How to verify an advisor's track record
Ask for a closed deal list filtered to your sector and deal size range.
In DC, that means GovCon sell-sides with named buyers and close dates. Vague portfolios with no buyer names are a red flag.
Check if the advisor has handled classified data room structures before. Not every M&A firm knows how to handle cleared documents in due diligence.
Use Ellty to share your contract backlog and cleared headcount summary with shortlisted advisors. Track who opens the file and how long they spend before your first meeting. Read the Washington DC aerospace and defense guide alongside this list.

GovCon valuation drivers in DC
Contract backlog quality matters more than revenue in GovCon valuation.
Buyers price the percentage of cost-plus vs. fixed-price contracts. Fixed-price risk stays with you at close if margins are thin.
Cleared headcount is a premium asset. Firms with active TS/SCI personnel get higher multiples than equivalent-revenue firms without clearances.
Read our financial due diligence checklist before talking to any buyer. Knowing what drives your multiple changes how you present your business.
Set-aside risk and recertification
Small business set-aside status changes after acquisition. The SBA's 2025 recertification rule affects every small GovCon sale.
Buyers now price set-aside exposure at the LOI stage. Don't wait for diligence to surface it.
If more than 40% of your revenue is set-aside dependent, expect buyers to discount heavily. Disclose it early and let advisors negotiate the risk into price.
Use Ellty to share your set-aside contract list with buyers under NDA before LOI. Buyers who proceed after reviewing it are serious. See our data room checklist for how to organize sensitive contract documents.
How security clearances affect deal timelines
Cleared facilities and personnel require DCSA notification at close. This adds steps that non-GovCon deals don't have.
Defense deals with multiple facility clearances can take three to six extra weeks at close. Budget for it in your deal timeline.
Novation agreements for cleared contracts need government approval post-close. Your advisor should know the standard novation timeline for your agencies.
Use Ellty with link-level password protection to share cleared personnel rosters only with verified buyers. Dynamic watermarking tracks every download during due diligence.

Common questions about Washington DC M&A advisors
- Most DC advisors specialize in GovCon and defense tech. They understand cleared personnel, contract novation, and set-aside risk in ways general M&A firms don't.
- Most deals run nine to fourteen months. Security review steps and novation agreements add time not found in other markets.
- Expect three years of financials and a full contract backlog by agency and vehicle. Cleared headcount and facility clearance status come next.
- Buyers discount heavily if more than 40% of revenue is set-aside dependent. Disclose it before LOI - not during diligence.
- Before your first advisor meeting. Organized contract data signals you're ready to move. Disorganized data rooms slow every deal stage.
- Yes. FOCUS Investment Banking and Glover Park Capital cover commercial tech, business services, and healthcare IT alongside government services.
