SNPS SYNOPSYS INC Insider Trading

SNPS CFO Shelagh Glaser sells 3,657 shares for $1,685,035.89 on 2025-12-19

Glaser executed 2 separate sales totaling 3,657 shares for $1,685,035.89 on 2025-12-19 at a blended average price of $460.77, reducing her holdings by 17.0% to 17,842 shares. The current price of $481.24 sits 25.4% below the 52-week high of $645.35, despite a strong 23.9% gain over the past 30 days. Reviewing Glaser's cross-ticker track record, her 4 prior sells averaged -0.0% return over 90 days with a 50.00% well-timed rate; at SYNPS specifically, 2 of her 4 prior sales corresponded with subsequent declines (well-timed 90-day mark). The current sale occurs in a context where the stock has recovered recently but remains significantly below its peak, and Glaser's historical pattern shows mixed timing outcomes across both tactics and the specific ticker.

Chief Accounting Officer sold 15,873 shares for $7,837,408.41 across 2 transactions; stock down 19.2% in 30 days and 24.0% from 52-week high.

Kankanwadi Sudhindra executed two separate sales totaling 15,873 shares for $7,837,408.41, reducing his holdings by 43.6% (from 36,393 to 20,520 shares) over three days in September 2025. The sales occurred at $482.00 and $500.90 per share, blending to $493.76—above the current price of $490.32 but in a stock that has declined 19.2% over the last 30 days and sits 24.0% below its 52-week high. At the same ticker, Sudhindra's five prior sales showed mixed timing: only 1 of 5 was well-timed at the 90-day mark, indicating his historical SNPS trades have not consistently preceded downturns. The Company maintains a solid operating position (P/E 45.61, market cap $91.1B, quarterly revenue $1.7B) with modest annual growth of 4.9%, so this sale occurs against a backdrop of recent stock weakness rather than fundamental deterioration.

Director Robert G Painter bought 350 SNPS shares at $425.44; stock down 35.0% from 52-week high at $419.20 current.

Director Painter purchased 350 shares of Synopsys at $425.44, increasing his holdings by 18.0% to 2,291 shares total. The purchase occurred after the stock has declined 35.0% from its 52-week high of $645.35 and is trading 30 days down 32.2%. His prior open-market trade history shows 9 sales with an average 90-day return of +13.0%, indicating his prior sells were poorly timed (the stock rose after he exited). Current fundamentals show revenue of $1,739,737,000.00 (latest quarter) with a P/E of 39.00, suggesting the company remains profitable despite recent share price weakness. The timing and magnitude of this director-level accumulation against a backdrop of substantial recent depreciation warrants investor attention to the underlying business outlook and any material developments that may have prompted this addition to his stake.

SNPS CFO Glaser Shelagh sold 3,655 shares at $609.77 for $2.2M on 2025-09-05, reducing holdings 19.3%

CFO Shelagh Glaser executed 2 separate sales totaling 3,655 shares for $2,228,709.35 at $609.77, reducing her holdings by 19.3% from 18,972 to 15,317 shares. The transaction occurred near the stock's 52-week high ($645.35), though at a -6.4% discount to that peak, and at a price $5.40 above the current market level of $604.37. Glaser's cross-ticker track record shows 2 prior open-market sales with an average 90-day return of +23.9% — indicating that her previous sales missed subsequent gains. Her prior 2 trades at SNPS specifically (both on 2025-06-06) posted identical +23.9% 90-day returns, establishing a pattern of sells that did not precede declines. The filing reflects a material reduction in her stake at elevated valuations, executed while the stock remains up +20.7% over 90 days.

Ghazi Sassine (SNPS CEO) sold 11,366 shares for $6,694,725.17 on 2025-09-02; retains 71,615 shares post-sale.

Ghazi Sassine sold 11,366 shares at $589.01, reducing his holdings by 13.7% to 71,615 shares. The stock subsequently declined 6.9% over the next 30 days to $592.12 current price. Across his prior 5 SNPS sales, timing has been inconsistent: his June 2025 sale was followed by +14.2% in 30 days, while his August 2024 and March 2025 sales saw declines of -8.5% and -5.4% respectively. At the same-ticker level, only 1 of 5 prior sells proved well-timed at the 90-day mark. The current 52-week context shows the stock trading 8.2% below its high, with near-term weakness offsetting stronger 90-day gains of +22.8%.

