2020 Plan

The 2020 Plan was adopted in April 2020 and provides for the granting of stock options, restricted stock, restricted stock units, stock appreciation rights, performance awards, other stock-based awards and dividend equivalent rights to employees, directors and consultants of Archrock. Under the 2020 Plan, the maximum number of shares of common stock available for issuance is 8,500,000. Each stock-settled award granted under the 2020 Plan reduces the number of shares available for issuance by one share. No additional grants may be made under the 2013 Plan following the adoption of the 2020 Plan. Previous grants made under the 2013 Plan continue to be governed by that plan and the applicable award agreements.
