Context These were open-market purchases (purchase code P), meaning the insider bought existing shares rather than receiving awards or exercising options. As a director (not identified here as a 10% owner), Elliott’s buys are factual disclosures — they may be of interest to investors but do not by themselves explain the insider’s motives. The late filing is notable and may affect how quickly the market could have reacted to these transactions.
