Australia's ASX Sees Higher FY27 Expenses on Tech, Compliance Spending

Shares in ASX Limited (ASX: ASX) fell sharply on Tuesday, May 26, 2026, after Australia's main stock exchange operator raised its FY27 expense growth guidance to between 18% and 21% — its highest projected cost increase in years — driven by an accelerating technology modernisation program, expanded compliance spending under its "Accelerate Program," and rising capital expenditure. The announcement, made at ASX's June 2026 Investor Forum, sent shares toward their worst single-session decline since April.

The Numbers: FY27 Expense Guidance in Full

ASX issued FY27 total expenses growth guidance of between 18% and 21%. Operating expense growth, excluding depreciation and amortisation, is guided to between 13% and 16% compared to FY26 total expenses. Additionally, ASX increased its FY27 capital expenditure guidance from the previous range of $160–$180 million to $180–$200 million, and also flagged FY28 capex of $170–$190 million, while leaving FY26 capex guidance unchanged.

ASX also agreed to sell its 49% interest in property settlement provider Simpli to its joint venture partner ATI Group for a nominal amount, incurring an after-tax loss of around $12 million — which will be recognised as a significant item in FY26. The Simpli divestiture reflects a strategic decision to sharpen ASX's focus on its core exchange and clearing infrastructure, rather than adjacent property settlement services.

What's Driving the Cost Surge

ASX attributed the expense growth to three primary drivers: its technology modernisation program, its expanded 'Accelerate Program' implemented as part of its response to the ASIC inquiry, and investments to support future growth initiatives. The Accelerate Program — ASX's multi-year strategic overhaul launched in the wake of a damaging regulatory inquiry into its failed CHESS replacement project — has consistently been the single largest driver of cost escalation at the exchange operator since its launch.

The technology modernisation agenda spans a wide range of infrastructure upgrades including trading platform resilience, clearing and settlement system replacement, software licence renewals, and cybersecurity enhancements. In parallel, the compliance dimension of the Accelerate Program requires ASX to implement all recommendations stemming from the ASIC inquiry — a process that involves significant legal, operational, and technology expenditure.

Context: A Multi-Year Cost Escalation Story

Tuesday's guidance is the latest in a pattern of progressively higher cost forecasts that have weighed on ASX's share price for several years. Earlier guidance had flagged total expense growth of 8–11% for FY26, with operating expense growth of 4–7%, driven by technology costs from software licence charges, costs associated with delivery of the Accelerate Program, and legal expenses. The jump to 18–21% for FY27 total expense growth represents a dramatic acceleration — and will test investor patience given ASX's premium listed valuation.

Over the medium term, ASX is targeting an expansion of its EBITDA margin and an underlying return on equity in the range between 13% and 14.5%. The company intends to lower capital expenditure after FY27 as major infrastructure upgrades near completion. ASX aims to start reducing capex from FY28 as major upgrades reach completion. That trajectory — peak spending in FY27, then a gradual easing — is the key message management is trying to deliver to investors, even as near-term cost pressure dominates the headlines.

What CEO Helen Lofthouse Said

ASX Managing Director and CEO Helen Lofthouse acknowledged both progress and remaining challenges: "It's pleasing to be at the stage in our strategy where we can show steady progress of key deliverables. This is particularly the case for our technology modernisation program in the way we've been engaging with our customers and stakeholders. We still have a way to go, and there are areas such as operational risk and business continuity where we are working to make further improvements."

Lofthouse's framing — progress on technology delivery, ongoing work on operational risk — reflects the tightrope ASX management must walk between demonstrating strategic momentum and managing investor frustration over persistently rising costs. The ASIC inquiry's shadow continues to loom large over the organisation's governance and reputation.

What Investors Need to Watch

For investors, the key questions are whether ASX can deliver on its FY28 capex reduction promise, whether the Accelerate Program's compliance expenditure has a defined endpoint, and whether revenue growth — supported by higher trading volumes and new product initiatives — can offset the near-term margin pressure from surging expenses.

With ASX shares falling sharply on the FY27 guidance, the market's verdict is clear: the cost story is not yet over, and the promise of post-FY27 margin expansion will need to be backed by tangible evidence of spending discipline before investor confidence is fully restored.
