The largest companies in Pittsburgh: 25 headquarters ranked by revenue

This ranking is for readers who want Pittsburgh's big headquarters in order: job seekers, suppliers going after corporate contracts, investors and B2B sellers planning enterprise accounts. For the whole market of 61,628 business establishments and the state's employer rankings, see companies in Pittsburgh.

The 25 largest companies headquartered in Pittsburgh

Each row is from the company's latest annual report on Form 10-K: the principal executive office on its cover, revenue as reported, and headcount from its human capital section. We checked every company the SEC lists with a Pittsburgh-area business address and kept those whose filing confirms a headquarters in the Pittsburgh, PA metro.

Notes on the figures:

• Banks. PNC and F.N.B. are shown at total revenue: net interest income plus noninterest income. The SEC's structured data tags PNC's gross interest income ($25.31 billion) instead, which would overstate it.
• EQT gives Pittsburgh on its 10-K cover, although the SEC's company record lists Canonsburg.
• Dick's headcount includes 45,400 people who joined with its acquisition of Foot Locker; American Eagle's includes about 35,000 part-time or seasonal associates.
• Matthews' figure is its own workforce at 31 October 2025; it reports separately on Propelis, a brand-solutions business in which it holds a 40% stake.

Where the people actually are

Most of these companies employ only a fraction of their people in Western Pennsylvania, and few say how many. The 10-Ks that break it out:

For local headcount, the state's Top 50 Employers lists are the better source: PNC Bank ranks fifth in Allegheny County, and PPG, Dick's and Federated Hermes (listed under its old name, Federated Investors) all appear in its top 50.

A list built on industry

Metals and materials still anchor the list (aluminum, aerospace castings, tooling, wood treatment, coatings), while software is a small slice by revenue despite the region's reputation for robotics and AI research. Duolingo is the only software company in the top 25.

Who isn't on the list, and why

Nonprofit and private employers don't file 10-Ks at all, so UPMC, Highmark Health, Giant Eagle and Westinghouse Electric, which all rank high on the state's county employer lists, can't appear in a revenue ranking. Fortune's lists also rank by revenue but use their own definitions and timing; use Fortune's site for its ranks and this table for figures you can trace to a filing.

Changes to watch

1. Alcoa announced on 30 June 2026 that it is acquiring AliGroup in a proposed transaction with South32. On its October 2026 earnings call, Alcoa said South32's shareholders had approved the deal and it expected to close in the first half of 2027.
2. Dick's Sporting Goods has absorbed Foot Locker, which added 45,400 employees.
3. Kraft Heinz reorganized into three reportable segments (North America, Europe and Pacific Developed Markets, and Emerging Markets) in the third quarter of 2026, according to an 8-K filed on 7 October 2026.

Acquisitions and reorganizations reset budgets and vendor lists, so they're the best moments to approach a large company with something new.

Selling to Pittsburgh's headquarters

Before you reach out to any of these companies, read four parts of the 10-K: the segments (each usually has its own budget), the properties list (where the plants are), Item 1A risk factors (what worries the board) and Item 1C (how cybersecurity is governed). Then check the state's county employer lists to see which sites are big locally.

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

Monongahela Analytics (monanalytics.example) sells vibration-monitoring sensors and software that predict equipment failures in plants.

• From the 11 industrial manufacturers, it drops Matthews, L.B. Foster and Ampco-Pittsburgh to focus on eight with $61.4 billion in revenue.
• It assumes each runs at least 20 plants worldwide with 300 critical machines, a pool of 48,000 monitored assets.
• At $400 per asset per year, a 2% share of that pool is worth $384,000 a year.
• It starts with reliability and maintenance leaders at the companies' Pennsylvania plants, where a site visit is a short drive, then uses a working pilot to reach corporate operations.

Bebop can find the reliability and plant leaders at each of the eight and draft outreach that references each company's own segments and plants.

Subject: Fewer surprise outages at [plant name]

Hi [first name],

[Company]'s 10-K lists [plant name] among its [segment] facilities. Unplanned downtime on a few critical machines is usually what drives the overtime and expedite costs that show up in segment margins.

We monitor rotating equipment at 15 plants within 50 miles of Pittsburgh and flag failures two to six weeks out. Could we fit sensors to five of your critical assets for a 60-day trial?

[Your name], Monongahela Analytics
