Aston Martin said Chairman Lawrence Stroll's Yew Tree Consortium had further increased its stake in the British luxury automaker by 3.27 percent to 26.23 percent.
Yew Tree, which bought an additional 26 million ordinary shares of the company, was already its largest stakeholder, followed by Saudi Arabia's Public Investment Fund (PIF) and Chinese automotive firm Geely.
Aston Martin has had a tough time since floating in 2018. Stroll took over as chairman of the company in 2020.
The company has been more upbeat about its outlook more recently and plans to bolster cash and margins by rolling out next-generation sports cars and limited editions in the second half of 2023.
