Amdocs

Amdocs earns revenue through long-term managed-services contracts and software licensing with communications providers. The firm designs, deploys, and operates billing support systems, network inventory platforms, and digital customer-experience suites. Its fiscal 2023 revenue reached $4.89 billion, according to the company's own published key stats.

In May 2026, Amdocs launched aOS, an agentic operating system that layers a generative-AI cognitive core on top of a carrier's existing BSS and OSS stacks. The product is pitched as a cross-stack intelligence layer that can automate network operations and accelerate customer-facing 5G use cases — a direct move to capture the GenAI capex currently flowing through telecom IT budgets.

Publicly announced customers include AT&T, Telefónica, Three UK, Globe, PLDT, Etisalat by e&, and Telia Finland. Amdocs states on its website that it serves over 350 communications and service-provider customers in 85 countries, with managed-services agreements that often stretch across multiple years of IT and network modernization.

Yes — while telecom dominates the revenue base, Amdocs also runs a financial-services practice aimed at helping banks adopt new technologies, and it manages relationships with over 850 content creators to serve roughly 500 video distributors. These verticals remain smaller than the core communications business.

The company maintains a globally distributed workforce of approximately 29,000 employees. Key development centers include offices in Ra'anana, Israel, Pune and Mumbai, India, Ottawa and Mississauga, Canada, and multiple European locations in London, Paris, and Madrid.
