EASTMAN CHEMICAL CO

The Company's products and operations are managed and reported in four operating segments: Advanced Materials ("AM"), Additives & Functional Products ("AFP"), Chemical Intermediates ("CI"), and Fibers. This organizational structure is based on the management of the strategies, operating models, and sales channels that the various businesses employ and supports the Company's continued transformation towards a global specialty materials company.

In 2023, the Company moved the functional amines product line from the CI segment into the AFP segment. In addition, certain organic acid products and olefin-based products moved from the AFP segment to the CI segment. These product moves are expected to increase efficiency of the Company's assets and commercial teams, and to increase portfolio transparency.
