Context
- This was an option exercise paired with substantial open‑market selling on the same day. The exercise involved paying the $1.50 strike for 170,000 options; the large open‑market sales generated roughly $6.64M in proceeds. The reported $0.00 derivative disposition is tied to the exercise per the filing footnote (F1) and may reflect conversion/settlement actions described in the filing.
- Sales conducted under a pre‑arranged 10b5‑1 plan are generally planned in advance and are not, by themselves, a clear signal of the insider’s current view of the company.
- All figures are taken from the Form 4 (Accession 0001493152-26-004580); for precise trade‑by‑trade prices the reporting person has agreed to provide details to the SEC staff or security holders upon request.
