Paris, France, and Manchester, UK - 18 March 2025 - Novacyt S.A. (EURONEXT GROWTH: ALNOV; AIM: NCYT), an international molecular diagnostics company with a broad portfolio of integrated technologies and services, provides an update further to the Health and Safety Executive ("HSE") Prosecution announcement made on 21 January 2025 (RNS: 1680U).

Lab21 Healthcare Ltd ("Lab 21"), a non-trading subsidiary of Novacyt, has pleaded guilty at Exeter Magistrates Court today to health and safety charges relating to the historical operation of its site in Axminster, Devon between 28 June 2018 and 5 April 2019.
