BSF Enterprise PLC:

A Historic Milestone in Luxury and Biotechnology -

World's First T-Rex Leather™ handbag to be auctioned

BSF Enterprise PLC ("BSF" or the "Company"), a global pioneer in lab-grown tissues and sustainable biotechnology, is pleased to announce a landmark event in the evolution of luxury materials. Its subsidiary, Lab-Grown Leather Limited, has officially appointed the prestigious Paris-based auction house Giquello SAS to facilitate the sale of the world's first-ever product crafted from T-Rex Leather™. Engineered using reconstructed dinosaur collagen and brought to life without harming a single animal, T-Rex Leather™ made its first public debut on 2 April, where the one-of-a-kind, Enfin Leve designed handbag was unveiled at the Art Zoo in Amsterdam.

A Preeminent Stage for a Masterpiece

The auction will be a centerpiece of Giquello's renowned Tentation°4 sale, scheduled for 11 June 2026 at the historic Drouot headquarter in Paris. Giquello SAS was specifically selected for its unrivaled expertise in natural history and high-value curiosity sales, providing the perfect bridge between prehistoric legacy and futuristic innovation.

VML Paris, a key partner in the creation of T-Rex Leather™ and a driver of its initial media success, will lead the promotion of the auction, ensuring this historic milestone resonates with audiences worldwide.

BSF views this auction as a transformative opportunity to showcase the Company's innovation to the global market:

● Global Prestige: Hosting the event at Drouot, Paris-the epicenter of the French art market-elevates T-Rex Leather™ to the status of a masterpiece, engaging an elite international network of collectors and connoisseurs.

● Market Disruption: This milestone validates the commercial viability of the proprietary ATEP™ platform, demonstrating that cultivated leather can compete at the highest echelons of the luxury industry.

● Brand Amplification: Collaborating with VML Paris ensures a sophisticated campaign, positioning the brand prominently before luxury, technology, and design audiences worldwide.

CEO Perspective: Defining the Future of Luxury

Dr. Che Connon, CEO of BSF, stated:

"The auction of the world's first T-Rex Leather™ product in Paris is a watershed moment for our Company and our shareholders.

With the strategic support of VML Paris, we are not just selling a product; we are introducing a new asset class to the luxury market. This represents the pinnacle of what our biotechnology can achieve, merging the majesty of natural history with the ethics of tomorrow. This is an exciting moment for T-Rex Leather™ and for the wider potential of cultivated materials in luxury, fashion and design."
