2026 Financial Guidance
“In 2026, our goal is to expand the worldwide market by delivering double-digit pump shipment growth. We are adopting a pay-as-you-go model in the U.S. that provides affordable access to customers, and progresses our business toward more predictable and profitable revenue that may not be evident in our 2026 sales expectations,” said Leigh Vosseller, executive vice president and chief financial officer. “We remain committed to improving margins and profitability during this transition that positions Tandem for accelerated sales growth in 2027 and beyond.”
For the year ending December 31, 2026, the Company is providing its full year and first quarter GAAP financial guidance as follows:
- Sales for the full year are estimated to be approximately $1.065 billion to $1.085 billion
- United States - reflects transition to pay-as-you-go business model in pharmacy channel
- Shipments are estimated to increase approximately 10% to 11%
- Sales of approximately $730 million to $745 million
- Pay-as-you-go headwind of approximately $70 million to $80 million
- International - reflects preparation for transition to direct commercial operations in select countries
- Sales of approximately $335 million to $340 million
- Direct transition headwind of approximately $15 million
- Gross margin is estimated to be approximately 56% to 57% of sales

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 acquired in-process research and development (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.
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 did not impact any financial measures for the year ending December 31, 2025.
