The Largest Private Companies
The 50 biggest privately held businesses in the Inland Empire, ranked by estimated annual revenue — the companies that drive the regional economy without filing a single public report.
Estimates as of June 2026 · Top 50
The Inland Empire’s private economy runs deeper than its public reputation. A family-owned grocer and a family-owned electronics maker top the list above the billion-dollar mark, but the real story is the breadth beneath them — manufacturers, distributors, contractors, and healthcare groups spread across Chino, Corona, Riverside, and Rancho Cucamonga, most of them growing.
Two patterns stand out. Manufacturing and distribution dominate the roster, a direct reflection of the region’s logistics spine. And private equity has arrived in force: more than a dozen of the fifty are now PE-backed, a sign that outside capital increasingly sees the IE’s middle market as worth buying into.
The Ranking
| # | Company | Revenue (est.) | Ownership | Sector | YoY | HQ |
|---|
Methodology. Companies are ranked by estimated annual revenue. To be eligible, a company must be headquartered or substantially operating in the Inland Empire and must not be publicly traded on a U.S. exchange. Within that definition, all ownership structures qualify — family-owned, founder-led, employee-owned, and private-equity-backed companies are all included. Figures are Citrus Belt Review estimates developed from regional operational knowledge, industry benchmarks, and public sources, rounded to indicate their estimated nature. Ownership reflects controlling structure; where a company is private-equity-backed, the sponsor is noted. Companies may submit verified figures for correction.
