Regencell Bioscience Holdings Limited Releases CEO Letter to Shareholders

Regencell Bioscience Holdings Limited (NASDAQ:RGC) ("Regencell" or the "Company"), an early-stage bioscience company today released a letter from Yat-Gai Au, Founder and Chief Executive Officer of the Company.

Dear Shareholders:

As CEO of Regencell, I am pleased to take this opportunity to discuss the significant milestones we achieved thus far in 2021, update our shareholders on our business plan for the remainder of the year and discuss our goals for 2022 and beyond.

For those who are new to Regencell, the Company focuses on the research, development and commercialization of Traditional Chinese Medicine ("TCM") for the treatment of neurocognitive disorders and degeneration, specifically Attention Deficit Hyperactivity Disorder ("ADHD") and Autism Spectrum Disorder ("ASD").

We have been researching and conducting studies to address the fundamental causes of ADHD and ASD disorders. Our goal is to improve the lives of ADHD and ASD patients, their families and caregivers and become a market leader for the treatment of these disorders. We aim to achieve improvements in both symptoms and overall health of patients as compared to currently available medications in the market. We are passionate about transforming the lives of patients, their families and caregivers and help them feel their best physically, mentally and emotionally!

Nasdaq Listing

On July 16, 2021, our ordinary shares began trading on the Nasdaq Capital Market. We raised net proceeds of approximately $19.3 million from the initial public offering of 2,300,000 ordinary shares at a public offering price of $9.50 per share. We plan to use these proceeds to fund our second research study, TCM formulae and products, staff salaries, product and intellectual property registrations, facilities rental, renovations and equipment, for working capital and other general corporate purposes.

Research Studies

Our first study using personalized TCM formula in Hong Kong showed a drop in assessment scores meaning that ADHD and ASD symptoms were less severe for patient who participated in the study. However, there is no assurance that we can expect similar outcome in our second research study.

Encouraged by this positive outcome, we plan to commence our second research study next month in Hong Kong, which is expected to last for approximately one year. Approximately 100 patients will participate in our second research study, in 3-12 months treatment cycles. Our goal for the second research study is to verify the effectiveness of the standardized TCM formulae with candidates that are experiencing mild, moderate and severe ADHD and ASD conditions. Once completed, the research study will provide the foundation for the Company to apply for a proprietary Chinese medicine ("pCm") registration in Hong Kong. We look forward to sharing the outcome as soon as we complete the study.

During a short period of time, we have achieved significant milestones, and these could not have been achieved without the tremendous backing of our long-time supporters. Speaking on behalf of our entire management team and board of directors, I would like to extend my thanks and deepest gratitude to:

Mr. Samuel Chen and Mrs. Fiona Chen, Dr. Hai Ping Jin and Mr. Jay Lee for their contribution and support to our research. Their investment gives hope to ADHD and ASD patients, their families and caregivers in need of a solution.

Also, Mr. Sik-Kee Au, our strategic TCM research partner, for offering his 30+ years of experience in TCM research & development, and clinical practice. Our partnership with Mr. Au has been instrumental in conducting our studies and has given us the exclusive rights and ownership of all his TCM formulae and the intellectual property rights of the TCM formulae.

Last but not least, I would like to thank all of our business partners, professionals and investors for making this possible, and to our team for the amazing work they continue to do every day.

Respectfully,
