Inspire Medical Systems, Inc. Announces Second Quarter 2025

Financial Results and Updates 2025 Outlook

MINNEAPOLIS, MN - August 4, 2025 - Inspire Medical Systems, Inc. (NYSE: INSP) (Inspire, or the company), a medical technology company focused on the development and commercialization of innovative, minimally invasive solutions for patients with obstructive sleep apnea, today reported financial results for the quarter ended June 30, 2025.

Recent Business Highlights

•Generated revenue of $217.1 million in the second quarter of 2025, an 11% increase over the same quarter last year

•Achieved gross margin of 84.0% in the second quarter of 2025

•Net loss was $3.6 million in the second quarter of 2025. Adjusted net income was $13.3 million

•Loss per share was $0.12 in the second quarter of 2025. Adjusted diluted earnings per share was $0.45

•Initiated the full launch of the Inspire V neurostimulation system in the U.S.

“The full launch of our FDA-cleared Inspire V system in the U.S. is an important milestone for Inspire. We have been receiving strong positive feedback from both surgeons and patients who value the simplified procedure and excellent patient outcomes enabled by this next generation technology,” said Tim Herbert, Chairman and CEO of Inspire. “In the near future, we look forward to presenting the clinical evidence collected to date.”

“The broad enthusiasm for Inspire V gives us confidence that it will be a growth engine for the Company. However, the U.S. commercial launch is progressing slower than expected, and the timeline to complete the full transition to Inspire V has been pushed forward, which will impact financial results for the year.”

“Importantly, we believe the operational headwinds are temporary, and actions are underway to address them,” continued Mr. Herbert. “We remain steadfast in our commitment to serving the many patients who struggle with untreated moderate to severe OSA, delivering strong patient outcomes and executing on our strategy to drive profitable growth and value creation for all stakeholders.”

Second Quarter 2025 Financial Results

Revenue was $217.1 million for the second quarter, an 11% increase from $195.9 million in the corresponding prior year period. U.S. revenue for the quarter was $207.2 million, an increase of 10% as compared to the prior year quarter. Second quarter revenue outside the U.S. was $9.9 million, an increase of 23% as compared to the second quarter of 2024.

Gross margin was 84.0% for the second quarter of 2025 compared to 84.8% in the second quarter of 2024. The decrease is primarily due to a $2.1 million charge associated with excess components inventory related to Inspire IV.

Operating expenses were $185.7 million for the second quarter of 2025, as compared to $160.9 million in the corresponding prior year period, an increase of 15%. This increase primarily reflected ongoing investments in the expansion of the U.S. sales organization, patient marketing expenses, and general corporate costs, partially offset by a reduction in R&D. Operating expenses also included an additional one-time charge of $11.2 million of accelerated stock-based compensation expense for employees who are retirement eligible in accordance with changes to the Inspire incentive award plan upon the employee’s death, disability, or retirement, and finally, $1.7 million in certain litigation-related legal expenses. These items do not reflect costs associated with our ongoing operations and a reconciliation table has been included at the bottom of this release.

Operating loss was $3.3 million for the second quarter of 2025, as compared to operating income of $5.1 million in the prior year period, a decrease of 165%.

Net loss was $3.6 million for the second quarter of 2025 as compared to a net income of $9.8 million in the corresponding prior year period. The net loss includes a $4.0 million non-cash impairment of a strategic investment. Adjusted EBITDA for the second quarter of 2025 was $44.1 million as compared to $38.7 million in the corresponding prior year period. The diluted net loss for the second quarter of 2025 was $0.12 per share, as compared to a net income of $0.32 per share in the prior year period. The adjusted net income for the second quarter of 2025 was $0.45 per share.

As of June 30, 2025, cash, cash equivalents, and investments were $410.7 million compared to $516.5 million on December 31, 2024.

Executive Retirement

“Randy Ban, our Executive Vice President of Patient Access and Therapy Development, recently notified us of his intention to retire on January 30, 2026. During his tenure, Randy has been one of Inspire’s most influential leaders, and as our initial commercial leader, he played a significant role in advancing access to Inspire therapy and building a strong, mission-driven organization. We are grateful for Randy’s many contributions and wish him the best in his retirement,” concluded Mr. Herbert.

Full Year 2025 Guidance

Inspire currently anticipates 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. This compares to the prior guidance range of $940 to $955 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 $0.40 to $0.50. This compares to the prior guidance of $2.20 to $2.30 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.
