2025 Financial Guidance

“We expect to reach $1 billion in worldwide 2025 sales, which is a significant milestone for our company,” said Leigh Vosseller, executive vice president and chief financial officer. “Our narrowed guidance reflects insights gained in the first half of the year, including our U.S. growth expectations as we progress our commercial transformation, increased benefit from accelerated pharmacy channel initiatives and greater contributions from international sales."

For the year ending December 31, 2025, the Company is providing its 2025 financial guidance as follows:

Sales for the full year are estimated to be approximately $1.0 billion.
- Sales in the United States of approximately $700 million.
- Sales outside the United States of approximately $300 million, which reflects a $10 million headwind associated with the Company’s preparation for direct commercial operations in select countries.
Gross margin is estimated to be approximately 53% to 54% of sales for the full year.
Adjusted EBITDA margin⁽¹⁾ is being recast from approximately 3% to approximately negative 5% of sales for the full year, which has been updated to include a negative 8 percentage point impact for an acquired in-process research and development (“IPR&D”) charge that occurred in the first quarter of 2025. Beginning in the second quarter of 2025, the Company no longer included an adjustment for IPR&D expense in its Non-GAAP results to align with views expressed by the staff of the U.S. Securities and Exchange Commission.
Non-cash charges included in cost of goods sold and operating expenses are estimated to be approximately $115 million. This includes:
- Approximately $95 million non-cash, stock-based compensation expense.
- Approximately $20 million depreciation and amortization expense.

Non-GAAP Financial Measures

Certain non-GAAP financial measures are presented in this press release to provide information that may assist investors in understanding the Company’s financial results and assessing its prospects for future performance. The Company believes these non-GAAP financial measures are important operating performance indicators because they exclude items that are unrelated to, and may not be indicative of, the Company’s core operating results. These non-GAAP financial measures, as calculated, may not necessarily be comparable to similarly titled measures of other companies and may not be appropriate measures for comparing the performance of other companies relative to the Company. These non-GAAP financial results are not intended to represent, and should not be considered to be more meaningful measures than, or alternatives to, measures of operating performance as determined in accordance with GAAP. To the extent the Company uses such non-GAAP financial measures in the future, we expect they will be calculated using a consistent method from period to period and, if not, an explanation will be provided. A reconciliation of each of the historical GAAP financial measures to the most directly comparable historical non-GAAP financial measures has been provided in Table D “Reconciliation of GAAP versus Non-GAAP Financial Results” attached to this press release.

In the first quarter of 2025, the Company included an adjustment for IPR&D expense in its non-GAAP financials and provided guidance based on this practice. Beginning in the second quarter of 2025, the Company no longer included an adjustment for IPR&D expense in its non-GAAP results to align with views expressed by the staff of the U.S. Securities and Exchange Commission and 2025 results. The Company’s guidance has been revised accordingly.

The accounting treatment for Tandem Choice, which was in effect from September 2022 through December 2024, had a high degree of complexity. When the program originally launched, the Company began deferring a portion of sales for each eligible t:slim X2 pump shipped in the United States. When a customer elected to participate in Tandem Choice upon the launch of Tandem Mobi in 2024, the Company recognized the existing deferral, incremental fees received and the associated costs of providing the new insulin pump at the time of fulfillment. Historical non-GAAP financial measures are presented in this press release to facilitate better comparisons of the Company’s operating results across the reporting periods. Tandem Choice will not impact any financial measures for the year ending December 31, 2025.

The Company will hold a conference call and simultaneous webcast today at 4:30pm Eastern Time (1:30pm Pacific Time).
