2024 Financial Guidance

The Company's non-GAAP guidance for the fiscal year ending December 31, 2024 is set forth below. The most directly comparable GAAP financial measures are not accessible on a forward-looking basis due to the high degree of complexity in the accounting treatment for the Tandem Choice program. For a description of non-GAAP sales, non-GAAP gross margin, and Adjusted EBITDA margin, as well as an illustration of the reconciliation from the most directly comparable GAAP financial measures, refer to Table E "Reconciliation of GAAP versus Non-GAAP Financial Results" attached to this press release. Also see "Non-GAAP Financial Measures" below for additional information.

For the year ending December 31, 2024, the Company is updating its 2024 financial guidance as follows:

• Non-GAAP sales are estimated to be approximately $868 million for the full year and $205 million in the second quarter.
  • Sales in the United States of approximately $634 million for the full year and $150 million in the second quarter.
  • Sales outside the United States of approximately $234 million for the full year and $55 million in the second quarter.
• Non-GAAP gross margin is estimated to be approximately 51 percent for the full year and approximately and 50 percent in the second quarter.
• Adjusted EBITDA margin is estimated to be breakeven as a percent of sales for the full year and approximately negative 5 percent in the second quarter.
• Non-cash charges included in cost of goods sold and operating expenses are estimated to be approximately $120 million. This includes:
  • Approximately $100 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 E "Reconciliation of GAAP versus Non-GAAP Financial Results" attached to this press release.

The Company has not provided a reconciliation of forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures in reliance on the "unreasonable efforts" exception set forth in the applicable regulations, because there is substantial uncertainty associated with predicting any future adjustments that may be made to the Company's GAAP financial measures in calculating the non-GAAP financial measures.

In particular, the accounting treatment for Tandem Choice has a high degree of complexity. In September 2022 when the program was launched, the Company began deferring a portion of sales for each eligible t:slim X2 pump shipped in the United States. The total Tandem Choice deferral was $31.5 million as of March 31, 2024. If a customer elects to participate in Tandem Choice, the Company will recognize the existing deferral, incremental fees received and the associated costs of providing the new insulin pump at the time of fulfillment. The timing of recognition will be based on either a) an affirmative election to participate in Tandem Choice or b) expiration of the right to participate at program expiration.

Notably:

• Offering the program does not impact the economics associated with how or when the initial pump sale is reimbursed.
• Customer eligibility was automatic and no election was necessary to participate in Tandem Choice at the time of a t:slim X2 purchase. Customer eligibility ended in February 2024 with the commercial availability of the new hardware platform, Tandem Mobi.
• An affirmative election is required for the customer to participate in Tandem Choice, at which time any customer fees will be received and recognized as a sale. Any remaining deferrals will be recognized at program expiration.
• The expiration date of Tandem Choice is December 31, 2024.
