ASX flags mining disclosure and ‘ramping’ in new supervision report

• ASX has released its first Listed Entity Supervision Report 2026, outlining new priority areas for how it oversees listed companies.
• The exchange says it will focus on potential ‘ramping’ behaviour through the announcements platform and on disclosures from mining companies.
• The goal, according to ASX, is to make supervision more proactive and risk‑based, and give issuers clearer guidance on its expectations.

ASX (ASX:ASX) has published its inaugural Listed Entity Supervision Report 2026 and used it to signal a sharper focus on market integrity risks, including how companies use the announcements platform and how miners report their activities.

The exchange said it is shifting towards proactive, risk‑based supervision and wants to give listed entities more clarity on topics such as its approach to earnings surprises, investor presentations and other disclosures that can move share prices.

“ASX’s purpose is to power a stronger economic future by enabling a fair and dynamic marketplace for all,” said ASX Group Executive, ASX Supervision, Lucinda McCann, who added that engagement with companies will be risk‑based, visible and transparent so issuers know what ASX will focus on and how it will respond to concerns.

Over the next 12 months ASX Supervision plans to target repeated conduct intended to “ramp” a company’s share price through inappropriate use of the market announcements platform, scrutinise disclosures from mining companies, and review how newly admitted entities describe private credit investments and how key shareholder approval rules are applied.

ASX has also expanded its education program by reinstating regular briefing sessions and updates for company secretaries to improve understanding of listing rule issues and supervisory expectations; following the announcement the ASX (ASX:ASX) share price was unchanged at its last reported level.

The report brings together, for the first time in a single document, details of ASX Supervision’s work over the nine months to 30 March 2026, including more than 2,500 advices provided, over 300 waivers processed, more than 700 misconduct reports considered, over 2,000 matters investigated and 20 referrals made to ASIC.

ASX said Supervision, formerly known as ASX Compliance, monitors all issuers and participants for adherence to its Listing and Operating Rules and makes compliance and enforcement decisions independently from other parts of the business, with the new report intended to give the market a clearer view of how and where that oversight is being applied.
