About this Report

The Rogers Corporation 2024 Environmental, Social and Governance (ESG) Report covers the reporting period of January 1, 2023 to December 31, 2023, except where noted. This report and Rogers' previous ESG reports can be found on our website.

In this report, you will find the following:

• Explanations of Rogers' participation in markets that reduce CO2 emissions;
• Our sustainability practices within our manufacturing operations;
• Rogers' targets to reduce greenhouse gas (GHG) emissions;
• The Company's approach to employee safety, development, and recognition; and
• The ways we ensure ethics and integrity in our corporate governance.

This report aligns with established sustainability and reporting frameworks, including those published by the Sustainability Accounting Standards Board (SASB), specifically the Hardware Industry standard for the Technology & Communications Sector (TC-HW), Version 2023-12.

Verification Opinion of Third-

Party Assurance Provider:

Limited assurance was obtained after reviewing greenhouse gas (GHG) data, calculations, methodologies, and management systems. Cameron-Cole conducted a thorough examination of the source data, including electricity and fuel invoices, as well as the processes and procedures involved in compiling the GHG emissions inventory.

Additionally, GHG emissions were recalculated to ensure that the inventory was devoid of material errors. Based on the method employed and the results of our verification activities, Cameron-Cole has found no evidence of material errors, omissions, or misstatements in Rogers's CY2023 GHG Statement. Cameron-Cole also found that Rogers's GHG accounting and calculation methodologies, processes, and systems for this inventory conform to the WRI/WBCSD GHG Protocol.

Cautionary Statement

The data presented in this report is collected using accepted and relevant scientific and industry-recognized methodologies. However, in some instances, these methodologies are based on assumptions and estimates. While our data has undergone internal vetting, it is important to acknowledge inherent uncertainties and limitations in data collection and presentation. Although we believe such information is reasonably accurate and follows generally accepted principles and methodologies, the collection of such data lies outside our direct influence. Historical performance data may be revised due to factors such as new data availability; industry-driven changes

to methodologies; improvements in data collection, or corporate activities like joint ventures, mergers and acquisitions, or divestitures. When historical information is revised, we will provide clear explanations in footnotes. Statements about future developments and past occurrences are based on information and assumptions available as of the date of publication. While we are committed to timely updates, the Company bears no obligation to continually update information or statements.

For nearly two centuries, Rogers' materials have enabled leading-edge technologies that have revolutionized how we live. We are proud that our work results in a cleaner, safer, and more connected world.

Rogers' materials feature prominently in applications aimed at reducing carbon emissions. Our differentiated advanced electronics and elastomeric materials offer electric and hybrid- electric vehicle (EV/HEV) design engineers best- in-class solutions. These products significantly improve the performance of power modules, power transfer, and batteries to make these critical components more efficient, reliable, and safe. In the renewable energy market, such as wind turbines and solar power plants, Rogers' materials enable the connection between

the power source and components, while our ceramic substrates help cool internal parts for more efficient operation. Our products are also used in general industrial applications that help reduce energy usage in factories.

Rogers is at the forefront of Advanced Driver Assistance Systems (ADAS), where our materials improve vehicle safety by detecting and adjusting to environmental conditions. In addition, our materials protect medical shipping containers that transport life-saving vaccines and organs. And we connect the world by enabling wireless telecommunications and preventing damage to portable electronic devices.

Our role doesn't stop at innovating and manufacturing our solutions. From our sales engineers to our technical service resources, we collaborate closely with our customers to understand their unmet needs to provide materials that meet or exceed their performance requirements.

In our operations, we are committed to manufacturing processes that comply with government and agency standards for environmental health and safety. This year, we are taking our commitment to protect the environment a step further by announcing our goal to reduce Scope 1 and Scope 2 GHG emissions at our manufacturing sites by 20% by 2030 with a baseline year of 2022.

Since our founding in 1832, we've reinvented ourselves through decades of change. One thing remains constant - we know that creating long-term value depends not only on building customer loyalty but also on delivering for our shareholders, giving our employees an enriching work environment with opportunities

to grow, and caring for the communities where we operate. Our employees are guided by our Cultural Behaviors, which represent Rogers' values, while our Diversity, Equity, and Inclusion (DEI) program is maturing and expanding. For our investors, we strive to provide an attractive return on investment while holding ourselves to the highest standards regarding corporate governance and financial reporting.

We look forward to introducing further innovations that advance the goal of reducing carbon emissions. As we do so, we will maintain our focus on the employee experience while delivering results for our investor community.

Regards,

Colin Gouveia

President and Chief Executive Officer
