Meyer Burger Investor Presentation

• Meyer Burger leads solar technology development Meyer Burger's ring-fenced approach of process, production equipment and product development within the captive business model yields strategic advantage Phase I: Current technology generation is undergoing continuous improvements (increased efficiencies, patented "Smart Corner" (prevention of soiling/moss formation for sustained high yields), glass-glass, M10 upgrade, etc.) Phase II (see photo): Process development for patented, indium- and (planned soon) silver-free, ultra-low degradation and manufacturing-cost-reduced back-contacted heterojunction solar cells for planned SWCT® module efficiencies of >24% without showstoppers ready for M10 wafers completed, now industrialization for fast manufacturing implementation (expected 2025) has started Phase III: Perovskite tandem development with industrialization focus in the works with 29.6% cell efficiency achievement¹ 1) Meyer Burger | Perovskite technology's potential to boost Europe's solar energy supply (csem.ch) MEYER BURGER Meyer Burger Technology AG, Presentation for Investors, Analysts and Media, August 17, 2023 11 Photo: MB Tile prototype with HJT-IBC solar cells
