Shionogi's basic policy (SHIONOGI Group Heritage) is to always provide the best medicine (healthcare solutions) necessary to protect people's health. The Company engages in research and development, manufacturing, and sales activities of prescription drugs, over-the-counter drugs, and diagnostic agents. In 2020, the Company set forth the Vision (SHIONOGI Group Vision) that aims to achieve by 2030, "Creating the Future of Healthcare with a New Platform," and formulated the medium-term management plan Shionogi Transformation Strategy 2030 (STS2030) to realize this Vision. The Company is transforming into a Healthcare as a Service (HaaS) company that provides various healthcare services tailored to customer needs, not limited to the provision of prescription drugs, to comprehensively address the problems faced by patients and society worldwide.

From fiscal 2020 to fiscal 2022, the Company aimed to contribute to the early end of the COVID-19 pandemic by providing not only therapeutic drugs but also total care solutions for COVID-19, including detection (epidemic prediction), prevention, diagnosis, and mitigation of severe cases. As a result, the Company obtained domestic approval for the COVID-19 therapeutic drug Xocova at an unprecedented speed, advancing its drug discovery capabilities. Additionally, the Company expanded its product and service offerings beyond prescription drugs, including its first vaccine and wastewater epidemiology survey service. Based on the achievements and lessons learned from these efforts, the path to realizing the SHIONOGI Group Vision became clearer, leading to the revision of STS2030 in 2023 and the start of STS2030 Revision.

In STS2030 Revision, the three years from fiscal 2023 to fiscal 2025 are positioned as STS Phase 2, with the basic policy of global top-line growth centered on the infectious disease area and fostering growth drivers through aggressive investment, accelerating growth through transformation. In research and development, the Company focuses on high-impact infectious diseases and high-impact QOL diseases as priority areas. In infectious diseases, the Company has developed many innovative new drugs, such as the anti-HIV drugs (dolutegravir and cabotegravir), the  for multidrug-resistant Gram-negative bacterial infections (cefiderocol), and the anti-influenza virus drug Xofluza, based on its strong foundation in small molecule drug discovery (creating drugs with molecular weights ranging from tens to hundreds). The Company aims to solve the problems faced by patients and society worldwide by further strengthening and expanding its strong foundation in small molecule drug discovery.

On the other hand, JT Pharmaceutical Business has been engaged in research and development of prescription drugs since entering the business in 1987, aiming to create first-in-class small molecule drugs through stable research and development investment. Currently, under the business purpose of "valuing science, technology, and human resources and contributing to patients' health," Japan Tobacco conducts research and development, while Torii Pharmaceutical handles manufacturing, sales, and promotion activities, building an integrated value chain and maximizing synergies within the group. JT Pharmaceutical Business focuses on three priority research and development areas: cardiovascular, renal, and muscle, "immunology and inflammation, and central nervous system, with strengths in rapid clinical development through specialization on research and development in the small molecule drug discovery and collaboration between domestic and international research and development bases. To deliver new drugs created in-house to patients as early as possible, JT Pharmaceutical Business actively engages in out-licensing and partnerships with global mega-pharma companies, in addition to promoting in-house development.

Shionogi has been considering collaboration with JT Pharmaceutical Business and Torii Pharmaceutical to realize the Vision of "Creating the Future of Healthcare with a New Platform" in STS2030 Revision. As a result of these considerations, the Company concluded that by adding the capabilities of JT Pharmaceutical Business, which has strengths in small molecule drug discovery and development, it would be possible to accelerate the  advancement of promising pipeline projects and  increase the responsiveness and efficiency of business operations through collaboration with the Company's pharmaceutical manufacturing functions. The Company proposed to Japan Tobacco the acquisition of JT Pharmaceutical Business and the full ownership of Torii Pharmaceutical, and after subsequent discussions, reached the Agreement. The Company believes that the Transaction will create a leading company that delivers innovative pharmaceuticals from Japan to the world, contributing to the health of patients and people worldwide, and contributing to the realization of a sustainable and healthy society. The Company also believes that the Transaction will provide opportunities for the employees of JT Pharmaceutical Business (including group companies) to continue to thrive with peace of mind.
