It has come to our attention that spam emails purportedly from our company president and fake job postings purportedly offering employment opportunities at Daiichi Sankyo and asking the recipient to reply with personal information, including bank details, have been circulating. Domain names have included addresses such as "@daiichi-pharma.com" and have been sent by persons called "Jeanne Regulaire" and "Jeanne Moreau." Daiichi Sankyo has no relationship with these maliciously intended spam emails and fake job postings.

Please immediately delete any such spam emails you receive, and please do not respond to any job postings purportedly from Daiichi Sankyo which ask for personal information.

Please contact us via the "Inquiry Form" below regarding suspicious emails or job postings.
