Key Details

Transaction date: 2026-03-04; Form filed: 2026-03-06 (appears timely).
Reported as an award/acquisition (derivative) — 836 units at $0.00.
Shares owned after the transaction: not specified in the provided excerpt.
Relevant footnotes in the filing indicate these awards are RSUs under the Company’s 2018 Stock Incentive Plan (see footnote F4) and are subject to vesting and continued employment (see additional footnotes F5–F8 for various vesting schedules). Other footnotes in the filing reference depositary-share transactions and option vesting schedules (F1–F3), but those appear to describe different awards/transactions in the filing.

Context

These are derivative awards (restricted stock units) that represent a right to receive common shares upon vesting; they carry no purchase price at grant and are typically subject to time- or service-based vesting. This was a grant (compensation), not a sale — it does not by itself indicate insider buying or selling for investment purposes.
