MINNEAPOLIS, Feb. 11, 2026 (GLOBE NEWSWIRE) -- Inspire Medical Systems, Inc. (NYSE:INSP) (Inspire), 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 and year ended December 31, 2025.

"We are very excited with the strong finish to 2025. The team made excellent progress with the Inspire V launch, with clinical insights from the early phase of commercial adoption continuing to validate positive patient outcomes and improvements in therapy delivery," said Tim Herbert, Chairman and CEO of Inspire Medical Systems. "Despite the dynamic reimbursement landscape, our strong fourth quarter execution positions us well as we enter 2026."

"In the last week, we received clarification regarding the coding that should be used for the Inspire V procedure. Currently, healthcare centers and physicians should bill the most recent healthcare policies, be it a Medicare Administrative Contractor (MACs) or a commercial payor, and based on this clarification, we believe the code will transition to CPT code 64582 for the Inspire V procedure, including the use of a -52 modifier," continued Mr. Herbert. "While we are disappointed with this result, this clarification provides direction for us going forward, and we will work with payers, including the MACs, government agencies, commercial payers and physician societies to attempt to minimize the impact to the physician fee from this change. Additionally, we are seeking a long-term solution, namely the creation of a separate CPT code that would support appropriate reimbursement for the Inspire V procedure. We remain focused on our commitment to put the patient first and deliver strong patient outcomes. We believe we have a differentiated product, a strong team and that we can drive long-term profitable growth and shareholder value."

Full Year 2026 Outlook

The Company is revising its previously announced revenue outlook to be in the range of $950 million to $1.0 billion, which represents expected annual growth of 4% to 10%. This widened and revised range reflects the estimated impact on the first quarter for coding uncertainty as well as the range of outcomes that exist by moving to CPT code 64582 with the –52 modifier and related physician reimbursement rates.

Additionally, the Company expects annual adjusted operating margin in the range of 6% to 8%, net income per diluted share in the range of $1.23 to $1.81 and adjusted net income per diluted share in the range of $1.85 to $2.35.

The Company's outlook assumes an effective tax rate of approximately 44% to 49% and an adjusted effective tax rate of 26% to 28%, estimated weighted average diluted shares outstanding of approximately 29.4 million and capital expenditures between $45 million to $50 million.

Use of Non-GAAP Financial Measures This press release includes non-GAAP financial measures, including without limitation, adjusted operating income, adjusted operating margin, adjusted income before income taxes, adjusted income tax expense, adjusted effective tax rate, adjusted net income, adjusted net income per diluted 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 operating income as operating income or loss adjusted for items that are not indicative of our ongoing operations. Operating income is the most directly comparable GAAP financial measure to adjusted operating income. We define adjusted operating margin in this release as adjusted operating income divided by revenue. Operating margin is the most directly comparable GAAP financial measure to adjusted operating margin. Adjusted income before income taxes is defined as income before income taxes, adjusted for items that are not indicative of our ongoing operations. Income before income taxes is the most directly comparable GAAP financial measure. Adjusted income tax expense is defined as income tax expense, adjusted for items that are not indicative of our ongoing operations. Adjusted effective tax rate is adjusted income tax expense divided by adjusted income before income taxes. Income tax expense is the most directly comparable GAAP financial measure. Adjusted net income is defined as net income or loss, adjusted for items that are not indicative of our ongoing operations. Net income is the most directly comparable GAAP financial measure to adjusted net income. Adjusted net income per diluted share is calculated as adjusted net income divided by the dilutive weighted average shares outstanding. Net income per diluted share is the most directly comparable GAAP financial measure to adjusted net income per diluted share. 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, less non-operating income, adjusted for items that are not indicative of our ongoing operations. 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 and facilitate a more meaningful trend analysis without the distortion of various adjustment items. Management uses these measures principally as measures of our underlying operating performance, trends 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. These measures and their definitions are discussed in more detail below and 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.
