Key Terms

Listing Rule 3.1, foreign private issuer, continuous disclosure, trading halt, +1 more

5 terms

Listing Rule 3.1 regulatory

"The Company confirms that it is in compliance with the Listing Rules and, in particular, Listing Rule 3.1."

foreign private issuer regulatory

"REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO RULE 13a-16 OR 15d-16"

A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.

continuous disclosure regulatory

"Guidance Note 8 Continuous Disclosure: Listing Rules 3.1 – 3.1B."

Continuous disclosure is the legal and market practice requiring companies to promptly share any important information that could affect their share price or investors’ decisions, such as major contracts, financial surprises, leadership changes, or safety issues. It matters because it keeps all investors working from the same facts — like a shop owner telling customers about a surprise sale or supply problem — so markets can price risk fairly and investors can make timely decisions.

trading halt regulatory

"you should discuss with us whether it is appropriate to request a trading halt in IMC’s securities under Listing Rule 17.1."

A trading halt is a temporary pause on buying and selling a particular stock imposed by an exchange or regulator, like pressing the pause button on a game so everyone can catch up. It is used to give the market time to absorb important new information or to prevent chaotic price swings, and matters to investors because it freezes the ability to trade, delays price discovery, and can change risk and strategy until normal trading resumes.

suspend trading regulatory

"ASX will likely suspend trading in IMC’s securities under Listing Rule 17.3.1."

Dear Ms Smejkalova

Immuron Limited (‘IMC’): Price Query

ASX refers to the following:

A. The change in the price of IMC’s securities from a low of $0.032 at close of trade yesterday 27/05/2026 to a high of $0.044 today at the time of writing.

B. The significant increase in the volume of IMC’s securities traded today.

Request for information

In light of this, ASX asks IMC to respond separately to each of the following questions and requests for information:

1. Is IMC aware of any information concerning it that has not been announced to the market which, if known by some in the market, could explain the recent trading in its securities?

If the answer to question 1 is “yes”.

(a) Is IMC relying on Listing Rule 3.1A not to announce that information under Listing Rule 3.1? Please note that the recent trading in IMC’s securities would suggest to ASX that such information may have ceased to be confidential and therefore IMC may no longer be able to rely on Listing Rule 3.1A. Accordingly, if the answer to this question is “yes”, you need to contact us immediately to discuss the situation.

(b) Can an announcement be made immediately? Please note, if the answer to this question is “no”, you need to contact us immediately to discuss requesting a trading halt (see below).

(c) If an announcement cannot be made immediately, why not and when is it expected that an announcement will be made?

2. If the answer to question 1 is “no”, is there any other explanation that IMC may have for the recent trading in its securities?

3. Please confirm that IMC is complying with the Listing Rules and, in particular, Listing Rule 3.1.

4. Please confirm that IMC’s responses to the questions above have been authorised and approved under its published continuous disclosure policy or otherwise by its board or an officer of IMC with delegated authority from the board to respond to ASX on disclosure matters.
