Chad Everett Harris - 13 Apr 2022 Form 4 Insider Report for Riot Blockchain, Inc. (RIOT)

Footnote F1

Pursuant to the Riot Blockchain, Inc. 2019 Equity Incentive Plan, as amended, (the "Plan") the Reporting Person was granted performance-based restricted stock unit ("PSUs") as of August 12, 2021, which are eligible to vest contingent upon the Issuer's achievement of certain performance criteria during the performance period ending on December 31, 2023. Each PSU represents a contingent right to receive one share of the Issuer's common stock, no par value per share, ("Common Stock") subject to any net settlement permitted under the Plan and approved by the Issuer's Compensation and Human Resources Committee (the "Committee"), following vesting and settlement by the Issuer.

Footnote F2

On April 13, 2022, the Committee determined that the performance criteria corresponding to 14,000 PSUs had been achieved as of March 31, 2022. Therefore, 14,000 of the PSUs originally awarded to the Reporting Person became vested as of April 13, 2022. Upon vesting, the Issuer records PSUs as Restricted Stock Units, which are eligible to be settled by the Issuer in shares of its Common Stock on a one-for-one basis, subject to any net settlement for taxes as permitted under the Plan and as approved by the Committee. Accordingly, the award of 14,000 Restricted Stock Units reported on this Form 4 represents the vesting of 14,000 PSUs awarded to the Reporting Person on August 12, 2021.
