Our vibrant Phoenix metropolitan area is a hub of innovation and enterprise, and a recent report shines a light on the private companies making the biggest waves. This year, there's a new titan at the top, showcasing the diverse and robust economic landscape that makes our region so special.

Climbing to the prestigious number one position on the 2026 list of Phoenix Area's Largest Private Companies is TriWest Healthcare Alliance. This vital organization, dedicated to providing healthcare services for military members, their families, and veterans, jumped from its previous second-place ranking, reflecting its significant growth and impact.

Following closely behind are Shamrock Foods Company, delivering $6.2 billion in delicious products, and Sundt Construction Inc., building a strong future with $3.8 billion.

These companies not only contribute substantially to our economy but also provide numerous employment opportunities right here in Maricopa and Pinal counties. Their success underscores the strength and resilience of Arizona's private sector, proving that our community is home to some truly remarkable enterprises.
