ASX Limited (ASX: ASX) jumps 9% as A$536m profit meets FY27 cost surge

ASX Limited (ASX: ASX), the listed operator of Australia’s primary securities exchange and critical clearing, settlement, data and market infrastructure, has returned to retail-investor watchlists after its strongest one-day share-price gain in years. The shares closed at A$60.52 on August 13, up 9.03%, after ASX reported A$536.4 million of underlying net profit for fiscal 2026 and operating revenue of A$1.25 billion. The rally came even though statutory profit declined and management expects another substantial increase in technology and operating expenditure during fiscal 2027. The next phase of the investment case centres on whether stronger trading, clearing, listings and data revenue can continue outrunning a technology-modernisation bill that is still rising, with incoming chief executive Anthony Attia due to take charge on September 1.

Why did ASX Limited shares jump 9% after the FY26 results?

ASX Limited generated operating revenue of A$1.255 billion in the year ended June 30, 2026, an increase of 13.3% from A$1.107 billion a year earlier. Underlying net profit after tax increased 5.2% to A$536.4 million, while EBITDA rose 10% to A$765 million.

Those numbers show the benefits of an unusually active year for financial markets. Markets revenue increased 18.6% to A$414.1 million as futures and over-the-counter revenue rose 18.4% and cash-market trading revenue jumped 24.2%. Securities & Payments revenue increased even faster, rising 19.4% to A$327.7 million as higher transaction volumes supported clearing, settlement and Austraclear activity.

Technology & Data revenue rose 8% to A$297.6 million, while Listings revenue increased a more modest 3.5% to A$215.2 million. ASX recorded 100 new listings during FY26, up 45% from the previous year, and said new listings brought A$32.6 billion of quoted market capitalisation to the exchange.

The results therefore showed growth across all four operating divisions rather than dependence on one isolated revenue stream. Market volatility provided a particularly strong boost, but the recovery in listings and continuing demand for exchange data broadened the result.

The share-price reaction was substantial. ASX closed at A$60.52 compared with A$55.51 on August 12, a gain of A$5.01 or 9.03%. The shares had traded as high as A$62.90 during the session, briefly approaching their 52-week high.

Why did underlying profit rise while statutory profit fell?

The distinction between underlying and statutory earnings is particularly important in ASX Limited’s FY26 numbers.

Underlying net profit increased 5.2% to A$536.4 million, but statutory net profit declined 3.5% to A$484.9 million. The difference primarily reflects A$51.5 million of significant items recognised during the year.

ASX said those significant items included costs associated with settled Australian Securities and Investments Commission legal proceedings, payments connected with the CHESS Replacement Partnership Program and the loss on the sale of its interest in Sympli.

For investors assessing the recurring earnings power of the exchange, underlying profit provides a useful measure of operational performance. Statutory earnings remain important because the exceptional costs are real financial consequences, even when they are not expected to repeat at the same level each year.

The larger issue is that recurring expenditure is also rising rapidly. Total expenses increased 21.1% to A$557.4 million during FY26, substantially faster than the 13.3% increase in operating revenue. Depreciation and amortisation increased 40.1% to A$67.8 million as technology investments moved into operation.

That gap explains why a strong revenue year translated into only 5.2% underlying profit growth. ASX is generating more activity-related income, but a growing proportion of that improvement is being absorbed by the cost of rebuilding and modernising the exchange’s technology infrastructure.

Can revenue growth outrun another 18% to 21% rise in FY27 expenses?

This is arguably the most important numerical question for ASX shareholders after the results.

Management reaffirmed guidance for total FY27 expense growth of between 18% and 21%. Operating expenses excluding depreciation and amortisation are expected to increase between 13% and 16%, driven principally by technology modernisation, the Accelerate program and spending intended to support customer-led growth.

Applying the 18% to 21% range mechanically to FY26 total expenses of A$557.4 million implies FY27 expenses of approximately A$658 million to A$674 million.

That represents roughly A$100 million to A$117 million of additional annual expenditure.

For perspective, underlying net profit increased by only A$26.4 million during FY26. The expected incremental expense burden for FY27 is therefore roughly four times the amount by which underlying profit increased in the year just completed.

Another way to frame the hurdle is against revenue. Holding other variables constant, ASX would need roughly A$100 million to A$117 million of additional revenue simply to offset the guided increase in total expenses at the operating-profit level. That is equivalent to approximately 8% to 9% of FY26 operating revenue.

The calculation is deliberately simplified. Actual earnings will also be influenced by depreciation, interest income, tax, business mix and the timing of technology spending. It nevertheless shows why revenue growth remains so important even after an apparently strong FY26.

ASX produced 13.3% revenue growth last year, comfortably above that simplified 8% to 9% threshold. Repeating something close to that performance would make the higher expense base considerably easier to absorb. A normalisation in market volatility and trading activity could make the equation more difficult.

Has ASX made enough progress on CHESS and technology modernisation?

Technology execution sits at the centre of both the upside and risk cases.

ASX completed CHESS Release 1 during FY26, upgrading clearing services onto a newer technology platform. The company said the release also established cloud, data and integration capabilities intended to support future technology delivery.

ASX has also begun work to modernise its cash-market trading platform, ASX Trade, while the wider technology roadmap includes further development across market infrastructure.

These projects require significant capital. ASX expects FY27 capital expenditure of A$180 million to A$200 million, followed by another A$170 million to A$190 million in FY28. Management has said technology modernisation is the main driver of that spending.

The commercial logic is straightforward. ASX operates infrastructure on which Australia’s securities markets depend, so system capacity, resilience and reliability are fundamental to the value of the franchise.

The financial complication is equally clear. Technology modernisation increases expenses, depreciation and capital requirements before all of the economic benefits become visible. The Final Australian Securities and Investments Commission Inquiry Panel Report identified historical underinvestment compared with global peers, and ASX has committed to addressing that issue.

