The company is U.S.-based and focuses on device-based solutions intended to address patients who are intolerant of continuous positive airway pressure (CPAP) therapy. The company’s mission centers on improving sleep and health outcomes through a combination of device design, clinical support, and physician training.
Business focus
Inspire’s core business is the development, manufacture, and commercial distribution of the Inspire system—an implantable device that stimulates the hypoglossal nerve to maintain airway patency during sleep. The company sells devices to hospitals and clinics and supports physician training and patient identification programs to drive clinical adoption. Primary markets include the United States, Europe, and select international markets where regulatory approvals and reimbursement pathways exist.
Products and technology
The Inspire system (high level)
The Inspire system is an implantable hypoglossal nerve stimulation therapy designed to treat moderate to severe obstructive sleep apnea in patients who cannot tolerate or do not benefit from CPAP. Key components and features include:
- Implanted pulse generator: placed subcutaneously and connected to stimulation leads.
- Stimulation lead(s): target the hypoglossal nerve to prompt tongue movement and help maintain open airways.
- Sensing lead or respiration sensor: detects breathing patterns to time stimulation with inspiration.
- Patient controller: allows patients to turn therapy on/off and adjust settings under physician guidance.
The therapy is indicated for adult patients meeting defined clinical criteria, following a physician assessment and often after a drug-induced sleep endoscopy or other diagnostic steps.
R&D, pipeline, and regulatory status
Inspire invests in product development aimed at improving therapy personalization, device longevity, and diagnostic/monitoring features. Public disclosures and filings historically referenced initiatives such as: closed‑loop stimulation concepts, enhanced sensing to better synchronize stimulation with respiration, and device software features for remote monitoring and patient engagement.
Regulatory status varies by market. The Inspire system is cleared or approved in multiple jurisdictions; precise approvals and labeling should be confirmed in the company’s regulatory filings and press releases for current status.

Financial performance
This section summarizes the types of financial metrics investors examine for "insp stock" and highlights notable recent guidance changes disclosed publicly.
Revenue and profitability
Inspire’s revenue base is driven by device sales, procedure volumes, and related services. A material update noted in recent company guidance was a downward revision for 2025 revenue to a range of $900 million to $910 million, down from a prior guidance range of $940 million to $955 million. Management cited factors such as a slower U.S. launch of a new device generation (Inspire V), inventory issues for an older model, and some patients delaying therapy while trying GLP‑1 weight‑loss drugs.
Such top‑line revisions have direct implications for sales growth expectations and margin outlooks. Investors tracking "insp stock" should review the most recent Form 10‑Q or Form 10‑K and quarterly investor presentations for reported trailing twelve‑month (TTM) revenue, gross margin, operating income or loss, and EPS figures.
Balance sheet highlights
Important balance sheet items for device companies like Inspire include cash and cash equivalents, marketable securities, short‑ and long‑term debt, and inventory levels. Recent commentary highlighted inventory pressures as a driver of guidance adjustments. For precise cash and debt balances, consult the latest quarter’s balance sheet in the company’s SEC filings.
Recent earnings and guidance
Recent earnings seasons for "insp stock" featured volatility tied to changes in sales guidance and product launch timing. The company’s downward guidance for its 2025 revenue and EPS expectations was a significant factor behind prior price moves and analyst revisions. Readers tracking "insp stock" should note the scheduled upcoming earnings release date listed in company investor materials and on finance portals to see reported results versus guidance.
Stock performance and historical trends
Price history
INSP has experienced notable volatility in recent periods. Market summaries reported that the stock had 31 moves greater than 5% over the prior year, illustrating frequent large swings. Examples cited in market commentary include:
- A one‑day drop of about 12.4% following billing‑code removal by two Medicare Administrative Contractors.
- A roughly 41.3% decline approximately six months earlier after the company slashed full‑year revenue and profit forecasts.
Multi‑period performance (1‑year, 5‑year, since‑IPO) is tracked on financial portals; one noted reference indicated that a $1,000 investment in INSP five years prior would be worth approximately $380.98 at the referenced price point—highlighting the stock’s cumulative performance over that horizon.
Key drivers of past performance
Several factors have materially influenced the INSP price historically:
- Regulatory and reimbursement developments (billing codes, payer coverage decisions).
- Clinical trial outcomes and product launch execution (timing of Inspire V rollout and associated inventory management).
- Company guidance revisions and quarterly earnings surprises.
- Broader market sentiment toward medtech stocks and investor reactions to volatility.
The recent removal of a key billing code by contractors (Noridian and CGS) created short‑term uncertainty about future payments for Inspire’s therapy and was reported to have triggered immediate selling pressure.

Following significant guidance revisions and sales headwinds, several firms revised ratings or price targets.

As of 2026-01-27, reports indicated this action introduced uncertainty about reimbursement for Inspire’s therapy and was linked to a 12.4% intraday share decline.

- CMS national coverage determinations or local Medicare Administrative Contractor (MAC) coding decisions.
- Company statements and appeals processes.

Risks and considerations
This neutral summary lists key risk categories commonly associated with medtech companies and specifically relevant to "insp stock":
- Clinical and regulatory risk: Efficacy outcomes, adverse events, and regulatory clearances can affect market opportunity and labeling.
- Reimbursement and insurance coverage risk: Coding decisions, payer coverage, and payment amounts materially affect procedure uptake and provider willingness to adopt the therapy.
- Market and competitive risk: Competing treatments for OSA (e.g., CPAP improvements, novel therapeutics, or alternate device approaches) can impact market share.
- Execution risk: Product launches, manufacturing scale‑up, and inventory management can affect revenue timing and margins.
- Financial risk: Variability in cash flows, working capital pressures, and exposure to foreign currency or concentration risk among key markets or distributors.
Investors researching "insp stock" should weigh these risks alongside the company’s reported financial position, pipeline prospects, and payer environment.
Trading information and derivatives
Liquidity and trading considerations
INSP has experienced periods of high volatility and significant intraday moves. Average daily volume and bid‑ask spreads can vary; higher volatility can widen spreads and increase trading costs for market orders. Traders should verify recent liquidity metrics on finance portals before placing orders.
Options and institutional holdings
An active options market can exist for mid‑cap medtech names; availability of listed options allows for hedging or defined‑risk strategies but also adds complexity. Institutional ownership levels are reported in filings and on major data platforms; significant institutional holders can influence trading dynamics via block trades or stewardship actions.
Valuation metrics
Common valuation metrics for "insp stock" include price‑to‑earnings (P/E), price‑to‑sales (P/S), price‑to‑book (P/B), and enterprise‑value multiples. Following revisions to guidance and volatile price moves, these ratios can change quickly. Analysts may value Inspire using a combination of discounted cash‑flow (DCF) models—reflecting uptake scenarios for Inspire therapy—and relative valuation against peer medtech comparables.
Investors should check current reported ratios on established finance sites and compare multiple valuation approaches to reflect differing assumptions about growth, margins, and reimbursement outcomes.
