Insights

Corporate Governance Expert

Director received equity grant of 1,022 shares under standard plan.

This filing records a non-employee director equity award: 1,022 Class A shares granted under Appian's 2017 Equity Incentive Plan and the company’s Non-Employee Director Compensation Policy.

Because the grant is described as issued under the board‑approved policy amended on December 18, 2020, this appears to be a routine compensation action rather than a market transaction. The director’s total beneficial ownership after the grant is 43,086 shares.
