Washington's House Bill 2548 is now law — and as of June 11, 2026, any private equity firm, commercial insurer, or hospital looking to acquire a Washington healthcare organization needs to tell the state's Attorney General about it first, before the deal closes.
Governor Bob Ferguson signed HB 2548 on March 25, 2026. It expands the state's existing health care transaction review law to cover a category of buyers that were previously exempt: private equity firms and commercial health insurers. The effective date was June 11 — five days ago. That means any deal in the pipeline right now is subject to these new disclosure requirements.
What the Law Actually Requires
Health care entities — hospitals, hospital systems, and provider organizations — must notify the Washington AG before completing any transaction that involves a change in majority ownership or control, a transfer of a majority of assets (including real property sale-leasebacks), or a conversion from nonprofit to for-profit status.
The new element: the buyer must also disclose "the name of any person or entity with a majority ownership, investment, or controlling interest" — which is how private equity firms and commercial insurers get pulled into the net. Before HB 2548, those buyers could participate in healthcare acquisitions without the same transparency requirements that applied to other acquirers.
Filing fees are tiered based on transaction size: $2,500 for deals under $1 million, scaling up to $25,000 for transactions exceeding $20 million. Parties who complete a transaction must submit outcome notices within 30 days after closing. The AG must publish quarterly summaries of pending and completed transactions online, creating a public record that didn't exist before.
Who owns your hospital matters more than most nurses realize. I've watched systems get acquired, and within 18 months the staffing model changes, the contract structure changes, agency reliance goes up, and full-time positions disappear. Private equity doesn't buy hospitals to improve bedside ratios — they buy to extract margin. Washington just made it slightly harder to do that in the dark. It won't stop every bad deal, but at least there's now a public record of who bought what and when. That's something nurses and their unions can use.
Why This Matters for Nurses Specifically
The legislation was directly informed by reporting that documented increased consolidation, vertical integration, and private equity-backed acquisitions across Washington's healthcare sector. Persistent challenges in assessing market-wide impacts on cost, access, and competition were cited in the bill's legislative record.
For nurses, private equity ownership has historically been associated with increased use of temporary and agency staff — which drives per diem costs but reduces full-time benefits — faster management turnover, and staffing decisions driven by quarterly financial targets rather than patient acuity. Washington already has one of the strongest nursing union environments in the country through WSNA. The new transparency requirement gives the union and regulators advance notice of deals before workers are affected.
The quarterly publication requirement is the practical enforcement mechanism. Any nurse in Washington can now track healthcare acquisitions happening in their market, which is useful context when evaluating the stability of a prospective employer or when negotiating contracts.
What Washington Nurses Can Do Now
If you work at a hospital in Washington and hear rumors of a pending acquisition or ownership change, check the Washington AG's website for disclosure filings. The AG is required to publish quarterly summaries of pending and completed transactions. WSNA and other labor organizations are well-positioned to monitor these filings and respond before deals close rather than after they've already restructured your unit staffing model. Use the public record — that's what it's there for.
Other States Watching
Washington isn't alone. Federal legislation targeting private equity's role in hospitals and nursing homes has been introduced in Congress, though it remains in committee. Several states have enacted or proposed their own healthcare transaction review laws over the past two years, with varying scope and notification timelines. If your state hasn't acted, the Washington model is one template advocates are already pointing to.
