Analysis · TANH · Industrial Applications And Services
The reclassification of Tantech Holdings' common shares into Class A and Class B, with Class B shares carrying 50 times the voting power of Class A shares, represents a material change in the company's corporate governance structure. While both classes maintain equal economic rights, this move effectively entrenches control with holders of Class B shares, typically founders or insiders. This concentration of voting power can reduce the influence of public shareholders and is generally viewed negatively by investors concerned with corporate governance and shareholder rights.
