Context

• Sales by insiders can be for many personal or tax-planning reasons and do not necessarily indicate a change in company outlook; purchases are generally considered more informative about insider sentiment.
• The footnote about unvested RSUs means some reported share amounts are tied to restricted units that have not yet vested; that can affect when shares are actually deliverable.
