Amazon shareholders rejected a proposal to separate the roles of CEO and board chair.

According to a filing on Thursday, around 82% of shareholders voted against the measure.

This independent proposal, along with seven others, was put forward at Amazon’s annual meeting on Wednesday, but all were ultimately rejected.

The proposal aimed to formalize this structure at Amazon, similar to most S&P 500 companies, according to advocacy group the Accountability Board.

The group argued that separating the roles enables the board to concentrate on corporate governance and oversight, while the CEO can focus on running the business.

“With the positions currently separated, now would be an opportune time to do so,” the proxy states.

Shareholder proposals to separate the board chair and CEO roles have surged recently, increasing by 113% among Russell 3000 companies in the first half of 2023—the highest in a decade, according to the Harvard Law School Forum on Corporate Governance.

Amazon encouraged shareholders to oppose the proposal, stating that its current policy allows the board to choose the best leadership based on the company’s specific circumstances at any given time.

“In light of our success through these various leadership structures, the board believes that shareholders are better served by the board retaining the ability to adapt to our evolving needs and implement the optimal leadership structure at any given time,” Amazon wrote in the filing.
