Notice of Conclusion of Joint Venture Agreement Regarding the Establishment of a Joint Venture for Contract
Development and Manufacturing of Active Pharmaceutical Ingredients and Intermediates

The six companies of Shionogi Pharma Co., Ltd. (headquartered in Settsu, Osaka; President & CEO: Ryuichi Kume;“Shionogi Pharma”), Chiyoda Corporation (headquartered in Yokohama, Kanagawa Pref.; President: Masaji Santo;“Chiyoda”), Taisei Corporation (headquartered in Shinjuku-ku, Tokyo; President &CEO: Yoshiro Aikawa; “Taisei”),Fujimoto Chemicals Co., Ltd. (headquartered in Chuo-ku, Osaka; President & CEO: Kazumasa Fujimoto; hereinafter“Fujimoto Chemicals”), Takenaka Corporation (headquartered in Chuo-ku, Osaka; President: Masato Sasaki;“Takenaka”), and Nagase & Co., Ltd. (headquartered in Chuo-ku, Tokyo; Representative Director and President: KenjiAsakura; “Nagase”) are pleased to announce that we have concluded a joint venture agreement regarding theestablishment of a joint venture (hereinafter the “joint venture”) to develop a technology for Continuous Manufacturing(CM) of active pharmaceutical ingredients (APIs) and intermediates and to conduct a contract development andmanufacturing business using CM technology.
1.

Purpose of the establishment of the joint venture
The environment surrounding APIs and intermediates is undergoing major changes. Under such circumstances, it isnecessary to establish an advanced quality control system and thoroughly control the regulated substances in response totightened laws and regulations, as well as to strengthen the ability to offer globally competitive prices and meet delivery
dates. Furthermore, it is also desired to establish a sustainable manufacturing method that takes into consideration theprotection of workers in the handling of chemical substances, energy saving and environmental protection. Especially
under the COVID-19 pandemic, which has raged on since last year, it is also required to further accelerate pharmaceuticaldevelopment and build a stable supply network for APIs. By introducing CM technology*1 in response to theseenvironmental changes, it is expected that the time required for development of manufacturing methods in thepharmaceutical development stage will be shortened. CM technology is also expected to improve the efficiency ofcommercial production of pharmaceutical ingredients by conserving manpower and space and to enable advanced quality
assurance for high-quality pharmaceutical products. Aiming to realize effective CM of APIs and intermediates, the six
companies with specialized technologies and functions have come together to establish the joint venture to provide
contract development and manufacturing services of APIs and intermediates. The joint venture is to be established as per
the “Agreement between Chiyoda Corporation and Shionogi Pharma on the Development of Continuous Manufacturing
Technology for APIs and Intermediates and to Study the Establishment of a Joint Venture for commercialization of thetechnology,” announced in the press release dated May 31, 2021.
2.

Outline of the joint venture
The joint venture will provide full-range, one-stop manufacturing services of APIs and intermediates, from manufactureof APIs for clinical trials to commercial production. In order to meet diverse customer needs, Shionogi Pharma willtransfer to the joint venture the business of manufacturing APIs for clinical trials using GMP- and USP/EP/JP-compliant
batch manufacturing technology*2 with a proven track record, aiming to conduct pharmaceutical development andmanufacturing using both CM technology and the already well-established batch manufacturing technology. This will
make it possible to apply CM to the processes that will have significant benefits by switching to CM. In addition, byapplying CM from the development stage, it is also possible to accelerate the development of pharmaceutical products
while ensuring high quality and process safety.
By actively developing technologies and introducing new technologies through strengthened industry-governmentacademia collaboration and cooperation with various partner companies, including invested companies, we will strive toexpand our business and provide CM-based contract development and manufacturing services ahead of the rest of theworld, thereby promoting an API manufacturing revolution.
Currently, we are also conducting discussions with one of our partner companies, Yokogawa Electric Corporation(headquartered in Musashino City, Tokyo), regarding the development of CM technology for APIs and intermediates.
<Reference information> Benefits of the introduction of CM

Shortened development period by reducing time for process development due to no need for scale-upImproved success rate for drug development process through accurate control of minute impurities (thosesubject to ICH M7, etc.)

Reduced human errors and improved productivity through automation and manpower saving by introducing
quality control tools that enable continuous inline quality monitoring (PAT*3, RTRT*4, etc.)Improved drug quality by removing nonconforming products based on RTD*5

Reduced construction costs of manufacturing plants due to compact size of equipment, and improved
productivity through introduction of IT systems, including quality control toolsEasier to own multiple production bases, enabling stable supply and diversification of production risksReduced risks for workers through containment, and contribution to green chemistry by reducing waste andenvironmental impacts*1 A manufacturing method in which a certain amount of raw materials or their mixtures are continuously fed into the manufacturing process,and products are continuously removed from the process after a certain period of time.
*2 A conventional manufacturing method in which all or part of the raw materials are fed discontinuously into the manufacturing equipment,and products are removed all at once after the completion of each step.
*3 PAT: Process Analytical Technology*4 RTRT: Real Time Release Testing*5 RTD: Residence Time Distribution
