About the company
MCI Communications Services LLC Verizon Division, doing business as MCI, is a wholly owned subsidiary of Verizon Communications Inc. that delivers wired telecommunications services—voice over internet protocol transport, managed network services, commercial voice solutions, and long distance switched voice—to federal defense and civilian agencies as a prime contractor on full-and-open vehicles and GSA schedules, with no use of small business set-asides.
MCI competes exclusively as a large business prime contractor across two dominant parent vehicles. The Networx government-wide acquisition contract carries 11,467 task orders worth $2.14 billion in combined potential value, making it the anchor of MCI's federal footprint; the GSA Multiple Award Schedule holds 5,919 task orders valued at $205.5 million. A Federal Supply Schedule contract awarded May 12, 2025 with a $700,000 ceiling through May 11, 2030 covers IT and cybersecurity professional services and electronic equipment, with labor pricing ranging from $187.61/hour for IT Manager I positions to $473–$531/hour for senior cyber subject matter expert roles. The Information Technology Schedule 70 vehicle carries 5,887 task orders with $10.5 million combined value. Work spans multiple indefinite delivery contracts; the largest (GS00T06NSD0001) holds 2,077 task orders worth $268.5 million.
Customer concentration is extreme and defense-dominated. The Army Cyber Command anchors the portfolio with 8,174 awards valued at $1.24 billion—39% of all awards and 33% of combined potential value. The Defense Information Systems Agency follows with 2,070 awards and $308.1 million. The Department of Defense Education Activity, despite fewer awards, places $155.1 million in potential value, indicating substantial dollar-per-order magnitude. The Defense Contract Audit Agency, Defense Contract Management Agency, and Naval Computer and Telecommunications round out the top five agencies. These five customers represent 62% of recent award count and account for $1.79 billion, or 49% of combined potential value. Activity has declined sharply: 3,618 awards in FY2022, 2,433 in FY2023, 67 in FY2024, 24 in FY2025, and 2 through August 2026. The recompete cliff is negligible—only $910 thousand in awards completing within the next twenty-four months, suggesting minimal near-term competition pressure or contract turnover.
SCI-reported invoiced revenue totaled $3.9 million across FY2023 and FY2024 ($2.1 million and $1.8 million respectively), capturing service contracts above the $150,000 reporting threshold. The 23 SCI records show 0.0 FTE reporting across all fiscal years, indicating that SCI-reportable work either involved no labor delivery or was exclusively goods-based and therefore not FTE-billable. MCI performed as prime on all SCI records with 0% subcontractor hour share, confirming build-to-suit delivery posture on captured work. Recent representative awards illustrate the portfolio: a $484.65 thousand ratification of charges for IT services to the Office of the Inspector General (September 2024), a $108 thousand high-speed data circuit rental for the U.S. Secret Service in Cincinnati through August 2029 (August 2026), a $57.6 thousand Networx delivery order for telecommunications services to the International Boundary and Water Commission U.S.-Mexico in El Paso (January 2024), and multiple sub-$25,000 Networx managed network service and VoIP transport delivery orders to Army Cyber Command (June–October 2024). MCI also subcontracts selectively; it delivered end-user-centric IT support services to Leidos under a contract between September 2024 and August 2025. The vendor operates from Ashburn, Virginia with all work performed domestically on non-set-aside, full-and-open contracts priced firm-fixed.
