Key Details

Filing date: April 8, 2026 (Form 4 accession 0001193125-26-148613). Transactions dated March 20, 2026 and April 6, 2026.
Specifics:
- 3/20/2026: Grant/award — 323,173 shares acquired @ $0.00 (award).
- 3/20/2026: Grant/award (derivative) — 727,140 derivative units acquired @ $0.00.
- 4/06/2026: Exercise/conversion (M) — 70,183 shares acquired @ $0.00 (converted from derivative).
- 4/06/2026: Payment of tax liability (F) — 21,301 shares withheld/disposed @ $0.91 = $19,341.
Shares owned after the reported transactions are not specified in the filing.
Notable footnotes:
- RSUs vest over four years (1/16 vesting May 20, 2026; remaining vest in equal quarterly installments), each RSU converts to one share (F1, F4).
- The 21,301-share disposition was a tax withholding to satisfy RSU vesting obligations from an earlier RSU grant (original RSU grant reported April 6, 2022) (F2, F5).
- An option/derivative has a similar vesting schedule (1/16 on May 20, 2026, then quarterly) (F3).
Filing does not indicate a 10b5-1 plan or other sale program; the withheld shares relate to tax obligations, not an open-market sale.

Context

This was not an open-market sale by the insider—21,301 shares were withheld by the company to cover taxes on vesting RSUs (common practice when RSUs vest). The exercise/conversion converted derivative instruments into shares rather than generating a cash proceeds sale.
Awards and exercises reported here are routine equity compensation actions; they reflect grant and vesting mechanics rather than a clear bullish or bearish personal trade signal.
