Curet Myriam Buy
5 shares
$804
@ $160.72
Significance 4/10

Director Curet nets 1-share sale across 4 transactions (mixed buys and sells); currently $117.29 vs 52-week high of $215.42.

Curet Myriam executed 4 separate transactions over five months: 2 purchases totaling 5 shares for $803.62 and 2 sales totaling 6 shares for $615.55, resulting in a net 1-share sale. The buying occurred at $163.84 and $148.26 (March and April), while the selling occurred at much lower prices of $153.22 and $77.28 (May and August). This price progression—with the August sale at $77.28 representing a 53% decline from the March purchase price of $163.84—suggests the director was selling at depressed valuations. Currently at $117.29, the stock has recovered from the August lows but remains 45.6% below its 52-week high of $215.42. The director's post-transaction holdings of 3,365 shares represent minimal portfolio impact (net change of -1 share), making this a marginal activity that does not materially alter her director-level position.

Buchholz Richard Sell
Chief Financial Officer
11,000 shares
$1,027,290
@ $93.39
Significance 6/10

CFO Buchholz sold 11,000 INSP shares at $93.39; stock down 56.4% from 52-week high, he's now down to 44,867 shares held

Buchholz sold 11,000 shares at $93.39, reducing his position by 19.7% to 44,867 shares post-transaction. The timing is notable: his prior sell at INSP on 2024-04-17 posted a 90-day return of -36.6%, representing a well-timed exit, and this new sale occurs as the stock has fallen 25.0% over the last 30 days and 31.5% over 90 days from elevated levels ($216.71 52-week high). Current price of $94.51 sits 56.4% below that high, suggesting material deterioration in valuation since peak. The company posted net income of $-3,592,000.00 in the latest quarter despite revenue growth of 28.5% year-over-year, indicating profitability challenges beneath top-line expansion. The prior INSP transaction's favorable timing pattern—where the stock subsequently declined—provides historical context for evaluating whether the insider again anticipated downside.

Ban Randy Sell
See Remarks
25,584 shares
$4,694,766
@ $183.50
Significance 7/10

Ban Randy sells 25,584 shares of INSP for $4.7M across 10 transactions on 2025-02-13, reducing holdings by 77.9%

Ban Randy executed 10 separate sales totaling 25,584 shares for $4,694,765.58, reducing his stake from 32.8K shares to 7.3K shares (a -77.9% reduction). The sales occurred across a narrow price band ($178.54–$187.66) at a blended average price of $183.50, trading against a current price of $180.08 and a 52-week high of $251.19. His prior 5 sales at INSP all showed negative 90-day returns (ranging from -5.1% to -8.8%), meeting his pattern of well-timed exits at this ticker. The scale and structure of this filing—a nearly complete liquidation across multiple tranches in a single day—stands out against his holdings and warrant investor scrutiny regarding confidence in the company's near-term trajectory.

Rondoni John Sell
Chief Technology Officer
8,703 shares
$1,683,731
@ $193.47
Significance 7/10

CTO Rondoni John sold 8,703 shares for $1,683,730.99, reducing INSP holdings by 43.4% to 11,348 shares

Rondoni John, Chief Technology Officer at Inspire Medical Systems (INSP), executed 4 separate sales totaling 8,703 shares for $1,683,730.99 at a blended average price of $193.47 on 2024-11-01, cutting his holdings nearly in half from 20,051 to 11,348 shares. His prior trades at INSP demonstrate a strong timing pattern: of 5 prior same-ticker sales (3 in March, 2 in August 2024), all 3 with measurable 90-day outcomes showed negative post-sale returns, indicating well-timed exits ahead of declines. The current stock price of $199.00 reflects a -7.4% decline over the prior 30 days and sits -20.8% from its 52-week high of $251.19, suggesting the downward trend was underway at sale. While INSP shows strong fundamentals (revenue growth of +53.2%, net income of $18,497,000.00), the stock carries a historically elevated P/E of 180.91, and the company was unprofitable over its most recent full fiscal year despite recent quarterly profitability—conditions that may explain why a C-level executive with a pattern of well-timed sells chose to substantially reduce exposure.

Rondoni John Sell
Chief Technology Officer
5,000 shares
$949,143
@ $189.83
Significance 7/10

Inspire Medical CTO John Rondoni sells 5,000 INSP shares for $949.1K in 2 separate transactions at $189.16–$190.04

John Rondoni, CTO of Inspire Medical Systems (INSP), executed 2 separate sales totaling 5,000 shares for $949,143.12, reducing his holdings from 16,379 to 11,379 shares (a 30.5% reduction). The stock trades at $191.48 today, near the transaction prices of $189.16 and $190.04. Notably, Rondoni's prior 5 sales at INSP occurred in February and March 2024, all of which were well-timed at the 90-day mark (each followed by negative 90d returns ranging from -10.5% to -14.1%), and his cross-ticker track record shows a 100.00% well-timed rate across 7 prior sells. The company trades at a P/E of 957.40 with elevated valuation metrics (market cap $5.7B), though it demonstrated strong recent revenue growth of +53.2% and posted $9.8M net income last quarter. The continued insider selling pattern after months of prior exits, combined with a consistently demonstrated ability to exit before subsequent declines, warrants investor attention alongside the stock's current proximity to its 52-week high of $251.19.

Ban Randy Sell
Chief Commercial Officer
21,000 shares
$4,032,946
@ $192.05
Significance 7/10

CCO Ban Randy sold 21,000 shares ($4.0M) over 2 days at avg $192.05; holdings cut 87.3% to 3.1K shares.

Ban Randy, Chief Commercial Officer at Inspire Medical Systems, executed 9 separate sales over August 15–16, 2024, totaling 21,000 shares for $4,032,945.90 at a blended average price of $192.05. This represents a -87.3% reduction in his holdings, leaving only 3.1K shares post-transaction. The multi-day execution across price points ranging from $187.10 to $194.91 suggests a planned liquidation rather than a reactive single-date sale. Ban Randy's prior trading activity at INSP shows a 2 of 2 pattern of well-timed sells (both prior trades posted negative 90-day returns of -12.8% and -16.5%), though his cross-ticker track record has produced only a 12.2% average 30-day return against a -14.6% average 90-day return. The company's fundamentals present a disconnect: while annual revenue growth reached +53.2% and the latest quarterly revenue totaled $195,885,000.00, the company remains unprofitable on a full-year basis and carries an elevated P/E of 970.15. The stock is currently -22.8% from its 52-week high of $251.19 despite a +35.0% 30-day rally, leaving investors to assess whether the CCO's substantial share liquidation reflects confidence in near-term momentum or prudent reduction of concentrated exposure.
