4. Explanation of results

The reported loss after tax of the current financial year of $5,253,209 (2024: $6,936,957) is after fully expensing the company’s research and development expenditure of $3,597,296 incurred during the year (2024: $5,375,461). Of which, $146,252 (2024: $2,599,458) was funded by the R&D grant from Medical Technology Enterprise Consortium (MTEC).

The revenue from contracts with customers for the year was $7,287,002, which is an increase of 48.6% from the prior financial year (2024: $4,902,865), primarily due to the sales increase in the Australian and North American markets for Travelan®. We anticipate that revenues from sales of our Travelan® product will continue to increase in the future.

As at 30 June 2025, the company’s cash position was $2,830,526 (30 June 2024: $11,657,315). The company had trade and other receivables of $1,888,370 (30 June 2024: $1,387,573). This receivables amount includes future receivables from the Australian Government under the R&D Tax Incentive program. The company had other current assets of $3,486,744 (30 June 2024: $96,841). This other current assets amount includes a 90-day fixed term deposit of $3,036,278 (30 June 2024: Nil), which matured on 27 July 2025.

(i) Fair value of R&D tax incentive

The Group’s research and development (R&D) activities are eligible under an Australian government tax incentive for eligible expenditure. Management has assessed these activities and expenditure to determine which are likely to be eligible under the incentive scheme. Amounts are recognised when it has been established that the conditions of the tax incentive have been met and that the expected amount can be reliably measured. For the year ended 30 June 2025, the Group has included an item in other income of $1,073,355 (2024: $764,981).

Classification as trade receivables

Trade receivables are amounts due from customers for goods sold or services performed in the ordinary course of business. They are generally due for settlement within 30 days and therefore are all classified as current. Trade receivables are recognised initially at the amount of consideration that is unconditional unless they contain significant financing components, when they are recognised at fair value. The Group holds the trade receivables with the objective to collect the contractual cash flows and therefore measures them subsequently at amortised cost using the effective interest method.

Notes to the consolidated financial statements

3. Trade and other receivables (continued)

Accrued receivables

These amounts primarily comprise receivables from the Australian Taxation Office in relation to the R&D tax incentive.

Fair value of trade and other receivables

Due to the short-term nature of the current receivables, their carrying amount is considered to be the same as their fair value.

The Group entered into a 90-day fixed term deposit, which matured on 27 July 2025. Term deposits are presented as Other Current Assets as they are not considered highly liquid instruments readily convertible to cash and cash equivalents.

7. Share-based payments

Performance rights

Performance rights which can be settled in shares, were granted to key management personnel and employees during the year. The expense for the year ended 30 June 2025 was $239,488. The performance rights are based on non-market weighted key performance indicators (KPIs) and have been expensed over the service period, based on the probability the KPIs being achieved. The performance rights are expected to vest between one and five years.

Options

Options were approved at the Annual General Meeting, held on 18 November 2024 for Prof. Ravi Savarirayan and Mr. Daniel Pollock of 1,000,000 each. The option exercise price is $0.145 and they have an expiry date of 20 August 2028. The expense for the year was $34,952.

Options were granted to Dr. Jeanette Joughin on 19 June 2024 but were subject to shareholder approval obtained on 18 November 2024. The expense of $20,632 recorded in the year includes an adjustment for the revised estimate of fair value on the grant date of 18 November 2024.

Fair value is determined using the Black-Scholes option pricing model that takes into account the exercise price, term of the award, security price at grant date, expected volatility, expected dividend yield and the risk-free interest rate.

The model inputs for the options granted during the year:

Grant date	Expiry date	Exercise price ($A)		No. of options		Share price at grant date		Expected volatility			Dividend yield			Risk-free interest rate			Fair value at grant date per option
18-NOV-24	20-AUG-28	$	0.145		2,000,000	$	0.079		74.51	%		0.00	%		4.15	%	$	0.033
18-NOV-24	19-JUN-28	$	0.130		1,000,000	$	0.079		75.72	%		0.00	%		4.15	%	$	0.035

8. Events after the reporting period

At The Market Capital Raising

In July 2025, Immuron Limited (ASX: IMC), raised gross proceeds of USD$1,822,322 (AUD$2,809,177) through an At The Market Facility comprising 34,260,960 shares at an average issue price of of USD$0.053 (AUD$0.082) per share.

No other matter or circumstance has arisen since 30 June 2025 that has significantly affected, or may significantly affect the Group’s operations, the results of those operations, or the Group’s state of affairs in future financial years.
