Confirming the Relevance of AFYREN’s Business Model and Advancing the Industrial Production Ramp-up

• AFYREN, a committed player in climate change mitigation and adaptation for the chemical sector, continues its growth:

  • The milestone of 1,000 tonnes of bio-based acids produced since the start of the ramp-up has been exceeded1, including 200 tonnes produced following the July restart

  • The demonstrated production capacity2 was pushed to 30% on multiple occasions and reached 40% over a 48-hour period following the June 2026 works, to be confirmed over long production periods

  • The plant's production process and water recycling system have demonstrated resilience during heatwaves and water stress

• AFYREN targets a further doubling of AFYREN NEOXY revenue in H2 2026 compared to H1 2026

CLERMONT-FERRAND, France & LYON, France, August 27, 2026--Regulatory News:

AFYREN, a greentech company offering manufacturers biobased, low-carbon ingredients through a unique fermentation technology based on a circular model, provides an update on the operational performance of its AFYREN NEOXY plant and shares its outlook for the second half of 2026.

Following the resumption of operations in July 20263, production quickly exceeded 200 tonnes of acids, as well as a significant volume of associated fertilizers. The works carried out in June 2026 contributed to increasing demonstrated production capacity (actual production volume over a given period as a percentage of the plant's nominal capacity). This indicator was pushed to 30% on multiple occasions, peaking at 40%4 over a 48-hour period. The challenge now is to sustain these levels over long production periods through improvements in industrial control and enhanced reliability to increase the plant's overall efficiency rates.

Despite actual performance remaining below team expectations as of today in August 2026, with corrective actions already being rolled out, the AFYREN NEOXY plant crossed the symbolic threshold of 1,000 tonnes of acids produced since the start of the ramp-up phase in June 2025, thereby validating its transition to commercial industrial scale.

Laurent POU, AFYREN's COO, commented: "The June shutdown marked a critical milestone in overcoming our main technical bottlenecks. Our ambition is now to embed these performance levels into our daily operations, by accumulating production hours and driving continuous process improvement."

These milestones are being achieved during a period marked by several large-scale heatwaves, which are affecting many players across the traditional chemicals industry and the broader industry sector. In this context, AFYREN benefits from a model that addresses both transition challenges—with a highly decarbonized approach compared to the petrochemical industry—and adaptation challenges. Its prudent use of water resources, supported by a production water recycling system, is a good example of this: It enables AFYREN to continue operations even when other industrial players are forced to declare force majeure5.
