Routine executive stock sale with small size and pre-set 10b5-1 plan.

Senior vice president Paul Scannell sold 1,071 shares of Cadence Design Systems common stock at $345.06 per share. The transaction leaves him with 32,181 directly held shares, indicating he retains a substantial equity stake.

An additional 75 shares were surrendered at $347.24 per share solely to satisfy taxes from a Restricted Stock Award vesting, which is an administrative, non-market step.

Rule 10b5-1 Trading Plan regulatory

"The transaction reported in this Form 4 was effected pursuant to a Rule 10b5-1 Trading Plan adopted on 9/9/2025"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

Restricted Stock Award financial

"Shares withheld to satisfy tax obligations arising out of vesting of Restricted Stock Award"

A restricted stock award is company shares given to an employee or executive that cannot be sold or fully owned until certain conditions—like staying with the company for a set time or hitting performance targets—are met. Think of it as a gift that only becomes yours after you fulfill specific obligations; for investors, these awards matter because they can increase the total shares outstanding when they vest, reveal how management is being paid and motivated, and create potential selling pressure when restrictions lift.

tax-withholding disposition financial

"transaction_action: "tax-withholding disposition" for the F-code transaction"

A tax-withholding disposition is an event or transaction—such as selling or transferring securities, exercising options, or receiving compensation—that triggers a requirement to hold back part of the payment and remit it to tax authorities. It matters to investors because it reduces the cash they receive immediately and can change the timing and amount of taxable income, like a cashier taking a portion of your sale proceeds to pay taxes before you get the rest.

open-market sale financial

"transaction_action: "open-market sale" for the S-code transaction"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
