ASX Limited

The Business

ASX sits at the centre of Australia's capital markets: it lists companies, clears and settles every trade, and runs the derivatives market that banks and super funds use to hedge interest rate risk. Roughly a third of revenue comes from trading and clearing activity that rises and falls with market volatility. Another quarter comes from data services, which grow steadily with the size of the market itself. This mix of activity-based and subscription-based revenue is unique among ASX-listed financials: no bank or insurer has this combination of monopoly licence and fee-based, capital-light economics.

Recent Performance

FY26 revenue grew 13.3%, but that came off elevated interest rate volatility that pushed futures volumes and clearing activity to record levels, a cyclical tailwind rather than a repeatable growth rate. EBITDA margins held at 61.0%, down from 72% four years ago as ASIC-mandated technology and compliance spending has permanently raised the cost base. The stock has re-rated alongside the broader market's appetite for defensive, monopoly-style earnings, pushing it to the upper end of its historical valuation range.

Outlook

FY27 is set up as a trough year: guided cost growth well ahead of expected revenue growth, as rate volatility normalises and pushes the EBITDA margin down from current levels. Margin recovery is expected to follow through FY28-30 as one-off transformation costs roll off, though the recovery is likely to land well short of the prior peak margin. Revenue growth should resume at a more moderate pace annually post-FY27, supported by superannuation and ETF growth rather than rate volatility.

Key Risks

Rate volatility normalisation is the nearest-term risk: a reversal in the current cycle could meaningfully reduce futures volumes and the trading revenue that has been running at cyclical highs. Margin compression is the structural risk: ASIC-mandated cost growth has already cut EBITDA margins by more than 1,000 basis points since FY22 and shows no clear sign of reversing, meaning the cost base embedded in the business today may be permanent rather than transitory. A third, lower-probability but high-impact risk is regulatory scope expansion: extending cost-based pricing rules from clearing and settlement into data services, currently the highest-margin part of the business, would strip value from the one segment generating genuine structural growth.

What to Watch

• Feb 2027 H1 FY27 results — the thesis-defining event, revealing whether the margin trough bottoms out at a level consistent with a durable recovery path.
• Sep 2026 New CEO Attia commences — sets strategic direction after three CEO changes in three years.
• FY28 Cost stabilisation test — whether expense growth decelerates as guided will determine if the margin recovery thesis holds.

Company Description

ASX operates four main businesses. Markets, covering cash equities trading and derivatives, contributes around a third of revenue and is the most volatile line, rising and falling with rate uncertainty and trading volumes. Securities and Payments, which includes clearing and settlement of every trade on the exchange, is the largest single segment and structurally tied to market activity levels. Technology and Data, roughly a quarter of revenue, sells market data subscriptions and grows with the size of the market rather than its volatility. Listings, the smallest segment, earns annual fees indexed to company market capitalisation.

Where the Growth Is

Technology and Data, currently 24% of revenue, is the structural growth engine. Australia's superannuation system is expected to grow from $4.4 trillion to $12 trillion over the next two decades, and ETF funds under management are growing at 33% per annum. Both trends mechanically increase demand for ASX's data, listing and settlement services regardless of rate cycles. This is the basis for a sustainable mid-single-digit revenue growth assumption once the FY27 cyclical normalisation passes.

Competitive Position

ASX's advantage is regulatory, not competitive: it holds the sole licence for exchange, clearing, settlement and derivatives trading in Australia, with market share of 82-100% across these functions. No rival has successfully challenged this position, and the barriers, licensing requirements, network effects across 2,042 listed entities, and the sheer cost of replicating settlement infrastructure, mean no credible threat exists over the next decade. The trajectory is stable rather than improving: the moat is durable but not widening, and the regulator that grants the monopoly also caps some of its pricing power through cost-based pricing rules on clearing and settlement.

Management & Capital Discipline

Management has maintained a disciplined 75-85% payout ratio with minimal M&A, and FY26 financial delivery came in ahead of internal budget. But three CEOs in three years and the CHESS settlement system project failure, which triggered a regulatory inquiry and ongoing compliance costs, represent a genuine execution failure that undermines confidence in strategic delivery. Capital returns are further constrained through FY27 by a $150m regulatory capital shortfall that must be closed before payout ratios can rise toward the top of the range.

Financial Position

ASX carries minimal debt relative to earnings and holds an investment-grade credit rating, reflecting the predictability of monopoly cash flows. The balance sheet can absorb a severe earnings downturn without financial stress, since fixed costs are covered many times over by recurring data and listing fee income even in a low-volatility trading environment. This financial strength is a genuine positive, and it forms part of the case for the business, though it does not by itself resolve the question of what to pay for the shares today.
