Context

• These were prearranged sales under a 10b5-1 plan, which are routine mechanisms executives often use to sell company stock on a scheduled basis and do not by themselves indicate a change in insider sentiment.
• For retail investors, purchases typically carry more positive informational weight than routine sales; this filing documents a planned disposal.
