The biggest companies in Dallas: 25 Dallas County headquarters ranked by revenue

This ranking is for readers who want the biggest companies in Dallas in order and on the record: suppliers looking for corporate buyers, job seekers, students and sellers planning enterprise accounts in North Texas. It covers Dallas County, which includes the city of Dallas, Irving and most of Richardson. For the wider metro, with its small businesses and how to check one, see companies based in Dallas.

The 25 biggest companies headquartered in Dallas County

Revenue and company-wide headcount come from each company's latest 10-K, and the city from the principal executive office on its cover page.

n/a: no company-wide total found in the 10-K.

Notes on the table:

• Addresses. Kimberly-Clark's and Southwest's 10-K covers give Dallas post office boxes; the Dallas Regional Chamber places Kimberly-Clark in Irving and Southwest at Love Field, and we follow the Chamber for Kimberly-Clark. Digital Realty's 10-K gives Dallas, though the Chamber notes the company's website names Austin as its headquarters.
• Revenue. CMC's figure is for the year to August 31, 2026, from a 10-K filed on October 16. AECOM's and Jacobs' are for years to September 2025; neither had filed its 2026 report by 30 October 2026. Somnigroup, which owns Tempur Sealy and Mattress Firm, grew revenue 51.6% in 2025, its first year including Mattress Firm, acquired in February 2025.
• Headcounts. CBRE's includes Turner & Townsend; Jacobs' includes about 1,800 contingent workers; about 23% of Tenet's staff are part-time or on call; most of Brinker's 85,003 are hourly restaurant team members.

Atmos Energy ($4.70 billion, year to September 2025), Copart ($4.67 billion, year to July 2026), ATI ($4.59 billion), Matador Resources ($3.70 billion) and Match Group ($3.49 billion) would rank 26 to 30.

Left out, and why

Dallas, Irving and the rest of DFW

The Dallas Regional Chamber's 2026 guide counts 49 Fortune 1000 headquarters in Dallas-Fort Worth and 24 Fortune 500, two more than in 2025. Grouped by where they are:

Irving's 11 reported $570.65 billion of the top 25's revenue, 58.4%, though McKesson alone is most of that. The Census Bureau counts 653 corporate, subsidiary and regional managing offices in Dallas County, employing 89,756 people at an average of $120,908 a year: the headquarters jobs behind the table.

Dallas County also has bigger workplaces than most places: 23.2 employees per establishment across its 71,182 establishments in 2023, with 133 sites employing 1,000 or more and 234 employing 500 to 999.

What the list says about Dallas

The 25 cover a wide spread of industries. Distribution and health care (McKesson, Tenet), telecoms (AT&T), energy and pipelines (Energy Transfer, HF Sinclair, Vistra), industrials (Caterpillar, Celanese, Flowserve, Lennox, Commercial Metals), engineering and construction (AECOM, Fluor, Jacobs, Primoris, Builders FirstSource), real estate (CBRE, Digital Realty) and consumer brands (Kimberly-Clark, Brinker, Somnigroup) all have a seat. For a seller, most enterprise categories have several large buyers in the county.

Selling to Dallas's biggest companies

The 10-Ks point to two different kinds of account:

1. Headquarters-heavy companies such as AT&T, Texas Instruments and McKesson, where Dallas is the decision center for a national or global business. Sell to the corporate function that owns the budget.
2. Frontline-heavy companies such as Tenet, Brinker and CBRE, whose people are mostly in hospitals, restaurants and client buildings across the country. Their buying problems are about reaching and keeping a dispersed, often hourly workforce.

Illustrative example. The company, rates and results are fictional; the workforce figures are from the 10-Ks.

Shiftline (shiftline.example) sells a mobile app for frontline communication and shift swaps, priced per active user per month.

• Brinker: 85,003 team members, most of them hourly.
• Tenet: nearly 100,000 people, about 23% part-time or on call.
• Builders FirstSource: about 28,000 employees across lumber yards and plants.
• Together, about 213,000 frontline-heavy employees at three Dallas County headquarters.
• A pilot in one Brinker region with 10,000 team members, at 30% adoption, is 3,000 active users, or $9,000 a month at $3 per user.

It targets chief operating officers and heads of field HR rather than IT, and offers a 90-day pilot in one region or brand. Mapping who runs operations and frontline HR at each company is the research Bebop does for each account.

Subject: Reaching [Company]'s hourly teams before the shift

Hi [first name],

With [number] people across [locations], most of [Company]'s workforce never opens a corporate inbox, so schedule changes and safety notices travel by text chain.

Our app gives frontline teams shift swaps and one-tap updates, with read rates by location. Could we pilot it in one region for 90 days and compare no-shows with the rest of the business?

[Your name], Shiftline
