Amdocs Limited (DOX)

Wie das Geld verdient wird

The larger and more stable part of revenue is managed services: Amdocs keeps operating a carrier's billing and network systems on an ongoing contract, which produces recurring, multi-year revenue. The rest comes from project work — building, upgrading or migrating these systems — which is billed as the work is done and is more irregular. Because switching a telecom operator's billing platform is a multi-year undertaking, contracts tend to run for years once signed.

A telecom operator's billing and customer-management systems touch every subscriber and every invoice, so replacing them is a multi-year, high-risk project most carriers avoid unless forced to. That inertia favors the incumbent vendor, but it is not exclusive to Amdocs: rival providers run the same kind of systems for other large carriers and can win a contract when one comes up for renewal.

Telecom operators must keep billing and serving subscribers regardless of the economic cycle, which supports the managed-services base of Amdocs' revenue. The project-based work that upgrades or migrates systems is more discretionary and can be delayed when a carrier tightens its own capital spending.

Wichtigste Risiken

• Revenue concentrated in a few telecom carriers — A small number of large customers, led by AT&T and T-Mobile, account for a very large share of revenue. Losing or scaling back business with any of them would be difficult to replace.
• Consolidation among telecom operators — Mergers among telecom carriers reduce the number of potential customers and can put existing contracts up for renegotiation when two customers combine their systems.
• Long, complex projects can run over budget — Large system builds and migrations for telecom operators are technically complex and multi-year; delays or cost overruns on fixed-price engagements can hurt margins.
