Mastec, Inc.
One of North America's largest infrastructure contractors, MasTec builds and maintains the physical networks behind everyday life—telecom and cable lines, power grids, pipelines, and clean-energy projects for utilities and energy firms. It was born in 1994 from a merger of Church & Tower, a firm led by Cuban immigrant Jorge Mas Canosa, and phone-cable builder Burnup & Sims. Its name blends the Mas family surname with "technology," a nod to its founders.

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 all recorded history: -4.87M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
