PSIX Investors Urged to Seek Lead Role in Newly Filed Securities Case

Overview

• The Rosen Law Firm and The Gross Law Firm issued notices inviting PSIX shareholders to contact them about serving as lead plaintiff and say clients owe no upfront fees under contingency terms.
• A securities class action has been filed against Power Solutions International that claims the company misled investors about data‑center sales prospects and the costs and inefficiencies tied to factory upgrades.
• The proposed class covers people who bought Power Solutions shares from May 8, 2025 through March 2, 2026.
• Investors who want to lead the case must ask the court to be appointed by May 19, 2026, a role that helps direct the lawsuit on behalf of the class.
• No class has been certified, which means investors are not represented unless they retain a lawyer.