CRO Richard S. Mahoney sold 9,010 shares of SNPS at $471.21 avg for $4.2M, reducing holdings 85.9%

Richard S. Mahoney, Chief Revenue Officer, executed 3 separate sales totaling 9,010 shares for $4,245,645.25 at blended average price $471.21 on 2025-06-18, reducing his holdings from 10,495 shares to 1,485 shares—a 85.9% reduction. His prior trades at SNPS show 4 of 5 were well-timed at the 90-day mark, suggesting pattern awareness; however, his cross-ticker track record of 7 prior sells achieved only a 57.14% well-timed rate with average 90-day return of -4.6%, indicating consistency is not assured. The current stock price of $470.53 is -24.3% from the 52-week high of $621.30 and -6.2% over the last 30 days, placing the CRO's sale near recent weakness in absolute price terms, though only 0.14% below the transaction average.

CFO Shelagh Glaser sells 7,310 shares at $485.72 for $3.6M; holds 15,291 shares post-sale

Shelagh Glaser, CFO of Synopsys, executed 2 separate sales totaling 7,310 shares for $3,550,608.82 at $485.72 per share on 2025-06-06. The sale reduced her holdings by 32.3% from 22,601 to 15,291 shares. The current stock price of $495.77 is 20.2% below the 52-week high of $621.30, though the stock has risen 2.7% over the prior 30 days and 15.1% over 90 days. Without information on whether this sale was part of a pre-established trading plan, the multiple-transaction structure and the magnitude of the reduction warrant observation of any broader insider activity patterns and company performance in the coming periods.

SNPS CEO Ghazi Sassine sold 11,366 shares (13.7% of holdings) for $5.2M on 2025-06-02 at $457.93; stock now $466.26, -25.0% from 52-week high.

Ghazi Sassine, the company's President and CEO, executed a substantial single-tranche sale of 11,366 shares worth $5,204,785.78, reducing his holdings from 82,955 to 71,589 shares. The transaction occurred at $457.93, a price 1.8% below the current market price of $466.26 and significantly below the 52-week high of $621.30; the stock is currently -25.0% from that peak. Sassine's cross-ticker track record shows 4 prior open-market sells averaging -1.8% 30-day return and -0.9% 90-day return, with a 25.00% well-timed rate. However, at SNPS specifically, his timing has been mixed: of 4 prior sales at this ticker, only 1 was well-timed at the 90-day mark, with an equal split between positive and negative outcomes. The sale follows SNPS revenue of $1,604,266,000 and net income of $345,332,000 in the latest quarter, alongside annual revenue growth of +4.9% and a P/E of 33.45. This disposal represents a material reduction in the CEO's stake while the company maintains profitability, warranting investor attention to the timing and magnitude relative to his historical pattern at this specific ticker.

De Geus sells 15,705 SNPS shares at $444.42; prior 5 trades at ticker 100% well-timed (90d -14.9% to -21.1%)

De Geus sold 15.7K shares on 2025-03-06 at $444.42, reducing his holdings by 11.9% from 132.4K to 116.7K shares for $7.0M. This sale follows a striking pattern: his 5 prior open-market sales at SNPS (July 2024) were all well-timed, with 90-day returns ranging from -14.9% to -21.1%, meaning the stock declined after each sale. His cross-ticker track record also shows strong timing acumen, with a 90-day well-timed rate of 80.00% across 15 prior sells. Currently, SNPS is down 30.8% from its 52-week high of $621.30 and has declined 18.2% over 30 days, suggesting material price deterioration since the March sale. The consistency of well-timed sells at this specific ticker merits investor attention, as it points to systematic advantage in recognizing inflection points rather than routine portfolio rebalancing.

CEO Ghazi Sassine sold 11,366 shares of SNPS at $463.75 on 2025-03-03 for $5.3M, reducing holdings by 13.8%; stock has since declined 28.3% from 52-week high.

Ghazi Sassine, PRESIDENT AND CEO, sold 11,366 shares at $463.75, exiting $5.3M of his position and reducing holdings to 70,922 shares (70.9K shares). The sale occurred near the 52-week high range; SNPS is now trading $445.47, down 28.3% from its 52-week high of $621.30 and down 15.2% over the past 30 days. Examining his prior SNPS trades, Sassine's timing has been inconsistent: his August 2024 sale was followed by an 8.5% decline in 30 days (well-timed), but his May 2024 and February 2024 sales saw subsequent gains or minimal losses. Across all tickers in his track record, his 90-day well-timed rate is 33.33%, indicating his sales have historically preceded stock declines less than half the time. The current price weakness occurred after this transaction, but the insider's prior pattern at SNPS—where only 1 of 3 previous sales was well-timed at the 90-day mark—does not establish a consistent forecasting signal.
