ADTRAN reported stronger-than-expected fourth-quarter results, driven by a surge in demand across its cloud, fiber and AI product lines. The company narrowed its net loss compared with the prior-year period and outperformed consensus earnings estimates.

Robust orders for cloud networking equipment, expanded fiber deployments and increased AI-related infrastructure projects contributed to the quarter’s revenue growth. Management highlighted that enterprise and service-provider spending accelerated late in the quarter.

The company provided a first-quarter sales forecast of $275 million to $295 million, citing potential macroeconomic headwinds. Management emphasized continued strength in its core end markets while remaining cautious on broader economic conditions.
