ORANO // Annual Activity Report 2024

Orano - Annual Activity Report 2024 44 2 SITUATION AND ACTIVITIES OF THE COMPANY AND ITS SUBSIDIARIES DURING THE PAST FINANCIAL YEAR The group’s businesses Orano’s other activities include the other cross-business functions, as well as Nuclear Medicine. Nuclear Medicine Orano’s Nuclear Medicine business is mainly carried out by Orano Med, its medical subsidiary. Orano Med has developed a unique process to extract and produce lead-212 (212Pb), which is a particularly rare alpha-emitting radioactive isotope, at a very high degree of purity. Orano Med is developing promising treatments that combine lead-212 with various biological molecules that target cancer cells. This innovative approach is called targeted alpha-therapy. It can recognize and destroy cancer cells selectively, limiting the impact on surrounding healthy cells. Orano Med’s ambition is to develop effective and targeted anticancer therapies in two strategic areas: ● developing innovative treatments using Orano Med’s lead-212 through scientific partnerships or 100% Orano Med projects; and ● building the production plants to produce high-purity lead-212 and thus meet the needs of current clinical development and future marketing of drugs.
