What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 16% now, 23% at the end of 2027, 25% at the end of 2028, 26% at the end of 2030. By the patterns, the work is about 26% desk work, 9% people work and 65% 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 71% of the working time stays with people (conversation, in-person and hands-on work), 23% 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.

The workforce as industry patterns
| Pattern | Share | Reason, from the filing |
|---|---|---|
| Alumina and Aluminum Production and Processing | 85% | Aluminum is 56% of revenue and alumina 44%, from the refineries and smelters the filing names (Portland, Fjarðaál, Bécancour, San Ciprián), which NAICS counts as alumina refining and primary aluminum production (3313), read by description (c) since the filing counts employees by union, not by operation. |
| Nonmetallic Mineral Mining and Quarrying | 15% | The bauxite mines in Australia and Brazil that feed the refineries are read at nonmetallic mineral mining at a small share by description (c), as Freeport's mines and smelters were split; no count by operation is stated. |
What the filing says about the workforce: About 11,400 of 14,900 under collective bargaining agreements (77%): 1,100 U.S., 2,000 Europe, 1,400 Canada, 4,500 South America, 2,400 Australia; women about 22% of the global workforce; agreements at Bécancour and San Ciprián expired and under negotiation.

Questions about this company

- An estimated 16% now and 25% by the end of 2028, on METR's long-run pace at four in five, from the workforce Alcoa Corporation's own annual report describes and BLS staffing patterns for its industries, never from a roster. It is an estimate with a stated method. It is not a forecast of jobs lost or of savings, and it says nothing about what the company will do.

- 14,900 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states.

- Read from its annual report as a blend of 2 industry staffing patterns, the largest Alumina and Aluminum Production and Processing; by those patterns the work is about 26% desk work, 9% people work and 65% body work.

- What does Alcoa Corporation's annual report say about AI?
- 1 sentence in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 0, 0, 0, 1 and 1 sentences, year by year. They are counted and quoted on this page, never judged: a count says how much a filing talks about AI, not what the company does with it.
- How is this estimated?
- Claude Fable 5.1 read the annual report under the Index's written rubric (version 1) on October 19, 2026: the stated headcount, the share in the U.S. when stated, and the workforce as a blend of industry staffing patterns. The estimates are the site's industry estimates weighted by those shares, from O*NET tasks with estimated lengths and METR's measurements of how long a task AI models can finish. A company can write to info@stratussc.com to have its reading checked against its filing.
