Contact lodges product disclosure statement Capital Bond

22 October 2026 Contact lodges product disclosure statement for green Capital Bond offer Contact Energy Limited (Contact) has today lodged a product disclosure statement (PDS) for an offer of up to $225 million (with the ability to accept oversubscriptions at Contact’s discretion) of unsecured, subordinated, redeemable, cumulative, interest-bearing, green capital bonds (Capital Bonds) to New Zealand retail and institutional investors (Offer). The proceeds of the Offer will be used by Contact for the financing and refinancing of renewable generation and other eligible green assets in accordance with the terms of Contact’s Sustainable Finance Framework. If the bookbuild for the Offer is successful, Contact intends to exercise its right to redeem its $225 million green capital bonds quoted on the NZX Debt Market under the ticker code CEN060 (CEN060 Bonds) on 19 November 2026, being the first reset date for the CEN060 Bonds. Each CEN060 Bond would be redeemed at its principal amount of $1.00, together with any accrued but unpaid interest. Trading in all CEN060 Bonds is expected to be suspended from market close on 5 November 2026. Contact expects to issue a formal notice of redemption to holders of the CEN060 Bonds on or about 5 November 2026. The Capital Bonds will have a term of 30.5 years. Contact may choose to repay some or all of the Capital Bonds early in certain circumstances, including on any Reset Date (5.5 years after the Issue Date and every 5 years after that). The Interest Rate will be fixed for an initial period of 5.5 years, after which it will be reset on each Reset Date, unless redeemed earlier by Contact. Contact may, in its absolute discretion, defer any payment of interest on the Capital Bonds for up to 5 years. If an interest payment is deferred, the deferred interest will itself accrue interest (compounding on each Interest Payment Date) at the prevailing Interest Rate on the Capital Bonds until the Interest Payment Date on which all Unpaid Interest is paid. Unpaid Interest is cumulative. The Capital Bonds have been assigned an issue credit rating of BB+ by S&P Global Ratings (S&P), which is two notches below S&P’s issuer credit rating for Contact reflecting their subordination and the potential for interest payments to be deferred. The Offer is expected to open on 2 November 2026, and the indicative Initial Margin range and the Minimum Initial Interest Rate will be announced on the same date. The Offer is expected to close on 5 November 2026, and the Initial Margin and the initial Interest Rate will be announced on the same date. The Capital Bonds are expected to be issued on 19 November 2026 and quoted on the NZX Debt Market on 20 November 2026. Details of the Offer and the Capital Bonds are contained in the PDS, which is attached and available on the Disclose register at www.disclose-register.companiesoffice.govt.nz (offer number OFR15288) and at www.contact.co.nz/capitalbondoffer, or by contacting a Joint Lead Manager or your usual financial adviser, and must be obtained by investors before they decide to acquire any Capital Bonds. There is no public pool for the Offer, with all the Capital Bonds being reserved for clients of the Joint Lead Managers, institutional investors and other primary market participants invited to participate in the bookbuild. Investors can register their interest in the proposed Offer by contacting one of the Joint Lead Managers or their usual financial adviser. This Offer is being made in accordance with the Financial Markets Conduct Act 2013. The investor presentation and indicative terms sheet for the Capital Bonds are also attached. Contact also advises that it has amended its Master Trust Deed dated 21 August 2015 (as restated and/or amended from time to time) to provide that notices or other communications to holders of a listed series will be deemed to be given to those holders on the date that Contact publishes such notice or communication via the NZX market announcement platform.
