Rua Bioscience announces opening of Rights Offer
Rua Bioscience Limited (“Rua”) is pleased to announce the opening of its 1 for 3 pro rata
renounceable rights offer (“
Rights Offer”) to raise up to approximately NZ$2.8 million (if fully
subscribed). The Rights Offer was announced on 22 September 2026 and will primarily fund the
inventory and working capital needed to meet growing customer demand, in particular under
Rua’s largest export agreement to date in the United Kingdom.
Under the Rights Offer, eligible shareholders with a registered address in New Zealand or
Australia may apply for 1 new share for every 3 existing shares held at 5.00pm (NZDT) on the
record date of 29 September 2026, at an issue price of NZ$0.025 per new share. The issue price
represents a 32% discount to the 20-day volume weighted average price of Rua shares traded
on the NZX Main Board up to 17 September 2026. Up to approximately 113.1 million new shares
will be issued under the Rights Offer (33% of existing shares on issue).
The Rights Offer is renounceable. Rights are quoted on the NZX Main Board, with rights trading
having commenced on 28 September 2026 and closing on 9 October 2026. Eligible
shareholders who choose not to take up their entitlements may sell some or all of their rights
on the NZX Main Board, subject to sufficient demand for the rights. Eligible shareholders who
take up their rights in full may also apply for any number of additional new shares at the same
issue price under the Oversubscription Facility. Any shortfall shares may also be made
available to new investors.
New shares issued under the Rights Offer will rank equally in all respects with Rua’s existing
ordinary shares.
Full details regarding the Rights Offer are set out in the Offer Document and Investor
Presentation, which were released to the NZX on 22 September 2026. All eligible shareholders
are encouraged to read these documents in full, visit

Offer closes on Thursday, 15 October 2026.
