Citigroup is a global financial powerhouse that orchestrates the movement of $5 trillion in daily transaction volume, serving as the essential connective tissue for the world's most complex multinational corporations. The firm remains a leader on the global stage, servicing 90% of the Fortune 500 through a proprietary network that includes direct membership to over 270 cash-clearing centers and a footprint that spans 94 countries. After a checkered history operating as an overly complex, disjointed firm, steps have been taken to streamline operations, resulting in organization across five segments: services, markets, banking, wealth, and US personal banking.

Deutsche Telekom merged its T-Mobile USA unit with prepaid specialist MetroPCS in 2013, and that firm merged with Sprint in 2020, creating the second-largest wireless carrier in the US. T-Mobile now serves about 86 million postpaid and 26 million prepaid phone customers, equal to around 30% of the US retail wireless market. The firm entered the fixed-wireless broadband market aggressively in 2021 and now serves 8 million residential and business customers with its wireless network. It also serves 1 million fiber broadband customers through joint ventures with fiber network owners. T-Mobile owns a stake in these firms, which provide wholesale access to their networks. In addition, T-Mobile provides wholesale services to wireless resellers.
