The Company has disclosed for each reportable segment the significant expense categories that are reviewed by the CODM in the tables below.

The Company's business segments are as follows:

•Engineered Materials

The Company's Engineered Materials segment includes the engineered materials business and certain strategic affiliates. The engineered materials business develops, produces and supplies a broad portfolio of high performance specialty polymers for automotive and medical applications, as well as industrial products and consumer electronics. Together with its strategic affiliates, the Company's engineered materials business participates in the global specialty polymers industry. The primary products of Engineered Materials are used in a broad range of end-use products including fuel system components, automotive safety systems, medical applications, consumer electronics, appliances, industrial products, battery separators, filtration equipment, coatings, and electrical applications and products.

•Acetyl Chain

The Company's Acetyl Chain segment includes the integrated chain of acetic acid, vinyl acetate monomer ("VAM"), acetic anhydride, acetate esters, emulsion polymers, ethylene vinyl acetate ("EVA") polymers, redispersible powders ("RDP"), and acetate tow businesses. The Company's acetyl chain business produces and supplies acetyl products, including acetic acid, VAM, acetic anhydride and acetate esters. These products are generally used as starting materials for colorants, paints, adhesives, coatings and pharmaceuticals. It also produces organic solvents and intermediates for pharmaceutical, agricultural and chemical products. The Company's emulsion polymers business is a leading global producer of vinyl acetate-based emulsions and develops products and application technologies to improve performance, create value and drive innovation in applications such as paints and coatings, adhesives, construction, glass fiber, textiles and paper. The Company's EVA polymers business is a leading North American manufacturer of a full range of specialty EVA resins and compounds, as well as select grades of low-density polyethylene. The Company's EVA polymers products are used in many applications, including flexible packaging films, lamination film products, hot melt adhesives, automotive parts and carpeting. The Company's RDP business is a leading global producer of redispersible polymer powders. The Company's RDP products are used in a variety of applications in the mortar industry, including decorative mortar, exterior insulation and finish systems, gypsum-based materials, plaster and render, self-leveling floor systems, skim coat and tile adhesives. The Company's acetate tow business is a leading global producer and supplier of acetate tow and acetate flake, primarily used in filter products applications.

•Other Activities

Other Activities primarily consists of corporate center costs, including administrative activities such as finance, taxes, information technology and human resource functions, interest income and expense associated with financing activities and results of the Company's captive insurance companies. Other Activities also includes the components of net periodic benefit cost (interest cost, expected return on assets and net actuarial gains and losses) for the Company's defined benefit pension plans and other postretirement plans not allocated to the Company's business segments.

The business segment management reporting and controlling systems are based on the same accounting policies as those described in the summary of significant accounting policies (Note 2).

Sales transactions between business segments are generally recorded at cost plus a mark-up.

(1)Includes intersegment sales of $78 million, $90 million and $93 million for the years ended December 31, 2025, 2024 and 2023, respectively.

(2)Includes Foreign exchange gain (loss), net.

(3)Includes a decrease in accrued capital expenditures of $17 million, a decrease in accrued capital expenditures of $21 million and a decrease in accrued capital expenditures of $26 million for the years ended December 31, 2025, 2024 and 2023, respectively.

Geographical Area Information

Net sales to external customers based on geographic location are as follows:

Property, plant and equipment, net based on the geographic location of the Company's facilities is as follows:

22. Revenue Recognition

The Company has certain contracts that represent take-or-pay revenue arrangements in which the Company's performance obligations extend over multiple years.

Remaining performance obligations related to take-or-pay contracts are expected to be recognized as follows:

Contract Balances

Contract liabilities primarily relate to advances or deposits received from the Company's customers before revenue is recognized. These amounts are recorded as deferred revenue and are included in current and noncurrent Other liabilities in the consolidated balance sheets.

The Company doesnot have any material contract assets as of December 31, 2025.

Disaggregated Revenue

In general, the Company's business segmentation is aligned according to the nature and economic characteristics of its products and customer relationships and provides meaningful disaggregation of each business segment's results of operations.

The Company manages its Engineered Materials business segment through its project management pipeline, which is comprised of a broad range of projects that are solutions-based and are tailored to each customer's unique needs. Projects are identified and selected based on success rate and may involve a number of different polymers per project for use in multiple end-use applications. Therefore, the Company is agnostic toward products and end-use markets for the Engineered Materials business segment.

The Company manages its Acetyl Chain business segment by leveraging its ability to sell chemicals externally to end-use markets or downstream to its acetate tow, intermediate chemistry, emulsion polymers, redispersible powders and ethylene vinyl acetate polymers businesses. Decisions to sell externally and geographically or downstream and along the Acetyl Chain are based on market demand, trade flows and maximizing the value of its chemicals. Therefore, the Company's strategic focus is on executing within this integrated chain model and less on driving product-specific revenue.

Further disaggregation of Net sales by business segment and geographic destination is as follows:

(1)Excludes intersegment sales of $78 million, $90 million and $93 million for the years ended December 31, 2025, 2024 and 2023, respectively.
