Insights

Securities Analyst

TL;DR: Insider sales were executed under a Rule 10b5-1 plan; quantities and weighted-average prices disclosed, suggesting pre-planned disposals.

The reporting person, identified as the CFO, sold 205 and 393 shares in automated transactions under a 10b5-1 trading plan adopted at least 90 days earlier. The filing provides weighted-average prices and ranges for the multiple trades, and reports post-transaction beneficial ownership balances. From a disclosure and governance standpoint, the use of a pre-existing 10b5-1 plan reduces the likelihood that these trades were based on nonpublic information. The volumes disclosed are small relative to typical market-cap insider considerations and are documented with footnotes offering further granular price breakdowns on request.
