2025 Financial Guidance

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

Sales for the full year are estimated to be approximately $997 million to $1.007 billion.
- Sales in the United States of approximately $725 million to $730 million.
- Sales outside the United States of approximately $272 million to $277 million, which reflects a $15 million to $20 million headwind associated with the Company’s preparation for direct commercial operations in select countries.
Gross margin is estimated to be approximately 54% of sales for the full year.
Adjusted EBITDA margin⁽¹⁾ is estimated to be approximately 3% of sales for the full year.
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, they will be calculated using a consistent method from period to period. 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.

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.
