| F6 | In addition to the 811,449 shares and 62,302 shares reported in Column 5, as of March 1, 2026, 1,007,500 deferred RSUs granted to Mr. DeMarco, representing non-qualified deferred compensation, have vested but remain subject to a previously agree to 5-year deferral period before issuance and release, which substantially all subject RSUs are scheduled to be released by January 2029. An additional 600,000 RSUs granted to Mr. DeMarco are currently unvested and will only vest upon achievement of applicable vesting terms described in our proxy statement on Schedule 14A filed with the SEC on April 4, 2025. In addition, 300,000 RSUs were granted January 3, 2026, where 150,000 RSUs vest ratably over a five-year period, and the other 150,000 are performance-based RSUS that vest when certain performance criteria are met (similar to the vesting terms described in the April 4, 2025 proxy statement). Each RSU represents a contingent right to receive one share of the Company's common stock. |
