Eagle Materials Inc's Business Segments

Eagle Materials Inc. is a leading supplier of construction products, building materials, and materials used for oil and natural gas extraction. Our construction products are used in residential, industrial, commercial and infrastructure construction and include cement, slag, concrete and aggregates. Our building materials are sold into similar markets and include gypsum wallboard. Our basic materials used for oil and natural gas extraction include frac sand and oil well cement.

The Company was founded in 1963 as a building materials subsidiary of Centex Corporation (“Centex”), and we operated as a public company under the name Centex Construction Products, Inc. from April 1994 to January 30, 2004, at which time Centex completed a tax-free distribution of its shares in EXP to its shareholders.
We sell cement in six regional markets, including northern Nevada and California, the greater Chicago area, the Rocky Mountain region, the Central Plains region and Texas, and we sell slag in the greater Chicago, Illinois area and the greater Midwest area. We have three concrete and aggregates businesses, serve the areas immediately surrounding Austin, Texas, the greater Kansas City area and north of Sacramento, California. Gypsum wallboard is distributed throughout the U.S. with particular emphasis in the geographic markets nearest to our production facilities. We also operate a recycled paperboard business which sells internally to our wallboard business as well as to external customers. Oil well cement and frac sand are sold into shale deposit zones across the United States.

Eagle Materials Inc. is a well-established company that specializes in various segments of the construction materials industry. The company’s offerings can be broadly categorized into four main segments: Cement and Slag, Concrete and Aggregates, Gypsum Wallboard, and Recycled Paperboard. Each of these segments provides essential products and services that support the construction and building industries.

1. Cement and Slag

Eagle Materials Inc.’s Cement division is a cornerstone of its operations, with multiple cement production facilities strategically located across the United States. The facilities are located in:

- Buda, Texas
- LaSalle, Illinois (operating as Illinois Cement Company)
- Laramie, Wyoming (operating as Mountain Cement Company)
- Sugar Creek, Missouri (operating as Central Plains Cement Company)
- Tulsa, Oklahoma (operating as Central Plains Cement Company)
- Fernley, Nevada (operating as Nevada Cement Company)

In addition, the company operates a slag grinding facility in Chicago, Illinois, known as Skyway Cement Company. It’s important to note that the Buda, Texas plant is operated under a joint venture with Texas Lehigh Cement Company LP.

Cement Production: The cement produced from these facilities acts as a basic binding agent in concrete, essential for various construction projects. The company utilizes a dry process technology for production, with approximately 75% of its clinker capacity derived from preheater or preheater/pre-calciner kilns.

Slag Products: The slag produced is derived from steel manufacturers and is ground at their specialized facility. Slag enhances concrete mix designs by improving durability, which in turn can reduce long-term maintenance costs. This makes it a valuable material in creating more resilient concrete structures.

Concrete and Aggregates

Eagle Materials also plays a significant role in the Concrete and Aggregates sector, offering readymix concrete and a range of construction aggregates.

Readymix Concrete: This is a critical product that combines cement, sand, gravel or crushed stone, and water. The mixing occurs at batch plants, and the concrete is then transported to construction sites in specialized mixer trucks. Readymix concrete is widely utilized due to its versatility and cost-effectiveness in various construction applications.

Construction Aggregates: The aggregates business encompasses the mining, extraction, production, and sale of various materials including:
- Crushed stone
- Sand
- Gravel
- Lightweight aggregates (such as expanded clay and shales)

These construction aggregates are fundamental in numerous construction applications, particularly in producing readymix concrete and asphalt mixes used in highway construction and maintenance.

Gypsum Wallboard

Eagle Materials operates five gypsum wallboard manufacturing facilities, though one—located in Bernalillo, New Mexico—was idled in December 2009 due to fluctuating demand. The company plans to reopen this facility when market conditions are favorable.

Manufacturing Process of Gypsum Wallboard:
1. Mining: Gypsum is extracted from the ground or sourced as synthetic gypsum from power generation companies.
2. Calcination: The extracted gypsum undergoes calcination to convert it into plaster.
3. Slurry Production: The plaster is mixed with additional materials and water to create a slurry, which is extruded between two sheets of recycled paperboard on high-speed production lines.
4. Final Processing: The gypsum wallboard is then cut to size, dried, and bundled for distribution.

Gypsum wallboard is extensively used for finishing interior walls and ceilings in various building types, including residential, commercial, and industrial.

Recycled Paperboard

The Recycled Paperboard segment of Eagle Materials is represented by the Republic Paperboard Company, located in Lawton, Oklahoma. This operation features an advanced paper machine primarily focused on producing gypsum liner products, which are essential for the wallboard production process.

Capabilities:
- The manufacturing facility produces recycled industrial paperboard grades, which are designed for efficiency and performance in high-speed wallboard manufacturing.
- In addition to gypsum liners, the facility can produce containerboard grades and lightweight packaging materials, allowing for versatility in product offerings.

Conclusion

Eagle Materials Inc. is a diversified company in the construction materials space, offering critical products and services across cement, concrete, aggregates, gypsum wallboard, and recycled paperboard. Each of these segments plays a vital role in the construction industry, contributing to various projects and infrastructure developments. The company continues to adapt and evolve its offerings to meet the changing demands of the market while maintaining high standards of quality and efficiency.
