Ace Hardware hit with nationwide price-fixing lawsuit alleging consumers overpaid
Plaintiffs claim the alleged scheme drove up prices on essential home repair and household products for millions of consumers
Retail giant Ace Hardware has been accused in a sweeping federal antitrust lawsuit of operating what plaintiffs describe as an illegal nationwide price-fixing scheme that allegedly inflated prices for consumers shopping at thousands of Ace-affiliated stores.
The proposed class action, filed in the U.S. District Court for the Northern District of Illinois, claims Ace and its member stores coordinated retail pricing and imposed restrictions on store locations in ways that violated federal antitrust law.
According to the complaint, pricing at nearby Ace stores often moved “in lockstep,” effectively eliminating the competitive pressure that consumers would normally expect between independently owned retailers.
The lawsuit was brought by Illinois resident Sean Twomey on behalf of an estimated 5 million-plus consumers who allegedly purchased goods from Ace stores since 2022.
Allegations focus on pricing software and shared sales data
The complaint alleges Ace and Texas-based software provider Epicor collected and shared detailed pricing and sales information from member stores through point-of-sale systems and internal reporting tools.
Plaintiffs claim the shared data allowed Ace and participating stores to coordinate pricing strategies instead of competing against one another.
The lawsuit argues the alleged system helped “boost margins and present a more consistent pricing image to consumers,” while reducing price competition on items ranging from tools and hardware supplies to household essentials.
The suit also claims Ace restricted where affiliated stores could operate, preventing new locations from opening too close to existing stores and thereby limiting local competition.
Consumer impact could be significant
If the allegations are proven, the case could have broad implications for consumers already struggling with elevated prices for home maintenance and repair products.
Hardware costs have remained stubbornly high in recent years as inflation, supply-chain disruptions, tariffs, and housing-related demand pushed up prices for building materials and home improvement goods.
Consumer advocates have increasingly warned that some companies may be using data-sharing systems and pricing software to maintain higher prices across markets. Federal regulators, including the U.S. Department of Justice and the Federal Trade Commission, have stepped up scrutiny of algorithmic pricing and information-sharing arrangements in several industries.
The Ace lawsuit echoes other recent antitrust cases targeting companies accused of using shared pricing systems to soften competition while preserving the appearance of independent ownership.
Ace says it is a cooperative of local owners
Founded in 1924, Ace Hardware operates as a retailer-owned cooperative made up of thousands of locally owned stores across the United States. The company reported a record $10 billion in revenue for 2025, according to the lawsuit.
Plaintiffs argue, however, that the cooperative structure has evolved into what they characterize as an “illegal cartel” dominated by large multi-store operators, private-equity-backed ownership groups, and Ace itself.
Ace and Epicor had not publicly responded to the allegations as of Thursday afternoon.
The lawsuit seeks unspecified monetary damages and a court order blocking the alleged pricing practices.
Data Box: What consumers should know
Case: Sean Twomey v. Ace Hardware Corp. et al.
Court: U.S. District Court, Northern District of Illinois
Filed: May 2026
Main allegation: Coordinated pricing and anti-competitive store restrictions
Potential class: Consumers who bought goods from Ace stores since 2022
Defendants: Ace Hardware, affiliated entities, and Epicor
What happens next
The case is still in its early stages, and the allegations have not been proven in court.
If the lawsuit survives early dismissal efforts, plaintiffs will likely seek internal pricing records, communications, and software data that could shed light on how Ace stores set prices nationwide.
Antitrust experts say cases involving cooperative retailers and pricing software can become closely watched tests of how courts interpret competition laws in the era of large-scale retail data sharing.
