Lead Plaintiff Motion DeadlineApril 07, 2025

On October 30, 2024, Monolithic released its third quarter 2024 financial results, disclosing that its Enterprise Data revenue had declined sequentially during the quarter to $184 million, missing consensus estimates by nearly 13%. The Company further revealed that customer order patterns had fallen materially below recent historical trends, which was expected to continue.

On this news, Monolithic’s stock price fell $160.51, or 17.5%, to close at $759.30 per share on October 31, 2024, thereby injuring investors.

Then, on November 11, 2024, Edgewater Research published a report revealing that Nvidia had canceled half of its outstanding Monolithic orders and would be eliminating Monolithic as a supplier due to persistent “[p]erformance issues” with the Company’s power modules.

On this news, Monolithic’s stock price fell $113.99, or 14.97%, to close at $647.31 per share on November 11, 2024, thereby injuring investors further.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors: (1) that Monolithic’s voltage regulator modules and power management integrated circuits were suffering from significant performance and quality control issues; (2) that the defects had, in turn, negatively impacted the performance of certain products offered by Nvidia in which such products were used; (3) that Monolithic had failed to adequately address and resolve known issues affecting the performance of the power management solutions the Company supplied to Nvidia; (4) that Monolithic’s relationship with Nvidia – the Company’s most important customer – had been irreparably damaged due to the significant performance and quality control problems affecting the products it supplied to Nvidia and the Company’s failure to adequately address such issues; and (5) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
