A forward-looking 90-day calendar of every SAM.gov registration expiring in California during Q2 2026, with concentration analysis flagging coordinated-renewal addresses.
California is the largest federal contractor market in the United States by SAM.gov entity count. The Q2 2026 edition covers 16,087 federal contractor SAM registration expirations between April 1 and June 30, 2026 — spanning defense aerospace primes in Los Angeles County, technology and federal services contractors in the Bay Area, and shipbuilding and naval-contracting clusters in San Diego, this quarter's leading expiration city.
Of those expirations, 46 addresses are flagged for coordinated renewals — locations where 3 or more co-located federal contractors share a single SAM.gov expiration date. California's volume of coordinated-renewal addresses is the highest of any state this quarter, reflecting both the absolute scale of the contractor base and the prevalence of shared registered-agent management within California's larger contractor clusters.

California's Q2 2026 edition flags 46 coordinated-renewal addresses. The full Concentration Findings section in the PDF identifies each address, the entities sharing it, and the renewal date.
