Quanta Services, Inc.
One of the world's largest builders of electric-grid and utility infrastructure, Quanta designs and repairs power lines, substations, renewable-energy projects, and the electrical systems that keep data centers and semiconductor plants running. It traces back to 1997, when veteran John Colson merged four regional electrical contractors—including PAR, where he'd started as a survey stakes carrier—into one national company. The name borrows from physics' "quantum," the smallest unit of energy, nodding to the essential building blocks of modern power.

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.
Net open-market activity over the last 6 months: -160.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
