Semtech Corporation (NASDAQ: SMTC)

If you have held Semtech shares continuously since at least October 10, 2024, and continue to hold those shares, you may have standing to seek corporate governance reforms at Semtech, including improvements to disclosure practices, product oversight, internal controls, and executive accountability.

Complaint Allegations

A previously filed securities class action complaint alleges that Semtech and certain executives made materially false and misleading statements and/or failed to disclose material adverse facts concerning its CopperEdge products. Specifically, the complaint alleges that the products did not meet the needs of a server rack customer or end users, that certain rack architecture changes were required, and that CopperEdge sales would not ramp up during fiscal 2026 as previously represented. Consequently, sales allegedly would be lower than expected, rendering defendants’ positive statements about the Company’s business and prospects materially misleading and/or without a reasonable basis.

Roblox Corporation (NYSE: RBLX)

If you have held Roblox shares continuously since at least October 30, 2025, and continue to hold those shares, you may have standing to seek corporate governance reforms at Roblox, including improvements to user-safety oversight, disclosure practices, internal controls, and executive accountability.

Complaint Allegations

A previously filed securities class action complaint alleges that Roblox and certain executives made materially false and misleading statements concerning the Company’s commitment to protecting young users and the anticipated business impact of its age-verification rollout. The allegations concern whether defendants adequately disclosed risks to user growth, engagement, and financial performance associated with enhanced age-verification requirements. Subsequent disclosures concerning slowing user growth, friction from the age-check rollout, and reductions to revenue and bookings guidance allegedly revealed the misleading nature of prior statements.

Quantum Corporation (NASDAQ: QMCO)

If you have held Quantum shares continuously since at least November 14, 2024, and continue to hold those shares, you may have standing to seek corporate governance reforms at Quantum, including improvements to revenue-recognition practices, financial reporting, internal controls, and executive oversight.

Complaint Allegations

A previously filed securities class action complaint alleges that Quantum and certain defendants made materially false and misleading statements and/or failed to disclose material adverse facts concerning the Company’s financial reporting. Specifically, the complaint alleges that Quantum improperly recognized revenue during the fiscal year and would need to restate its previously filed third-quarter financial statements. As a result, defendants’ statements concerning the Company’s business, operations, and prospects allegedly were materially false and misleading and/or lacked a reasonable basis.

PROCEPT BioRobotics Corporation (NASDAQ: PRCT)

If you have held PROCEPT BioRobotics shares continuously since at least February 27, 2024, and continue to hold those shares, you may have standing to seek corporate governance reforms at PROCEPT BioRobotics, including improvements to sales practices, customer-inventory monitoring, disclosure controls, and executive oversight.

Complaint Allegations

A previously filed securities class action complaint alleges that PROCEPT BioRobotics and certain executives misled investors concerning sales of the Company’s single-use handpieces for its Aquablation therapy. Specifically, the complaint alleges that PROCEPT used bulk-order discounts to encourage customers to purchase handpieces beyond their procedural needs, pulling sales forward from future periods and artificially inflating reported unit sales and revenues. The complaint further alleges that excess customer inventories undermined future demand and that subsequent disclosures concerning weaker handpiece sales, excess inventory, and the elimination of bulk-purchase discounts revealed the alleged misconduct.
