Hard Disk Drive Suspension Assemblies Antitrust Litigation

The causation theory is based on the premise that the defendants' conspiracy to fix prices and allocate market shares for HDD suspension assemblies artificially inflated prices. This conspiracy led to overcharges passed through the supply chain to end-users, causing economic damages. Expert analyses, including regression models, support the link between the conspiracy and damages, reinforced by DOJ criminal pleas confirming the illegal conduct.
