Alger Weatherbie Specialized Growth Fund stated the following regarding Tandem Diabetes Care, Inc. (NASDAQ:TNDM) in its Q4 2024 investor letter:

“Tandem Diabetes Care, Inc. (NASDAQ:TNDM) designs and manufactures innovative insulin delivery systems for people with diabetes. The company’s flagship product, the t:slim X2 insulin pump, integrates advanced technology for precise insulin management, including features like continuous glucose monitoring (CGM) compatibility and remote software updates. During the quarter, the company reported strong fiscal third-quarter results, with revenue beating analyst estimates and accelerating to 25% year-over-year, driven by strong renewal rates, the U.S. launch of the Mobi pump boosting new customer starts, and international growth. However, shares detracted from performance as investor sentiment was impacted by management’s lack of formal 2025 guidance, instead offering preliminary commentary focused on predictable revenue streams and gradual growth from new opportunities. While the company highlighted progress with Mobi adoption, renewal rates, and new sensor integrations, concerns lingered about the timeline and execution of key product launches, such as the t:slim X3 pump and the Sigi patch pump, as well as uncertainties around the pace of market expansion and margin improvements. In our view, the company has a number of margin accretive new products recently launched—or soon to launch—as well as efficiency initiatives underway, and believe these near-term profitability concerns appear to be overblown.”
