Public Company Guide

What is the Greater Phoenix Public Company Guide?

It is a free, public reference tool from the Greater Phoenix Economic Council (GPEC) that maps and lists the publicly traded companies whose corporate headquarters sits in the Phoenix-Mesa-Chandler metropolitan area. It combines an interactive map, a sortable table, and a detail panel for each company covering its ticker, exchange, sector, market capitalization, employee count, index memberships, and trailing one-year share price. It requires no login, subscription, or expertise.

Does the guide list every public company headquartered in Greater Phoenix?

No, and that is deliberate. The guide is a vetted roster of companies that are genuinely operating and currently traded, not a list of everything that files with the SEC from an Arizona address. Blank-check shells and other non-operating filers are excluded on the SEC’s own industry classification, so a shell that completes a merger and becomes a real business is admitted automatically. Bonds, preferred shares, warrants, and secondary share classes are consolidated under the operating company, which appears once. Issuers that report to the SEC but have no public trading market are out of scope, as are over-the-counter companies without current SEC filings and at least $1 million in annual revenue. A company whose listing has ended is removed. Where a call is genuinely close the company is kept and the disagreement recorded, since a wrongly included company is visible and correctable while a wrongly excluded one is not.

What counts as a Greater Phoenix public company in this guide?

Greater Phoenix means the Phoenix-Mesa-Chandler, AZ Metropolitan Statistical Area, which is Maricopa and Pinal counties. A company qualifies if its corporate headquarters is inside that area and its common stock trades on a major U.S. exchange, on a senior foreign exchange, or over the counter with current SEC reporting and at least $1 million in annual revenue. Because published addresses sometimes disagree, the location test is decided by corroboration rather than by any single source: the company’s own filing cover page, the address it reports to the SEC, an independent public reference record, and its commercial profile each cast a vote, and the majority of the sources holding an address decides. Companies with only a regional office, distribution centre, or satellite site here are intentionally excluded.

Why does the list include companies listed in Canada or over the counter?

Because the test is where a company is headquartered, not where its stock happens to trade. A few Greater Phoenix companies have their primary listing on a Canadian exchange and appear as TSX, TSX Venture, or CSE — the Toronto Stock Exchange, TSX Venture Exchange, and Canadian Securities Exchange. Those venues impose continuous-disclosure obligations comparable to a U.S. listing, so the listing itself is sufficient evidence. U.S. listings appear as NYSE or Nasdaq, which between them cover NYSE American and every Nasdaq tier. An over-the-counter quotation carries no disclosure obligation of its own, so companies shown as OTC have to demonstrate they are operating another way — current SEC reports and at least $1 million in annual revenue.

Why is a particular company missing from the list?

Usually because most sources place its global headquarters outside Maricopa and Pinal counties, even where it has a large local presence or a divisional headquarters here. The other common reasons are that the company is privately held, that the security in question is consolidated under the issuer’s primary listing, that it is a non-operating filer, or that it was recently acquired, taken private, or delisted; the vetting question above covers each of those. If you think something may have been left out, email research@gpec.org.

Are companies with a large local presence but no headquarters here included?

No, and that is a deliberate limitation worth stating plainly. Many more public companies operate significant campuses, fabs, distribution centres, and regional headquarters across Greater Phoenix than appear in this guide. The roster answers one narrower question: where is the corporate headquarters, and therefore the executive decision-making, located.

How often is the data updated, and is any of it maintained by hand?

The dataset refreshes automatically once a day, unattended, so prices, market capitalizations, and index memberships reflect the most recently completed trading session. The table caption inside the guide shows the date of the latest refresh. The roster is rebuilt from its sources on every run rather than edited, so there is no hand-maintained list of companies: arrivals, relocations, and departures appear on their own. Because a company’s SEC address is refreshed with every filing it makes, most relocations show up within a quarter, and membership is re-checked on every run against the SEC’s own ticker-to-exchange table, so a company that has been acquired or delisted drops out by itself. The one exception is the Fortune placements, which are transcribed by hand after Fortune publishes each annual edition.

How do I report a correction?

Email research@gpec.org with the company name and what may need correcting. Because the guide re-reads its sources every day, an error that originates in a company’s SEC filing or commercial profile will correct itself here once it is fixed upstream, so those are worth raising with the source as well. We can fix anything specific to this guide directly, such as a mismatched logo, a misplaced headquarters marker, or a company that should or should not be on the list.

Are the market capitalization and employee numbers global or regional?

Both are global, company-wide totals rather than estimates of activity inside Greater Phoenix. Market capitalization is the company’s full publicly traded valuation, and the employee count is its total reported worldwide workforce. Those are the figures companies report consistently, and they capture the economic weight of having the headquarters itself located here.

What does it mean when a company is marked as part of the S&P 500 or a Fortune list?

Both are widely watched benchmarks. The S&P 500 tracks 500 of the largest U.S. public companies by market capitalization, and the Fortune 500 and Fortune 1000 rank U.S. companies by annual revenue. Appearing on either places a company among the most economically significant of its peer group. Fortune 500 and Fortune 1000 are trademarks of Fortune Media IP Limited, which is not affiliated with GPEC and does not endorse this guide.

How do I narrow the list down?

The filter bar above the table offers a search box that matches company names and ticker symbols, a sector menu, a headquarters city menu, and chips for Fortune 1000, Fortune 500, and S&P 500 membership. Filters combine, so you can ask for Fortune 500 technology companies in Chandler in one pass. A running “Showing X of N companies” line reports the result count, the map hides the markers that no longer match, and Reset clears everything at once.

How does the table work?

The table shows the company logo, name, market capitalization, worldwide employee count, sector, industry, and headquarters city. Click any column header to sort by it, and click again to reverse the direction; the table opens sorted by market capitalization, largest first, and companies with equal or missing values fall back to alphabetical order, so every sort surfaces the most recognizable names in each group first. On a narrow screen the logo and name stay pinned to the left while the rest scroll sideways, so a company is always identifiable. Clicking a row opens that company’s full profile.

How do I use the map?

On a computer, hovering a logo shows a quick card with the company’s ticker, exchange, sector, industry, and city, and clicking it opens the full profile. On a phone or tablet, tap a logo to open the profile directly. To zoom on a computer, hold Ctrl (or Command on a Mac) while scrolling, or pinch on a trackpad; scrolling without a modifier key scrolls the page instead, and a brief on-map hint says so. On a phone or tablet, a one-finger swipe scrolls the page while two fingers pan and zoom the map, so you can always move past the guide without getting trapped in it. Where the browser supports it, a button in the map’s top-right corner expands the guide to fill the screen, and scrolling zooms directly once there is no page behind the map; that button is hidden rather than shown-and-broken on browsers without full-screen support, which notably includes Safari on iPhone.

Why do some logos sit slightly away from their address?

Headquarters cluster tightly along a few corridors, and at metro-wide zoom several logos would land on top of one another and become unreadable. Overlapping logos are nudged apart just far enough to stay legible, and a small dot marks the company’s true coordinate with a dashed line connecting it back to the logo that moved. The nudge shrinks as you zoom in, so each logo settles onto its exact location at street level.
