Insights

Equity compensation and insider-trading analyst

Cadence SVP’s planned sale trims holdings but remains a moderate stake.

The Form 4 shows Sr. Vice President Paul Scannell executed an open-market sale of 10,500 Cadence Design Systems shares at $339.00 on May 1, 2026. Following the sale, he still directly owns 33,946 shares, indicating he retains a meaningful equity position.

The filing specifies the sale was made under a Rule 10b5-1 Trading Plan adopted on September 9, 2025. Such plans schedule trades in advance, so the timing is more mechanical than opportunistic. With only one sale and no derivative exercises disclosed, this appears as a routine liquidity event rather than a shift in overall insider exposure.
