"Purchase in open market or private transaction"

Rule 10b5-1 trading plan regulatory

"No Rule 10b5-1 trading plan is reported for these purchases"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

Were Michael Edell’s SNES share purchases under a Rule 10b5-1 trading plan?

No. The filing indicates the Rule 10b5-1 checkbox is not marked, so these 2,000-share open-market purchases by CEO Michael Edell are not reported as being made under a Rule 10b5-1 trading plan.

Is the Form 4 for SNES reporting any insider sales?

No. The Form 4 for SenesTech shows 2,000 shares of common stock were purchased by CEO Michael Edell and reports no insider sales or other types of dispositions in this filing.

Does the Form 4 disclose Michael Edell’s total SNES holdings after these purchases?

No. For each of the two transactions, the field for shares held following the transaction is not reported, so the filing does not state Michael Edell’s aggregate SenesTech common stock holdings after these purchases.
