About UL Solutions

If you’ve ever looked at the back of an appliance and seen a small, circular "UL" logo, you've seen the mark of a company that has been quietly shaping our world for over a century. UL Solutions is a global leader in applied safety science, the company that tests, inspects, and certifies everything from consumer electronics to new mobility solutions to ensure they are safe, secure, and sustainable. It’s a mission born from one of the most exciting, and dangerous, moments in modern history. The story starts in 1893 at the Chicago World's Fair. The event was a dazzling showcase of electricity, but with it came a massive fire risk. An MIT-trained engineer named William Henry Merrill, Jr. was sent by fire underwriters to investigate. What he discovered was a chaotic landscape of unproven electrical components. Merrill saw the urgent need for a scientific, standardized approach to safety. A year later, in 1894, he founded the Underwriters' Electrical Bureau, the entity that would evolve into UL Solutions. The organization officially incorporated as Underwriters Laboratories in 1901. It introduced its first standard for tin-clad fire doors in 1903 and began its label service in 1906, placing the now-iconic UL Mark on products that passed its rigorous tests. For decades, UL operated as a nonprofit, expanding from fire and electrical safety into new fields like cybersecurity, autonomous vehicles, and sustainable energy. A major turning point came in 2022 when the parent organization restructured, creating UL Solutions as a distinct, for-profit business alongside two nonprofit entities. This set the stage for its Initial Public Offering in April 2024, when UL Solutions began trading on the New York Stock Exchange under the ticker "ULS." Today, UL Solutions continues its mission of "working for a safer world," helping companies navigate complex global supply chains and innovate with confidence, from advancing 5G to enabling a new era of AI-powered products.
