It then expects further capex of $170 million to $190 million in FY 2028.
Commonwealth Bank of Australia (ASX: CBA)

However, it is worth noting that all of the big four banks are trading lower today. It is possible that some large investors are rotating funds out of the banks and into other areas of the market.
Endeavour Group Ltd (ASX: EDV)
The Endeavour share price is down 4% to $2.95. This follows the release of the drinks giant's strategy update this morning. Although the Dan Murphy's and BWS owner has a bold new strategy in place, which includes cost savings of $300 million, it has announced a reduction in its dividend payout ratio to conserve cash.
Tuas Ltd (ASX: TUA)
The Tuas share price is down a further 2% to $2.12. This Singapore-based telco's shares have been under significant pressure since it terminated its proposed acquisition of M1 Limited.

It said: "Simba continues to co-operate with the investigation being undertaken by the Infocomm Media Development Authority into potential breaches of the Telecommunications Act and the conditions of Simba's Facilities-Based Operator Licence. Tuas will keep shareholders updated in relation to that investigation."
