Infratil Limited (“Infratil") (NZX/ASX:IFT) has agreed to sell 53,531,358 ordinary shares in Contact Energy Limited (“Contact”) (NZX/ASX:CEN), comprising 5.0% of Contact’s issued share capital, via a fully underwritten block trade. The sale is at a price of NZ$9.25 per ordinary share, generating expected gross proceeds of approximately NZ$495.17 million, and is expected to complete on 25 May 2026.

Following the sale, Infratil’s shareholding in Contact will be approximately 9.08%. Infratil remains supportive of Contact and has committed to retaining its remaining shares through to, at least, Contact’s FY26 full year results announcement (expected on or around 18 August 2026), subject to customary exceptions.

Infratil CEO Jason Boyes said the transaction provides Infratil with additional flexibility to fund future growth opportunities.

“We received our initial stake in Contact as part of the sale of Manawa Energy in July 2025 and we remain confident in Contact and the sector’s outlook.

While we have no immediate funding requirements and our divestment programme is on track, we consider it prudent to reposition this capital now. This means we’re well prepared to support future growth opportunities across our portfolio,” he said.

Further details on the outlook for Infratil’s portfolio will be provided at its FY26 results announcement on Tuesday 26 May.
