STOCK-BASED COMPENSATION
The Company uses broad-based stock plans to attract and retain highly qualified officers and employees and to help ensure that management’s interests are aligned with those of its shareholders. The Company has also granted equity-based awards to directors, non-employees, and certain employees of Cellectis, the Company’s largest shareholder and former parent company prior to the completion of the Merger Transactions.
In December 2014, Legacy Calyxt adopted the Calyxt, Inc. Equity Incentive Plan (2014 Plan), which allowed for the grant of stock options, and in June 2017, it adopted the Calyxt, Inc. 2017 Omnibus Plan (2017 Plan), which allowed for the grant of stock options, restricted stock units (RSUs), performance stock units (PSUs), and other types of equity awards. As part of the Merger Transactions, the name of the 2017 Plan was amended to reflect the name change of the Company.

As of December 31, 2024, 874,607 shares were available for grant in the form of stock options, restricted stock, RSUs, and PSUs under the 2017 Plan. Stock-based awards currently outstanding also include awards granted under the 2014 Plan. No further awards are available for grant or will be granted under the 2014 Plan.

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.
