Polk Ryan 4

What Happened
Ryan Polk, Chief Financial Officer of SideChannel, had 25,745 restricted stock units (RSUs vest) on March 2, 2026; 10,602 of those shares were withheld to cover taxes (code F), resulting in 15,143 shares issued to him (25,745 × $2.20 closing price = $56,639 value related to the vesting event). On March 16, 2026 he was granted 35,574 RSUs (code A) valued at $2.01 per share, a notional value of $71,504. The March 2 withholding is a routine tax-related disposition, not an open‑market sale.

Key Details

• Transaction dates and prices:
  • 2026-03-02: 25,745 RSUs vested; closing price $2.20; $56,639 shown (10,602 shares withheld for taxes; 15,143 shares issued) — code F (tax withholding).
  • 2026-03-16: 35,574 RSU grant at $2.01/share; $71,504 notional value — code A (award/grant).
• Shares issued vs. unvested: 15,143 shares were issued to Polk on vesting; 35,574 RSUs were newly granted and are unvested per the award terms.
• Vesting schedule for the grant: the 35,574 RSU award vests one‑third on each of the next three March first business days (per filing footnote).
• Beneficial ownership totals: the filing’s footnotes reference total beneficial ownership after a Jan 22, 2026 1-for-52 reverse split and after these transactions (see F1 and F4 in the filing for amounts).
• Filing date/timeliness: Form 4 was filed March 18, 2026 covering transactions on March 2 and March 16; the March 2 vesting was reported after the transaction date (late reporting noted).

Context: The March 2 activity was a vesting event with shares withheld for taxes (routine "cashless" withholding), which is common and does not indicate an open‑market sale. The March 16 entry is a standard time‑based RSU grant with multi‑year vesting, which is an issuance of compensation rather than a purchase. All details and exact post‑transaction beneficial ownership numbers are in the filing footnotes and Form 4 itself.
