The following table summarizes our RSU activity for the six months ended June 30, 2026. RSUs are issued as part of the Innovative Industrial Properties, Inc. Nonqualified Deferred Compensation Plan (the “Deferred Compensation Plan”), which allows a select group of management and our non-employee directors to defer receiving certain of their cash and equity-based compensation. RSUs are subject to vesting conditions of the Deferred Compensation Plan and have the same economic rights as shares of restricted stock under the Incentive Plans:
