On the evening of May 12, Ms. Nguyen Thi Son - founder of Son Kim Group and also mother-in-law of Mr. Ho Nhan - shared a status on social media, commemorating her son-in-law: "I know you are a young man with many ambitions in your career, with many wishes to contribute to society, and you have proven that you can do it... Goodbye son-in-law Ho Nhan".
According to research, Mr. Ho Nhan was born in 1966, is a Vietnamese American, grew up in New York, and graduated with a PhD in biotechnology from the University of Arizona (USA).
Before returning to Vietnam to settle down in 2006, he had nearly 20 years of research and work in the international biomedical industry, participating in many mergers and acquisitions in the pharmaceutical, hospital and medical equipment sectors.

He also led the healthcare stock valuation team of an investment fund in Hong Kong (China), with a scale of up to billions of USD.
In September 1997, Mr. Ho Nhan founded Nanogen Pharmaceutical Biotechnology Joint Stock Company and held the role of Chairman of the Board of Directors and General Director for many years. He is known as the "father" of the Nanocovax vaccine - one of the first Covid-19 vaccine candidates researched and developed by Vietnam.
Under his leadership, Nanogen rapidly expanded its scale. By the end of 2019, the company's total assets reached more than VND 1,369 billion. In the initial stage, Mr. Ho Nhan owned 70% of the shares, his wife, Ms. Nguyen Thi Hong Van, held 25%, and the remaining 5% belonged to Mr. Ho Vu Thanh. However, the ownership structure gradually changed with the participation of foreign investors.
In May 2019, Nanogen's charter capital increased from VND698.75 billion to VND715 billion thanks to the offering of shares to foreign shareholders, increasing the ownership ratio of this group from 16.28% to 25.68%.
By March 2021, the company continued to increase its capital to VND 806.25 billion. At this time, only Mr. Ho Nhan and his wife were founding shareholders, of which Mr. Nhan held about 59.6% of the shares (equivalent to VND 480.5 billion), Ms. Van owned 14.6% (equivalent to VND 117.8 billion). Foreign shareholders included 9 organizations and individuals - of which KIS Vietnam Securities Company held 0.2% of the charter capital.
In its 2020 semi-annual report, KIS Vietnam valued its investment in Nanogen at VND11.6 billion, estimating that the company's value could reach about VND5,099 billion if it successfully develops the Covid-19 vaccine. However, Nanocovax has not yet been officially licensed for circulation.
According to updated information on the National Enterprise Information Portal, from December 29, 2021, Mr. Ho Nhan is no longer the legal representative of Nanogen. The positions of Chairman of the Board of Directors and General Director were transferred to Ms. Nguyen Thi Hong Van - Mr. Nhan's wife, currently the General Director and legal representative of the company.
However, Ms. Nguyen Thi Son shared with the media and said that Mr. Ho Nhan is still the Chairman of the Board of Directors of Nanogen.
Ms. Nguyen Thi Hong Van is the eldest daughter of the Son Kim family. She is the daughter of Ms. Nguyen Thi Son - the founder of Dai Thanh, a famous textile and garment enterprise since the 1950s.
Later, the third generation of the family developed into SonKim Group (since 1993), expanding its operations into real estate, retail and media, managing many international brands in the Vietnamese market.
In addition to the biotechnology sector, Mr. Ho Nhan also participates in financial investment. He was a member of the Board of Directors of Vina Securities Company (VinaSecurities) from April 2013 to September 2017. He was also a major shareholder of One World Services Joint Stock Company (ONW), owning up to 15.8% of shares as of November 2016.
