Capital raise – Pro-rata renounceable Rights Offer

Rua is today announcing an offer to existing shareholders an opportunity to participate in our renoucenable rights issue of 1 New Shares for every 3 Existing Shares to raise up to $2million (“ Rights Offer ”).

The Rights Offer, if fully subscribed, along with proceeds of the expected Gisborne property sale, is expected to fund the business to a self-sustaining position.

This comes at a pivotal stage in the company’s evolution, with Rua now generating meaningful revenue across three markets — Germany, Australia, and New Zealand. FY25 revenue of $1.9 million represents strong growth from $322,000 in FY24. With the growth trajectory now well established, the Board and management expect revenue to exceed $3 million by the end of FY26.

Rua intends to use the cash raised through the Rights Offer to fund working capital and marketing activities to support our growth opportunities. This includes new products in our key international markets of Germany, Australia, UK and Czechia.

The Rights Offer, if fully subscribed, along with proceeds of the expected Gisborne property sale, is expected to fund the business to a self-sustaining position.

The issue price under the Rights Offer is $0.025 per share, representing a 35% discount to the 5-day volume weighted average price of Rua shares up to 31 October 2025. Rua notes that this price reflects that the Rights Offer is being offered to existing eligible shareholders resident in New Zealand or Australia and differs to the potential issue of new shares authorised by shareholders at the recent annual shareholders’ meeting at an issue price of $0.03 per share via a potential placement to new investors.

Eligible shareholders who take up their rights in full may also apply for any number of additional shares at the same issue price under the Oversubscription Facility.

The key dates for the Rights Offer are as follows:
