revocation is permitted) revoke their instruction to participate in the Offer by the deadlines set out above and in the Tender Offer Memorandum. The deadlines set by any such intermediary and each Clearing System for the submission and withdrawal of Tender Instructions will be earlier than the relevant deadlines set out above and in the Tender Offer Memorandum.
