Key Details

• Transaction code: M (exercise/conversion of derivative) — conversion of RSUs into shares.
• Shares acquired: 15,757 at $0.00 (conversion); matching disposition of 15,757 @ $0.00 shown as derivative.
• Total cash value reported from these entries: $0.00.
• Footnote: RSUs were granted May 21, 2025 under the 2020 Incentive Plan and vested/converted on May 14, 2026 (issuer’s annual meeting).

Context
This is a vesting/settlement of equity compensation (RSUs) rather than an open‑market purchase or sale. Such conversions typically reflect routine compensation vesting and do not by themselves indicate a buy or sell signal; no sale for cash was reported here. The matching derivative disposition entry at $0.00 appears to be reporting treatment related to the conversion/settlement.
