(1) Constant currency sales growth is a non-GAAP measure that represents the change in sales between current and prior year periods using the exchange rate in effect during the applicable prior year period. The Company presents constant currency growth because management believes it provides meaningful information regarding the Company's results on a consistent and comparable basis. The Company uses this non-GAAP measure to evaluate operating results. A reconciliation of constant currency to GAAP sales can be found in Table C "Sales by Geography and Non-GAAP Reconciliation of Constant Currency Sales Growth" attached to this press release. Also see "Non-GAAP Financial Measures" below for additional information.

(2) A reconciliation of non-GAAP financial measures to their most directly comparable GAAP financial measures and additional information can be found in Table D "Reconciliation of GAAP versus Non-GAAP Financial Results" attached to this press release. Also see "Non-GAAP Financial Measures" below for additional information.

See tables for additional financial information.

2026 Financial Guidance

For the year ending December 31, 2026, the Company is reaffirming its financial guidance as follows:

• Sales are estimated to be approximately $1.065 billion to $1.085 billion
  • United States sales of approximately $730 million to $745 million
  • International sales of approximately $335 million to $340 million
• Gross margin is estimated to be approximately 56% to 57% of sales
• Adjusted EBITDA⁽³⁾ margin is estimated to be approximately 5% to 6% of sales
• Non-cash charges included in cost of goods sold and operating expenses are estimated to be approximately $100 million. This includes:
  • Approximately $80 million non-cash, stock-based compensation expense
  • Approximately $20 million depreciation and amortization expense

For a comprehensive overview of the Company's guidance assumptions for 2026, including pricing and transition assumptions for the adoption of pay-as-you go reimbursement in the United States and the initiation of international direct operations, please see the Events & Presentations tab in the Investor Center of the Tandem Diabetes Care website at https://investor.tandemdiabetes.com.

(3) Adjusted EBITDA margin is a non-GAAP financial measure. The Company has not reconciled adjusted EBITDA margin outlook to the most comparable GAAP outlook because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot reasonably be predicted with the level of precision required, the Company is unable to provide outlook for the comparable GAAP measure (net income (loss) as a percentage of sales). Forward-looking estimates of adjusted EBITDA margin are made in a manner consistent with relevant calculations and assumptions noted herein.

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 either exclude items that are unrelated to, and may not be indicative of, the Company's core operating results, or aid in presenting information on a consistent and comparable basis. 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 C "Sales by Geography and Non-GAAP Reconciliation of Constant Currency Sales Growth" and 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 IPR&D expense in its non-GAAP financials. 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.
