“The Inspire team had a very productive third quarter focusing on the transition to the Inspire V system while delivering very strong results globally,” said Tim Herbert, Chairman and Chief Executive Officer of Inspire Medical Systems. “Further, at recent industry meetings, we presented clinical evidence demonstrating that the Inspire V system offers enhanced performance, building on the strong foundation established by our legacy systems.”
“Patient safety is paramount, and with our Inspire V study in Singapore of 44 patients and the Limited-Market-Release study of over 100 patients in the United States, 100% of patients had a successful device implant,” continued Mr. Herbert. “Device performance was equally impressive starting with a 20% reduction in surgical procedure time, and statistically significant and clinically relevant reductions in disease severity. Recent field experience with the Inspire V system is generating very positive feedback from clinicians, and the team is making excellent progress with the U.S. launch with over 75% of centers ready to transition to Inspire V. We remain laser-focused on execution and with our strong performance and disciplined investments and cost management, we are reaffirming our full year revenue guidance of $900 to $910 million and increasing our diluted net income per share guidance to $0.90 to $1.00, up from $0.40 to $0.50 previously. I am very proud of how our team is executing and I look forward to a strong finish to the year.”
Third Quarter 2025 Financial Results
Revenue was $224.5 million for the third quarter, a 10% increase from $203.2 million in the corresponding prior year period. U.S. revenue for the quarter was $214.4 million, an increase of 9% as compared to the prior year quarter. Third quarter revenue outside the U.S. was $10.1 million, an increase of 37% as compared to the third quarter of 2024.
Gross margin was 85.8% for the third quarter of 2025 compared to 84.1% in the third quarter of 2024. The year-over-year increase was due to higher sales volume and higher Inspire V sales mix, which carries a lower cost of goods sold.
Operating expenses were $183.1 million for the third quarter of 2025, as compared to $156.5 million in the corresponding prior year period, an increase of 17%. This increase primarily reflected patient marketing expenses and general corporate costs, partially offset by a reduction in R&D. Operating expenses also included an additional
$1.3 million in certain litigation-related legal expenses which do not reflect costs associated with our ongoing operations. A reconciliation table has been included at the bottom of this release.
Operating income was $9.6 million for the third quarter of 2025, as compared to $14.3 million in the prior year period.
Net income was $9.9 million for the third quarter of 2025 as compared to $18.5 million in the corresponding prior year period. Adjusted EBITDA for the third quarter of 2025 was $44.0 million as compared to $44.5 million in the corresponding prior year period. The diluted net income for the third quarter of 2025 was $0.34 per share, as compared to $0.60 per share in the prior year period. The adjusted net income for the third quarter of 2025 was $0.38 per share, as compared to $0.60 per share in the prior year period.
As of September 30, 2025, cash, cash equivalents, and investments were $410.9 million compared to $516.5 million on December 31, 2024.
Full Year 2025 Guidance
Inspire is maintaining full year 2025 revenue guidance to be in the range of $900 million to $910 million, which represents growth of 12% to 13% over full year 2024 revenue of $802.8 million.
The company is maintaining its full year 2025 gross margin guidance of 84% to 86%.
Inspire anticipates diluted net income per share guidance for the full year 2025 to be in the range of $0.90 to $1.00. This compares to the prior guidance of $0.40 to $.50 per share.

Use of Non-GAAP Financial Measures
This press release includes the non-GAAP financial measures of Adjusted net income, Adjusted earnings per share ("EPS"), Adjusted EBITDA, and Adjusted EBITDA margin, which differ from financial measures calculated in accordance with U.S. generally accepted accounting principles (“GAAP”).
We define Adjusted net income as net income or loss, plus items that are not indicative of our ongoing operations. Net income is the most directly comparable GAAP financial measure to adjusted net income. Adjusted EPS is calculated as adjusted net income divided by the dilutive weighted average shares outstanding. Diluted EPS is the most directly comparable GAAP financial measure to adjusted EPS. We define Adjusted EBITDA as net income or loss, less interest income, plus interest expense, plus income tax expense, plus depreciation and amortization, plus stock-based compensation expense, plus litigation-related legal expenses and other non-operating expenses less
non-operating income. Net income is the most directly comparable GAAP financial measure to Adjusted EBITDA. We define Adjusted EBITDA margin in this release as Adjusted EBITDA divided by revenue. Net income margin is the most directly comparable GAAP measure to Adjusted EBITDA margin. Reconciliations of these non-GAAP financial measures to their most directly comparable GAAP measures are included in this press release.
These non-GAAP financial measures are presented because we believe they are useful indicators of our operating performance. Management uses these measures principally as measures of our operating performance and for planning purposes, including the preparation of our annual operating plan and financial projections. We believe these measures are useful to investors as supplemental information and because they are frequently used by analysts, investors and other interested parties to evaluate companies in our industry. We also believe these non-GAAP financial measures are useful to our management and investors as a measure of comparative operating performance from period to period.
These non-GAAP financial measures should not be considered as an alternative to, or superior to, the most directly comparable GAAP financial measures, as measures of financial performance or cash flows from operations, as a measure of liquidity, or any other performance measure derived in accordance with GAAP, and they should not be construed to imply that our future results will be unaffected by unusual or non-recurring items. In addition, Adjusted EBITDA is not intended to be a measure of cash flow for management’s discretionary use, as it does not reflect certain cash requirements such as tax payments, capital expenditures and certain other cash costs that may recur in the future. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized. In evaluating our non-GAAP financial measures, you should be aware that in the future we may incur expenses that are the same as or similar to some of the adjustments in this presentation. Our presentation of non-GAAP financial measures should not be construed to imply that our future results will be unaffected by any such adjustments. Management compensates for these limitations by primarily relying on our GAAP results in addition to using non-GAAP financial measures on a supplemental basis. Our definition of these non-GAAP financial measures is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation.

While we may elect to update such forward-looking statements at some point in the future, unless required by applicable law, we disclaim any obligation to do so, even if subsequent events cause our views to change. Thus, one should not assume that our silence over time means that actual events are bearing out as expressed or implied in such forward-looking statements.
