I built a visual guide for building boundaries of public corporations as of 2019. Here’s an interactive map of publicly listed firms’ headquarter buildings as of 2019: Buildings from “Corporate Shadow Lobbying” (Nagaraj 2026). You can filter for financial factors (like deciles of sales or market cap), and search for firm names, cities, or states to explore the exact buildings reported in these firms’ 2019 10-K filings.
