Key Details

  • Transaction date: February 6, 2026; Form 4 filed February 10, 2026 (filing date shown; no late-filing flag indicated in the report).
  • Award: 80,000 derivative shares, acquisition price $0.00 (reported value $0).

Context

This is a compensatory equity grant to an executive (not an open-market trade). The $0.00 price in the filing reflects how the award is reported; the award's economic or tax value depends on the award type (options, RSUs or similar) and plan terms. Such grants are common as part of executive compensation and do not by themselves indicate a buy/sell signal.
