Elenia Verkko Oyj announces Tender Offer for its €500,000,000 0.375 per cent. Secured Bonds due 6 February 2027

29 September 2025 Elenia Verkko Oyj (the "Offeror") announces today its invitation to holders of the outstanding €500,000,000 0.375 per cent. Bonds due 6 February 2027 (ISIN: XS2113885011) (the "Bonds"), issued by the Offeror, to tender their Bonds for purchase by the Offeror for cash subject to satisfaction (or waiver) of the New Financing Condition (as defined below) and the other conditions described in the Tender Offer Memorandum (as defined below) (such invitation, the "Offer").  The Offer is being made on the terms and subject to the conditions contained in the tender offer memorandum dated 29 September 2025 (the "Tender Offer Memorandum") prepared by the Offeror and is subject to the offer and distribution restrictions set out below and as more fully described in the Tender Offer Memorandum.

Copies of the Tender Offer Memorandum are (subject to the offer and distribution restrictions) available from the Tender Agent as set out below. Capitalised terms used in this announcement but not defined have the meanings given to them in the Tender Offer Memorandum.

Summary of the Offer

A summary of certain of the terms of the Offer appear below:

Rationale for the Offer

The Offer is being made as part of the Offeror's proactive balance sheet management strategy in optimising its debt maturity profile. Furthermore, the transaction provides liquidity or reinvestment optionality to those Bondholders whose Bonds are accepted in the Offer. It is intended that any Bonds purchased by the Offeror pursuant to the Offer will be cancelled and not subsequently reissued or resold.

Purchase Price and Accrued Interest

The Offeror will, on the Settlement Date, pay for Bonds validly tendered and accepted by it for purchase pursuant to the Offer, a cash purchase price (expressed as a percentage, the "Purchase Price") to be determined at or around 11.00 a.m. (London time) on 8 October 2025 (the "Pricing Time") (subject to the right of the Offeror to amend such time and date in its sole discretion and without prior notice to Bondholders) in the manner described in the Tender Offer Memorandum by reference to the "Purchase Yield", which shall equal the sum of (i) the Purchase Spread specified in the table on page 1; and (ii) the Interpolated Mid-Swap Rate (as defined in the Tender Offer Memorandum).

The Purchase Price will be determined in accordance with market convention and expressed as a percentage of the nominal amount of 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 the Maturity Date 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 on the Bonds up to and including the Maturity Date, discounted to the Settlement Date at a discount rate equal to the Purchase Yield, minus (b) any Accrued Interest for the Bonds.

The Offeror will also pay accrued and unpaid interest in respect of Bonds validly tendered and accepted for purchase pursuant to the Offer, from (and including) the immediately preceding interest payment date for such Bonds to (but excluding) the Settlement Date, calculated in accordance with the terms and conditions of the Bonds.

Final Acceptance Amount and Scaling

The Offeror proposes that (subject to satisfaction or waiver of the New Financing Condition) the aggregate nominal amount of Bonds (if any) which it will accept for purchase pursuant to the Offer will be an amount of up to €250,000,000 (the "Maximum Acceptance Amount"), although the Offeror reserves the right, in its sole and absolute discretion, to accept significantly more or significantly less than (or none of) the Maximum Acceptance Amount for purchase pursuant to the Offer (the final nominal amount accepted for purchase pursuant to the Offer being the Final Acceptance Amount).

If the Offeror decides to accept for purchase any Bonds validly tendered pursuant to the Offer and the aggregate nominal amount of Bonds validly tendered pursuant to the Offer is greater than the Final Acceptance Amount, the Offeror intends to accept such validly tendered Bonds for purchase (subject to satisfaction or waiver of the New Financing Condition on or prior to the Settlement Date) on a pro rata basis such that the aggregate nominal amount of Bonds accepted by the Offeror for purchase pursuant to the Offer is no greater than the Final Acceptance Amount.

New Financing Condition

The Offeror announced on 29 September 2025 its intention to issue a new series of euro-denominated fixed rate bonds (the New Bonds) pursuant to its €3,000,000,000 multicurrency bond programme (the "Programme").  Whether the Offeror will accept for purchase Bonds validly tendered in the Offer is subject (unless such condition is waived by the Offeror in its sole and absolute discretion), without limitation, to the successful completion (in the sole determination of the Offeror) of the issue of the New Bonds (the "New Financing Condition").

Even if the New Financing Condition is satisfied (or waived), the Offeror is not under any obligation to accept for purchase any Bonds validly tendered pursuant to the Offer.  The acceptance for purchase by the Offeror of Bonds validly tendered pursuant to the Offer is at the sole and absolute discretion of the Offeror and tenders may be rejected by the Offeror for any reason.

