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,\u201d said Leigh Vosseller, executive vice president and chief financial officer. \u201cWe remain committed to improving margins and profitability during this transition that positions Tandem for accelerated sales growth in 2027 and beyond.\u201d<\/p>\n \nFor the year ending December 31, 2026, the Company is providing its full year and first quarter GAAP financial guidance as follows:<\/p>\n \n- \nSales for the full year are estimated to be approximately $1.065 billion to $1.085 billion<\/p>\n<\/li>\n<\/ul>\n
\n- \nUnited States – reflects transition to pay-as-you-go business model in pharmacy channel<\/p>\n<\/li>\n<\/ul>\n
\n- \nShipments are estimated to increase approximately 10% to 11%<\/p>\n<\/li>\n<\/ul>\n
\n- \nSales of approximately $730 million to $745 million<\/p>\n<\/li>\n<\/ul>\n
\n- \nPay-as-you-go headwind of approximately $70 million to $80 million<\/p>\n<\/li>\n<\/ul>\n
\n- \nInternational – reflects preparation for transition to direct commercial operations in select countries<\/p>\n<\/li>\n<\/ul>\n
\n- \nSales of approximately $335 million to $340 million<\/p>\n<\/li>\n<\/ul>\n
\n- \nDirect transition headwind of approximately $15 million<\/p>\n<\/li>\n<\/ul>\n
\n- \nGross margin is estimated to be approximately 56% to 57% of sales<\/p>\n<\/li>\n<\/ul>\n
\n- \nAdjusted EBITDA(2)<\/sup> margin is estimated to be approximately 5% to 6% of sales<\/p>\n<\/li>\n<\/ul>\n
\n- \nNon-cash charges included in cost of goods sold and operating expenses are estimated to be approximately $100 million. This includes:<\/p>\n<\/li>\n<\/ul>\n
\n- \nApproximately $80 million non-cash, stock-based compensation expense<\/p>\n<\/li>\n<\/ul>\n
\n- \nApproximately $20 million depreciation and amortization expense<\/p>\n<\/li>\n<\/ul>\n
\nFor 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<\/a>.<\/p>\nNon-GAAP Financial Measures<\/b><\/p>\n \nCertain non-GAAP financial measures are presented in this press release to provide information that may assist investors in understanding the Company\u2019s 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\u2019s 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 \u201cReconciliation of GAAP versus Non-GAAP Financial Results\u201d attached to this press release.<\/p>\n \nIn 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.<\/p>\n \nThe 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\u2019s operating results across the reporting periods. Tandem Choice did not impact any financial measures for the year ending December 31, 2025.<\/p>\n Conference Call<\/b><\/p>\n \nThe Company will hold a conference call and simultaneous webcast today at 4:30pm Eastern Time (1:30pm Pacific Time).
