The stock closed today at $155.40, down 10.0% over 30 days and -33.2% over 90 days from price levels near the sales dates. More significantly, this sale extends a strong pattern at Zscaler: all 5 of Geller's prior trades at this ticker were sales, each followed by a negative 90-day return ranging from -17.5% to -33.4%. His cross-ticker track record shows a 100.00% well-timed rate on 11 prior sells, with an average 90-day return of -17.0%. Today's stock price is -53.8% from its 52-week high of $336.27, underscoring sustained downward pressure.

Zscaler CEO Jagtar Singh sold 2,843 shares at $230.82; stock down -32.7% from 52-week high.

CEO Jagtar Singh sold 2,843 shares of Zscaler at $230.82 on 2025-12-16, reducing holdings by 0.8% to 347,857 shares. The current price of $226.43 reflects a -32.7% decline from the 52-week high of $336.27 and a -23.2% drop over 30 days. His timing across five prior sales at Zscaler shows a 4-of-5 well-timed pattern at the 90-day mark, with the most recent sale on 2025-09-16 yielding a -18.0% return over 90 days. Against this backdrop, the company's revenue growth of 23.3% year-over-year and recent quarterly revenue of $788.1M stand in contrast to a net loss of $-11.6M for the full fiscal year, indicating an unprofitable but growing enterprise. The significant stock decline since transaction and the CEO's historical track record of timing sales before downturns warrant attention to ongoing business fundamentals and forward guidance.

ZS CLO Schlossman sells 5,433 shares for $1,258,670.43; stock down 32.7% YTD, company unprofitable

Robert Schlossman, Chief Legal Officer of Zscaler, executed 2 separate sales totaling 5,433 shares for $1,258,670.43 on consecutive dates (3,084 shares at $230.82 on 2025-12-16 and 2,349 shares at $232.79 on 2025-12-17), reducing his holdings by 6.8%. The sale occurred while ZS stock trades 32.7% below its 52-week high and has declined 23.2% over 30 days. At the same-ticker level, his 5 prior ZS sells from October 2025 showed mixed near-term outcomes (ranging from +7.7% to +8.9% 30-day returns, with one recent sale on 2025-10-24 down 15.4%), with none yet measurable at the 90-day mark. Zscaler remains unprofitable on a full-year basis despite 23.3% annual revenue growth, creating an environment where insider equity dispositions warrant close monitoring of company trajectory and insider confidence signals.

CPO Adam Geller sells 3,680 shares at avg $231.69; stock down 23.2% in 30 days, unprofitable company

Adam Geller, Chief Product Officer at Zscaler, executed 2 separate sales totaling 3,680 shares for $852,607.56 on December 16-17, 2025, at an average price of $231.69, reducing his holdings by 6.8% to 50,528 shares post-transaction. The stock is currently priced at $226.43, down 23.2% over the past 30 days and trading 32.7% below its 52-week high, indicating significant recent momentum loss. Geller's prior 5 trades at Zscaler show a 100% well-timed rate at the 90-day mark, with all sales followed by declines averaging 18.2% over that horizon, and his broader cross-ticker track record shows a 100.00% well-timed rate on sells—a pattern of consistently selling into downturns. Against this backdrop, the company remains unprofitable (net income of $-11.6M in the latest quarter) despite robust revenue growth of 23.3% year-over-year, creating structural tension between growth and profitability that may inform his decision to liquidate a measurable portion of his position.

CFO Kevin Rubin sold 3,303 shares of Zscaler (ZS) at $230.82; stock down -32.7% from 52-week high.

CFO Kevin Rubin sold 3,303 shares at $230.82, reducing his holdings by 6.4% to 48,161 shares. The sale occurs in a context of significant recent deterioration: Zscaler's stock is trading at $226.43, down -32.7% from its 52-week high of $336.27 and down -23.2% over the past 30 days. The company reported a net loss of $-11.6M in its latest quarter and was unprofitable over its most recent full fiscal year, though it maintained solid revenue growth of +23.3% year-over-year with $788.1M in quarterly revenue. The timing of this insider sale during a period of weakness and operating losses—despite strong top-line growth—provides a factual data point for investors assessing ZS fundamentals and insider positioning.

CRO Rich sold 4,100 ZS shares at $230.82 (Dec 2025); stock now -32.7% from 52-week high amid unprofitable quarter.

