From 13F filings, which cover institutions managing over $100m and are filed up to 45 days after the quarter ends — so this is a considered position, not a live one, and it is not the whole shareholder register.
What the company actually paid out and bought back, as reported — the record behind any yield figure.
Ownership percentages are a vendor aggregate, not a filing — unlike everything else on this page.
QUANTA SERVICES, INC. files under SIC 1731 — all 3 electrical work companies compared on assets and F-score.
The structure map above is the Corporate Blueprint, and in the desktop it is interactive — click any entity to re-centre the map on it and walk the ownership chain. It sits alongside the screener, the scorecard and the filings lab on one desk, on your machine.
Sourced from SEC EDGAR primary filings. Figures are as reported by the company and are not investment advice. Scores are standard published screens computed from those filings; every input is shown above so you can check the arithmetic.
