Fourth Quarter and Full Year 2024 Sales Results Compared to 2023

From September 2022 through February 2024, the Company offered the Tandem Choice Program (Tandem Choice) to eligible t:slim X2 customers to provide a pathway to ownership of Tandem Mobi, for a fee when available.

As a result of this program, the Company is providing select financial results on both a GAAP and non-GAAP basis. Additional information, including the accounting treatment of this program and other non-GAAP measures, can be found under Table D “Reconciliation of GAAP versus Non-GAAP Financial Results” attached to this press release.

2025 Financial Guidance

“We are committed to delivering sustained profitable growth and are funding key commercial investments while driving operating leverage,” said Leigh Vosseller, executive vice president and chief financial officer. “These investments focus on our U.S. sales infrastructure, business systems and technology, as well as the establishment of operations to support a direct launch in select European countries and are fundamental to achieving our longer-term financial objectives.”

For the year ending December 31, 2025, 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 $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.
• Sales for the first quarter are estimated to be approximately $219 million to $224 million.
  • Sales in the United States of approximately $144 million to $147 million.
  • Sales outside the United States of approximately $75 million to $77 million.
• Gross margin is estimated to be approximately 54 percent for the full year and approximately 51 percent for the first quarter.
• Adjusted EBITDA margin⁽¹⁾ is estimated to be approximately 3 percent for the full year and negative 6 percent for the first quarter.
• 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 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.

The accounting treatment for Tandem Choice had 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. When a customer elected to participate in Tandem Choice, the Company recognized 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 was based on either a) an affirmative election to participate in Tandem Choice or b) expiration of the right to participate at program expiration, provided all obligation under the Tandem Choice program were satisfied.

Notably:

• Offering the program did not impact the economics associated with how or when the initial pump sale is reimbursed.
• Customer eligibility for Tandem Choice was automatic at the time of a t:slim X2 purchase. Customer eligibility ended in February 2024 with the commercial availability of Tandem Mobi.
• Qualifying customers were able to elect participation in Tandem Choice starting at the end of the second quarter of 2024.
• An affirmative election was required for the customer to participate in Tandem Choice, at which time any customer fees were received and recognized as a sale. The Tandem Choice program expired on December 31, 2024.

Although the Tandem Choice program has ended, non-GAAP sales are presented in this press release for consistency with the Company’s historical presentation of non-GAAP sales in its earnings releases since the launch of Tandem Choice and as a comparison to the Company’s previously provided non-GAAP sales guidance for the year ended December 31, 2024.
