A Message from our Chair

Dear Fellow Stockholders,

As Chair of the Board, I am pleased to reflect on 2025 as a year of strong performance and continued progress for UL Solutions — one that reinforced both the strength of our business and the enduring relevance of our mission of working for a safer world.

In our second year as a public company, UL Solutions continued to mature — strengthening governance, deepening accountability and investing with discipline for long-term growth. The Board was encouraged by the company’s resilience and focus in a dynamic global environment, and by the continued trust UL Solutions earns from customers, regulators and communities worldwide.

My connection to the UL enterprise spans many years, beginning during my tenure as president and CEO of the National Fire Protection Association. Through close collaboration with Underwriters Laboratories, and later with UL Solutions, UL Research Institutes and UL Standards and Engagement, I saw firsthand how a steadfast commitment to safety science and integrity drives meaningful and lasting impact. That commitment remains as strong today as ever.

In 2025, UL Solutions enhanced its ability to address emerging safety challenges through targeted investments in expertise, infrastructure and capabilities across key growth areas, such as electrification, connected technologies, the built environment and fire safety — an area once and always central to our legacy. These actions reflect a long-term perspective focused on preparedness, relevance and impact.

The UL Mark remains a globally recognized symbol of trust and responsibility, upheld every day by employees whose dedication to scientific excellence, independence and integrity brings our mission to life.

I am proud of the progress UL Solutions made in 2025 and confident in the company’s trajectory. As described in our President and CEO’s letter, the year’s accomplishments reflect the strength of our strategy and leadership team. With a clear purpose, strong governance and a legacy built on trust, I believe UL Solutions is well-positioned to deliver sustainable value — measured not only in results, but also in the impact we make.

Sincerely, James M. Shannon Chair of the Board of Directors

A Message from our CEO

Dear UL Solutions Stockholders,

I’m exceptionally pleased to report that 2025 was an outstanding year for UL Solutions. In our second year as a public company, we delivered record financial performance while navigating a complex global environment. Our results reflected the durability of our business model, the essential nature of our services and the strength of our global team.

We surpassed $3 billion in annual revenue for the first time and maintained our investment-grade balance sheet. At the same time, we continued to invest for long-term growth — opening and expanding laboratories, advancing safety science and standards and deepening capabilities across high-growth sectors such as data centers, energy storage, connected technologies, fire safety and digital services.

UL Solutions is truly more relevant than ever, more than 130 years after our organization was founded during the dawn of electricity.

I often say, “Innovation without safety is failure.” Today’s rapid innovation and evolving megatrends dominating the headlines — including the energy transition, sustainability and connected technologies — make our mission of working for a safer world increasingly critical.

Our work is meaningful, backed by science and in demand from customers who trust us to help them solve problems and bring products to market quickly, safely, sustainably and securely. Indeed, as our more than 80,000 customers continue to innovate, we support them by meeting them where they are, advancing our own capabilities and investing where it matters most: in our people, our laboratories and our technology.

Key accomplishments in 2025 included:

Now in our third year as a public company, I believe we are exceptionally well-positioned for continued success. With a strong financial foundation, global reach and our unwavering commitment to working for a safer world, we remain focused on delivering long-term value creation for our customers, our people and our stockholders.

I look forward to sharing more at our Annual Meeting of Stockholders on May 20, 2026 at 8:00 a.m. Central Time, which will be held through a virtual web conference at www.virtualshareholdermeeting.com/ULS2026.

Sincerely, Jennifer F. Scanlon President and Chief Executive Officer
