The Cost of CMMC Non-Compliance: What Defense Contractors Can Lose

You open an email from your prime contractor on a Tuesday morning and are presented with something you’ve been dreading for months, if not years.

They're restructuring their vendor list. Effective immediately, they need verified CMMC compliance from all subcontractors handling defense data, and you have 30 days to provide documentation or you'll be removed from the project.

For the subs who were ahead of the game, this is golden news. You’re one of only a handful of CMMC Level 2 certified options that primes can rely on. For the others? It’s make or break time.

CMMC non-compliance doesn't show up as a fine or a warning letter. It shows up as a lost contract, a rejected bid, or a phone call you weren't expecting.

The companies that think they can deal with this later are the ones discovering the hard way that later has already arrived. Phase 1 enforcement went live November 10, 2025. Phase 2 arrives November 2026. The window to get ahead of this is closing fast, and the cost of waiting is a lot higher than most contractors realize.

What to Take Away

CMMC non-compliance costs you contracts you already have, bids you'll never get a shot at, and possibly legal exposure you didn't know existed. For subcontractors especially, the bigger risk may be the growth opportunity passing you by as certified competitors lock up prime supply chains. This post breaks down every real cost category so you can make an informed decision about what to do next.

What Does Non-Compliance Actually Cost You?

CMMC non-compliance is enforced at the contract level. If a solicitation requires a verified CMMC status and you can't provide it, your proposal is rejected outright. Your existing contracts may lose option periods, and your prime contractor has both the right and the obligation to remove you from their supply chain.

Think of it less like a parking ticket and more like a license revocation. You don't get a fine. You just can't work.

CMMC rolled out in phases, and here’s a brief overview of where things stand now.

Phase 2 is the one that will hit most subcontractors hardest. That's when independent third-party C3PAO certification becomes required for any contractor handling Controlled Unclassified Information (CUI). And it takes 18 to 24 months to implement from scratch.

The Direct Cost: Losing Contracts You Already Have

Defense contractors with existing DoD work are not protected by the contracts they've already signed. When option periods come up for renewal, CMMC compliance becomes a condition of award. If your SPRS score (the DoD's Supplier Performance Risk System) is missing, inaccurate, or fails to meet the required level, contracting officers can and will flag your record.

For companies where one or two contracts represent the majority of annual revenue, this becomes a massive threat to your business.

Here's what a contracting officer sees when they pull your SPRS record, and what raises red flags:

• A missing SPRS score (means no self-assessment has been submitted)
• A score that seems high relative to your apparent security posture (flags potential misrepresentation)
• No record of annual affirmation from a senior company official
• A score submitted years ago with no updates (raises questions about ongoing compliance)
• No Plan of Action and Milestones (POA&M) on file to address known gaps

For companies with long-standing DoD relationships, losing a contract renewal this way is particularly damaging. You built that relationship over years, just for CMMC non-compliance to end it in days.

The Opportunity Cost: The Work Going to Someone Else

This is the cost that doesn't show up on any invoice, but it's often the biggest one. CMMC certification is creating a visible dividing line in the defense supply chain. Prime contractors are actively building certified vendor networks right now. The subcontractors who get certified first are the ones who get called first, and they're going to keep earning that business.

If your company isn't doing a ton of defense work today, this might feel abstract. But here’s something to keep in mind:

Roughly 220,000 contractors and subcontractors are in the defense supply chain. Industry estimates suggest only about 1% are fully prepared for Phase 2 certification.

That gap is an enormous market opportunity for the companies that move now. Someone in your industry is going to get CMMC-certified and become the preferred sub for three, five, or ten prime contractors.

Meanwhile, the companies that waited are scrambling to get compliant under deadline pressure, paying more for it, and hoping their primes haven't already found a replacement.

Here are some of the opportunity costs you’re risking:

• Eligibility to respond to DoD solicitations that non-certified subs are automatically excluded from
• A verified SPRS score that primes can check before even reaching out, putting you on shortlists before bids open
• The ability to handle CUI, which opens you up to higher-value, higher-complexity contract work
• A competitive differentiator that becomes more powerful as enforcement tightens through 2027 and 2028
• Trust from prime contractors who know a certified sub won't put their own compliance status at risk

The defense industry is not getting smaller. DoD budgets continue to grow, and supply chain demand for certified contractors is going to increase every phase.

The Supply Chain Cost: When Your Prime Makes the Call for You

Prime contractors are legally required under DFARS 252.204-7012 to ensure that every subcontractor handling defense data meets CMMC requirements. If you're out of compliance, the prime's options are narrow: document a plan to bring you into compliance quickly, or replace you.

