Insider sales (SEC Form 4, open-market, last ~7 months) (INSP)
1 of 4 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.
| Trade date | Insider | Role | Shares | Value | % of holdings sold | 10b5-1 plan | Insider type |
|---|---|---|---|---|---|---|---|
| 2026-08-07 | Kelly Jason P | See Remarks | 963 | $57K | 4.8% | No | Too little history (no open-market trades in 2023–2025) |
| 2026-05-15 | Rondoni John | See Remarks | 2,641 | $114K | 8.9% | No | Routine (sold in Feb each year 2023–2025; this trade is outside those months) |
| 2026-05-14 | Rondoni John | See Remarks | 700 | $30K | 2.3% | No | Routine (sold in Feb each year 2023–2025; this trade is outside those months) |
| 2026-05-08 | McCormick Shawn | Director | 696 | $32K | 2.2% | Yes | Too little history (no open-market trades in 2023) |
% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).
Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

From Inspire Medical Systems, Inc.'s Latest SEC 10-K Filing (filed 2026-02-13)
Key Strengths & Strategy (as disclosed to the SEC)
- Our proprietary Inspire system is the first FDA, European Union ("EU") Regulation No. 2017/745 ("MDR" or "EU Medical Devices Regulation"), and Japan Pharmaceuticals and Medical Devices Agency-approved neurostimulation technology of its kind that provides a safe and effective treatment for patients with moderate to severe OSA.
- Our proprietary Inspire system is the first FDA-approved closed-loop neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA.
- Our proprietary algorithm tracks breathing patterns and the neurostimulator delivers electrical stimulation at the start of inspiration.
- We have developed the first FDA-approved neurostimulation technology that provides a safe and effective treatment for patients with moderate to severe OSA who have been confirmed to fail or cannot tolerate PAP treatments, such as CPAP.
Partnerships
- In 2007, we entered into an assignment and license agreement with Medtronic ("the Assignment and License Agreement") pursuant to which Medtronic assigned certain patents and trademarks to us and granted to us a worldwide, royalty-free license to certain other patents and technical information to make, use, import and sell products, and to practice methods in the field of electrical stimulation of the upper airway for the treatment of OSA ("the Field").
Legal & Regulatory Risks (Item 1A, quoted)
- Our products and operations are subject to extensive and changing laws, government regulation and oversight both in the U.S. and abroad, and our failure to comply with applicable requirements could harm our business.
- We may not receive the necessary approvals or certifications for our future products or expanded indications, and failure to timely obtain necessary approvals or certifications for our future products or expanded indications would adversely affect our ability to grow our business and our results of operations.
- The timing of FDA approval of a next generation product could have a significant impact on the carrying value of the inventory of our previous generation product, and therefore our results of operations.
- Failure to comply with post-marketing regulatory requirements could subject us to enforcement actions, including substantial penalties, and might require us to recall or withdraw a product from the market.
