As announced to the ASX earlier today, the Federal Court of Australia has made orders that CSS convene and hold a meeting of Clean Seas Shareholders to consider and vote on the proposed acquisition of CSS by Yumbah Aquaculture Ltd (“Yumbah”) by way of scheme of arrangement (“Scheme”) (“Scheme Meeting”) and approving the distribution to Clean Seas Shareholders of an explanatory statement in connection with the Scheme (“Scheme Booklet”).

Clean Seas confirms that the Scheme Booklet has today been registered with the Australian Securities and Investments Commission (“ASIC”). A copy of the Scheme Booklet, including the Independent Expert’s Report and the Notice of the Scheme Meeting, is attached to this announcement.

The Scheme Booklet will be sent to Clean Seas Shareholders as follows:

• Shareholders who have elected to receive electronic communications from Clean Seas will be sent an email containing instructions on how to view or download a copy of the Scheme Booklet, as well as instructions on how to lodge their Proxy Form;

• Shareholders who have elected to receive hard copies of communications from Clean Seas will receive a hard copy of the Scheme Booklet by post and a personalised Proxy Form; and

Unless otherwise indicated, capitalised terms used in this announcement have the meaning given to them in the Scheme Booklet dated on 13 May 2025, a copy of which is attached to this announcement.

Scheme Consideration

If the Scheme is approved and implemented, Clean Seas Shareholders will receive:

(a) the Default Cash Consideration - cash of $0.14 per ordinary share in the capital of Clean Seas (“Clean Seas Share”); or

(b) at the election of eligible1 Clean Seas Shareholders, an unlisted scrip alternative of one (1) newly issued ordinary share in the capital of Yumbah (“New Yumbah Share”) for every 3.1428 Clean Sea Shares (“Yumbah Scrip Alternative”).

If a valid Election is not made by a Clean Seas Shareholder or no Election is made by a Clean Seas Shareholder, then that Clean Seas Shareholder will receive the Default Cash Consideration for each Scheme Share that they hold.

If a Clean Seas Shareholder is an Ineligible Shareholder, they will not be entitled to receive New Yumbah Shares. Ineligible Shareholders will instead receive only the Default Cash Consideration for their Scheme Shares.

1 Clean Seas Shareholders from jurisdictions outside of Australia, New Zealand, Norway, Liechtenstein, Switzerland, and the United Kingdon, and Clean Seas Shareholders who hold less than the minimum parcel of 3,570 Clean Seas Shares, will be ineligible from making an Election to receive the Yumbah Scrip Alternative.

Independent Expert’s Report

The Scheme Booklet includes an Independent Expert’s Report from BDO Corporate Finance Ltd (“BDO”), which concludes that, based on the Default Cash Consideration, the Scheme is in the best interests of Clean Seas Shareholders, in the absence of a Superior Proposal. The Independent Expert only considered the Default Cash Consideration to assess the fairness of the Scheme with this being the default consideration under the Scheme. Neither the Independent Board Committee nor the Independent Expert have undertaken an evaluation of or make any recommendation to Clean Seas Shareholders in relation to the Yumbah Scrip Alternative. The Independent Expert’s conclusion should be read in context with the full Independent Expert’s Report and the Scheme Booklet.

The Independent Board Committee Recommends Voting in FAVOUR of the Scheme

The Clean Seas Independent Board Committee (“IBC”) unanimously recommends that, based on the Default Cash Consideration, Clean Seas Shareholders vote in favour of the Scheme in the absence of a Superior Proposal and subject to the Independent Expert continuing to conclude that the Scheme is in the best interests of Clean Seas Shareholders. Subject to the same qualifications, each member of the IBC intends to vote all Clean Seas Shares held or controlled by them in favour of the Scheme. The IBC makes no recommendation to Clean Seas Shareholders in relation to the Yumbah Scrip Alternative due to the highly speculative nature of the New Yumbah Shares and the fact that deciding whether the New Yumbah Shares are appropriate for an individual Clean Seas Shareholder will depend on the characteristics and risk profile of that particular shareholder.

Scheme Meeting

The Scheme Meeting will be held in person at 11:00am (Adelaide time) on Monday 23 June 2025 at Grant Thornton, Level 3, 170 Frome Street, Adelaide SA 5000.

Clean Seas Shareholders registered on the Clean Seas Share Register at 7:00pm (Adelaide Time) on 20 June 2025 will be entitled to vote on the Scheme.

All Clean Seas Shareholders are encouraged to vote by attending the Scheme Meeting or alternatively by completing the Proxy Form accompanying the Scheme Booklet.

Clean Seas Shareholders are encouraged to read the Scheme Booklet carefully and in full before deciding whether to vote in favour of the Scheme.
