Testing & certification certification testing revenue mix measures certification testing revenue as a percentage of total UL Solutions revenue.
Certification Testing generated $237M, or approximately 29.0% of revenue, in the second quarter of 2026, up from $215M a year earlier.
Certification testing is distinct from ongoing certification services
Certification testing captures the initial testing work associated with product certification, while ongoing certification services are reported separately.
Keeping the categories separate helps distinguish project-like testing from recurring certification activity.
Revenue mix is not test count
The category share can change with pricing, test complexity, customer mix, and growth in other service categories.
Compare it with ongoing certification services revenue mix and non-certification testing revenue mix.