For shareholders, the most constructive outcome would therefore be fairly uneventful operational evidence: major technology milestones delivered on schedule, core systems remaining reliable during heavy market volumes and costs staying within the ranges management has already provided.

Repeated delays or additional spending beyond the existing roadmap would make the current earnings recovery less valuable because more revenue would be consumed by infrastructure investment.

Is ASX Limited expensive after the 9% share-price rally?

At A$60.52 per share and approximately 195.4 million shares outstanding, ASX Limited has an equity market capitalisation of about A$11.8 billion.

Dividing that market value by FY26 underlying net profit of A$536.4 million produces an underlying earnings multiple of approximately 22 times. That is not an especially low valuation for a company whose underlying profit grew 5.2%, although ASX’s infrastructure position, recurring data and listing revenues and high operating margins differentiate it from a conventional financial-services company.

The recent share-price move also changes the entry point significantly.

ASX closed at A$57.60 on August 7, meaning the stock is approximately 5.1% higher over the latest five completed trading sessions. Compared with A$54.57 on July 13, the shares have risen about 10.9% over one month.

The 52-week range is approximately A$44.30 to A$64.99. At A$60.52, ASX is only about 6.9% below the upper end of that range and roughly 36.6% above the low.

That positioning suggests the market has already restored a meaningful amount of confidence to the shares. Investors buying after the results are no longer assessing ASX near its May lows. They are assessing a company trading relatively close to its 12-month high while still facing another year of elevated expenditure.

Dividends remain part of the valuation argument. ASX declared a fully franked final dividend of A$1.047 per share, bringing the FY26 total to A$2.065. The full-year distribution was 7.5% lower than FY25 and represents a payout ratio of 75% of underlying net profit.

At the August 13 closing price, the FY26 distribution equates to a historical cash yield of approximately 3.4% before considering the value of franking credits. That is a backward-looking calculation rather than a forecast of the FY27 dividend.

What are the next milestones for ASX shareholders?

The first confirmed milestone is the arrival of Anthony Attia as managing director and chief executive officer on September 1. Attia joins from Euronext and brings extensive experience across exchanges, derivatives and post-trade infrastructure.

His immediate challenge will not be to invent a new investment thesis from scratch. ASX has already established the main priorities: technology modernisation, execution of the Accelerate program, improved resilience and the development of additional customer-driven products.

The second milestone is cost control. FY27 expense guidance of 18% to 21% leaves a relatively wide but clearly defined range against which investors can measure execution. Evidence that expenditure remains within guidance while revenue continues expanding would significantly improve earnings visibility.

Trading activity is another variable. FY26 benefited from exceptionally active and volatile markets, including ASX’s highest-ever month for futures trading volume and its second-largest equities trading day by number of executed trades. Those conditions cannot automatically be assumed to repeat.

Listings provide a potentially less volatile source of improvement. ASX said its new-listings pipeline is the strongest it has been in several years. Continued growth in IPOs, secondary raisings and dual listings could help broaden revenue growth if derivatives or cash-market activity normalises.

Finally, investors will need to monitor the technology roadmap itself. Delivery against the A$180 million to A$200 million FY27 capital-expenditure plan without major additional cost or schedule changes would provide practical evidence that ASX is moving from remediation toward a more predictable investment cycle.

ASX Limited stock key takeaways after the FY26 results

• ASX Limited shares closed 9.03% higher at A$60.52 on August 13 after the company reported stronger FY26 operating results.
• Operating revenue increased 13.3% to A$1.255 billion, while underlying net profit after tax rose 5.2% to A$536.4 million.
• Statutory net profit declined 3.5% to A$484.9 million after A$51.5 million of significant items.
• Total FY27 expenses are still expected to increase between 18% and 21%, implying approximately A$100 million to A$117 million of additional expenditure from the FY26 base.
• ASX expects FY27 capital expenditure of A$180 million to A$200 million as technology modernisation remains a major investment priority.
• At A$60.52, ASX carries a market value of about A$11.8 billion and trades at roughly 22 times FY26 underlying profit, with the shares less than 7% below their 52-week high.
• Incoming chief executive Anthony Attia starts on September 1, while cost control, technology delivery, listings activity and trading volumes provide the clearest measurable proof points for FY27.

What would strengthen or weaken the ASX Limited investment case from here?

ASX Limited enters FY27 with considerably better operating momentum than the headline statutory profit decline might suggest. Revenue grew across all four business units, underlying profit increased, CHESS Release 1 was delivered and activity across trading, clearing, settlement and listings was strong enough to produce double-digit group revenue growth.

What remains unresolved is whether that revenue momentum can persist while the cost base continues expanding rapidly. The simplified arithmetic shows the challenge clearly: another A$100 million to A$117 million of annual expenditure could require roughly 8% to 9% additional operating revenue merely to offset the incremental expense burden at the operating level.

The investment case would strengthen if ASX maintains high-single-digit or better revenue growth, keeps FY27 expenses within guidance, delivers its technology program without further material cost escalation and converts the stronger listings pipeline into additional fee income. A smooth leadership transition under Anthony Attia would add another layer of confidence.

The thesis would weaken if market activity normalises sharply while costs continue rising at the guided pace, or if major technology projects require additional spending without corresponding improvements in reliability and commercial capability.

The August 13 rally shows that investors are increasingly willing to look beyond ASX’s recent operational difficulties and focus on the earnings power of the underlying exchange franchise. At roughly 22 times underlying FY26 earnings and close to the 52-week high, however, the next stage requires more than a better narrative. ASX now needs to show that its growing revenue base can finance the technology rebuild without leaving profit growth permanently several steps behind.
