Item 1.01 Conflict Minerals Disclosure and Report.

Rogers Corporation (the “Company” or “Rogers”) has evaluated the products it manufactured or contracted to manufacture in calendar year 2025 and has determined that certain of those products contained “Conflict Minerals,” as such term is defined in Item 1.01 of Form SD promulgated by the U.S. Securities and Exchange Commission (“SEC”), and that said Conflict Minerals were necessary to the functionality or production of said products. The Conflict Minerals necessary to the functionality or production of those products were tin and gold. Based on a reasonable country of origin inquiry, as summarized below, the Company has reason to believe that certain of its materials containing necessary Conflict Minerals came from recycled or scrap sources. With respect to all other materials containing necessary Conflict Minerals, the Company does not have reason to believe that any necessary tin or gold may have originated in the Covered Countries (defined as the Democratic Republic of the Congo or any adjoining country).

The Company’s Conflict Minerals Program

The Company has established a Conflict Minerals Policy (the “Policy”). The Policy, which is posted on the Company’s public website, provides in part:

Rogers expects its suppliers to source materials from socially responsible suppliers and that all of its suppliers will comply with the Dodd-Frank requirements and provide all necessary declarations and supporting information. Suppliers must pass these requirements through to their supply chain if they do not source directly from mines or smelters and determine the source of the Conflict Minerals used in the product Rogers Corporation purchases. We will assess future business with suppliers who are not cooperative with the conflict-free sourcing initiative and not compliant with this Policy.

The Company’s Conflict Minerals compliance effort is supervised by its Director of Environmental Engineering. The Company’s legal and supply chain functions support the environmental organization with these compliance efforts, and external consultants have assisted the Company in the development of the reasonable country of origin inquiry process.

Determination of Products Within the Scope of the SEC’s Conflict Minerals Rule

The Company considered all products that it manufactured for sale in 2025, or which it contracted to be manufactured during 2025, when determining which of its products were potentially within the scope of Rule 13p-1 of the Securities Exchange Act of 1934, as amended. Materials that were used for maintenance or research and development activities were not included in the process described below.

With respect to materials introduced into production for sale for the first time during 2025 or materials provided by new suppliers during 2025, the Company’s environmental compliance team reviewed each new material to determine whether it may contain Conflict Minerals. In addition, the Company’s supply chain team queried all new suppliers regarding the presence of Conflict Minerals in the materials they supplied to the Company. The Company also monitored additions to the Company’s chemical inventory system for certain Chemical Abstract Services (CAS) registry numbers to ensure that materials that might contain Conflict Minerals were flagged for review prior to being used to manufacture products for sale.

With respect to all other materials that were used in the manufacture of Company products in 2025, the supply chain and environmental compliance teams reviewed the Company’s chemical inventory system and, by using the CAS registry number and Safety Data Sheet information, identified materials that potentially could contain Conflict Minerals.

The results of the analysis by the Company’s supply chain and environmental teams were compiled into a list of materials that might contain necessary Conflict Minerals. The list also included the suppliers of those materials, which the supply chain team identified using purchasing data from its enterprise resource planning system.

Reasonable Country of Origin Inquiry

Using the list described above, all direct suppliers providing materials to the Company in 2025 that were used in products manufactured for sale and might contain necessary Conflict Minerals were surveyed. The Company requested that each supplier certify by way of the Responsible Minerals Initiative Conflict Minerals Reporting Template that the materials it sold to the Company either did not contain Conflict Minerals or, if such materials did contain Conflict Minerals, that those Conflict Minerals (i) did not originate in the Covered Countries or (ii) were from recycled or scrap sources. These direct suppliers were also asked to survey their own suppliers to obtain the same information, and to provide information which supported their certification, including smelter or refiner information, as applicable.

During the inquiry process, all surveyed suppliers informed the Company that either the materials they supplied to the Company in 2025 did not contain Conflict Minerals or provided a certification that the materials which contained Conflict Minerals did not originate in the Covered Countries or came from recycled or scrap sources.