Rich Michael J., CRO and President of WW Sales, sold 4,100 shares at $230.82 on 2025-12-16, reducing his holdings from 111,597 to 107,497 shares. The transaction occurs as Zscaler stock has declined 32.7% from its 52-week high of $336.27 and dropped 23.2% over the prior 30 days. The company reported a negative net income of $-11.6M in its latest quarter despite 23.3% annual revenue growth, raising questions about unit economics and profitability trajectory. Across his prior five trades at ZS, Rich achieved a 60% well-timed rate at the 90-day mark, suggesting some historical accuracy in execution; however, his most recent same-ticker sell (2025-09-16) was followed by a 90-day loss of -18.0%, and only three of five prior sells were ultimately well-timed, indicating inconsistent predictive value. The current price of $226.43 lies below the transaction price of $230.82, making this a decision point for evaluating whether the insider's actions presaged further downside or reflect routine portfolio management in a volatile environment.

ZS CLO Robert Schlossman sold 3,200 shares at $325.00 on 2025-10-24, now $323.00; stock at 52-week high.

Robert Schlossman, Chief Legal Officer, sold 3,200 shares (3.8% of his pre-transaction holdings) at $325.00, near the stock's 52-week high of $323.00 and current price of $323.00. This sale is part of a recent pattern: Schlossman executed four separate sells on 2025-10-02 at ZS, outcomes for which are not yet measurable, followed by this transaction 22 days later. Across his cross-ticker track record (20 prior sells), his 90-day well-timed rate is 42.86%, with an average 90-day return after sells of +16.2%, indicating his prior sales have generally preceded price gains rather than declines. The company reported revenue of $678,034,000 and net income of $-4,125,000 in its latest quarter, with annual revenue growth of +23.3% but full-year unprofitability. The clustering of insider selling activity within a narrow window alongside continued strong stock momentum warrants monitoring, though the transaction size relative to his 80,086-share post-transaction holding (3.8% reduction) is modest.

CLO Schlossman sells 7,006 shares at blended $305.57 for $2.1M on 2025-10-02; holds 76.1K post-sale.

Robert Schlossman, Chief Legal Officer of Zscaler, executed 5 separate sales totaling 7,006 shares for $2,140,851.24 at blended average price $305.57 on October 2, 2025, leaving him with 76.1K shares post-transaction. This represents an 8.4% reduction in his holdings at prices near the 52-week high ($316.50), with the current stock price at $307.58 showing minimal downside risk from transaction execution. His same-ticker sell history demonstrates strong prior timing: 4 of 4 measurable prior ZS sales posted negative 90-day returns, indicating he historically sold before subsequent declines at this ticker. However, the company remains unprofitable on a full-year basis despite 23.3% annual revenue growth, and his cross-ticker track record shows an average 90-day return of +13.2% following sells, suggesting his selling decisions have not consistently preceded meaningful price deterioration across his broader trading universe. The concentration of sales within a single trading day warrants monitoring of whether this represents discretionary portfolio activity or execution of a pre-arranged plan.

CEO Jagtar Singh sold 2,865 shares of ZS at $280.70 (2.9K shares, $804.2K); stock now at $279.46, -11.7% from 52-week high.

Chaudhry Jagtar Singh, as CEO & Chairman, sold 2,865 shares on 2025-09-16 at $280.70, reducing his holdings by 0.8% to 350,700 shares. The stock has since declined to $279.46, placing it 11.7% below its 52-week high, and has fallen 8.5% over the past 90 days. Examining Singh's same-ticker history at ZS, three of his four prior sells were well-timed at the 90-day mark—most recently a June 2025 sale followed by a 5.9% 90-day decline. Zscaler remains unprofitable on a full-year basis despite robust 23.3% annual revenue growth, with the most recent quarter showing negative net income of $4.1M against revenue of $678.0M. The timing and pattern of Singh's sales, combined with the company's ongoing path to profitability and stock retreat from 52-week highs, warrant monitoring of near-term performance and capital allocation decisions.

CLO Schlossman sells 3,832 shares of ZS at $280.70; all 5 prior same-ticker trades were well-timed 90d declines

Robert Schlossman, Chief Legal Officer, sold 3,832 shares at $280.70 on 2025-09-16, retaining 83,138 shares post-transaction. His sales activity at Zscaler shows a consistent pattern: all 5 prior trades at this ticker were well-timed, with each generating negative 90-day returns ranging from -5.9% to -8.1%, indicating he sold before subsequent declines. The current stock price of $279.46 is -11.7% from the 52-week high, and the 30-day move is +0.9% while the 90-day change is -8.5%. Zscaler's fundamentals show revenue of $678.0M with strong annual growth of +23.3%, but the company remained unprofitable (net income of -$4.1M) in its most recent fiscal year. The consistent negative 90-day outcomes across his same-ticker history warrants attention to whether this pattern continues or reflects sound discretionary judgment about the company's trajectory.
