NAB’s profit stable as business banking strength, offset by rising bad debts, tech costs

National Australia Bank said a year of business lending strength was offset by rising technology and bad debt costs as it posted an adjusted net profit up 1 per cent to $6.76 billion for the 12 months ending September 30, 2025.

Its statutory net profit slipped 0.2 per cent to $7.09 billion just shy of analysts’ expectations, as operating expenses rose 4.6 per cent to $9.85 billion over the financial year.

“We are making good progress on our key priorities of growing business banking, driving deposit growth and strengthening home lending,” said chief executive Andrew Irvine.

“We also need to grow revenues faster than costs, and what we delivered in the back half of the year shows revenue growing 4.3 per cent, and those are the types of numbers we need to show next year and consistently to improve operating leverage for our shareholders.”

Dividends flat, bad debts higher

The country’s largest business lender will pay a final dividend of 85 cents per share for the six months ending September 30 to take full-year dividends to $1.70 per share, flat on the prior financial year. Earnings per share climbed 1.1 per cent to $2.32 on revenue up 1.2 per cent to $20.8 billion.

Bad debts booked in financial year 2025 rose to $833 million, versus $728 million in the prior financial year. Mr Irvine said the bad debt growth over the second half of the financial year should slow going forward.

“We were clear at the beginning of the year we expected the peak in asset quality delinquencies to be in the back half of the year and that’s what materialised. As far as I’m concerned, things are playing out as we would’ve expected,” he said.

Total profits in its core business and private banking segment climbed 1.6 per cent to $3.33 billion.

Over the second half of its financial year, total business lender balances grew by 5.8 per cent, a result the bank said was its strongest growth in more than three years.

Mr Irvine added that he’s seeing signs the Australian economy has improved over the six months to September 30, although rising energy costs are hurting households and businesses.

Tech, AI investments

The bank reported more than 15,000 of its staff now use artificial intelligence to save time on routine tasks, with 4,500 tech staff using generative AI tools for software development.

Mr Irvine added that the bank is also focused on developing AI agents to provide value to customers, although pushed back on the idea it could use the technology to help price interest rates and other terms on business or home loans.

“In terms of credit risk, we’ve always had models that drive automated decision making and we’ll continue to leverage those, but I think we’ll go a little bit slowly on leveraging AI to make credit decisions,” Mr Irvine said. “I want to make sure there are not unintended consequences with that for our customers.”

Shares opened up 0.8 per cent to $44.89 and have added 13.4 per cent over the past 12 months. The bank’s dividend yield sits at 3.8 per cent before any additional tax benefits from franking credits. Return on equity dropped 0.2 per cent to 11.4 per cent, versus 11.6 per cent in the financial year 2024.
