ASX Ltd shares fell sharply after the Australian Securities Exchange warned that fiscal 2026 costs will rise far more than previously expected, overshadowing a modest increase in first-half profit. The exchange operator now forecasts total expenses to climb between 20% and 23% this financial year, up from earlier guidance of 14% to 19%, as it absorbs mounting costs linked to system outages, regulatory scrutiny, and an ongoing ASIC investigation.
The update triggered a sell-off, with ASX shares dropping as much as 2.6% to A$53.92, extending the prior session’s 6.2% decline. The stock underperformed the broader benchmark index, which gained 0.5%, reflecting investor concerns over rising operational risk and governance challenges.
For the six months ended December 31, ASX reported underlying net profit after tax of A$263.6 million, up from A$253.7 million a year earlier. Stronger trading volumes supported earnings growth, but escalating expenses weighed heavily on overall performance. Total costs surged 20% to A$264.3 million, driven by regulatory probe expenses, business transformation initiatives, ageing technology infrastructure, and intangible asset write-offs.
Leadership uncertainty has added to pressure on the exchange, with CEO Helen Lofthouse planning her departure. The transition comes as ASX faces intensified regulatory attention following a CHESS batch settlement failure in late 2024. The company has since released an incident review and pledged a A$1 million credit disbursement to affected settlement participants through fee rebates.
Further operational setbacks, including an August 2025 name mix-up and a December outage on its announcements platform, have drawn additional scrutiny. Meanwhile, the Australian Securities and Investments Commission is conducting a sweeping review of ASX’s governance and operational risk management framework, with a final report expected by March 31, 2026. ASIC inquiry costs are projected to reach the top end of the A$25 million to A$35 million range.
Despite cost pressures, ASX declared a fully franked interim dividend of 101.8 Australian cents per share, down 8.5% year-on-year, reflecting a 75% payout ratio at the lower end of its revised guidance.
