About Leidos Holdings, Inc.

Written by GovTribe AI ·

Leidos Holdings, Inc. operates as a prime federal contractor (85% of recent awards) and subcontractor delivering research and development, engineering analysis, professional services, and IT systems to defense, health, and civilian agencies. The company competes in full-and-open and set-aside vehicles without a dominant SBA certification posture; recent awards span R&D services (12 awards under Defense Other categories), professional expert-witness support (6 awards), educational services (4 awards), and IT solutions (3 awards).

Leidos Holdings serves 13 distinct federal customer agencies across a portfolio heavily concentrated in two agencies by dollar value. The Pension Benefit Guaranty Corporation anchors the top potential-value ranking with 3 awards worth $229.9 million combined — substantially larger than the second-ranked customer. The Department of Health and Human Services Office of the Assistant Secretary for Preparedness and Response holds 4 awards valued at $49.4 million combined. By award count, the Department of the Navy Bureau of Medicine and Surgery leads with 14 awards ($20.2 million combined potential value), reflecting a different concentration pattern — multiple smaller orders rather than large anchors. The Department of the Navy Naval Air Systems Command, the Department of the Army Materiel Command, and the Office of the Secretary of Defense round out the active customer set, indicating persistent Navy and Army exposure alongside civilian health and benefits work.

Leidos places task orders under five named parent vehicles. The indefinite delivery contract W911QY09D0040 carries 14 task orders worth $20.2 million (Navy medical and life sciences work), and PBGC01D130007 holds 2 task orders worth $89.9 million (pension benefits systems). The vehicle HHSO100201100022I with HHS carries 3 task orders valued at $9.4 million. A contract with the Navy (N0042118D0028) supports 2 task orders, and One Acquisition Solution for Integrated Services (OASIS) — Small Business hosts 1 task order.

Activity has remained sparse and inconsistent over the source period — averaging fewer than two awards per year across the past five years, with no year exceeding four awards. The most recent award dated May 24, 2025 (less than two months prior to the source snapshot). The portfolio carries $322.2 million in combined potential value with $100 million obligated (31% of potential), suggesting most awards remain in execution rather than completion.

Leidos subcontracts to Parsons Government Services Inc. on missile defense systems engineering and aerospace defense ground environment support, to Axient LLC on services exercise options, and to Precise Systems, Inc. on programmatic support and management services. The company also receives work as a subcontractor on APL/UW FY2020–2025 requirements work.

Leidos Holdings maintains a corporate structure of 78 subsidiaries including multiple operating entities named Leidos, Inc., Eagan, Mcallister Associates, Inc., and Applied Marine Technology, Inc., indicating a multi-brand service portfolio spanning engineering, technology, and specialized technical services to defense and civilian agencies.
