This year the Company will continue to accelerate development of relevant products in this field, expand layout, increase product scale, promote business development, and further explore the new blue ocean of industrial microbiology. In February 2022, Sinclair, the Company’s wholly-owned subsidiary in the United Kingdom, completed the acquisition of 100% equity of Viora, an energy-based aesthetic devices company, and 7 The First Quarterly Report 2022 of Huadong Medicine Co., Ltd. officially included it into the Company’s consolidated statements. Viora has advanced product portfolios with technologies like laser, intense pulsed light, radio frequency, high-pressure jet and microdermabrasion. Its Reaction, V series (V10, V20, V30), EnerJet and Pristine and Infusion are currently sold overseas. In 2015, Reaction was granted the registration certificate of Class III medical devices by the National Medical Products Administration (NMPA). Viora’s products can effectively complement the Company’s existing energy-based product line, so the Company will have business layout in all types of energy-based aesthetic medical devices. Through efficient integration, High Tech will make full use of the channel resources accumulated by Viora to expand the U.S. market. Based on the acquisition, the Company has creatively put forward the product concept of “V Women Tech” that focuses on professional care for women with leading aesthetic medical technology.

It turned around year on year and realized operating profit for the first time in history. After acquiring Viora, Sinclair has continued to implement operation integration. With a good number of orders in hand for the second quarter, it is expected to maintain the rapid growth trend on the whole, making a good start for the subsidiary to maintain rapid growth in operating income throughout the year and realize the first annual operating benefit since the subsidiary completed acquisition. During the reporting period, the Company’s domestic wholly-owned aesthetic medicine company Sinclair (Shanghai) realized operating income of RMB157 million and demonstrated strong profitability, which exceeded the contribution of Huadong Ningbo’s agency business income to the Company’s profit in the same period last year.

Currently it has signed a cooperation agreement with more than 400 hospitals, and has more than 700 certified doctors. Since its launch, Ellansé has maintained great market attention, enjoyed good reputation, and led the regenerative aesthetic medicine market. The subsidiary has actively launched the genuine product traceability campaign. It has included aesthetic medicine institutions that sell the unofficially certified products 8 The First Quarterly Report 2022 of Huadong Medicine Co., Ltd. into its cooperation blacklist and released it to the public, to urge beauty seekers to enhance self-protection awareness and protect their legal rights and interests.

After buying a care program online, consumers choose offline contracted cooperative institutions to provide specific services. By standardizing the purchase and consumption procedures, the Company has made prices transparent, thus providing consumers with high-quality services. Besides, the Company will take over Reaction (used for body and face shaping and skin firming), a product of Viora that has already been on the domestic market, and plans to integrate domestic EBD market resources and channels to realize resource coordination and sharing and actively promote the rapid growth of the product in the domestic market. 2.
