Amentum is a $13 billion government services company specializing in operations and maintenance for the Department of Defense, Department of Energy, and other federal agencies. Spun off from AECOM's government services division, it operates across more than 35 countries and supports some of the most complex government programs in the world. That scale creates real supplier opportunities, but it also means competition is stiff and the process is formal.
If you run a diverse or small business and want to work with Amentum, the path starts with understanding what they actually buy, how their supplier registration works, and what certifications move the needle.
What Amentum buys from external suppliers
Amentum's business is operations and maintenance, so their external spend reflects the trades and professional services that keep large facilities and programs running.
Common procurement categories include:
- Facilities maintenance and construction trades (electrical, HVAC, plumbing, roofing, civil)
- Environmental and hazardous waste services
- IT support, cybersecurity, and managed services
- Engineering and technical staffing
- Logistics, warehousing, and fleet services
- Training and professional development
- Office and administrative supplies
- Safety equipment and personal protective equipment
The heaviest spend tends to cluster around subcontracting on large DoD and DoE base operations contracts. If Amentum holds a prime contract to manage a military installation or a nuclear facility, they typically flow a portion of that spend down to local and small businesses, often because federal subcontracting plans require it.
That federal obligation is the most important structural fact for any diverse supplier to understand. Amentum's prime contracts often include mandatory small and diverse business subcontracting goals. When those goals are written into the contract, their procurement team has a concrete reason to find qualified diverse suppliers. Your certification is not just a marketing credential in that context. It is a line item in a compliance report.
How to register as a supplier
Amentum maintains a formal supplier registration portal. To find it, search for "Amentum supplier portal" or navigate to the procurement or supply chain section of their corporate website at amentum.com. The portal is the required entry point. Cold outreach without a registration on file is unlikely to produce results.
When you register, expect to provide:
- Legal business name, DUNS/UEI number, and SAM.gov registration status
- Business classification details (small business, woman-owned, veteran-owned, etc.)
- NAICS codes for your primary service categories
- Capability statement or company overview
- Certifications held, including issuing body and expiration date
- Insurance certificates and bonding capacity where applicable
- References from prior government or large-prime work
SAM.gov registration is effectively a prerequisite. Amentum is a federal contractor, and their procurement processes are built around the federal supplier ecosystem. If you are not registered in SAM.gov, get that done before you approach their portal. Registration is free and takes one to three weeks for new applicants.
Which certifications carry the most weight
Amentum participates in NMSDC, WBENC, NaVOBA, and Disability:IN. Each of these maps directly to a category of supplier diversity their procurement team is measured on.
NMSDC certification (MBE) is among the most recognized credentials in corporate supplier diversity. The certification process involves ownership and control verification by a regional NMSDC affiliate. For businesses selling to Amentum's commercial-adjacent programs or working with their corporate supply chain teams, MBE status is a high-signal qualifier.
WBENC certification (WBE) follows a similar third-party verification process through regional WBENC partner organizations. Women-owned businesses pursuing subcontracting opportunities on Amentum's federal contracts may also want to hold the SBA's WOSB certification, since federal WOSB set-asides are a statutory procurement tool, not a voluntary one.
NaVOBA certification (VBE) applies to veteran-owned businesses. On the federal side, the VA's CVE program and the SBA's SDVOSB designation are the statutory certifications that unlock set-aside work. NaVOBA is the corporate-side equivalent and is recognized in Amentum's diversity supplier program. If you are veteran-owned, holding both NaVOBA and the federal SDVOSB designation is the strongest possible positioning.
Disability:IN certification (DOBE) is less common and therefore can differentiate you in a supplier base where most businesses hold one of the more familiar credentials. Disability-owned business certification through Disability:IN is accepted by Amentum and signals a commitment to a broader definition of diversity.
Of the four, NMSDC and WBENC tend to have the broadest internal recognition at large federal contractors. If you can hold only one and your work falls into professional services or trades, start with whichever matches your ownership status.
How certification status affects your chances
Certification does not guarantee a contract. What it does is get you past the first filter.
When an Amentum program manager or subcontracting manager is building out their small business subcontracting plan, they search an internal or external database of verified diverse suppliers. If you are not in that database with a valid certification on file, you do not appear in the search. The opportunity passes to someone who is.
Once you are in the database, certification status affects where you land on the shortlist. A business with an active NMSDC or WBENC certification from a recognized regional affiliate carries more weight than one with a self-certification or a state-level cert that is less familiar to a federal procurement team.
The businesses that consistently win subcontracting work also tend to have relevant past performance. Certification opens the door. A clean capability statement, verifiable references, and realistic pricing close it.
How to get your first order
Getting registered and certified puts you in position. Moving from registered supplier to active vendor requires more direct effort.
Start by identifying which Amentum contract vehicles or programs align with your NAICS codes. Their prime contracts are public record. Search the Federal Procurement Data System (FPDS) or USASpending.gov for Amentum as the awardee, filter by relevant agency (Army, Navy, DoE, Air Force), and look at what programs they operate. That tells you which program offices are likely to subcontract in your area of work.
Request a capability briefing with their supplier diversity team. This is a standard practice in the federal contracting space. A 30-minute call where you walk through your capabilities, certifications, and past performance is how you get moved from "registered" to "known to the team." Ask specifically about upcoming solicitations or teaming opportunities in your NAICS categories.
Consider teaming arrangements on new bids. If Amentum is responding to a competitive RFP and needs small business subcontracting commitments, they may be open to including a qualified diverse subcontractor they have not worked with before, provided the capability match is clear and the risk is low.
Follow their presence at industry events tied to the certifying bodies they participate in. NMSDC's annual conference, WBENC's Summit and Salute, and NaVOBA's events are all venues where Amentum's procurement and supplier diversity teams engage directly with potential suppliers.
Who handles supplier diversity at Amentum
Amentum has a dedicated supplier diversity function, typically led by a Director or Manager of Supplier Diversity within their supply chain or subcontracts organization. Program managers at the contract level also carry responsibility for meeting small business subcontracting plan goals, so your target contacts span both corporate staff and program-level subcontracts managers.
When reaching out through their supplier portal or after a conference introduction, ask to speak with someone in supplier diversity or small business programs. These contacts can route your profile to the right program teams and flag you when relevant opportunities arise.
Supplier development programs and industry events
Amentum participates in supplier diversity matchmaking events hosted by the certifying bodies they belong to. NMSDC regional affiliate business opportunity fairs, WBENC's national conference, and DoD-sponsored small business events are all forums where their team actively meets suppliers.
Watch for announcements about their own supplier days or industry days, which are sometimes posted on their website or through federal contracting notice boards like SAM.gov (under "Pre-solicitation" notices). These events are designed to introduce potential suppliers to specific program needs before formal solicitations open.
Amentum's scale as a government services prime puts real subcontracting dollars within reach of qualified diverse businesses. The process is formal and competitive, but it is also structured in a way that creates repeatable entry points. Getting your certifications current, your SAM.gov registration active, and your capability statement sharp before you submit your portal registration puts you ahead of most of the field.
