Top 10 female CEOs of the Fortune Global 500
Just 24 companies in the Global 500 – which ranks firms by their worldwide revenue – are led by female CEOs.
This, nevertheless, represents an all-time high when it comes to female leadership in Fortune’s annual list, which has been compiled every year since 2014.
But just who are these powerful, trailblazing women and how have they made their mark on the world of business?
Here, Business Chief takes a look at the top 10.
1. Karen Lynch - CVS Health (company ranked 10 in Global 500)
Rightly regarded as one of the world’s most influential businesswomen, Karen Lynch became CEO at CVS Health back in February 2021, when she succeeded long-term chief Larry Merlo.
Lynch boasts more than 30 years of experience in the healthcare industry, having held executive positions at Cigna and Magellan Health Services.
After joining CVS, she served as Executive Vice President and as President of the company’s Aetna arm.
Fortune has ranked her as the world’s most powerful woman in business for the last two years.

You have to jump down to number 25 on the Global 500 to find another female-led company.

She now serves as co-CEO of the company, alongside Bo Yao and Yonglin Xie.
3. Rosalind Brewer - Walgreens Boots Alliance (45)

In 2019, this trailblazer had already become the first Black woman to sit on Amazon’s board.
Brewer’s rise to the top is all the more impressive when you consider she was a first-generation college student who subsequently started her working career as a chemist at Kimberly-Clark.
