Rosen Law Firm Investigates Tandem Diabetes Care for Potential Securities Fraud

The Rosen Law Firm, an esteemed global investor rights law firm, has initiated an investigation regarding possible securities claims on behalf of shareholders of Tandem Diabetes Care, Inc. (NASDAQ: TNDM). This investigation comes in the wake of allegations that Tandem Diabetes Care may have provided materially misleading information about its business operations to the investing public.

This inquiry is particularly important for investors who may have suffered losses due to the company’s actions. If you had purchased Tandem Diabetes Care securities, you might be eligible for compensation without needing to pay any out-of-pocket fees, thanks to a contingency fee arrangement. The Rosen Law Firm is taking steps to prepare a class action lawsuit aimed at recovering investor losses, which could potentially benefit many shareholders affected by this situation.

What You Need to Know

On August 7, 2025, just before markets opened, Tandem Diabetes Care issued a press release titled "Tandem Diabetes Care Issues Voluntary Medical Device Correction for Select tslim X2 Insulin Pumps." In this release, the company announced a voluntary medical device correction for specific tslim X2 insulin pumps after identifying a potential speaker-related issue that could result in the cessation of insulin delivery, which is critically important for users of the device.

Following this announcement, the company's stock price plummeted by 19.9% on the same day, causing significant concern among investors about the company’s transparency and the potential impact on their investments. This sharp decline emphasized the need for an in-depth investigation into whether Tandem Diabetes had indeed misled investors regarding the reliability of its products.

The Strong Case for Investors

The Rosen Law Firm highlights the importance of engaging qualified legal counsel when it comes to securities class action cases. It is essential for investors to choose law firms that possess a proven history of success and leadership in such litigations. Many firms that issue notices do not have comparable experience or the requisite resources, which can be detrimental to investors. The Rosen Law Firm emphasizes that several litigation firms do not actively engage in securities class actions, making it imperative for shareholders to select their legal representation wisely.

With a proven track record, the Rosen Law Firm has represented investors across the globe, focusing specifically on securities class actions and shareholder derivative litigation. Noteworthy accomplishments include securing the largest-ever settlement in a securities class action against a Chinese company at one time. The firm has also consistently ranked among the top in the number of securities class action settlements, with impressive recoveries amounting to hundreds of millions of dollars for investors over the years.

In a particularly impressive year, the Rosen Law Firm secured over $438 million for its clients in 2019 alone, demonstrating its capacity to advocate for and achieve meaningful outcomes for investors. Laurence Rosen, the founding partner, was recognized by Law360 as a 'Titan of Plaintiffs' Bar' in 2020, reflecting the firm's significant stature in the legal community. Furthermore, many of the firm’s attorneys have received accolades from reputable legal publications such as Lawdragon and Super Lawyers.
