Uniform Antitrust Pre-Merger Notification Update
HB 1427 updates Colorado’s antitrust pre-merger notification law to align with the Uniform Antitrust Pre-Merger Notification Act approved by the Uniform Law Commission. The bill requires a person filing a pre-merger notification to submit a complete electronic copy of the federal Hart-Scott-Rodino form to the attorney general no later than one business day after filing the notification, and it directs the attorney general to provide a secure means for receiving and storing the submitted materials. It also preserves the attorney general’s ability to review and handle additional documentary material connected to the filing.
The bill strengthens confidentiality and information-sharing rules. It allows the attorney general to share filings with attorneys general in other states only if those states have enacted the same or a substantively equivalent law, have confidentiality protections at least as strong as Colorado’s, and provide assurances that the information will remain confidential. It also requires notice to the filing party before disclosure, extends the notice period to five business days, and directs the attorney general to destroy or return submitted materials within 120 days after the transaction closes or related legal proceedings end, unless another law or court order requires otherwise.
HB 1427 also updates enforcement provisions. The attorney general may seek civil penalties of up to $10,000 per day for noncompliance with the filing requirements, but only after written notice and a three-business-day opportunity to cure. The bill specifies that any penalty must comply with due process requirements. The act takes effect after the standard referendum period unless referred to voters.
The overall sentiment appears favorable and largely noncontroversial. The bill passed the House Judiciary Committee unanimously and passed third reading in both chambers with substantial support, though the Senate Judiciary Committee vote was tied 3-3, suggesting some disagreement at the committee level. The main points of contention likely involved the scope of attorney general authority, the confidentiality and interstate sharing of merger information, and the civil penalty provisions, while supporters likely viewed the bill as a technical update that improves consistency with national uniform law standards and enhances antitrust enforcement.
The bill amends Colorado’s antitrust pre-merger notification statutes in Title 6, article 4.5, by adding a definition of the Uniform Antitrust Pre-Merger Notification Act, tightening filing deadlines, requiring secure electronic submission and storage, expanding reciprocity rules for sharing merger materials with other states, adding a destruction/return timeline for submitted materials, and revising civil penalty and cure provisions. It affects parties engaged in reportable mergers and acquisitions, as well as the Colorado attorney general’s office and, indirectly, other state attorneys general that participate in coordinated antitrust review.
The bill’s reception was generally positive, with strong floor support in both chambers and unanimous support in House Judiciary. The Senate Judiciary Committee was evenly split, indicating some hesitation or disagreement about specific enforcement and confidentiality provisions. Overall, the votes suggest broad agreement that the measure is a technical modernization of merger-notification procedures, tempered by some concern over how the attorney general may collect, retain, and share sensitive transaction information.
The most notable points of contention appear to be the attorney general’s handling of confidential merger materials, the conditions for sharing those materials with other states, and the enforcement mechanism for late or incomplete filings. Opponents or skeptics likely focused on privacy, business confidentiality, and the breadth of state coordination, while supporters emphasized uniformity, secure information handling, and stronger antitrust oversight. The tied Senate Judiciary vote suggests these issues were the primary source of disagreement.