Any investment decision to purchase any New Bonds should be made solely on the basis of the information contained in (i) the Base Prospectus dated 23 September 2025 (the "Base Prospectus") prepared in connection with the Programme; and (ii) the final terms relating to, and to be prepared in connection with, the New Bonds, and no reliance is to be placed on any representations other than those contained in the Base Prospectus..

The New Bonds are not being, and will not be, offered or sold in the United States. Nothing in this announcement constitutes an offer to sell or the solicitation of an offer to buy the New Bonds in the United States or any other jurisdiction. Securities may not be offered, sold or delivered in the United States absent registration under, or an exemption from the registration requirements of, the United States Securities Act of 1933, as amended (the "Securities Act"). The New Bonds have not been, and will not be, registered under the Securities Act or the securities laws of any state or other jurisdiction of the United States, and may not be offered, sold or delivered, directly or indirectly, within the United States or to, or for the account or benefit of, U.S. persons (as defined in Regulation S of the Securities Act).

MiFID II product governance - The target market for the New Bonds for the purposes of Directive 2014/65/EU (as amended, "MiFID II") is eligible counterparties and professional clients only (all distribution channels), each as defined in MiFID II, and all channels for distribution of the New Bonds to eligible counterparties and professional clients are appropriate.

The New Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA"). For these purposes, a "retail investor" means a person who is one (or more) of: (i) a retail client as defined in point (11) of MiFID II; (ii) a customer within the meaning of Directive (EU) 2016/97, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129. Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the New Bonds or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the New Bonds or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

The New Bonds are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes, a "retail investor" means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law of the United Kingdom by virtue of the EUWA; or (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000, as amended (the "FSMA") and any rules or regulations made under the FSMA to implement Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of UK MiFIR; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law of the United Kingdom by virtue of the EUWA (the "UK PRIIPs Regulation") for offering or selling the New Bonds or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the New Bonds or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

No action has been or will be taken in any jurisdiction in relation to the New Bonds to permit a public offering of securities.

Allocation of the New Bonds

The Offeror will, in connection with the allocation of the proposed issue of New Bonds by or on behalf of the Offeror, consider among other factors whether or not the relevant Bondholder seeking an allocation of the New Bonds has validly tendered, or indicated a firm intention to the Offeror or the Dealer Managers to tender, their Bonds pursuant to the Offer, and, if so, the aggregate nominal amount of the Bonds validly tendered or intended to be tendered by such Bondholder (subject to such Bondholder making a separate application for the subscription of the New Bonds to the joint lead managers of the issue of the New Bonds). When considering allocation of the New Bonds, the Offeror may give preference to those Bondholders who, prior to such allocation, have validly tendered or indicated their firm intention to the Offeror or to the Dealer Managers to tender their Bonds pursuant to the Offer and subscribe for New Bonds. Any such preference in the allocation of the New Bonds will be applicable up to the aggregate nominal amount of Bonds tendered or firmly indicated to be tendered by such Bondholder pursuant to the Offer. However, the Offeror is not obliged to allocate the New Bonds to a Bondholder who has validly tendered or indicated a firm intention to tender its Bonds for purchase pursuant to the Offer. Any allocation of the New Bonds, while being considered by the Offeror as set out above, will be made in accordance with customary new issue allocation processes and procedures and, if New Bonds are allocated, the nominal amount thereof may be less or more than the nominal amount of Bonds tendered by such Bondholder and accepted by the Offeror pursuant to the Offer. In the event that a Bondholder validly tenders Bonds for purchase pursuant to the Offer, such Bonds will remain subject to such tender and the conditions of the Offer as set out in the Tender Offer Memorandum irrespective of whether that Bondholder receives all, part or none of any allocation of New Bonds for which it has applied.

A Bondholder wishing for its Tender Instruction or its intention to tender Bonds to be taken into account in the allocation process for the New Bonds should contact the Dealer Managers in accordance with the standard new issue procedure of such Dealer Manager, or by contacting the Dealer Managers using the contact details set out below. The pricing of the New Bonds is expected to take place prior to the Expiration Deadline and, as such, Bondholders are advised to contact the Dealer Managers as soon as possible, and prior to the allocation of the New Bonds, in order for this to be taken into account as part of the New Bonds allocation process.

Tender Instructions

In order to participate in, and be eligible to receive the Purchase Consideration and the 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 7 October 2025 (the "Expiration Deadline").  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 Bonds of no less than €100,000, being the minimum denomination of the Bonds, and may be submitted in integral multiples of €1,000 thereafter.

The times and dates below are indicative only. Accordingly, the actual timetable may differ from the timetable below.

The above times and dates are subject to the right of the Offeror to extend, re-open, amend, and/or terminate the Offer (subject to applicable law and as provided in the Tender Offer Memorandum).

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. The deadlines set by any such intermediary and each Clearing System for the submission of Tender Instructions will be earlier than the relevant deadlines set out above and in the Tender Offer Memorandum.
