Insights

Equity compensation analyst

Routine phantom stock dividend credit; no open-market trading.

Director Raffiq Nathoo was credited with 8.3153 phantom stock units linked to Cabot Corp common shares, at $69.49 per unit. These units reflect dividend equivalents on prior deferrals under the Non-Employee Director's Deferral Plan.

The award lifts his phantom stock balance to 1,292.3803 units and will be settled after his board service ends or per his distribution election. There is no cash exchanged now and no open-market buying or selling, so this is a routine compensation entry with limited signaling value for investors.
