Context

• The sale was executed by the CRT trustee under a pre-established 10b5-1 plan, which generally means the disposition followed instructions set in advance and is not a spontaneous insider sale. Sales by trust trustees or under 10b5-1 plans are common for estate planning and liquidity needs and do not, by themselves, indicate the insider’s current market view.
