The Signature Performance class action settlement received preliminary approval from the court on January 6, 2026 and covers all living individuals who received notice from Signature that their private information may have been impacted by the January 2024 data breach. Court documents estimate that approximately 232,315 individuals are covered by the settlement.

The court-approved website for the Signature Performance data breach settlement can be found at SignatureDataBreachSettlement.com.

According to the website, Signature Performance settlement class members who file a valid, timely claim form have multiple options for reimbursement.

The deal states that class members who submit with their claim form proof of documented losses related to the data breach are eligible to receive a one-time cash payment of up to $5,000, also called “Cash Payment A” on all court documents. According to the settlement agreement, reimbursable expenses must have been incurred on or after January 17, 2024 and include those related to credit monitoring, credit reports, credit freezes, bank fees and unauthorized card transactions.

Class members seeking a documented-loss payment may not receive reimbursement for losses that have already been reimbursed by another source, including the medical data and credit monitoring services provided by Signature Performance detailed in the data breach notification letter.

In addition to, or in lieu of a documented-loss payment, Signature Performance settlement class members may also file a claim to receive an alternative cash payment of approximately $200 called “Cash Payment B” in court documents. According to the settlement agreement, no proof is required from class members to claim this payout, which may be subject to a pro-rated increase or decrease in value depending on the total number of valid claims filed.

Settlement class members who were California residents at the time of the breach may file a claim to receive, in addition to Cash Payment A and/or Cash Payment B, a one-time cash payment of approximately $200 due to state-specific statutory requirements. Similarly, the settlement site reports that the final amount of the statutory cash payment will depend on the total number of valid claims filed.

Signature Performance class members may elect to receive their cash payouts by check or electronic payment upon submission of their claim form, and the agreement stipulates that all checks must be cashed within 180 days of issuance before expiration.

In addition to any monetary benefits, the agreement states that all class members may also file a claim to receive an enrollment code for three free years of Medical Data Monitoring, which provides services such as medical identity monitoring, credit monitoring, real-time alerts and identity theft insurance.  

Finally, Signature Performance has agreed to implement additional data security measures to ensure private information stored on its systems is protected from future data incidents.

All Signature Performance data breach claim forms must be submitted online or by mail by May 7, 2026.

The court will determine whether to grant final approval to the Signature Performance settlement at a hearing on April 21, 2026. Compensation will begin to be distributed to class members only after final approval has been granted and any appeals have been resolved.

The Signature Performance class action lawsuit alleged that the healthcare administration company did not implement proper cybersecurity measures to protect the sensitive information of healthcare clients’ patients and employees, which led to a data breach sometime between January 17 and 18, 2024. Per court documents, the information that may have been impacted by the breach included names, addresses, phone numbers, dates of birth, Social Security numbers, provider names, medical history, driver’s license and state ID numbers, health insurance information and treatment costs.
