Bill Overview

Analyzed Economic Effects

2 provisions identified: 0 benefits, 0 costs, 2 mixed.

Merger privacy protections with limited sharing

Beginning July 27, 2025, Washington’s attorney general cannot publicly disclose covered merger forms, extra documents, or the proposed merger. The fact that materials were submitted is also protected, and these records are exempt from public inspection and copying. Disclosure in a relevant court or agency proceeding requires a protective order. The law preserves specified sharing with federal antitrust agencies. Sharing with another state requires that state to have the uniform act or a substantially equivalent law with equally strong confidentiality protections. Before interstate sharing, the attorney general must give the filer at least two business days’ notice.

New merger filing rules and penalties

The law covers federal premerger notices filed on or after July 27, 2025. Covered filers must send Washington’s attorney general a complete electronic copy of the federal form. This applies to filers based in Washington and health care providers or provider organizations doing business there. It also covers filers whose annual Washington sales meet at least 20% of the federal filing threshold. That sales test includes entities the filer controls and covers the goods or services involved in the deal. Washington-based filers must also submit the extra documents filed with their federal form. Sales-based and provider filers must supply those documents within seven days after the attorney general requests them. The state cannot charge submission fees, and a provider’s submission also satisfies Washington’s separate health care merger notice requirement. For filing or document violations, the attorney general may seek up to $10,000 per day, with due process protections.
