Simply Wall St · 2d ago

What Westpac’s Q3 2026 earnings tell you

Westpac Banking (ASX:WBC) has drawn fresh attention after its Q3 2026 update, which showed net profit excluding notable items of A$1.8b, slightly lower than a year earlier, while net operating income held at A$5.7b.

The bank followed the earnings call with a detailed Q3 2026 Investor Discussion Pack and its June 2026 Pillar 3 regulatory report. Together, these disclosures outline capital, funding and risk metrics that many investors watch closely when assessing a large Australian bank.

Westpac Banking’s latest Q3 update and regulatory disclosures have arrived after a softer patch for the stock, with the share price down 8.1% over the year to date. However, the 1 year total shareholder return of 7.2% and the very large 3 year total shareholder return of close to 9x suggest long term holders have still seen strong compounding, even as shorter term momentum has faded in recent weeks.
