A maker of testing, inspection, certification, and software services, UL Solutions helps companies prove their products are safe. Its familiar "UL Mark" appears on everything from toasters and power tools to fire extinguishers, signaling to retailers and regulators that a product has been independently checked. The company grew out of Underwriters Laboratories, founded in 1894 by electrical engineer William Henry Merrill after his work at the Chicago World's Fair. The name comes from the insurance "underwriters" who financed early fire-safety testing—and the story goes that Merrill's team even tested the wires at that 1893 fair.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
