Eurofins (Paris:ERF):

As communicated in an adhoc press release on Monday June 3^rd, during the weekend of 1^st/2^nd June, Eurofins Scientific (EUFI.PA) was affected by a ransomware attack which caused disruption to many of its IT systems in several countries. Eurofins IT staff and their internal and external IT security teams and experts took prompt actions to contain the incident, mitigate its impact including by taking many systems offline and have been working around the clock to return the IT operations to normal in the companies of the Group that have been affected. As Eurofins IT teams reacted promptly many of the Group’s companies were able to continue operating without impacting customers. Moreover, on Tuesday June 4^th we were able to resume full or partial operations for a number of impacted companies and have continued to do so every day since then. As a result, as of Monday June 17^th, the vast majority of affected laboratories’ operations had been restored. The production and reporting IT systems of essentially all those that remained became operational again during the past week. Restoration operations are continuing for some less important back office and software development systems as well as in a few companies (representing less than 2% of the Group’s revenues) some specific procedures required before restart of certain activities that are anticipated to be completed by end of next week.

Eurofins companies have alerted and are cooperating with law enforcement agencies and renowned IT forensics and security companies in the investigation of this matter. Forensics investigations are ongoing but we have identified the variant of the malware used and it is now being recognised and when detected neutralized by our IT security solutions as updated with the versions released on Sunday June 2^nd and thereafter. Additional security tools we are deploying since then as well as the world class cyber security experts who are supporting us are and will be providing additional protection and monitoring. We are continuing to work intensively with leading cybersecurity experts to further secure our current systems and infrastructure and to add enhanced security features and measures to protect our systems and data. The investigations conducted so far by our internal and external IT forensics experts have not found evidence of any unauthorised theft or transfer of confidential client data. The security of our client data and of all our IT systems is of the utmost importance to Eurofins. Eurofins companies remain committed to making significant investments in the continuous improvement of the security of their IT systems.
