Solar Foods' collaboration with Fermenta is a step towards strengthening Solein's brand recognition and establishing a market in the United States. While we believe this is a step in the right direction on Solein's path to commercialization, we do not expect the collaboration to have a significant direct impact on Solar Foods' figures due to the small size of the partner.

Promoting commercialization through expected measures

Solar foods announced on Wednesday that US start-up Fermenta will introduce Solein®-powered protein bars. A limited amount of products sold under the Gutsy brand will be available to consumers in the first quarter of 2026. This will be one of the first consumer products in the US to feature Solein. This will give Solein the visibility it needs in the main market area for the product.

The announcement aligns with our expectations as Solar Foods has previously stated its intention to focus on the Health & Performance category in its commercialization efforts in the US market. We believe Solar Foods can leverage start-ups like Fermenta to generate consumer interest and visibility in various product categories. Partnering with an agile start-up company also enables rapid market entry and feedback collection.

Valuable visibility for future negotiations

Although we estimate that the volume and direct financial impact of the product batch launched by Fermenta will be negligible for Solar Foods, the collaboration will generate valuable visibility in the company's most important market area. This visibility and new product launches will increase Solein's recognition and credibility among consumers and potential larger food industry partners alike. The positive reception of the protein bars could prove Solein's suitability for this category, supporting future negotiation of agreements involving significantly higher volumes.

The foundation of Solar Foods' investment case remains the successful financing and commercialization of the industrial-scale Factory 02. However, smaller collaborations like this one are necessary milestones on the road to larger volumes because they verify the existence of market demand and reduce the risk associated with investing in Factory 02. While the news is positive and supports the company's investment story, we estimate that its direct financial impact will be limited.
