When a DC business needs an M&A lawyer

The DC M&A market is concentrated around three industries that don't have the same weight elsewhere: federal contracting, regulated industries (telecom, healthcare, energy), and government-adjacent technology and cybersecurity. Add the antitrust agencies, CFIUS, DDTC, OFAC, and the FCC all being headquartered here, and DC M&A counsel routinely handle regulatory layers that aren't on the radar in New York or Boston deals of comparable size.

Covington, Hogan Lovells, WilmerHale, Fried Frank, Wilson Sonsini, King & Spalding, Skadden DC, Latham DC, and Arnold & Porter run the city's largest M&A practices. Mid-market work is handled by Shulman Rogers, Pillsbury, McGuireWoods, Holland & Knight, and Steptoe. Boutique DC corporate firms cover founder-led exits and middle-market transactions in the $10M–$200M range.

DC-specific deal mechanics:

  • CFIUS notice or declaration under FIRRMA for foreign-acquirer transactions
  • FOCI mitigation agreements (Special Security Agreement, Proxy Agreement) for cleared defense contractors
  • FAR Subpart 42.12 novation of federal prime contracts after closing
  • Security clearance transfers for cleared personnel and facilities
  • DCAA cost-accounting standards compliance during transition
  • FCC and state PUC approvals for telecom and utility deals
  • HSR antitrust filings reviewed by either DOJ Antitrust or FTC depending on industry
  • DDTC ITAR or EAR export-control approvals for defense-related technology
  • OFAC sanctions screening of buyers, sellers, and ultimate beneficial owners

Washington DC M&A Lawyers — FAQ

How much do M&A lawyers cost in Washington DC?
DC BigLaw M&A partners bill $1,100–$2,200/hr; senior associates $750–$1,300/hr. Mid-market DC and Maryland-suburban firms run $525–$1,050/hr. A typical $25M–$100M deal carries $300,000–$900,000 in legal fees. Add $250,000–$1.5M if CFIUS review is required, plus another $400,000–$2M if the FTC or DOJ Antitrust opens a second request.
Why is CFIUS such a big deal in DC M&A?
The Committee on Foreign Investment in the United States reviews acquisitions of US businesses by foreign buyers for national security risk. CFIUS sits at Treasury but coordinates Defense, State, Commerce, DHS, and intelligence agencies. Filing is mandatory for some technology, infrastructure, and personal-data transactions under FIRRMA. DC M&A firms with active CFIUS practices — Covington, Hogan Lovells, Wilson Sonsini, WilmerHale, King & Spalding — handle most of the heavy review work.
What industries dominate DC-area M&A?
Government services and federal contractors lead the market. Defense, aerospace, intelligence services, cybersecurity, government IT, and healthcare services concentrate around the Beltway. DC M&A counsel routinely handle the unique novation and assignment issues with federal prime contracts, security clearance transfers, and DCAA cost-accounting compliance during transitions.
How long do DC M&A deals take?
A typical middle-market DC deal closes 100–160 days from LOI. Federal contractor deals add 30–90 days for novation processing through the contracting officer. CFIUS review adds 45–90 days when a notice is filed (or up to 120 days if review extends into the investigation period). Public-company mergers run 4–8 months from announcement to closing depending on antitrust and regulatory complexity.
What is novation, and why does it matter in federal contractor M&A?
When a federal contract is being transferred from one entity to another (typically in an asset sale or some stock deals), FAR Subpart 42.12 requires a formal novation agreement — a three-way contract between the seller, buyer, and government. Without novation, the government has no obligation to perform under the contract with the new owner. Novation processing typically takes 60–120 days through the contracting officer and is one of the most common closing condition delays in DC M&A.
Do I need separate antitrust counsel in DC?
DC is the antitrust capital of the country — the DOJ Antitrust Division and FTC are both headquartered here. For deals above $200M or in concentrated industries (telecom, defense, healthcare, technology), specialty antitrust counsel is standard. Most DC BigLaw firms have full antitrust groups in-house. Second-request investigations typically add $1M–$3M in legal fees and 4–8 months to the closing timeline.
What's the role of DC counsel in deals with foreign acquirers?
Heavy. Beyond CFIUS, DC counsel handle FOCI (Foreign Ownership, Control, or Influence) mitigation agreements for cleared defense contractors, DDTC ITAR / EAR export-control approvals, and OFAC sanctions screening. These DC-specific regulatory layers often determine whether a deal can close at all, regardless of the commercial terms.
How are reps-and-warranties insurance deals priced in DC?
R&W insurance is standard on most DC private-company M&A above $25M. Premiums typically run 2.5%–4% of the policy limit, with limits typically set at 10% of deal value. Retentions are usually 0.5%–0.75% of deal value. For federal contractor deals, insurers price additional risk around contract-novation issues, security-clearance status, and DCAA audit exposure.
