Further Result of Fundraising

Further to its announcement on 3 May 2024, Ondine Biomedical Inc. (AIM: OBI), is pleased to announce that, due to increased demand from existing and new investors, it has increased the amount raised in its Placing, to a revised total of approximately £3.24 million (C$5.57 million). The amount raised via the Subscription is unchanged.

As a result, the total raised in its Placing and Subscription (the "Fundraising") is now approximately £3.54 million (C$6.07 million), at the Issue Price of 7 pence per New Common Share.

Further details on the Fundraising are included in the Company's announcement of 8.00 a.m. on 3 May 2024.

The total gross proceeds of the Fundraising are approximately £3.54 million (C$6.07 million) and the estimated net proceeds are expected to be approximately £3.37 million (C$5.70 million).

The Placing has conditionally raised aggregate gross proceeds of approximately £3.24 million (C$5.57 million) pursuant to the placing of 46,349,297 Placing Shares with new and existing investors. As previously announced, the Subscription has raised gross proceeds of approximately £0.29 million (C$0.50 million) pursuant to subscriptions received for 4,182,673 Subscription Shares.

The 50,531,970 New Common Shares in aggregate to be issued pursuant to the Fundraising represent approximately 22.3 per cent. of the existing issued share capital of the Company, or approximately 18.2 per cent. of the share capital of the Company as enlarged by the Fundraising.

All shares issued pursuant to the Fundraising will be issued non pre-emptively under the Company's existing authorities, and are expected to be admitted to trading on AIM on or around 9 May 2024.

Due to the increase in the placing quantum, the Company will now be issuing 25,265,978 Warrants in conjunction with the Fundraising, on the basis of one Warrant for every two Placing Share(s) or Subscription Share(s) purchased. Each Warrant can be exercised over one Common Share within nine months of Admission, at an exercise price of 15 pence.

Orana Corporate LLP ("Orana") acted as Joint Broker to the Placing and Singer Capital Markets Securities Limited ("SCM") acted as Bookrunner for the Placing. The Placing was conducted following a market sounding by way of an accelerated book build process.

Admission, Settlement and Dealings

Admission of the Placing Shares and Subscription Shares will take place on or around 8.00 a.m. on 9 May 2024 and dealings on AIM in the Placing Shares and the Subscription Shares will commence at the same time. Admission is conditional upon, among other things, the Placing Agreement becoming unconditional and not being terminated, and the Subscription being carried out within the Company's existing statutory authority to issue shares on a non pre-emptive basis.

The Placing Shares and Subscription Shares when issued, will be fully paid and will rank pari passu in all respects with the existing Common Shares, including the right to receive all dividends and other distributions declared, made or paid after the date of issue.

Total Voting Rights

Following admission of the Placing Shares and Subscription Shares, the Company's issued and fully paid share capital will consist of 277,285,759 Common Shares, each carrying one voting right per Common Share. The Company does not hold any Common Shares in treasury. Therefore, from Admission, the total number of Common Shares and voting rights in the Company will be 277,285,759.

This figure may be used from the date of Admission until further notice by existing shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

UK Product Governance Requirements

Solely for the purposes of the product governance requirements contained within chapter 3 of the FCA Handbook Product Intervention and Product Governance Sourcebook (the "UK Product Governance Requirements") and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the UK Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in chapter 3 of the FCA Handbook Conduct of Business Sourcebook ("COBS"); and (ii) eligible for distribution through all permitted distribution channels (the "UK Target Market Assessment"). Notwithstanding the UK Target Market Assessment, distributors should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in Placing Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The UK Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Placing. Furthermore, it is noted that, notwithstanding the UK Target Market Assessment, the Bookrunner will only procure investors who meet the criteria of professional clients and eligible counterparties.

For the avoidance of doubt, the UK Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of chapters 9A or 10A respectively of the COBS; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to Placing Shares. Each distributor is responsible for undertaking its own target market assessment in respect of the shares and determining appropriate distribution channels.

Solely for the purposes of Article 9(8) of Commission Delegated Directive 2017/593 (the "Delegated Directive") regarding the responsibilities of Manufacturers under the Product Governance requirements contained within: (a) Directive 2014/65/EU on markets in financial instruments, as amended ("MiFID II"); (b) Articles 9 and 10 of the Delegated Directive; and (c) local implementing measures (the "MiFID II Product Governance Requirements"), and disclaiming all and any liability, whether arising in tort, contract or otherwise which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Placing Shares have been subject to a product approval process, which has determined that the Placing Shares are (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the "Target Market Assessment"). Notwithstanding the Target Market Assessment, Distributors (as defined within the MiFID II Product Governance Requirements) should note that: the price of the Placing Shares may decline and investors could lose all or part of their investment; the Placing Shares offer no guaranteed income and no capital protection; and an investment in Placing Shares is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the proposed Placing. Furthermore, it is noted that, notwithstanding the Target Market Assessment, the Bookrunner will only procure investors who meet the criteria of professional clients and eligible counterparties. For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability of appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Placing Shares.
