Slide 3 — A Message From

3 Dear Stakeholders, We proudly celebrated Universal Display Corporation’s 30th anniversary in 2024. UDC began as a bold vision by our late founder Sherwin I. Seligsohn to revolutionize the display and lighting markets. Built on decades of persistence, innovation, and strong partnerships, we have grown into a global leader in the OLED ecosystem. It took 17 years of determination to reach profitability, but our commitment to pushing the boundaries of technology never wavered. Throughout these 30 years, we’ve delivered trailblazing advancements, adapted to an ever-changing landscape, and stayed true to the spirit of vision and exploration that defined our founding. The journey to today was fueled by our relentless drive and refined through trials and challenges to shape more than success; it laid the foundation for the corporate culture we live and breathe today — one built on curiosity, creativity and collaboration. UDC’s culture empowers our teams to solve complex problems, reimagine what's possible, and deliver with purpose. Just as importantly, we are grounded in our responsibility to do what’s right — for our employees, our communities and the world. From continuously advancing our energy efficiency roadmap, to supporting global STEM initiatives and giving back to our local communities, we remain focused on creating positive, lasting impact. UDC champions and supports a broad spectrum of educational initiatives designed to foster a mindset of discovery and nurture the next wave of innovators in Science, Technology, Engineering, and Math. In 2024, we established the Sherwin I. Seligsohn Innovation Award in organic electronics to honor our founder’s visionary leadership, exceptional intellect and fervent curiosity. Additionally, we’re pleased to announce a new, four-year commitment to Paul Robeson Charter School’s “Building Bright Futures Campaign” to support the construction of two new science labs at its newly designed Trenton, NJ school. We also renewed local academic and research partnerships, including Ewing High School, the Smith Family Foundation, Rutgers University’s Global Entrepreneurship Experience Teen Camp and IMID (International Meeting on Information Display) through scholarships, grants and awards. From inspiring the next generation of scientists and engineers to groundbreaking inventions in our labs, innovation is embedded in our core R&D philosophy. Since 1998, our team of world-class scientists, engineers, and technicians has been driving continuous breakthroughs across critical performance metrics — boosting efficiency, extending lifetime, enhancing color points, and more. Over the years, we've achieved an impressive 8-fold improvement in external quantum efficiency (EQE), significantly advancing OLED energy efficiency and overall device performance. At the same time, we've delivered an extraordinary more than 60,000-fold increase in material operating lifetime, setting new industry benchmarks. Our expanding portfolio of OLED technologies and UniversalPHOLED® materials empowers customers to realize greater power savings, extend battery life, reduce device size, and support next-generation features like 5G and AI — all while lowering power consumption across a range of consumer OLED products. At UDC, our commitment to shaping a brighter, more sustainable future is stronger than ever. As a pioneer in the OLED ecosystem, we continue to invest in our people, infrastructure, and innovation — reinforcing the foundation for long-term growth and our strong leadership position. As the OLED market continues to grow and expand, we remain focused on making a positive difference — not only through the energy-efficient products we invent and deliver, but through supporting and engaging our communities. Together, we’re illuminating the path to a more responsible, inclusive and innovative world. Steven V. Abramson President & CEO A Message From Our CEO

Slide 23 — Engaging Our Workforce

23 Engaging Our Workforce Communication is Critical At UDC, we believe communication is critical. We encourage cross-company communication and knowledge sharing. Our open- door policy provides employees a channel for questions, concerns and suggestions. Every week, our CEO engages in open dialogue with gathered employees at a Company-hosted lunch at UDC’s Ewing, NJ HQ campus to provide Company and industry updates and to celebrate employee milestones (e.g., birthdays, work anniversaries, weddings and births). These talks are shared globally via our intranet. Annually, our domestic and international teams unite at HQ for a week of hands-on meetings and corporate activities. We advocate a company culture of open and honest communication at all levels of the organization. As UDC continues to grow, we invest heavily to train, develop and expand our team. We listen, too, so that we can improve and continue to build and sustain a productive, diverse and thriving workforce. Employee Engagement We conduct Employee Engagement Surveys to guide our continuous improvement efforts and to reaffirm our commitment to listening to our employees. These surveys reflect the value we place on open dialogue and employee input in shaping the future of our business. UDC conducted its most recent survey in October 2023, using an expert third-party provider to ensure employee confidentiality, as well as an opportunity to benchmark our performance against a global database. Key insights include: • 76% of UDC domestic and international employees participated • Scored a 9 for overall employee engagement and employee satisfaction, on a scale of 0 – 10 (highest), ranking in the top 5% of companies for Diversity and Meaningful Work • Areas of strength included Organizational Fit, Reward, and the Process for Rewards UDC is currently in the planning process for its next Employee Engagement Survey, which is slated for the second half of 2025. Note: UDC’s subsidiary Adesis, Inc. conducts its own employee engagement survey and therefore its employees were not included in the October 2023 survey. Additionally, Adesis organizes specialized communications initiatives such as town hall meetings to meet the specific needs of the Adesis team.

Slide 41 — Climate Change Policy

41 Climate Change Policy Universal Display Corporation acknowledges the potentially harmful impact of climate change, and we are mindful of the ways that our company could contribute to that change. We understand that our employees, suppliers, customers and the communities in which we live and serve may continue to be impacted by the effects of climate change, and we are committed to looking into ways through which we can minimize UDC’s greenhouse gas (GHG) footprint as we produce materials that enable energy-efficient consumer devices. In order to fulfill our commitment, we are devoting internal resources, under the direction of the Environmental & Social Responsibility Committee of UDC’s Board of Directors, to focus our efforts in the following areas: • Quantifying our GHG emissions • Establishing time-bound reduction goals and action plans to minimize, whenever commercially practicable, our GHG emissions • Seeking ways to increase energy and water efficiency in our operations and in our supply chain • Investing in opportunities, where economically feasible, to minimize our carbon footprint, particularly through the use of more energy-efficient equipment and mechanical systems, and our continued development of more energy-efficient products that help reduce the GHG impact of devices during their life cycle. UDC has most recently reviewed its Climate Change policy in April 2025. UDC has undertaken and plans to continue to provide periodic updates on the progress it is making on certain of its efforts described above and to publish these results on our public website at www.oled.com.

Slide 42 — Greenhouse Gas Emissions

42 Greenhouse Gas Emissions UDC records and tracks global data on our Greenhouse Gas (GHG) emissions. This data helps us further establish baselines and allows UDC to minimize the impacts of our growth through thoughtful design that incorporates energy efficiency where practical. This data also provides the Company valuable information to establish time-bound reduction goals and action plans. In 2024, UDC fulfilled our 100% electricity offset initiative for its Ewing, NJ HQ campus and Adesis, Inc. (New Castle) facilities, the two locations with the highest electrical consumption, offsetting 74% of our Company Scope 2 emissions. UDC’s 2024 Net Scope 1 and 2 emissions were also 61% lower than 2024 total emissions due to these energy offsets. Calculations: Scope 1 and Scope 2 emissions for U.S.-based locations were calculated using guidance and tools from the United States Environmental Protection Agency (EPA), including the EPA Center for Corporate Climate Leadership’s “Simplified Guide to Greenhouse Gas Management for Organizations” and the EPA’s “Simplified GHG Emissions Calculator”. Scope 1 and Scope 2 emissions for international locations were calculated using guidance and tools from the United Nations Framework Convention on Climate Change (UNFCCC) secretariat, including the Greenhouse Gas Emissions Calculator.
