Mercer (Us) LLC

Mercer (US) LLC, doing business as Mercer Delta Organizational Consulting, is a subsidiary of Marsh & McLennan Companies Inc. that delivers federal consulting services as a prime contractor (98% of recent awards) across compensation data analysis, healthcare benefits strategy, actuarial modeling, and human resources consulting. The vendor operates exclusively in full-and-open competition with no set-aside activity and is headquartered in New York, New York.

Mercer's customer concentration splits sharply between high-volume, low-dollar work and a single large vehicle holding most contract value. The top five customer agencies by award count (41% of awards) include the Bureau of Overseas Building Operations with 13 awards totaling $135 thousand, the Defense Contract Audit Agency with 6 awards, the Office of the Secretary of Defense with 5 awards, the Department of Health and Human Services Program Support Center with 5 awards, and the Defense Health Agency with 5 awards valued at $21.5 million combined. However, by dollar value, the ranking inverts: the GSA Federal Acquisition Service dominates with $114.5 million potential value across 2 awards, anchored by Mercer's General Services Administration Multiple Award Schedule contract (MAS 47QRAA21D004A), which carries a $4 million ceiling and has generated 13 task orders worth $30.3 million combined. The Defense Health Agency's $21.5 million in value across five delivery orders represents the second-largest customer by dollars; the remaining agencies contribute substantially in award volume but modestly in contract value. The concentration signal is extreme: GSA vehicles and Defense Health Agency work together account for 98% of combined potential value across all awards.

Mercer's representative federal work anchors in healthcare payment innovation and compensation benchmarking. A $1.72 million firm fixed-price delivery order from the Defense Health Agency (awarded January 2026, completing January 2027) provides Health Plan Innovation Support Task 1 Bridge services under the GSA MAS vehicle; this complements a $6.3 million Defense Health Agency delivery order for actuarial rate-setting services (awarded September 2025, extending through December 2028). A $490 thousand Defense Health Agency delivery order (awarded May 2024, completing October 2029) funds Health Plan Innovation Support Task 6 actuarial analysis of alternative payment models and risk adjustment. Outside Defense Health, the vendor supplies recurring compensation survey database subscriptions: the Transportation Security Administration holds multiple Mercer compensation database orders, including a $39.15 thousand option-period exercise for Fiscal Year 2023 U.S. Benchmark Database access (awarded September 2023, through August 2026), and a more recent $14.4 thousand subscription order (awarded September 2026, through September 2027). The Bureau of Overseas Building Operations has placed five purchase orders for general consulting and subscription services ranging from $11.95 thousand to $13.52 thousand per order. A $406.1 thousand definitive contract from the Pension Benefit Guaranty Corporation (awarded April 2022, completed December 2022) delivered peer review of PBGC's Pension Insurance Modeling System. The U.S. Agency for Global Media holds a $494.8 thousand delivery order for health benefits brokerage services running through November 2026.

Mercer's federal activity shows volatility: three awards in 2022, two in 2023, two in 2024, rising to six in 2025 and four in 2026 (with the source dated October 15, 2026). Five awards valued at $4.5 million reach ultimate completion in the next twenty-four months and represent recompete exposure. The vendor operates on the GSA MAS as its primary vehicle, with 13 task orders generating $30.3 million in combined potential value; a secondary Basic Ordering Agreement carries 1 task order. GSA Schedule labor rates span Analyst positions at $122.49 per hour through Senior Principal roles at $479.93 per hour, with representative mid-tier positions (Associate II, Senior Associate II) priced at $284–$329 per hour, and Principal-level consulting at $389–$480 per hour, all requiring bachelor's or master's degrees with no security clearance posture.

Service Contract Inventory data captures $523 thousand in SCI-reportable invoiced revenue across fiscal years 2022–2025 (FY2023 reported zero revenue), with FY2024 as the heaviest year at $264 thousand across 0.2 FTEs. The SCI dataset is sparse and represents only a fraction of the vendor's total federal revenue, which is dominated by non-SCI vehicles such as the GSA MAS and purchase orders. Mercer staff rates on federal service contracts median around $754 per hour, with 10th-percentile pricing at $460 per hour and 90th-percentile senior labor reaching $918 per hour. The vendor performed 0% of its SCI-prime hours through subcontractors; across the award footprint, Mercer operates as a subcontractor in only 2 of 82 awards (2%), subcontracting to Mission Support & Test Services LLC for actuarial services on a Department of Energy Nevada National Security Site contract (April 2026) and to Deloitte Consulting LLP for salary survey data and analysis supporting Department of Veterans Affairs total compensation analysis (January 2025). The vendor's sub-award footprint is negligible relative to its prime presence.
