5 November 2026 Contact sets initial Interest Rate for green Capital Bonds Contact Energy Limited (Contact) has set the initial Interest Rate for its issue of $350 million unsecured, subordinated, redeemable, cumulative, interest-bearing green capital bonds (Capital Bonds) at 5.80% per annum. This is the Minimum Initial Interest Rate. The initial Interest Rate will apply until the First Reset Date (19 May 2032). The Interest Rate will be reset on the First Reset Date and every 5 years after that, 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. The Capital Bonds are expected to be issued on 19 November 2026 and quoted on the NZX Debt Market on 20 November 2026 under ticker code CEN100. As a result of the successful bookbuild process, Contact will redeem its existing 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. Contact will issue a formal notice of redemption to all holders of the CEN060 Bonds today.
