- ASX Ltd ended Thursday at A$50.81, down 2.29%, while the S&P/ASX 200 lost 0.62%.
- Draft rules would cap share-funded acquisitions by S&P/ASX 300 companies at 25% of existing capital without a shareholder vote.
- A separate CHESS settlement includes an A$20.5 million penalty and A$3 million of legal costs, subject to court approval.
ASX Ltd shares head into Friday trade after closing A$1.19 lower on Thursday. The stock ranged from A$50.73 to A$52.61, with 1.38 million shares changing hands, above its recent daily average.
The timing is awkward. ASX operates listings, trading, clearing and settlement, leaving investors to judge both its regulation of listed companies and its ability to deliver core market infrastructure after years of technology strain.
Under the draft rules, S&P/ASX 300 bidders could issue no more than 25% of their existing capital to fund a public takeover or merger without investor approval, down from 100%. Dilution means that issuing new shares reduces existing investors’ percentage ownership. Airlie Funds Management’s Matt Williams said, “We support the changes,” while Allan Gray chief investment officer Simon Mawhinney argued that smaller-company shareholders should also receive protection.

ASX received 45 responses from asset managers, industry groups, banks, lawyers and listed companies. It is seeking further submissions by July 29 on the takeover rules and proposed voting requirements for voluntary delistings and changes in listing status.
Thursday’s decline did not erase the stock’s recent recovery: ASX remained 4.1% above its June 11 close. The longer view is weaker, with the shares down 27.6% in the financial year to date—a sign that relief rallies have yet to remove the broader execution discount.
CHESS, the platform that records shareholdings and settles equity trades, remains central to that discount. The revised system’s first release went live in April, while full completion is projected for 2029. Kai Chen, a director at MPC Markets, said, “The fine closes a legal chapter,” but warned that reputational and structural questions remained. Reuters
The larger earnings concern is spending. ASX forecast fiscal 2027 expense growth of as much as 21% and capital expenditure of A$180 million to A$200 million, prompting a 13.2% share-price fall on May 26. Generate KiwiSaver investment specialist Greg Smith said investors were focused on whether management could execute “without more delays, outages or cost blowouts.” Reuters
But the M&A proposal can still change, and companies outside the ASX 300 remain excluded. For ASX shareholders, another technology delay or market outage would deepen the downside; clean CHESS delivery and closure of the court case could begin to narrow the risk attached to the stock. Previous disruptions have already drawn regulatory scrutiny.
Friday’s trading is therefore less a verdict on one consultation paper than a test of whether investors believe ASX’s governance reset can survive its delivery deadlines. A stronger rulebook helps. Reliability and cost control will decide more.
