13.          Stock-Based Compensation


In May 2024, the Company adopted the NBT Bancorp Inc. 2024 Omnibus Incentive Plan (the “Stock Plan”) replacing the 2018 Omnibus Incentive Plan. Under the terms of the Stock Plan, equity-based awards are granted to directors and employees to increase their direct proprietary interest in the operations and success of the Company. The Stock Plan assumed all prior equity-based incentive plans and any new equity-based awards are granted under the terms of the Stock Plan. Restricted shares granted under the Plan typically vest after three or five years for employees and one year for non-employee directors. Restricted stock units granted under the Stock Plan may have different terms and conditions. Performance shares and units granted under the Stock Plan for executives may have different terms and conditions. Since 2011, the Company primarily grants restricted stock unit awards. Stock option grants since that time were reloads of existing grants which terminate ten years from the date of the grant. Under terms of the Stock Plan, stock options are granted to purchase shares of the Company’s common stock at a price equal to the fair market value of the common stock on the date of the grant. Shares issued as a result of vesting of restricted stock unit awards and stock option exercises are funded from the Company’s treasury stock.

The Company has outstanding restricted stock granted from various plans at December 31, 2025. The Company recognized $5.3 million, $6.0 million and $5.1 million in stock-based compensation expense related to these stock awards for the years ended December 31, 2025, 2024 and 2023, respectively. Tax benefits recognized with respect to restricted stock units were $2.7 million, $1.5 million and $1.3 million for the years ended December 31, 2025, 2024 and 2023, respectively. Unrecognized compensation cost related to restricted stock units totaled $5.5 million at December 31, 2025 and will be recognized over 1.5 years on a weighted average basis. Shares issued are funded from the Company’s treasury stock. The following table summarizes information for unvested restricted stock units outstanding as of December 31, 2025:

About Stock Compensation Disclosures

Stock-based compensation disclosures detail the equity awards granted to employees and executives — including stock options, restricted stock units (RSUs), and performance shares — along with the valuation methods and assumptions used to expense them. This section reveals the true cost of talent retention and the alignment between management incentives and shareholder interests.

Key signals: total unrecognized compensation expense and its expected recognition period signal future earnings headwinds from already-granted awards. For stock options, examine Black-Scholes assumptions — expected volatility, risk-free rate, and expected term — as understating any of these reduces reported compensation expense. Compare stock compensation expense as a percentage of revenue against peers to assess dilution cost. Watch vesting schedules for acceleration clauses tied to change-of-control events. Performance-based awards with undemanding targets may indicate weak governance. Add back stock compensation to operating cash flow to calculate a more conservative free cash flow figure.
