ASX Announcement

23 June 2026

**Unmarketable Parcel Facility Update**

Immuron Limited (ASX: IMC; NASDAQ: IMRN) (**Immuron** or **Company**) refers to its announcement dated 13 April 2026 and is pleased to announce that it has completed its small holding share sale facility (**Facility**).

The Company offered the Facility for shareholders with less than a marketable parcel based on its share price and share register as at close of trade on 8 April 2026 (**Record Date**). Under Australian Securities Exchange (**ASX**) Listing Rules, a marketable parcel of shares is a parcel of ordinary shares (**Shares**) of not less than $500, based on the closing price of the Shares on the ASX.

Under the terms of the Facility, shareholders who held 18,518 or less Shares in an individual holding at the Record Date were eligible to participate (**Eligible Shareholder**). Eligible Shareholders had until 5.00pm (Sydney time) on 1 June 2026 to opt out of the Facility or increase their individual shareholding to a marketable parcel (**Closing Date**). Eligible Shareholders that did not exercise either of these options by the Closing Date have had their Shares acquired (**Participating Shareholders**).

As previously announced, the Company appointed Henslow to sell the Shares under the Facility either on the market or in any other manner they consider to be fair and reasonable. Henslow has advised the Company that the offer from the Company to buy-back the Shares (in accordance with section 257B of the *Corporations Act 2001* (Cth)) at the price of $0.032 per share, being the Volume Weighted Average Price calculated over the 5 trading days (15 June – 19 June) (**Sale Price**) is currently the best price reasonably obtainable for the Shares.

Accordingly, the Participating Shareholders will receive the Sale Price for each Share bought-back by the Company (**Buy-back**). No brokerage or any other costs were included in calculating this Sale Price, thereby allowing Participating Shareholders to sell their Shares without incurring any transactional costs.

Any tax consequences arising from the sale of the Shares will be the Participating Shareholders' responsibility. Tax may be payable on any gains made on the sale of the Shares. This will depend on individual personal taxation circumstances. Participating Shareholders should obtain independent tax advice from an appropriate tax adviser regarding any questions they have about their personal taxation circumstances.

![](ea029556901_ex99-1img3.jpg)

In total, 3,805,528 shares have been acquired and will be cancelled by the Company, which had an aggregate value of $121,777. The Company expects that following this completion of the Buy-back, it will reduce the administrative costs of managing small holdings.

As at the Closing Date, the outcome of the Buy-back on the Company's capital structure is as follows:

---

| | |
|:---|:---|
| Number of ordinary shares on issue before completion of the Buy-back | 326653609 |
| Number of shareholders before completion of the Buy-back | 2264 |
| Number of ordinary shares on issue after completion of the Buy-back | 322848081 |
| Number of shareholders after completion of the Buy-back | 1253 |

---

The Sale Price will be dispatched to Participating Shareholders in the coming days to the bank account registered with Boardroom Pty Limited (**Share Registry**). If Participating Shareholders bank account details are not up to date or not recorded, a cheque will be sent to the postal address as shown in the share register.

**This announcement has been authorised by the Board of Immuron.**

The platform can be used to block viruses or bacteria at mucosal surfaces such as the Gastrointestinal tract and neutralize the toxins they produce.
