Key Details

  • Transaction date: 2026-05-22.
  • Cash purchase: 14,235 shares at $1.41 per share = $20,000 total.
  • Additional entry: 14,235 shares at $0.00 (reported as a derivative/related purchase).
  • Footnote: The reporting person purchased these shares directly from the issuer in a private placement, exempt from Section 16(b) under Rule 16b-3(d).
  • Shares owned after transaction: not specified in the provided filing details.
  • Filing date: 2026-05-27 for a 2026-05-22 transaction — Form 4s are normally due within 2 business days, so this appears to have been filed after that window.

Context

  • The primary transaction code is P = Purchase, which is a direct buy (often seen as a more informative signal than routine sales). The $0.00 entry represents a derivative or related issuance; the footnote clarifies the shares were acquired in a private placement directly from the issuer and are exempt under Rule 16b-3(d). No evidence in the provided data indicates an immediate sale, tax-withholding, or 10b5-1 plan.
