SENS Senseonics Holdings, Inc. Insider Trading

Director Douglas Roeder adds 22,686 shares while stock trades down 63% from 52-week high; repeat buyer at declining prices in loss-making medical device company.

Director Douglas Roeder purchased over 22,600 shares, increasing his stake by nearly one-fifth—his sixth open-market purchase in the last three years. The timing is notable: the stock is trading well below its 52-week high and has declined significantly over the past several months, suggesting he is buying during a sustained pullback rather than at peak levels. Senseonics is not yet profitable and posted a net loss in both the full year and most recent quarter, though the company is growing revenue at a strong rate year-over-year. Roeder has no track record of open-market sales and has consistently added shares on the open market, but all five of his prior purchases at this ticker remain too recent to assess whether they preceded gains or further declines. His repeated buying into a falling stock in a loss-making but growing medical device company could reflect conviction in a longer-term turnaround, but the pattern of purchases at steadily lower prices over several years warrants scrutiny about whether he is averaging down into a deteriorating situation.

SENS CEO Timothy T Goodnow buys 17,225 shares at $5.79; stock -59.1% from 52-week high, -16.0% in 30 days.

Goodnow purchased 17,225 shares at $5.79 on 2026-03-13, increasing his position to 651,243 shares (+2.7%), at a time when SENS trades -59.1% below its 52-week high of $15.44 and has declined -16.0% over the prior 30 days. His prior two buys at SENS both yielded positive 90-day returns (+12.8% and +2676.8%), establishing a pattern of well-timed entries at this ticker. However, the stock's current technical profile is sharply negative: it is deeply underwater from its recent peak and on an accelerating downtrend. Goodnow's cross-ticker track record shows exceptional average 90-day returns (+1841.1% with 100% win rate), but that cross-ticker strength does not necessarily transfer to this equity, where the company remains unprofitable with $-19.5M net income despite 56.9% annual revenue growth. The purchase occurs as the stock faces both momentum headwinds and valuation uncertainty tied to near-term profitability trajectory.

Director Roeder bought 17,500 SENS shares at $5.73 on 2026-03-13, extending 4-of-4 well-timed buy pattern (+2136.7% to +3692.2% 90d returns prior).

Douglas A. Roeder (Director) purchased 17,500 shares at $5.73, increasing his stake by 17.1% to 119,731 shares. This marks his fifth open-market buy at Senseonics, following four prior purchases all characterized by substantial 90-day returns: +2136.7% (2023-08-30), +3692.2% (2024-12-12), +3009.6% (2024-12-13), and +13.6% (2025-11-07). Across his cross-ticker track record, his buy transactions average +2213.0% 30-day return and +1783.0% 90-day return with a 100.00% win rate, establishing a pattern of well-timed accumulation. The current stock price of $6.31 is -59.1% from the 52-week high of $15.44 and has declined -16.0% over 30 days, while fundamentals show the company posted $8,095,000.00 in latest quarterly revenue with net income of -$19,530,000.00—unprofitable but growing revenue +56.9% year-over-year. The scale and consistency of prior gains at this ticker, combined with a director-level insider choosing to significantly increase holdings despite recent stock weakness, suggests confidence in valuation at this price level relative to medium-term prospects.

Director Steven Edelman buys 10,000 SENS shares at $6.55 amid cluster buy; stock down 76.4% from 52-week high, company unprofitable.

Steven Edelman, a Director of Senseonics Holdings, purchased 10,000 shares at $6.55 on 2025-11-10, increasing his holdings by 15.5% to 74,708 shares. This transaction is noteworthy because it occurs as part of a cluster pattern: 3 other insiders also bought within the past 14 days. The timing coincides with significant stock weakness—the current price of $6.18 represents a 76.4% decline from the 52-week high of $26.20, and a 29.8% drop over the past 30 days. Senseonics is unprofitable with a net income of $-19.5M against quarterly revenue of $8.1M, yet multiple directors are acquiring shares at depressed prices. This cluster activity warrants attention as a potential signal of insider conviction or preparedness to hold through operational challenges.

Director Roeder buys 15,000 SENS shares at $5.83; 3 other insiders also bought within 14 days amid stock -75.8% from 52-week high.

