Contact considers green Capital Bond offer

19 October 2026 Contact considers green Capital Bond offer Contact Energy Limited (Contact) is considering making 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). It is expected that full details of the Offer will be released later this week with the Offer expected to open during the week beginning 2 November 2026. The Capital Bonds are expected to be assigned a 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. If the Offer is made and the bookbuild is successful, Contact intends 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. It is expected that trading in all CEN060 Bonds will be suspended from market close on 5 November 2026. Contact will write to all holders of the CEN060 Bonds directly to notify them of the potential redemption and the trading suspension (a template letter is attached to this announcement). 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. Contact has appointed Forsyth Barr Capital Markets Limited as Arranger and Joint Lead Manager, and Bank of New Zealand and Craigs Investment Partners Limited as Joint Lead Managers in relation to the proposed Offer. Investors can register their interest in the proposed Offer by contacting one of the Joint Lead Managers or their usual financial adviser. Indications of interest will not constitute an obligation or commitment of any kind. No money is currently being sought and no Capital Bonds can be applied for or acquired until the Offer opens. If the proposed Offer is made, it will be made in accordance with the Financial Markets Conduct Act 2013. Application will be made to NZX for any Capital Bonds to be quoted on the NZX Debt Market on completion of the Offer.
