ASX Limited

The Business

ASX is the sole operator of Australia's equity exchange, futures market, central clearing counterparty (which guarantees trades between buyers and sellers) and securities settlement system. Every listed equity trade, every interest rate futures contract, every share transfer in Australia flows through ASX infrastructure. Revenue splits roughly into four segments: Markets (trading and clearing, 32% of FY25 revenue), Technology & Data (market data feeds and connectivity, 25%), Settlement & Post-Trade (settlement and registry services, 25%) and Listings (annual fees from 2,200+ listed entities, 19%). The integrated vertical model means ASX earns multiple fees from a single transaction as it moves from execution through to settlement.

Recent Performance

FY25 revenue grew 7.0% to $1,107m off a base that itself grew 4.3%, driven by elevated derivatives volumes as the RBA held rates at their highest level in over a decade. EBITDA margins held at 62.8%. The first half of FY26 accelerated further, with revenue up 11.2% to $603m as futures volumes hit records and cash market values surged 23%. Margins compressed to 61.4% as ASIC inquiry costs ($17.3m in the half) and the Accelerate governance programme absorbed the revenue uplift.

Outlook

We forecast revenue of $1,210m in FY26 before growth decelerates sharply to 0.7% in FY27 as trading volumes normalise from cyclical peaks. The RBA is at its 100th percentile policy rate, and when that cycle resolves, futures and cash market revenues compress simultaneously. Structural growth resumes at 4-5% from FY28 as Australia's superannuation system ($4.1 trillion today, projected to reach $11 trillion) expands the underlying pool of assets requiring exchange, clearing and settlement services. EBITDA margins trough near 59.7% in FY27 before recovering to 60-61%, permanently below the 62.8% FY25 level due to structural compliance costs.

Key Risks

Cyclical volume reversion is the most probable near-term risk. Futures and cash market revenues could fall simultaneously as the RBA cycle resolves, compressing ASX's two largest segments (57% of revenue combined). ASIC cost escalation, where expense guidance was already revised upward twice in a single quarter, could compress margins further below our terminal assumption. The pending Federal Court ruling on ASX's batch settlement incident carries additional downside through penalties and increased regulatory scrutiny.

What to Watch

The thesis-defining event is the FY26 full-year result in August 2026, which will reveal whether second-half expense growth confirms or contradicts the structural cost thesis.

• June 2026 ASIC Federal Court ruling — penalty quantum will set the tone for ongoing regulatory costs and could trigger further compliance investment.
• H2 CY2026 New CEO appointment — the most important personnel decision in a decade. The market's assessment of the appointee's credibility will influence the multiple investors are willing to pay for ASX's uncertain cost trajectory.

Latest Developments

CHESS Release 1, the replacement for ASX's ageing settlement system, was delivered in April 2026 after years of delays and a failed blockchain-based predecessor. The CEO departed during the ASIC transformation period, leaving a vacancy at the top during the company's most significant governance overhaul in decades. Cboe Australia has received its exchange licence, creating the first competitive threat to ASX's listings monopoly.

Company Description

ASX Limited operates Australia's financial market infrastructure across four divisions. Markets ($349m, 32% of FY25 revenue) earns fees from trading and clearing equities, derivatives and futures. Technology & Data ($276m, 25%) sells market data feeds, trading connectivity and technical services to financial institutions. Settlement & Post-Trade ($274m, 25%) processes the legal transfer of securities ownership and provides registry services. Listings ($208m, 19%) charges annual and initial fees to the 2,200+ entities listed on the exchange. The company also earns approximately $87m in net interest income on $12 billion of participant collateral held in its clearing house, a function of its role as central counterparty guaranteeing the settlement of every trade.

Where the Growth Is

Technology & Data is the structural growth engine. At $276m in FY25, it grew 8.2% off a base that itself grew 6.5%, making it the most consistent segment. Data feeds carry switching costs because financial institutions build trading systems around ASX's proprietary formats. We forecast this segment reaching $338m by FY28, contributing $60-80m of incremental revenue. As Australia's superannuation pool scales from $4.1 trillion toward $11 trillion, institutional demand for market data, connectivity and analytics expands structurally regardless of trading volumes.

Competitive Position

ASX holds exclusive Australian market licences to operate the exchange, central counterparty and settlement depository. These licences are granted under the Corporations Act. Replicating them would require legislative change, making the barrier to entry functionally absolute for clearing and settlement, which together account for 57% of revenue. The integrated vertical structure (listing through to settlement) means ASX earns multiple fees per transaction, a model competitors cannot replicate without matching all four functions. Cboe Australia's exchange licence creates the first real threat, but only to listings (19% of revenue). Even a 20% erosion of listings revenue over a decade costs just $4m per year. The clearing monopoly is untouched, because every trade, regardless of which exchange it executes on, must clear and settle through ASX infrastructure. This advantage will persist for at least a decade absent regulatory intervention that currently shows no signs of materialising.

Management & Capital Discipline

Capital allocation has been competent if unspectacular. ASX pays out 75-85% of earnings as fully-franked dividends, with the payout temporarily reduced to 75% to fund a $150m net tangible asset capital build required by regulators. Capex peaked at $176-180m annually for the CHESS replacement programme, well above the $50-60m maintenance level. The original CHESS replacement, an ambitious blockchain-based system, was abandoned after years of delays and a $250m write-off, representing the most significant capital allocation failure in the company's history. The Chair's public admission of a "defensive and insular" organisational culture is rare executive candour, but it also undermines management's own guidance for medium-term margin expansion. Expense guidance revised upward twice in a single quarter, from 8-11% to 13-15%, suggests management itself is still discovering the full scope of ASIC-required investment.

Financial Position

ASX's balance sheet is fortress-grade. The company holds an AA- credit rating from S&P, carries $275m of gross debt (a single floating-rate note maturing February 2027) against $1.45 billion in cash and investments. After setting aside $1.15 billion of regulatory capital required for clearing operations, excess cash sits at approximately $260m. Net debt is effectively zero. Free cash flow conversion runs near 100% of reported earnings. Revenue would need to decline more than 50% before the company faced any financial stress, a scenario with no historical precedent and no plausible mechanism given the monopoly structure.
