Pets First Group CSR Activity Report - February 2026

Pets First Holdings Co., Ltd. (Headquarters: Meguro-ku, Tokyo, CEO: Haruhiko Sakamoto) publishes the "Pets First CSR Activity Report" to communicate to a wider audience the CSR activities we conduct under the philosophy of "Pets always come first." In this report, as the topics for February, we report on the seminars for our contracted breeders, which are conducted as part of our CSR activity "Pets always come first Project," and introduce our "efforts against genetic diseases," which is one of the measures against intractable diseases in pets. ## February 2026 CSR Activity Topics: Holding Seminars for Breeders on Pet Genetic Diseases Under the concept of "Making all pets smile," our company has been engaged in the CSR activity "Pets always come first Project" since 2011. *1 As part of this, regarding "pet genetic diseases," we are promoting industry-academia joint research *2 in collaboration with veterinary universities and efforts aimed at eradicating genetic diseases. Genetic diseases are illnesses caused by mutations in genetic information inherited from parents, and more than 500 types have been confirmed in dogs and cats to date. Currently, in the entire pet industry, reducing the risk of occurrence of severe genetic diseases and proper management have become important issues. Our company has been working to support sound breeding that is less likely to produce pet genetic diseases by conducting direct transactions with sound breeders without intermediaries, and providing information sharing and advice through continuous dialogue. To further strengthen these efforts, since 2022, we have invited veterinarians and experts to regularly hold "Seminars for Contracted Breeders" to share knowledge on daily health management and breeding, including countermeasures against genetic diseases. We have held them 9 times so far, covering a wide range of themes such as breeding science and feeding management. For this 10th iteration, under the theme of "Pet Genetic Diseases," we held an online seminar in February 2026 titled "Basics of Pet Genetic Diseases and Latest Knowledge in Breeding." On the day of the event, Professor Osamu Yamato of the Joint Faculty of Veterinary Medicine, Kagoshima University, who is conducting joint research *3 on GM1 in Mame Shiba, was invited as a lecturer. He provided easy-to-understand explanations ranging from basic knowledge of pet genetic diseases to the mechanisms of autosomal recessive and dominant inheritance, the results of GM1 research in Mame Shiba, and the issues that need to be addressed in the field in the future.
