Is ULS a Buy? What to Consider in 2026
Short answer
The bull case for ULS (ULS) rests on Regulation-driven recurring demand: Products carrying the UL mark require ongoing follow-up testing to stay certified, which creates sticky, repeatable revenue. Revenue (FY2025) is ~$3.05B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: The most cited risk is valuation: at a trailing P/E in the low 50s and a forward multiple well above the mid-teens typical of professional-services peers, the stock prices in continued strong execution and leaves little room for disappointment. Whether ULS is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
UL Solutions Inc. is a global safety-science company that traces its roots to Underwriters Laboratories, founded in 1894. It earns money by testing, inspecting and certifying products against safety and performance standards, most visibly through the UL mark found on consumer electronics, appliances, wiring and industrial equipment. The business runs across three segments: Industrial (energy, automation, engineered materials and the built environment), Consumer (electronics, medical devices, appliances, HVAC and lighting), and Software and Advisory (regulatory, supply-chain and sustainability tools). Much of the revenue is recurring, because certified products need ongoing follow-up testing to keep their marks, and the company remains majority controlled by the nonprofit UL Standards and Engagement following its April 2024 IPO. The investment picture centers on quality versus price. ULS delivers steady mid-single-digit organic growth, expanding margins and reliable free cash flow, benefiting from long-term tailwinds like electrification, connected devices, tighter regulation and supply-chain scrutiny. Since its IPO the stock has roughly tripled, and it now trades at a large premium to testing-and-certification peers such as SGS, Bureau Veritas and Intertek. That premium leaves the shares sensitive to any slowdown in growth, margin progress or the broader industrial and consumer demand that drives testing volumes.
What's the case for buying ULS?
1. Regulation-driven recurring demand
Products carrying the UL mark require ongoing follow-up testing to stay certified, which creates sticky, repeatable revenue. Tightening safety, energy and connectivity standards across markets tends to expand the scope of what must be tested. This gives ULS a structural tailwind that is less tied to any single product cycle.
2. Electrification and new technology testing
Growth areas like EV components, batteries, renewable energy, connected devices and data-center equipment all need safety and performance certification. UL Solutions is positioned in these categories through its Industrial and Consumer segments. Rising complexity in these products generally means more testing work per unit.
3. Software, advisory and acquisitions
The Software and Advisory segment adds higher-margin regulatory, supply-chain and sustainability tools that complement the core lab work. The company has also expanded through acquisitions, including agreeing to buy Eurofins' electrical and electronics testing business for roughly $670 million. These moves broaden the footprint and add cross-selling opportunities.
4. Margin expansion and cash generation
Management has focused on operating leverage, pricing and productivity to lift margins from the levels seen around the IPO. The asset-light, brand-driven model produces steady free cash flow. Continued margin progress is a key part of the bull case at the current valuation.
What are the risks to ULS?
The most cited risk is valuation: at a trailing P/E in the low 50s and a forward multiple well above the mid-teens typical of professional-services peers, the stock prices in continued strong execution and leaves little room for disappointment. Growth is only mid-single-digit organically, so testing volumes are exposed to industrial and consumer demand cycles, and softness in manufacturing or new-product launches could weigh on results. China exposure, tariff and trade shifts, and currency swings add uncertainty, as the company flags in its filings. Acquisition integration (including the Eurofins deal) carries execution risk, and the nonprofit UL Standards and Engagement retains voting control, limiting public shareholders' influence. Any margin stall or slowdown could compress the premium multiple quickly.

How do you decide if ULS is a buy?
Rather than asking whether ULS is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold ULS indirectly through an index or sector ETF before adding more.
