About the company
International Support Group LLC, doing business as ISG, is an SBA-certified 8(a) minority-owned small disadvantaged business (Black American-owned) that delivers facility operations, maintenance, janitorial, HVAC systems, and custodial services to the federal government primarily as a prime contractor (96% of recent awards). Headquartered in Miramar, Florida, ISG competes predominantly under 8(a) set-asides — across recent work, roughly 40% of awards carry Competitive 8(a) or 8(a) Sole Source designations, with the remainder awarded full-and-open or as no-set-aside task orders under larger 8(a) IDIQs.
ISG's customer footprint is heavily concentrated in civilian facility operations. The top five funding agencies account for 73% of awards by count: the Department of Agriculture's Agricultural Research Service / Central Program Planning Coordination and Support (62 awards, $14.2 million), the Department of Homeland Security's Customs and Border Protection (31 awards, $17.1 million), the Department of the Navy's Naval Air Systems Command (22 awards, $3.3 million), the Department of Transportation's Federal Aviation Administration Headquarters (17 awards, $21.6 million), and the Department of the Army's Corps of Engineers (15 awards, $10 million combined potential value). However, by dollar value, the ranking shifts: the Army Reserve Command anchors the portfolio with 6 awards valued at $48.6 million combined, followed by FAA ($21.6 million), CBP ($17.1 million), USDA ($14.2 million), and Army Installation Management Command Southeast Region ($12.6 million). This split reflects ISG's positioning: volume work centers on small, recurring USDA, Navy, and FAA facility maintenance task orders; large multiyear contracts with the Army Reserve Command and CBP drive the dollar total.
Representative work includes a $12.4 million Competitive 8(a) definitive contract awarded by Department of Defense Southeast Region on October 1, 2024, for base-wide custodial services at Fort Rucker, Alabama through September 30, 2029; a $3.7 million 8(a) Sole Source definitive contract from Department of Labor's Atlanta Job Corps Center for interim security and caretaker services at the new Atlanta Job Corps Campus; a $3.5 million Competitive 8(a) definitive contract from Army Corps of Engineers for W. Kerr Scott Project operations and maintenance in North Carolina through October 31, 2029; a $1.74 million Competitive 8(a) contract from FAA for janitorial and landscaping services at Northern California TRACON through August 31, 2026; and a $1.3 million 8(a) Sole Source contract from Department of Labor for facility caretaker services at Gainesville Job Corps Center. ISG also holds four large indefinite delivery vehicles: a $20.5 million Total Small Business IDC with Army Reserve Command (Region 1 facility investment services, another $20.5 million with Army Reserve Region 3, with recent delivery orders valued at $2.2 million and $1.3 million), a $5.6 million Competitive 8(a) IDC with Naval Air Systems Command for HVAC systems services at Jacksonville Fleet Readiness Center Southeast, a $3.24 million Competitive 8(a) single-award IDC with USDA for National Agricultural Library facility operations and maintenance through May 31, 2029, and a $100 million GSA Federal Supply Schedule contract effective through April 30, 2029, spanning 65 labor categories at rates from $16.68 to $92.78 per hour covering janitorial, maintenance, HVAC, plumbing, facilities support, and project management roles (no security-cleared positions).
Activity has been volatile. Award volume peaked at 47 in 2024, fell to 23 in 2025, and dropped to 3 in 2026 (through May)—a trajectory signal that tracking for recompete cliff significance: 14 awards valued at $20.5 million combined face ultimate completion within the next twenty-four months and require recompete action. Recent NAICS concentration confirms ISG's identity: 98 awards in Facilities Support Services (561210), 37 in Janitorial Services (561720), 28 in HVAC Contractors (238220), and smaller slices in commercial building construction and security systems. PSC coding aligns: 56 awards in Operation of Other Administrative Facilities, 37 in Housekeeping/Custodial Janitorial, 23 in HVAC Maintenance/Repair.
ISG operates overwhelmingly as a prime contractor and built its own delivery teams. Across 42 SCI-reportable prime contracts in FY2023 (the only year with invoiced revenue in the source), ISG reported $7.7 million invoiced across 42.5 FTEs, yielding a median government-paid hourly rate around $98.35 per hour, with rates spanning a 10th percentile of $47.42 per hour through a 90th percentile of $261.60 per hour. The SCI dataset captures only federal service contracts above the $150,000 threshold and excludes goods and classified work, so these figures represent a partial and conservative view of ISG's federal services footprint. Sub-engagement on prime contracts was negligible in SCI reporting (0% sub-hours share); ISG subcontracts occasionally — recent sub awards show work under Aktarius LLC prime for HVAC systems, boiler repairs, chiller repairs, and building renovations — but the sub footprint is minor relative to prime volume.
The corporate structure includes a subsidiary, Terranul LLC, also minority-owned and SBA 8(a) certified, though the source does not clarify operational separation or specific mission. ISG's 8(a) certification expires November 25, 2026, triggering a decision point for certification renewal or transition to full-and-open competition. The combination of heavy 8(a) set-aside reliance, strong Army Reserve and CBP relationships, and large standing vehicle positions on Army, Navy, and GSA schedules positions ISG as an incumbent-oriented, facilities-operations-focused federal contractor with near-term recompete exposure across mid-tier multiyear contracts and a significant post-November-2026 strategic inflection if 8(a) status lapses.
