Context

• A gift (G) is a non-sale disposition and does not generate cash proceeds; it generally should not be read as a bullish or bearish signal about the insider’s view of the company.
• The footnotes show material unvested equity awards tied to service and performance, which reflect ongoing compensation arrangements rather than open‑market trading.
