What Changed Recently?
Antigo Construction, Inc. and its related companies, Badger State Highway Equipment, Inc., Antigo International Inc. and Antigo MHB Breakers Ltd., agreed to settle Kubacki v. Antigo Construction, Inc., Case No. 2026CV000035, a class action in the Wisconsin Circuit Court for Langlade County. The court authorized notice to the class, and the settlement website is now taking claims.According to the settlement agreement, the ransomware group DragonForce gained access to the companies’ network between June 1 and June 6, 2025, and claims to have stolen about 104 gigabytes of data. The files potentially contained names, Social Security numbers, driver’s license numbers, financial account numbers and health insurance information belonging to current, former and prospective employees. Antigo discovered the breach on June 6, 2025 and began mailing notices on October 31, 2025. The plaintiff first sued in federal court in Wisconsin in November 2025, then dismissed that case and refiled in Langlade County in March 2026. Antigo denies the claims and any wrongdoing, and the court has not decided who is right.
Who Qualifies?
The settlement class includes every person whose private information was potentially accessed in the data breach. Excluded are Antigo and its parents, subsidiaries, affiliates, officers and directors; anyone who opts out by November 9, 2026; the attorneys for the parties; the judges assigned to the case and their immediate families; and anyone found criminally responsible for the breach.How Much Can You Get?
Each class member who files chooses one of two cash options:- $100 Alternative Cash Payment: a flat payment with no documentation required.
- Documented losses and lost time, up to $3,000 combined: reimbursement of documented, unreimbursed out-of-pocket losses fairly traceable to the breach and incurred from June 1, 2025 through the end of the claims period, plus up to five hours of lost time at $25 an hour ($125 maximum). Eligible losses include credit report and credit freeze fees, card replacement, late and over-limit fees, payday loan interest and fees, bank or credit card fees, postage, mileage and other incidental costs, and credit monitoring or identity-theft insurance bought before the settlement takes effect.
Payments for documented losses and lost time share a $200,000 aggregate cap; if valid claims in those categories exceed it, those payments are reduced pro rata. A loss claim without acceptable documentation may be converted to the $100 payment. Separately, every class member gets two years of three-bureau credit monitoring with no claim form. Antigo pays attorneys’ fees and costs of up to $145,000, a $2,500 service award and all notice and administration costs separately, so those amounts do not reduce class members’ benefits.
What Proof or Notice ID Is Required?
The online claim form opens with the Notice ID printed above the class member’s name and address on the mailed notice, or the Claimant ID on an emailed notice, together with the class member’s last name. The $100 option needs no documentation. The loss option requires documentation for each expense, such as receipts or statements; self-prepared records alone are not enough. Lost time requires an attestation briefly describing what was done.What Is the Deadline?
- November 9, 2026: deadline to opt out or object (postmarked).
- December 14, 2026, 8:30 a.m.: final fairness hearing in the Circuit Court for Langlade County, Wisconsin, or remotely if the court sets it that way.
- December 24, 2026: claim forms due, submitted online or postmarked.
The credit monitoring activation code on the notice must be used within 180 days of the date the notice was mailed, according to the notice.
