Stephen J. Squeri became Chairman and Chief Executive Officer of American Express in February 2018, succeeding Kenneth Chenault after a carefully planned succession. His appointment marked the continuation of American Express's tradition of promoting from within, having spent over 30 years at the company.

Squeri joined American Express in 1985 and held various leadership positions across the organization. Before becoming CEO, he served as Vice Chairman, responsible for the company's technology, digital, and data capabilities—experience that proved invaluable as the company accelerated its digital transformation.

Under his leadership, American Express has focused on three strategic priorities: expanding the customer base beyond traditional affluent segments to include younger consumers, investing heavily in digital capabilities and mobile experiences, and strengthening the company's position in the small business market.

His tenure has been marked by resilience through crisis. During the COVID-19 pandemic, Squeri led the company through unprecedented challenges in the travel and entertainment sectors—core spending categories for American Express cardmembers. The company emerged stronger, with record revenues in 2023 and continued growth in card acquisitions.

Squeri has also emphasized the importance of corporate culture and employee development, maintaining American Express's reputation as one of the best places to work in financial services.
