Sparks received two grants of NBT Bancorp Inc. common stock: 2,919 shares and 2,746 shares at zero price. Footnotes describe these as restricted stock unit and performance-based awards, with vesting occurring over time rather than as immediate, unrestricted cash compensation.

Why were some NBTB shares disposed of in Martin Randolph Sparks’ Form 4?

The Form 4 shows dispositions of 236 and 755 shares at $41.99 per share. These are coded as tax-withholding transactions, meaning shares were delivered to cover tax liabilities, not sold on the open market, which limits their informational value for trading sentiment.

What do the footnotes in Martin Randolph Sparks’ NBTB Form 4 explain?

The footnotes state that one grant under the Omnibus Restricted Stock Unit Agreement vests 20% annually and another reflects earned restricted stock units after a three-year performance period. This clarifies that awards are tied to service and performance conditions, not one-time cash bonuses.
