Context
RSU grants are common executive/director compensation and do not by themselves indicate buying or selling sentiment in the market. The shares will only be issued if/when the RSUs vest under the stated conditions. If you track insider timing, note the filing date vs. transaction date (filed four days after the grant)—Insiders generally must file Form 4 within two business days, so review the full filing for any explanation.
