What Happened

Jonathan Gillis, CAAO and PAO of MapLight Therapeutics (MPLT), had 22,050 shares withheld by the company on 2026-01-27 to satisfy tax withholding obligations related to the settlement of restricted stock units. The withholding occurred at $17.98 per share for a total value of $396,459. This was a tax-withholding disposition (code F), not an open-market sale.

Key Details

Transaction date: 2026-01-27 (reported on Form 4 filed 2026-01-29)
Shares withheld: 22,050 at $17.98 per share; total value ≈ $396,459
Transaction code: F — payment of exercise price or tax liability (tax withholding on RSU settlement)
Shares owned after transaction: not specified in the provided summary
Footnote: The shares withheld satisfy tax withholding for RSU settlement. Remaining shares held by the reporting person are subject to a 180-day IPO lock-up following the final prospectus dated October 26, 2025 (per footnote).
Filing timeliness: Report appears timely (transaction 1/27, Form 4 filed 1/29).

Context

This was a routine tax-withholding event tied to RSU settlement (common when restricted shares vest). It is not an open-market sale and should not be read as a direct bearish signal by the insider. The lock-up restriction noted in the filing means many of the reporting person’s remaining shares may still be restricted from sale for the specified 180-day period.
