Funding update: Seeking to monetise royalty-bearing ABZENA Inside products

Cambridge, UK, 14 June 2018 - Abzena plc (AIM: ABZA, 'Abzena' or the 'Company', and together with its subsidiaries, the 'Group'), a life sciences group providing services and technologies enabling the development and manufacture of biopharmaceutical products, provides an update on its fundraising activities.

At the time of the recent full-year results announcement on 4 June 2018, the Board noted that additional working capital will be required within the next twelve months to support the Group.

Abzena has recently been in market sounding discussions with institutional investors regarding a potential equity fundraising. In consultation with the Company's major shareholders, the Board has decided to prioritise the potential partial monetisation of its interests in certain ABZENA Inside products.

The Group has entered into a non-binding heads of terms agreement with an unconnected third party under which it would sell an interest in its entitlements to future royalties which may arise from certain ABZENA Inside products. The parties have now entered into a limited period of exclusivity for completion of due diligence and negotiation of definitive agreements. While there can be no assurance that the transaction will be completed, the Board believes that, if completed, the funds received will be sufficient for the Group's short term working capital needs.

The Board will continue to explore near-term funding options available to the Group including, but not limited to, equity and/or debt financing in order to satisfy the Group's ongoing working capital requirements.

The Company will provide further updates on this matter in due course.

This announcement is released by Abzena plc and contains inside information for the purposes of Article 7 of the Market Abuse Regulation (EU) 596/2014 ("MAR"), encompassing information relating to the Group's fundraising activities, and is disclosed in accordance with the Company's obligations under Article 17 of MAR.

For the purposes of MAR and Article 2 of Commission Implementing Regulation (EU) 2016/1055, this announcement is being made on behalf of the Company by John Burt, Chief Executive Officer.
