ADTRAN Holdings Inc. (ADTN)

Broadband network equipment. Read November 8, 2026 from the annual report for the period ending December 31, 2025, filed February 26, 2026. Ranked 160 of the 238 Technology companies read so far, by the share within reach now.

A telecommunications equipment maker with 3,338 employees, two thirds abroad, in one communications equipment pattern by description.

The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

What follows from the reading

Share of working time within reach of AI, on the long-run pace at four in five: 39% now, 52% at the end of 2027, 56% at the end of 2028, 57% at the end of 2030. By the patterns, the work is about 57% desk work, 19% people work and 24% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 43% of the working time stays with people (conversation, in-person and hands-on work), 48% becomes checking a model's work and 7% could be handed over with lighter checks, from the industries' own figures, not the company's roles.
