Ultra Clean Holdings, Inc. (UCTT)

Semiconductor equipment subsystems maker, counted by function. Read October 19, 2026 from the annual report for the period ending December 26, 2025, filed February 23, 2026. Ranked 112 of the 155 Technology companies read so far, by the share within reach now.

A semiconductor subsystems maker whose filing counts its 7,411 employees by function with 6,145 in manufacturing and 555 in administration, so machinery leads and the counted administrative staff take management of companies.

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: 19% now, 32% at the end of 2027, 37% at the end of 2028, 39% at the end of 2030. By the patterns, the work is about 39% desk work, 16% people work and 45% 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 61% of the working time stays with people (conversation, in-person and hands-on work), 31% becomes checking a model's work and 5% could be handed over with lighter checks, from the industries' own figures, not the company's roles.

Headcount

Of our total employees, there were 146 in engineering, 57 in technology development, 508 in sales and support, 4,778 in direct manufacturing, 1,367 in indirect manufacturing and 555 in administrative and executive functions.”
