When a Seattle business needs an M&A lawyer
Most Seattle M&A engagements start in one of four places. A strategic acquirer (often Amazon, Microsoft, Salesforce, or Adobe) circulates a term sheet for a tuck-in. A growth equity sponsor approaches a Series C or D SaaS founder about a recap or sale. A multi-generational consumer brand prepares for an estate-driven sale. An aerospace or supply chain operator looks to consolidate around a Tier 1 or Tier 2 Boeing supplier. The Seattle corporate bar has substantial bench depth in all four scenarios.
Perkins Coie (Seattle-headquartered), Davis Wright Tremaine (Seattle-headquartered), K&L Gates (substantial Seattle office), and Wilson Sonsini (significant Seattle presence) anchor the senior end of the market. National firms with growing Seattle offices include Cooley, Latham, Sidley, Kirkland, and DLA Piper. Mid-market and boutique firms — Lasher Holzapfel, Ryan Swanson, Lane Powell, Foster Garvey, Stoel Rives — handle middle-market and founder-led work.
Seattle-specific deal mechanics:
- Cap table cleanup for venture-backed targets (option pool true-ups, preferred stock conversions)
- IP assignment diligence (founder IP assignments, open-source license review, AI training data provenance)
- Washington Business Corporation Act (Title 23B RCW) for WA-formed corporate targets
- Washington non-compete enforceability under RCW 49.62 (income-threshold restriction)
- Washington 7% capital gains tax planning for founder-sellers above $250K threshold
- CFIUS review for foreign acquirers of US tech, AI, semiconductors, or sensitive personal data
- FTC and DOJ Antitrust scrutiny on big-tech strategic acquisitions
- Microsoft's MSFT-specific acquisition standard documents and stock-as-consideration mechanics
- R&W insurance routinely used to reduce or eliminate seller indemnity escrow

Seattle M&A Lawyers — FAQ
How much do M&A lawyers cost in Seattle?
Seattle BigLaw M&A partners bill $795–$1,650/hr; senior associates $525–$1,150/hr. Seattle-headquartered firms like Perkins Coie and Davis Wright Tremaine run $725–$1,450/hr at the partner level. Mid-market and boutique Seattle firms run $395–$725/hr. Typical legal fees for a $25M–$100M deal: $200,000–$575,000. A $250M–$1B deal routinely runs $1.5M–$6M in legal fees.
What industries dominate Seattle M&A?
Technology. Seattle is dominated by Amazon's cloud ecosystem, Microsoft's enterprise software acquisitions, gaming (Valve, Bungie, ArenaNet, Nintendo of America in Redmond), aerospace and aerospace supply chain (Boeing-area), life sciences (Fred Hutch, UW spinouts), seafood and food processing, and a large consumer brand cluster (Starbucks, Costco, Nordstrom, REI). M&A counsel in Seattle routinely handle cloud-era SaaS deals, marketplace acquisitions, biotech licensing-and-acquisition, and aerospace supply chain consolidation.
How long does a Seattle M&A deal take to close?
A typical private middle-market deal in Seattle runs 75–135 days from LOI to closing. Tech deals are often faster because the diligence is lighter (clean cap tables, modern cloud infrastructure, fewer physical assets) — sometimes closing 60–90 days from signed LOI. HSR adds 30 days. CFIUS adds 45–90 days for deals involving foreign acquirers of US tech, particularly AI, semiconductors, or sensitive personal data.
What's the role of Washington state law in Seattle M&A?
Most acquisition agreements are governed by Delaware law even when both parties are Washington-formed. Washington Business Corporation Act (Title 23B RCW) and Washington Limited Liability Company Act (Chapter 25.15 RCW) apply to corporate housekeeping of WA-formed targets. Washington's non-compete reform (RCW 49.62) is stricter than most states — employee non-competes are only enforceable above an income threshold ($120,559 in 2024, indexed annually), and sale-of-business non-competes have their own rules.
What about Washington-specific tax issues?
Washington has no personal income tax, so seller individual planning revolves around federal capital gains, QSBS exclusions under Section 1202, and rollover equity structuring. Washington's Business & Occupation (B&O) tax applies at the entity level and can affect asset-deal structuring. The 7% Washington capital gains tax on individual gains above $250,000 (enacted 2021, upheld 2023) is a recent addition that Seattle M&A counsel routinely plan around for founder-seller liquidity events.
How does CFIUS affect Seattle tech deals?
Significantly. The Committee on Foreign Investment in the United States reviews foreign acquisitions of US businesses involving sensitive tech, critical infrastructure, or sensitive personal data. Seattle's concentration of AI, cloud, semiconductor, biotech, and aerospace companies means CFIUS is routinely on the radar for inbound Chinese, Saudi, UAE, and other foreign acquirers. Mandatory declaration thresholds under FIRRMA apply to many Seattle tech targets.
How active is private equity in Seattle M&A?
Growing. Seattle hosts Madrona Venture Group, Voyager Capital, Trilogy Equity Partners, Endeavour Capital, and a growing cluster of growth equity and middle-market PE sponsors. Traditional Seattle deal flow has tilted toward strategic acquirers (Amazon, Microsoft, Salesforce buying smaller tech), but the city has seen substantial growth in PE-backed buyouts in business services, healthcare, and consumer brands over the past five years.
Do I need separate antitrust counsel for tech deals?
For most middle-market tech deals, your M&A firm handles HSR filing in-house. The big tech antitrust focus from DOJ and FTC means the largest Seattle deals — Microsoft's billion-dollar acquisitions, Amazon's strategic deals — get specialty antitrust counsel automatically. For middle-market deals above $200M in concentrated tech subsegments (cloud infrastructure, marketplaces, ad-tech), specialty antitrust counsel adds material value.
