Agreement Extended with Bonals Technologies

Itaconix plc (AIM: ITX) (OTCQB: ITXXF), a leading innovator in high-performance plant-based specialty polymers used in everyday consumer products, such as homecare detergents, announces an extension of its collaboration with Bonals Technologies ("Bonals") through to December 2028 under the Company's SPARX Formulated Solutions business. The program seeks to speed the introduction of safer, better performing, cost effective, and more sustainable unit dose detergent tablets in the United States and Canada.

As announced in November 2024, Itaconix and Bonals signed an agreement to collaborate on developing new generations of detergents that leverage the synergistic benefits of Itaconix formulations produced on Bonals tableting equipment. In 2025 the two companies worked together to install a pilot-scale tablet press in Itaconix's North American Innovation Center to develop its patented 8-gram plastic-free dish detergent tablet.

This collaboration resulted in Itaconix introducing a new dish detergent tablet at the American Cleaning Institute's Innovation Showcase in February 2026 which is generating high levels of interest from purpose-driven brands in North America. The new tablet is available on the Company's deeperclean.com ecommerce site, and was also featured in a recent Chemical and Engineering News article on the new potential and growth in solid unit-dose detergents.

As demand for the Company's Performance Ingredient grows to existing North American contract tablet makers, the extended collaboration will assist Itaconix in progressing efforts with contract manufacturers to install high-speed Bonals tablet presses that produce more compact and faster dissolving tablets based on the synergy between their compression cycle and Itaconix detergent polymers. The Company plans to use its pilot-scale press to gain commercial traction and build volumes for its proprietary tablet with a select number of brands.

Olivier Desmarescaux, CEO of Bonals Technologies, commented:

"We are excited about the innovative detergent tablets that Itaconix has developed on our tableting press. I believe our collaboration with Itaconix is keeping us at the forefront of introducing high-performing, plastic-free tablets in North America that are both competitively priced and better for the environment. We expect continued success working together on new opportunities in North America."

John R. Shaw, CEO of Itaconix, commented:

"Our work with Bonals and purpose-driven brands in our North American Innovation Center is demonstrating the sizable opportunity for us to replicate our success of European tablets in North America. We are particularly excited about the positive response to our patented 8-gram plastic-free dish detergent tablet produced on a Bonals tablet press. The extension of our collaboration with Bonals offers us further opportunities for leading a new generation of solid unit-dose detergents."
