Rosen Law Firm Urges Tandem Diabetes Care Investors to Investigate Possible Securities Class Action

On January 21, 2026, the Rosen Law Firm, prominent in global investor rights, made a significant announcement regarding Tandem Diabetes Care, Inc. (NASDAQ: TNDM). This firm is currently solidifying its investigations into potential securities claims that affect shareholders due to foresight allegations indicating that Tandem Diabetes Care may have issued misleading business information. As a result, many shareholders could find themselves entitled to compensation, potentially without incurring any fees through a contingency arrangement.

The context behind Rosen's actions stems from the company's announcement on August 7, 2025. On that day, before the market opened, Tandem Diabetes released a communication detailing a voluntary medical device correction affecting specific models of their tslim X2 insulin pumps. The release noted a speaker-related issue that could potentially lead to interruptions in insulin delivery. Following this announcement, Tandem's stock saw a substantial decline, plummeting by 19.9%. This steep drop has raised numerous questions regarding the accuracy and sufficiency of the information provided by the company.

Rosen Law Firm's proactive approach aims to prepare a class action that seeks to recover losses incurred by investors. Those who purchased Tandem stocks during the relevant period are encouraged to consider joining this potential class action. Interested parties can initiate the process by visiting the firm’s dedicated webpage or contacting Phillip Kim, Esq. directly for further details or assistance.

Given the circumstances, the Rosen Law Firm emphasizes the importance of choosing experienced and reputable legal counsel for investors facing securities law issues. The firm has a long track record of success in leading roles in securities class actions, boasting accomplishments such as securing some of the largest settlements for investors. For example, in 2019, the Rosen Law Firm recovered over $438 million for clients. Its founder, Laurence Rosen, was recognized as one of the top lawyers in the Plaintiffs' Bar by Law360, reflecting the firm’s notable proficiency and industry standing.

In light of these developments, shareholders should remain vigilant and informed about their rights. The actions taken by the Rosen Law Firm underline the necessity of accountability from publicly traded companies and highlight the firm's commitment to safeguarding investor interests. By following updates from the firm through their respective social media outlets, investors can stay informed about continuing developments in the Tandem Diabetes case and crucial updates regarding investor rights.