Douglas Roeder, a Director, purchased 15,000 shares at $5.83 on 2025-11-07, increasing his holdings by 17.7% to 99.7K shares. This transaction is noteworthy because it occurs within a cluster: 3 other insiders also bought SENS within the past 14 days, suggesting coordinated conviction at depressed valuations. Roeder's own timing record at this ticker is strong—his prior 3 buys at SENS all posted positive 90-day returns (ranging from +2053.0% to +2893.7%), and all 3 were well-timed at the 90-day mark. However, the stock has deteriorated significantly since the transaction: the current price of $6.33 is -75.8% below the 52-week high of $26.20 and down -24.6% over the prior 30 days. Against this backdrop, the company remains unprofitable (net income of $-19.5M over the full year) despite flat annual revenue growth of +0.4%, creating material uncertainty about the validity of even Roeder's previously reliable timing edge at this ticker.

CFO Sullivan buys 5,415 SENS shares at $5.88 amid 75.8% decline from 52-week high; cluster activity from 3 other insiders in 14 days

CFO Frederick T. Sullivan purchased 5,415 shares at $5.88 on 2025-11-07, increasing his holdings to 157,028 shares, in the context of SENS trading at -75.8% from its 52-week high of $26.20 and -24.6% over the past 30 days. Sullivan's prior buy at this ticker on 2024-12-12 achieved +3991.6% 30-day and +3130.0% 90-day returns, representing a well-timed prior purchase. The current buy occurs alongside coordinated purchasing by 3 other insiders within the past 14 days, forming a cluster acquisition pattern. Notably, the company reported negative net income of $-19.5M on quarterly revenue of $8.1M, indicating operational challenges amid the stock's sharp price compression from recent highs.

Director Roeder purchases 325,000 shares at $0.42 avg; 2 separate buys in cluster pattern with stock up +55.6% YTD

Douglas A. Roeder, Director at Senseonics Holdings, executed 2 separate purchases totaling 325,000 shares (325.0K shares) for $135,500.00 ($135.5K) on 2024-12-12 and 2024-12-13, increasing his holdings by 29.9% to 1,413,087 shares. The stock is trading at $8.81 current price, up 55.6% over the past 30 days but down 39.7% from its 52-week high of $14.60. Notably, 2 other insiders also bought within the past 14 days, forming a cluster buy pattern. Context is critical: Senseonics remains deeply unprofitable (net income of $-23,976,000.00 for the latest full fiscal year), though annual revenue growth of 3313.1% indicates rapid business expansion; the company's market cap stands at $5.2B despite minimal current profitability and quarterly revenue of only $4.3M.

CFO Frederick T. Sullivan buys 124,933 shares of SENS at $0.38 on 2024-12-12; cluster pattern with 2 other insiders buying within 14 days.

Sullivan, CFO of Senseonics Holdings, purchased 124,933 shares at $0.38, increasing his holdings from 2,353,911 to 2,478,844 shares (+5.3%). This acquisition occurred amid a severe disconnect between fundamentals and valuation: the company generated only $4,263,000 in latest quarterly revenue while posting a $-23,976,000 net loss, and remains unprofitable on a full-year basis, yet carries a $5.1B market cap. The purchase price of $0.38 reflects a 95.6% discount to the current market price of $8.62. Most significantly, this buy is part of a cluster pattern where 2 other insiders also purchased within the past 14 days, suggesting coordinated or aligned confidence despite the company's substantial operating losses and the stock's -41.0% retreat from its 52-week high of $14.60. Investors should examine whether this synchronized insider accumulation reflects genuine strategic conviction about turnaround prospects or reflects valuation-driven opportunism at a deeply depressed entry point in an unprofitable business.

CEO Goodnow purchased 315,000 shares of SENS at $0.31 on 2024-12-10; current price $6.15, up 1,887% from purchase.

Timothy T Goodnow, President and CEO, purchased 315,000 shares at $0.31, bringing his holdings to 11,310,355 shares. The purchase price represents a 57.9% discount to the current price of $6.15. While SENS shows explosive annual revenue growth of +3313.1%, the company remains unprofitable with a net loss of $23,976,000.00 over its most recent full fiscal year on quarterly revenue of just $4,263,000.00. A CEO share purchase in a fundamentally loss-making business at depressed valuations relative to recent trading levels merits attention, but the asymmetry between the stock's 52-week high of $14.60 and the transaction price of $0.31 suggests the purchase occurred during a significant valuation compression event rather than a sustained market opportunity.
