Context

• The filing reports an exercise/conversion and a matching disposition of the same number of derivative shares; the zero-dollar prices indicate these were derivative/award-related settlements rather than open-market purchases or sales. The 9,718 RSUs represent a contingent right to receive shares and—per the filing—were 100% vested as of May 13, 2026. These kinds of grant/exercise filings are common for executives and directors and do not by themselves indicate a buying or selling signal by the insider.
