Context

• These filings reflect routine equity compensation activity: RSUs vesting, new RSU awards, and shares sold to cover tax withholding. Such sales are common and do not necessarily signal the insider’s market view.
• The derivative code "M" here indicates conversion/exercise of restricted units into common shares rather than an option purchase for cash. The immediate sale of some shares to cover taxes is a cashless/tax-withholding action by the issuer.