Many subcontractors assume the prime's CMMC certification covers them, which is not true. Each legal entity that processes, stores, or transmits FCI or CUI is responsible for its own compliance. The prime's certification protects the prime. Your gaps are your problem, and when the prime discovers them, your gaps become their problem too.

That dynamic changed significantly in December 2025, when the DOJ announced its first FCA enforcement action directly targeting a subcontractor: a precision machining shop in Illinois that agreed to pay approximately $421,000 for failing to protect CUI technical drawings it supplied to prime contractors.

That settlement sent a clear message to every subcontractor in the defense supply chain: the government is not limiting enforcement to primes. They're working their way down the supply chain, and the cases are starting to come from inside the companies themselves.

Our IT compliance services are built specifically to help defense contractors and their subs navigate this process without falling behind or getting caught off guard by their prime.

The Legal Cost: When Non-Compliance Becomes Fraud

If you've submitted an SPRS score or signed an annual CMMC affirmation that doesn't accurately reflect your actual security posture, you may already have False Claims Act (FCA) exposure. Under 31 U.S.C. Section 3729, "knowingly" includes reckless disregard of the truth. Claiming compliance without verifying it meets that standard.

The Department of Justice's Civil Cyber-Fraud Initiative was created specifically to pursue this kind of exposure. It launched in 2021 and has been ramping up every year since. In fiscal year 2025, the Initiative recovered $52 million from cybersecurity-related settlements, up from $36 million across the prior three years combined.

The era of "self-certify and hope no one checks" is over. Our managed cybersecurity services include the documentation, monitoring, and audit support that keeps your SPRS score accurate and your affirmations defensible.

To really hammer it home, here’s a few settlements that happened in 2024 and 2025. Several were triggered not by government audits, but by current or former employees who knew what was actually in place and what wasn't.

The Raytheon case is particularly instructive. One of the most recognized defense contractors in the world had no System Security Plan on a key internal network, across 29 separate DoD contracts. A former Director of Engineering blew the whistle. The company settled for $8.4 million, and the whistleblower received over $1.5 million for coming forward.

If Raytheon got caught, smaller contractors who assume they're below the radar should think carefully about that assumption. The whistleblower provisions of the FCA make enforcement highly decentralized. Anyone inside your company who knows about a compliance gap is a potential enforcement vector.

Compliance Is the Cheaper Path

Every cost we've covered in this post is avoidable. The contractors who move now get to keep their current work, pursue new opportunities, and build a reputation as a trusted, certified partner in the defense supply chain. The ones who wait are going to pay a higher price to catch up, and some won't get the chance.

CMMC compliance is a real business decision with real financial consequences on both sides. The question isn't whether you can afford to get compliant; it's whether you can afford not to.

Frequently Asked Questions

What happens if I fail a CMMC assessment?

A failed CMMC assessment means you don't receive certification at the required level. For contracts that specify CMMC as a condition of award, you'll be ineligible to bid until you achieve certification. You may also lose option periods on existing contracts. If you submitted a self-assessment score claiming compliance, a failed third-party assessment can also create False Claims Act exposure depending on how your score was reported.

Can I submit an SPRS score before I'm fully compliant?

You can submit a score that reflects your current implementation level, but you cannot submit a score that misrepresents where you actually are. Inflated SPRS scores are one of the primary FCA enforcement triggers. A lower but accurate score is far safer than a high score that doesn't reflect reality. If there are gaps, document them in a Plan of Action and Milestones (POA&M) and remediate systematically.

How much can CMMC non-compliance actually cost in penalties?

FCA penalties for cybersecurity misrepresentation include civil fines of up to $28,619 per false claim in 2025, plus triple the damages the government sustains. Because each of the 110 NIST SP 800-171 controls at Level 2 can represent a separate potential violation, total exposure can reach into the millions before accounting for legal fees or remediation costs. Recent settlements have ranged from $421,000 for a small subcontractor to $11.25 million for a managed care provider.

How long does it take to get CMMC Level 2 compliant?

Level 2 implementation typically takes 18 to 24 months from scratch. That includes gap assessment, scope reduction, control implementation across all 110 NIST SP 800-171 requirements, System Security Plan documentation, and scheduling a C3PAO assessment. C3PAO availability is limited and the backlog is growing, so early engagement matters.

Does CMMC still matter if I don’t have any current defense contracts?

Yes, and this is exactly the scenario where CMMC matters most strategically. If your company is on the edge of the defense supply chain today, getting certified now positions you to grow into it. Prime contractors are actively building certified vendor networks, and they're looking for reliable, compliant subs. A CMMC certification today is a competitive differentiator that becomes more valuable every phase of enforcement.
