We owe this significant milestone to everyone who has supported the Company and N-NOSE® to date. With gratitude and a desire to provide more people with an opportunity to become interested in their own health status, we will be holding a "10th Anniversary & 1 Million Cumulative Samples Double Commemorative Campaign" starting July 1, 2026 (Wed). ■ Milestones: 10th Anniversary and 1 Million Cumulative Samples Since our founding in 2016, the Company has been advancing research and development focused on the superior olfactory abilities of nematodes, with the aim of "making it easier for everyone to know their health status." We interpret surpassing 1 million cumulative samples in five years since full-scale sales began as a result of many people taking an interest in their health and choosing N-NOSE® as the first step towards healthy behavior. Furthermore, the achievement of 1 million cumulative samples is a testament to the trust placed in us by many people and is a great asset to our company. We will continue to strive for a society where everyone can routinely check their health status through research and development that leverages the abilities of living organisms. ■ "10th Anniversary x 1 Million Cumulative Samples Double Commemorative Campaign" Outline with Gratitude ● Period: July 1, 2026 (Wed) - September 30, 2026 (Wed) ● Content: A "3,000 yen discount coupon" will be distributed, usable when purchasing an N-NOSE® test kit. ● Target Prices (including tax): ○ Standard Test Course: Regular price \19,800 \Rightarrow \16,800 ○ Regular Check-up Course: Regular price \16,800 \Rightarrow \13,800 (\*First application only) ■ Comment fr
