Former Vice President Al Gore will retire from Apple’s board of directors next month after more than 20 years with the company.

In a filing with the U.S. Securities and Exchange Commission (SEC), Apple announced Gore, along with former Boeing CEO James Bell, will retire during the company’s 2024 annual shareholder meeting next month.

The board has a policy that directors generally can no longer stand for reelection to the board after reaching the age of 75 years old. Gore and Bell turned 75 last year.

“We’re deeply grateful to Al and James for their many years of service to Apple — their insights, energy, and values have made us a stronger company in so many ways,” Apple CEO Tim Cook said in a statement.

“For more than 20 years, Al has contributed an incredible amount to our work — from his unconditional support for protecting our users’ privacy, to his incomparable knowledge of environment and climate issues,” Cook continued.

Gore joined Apple’s board of directors in 2003 and currently owns 468,995 shares of Apple, which is valued at about $87 million. His total compensation on the board in 2023 was $376,894, including $100,000 in fees earned and $275,022 in stock awards, according to the filings.

Gore serves on the board’s people and compensation committee, along with its corporate governance committee, per the SEC filings.

Bell owns about 38,527 shares of company stock worth more than $7 million. He joined the board in 2015 and serves on the board’s audit and finance committee.

Apple on Thursday announced it nominated Dr. Wanda Austin, the former president and CEO of The Aerospace Corporation, for election to the company’s board of directors.
