Kroll, LLC

Kroll, LLC, doing business as Duff & Phelps, is a for-profit professional services firm headquartered in New York that sells expert witness testimony, litigation support, forensic accounting, and financial advisory services to federal agencies as a prime contractor on a full-and-open competitive basis, with no set-aside posture across its federal portfolio.

Kroll operates across 21 federal customer agencies with heavy concentration in litigation and financial advisory work. The top five customers by both award count and dollar potential account for 55% of recent awards and 74% of combined potential value. The Department of the Treasury's Internal Revenue Service dominates at nine awards worth $11.8 million combined potential value, reflecting Kroll's depth in tax litigation support and forensic accounting for IRS audit defense and expert witness testimony. The Department of Justice offices hold the second-largest share through three separate components: the Executive Office for U.S. Attorneys ($4.5 million across three awards, anchored by a $3.6 million document management solution integrator contract running through September 2026), the Tax Division ($3.8 million across seven awards), and the Justice Management Division ($3.7 million across four awards). The Securities and Exchange Commission rounds out the top tier with eight awards worth $2 million. Kroll's recent activity shows a modest trajectory — seven awards in 2022 declining to two in 2024 before recovering to four in 2025 — with six awards (combined potential value $8.3 million) reaching ultimate completion inside the next twenty-four months and facing recompete exposure.

Kroll's capability portfolio centers on PSC 21 Support Professional classifications: expert witness services account for 43 of 66 total awards, real property appraisals for six awards, and legal support for three awards. Representative prime work includes a $2.7 million labor-hours contract with the IRS (February 2025 through February 2030) for expert witness services in economics; a $1.15 million time-and-materials engagement with the Securities and Exchange Commission (September 2025 through September 2030) for expert witness services; a $3.18 million IRS contract (June 2022 through June 2027) covering expert witness testimony, forensic accounting analysis, and litigation support for audit defense and tax abatement; and a $1 million expert audit and subject matter expert support engagement with the Department of Defense (April 2025) for temporary power infrastructure analysis in Puerto Rico. Kroll also performs modest appraisal work — fair market value and annual rental appraisals for the General Services Administration National Capital Region and the U.S. Patent and Trademark Office — ranging from $4,500 to $50,000 per order. Recent work also includes an April 2026 definitive contract worth $775,160 with the U.S. Army Engineer District Transatlantic for eight phases of litigation support and expert services spanning two Armed Services Board of Contract Appeals appeals and one certified claim through April 2028.

Kroll holds a GSA Federal Supply Schedule contract (Multiple Award Schedule) expiring November 2026 with a $750,000 ceiling, offering four labor categories — Technical Consultant, Project Manager, Senior Consultant, and Managing Consultant — at fully burdened hourly rates spanning $253.52 to $323.64 with bachelor's degree minimums and no security-clearance requirements. The MAS vehicle complements Kroll's direct prime awards and provides task-order access to civilian agencies seeking IT professional services and technical consulting without formal competition.

Kroll's NAICS concentration reflects its service mix: All Other Legal Services (16 awards), Administrative Management and General Management Consulting Services (10 awards), Offices of Real Estate Appraisers (8 awards), Miscellaneous Intermediation (7 awards), and All Other Professional, Scientific, and Technical Services (7 awards). The corporate structure includes five named subsidiaries — Resolver Inc., Kroll Restructuring Administration LLC, Kroll Associates Inc., Kroll Settlement Administration LLC, and Kroll Securities LLC — which expand the parent entity's service reach into restructuring, settlements administration, and securities-related advisory work. With 66 prime awards (98% of the portfolio) against a single sub-award (a 2024 equipment supply order under Atlantic Diving Supply), Kroll operates predominantly as a direct federal prime contractor rather than through subcontracting relationships.
