Mergers and acquisitions in the government contracting space has become a hot trend lately.  It appears they are driven by the same simple premise to acquire capability (or expand footprint) to grow revenue. But in today’s federal market, cybersecurity standards are tightening, and that means the newly formed entity may introduce cyber risks that threaten their ability to perform, or even hold onto, existing contracts.

For GovCon executives, this means cybersecurity has become a deal-defining variable for navigating M&A.

Buyers Are Paying for Cyber Capability, which Includes Inheriting Cyber Liability

Acquirers aren’t just buying contract vehicles anymore. They’re buying what the company actually does with a mature AI solution, advanced cyber tools, hardened infrastructure, and/or a cleared technical workforce. These capabilities command real value to buyers. However, they could also deliver hidden liabilities in the seller’s cybersecurity compliance posture.

With FAR and DFARS updates continuing to elevate cyber standards, acquirers are under pressure to scrutinize companies against frameworks, including CMMC (Cybersecurity Maturity Model Certification), NIST SP 800-171, and supply chain security requirements.  A gap in any of these doesn’t just create a remediation cost, it can disqualify the merged entity from performing on contracts that require specific certifications, sometimes immediately after close.

CMMC Gaps Don’t Stay Hidden for Long

CMMC has introduced a new layer of operational risk into GovCon M&A.  When a company is acquired, the new (combined) entity must meet the cybersecurity certification level required by the contracts it holds.  That applies to the whole organization, not just the legacy entity that originated the work.

If the acquiring firm hasn’t achieved the required CMMC level, or if the selling company was operating with undocumented workarounds, the merged company may find itself unable to perform on DOD contracts until a formal certification is achieved. And as every GovCon knows, that process takes time, money, and focus, which can be a daunting task to deliver in the middle of an integration.

The Problem Isn’t the Vulnerability You Know About

Most executives understand how to evaluate obvious cybersecurity risks. The bigger challenge is identifying the ones that aren’t immediately visible.

• An outdated System Security Plan.
• A weak NIST SP 800-171 implementation.
• A self-assessment that paints a more optimistic picture than reality.
• An undocumented workaround that helped the company pass an audit but won’t survive deeper scrutiny.

Beyond Vulnerabilities:  the Cyber Compliance Liability You Didn’t Know You Bought

One of the most consequential cybersecurity risks in GovCon M&A isn’t a technical vulnerability, it’s a legal one. The new entity’s liability comes when a company is acquired, and the buyer inherits the compliance failures that predate the transaction.  For federal contractors, this includes potential False Claims Act (FCA) violations tied to misrepresentations about cybersecurity compliance.

The Department of Justice’s Civil Cyber-Fraud Initiative has made clear that contractors who falsely certify their compliance with federal cybersecurity requirements can face significant FCA exposure. If the selling company has been attesting to NIST or CMMC compliance without fully meeting the standard, the acquiring firm can step directly into a liability they are unprepared to handle.  This also can spell trouble even if the violations occurred years before the deal.

Cybersecurity due diligence and well-structured indemnification provisions aren’t optional safeguards. They’re the difference between a successful acquisition and an inherited legal crisis.

The Risk Beyond the Merger – Supply Chain Security

Beyond the selling company’s internal compliance posture, buyers must also assess supply chain security. Federal requirements increasingly hold prime contractors responsible for the cyber hygiene of their subcontractors and technology vendors. An acquisition with third-party dependencies that fail to meet federal standards can expose the new entity to contract performance issues, audit findings, and potential award disqualification.

Cybersecurity Due Diligence Must Happen Before the Deal Closes

GovCon acquirers should not treat cybersecurity as just an integration task.  By the time the deal closes, it is too late to renegotiate a new price for CMMC gaps, an FCA exposure, or a critical supply chain liability.

GovCon acquirers should include a cyber compliance review early in the deal process:  assess CMMC readiness, review NIST self-assessment scores, audit subcontractor relationships, and map certification requirements against every contract in the seller’s portfolio.

In this new trending M&A market where the premium is on what a company can do, acquirers can have a positive outcome by taking some time to understand the cyber risk that comes with the deal.

Frequently Asked Questions About Cybersecurity in GovCon M&A

What cybersecurity risks should government contractors evaluate during an M&A deal?

Government contractors should evaluate several layers of cyber risk before closing an acquisition. These include gaps in CMMC certification, the strength of the seller’s NIST SP 800-171 implementation, the accuracy of self-assessment scores, and whether any undocumented workarounds exist that could fail deeper scrutiny. Supply chain security is equally important, as prime contractors can be held responsible for the cyber hygiene of subcontractors and vendors the acquired company brings with them.

How does CMMC compliance affect mergers and acquisitions in the defense contracting industry?

When two companies merge, the combined entity must meet the CMMC certification level required by every contract it holds, not just the contracts from the company that originally earned them. If either party has unresolved CMMC gaps, the merged organization may be unable to perform on existing DOD contracts until formal certification is achieved. That process takes significant time, money, and operational focus, making pre-deal CMMC due diligence critical to a successful integration.

Can a company inherit False Claims Act liability from a cybersecurity compliance failure after acquiring another federal contractor?

Yes. Under the Department of Justice’s Civil Cyber-Fraud Initiative, contractors who falsely certify compliance with federal cybersecurity requirements face serious False Claims Act exposure. When a company is acquired, the buyer can inherit that liability even if the misrepresentations occurred years before the deal closed. Thorough cybersecurity due diligence and well-structured indemnification provisions in the purchase agreement are essential protections against stepping into a legal crisis after close.
