Park Dental Partners says patients' health data was taken in network breach and faces four class actions

Park Dental Partners, Inc. (Nasdaq: PARK; SEC CIK 2069604) has told the SEC that patients' protected health information was taken in a breach of its computer network, and that four putative class actions have been filed over the incident.

The company first identified unauthorised access to its network on 28 August 2026. It says it engaged external cybersecurity and forensic specialists and notified law enforcement (Form 8-K, Item 1.05, filed 13 October 2026).

The investigation has determined that data was subject to unauthorised acquisition. The company says it has identified impacted patients whose protected health information was involved and is completing notifications under state and federal law (Form 8-K, 13 October 2026).

The four lawsuits were filed in the Second Judicial District, Ramsey County, Minnesota, the first on 3 September 2026. All allege failure to safeguard protected health information, failure to implement reasonable security and failure to notify in time. On 7 October 2026 the plaintiffs moved to consolidate the cases and appoint interim lead class counsel. The company says it intends to defend its positions vigorously (Form 8-K, 13 October 2026).

The filing says that, to date, the company has not identified any material impact on its financial condition or results of operations, and is not aware of any unauthorised use of protected health information or any damages. It says it anticipates regulatory responses (Form 8-K, 13 October 2026).

The filings do not state how many patients were affected, how the access occurred or who was responsible. Loro has made no approach to the company. Figures are as reported in Park Dental Partners' SEC filings.
