  随着一场延宕近十年的控制权之争再度升级,在新冠疫情期间因早期推出灭活疫苗而备受瞩目的科兴控股生物技术有限公司(NASDAQ:SVA ,下称“科兴生物”)走上风口浪尖。这次外界关注的焦点首先是新冠疫苗生意2021年以来的巨额“红利”如何分配。

As a near-decade-long battle for control escalates once again, Sinovac Biotech Ltd. (NASDAQ: SVA), which rose to prominence during the COVID-19 pandemic for its early rollout of inactivated vaccines, has found itself back in the spotlight. This time, much of the external scrutiny centers on how to divide the enormous "dividends" generated by the company’s COVID vaccine business since 2021.

  北京时间7月9日8时,一场特殊的股东大会在加勒比岛国安提瓜和巴布达Stapleton律所的办公室和线上同步举行:科兴生物董事长李嘉强宣布开会,旋即宣布休会。随后,股东们在董事卢毓琳主持下召开续会,并投票罢免了李嘉强任董事长的董事会,重组了由科兴生物股东赛富基金提名的十人董事会。

At 8:00 a.m. Beijing time on July 9, an unusual shareholders’ meeting took place both in-person at the offices of Stapleton Law in Antigua and Barbuda, and online. Sinovac Biotech’s chairman, Li Jiaqiang, opened the meeting and immediately announced an adjournment. Afterward, shareholders, under the chairmanship of director Lu Yulin, reconvened the meeting, voted to remove Li Jiaqiang’s board, and installed a new 10-member board nominated by Sinovac Biotech shareholder, SAIF Partners.

  会议结果不被李嘉强主导的董事会接受,称休会后其他人无权也没有法律基础“重新召开”会议,即他们和十人董事会互不认可,都认为自身才具备合法性。究竟孰是孰非,与巨额“红利”分配关系密切——谁是合法股东,谁有权主导分红?这背后又涉及跨中、美、安提瓜和巴布达、英国等多个国家的诉讼和纷争。

The results of the meeting were not accepted by the board of directors led by Li Jiaqing, who stated that no one else had the authority or legal basis to "reconvene" the meeting after adjournment—in other words, the two sides and the ten-member board do not recognize each other, each claiming legitimacy. At the heart of the dispute, closely tied to the distribution of massive "dividends," is the question of who the legitimate shareholders are and who has the right to lead the dividend allocation. The issue is further complicated by lawsuits and disputes spanning China, the United States, Antigua and Barbuda, the United Kingdom, and other countries.
