ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” “ADTRAN” or the “Company”) today announced its unaudited financial results for the first quarter ended March 31, 2026.
Adtran today announced a new phase in its long-standing partnership with GLDS, delivering billing-driven, zero-touch automation for subscriber lifecycle management. As broadband and managed Wi-Fi services scale, manual hand-offs between billing, OSS and in-home networking systems are no longer sustainable. By enabling GLDS BroadHub® to orchestrate subscriber creation, service activation and ongoing lifecycle changes across access and the connected home, the solution streamlines operations, accelerates time to revenue and reduces operational complexity. This approach gives broadband providers greater control as subscriber expectations rise and service models evolve.
Adtran today announced that its service delivery gateway (SDG) carrier-grade router portfolio has received conditional approval from the FCC’s Public Safety and Homeland Security Bureau, formally exempting the platforms from FCC Covered List restrictions through October 1, 2027. The decision places Adtran among the first router manufacturers to achieve this designation under the FCC’s national security review process. By ensuring continued access to Adtran’s SDG technology, the approval enables service providers to maintain deployment momentum, reduce operational risk and invest confidently in the long-term expansion of broadband networks while navigating evolving regulatory requirements.
Adtran today announced two wins at the FTTH Innovation Awards 2026, recognizing its leadership across in-home connectivity and AI‑driven network operations. The company received awards in the categories for ‘Active infrastructure – home network’ and ‘Artificial intelligence (AI), machine learning and other software.’ Organized by FTTH Council Europe, the annual awards honor technologies that advance fiber deployment while improving scalability, operational efficiency and user experience. Voted by FTTH Conference 2026 speakers, the results reflect peer recognition for Mosaic One Clarity and Adtran’s SDG 8000 and 9000 Series mesh Wi‑Fi solutions, both designed to address real deployment, performance and operational challenges facing service providers as fiber footprints expand.
ADTRAN Holdings, Inc. (NASDAQ: ADTN and FSE: QH9) (“ADTRAN Holdings” or the “Company”) announced today that the Company will release its financial results for the first quarter 2026 after the market close on Monday, May 4, 2026, at https://investors.adtran.com/. The Company will conduct a conference call on Tuesday, May 5, 2026, to discuss the results for the quarter.
Adtran today announced that ProRail, the operator of the Dutch railway network, has deployed its ALM in‑service fiber monitoring solution to protect the integrity of its nationwide fiber infrastructure. The technology supports critical ICT systems used for timetabling, incident management, maintenance and new construction planning. With real‑time insight into fiber health across its 4,600km backbone network, ProRail can identify and address issues before they impact rail operations. This approach reflects a growing demand for in‑service fiber assurance across large‑scale transport and other critical infrastructure networks. The deployment was delivered in collaboration with TrueCom, a specialist in critical network and fiber optic infrastructures.
Adtran today launched its Ensemble Cloudlet multi‑node solution, a high‑availability edge platform that supports AI inference and agentic AI deployments where low latency, resilience and secure local processing are critical. Removing the complexity and cost barriers that slow modern service and enterprise deployments, the solution creates a single, logical cloud with distributed storage and automated failover, starting with just two nodes. Built on Cloudlet OS and managed through Ensemble EdgeView orchestration, it enables zero-touch deployment and unified lifecycle management, providing a simple, scalable foundation for running networking, IT and emerging AI workloads at the edge.
Adtran today extended its edge routing portfolio with new Terabit-class edge routers, featuring 400Gbit/s interfaces. These new devices give operators a practical, cost-effective way to scale capacity at the network edge without adding space, power or operational burden. Supported by a unified software foundation that simplifies deployment and operations across the portfolio, the solutions provide a consistent, future-ready environment for edge growth. With 100Gbit/s interfaces now widely deployed across fiber access, aggregation and mobile backhaul, operators need higher-capacity edge options that reduce cost, complexity and inventory sprawl. Unlike traditional monolithic platforms, Adtran’s new Terabit-scale edge solution with 400Gbit/s interfaces combines compact, energy-efficient, cabinet-ready designs with optional optical integration for even greater levels of scale and signal amplification.
Adtran today announced that it will showcase its latest optical innovations at OFC 2026, taking place from March 15 to 19 in Los Angeles. The company will outline how intelligent, secure and power‑efficient optical networks are shaping the next phase of AI infrastructure.
Adtran today announced it’s playing a key role in the OIF’s multi-vendor interoperability demo at OFC 2026. The showcase brings together 40 member companies, highlighting real‑world operation across open optical networks. It validates multi‑vendor 100Gbit/s, 400Gbit/s and 800Gbit/s ZR+ coherent pluggable transceivers operating over open line systems. Featuring Adtran’s FSP 3000 OLS, coherent ZR+ pluggable optics and Mosaic Network Controller, the setup extends previous years’ configurations to include C‑ and L‑band operation and multi‑layer domain control. Adtran’s 800Gbit/s ZR+ pluggables also feature in the OIF plugfest, reinforcing their role in large‑scale, multi-vendor environments.
Adtran today launched LiteWave800™, an ultra‑low‑power 800Gbit/s DR8 linear pluggable optics (LPO) module engineered to help data centers address the power, latency, thermal and bandwidth demands of modern AI and machine-learning (ML) workloads. As GPU clusters grow and short-reach links scale across dense server racks, operators need 800Gbit/s optics that deliver higher capacity within strict power and cooling limits. LiteWave800™ answers this challenge with a fully re-engineered architecture that significantly reduces energy consumption. Operating at just 1pJ/bit and consuming only 0.8W, it establishes a new power class for 800Gbit/s optics, delivering far lower energy per bit than today’s first‑generation LPOs and mainstream DSP-based pluggable transceivers. Adtran will showcase LiteWave800™ at OFC 2026 in Los Angeles from March 17 to 19.
