In April 2019, we adopted the 2019 Equity Incentive Plan (the “2019 Plan”). We previously registered 5,000,000 shares of Class A common stock that are or may become issuable under the 2019 Plan as stock options and other equity-based awards to employees, directors and executive officers. In August 2021, we adopted, and our shareholder approved the Amended and Restated 2019 Equity Incentive Plan (the "Amended 2019 Plan"), which amends and restates the 2019 Plan in its entirety. The

Amended 2019 Plan, among other things, increases the number of shares of Class A common stock available for issuance under the 2019 Plan by 2,860,367.

The Amended 2019 Plan provides eligible participants with compensation opportunities in the form of cash and equity incentive awards. The 2019 Plan is designed to enhance our ability to attract, retain and motivate our employees, directors, and executive officers, and incentivizes them to increase our long-term growth and equity value in alignment with the interests of our stockholders.

On August 31, 2021, we completed our previously announced merger with KushCo Holdings, Inc. ("KushCo"), pursuant to the terms of an Agreement and Plan of Merger, dated as of March, 31, 2021 (the "Merger Agreement"). See "Note 3 - Business Acquisitions" for additional details.

At the effective time of the Mergers, options to purchase shares of Class A common stock (the “Greenlane options”) and shares of Greenlane restricted stock were treated as follows:

•Each unvested Greenlane option, other than Greenlane options held by non-employee directors of Greenlane, accelerated and became vested in full;

•Each Greenlane option held by non-employee directors of Greenlane, whether vested or unvested, remained outstanding (and unvested, as applicable) in accordance with the terms of Greenlane’s equity plan covering each such option;

•Each unvested share of Greenlane restricted stock and each unvested common unit of the Operating Company, other than Greenlane restricted stock or Greenlane restricted common units held by non-employee directors of Greenlane, accelerated and became vested in full in accordance with the terms of Greenlane’s equity plan covering each such award; and

•Each unvested share of Greenlane restricted stock or Greenlane restricted common units of Greenlane held by non-employee directors of Greenlane, whether vested or unvested, remained outstanding (and unvested, as applicable) in accordance with the terms of Greenlane’s equity plan covering each such award.

The Greenlane equity awards vesting acceleration was accounted for as a modification under ASC Topic 718, Compensation - Stock Compensation.

As described in "Note 3 - Business Acquisitions," in connection with the Mergers, we assumed the sponsorship of the KushCo Equity Plan. We do not intend to make future grants under the KushCo Equity Plan.

Equity-based compensation expense is included within "salaries, benefits and payroll taxes" in our condensed consolidated statement of operations and comprehensive loss. We recognized equity-based compensation expense as follows:
