The largest companies in St. Louis: 22 public headquarters ranked, plus Edward Jones and Graybar

This ranking is for job seekers, suppliers chasing corporate contracts, investors and B2B sellers who want St. Louis's big headquarters in order. For the whole market of 69,470 business establishments and the region's employers, see companies in St. Louis.

The 22 largest public companies in St. Louis

Each row is from the company's latest annual report on Form 10-K: the headquarters on its cover, revenue as reported and headcount from its human capital section. We checked every company the SEC lists with a St. Louis-area address, plus companies whose filings name a St. Louis-area headquarters even though the SEC lists them elsewhere.

Notes on the figures:

• Bunge's 10-K cover gives Geneva, Switzerland as its registered office and principal executive offices and names 1391 Timberlake Manor Parkway, Chesterfield, as its corporate headquarters. We count it here on the strength of that second address; a ranking that uses principal executive office alone would leave it out.
• Stifel and Enterprise Financial are shown at net revenue: Stifel's after interest expense ($6.35 billion before), and Enterprise Financial's as net interest income plus noninterest income.
• Fiscal years differ. Emerson, Post, Energizer, Spire, BellRing and ESCO close their years in September; their next 10-Ks, for years that ended in September 2026, are due later this year.
• Headcounts are company-wide. Advantage Solutions says many of its 73,000 teammates are paid near the minimum wage, so its headcount is high relative to its revenue.

Two big filers with no listed shares

Edward Jones would rank fifth on the list above and Graybar sixth. Most large private companies don't file anything: Greater St. Louis, Inc. names Enterprise Mobility among the region's leading companies, but there's no filing to rank it by.

What the list is made of

Strip out the top four and the list is a mid-sized industrial and consumer-goods economy: 18 of the 22 companies report less than $10 billion. That matters for sellers, because companies between $0.5 billion and $10 billion in revenue usually have one central procurement team, a small number of decision-makers and a clear fiscal calendar.

Who isn't on the list, and why

Greater St. Louis, Inc. counts seven Fortune 500 headquarters and 15 Fortune 1000 headquarters in the region. Fortune ranks by revenue with its own definitions and timing, so use its site for ranks and this table for figures you can trace to a filing.

Changes to watch

1. Olin agreed on 15 June 2026 to a merger of equals with Huntsman, according to Olin's August 2026 filing; the registration statement for the deal became effective on 13 July 2026.
2. Perimeter Solutions acquired MMT in January 2026, adding 356 full-time employees, according to its 10-K.
3. Bunge completed its acquisition of Viterra on 2 July 2025, which helped lift net sales from $53.11 billion in 2024 to $70.33 billion.

Selling to St. Louis's public companies

The ten companies between $0.5 billion and $3.6 billion in revenue (Advantage Solutions through Build-A-Bear) are the most reachable on this list: big enough to buy at scale, small enough that a regional supplier can get a meeting.

Illustrative example. The seller and its figures are fictional; the company figures are from the table.

Arch City Risk Advisors (archcityrisk.example), an insurance broker, places directors and officers, property and cyber coverage for mid-sized public companies.

• It targets the ten companies with $0.5 billion to $3.6 billion in revenue.
• It assumes a typical insurance program of $1.5 million in annual premium and a 10% commission: $150,000 a year per client.
• Winning one program a year pays for a dedicated account team; two is a strong year.
• It times outreach to each company's fiscal calendar, because renewals and budgets often follow the fiscal year end shown in the table.

Its first call is to the treasurer or risk manager, with notes from the company's Item 1A risk factors. Matching each company's renewal date and risk profile is the slow part; Bebop can find the treasury and risk leaders at each of the ten and draft outreach that references their own filings.

Subject: [Company]'s insurance renewal and the risks in your 10-K

Hi [first name],

[Company]'s 10-K lists [cyber incidents / product recalls / supply disruption] among its risk factors. When we compare a company's stated risks with its insurance program, we usually find one gap worth discussing before renewal.

We place coverage for mid-sized public companies in St. Louis and across the Midwest. Would a one-page comparison of your disclosed risks and typical program structure be useful ahead of your [month] renewal?
