Selling a defense contracting business is not like selling any other company, and finding the best broker for defense contractors is one of the most consequential decisions you’ll make in the process. The advisor you hire either speaks this language or they don’t, and you’ll find out at the worst possible moment. Some generalist M&A advisors lack govcon-specific experience, they can’t explain what a novation agreement is, have never dealt with a Facility Clearance transfer, and wouldn’t know where to start with a FOCI mitigation strategy. That’s not a small gap. It’s the difference between a clean close and a deal that drags past a year, loses a buyer, or collapses in due diligence.
This guide gives you a clear comparison framework for finding the right sell-side advisor for your defense contracting business, someone who understands prime contractor demands, government contract structures, and the regulatory complexity that governs every deal in this space. The goal is to help you shortlist the right advisor before you ever take your business to market.
What separates a defense-specialized broker from a generalist M&A advisor
Generalist M&A advisors often evaluate defense contractors the way they evaluate a manufacturing firm or a staffing company, and when they do, they risk missing the variables that actually drive value and risk. Contract type (cost-plus vs. fixed-price), cleared workforce concentration, IDIQ vehicle access, and NAICS code diversity are often overlooked by advisors without GovCon experience. You end up spending your own time educating the person who is supposed to be guiding you.
A qualified advisor looks different. Their buyer network includes defense-focused private equity firms like Veritas Capital and AE Industrial Partners, and strategic acquirers like SAIC and TransDigm. They understand FAR Subpart 42.12 novation requirements without having to look them up. They read your set-aside certifications, whether that’s SDVOSB, 8(a), or HUBZone, as valuation inputs, not footnotes.
The red flags are easier to spot than you’d think. No closed defense transactions in the past 12 to 24 months, unfamiliarity with DFARS compliance, no existing relationships with buyers who have completed DCAA-audited govcon acquisitions. Any one of these signals that the advisor isn’t equipped for this transaction. All three together? Walk away.
How to choose the best broker for defense contractors: The criteria that actually matter
A broker’s most recent closed deals tell you almost everything. You’re looking for transactions that match your size, your sub-sector, and your cleared status. A firm that closed a $200M aerospace prime deal is not necessarily equipped to handle a $15M 8(a) services company. Closed deal count within your deal range, not total revenue under management, is the right metric.
Buyer network depth
Buyer network depth matters just as much as deal history. The best broker for defense contractors already has relationships with the buyers most likely to pay a premium for your specific contract profile: cleared integrators, defense-focused PE platforms, and prime contractors building subcontractor capacity. Ask directly which buyers they’ve introduced to similar transactions in the past 18 months. If they hedge or generalize, that’s your answer.
Closed-deal match and fee structures
Fee structures follow a predictable pattern in this market. The Modified Lehman Formula is standard for middle-market transactions, with monthly retainers typically running between $15,000 and $50,000, often credited against the success fee at close. For deals in the $10M to $25M range, expect a success fee of roughly 4 to 5 percent. For $25M to $50M, expect 2.5 to 4 percent. Understanding which percentage applies at your deal size, and whether a minimum fee floor applies, prevents surprises after you’ve already signed an engagement letter.
Key criteria the best broker for defense contractors uses to evaluate a transaction
A qualified DOD contractor broker or defense M&A advisor brings more than a contact list. They evaluate your contract portfolio through a buyer’s lens: incumbency strength, option-year visibility, ceiling utilization on IDIQ vehicles, and the transferability of cleared personnel. These are the variables that determine whether a strategic acquirer pays a premium or walks away. A generalist advisor working without govcon fluency often can’t frame these variables in diligence materials at all.
When you’re interviewing firms, ask each one to walk you through a comparable deal they’ve closed. A government contractor broker who has done this before will describe the buyer pool they ran, the diligence issues that surfaced, and how they were resolved. Vague answers about “broad networks” and “strategic relationships” are not answers.
Notable firms that have closed defense contractor deals
For deals under $150M, which covers the vast majority of small-to-mid GovCon businesses, boutique firms are often more relevant than generalist investment banks for sub-$150M govcon transactions. They tend to have more focused buyer relationships, leaner deal teams, and advisors who work defense M&A full-time rather than as one vertical among many.
Several aerospace and defense business broker firms have active, verifiable track records in this space. KippsDeSanto advised on SilverEdge’s $205M sale to SAIC in October 2025. The McLean Group sold Blue Force Technologies to Anduril and has closed multiple govcon IT transactions, including SITE Intelligence and CollabraSpace to Arlington Capital. Harris Williams advised Raptor Scientific on its acquisition by TransDigm and Excelitas Technologies on the sale of select aerospace and defense electronics businesses to Teledyne. FOCUS Investment Banking facilitated the acquisition of Sev1Tech in early 2026. These aren’t name drops. They’re signals of which buyer relationships each firm can actually activate.
