ADTRAN Holdings, Inc. develops and provides open, disaggregated networking and communications solutions that enable voice, data, video, and internet communications across various network infrastructures. The company operates through two primary segments: Network Solutions and Services & Support. The Network Solutions segment generates the vast majority of the company's revenue (typically over 80%) and includes hardware and software products spanning Subscriber Solutions, Access & Aggregation Solutions, and Optical Networking Solutions. The Services & Support segment provides network design, implementation, maintenance, and cloud-hosted software-as-a-service (SaaS) applications like Mosaic One.
Geographically, ADTRAN has a strong footprint in the United States and Europe, significantly bolstered by its 2022 business combination with Germany-based ADVA Optical Networking SE. This merger expanded ADTRAN's capabilities beyond the access network into core and metro optical networks, allowing it to offer end-to-end fiber networking solutions. The company serves a diverse customer base that includes large and small service providers, alternative service providers (such as utilities and municipalities), cable/MSOs, and distributed enterprises. ADTRAN's competitive position is driven by its comprehensive fiber portfolio, its focus on software-defined access, and strategic opportunities to replace high-risk legacy vendors in European and North American communications networks.
