Significance 6

Chief Business Officer Steve Cashman sells 399,461 shares of BFLY for $1,893,341.68 in two transactions at $4.96 and $4.66

Steve Cashman, Chief Business Officer at Butterfly Network, executed two separate sales totaling 399,461 shares for $1,893,341.68 (blended average $4.74) on June 5 and June 8, 2026, reducing his holdings by 19.7%. At his same ticker, Cashman's two prior sells (April 2026 and February 2026) showed 90-day declines of -8.5% and +7.6%, with a 50% well-timed rate on sells—marking a less reliable timing pattern compared to his buy activity at BFLY, which posted 90-day returns of +62.6% and +61.6% with 100% well-timed execution. The current stock price of $5.12 sits 10.5% below the 52-week high of $5.72, and the recent 30-day momentum (+23.1%) and 90-day momentum (+34.0%) have pushed valuation near its annual peak despite the company reporting negative net income of $-12,677,000.00 against quarterly revenue of $26,530,000.00. The magnitude of this sale (nearly one-fifth of his pre-transaction position) in a rally environment, combined with his weaker sell-timing record at this ticker versus his strong buy execution, warrants investor attention to whether the company's continued unprofitability or near-peak valuation context influenced this liquidation.

Significance 6

Chief Business Officer Steve Cashman sold 200,000 shares of BFLY at $5.22; stock now at 52-week high of $5.45 after 38.0% 30-day rise.

Cashman sold 200,000 shares (-8.4% of holdings) at $5.22 on 2026-04-16, reducing his stake to 2,177,386 shares. The sale occurs with BFLY at its 52-week high of $5.45, following a sharp 38.0% rally over 30 days and 31.0% rise over 90 days. At BFLY specifically, Cashman's two prior buys (2025-08-25) each returned +27.0% and +26.2% over 30 days, with both generating strong 90-day returns (62.6% and 61.6%), indicating well-timed entry decisions. However, his most recent BFLY trade—a sell on 2026-02-26—showed -9.8% over 30 days, suggesting potential weakness ahead from that prior vantage point. The company remains unprofitable with net income of $-34.0M against latest-quarter revenue of $21.5M, though annual revenue grew 19.0%, creating a tension between operational scale and profitability. The timing of this sale—after a strong rally and at or near the 52-week peak—warrants investor attention alongside the company's ongoing cash burn profile.

Butterfly Network CBO Cashman sells 250.0K shares at $4.35 under pre-arranged 10b5-1 plan; retains 1.93M shares.

Cashman Steve, Chief Business Officer of Butterfly Network (BFLY), sold 250,000 shares at $4.35 on 2026-02-26 under a 10b5-1 trading plan adopted on 2025-09-12. This is a scheduled, pre-arranged transaction rather than a discretionary sale. The sale reduced his holdings by 11.5% from 2,181,884 shares to 1,931,884 shares, though he retains substantial ownership at 1.93M shares post-transaction. As a planned trade executed under Rule 10b5-1, this transaction reflects a pre-determined execution schedule rather than current market timing decisions by the executive.

Director Phanstiel buys 185,261 shares at $3.08; first position in unprofitable BFLY mid-recovery phase

Phanstiel S. Louise, a director, established a new position of 185,261 shares at $3.08, representing a $571,159.66 investment. This is her first shareholding in Butterfly Network, which reported net income of $-34.0M against revenue of $21.5M in the latest quarter and remains unprofitable on a full-year basis. The timing coincides with a significant 30-day rally of +60.9% and 90-day gain of +67.7%, though the stock remains -34.2% below its 52-week high of $4.82. The company shows underlying revenue growth of +24.5% year-over-year, indicating operational momentum despite current losses. The director's acquisition during a recovery phase in an unprofitable company warrants investor attention to whether this reflects confidence in a turnaround trajectory or signals the board's assessment of valuation.

Significance 6

Director Larry Robbins buys 21.4K shares of BFLY at $3.02; continues buying streak (5 prior purchases in 5 days, all untested).

Director Larry Robbins purchased 21,370 shares at $3.02 on 2025-12-11, adding to a rapid sequence of five purchases at the same ticker between 2025-11-20 and 2025-12-05. All five prior trades at BFLY remain unmeasured at the 30- and 90-day horizons, so no pattern of timing success or failure is yet observable at this ticker. Robbins' cross-ticker track record shows a 100% win rate on 10 prior buys with average 90-day returns of +213.8%, but this outsized performance does not transfer predictively to outcomes at BFLY—a company burning $34.0M annually despite +24.5% revenue growth. The continued accumulation in the face of ongoing losses and a stock 33.2% below its 52-week high warrants monitoring as the fundamental picture develops.

Director Robbins purchases 1,558,541 shares across 3 days (Dec 3–5, 2025) for $4,652,772.68 at avg $2.99; holdings +12.2% to 14.31M shares.