A sub-$25M deal often receives more focused attention and advocacy at a mid-market boutique that targets that range than at a firm focused on $500M+ transactions. Clarity about deal size is the fastest filter when building your shortlist.
What defense contractors can realistically expect in valuation
Valuation ranges in this sector vary more than most sellers expect. Here’s a quick breakdown by profile and deal size, based on current market data:
- Prime contractors with direct DoD incumbency: 9x to 16x EBITDA
- Government IT services firms with cleared workforces: 11x to 16x EBITDA
- Defense services companies with labor-intensive, non-tech profiles: 4x to 6x EBITDA
- Deals under $10M EBITDA: typically 6x to 8x
- Deals in the $25M to $50M EBITDA range: typically 10x to 14x
The biggest value drivers are contract incumbency, cleared workforce concentration, and access to IDIQ or GWAC vehicles like OASIS+. Earn-outs are standard in mid-market transactions and are typically tied to contract renewal milestones or revenue retention targets. Retention agreements for cleared staff, especially those holding TS/SCI, are common and expected by buyers. Working capital adjustments are routine given milestone-based billing cycles in government contracts. Non-competes are stricter in govcon than in most other sectors. Understanding these terms before you sit at the negotiating table prevents costly surprises.
The regulatory hurdles that delay or kill these deals
The Anti-Assignment Act (41 U.S.C. § 6305) prohibits transferring a government prime contract to a new entity without written government consent. Every active contract you hold must go through a novation process under FAR Subpart 42.12. This is documentation-intensive and adds real time to your timeline. For a typical defense portfolio with multiple agencies and classified performance requirements, expect 90 to 180 days from submission to execution, and that’s if everything is filed correctly the first time.
If your buyer has any foreign ownership or affiliates, CFIUS review is likely. Even a 5 percent foreign ownership stake triggers FOCI disclosure via SF-328. A change of ownership that jeopardizes the company’s Facility Clearance can make certain buyers ineligible entirely. CFIUS reviews can add several months between signing and close, with the exact timeline varying significantly by transaction complexity and whether mitigation obligations are required.
Non-compliance with CMMC 2.0 or DFARS 252.204-7012 is consistently cited as a deal-stopper in due diligence. State Department notification is required when ITAR-registered companies change ownership. These aren’t post-close issues. They surface in diligence and directly affect whether a buyer proceeds at all. A well-prepared defense contractor sale runs 9 to 14 months from market launch to close, and that timeline assumes you start prepared.
Getting deal-ready before you engage a broker
Before any federal contractor sell-side advisor takes your business to market, buyers will examine three things beyond your financial statements: your contract compliance posture, your overhead and cost accounting structure, and your insurance program. Gaps in any of these areas surface in diligence and either reduce your price or delay your close. Many sellers focus entirely on the financials and underestimate how much a disorganized compliance file can slow a deal.
Insurance compliance is often overlooked by sellers and merits serious attention before you go to market. Buyers and their counsel review your certificates, your coverage limits, and whether your programs align with your contractual obligations across every active contract. For defense contractors, this means DBA coverage, prime contractor-demanded liability limits, and NAICS-code-specific programs that reflect your actual scope of work.
Risk Reconnaissance LLC operates in this specific gap. The Atlanta-based brokerage works exclusively with government and defense contractors, which means their team already understands what prime contractors require at the proposal stage, what coverage structures hold up under buyer scrutiny in due diligence, and how to document an insurance program that doesn’t slow your timeline. A clean, well-documented insurance program signals to buyers that your compliance house is in order, and that signal has real value when you’re trying to close at the top of the valuation range.
The decision that shapes everything else
Choosing the best broker for defense contractors starts with preparation and the right closed-deal track record. The right sell-side advisor is not the one with the biggest name or the broadest M&A experience. It’s the one who has closed deals in your size range, understands the regulatory environment your buyer will inherit, and can communicate your contract value clearly to the right buyer network.
Start with the criteria above. Filter by closed-deal track record in your sub-sector. Ask the hard questions about FOCI, CFIUS, and novation experience. And before you ever sit across from a broker, make sure your house is in order, including your insurance program, your compliance documentation, and your cost accounting structure.
The contractors who sell at the top of the valuation range aren’t just lucky. They show up prepared, with the right govcon M&A advisor in their corner and a compliance file that holds up under scrutiny. That preparation starts before the first broker call, not after.
