This bill adopts a uniform state law requiring companies to send federal premerger antitrust filings to the Washington Attorney General under specific conditions, while ensuring confidentiality and allowing limited sharing with other states. It also updates existing state law to align with this new federal filing requirement.

  • Requires companies that file federal premerger (Hart-Scott-Rodino) notifications to also submit the filing (and sometimes supporting documents) to the Washington Attorney General if they meet one of three conditions: (a) their main office is in Washington, (b) they generate at least 20% of the federal filing threshold in Washington sales, or (c) they are a healthcare provider operating in Washington.
  • Mandates that the Attorney General keep all submitted filings and supporting documents confidential—exempt from public records requests—unless disclosure is ordered by a court or agency in a related legal proceeding.
  • Allows the Attorney General to share filings with other states that have similar laws, but only after giving the filer at least two business days’ notice and only if the other state offers comparable confidentiality protections.
  • Authorizes the Attorney General to impose civil penalties of up to $10,000 per day for failure to file or provide required documents, subject to due process.
  • Amends existing Washington law (RCW 19.390.060) to clarify that submitting the federal Hart-Scott-Rodino form to the Attorney General satisfies the state’s prior notice requirement under RCW 19.390.040.

Who is affected

  • Companies and healthcare providers filing premerger notificationsBusinesses or organizations that plan to merge or acquire other entities and file federal premerger notifications (Hart-Scott-Rodino forms) must now also submit those filings—and possibly supporting documents—to the Washington Attorney General if they meet certain thresholds related to Washington operations or sales.
  • Washington Attorney General's OfficeThe Washington Attorney General gains new authority to receive, review, and (under limited conditions) share confidential premerger documents to support antitrust enforcement efforts, but is prohibited from charging fees for this service.
  • Other state attorneys generalOther states that have enacted similar laws may receive premerger filings from Washington, but only after the filer is notified and only if those states offer comparable confidentiality protections.
  • Washington consumersConsumers and the public are indirectly affected if mergers are blocked or modified due to antitrust concerns, as this could influence market competition, prices, and service quality.
Effective: July 1, 2025Fiscal impact: No significant fiscal impact is expected, as the bill prohibits the Attorney General from charging fees for filings and requires use of existing staff and resources to implement the new requirements.

Pro/Con Analysis

Stronger case for benefits

Potential Benefits (5)
  • Expanding filing requirements to include *all* healthcare providers operating in Washington (not just large systems) enhances state oversight of consolidation in critical sectors — this could help prevent monopolistic pricing or reduced access to care in rural or underserved communities.

    HealthcarePeopleRef: Sec. 3(1)(c)
  • Requiring companies with principal place of business in Washington to file state-level notices ensures local antitrust enforcement aligns with state economic interests — this strengthens the state’s ability to challenge mergers that harm Washington-based competition, potentially protecting local jobs and small-business suppliers.

    Business & EmploymentPeopleRef: Sec. 3(1)(a)
  • Allowing reciprocity with other states that have similar laws enables coordinated multistate antitrust enforcement — this increases the state’s leverage in challenging large regional or national mergers without requiring new legislation or inter-state treaties.

    Local GovernmentPeopleRef: Sec. 5
  • Requiring submission of supporting documentary material (e.g., internal emails, market analyses) gives the Attorney General access to evidence that may be critical in evaluating whether a merger harms competition — this improves enforcement quality and deters anti-competitive behavior that could lead to higher prices or reduced service quality.

    Public SafetyLean peopleRef: Sec. 3(2) & (3)
  • The 20% sales threshold ensures that even out-of-state companies with substantial Washington operations (e.g., national pharmacy chains, hospital systems) must notify the state — this helps prevent out-of-state entities from consolidating market share without state review, protecting local healthcare access.

    HealthcarePeopleRef: Sec. 3(1)(b)
Potential Concerns (5)
  • The bill prohibits the Attorney General from charging fees for filing or providing documents, eliminating a potential revenue stream that could have offset implementation costs — though fiscal impact analysis states no significant cost is expected, this removes a minor flexibility for future budgeting.

    Local GovernmentRef: Sec. 3(4)
  • The bill makes all submitted Hart-Scott-Rodino filings and supporting documents exempt from public records requests (RCW 42.56.540), limiting public transparency around corporate mergers that may affect market competition, pricing, and service access — potentially reducing accountability for antitrust enforcement.

    Rights & LibertiesRef: Sec. 4(2)
  • The bill authorizes civil penalties of up to $10,000 per day for noncompliance, which could impose significant financial risk on companies that misinterpret filing thresholds or experience administrative delays — though due process is required, the per-day penalty structure creates exposure for small and mid-sized firms with limited legal resources.

    Business & EmploymentRef: Sec. 6
  • The bill does not restrict the Attorney General from sharing information with federal agencies (FTC, DOJ), but it also does not require coordination or reporting to those agencies — this could lead to duplication of effort or inconsistent enforcement priorities between state and federal antitrust authorities.

    Local GovernmentRef: Sec. 4(4)(c)
  • The 20% of filing threshold sales threshold (currently $200M federal threshold → $40M in WA sales) may disproportionately impact mid-sized regional companies operating across state lines, creating compliance complexity without clear benefit to Washington-specific antitrust concerns — especially since many such firms may have minimal Washington-specific market power.

    Business & EmploymentRef: Sec. 3(1)(b)

Who Is Most Affected

Large national corporations with WA operationsMixed Impact

Large national corporations with Washington operations (e.g., Amazon, Microsoft, national healthcare systems) will face new administrative burden and potential delays in merger timelines, but may benefit from clearer state expectations and reciprocity with other states.

Small and mid-sized Washington-based businessesPositive Impact

Small and mid-sized Washington-based businesses (e.g., regional hospitals, local utilities, independent retailers) gain stronger state-level antitrust protection against acquisition by larger players, potentially preserving local markets and jobs.

Washington Attorney General's OfficePositive Impact

The Attorney General gains new authority to review and share merger intelligence, enhancing state enforcement capacity — though constrained by confidentiality and no-fee rules, this strengthens the state’s role in protecting competitive markets.

Washington consumersPositive Impact

Consumers may benefit from reduced risk of monopolistic pricing or service degradation in healthcare, retail, and other sectors — but the impact depends on how aggressively the AG uses the new authority.

Healthcare providers (small/medium)Mixed Impact

Healthcare providers (especially single clinics or small networks) must now file even if their merger is minor — this adds compliance cost but may prevent harmful consolidation in fragmented care markets.