Larry Robbins, a director at Butterfly Network, executed 3 separate purchases totaling 1,558,541 shares for $4,652,772.68 between December 3–5, 2025, at a blended average price of $2.99—an increase of 12.2% to his post-transaction holdings of 14,313,685 shares. This substantial open-market accumulation occurred while the stock trades at $3.06, within its 52-week range of $1.33–$4.82 and up 96.2% over the prior 90 days. Robbins' cross-ticker track record is notably strong: 7 prior buys with a 100% 90-day win rate and average 90-day return of +213.8%, along with 6 prior sells all well-timed with a 100% win rate. At BFLY specifically, his 2 measurable prior buys (August 2024) each returned +47.0–47.5% at 30 days and +206.2–207.1% at 90 days. Against this backdrop of material accumulation and a consistent pattern of well-timed transactions across both BFLY and his broader portfolio, the company remains unprofitable (net income of $-34.0M on the latest full-year basis) despite 24.5% annual revenue growth, creating a dynamic tension between insider conviction and balance-sheet reality that warrants investor attention.

Director Larry Robbins purchases 2,800,000 shares at $2.35–$2.58 over 3 days for $6,784,060.00; post-transaction holdings reach 12,755,144 shares (+28.1%)

Larry Robbins, a director at Butterfly Network, executed 3 separate purchases totaling 2,800,000 (2.80M shares) for $6,784,060.00 over November 19–21, 2025, at a blended average price of $2.42, increasing his holdings from 9,955,144 to 12,755,144 shares (+28.1%). His prior trades at BFLY show a consistent pattern: 4 of 4 prior buys were well-timed at the 90-day mark, with gains ranging from +206.2% to +224.1%. The current price of $2.65 is +24.4% above the 30-day average and +74.3% above the 90-day average, suggesting sustained momentum following his acquisition window. However, this purchase occurs in the context of negative fundamentals: the company reported a net income of $-33,971,000.00 ($-34.0M) and remains unprofitable on a full-year basis, despite reporting annual revenue growth of +24.5%. The scale of this transaction—adding 2.8M shares to an already substantial 9.96M-share position—combined with his prior track record at this ticker indicates material conviction, though the profitability gap between revenue growth and operating losses warrants investor attention to the path to profitability.

BFLY CBO Cashman bought 50,000 shares at $1.63–$1.64 on 2025-08-25; stock now $1.57, -67.4% from 52-week high.

Chief Business Officer Steve Cashman purchased 50,000 shares across 2 transactions totaling $81,952.91 at an average price of $1.64 per share. The purchase occurred while BFLY trades at $1.57, down 19.1% over the prior 30 days and 35.4% over 90 days, with the stock trading 67.4% below its 52-week high of $4.82. The company is unprofitable (full-year net income was negative) despite recent revenue growth of 24.5% year-over-year. Cashman's post-transaction holdings of 2,324,474 shares represent a 2.2% increase in his position. The combination of significant insider accumulation amid sharp recent price declines and an unprofitable but growing business warrants close monitoring of whether this reflects confidence in a turnaround or reflects other considerations.

Director Larry Robbins buys 244,774 shares of BFLY at $1.07 on 2024-08-30, expanding stake to 9.96M shares amid -10.2% revenue decline and ongoing losses.

Director Larry Robbins purchased 244,774 shares at $1.07 on 2024-08-30, increasing his holdings from 9.71M to 9.96M shares. This transaction occurs within a sharp acquisition pattern—the director completed three separate purchases over three consecutive trading days (2024-08-28 through 2024-08-30)—suggesting sustained accumulation at a compressed valuation. However, the underlying business context is materially strained: the company reported quarterly revenue of $21.5M against net losses of $-15.7M, with full-year revenue contracting by -10.2% year-over-year and the company unprofitable on an annual basis. The timing relative to current market conditions shows mixed signals: the stock currently trades at $1.51, representing a +49.5% gain over 30 days and +59.3% over 90 days, yet still positioned -20.5% below its 52-week high of $1.90. The prior trades in this same ticker remain outcome-unmeasurable (all within the past three trading days), and the director's cross-ticker track record shows only 3 prior buys total, limiting confidence in pattern analysis.

Director Robbins buys 1,676,869 shares (1.68M) for $1,683,372.82 across 3 transactions at blended $1.00 average, raising stake to 9.71M shares (+20.9%)

Larry Robbins, a Director at Butterfly Network, executed 3 separate purchases totaling 1,676,869 shares for $1,683,372.82 at a blended average price of $1.00 per share on 2024-08-28 and 2024-08-29, increasing his holdings by 20.9% to 9,710,370 shares. The company is facing material headwinds: revenue declined 10.2% year-over-year to $21,487,000 in the latest quarter, and it generated negative net income of $-15,706,000 over its most recent full fiscal year. The stock is currently trading at $1.09, down 42.6% from its 52-week high of $1.90, though it has gained 9.6% over the past 90 days. With minimal cross-ticker buy history and no same-ticker outcomes yet measurable, this large discrete purchase represents a material personal capital commitment during a period of operational underperformance and relative stock weakness.
