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)
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.
2. Sin Yin Tan - Ping An Insurance (25)
You have to jump down to number 25 on the Global 500 to find another female-led company.
Hailing from Singapore, Sin Yin Tan holds bachelor’s degrees in electrical engineering and economics, as well as master’s degrees in both electrical engineering and computer science – all from the Massachusetts Institute of Technology (MIT).
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.
4. Gail Boudreaux - Elevance Health (50)
She moved across to health insurance provider Anthem in 2017 to become the company’s CEO.
The firm, which has since rebranded to Elevance, has almost 50 million members and serves in excess of 115 million through its affiliated companies.
5. Mary Barra - General Motors (64)
Her appointment also earned her a place among TIME’s 100 Most Influential People in the World.
Barra, who is of Finnish descent, has built up decades of experience at GM and served in various high-profile positions.
Under her stewardship, the firm has invested billions in electric vehicles and self-driving cars, while also topping rankings for gender balance in the workforce and pay equity.
6. Sarah London - Centene (66)
Initially serving as Senior Vice President of Technology Innovation and Modernization, London assumed a raft of responsibilities as she progressed to becoming Vice Chairman.
Last year, she went one further as she was appointed CEO.
7. Carol Tomé - UPS (97)
Carol Tomé has spent her career working for some of the world’s biggest companies.
Having started out as a Commercial Lender with United Bank of Denver (now Wells Fargo), Tomé became Director of Banking at Johns-Manville Corporation, and then Vice President and Treasurer at Riverwood International Corporation.
She took up the same positions with Home Depot in 1995, before moving up the ladder to become Executive Vice President and Chief Financial Officer – helping to establish the firm as one of the world’s largest retailers.
Joining UPS made Tomé the 12th CEO in the company’s 115-year history.
8. Catherine MacGregor - ENGIE (130)
Over three decades, Catherine MacGregor has dedicated her entire career to the energy sector, managing numerous complex industrial projects.
MacGregor first spent 23 years at Schlumberger, the world’s leading provider of reservoir identification, drilling, production and processing technologies for the oil and gas industry.
She then headed up the Technip Energies entity of oil services company TechnipFMC from 2019 to 2020.
MacGregor has been CEO at the ENGIE group since the start of 2021.
9. Jane Fraser - Citigroup (141)
What’s more, Fraser is the first woman in history to run a major Wall Street bank.
The long-serving executive first joined Citi in 2004, going on to lead functions including corporate strategy and mergers and acquisitions.
Hailing from Scotland and a graduate of the University of Cambridge, Fraser previously served as president of Citigroup and CEO of Global Consumer Banking.
10. Alka Mittal - Oil and Natural Gas (190)
Mittal became the first woman to ever lead ONGC as its CMD when she was appointed in January last year, succeeding Subhash Kumar following his retirement.
She has been credited over the years with implementing the National Apprenticeship Promotion Scheme in the ONGC, bringing on board more than 5,000 apprentices.
Mittal has also played a key role in ensuring employees can expect a safe working environment, especially women and engineers at offshore platforms and remote locations.
