Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Overview of Owens Corning Products

Owens Corning (the “Company”) has three reportable segments: Composites, Insulation and Roofing. The Company’s three reportable segments are defined as follows:

Composites – The Company manufactures, fabricates and sells glass reinforcements in the form of fiber. Glass reinforcement materials are also used downstream by the Composites segment to manufacture and sell glass fiber products in the form of fabrics, non-wovens and other specialized products.

Insulation – Within the Insulation segment, the Company manufactures and sells fiberglass insulation into residential, commercial, industrial and other markets for both thermal and acoustical applications. It also manufactures and sells glass fiber pipe insulation, flexible duct media, bonded and granulated mineral wool insulation, cellular glass insulation and foam insulation used in above- and below-grade construction applications.

Roofing – Within the Roofing segment, the Company manufactures and sells residential roofing shingles, oxidized asphalt materials, roofing components used in residential and commercial construction and specialty applications, and synthetic packaging materials.

Conflict Minerals Disclosure

Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act defines conflict minerals as columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives, which are currently limited to tantalum, tin and tungsten (collectively, “Conflict Minerals”). The Company has conducted an internal review of its products and manufacturing processes and determined that Conflict Minerals are necessary to the functionality or production of the spinners that are part of the machinery used to make some of the Company’s insulation products.

In 2020, the Company contracted to manufacture spinners. Most of the spinners were used at the Company’s facilities in the production of its insulation products and some of the spinners were sold to third parties. The Company conducted in good faith a reasonable country of origin inquiry (“RCOI”) regarding the origin of the Conflict Minerals in the spinners sold to third parties. In conducting the RCOI, the Company contacted each of the two (2) contract manufacturers of spinners containing Conflict Minerals (collectively, the “Suppliers”) and discussed their policies and practices regarding the sourcing of Conflict Minerals. Each of the Suppliers indicated that, either (i) it has received written certifications from its sub-suppliers that the Conflict Minerals they provide to the Supplier do not originate from the Democratic Republic of Congo (“DRC”) or an adjoining country, or (ii) it purchases Conflict Minerals via scrap purchases on the secondary market in accordance with an established conflict-free policy, but in either event the Supplier does not have third-party validation from a particular organization, program or protocol regarding each of the smelters used by its sub-suppliers. The Company has obtained a completed Conflict Minerals Reporting Template from each of the Suppliers that provided no indication or reason to believe that Conflict Minerals in the spinner parts it supplied had originated from the DRC or an adjoining country. The Company plans to continue working with current and future suppliers to ensure that the Conflict Minerals supplied for spinner products do not originate in the DRC or an adjoining country.
